Description

Technical Field

[0002] A virus is a non-cellular life form. It consists of a long nucleic acid chain and a protein coat. Viruses do not have their own metabolic mechanisms or enzyme systems. Therefore, outside the host cell, a virus becomes a chemical substance without any life activities and cannot reproduce independently. Its abilities of replication, transcription, and translation are all carried out in the host cell. When it enters the host cell, it can utilize the substances and energy in the cell to complete life activities and produce a new generation of viruses identical to it according to the genetic information contained in its own nucleic acid.

[0003] Currently, when detecting viruses, immunolabeling techniques are usually adopted, that is, antibodies are labeled with fluorescein, radionuclides, peroxidase, etc., and observed through a microscope to detect antigens in the test specimen, so as to conduct early diagnosis of virus infection. However, due to the insufficient sealing of existing virus detection equipment and the fact that viruses usually have strong fluidity and adhesiveness, when detecting viruses, some viruses are likely to enter the human body with the air, posing a relatively large potential safety hazard.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1-9 shown, a virus detection device for improving detection safety includes a box body 1 provided with a detection chamber 7. A disinfection assembly for disinfecting viruses is provided in the box body 1. The box body 1 is fixed on a bottom plate 6. An inlet 15 communicating with the detection chamber 7 is provided on the side of the box body 1. Two groups of sealing doors 5 are provided at the inlet 15 in a sealed sliding manner. Each group of sealing doors 5 has two and they are mutually attached and sealed. Each of the two sealing doors 5 in the same group is provided with a convex plate 50. One side of the convex plate 50 is provided with a sealing groove 502 opened on the sealing door 5. A sealing airbag 501 that can be inserted into the sealing groove 502 and is in contact with and sealed to the sealing groove 502 is provided on the convex plate 50. The sealing airbag 501 gradually expands and contracts as the sealing door 5 is opened and closed;

[0041] A negative pressure assembly for controlling the pressure in the detection chamber 7 is provided in the box body 1. A detection assembly 16 for detecting viruses is provided on the box body 1;

[0042] The disinfection component includes a spray head or a misting head, a pressurizing water pump, and a liquid storage tank, which are used to spray disinfected water into the detection chamber 7 and the inlet 15. Some existing publicly available disinfection equipment can also be used to achieve the disinfection effect.

[0043] During use, the user places the reagent tube 14 on the detection component 16. At this time, the adjacent first group of sealing doors 5 opens. During the opening process, the corresponding airbag gradually contracts to reduce wear. After the sealing door 5 is opened, the detection component 16 moves the reagent tube 14 between the two sealing doors 5. After the first group of sealing doors 5 closes and the convex plate 50 is inserted into the sealing groove 502, the airbag is inflated to ensure the sealing effect. Then the second group of sealing doors 5 opens, and the detection component 16 transfers the reagent tube 14 into the detection chamber 7. The user can check the virus situation through the detection component 16.

[0044] During the use process, the negative pressure component works to keep the detection chamber 7 under negative pressure all the time.

[0045] Preferably, a pressure device for detecting pressure is arranged in the detection chamber 7, and the pressure device is connected to a control circuit board or a control device such as a PLC that can control the negative pressure component and the negative pressure electric control ball valve 19 according to the situation, so as to control the operation of the negative pressure component according to the pressure change in the detection chamber 7.

[0046] In this embodiment, two drive chambers are provided on both sides of the inlet 15 in the box body 1. The drive chambers are connected to the negative pressure component, and the drive chambers are connected to the detection chamber 7 through the negative pressure electric control ball valve 19. A drive component is arranged in each drive chamber. The same drive component drives two groups of sealing doors 5 on the same side of the inlet 15 respectively, and only one sealing door 5 opens or closes when the drive component rotates in one direction. The two drive components are both connected to the same door opening motor 20.

[0047] An air extraction and exhaust component is also arranged in the drive chamber. The air extraction and exhaust component is connected to the sealing airbag 501, and gradually fills the sealing airbag 501 with air or discharges the gas in the sealing airbag 501 when the two sealing doors 5 in the same group approach or move closer to each other.

[0048] When it is necessary to open the sealing door 5, the door opening motor 20 is controlled to rotate forward or backward according to the sealing door 5 to be opened, so that the corresponding sealing door 5 opens. During the opening process of the sealing door 5, the air extraction and exhaust component first connects to the drive chamber, so that the negative pressure in the drive chamber quickly extracts the gas in the sealing airbag 501 to reduce wear.

[0049] When it is necessary to close, the corresponding sealing door 5 can be driven to close through the drive component.

[0050] During the use process, a corresponding pressure detection device can also be arranged in the driving cavity, and the vacuum pump 18 can be controlled to extract air through the control devices such as the control circuit board or PLC pointed out above to ensure the normal operation of the driving component.

[0051] In this embodiment, the driving component includes two sets of threaded telescopic rods 503, two worm and gear assemblies 52 independently driving the threaded telescopic rods 503, two ratchet and pawl mechanisms 53 driving the worm and gear assemblies 52, and two pneumatic motors 59 connected to the worm and gear assemblies 52. The ratchet and pawl mechanisms 53 are driven by the opening motor 20 through the bevel gear 171 and the transmission rod, and the driving directions of the two ratchet and pawl mechanisms 53 are opposite;

[0052] Each set of threaded telescopic rods 503 has two and is arranged vertically. One end of the threaded telescopic rod 503 is rotatably connected in the driving cavity, and the other end of the threaded telescopic rod 503 is fixed on the sealing door 5;

[0053] The pneumatic motor 59 is connected to the outside of the box body 1 through the driving electric ball valve 51;

[0054] When the sealing door 5 needs to be opened, the opening motor 20 works. Under the action of the ratchet and pawl mechanism 53, the opening motor 20 is driven by the corresponding worm and gear assembly 52 and drives the threaded telescopic rod 503 to extend. When it needs to be closed, the driving electric ball valve 51 is controlled. In the negative pressure environment of the driving cavity, air enters the pneumatic motor 59 through the driving electric ball valve 51. The pneumatic motor 59 rotates and drives the worm and gear assembly 52 to rotate, and then the threaded telescopic rod 503 contracts;

[0055] Among them, the driving electric ball valve 51 can also be replaced by a three-position four-way valve or a valve capable of controlling the on-off of two pipelines. Each pipeline is connected to the two pneumatic motors 59 of a group of sealing doors 5 so that only a group of sealing doors 5 can be controlled each time.

[0056] In this embodiment, the air extraction and exhaust component includes a pressurization channel 58 opened in the sealing door 5, a sealing piston 57 hermetically inserted in the pressurization channel 58, a communication barrel 56 hermetically inserted in the pressurization channel 58, and a rotating rod 54 hermetically and rotatably connected in the communication barrel 56. The pressurization channel 58 is provided with an opening communicating with the sealing airbag 501;

[0057] A circular hole connected to the connecting barrel 56 is provided at one end of the rotating rod 54 located inside the connecting barrel 56, a limiting protrusion 541 is provided on the outer circumferential side of the rotating rod 54, and the connecting barrel 56 is provided with an arc groove 561 for the limiting protrusion 541 to slide, and the connecting barrel 56 and the rotating rod 54 are both provided with a connecting hole 55, and when the limiting protrusion 541 rotates to the two ends of the arc groove 561, the two connecting holes 55 overlap or do not overlap, and the rotating rod 54 is connected to the worm gear assembly 52 for transmission, and the two threaded telescopic rods 503 on the same sealing door 5 are driven by a transmission belt and a transmission wheel, and the rotating rod 54 is provided with a transmission wheel driven by the transmission belt, wherein in order to ensure accurate transmission, corresponding teeth and tooth grooves are provided on the transmission belt and the transmission wheel, and correspondingly, the transmission belt can also be replaced by other transmission methods;

[0058] When the sealing door 5 is opened, the rotating rod 54 rotates according to the rotation direction of the threaded telescopic rod 503. When the limiting protrusion 541 abuts against one end of the arc groove 561, the two connecting holes 55 overlap to discharge the gas in the airbag. When the sealing door 5 is closed, the limiting protrusion 541 rotates to the other end of the arc groove 561. At this time, the two connecting holes 55 no longer overlap, and as the sealing piston 57 moves, the gas in the pressurized channel 58 gradually enters the airbag to make the airbag expand.

[0059] Since the driving chamber is in a negative pressure environment, the air pressure generated by the displacement of the sealing plug of the pressurized channel 58 is relatively small, so that after the sealing plug moves to the sealing groove 502, the airbag gradually expands. In order to ensure the sealing effect of the sealed airbag 501, the cross-sectional area of ​​the pressurized channel 58 can be adjusted according to the gas required for the expansion of the airbag, the driving chamber pressure, and the length of the pressurized channel 58 to ensure the smooth expansion of the airbag.

[0064] The filling needle 35 can be rotated above the reagent tube 14, and the filling needle 35 is connected through a pipeline to a peristaltic pump 12 located in the box body 1. The peristaltic pump 12 is connected to a liquid storage cavity 13 opened on the box body 1. The liquid storage cavity 13 can be set to multiple, and the peristaltic pump 12 and the multiple liquid storage cavities 13 are switched on and off through pipelines and electric control valves, so that different liquids can be dropped into the reagent tube 14;

[0065] During use, the rodless cylinder 32 drives the displacement plate 37 to move above the transfer assembly, and then the rotation motor 31 drives the displacement plate 37 to rotate, so that the clamping member 33 moves above the reagent tube 14 and removes the test tube stopper. Then the displacement plate 37 drives the filling needle 35 to move above the reagent tube 14 and drop the liquid medicine. After the dropping is completed, the rodless cylinder 32 drives the moving plate 36 to reset, and the personnel observes the virus in the reagent tube 14. Finally, after the observation of the reagent tube 14 is completed, the clamping member 33 installs the test tube stopper on the reagent tube 14.

The two ends of the arc-shaped groove 561 are respectively far from the axis of the rotating plate 334 and close to the axis of the rotating plate 334. A follower fixed on the guide rod 332 is arranged in the arc-shaped groove 561, and the follower can move along the radial direction of the lifting plate 333;

[0068] A clamping motor 34 in transmission connection with the transmission ring 335 is fixed on the displacement plate 37. The transmission ring 335 can drive the transmission cylinder 336 to rotate. A convex strip is arranged on the outer circumferential side of the transmission cylinder 336 along the axial direction, and a groove inserted on the convex strip is formed on the transmission ring 335;

[0069] When it is necessary to clamp the test tube stopper, the clamping motor 34 drives the rotating plate 334 to rotate, the follower moves along the arc-shaped groove 561 and drives the guide rod 332 to gradually move towards the axis of the lifting plate 333, so that the clamping plate 331 clamps the test tube stopper. When it is necessary to loosen, the clamping motor 34 is controlled to reverse;

[0070] When it is necessary to drive the test tube stopper to separate from the reagent tube 14, the electric telescopic rod is controlled to contract. Similarly, when installing the test tube stopper, the electric telescopic rod is controlled to extend;

[0071] As an alternative solution, the clamping member 33 can be replaced with a clamping device such as a jaw cylinder.
