Automatic implantation type blood culture instrument

Abstract

The invention relates to equipment for carrying out bacterial culture and automatic implantation on a blood sample and particularly relates to an automatic implantation type blood culture instrument. According to the automatic implantation type blood culture instrument, three culture tanks are arranged, a first culture tank is used for arranging blooding culture bottles and corresponding detection devices, and a streak inoculation site, a delivery mechanical arm and a streak mechanical arm are arranged among the first culture tank, a second culture tank and a third culture tank, so that the timed implantation capacity of a positive sample is greatly improved. Compared with products in the prior art, the automatic implantation type blood culture instrument has the characteristics that by virtue of the delivery mechanical arm and the streak mechanical arm, the streak inoculation and isolated culture procedures of a positive blood sample can be automatically finished by the instrument; the implantation of the positive sample is realized under a culture environment, and the timed implantation capacity of the sample is improved; by implanting the sample to a solid culture medium under the culture environment, the positive rate of the implantation is increased; the labor force of professionals in a microbiological lab is liberated, and the blood culture quality is improved.

Description

technical field [0001] The patent of the present invention relates to a device for bacterial culture and automatic seed transfer of blood samples, in particular to an automatic seed transfer blood culture apparatus. Background technique [0002] Bacterial cultures are often performed on blood samples from patients in hospital clinical and medical research trials. The blood culture instruments on the market now put blood samples into blood culture bottles and put them into the incubator for bacterial culture. When bacteria are present in the blood, the bacterial metabolite CO 2 Reacts with moisture in blood culture bottles to produce H + or HCO 3 - Ion, an indicator or fluorescent substance is placed in a specific part of the bottle, and the instrument is equipped with a color detection device and a fluorescence detection device. When there is bacterial growth in the blood sample, the detection device captures the information and alarms, prompting the operator to perform ...

Problems solved by technology

The advantage of this method is that it can quickly and timely capture bacterial growth information, but it also has the following defects: First, the production process of consumables, namely blood culture bottles, is complicated, resulting in high prices for culture bottles; second, CO is produced during the bacterial growth process. 2 The accumulation of these gases will lead to an increase in the pressure in the culture bottle. When the laboratory operator needs to ope
