Automatic throat swab sampling device

Abstract

The invention provides an automatic throat swab sampling device which comprises a head positioning unit of a person to be detected, a navigation positioning unit and a sample collection execution unit, the to-be-tested person head positioning unit is used for realizing head positioning, opening the oral cavity of the to-be-tested person and flattening the tongue of the to-be-tested person, and providing an unobstructed space leading to the pharynx for the tail ends of the navigation positioning unit and the sample collection execution unit; the navigation positioning unit enters the oral cavity of the to-be-detected person along with the tail end of the sample collection execution unit and is used for collecting throat images and determining depth information between the depth sensor and the throat of the to-be-detected person; the sample collection execution unit comprises a three-degree-of-freedom guide rail type device and a one-degree-of-freedom tail end execution mechanism; the guide rail type device can achieve pharyngeal wiping action of a person to be tested and control over deep feeding movement and wiping action force control parts in the oral cavity of the person to be tested, and all the units are controlled by a control end in real time. The device provides a basis for full automation of the throat swab collection process.

Description

Technical field [0001] The invention belongs to the field of medical robots, and specifically relates to an automatic throat swab sampling device. Background technique [0002] Virus infection detection methods mainly use samples collected from throat swabs for nucleic acid tests. However, throat swab sample collection is a process with a very high risk of infection and requires certain operating skills. During sampling, the patient needs to open his mouth to expose the throat. The sampling throat area is the area where the virus is relatively concentrated, and the patient can produce a large amount of droplets or aerosols when breathing hard and coughing. At present, most sampling rooms are enclosed areas of about 10 square meters, and the aerosol concentration in the sampling rooms is relatively high. Sampling medical staff to collect throat swabs at close range, even with three levels of protection (wear protective clothing, goggles, and gloves), there is a higher risk of cr...

Problems solved by technology

Sampling Medical staff collect throat swabs at close range. Even with three-level protection (wearing protective clothing, goggles, and gloves), there is a high risk of cross-infection

At the same time, during the outbreak of new coronary pneumonia, the number of infected people is large, and medical staff need to wear comprehensive protective equipment for a long time, resulting in excessive work intensity and long working hours

Moreover, due to various factors such as differences in the level of medical staff at different levels, psychological fear, and fatigue of medical staff during the collection of throat swabs, the operation of throat swab collection can easily lead to differences in swab quality and false negatives, which affect the diagnosis of the disease. judgment
