Degree, is effectively reduced the pain of patient.
In the present embodiment, the second end of catheter body has position limiting structure, in position limiting structure for making expandable balloon 5
It is expanded towards the direction of the axis of catheter body.As shown, the position limiting structure in the present embodiment is specially arc-shaped side 6, it is expansible
The part edge of 5 opening of sacculus is connected on arc-shaped side 6, and part edge is connected on the inner wall of catheter body, arc-shaped side 6 to
Close to the direction bending of the axis of catheter body.Arc-shaped side 6 is made by elastic material, when expandable balloon 5 is made in inflating medium
When with lower expansion, the also prolonged expansion therewith of arc-shaped side 6.Also, after injecting inflating medium in expandable balloon 5, arc-shaped side 6
Outer end face with expandable balloon 5 is arcwall face 51, and stomach tube is convenient in distal end of the expandable balloon 5 as stomach tube, in this way setting
It is inserted into human body, reduces the sense of discomfort in insertion process.
The concrete application step of the specific implementation of open and close type stomach tube in this specific embodiment are as follows:
1, enough liquid inflating mediums are injected separately into the by the first subchannel 41 and the second subchannel 42
One bulbec capsule and the second bulbec capsule expand the first bulbec capsule and the second bulbec capsule sufficiently and the second end of seals primary passage 2
Opening, and inflating medium is made to fill up two subchannels；
2, stomach tube is inserted into human body, during insertion, using the liquid in ultrasonic sensor detection sacculus, that is,
It says, in the insertion process of stomach tube, is guided using ultrasound, while can also be developed by X and be guided；
3, after the end of stomach tube reaches target position, nutriment or other liquid are injected into main channel 2, it is main logical
The substance in road 2 is flowed into human body by the side through hole 3 in catheter body 1.
That is, two sub- sacculus are in the second end of swelling state and seals primary passage in normal use stomach tube
Opening.
When bulky grain or the nutriment of high concentration blocking main channel, by inflating medium, all export or part are led
Out, two sub- sacculus is made to be in non-expansion state or non-fully swelling state, so that the opening of the second end of main channel is opened, from
And convenient for carrying out flush clean to main channel, it solves the problems, such as difficult cleaning of after stomach tube is blocked.
When needing high-intensitive negative pressure drainage, two sub- sacculus is made to be in non-expansion state or non-fully swelling state,
To open the opening of the second end of main channel, drainage efficiency is increased.
When needing to convey substance into human body from the second end of main channel, master can be opened by two sub- sacculus of control
The opening of the second end in channel can control the amount of the inflating medium in bulbec capsule to control the degrees of expansion of bulbec capsule, thus
Further control the openings of sizes of the second end of main channel.
It is some application methods in the present embodiment above, when carrying out specific embodiment, those skilled in the art can root
According to needing to carry out adaptation operation.
It should be noted that refer to along the axial setting of catheter body can be from leading by the liquid of main channel for main channel
The axial second end of the axial first end flow direction of tube body, in the present embodiment, main channel is coaxial with catheter body, at other
In embodiment, the axis of main channel can be deviateed with the axial direction of catheter body, and certainly, main channel can also be set as curved
The main channel in channel, this form belongs to the protection scope of the application.
Similarly, refer to along the axial setting of catheter body can be from conduit sheet by the inflating medium of wing passage for wing passage
The axial second end of the axial first end flow direction of body, in the present embodiment, the axis of wing passage and the axis of catheter body are flat
Row, in other embodiments, the axis of wing passage can be deviateed with the axial direction of catheter body, and certainly, wing passage can be with
It is set as curved channel, the wing passage of this form belongs to the protection scope of the application.
In addition, wing passage can be set to multiple in other specific embodiments of the open and close type stomach tube of the utility model
One subchannel and multiple second subchannels, sacculus also can be set to three or three or more bulbec capsules, as long as it can be
The opening that the second end of main channel is opened when not expanding completely, the opening of the second end of seals primary passage in complete expansion
It can；The set-up mode of side through hole can be adjusted according to actual needs；The specific structure and composition material of position limiting structure can bases
Actual needs adjustment, it is of course also possible to be not provided with position limiting structure；The material of inflating medium can according to need selection, herein not
It repeats one by one again.
Specific embodiment two
This specific embodiment discloses a kind of another specific embodiment of open and close type stomach tube of the utility model, knot
Structure and specific embodiment one are essentially identical, the difference is that only, in the present embodiment, wing passage and the specific of dilating sacculus set
Set mode difference.
As described in Fig. 5,6, in the present embodiment, wing passage 4 and expandable balloon 5 are provided only with one, also, expansible
Sacculus 5 is located in main channel 2, and when expandable balloon 5 is in fully expanded state, expandable balloon 5 expands in main channel 2
And the opening of the second end of main channel 2 is blocked, and when expandable balloon 5 is unexpanded or not expansion completely, the second end of main channel 2
Opening still keep opening-wide state.
Furthermore, it is desirable to which it is noted that conduit will not be blocked when the expandable balloon 5 in the present embodiment is in swelling state
Side through hole 3 on ontology 1.
Certainly, other than the set-up mode in specific embodiment one, two, dilatation balloon and wing passage can also be as needed
The adjustment for carrying out structure, no longer repeats one by one herein.
Specific embodiment three
This specific embodiment discloses a kind of application method of open and close type stomach tube disclosed in specific embodiment one, is using
Before, inflating medium is injected into expandable balloon by wing passage, expandable balloon sufficiently expands the second of simultaneously seals primary passage
The opening at end.Also, the inflating medium of injection is liquid, and inflating medium expands two sub- sacculus sufficiently, and inflating medium fills
Full two subchannels.When operating in this way, it can be guided by detection device during in stomach tube insertion human body, thus
Intubation efficiency can be improved, reduce the sense of discomfort of patient.
It should be noted that above-described embodiment can be freely combined as needed.The above is only the utility model
Preferred embodiment, it is noted that for those skilled in the art, do not departing from the utility model principle
Under the premise of, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the protection scope of the utility model.
