Description

Antibacterial wound negative pressure drainage gauze set

Technical Field

The utility model relates to the technical field of drainage medical instruments, in particular to an antibacterial negative pressure wound drainage gauze set.

Background

The negative pressure closed drainage can remove the exudates and necrotic tissues on the wound surface in time, ensure the cleanness of the wound surface, isolate external bacteria and foreign matters, facilitate the healing of the wound surface, and is more and more concerned by the medical field due to good curative effect. But current negative pressure seals drainage equipment is expensive, and one set of negative pressure drainage dressing is up to five thousand yuan, brings heavy economic burden for the patient, and current negative pressure drainage dressing generally uses 7 ~ 10 days, need wash back used repeatedly, and bactericidal performance is poor, and to the wound that is difficult to heal, because the treatment cycle is more than 10 days far away, one set of dressing can't satisfy the nursing demand, and repeated purchase can bring heavy economic burden for the patient.

In addition, the existing negative pressure drainage dressing is generally gauze which is directly contacted with the wound, the gauze is easily adhered to the wound in the contact process, and the wound can be torn when the drainage is finished and the dressing is removed, so that secondary injury is caused to a patient.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model aims to provide an antibacterial wound negative pressure drainage gauze set.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

an antibacterial wound negative pressure drainage gauze suit comprises a polyester gauze layer, wherein a transparent dressing pad is arranged above the polyester gauze layer, a drainage hole is formed in the transparent dressing pad, a silica gel pad is connected above the transparent dressing pad through self-adhesive silica gel, a second through hole is formed in the silica gel pad, a silica gel drainage tube is arranged in the second through hole, and the silica gel drainage tube (8) is tightly attached to the side wall of the second through hole;

the polyester gauze layer is uniformly coated with soft silica gel, and the soft silica gel covers 50-70% of the aperture of the gauze.

Further, a first through hole is formed in the self-adhesive silicone gel, and the diameter of the first through hole is larger than that of the second through hole, so that an annular groove is formed among the self-adhesive silicone gel, the silicone pad and the transparent dressing film; the connecting piece is set up to silica gel drainage tube bottom, and silica gel drainage tube and connecting piece are the right angle, and the connecting piece can rotate at the ring channel, adjusts the direction of silica gel drainage tube.

Preferably, in the ring channel, the bottom of silica gel pad sets up the paster, and transparent dressing pad top sets up down the paster, and the connecting piece is located the paster and the clearance of paster down.

Preferably, the soft silica gel contains silver sulfadiazine.

Compared with the prior art, the utility model has the following advantages:

according to the antibacterial wound negative pressure drainage gauze set, the polyester gauze layer is uniformly coated with soft silica gel, the soft silica gel contains sulfadiazine silver, and the soft silica gel covers 50-70% of the pore diameter of the gauze, so that during drainage, the gauze set can well drain and can buffer the compression of dressing on a wound surface under negative pressure; when the gauze is replaced after drainage is finished, the soft silica gel can prevent the polyester gauze from being well separated from the wound surface, the polyester gauze cannot be adhered to the wound surface, secondary wound of the wound is avoided, and meanwhile, the sulfadiazine silver can sterilize the wound and prevent wound infection;

the direction to the silica gel drainage tube is adjusted and is injectd, satisfies the requirement of different patients to the drainage direction, also can avoid the patient at long-time drainage in-process health must keep a posture simultaneously, and the body posture adjustment can not lead to the fact the influence to the drainage process.

Detailed Description

The utility model is further described with reference to specific examples.

Example 1

An antibacterial wound negative pressure drainage gauze set comprises a polyester gauze layer 1, a transparent dressing film 2 is arranged above the polyester gauze layer 1, a drainage hole 3 is formed in the transparent dressing film 2, a silica gel pad 5 is connected above the transparent dressing film 2 through a self-adhesive silica gel 7, a second through hole 6 is formed in the silica gel pad 5, a silica gel drainage tube 8 is installed in the second through hole 6, and the silica gel drainage tube 8 is tightly attached to the side wall of the second through hole 6;

soft silica gel is uniformly coated on the polyester gauze layer 1, covers 50-70% of the pore diameter of the gauze, and can be used for drainage well and buffering the compression of the dressing on a wound surface under negative pressure during drainage; when the gauze is replaced after drainage is finished, the soft silica gel can prevent the polyester gauze from being separated from the wound surface well, the polyester gauze cannot be adhered to the wound surface, and secondary wound of the wound is avoided.
