Embodiment 1

[0023] Such as Figure 1-4 , An anti-needle puncture scalp needle for an infusion tube, comprising a needle 1, a needle holder 2, a needle wing 3 and a tube 4. The needle wing 3 is fixedly installed on the outer surface of the needle holder 2, and the needle 1 is slidably installed On the inner wall of the needle seat 2, a transition tube 5 is provided between the hose 4 and the needle seat 2. The transition tube 5 is fixedly installed on the outer surface of the needle seat 2, and the hose 4 is fixedly installed on the transition tube 5. The end of the transition tube 5 away from the needle seat 2 is provided with a through hole 6. The end of the needle 1 located in the transition tube 5 is fixedly installed with a sealing slider 7, and the sealing slider 7 is slidably installed On the inner wall of the transition pipe 5, a number of magnetic blocks 8 evenly distributed in the circumferential direction are embedded in the corresponding surface of the sealing slider 7 in contac...

Embodiment 2

[0028] Such as Figure 5 The difference between this embodiment and embodiment 1 is that the needle 1 is fixedly installed at the end of the transition tube 5, and a protective sleeve 19 is slidably installed on the inner wall of the needle holder 2, and the protective sleeve 19 is sleeved on Outside the needle 1, the two ends of the protective sleeve 19 are respectively fixedly installed with a second sealing slider 20 and a limiting block 21. The second sealing slider 20 is slidably mounted on the inner wall of the transition pipe 5. The second sealing A number of magnetic blocks 8 evenly distributed in the circumferential direction are embedded in the corresponding surface of the sliding block 20 in contact with the transition tube 5, and a sliding sleeve on the outer surface of the hose 4 is provided with positioning components for limiting the position of the protective sleeve 19; A protective sleeve 19 is provided. Under the action of the positioning component, the protect...

Abstract

The invention discloses an anti-needlestick scalp needle for infusion tubes. The anti-needlestick scalp needle comprises a needle head, a needle seat, needle wings and a hose, a transition tube is arranged between the hose and the needle seat, a through hole is disposed at an end of the needle base away from the needle seat, a seal sliding block is fixedly installed at the end of the needle head and is slidably installed on the inner wall of the transition tube, a plurality of magnetic blocks evenly distributed along the circumferential direction are embedded to a corresponding surface of theseal sliding block in contact with the transition tube, and a positioning assembly for limiting the position of the needle head is slidably sleeved to an outer side of the hose. According to the invention, by setting the transition tube and the seal sliding block, and under the action of the positioning assembly, the seal sliding block is driven to move in the transition tube, and then the purposes that the scalp needle is stored in the transition tube when not used and is led out in use are realized, so that the scalp needle use state and the scalp needle protecting state are in an integratedstructure, and the circumstances of accidental falling and losing caused by use of an independent protecting sleeve are avoided.

Description

Technical field [0001] The invention belongs to the field of medical appliances, and in particular, relates to a scalp needle for an infusion tube that prevents needle stick injuries. Background technique [0002] A large number of domestic studies have shown that nurses are a high-risk occupational group of blood-borne diseases, and wounds caused by cuts and needle sticks are common on the hands of nurses. [0003] Since the current scalp needles for infusion tubes use independent needle sleeves, they are easy to fall and lose, which may cause accidental stabbing of nurses when arranging the infusion tube. Based on this, we propose a needle stick prevention method Scalp needle for infusion tube. Summary of the invention [0004] The purpose of the present invention is to provide a scalp needle for an infusion tube that is resistant to needle stick injuries, so as to solve the problems raised in the background art. [0005] In order to achieve the above objectives, the present inven...
