Description

Biological sample collection swab Technical Field The utility model relates to the technical field of medical instruments, in particular to a biological sample collection swab. Background The biological sample collecting swab is generally operated by a doctor and used for being inserted into a patient to collect a biological sample, and is applied to respiratory tract detection, gynecological detection and the like. The collection of biological samples is critical for the diagnosis and treatment of diseases, which can provide important information about the health of the patient. However, the examination in the hospital faces the problems of long queuing, slow output and the like, and along with the wide application of the internet technology, a user can select to collect samples from the household swab and deliver the samples to the hospital or a detection center for detection by a rider, so that queuing is not needed and the output is faster. However, the existing biological sample collection swab is more in line with the use habit of doctors, and when a user uses the swab alone, the collected biological sample is invalid and even damages the body due to the incorrect use mode. It follows that existing collection swabs are not suitable for users to complete the collection of biological samples on their own. Disclosure of utility model The utility model aims to provide a biological sample collection swab suitable for self-sampling of a user. In order to achieve the above purpose, the utility model adopts the following technical scheme: a biological sample collecting swab is characterized by comprising a swab head, a connecting rod and a handheld part, The swab head is positioned at one end of the connecting rod and is used for collecting biological samples; the handheld part is positioned at the other end of the connecting rod, and the width of the handheld part is equal to or larger than that of the connecting rod, so that the handheld part is convenient to hold; The surface of the swab head is also provided with color-changeable flocking, and after a biological sample is detected, the surface of the swab head is color-changed, so that the effectiveness of sample collection can be judged conveniently. The region with the widest diameter of the swab head is provided with color-changing flocking, when a biological sample is detected, the region with the widest diameter of the swab head is subjected to color-changing reaction, and a color-changing ring is formed on the swab head, so that the effectiveness of sample collection is conveniently judged according to the color depth. The swab further comprises a baffle, one end of the baffle is a connecting rod, and the other end of the baffle is a handheld part; the width of the baffle is larger than that of the handheld part and the baffle of the connecting rod, and the baffle is the widest part of the swab and is used for limiting the depth of the swab entering the body. The baffle, the hand-held part and the connecting rod are in transition design, and particularly, the baffle is gradually widened from the connecting rod to the baffle, and the baffle is gradually narrowed to the handle. The whole water droplet shape that is of swab head, the one end that the connecting rod was kept away from to the swab head is wider than the one end that swab head and pole connect to link to each other. The connecting rod is also provided with a breaking part, the diameter of the breaking part is smaller than that of the connecting rod, the breaking part is provided with the narrowest part of the swab, or the material strength of the breaking part is lower than that of the connecting rod, and when the connecting rod is subjected to the force in a preset range, the breaking part breaks. The connecting rod, the baffle and the handheld part are made of ABS materials, and PTFE coatings are arranged on the surfaces of the connecting rod, the baffle and the handheld part and used for reducing friction resistance of in-vivo sampling. The ratio of the length of the hand-held part to the length of the swab ranges from 0.2 to 0.6. The connecting rod, the baffle and the hand-held part are integrally injection molded. The surface of the hand-held part is provided with a friction-increasing etching. According to the biological sample collection swab provided by the utility model, the color-changing flocking is arranged on the surface of the swab head, so that the effectiveness of the collected biological sample can be judged through the color change of the color of the swab head. In addition, through setting up safety shield on the sampling pole, prevent that the user from using the swab, the penetration is too dark to harm the health. The foregoing objects, features and advantages of the disclosure will be more readily apparent from the following detailed description of the preferred embodiments taken in conjunction with the accompanying drawings.
