Disposable sterile sampling swab

Abstract

The invention belongs to the field of medical consumptive materials, and relates to a medical care inspection sampling apparatus, in particular to a disposable sterile sampling swab. The disposable sterile sampling swab consists of a fixing cap, a detachable sampling swab a, a detachable sampling swab b, a C-shaped clip and a sleeve pipe, wherein the head of the detachable sampling swab a and thehead of the detachable sampling swab b are integrally fixed through the C-shaped clip; and the fixing cap is fixedly connected with the handle parts of the detachable sampling swab a and the detachable sampling swab b which are combined, and is placed in the sleeve pipe. Through the using of the disposable sterile sampling swab disclosed by the invention, the disposable sterile sampling swab is simple in structure, convenient to use, and high in practicality; the sampling frequency can be reduced by 50%; the microorganism loading capacity of collected samples is increased, false negative of atesting result is effectively reduced, and valuable laboratory evidence is provided for correct and in-time diagnosis and treatment of clinical infectious diseases; and besides, the discomfortablenessof a patient caused by sampling is alleviated, so that the imparity degree of the patient caused by sampling is reduced.

Description

technical field [0001] The invention belongs to the field of medical consumables, and relates to a medical inspection sampling device, in particular to a disposable sterile sampling swab, which is suitable for collecting samples from infected parts such as oral cavity, nasopharynx, wound, urogenital tract, etc. Operations such as cultivation, pathogen antigen and nucleic acid detection. Background technique [0002] In the practice of clinical testing, it is often necessary to use sterile sampling swabs to collect samples from infected parts such as the oral cavity, wounds, and genitourinary tract for pathogen culture, pathogen antigen or nucleic acid detection, etc., so as to provide laboratory evidence for clinical disease diagnosis . [0003] Usually, specimen collection is one of the important links in the quality assurance of clinical examination. Specimen collection is directly related to the correctness of the test results. Introduced errors and errors. At present,...

Problems solved by technology

[0004] The survey shows that most of the disposable swabs currently on the market are single-headed swabs, which can collect one clinical specimen at a time. When clinical practice requires the detection of unknown pathogens, several throat swabs are often collected at the same time according to the patient's symptoms. Or collect several swabs from the same infection site for different types of testing. Repeated sampling with the increase in the number of samples often leads to a sharp decline in the microbial load collected from the swabs. At the same time, especially for the nasopharynx Multiple sampling often causes patients a strong sense of discomfort, leading to low patient cooperation and lower sampling quality, thereby reducing the detection rate of positive samples, etc.; children's respiratory infectious diseases will break out with seasonal changes, but children's patients Due to the low immunity, the clinical symptoms are not typical, and the children cannot report their illnesses. In order to make an accurate diagnosis and differential diagnosis, in clinical practice, 2-5 throat swabs need to be collected at the same time for inspection. In actual sampling, children often have fear. , The degree of cooperation is low, resulting in repeated sampling of the same part being unqualified, and the detection rate of positive samples is low

Relevant statistics show that among multiple swabs collected successively from the same sampling site, the effective sample volume collected by the first swab is several times that of the subsequent swabs, and children cannot even complete the collection of subsequent samples.

In clinical practice, multiple pharyngeal swabs are randomly sent for inspection, and it is impossible to guarantee that swabs with high microbial loads will be used for key screening items, resulting in false negative test results, which in turn leads to inability to confirm the clinical diagnosis of the disease and delays Treatment; Among them, in the collection of wound and genitourinary tract samples, due to the low microbial load of swabs after repeated sampling, false negative test items are also common, and the errors and errors introduced by sample collection seriously hinder clinical work
