In order that the above-described aspects may be better understood, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

Fig. 1 to 3 illustrate a puncture needle 100 fixing device for preventing accidental withdrawal according to an embodiment of the present utility model, comprising: the fixing plate 1, the top surface of the fixing plate 1 is provided with a stop block 11; a through hole 12 is also arranged, and the through hole 12 passes through the fixed plate 1 and the stop block 11; a sliding groove 13 for sliding the side wings of the puncture needle 100 in is formed between the stop block 11 and the fixed plate 1, and the width of the sliding groove 13 is larger than that of the perforation 12; a plurality of clamping claws 2 are movably arranged at the periphery of the fixed plate 1; when the puncture needle 100 is used, the puncture needle 100 passes through the through hole, the puncture needle 100 is provided with the side wing, the side wing can also play a role similar to a handle except for controlling the penetration depth of the puncture needle 100 in use, but the side wing and the puncture needle 100 are integrally formed and are smaller and smoother, the side wing can not be pulled out when the side wing is pulled out frequently, the embarrassing condition that the side wing can not be inserted when the side wing is inserted is caused to be smaller, the side wing of the puncture needle 100 is directly related, the width direction of the fixing plate 1 of the puncture needle 100 is the same as the length direction of the puncture hole 12 when the puncture needle 100 penetrates, the side wing can be put into the puncture needle, the puncture needle 100 is rotated by 90 degrees after passing through the puncture hole 12 and slides into the chute 13, and the side wing forms a temporary locking structure through the combined action of the stop block 11 and the fixing plate 1, so that the area of the side wing is temporarily enlarged. The puncture needle 100 is inserted when in use, and the fixing plate 1 also provides a basis for the arrangement of the clamping claws 2.

Optionally, the fixing plate 1 is circular, and the clamping claws 2 are arranged in four pairs and symmetrically arranged around the circle center of the fixing plate 1. The fixing plate 1 can be polygonal, but the round shape is most convenient to process and operate, the number of the clamping claws 2 can be three or five, when three, the cost is lower, when five, the density is high, the protection effect can be achieved when the needle is pulled out, and the hand of an operator is prevented from being scratched when the needle is pulled out in an out-of-control manner.

Optionally, the length of the stop 11 is set along the length direction of the through hole 12, and the chute 13 is set correspondingly. The advantage of this is that it is easy to process.

A clamping claw 2, one end of which is rotatably connected with the fixed plate 1, and the other end of which forms a clamping end 21 which is convenient to clamp into the neck of the infusion bottle 200; the purpose of the holding jaw 2 is to grasp the fixing plate 1 together with the puncture needle 100 at the bottleneck of the infusion, but it is obviously not enough to rely on the holding jaw 2 alone, and the elastic member provided at the outer ring of the holding jaw 2 can tighten the holding jaw 2 so as to grasp the bottleneck of the infusion bottle 200, so that the holding jaw 2 does not pull out the puncture needle 100 when the puncture needle 100 is pulled by an external force.

Elastic fixing member 3: the clamping jaw 2 is sleeved outside and can move up and down along the clamping jaw 2. Alternatively, the elastic fixing member 3 is a rubber ring. Optionally, the clamping jaw 2 forms a recess into which the elastic fixing ring is snapped. Alternatively, the clamping jaw 2 is formed by bending a stainless steel wire. The idea of designing the elastic element to keep it closed by means of a radial restraining force on the clamping jaw 2, whereas the elastic fixing element 3 may be a rubber ring, is that if lost in use, a substitute, such as a rubber band for binding hair, may be easily found. In addition, a concave is arranged on the clamping claw 2, so that the elastic fixing piece 3 can not move up and down conveniently, and the clamping claw is fixed more firmly.
