Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
Shown in 1 figure, this utility model includes micro computer 1 and compression pump 2, and micro computer 1 and compression pump 2 all are located in the shell 3, micro computer 1 adopts common single-chip microcomputer, compression pump 2 adopts prior art, realizes that by professional compression pump Research Institute it can produce the negative pressure of regulation; The pressure of compression pump 2 is by micro computer 1 control.Compression pump 2 is provided with negative pressure interface 4, be connected with negative pressure pipe 5 on the negative pressure interface 4, the other end of negative pressure pipe 5 is connected on the bottle stopper 9 on the liquid containing bottle 6, also be provided with negative pressure connection tube 7 on the bottle stopper 9, another termination of negative pressure connection tube 7 is a special purpose interface, the vacuum suction pipe 8 that connects the wound location be used to be placed on patient, the length of negative pressure connection tube 7 will be longer than negative pressure pipe 5 and negative pressure connection tube 7 and be stretched into length in the liquid containing bottle 6 and will be longer than negative pressure pipe 5 and stretch into length in the liquid containing bottle 6, and the capacity of liquid containing bottle 6 is about 250-500ml.Negative pressure pipe 5 and negative pressure connection tube 7 are long hard gel body, and the material of vacuum suction pipe 8 is hard gel 16-18 number, and the head end 10cm that is positioned over patient's wound has dense micropore, so that the liquid of sucking-off after irrigating.Be provided with negative pressure display screen 10 and negative pressure by-pass cock 11 in the front of shell 3, they all are connected on the micro computer 1 by circuit.Negative pressure display screen 10 can show the real-time negative pressure size of compression pump 2, undesirablely maybe needs to change negative pressure when size if find them, then regulates by negative pressure by-pass cock 11.Junction at negative pressure interface 4 and negative pressure pipe 5 can be provided with drainage screen 12, is used for preventing that other foreign body from connecing 4 from negative pressure and entering into compression pump 2, influences the running of compression pump 2.Negative pressure interface 4 also is provided with liquid sensor 13 with the junction of negative pressure pipe 5, it is to the sensitive electrical part of current, adopt existing commercially available product, and alarm speaker 14 is set at shell 3 tops, and they are being connected with micro computer 1 circuit, when negative pressure interface 4 places are filled and be back to liquid in the liquid containing bottle 6, alarm speaker 14 sounds the alarm, remind the user of service, and signal is passed to micro computer 1, make it the power supply of automatic cut-out pressure pump 2.For the negative pressure that further guarantees Wound healing and bone regeneration can normally be used, valve 15 also is set on negative pressure pipe 5, can be in the negative pressure that compression pump 2 produces unusual and can't regulate by negative pressure by-pass cock 11 time, the negative pressure of output from negative pressure pipe 5 is regulated, so that whole device is working properly.
This utility model can adopt the AC and DC power supply, and shell 3 can be the rectangle of 20 * 20cm.In use, regulate negative pressure and mode of operation (stopping in 3 minutes 2 minutes), and determine whether to be required pressure, as go beyond the scope, then be adjusted to normal range according to negative pressure display screen 10 data presented as inhaling.Vacuum suction pipe 8 is positioned over patient's wound location, and place aseptic sponge and on aseptic sponge, place the stickiness semipermeable membrane again in wound location, aseptic sponge is adopted the PVA foam of aperture 2-5mm, and adopt different specifications and shape according to actual needs, the stickiness semipermeable membrane uses used clinically general just semipermeable membrane, it has hypoallergenic viscose glue, thin and transparent characteristics, and has the dermatoid moisture-vapor transmission of class, wound anoxia when preventing to operate.Liquid after irrigating drops into the bottom of liquid containing bottle 6 after by vacuum suction pipe 7, and negative pressure pipe 5 is connected on the bottle stopper 9 of liquid containing bottle 6, so flushing liquor can't come out to enter into negative pressure pipe 5 from liquid containing bottle 6.After o'clock can shutting down the flushing liquor of removing in the liquid containing bottle 6, liquid containing bottle 6 hollow amount＜1/2 work on.As do not notice that the flushing liquor in the liquid containing bottle 6 is full when using, and owing to being in the reason negative suction pipe 5 of negative pressure in the negative pressure pipe 5, when flushing liquor arrives liquid sensor 13 places, liquid sensor 13 sends signal and gives micro computer 1, micro computer 1 stops compression pump 2 work, and make alarm speaker 14 send alarm sound, and remind the staff, problem then works on after solving.
