sample collection bag

technical field

The utility model relates to the field of medical consumables, in particular to a sample collection bag.

Background technique

During surgery, it is usually necessary to collect case samples from the surgical area for subsequent testing. Most of the existing sample collection bags are pvc ziplock ziplock bags. After the samples are put into the bags, the sample fixative solution is added and sealed for preservation. At present, 10% neutral buffered formalin is often used as the sample fixative. The main component of the fixative is formaldehyde, which is volatile and has certain toxic and side effects on the human body. When collecting samples, there are often operational risks such as occupational exposure of sample collectors, incomplete sample fixation, and delay in sample collection due to the leakage of fixative and the difficulty in obtaining samples.

The medical disinfectant fully soaks the cotton ball, and then takes it out for disinfection. It has various functions, not only for sample collection and fixation, but also equipped with a disinfection bag, which is convenient to operate. .

Optionally, a heat-sealing ridge is formed between two adjacent bag bodies by heat-pressing, and the tearing part is located in the middle of the heat-sealing ridge, so as to avoid damage to the bag body when torn.

The beneficial effects of the present utility model are: in the sample collection bag provided by the present utility model, under the isolation effect of the brittle plug, the sample fixative liquid and the gauze cannot be mixed. The handle is separated from the base, and the sample fixative in the second bag enters the first bag through the flexible channel to infiltrate the gauze. In the whole process, the operator does not need to directly contact the sample fixative, thereby avoiding the problem of occupational exposure.
