Medical drip bottle structure

Abstract

The invention provides a medical drip bottle structure. The medical drip bottle structure comprises a rubber head glass stopper, a first gas permeable plate and a second gas permeable plate; the top inner side of a main bottle body is embedded with a main bottle plug; a dropper is mounted on the bottom of the main bottle plug in an embedding mode; the rubber head glass stopper is movably mounted on the top of the main bottle plug in an embedding mode; the inner side of the main bottle plug is also fixedly provided with a rotary positioning groove. The setting of the rubber head glass stopper is beneficial to prolong the service life of a rubber head. When a reagent is needed to be stored, the rubber head glass stopper is pulled up and rotated 180 degrees counterclockwise, at this time, through holes in the second gas permeable plate are separated from through holes in the first gas permeable plate, and the first gas permeable plate and the second gas permeable plate completely separatethe rubber head from the dropper, so that the internal reagent can be effectively prevented from volatilizing into the rubber head during a preservation process, the service life of the rubber head is prolonged, unnecessary trouble of frequently changing the rubber head is avoided and the cost of use is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a medical drop bottle structure. Background technique [0002] Dropping bottle is a container commonly used in the laboratory to hold a small amount of liquid medicine. It is generally composed of a cap-type frosted dropper with a rubber head and a narrow-mouth bottle with an inner frosted neck. In medical chemistry and other experiments, when using liquid chemistry When the dosage of medicine is very small each time, or when it is easy to cause danger, a drop bottle is often used to contain the solution. Usually, liquid acid-base indicators are used in a drop bottle. [0003] For example, the patent application number 201410396123.1 discloses a sealed drop bottle, including a drop bottle and a test tube. The drop bottle and the test tube are made of glass, and the drop bottle and the test tube are used in conjunction. There is a capsule, the lower part of which is set a...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a medical drop bottle structure to solve the problem that most of the existing medical drop bottles are glass bottles. When some corrosive substances are placed in the reagent bottle for a long time, these substances may evaporate due to The effect is from the dropper to the top rubber head, and then these substances may continuously corrode the top rubber head. This will cause the rubber head to age, gradually produce cracks and reduce the sealing performance, and it may be directly damaged during use. Cause the glue head to fall off. Although the glue head of some dropper bottles is equipped with some anti-shedding structures, it still cannot prevent the glue head from corroding too quickly. Therefore, the replacement of the glue head is inevitable, which increases the difficulty of use and the cost of use.
