[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0023] like Figures 1 to 6 As shown, a medical sterile protective sleeve includes a protective sleeve 4, an mounting sleeve 5 for fixing the sterile protective sleeve is connected to the protective sleeve 4, the bottom of the protective sleeve 4 is tightly fitted with a wound cleaning cart table 1, the wound cleaning cart table 1 is provided with a table edge 3, the mounting sleeve 5 is movably fitted onto the table edge 3, the wound cleaning cart table 1 has a drain port 2, the protective sleeve 4 is connected to an outlet 7, and the outlet 7 has a filter mesh-like distribution at its port, which can separate gauze and brush, making it easy to remove the brush later. The outlet 7 is installed in the drain port 2, and mounting pads 8 are attached to the four corners of the table edge to protect the sterile protective sleeve and prevent the sterile protective sleeve from sliding. The mounting pads 8 are pasted inside the mounting sleeve 5. In this setup, the protective sleeve 4 covers the cleaning cart platform 1, preventing blood, body fluids, and other contaminants from directly contacting the equipment. The mounting sleeve 5 secures the protective sleeve 4 by connecting to the platform edge 3, ensuring its stable coverage of the platform. The platform edge 3 provides the connection support point for the mounting sleeve 5, defining the coverage area of the protective sleeve 4. The drain outlet 2 centrally discharges liquid waste, connecting to the outlet 7 to form a guide channel. The outlet 7 guides the waste collected by the protective sleeve 4 into the drain outlet 2, preventing liquid stagnation. The mounting pad 8 is pasted inside the mounting sleeve 5, buffering the wear of the sterile protective sleeve on the edges of the platform edge and enhancing anti-slip properties. The outlet of the protective sleeve 4 is 10cm longer than the outlet of the cleaning cart, effectively preventing waste liquid from contaminating the cleaning cart's drain outlet due to the equal-length protective sleeves.
[0024] like Figures 1 to 6 As shown, in a specific embodiment, the protective sleeve 4 is funnel-shaped and fits tightly against the surface 1 of the cleaning cart. The protective sleeve 4 is made of transparent polyethylene film. In this configuration, the funnel-shaped design guides the liquid to converge towards the drain outlet 2, improving the diversion efficiency. The polyethylene film material has flexibility and transparency, fits the surface well, and facilitates observation of the contamination status.
[0025] like Figures 1 to 6 As shown, furthermore, the edge of the mounting sleeve 5 is provided with an elastic band 6, which is distributed circumferentially along the mounting sleeve 5 to enhance the tightness of the fit between the mounting sleeve 5 and the table edge 3. In this configuration, the elastic band 6 is distributed circumferentially along the mounting sleeve 5, and the elastic contraction force enhances the tightness of the fit with the table edge 3, preventing the aseptic protective sleeve from shifting.
[0026] like Figures 1 to 6As shown, the mounting pad 8 is made of non-woven fabric. The surface of the non-woven fabric is embossed to form an anti-slip texture, and the mounting pad 8 is 1-3mm thick. It is used to buffer the wear and tear on the protective sleeve from the edges and corners of the buffer platform, while the softness of the non-woven fabric enhances the fit with the mounting sleeve 5. In this design, the non-woven fabric is soft and inexpensive, it buffers the mechanical damage to the protective sleeve from the edges and corners of the buffer platform, the embossed anti-slip texture increases friction to prevent the protective sleeve from slipping, and the 1-3mm thickness balances buffering performance and ease of use, making it suitable for disposable applications.
[0027] like Figures 1 to 6 As shown, the protective sleeve 4, mounting sleeve 5, and outlet 7 are integrated thermoformed structures, forming a sealed protective system that prevents blood, bodily fluids, and disinfectants from corroding the surface of the wound cleaning cart. In this setup, the integrated thermoformed structure eliminates seams, creating a sealed protective system that prevents contaminants from penetrating to the equipment surface.
[0028] like Figures 1 to 6 As shown, the inner wall of the outlet 7 is provided with an anti-stick coating to reduce the adhesion of contaminants and ensure rapid liquid discharge. In this configuration, the anti-stick coating reduces the adhesion of blood, bodily fluids, and other contaminants, ensuring rapid liquid discharge and reducing the risk of residue.
[0029] The implementation principle of a medical sterile protective sleeve in this embodiment is as follows: The medical sterile protective sleeve uses the elastic contraction force of the elastic band 6 to quickly attach the mounting sleeve 5 to the outer edge of the cleaning cart table 3. The non-woven fabric mounting pad 8 in the mounting sleeve 5 adopts an embossed anti-slip design, which not only increases friction but also prevents the sterile protective sleeve from being damaged due to friction. The funnel-shaped protective sleeve 4 uses polyethylene film as the base material, utilizing its flexibility to tightly adhere to the table surface, forming a guide surface that slopes from the outside inwards, in conjunction with the Teflon anti-stick coating on the inner wall of the discharge port 7. The layer allows blood, bodily fluids, and other liquids to quickly converge towards the drain outlet 2 under gravity. The sterile protective sleeve is made using a seamless hot-pressing process, fusing the installation sleeve 5, protective sleeve 4, and drain outlet 7 into one unit to ensure overall sealing. The transparent material design allows medical staff to observe the contamination status of the work surface in real time, facilitating timely replacement. After use, it can be quickly disassembled along the elastic band 6. The sterile protective sleeve and waste are packaged together for disposal, eliminating the need for traditional cleaning procedures, complying with medical infection control standards, and significantly reducing the risk of cross-infection and equipment maintenance costs.
