The specific embodiment
Because the pressure size that the sickbed patients different parts is born is inequality, the time of its sustainable pressurized is also different, therefore air cushion can be divided into four zones, pressure-sensing unit 101 is set in each zone, according to the actual pressurized situation that pressure transducer sensed different control is realized in each zone of air cushion then, described four zones are: header area a1, back region a2, buttocks district a3, lower leg region a4, as shown in Figure 1a.
Shown in Fig. 1 b, in a kind of preferred implementation of the present utility model, the intelligence instrument that treats patients with decubitus comprises pressure-sensing unit 101, signal condition unit 102, timing sampling unit 103, control unit 104 and performance element 105.In turn, the signal output part of pressure-sensing unit 101 is connected with signal condition unit 102, and signal condition unit 102 is connected with timing sampling unit 103, and timing sampling unit 103 is connected with control unit 104; Control unit 104 is connected with performance element 105.
Pressure-sensing unit 101 can utilize various suitable pressure transducers to realize, preferably, in the present embodiment, pressure-sensing unit 101 can be a resistance strain type sensor, more preferably comprises a plurality of resistance strain type sensors that are arranged in a plurality of zones of air cushion.
Resistance strain type sensor is used to carry out pressure measxurement, and its operation principle is based on resistance strain effect and measures deformation.For metallic conductor, resistance value is not R during pressurized, and the relative change rate's of resistance expression formula is behind the pressurized:
In the formula: k0 is the sensitivity coefficient of metallic resistance silk, and ε is a strain value.
Because the pass of stress 6 and strain stress is σ=E. ε, the pass of pressure F and stress σ is F=σ .S again, and wherein E is the elastic modelling quantity (kg/mm2) of material, and S is the foil gauge sectional area, so the pass of foil gauge increased resistance value and pressure is:
During the foil gauge tension, the resistance of strain resistor increases, and during the foil gauge pressurized, the resistance of strain resistor reduces.Shown in Fig. 2 a, strain gauge transducer is connected into the full-bridge form, then the variable quantity of output voltage and strain resistor is linear, thereby also linear with pressure.
The pressure signal at each position of patient body of long-term bed changes slower, and system does not need the disturbing signal in the short time is responded, so the sampling time interval of 103 pairs of every roads, timing sampling unit transducing signal can be 60-90 second, is preferably 60 seconds.According to the number of used pressure transducer, multiplexer switch switches with predetermined switching frequency, thereby guarantees that every road signal is by the interval sampling of setting.
Preferably, the intelligence instrument that treats patients with decubitus also comprises data storage cell 106, and preferably, described data storage cell 106 is realized by the LabVIEW virtual instrument of installing in computer equipment and the computer.
Virtual instrument is based on the instrument of computer.The close combination of computer and instrument is an important directions of present instrument development.It is with the instrument computer of packing into, is support with general calculation machine hardware and operating system, realizes various instrumental functions.The main feature of virtual instrument has: adopted general hardware as far as possible, the difference of various instruments mainly is software; Give full play to the ability of computer, powerful data processing function is arranged, can create instrument with better function; The user can define and make various instruments according to the needs of oneself.
Virtual instrument is actually a data collecting system according to instrument demand tissue.The rationale that virtual instrument relates to mainly contains computer data acquiring and Digital Signal Processing.In this field, using comparatively widely, computer language is the LabVIEW of America NI company at present.
The setting of serial ports in the LabVIEW software (for example RS232) should be consistent with the serial ports parameter of single-chip microcomputer.The type of being read in the pressure data of virtual instrument by serial ports is a character type, at first character type data is converted to metric integer, one-dimension array after will changing then is converted to 2 capable dimension groups of 18 row n, wherein, totally 18 pressure transducers, the sampled value of corresponding each the passage transducing signal of the data in every row.The data of each pick off in the zone that mattress is different deposit different files in, are set to guarantee the synchronous of data acquisition and storage time delay.The data of all records can be kept at the form of EXCEL numerical table under the specified file.
Preferably, the intelligence of the present utility model instrument that treats patients with decubitus also comprises alarm unit 107, and described alarm unit 107 is connected with control unit 104.Described alarm unit 107 can be buzzer, alarm lamp, voice prompting device or other alarming devices that is fit to.
In one embodiment of the invention, can the treat patients with decubitus circuit of instrument realizes that block diagram is shown in Fig. 1 c.
Each regional pressurized situation of air cushion can be analyzed by the data to this each pick off of zone of having stored and obtain.If in the time that sets, do not detect the variation of the position of maximum pressure spot in this zone, then system will produce warning, and this zone massaged, otherwise system will think the patient changed voluntarily should the zone supporting point, this one need not massage, and system will begin that this zone is carried out new one and take turns pressure detecting and analysis.In this case, the intelligent decision of system will reduce the number of times of performance element operation, thereby reduce the interference to patient's rest.
Can show the detected pressure signal of all the sensors in each zone in the virtual instrument interface, in can the preserve separately different data file of the transducing signal in each zone, the sustainable pressurized time in each zone can according to circumstances be set by the medical worker.
In one embodiment, variation has taken place in the intelligence supporting point that instrument detects the buttocks district that treats patients with decubitus in two hours, report to the police and control signal so do not produce; And the intelligence instrument that treats patients with decubitus detects patient's head and back continuous compression three hours, then sends the alarm signal and the control signal of respective regions, and header area and back region are massaged.
In this utility model, be distributed in each regional pressure transducer of air fluidized bed detect the pressure signal that obtains through amplify and sampling after, be sent to computer by serial ports.Utilize the LabVIEW virtual instrument installed in the computer to the pressure data storage of classifying, and go out the zone of the long-time pressurized of human body, thereby the control air fluidized bed is massaged in time to it according to analytical judgment to each areal pressure signal.Experiment shows this instrument that treats patients with decubitus pressurized situation of human body that can judge rightly out, thereby has realized the control of decubital ulcer effectively.
Although this utility model is described by above-mentioned preferred implementation, its way of realization is not limited to above-mentioned embodiment.Should be realized that under the situation that does not break away from this utility model purport, those skilled in the art can make different variations and modification to this utility model.
