Abstract
Disclosed is a disposable negative-pressure drainage band-aid device which relates to the field of medical machinery, in particular to a band-aid device and is structurally characterized in that an operation film is arranged on the periphery of a negative-pressure supporting cover; release paper is attached onto the operation film; a polyurethane sponge is placed inside the negative-pressure supporting cover; one end of a negative-pressure catheter is connected onto the negative-pressure supporting cover; the other end of the catheter is connected with a negative-pressure device; a three-way valve is connected between the negative-pressure catheter and the negative-pressure device; a waste discharge pipe is also connected with the three-way valve; and an one-way valve is clamped on the negative-pressure device through a connection pipe. Leaked liquid from a wound surface can be sucked into the negative-pressure device by pressing the negative pressure device with hands, medicine changing times can be reduced, a wound can be kept moist, and infectious opportunities can be reduced. Simultaneously as a closed sealed supporting cover has certain elasticity and tension, the disposable negative-pressure drainage band-aid device can effectively prevent the wound surface from being strained again, protect the wound, avoid polluting linens and can also be connected with a hospital center negative pressure system. Moreover, the disposable negative-pressure drainage band-aid device avoids back suction by the one-way valve, thereby effectively ensuring safety and effectiveness of therapy.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of wound device that protects.
Background technology
Wound lower negative pressure treatment technology is the new Wound treating technology that development in recent years is got up, show fully that in the clinical practice of hospital it has the new vessels of promotion and enters wound surface, stimulate the plumelet tissue growth, because under sealing lower negative pressure condition, can alleviate and infect the growth that suppresses antibacterial, accelerate the direction that wound healing becomes the dressing development by sufficient drain, but existing negative pressure wound dressing has only single negative pressure source can not adapt to the use of negative pressure system in the hospital, and the expansion that has influenced product is used.
Technology contents
The purpose of this utility model is to provide disposable negative pressure drainage to protect the wound device, can be connected to the central negative pressure system of hospital, itself also has negative pressure source, when faults such as central authorities of hospital negative pressure system generation power failure, the suck-back phenomenon does not take place avoid wound to be polluted.
The technical solution of the utility model is as described below,
A kind of disposable negative pressure drainage protects the wound device, is surgical membrane around the negative pressure support cover, and release paper invests on the surgical membrane, and polyurethane sponge is placed in the negative pressure support cover, and negative pressure catheter one end is connected on the negative pressure support cover, and the other end is connected with negtive-pressure implement.
Be connected with the three-dimensional valve between described negative pressure catheter and the negtive-pressure implement, waste pipe also is connected with the three-dimensional valve.
Pass through connection tube card connection one-way cock on the described negtive-pressure implement.
Described polyurethane sponge is enclosed with anti-adhesive gauze.
Because negative pressure support cover and surgical membrane are formed the space of a sealing; and the edge of support cover contacts with normal skin around the wound face by surgical membrane; negtive-pressure implement itself is exactly a negative pressure source; it is the plastic bottle body of a sealing; in have spring to support; press negtive-pressure implement with hands and promptly produce a vacuum chamber effect; produce a lower negative pressure; connect to make by negative pressure catheter and produce lower negative pressure in the negative pressure support cover simultaneously; can be with negative suction devices such as wound face liquid body exudates; reduce dressing change frequency; keep wound moistening, reduce the chance that infects, sealing is simultaneously supported and is covered with certain elasticity and tension force; can effectively stop pulling again of wound face, protect wound also can not pollute bedding and clothing.Enter negtive-pressure implement when too much in sepage, three-way valve can be opened waste pipe, pushing of handstand negtive-pressure implement makes the sepage dirt discharge by waste pipe.At this moment this utility model another pipeline on negtive-pressure implement just need not be pushed negtive-pressure implement and directly use central negative pressure system by connecting the central negative pressure system that pipe clamp and individual event valve can be connected to hospital.And take place to have a power failure or other faults when closing at central negative pressure system, make the air suck-back easily, this utility model then by one-way cock, has prevented the generation of suck-back phenomenon, thereby guarantees the safety and effectiveness of treatment effectively.
Description of drawings
Fig. 1 is the structural representation that the disposable negative pressure drainage of embodiment 1 protects the wound device.
The specific embodiment:
Embodiment 1:
Disposable negative pressure drainage as Fig. 1 protects the wound device, 1. negative pressure support cover 3. four edges posts surgical membrane, with release paper 2., lay polyurethane sponge 4. in the negative pressure support cover on the surgical membrane, polyurethane sponge is wrapped with anti-adhesive gauze makes it attach the wound face adhesion; Have negative pressure catheter 5. above in the negative pressure support cover, 8. 6. negative pressure catheter connect negtive-pressure implement by three-way valve, and 7. the three-way valve other end is connected with waste pipe; On negtive-pressure implement, be connected with connect pipe clamp 9. with one-way cock 10., constitute a cover closed negative pressure system.
Push negtive-pressure implement make it the compression after, just produce a stable lower negative pressure source, connect to make by pipeline and produced lower negative pressure in the negative pressure support cover simultaneously, reach the effect of absorption sepage, when there is central negative pressure system in hospital, 10. one-way cock is connected with central negative pressure source, at this moment need not push negtive-pressure implement, and directly provide negative pressure by central negative pressure system, this utility model can be used by negtive-pressure implement own or two kinds of methods of central negative pressure system, enlarged the scope of application, thereby effectively prevent the suck-back phenomenon owing to adopted one-way cock to be connected simultaneously, guaranteed the safe and reliable of treatment with central negative pressure system.
