Description

Technical Field

[0001] The utility model belongs to the technical field of IVD detection, in particular to a reagent card moving device for IVD detection. Background Art

[0002] In vitro diagnostics (IVD) refers to technologies and services that obtain clinical diagnostic information by testing human samples outside the human body. The IVD industry is a key branch of the medical device field, with its products and technologies widely used in disease prevention, diagnosis, treatment monitoring, disease course observation, and prognosis assessment.

[0003] Traditional in vitro testing equipment collects barcode information through manual scanning, fixed scanning, and indirect scanning. Manual scanning has a low degree of automation. Fixed scanning, where both the reagent card and the scanner terminal are in a fixed position, has low versatility and low scanning efficiency. Indirect scanning, on the other hand, has issues with recognition accuracy.

[0004] Most existing IVD tests use synchronous belts to transport reagent cards. The synchronous belt is driven by a controlled motor to move, and the reagent card slot is moved by the synchronous belt. Although this overcomes the defects of traditional manual testing, it requires the use of pulleys, synchronous belts, gears and other structures, resulting in large size, many parts and difficult assembly. The cost of use and manufacturing is high. In addition, due to the jitter of the synchronous belt during the transmission process, a large amount of noise will be generated in the IVD test, which will lead to unstable and inaccurate test values.

[0028] It should be noted that relational terms such as “first” and “second” are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0029] For this see Figure 1 , this embodiment provides a reagent card moving device for IVD testing, including: a base plate 1, a guide rail 2, a detection unit and a driving unit;

[0030] The left end of the guide rail 2 is installed with a first limiting structure; the right end of the guide rail 2 is installed with a second limiting structure;

[0031] A reagent card slot 21 is slidably mounted on the guide rail 2; a card insertion position detection switch 22 is mounted in the reagent card slot 21, and the card insertion position detection switch 22 is used to detect whether a reagent card is inserted into the reagent card slot 21;

[0032] The detection unit is used to collect the detection information of the reagent card and the barcode information on the reagent card; a plurality of operating stations are provided on one side of the detection unit along the sliding direction of the reagent card slot 21;

[0033] The driving unit is disposed on the base plate 1 , and the reagent card slot 21 is connected to the driving unit. The driving unit is used to drive the reagent card slot 21 to slide on the guide rail 2 .

[0034] In this embodiment, by installing a card insertion position detection switch 22 in the reagent card slot 21, and by installing a first limiting structure and a second limiting structure at the left and right ends of the guide rail 2, the automatic control of the movement of the reagent card can be achieved, which has a high degree of automation, is convenient for scanning, and can improve the detection efficiency. Specifically, the initial position of the reagent card slot 21 is set at the right end of the guide rail 2. When the user inserts the reagent card into the reagent card slot 21, the card insertion position detection switch 22 detects that the reagent card is inserted into the reagent card slot 21, and the driving unit drives the reagent card slot 21 from the right end of the guide rail. The reagent card slot 21 slides from the left end to the left end, the first limiting structure detects that the reagent card slot 21 reaches the left end of the guide rail, the driving unit reverses, and drives the reagent card slot 21 to slide from the left end to the right end of the guide rail.

Although this method can realize the transmission of the reagent card slot, it is easy to affect the detection result due to the large vibration amplitude of the synchronous belt during the rotation process, and generate a large amount of noise to interfere with the stability and accuracy of the detection value. For this reason, this embodiment provides a driving unit implementation method, and the driving unit includes: a driving motor 3, a screw rod 4, a screw rod nut 5 and a connecting piece 6; the driving motor 3 is fixedly installed on the base plate 1, and the output shaft of the driving motor 3 is fixedly connected to one end of the screw rod 4; the screw rod 4 The other end passes through the screw nut 5 and is threadedly engaged with the screw nut 5; the reagent card slot 21 is connected to the screw nut 5 through the connecting piece 6.
