Abstract
Description
Technical Field
[0001] The utility model relates to a sputum sample collection box, in particular to a sputum sample collection box, belonging to the technical field of medical devices. Background Art
[0002] Due to reasons such as personal physique, immune status, seasonal alternation, and external environmental pollution, the number of people infected with respiratory diseases is increasing; lower respiratory tract infections rank fourth among the top 10 leading causes of death globally newly released by the World Health Organization. The diagnosis and treatment of respiratory infections mostly require collecting sputum from patients. The box used for collecting sputum in clinical trials consists of a sputum box body and a box cover. The patient directly twists open the box cover to collect sputum. Because the opening of the sputum box body is large, it is easy to cause pollution during the collection process due to splashing and other reasons. Since the sputum box body and the box cover are simply twisted on, it is necessary to wrap a sealing film for sealing. During the transportation of the sample, the sputum box is prone to sample leakage or seepage at the twist cover interface, making the sample extremely prone to pollution and bringing foreign bacteria, increasing the difficulty for subsequent metagenomic experiments and data analysis of pathogenic bacteria.
[0003] During the experiment, it is necessary to twist open the sputum box cover to add liquefying reagent. The sputum attached to the box cover and the sputum seeping out around it are likely to cause secondary pollution in the biological safety cabinet; to ensure that the seeping sputum does not pollute the experimental equipment, it is necessary to wrap the sealing film as a whole after adding the liquefying reagent, resulting in an unclear view of the liquefaction degree of the sputum, increasing the difficulty of the experiment. There is a prior patent for a funnel-shaped sputum collection box. In the patent with the authorization number CN215607790U, the diameter of the sputum collection inlet is sized to fit the patient's mouth size, and the sputum is collected in a mostly closed manner. The inner surface of the funnel body is smooth and has low adsorption, making it easy for the sputum to enter the sputum box body through the funnel; the diameter of the sputum collection outlet is relatively large, avoiding the sputum getting stuck on the funnel and not passing through easily due to its high viscosity and large chunks. This structure is simple and integrated, with strong sealing performance and can effectively prevent sputum leakage.
[0004] However, the sputum collection box in the patent with the authorization number CN215607790U is arranged in a conical structure, resulting in a small contact area between the bottom of the sputum collection box and the contact surface. As a result, the sputum collection box is unstable when placed, and it is prone to tipping over during the process of sending for inspection, causing the sputum inside the sputum collection box to adhere to the sputum collection cover. When opening the sputum collection cover, the sputum adhering to the sputum collection cover is likely to adhere to the operator's hand or the equipment for taking, resulting in pollution and seriously affecting the hygiene. For this reason, we propose a sputum sample collection box. Summary of the Utility Model
