Description

Technical Field

[0001] The present invention belongs to the field of medical equipment, and more specifically relates to an angle-adjustable catheter fixing device and an angle adjustment method. Background Art

[0002] The catheter fixing device is used to fix various catheters to prevent them from slipping during use and affecting their effectiveness. In regional thermal circulation perfusion therapy, one of the perfusion tubes is a catheter inserted under ultrasound guidance. During use, the perfusion tube will change position with the patient's breathing, the movement of the visceral organs in the cavity, and the impact of the thermal circulation of the abdominal fluid.

[0003] In order to ensure the water outflow speed of the patient's catheter, the angle and direction of the catheter must be adjusted at any time. Usually, the transparent sticky dressing that fixes the catheter on the patient's skin is torn off, so there is no dressing or device to fix the catheter during the perfusion process.

[0004] At present, after the catheter is adjusted, there is a certain angle and direction between it and the puncture point where it pierces the skin, and the position of the catheter needs to be fixed manually. Not only is there a risk of the catheter slipping off at any time during perfusion, but the angle and direction of the catheter are also prone to change, which in turn affects the speed at which the thermal circulation fluid flows out of the body and affects the treatment effect. In addition, repeated adjustments of the catheter will also cause pain, irritation and other discomfort to the patient, while increasing the workload of medical staff. Summary of the invention

[0036] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0037] See attached Figure 1 To Attachment Figure 7 As shown, a catheter fixing device with adjustable angle includes a base 1 that can be adhered to the patient's skin surface, a fixing bracket 2 arranged on the top of the base 1, a connecting component 3 that allows the fixing bracket 2 to rotate relatively, a buckle component for fixing the catheter, and a detachable hook arranged on the outer side wall of the base 1, one end of the hook is provided with a curved surface for placing the catheter, and the other end of the hook can be snapped onto the edge of the top of the base 1.

[0038] In one embodiment of the present invention, the fixed bracket 2 is used to adjust the angle and height of the catheter, and is vertically arranged on the top of the base 1, including a first bracket 21 coaxially arranged with the base 1, three bayonet holes 22 for fixing the catheter are arranged at intervals on the side of the first bracket 21, and an opening 212 is arranged from top to bottom on the side of the first bracket 21. The opening 212 extends from the top of the first bracket 21 to the bottom, and the opening 212 is respectively connected to each bayonet hole 22. The first bracket 21 can be connected to the base 1 as a whole, and is about 5 cm high.

[0039] In one embodiment of the present invention, the first bracket 21 and the base 1 are respectively provided with a first guide hole 211 and a second guide hole 11 through which the catheter can pass, and the first bracket 21 and the base 1 are connected through the first guide hole 211 and the second guide hole 11.

[0040] In one embodiment of the present invention, the diameter of the second guide hole 11 is 0.2 cm larger than the diameter of the catheter, the inner diameter of the second guide hole 11 is larger than or equal to the inner diameter of the first guide hole 211, and the inner diameter of the first guide hole 211 is larger than the diameter of the catheter to facilitate smooth passage of the catheter.

[0041] In one embodiment of the present invention, three bayonet holes 22 are sequentially arranged along the height direction of the first bracket 21, and the width of the opening 212 is set to be larger than the diameter of the catheter, and the width of the bayonet hole 22 is set to be slightly smaller than or equal to the diameter of the catheter, so that after the catheter passes through the opening 212, it is adjusted to the optimal position and height and finally fixed at the corresponding bayonet hole 22.

[0042] In one embodiment of the present invention, referring to the attached Figure 4 In order to fix the catheter after it is installed in the corresponding bayonet 22, a buckle assembly for fixing the catheter is provided between adjacent bayonet 22, and the buckle assembly includes a magic hook 61 and a magic tape 62 fixed to the bottom of the corresponding bayonet 22 by riveting. The magic hook 61 and the magic tape 62 are respectively arranged on both sides of the opening 212, so that when in use, the fixation can be completed by placing the fur surface of the magic tape 62 on the magic hook 61, which can prevent the catheter from sliding downward.

[0043] In one embodiment of the present invention, each bayonet 22 is divided into two parts, a left bayonet and a right bayonet, by a vertically arranged opening 212. When the catheter passes through the opening 212 and the final bayonet 22 is selected, the catheter can be fixed to the left bayonet or the right bayonet to fine-tune the lateral position of the catheter, thereby increasing practicality.

[0044] In one embodiment of the present invention, the connecting component 3 includes an elastic sleeve 31 of a rubber or silicone material component that can be plugged into the top of the base 1 and a third guide hole arranged in the elastic sleeve 31 for the first bracket 21 to pass through.

[0045] In one embodiment of the present invention, the first bracket 21 is cylindrical, and the inner diameter of the third guide hole is larger than the diameter of the first bracket 21, so that the first bracket 21 can rotate relative to the elastic sleeve 31. When the catheter passes through the corresponding bayonet 22, it is convenient to adjust the angle and direction of the catheter. Therefore, while ensuring the water outlet speed during the circulation perfusion process, the workload of medical staff can be further reduced to achieve the best treatment effect.

[0046] In one embodiment of the present invention, a limiting assembly 5 for limiting the installation height of the first bracket 21 is provided on the inner wall of the third guide hole. The limiting assembly 5 and the elastic sleeve 31 are integrated components. The limiting assembly 5 can be a rubber ring or a rubber pad embedded in the side wall of the elastic sleeve 31, and a plurality of annular grooves for installing the elastic sleeve 31 can be arranged at intervals on the inner wall of the elastic sleeve 31, and a through hole for the catheter to pass through is provided in the middle of the limiting assembly 5.

While ensuring the adhesive fixing effect, the inconvenience caused by the adhesive layer 4 being too large is avoided, and an outer protective film is provided on the bottom surface of the adhesive layer 4 for easy tearing during use.

[0048] The method for adjusting the height and angle of a catheter by using the angle-adjustable catheter fixing device comprises the following steps:

[0049] Step 1: Wipe the skin around the puncture catheter hole with alcohol, peel off the outer protective film on the lower end of the adhesive layer 4, fix the base 1 to the puncture catheter hole, and make the puncture catheter hole located in the second guide hole 11 to facilitate the subsequent extension of the catheter;

[0050] Step 2: Install the elastic sleeve 31 on the top of the base 1, and then insert the first bracket 21 into the elastic sleeve 31, ensuring that the bottommost bayonet 22 is located above the elastic sleeve 31;

[0051] Step 3: Connect one end of the catheter to the puncture catheter hole, and pass the other end of the catheter through the second guide hole 11, the first guide hole 211 and the opening 212 in sequence, and install the catheter in the corresponding bayonet 22 at the required height;

[0052] Step 4: Place the fur surface of the Velcro 62 corresponding to the bottom of the bayonet 22 on the magic hook 61 to fix it, so as to prevent the catheter from sliding downward;

[0053] Step 5: Rotate the first bracket 21 so that the first bracket 21 rotates relative to the base 1 and the elastic sleeve 31, and adjust so that the angle and direction of the catheter are suitable;

[0054] Step 6: Place the catheter extending from the bayonet 22 into the curved surface at one end of the hook to ensure smooth passage in the catheter, avoid pain and discomfort to the patient caused by natural sagging or random swinging of the catheter, prevent unplanned tube removal, and avoid increasing the workload of medical staff due to repeated adjustment of the pipeline.
