Herein, the downstream is the statement of a flow direction relative to fluid, in one embodiment, the stream The flow direction of body is originated from fluid source, via the extrusion infusing pipeline system flow to target such as patient.The phase in the downstream Opposite direction is upstream.

An object of the present invention is to need to detect whether that upstream occlusion occurs.The upstream occlusion refers to be driven in fluid During device drives the flow downstream in the extrusion infusing pipeline system to flow, occur in the pipeline of test point upstream Traffic congestion event.Such as common upstream occlusion point can occur in the pipeline of valve system 151 and its upstream.

In order to which the purpose for realizing detection upstream occlusion of the present invention proposes in an embodiment of the present invention A kind of upstream occlusion detection device.Fig. 3 is a kind of fluid control devices of the present invention containing upstream occlusion detection device Schematic diagram.The upstream occlusion detection device is applied is driving the fluid in soft pipeline to be flowed with fluid drive apparatus In fluid control devices.Fluid control devices described in Fig. 3 increase on the basis of being the fluid control devices described in Fig. 1 and Fig. 2 Upstream detection device.The upstream occlusion detection device specifically include that protrusion means 31, raised respective sensor 32 and Identified upstream module 33.

The specific location of the protrusion means 31 is characterized in: when the protrusion means 31 are in position, and described soft Matter pipeline 152 is under installation condition, and the first side of 301 pairs of the convex top of the protrusion means soft pipeline 152 implements to support Pressure makes the first side of the soft pipeline 152 generate corresponding bending at the convex top 301.The protrusion means are in shape in place State refers to that fluid control devices are in the state of normal work on the whole.The position for why saying protrusion means, be because The protrusion means can be fixed on the shell of fluid control devices in one embodiment, embodiment as shown in Figure 3；? In other embodiment, the protrusion means can also be with the fluid control devices split settings, i.e. the protrusion means can be with It is arranged on the lid of the fluid control devices, when on cover cap to shell, the protrusion means are just in position, This embodiment refers to shown in Fig. 9 a to Figure 10 c.

Such as in this Fig. 3, protrusion means 31 specifically be can be set in the soft of the upstream of the pump impeller 11 of fluid drive apparatus On the installation path of pipeline；If Fig. 5 a is the partial enlarged view of soft pipeline at protrusion means as described in Fig. 3, referring to Fig. 5 a, this reality It applies protrusion means 31 described in example to be fixed on shell, just already belongs to position, when the soft pipeline 152 is in Under installation condition, the first side of 301 pairs of the convex top of the protrusion means soft pipeline 152 implements to compress, and makes the soft pipe First side on road 152 generates corresponding bending at the convex top 301.First side refers to soft pipeline 152 towards described convex Play the side of mechanism 31, should the description of " first side " be rather than to indicate important journey for mutually distinguishing with " second side " hereinafter Degree and sequence and each other existing premise etc..In one preferred embodiment of the invention, the of the soft pipeline 152 Side this it is convex top 301 at caused by bending angle be an obtuse angle, be also possible to other angles in other embodiments certainly Degree.

Raised respective sensor 32 is placed in the convex top of the protrusion means when protrusion means 31 are in position 301 corresponding position will test result transmission for detecting the deformed state of the soft pipeline 152 at the convex top 301 To identified upstream module 33.The protrusion respective sensor 32 can be photoelectric sensor or ultrasonic sensor or it is other can be with Detect the sensor of soft pipeline change in shape.Fig. 4 is a kind of left view of upstream occlusion detection device described in Fig. 3.Referring to Fig. 3 And Fig. 4, which is placed in the corresponding lateral location in convex top 301 of the protrusion means, convex described in Fig. 3 Playing the portions in phantom that respective sensor 32 is blocked by soft pipeline 152 and protrusion means 31 indicates.The protrusion respective sensor 32 detection zone covers bending part of the soft pipeline 152 at the convex top 301 of protrusion means, by photoelectricity, ultrasound, Or other induction modes detect the deformed state of the soft pipeline at the convex top 301, such as the soft pipeline narrows or becomes The states such as thick.

Identified upstream module 33 can realize that information communicates with the raised respective sensor 32, for according to the protrusion The testing result that the transmission of respective sensor 32 comes is judged that the soft pipeline at the convex top 301 narrows to specified numerical value, Then determine that upstream occlusion occurs.The identified upstream module 33 specifically can be a kind of logic judgment processing module, can be set The inside of the fluid control devices, as long as being able to achieve its logic judgment processing function, the specific implementation present invention is not It limits, such as can be with software realization or realized with the mode of hardware realization or software and hardware combining.

It is as shown in Figure 5 a a kind of form of the soft pipeline 152 when there is no upstream occlusion, in this form Under, under the driving of the pump impeller 11, the interior fluid of the soft pipeline 152 is in normal flowing.Fig. 5 b is in generation A kind of form schematic diagram of soft pipeline when trip blocking.Referring to Fig. 5 b, in case of upstream occlusion, such as in the valve machine Blocking occurs in structure 13 or blocking etc. occurs in the upstream of valve system 13, at this time since pump impeller 11 continues to drive soft pipeline Internal flow downstream flowing, then due to the reduction of the fluid in the soft pipeline of 11 upstream of pump impeller, upstream is not flowed newly again The supplement of body, then the soft pipeline that will lead to 11 upstream of pump impeller, which can more quickly be shunk, to narrow；If without spy of the present invention The construction of different protrusion means, then soft pipeline is when upstream occlusion, which occurs, leads to deformation, it may occur that random movement can not utilize Sensor is detected.Due to the construction of protrusion means of the invention, the first side of soft pipeline is compressed by convex top 301, no But make soft pipeline 152 relatively stable when upstream occlusion occurs, the position of the first side of soft pipeline 152 is basically unchanged, And the other side, that is, second side can relatively quickly be drawn close to the first side, so that soft pipeline 152 is curved at the convex top 301 The raw apparent morphologic change of folding part distribution, i.e., significantly narrow；This apparent morphologic change is highly convenient for detecting, even if sharp It may also detect that this apparent morphologic change with the sensor of lower cost.Therefore, described convex when upstream occlusion occurs Playing respective sensor 32 can accurately and timely detect that the apparent form of soft pipeline generation at the convex top 301 changes Become, and send the synchronizing information of this morphologic change to the identified upstream module 33, identified upstream module 33 so as to Judge that upstream occlusion occurs in time.

Fig. 6 is a kind of top cross-sectional view of protrusion means described in Fig. 5 a.In an advantageous embodiment, as shown in fig. 6, institute The convex top 301 of protrusion means 31 is stated, can be a kind of concave arc shape structure, so as to be fitted closely with soft pipeline 152.It is this On the one hand concave arc shape structure can play stable effect to soft pipeline 152, i.e., when soft pipeline 152 occurs for upstream occlusion Soft pipeline is avoided to generate large-scale random movement when obvious deformation, on the other hand can play makes when upstream occlusion occurs Soft the first side of pipeline (side contacted with the convex top 301) is relatively fixed, and the unexpected of relative displacement occurs for second side Effect, this effect can be accurately detected with more convenient sensor, improve the accuracy of detection.Certain Fig. 6 institute The cross-section structure for stating the convex top 301 of protrusion means 31 is that more preferably embodiment, cross-section structure can also use one kind Other shapes of structure.

More specifically, the soft pipeline that the identified upstream module 33 judges at the convex top 301 narrows to specified Numerical value then determines that upstream occlusion occurs.Specified numerical value herein can be and rule of thumb preset a numerical value；It can also be with It is a ratio value, i.e. the width of the soft pipeline from convex top 301 shown in Fig. 5 a narrows to designated ratio (such as 1/4 or 1/5 Deng)；It is also possible to numerical value when one blocking of measurement, and stores, determines if reaching the numerical value in operation later Upstream occlusion occurs.

In order to which pipeline soft when further making to occur upstream occlusion maintains a relatively stable state, sensor detection is improved Accuracy.In an advantageous embodiment, the upstream occlusion detection device can further include at least one supporting element, It is oppositely arranged with the convex top of the protrusion means；The position feature of the supporting element is: being in and has installed in the soft pipeline Under state, the top of the supporting element compresses second side implementation of the soft pipeline, makes the soft pipeline relative limit Between the supporting element and the convex top of the protrusion means；First side and the second side direction are opposite.

At least one described supporting element is arranged between the convex top of the protrusion means and pump impeller.The convex top and the branch Support member generates contrary pressure to the soft pipeline, so that the installation condition of soft pipeline is relatively stable.Further Preferred embodiment in, the supporting element can be two, be separately positioned on the two sides up and down on the opposite of the protrusion means.

It is illustrated in figure 7 a kind of schematic diagram of the further upstream occlusion detection device containing supporting element.Referring to figure 7, in the opposite side in the convex top 301 of the protrusion means 31, supporting element 71 and supporting element 72, supporting element 71 and supporting element are set 72 are separately positioned on the two sides up and down of 301 horizontal extension lines of the convex top；The top of supporting element 71 and supporting element 72 is to described soft Second side (other side of side is contacted with the convex top 301) of matter pipeline is implemented to compress, and makes the soft pipeline relative limit In the supporting element 71 and supporting element 72 and between the convex top 301 of the protrusion means.This structure, soft pipeline with The contact portion A of supporting element 71, the contact portion C with the contact portion B of supporting element 72 and convex top 301, all in relatively-stationary shape State, when upstream occlusion, it is only that the opposite contact portion C side i.e. position E (is located at soft that the most apparent region of morphologic change, which occurs, Second side of pipeline), the protrusion respective sensor 32 detects position E, when upstream occlusion occurs, position E It can occur significantly to be displaced (for the direction shown in Fig. 7) from left to right, even lower-cost sensor can be also easy to It detects this obvious displacement, and then can identify upstream occlusion.Therefore this design feature not only increases detection upstream Timeliness, sensitivity and the accuracy of blocking, and cost is relatively low.

It is similarly similar with the horizontal section of the protrusion means, the supporting element 71 and supporting element 72 and soft pipeline contact The horizontal section in portion is also possible to a kind of concave arc shape structure, so as to fit closely with soft pipeline 152.

In the above-described embodiments, the protrusion means, the supporting element and the fluid drive apparatus are all disposed within described The shell side of fluid control devices.

The protrusion respective sensor 32 can use the sensor of monomer structure, and in this case, the protrusion is corresponding to be passed Sensor is placed on the shell of the fluid control devices, or is placed on lid but is the need to ensure that the lid under lid conjunction state The detection range of the protrusion respective sensor 32 can cover the soft pipeline at the convex top 301.

It certainly, can if the protrusion respective sensor uses emission part and receiving unit for the sensor of separate structure The first part of the protrusion respective sensor to be arranged on the shell of fluid control devices, and second part is then arranged in institute Shell to be stated to correspond on lid, when on cover cap to the shell, the second part is just opposite with first part, so as to To realize the detection function of raised respective sensor.If Fig. 8 is the schematic diagram of another embodiment at visual angle shown in Fig. 6, referring to Fig. 8, the protrusion respective sensor is split type, i.e. first part 321 and second part 322, and wherein first part 321 is arranged On shell 800, second part 322 is arranged on lid 810；When in use, lid 810, second part 322 and are closed A part 321 is just opposite, is in position, and detection range between the two covers the soft pipeline at convex top 301 152。

In a further embodiment, the protrusion means can not also be set simultaneously with fluid drive apparatus (especially pump impeller) It sets in the shell side of fluid control devices, but is arranged on the lid of fluid control devices.

Fig. 9 a and Fig. 9 b are that a kind of showing for upstream occlusion detection device on the lid of fluid device is arranged in protrusion means It is intended to, Fig. 9 a is front view, and Fig. 9 b is left view.

The lid 810 includes two states: one is opening states；Another kind is lid conjunction state, i.e. the lid of lid 810 arrives State on the shell 800.Lid 810 is in an open state as described in Fig. 9 a, and the protrusion means 31 are arranged in the lid 810 inside.Lid 810 shown in Fig. 9 b is in the relatively parallel partition state with shell 800, can from the state To the relative status of the protrusion means 31 and the supporting element 91 and 92 on the shell.

Figure 10 a is a kind of partial enlargement diagram of Fig. 9 b, and the rotation lid of lid 810 described in specially Fig. 9 a, which closes, arrives institute The schematic diagram of 31 present position of protrusion means when stating on shell 800；Figure 10 b be described in Figure 10 a locally in upstream occlusion Schematic diagram.When lid is closed onto shell 800 lid 810 completely, the protrusion means 31 are just in position.The embodiment In protrusion means 31 position have following position feature, it may be assumed that when the protrusion means 31 are in position, the protrusion machine Structure 31 is located on the installation path of the soft pipeline of 11 upstream of fluid drive apparatus pump impeller, at the soft pipeline 152 (certain erection sequence is that first installation contains the extrusion infusing pipeline system of the soft pipeline, then covers described under installation condition Lid 810), the first side of 301 pairs of the convex top of the protrusion means 31 soft pipeline 152 implements to compress, and makes the soft pipeline 152 the first side generates corresponding bending at the convex top 301.In the present embodiment, first side refers to soft pipeline 152 sides contacted with the convex top 301, the other side, that is, supporting element 91 and 92 opposite with first side and soft pipeline 152 The side of contact is second side.

Figure 10 c is a kind of top cross-sectional view of protrusion means described in Figure 10 a.In an advantageous embodiment, such as Figure 10 c institute Show, the section on the convex top 301 of the protrusion means 31 can be a kind of concave arc shape structure, so as to tight with soft pipeline 152 Closely connected conjunction.On the one hand this concave arc shape structure can play stable effect to soft pipeline 152, i.e., when upstream occlusion make it is soft Pipeline 152 occurs to avoid soft pipeline to generate large-scale random movement when obvious deformation, on the other hand can play make it is soft (i.e. with the side of the convex top contact) is relatively fixed for the first side of pipeline, and the unexpected effect of relative displacement occurs for second side, This effect can be accurately detected with more convenient sensor, improve the accuracy of detection.Protrusion described in certain Figure 10 c The cross-section structure on the convex top 301 of mechanism is that more preferably embodiment, cross-section structure can also use other shapes to one kind Structure.Similarly, similar with the horizontal section of the protrusion means, the supporting element 91 and supporting element 92 and soft pipeline contact The horizontal section in portion is also possible to a kind of concave arc shape structure, so as to fit closely with soft pipeline 152.

In such an embodiment, the position of the raised respective sensor 32 and the protrusion of embodiment described in Fig. 3-Fig. 8 are right Inductive sensing device position is different, but its function is consistent, and in this embodiment, which is placed in described convex Play the correspondence on (lid of lid 810 to the state on the shell 800) its convex top 301 when mechanism 31 is in position Position will test result and be transferred to identified upstream module for detecting the deformed state of the soft pipeline at the convex top 301 33。

It is described protrusion respective sensor 32 can use emission part and receiving unit for the sensor of separate structure, as Fig. 9 a with Shown in Figure 10 c, the emission part and receiving unit of the protrusion respective sensor 32 are located at the two sides of the soft pipeline 152.

The identified upstream module 33 can realize that information communicates with the raised respective sensor 32, for according to The testing result that the raised transmission of respective sensor 32 comes is judged that the soft pipeline at the convex top narrows to specified numerical value, Then determine that upstream occlusion occurs.In Figure 10 a and Figure 10 b, since line segment is more, in order to not influence the expression of main contents, Therefore identified upstream module is not drawn in Figure 10 a and Figure 10 b.

If Fig. 5 a and Figure 10 a show a kind of form of the soft pipeline 152 when there is no upstream occlusion, at this Under kind form, under the driving of the pump impeller 11, the interior fluid of the soft pipeline 152 is in normal flowing.Such as Fig. 5 b and Figure 10 b show a kind of form of the soft pipeline 152 when upstream occlusion occurs, under this form, in the pump impeller Under 11 driving, the soft pipeline 152 at the convex top 301 obviously narrows, i.e., the soft pipeline second side on convex top opposite is obvious To soft the first side of pipeline (i.e. with the side of convex top contact) displacement, the identified upstream module detects this displacement, thus Upstream occlusion has occurred in judgement accordingly.

Figure 11 a is a kind of schematic diagram of the identified upstream module in one embodiment；Referring to Figure 11 a, it is described on Swimming in identification module 33 may include: upstream occlusion logging modle 331 and upstream first judgment module 332.

The upstream occlusion logging modle 331, in the case where the soft line upstream blocks, according to institute It states the testing result that the raised transmission of respective sensor 32 comes and determines the current deformation numerical value of the convex soft pipeline pushed up at 301, Using the deformation numerical value as upstream occlusion deformation numerical value, the upstream occlusion deformation numerical value is recorded.Application scenarios herein are, when with After the extrusion infusing pipeline system is installed on the fluid control devices by family, a upstream occlusion, example can be artificially manufactured The fluid valve of valve system is arranged to closed position as will be described, or artificially blocks the upstream of the valve system, at this time Upstream occlusion can occur, for the soft pipeline meeting deformation at the convex top 301 to the state as shown in Fig. 5 b or Figure 10 b, protrusion is right Inductive sensing device 32 can detect the deformed state of the soft pipeline at convex top 301, and by the deformed state with corresponding communication shape Formula (such as electric signal, digital signal) synchronous driving to identified upstream module 33, triggers the upstream occlusion logging modle at this time 331 according to it is described protrusion to inductive sensing 32 transmit come testing result determine the current texturing variables of the soft pipeline at the convex top Value records the upstream occlusion deformation numerical value in case subsequent detection uses using the deformation numerical value as upstream occlusion deformation numerical value.Institute Stating deformation numerical value specifically can be there are many expression way: for example in one embodiment, can be soft at the convex top 301 Displacement of second side outer wall of pipeline relative to a certain reference point, such as this reference point can be set to the top on the convex top 301 Point is also possible to the boundary etc. of raised respective sensor detection range.Displacement d1 as described in Fig. 5 b or Figure 10 b can be A method of indicating the deformation numerical value, which is the boundary D with the raised respective sensor detection range for reference Point, the d1 can indicate the upstream occlusion deformation numerical value at this time.

Later, upstream occlusion caused by elimination is described artificially.When the fluid control devices run well, described in triggering Upstream first judgment module 332, the upstream first judgment module 332 be used for according to the raised transmission of respective sensor 32 come Testing result determines the current deformation numerical value of the soft pipeline at the convex top 301, if the deformation numerical value reaches the upstream and blocks up Stopper variable value then determines that upstream occlusion occurs, issues corresponding upstream occlusion signal.It is i.e. normal in the fluid control devices When operating, the deformed state of the soft pipeline at convex top 301 described in the protrusion respective sensor 32 meeting real-time detection, and will inspection It surveys result and is real-time transmitted to identified upstream module 33, the upstream first judgment module 332 in identified upstream module 33 is according to described Testing result determines the current deformation numerical value of the soft pipeline at the convex top 301 in real time, is recorded if the deformation numerical value reaches Upstream occlusion deformation numerical value, such as reach the d1, then determine that upstream occlusion occurs.
