Description
Technical Field
The invention belongs to the technical field of medical care instruments, relates to an ampoule bottle opener, and particularly relates to a contact-free automatic ampoule bottle opener for injection injections for medical care.
Background
An ampoule is a sealed vial, which is commonly used for storing drugs, vaccines or serum for injection. The ampoule bottle is fired by a glass tube and is widely used for containing injection preparations. The ampoule bottle 1 comprises a nipple 11 and a bottle body 12, the joint of the two parts is a bottle neck 13, the nipple 11 and the bottle body 12 enclose a sealed container, and a liquid medicine 14 is contained in the sealed container. Before opening, a scratch is cut on the bottle neck 13 by a grinding wheel, the nipple 11 is upwards, so that the liquid medicine 14 completely flows into the bottle body 12, and then the bottle neck 13 is broken off, or the nipple 11 is knocked off by a blunt instrument.
Such problems often occur when removing the teat 11 if mishandled, or if the ampoule 1 is manufactured with defects. For example, the manually cut scratches are not connected end to form a spiral open loop, so that glass fragments are easily generated near the end to end when the nipple 11 is knocked off, and the glass fragments fall into the liquid medicine 14 to cause pollution. The bottle body 12 or the nipple 11 is sometimes knocked down, causing injury to medical staff or possible contamination by dropping glass fragments into the liquid medicine.
At present, a safe bottle opener is also available in the market, but the existing bottle opener can only open one ampoule bottle at a time, under the new crown pneumonia emergency epidemic situation of 2020, patients needing to be nursed get the same illness, the same injection medicine is used, medical staff need to open hundreds of or even more of the same ampoule bottles every day, and the working efficiency is low; and, the bottle opening step is loaded down with trivial details during actual operation, further reduces work efficiency. The prior bottle opener mechanically fixes the bottle body 12, the rotating mechanism drives the grinding wheel to perform circular cutting for a circle at the position of the bottle neck 13, then the nipple 11 is knocked off by a blunt instrument, the force applied to the bottle neck 13 by the grinding wheel is not uniform along the circumferential direction, the force applied to some places is small, the possible scratches are shallow, the nipple 11 is knocked off without fracture along the shallow scratches, so that glass fragments are easily generated, the force applied to some places is large, the ampoule bottle can be crushed, and the liquid medicine is scattered to cause waste.
