Description

Technical Field

[0001] The utility model belongs to the field of blood culture instruments, in particular to a multi-hole position temperature parallel measurement device for a blood culture instrument. Background Art

[0002] Blood culture is a microbiological test used to test for the presence of bacteria in blood samples. When performing blood culture, the blood sample needs to be placed in a blood culture bottle and incubated with continuous and uniform shaking at a suitable temperature to promote better bacterial growth, thereby improving the accuracy of the test results.

[0003] After searching, a Chinese patent discloses a multi-hole position temperature parallel measurement device and a blood culture instrument (authorization announcement number CN 213113325 U). The patented technology includes multiple columnar bodies that match the culture holes of the incubation module in the blood culture instrument, and columns and temperature measuring circuit boards arranged inside the columnar bodies. One end of the column is fixedly connected to the bottom wall of the columnar body, and the temperature measuring circuit board is fixedly connected to the other end of the column; a temperature measuring probe for temperature detection is provided on the temperature measuring circuit board, and the columns in the multiple columnar bodies have the same or different heights, so that different temperature measuring probes can detect temperature information of the same depth or different depth areas at different culture holes. The device provided by the utility model can simultaneously perform parallel temperature measurement on culture holes at different positions, and can measure the temperature at different depths inside the hole, comprehensively and accurately reflecting the operation control status of the blood culture system.

[0004] Although this technology allows the probe to measure the temperature of different depths in the culture well through columns of different heights, the columns in the device are fixed by studs. Therefore, when the measuring position of the temperature probe needs to be adjusted, the studs need to be frequently loosened and tightened and the columns need to be replaced, which is very troublesome to adjust. In addition, due to the large number of culture wells, it is more time-consuming and labor-intensive to adjust multiple temperature probes, which is not conducive to improving measurement efficiency.

[0023] Specifically, the transmission assembly includes a first lead screw 9 and a lifting unit. The first lead screw 9 is equidistantly rotatably connected to the inside of the side plate 3. The external thread of the first lead screw 9 is connected to a first thread block 10. The first thread block 10 is slidably connected to the inner wall of the side plate 3. The shift block 8 is fixedly connected to the outer side of the first thread block 10 and extends to the outside of the side plate 3. The top of the first lead screw 9 is fixedly connected to a first bevel gear 11. The upper part of the interior of the fixed frame 4 is rotatably connected to a rotating rod 12.
