Embodiment

[0045] as attached figure 1 to the attached Figure 9 shown:

[0046] The present invention provides a medical tube-free superficial vein indwelling needle, comprising a first installation sleeve 1;

[0047] The first installation sleeve 1 includes a first needle 101. The first needle 101 is located outside the first installation sleeve 1. The first needle 101 is used to pierce the skin of a patient. There are two outer sides of the first installation sleeve 1. There are two locking rings, the inner side of the second installation sleeve 501 is provided with two clamping grooves, the clamping grooves are clamped on the outer side of the locking ring, and the locking ring locks the second installation sleeve 501 on the outer side of the first installation sleeve 1, thereby Make the first installation sleeve 1 and the connection structure 5 form a whole;

[0048] The reinforcement seat 2 is clamped on the outer side of the first installation sleeve 1, the reinforcement seat 2...

Abstract

The invention provides a medical tube-sealing-free superficial vein indwelling needle, relates to the technical field of indwelling needles, and solves the problems that a tube of an indwelling needle is manually sealed, a needle head is bent and deformed, and medical personnel need to operate a flow regulator to seal an infusion tube. The first mounting sleeve comprises a first needle head, and the first needle head is arranged on the outer side of the first mounting sleeve; the reinforcing seat is clamped on the outer side of the first mounting sleeve, and the reinforcing seat is provided with a reinforcing ring; the two positioning plates are connected to the outer side of the first mounting sleeve in a clamped mode, and the two positioning plates are of a butterfly-shaped structure. The first sealing plug and the second sealing plug are punctured through the second needle head, so that the first sealing plug is communicated with the second sealing plug, the infusion tube is matched with the sliding seat, so that the second needle head effectively punctures the first sealing plug, and the sliding seat is elastically arranged, so that the first sealing plug is effectively punctured. Therefore, the first sealing plug can be flexibly switched between sealing and through.

Description

technical field [0001] The invention belongs to the technical field of indwelling needles, and more particularly, particularly relates to a medical tube-free superficial vein indwelling needle. Background technique [0002] The use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture in children, facilitate clinical medication, rescue medication for emergency and critically ill patients, and reduce the workload of nurses. Therefore, intravenous indwelling needles are widely used in clinical practice. In the process of using the medical indwelling needle, it is necessary to seal the tube. [0003] Based on the above, the existing superficial vein indwelling needle requires medical personnel to manually seal the tube of the indwelling needle. The tube sealing operation is troublesome, and the tube sealing procedure is cumbersome, increasing the labor force of medical personnel, and the external force of the needle hand will cause the...
