Robot for collecting pharyngeal flora

Abstract

The invention relates to a robot for collecting pharyngeal flor, the robot comprises a head fixing and positioning mechanism, a variable stiffness mechanism, a mechanical arm and a sampling table. When pharyngeal flora is collected, a lead screw mechanism in a head fixing and positioning mechanism in the robot can be adjusted according to the size of the head of a to-be-detected person, the effect of fixing the head of the to-be-detected person is achieved, after head positioning is completed, a detector follows a designed technical route, through control by a controller, the tail end of the pharyngeal flora collection robot can realize a motion path similar to that of manual collection to complete collection of pharyngeal flora; a variable stiffness mechanism is adopted, hard contact between the tail end of the pharyngeal flora collection robot and the pharynx of a to-be-detected person is avoided, meanwhile, a head fixing and positioning mechanism is composed of a parallel mechanism and a lead screw, good supporting performance and adaptability are provided, and the robot is suitable for wide crowds; when the tester operates the robot, the designed technical route is followed, the accuracy of collected samples is high through accurate control, and an accurate result can be obtained through detection.

Description

technical field [0001] The invention relates to the field of medical devices, and is a robot for collecting pharyngeal flora, specifically, a robot capable of collecting pharyngeal flora. Medical personnel can make the robot automatically complete the collection of pharyngeal flora samples by operating the control interface , the robot can play an effective isolation role and improve the safety of medical staff. At the same time, the robot has high accuracy and reliability, and the sample collection efficiency is high. Background technique [0002] Since the outbreak of the new crown epidemic, it has shown a very strong contagiousness. In order to effectively cut off the spread of the virus and detect virus carriers in the crowd in a timely manner, nucleic acid testing has gradually become normalized. Therefore, more and more experts and scholars have begun to develop automatic Device for collecting samples of pharyngeal flora. [0003] For the design of the existing pharyn...

Problems solved by technology

[0003] Regarding the design of the existing pharyngeal flora collection device, the invention patent of publication number CN111643123A "An Automatic Sampling Device for Throat Swab" adopts a gantry-type three-axis The mechanism realizes mechanical movement. When the device collects samples, the end of the device only realizes movement in one direction, which is quite different from manual collection.

In addition, in the invention patent "Robot System for Pharyngeal Swab Collection" with publication number CN111673757A, the pharyngeal flora clamping device does not use a flexible mechanism, which will irritate the throat tissue of the subject during collection.
