Description

Technical Field

[0001] This utility model relates to the field of medical degreased cotton processing technology, specifically a medical degreased cotton forming and dehydration device. Background Technology

[0002] Medical absorbent cotton is a common medical device used for infusion, care, and protection during medical treatment and surgical procedures. It absorbs fluids, prevents infection, and protects wounds. Medical absorbent cotton is typically made of pure cotton, free of any chemical additives, ensuring product safety and hygiene. It is soft, highly absorbent, and breathable, effectively absorbing and retaining liquids to prevent leakage and contamination.

[0003] Publication number CN212764916U discloses a medical absorbent cotton forming and dehydration device, which includes a dehydration cylinder, a motor, a pushing mechanism and a drag-reducing plate. A forming cavity is set inside the hollow dehydration cylinder, and a pushing mechanism is set at the top of the dehydration cylinder. The pushing head of the pushing mechanism penetrates into the forming cavity. The motor is connected to the dehydration cylinder and drives it to rotate. The drag-reducing plate supports the bottom of the dehydration cylinder and reduces frictional resistance. The pushing mechanism drives the pushing head to penetrate into the dehydration cylinder to dehydrate the absorbent cotton. The dehydrated cotton is formed in the forming cavity. This invention overcomes the problems of inconsistent specifications, easy splashing, and difficulty in storage and measurement of the original medical cotton dehydration molding process. It features a simple structure, uniform cotton shape and specifications, which is conducive to measurement and molding. The cotton is less likely to splash and be lost during extrusion, and the operation is simple and convenient. However, the area of ​​the extrusion head is too small to cover the dehydration cylinder. The splashed cotton will adhere to the upper surface of the extrusion head, causing cotton loss and making it difficult to clean. In addition, the dehydration cylinder, inner cylinder and fixed shaft are integrally formed, which is relatively complex in shape and more troublesome to process. Therefore, we propose a medical degreased cotton molding and dehydration device. Utility Model Content
