Pen type insulin syringe detection pretreatment equipment

Abstract

The invention discloses a pen-type insulin injector detection pretreatment driving tool, which belongs to the technical field of medical equipment inspection, and its structure includes a rotation system and a linear motion system. Carry out linear motion; the rotary system includes a chuck, the front of the chuck is used to clamp the pen-type insulin syringe, and the rear of the chuck is connected to the first rotary drive mechanism; the linear motion system includes a linear guide rail and a slider, and the top of the slider and the rotary system Fixed connection, the bottom of the slider is movably installed on the linear guide rail and can move along the linear guide rail. The technical scheme of the example of the present invention can drive the pen-type insulin syringe to rotate and advance, assist the pretreatment before the injection dose accuracy inspection, save manpower and improve efficiency.

Description

technical field [0001] The invention relates to the technical field of medical device inspection, in particular to a pen-type insulin syringe detection pretreatment device, which is especially suitable for pretreatment before the dose accuracy inspection of the pen-type insulin syringe. Background technique [0002] In recent years, the incidence of diabetes has been increasing year by year, and the incidence tends to be younger. With the gradual deepening of people's understanding of diabetes, the important position of insulin in the treatment of diabetes has been further determined, the use of insulin has become more extensive, more and more patients are using insulin, and more and more insulin products are available. It is widely used because of its accurate injection dose, simple operation and convenient portability. [0003] The pen-type insulin syringe consists of a dose adjustment button, a pen body, a release button, a lead screw, a refill holder, and a pen cap. ...

Problems solved by technology

[0005] How to ensure the dosage accuracy of the pen-type insulin syringe has become a difficult problem today. The inventor found in many years of work and research that before the dosage accuracy test of the life test, the pretreatment of the life test of the pen-type insulin syringe is mainly to complete the simulation. The injection process of the insulin pen, including the rotation and injection process, the simulation action is complex, and the number of simulations needs to be 1.5 times the expected number of times, generally 3000 to 5000 times. The stability of the simulation test can greatly guarantee the test results accuracy and reliability, but if the preprocessing work is only done manually, the workload will be huge and the efficiency will be low. In addition, manual operation is difficult to ensure the consistency of the strength every time, and the stability and reproducibility are not good.
