Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical sheaths, in particular to a sterile isolation protective sheath for medical cables. Background Art
[0002] With the development of technology, some medical instruments need to be connected to corresponding wires to work together. How to effectively put sterile protective covers on the wires and connect them to sterile instruments to ensure the safe and smooth development of medical treatment has become one of the important links in the preparation of surgical instruments.
[0003] Medical cable sterile isolation protective covers (also called arthroscopic covers) are mostly disposable sterile straight-tube sterile covers, usually made of polymer film. The arthroscopic covers currently in use are about 2 meters long. After being taken out, the arthroscopic cover needs to be fully propped up to ensure that the cable can be inserted. During the propping up of the arthroscopic cover, the chance of contamination increases, thereby increasing safety hazards. Utility Model Content
[0004] In view of the shortcomings of the prior art, the utility model provides a sterile isolation protective cover for medical cables. The specific technical solution is as follows:
[0005] A medical cable sterile isolation protective cover comprises a protective cover body, wherein the protective cover body is a straight tube structure with openings at both ends, a plurality of airways with spiral structures are distributed in an annular shape on the wall of the protective cover body, a diverter cavity 1 with an annular structure is provided on the outer wall at the entry port of the protective cover body, and a diverter cavity 2 with an annular structure is provided on the outer wall at the insertion port of the protective cover body, the two ends of the airway are respectively connected with corresponding positions of the diverter cavity 1 and the diverter cavity 2, the diverter cavity 1 has an air inlet port, and the diverter cavity 2 has an air outlet port.
[0006] As an improvement of the above technical solution, the air channels are located on the outer surface of the protective sleeve body and are evenly distributed.
[0007] As an improvement of the above technical solution, the air channels are located on the inner surface of the protective sleeve body and are evenly distributed.
[0008] As an improvement of the above technical solution, the air duct is fixedly connected to the wall of the protective sleeve body, and a limiting reinforcing rib is formed at the connection.
[0009] As an improvement of the above technical solution, the end sides of the diversion chamber 1 and the diversion chamber 2 are both provided with guide sleeves of annular structure, and the guide sleeves are arranged on the restraining belt, and the two ends of the restraining belt extend out of the corresponding ends of the guide sleeves.
[0010] Beneficial effects of the utility model:
[0011] 1. Since the expansion process of the protective cover body does not touch the inside of the protective cover body, the possibility of cross contamination is extremely small. The inflated airway forms a protective layer on the outer wall of the protective cover body, and prevents the protective cover body from being damaged in the first place, thereby improving the safety of use. When leakage is found in the airway, diversion chamber 1 and diversion chamber 2 during use, it can be detected that the protective cover body may be damaged.
[0012] 2. When the airway is located inside the protective cover body, it can form an isolation layer after inflation to prevent the cable from directly contacting the protective cover body. In addition, the airway is a spiral structure, and the cable can also be more easily screwed into and passed through the protective cover body along the spiral structure of the airway.
[0013] 3. Since the airway is fixedly connected to the outer wall of the protective cover body, the connection method can be welding or sewing, and a limit reinforcement rib will be formed at the connection. The limit reinforcement rib is used to limit the protective cover body during the inflation of the airway to prevent the over-inflated airway from causing deformation of the protective cover body or tearing the wall of the protective cover body.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0019] like Figure 1-3The utility model provides a technical solution: a medical cable sterile isolation protective cover, including a protective cover body 10, the protective cover body 10 is a straight tube structure with openings at both ends, a plurality of spiral-structured airways 20 are distributed in an annular shape on the wall of the protective cover body 10, a diverter cavity 1 40 with an annular structure is provided on the outer wall at the entrance port 30 of the protective cover body 10, a diverter cavity 2 60 with an annular structure is provided on the outer wall at the insertion port 50 of the protective cover body 10, two ends of the airway 20 are respectively connected with corresponding positions of the diverter cavity 1 40 and the diverter cavity 2 60, the diverter cavity 1 40 has an air inlet port 70, and the diverter cavity 2 60 has an air outlet port 80.
[0020] Specifically, the protective cover body 10 described in this solution is a disposable plastic film protective cover commonly found on the market. When in use, it is taken out from the sterile package. At this time, the protective cover body 10 is in a storage state, and it is in a long strip shape after unfolding. When it is needed, gas is injected into the airway 20 through the air inlet port 70. The gas is first introduced into the airway 20 evenly through the diversion cavity 1 40. At this time, the air outlet port 80 is sealed. As the air pressure in the airway 20 increases, the protective cover body 10 will gradually expand, and finally form a straight tube structure, at which time the cable can be isolated.
[0021] Since the expansion process of the protective cover body 10 does not touch the inside of the protective cover body 10, the possibility of cross contamination is extremely small. In addition, the inflated airway 20 forms a protective layer on the outer wall of the protective cover body 10, and prevents the protective cover body 10 from being damaged in the first place, thereby improving the safety of use. When the airway 20, the diverter cavity 1 40 and the diverter cavity 2 60 are found to have air leakage during use, it can be detected that the protective cover body 10 may be damaged.
[0022] In one embodiment, the air passages 20 are located on the outer surface of the protective cover body 10 and are evenly distributed. The air passages 20 are distributed on the outer surface of the protective cover body 10, so that a protective layer can be provided on the outer surface of the protective cover body 10. The object will first contact the air passages 20 and can contact the protective cover body 10 only after breaking through the air passages 20.
[0023] In one embodiment, the air passage 20 is located on the inner surface of the protective cover body 10 and is evenly distributed. Since the cable needs to pass through the protective cover body 10, the end of the cable is very likely to puncture or scratch the protective cover body 10 during the process of passing through the protective cover body 10. When the air passage 20 is located inside the protective cover body 10 and can form an isolation layer after inflation, the cable is prevented from directly contacting the protective cover body 10. In addition, the air passage 20 is a spiral structure, and the cable can also be more easily screwed into and passed through the protective cover body 10 along the spiral structure of the air passage 20.
[0024] In one embodiment, the air duct 20 is fixedly connected to the wall of the protective cover body 10, and a limiting reinforcement rib 90 is formed at the connection. The air duct 20 is fixedly connected to the outer wall of the protective cover body 10, and the connection method can be welding or sewing, and a limiting reinforcement rib 90 is formed at the connection. The limiting reinforcement rib 90 limits the protective cover body 10 when the air duct 20 is inflated, so as to prevent the over-inflated air duct 20 from causing the protective cover body 10 to be non-deformable or tearing the wall of the protective cover body 10.
[0025] In one embodiment, the end sides of the diverter chamber 1 40 and the diverter chamber 2 60 are provided with a guide sleeve 100 of an annular structure, and the guide sleeve 100 is sleeved on the restraining belt 110, and the two ends of the restraining belt 110 extend out of the corresponding ends of the guide sleeve 100. Specifically, the guide sleeve 100 located at the end sides of the diverter chamber 1 40 and the diverter chamber 2 60 can be one, or two symmetrically arranged. When there is one guide sleeve 100 located at the end sides of the diverter chamber 1 40 and the diverter chamber 2 60, the central angle corresponding to the guide sleeve 100 is close to 360°, and at this time, a total of two restraining belts 110 are required. When there are two guide sleeves 100 located at the end sides of the diverter chamber 1 40 and the diverter chamber 2 60, the central angle corresponding to each guide sleeve 100 is close to 180°.
[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
