Disposable specimen collecting and inoculating device

Abstract

The invention discloses a disposable specimen collecting and inoculating device. The disposable specimen collecting and inoculating device comprises a collecting container and a sealing cover used for sealing the container, wherein an inner sleeve is fixed in the center of the inner side surface of the sealing cover; the bottom of the inner sleeve is fixed with an inoculating ring and a cotton swab capable of moving up and down in the sleeve; a limiting bracket for limiting position of the cotton swab is arranged on the tail part of the cotton swab; a clamping ring which is matched with the limiting bracket and plays a position limiting role is arranged on the inner wall of the hollow tube; the tail end of the limiting bracket is connected with a traction wire which is used for pulling the limiting bracket to cross the limiting ring for enabling the cotton swab to be retracted into the hollow tube; after penetrating through the sealing cover, the traction wire is connected with a pulling ring used for traction operation. According to the disposable specimen collecting and inoculating device disclosed by the invention, the specimen collecting, inoculating and drawing are completed by one step, and the disposable specimen collecting and inoculating device is discarded after being used, so that a process of heating the inoculating ring on an alcohol lamp till red to realize sterilizing is cancelled, and therefore, not only is crossed pollution avoided, but also time is saved and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a disposable specimen collection and inoculator. Background technique [0002] Clinical examination is the qualitative or quantitative analysis of various samples of blood, body fluids, secretions, excretions and sheds of patients, using experimental methods such as physics, chemistry and biology, in order to obtain information that reflects the functional state of the body, Objective data of pathological changes or etiology, etc. Therefore, clinical testing is very important for the later treatment of patients and the selection of drugs. [0003] Clinically, in the process of specimen inoculation, it is necessary to dip the specimen first, and then inoculate it on the culture plate. In order to obtain clear and distinct colonies, it is usually necessary to use an inoculation loop to streak the inoculation. Before inoculation, the inoculation loop should be burned red...
