Summary of the invention
The purpose of this utility model provide a kind of volume little, in light weight, be easy to carry, energy consumption is low, the convenient use, but satisfy the auxiliary Wound treating instrument apparatus of a kind of assembly portable formula negative pressure of different user and needs of patients.
Separated and overcome the deficiencies in the prior art, technical solution of the present utility model is achieved in that main body controller connects a vacuum suction device, is connected a back-up source or an alternating current power supply transducer respectively on its main body controller and the vacuum suction device.
This utility model compared with prior art, the characteristics of this therapeutic instrument are:
1, therapeutic instrument is combined by main body controller, vacuum suction device, reserve dc source and alternating current power supply transducer four parts, and main body controller and vacuum suction device can be used as the separate unit use after connecing electricity, and each several part is combined into different purposes.Light, be easy to carry, a tractor serves several purposes, can satisfy under the different condition (hospital, family, outdoor or open-air rescue etc.) treatment needs;
2, design electromagnetic valve, vacuum chamber, vacuum pump, hand control switch, the method for taking to control the electromagnetic valve open and close is regulated and control negative pressure value, replaces original control vacuum pump and drives and the rotation speed regulating and controlling circuit; The control of design vacuum chamber forvacuum and hand switch is the control vacuum pump scheme of bleeding manually, has overcome by the control vacuum pump to drive the high problem of energy consumption that the regulation and control negative pressure of bleeding is brought repeatedly.
3, light, economize on electricity is convenient to use under different condition and the environment.Especially adapt to outdoor or open-air power failure rescue of long period and use needs.
The specific embodiment
Accompanying drawing is embodiment of the present utility model.
Below in conjunction with accompanying drawing summary of the invention is described further:
With reference to shown in Figure 1; but a kind of assembly portable formula negative pressure is assisted the Wound treating instrument apparatus; a main body controller A connects a vacuum suction device B; be connected a back-upsource 1 or an alternating currentpower supply transducer 1 respectively on its main body controller A and the vacuum suction device B; described main body controller A connectscentral processing unit 3 bycontrol panel 12;central processing unit 3 connectselectromagnetic valve 8 respectively; audible-visual annunciator 11;electromagnetic valve 8 is connected withdrainage bottle 7 again;drainage bottle 7 is connected withpressure transducer 5;pressure transducer 5 is connected to A/D interface circuit 4; A/D interface circuit 4 andcentral processing unit 3; under-voltage protectingcircuit 2 connects to form main body controller; described vacuum suction device Bdrives vacuum pump 10 byhand switch 13 signals; the negative pressure source thatvacuum pump 10 produces flows intovacuum chamber 9 and forms vacuum suction device; negative pressure source is transported to wound surface C surface by vacuum hose in thedrainage bottle 7; absorption wound surface C superficial cut; make wound obtain convergence as early as possible, reach the purpose of healing.
This utility model has three kinds of usings method:
The hospital ward that 1, the central negative potential source is arranged:electromagnetic valve 8 connects central negative potential source D, and by alternatingcurrent power supply 14 power supplies, main body controller A controls work;
2, use in the hospital of no central negative potential source or the family room:ac power supply 14, external vacuum suction device B, main body controller A controls work;
When 3, having a power failure, outdoor or open-air rescue: reserveDC power supply 1, external vacuum suction device B, main body controller A controls work.
Above-mentioned said main body controller mainly is made up ofcontrol panel 12,central processing unit 3,electromagnetic valve 8,drainage bottle 7,pressure transducer 5, audible-visual annunciator 11 and cabinet.
Said vacuum suction device mainly is made up ofhand switch 13, vacuum table,vacuum chamber 9,vacuum pump 10 and cabinet.
Figure 2 shows that the central processing unit circuit theory diagrams of Fig. 1, among Fig. 2, U9 is a CPU, and U11 is an A/D converter 4, the signal thatpressure transducer 5 is gathered is delivered to U11, converts digital signal to through U11, deliver to U9, after U9 relatively judges,electromagnetic valve 8 work that control is driven by Q3, Q4.U10 is a memory element, preserves the configuration information of all these equipment.J5 is the signal input of oblique pressure pick off 5, in case run-off the straight, the signal of oblique pressure pick off 5 is passed to U9, and U9 just stops the work of this equipment rapidly, guarantees the work safety of this equipment.J7 is a direct current 24V input, and all electric power of this equipment are provided thus.U8 is 7812, produces stable 12V voltage and supplies withelectromagnetic valve 8, and U5 is a 5V DC-DC DC conversion modules, produces stable 5V voltage, supplies with other unit required electric power of this equipment.
Among Fig. 3, K1 is the mode of operation selector switch, and this equipment can be selected two kinds of mode of operations, promptly gives tacit consent to mode of operation and self-defined mode of operation.Self-defined mode of operation can be provided with by K2, K3, K4 combination and finish and preserved by U10 among Fig. 3.U2 is a display driver circuit.The demonstration of duty drives D1 (demonstration charactron) by U2 and shows.L1, L2 are alarm lamp.If any gas leak phenomenon, the L1 alarm lamp is bright in the system.If any the not enough phenomenon of air pressure, the L2 alarm lamp is bright.While openssolenoid valve 8.
After the energized, select mode of operation, this machine mode of operation has two kinds, and the one, default mode, another kind are self-defined patterns.The acquiescence mode of operation is negative pressure 120mmHg, continuous operation 72 hours.Self-defined mode of operation is set as the case may be, at first pushes " set " button and enters the state of setting, sets " negative pressure ", " working time ", " blanking time " three kinds of parameters as required, uses and regulates button setup parameter value.As: set the negative pressure parameter, press " setting " earlier, enter negative pressure by " negative pressure " button again and set, set the negative pressure parameter by adjusting key, the negative pressure value control interval is 10mmHg.Set the back and start central processing system by "start" button, manually openedvacuum pump 10 work (bleeding), or connect central negative potential source D and bleed,central processing unit 3 sends the openelectromagnetic valve 8 of instruction.Whendrainage bottle 7 internal pressures reach the setting negative pressure,pressure transducer 5 issues a signal tocentral processing unit 3, andcentral processing unit 3 sends instruction and cuts outelectromagnetic valve 8;Drainage bottle 7 internal pressures do not reach the setting negative pressure value in the maximum permission time, ordrainage bottle 7 is full, device tilts, orreserve dc source 1 brownout, andcentral processing unit 3 is received and interrupted sending instruction behind the application signal, close thatelectromagnetic valve 8 is concurrently spoken, light is reported to the police.
Before the therapeutic instrument work,drainage bottle 7 one brings out mouth and links to each other with wound surface C by connection tube.
