Description

Closed negative pressure drainage device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a closed negative pressure drainage device.

Background

In clinic, the incidence of various acute and chronic wounds, ulcers and the like is high, and the diseases are common diseases and frequently encountered diseases. The traditional treatment methods of dressing change and drainage of the wound surface have the problems of easy infection of the wound surface, long period, pain of patients, large workload of medical staff and the like. A negative pressure sealing drainage technology (VSD) is a new wound treatment technology developed in recent years, a polyvinyl alcohol water bloom seaweed salt foam dressing (VSD dressing) with a drainage tube is used for covering or filling a wound surface with skin and soft tissue defects, a biological semipermeable membrane is used for sealing the wound surface to form a closed space, and finally the drainage tube is connected with a negative pressure source to promote wound healing through controllable negative pressure. But the existing closed negative suit consumables are expensive; the specification of the suit foam is single, the sizes of the diabetic foot ulcers are often different, and the size of the diabetic foot ulcers needs to be cut down according to actual needs, so that the foam is wasted; the foam consumable has elasticity, and for foot ulcers with sinus tracts, the foam can not be filled to reach the bottom of the sinus tracts, so that dead space purulence is formed at the blind end of the sinus tracts, and the condition of the foot ulcers is aggravated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a closed negative pressure drainage device to the foam of solving prior art VSD can't be filled and reachs the sinus bottom and lead to the sinus cecum to form the problem of dead space amasss.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a basic technical scheme is: the utility model provides a closed negative pressure drainage device, includes flexible drainage tube, dressing, closed film, drainage bottle, pipe and central negative pressure, the dressing is used for filling the sinus, the one end of flexible drainage tube with the dressing is connected, the other end of flexible drainage tube with the drainage bottle is connected, the drainage bottle with central negative pressure passes through pipe connection, closed film is used for sealing the surface of a wound.

The principle of the basic technical scheme is as follows: the flexible drainage tube penetrates through the wound surface and is inserted into the inner side of the wound to attract effusion, the dressing is wrapped at one end of the flexible drainage tube inserted into the wound, the flexible drainage tube fills the dressing to the bottom of the sinus, the other end of the flexible drainage tube is connected with the drainage bottle, the drainage bottle is communicated with the central negative pressure through the catheter, the central negative pressure provides a negative pressure source for the device, the drainage bottle is used for containing the effusion for drainage, and the sealing film seals the wound surface, so that the window becomes a closed space, the effusion is convenient to drain, and meanwhile, the risk of wound surface infection is reduced.

The beneficial effects of the basic technical scheme are as follows: the dressing can be filled to reach the bottom of the sinus, the problem of dead space purulence formed at the blind end of the sinus is solved, and the whole device is simple in structure and easy to operate.

Preferably, the flexible drainage tube is connected with a drainage joint, and the drainage joint is detachably connected with the flexible drainage tube.

Through the arrangement, the drainage joint is convenient to replace, and effective drainage of accumulated liquid is ensured.

Preferably, the flexible drainage tube is a sputum suction tube.

Through the arrangement, the clinical use is convenient, and the economical efficiency is good.

Preferably, the tube wall of the sputum suction tube is provided with a plurality of drainage holes.

Through the setting, reduce the risk that is blockked up, follow the drainage hole drainage hydrops of each face simultaneously, the drainage is effectual.

Preferably, the dressing is medical gauze.

Through the arrangement, the medical gauze is convenient to use clinically, can be cut according to the size of the foot ulcer, has wide application range, can not cause waste and has good economical efficiency.

Preferably, the sealing film is a surgical film.
