[0002] The collection of throat swabs for respiratory infections is a medical procedure that obtains secretion samples by wiping the mucosal surface of the throat (oropharynx or nasopharynx). It is mainly used to detect pathogens (such as viruses, bacteria, etc.) that cause respiratory infections. It mainly uses sterile cotton swabs or synthetic fiber swabs to gently wipe the mucosal surface of the patient's throat (oropharynx or nasopharynx) to collect secretion samples containing pathogens.

[0003] Chinese patent CN111166391B discloses a pharyngeal swab collection device and a collection method thereof for reducing the risk of infection with the new coronavirus. The pharyngeal swab collection device includes a mask body and two hanging straps. The mask body is a transparent structure, and a through hole is provided in the mouth or nose covering area. The sides of the mask body are provided with at least one pressure relief channel for lateral pressure relief, and the pressure relief channel connects the patient's mouth and nose front cavity to the outside of the mask body laterally; the pharyngeal swab collection device also includes a swab socket, and the cover of the swab socket can fully cover the through hole to close the through hole; the swab socket is also provided with a clamping hole for the rod of the collection swab to pass through, and a close-fitting structure is formed between the rod of the collection swab and the inner wall of the clamping hole, and the collection swab can move forward and backward, rotate and swing on the clamping hole. When medical staff operate the pharyngeal swab collection device of the present invention, it will not cause positive infection to medical staff, reducing the risk of medical staff being infected.

[0004] The above technical solution sets a pressure relief channel to guide and discharge the airflow generated by the patient's sneeze or cough during swab collection, thereby avoiding the problem of the patient's cough or sneeze directly impacting the medical staff.

[0016] Compared with the prior art, the present invention provides a contact-free respiratory infection throat swab collection device, which has the following beneficial effects: 1. In the present invention, when sampling is performed, the collection swab is pushed into the transparent mask by the pushing block, so that the collection swab is sent into the oral cavity or nasal cavity of the patient, and then the patient is sampled by the collection swab. When the collection swab is driven to move by the pushing block, the circular plate is synchronously driven to move by the pushing block. When the circular plate moves to the initial position of the slider, the connecting component connects the slider with the circular plate. At this time, the slider follows the circular plate to move in the shell. After the sampling is completed, the pushing block moves in the opposite direction, thereby driving the collection swab to move out of the patient's oral cavity. When the pushing block moves in the opposite direction, the circular plate is also driven by the pushing block to move in the opposite direction. The movement of the circular plate drives the slider to move through the connecting component, and the movement of the slider drives the pushing component to operate. The pushing component operates to drive the cutting knife to move toward the collection swab and cut the collection swab, thereby achieving the effect of automatically cutting the collection swab after the collection is completed, thereby avoiding the problem that the collection swab needs to be manually broken after the collection is completed. 2. In the present invention, during the collection, the patient wears a transparent mask. When the patient has symptoms of sneezing and coughing due to the entry of the collection swab, the airflow generated by the sneezing and coughing is discharged from the transparent mask through the filtering mechanism. After the airflow enters the filtering mechanism, the filtering mechanism filters the pathogens and bacteria in the airflow, thereby avoiding the problem of poor infection. In addition, the filtering mechanism can also filter the air inhaled by the patient, further improving the practicality; 3. In the present invention, when collecting, the collection swab is pushed into the transparent mask by the pushing block. During this process, the pushing block moves the stretching reset spring and drives the circular plate to squeeze the squeezing spring. After the squeezing spring is squeezed to the maximum limit by the circular plate, the pushing block squeezes the connecting spring again. Then, when the patient sneezes and coughs, the pushing block is released. At this time, the pushing block quickly returns to its original position under the action of the reset spring, the squeezing spring and the connection, thereby avoiding the problem that the collection swab is in the patient's nasal cavity or oral cavity when the patient coughs and sneezes, thereby causing injury to the patient, thereby further improving the safety of use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a contact-free respiratory infection throat swab collection device.

A circular plate 6 is provided on the outer side of the push block 5. The collection swab 4 is used for sample collection. When the push block 5 moves, it can drive the collection swab 4 and the circular plate 6 to move into the transparent mask 1. A cutting mechanism 7 is also provided in the shell 2, and the cutting mechanism 7 is distributed on both sides of the shell 2. The cutting mechanism 7 includes a slider 71, a connecting component 72, a pushing component 73 and a cutting knife 74. The pushing component 73 is used to drive the cutting knife 74 to move toward the center line of the shell 2. When the pushing component 73 drives the circular plate 6 to move to the slider 71, the connecting component 72 can connect the slider 71 with the circular plate 6. When the slider 71 moves, the pushing component 73 drives the cutting knife 74 to cut the collection swab 4.

[0022] In the initial state, the collection swab 4 is on the inner side of the shell 2. When collection is needed, the user wears the transparent mask 1, and then the user pushes the push block 5. The push block 5 moves to drive the collection swab 4 and the circular plate 6 to move toward the transparent mask 1. Then the collection swab 4 is pushed into the transparent mask 1 by the push block 5, and then the patient is collected through the collection swab 4. In the process of the circular plate 6 moving toward the transparent mask 1, when the circular plate 6 moves to the opposite position of the slider 71, the slider 71 is connected to the circular plate 6 with the cooperation of the connecting component 72. At this time, the slider 71 moves toward the transparent mask 1 with the circular plate 6. After the collection is completed, the user pushes the push block 5 in the reverse direction. Similarly, the collection swab 4, the circular plate 6 and the slider 71 all move in the reverse direction. The slider 71 moves in the reverse direction. After moving, the pushing component 73 is driven to operate, and the pushing component 73 operates to push the cutting knife 74 in the cross-sectional direction of the collection swab 4. As the pushing block 5 continues to move, the pushing component 73 drives the cutting knife 74 to cut the collection swab 4 horizontally, so that after the collection of the patient is completed, the collection swab 4 can be automatically cut off, thereby avoiding the problem of manual processing. In addition, in the process of collecting the patient, once the patient sneezes or coughs, the droplets or aerosols generated by the sneeze or cough are discharged. The filtering mechanism 3 can filter the droplets or aerosols generated by the sneeze or cough, thereby avoiding the problem that some droplets and aerosols will fly out and affect the people on the side and rear.
