Safe self-destruction type vaccine injector

Abstract

The invention discloses a safe self-destroying vaccine syringe, which is characterized in that the side wall of a rod body at the end part of a core rod is provided with a transverse gap which is communicated with a longitudinal gap at the rod body of the end part of the core rod; the transverse gap is matched with the longitudinal gap; a needle consists of an upper hub and a lower hub which are sleeved with each other; an inner cavity of the lower hub is hollow; the lower hub is of a cylindrical structure; and the inner wall of the lower hub relative to the other end opening for mounting the upper needle stand is provided with a convex rid of the lower hub. The safe self-destroying vaccine syringe has the advantages that the whole vaccine syringe has a reasonable structure, completely accords with various international standards, controls liquid medicine accurately, can achieve high degree automatic mass production during assembling, effectively improves production efficiency, reduces manufacturing cost, has high working stability in actual use experiments, can effectively prevent the syringe from accidentally injuring medical staff and other correlative staff during operation, and also puts an end to the secondary recycle of a disposable vaccine syringe.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a safe self-destruction vaccine syringe, and in particular to its mechanical connection structure. Background technique: [0002] In order to prevent the needle tube of the disposable syringe from accidentally injuring medical personnel again after use, causing unnecessary medical accidents, disposable safety self-destructing syringes are widely used. The existing safety self-destructing syringe structure has the following disadvantages: 1. Product structure comparison It is complex and requires many parts, which increases the manufacturing cost of the product; 2. There are many parts in the product, which leads to cumbersome assembly procedures, and even the design structure of some products cannot realize mass production at all; 3. Existing security The dimensional error generated when the syringe parts are demolded is large, resulting in a high error rate in the actua...
