Description
Technical field
The invention belongs to vacuum drawing technique field, is related to a kind of gradual change type vacuum drawing technique, more particularly to it is a kind of gradually
Variant vacuum suction method and the therapeutic system based on this method.
Background technology
At present, Medical negative pressure machine is more and more extensive in the application in treatment patient trauma face, by entering to patient trauma face
Row vacuum suction, improve wound face local blood circulation, improve local metabolic, so as to promote wound repair quality.
The operation principle of negative pressure attraction treatment device be by the way that the device being fitted on patient trauma face is vacuumized,
Drained by the way that the metabolites such as the wound fluid at wound face are suctioned out, promote local blood circulation, promoted so as to reach
Enter the purpose of wound repair.
The medical negative pressure suction device used at present is primarily present problems with：
First, from the point of view of the developed countries such as external America and Europe, the negative pressure attraction treatment instrument used is typically all the low negative of use
The problem of atmospheric pressure value cataclysm in the course of the work be present in pressure, the working method of batch (-type), negative pressure suction device.Using this side
Formula, during pumping and deflation, the air pressure in device will be made to change a lot in a short period of time, example
Such as during vacuumizing, the air pressure in device is caused to become a negative atmospheric pressure from normal atmosphere (An) suddenly,
During deflation, and normal atmosphere (An) is suddenly become from a negative atmospheric pressure, the pressure of this cataclysm can make the wound of patient
Hinder face and produce very strong pain, increase the pain of patient.
Secondly, from the point of view of attract the situation for the treatment of using Negative pressure machine from the current country, the height typically used is born
Pressure, the working method of continuation, there is the problem of operating efficiency is relatively low, cost is higher in this case, and inappropriate
High negative pressure can also increase the pain in patient trauma face, be unfavorable for patient's recovery.
Continuous negative pressure suction may aggravate refractory wounds ischaemic so as to influence therapeutic effect, and be interrupted negative pressure can
Wounds pain can be caused hard to bear, we have discovered that, by improving above method as interval, gradual vacuum suction mode energy
Healing is enough effectively facilitated, while mitigates patient pain's sense, but there is no the use of the technology and device both at home and abroad at present.Therefore, mesh
Preceding urgent need one kind can be when attract treatment so that the slow even variation of negative pressure value in therapeutic system, and with efficient
The negative pressure attraction treatment instrument of rate, low-cost advantage.
The content of the invention
In view of this, the treatment it is an object of the invention to provide a kind of gradual change type vacuum suction method and based on this method
Device, attraction treatment is carried out available for patient trauma face, when carrying out taking out deflation operations, the air pressure that is contacted with wound face
Slow even variation can be presented, so that the sense of discomfort in patient trauma face mitigates, while effectively facilitate healing.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of gradual change type vacuum suction method, in the method, a vacuum suction cycle include 4 stages, are specially：
Stage T1 is lowered in vacuum suction, negative pressure is kept for stage T2, stage T3, zero negative pressure stage T4 are raised in vacuum suction.
Further, stage T1 and vacuum suction up-regulation stage T3 are lowered in the vacuum suction, negative pressure value is uniform
Slowly varying mode.
Present invention also offers a kind of gradual change type negative pressure attraction treatment device, the device include liquid collecting tank, with liquid collecting tank phase
Screen pack, four-way connection, relief valve, vavuum pump, air pressure probe, controller, display screen, control panel and electricity even
Brain；
The 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-way connection is connected；Controller is connected with vavuum pump, air pressure probe and computer respectively；
When vacuumizing, relief valve is closed, and computer is configured by control panel, computer sends finger to controller
Order, controller control the air pressure even variation in liquid collecting tank, air pressure probe pair by controlling vacuum revolution speed
Air pressure in liquid collecting tank is detected in real time, and air pressure signal is fed back into controller, and further feeds back to electricity
Brain is simultaneously shown on a display screen；The real-time air pressure data that computer docking receives are analyzed, and according to analysis result
Controller is further controlled, to cause uniform pumping of the vavuum pump realization that controller controls to liquid collecting tank, so as to protect
Demonstrate,prove the air pressure even variation in tank；The screen pack being connected with liquid collecting tank is used to filter the air extracted from liquid collecting tank；When
When preparing to terminate treatment, open relief valve and keep vavuum pump and air pressure probe to work so that the air in liquid collecting tank
Pressure is uniformly gone up, until treatment end.
Further, a surge flask is also set up between liquid collecting tank and the screen pack being connected with it, the surge flask is used to mend
The situation of liquid collecting tank air containment deficiency is repaid, there are enough capacity in extraction gas so that air extraction even enters
OK.
Further, an airstrainer is also set up between relief valve and four-way connection, for from the external world enter
Air is filtered.
Further, the relief valve uses electric-controlled type relief valve.
The beneficial effects of the present invention are：The present invention can be used for carrying out attraction treatment to patient trauma face, be controlled at each
Treat in the cycle and take out releasing phase, slow even variation can be presented in the air pressure contacted with wound face, so that patient
The sense of discomfort of wound face mitigates；Compared with existing equipment, the present invention can reduce patient because pressure die-offs in the course of the work
The pain brought, promote local blood circulation, there is inexpensive, efficient advantage.
