Description

Technical Field

[0001] The present invention relates to the technical field of throat swab sampling, and in particular to a throat swab collection cotton swab and a detection method. Background Art

[0002] Novel coronavirus pneumonia is an acute infectious pneumonia. The initial symptoms of patients with novel coronavirus pneumonia are mainly dry cough, fever, and fatigue, which gradually turn into dyspnea in the later stage, accompanied by the concentrated outbreak of multiple comprehensive diseases of the patients themselves. According to medical clinical observation, the incubation period of the virus is 1-14 days, and it is highly contagious during the incubation period. Therefore, how to quickly and accurately screen out the infected population has become the main means of controlling the spread of the epidemic. At present, the bacterial flora samples are collected from the patient's throat through swabs for analysis and judgment.

[0003] Therefore, in order to more effectively prevent the spread and development of the epidemic, and for the personal safety of ourselves and others, it is necessary to conduct nucleic acid testing on people on a large scale, and to use pharyngeal swabs to sample people's pharyngeal cells for nucleic acid testing.

[0004] In the prior art, when people undergo nucleic acid testing, staff are required to be present to record the user's information, provide the user with a nucleotide test kit, and perform pharyngeal cell sampling on the user. However, users who undergo nucleic acid testing sampling are largely suspected of being infected. In this way, cross-contact between users is inevitable during the testing process, which increases the probability of the tested user being infected with the virus, posing a major safety hazard. In addition, the efficiency of the entire nucleic acid testing sampling process is low and the cost is high, making it difficult to meet the high-frequency rapid nucleic acid testing sampling needs of a large group of users and individual special workers. Summary of the invention

[0005] The problem solved by the present invention is how to overcome the risk of cross-contact between staff and users, and between users due to large-scale nucleic acid testing, and avoid the situation where the collection status of throat swabs collected by users at home by themselves does not meet the requirements.

[0006] In order to solve the above problems, the present invention provides a detection method for collecting pharyngeal swabs with cotton swabs, comprising the steps of:

[0007] S1: placing a collection device on the side of the user to be collected, with the collection range of the collection device facing the side of the oral cavity of the user to be collected and the pharyngeal swab collection cotton swab, to obtain image information of the oral cavity of the user to be collected and the pharyngeal swab collection cotton swab;

[0008] S2: Start monitoring the sampling actions of the user being collected through the camera of the collection device;

[0009] S3: The sampling action includes: the user holding the pharyngeal swab and inserting the swab head of the pharyngeal swab into the oral cavity. During this process, the swab head of the pharyngeal swab is subjected to force and moves to cover the indicated area of ​​the pharyngeal swab;

[0010] S4: Identify the sampling characteristics of the user being collected based on the image information, where the sampling characteristics include the position of the current indication area and the movement state of the pharyngeal swab collection cotton swab, compare the position of the current indication area with the set depth indication area, and remind the user of the current sampling state through voice;

[0011] S5: Determine the sampling action of the user being sampled, determine whether the throat swab collection cotton swab is in a moving collection state and start timing. After the timing ends, remind the user being sampled to stop the sampling action to complete the collection.

[0012] In the above method, the collection device is stably placed on the side of the user being collected, with the camera range facing the side of the mouth of the person being collected; the camera of the collection device starts to monitor the sampling action; the user being collected holds the cotton swab in his hand and inserts the cotton swab head into the throat swab collection site in the mouth for friction collection. The monitoring function automatically identifies the head features of the sampled person based on the image, determines the depth of the sampling site, and compares it with the depth indicator color block. When the depth meets the depth requirements, a voice reminder is given that the depth is appropriate; the monitoring function automatically identifies the obstruction of the indicated area based on the image, determines the sampling intensity, and when the sampling intensity meets the requirements, a voice reminder is given that the intensity is appropriate. This method is combined with the throat swab nucleic acid collection device to reduce the difficulty of throat swab collection; realizes the collection of throat swabs at home, saves collection time, and reduces the risk of infection; avoids the clustered spread of the epidemic caused by centralized collection during general screening, reduces the input of medical staff during general screening, and speeds up general screening.

[0013] Furthermore, the process of acquiring image information includes:

[0014] S11: The acquisition device takes samples and photographs within the acquisition range at intervals to obtain photographic images;

[0015] S12: Use face recognition technology to determine whether a user appears in the image; and determine whether an indication area for a pharyngeal swab collection cotton swab appears in the recognized image. If so, obtain a sampling image of the user; if not, voice remind the user to perform the sampling operation.

[0016] Furthermore, the image information includes: an image corresponding to the indicated area of ​​the oral cavity of the collected user and the pharyngeal swab collection cotton swab and multiple position images of the pharyngeal swab collection cotton swab in a moving state.

[0017] Furthermore, the step S4 comprises:

[0018] S41: judging the depth of the sampling site and the current position of the indicated area of ​​the pharyngeal swab collection cotton swab according to the image corresponding to the oral cavity of the user being sampled and the indicated area of ​​the pharyngeal swab collection cotton swab;

[0019] S42: When the set depth is met, a voice prompt is given to the user to remind that the sampling depth has been met; whether the set depth is met is determined based on the indicated area of ​​the throat swab collection cotton swab that is blocked in the image;

[0020] S43: When the set depth is not met, a voice prompt is given to the user to readjust the sampling depth.

[0021] Furthermore, the step S5 comprises:

[0022] S51: judging whether the throat swab collection cotton swab operated by the collected user is in a moving collection state according to a plurality of position images of the throat swab collection cotton swab in a moving state.
