Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a puncture tube fixation device. Background Technology

[0002] Dialysis is a medical procedure used to treat kidney failure by purifying the blood to remove waste products and excess water from the body. There are two main types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis involves drawing the patient's blood out of the body, passing it through a device called a dialyzer for purification, and then returning the purified blood to the body. Dialyzers are typically made of hollow fibers with tiny pores that allow waste products and excess water to pass through while retaining essential components such as red blood cells, platelets, and proteins. During dialysis, the dialysate comes into contact with the blood in the dialyzer, and metabolic waste products such as urea, phosphate, and creatinine are transferred from the blood to the dialysate through a semi-permeable membrane.

[0003] Because dialysis takes a long time, some patients may move around during the process, causing the dialysis tubing to pull on the puncture needle and leading to its displacement and dislodgement. Displaced needles can cause significant blood loss. Therefore, this invention proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to address the problem that, due to the long dialysis time, some patients may move around during the dialysis process, causing the dialysis tubing to pull on the puncture needle, resulting in the needle dislodging and falling out. This dislodged needle can cause a large amount of blood loss in the patient.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A puncture tube fixation device was used to improve the above-mentioned problems.

[0007] The present invention is as follows:

[0008] The device includes a finger connector and a tubing fixing part. The finger connector is used to connect to the patient's limb, and the tubing fixing part is used to fix the dialysis tubing. The tubing fixing part is fixedly installed on the top of the finger connector. The bottom of the finger connector has an opening. The tubing fixing part has multiple evenly distributed slots running through it. An auxiliary fixing mechanism is installed on the outside of the finger connector. Both the finger connector and the tubing fixing part are made of elastic material.

[0009] As a preferred technical solution of this utility model, the finger connection part includes an annular retaining ring with a notch at the bottom, and a first Velcro fastener is fixedly connected to the side wall of the retaining ring.

[0010] As a preferred technical solution of this utility model, the inner wall of the retaining ring is fixedly connected with a first anti-slip plate.

[0011] As a preferred technical solution of this utility model, the auxiliary fixing mechanism includes a mounting base fixedly connected to the outer wall of the snap ring, a soft connecting strap connected to the bottom of the mounting base, and a second hook and loop fastener that cooperates with the first hook and loop fastener fixedly connected to the connecting strap.

[0012] As a preferred technical solution of this utility model, the pipeline fixing part includes a base plate fixedly connected to the top of the finger connection part, and a first side plate and a second side plate with an arc cross-section are symmetrically installed on the top of the base plate. A partition plate fixedly connected to the top of the base plate is provided between the first side plate and the second side plate.

[0013] As a preferred technical solution of this utility model, the inner sides of the first side plate and the second side plate are provided with second anti-slip pieces, and the two side walls of the partition facing the first side plate and the second side plate are inlaid with third anti-slip pieces.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] By incorporating a finger connector and a tubing fixation part, the finger connector is secured to the patient's finger during use. The dialysis tubing is then fixed inside the tubing fixation part via a slot. As the patient's arm moves, the tubing moves with it, preventing the tubing from pulling on the puncture needle due to patient movement during dialysis. This also prevents the puncture needle from dislodging. An auxiliary fixation mechanism further secures the finger connector to the patient's finger during use, preventing it from detaching from the patient's limb. Attached Figure Description

[0029] like Figures 1-5As shown, this embodiment proposes a puncture tubing fixator, including a finger connection part 1 and a tubing fixation part 2. The finger connection part 1 is used to connect to the patient's limb, and the tubing fixation part 2 is used to fix the dialysis tubing. The tubing fixation part 2 is fixedly installed on the top of the finger connection part 1. The bottom of the finger connection part 1 has an opening, and the tubing fixation part 2 has multiple evenly distributed slots 4 extending through it. An auxiliary fixation mechanism 3 is installed on the outside of the finger connection part 1. Both the finger connection part 1 and the tubing fixation part 2 are made of elastic material. By setting the finger connection part 1 and the tubing fixation part 2, the finger connection part 1 is locked onto the patient's finger during use, and then the dialysis tubing is inserted. The dialysis tubing is secured inside the tubing fixing part 2 by the slot 4. When the patient's arm moves, the tubing moves with it, thus preventing the tubing from pulling on the puncture needle due to the patient's movement during dialysis. This also prevents the puncture needle from shifting or coming out. By setting an auxiliary fixing mechanism 3, the finger connection part 1, which is stuck on the patient's finger, can be fixed again during use, thus preventing the finger connection part 1 from falling off the patient's limb. The elastic material of the finger connection part 1 can be used by patients with different finger sizes. The elastic material of the tubing fixing part 2 makes it easy to fix dialysis tubing of different diameters.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the finger connecting part 1 further includes an annular retaining ring 101 with a notch at the bottom, and a first Velcro 103 is fixedly connected to the side wall of the retaining ring 101. It should be noted that, in use, the retaining ring 101 is fastened to the patient's finger through its bottom notch, and the first Velcro 103 facilitates the use of the connecting strap 302 and the second Velcro 303.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a first anti-slip piece 102 is further fixedly connected to the inner wall of the retaining ring 101. It should be noted that the first anti-slip piece 102 prevents the retaining ring 101 stuck on the patient's finger from moving.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the auxiliary fixing mechanism 3 further includes a mounting base 301 fixedly connected to the outer wall of the retaining ring 101. A soft connecting strap 302 is connected to the bottom of the mounting base 301, and a second hook-and-loop fastener 303, which cooperates with the first hook-and-loop fastener 103, is fixedly connected to the connecting strap 302. It should be noted that when the retaining ring 101 is fastened to the patient's finger, tightening the connecting strap 302 will attach the second hook-and-loop fastener 303 to the first hook-and-loop fastener 103, thus tightening the retaining ring 101 and better fixing it to the patient's finger.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the tubing fixing part 2 further includes a base plate 201 fixedly connected to the top of the finger connecting part 1. A first side plate 202 and a second side plate 203 with an arc-shaped cross-section are symmetrically installed on the top of the base plate 201. A partition 204 fixedly connected to the top of the base plate 201 is provided between the first side plate 202 and the second side plate 203. It should be noted that the arc-shaped first side plate 202 and second side plate 203 can reduce the compression of the dialysis tubing stuck between the first side plate 202, the second side plate 203, and the partition 204, avoiding affecting the flow of blood within the dialysis tubing. The partition 204 can cooperate with the first side plate 202 and the second side plate 203 to hold the dialysis tubing in place, while also separating the two dialysis tubing.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a second anti-slip piece 205 is further provided on the inner side of both the first side plate 202 and the second side plate 203, and a third anti-slip piece 206 is embedded in both side walls of the partition 204 facing the first side plate 202 and the second side plate 203. It should be noted that the provision of the second anti-slip piece 205 and the third anti-slip piece 206 can prevent the dialysis tubing stuck between the first side plate 202, the second side plate 203, and the partition 204 from slipping.

[0035] Specifically, the working principle of this puncture tubing fixation device is as follows: When in use, the elastic retaining ring 101 is pried open and secured to the patient's finger through its bottom notch. Then, the connecting strap 302 is tightened to attach the second Velcro 303 to the first Velcro 103, thus tightening the retaining ring 101. After the retaining ring 101 is tightened, the two dialysis tubing are inserted between the first side plate 202, the second side plate 203, and the partition 204 through the gap between the top of the partition 204 and the first side plate 202 and the second side plate 203. When installing the dialysis tubing, the elastic first side plate 202 and the second side plate 203 can be pried open outwards to facilitate the insertion of the dialysis tubing between the first side plate 202, the second side plate 203, and the partition 204.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
