Storage device for blood routine examination waste liquid

Abstract

The invention discloses a blood routine examination waste liquid storage device, and the device comprises a storage box and a pretreatment mechanism; a laser emitter and a laser receiver are fixedly installed on the left side and the right side of the storage box respectively, and laser emitted by the laser emitter can irradiate a corresponding receiving area on the laser receiver through the interior of the storage box; four PH value measuring probes are uniformly distributed and fixed in the storage box, a heating coil is mounted in a box body at the lower half part of the storage box, a precipitate discharge port is formed in the bottom of the storage box, and a fixed block is fixedly connected to the outer wall of the precipitate discharge port. According to the storage device for the blood routine examination waste liquid, carbon dioxide and ammonia gas in the waste liquid can be rapidly discharged through the heating coil, the PH value in the storage device can be conveniently adjusted subsequently, the heating coil is started to increase the temperature of the waste liquid, the carbon dioxide and the ammonia gas in the waste liquid can be rapidly discharged, and the change of the pH value in the waste liquid caused by gas factors is avoided.

Description

technical field [0001] The invention relates to the technical field of medical waste liquid treatment, in particular to a storage device for blood routine detection waste liquid. Background technique [0002] When testing the drawn blood, it is necessary to add different testing fluids according to different testing items. Therefore, the waste fluid of blood routine testing contains bacteria, viruses, organic matter and chemical agents, and the testing waste fluid needs to be pretreated. Aerobic bacteria decompose organic matter, ozone sterilization and chemical treatment before it can be discharged into the storage device. The organic matter in the waste liquid is decomposed by aerobic bacteria to produce carbon dioxide and ammonia gas, and ammonia gas is very soluble in water. Carbon dioxide and ammonia gas Dissolving in waste liquid will change its pH value, and stirring and temperature changes in the storage device will easily lead to the separation of carbon dioxide and...

[0002] When testing the drawn blood, it is necessary to add different testing fluids according to different testing items. Therefore, the waste fluid of blood routine testing contains bacteria, viruses, organic matter and chemical agents, and the testing waste fluid needs to be pretreated. Aerobic bacteria decompose organic matter, ozone sterilization and chemical treatment before it can be discharged into the storage device. The organic matter in the waste liquid is decomposed by aerobic bacteria to produce carbon dioxide and ammonia gas, and ammonia gas is very soluble in water. Carbon dioxide and ammonia gas Dissolving in waste liquid will change its pH value, and stirring and temperature changes in the storage device will easily lead to the separation of carbon dioxide and ammonia from the waste liquid, causing the pH value of the storage device to change constantly, and the waste liquid in the storage device needs to be Use a flocculant to settle the waste, and the supernatant can be discharged directly if the index is qualified. Since the flocculant needs to be used within a suitable pH value, and the amount of waste liquid dumped into the storage device is different each time, the chemicals used are different. , will lead to a large change in the pH value in the storage device, the pH value is unstable, the flocculation and precipitation are not ideal, there will be suspended solids, and the discharge of the supernatant will cause environmental pollution
