Technical Field

[0001] The present application relates to the technical field of medical appliances, and in particular to an adjustable fixer for a hemodialysis tube. Background Art

[0002] In the treatment of some diseases, patients need to undergo hemodialysis. Hemodialysis requires intubation of the patient to transport blood into the patient's body through the hemodialysis tube.

[0003] In the related art, in order to ensure that the hemodialysis tube can smoothly deliver blood to the patient's body, medical staff generally fix the hemodialysis tube on the patient's skin with a simple breathable tape to avoid the position of the hemodialysis tube being shifted. However, directly fixing the hemodialysis tube completely on the patient's skin will make the patient feel uncomfortable and it is not convenient for the patient to adjust his posture. Especially in the medical method of delivering blood in artificial liver DPMAS treatment, the hemodialysis tube is directly fixed on the patient's neck with a breathable tape, which will cause the patient's head to be unable to move.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0005] The purpose of the present application is to provide an adjustable fixer for a hemodialysis tube, so as to prevent the hemodialysis tube from being completely fixed on the patient's skin, causing the patient to be unable to make any posture changes, and to improve the comfort of use.

[0006] The present application provides an adjustable fixer for a hemodialysis tube, comprising: a hemodialysis tube, a catheter sleeve, an adhesive sheet, a mounting bracket and a Velcro tape;

[0031] Please refer to Figure 1 and Figure 2 Some embodiments of the present application provide an adjustable fixer for a hemodialysis tube, comprising: a hemodialysis tube 1, a catheter sleeve 2, an adhesive sheet 3, a mounting bracket 4 and a Velcro 5;

[0032] The mounting bracket 4 is fixed on the front side of the adhesive sheet 3;

[0033] One end of a plurality of hook and loop fasteners 5 is fixed on the front of the adhesive sheet 3 and is located above the mounting bracket 4, and is used to fasten and limit the extension direction of the hemodialysis tube 1 on the adhesive sheet 3. The other end of the hook and loop fasteners 5 has a first hook and loop portion 51 that can be fastened and fixed on the adhesive sheet 3.

[0034] The catheter sleeve 2 is fixed on the hemodialysis tube 1 and is detachably mounted on the mounting bracket 4 .

[0035] Specifically, in this embodiment, the back side of the adhesive sheet 3 is used to be adhered to the patient's skin.

[0036] More specifically, the hemodialysis tube 1 can be a single-input single-output pipe or a multi-input single-output pipe. The adjustable fixer of the hemodialysis tube of the embodiment of the present application is particularly suitable for the latter. Taking the dual-input single-output hemodialysis tube 1 as an example, the catheter sleeve 2 is installed at the position where the dual-input pipe of the hemodialysis tube 1 transitions to the single-output pipe, so that the hemodialysis tube 1 is fixed to the adhesive patch 3 based on the transition position as a fulcrum, thereby ensuring that the hemodialysis tube 1 can be fixed to the patient's skin while ensuring smooth flow of the pipe.

[0037] It should be noted that in the embodiment of the present application, the side of the catheter sleeve 2 close to the output end of the hemodialysis tube 1 is defined as the lower side, and the other side is defined as the upper side, that is, the hemodialysis tube 1 transports blood from top to bottom in the direction of blood input.

[0038] More specifically, the catheter sleeve 2 can basically fix the transition position of the hemodialysis tube 1, ensuring that the output end below the hemodialysis tube 1 can be accurately connected to the human blood vessel for blood transportation; in order to ensure that the input end of the hemodialysis tube 1 can smoothly input blood and not affect the patient's posture changes as much as possible, the adjustable fixer of the hemodialysis tube of the embodiment of the present application is provided with a Velcro 5 above the mounting bracket 4, so that after the hemodialysis tube 1 is fixed to the adhesive sheet 3 through the cooperation of the catheter sleeve 2 and the mounting bracket 4, the extension direction of the hemodialysis tube 1 (i.e., the extension direction of the hemodialysis tube 1 from the catheter sleeve 2 upward through the Velcro 5) is limited based on the Velcro 5, wherein the Velcro 5 is fastened to the front side of the adhesive sheet 3 through the first Velcro portion 51 to form a A tube hole is formed through which the hemodialysis tube 1 can extend out to limit the extending direction of the hemodialysis tube 1. The input end of the hemodialysis tube 1 extends upward based on the tube hole, and can swing freely in the tube hole without affecting the infusion effect, so as to avoid the problem that the input end of the hemodialysis tube 1 is completely fixed on the patient's skin, resulting in the patient being unable to make any posture changes and even causing discomfort to the patient, and also avoids the problem that the input end of the hemodialysis tube 1 is excessively bent and causes poor infusion. In addition, the coverage range and size of the tube hole can be adjusted by changing the fastening position of the first fastening portion 51 and the front fastening of the adhesive sheet 3, and the input direction of the hemodialysis tube 1 can be adaptively adjusted according to the use requirements and the characteristics of the patient's skin appearance to meet the use requirements.

[0039] More specifically, the provision of a plurality of Velcro strips 5 can provide multiple limiting guides for the input end of the hemodialysis tube 1 to ensure that blood can be smoothly input therein.

[0040] It should be noted that the adjustable fixer of the hemodialysis tube in the embodiment of the present application is particularly suitable for adjusting and fixing the hemodialysis tube 1 that transports blood in artificial liver DPMAS treatment.

[0041] The adjustable fixer of the hemodialysis tube in the embodiment of the present application performs secondary fixation on the hemodialysis tube 1 based on the catheter sleeve 2 and the Velcro 5, wherein the catheter sleeve 2 cooperates with the mounting bracket 4 to fix the transition position of the hemodialysis tube 1 on the adhesive sheet 3, which can ensure that the output end of the hemodialysis tube 1 can be accurately connected to the human blood vessel for blood transportation. The Velcro 5, based on the fixing effect of the catheter sleeve 2, fastens the adhesive sheet 3 based on the first Velcro portion 51 to form a tube hole that limits the extension direction of the hemodialysis tube 1, so that the hemodialysis tube 1 can swing freely in the tube hole, so as to avoid the problem that the input end of the hemodialysis tube 1 is completely fixed on the patient's skin, resulting in the patient being unable to make any posture changes or even causing discomfort to the patient, and the Velcro position of the first Velcro portion 51 can be adjusted according to the use requirements, which can simultaneously meet the needs of smooth infusion and optimized patient comfort.

[0042] In some preferred embodiments, the catheter sleeve 2 has a mounting clamp 21 extending toward both sides, the mounting clamp 21 has a clamping hole 22, the mounting bracket 4 has a boss 41 that can cooperate with the clamping hole 22, and the mounting bracket 4 also has a flip cover 42 on both sides that can cooperate with the boss 41 and the clamping hole 22 to fix the catheter sleeve 2 thereon.

[0043] Specifically, Figure 2 As shown, the flip cover 42 has a matching hole corresponding to the position of the boss 41, and the flip cover 42 can be flipped and snapped onto the mounting bracket 4; in the actual process of fixing the hemodialysis tube 1, the user can place the catheter sleeve 2 on the mounting bracket 4 by matching the clamping hole 22 with the boss 41 to achieve preliminary positioning of the hemodialysis tube 1, and then flip the flip cover 42 to allow the boss 41 to pass through the matching hole on the flip cover 42 and snap the flip cover 42 onto the mounting bracket 4, so that the mounting clamping plate 21 is clamped and fixed on the mounting bracket 4 by using the flip cover 42 and the mounting bracket 4 to achieve fixation of the catheter sleeve 2.

[0044] More specifically, the flip cover 42 can be hinged to the mounting bracket 4, or can be separated from the mounting bracket 4 so as to be mounted on the mounting bracket 4 in a detachable buckle mounting manner.

[0045] In some preferred embodiments, the mounting clamp 21 is rotatably mounted on the catheter sleeve 2 , and the boss 41 is slidably mounted on the mounting bracket 4 .

[0046] Specifically, in actual use, the skin where the adhesive patch 3 is located is uneven, especially when used to transport blood in artificial liver DPMAS treatment, the hemodialysis tube 1 needs to be fixed on the patient's neck, and the integrated fixed mounting clamp 21 cannot match the patient's skin well for installation. Therefore, the adjustable fixture of the hemodialysis tube of the embodiment of the present application rotates the mounting clamp 21 to be installed on the catheter sleeve 2, so that the two mounting clamps 21 can form a certain acute angle and be installed on the mounting bracket 4, and the slidingly installed boss 41 can be adaptively adjusted according to the position of the clamping hole 22 on the deflected mounting clamp 21 to ensure that the catheter sleeve 2 can be smoothly fixed on the mounting bracket 4.

[0047] In some preferred embodiments, the material of the mounting bracket 4 is preferably flexible plastic, which can be flexibly adjusted in shape according to the patient's skin shape characteristics to reduce the patient's discomfort; in this embodiment, the rotatable mounting card plate 21 can also be adaptively installed according to the mounting bracket 4 after shape adjustment.

[0048] In some preferred embodiments, there are multiple Velcro fasteners 5, and they are distributed up and down.

[0049] Specifically, the multiple Velcro strips 5 distributed up and down can form tube holes of different sizes and coverage ranges according to the adjustable range of the hemodialysis tube 1 (without affecting the deflection angle range of normal infusion) to guide the hemodialysis tube 1 to extend upward.

[0050] More specifically, if Figure 1 As shown, a plurality of Velcro strips 5 may be arranged in a left-right cross pattern to form an upper and lower distribution.

[0051] In some preferred embodiments, since the adjustable range of the hemodialysis tube 1 is larger as it is closer to the upper side, the length of the Velcro 5 on the upper side is greater than the length of the Velcro 5 on the lower side, so that the Velcro 5 on the upper side can form a larger tube hole.

[0052] In some preferred embodiments, the middle portion of the topmost hook and loop fastener 5 has a second hook and loop portion 52 that can be adhered and fixed to the adhesive sheet 3 .

[0053] Specifically, when the hemodialysis tube 1 adopts a multi-input single-output pipeline, different inputs need to be guided to connect different medical devices. The top layer of Velcro 5 is provided with a second Velcro portion 52 that can form at least two tube holes to separate the input ends of the hemodialysis tube 1, so as to achieve guidance and adjustment of different input ends.

[0054] In some preferred embodiments, the first hook and loop fastener portion 51 includes Velcro.

[0055] In some preferred embodiments, the second hook and loop fastener portion 52 includes Velcro.

[0056] Specifically, the Velcro 5 can be quickly fixed based on Velcro, and can easily and repeatedly adjust the tube hole, which is convenient for adjusting the extension direction of the hemodialysis tube 1.

[0057] In some preferred embodiments, a soft pad 6 is provided between the mounting bracket 4 and the adhesive sheet 3 .

[0058] Specifically, the adjustable fixer of the hemodialysis tube in the embodiment of the present application is provided with a soft gasket 6 to separate the mounting bracket 4 and the adhesive sheet 3, which can improve the patient's comfort and reduce the discomfort felt by the patient in contact with hard objects.

[0059] In some preferred embodiments, the adhesive sheet 3 includes a breathable adhesive tape 31 .

[0060] In some preferred embodiments, the adhesive sheet 3 further includes a lining layer 32 disposed on the front side of the breathable adhesive tape 31 to facilitate installation of the mounting bracket 4 and fastening and fixing of the Velcro tape 5 .

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "certain embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the utility model.
