Sputum sample preservation equipment in pathological diagnosis for infectious disease research

Abstract

The invention belongs to the technical field of sample preservation, and discloses sputum sample preservation equipment in pathological diagnosis for infectious disease research, which comprises a sealing box, a sealing plate is movably hinged to the side surface of the sealing box, a sealing cover is fixedly connected to the top of the sealing box through a bolt, and a low-temperature shaft is movably connected to the bottom of the inner cavity of the sealing box. And the top of the low-temperature shaft is fixedly connected with a connecting shaft. Through the sealing box, the sealing plate, the sealing cover and the low-temperature shaft, the interior of the sealing box can be of a sealing structure under the cooperation of the sealing box, the sealing plate and the sealing cover, a worker can conveniently and rapidly take out part of sterile pipes through the sealing plate, and loss of low-temperature gas in the sealing box can be reduced; the sterile pipes are evenly distributed on the periphery of the low-temperature shaft, so that loss of low-temperature airflow of the low-temperature shaft during flowing can be avoided, and it is ensured that low-temperature gas overflowing out of the low-temperature shaft makes contact with all the sterile pipes in time.

Description

technical field [0001] The invention belongs to the technical field of sample preservation, in particular to a device for preserving sputum samples in pathological diagnosis for infectious disease research. Background technique [0002] Pathological diagnosis is to study the cause of the disease, understand the pathogenesis and understand the morphological structure of the diseased body, the change of functional metabolism and the outcome of the disease in the course of the disease, so as to provide the necessary theoretical basis and basis for the diagnosis, treatment and prevention of the disease. The basis of practice; and the basis of pathological diagnosis is usually to collect samples and carry out step-by-step inspection on the samples to obtain relevant data and pathological conditions. [0003] At present, medical samples are often stored or transported for the use of medical samples, and although the existing storage equipment can also achieve the effect of storage...

AI Technical Summary

Problems solved by technology

[0003] At present, medical samples are often stored or transported for the use of medical samples, and although the existing storage equipment can also achieve the effect of storage or transportation, due to the need to keep appropriate and low during the storage or transportation of medical samples The low temperature requires cooling equipment, but the existing cooling equipment will lose part of the cold air during use, which will lead to a decrease in cooling efficiency, and the rate of low temperature loss in different environments is different, which will cause staff It is difficult to adjust the cooling time according to the actual environment, which makes it difficult for the staff to control the environmental changes inside the thermal insulation equipment more timely and effectively, which will cause certain damage to the medical samples stored inside

[0004] Moreover, since the low-temperature cooling is released from the cooling device, it is impossible to cool the sample from around the sample at the same time, which will lead to uneven heating of the surface of the sample when it is cooled, which may have an impact on the microorganisms inside the sample, and finally make the same inside. Microorganisms produce different physiological stress responses, which may affect the original properties of the sample

[0005] At the same time, since multiple samples are usually stored in the storage device at the same time, when one or more samples are taken out, the internal environment of the storage device will change greatly. Therefore, when some samples are taken, it will affect the remaining samples, and it is necessary to adjust the equipment to make it reach the required constant temperature again, which will not only increase energy consumption, but also increase the tedious work of the staff degree
