An adaptive bathing specimen collection box

Abstract

The invention discloses an adaptive bathing specimen collection box. The adaptive bathing specimen collection box comprises a bathing box and a connecting sleeve; a displacement sensor includes a variable resistance slide rail and a magnetic suction type slip ring, and the variable resistance slide rail is arranged On the inner wall of the specimen chamber, a magnetic slip ring is slidably arranged on the variable resistance slide rail; the liquid level assembly includes a liquid level plate and a liquid level plate driving device. The level plate driving device is arranged at the bottom of the cold storage space, the liquid level plate driving device is connected with the liquid level plate, and drives the liquid level plate to move up and down along the cold storage space; the connecting sleeve is connected to the outer wall of the shower box, and the connecting sleeve is provided with a main The control chip is electrically connected with the displacement sensor and the liquid level plate driving device respectively. In the embodiment of the present invention, in the self-adaptive bathing specimen collection box, the liquid level height of the cooling liquid can be adaptively adjusted according to the length of the specimen, which has good practicability.

Description

technical field [0001] The invention relates to the technical field of specimen collection and preservation, in particular, to an adaptive bathing specimen collection box. Background technique [0002] The specimen refers to the container used to collect blood gas samples. The blood gas samples should not be placed below room temperature (25 degrees Celsius) for more than 15 minutes. Otherwise, the blood gas results measured by the blood gas samples will deviate, resulting in pH and pO 2 will decrease, pCO 2 and lactic acid will increase; studies have shown that storing blood gas samples in a mixture of ice and water (about 4 degrees Celsius) can prolong the storage time of blood gas samples from no more than 15 minutes to no more than 30 minutes; the existing specimen collection boxes, generally The specimen is kept cold by adding a cooling liquid to appropriately prolong the storage time of the blood gas sample in the specimen. [0003] In practical applications, due to ...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, due to the different lengths of the specimens, specimens of different lengths enter the specimen collection box at different depths. When encountering specimens with shorter lengths, it is necessary to add a large amount of cooling liquid to the specimen collection box In the box, make the liquid level of the cold-preserving liquid higher than the specimens entering the specimen collection box, so that the cold-preservation liquid surrounds the specimens entering the specimen collection box, so as to ensure the cold preservation effect of the specimens; it can be seen that in the existing In the sample collection box, the liquid level of the cold storage liquid is controlled by the amount of the cold storage liquid added, and the liquid level of the cold storage liquid cannot be adjusted adaptively according to the length of the sample, which has certain disadvantages
