Blood culture instrument

Abstract

The invention relates to a blood culture instrument comprising a fixing frame (13), a swinging frame (8), a motor (4) and a speed reducer (5), wherein the fixing frame (13) is arranged on a base (12); the swinging frame (8) is articulated in the fixing frame (13), and the motor (4) and the speed reducer (5) are fixedly arranged on the base (12); the swinging frame (8) is of a hollow rectangle structure, the swinging frame (8) is arranged in the fixing frame (13) in a swinging manner, a first connection rod (6) is articulated with the swinging frame (8) through a second connection rod (7) on the swinging frame (8) and is also articulated on the speed reducer (5); an optical detection sensor is arranged on the swinging frame (8) and swings along the swinging of the swinging frame (8). Therefore, according to the blood culture instrument disclosed by the invention, a situation of inaccurate detection caused by nonalignment in the movement of the motor and difference in positions of detection holes is avoided; in addition, each detector is mutually independent, and the position of each detector is found out without depending on the movement of the motor, so that the time required by the movement of the motor is saved, and the detection speed is increased.

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. ZL201220738836.8 previously applied by the same applicant of this patent applic...

Problems solved by technology

[0004] In order to overcome the defects and deficiencies in the above-mentioned prior art, the present invention provides a swing-type blood culture instrument. The detection device in the blood culture instrument swings with the swing of the pendulum to avoid inaccurate movement of the motor and the detection of holes. The inaccurate detection caused by the position difference, and each detection device is independent of each other, does not need to rely on the motor to find the position, which saves the time required for the motor to move and speeds up the detection speed
