[0002] Micro-negative pressure absorbent sponge is mainly used in medical institutions, clinical, trauma, chronic wound treatment and other fields.

[0003] Currently, micro-negative pressure absorbent sponges are not easy to apply to the human body surface due to their thick thickness during production. They can only be used to stop bleeding and cannot help wounds heal quickly. They also need to be replaced frequently, which can easily cause secondary injuries.

[0004] Therefore, we propose a micro-negative pressure liquid-absorbing sponge to solve the above problems. Utility Model Content

When the micro-negative pressure liquid-absorbing sponge is used, the pore diameter and soft structure of the sponge are adjusted through air foaming technology, and the sponge is compressed by mechanical processing to form a thin sheet with a compression ratio of 10% for easy application on the human body surface. The sponge forms a porous space after the sponge comes into contact with blood to produce a micro-dynamic negative pressure effect, and the negative pressure promotes the absorption of human blood to accelerate wound healing. Due to the particularity of the material, the number of dressing changes can be reduced and medical labor can be reduced. By reducing the frequency of dressing changes and the material without fiber strain, the secondary injury of the wound can be reduced, the patient's pain can be reduced, and the treatment effect can be improved to solve the problems raised in the above-mentioned background technology.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 A micro-negative pressure liquid-absorbing sponge comprises a liquid-absorbing sponge body 1 and a sterile bag 2; the sterile bag 2 is used to protect the liquid-absorbing sponge body 1, so that the liquid-absorbing sponge body 1 can be stored for a longer time; and the liquid-absorbing sponge body 1 is composed of a plurality of sponge bodies 5. When in use, the liquid-absorbing sponge of a suitable size can be obtained by tearing the sponge at the tearing lines 3 according to the wound of the patient, so that the liquid-absorbing sponge can be more closely fitted to the wound when in use;

[0019] The absorbent cotton body 1 is composed of an upper partition layer 4, a sponge body 5, a lower partition layer 6 and a one-way film 7, and the material does not contain fiber material. When in use, the upper partition layer 4 is adhered to the sponge body 5, and the sponge body 5 can be exposed by gently tearing it, and the lower partition layer 6 is also adhered, but when in use, the lower partition layer 6 is adhered to the sponge body 5 and cooperates with the one-way film 7 to block the blood absorbed by the sponge body 5 to prevent leakage;

[0020] When in use, the pore diameter and soft structure of the sponge body 5 are adjusted through air foaming technology, and it is compressed in conjunction with mechanical processing methods to facilitate application to the human body surface. After the sponge body 5 comes into contact with blood, a porous space is formed to produce a micro-dynamic negative pressure effect; the negative pressure promotes the absorption of human blood and thus accelerates wound healing. Since the sponge body 5 is a PVA porous expanded sponge adjusted by air foaming technology, the frequency of dressing changes can be reduced and the material has no fiber strain, which can reduce secondary damage to the wound, reduce patient pain, and improve the treatment effect.

[0021] The working principle of the utility model is as follows: as shown in the figure, when in use, firstly cut the absorbent cotton of suitable size through the tearing pattern 3, then peel off the upper partition 4, and cover the wound with the sponge body 5, and the sponge body 5 is an air foaming technology to adjust the pore diameter and soft structure of the sponge, and is compressed in cooperation with the mechanical processing method, so as to be conveniently applied to the human body surface, and the sponge body 5 forms a porous space after contacting with the blood to produce a micro-dynamic negative pressure effect; the negative pressure promotes the absorption of human blood and thus accelerates wound healing, because the sponge body 5 is a PVA porous expanded sponge body adjusted by air foaming technology, and in cooperation with the micro-dynamic negative pressure effect, the frequency of dressing changes is reduced and the material has no fiber strain, which can reduce the secondary damage of the wound, reduce the pain of the patient, and improve the treatment effect.
