Pharyngeal swab collecting mechanical arm

Abstract

The invention relates to the technical field of medical automation equipment, in particular to a throat swab collecting mechanical arm which comprises a swinging system, a driving motor system, a driving line system and a rotating system. The swinging system comprises a lower mounting base (4), an arc-shaped connecting rod (11), an upper connecting piece (111), a lower connecting piece (112) and an upper swinging base (7); the driving motor system comprises a front-back swinging motor (2), a stepping motor speed reducer (21), a left-right swinging motor (12), a gear (14), a telescopic stepping motor (15) and a rotary stepping motor (16); the driving line system comprises a winding grooved wheel (3), a front-back swinging driving line (5), a front-back swinging elastic line (51), a left-right swinging elastic line (6), a left-right swinging driving line (61), a grooved wheel bearing (9), a shaft sleeve (91) and a fixed shaft (92); the rotating system comprises a rotating bearing (8) and a UPU connecting structure (10); the mechanical arm is high in stability, high in precision and more suitable for human oral cavity collection.

Description

technical field [0001] The invention relates to the technical field of medical automation equipment, in particular to a throat swab collection mechanical arm. Background technique [0002] The new coronavirus is sweeping the world. One of the most effective ways to detect the new coronavirus is the throat swab nucleic acid test. Pharyngeal swab nucleic acid detection can quickly and accurately identify the new coronavirus. However, at present, hospitals still use manual collection, and the design and development of automatic collection equipment is not yet mature. During manual collection, the collected person needs to take off the mask and open his mouth to face the medical staff, which poses a great threat to the safety of the medical staff, and also poses a challenge to the physical strength of the medical staff during mass collection. [0003] At present, scholars from various countries have begun to design and research automated throat swab collection equipment. In t...

Problems solved by technology

However, the six-axis robotic arm has the characteristics of large size, complicated control, and high requirements for operators, so it is not suitable for all hospitals and medical staff.

In addition, the cost of the six-axis robotic arm is too high, and there is great resistance in the process of popularizing automated throat swab collection equipment on a large scale
