Description

Technical Field

[0001] This invention relates to the field of in vitro testing technology, and in particular to an in vitro testing emergency sample loading and transmission device. Background Technology

[0002] In the process of sample analysis, in vitro diagnostic instruments may encounter emergency situations, requiring the instruments to have emergency sample placement and collection capabilities. Currently, most emergency mechanisms in in vitro diagnostic instruments are motor-driven structures, such as linear and rotary drives. Regardless of the drive method, they all suffer from large space requirements and high costs. Therefore, developing a low-cost and more space-efficient emergency sample collection mechanism has significant practical value.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an in vitro testing emergency sample loading and transmission device that reduces space occupation and lowers costs.

[0005] The technical solution of the present invention is as follows: An in vitro diagnostic emergency sample loading and transfer device is provided, comprising: a support frame, a support base mounted on the support frame and provided with a movable groove, a position optical coupler sensor mounted on the support frame, a sample holder disposed in the movable groove, a detection optical coupler sensor mounted in the sample holder, and an optical coupler baffle connected to the sample holder; the sample holder is provided with a sample placement slot, and the detection optical coupler sensor faces the sample placement slot; the sensing area of ​​the position optical coupler sensor overlaps with the range of motion of the optical coupler baffle. The movable groove provides an active area for the sample holder, the position optical coupler sensor determines whether the sample holder has moved to a predetermined position by detecting the optical coupler baffle, the sample placement slot is used to place the sample to be tested, and the detection optical coupler sensor is used to detect whether the sample placement slot contains the sample to be tested.

[0006] When testing emergency samples, the sample holder is first moved to one end of the moving slot, the sample to be tested is placed into the sample placement slot, and then the sample holder is pushed to the other end of the moving slot. The position optocoupler sensor detects that the sample holder has reached the predetermined position, and the detection sensor also detects the presence of the sample to be tested in the sample placement slot. The in vitro diagnostic instrument can then perform testing on the sample. Because no motor-driven mechanism is used, costs are greatly reduced, and space occupancy is also minimized, making it highly practical and convenient to use.

[0007] The moving groove is provided with a guide slide, and the sample holder is provided with a guide slider, which matches the guide slide. The guide slider and the guide slide allow the sample holder to move more stably within the moving groove.

[0008] The in vitro diagnostic emergency sample loading and transfer device further includes a handle connected to the sample holder, the handle being positioned above the support base. The handle allows for easy pushing of the sample holder.

[0009] The in vitro diagnostic emergency sample loading and transmission device further includes: an RFID reading module, a left cover plate, a right cover plate, and a test tube baffle, all mounted on the support base. The RFID reading module is used to read the current sample holder, the number of the sample to be tested within the sample holder, and other information. The left and right cover plates prevent liquid from the sample from spilling into the in vitro diagnostic instrument. The test tube baffle is used to assist the in vitro diagnostic instrument in sampling.

[0010] The RFID reading module includes: a mounting plate and a protective cover connected to the support base, an RFID card, and insulating rings at both ends that abut against the mounting plate and the RFID card, respectively; screws pass through the RFID card and the insulating rings to connect to the mounting plate, and the protective cover covers the RFID card. The insulating rings prevent the RFID card from directly contacting the mounting plate.

[0011] A first magnet is provided at one end of the movable slot, and a second magnet is provided on the side of the sample holder facing the first magnet. The first magnet and the second magnet attract each other. Alternatively, a magnet is provided at one end of the movable slot, and an iron plate is provided on the side of the sample holder facing the magnet; or an iron plate is provided at one end of the movable slot, and a magnet is provided on the side of the sample holder facing the iron plate. The mutual attraction between the first and second magnets or between the magnet and the iron plate makes the sample holder more stable, facilitating sampling by in vitro diagnostic instruments.

[0012] The position optical coupler sensor is disposed below the support base, and the optical coupler baffle is connected to the lower end of the sample holder. The support frame has a first elongated hole through which the optical coupler baffle passes. Distributing the position optical coupler sensor below the support base significantly saves space and facilitates practical applications.

[0013] The support frame is provided with a second elongated hole, and a pressure plate is connected to the bottom of the sample holder, the pressure plate being disposed within the second elongated hole. The pressure plate is used to hold down the cable connected to the detection optical coupler sensor, preventing the cable from becoming tangled and rubbing against the second elongated hole, which could cause cable damage.

[0014] The four corners of the moving groove are rounded to prevent the four right-angled sides of the sample holder from colliding with the moving groove.

[0015] The support frame includes: a support plate, support feet connected to the support plate, and an optical coupler fixing plate. The first elongated hole and the second elongated hole are both located on the support plate, and the position optical coupler sensor is mounted on the optical coupler fixing plate.

[0016] Using the above-described scheme, this invention provides an in vitro diagnostic emergency sample loading and transmission device. When testing an emergency sample, the sample holder is first moved to one end of the moving slot, and the sample to be tested is placed into the sample placement slot. Then, the sample holder is pushed to the other end of the moving slot. The position optocoupler sensor detects that the sample holder has reached the predetermined position, and the detection sensor also detects the presence of the sample to be tested in the sample placement slot. The in vitro diagnostic instrument can then perform the test on the sample. Since no motor-driven mechanism is used, costs are greatly reduced, and space occupancy is also minimized, making it highly practical and convenient to apply. Attached Figure Description

The sensing area of ​​the position optical coupler sensor 30 overlaps with the range of motion of the optical coupler baffle 42. The moving groove 21 provides a moving area for the sample holder 40. The position optical coupler sensor 30 determines whether the sample holder 40 has moved to a predetermined position by detecting the optical coupler baffle 42. The sample placement slot 43 is used to place a sample 90 to be tested, and the detection optical coupler sensor 41 is used to detect whether the sample placement slot 43 contains a sample 90 to be tested.

[0027] The moving groove 21 is provided with a guide slide 22, and the sample holder 40 is provided with a guide slider 44, which matches the guide slide 22. The guide slider 44 and the guide slide 22 allow the sample holder 40 to move more stably within the moving groove 21.

[0028] The in vitro diagnostic emergency sample loading and transfer device further includes a handle 50 connected to the sample holder 40, the handle 50 being positioned above the support base 20. The handle 50 allows for easy pushing of the sample holder 40.

[0029] The in vitro diagnostic emergency sample loading and transmission device further includes: an RFID reading module 60, a left cover plate 51, a right cover plate 52, and a test tube baffle 53, all mounted on the support base 20. The RFID reading module is used to read the current sample holder 40, the number of the sample 90 to be tested within the sample holder, and other information. The left cover plate 51 and right cover plate 52 are used to prevent liquid from the sample 90 to be tested from spilling into the in vitro diagnostic instrument. The test tube baffle 53 is used to assist the in vitro diagnostic instrument in sampling.

[0030] The RFID reading module 60 includes: a mounting plate 61 and a protective cover 62 connected to the support base 20, an RFID card 63, and an insulating ring 64 with its two ends abutting against the mounting plate 61 and the RFID card 63, respectively; screws pass through the RFID card 63 and the insulating ring 64 to connect to the mounting plate 61, and the protective cover 62 covers the RFID card 63. The insulating ring 64 prevents the RFID card 63 from directly contacting the mounting plate 61.

[0031] A magnet 23 is provided at one end of the moving groove 21, and an iron plate 45 is provided on the side of the sample holder 40 facing the magnet 23.

[0034] The four corners of the moving groove 21 are rounded, which can prevent the four right-angled sides of the sample holder 40 from colliding with the moving groove 21.

[0035] The support frame 10 includes: a support plate 13, support feet 14 and an optocoupler fixing plate 15 respectively connected to the support plate 13.

[0036] When testing emergency samples, the sample holder 40 is first moved to the end of the moving slot 21 away from the magnet 23. The sample 90 to be tested is then placed into the sample placement slot 43. The pusher then moves the sample holder 40 to the end of the moving slot 21 where the magnet 23 is located. The position optocoupler sensor 30 detects that the sample holder 40 has reached the predetermined position, and the detection sensor also detects the presence of the sample 90 to be tested in the sample placement slot 43. The in vitro diagnostic instrument can then perform testing on the sample 90. Because no motor-driven mechanism is used, costs are greatly reduced, and space occupancy is minimized, making it highly practical and convenient to use.

[0037] In summary, this invention provides an in vitro diagnostic emergency sample loading and transport device. When testing an emergency sample, the sample holder is first moved to one end of the moving slot, the sample to be tested is placed into the sample placement slot, and then the sample holder is pushed to the other end of the moving slot. The position optocoupler sensor detects that the sample holder has reached the predetermined position, and the detection sensor also detects the presence of the sample to be tested in the sample placement slot. Then, the in vitro diagnostic instrument can perform testing on the sample. Since no motor drive mechanism is used, costs are greatly reduced, and space occupancy is also minimized, making it highly practical and convenient to use.
