Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an ear-hook type dialysis catheter fixation device. Background Technology

[0002] Hemodialysis is a form of kidney replacement therapy. The principle of hemodialysis is to draw blood from the patient's body, pass it through hemodialysis tubing and a hemodialysis machine, and then, through the diffusion, convection, and adsorption functions of the dialyzer, remove toxins and excess water from the body, maintaining electrolyte and acid-base balance. Clinically, the main indications for hemodialysis are acute kidney injury and chronic kidney failure. It can also be used for acute drug or poisoning.

[0003] Currently in clinical practice, hemodialysis catheters are typically secured using simple adhesive tape. However, this can sometimes be improperly fixed, causing local discomfort and pain, and carries the risk of catheter slippage and infection. Prolonged use of medical tape on the patient's skin can damage the skin, even leading to ulceration. Furthermore, it can create a psychological burden on the patient, as the presence of blood residue in the dialysis catheter can cause distress for both the patient and their family.

Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the protection scope of this utility model.

[0028] Please see Figure 1-3This embodiment provides an ear-hook type dialysis catheter fixing device, which includes a catheter fixing assembly 1, the catheter fixing assembly 1 including a tightening sleeve 11, a support tube 12 is sleeved inside the tightening sleeve 11, the inner diameter of the support tube 12 is adapted to the outer diameter of the dialysis catheter, and a first connecting piece 13 is vertically arranged on the side of the tightening sleeve 11; and an ear hook assembly 2, the ear hook assembly 2 including a hook-shaped ear hook rod 21, a second connecting piece 22 is vertically arranged on the hook-shaped ear hook rod 21, and the second connecting piece 22 is detachably connected to the first connecting piece 13.

[0029] Specifically, when a patient needs temporary dialysis, the dialysis catheter is usually connected at the neck. The dialysis tubing needs to extend upwards from the patient's neck. First, the dialysis catheter is passed through the support tube 12 inside the elastic sleeve 11. When it reaches the appropriate position, the medical staff pulls the elastic sleeve 11, keeping the relative position of the elastic sleeve 11 and the dialysis catheter unchanged. The support tube 12 is then pulled out from the elastic sleeve 11 and then from the dialysis catheter. At this time, the elastic sleeve 11 tightens, wrapping around the dialysis catheter and fixing it together with the dialysis catheter. The elastic sleeve 11 and the hook-shaped ear rod 21 are connected through the first connecting piece 13 and the second connecting piece 22. The hook-shaped ear rod 21 is then hung on the patient's ear, completing the fixation of the dialysis catheter at the patient's ear and preventing the dialysis catheter from slipping and causing discomfort to the patient. At the same time, the elastic sleeve 11 covers more of the dialysis catheter, hiding it as much as possible and reducing the patient's psychological burden. It also wraps around more areas to better fix and protect the dialysis catheter.

[0030] In some possible implementations, the first connecting piece 13 is provided with M male concealed snap fasteners 14 at vertical intervals, and the second connecting piece 22 is provided with N female concealed snap fasteners 23 at vertical intervals, where M and N are both integers. The distance between two adjacent male concealed snap fasteners 14 is the same as the distance between two adjacent female concealed snap fasteners 23. Several male concealed snap fasteners 14 are detachably connected to the corresponding female concealed snap fasteners 23, so that the first connecting piece 13 and the second connecting piece 22 are detachably connected.

[0031] Specifically, when in use, the male snap fastener 14 of the first connecting piece 13 is snapped onto the female snap fastener 23 of the second connecting piece 22 in sequence, and the snap fastener connection makes it more convenient to use.

[0032] In some possible implementations, the vertical length of the second connecting piece 22 is greater than the vertical length of the first connecting piece 13, and N is greater than M.

[0033] Specifically, the second connecting piece 22 is longer, and there are more vertical concealed female buckles 23, while the first connecting piece 13 has fewer concealed male buckles 14. In use, the position of the first connecting piece 13 connected to the second connecting piece 22 can be changed according to the actual use situation, and the height of the first connecting piece 13 can be adjusted, thereby adjusting the height of the elastic sleeve 11 and the internal dialysis catheter.

[0034] In some possible implementations, the ear hook assembly 2 further includes: an elastic cloth 24, and a second connecting piece 22 is vertically mounted on the hook-shaped ear hook rod 21 via the elastic cloth 24.

[0035] Specifically, the elastic fabric 24 is a piece of fabric with a certain degree of elasticity. The second connecting piece 22 is connected to the hook-shaped ear rod 21 through the elastic fabric 24. The dialysis catheter is wrapped in the elastic sleeve 11. The elastic sleeve 11 is connected to the hook-shaped ear rod 21 through the first connecting piece 13, the second connecting piece 22 and the elastic fabric 24. When the patient moves, the dialysis catheter and the connected elastic sleeve 11 will shake. The elasticity of the elastic fabric 24 plays a certain role in cushioning the shaking. The impact of shaking on the hook-shaped ear rod 21 is relatively reduced, improving the patient's wearing comfort.

[0036] In some possible implementations, the elastic sleeve 11 includes an elastic section 111 and an easy-tear section 112, which together form the elastic sleeve 11. The cross-sectional arc length of the elastic section 111 is greater than the cross-sectional arc length of the easy-tear section 112, and a serrated easy-tear opening 113 is vertically provided in the middle of the easy-tear section 112.

[0037] Specifically, after a temporary dialysis session is completed, the elastic band 11 needs to be separated from the dialysis catheter. The tear-off section 112 of the elastic band is provided with a serrated tear-off opening 113. Medical staff can directly tear the tear-off section 112 in the middle along the serrated tear-off opening 113, thereby opening the entire elastic band 11 and separating the dialysis catheter from the elastic band 11. The elastic section 111 ensures that the elastic band 11 as a whole can wrap and fix the dialysis catheter.

[0038] In some possible implementations, the first connecting piece 13 is vertically disposed on the elastic section 111, and the position of the first connecting piece 13 is opposite to the position of the serrated easy-tear opening 113. The elastic section 111 is made of rubber, and the easy-tear section 112 is made of plastic.

[0039] Specifically, the first connecting piece 13 and the serrated easy-tear opening 113 are located on opposite sides of the entire elastic sleeve 11, and do not affect each other during use; the rubber material and the plastic material respectively meet the usage requirements of the elastic section 111 and the easy-tear section 112, and are also cheaper to manufacture.

[0040] In some possible implementations, the hook-shaped part of the hook-shaped ear rod 21 is adapted to the shape of the human ear auricle.

[0041] Specifically, the hook-shaped ear hook 21 fits the patient's auricle more closely, making it more comfortable and stable for the patient to wear.

[0042] In some possible implementations, the length of the support tube 12 is greater than the length of the elastic sleeve 11. The hook-shaped hanging rod 21 is made of silicone.

[0043] Specifically, the length of the support tube 12 is shorter than that of the elastic sleeve 11, making it easier to pull the support tube 12 out of the elastic sleeve 11 after the dialysis catheter is inserted into it; the silicone material is relatively lightweight and reduces the risk of allergic reactions in patients due to material issues.
