Description

Disposable specimen collection and inoculator

technical field

The utility model relates to the technical field of medical supplies, in particular to a disposable specimen collection and inoculator.

Background technique

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.

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 on the alcohol lamp for disinfection, and then the operation steps such as inoculation can be carried out. The specimen collection container used in the past was relatively deep. When extracting the specimen, the inoculation loop and even the handle must be extended into the collection container to obtain the specimen. The handle is contaminated by the specimen, and the handle is not easy to burn completely in the alcohol lamp. Red disinfection and sterilization, so the gloves of medical staff are also contaminated, which can easily cause cross-contamination between specimens. For samples such as sputum, because the sample is relatively thin, the amount of sample attached to the inoculation loop is very small when it is extracted with the inoculation loop, and it is difficult to complete the inoculation. At this time, it is necessary to use tools such as cotton swabs to extract the specimen first, and then use the inoculation loop to inoculate. This requires multiple access to instruments, resulting in cumbersome operations and low efficiency.

Utility model content

The purpose of this utility model is to solve the deficiency of the above-mentioned technical problems, and to provide a disposable specimen collection and inoculator which completes specimen collection and inoculation drawing at one time.

The technical solution adopted by the utility model for solving the above-mentioned technical problems is: a disposable sample retention and inoculation device, including a retention container and a sealing cover for sealing the container, and an inner casing is fixed in the center of the inner surface of the sealing cover, so The inner casing is divided into two parts along its radial direction, one part is fixed with an inoculation ring for marking inoculation at the bottom, and the other part is a hollow tube, and a device for dipping is arranged in the hollow tube which can move up and down in the hollow tube. The cotton swab of the sample; the tail of the cotton swab is provided with a limit bracket to limit the position of the cotton swab, and the inner wall of the hollow tube is provided with a snap ring that cooperates with the limit bracket to limit the position; The pulling wire is used to pull it over the snap ring so that the cotton swab retracts into the hollow tube, and the pulling wire passes through the sealing cover and is connected with the pulling ring for pulling operation.

When the cotton swab of the utility model stretches out from the hollow tube, the heads of the inoculation loop and the cotton swab are all close to the bottom of the storage container.

When the cotton swab of the utility model is retracted into the hollow tube, the distance from the head of the inoculation loop to the bottom of the storage container is smaller than the distance from the head of the cotton swab to the bottom of the storage container.

The space-limiting bracket described in the utility model is composed of two supporting parts connected in a V shape, and one end of the pulling wire has bifurcations connected with the two supporting parts respectively, and the two supporting parts of the space-limiting bracket can be pulled Under the pulling of the line, they move closer to each other, so that the limit bracket goes over the snap ring.

The beneficial effects of the utility model are: the utility model fixes the inoculation loop and the cotton swab on the sealing cover through the inner sleeve, so that the extraction of the specimen and the inoculation line can be completed at one time, and they can be discarded after use, eliminating the need to burn them on the alcohol lamp. The red inoculation loop is used to achieve the sterilization process, which not only avoids cross-contamination but also saves time and improves work efficiency; at the same time, the cotton swab can be moved through the pulling wire and pull ring in the inner sleeve, so that the cotton swab can extract the specimen and spread it on the culture plate. The traction line outside the sealing cover is pulled outward, and the cotton swab can be moved upwards and retracted into the inner sleeve so that the head of the cotton swab is higher than the head of the inoculation loop, so that the disposable inoculation loop can be used to dip the specimen on the culture plate and draw next to it. Line, convenient and fast; the utility model puts the head of the inoculation loop and the cotton swab close to the bottom of the storage container, so as to avoid the inability to take the specimen due to too few specimens or the liquid level is too low, and the operation is convenient and simple.
