Description
Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a vacuum test tube suction volume detects with full-automatic altitude correction appearance.
Background
Currently, the current state of the art commonly used in the industry is such that:
vacuum blood collection tubes are medical instruments that are widely used in clinical tests. The nominal liquid capacity of the blood collection tube is a key technical index of the vacuum blood collection tube, and directly influences the accuracy of blood suction of the vacuum blood collection tube and influences the clinical test result.
In the detection of the nominal liquid capacity of the disposable human venous blood collection container in the industry standard YY0314-2007, the altitude correction is required when the altitude of a test site is not 0 altitude (the atmospheric pressure is 101 KPa).
The "nominal liquid volume" has historically been a high concern in quality supervision and is the most likely item to fail. For vacuum blood collection tubes used in high altitude areas, in "YY 0314-2007 disposable human venous blood collection container" (hereinafter referred to as standard), it is recommended to correct the altitude by using a vacuum method. For the sake of uniform description, hereinafter, the "corrected pressure" is used to indicate the pressure required to be reached by the lancet interface of the experimental device or the altitude corrector, and the "actual pressure" is used to indicate the actual pressure of the lancet interface of the experimental device or the altitude corrector. The recommended experimental system is to change the pressure of the self-sealing rubber piece by pumping air above the liquid reservoir through the suction device so as to simulate the pressure at the altitude to be corrected.
However, no corresponding experimental device is sold in the market at present, and the conventional experimental method is to form negative pressure by manually sucking air by using an infusion apparatus negative pressure tester or an injector; a small filter flask was used as the reservoir. Such an approach has mainly the following disadvantages:
1) because the pressure sensor of the infusion apparatus negative pressure tester is arranged in the tester and the influence of the time delay of the air channel is added, the difference between the actual pressure and the correction pressure is often large when the infusion apparatus negative pressure tester is automatically stopped, and the actual pressure and the correction pressure need to be manually adjusted for many times; the manual injector sucks air, needs the matching use of the one-way conduction valve, and needs to be repeatedly manually adjusted according to the corrected pressure intensity.
2) As the experiment proceeded, the water in the filter flask was consumed and the internal pressure varied. The manual adjustment of the injector or the negative pressure tester of the infusion apparatus cannot be dynamically adjusted. When the actual pressure intensity changes, the system can not automatically adjust the actual pressure intensity to be stabilized near the correction pressure intensity;
3) the volume of the filter flask is very small (the nominal volume is 250ml), so that each blood collection tube has a large influence on the actual pressure, and water needs to be added into the flask frequently;
4) the pipeline of the system adopts the latex tube, is easily influenced by the external atmospheric pressure, and the joint is easy to leak gas.
Due to the influence of the factors, the test is complicated, and the actual pressure and the corrected pressure have large deviation possibly, so that the final test result is influenced.
In summary, the problems of the prior art are as follows:
(1) the existing experimental device needs to be manually adjusted for many times, and is complicated;
(2) the dynamic adjustment cannot be carried out, and the actual pressure intensity cannot be automatically adjusted;
(3) the volume of the filter flask is small, so that each blood sampling tube has large influence on the actual pressure intensity, and water needs to be added into the flask frequently;
(4) the pipeline joint is easy to leak gas.
The difficulty and significance for solving the technical problems are as follows:
in the field of medical instruments, due to the fact that the audience is too small, the detection use frequency is not high, the structure is easy to build and the like, no professional team is available at present to solve the problems in the prior art. However, with the enhancement of the supervision, the inspection and detection workload for the vacuum blood collection tube increases year by year, the work efficiency is improved, and the inspection and detection resources are saved. On the other hand, the industry needs to detect the nominal liquid volume under higher precision control, reduce the interference of human factors, improve the automation degree, improve the accuracy of blood suction of the vacuum blood collection tube to the maximum extent under the condition of the prior art, and avoid clinical inspection accidents.
