Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hemodialysis tubes, in particular to a temporary hemodialysis neck tube protection and fixing cap. Background Technique
[0002] The central venous catheter for hemodialysis is one of the vascular accesses for hemodialysis and other blood purification therapies. Its principle is to insert a double-lumen catheter into the central vein. One lumen of the double-lumen catheter is used as the arterial lumen for drawing out blood, and the other lumen is used as the venous lumen for transfusing the purified blood back into the patient's body. The insertion site of the catheter is generally the bilateral internal jugular veins, bilateral subclavian veins, and bilateral femoral veins, with the right internal jugular vein being the first choice and the most commonly used catheterization site in clinical practice. The external part of the catheter is usually fixed beside the ear in the form of a dressing covered with adhesive tape. This traditional fixing method has the disadvantages of poor firmness, skin sensitivity caused by long-term sticking of the adhesive tape, and an abrupt appearance.
[0003] To achieve the limitation of the hemodialysis tube, the existing device fixes the hemodialysis tube by passing it through a hanging ear type limiting sleeve. However, only fixing the hemodialysis tube through the limiting sleeve will have the following problems:
[0004] 1. Since the material of the hemodialysis tube is relatively hard and the limiting sleeve does not fix the pipe orifice end, there is a risk of friction between the pipe orifice wrapped by the gauze and the patient's skin, etc., which may cause discomfort or even swelling of the patient's neck side skin;
[0005] 2. Only fixing the hemodialysis tube through the hanging ear type limiting sleeve, when the hanging ear type limiting sleeve falls off or shifts, it will cause the hemodialysis tube to fall off or move, which may lead to symptoms such as blood loss in the patient, endangering the patient's physical health;
[0006] 3. Simply fixing the hemodialysis tube through the hanging ear type limiting sleeve, the orifice of the hemodialysis tube is exposed outside, which is not beautiful enough, resulting in a sense of stigma for the patient. Summary of the Invention
[0007] In order to solve the above problems, the purpose of the utility model is to provide a temporary hemodialysis neck tube protection and fixing cap, which strengthens the fixation of the hemodialysis tube through double fixation of the pipe orifice and the pipe body, increases the aesthetics, and at the same time avoids the discomfort caused by friction between the pipe orifice and the patient.
[0008] To achieve the above purpose, the utility model adopts the following technical solutions:
[0009] A temporary blood dialysis neck tube protection and fixation cap, comprising a cap-shaped head fixing member, a pipe orifice limiting assembly arranged on one side of the brim of the head fixing member and slidably connected to the head fixing member, and an ear hook limiting assembly fixed on the side of the head fixing member where the pipe orifice limiting assembly is provided; the pipe orifice limiting assembly includes a fixing plate connected to the head fixing member, a fixing rod fixed to the bottom of the fixing plate, elastic clamping members symmetrically arranged on both sides of the fixing rod, and a sleeve slidably connected to the fixing plate; the inner wall of the sleeve abuts against the elastic clamping members; the ear hook limiting assembly includes an ear hook detachably connected to the head fixing member and used for hanging on the ear, a fixing block fixed on the upper side of the ear hook, and a gripper rotatably connected to the fixing block and used for clamping the blood dialysis tube.
[0010] Preferably, a collar is fixed to the outer wall of the sleeve, and the collar is elastically connected to the fixing plate through a first spring.
[0011] Preferably, the elastic clamping member includes an elastic steel plate fixedly connected to the fixing rod and a clamping plate fixed to the bottom end of the elastic steel plate close to the fixing rod; the two clamping plates cooperate to clamp the pipe orifice of the blood dialysis tube.
[0012] Preferably, the head fixing member includes a heat preservation layer in contact with the patient's head, a hard shell fixing layer fixed to the outside of the heat preservation layer, and a decorative layer fixed to the outside of the hard shell fixing layer; the fixing plate is fixed to the hard shell fixing layer, and the top of the sleeve passes through the decorative layer and is slidably connected to the decorative layer; the ear hook limiting assembly is fixedly connected to the hard shell fixing layer.
[0013] The utility model has the following beneficial effects:
[0014] 1. Through the cooperation of the pipe orifice limiting assembly and the ear hook limiting assembly, the utility model can realize double fixation of the blood dialysis tube, avoid the movement of the blood dialysis tube when one of the limiting assemblies is damaged, and thus increase the firmness of the device;
[0015] 2. Through the cooperation of the elastic clamping member, the fixing rod, the fixing plate and the sleeve, the utility model can fix the pipe orifice of the blood dialysis tube and place the pipe orifice in the sleeve at the same time, so as to avoid the friction between the covered pipe orifice and the patient's hair, skin, etc., and further avoid the discomfort and redness of the patient's neck side skin caused by friction;

[0030] The working principle of this device is as follows:
[0031] When using the device, first put the head fixing part 1 on the patient's head. Then, by squeezing the two clamping arms at the tail end of the gripper 33 inward, the clamping arms are made to closely adhere to the wall of the hemodialysis tube, so as to clamp the hemodialysis tube. Next, pull the sleeve 24 upward, place the tube orifice of the hemodialysis tube between the two elastic clamping parts 24, and release the sleeve 25. Under the action of the first spring 22, while the sleeve 25 moves downward, it pushes the two elastic clamping parts 24 to rotate towards each other, thereby clamping the tube orifice; when disassembly is required, only need to slide the sleeve 25 upward, and the two elastic clamping parts 24 automatically rotate outward under the action of the elastic force, thereby releasing the clamping of the tube orifice. Then release the gripper 33, so that the hemodialysis tube can be taken out from between the two clamping arms; in this device, in order to prevent a large amount of dust from entering the sleeve 25 and increase the weight of the sleeve 25, a sealing plug (not shown in the figure) can be added to the top of the sleeve 25; in order to prevent damage to the hemodialysis tube caused by the inner side of the gripper 33 when clamping the hemodialysis tube, a soft pad (not shown in the figure) can be fixed inside the gripper 33, and at the same time, a scale (not shown in the figure) can be marked on the inner side of the soft pad, so as to facilitate the judgment of the position of the hemodialysis tube.
