Referring to fig. 1 to 3, a swab scraping test tool according to an embodiment of the present application will now be described. The swab scraping test fixture is used for detecting the scraping force of the swab 2000, and particularly is used for detecting the scraping force of the swab 2000 of the automatic throat swab sampling machine on the throat. It will be appreciated that in other cases, the swab scraping test tool may be used to detect the scraping force of the swab 2000 during manual detection, which is not limited only.

The swab scraping test tool comprises a scraping member 100 and a pressure sensor 200; a piece of flexible material of the scraper 100, the scraper 100 having a scraper surface 110 for scraping by the swab 2000 and a connecting surface 120 arranged opposite to the scraper surface 110; the pressure sensor 200 is connected to the connection surface 120 of the scraper 100 and is used for detecting the stress magnitude of the scraper 100, and the pressure sensor 200 is arranged to be in communication connection with an upper computer.

It should be noted that, the throat of the human body is softer, that is, the swab scrapes on the soft object during sampling, so in the embodiment of the application, the scraper 100 is made of a soft material, so that the scraper 100 is more close to the touch of the throat, and the pressure detection of the swab is more lifelike and has higher precision.

Next, the swab 2000 scrapes on the scraping surface 110 of the scraper 100, and the pressure sensor 200 is connected to the connecting surface 120 of the scraper 100, the scraping surface 110 is opposite to the connecting surface 120, and the force acting on the scraping surface 110 by the swab 2000 is the same as the force acting on the pressure sensor 200 by the connecting surface 120, so that the scraping force of the swab 2000 can be detected by detecting the acting force on the connecting surface 120 by the pressure sensor 200.

In addition, the pressure sensor 200 is connected with the upper computer in a communication manner, so that the pressure sensor 200 can feed back the pressure value detected each time to the upper computer. The upper computer can directly feed back the pressure value to the automatic throat swab sampling machine, so that the automatic throat swab sampling machine can judge whether the scraping force of the automatic throat swab sampling machine on the throat part is proper or not, and meanwhile, the scraping force can be adjusted according to the pressure. Or the upper computer analyzes and evaluates the multiple groups of pressure values and controls and adjusts the scraping force of the automatic throat swab sampling machine. Or, the staff can directly adjust the scraping force of the automatic throat swab sampling machine according to the pressure value.

In one embodiment, the scraper members 100 are made of a flexible plastic material that is resilient, deforms when subjected to a force, and returns to its original state when not subjected to a force. In addition, the soft gum is soft to the touch of the skin, so that the scraping force measurement accuracy is higher.

It should be noted that, the peripheral edge of the scraping element 100 refers to a peripheral sidewall of the scraping element 100 between the scraping surface 110 and the connecting surface 120; a peripheral sidewall of the base 300 refers to a peripheral sidewall of the base 300 between the wiper 100 and the pressure sensor 200. A peripheral sidewall of the substrate 300 protruding beyond a peripheral sidewall of the scraper 100 means that the projected contour of the scraper 100 is surrounded by a peripheral edge of the substrate 300 when the scraper 100 is projected onto the substrate 300. It may be possible to allow the substrate 300 to still fully support the scraper 100 when the scraper 100 is deformed under force, while reducing the likelihood that the scraper 100 will fail to recover after deformation due to deformation beyond the substrate 300, thereby failing to detect multiple times.

Alternatively, the scraping member 100 may be mounted to the substrate 300 by means of adhesion, or the scraping member 100 may be coupled to the substrate 300 by means of two-shot molding.
