Description

Waterproof breathable anti-infection vaccine needle eye protection hydrocolloid dressing

Technical Field

The utility model relates to the technical field of medical dressing, in particular to a waterproof breathable anti-infection vaccine needle eye protection hydrocolloid dressing.

Background

Medical dressings are an important class of medical articles. The medical dressing is often applied to the wound of a patient in the treatment processes of operation, dressing change and the like, plays roles in stopping bleeding and protecting the wound, and enables the wound to heal quickly. Specifically, the medical dressing covers the wound surface of the injured skin, so that the medical dressing provides an advantageous microenvironment for wound healing before the skin is rebuilt or recovered, the wound surface is isolated from the outside on one hand, the wound surface is protected, the dressing has liquid absorbing capacity on the other hand, liquid exuded from the wound surface can be absorbed, and various problems caused by exuded liquid are prevented.

Existing vaccines, particularly the new crown vaccines, are typically injected intramuscularly, leaving behind the needle eye. After vaccine injection, a medical cotton ball is generally adopted to press at the needle eye for hemostasis, medical staff or an injector is required to press, the operation is troublesome, and if the pressing force is too small, the needle eye is easy to continuously bleed. A hemostatic dressing of application number CN201721797935.2 has been used to provide hemostatic procedures for needle eye wounds, but the dressing does not have the effect of accelerating wound repair.

Hydrocolloid dressing is a dressing made by mixing elastic polymeric hydrogel with synthetic rubber and adhesive. The hydrocolloid dressing has the characteristic of absorbing wound surface seepage, and can form a closed wet environment around the wound after absorbing seepage, so that the capillary proliferation and the formation of granulation tissues can be promoted, and the healing of the wound surface is accelerated; in addition, the hydrocolloid dressing also has the function of debridement. Currently, a wide variety of hydrocolloid dressings have been used for the management and care of wounds.

The hydrocolloid dressing of the prior application number CN201720930487.2 comprises a main body, more than two tentacle-shaped extension parts are uniformly distributed on the outer edge of the main body, the main body and the extension parts comprise an isolation layer and a hydrocolloid adhesive layer, a layer of PU film is compounded on the hydrocolloid adhesive layer, and the more than two extension parts are radially arranged, can be better adhered to joints and uneven wounds, and prevent warping and even falling; however, the technology does not have the functions of waterproof, ventilation and infection prevention, and is easy to cause bacterial growth, and the recovery of needle eye wounds and the physical health of an injected person are affected.

Therefore, how to provide a hydrocolloid dressing with waterproof, breathable and anti-infection functions and capable of reducing bacteria breeding is a technical problem to be solved by the person skilled in the art.
