Detailed description of the invention
Below in conjunction with accompanying drawing (Fig. 1-Fig. 3), the present invention will be described.
Fig. 1 implements the negative pressure therapeutic devices structural representation for the thin-skinned tissue defect disease of cranium jaw of the present invention.Fig. 2 is the structural representation adding controlling organization on Fig. 1 basis.Fig. 3 is the structural representation adding sensor and pressure safety mechanism on Fig. 2 basis.As shown in Figure 1 to Figure 3, for the negative pressure therapeutic devices of the thin-skinned tissue defect disease of cranium jaw, comprise vacuum cup 103, the rim of a cup of described vacuum cup 103 has laminating edge 104, and described laminating edge 104 has the fit surface 110 corresponding to cranium jaw thin-skinned tissue defect site envelope outer ring.Negative pressure generator 101 is connected by pipeline 102 at the bottom of the cup of described vacuum cup 103.Described pipeline 102 is provided with threeway, and described threeway is communicated with control valve 105, negative pressure generator 101 and vacuum cup 103 respectively.Described control valve 105 is electric controlled regulating valve door, and described negative pressure generator 101 is automatically controlled negative pressure generator, and described electric controlled regulating valve door and described automatically controlled negative pressure generator are respectively by circuit 108 connection control mechanism 106.The housing of described vacuum cup 103 is provided with sensor 107, and described sensor 107 connects described controlling organization 106 by holding wire 111.Described sensor 107 comprises baroceptor, temperature sensor and/or humidity sensor.Described sensor 107 adopts optical pickocff.Described negative pressure generator 101 is provided with sensor 107, and described sensor 107 connects described controlling organization 106 by holding wire 111.The housing of described vacuum cup 103 is provided with pressure safety mechanism 109.
Negative pressure generator 101 can be electronic also can be hand-operating vacuum-pump.Negative pressure generator 101 also can directly and vacuum cup 103 be made in one, pipeline 102 can not be used like this.Reduction pressure is opened in the effect of control valve 105, coordinate negative pressure generator to realize the adjustment of pressure when a few thing pattern, if negative pressure generator can produce the negative pressure of needs and carry out on request keeping and regulating, then control valve 105 might not need.Controlling organization 106 can be machinery or electronics, mechanical realize negative pressure simple maintenance or simple pressures cycle change realize therapeutic purposes, pump supporting with it can be then electronic or manual.Electronic type, except can realizing simple control, can also realize more intelligentized work by control circui.Such as timing is carried out to treatment time, automatically change parameter by the course for the treatment of, follow and reach better therapeutic effect according to more sensor parameters to regulate pressure, and recorded data carries out efficacy analysis and improvement for hospital's collection.Sensor 107 according to different control programs can have multiple sensors separately or with the use of, can be baroceptor, temperature sensor, humidity sensor and optical pickocff.Some simple design can not use sensor.Pressure safety mechanism 109 causes negative pressure to cause excessively by force patient injury's evil for preventing controlling organization to lose efficacy, and this design is not required.
As shown in Figure 1, negative pressure generator 101 continuously or interval work, simultaneously control valve 105 is dropped a hint into given pace, makes both reach balance by the flow of control valve charge flow rate or negative pressure generator, thus the air in vacuum cup is maintained in a more stable value.As shown in Figure 2, the control that negative pressure generator 101 accepts controlling organization 106 continuously or interval work, the opening and closing of controlling organization 106 also regulating and controlling valve 105 simultaneously.By the parameter preset, the air in vacuum cup can be made to maintain the value of needs, can programme in controlling organization simultaneously, realize the fluctuation change of negative pressure, realize better therapeutic effect.As shown in Figure 3, the control that negative pressure generator 101 accepts controlling organization 106 continuously or interval work, the opening and closing of controlling organization 106 also regulating and controlling valve 105 simultaneously.By measuring the parameter of the sensor 107 in negative pressure cavity, controlling organization 106 can according to the practical situation in affected part, by the negative pressure adjustment in vacuum cup to being more suitably worth, and can programme and carries out realizing more effective treatment.Improve the injection volume of once performing the operation by the skin in loose affected part, and fall low-fat absorbance by the organizational stress reducing affected part, the number of times of operation can be reduced like this.
In addition; the negative pressure generator of controlling organization adopted likely is interfered or breaks down and makes that negative pressure is excessive causes skin damage; especially skin is weaker sometimes to do the affected part for the treatment of; when adopting fairly simple manual mode to produce negative pressure; because the people applying negative pressure may lack experience to negative pressure; also strong negative pressure may be produced, so the safety device of one or more protection such as pressure safety mechanism 109 is necessary.When gas pressure exceeds safety value, safety device can be put outside air and enter to reduce pressure.When being necessary, the device of closing negative pressure generator can be added.There is sensor, and programmable controller, not only can follow procedure work, the service condition that all right real-time collecting is relevant, and upload data to data center, by data center to after data analysis, determine whether adjust treatment parameter, reach best therapeutic effect.
Herein means bright, more than describe and contribute to those skilled in the art and understand the invention, but and the protection domain of unrestricted the invention.Any enforcement improving the equivalent replacement described above, modification and/or delete numerous conforming to the principle of simplicity and carry out not departing from the invention flesh and blood, all falls into the protection domain of the invention.
