Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a fixing and protecting device for a central venous catheter of an artificial liver. Background Art

[0002] Central venous catheterization in humans is widely used in artificial liver replacement therapy, which has the characteristics of rapid action and large blood flow. However, the immunity of patients undergoing artificial liver replacement therapy is generally low, so the prevention of related complications during the treatment process is very important. Patients with severe liver diseases are prone to catheter-related infections during artificial liver replacement therapy. Due to the poor resistance of patients and skin damage at the catheter puncture site, they are easily invaded by microbial bacteria. If the infection is not treated in time, it is very likely to cause bacteremia and even septicemia, threatening the life of the patient. In addition, complications such as catheter slippage, blood leakage, and catheter blockage are also common during the treatment, which seriously affects the treatment effect and slows down the recovery process. The coagulation mechanism of patients with severe liver diseases is damaged, which is easy to cause hematoma. If the blood leakage is not cleaned up in time, it is easy to breed bacteria and cause infection. The occurrence of catheter-related infections will not only increase the treatment difficulty of patients, but also increase their medical burden.

[0003] Most of the existing central venous catheters are fixed by adhesive stickers. However, when using adhesive stickers for fixation, due to the different wrapping techniques and fixing directions of each staff member, it is not beautiful enough, and the incidence of catheter slippage is relatively high. Patients have a serious psychological burden due to worrying about catheter slippage, which affects their quality of life. Moreover, the input tube and output tube of the central venous catheter are exposed, which is easy to cause infection and trigger other diseases. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a fixing and protecting device for a central venous catheter of an artificial liver.

[0005] The utility model is realized by adopting the following technical scheme: A fixing and protecting device for a central venous catheter of an artificial liver, including an upper shell, the lower end of the upper shell is hinged with a lower shell, a groove is opened inside the lower shell, an adhesive seat is fixedly connected to the inner wall of the groove, a first arc-shaped groove is opened at the right end of the upper shell, a second arc-shaped groove is opened at the right end of the lower shell, rubber pads are fixedly connected to the inner walls of the first arc-shaped groove and the second arc-shaped groove, an input tube is arranged inside the lower shell, an output tube is arranged at the rear end of the input tube, a fixing seat is arranged at the right end of the lower shell, a central venous catheter is fixedly connected inside the fixing seat, a fixing sticker is arranged inside the groove, and an elastic magic sticker is fixedly connected to the bottom of the lower shell.

[0006] Through the above technical solution, the input pipe and the output pipe are protected by the upper shell and the lower shell to avoid being exposed, improving safety. When the upper shell and the lower shell are closed, the surface of the input pipe and the output pipe is extruded by the rubber pad, so that the first arc groove and the second arc groove are sealed, reducing the entry of bacteria into the interior of the upper shell and the lower shell. The inner wall of the fixing sticker contacts the surface of the input pipe and the output pipe, and the other end is adhesively fixed to the bonding seat, improving the fixing effect and preventing the input pipe and the output pipe from slipping.

[0007] As a further improvement of the above solution, the inner wall of the fixing sticker contacts the surface of the input pipe and the output pipe, the bottom of the fixing sticker is adhesively bonded to the surface of the bonding seat, and the fixing sticker has elasticity.

[0008] Through the above technical solution, the elasticity of the fixing sticker enables the fixing sticker to be stretched.

[0009] As a further improvement of the above solution, the right end surface of the input pipe and the output pipe contacts the inner wall of the rubber pad, and the input pipe and the fixed seat penetrate through the fixed seat and are in communication with the central venous catheter.

[0010] As a further improvement of the above solution, the number of the first arc grooves is set to two, and the two first arc grooves are symmetrically distributed with the upper shell as the center. The number of the second arc grooves corresponds to that of the first arc grooves.

[0011] Through the above technical solution, the first arc groove and the second arc groove facilitate the input pipe and the output pipe to enter the interior of the lower shell.

[0012] As a further improvement of the above solution, a fixed block is fixedly connected to the front end of the upper shell. A limiting groove is formed in the inner wall of the fixed block. An installation block is arranged at the lower end of the fixed block. An elastic rope is rotatably connected to the inner wall of the installation block.

[0013] Through the above technical solution, the elastic rope can rotate on the inner wall of the installation block. By pulling the elastic rope and placing it in the groove, the upper shell and the lower shell are fixed.

[0014] As a further improvement of the above solution, the surface of the elastic rope contacts the inner wall of the fixed block, and the rear end of the installation block is fixedly connected to the front end of the lower shell.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The utility model fixes the input pipe and the output pipe by arranging an upper shell and a lower shell. Specifically, the input pipe and the output pipe are placed in the lower shell, and the bottom of the fixing sticker is bonded to the surface of the bonding seat, so that the input pipe and the output pipe are fixed, effectively avoiding the slipping of the input pipe and the output pipe and reducing the psychological burden of the patient. When the upper shell and the lower shell are closed, the rubber pad squeezes the surfaces of the input pipe and the output pipe, making the first arc groove and the second arc groove sealed. The upper shell and the lower shell seal the input pipe and the output pipe, preventing the input pipe and the output pipe from being exposed outside and being easily infected.

[0017] The utility model fixes the upper shell and the lower shell by arranging an elastic rope. Specifically, the direction of the elastic rope is adjusted by rotation, and the elastic rope is pulled into the groove of the fixed block, so as to fix the upper shell and the lower shell, facilitating the operation convenience of fixing between the upper shell and the lower shell.
