Technical Field
The utility model relates to the technical field of medical appliances, in particular to a disposable double-chamber sample collecting pipe.
Background
In clinical applications, tissue specimens often need to be preserved, so that the integrity of the tissue specimens is ensured, the tissue specimens are convenient to store and transport, and the subsequent detection operations including PCR, immunohistochemistry and the like are convenient for medical inspectors to perform. In general, a tissue specimen is stored by being placed in a specimen storage solution, and a formalin fixing solution, a virus inactivating solution, and the like are common specimen storage solutions. Taking formalin fixing liquid as an example, formaldehyde in the formalin fixing liquid reacts with amino groups in proteins in a tissue specimen to solidify the proteins, so that antigenicity and microstructure of the tissues are well preserved, and the formalin fixing liquid has strong permeability and good fixing effect and can meet detection works such as conventional HE (human immunodeficiency syndrome) and immunohistochemistry, in-situ hybridization and the like.
Present sample preservation liquid is deposited in the middle of ordinary plastic bottle, when needs use sample preservation liquid to preserve the tissue specimen, need open the container of depositing sample preservation liquid and put into the sample preservation liquid with the tissue specimen in the middle of to preserve the tissue specimen. However, most specimen preservation solutions have volatile and pungent odors, and when a tissue specimen is placed in the tissue specimen by opening a cover, the specimen preservation solutions may overflow due to improper operation, which may adversely affect human bodies and the environment.
Firstly, the specimen preservation solution generally has a special pungent odor, so when an operator exposes the specimen preservation solution to the air, the pungent odor of the specimen preservation solution greatly influences the operation experience of the operator; secondly, when the operator places the tissue specimen in the specimen preservation solution, the operation difficulty is high, the overflow phenomenon easily occurs, and volatile toxic components contained in the specimen preservation solution threaten the health of the human body and pollute the environment. Therefore, the current operation mode makes it extremely difficult for patients or non-professionals to collect specimens at home, and increases the workload and work risk of professionals.
For virus inactivation liquid, the container used at present makes the possibility of leakage of the inactivation liquid far higher than that of the specimen collector, and needs to be operated by professional personnel. When the specimen collector is used, a patient or other persons needing to use the specimen collector can operate the specimen collector by himself.
Besides, the device is suitable for mixing two liquids or solids and liquids when in use, for example, the currently used hair dye is divided into two containers, and the components in one container are required to be poured into the other container when in use.
