Document Type and Number:
WIPO Patent Application WO/2020/192268
Kind Code:
A1
Abstract:
A medical sub-primary bag capable of preventing formaldehyde leakage, comprising a primary bag for sealing and containing a specimen and a sub bag for sealing and containing a formalin solution. The sub bag is in communication with the primary bag by means of a pipe, and a switch device is provided on the pipe. When in use, a seal of the primary bag is opened, the specimen is placed into an inner bag of the primary bag, then the seal is pressed, and the switch is opened and the sub bag is lifted, such that the formaldehyde solution enters the primary bag by means of the external atmospheric pressure and the self-weight of the liquid, and the switch is closed, and the sub-primary bag is sent to a laboratory. In this process, the formaldehyde solution does not volatilize to the outside, preventing the formaldehyde solution from volatilizing and leaking to harm the human body, and also ensuring that the concentration of the formaldehyde solution is unchanged.
