Description

Technical Field

[0001] The utility model relates to an infusion set fixer and belongs to the technical field of medical equipment. Background Art

[0002] Intravenous infusion therapy is a highly professional auxiliary treatment method, which is widely used in clinical treatment in my country. During infusion, awake patients turn over, get out of bed to defecate, and other activities; patients with poor consciousness and hyperactive children with weak self-control often pull the infusion set out of the bottle stopper, and the infusion set needs to be replaced every time, resulting in a waste of liquid medicine, consumables and nursing manpower, and there are certain safety hazards. Some psychiatric patients have their infusion set fall off due to restlessness, or because of the texture and elasticity of the rubber stopper of the infusion bottle, the needle entering the bottle slowly rebounds out, and only a small part of the needle contacts the liquid, and the air and liquid tip enter the infusion tube. If it is not discovered in time, it may lead to accidents such as air embolism, which seriously threatens the patient's life. Psychiatric patients also suffer from self-harm, and infusion sets have become one of the inevitable dangerous goods. To this end, the industry has successively developed a variety of related equipment. For example, the Chinese utility model patent with authorization announcement number CN210904377U discloses a fixing clamp for fixing an infusion pump, and specifically discloses a fixing block, one side of the fixing block is provided with an infusion pump body, the circumference of the infusion pump body is provided with a protrusion, the bottom of the fixing block contacts the surface of the protrusion, a first slide groove is opened inside one end of the fixing block, a first slider is slidably arranged inside the first slide groove, a positioning rod is fixedly arranged on the top of the first slider, a rotating shaft is fixedly arranged on the positioning rod, a hook is rotatably arranged on the circumference of the rotating shaft, a screw is rotatably connected inside the first slider, and the screw is threadedly connected to the fixing block d, a second slide groove is opened inside the other end of the fixing block, a partition is fixedly arranged in the second slide groove, and a second slider is slidably arranged on one side of the partition. However, this solution requires pressing the end of the hook to open it when the infusion set body is connected to the infusion bag, and when the infusion bag is large, the hook cannot be clamped at the open position due to insufficient opening angle; in addition, the distance between the hook and the fixed block needs to be achieved by turning the screw, which is complicated to operate and prolongs the operation time of medical staff. Utility Model Content

[0003] The purpose of the utility model is to provide an infusion set fixer, which can effectively fix the infusion set to the bottom cover of the infusion bag, thereby preventing the infusion set from loosening, leaking or falling off.

[0007] In the aforementioned infusion set holder, a first convex strip is provided on the upper part of the L-shaped rod toward the outer end; a second convex strip is provided at the bottom end of the vertical groove, and the second convex strip overlaps with the first convex strip in the horizontal direction.

[0008] In the aforementioned infusion set holder, the diameter of the first holding ring is greater than the diameter of the second holding ring.

[0009] In the aforementioned infusion set holder, the first holding ring and the second holding ring are located on the same side of the connecting rod.

[0010] In the aforementioned infusion set holder, the first holding ring, the second holding ring, the connecting rod and the extension mechanism are all made of plastic.

[0011] The aforementioned infusion set holder, the first connecting buckle and the second connecting buckle are both provided with a snapping mechanism, the snapping mechanism includes a second through hole arranged on the first locking ear and the second locking ear on one side, and the first locking ear and the second locking ear on the other side are respectively provided with a second clamping column, and the second clamping column faces the second through hole.

[0014] 1. After the needle of the infusion set is inserted into the bottom cover step of the infusion bag, the first holding ring is used to hold the bottom cover step of the infusion bag through the first opening, and the second holding ring is used to hold the sleeve of the infusion set through the second opening. Then, the distance between the first holding ring and the second holding ring is adjusted by moving the L-shaped rod, so that the lower end of the first holding ring is against the bottom cover step, and the upper end of the second holding ring is against the limit ring, so as to ensure that the infusion set and the infusion bag can be tightly connected. After that, the first locking ear and the second locking ear are contracted inwardly through the first connecting buckle and the second connecting buckle, so that the first holding ring and the second holding ring can better hold the infusion set and the infusion bag.

[0015] 2. The L-shaped rod of the utility model moves up and down in the vertical groove to adjust the distance between the first holding ring and the second holding ring. After the distance is determined, the L-shaped rod is fixed in a suitable position through the first through hole and the first clamping column. When the patient suddenly exerts force to separate the first through hole and the first clamping column so that the L-shaped rod slides off, the second convex strip at the bottom of the vertical groove will clamp the first convex strip on the L-shaped block to prevent the L-shaped rod from separating, further ensuring that the infusion set can still be connected to the infusion bag under extreme conditions, and avoiding accidents such as air embolism caused by the needle falling off and air entering the infusion set.

[0025] How it works

[0026] After the needle 21 of the infusion set 20 is inserted into the bottom cover step 31 of the infusion bag 30, the first holding ring 1 is used to hold the bottom cover step 31 of the infusion bag 30 through the first opening 2, and the second holding ring 4 is used to hold the sleeve 23 of the infusion set 20 through the second opening 5. Then, the distance between the first holding ring 1 and the second holding ring 4 is adjusted by the extension mechanism, so that the lower end of the first holding ring 1 is against the bottom cover step 31, and the upper end of the second holding ring 4 is against the limit ring 22, so as to ensure that the infusion set 20 and the infusion bag 30 can be tightly connected. After that, the first locking ear 6 and the second locking ear 8 are contracted inwardly through the first connecting buckle 7 and the second connecting buckle 9, so that the first holding ring 1 and the second holding ring 4 can better hold the infusion set and the infusion bag.
