Sputum cup

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a sputum cup. The sputum cup comprises a cup body and a cup cover, a cup mouth is arranged on the cup body, the cup mouth is located on the side wall of the cup body, the cup cover is in threaded connection with a cup mouth thread, the top of the cup cover is provided with an L-shaped smear groove, a vertical section of the smear groove is provided with a sliding block and a slide fixing device which is used for placing a slide, a wedge-shaped block is slidably connected with a horizontal section of the smear groove, one end of the slide fixing device abuts the end, away from the elastic member, of the sliding block, and the other end of the slide fixing device abuts an oblique surface of the wedge-shaped block; a smear tube is arranged in the cup cover, the smear tube is communicated with the smear groove and the cup mouth, a pressing plate which is used for tightly pressed the slide fixing device is included, and the pressing plate is hinged to the top of the cup cover. By means of the sputum cup, automatic smearing can be completed in the centrifugal process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sputum cup. Background technique [0002] Sputum is the secretion produced by the trachea, bronchi, and alveoli. Therefore, clinically, sputum detection is often used to assist in the diagnosis of certain respiratory diseases. Before the sputum test, the sputum needs to be collected and stored. At present, disposable sterile test tubes are often used to collect and store the sputum. However, for patients with pulmonary tuberculosis, inspectors need to digest the sputum samples before performing sputum smears or sputum culture. It is easy to generate aerosol when covering the lid, which will pollute the inspection environment and inspection personnel, and there is a risk of spreading diseases. [0003] In order to avoid the spread of disease caused by the aerosol overflow due to the addition of digestive juices, the sputum specimen indwelling device is improved. For ex...

Problems solved by technology

[0004] Because the digestive juice in the bottle cap is preloaded in advance, the dosage of the digestive juice is fixed, while the sputum in the bottle is added by the inspector, and the dosage is not fixed. Exposure, if the dose of digestive juice is too small, insufficient digestion will lead to insufficient exposure of pathogenic bacteria, if the dose of digestive juice is too high, excessive digestion may affect the test results of subsequent tests

[0005] The process of detecting sputum includes the acquisition of sputum samples, digestion, centrifugation, smear and inspection. After digestion, the sputum samples need to enter the centrifuge device for centrifugation. After the centrifugation, the sputum samples will be made into smears. Most of the existing smear operations are inspectors manually taking out sputum samples and applying them on slides. Aerosols are likely to be generated during the whole process from opening the bottle cap to applying the slides. Closer distance and prolonged contact increase the risk of disease transmission
