Problems solved by technology

[0003] However, in the prior art, the infusion needle at the end of the infusion tube is directly inserted into the sealing rubber plug of the infusion bag during infusion, but this connection method will cause the connection between the infusion tube and the infusion bag to be unstable. Or when there is poor contact with the sealing plug, the infusion tube will fall off from the infusion bag, thereby contaminating the puncture tube. At this time, the infusion tube must be replaced, resulting in low work efficiency for medical staff and increased medical costs for patients.

Embodiment 1

[0037] as Figure 1-4 As shown, the present embodiment provides an anti-shedding infusion tube, comprising a tube body 1, the above-described tube body 1 having a puncture tube 2, the above-described puncture tube 2 side wall is provided with an anti-shedding component, the above anti-shedding assembly comprises an operating ring 3, a lifting rod 4, an elastic member and an anti-shedding rod 5; The outer side wall of the piercing tube 2 is provided with a toroidal groove 21, the above operating ring 3 thread is connected to the inner bottom wall of the above-described annular groove 21, the above-described annular groove 21 is provided with a sliding blind hole 22 on the inner top wall, the above-described puncture tube 2 is provided with a sliding hole 23 on the side wall of the piercing tube 23, the above sliding hole 23 and the above-mentioned sliding blind hole 22 anti-release rod 5 seal sliding is provided on the above sliding hole 23, the above anti-release rod 5 near one end...

Embodiment 2

[0043] as Figure 1-4 As shown, the present embodiment on the basis of Example 1, the above-described puncture tube 2 outer wall sleeve is provided with an elastic protective sleeve 6.

[0044]In the present embodiment, the outer wall sleeve of the piercing tube 2 is provided with an elastic protective sleeve 6, the elastic protective sleeve 6 completely wraps the piercing tube 2 before use, so that the piercing tube 2 is exposed to the user's field of vision before use, so that even if the user's limbs move to the vicinity of the puncture tube 2, it will only come into contact with the elastic protective sleeve 6, and will not touch the tip of the puncture tube 2, thereby avoiding the user being punctured by the puncture tube 2 before using the puncture tube 2, ensuring that the user safely uses the puncture tube 2, Puncture tube 2 into the infusion tube or infusion bottle.

[0045] In some embodiments of the present embodiment, the above elastic protective sleeve 6 comprises an e...

Embodiment 3

[0049] as Figure 1-4 As shown, on the basis of some of the above embodiments, the outer side wall of the puncture tube 2 is provided with a barrier ring 7, the above barrier ring 7 is provided between the above-described annular groove 21 and the sliding hole 23, the barrier ring 7 is located in the above elastic protective sleeve 6, the above barrier ring 7 is connected to the above elastic protective sleeve 6.

[0050]In the present embodiment, the barrier ring 7 is offset with the elastic protective sleeve 6, so that the elastic protective sleeve 6 can be stably set on the outside of the piercing tube 2, when using the piercing tube 2, only need to make the elastic protective sleeve 6 relative to the blocking ring 7 relative to slide, so that the elastic sleeve 61 moves away from the direction of the puncture end of the puncture tube 2, and the elastic protective sleeve 6 can also be stably fixed; Moreover, after the puncture tube 2 punctures into the infusion bag or infusion b...

Abstract

The invention provides an anti-falling infusion tube, and relates to the technical field of medical instruments. An anti-falling infusion tube comprises a tube body, the tube body is provided with a puncture tube, an anti-falling assembly is arranged on the side wall of the puncture tube and comprises an operation ring, a lifting rod, an elastic piece and an anti-falling rod, an annular groove is formed in the outer side wall of the puncture tube, the operation ring is in threaded connection with the inner bottom wall of the annular groove, and a sliding blind hole is formed in the inner top wall of the annular groove; a sliding blind hole is formed in the side wall of the puncture tube, a sliding hole is formed in the side wall of the puncture tube and communicated with the sliding blind hole, an annular groove is formed in the upper end of the operation ring, the upper portion of the lifting rod is slidably arranged in the sliding blind hole, and the lower end of the lifting rod is slidably arranged in the annular groove. A second inclined surface matched with the first inclined surface is arranged at the upper end part of the lifting rod; the elastic piece is arranged between the inner wall of the sliding hole and the anti-falling rod; the infusion tube can effectively prevent the puncture tube from falling off from an infusion bag or an infusion bottle in use.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular, to an anti-shedding infusion tube. Background [0002] Infusion, or bulk injection, refers to a large dose of injection injected into the body by intravenous infusion, with a single administration of more than 100 ml. It is a branch of the injection, usually packaged in a glass or plastic infusion bottle or bag, without bacteriostatic agents. The drip rate is adjusted through the infusion device during use, and the drug is continuously and stably injected into the body. [0003] However, in the prior art, the infusion is the end of the infusion tube directly into the infusion bag of the sealing rubber plug, but this connection will lead to the connection between the infusion tube and the infusion bag is unstable, when the infusion tube is subjected to external force or poor contact with the sealing plug, it will cause the infusion tube to fall off from the infusion bag, ...
