Description

Technical Field

[0001] The utility model relates to the production of medical auxiliary equipment, in particular to a universal clip for preventing an infusion set from being pulled out. Background Art

[0002] Infusions, also known as drips or hanging water, are large doses of fluid administered intravenously, typically in glass or plastic bottles or bags. Hyperactivity is common among children during infusions in children's hospitals, and the infusion tube frequently becomes dislodged. Despite nurses providing instruction on preventative measures and procedures for dislodgment upon admission, along with a signed agreement, dislodgment rates continue to increase.

[0003] In existing technologies, due to the active nature of children, infusion sets frequently become detached during infusions, causing the infusion tube to fall off the infusion bag, causing the liquid medicine to leak out of the bag and contaminate the external environment. In actual use, if the infusion tube falls off, the nurse is required to insert the detached infusion set back into the infusion bottle. This not only increases the workload of medical staff, but also leads to liquid contamination and waste of liquid medicine. It also poses a significant safety hazard, is unsafe, and is time-consuming and labor-intensive, making it less practical. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, a universal anti-pullout clamp for an infusion set includes a clamping member and a slot member 3 respectively assembled on a vertical rod 1;

[0024] The clamping member includes a portion 2a and a portion 2b, wherein the portion 2a and the portion 2b are hinged and divided into a clamping portion and an opening and closing control portion according to the hinge as a dividing point;

[0025] The end surface of the clamping member 2 is provided with at least four retention holes 21 which are arranged at equal distances and have decreasing circumferential radius;

[0026] The outer walls of the vertical rod 1 on opposite sides are provided with a constriction groove 11, a waist groove is provided on the vertical rod 1, and the opening and closing control part is slidably arranged on the vertical rod 1, and the constriction groove 11 is located on the sliding track of the opening and closing control part;

[0027] The vertical rod 1 and the slot member 3 are plug-in assembled, and the end section of the slot opening 31 opened at the end of the slot member 3 is coaxial with the axis of the retention hole 21 .

[0028] Specifically, the clamping member 2 in the above embodiment is a hard plate member, combined with Figure 1 As can be seen, the a portion 2a and b portion 2b in the embodiment are hinged to form the clamping portion and the opening and closing control portion. That is, by controlling the opening and closing control portion to reduce the spacing, the opening of the clamping portion is increased. The corresponding opening and closing control portions a portion 2a and b portion 2b slide on the vertical rod 1 and the constriction groove portion 11, respectively.

[0029] In the embodiment, there are no less than four retention holes 21 , which correspond to the circumferential radius of the infusion bottle and infusion belt made of glass or plastic, and are divided into small, medium, large and extra large.

[0030] In the above technology, when the clamping member is driven to slide upward, the opening and closing control portion decreases as the width of the constriction groove portion 11 decreases. At this time, the opening of the clamping portion will increase, and the infusion bottle will be aligned with the appropriate retention hole 21. The opening and closing control portion is driven to slide downward again. At this time, the opening and closing control portion returns to the vertical rod 1 and exits the constriction groove portion 11. At this time, the clamping portion will clamp the infusion bottle. At this time, according to the position of the retention hole 21 clamped on the bottleneck of the infusion bottle, the position of the clamping slot 3 is modified so that the clamping slot 31 is coaxial with the retention hole 21. In this way, the infusion set and the infusion tube are clamped, thereby preventing the infusion tube from detaching from the infusion bag.

An equidistant spring 4 is provided in the waist groove, and the equidistant spring 4 is fixedly connected to the guide member 22.

[0032] Specifically, in the embodiment, the isometric spring 4 is in the default state, and the isometric spring 4 pushes the guide member 22 to remain Figure 1 In the state shown, the opening and closing control part is on the vertical rod 1. As the opening and closing control width increases, the opening of the clamping part will shrink, thereby achieving clamping.

[0033] As another embodiment further provided by the present invention, a second waist groove 12 is provided on the vertical rod 1 , and the slot member 3 is locked at any height of the vertical rod 1 by a locking screw 6 provided in the second waist groove 12 .

[0034] Specifically, the locking screw 6 in the embodiment is divided into a first part and a second part, combined with Figure 2 It can be seen that the first part and the second part are threadedly connected, thereby driving the slot member 3 to clamp on the vertical rod 1 to form a locking fixation.

[0035] As another embodiment further provided by the present invention, a third waist groove 32 is formed on the slot member 3 , and the third waist groove 32 cooperates with the locking screw 6 .

[0036] The first part and the second part are threadedly connected to drive the slot part 3 to move, thereby changing the position of the locking screw 6 in the third waist groove 32, thereby changing the radial length of the slot part 3, so that the slot part 3 can be adapted to the retention hole 21 in the small, medium, large and extra-large states.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
