Description

a sputum collector

technical field

The utility model relates to a medical appliance, in particular to a sputum collector.

Background technique

In hospital clinics, it is one of the commonly used inspection methods to find tumor cells and tuberculosis and other opportunistic pathogenic bacteria through sputum. At present, the sputum collectors in clinical use use circular flat-bottomed containers, or replace them with urine and stool containers. Since the inner bottom of this type of container is a flat-bottomed structure, the sputum is spread flat on the bottom and cannot be concentrated, resulting in Sputum cell components and pathogenic microorganisms are not easy to collect. At the same time, sputum will dry out after a long time, which will cause cells and pathogenic microorganisms to deform, crack or volatilize, which will reduce the detection rate. On the other hand, the container Large volume, poor sealing, inconvenient storage of sputum samples; clinical sputum collection is also carried out in laboratory bottles, requiring patients to cough sputum into the bottle, on the one hand, it is not convenient for patients to use because of the small mouth of the bottle, on the other hand On the one hand, when the bottle is opened and the sample is transferred during the sputum test, it is easy to cause sputum splash, which increases the risk of contamination and infection of medical staff.

Detailed ways

The utility model will be further described below in conjunction with specific examples. It should be understood that these examples are only used to illustrate the utility model and are not intended to limit the protection scope of the utility model.

As shown in Fig. 1, Fig. 4 and Fig. 5, the utility model provides one of a kind of sputum collector, which comprises top cover 1, collection funnel 3, sputum storage tube 4 from top to bottom, top cover 1 and collection funnel 3 is connected by thread, the collection funnel 3 is connected with the sputum storage tube 4 by thread, the sputum storage tube 4 is a liquefaction reaction tube, including the tube body 4-1 and the tube bottom 4-2 that penetrate up and down, and the inner cavity of the tube bottom is from top to bottom. The lower cross-sectional area decreases gradually, and the lower end of the tube bottom 4-2 is spherical. When in use, remove the top cover 1 and expectorate into the collection funnel 3. After sampling, add a liquefaction agent into the sputum collector. After the sample is placed in the liquefaction reaction tube 4, remove the collection funnel 3 and pass through the liquefaction reaction. The matching lid of the opening of the tube 4 is covered, sealed up, and sent for inspection. The collection funnel 3 is provided with a larger opening, which is convenient for patients to cough up sputum for sampling, safe and hygienic to use, and avoids polluting the outer wall of the container. The liquefaction reaction tube 4 includes a tube body 4-1 and a tube bottom 4-2 that penetrate up and down.
