Blood culture bottle having horizontal position convenient to calibrate

Abstract

The invention discloses a blood culture bottle having a horizontal position convenient to calibrate, and relates to the technical field of medical devices. The blood culture bottle having the horizontal position convenient to calibrate includes a base plate; two sides of the top of the base plate are each fixedly provided with a cover body, the top of the base plate is fixedly provided with guiderods, the bottom ends of the guide rods are located in the cover bodies, the tops of the guide rods penetrate the cover bodies and extend to the upper sides of the cover bodies, and the tops of the guide rods are fixedly connected with a fixed plate; the top of the base plate is rotationally provided with threaded rods, and the bottom ends of the threaded rods are located in the cover bodies, andthe two threaded rods and the two guide rods are arranged. The top ends of the threaded rods penetrate the cover bodies and extend to the upper sides of the cover bodies. The threaded rods and the cover bodies are rotationally connected, the threaded rods and the bottom of the fixed plate are rotationally connected, and a handle is rotationally arranged on the outer wall at one side of each coverbody. The horizontal position of a Petri dish body can be adjusted, the operation is convenient, and improvement of the working efficiency of the staff is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood culture bottle which is convenient for calibrating the horizontal position. Background technique [0002] Blood culture is a method of inoculating fresh isolated blood samples on nutrient medium, under certain conditions such as temperature and humidity, to grow and reproduce bacteria with high nutritional requirements, and to identify them, so as to determine the pathogenic bacteria. artificial cultivation method. Blood culture is an important method for clinical diagnosis of sepsis, and a positive result has extremely high application value for definite diagnosis and symptomatic treatment. However, according to literature reports, the positive rate of blood culture in China is only 17.8% and 18.4%. In order to increase the positive rate of blood culture and objectively reflect the actual situation of pathogenic bacteria in the blood of patients with sepsis...

Problems solved by technology

[0003] In the actual work process, in order to ensure the normal production and reproduction of bacteria in the blood sample, it is necessary to make the petri dish in a horizontal position so that the blood in the petri dish can be spread out evenly; when it is necessary to temporarily observe the blood sample in the petri dish Sometimes, the petri dish needs to be taken out and placed under a magnifying glass for observation, which is cumbersome to operate, and even the observation data of the blood sample will be affected to a certain extent due to shaking in the middle
