Technical Field

The utility model relates to the technical field of medical auxiliary products, in particular to a sterile pad with high absorption efficiency.

Background Art

As we all know, sterile nursing pads have special functions such as sterility, waterproofness, and impermeability. They are often widely used in hospitals, nursing homes, home care and other places. The pad can effectively prevent stains and pollutants from penetrating into the pad or mattress under the body, ensuring the hygiene and safety of patients or the elderly. At the same time, the pad can also reduce the labor intensity of staff and facilitate the development of nursing work. According to different materials, sterile nursing pads are available in different types such as paper and plastic. In order to ensure the sterility of sterile pads, they are usually disposable and must be replaced in time after use.

The functions of sterile pads currently on the market are relatively simple. The sterile pads currently used in clinical practice are relatively thin and have poor water absorption, and are inefficient in absorbing patients' excrement and blood, making them prone to contamination and infection. In actual use, the sterile pads are prone to wrinkles caused by patient activities, resulting in low absorption efficiency.

(III) Beneficial effects

Compared with the prior art, the utility model provides a sterile pad with high absorption efficiency, which has the following beneficial effects:

The sterile pad with high absorption efficiency has the following steps: firstly, the sterile pad body is placed at the position where absorption is required, and then the adhesive sheets at the bottom ends of the fixing ears on both sides are torn off so that the adhesive layer is in direct contact with the target position. Then, the adhesive layer is fixed at the target position, and the deviation caused by external factors is prevented during actual use for absorption. The sterile pad body is placed flat so that the absorption efficiency of the sterile pad body is better.

DETAILED DESCRIPTION

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.

Please refer to Figures 1-4, a sterile pad with high absorption efficiency, including a sterile pad body 1, an antibacterial structure 2 and a water-absorbing layer 3, the bottom end of the sterile pad body 1 is a waterproof layer 4, the top of the waterproof layer 4 is provided with a lower non-woven fabric layer 5, the upper part of the lower non-woven fabric layer 5 is provided with the water-absorbing layer 3, the top of the water-absorbing layer 3 is provided with an antibacterial structure 2, the upper part of the antibacterial structure 2 is provided with a skin-friendly non-woven fabric layer 6, the skin-friendly non-woven fabric layer 6 is smaller than the sterile pad body 1, the water-absorbing layer 3 The area of the sterile pad body 1 is smaller than that of the sterile pad body 1 and larger than that of the skin-friendly non-woven fabric layer 6. The left and right sides of the sterile pad body 1 are both provided with fixing ears 7. The bottom ends of the two groups of fixing ears 7 and the top end of the right fixing ear 7 are both provided with an adhesive layer 8. An adhesive sheet 9 is provided on the adhesive layer 8. In this embodiment, the sterile pad body 1 is first placed at the position to be absorbed, and then the adhesive sheets 9 at the bottom ends of the fixing ears 7 on both sides are torn off so that the adhesive layer 8 is in direct contact with the target position. Afterwards, the adhesive layer 8 is fixed at the target position to prevent the deviation caused by external factors during actual absorption. The sterile pad body 1 is placed flat to make the absorption efficiency of the sterile pad body 1 better. After adhesion and fixation, it is actually used. The skin-friendly non-woven fabric layer 6 is at the outermost side of the sterile pad body 1, directly contacting the patient's skin, making it more comfortable for the user to use. The liquid enters the antibacterial structure 2 through the skin-friendly non-woven fabric layer 6 to inhibit and deodorize the liquid, and then enters the water-absorbing layer 3, which absorbs the liquid. The water-absorbing layer 3 expands after absorption. Since the skin-friendly non-woven fabric layer 6 is smaller than the sterile pad body 1, the water-absorbing layer 3 after absorption will not leak at the edge of the sterile pad body 1. The waterproof layer 4 prevents the liquid from leaking at the bottom. After use, the left and right ends of the sterile pad body 1 are lifted, and the sticky sheet 9 on the right fixing ear 7 is torn off, so that the adhesive layer 8 is adhered to the top of the left fixing ear 7, which is convenient for later disposal and reduces the occurrence of infection.

In actual use, the absorption efficiency of the water-absorbing layer 3 is further improved. In this embodiment, the material of the water-absorbing layer 3 is a polymer water-absorbing resin. The molecular water-absorbing resin is a reversible adsorption material, mainly composed of polar groups, and has strong hydrophilicity. Due to its three-dimensional network structure, it has a large specific surface area and porosity. The surface area can reach 800-1000m2/g, and the porosity is as high as 80-85%. The polymer water-absorbing resin can expand under the action of water molecules, and the water absorption performance is proportional to the adsorption time. After reaching equilibrium, it can absorb thousands of times its own mass. Under natural conditions, it can repeatedly absorb and release water to maximize the water absorption of the water-absorbing layer 3.

Preferably, in this embodiment, the height of the water absorbing layer 3 is between 0.2 and 0.6 cm. The thickness of the water absorbing layer 3 can be determined according to the occasion of use, thereby being suitable for different use environments.

Preferably, in this embodiment, the antibacterial structure 2 includes an antibacterial layer, and the material of the antibacterial layer is an activated carbon fiber layer. The activated carbon fiber layer has good sterilization and deodorization effects, so as to absorb the odor in the sterile pad body 1.

Preferably, in the present embodiment, the waterproof layer 4 is made of polyurethane material, which has a low water absorption rate and can prevent water vapor from invading, thereby improving the waterproof performance of the sterile pad body 1.

During actual use, the sterile pad body 1 is prone to side leakage after absorption. In order to solve this problem, in this embodiment, the skin-friendly non-woven fabric layer 6 is surrounded by a waterproof layer 4. When the liquid enters the skin-friendly non-woven fabric layer 6 and then enters the water-absorbing layer 3, the water-absorbing layer 3 expands and thickens. Since the skin-friendly non-woven fabric layer 6 is surrounded by the waterproof layer 4, the liquid will be directly locked into the sterile pad body 1 to prevent the sterile pad body 1 from side leakage.

In actual use, in order to increase the absorption speed of the skin-friendly non-woven fabric layer 6 , in this embodiment, a plurality of water absorption holes 10 are evenly arranged on the skin-friendly non-woven fabric layer 6 , and the water absorption holes 10 increase the absorption speed of the skin-friendly non-woven fabric layer 6 .

In actual use, the device is further adapted to different user groups. In this embodiment, the thickness of the sterile pad body 1 is 0.8 to 2 cm, and sterile pad bodies 1 of different thicknesses can be produced according to the actual user groups.

In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved of the present application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
