Description

Negative pressure drainage device

technical field

The utility model relates to the technical field of medical devices, in particular to a drainage device for suctioning and sucking out wound secretions and exudates of patients through negative pressure sealing, especially for sucking the venom accumulated in local tissues of snakebite patients.

Background technique

The traditional negative pressure sealing drainage technique refers to covering or filling the wound surface of skin and soft tissue defects with a medical foam dressing composed of polyvinyl alcohol foam material and multi-side hole rigid drainage catheter, and then using a semipermeable adhesive film to heal the wound surface. Closed, continuous negative pressure to attract wound exudate, a new treatment method to control wound infection and promote wound healing. At present, most of the negative pressure sealing drainage devices used in clinical use are imported VSDs, which are composed of medical sponge foam dressings, built-in hard drainage catheters, and semi-permeable adhesive films; this kind of drainage device is expensive and increases the treatment cost of patients. Clinical application is limited. On the other hand, the size of the sponge foam dressing area of this kind of drainage device is relatively fixed, and the area of absorbing exudate is relatively constant, especially when absorbing irregular wounds caused by poisonous snake bites, the adsorption area cannot be determined according to the size of the wound. Trade-offs, sometimes easy to cause blockage of the drainage tube.

Utility model content

The technical problem to be solved by the utility model is to provide a negative pressure drainage device, which can solve the problems that the use of an imported drainage device is expensive, increases the treatment cost of patients, and the area of the drainage device absorbs seepage is fixed in size, and the drainage tube is easy to block.

In order to solve the above problems, the technical solution of the utility model is: this negative pressure drainage device includes a suction tube whose rear end is connected to a negative pressure source, and the front end of the suction tube is buried between the upper and lower layers of cotton cloth, and the upper layer of the cotton cloth A sterile transparent film covering layer is arranged on the layer, and a plurality of side holes are opened at the front end of the suction tube.

In the above technical solution, a more specific solution may also be: the front end of the suction tube is stitched and fixed between the upper and lower layers of the cotton cloth layer with medical suture; the cotton cloth layer is a medical sterile cotton pad; The suction tube is a sterile suction tube.

Further: there may be multiple suction pipes whose front ends are embedded between the upper and lower layers of cotton cloth.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following beneficial effects:

1. The utility model can continuously absorb snake venom, secretions and exudates on the wound surface through the side hole of the suction tube in the cotton cloth layer, reduce the probability of wound infection, and effectively promote wound healing; the utility model has a simple structure and is easy to assemble. Clinically, conventional medical instruments can be directly used according to the shape or area of the wound. For example, a sterile suction tube head is used to cut out a side hole and then used as a suction tube. The cotton layer is a medical sterile cotton pad, which can be cut to an appropriate size, and then used Medical sutures can be used to sew and fix the suction tube, and the cost is low, but the clinical effect is very good, shortening the hospitalization time of patients, and saving a lot of money for patients.

2. Compared with the imported drainage device VSD, this utility model has the advantages of flexible and diverse combinations, adjustable adsorption seepage area, and is not easy to block the tube. One or two cotton pads with different areas can be used to stitch one or two according to the actual situation. If the wound needs to be kept dry and the suction is continuous, one suction tube can be used to prevent wound infection; for snakebite patients with irregular and irregular wounds, two or more suction tubes can be used; for other For drainage, one of them can also be used as a suction tube, and the other can be used as a flushing tube, which can effectively prevent the wound secretion from clogging the tube.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment 1: The negative pressure drainage device of Fig. 1 and Fig. 2 comprises a suction tube 3, and the rear end of suction tube 3 is used to connect negative pressure source during use, and negative pressure source is connected hospital negative pressure center clinically in hospital The conventional wall negative pressure suction device can be connected to a negative pressure machine during first aid or treatment outside the hospital; the front end of the suction tube 3 is buried between the upper and lower cotton cloth layers 1, and the upper cotton cloth layer 1 is provided with a sterile transparent film covering layer 4. The front end of the suction tube 3 is provided with a plurality of side holes 2; the front end of the suction tube 3 is stitched and fixed between the upper and lower cotton layers 1 with medical sutures 5; the cotton layer 1 is a medical sterile cotton pad; the suction tube 3 is made of Sterile suction tube.

Embodiment 2: the negative pressure drainage device of Fig. 3 comprises two suction tubes 3, and the front ends of the suction tubes 3 are embedded between the upper and lower cotton cloth layers 1, and the upper cotton cloth layer 1 is provided with a sterile transparent film covering layer 4, The front end of the suction tube 3 is provided with a plurality of side holes 2; the front end of the suction tube 3 is stitched and fixed between the upper and lower cotton layers 1 with a medical suture 5; the cotton layer 1 is a medical sterile cotton pad; the suction tube 3 is made of sterile Suction tube.
