Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a fixing device for a central venous catheter. Background Art

[0002] A central venous catheter (CVC) is a type of intravascular catheter consisting of wings, a catheter body, and branch tubes, with the main body placed in a large vein. It can be used to measure central venous pressure, assess circulatory physiological parameters, administer large amounts of fluids rapidly (to maintain blood pressure during surgery or emergency treatment where significant blood loss is possible), administer long-term parenteral nutrition, long-term antibiotic and analgesic injections, provide a conduit for hemodialysis, and administer chemotherapy for tumors. Currently widely used in clinical practice, it can alleviate patient pain and improve the quality of care. Depending on actual needs, a CVC can be inserted through a peripheral venous puncture for central venous catheterization.

[0003] Existing fixation devices generally use adhesive tape or stockings for fixation, but this method is prone to causing phlebitis in patients, and cannot meet the requirements of long-term fixation. The fixation is not firm and is prone to loosening, causing central venous catheter malposition. Patients who use stockings need to take off the stockings during infusion, which is inconvenient for care. Repeated operations can easily cause the dressing to curl and increase the chance of dressing contamination. Fixation using adhesive tape is prone to leaving tape marks on the patient's skin surface, and it will cause pain to the patient when the tape is removed. Utility Model Content

[0004] The present application provides a fixing device for a central venous catheter to solve the inventor's recognition that existing fixing devices generally use adhesive tape or stockings for fixing, but this method is prone to cause phlebitis in patients, and cannot meet the requirements of long-term fixation. The fixation is not firm and is prone to loosening, causing the central venous catheter to be dislocated. Those who use stockings need to take off the stockings during infusion, which is inconvenient for care. Repeated operations can easily cause the dressing to curl and increase the chance of dressing contamination. Fixation using adhesive tape is prone to leaving tape marks on the patient's skin surface, and the patient will feel pain when the tape is torn off.

[0005] The present application provides a fixing device for a central venous catheter, comprising a fixing belt and a fixing assembly, wherein the fixing assembly is arranged on the surface of the fixing belt, and the fixing assembly is used to detachably connect the two sides of the fixing belt to form a closed ring, and further comprises a reinforcement belt, one end of the reinforcement belt is connected to the front face of the fixing belt, and the other end of the reinforcement belt is detachably connected to the front face of the fixing belt, a groove is provided inside the fixing belt, and the reinforcement belt can cover the groove, and the fixing belt and the reinforcement belt are made of soft material.

[0006] In any of the above technical solutions, further, a cavity is opened inside the fixing belt, a spacer pad is arranged inside the cavity, a sealing belt is arranged on the front of the fixing belt, the bottom of the sealing belt is detachably connected to the front of the fixing belt, the sealing belt is used to seal the cavity, and the spacer pad is made of soft material.

[0007] In any of the above technical solutions, further, a limiting pad is provided on the front side of the sealing belt, and a storage cavity is defined between the limiting pad and the sealing belt.

[0008] In any of the above technical solutions, further, the top and bottom of the back side of the fixing belt are both provided with soft pads.

[0009] In any of the above technical solutions, further, a pipeline clamp is provided on the front side of the fixing belt and above the reinforcement belt.

[0010] In any of the above technical solutions, further, the number of the pipeline clamps is at least one.

[0011] In any of the above technical solutions, further, the pipeline clamp is C-shaped.

[0012] In any of the above technical solutions, further, the number of the sealing strips is at least one, and the number of the cavities, the barrier pads and the limiting pads is consistent with the number of the sealing strips.

[0013] In any of the above technical solutions, further, the fixing component can be a Velcro, a buckle or a snap buckle.

[0014] In any of the above technical solutions, further, the bottom of the sealing belt and the front of the fixing belt are detachably connected via a buckle or a snap buckle.

[0015] The beneficial effects of this application are mainly:

[0016] 1. Fix the fixing belt to the appropriate position of the patient's arm through the fixing component. Then, insert the central venous catheter into the corresponding position of the arm and place it in the groove. Preliminary fixation of the central venous catheter is performed with a C-shaped pipeline clamp. Then, the reinforcement belt is connected to the fixing belt to perform secondary fixation of the central venous catheter. During this process, the fixation is stable and will not cause adverse effects on the patient.

[0017] 2. The cooling patch or the warming pack connected to the packaging bag can be placed in the storage cavity. When the patient is in a cold or hot environment, or when the patient is unwell and needs to keep warm or cool down, the cooling patch or the warming pack can be placed in the cavity and fixed with a sealing tape. The setting of the partition pad can effectively prevent the cooling patch or the warming pack from contacting the skin, so as to avoid adverse effects on the patient.
