Breaker with function of vertical stress decomposing

Abstract

The invention discloses a breaker with a function of vertical stress decomposing. The breaker comprises a guide portion. The guide portion is internally provided with a passage; the passage having a turn is divided two segments by the turn; one segment is provided with an entry in the surface of the guide portion; the length from the turn to the entry is larger than the height of a nipple of an ampule and that of the ampule. With the breaker, a medical worker can break the ampule just by directly inserting the ampule into the entry of the breaker in the height-wise direction and applying force in the same direction; during use of the breaker, resultant force borne by the ampule is from the height-wise direction, the stress is decomposed into breaking force whereby the nipple is broken and recoiling force deviating to the horizontal direction, the breaking process is stable and basically free of vibration, and transverse vibration in the traditional breaking process is avoided. The process of using the breaker is free of flying of broken glass and splashing of liquid medicines, the risks that foreign matters are mixed in the liquid medicines and the liquid medicines are mixed during the opening process of the ampules are decreased, and safety of medical staff is guaranteed effectively.

Description

Technical field [0001] The invention relates to a medical appliance, in particular to an ampoule breaker. Background technique [0002] Ampoule, a sealed vial made of high-quality thin glass, is often used to store injection drugs, vaccines, serum, etc. The capacity of the ampoule is generally 1-25ml. [0003] In the prior art, all ampoules consist of a bottle body and a nipple, and a recessed bottleneck is formed between the nipple and the bottle body. [0004] At present, there are two main ways to use ampoules: the first is to pinch the nipple with your right hand, press the red dot on the bottle with your thumb, and pinch the bottle with your left hand. Use the recessed neck as a force point to pull the nipple from the bottle The body is broken, but this method is easy to scratch the hand of the nurse; the other is to scratch the neck of the ampoule with a grinding wheel for a week or a few more times with the grinding wheel, and then break it by hand or knock off the ampoule w...

Problems solved by technology

[0004] At present, there are two main ways to use the ampoule: the first is to pinch the nipple with the right hand, press the red dot on the bottle with the thumb, pinch the body of the bottle with the left hand, and use the concave neck of the bottle as the point of force to lift the nipple out of the bottle. The body is broken off, but this method is easy to scratch the hands of the nurse; the other is to scratch the neck of the ampoule bottle with a grinding wheel for a week or a few times with a grinding wheel, and then break it by hand or knock off the neck of the ampoule bottle with something. Nipples, although this method reduces the chance of scratching hands, there are still scratch accidents. Glass slag is easy to be generated when knocking with things. The broken glass slag may fall into the bottle body or splash outward. Not conducive to the protection of medical staff
