A polyurethane foam dressing with immobilization function

Abstract

This utility model discloses a polyurethane foam dressing with a fixing function, relating to the field of foam dressing technology. It improves upon the problem of inconvenient fine-tuning of the position of the polyurethane foam dressing during use. The dressing includes two positioning plates, each with a sliding track at its top. By using the positioning plates, the foam dressing body can be initially positioned. The sliding track and slide plate allow for back-and-forth movement of the foam dressing body, enabling fine-tuning of its position. Through holes, limiting rods, limiting holes, and pull blocks provide a fixed limit to the slide plate, further fixing the foam dressing body after adjustment. This allows the foam dressing body to adhere precisely to the wound surface. This method allows for fine-tuning of the foam dressing body's position during adhesion, resulting in precise adhesion and ease of use.

Description

Technical Field

[0001] This utility model relates to the field of foam dressing technology, and in particular to a polyurethane foam dressing with a fixing function. Background Technology

[0002] Polyurethane is a general term for a class of high molecular weight polymers whose main chain contains urethane groups. It is a multi-block copolymer formed by stepwise addition condensation of polyols, polyisocyanates and small molecule chain extenders. Numerous animal experiments and acute and chronic toxicity tests have confirmed that medical polyurethane is non-toxic, non-antigenic, physiologically inert, and has good blood and tissue compatibility. Therefore, it has wide applications in the field of wound dressings. Foam-type medical dressings have a porous structure that is almost completely permeable to oxygen and carbon dioxide and has a strong water absorption capacity. They mainly maintain a moderately moist environment on the wound surface by absorbing exudate and transporting water vapor through the foam structure. They are suitable for wounds with moderate to large amounts of exudate, such as second-degree burns and ulcers. While the polyurethane foam dressings currently in use can meet normal usage requirements, they still have shortcomings in actual use. For example, the current polyurethane foam dressings are not easy to fine-tune in position during use. If the position is not suitable during adhesion, the polyurethane foam dressing needs to be torn open, adjusted, and then re-adheded. This method is prone to tearing the patient's wound during operation, causing discomfort to the patient. Therefore, an improvement is needed. Thus, a polyurethane foam dressing with fixation function is proposed. Utility Model Content

[0027] As a further technical optimization of this utility model, the bottom of the positioning plate 1 is provided with an adhesive layer 13, and the connecting strip 5 is a retractable elastic band.

[0028] In this embodiment: by setting the positioning plate 1, the foam dressing body 2 can be initially limited.

When the position of the foam dressing body 2 deviates and needs to be finely adjusted, the pull block 703 is pulled. The pull block 703 drives the limiting rod 702 to move upward, so that the limiting rod 702 disengages from the limiting hole 704. Then, the slide plate 4 is moved, and the slide plate 4 drives the foam dressing body 2 to move to the precise position. The pull block 703 is released. At this time, the limiting rod 702 is pushed by the action of the compression spring 12. 02. Move the limiting rod 702 into the limiting hole 704 to fix and limit the foam dressing body 2. Finally, rotate the handle 603. The handle 603 drives the screw 602 to rotate. The screw 602 drives the reinforcing plate 604 to move downward. The reinforcing plate 604 reinforces and fixes the corners of the foam dressing body 2, improving the tightness between the foam dressing body 2 and the skin. This prevents the foam dressing body 2 from shifting due to the patient's body movement during use, further improving the effect. This method allows for fine adjustment of the position of the foam dressing body 2 during the adhesion process, ensuring precise adhesion and ease of use.
