Description

Method for manufacturing speed regulating groove component

Technical field

The present invention relates to the field of medical device accessory manufacturing, and more particularly to a method of manufacturing a speed control groove component.

Background technique

At present, the speed regulating component in the infusion regulator is provided with one or more speed regulating grooves, which are equipped with a speed regulating groove whose cross-sectional area is continuously changed, or a speed regulating groove with a segmental different cross-sectional area. Because the clinical infusion has high requirements on the speed regulation accuracy of the infusion regulator, the speed regulation accuracy often depends on the cross-sectional area accuracy of the speed control groove, especially in the fine flow rate regulation, the cross-sectional area of the speed control groove is Mm ^{2 is} used as the unit of measurement.

Most of the speed control grooves adopt the open groove design. In order to avoid the unsteady plastic when pulling the mold after injection, the speed control surface is uneven. The injection mold needs to set a small angle of inclination, and the speed is adjusted after injection. The width of the groove body of the groove generally forming the speed control groove is larger than the width of the groove bottom of the same vertical section, and is generally inverted trapezoidal or semi-circular.

However, the above-mentioned speed regulating components are basically produced by injection molding after manufacturing the mold, because of the precision of the mold in the production process, the degree of mold wear, the physical and chemical properties of different batches of the same material, and the production process (such as injection temperature, mold temperature, Injection pressure, injection speed, etc., etc. all affect the accuracy of the speed control groove. Errors of 5 to 20 μm often occur, and even higher. In the fine flow control groove section, the error ratio is high. In the current infusion governor, in the case of fine flow speed regulation, the speed regulation error generally reaches more than 10%, most of the finished product errors reach 15 to 30%, and some of the finished product errors even exceed 30%, even in the same batch. of Finished products often have unstable quality conditions, posing a safety hazard. Especially in patients with heart failure, kidney failure and other factors that are very sensitive to the amount of fluid or patients who need to enter the rescue drug accurately, it is easy to cause medical accidents and even endanger the patient's life.

Because the accuracy of infusion does not meet clinical expectations, it is currently easier to implement the method of measuring the drop rate by measuring the drip rate. Therefore, the clinical infusion regulator that regulates the drip rate is still the main clinical.
