Problems solved by technology

[0002] The drug extractor is a tool used to transfer liquid drugs out of the container bottle. For volatile drugs, they are generally sealed and stored. When extracting, the container cap needs to be removed and sucked. Air will enter the container bottle, and due to the instability of the volatile drug, it is easily oxidized, resulting in a certain change in the composition of the drug and affecting the use. On the other hand, during the inhalation process, the container bottle is in an open state, A certain amount of volatilization of the drug will occur

Embodiment 1

[0043] see figure 1 , a self-overfill-proof extractor for volatile medicines, comprising an extractor body 1, a piston 2 is interference-fitted inside the extractor body 1, and the lower end of the piston 2 located in the piston 2 is fixedly connected with a two-way containment bag 5, and the two-way containment bag Both the lower end surface of the 5 and the inner bottom of the extractor body 1 are coated with an adhesive layer. After the inert gas is squeezed out, the two-way container 5 is compressed and is in close contact with the inner bottom of the extractor body 1 through the adhesive layer, which facilitates Draw the medicine upwards. After drawing the medicine, continue to pull the piston 2 upwards to separate the two-way container 5 from the inner bottom of the extractor body 1, effectively avoiding the situation that the medicine is squeezed and leaked by accidentally touching the piston 2. The lower end of the two-way container 5 The drug suction tube 4 is fixedly...

Abstract

The invention discloses a self-spill-proof extractor for volatile drugs, and belongs to the field of extractors. The self-spill-proof extractor for the volatile drugs is characterized in that through the arrangement of a bidirectional containing bag and a turning notch piece, when the drugs are extracted, a drug suction pipe is firstly inserted into an opening part of a container for containing the drugs, then inert gas is extruded into a container bottle, on one hand, the empty space in the container after the medicine is sucked can be effectively filled, then volatilization of the medicine is effectively restrained, on the other hand, the inert gas can effectively protect unstable volatile gas from being prone to oxidation reaction with air, when the medicine is sucked, the turning notch piece reversely deforms, the medicine enters the two-way containing bag, in addition, under the action of an outer isolation bag, the outside and the extraction opening in the container opening can be effectively isolated, and then medicine is effectively prevented from being volatilized to the outside during medicine extraction.

Description

technical field [0001] The invention relates to the field of extractors, in particular to a self-overflow-proof extractor for volatile medicines. Background technique [0002] The drug extractor is a tool used to transfer liquid drugs out of the container bottle. For volatile drugs, they are generally sealed and stored. When extracting, the container cap needs to be removed and sucked. Air will enter the container bottle, and due to the instability of the volatile drug, it is easily oxidized, resulting in a certain change in the composition of the drug and affecting the use. On the other hand, during the inhalation process, the container bottle is in an open state, The medicine will volatilize to a certain extent. Contents of the invention [0003] 1. Technical problems to be solved [0004] Aiming at the problems existing in the prior art, the object of the present invention is to provide a self-overflow-proof extractor for volatile medicines. Through the setting of the...
