Embodiment 1

[0047] exist Figure 1-Figure 9 In the schematic diagram of the end operation head of the automatic sampling equipment shown, the soft end operation head 1 attracts the four sets of electromagnets 202 in the rigid base 2 to the corresponding four annular iron cores 103 embedded in the soft execution part 102. It is closely attached to the outer surface of the rigid base 2, and the connection of the four groups of air passages is realized through the compression deformation of the soft material. The rigid base 2 then passes through its upper cover 201, lower cover 207 and finally screwed into the four screws 203 in the reserved screw holes on the end surface of the UR mechanical arm 3 to realize the fixing of itself and the end surface of the UR mechanical arm 3.

[0048] The soft operation head 1 includes a throat swab 101, a soft execution part 102 and an annular iron core 103. The overall appearance of the software operating head 1 is flat cylindrical, one end is connected ...

Embodiment 2

[0056] The main difference between this embodiment and Embodiment 1 is that the iron core 103 is directly used as the alignment part, and the electromagnet 202 is used as the guide part, specifically:

[0057] The iron core 103 protrudes from the surface of the base butt joint surface. Preferably, considering the stability of the iron core 103, the iron core 103 can still be buried under the base butt joint surface, thereby forming a bulge on the base butt joint surface. , the surface of the iron core 103 is covered with a layer of flexible material, and the flexible material automatically forms a smooth guide surface with a certain taper, such as Figure 10 shown.

[0058] The electromagnet 102 is recessed into the installation surface of the operating head, and the shape of the recess matches the protruding shape of the iron core 103. Preferably, in this embodiment, the electromagnet 102 is directly made into a ring shape, and the radius of the hole in the middle is It is l...

Abstract

The invention belongs to the technical field of nucleic acid test sampling, and provides a flexible operating head, a rigid base and a facility for nucleic acid test sampling. On the basis of the principle that a cavity formed inside a flexible material can deform in the air inflation and deflation and/or pumping process, the flexible operating head with an air cavity structure is obtained and used for allowing a throat swab to be installed and controlling the throat swab to conduct sampling operation, and therefore a medical worker does not need to hold the throat swab to conduct operation byhimself in the sampling process. The flexible operating head can cooperate with the rigid base and a mechanical arm to be used, and therefore the facility which can allow the medical worker to conduct long-distance sampling operation is obtained, the medical worker is prevented from touching a patient in a short-distance mode, and the infection risk is reduced. In addition, the replacement of thedisposable flexible operating head can be automatically accomplished on the basis of the magnetic attraction connection principle, the process is safe and effective, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection and sampling, and relates to a software operating head, a rigid base and equipment for nucleic acid detection and sampling, and more specifically, to a terminal operating head for automatic sampling equipment for nucleic acid detection, especially a An operation head that can be integrated at the end of a robotic arm to realize fully automated and safe sampling, and can be used for remote operation. Background technique [0002] Nucleic acid detection is one of the important basis for the diagnosis of the new coronavirus. It is necessary for the medical staff wearing protective clothing to personally hold the throat swab to scrape the cell samples and tissue mucus from the patient's throat, and store them in the test tube culture medium for further investigation. The sent inspection draws conclusions. [0003] In the process of manual sampling, although strict protection has been d...
