Detailed implementation manners

[0022] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0023] According to an embodiment of the present invention, there is provided a sample fixing device capable of preventing aerosol from escaping. Please refer to Figures 1 to 3, including: a cap-pulling platform 1; a fixing component 2 which is arranged on the cap-pulling platform 1 and includes two clamping fingers 21 that can move relative to each other, and the two clamping fingers 21 are moved to clamp or loosen the test tube 3 with a cap to be pulled; an adsorption component 4 which is arranged on the cap-pulling platform 1 and includes a cover body 41 and a negative-pressure adsorption member 42. The cover body 41 is covered on the test tube 3 with a cap to be pulled, an operation hole 411 is arranged on the cover body 41 and is correspondingly arranged with the tube cap of the test tube 3 with a cap to be pulled, the two clamping fingers 21 pass through the cover body 41 and enter the cover body 41, and the negative-pressure adsorption member 42 is connected to the cover body 41, and the negative-pressure adsorption member 42 sucks the gas in the cover body 41 to make the air pressure in the cover body 41 in a negative-pressure state. Before the test tube containing the sample enters the detection device, the test tube 3 with a cap to be pulled is fixed between the two clamping fingers 21 of the fixing component 2, and the tube cap is removed manually or by a mechanical gripper. During the process of opening the tube cap, the sample to be detected in the tube will volatilize to form aerosol. This is mainly because the action of pulling the cap is similar to "popping" open a champagne bottle. When the test tube in a vacuum state is opened instantaneously, the external air quickly interacts with it, producing an effect similar to sneezing, thus forming aerosol. Aerosol is composed of solid or liquid particles. The particles in the aerosol are relatively small and generally cannot be distinguished by the naked eye. Among them, microbial aerosol can spread diseases. Therefore, in order to prevent the further spread of aerosol, in this embodiment, a cover body 41 is covered on the test tube 3 with a cap to be pulled, and an operation hole 411 is reserved on the cover body 41 for the cap-pulling operation. Before pulling out the tube cap after fixing the test tube, the negative-pressure adsorption member 42 starts to work. At the moment of pulling out the tube cap, the aerosol fills the cover body 41. The negative-pressure adsorption member 42 sucks the gas from the cover body 41, making a negative pressure in the cover body 41 and sucking away the aerosol filling the cover body 41 to prevent the aerosol from spreading to the laboratory and causing harm to the staff and the laboratory. The sample fixing device capable of preventing aerosol from escaping in this embodiment solves the technical problem that the aerosol generated when pulling the cap of the test tube in the related technology may cause harm to the environment and the staff.

[0024] For the sample fixing device capable of preventing aerosol from escaping in this embodiment, the cover body 41 is made of a transparent material. Preferably, the cover body 41 is made of glass to facilitate observing the situation of the test tube 3 with a cap to be pulled in the cover body 41 in real time.

[0025] Refer to Figure 1 and Figure 3 , for the sample fixing device capable of preventing aerosol from escaping in this embodiment, the negative-pressure adsorption member 42 is a fan 421. The fan 421 is fixed below the cap-pulling platform 1. A perforation is arranged on the cap-pulling platform 1, and the fan 421 sucks the gas from the cover body 41 located above the cap-pulling platform 1 through the perforation. There is a perforation on the cap-pulling platform 1, the cover body 41 is fixed above the cap-pulling platform 1, and the fan 421 is fixed below it. The fan 421 sucks the air from the cover body 41 above through the perforation.

[0026] Refer to Figure 3 , for the sample fixing device capable of preventing aerosol escape in this embodiment, the adsorption assembly 4 further includes a filter 43. The filter 43 is arranged below the cap-pulling table 1, and the filter 43 is located between the cap-pulling table 1 and the fan 421. The filter 43 is used to filter and purify the aerosol from the inside of the cover 41. The harmful microbial aerosol inside the cover 41 is sucked into the filter 43 by the fan 421. The filter 43 includes a primary filter and a high-efficiency filter. The inhaled air first passes through the primary filter to remove larger particles, and then passes through the high-efficiency filter to purify the harmful aerosol. The double-layer filter not only ensures the use efficiency, but also ensures the filtering effect and the service life of the filter. The inside of the adsorption assembly 4 is filled with a sealing material to ensure the airtightness from the perforation to the fan 421.

The tube cap transmission assembly 5 includes a pipeline channel 51 and a medical waste bin 52. The pipeline channel 51 passes through the cap-pulling table 1. The inlet 511 of the pipeline channel 51 is arranged at an interval from the operation hole 411. The medical waste bin 52 is located below the cap-pulling table 1. The pipeline channel 51 is connected to the medical waste bin 52. The removed test tube cap is taken out from the operation hole 411, thrown into the inlet 511, and slides down along the pipeline channel 51 into the medical waste bin 52 for centralized collection of test tube caps.

[0028] Refer to Figure 2 and Figure 3 , for the sample fixing device capable of preventing aerosol escape in this embodiment, the sample fixing device capable of preventing aerosol escape further includes an ultraviolet lamp 6. The ultraviolet lamp 6 is fixed below the cap-pulling table 1 and above the medical waste bin 52. The ultraviolet lamp 6 is used to sterilize the tube caps in the medical waste bin 52. The ultraviolet lamp 6 irradiates the medical waste bin 52 to sterilize the test tube caps centrally collected in the medical waste bin 52.

[0029] Refer to Figure 2 , for the sample fixing device capable of preventing aerosol escape in this embodiment, the sample fixing device capable of preventing aerosol escape further includes a proximity switch sensor 7. The proximity switch sensor 7 is fixed above the cap-pulling table 1 and is arranged at an interval from the inlet 511. The proximity switch sensor 7 is used to sense the tube caps entering the inlet 511. The pipeline channel 51 is fixed to the cap-pulling table 1 by a locking clip. The locking clip is sleeved on the pipeline channel 51. The locking clip is detachable relative to the cap-pulling table 1 for easy loading, unloading and replacement. The proximity switch sensor 7 is installed on the locking clip. The proximity switch sensor 7 can sense the entry of the pipeline channel 51 into the test tube cap. After giving a prompt, the ultraviolet lamp 6 is synchronously turned on.

[0030] Refer to Figure 2 and Figure 3 For the sample fixing device capable of preventing aerosol from escaping in this embodiment, the sample fixing device capable of preventing aerosol from escaping further includes a controller, and the controller is respectively signal-connected to the ultraviolet lamp 6 and the proximity switch sensor 7. When the proximity switch sensor 7 senses that the pipeline channel 51 enters the test tube cap, the controller transmits a signal to the ultraviolet lamp 6 to turn on the ultraviolet lamp 6, disinfect and sterilize the waste cap that has fallen into the medical waste bin 52, so as to eliminate the possible safety and health hazards in the discarded test tube cap.

[0031] Refer to Figure 1 For the sample fixing device capable of preventing aerosol from escaping in this embodiment, the fixing assembly 2 further includes a driving motor 22. The driving motor 22 is connected to the two clamping fingers 21. The driving motor 22 and the cover body 41 are arranged at intervals on the cap-pulling table 1. The driving motor 22 is used to drive the two clamping fingers 21 to move. The driving motor 22 drives the two clamping fingers 21 to move relatively, so as to clamp or release the test tube 3 to be uncapped.

[0032] Refer to Figure 3 For the sample fixing device capable of preventing aerosol from escaping in this embodiment, a protective component is arranged on one side of each of the two clamping fingers 21 close to the test tube 3 to be uncapped, and the protective component is made of rubber material. Rubber pads are attached to the inner sides of the two clamping fingers 21, which can not only play an anti-slip role, but also prevent the test tube from being damaged due to excessive clamping force.

[0033] For the sample fixing device capable of preventing aerosol from escaping in this embodiment, after the two clamping fingers 21 clamp the test tube, the negative pressure suction component 42 starts to work, sucks air into the cover body 41, so that the inside of the cover body 41 is in a negative pressure state. The aerosol generated in the test tube instantly during the process of manually or mechanically removing the cap is sucked away by the negative pressure suction component 42 for the first time, so that the aerosol cannot remain inside the cover body 41, avoiding the situation that a small amount of aerosol is mixed in the subsequent test tubes, and ensuring the accuracy of the subsequent test tube inspection operation results. The removed test tube cap is discarded, enters the pipeline channel 51 from the inlet 511, and the discarded test tube cap falls into the medical waste bin 52 below through the pipeline channel 51, and is also disinfected and sterilized by the ultraviolet lamp 6 above it.
