Description
Technical field
The invention belongs to vacuum drawing technique field, relate to a kind of gradual change type vacuum drawing technique, particularly a kind of gradual change type is negativePress sucking method and the therapeutic system based on the method.
Background technology
At present, Medical negative pressure machine is more and more extensive in the application for the treatment of patient wound face, by patient's wound face is carried out to negative pressureAttract, improve the circulation of wound face local blood, improve local metabolic, thereby promote wound repair quality.
The operation principle of vacuum suction therapeutic system is by the device being fitted on patient's wound face is vacuumized, by inciting somebody to actionThe metabolite such as such as the wound fluid sucking-off at wound face place is drained, and promotes local blood circulation, promotes the surface of a wound to repair thereby reachMultiple object.
Mainly there is following problem in the medical negative pressure suction device using at present:
First, from the external American-European developed country that waits, the vacuum suction therapeutic equipment of use be all generally employing lower negative pressure,The working method of the formula of having a rest, there is the problem of atmospheric pressure value cataclysm in negative pressure suction device in the course of the work. Adopt in this way, taking outIn the process of gas and venting, will make in a short period of time the air pressure in device change a lot, for example, take out veryIn empty process, make suddenly the air pressure in device become a negative atmospheric pressure from normal atmosphere (An), in the process of ventingIn, becoming suddenly normal atmosphere (An) from a negative atmospheric pressure again, the pressure of this cataclysm can make patient's wound face produce very strongStrong pain, increase patient's misery.
Secondly, from the at present domestic situation that attracts treatment with Negative pressure machine, be all generally employing high negative pressure, hold, just there is the problem that operating efficiency is lower, cost is higher in the working method of continuous property, and unsuitable height negative in this casePress the pain that also can increase patient's wound face, be unfavorable for that patient recovers.
Affect result for the treatment of thereby continuous negative pressure suction may increase the weight of refractory wounds ischaemic, may cause and be interrupted negative pressureWounds pain is hard to bear, and we study discovery, by improving above method for intermittence, gradual vacuum suction mode can be effectivePromote healing, alleviate patient's pain simultaneously, but there is no the use of this technology and device at present both at home and abroad. Therefore, be badly in need of at presentOne can, in the time attracting treatment, make the slow even variation of negative pressure value in therapeutic system, and have high efficiency, low one-tenthThe vacuum suction therapeutic equipment of this advantage.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of gradual change type vacuum suction method and the therapeutic system based on the method,Can be used for patient's wound face to attract treatment, in the time carrying out the work of extraction gas, the air pressure contacting with wound face can beNow slow even variation, thus the sense of discomfort of patient's wound face is alleviated, effectively promote healing simultaneously.
For achieving the above object, the invention provides following technical scheme:
A kind of gradual change type vacuum suction method, in the method, a vacuum suction cycle comprises 4 stages, is specially: negativePress and attract downward stage T1, negative pressure to keep stage T2, vacuum suction to raise stage T3, zero negative pressure stage T4.
Further, lower stage T1 and described vacuum suction rise stage T3 in described vacuum suction, negative pressure value is evenly slowlyThe mode changing.
The present invention also provides a kind of gradual change type vacuum suction therapeutic system, the mistake that this device comprises liquid collecting tank, is connected with liquid collecting tankFilter screen, four-way connection, relief valve, vavuum pump, air pressure probe, controller, display screen, control panel and computer;
Described liquid collecting tank is connected with the external patient surface of a wound; Screen pack, vavuum pump, relief valve and air pressure probe pass through four-wayJoint is connected; Controller is connected with vavuum pump, air pressure probe and computer respectively;
In the time vacuumizing, relief valve cuts out, and by control panel, computer is arranged, and computer sends instruction to controller, controlDevice processed is controlled the air pressure even variation in liquid collecting tank by controlling vavuum pump rotating speed, and air pressure probe is in liquid collecting tankAir pressure detect in real time, and by air pressure signal feedback to controller, and further feed back to computer and showOn screen, show; The real-time empty atmospheric pressure data analysis that computer docking is received, and according to analysis result, controller is carried outFurther control, so that the vavuum pump of controller control is realized evenly the bleeding of liquid collecting tank, thereby ensure the air pressure in tankPower even variation; The screen pack being connected with liquid collecting tank is for filtering the air extracting from liquid collecting tank; In the time preparing to finish treatment,Open relief valve and keep vavuum pump and air pressure probe work, the air pressure in liquid collecting tank is evenly gone up, untilTreatment finishes.
Further, liquid collecting tank and and its screen pack of being connected between a surge flask is also set, this surge flask is used for compensating liquid collectingThe situation of ullage air-capacitor quantity not sufficient, to make having enough capacity that air extraction is steadily evenly carried out when the extraction gas.
Further, an airstrainer is also set between relief valve and four-way connection, for the air entering from the external world is enteredRow filters.
Further, described relief valve adopts electric-controlled type relief valve.
Beneficial effect of the present invention is: the present invention can be used for patient's wound face to attract treatment, in each treatment cycleIn the extraction gas stage, the air pressure contacting with wound face can present slow even variation, thereby makes patient wound faceSense of discomfort alleviates; Compared with existing equipment, the present invention can reduce patient in the course of the work because of the pressure pain of bringing that die-offsSense, promotes local blood circulation, has low cost, high efficiency advantage.
Brief description of the drawings
In order to make object of the present invention, technical scheme and beneficial effect clearer, the invention provides following accompanying drawing and describe:
Fig. 1 is structural representation of the present invention;
Fig. 2 is duty pressure waveform schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
