Separation type contact-free tissue preservation pot

Abstract

The invention discloses a separation type contact-free tissue preservation pot. The separation type contact-free tissue preservation pot comprises a main pot body, a liquid box located in the pot mainbody, a specimen box which sleeves an inner wall of the liquid box, and a cover which is in thread connection with the top of the pot main body, wherein the pot main body comprises a connecting pipe,a specimen box storage pipe, a first fixing ring and a liquid box storage pipe; outer threads are opened in an outer wall of the connecting pipe; the bottom of the connecting pipe is welded with thetop of the specimen box storage pipe; the first fixing ring is welded with the bottom of the specimen box storage pipe; the bottom of an inner side wall of the first fixing ring is welded with the topof an outer side wall of the liquid box storage pipe. The separation type contact-free tissue preservation pot disclosed by the invention is simple in structure, convenient to operate, low-cost and convenient for disposable use; a formalin solution is stored in the liquid box; the formalin solution is sealed through a sealing film, and a condition that an operator makes direct or indirect contactwith harmful substances is avoided; a filtering screen is used for separating a specimen and formalin, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tissue preservation jars, in particular to a separate contact-free tissue preservation jar. Background technique [0002] In medical and biological research work, it is usually necessary to cut and preserve biological tissues for easy storage and scientific research. Existing hospitals use ordinary sealed jars for tissue preservation, and the lid of the jar needs to be opened during operation. Malin solution is directly exposed to the air, and if it is not handled properly, it will come into direct contact with the operator. Direct contact with formalin can cause short-term irritation to the skin, eyes, mucous membranes, etc. Inhalation of formaldehyde gas or vapor in formalin liquid can cause coughing, nausea, severe vomiting, diarrhea and laryngitis. Formaldehyde is also a chronic toxin , Repeated or prolonged exposure can cause permanent respiratory damage and formaldehyde has been listed as a carcino...
