Example Embodiment

[0024] The present invention will be further described below with reference to the drawings and embodiments.

[0025] Coaxial pull-out ampoule opening mechanism, consisting of right half sleeve 01, left half sleeve 02, sleeve liner 03, inner cylinder 04, pull block 05, pull strip 06, square hole 07, grinding wheel 08, slot 09, latch 10 , The elastic piece 11, the rotating shaft 12, the shaft cap 13, the inner cylinder liner 14, the outer cylinder 15, the convex ring 16, the limiting groove 17, the fixed piece 18, the teeth 19, the sliding groove 20 and the tooth groove 21.

[0026] Among them, the outer cylinder 15 is a cylinder with both upper and lower ends open, and an annular limiting groove 17 is provided on the inner side wall of the outer cylinder 15. A horizontal slot 09 is opened on the side wall at the upper end of the outer cylinder 15. The strip-shaped plug 10 passes through the slot 09 horizontally and forms a clearance fit relationship with the slot 09. The inner en...

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a coaxial pulling-type ampoule opening mechanism which is composed a right half sleeve, a left half sleeve, a sleeve liner, an inner cylinder, a pulling block, a pulling strip, a square hole, a grinding wheel, a plug groove, a plug pin, an elastic piece, a rotating shaft, a shaft cap, an inner cylinder liner, an outer cylinder, protruding rings, limiting grooves, a fixing piece, teeth, a sliding groove and a toothed groove. The cylindrical inner cylinder is located in the outer cylinder and is in clearance fit with the outer cylinder. The annular toothed groove is formed in the outer side wall of the upper end of the inner cylinder. The teeth evenly distributed along the circumference of the inner cylinder are arranged inside the toothed groove. The square hole in the pulling strip is matched with the teeth inside the toothed groove simultaneously. According to the coaxial pulling-type ampoule opening mechanism, a single closed scratch can be etched into the neck of an ampoule bottle only by the simple operation of pulling the pulling strip, operating efficiency is improved, and the purity of liquid medicine and the safety of medical workers are ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a coaxial pull-type ampoule opening mechanism. Background technique [0002] At present, when medical personnel open the ampoule, they usually use a grinding wheel to scratch around the neck of the ampoule, and then break the ampoule by hand. When scoring with an abrasive wheel, it is important to make a closed and single score because a single, closed score helps the ampoule neck to break in a single direction and form a clean break. Only in this way can the amount of glass shards be reduced as much as possible. However, medical personnel will draw a single, closed scratch on the ampoule with bare hands, which requires strong hands-on ability and more time, which reduces the efficiency of opening the ampoule. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a coaxial pull-type ampoule opening mecha...
