Embodiment 1

[0027] Embodiment 1: A kind of blood culture instrument

[0028] Such as Figure 1-2 As shown, a blood culture instrument includes a bottle rack 1 placed in an incubator, a motor bracket 8 installed on the end plate 9 of the incubator through a linear motor fixed shaft 12, and a straight line installed on the end plate 9 of the incubator. Motor driver 13 and microprocessor. A linear motor 14 is installed in the motor bracket 8 . The bottle rack 1 is a three-layer structure. A culture bottle base 16 is detachably connected to the bottle rack of each layer of structure by bolts. The microorganism culture bottle 15 is fixedly installed on the culture bottle base 16 . The bottle rack 1 on each layer is fixedly connected with the swing frame 2 by bolts. In this embodiment, the number of swing frames 2 is three; the other end of any swing frame 2 is fixedly hinged with the swing frame sleeve rod 5 on the output end 10 of the linear motor through the output connecting shaft 11 ....

Abstract

The invention relates to a blood culture system. The blood culture system comprises a bottle rack (1) placed in a culture box, a motor bracket (8) mounted on a culture box end plate (9) through a linear motor fixing shaft (12), a linear motor driver (13) and a linear motor (14) placed in the motor bracket (8), wherein a position sensor rotor (4) is mounted on a swing frame sleeve rod (5); the position sensor promoter (4) corresponds to a position sensor stator (3) on the culture box end plate (9); the position sensor stator (3) detects the position information and speed information of the position sensor promoter (4) in real time, and sends the detected information to a microprocessor on the culture box end plate (9); the microprocessor adjusts and controls the rotation speed of the linear motor (14) in real time according to the received information. The blood culture system is simple and reasonable in structure, relatively high in rotation speed and mechanical stability, and can realize real-time process control of a swing frame.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood culture instrument. Background technique [0002] The automatic blood culture instrument consists of a constant temperature incubation system and a detection system. The traditional blood culture instrument adopts the rotating type, and the rotating blood culture instrument keeps the culture solution in the culture bottle in a state of constant shaking by rotating, and the rotating face plate of the rotating blood culture instrument has a cylindrical detection inside The holes are diffused in layers from the inside to the outside, and the detection holes in each layer are evenly distributed. Each layer is equipped with a detection position, and the blood culture bottles to be detected are searched one by one through the stepping motor. [0003] The Chinese utility model patent No. ZL201320683354.1 previously applied by the same applicant of this patent applic...
