[0002] In hemodialysis treatment, the fixation and protection of the neck hemodialysis catheter is crucial. Currently, existing clinical structures use a drape to wrap the catheter or attach it to the patient's ear with a lanyard. This structure lacks effective protection for the catheter, posing a risk of insecure fixation and easy exposure, increasing the risk of catheter-related infections. Furthermore, it prevents the rapid exposure of the catheter when treatment is needed, hindering quick switching between standby and treatment states. In addition, the opaque surface of the drape makes it impossible to constantly monitor the catheter's condition, hindering healthcare personnel from promptly detecting abnormalities and increasing patient safety risks. Utility Model Content

[0032] Example 1

[0033] In clinical practice, hemodialysis treatment often involves wrapping the hemodialysis catheter in a drape or attaching it to the patient's ear with a lanyard. This structure lacks effective protection for the catheter, posing a risk of insecure fixation and easy exposure, increasing the risk of catheter-related infections. Furthermore, it prevents the rapid exposure of the catheter when treatment is needed, hindering quick switching between standby and treatment states. Additionally, the opaque drape prevents constant monitoring of the catheter's condition, hindering timely detection of abnormalities by healthcare professionals and increasing patient safety risks.

[0034] In view of this, the present invention provides a hemodialysis tube fixing device, comprising: an outer fixing cover 100 and an inner fixing cover 200, the outer fixing cover 100 and the inner fixing cover 200 being rotatably connected, the outer fixing cover 100 being rotatable to overlap with the inner fixing cover 200, so that the hemodialysis tube 300 is fixed between the outer fixing cover 100 and the inner fixing cover 200; or, the outer fixing cover 100 being rotatable to be on the same plane as the inner fixing cover 200, so that the hemodialysis tube 300 is exposed; the bottom surface of the inner fixing cover 200 is provided with a first fixing structure for fixing to the human body.

[0035] The external fixation cover 100 and the internal fixation cover 200 can be opened and closed at any time. When the external fixation cover 100 is rotated to a closed state overlapping the internal fixation cover 200, a closed structure is formed between the external fixation cover 100 and the internal fixation cover 200, and the hemodialysis catheter 300 is fixed between the external fixation cover 100 and the internal fixation cover 200, which can effectively protect the hemodialysis catheter 300 and prevent external contamination and accidental damage. When treatment is required, the external fixation cover 100 can be rotated to an open state where it is on the same plane as the internal fixation cover 200, so that the hemodialysis catheter 300 is exposed to meet the treatment needs and realize the rapid switching between standby and treatment states. The internal fixation cover 200 is fixed to the human body through the first fixing structure and is easy to disassemble, ensuring the stability of the hemodialysis catheter fixation device.

[0036] The hemodialysis catheter fixation device can secure and effectively protect the neck hemodialysis catheter 300, ensuring patient safety; it can also quickly switch between standby and treatment modes, improving ease of use.

[0037] In an optional embodiment, the outer fixing cover 100 and the inner fixing cover 200 are closable by edge Velcro 400, which is respectively provided on the top edge and side edge of the outer fixing cover 100 and the inner fixing cover 200.

[0038] Please see Figure 2Both the top edge of the outer fixation cover 100 and the top edge of the inner fixation cover 200 are provided with edge hook-and-loop fasteners 400, one with a hook side and the other with a rough side. One side of the outer fixation cover 100 and the corresponding side of the inner fixation cover 200 are also provided with edge hook-and-loop fasteners 400, one with a hook side and the other with a rough side. This arrangement ensures a more secure connection between the outer fixation cover 100 and the inner fixation cover 200 in the closed state, effectively protecting the hemodialysis tube 300 fixed between the outer fixation cover 100 and the inner fixation cover 200.

[0039] The external fixation cover 100 and the internal fixation cover 200 can be opened and closed at any time through the edge Velcro 400. When closed, they can effectively protect the hemodialysis tube 300. When treatment is required, they can be quickly opened to expose the hemodialysis tube 300 to meet the treatment needs.

[0040] In an optional embodiment, the first fixing structure includes a fixing hook and loop fastener 500, one side of which is fixed to the bottom of the inner fixing cover 200, and the other side can be attached to the surface of human skin.

[0041] Please see Figure 3 The fastening hook and loop fastener 500 is located on the bottom surface of the inner fixing cover 200, allowing it to directly adhere to the surface of human skin, thereby ensuring the stability of the hemodialysis catheter fixing device. Furthermore, the fastening hook and loop fastener 500 is easy to remove at any time, improving ease of use.

[0042] In an optional embodiment, the inner fixing cover 200 is further provided with a second fixing structure for fixing to the human body.

[0043] Specifically, the second fixing structure includes a neck-wrap fixing strap 600, which can be wrapped around the neck of a human body, and the two ends of the neck-wrap fixing strap 600 are detachably connected to the inner fixing cover 200.

[0044] Please see Figure 1 Both ends of the cervical fixation strap 600 are fixed to the inner fixation cover 200, and the hemodialysis catheter fixation device is fixed by wrapping around the neck. When the patient is in an upright position, the cervical fixation strap 600 can be used to strengthen the fixation, ensure the stability of the hemodialysis catheter fixation device, and facilitate the patient's free movement; when the patient is in a supine position, the cervical fixation strap 600 can be removed so as not to affect the patient's rest.

[0045] In an optional embodiment, a third fixing structure for fixing the hemodialysis tube 300 is provided between the outer fixing cover 100 and the inner fixing cover 200.

[0046] Specifically, the third fixing structure includes a first fixing patch 700, which includes two rotatably connected first strips 710, and the hemodialysis tube 300 can be clamped and fixed between the two first strips 710.

One of the first sticker strips 710 of the first fixing sticker 700 is fixed to the inner fixing cover 200. When the other first sticker strip 710 rotates and the included angle between the two first sticker strips 710 gradually decreases, the hemodialysis tube 300 can be clamped and fixed to prevent the hemodialysis tube 300 from being pulled or displaced. When the other first sticker strip 710 rotates and the included angle between the two first sticker strips 710 gradually increases, the fixation of the hemodialysis tube 300 can be released.

[0048] Furthermore, the third fixing structure also includes a second fixing patch 800, which is disposed opposite to the first fixing patch 700. The second fixing patch 800 includes two rotatably connected second strips 810, and the hemodialysis tube 300 can be clamped and fixed between the two second strips 810.

[0049] Please continue reading Figure 2 A second fixing sticker 800 is provided between the outer fixing cover 100 and the inner fixing cover 200. The second fixing sticker 800 is disposed opposite to the first fixing sticker 700 on both sides of the inner fixing cover 200 along its length. One of the second fixing sticker strips 810 is fixed to the inner fixing cover 200. When the other second fixing sticker strip 810 rotates and the included angle between the two second fixing sticker strips 810 gradually decreases, it can clamp and fix the hemodialysis tube 300 to prevent the hemodialysis tube 300 from being pulled or displaced. When the other second fixing sticker strip 810 rotates and the included angle between the two second fixing sticker strips 810 gradually increases, it can release the fixation of the hemodialysis tube 300.

[0050] In an optional embodiment, both the outer fixing cover 100 and the inner fixing cover 200 are configured as transparent structures.

[0051] Both the external fixation cover 100 and the internal fixation cover 200 are made of transparent material, which allows medical staff to clearly observe the status of the hemodialysis tube 300, making it easier for them to detect abnormalities such as bleeding or blockage in a timely manner, so as to take timely measures and ensure the safety of the patient.

[0052] In this embodiment, the hemodialysis catheter fixation device achieves quick opening and closing between the outer fixation cover 100 and the inner fixation cover 200 through edge Velcro 400. Combined with the bottom fixation of the Velcro 500, the catheter fixation of the first fixation patch 700 and the second fixation patch 800, and the neck fixation of the neck strap 600, this triple fixation method ensures the overall stability and safety of the device. Simultaneously, the transparent structure facilitates real-time observation of the hemodialysis catheter 300's status, providing patients with a safer and more convenient user experience.
