Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a device for preventing hemodialysis tubes from dislodging. Background Technology

[0002] The prior art patent with publication number CN221309241U discloses a hemodialysis tubing fixing device. A connecting tube, a first extended tube, and a second extended tube are connected by a connecting seat. The connecting seat includes an installation tube, on which a fixing device is fixed. The fixing device includes two limiting rings, which are fixedly installed on the installation tube. Two movable rings are provided between the two limiting rings, and connecting blocks are respectively connected to the rear of the two movable rings. The rear of the two connecting blocks is connected to a support pad. A collar is provided between the two movable rings, and an installation block is connected to one side of the collar. A soft strip is connected to the installation block. The soft strip includes a connector and two soft strips. The connector is detachably connected to the installation block. The outer ends of the two soft strips are respectively provided with adhesive parts. The outer ends of the two soft strips are bent inward and then bonded together through the adhesive parts.

[0003] The fixing device described in the above technical solution is fixed to the arm in the form of a wristband. Although this method is convenient and quick to fix and easy to disassemble, the fixing stability is poor and it is easy to shift, which may lead to the risk of the needle coming off. Utility Model Content

[0004] To address the problems of existing technologies: the existing fixing devices are fixed to the arm in the form of a wristband. Although this method is convenient and quick to fix and easy to disassemble, the fixing stability is poor and it is easy to shift, which may lead to the risk of the needle coming off.

[0005] A hemodialysis tube anti-dislodgement device includes a hemodialysis tube body and an anti-dislodgement device. The anti-dislodgement device includes a bottom adhesive, a limiting device is fixedly connected to the top of the bottom adhesive, and butterfly wings are fixedly connected to the outer surface of the hemodialysis tube body. Through holes are opened on the outer surface of the butterfly wings at the positions on both sides of the hemodialysis tube body.

[0006] The limiting device includes a limiting sleeve and a limiting protrusion adapted to the butterfly wing, the limiting protrusion being glued to the top of the bottom sticker.

[0007] Furthermore, a pressing adhesive is also glued to the top of the bottom adhesive.

[0008] Furthermore, a reinforcing sticker is provided between the base sticker and the pressing sticker. The outer surface of the reinforcing sticker has a window, the base sticker is placed at the window, and extension adhesive wings are fixedly connected to both sides of the window.

[0009] Furthermore, the outer surface of the reinforcing patch is provided with graduations along its length.

[0010] Furthermore, the outer surface of the reinforcing patch has serrated indentations near the scale.

[0011] Working principle and beneficial effects: The base patch is applied to the skin surface, and then the butterfly wing on one side of the hemodialysis tube body is embedded in the limiting sleeve. The through hole of the butterfly wing on the other side is embedded in the limiting protrusion glued to the same position to restrict the movement of the hemodialysis tube body. This fixing method is convenient, quick and easy to disassemble. In order to prevent the butterfly wing embedded in the limiting protrusion from falling off, a pressing adhesive is also glued to the top of the base patch, that is, the hemodialysis tube body is located between the base patch and the pressing adhesive.

[0016] like Figure 1 As shown,

[0017] Example 1

[0018] A hemodialysis tube anti-dislodgement device includes a hemodialysis tube body 1 and an anti-dislodgement device. The anti-dislodgement device includes a base patch 2, with a limiting device fixedly connected to the top of the base patch 2. A butterfly wing 3 is fixedly connected to the outer surface of the hemodialysis tube body 1. Through holes are opened on the outer surface of the butterfly wing 3 at both sides of the hemodialysis tube body 1. The limiting device includes a limiting sleeve 4 and a limiting protrusion 5 adapted to the butterfly wing 3. The limiting protrusion 5 is glued to the top of the base patch 2. In use, the base patch 2 is first applied to the skin surface, and then the butterfly wing 3 located on one side of the hemodialysis tube body 1 is embedded in the limiting sleeve 4. The through hole of the butterfly wing 3 on the other side is embedded in the limiting protrusion 5 glued to that position to restrict the movement of the hemodialysis tube body 1. This fixing method is convenient, quick, and easy to disassemble. In order to prevent the butterfly wing 3 embedded in the limiting protrusion 5 from detaching, a pressing sticker 6 is also glued to the top of the base patch 2, that is, the hemodialysis tube body 1 is located between the base patch 2 and the pressing sticker 6.

[0019] In Example 2, to prevent detachment due to the base patch 2 being smaller than the skin and not adhering tightly, a reinforcing patch 7 is provided between the base patch 2 and the pressing patch 6. The reinforcing patch 7 has a larger area than the base patch 2. The reinforcing patch 7 is applied to the skin surface and presses on top of the base patch 2. A window is provided on the outer surface of the reinforcing patch 7, and the base patch 2 is placed at the window. Extension adhesive wings 8 are fixedly connected to both sides of the window. The extension adhesive wings 8 are applied to the top of the base patch 2, which serves to restrict and fix it. When disassembling, the base patch 2 can be removed simply by lifting the adhesive near the window. The outer surface of the reinforcing patch 7 is provided with graduations along its length to facilitate observation of the displacement of the hemodialysis tube body 1, thereby avoiding the risk of needle dislodgement.

[0020] In Example 3, the outer surface of the reinforcing sticker 7 is provided with a serrated indentation 9 near the scale, which makes it easy to tear off the reinforcing sticker 7 with the scale along the serrated indentation 9 and use it for other measurement scales.
