Description
Technical Field
The invention belongs to the field of medical consumables, and relates to a medical examination sampling device, in particular to a disposable sterile sampling swab which is suitable for collecting samples of infected parts such as oral cavities, nasopharynx, wound surfaces, genitourinary tracts and the like for operations such as pathogen culture, pathogen antigen and nucleic acid detection and the like.
background
in clinical examination practice, a sterile sampling swab is often used for collecting samples of infected parts such as oral cavity, wound surface, genitourinary tract and the like so as to perform operations such as pathogen culture, pathogen antigen or nucleic acid detection and the like, thereby providing laboratory evidence for clinical disease diagnosis.
generally, specimen collection is one of important links for quality assurance of clinical examination, and specimen collection is directly related to whether a test result is correct or not, and if the specimen is improperly collected, even the best instrument and equipment and the strictest experimental operation are difficult to make up for errors and mistakes introduced during specimen collection. At present, a disposable sterile sampling swab is often used for sampling an infected part in clinical examination work, the disposable sterile sampling swab is mostly connected with a sampling head through a handheld plastic handle, and the disposable sampling swab can only collect a sample for one examination item; however, when detecting unknown pathogens clinically, it is often necessary to collect a plurality of samples at the same time to perform different test items respectively in order to screen pathogenic microorganisms.
Investigation shows that most of disposable sampling swabs on the market at present are single-head swabs, and can collect one clinical specimen at one time, when the clinical practice needs to detect unknown pathogens, a plurality of pharyngeal swabs are collected at the same time or a plurality of swabs are collected at the same infected part according to the symptom of a patient for different types of detection, and repeated sampling along with the increase of the sampling times is carried out, so that the condition that the microbial load collected by the existing sampling swabs is sharply reduced is often caused, and meanwhile, the repeated sampling of nasopharyngeal parts causes strong discomfort of the patient, so that the patient has low degree of matching and the sampling quality is reduced, and the detection rate of positive specimens is reduced, and the like; infectious diseases of the respiratory system of children can outbreak and become epidemic along with seasonal changes, but the children patients have atypical clinical symptoms due to low immunity, and the sick children cannot self-describe the illness state, in order to accurately diagnose and identify and diagnose, 2-5 pharyngeal swabs need to be collected simultaneously in clinical practice for inspection, the fear and the low degree of matching of the sick children often appear in actual sampling, the defects of unqualified repeated sampling of the same part and low detection rate of positive specimens are caused. Statistics shows that in a plurality of swabs collected successively at the same sampling part, the effective sample amount collected by the first swab is multiple times of that collected by the later swabs, and children even cannot finish the collection of subsequent samples. In clinical practice, the submission of a plurality of pharyngeal swabs after sampling is random, so that the swabs with high microbial load cannot be guaranteed to be used for key screening project inspection, the detection result is false negative, further, the disease diagnosis cannot be clearly determined in clinic, and the treatment is delayed; in the collection of samples of wound surfaces and genitourinary tracts, false negative conditions of detection items are also common due to low microbial load of sampling swabs after repeated sampling for many times, and errors caused by sample collection seriously hinder clinical diagnosis and treatment work.
