Embodiment 1

[0038] Such as Figure 5As shown, the pressure pipe valve is a pneumatic pressure pipe valve. The rubber hose passes through the pressure tube valve 2 to connect the reaction cell 1 and the optical measurement module. The part of the rubber hose that passes through the pressure tube valve 2 is a soft rubber hose with good resilience and is not easy to age, such as a Pharmed tube. The air chamber 21 of the pressure tube valve 2 is connected to the common end of the electromagnetic three-way valve LV1 through a rubber tube, the normally open end of the electromagnetic three-way valve LV1 is connected to compressed gas, and the normally closed end of the electromagnetic three-way valve LV1 is connected to the atmosphere. The electromagnetic three-way valve LV1 is turned on and off so that the air chamber 21 of the pneumatic pressure tube valve 2 is connected to compressed gas or atmosphere. When the electromagnetic three-way valve LV1 is powered off, the compressed gas enters th...

Embodiment 2

[0040] Such as Figure 6 As shown, the pressure pipe valve is a pneumatic pressure pipe valve. The rubber hose passes through the pressure tube valve 2 to connect the reaction tank 1 and the waste liquid module. The part of the rubber hose passing through the pressure tube valve 2 is a soft rubber hose with good resilience and is not easy to age, such as Pharmed tube. In order to prevent the sample mixture in the reaction cell 1 from falling due to gravity, in this embodiment, the hose from the reaction cell to the pneumatic pressure tube valve is arranged in a downward arc structure 3 . The air chamber 21 of the pressure tube valve 2 is connected to the common end of the electromagnetic three-way valve LV1 through a rubber tube, the normally open end of the electromagnetic three-way valve LV1 is connected to compressed gas, and the normally closed end of the electromagnetic three-way valve LV1 is connected to the atmosphere. The electromagnetic three-way valve LV1 is turned ...

Abstract

The invention discloses a device for uniformly mixing test samples in an analysis meter reaction tank. The device comprises a reaction tank, an optical measurement module and a rubber tube connected with the reaction tank and the optical measurement module, wherein a plurality of reagent inlets are formed in the reaction tank, a waste liquid hole is designed right below the reaction tank, a samplechannel is designed in the position close to the bottom of an inner cavity of the reaction tank below the regent hole, the reagent inlet is used for adding an regent into the reaction tank, the wasteliquid hole is connected with a waste liquid module, and the sample channel is connected with the optical measurement module through a pipeline; and a pressure pipe valve is arranged on the rubber tube connected with the reaction tank and the optical measurement module and is used for absorbing sample liquid out of the reaction tank or pushing the sample liquid into the reaction tank for severaltimes through compressing or loosening the rubber tube for several times. The device provided by the invention is easy to operate and simple in structural design of the reaction tank and is good in uniform mixing effect. The invention further discloses a method for uniformly mixing the samples.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a mixing device and method for test samples in an analyzer reaction pool. Background technique [0002] Existing medical devices involving liquid pipeline systems, that is, devices that absorb the samples to be tested and add them to the internal reaction pool (cup) for reaction and incubation before performing relevant parameter tests, such as hematology analyzers, automatic chemiluminescence immunoassay analyzers , automatic biochemical instrument, etc., need to add the sample into the reaction pool, in order to fully react and ensure the accuracy and repeatability of the instrument test results, the sample and the corresponding reagent must be mixed after mixing, and the degree of mixing directly affects The accuracy and repeatability of test results. At present, there are three methods used in instruments to mix samples and corresponding reagent mixtures: bubble mixing, stirri...
