Description

Inoculating loop with smearing rod

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of medical appliances, in particular to transfering loop of stick is paintd in area.

[ background of the invention ]

In the field of microbiology, smear and inoculation experiments are often performed on clinical specimens to quickly identify and isolate pathogenic bacteria. At present, in clinic, a specimen smear is operated by using a smear stick, and specimen inoculation is operated by using an inoculating loop, namely, the specimen smear and the inoculation are completed by using independent medical appliances. For example, in the case of a sticky specimen such as sputum and feces, a medical worker needs to stick the specimen with a stick and smear it on a glass slide, and then pick the specimen with an inoculating loop and spread it on a solid medium for streaking and inoculating. The specimen smear and inoculation are operated by different tools, and the following problems exist:

(1) the alternate operation of the inoculating loop and the smearing rod causes waste of time and resources;

(2) the smearing rod and the inoculating loop can not be placed on the operation table-board after picking the specimen, and the operation is inconvenient.

In order to solve the problems, the invention of the chinese patent application CN 108753591A discloses an integrated anal detection and bacteria enrichment sampling tube, a method and a use thereof, and discloses a technical scheme of integrally sleeving an inoculating loop in a sampling rod. The smearing effect of the medium silica gel smearing rod for bacterial culture of Chinese utility model CN 204509334U can also be used for inoculation, but the problem that the medium silica gel smearing rod cannot be temporarily placed on an operation table top still exists.
