Abstract
The utility model relates to an analysis chamber used for a blood gas analyzer, which is formed by passing a W-shaped pipeline through an inclined hole processed on a measuring chamber and a round hole used for placing a measuring electrode film. The diameter of the pipeline is d, the diameter and the depth of the round hole for placing the electrode film are respectively D and h, an included angle between the pipeline center line and the round hole center hole is beta, the parameter D of the analysis chamber is between phi 2.9 and phi 3.5mm, h is between 0.8 and 1.0mm, d is between 0.7 and 0.9mm, and beta is between 50 degrees and 70 degrees. Through the improvement on the parameter of the original analysis chamber, the improved analysis chamber has the advantages that air bubbles can not be easily generated, the flushing is cleaner, and in addition, the accuracy and the precision of the blood gas analyzer can be improved.
Description
Technical field:
The utility model relates to blood gas analyzer, especially a kind of analysis room that is used for blood gas analyzer.
Background technology:
For blood gas analyzer, in many places the medium in the pipeline is carried out different measurements for convenient, pipeline is processed into the W type by certain angle, be provided with potential electrode at the top of W type pipeline, this W type pipeline not only can be saved the space, and is not easy to produce bubble, easier rinsing well.
Particularly, the existing analysis room's major parameter that is used for blood gas analyzer is: D=(φ 3.7～φ 3.8) mm, h=(0.5～0.6) mm, d=(0.7～0.9) mm, β=45 °～60 °.
The accuracy that the prior art instrument can reach, precision are:
The existing in prior technology problem: be easy to generate bubble in analysis room's pipeline, pipeline is not easy to rinse well, and accuracy, the precision of instrument are poor.
The utility model content:
The purpose of this utility model provides a kind of analysis room that is used for blood gas analyzer, adopts the pipeline of W type, and this pipeline can carry out different measurements to the medium in the pipeline in many places.
Concrete technical scheme is: a kind of analysis room that is used for blood gas analyzer, with W type pipeline by the inclined hole on measuring chamber, processed and place the circular hole that the potential electrode film uses and form, d is the diameter of pipeline, D and h are respectively and place diameter and the degree of depth of electrode film with circular hole, and β is the angle of pipeline center line and circle hole centreline; Described D=(φ 2.9～φ 3.5) mm, h=(0.8～1.0) mm, d=(0.7～0.9) mm, β=50 °～70 °.Wherein, thereby the h value cause easily too greatly flushing totally with cause pipeline in medium can not fully contact with electrode film and influence measurement result, the too little electrode film that then damages easily of h, the β value is too for a short time be not easy flushing of pipeline clean, the large increase of β value required medium consumption in the pipeline.
The utility model is that pipeline is processed into W type shape by certain angle, top at W type pipeline is provided with potential electrode, and this pipeline can carry out different measurements to the medium in the pipeline in many places, has saved the space of pipeline greatly, and can make pipeline be not easy to produce bubble, easier rinsing well.And accuracy, the precision of raising blood gas analyzer.
Description of drawings:
Fig. 1 is Fig. 1 of the present utility model analysis room structural representation.
As shown in the figure, d is the diameter of pipeline, and D and h are respectively diameter and the degree of depth of discharge electrode film with circular hole, and β is the angle that pipeline center line and discharge electrode film are used circle hole centreline.
Embodiment:
Embodiment 1
A kind of analysis room that is used for blood gas analyzer, with W type pipeline by the inclined hole on measuring chamber, processed and place the circular hole that the potential electrode film uses and form, d is the diameter of pipeline, and D and h are respectively and place diameter and the degree of depth of electrode film with circular hole, and β is the angle of pipeline center line and circle hole centreline.The parameter of analysis room is D=(φ 2.9～φ 3.5) mm, h=(0.8～1.0) mm, and d=(0.7～0.9) mm, β=50 °～70 °, the degree of accuracy that the instrument after the improvement can reach, accuracy are:
Thereby the h value cause easily too greatly flushing totally with cause pipeline in medium can not fully contact with electrode film and influence measurement result, the too little electrode film that then damages easily of h, the β value is too for a short time be not easy flushing of pipeline clean, the large increase of β value required blood consumption during test.Improve by the parameter to former analysis room, the analysis room after the improvement not only pipeline is not easy to produce bubble, washes totallyer, and has improved accuracy, the precision of blood gas analyzer.
