A syringe flow characteristic tester

Abstract

The invention discloses an injector flow characteristic tester which comprises a host and a test machine. The host comprises a host frame, an injector clamping mechanism, a transmission mechanism, a control unit, a communication module and a power module, wherein the injector clamping mechanism, the transmission mechanism, the control unit, the communication module and the power module are mounted on the host frame, the transmission mechanism is connected with the injector clamping mechanism, the power module is connected with the control unit, the communication module and the transmission mechanism, and the control unit is connected with the communication module and the transmission mechanism. The test machine comprises a balance support, an electronic balance, a water tank and an injection needle, wherein the electronic balance is mounted on the balance support, the water tank is mounted on the electronic balance, the injection needle is mounted in the water tank through the balance support, the electronic balance is connected with the communication module through a communication wire, and the injection needle is connected with the injector clamping mechanism through a hose. The injector flow characteristic tester is simple in structure, low in cost and high in intelligence, and use efficiency of testing staff can be greatly improved.

Description

Technical field [0001] The invention relates to a flow characteristic tester, in particular to a syringe flow characteristic tester. Background technique [0002] The most important reference standard for the syringe flow characteristic tester is the measurement method of clause 50.4 in GB 9706.27-2005. At present, the domestic syringe injection pump products also use this method, and there are only syringe-driven instruments, and there is no equipment for detecting the flow characteristics of the syringe. The method of balance measurement and calculation is widely used in China to obtain parameter comparison. This method has many problems such as low automation, large measurement error, relatively cumbersome operation, low efficiency, poor compatibility, etc.; and because the drive structure is not stable, it will cause greater errors , Can not meet the measurement requirements of multi-standard syringes. [0003] Due to the unstable operation of the existing syringe flow charac...

AI Technical Summary

Problems solved by technology

In China, the method of balance measurement and calculation is generally used to obtain parameter comparison. This method has many problems such as low degree of automation, large measurement error, relatively cumbersome operation, low efficiency, and poor compatibility; and because the driving structure is not stable, it will cause greater errors. , can not meet the multi-specification syringe determination requirements

[0003] Because the existing injector flow characteristics tester does not run smoothly and has vibration during operation, the positioning accuracy is low, and it is inconvenient to clamp the injector. Real-time display of the flow characteristics of the syringe measurement. Therefore, a syringe flow characteristic tester with simple structure, low cost, high intelligence, and can greatly improve the efficiency of testing personnel is needed, but there is no report in the prior art.
