Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of sputum pretreatment equipment, and more specifically, relates to a sputum homogenization, shaking, sampling integrated pretreatment equipment and a use method. Background Art
[0002] At present, sputum samples are mainly used for sputum cytology and respiratory pathogen detection in clinical practice. The existing detection method is that the patient spits sputum directly into the collection container, and then the tester opens the lid and adds dilution digestion fluid to the collection container to dilute the sputum into a homogenized test sample, then closes the lid and shakes it, and then opens the lid to absorb the sample. At present, sputum digestion mainly relies on manual operation, which is easy to cause the spread of respiratory diseases and mutual contamination of sputum samples, and the operation is cumbersome. Therefore, it is of great significance to propose a device or method for efficiently processing sputum for subsequent detection to improve work efficiency and staff safety.
[0003] In order to solve the above technical problems, Chinese invention patent CN112629940A discloses a sputum sampling detection device and its use method, the sputum sampling detection device includes a detection tube, a collection tube and a test paper; the detection tube is provided with a accommodating chamber, a sealing film and a test paper chamber; the sealing film divides the accommodating chamber into a collection tube accommodating portion and a diluent accommodating portion; the test paper chamber is located at the front side of the accommodating chamber, and a connecting channel is provided between the collection tube accommodating portion and the test paper chamber; the connecting channel is located above the sealing film; the diluent accommodating portion is filled with sputum diluent; the collection tube is detachably connected to the collection tube accommodating portion, and a membrane-penetrating structure is provided at the lower end of the collection tube, and the membrane-penetrating structure is used to pierce the sealing film; the test paper is arranged in the test paper chamber. The technical solution of the present application adopts a two-stage pressing design. After the sealing film is pierced, the sampling rod needs to be further pressed to allow the diluent to enter the test paper chamber, thereby effectively preventing the problem of misoperation.
[0004] The above patent scheme adopts a double-tube design to achieve an integrated processing effect of sampling, dilution and detection, but there are still the following technical problems: (1) After diluting the sputum, the scheme directly enters the test paper detection link, and the two processes are not fully shaken and left to stand, resulting in poor accuracy of the test results; (2) After vortex oscillation and standing, the sample is sucked into the nucleic acid extraction plate by the sample gun, and the nucleic acid detection method is adopted. Compared with the test paper method, the nucleic acid detection method of sputum is more accurate, but the above scheme cannot be transferred to the nucleic acid detection method. (3) Based on the standard operating procedures of the sputum nucleic acid detection method, a set of sputum pretreatment devices with integrated sputum homogenization, shaking and sampling should be designed to improve the overall operation efficiency.
