Description

Soluble hemostatic gauze

Technical Field

The utility model relates to the technical field of medical and sanitary articles, in particular to soluble hemostatic gauze.

Background

The skin is an important multifunctional organ of the human body. The skin contacts with the external environment, plays a role of protecting the body, and mainly prevents the loss of moisture, electrolytes and plasma protein, resists the invasion of bacteria, prevents the entry of poisons, resists mechanical damage, prevents the damage of ultraviolet irradiation to the human body and the like. In addition, it has physiological functions of sensation, secretion, excretion and thermoregulation. Therefore, the skin abrasion caused by various traumas and surgical incision should be treated as soon as possible to restore the skin to the tissue and function, and the incision dressing plays an important role in this respect.

An ideal incision dressing should have the following characteristics: 1. covering and protecting the incision; 2. has strong water absorption and can absorb the exudate of the incision; 3. the adhesive is not adhered to the incision, and secondary damage is not caused; 4. the product is soft and comfortable, and can relieve incision pain; 5. can prevent infection of incision.

The incision dressing mainly used in clinic at present is gauze, the raw material source of the dressing is mainly cotton, the dressing only can cover and protect the incision, and the dressing can be adhered to the wound to cause pain and secondary injury during replacement. The non-woven fabric dressing is a substitute of the gauze dressing, but the non-woven fabric dressing has poor water absorption and no antibacterial and analgesic effects. The existing medicine dressing mainly takes a high molecular polyethylene formal porous material as a carrier of an auxiliary material, combines an antibacterial and analgesic medicine in a physical mode, is adhered to the surface of a cut by using an adhesive tape, can absorb the exudate of the cut, and has the effects of sterilizing and relieving pain on the cut by the sustained local release and penetration of the carried medicine. However, the porous polyvinyl formal material easily loses the moisture absorbed by the material after being exposed to the air, so that the porous polyvinyl formal material becomes hard, causing discomfort to patients and even causing secondary damage to wounds.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

A soluble hemostatic gauze is shown in figures 1-3 and comprises an upper substrate 1 and a lower substrate 2, a liquid absorption layer 3 is arranged between the upper substrate 1 and the lower substrate 2, and the liquid absorption layer 3 is adhered to the upper substrate 1 and the lower substrate 2 through a low-sensitivity medical adhesive 4. Wherein the liquid absorbent layer 3 has a size smaller than that of the upper substrate 1 and the lower substrate 2, and the edge of the upper substrate 1 is adhered to the edge of the lower substrate 2.
