Description

Technical Field

[0001] The utility model relates to the technical field of catheter protection, in particular to an improved hemodialysis catheter protection device. Background Art

[0002] Hemodialysis is an important measure for the treatment of acute and chronic renal failure and end-stage renal disease, and the central venous catheter is the "lifeline" for maintaining hemodialysis patients. The central venous catheter can ensure adequate blood flow, is easy to operate, and can be used repeatedly. It is a safe and reliable vascular access. Because the hemodialysis catheter is indwelling for a long time, it is easy to increase the risk of catheter infection. Catheter infection can cause various complications and increase mortality, and increase medical expenses. Therefore, in order to reduce the catheter infection rate, reduce medical expenses, and do a good job of post-catheter maintenance, we follow the blood purification standard operating procedures, implement double dressing changes, select appropriate dressing wrapping methods, and ensure that all nursing staff have unified techniques.

[0003] When medical staff use catheters to perform hemodialysis on patients, they are generally required to use protective covers to protect the surface of the catheters. However, the sizes of catheters vary, so the protective covers cannot be used with catheters of different sizes. At the same time, when the outside of the catheter is hit, the catheter will be squeezed and damaged, which will affect the service life of the device to a certain extent. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0022] Embodiment 1:

[0023] The present application provides an improved hemodialysis catheter protection device, comprising a protection sleeve 1; a protection mechanism 4 is disposed inside the protection sleeve 1;

[0024] The protection mechanism 4 includes a spring 401 and a silicone sleeve 402. The springs 401 are arranged on the surface of the protection sleeve 1 at equal intervals, and the silicone sleeve 402 is fixedly installed on the outer side of the spring 401.

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the protective cover 1 is protecting the surface of the catheter, the spring 401 inside the silicone cover 402 can enable the protective cover 1 to be used with catheters of different sizes, thereby enabling the protective cover 1 to be used with catheters of different sizes, thereby further improving the applicability of the device. At the same time, when the catheter is subjected to external impact, the spring 401 can buffer the external force to prevent the external force from directly acting on the surface of the catheter, thereby protecting the catheter to a certain extent and further improving the service life of the catheter.

[0026] Furthermore, the top of the protective cover 1 is provided with fixing grooves 2 at equal intervals, and the bottom of the protective cover 1 is provided with fixing belts 3 at equal intervals at positions corresponding to the fixing grooves 2, and an electromagnet 301 is fixedly mounted on the surface of the fixing belt 3;

[0027] Specifically, Figure 1 , Figure 2 As shown, when a person places the catheter at the inner center of the protective cover 1, then wraps the fixing belt 3 around the surface of the catheter, and then inserts the fixing belt 3 into the interior of the fixing groove 2, and at the same time energizes the electromagnet 301 through the external control end, the magnetic force generated by the energization of the electromagnet 301 fixes the fixing belt 3 in the inner cavity of the fixing groove 2, thereby protecting the surface of the catheter.

[0028] Further, a placement mechanism 5 is provided on the outside of the silicone sleeve 402, and the placement mechanism 5 includes a placement bag 501, a Velcro 1 502, and a Velcro 2 503. The placement bag 501 is fixedly installed on the inside of the silicone sleeve 402, and the Velcro 1 502 is embedded and installed on the top of the inner cavity of the placement bag 501. The Velcro 1 502 and the surface of the silicone sleeve 402 are fixedly installed with Velcro 2 503;

[0029] Specifically, Figure 1 , Figure 2 As shown, when the protective cover 1 is protecting the surface of the catheter, when the personnel places the disinfection cotton pad for disinfecting the catheter into the interior of the placement bag 501, the disinfection cotton pad can be fixed in the inner cavity of the placement bag 501 through the bonding effect of Velcro 1 502 and Velcro 2 503. Due to the mesh structure of the placement bag 501, the surface of the catheter can be quickly disinfected.

[0030] Working principle: Place the catheter at the central position of the inner side of the protective sleeve 1, then wrap the fixing belt 3 around the surface of the catheter, and then insert the fixing belt 3 into the inside of the fixing groove 2, and at the same time energize the electromagnet 301 through the external control end. The magnetic force generated by the energization of the electromagnet 301 fixes the fixing belt 3 in the inner cavity of the fixing groove 2 to protect the surface of the catheter. When the protective sleeve 1 is protecting the surface of the catheter, the spring 401 inside the silicone sleeve 402 can make the protective sleeve 1 suitable for catheters of different sizes, thereby making the protective sleeve 1 suitable for catheters of different sizes, thereby further improving the applicability of the device. At the same time, when the catheter is subjected to external impact, the spring 401 can buffer the external force to prevent the external force from directly acting on the surface of the catheter, thereby protecting the catheter to a certain extent.

[0031] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
