Self-adaptive bath specimen collection box

Abstract

The invention discloses a self-adaptive bath specimen collection box. The self-adaptive bath specimen collection box comprises a bath box and a connecting sleeve; a displacement sensor comprises a variable resistance sliding rail and a magnetic attraction type sliding ring, the variable resistance sliding rail is arranged on an inner wall of a specimen cavity, and the magnetic attraction type sliding ring is arranged on the variable resistance sliding rail in a sliding mode; a liquid level assembly comprises a liquid level plate and a liquid level plate driving device, the liquid level plate is embedded in a cold insulation space, the liquid level plate driving device is arranged at a bottom of the cold insulation space, and 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 insulation space; the connecting sleeve is connected to an outer wall of the bathing box, a main control chip is arranged on the connecting sleeve, and the main control chip is electrically connected with the displacement sensor and the liquid level plate driving device. According to embodiment of the invention, inthe self-adaptive bath specimen collection box, a liquid level height of a cold insulation liquid can be self-adaptively adjusted according to a length of the specimen, so that the self-adaptive bathspecimen collection box has good practicability.

Description

technical field [0001] The invention relates to the technical field of sample collection and preservation, in particular to an adaptive bathing sample collection box. Background technique [0002] Specimen refers to the container used to collect blood gas samples. The blood gas samples should not be placed under room temperature conditions (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 an ice-water mixture (about 4 degrees Celsius) can extend the storage time of blood gas samples from no more than 15 minutes to no more than 30 minutes; the existing sample collection box, generally Keep the sample cold by adding cold-preservation liquid to properly prolong the storage time of the blood gas sample in the sample. [0003] In practical applications, due to the different...

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
