Abstract

The invention discloses a speed-regulating groove component which comprises a body, wherein speed-regulating grooves of different pore sizes are formed in the body; a tank body is arranged on the speed-regulating grooves; and dislocation sections in different planes and / or different circle centers and / or different angles and / or different sections with the tank body are arranged on the speed-regulating grooves. According to the dislocation sections, a support on a sealing gasket can be formed, the possibility of enabling the sealing gasket to protrude into the speed-regulating groove with deformation can be reduced, and the influence of the protrusion of the sealing gasket into the speed-regulating groove with deformation on the actual liquid flow passing cross sectional area of the speed-regulating groove is further reduced. According to a non-contact processing manner, the process influence in the injection molding process can be reduced, the cutting and punching precision can be ensured on most of the materials, and stable quality is maintained. The speed-regulating groove component disclosed by the invention is applied to the fields of medical equipment fittings and medical equipment.

Description

technical field [0001] The invention relates to the field of medical device accessories and medical devices, in particular to a component as a speed regulating groove. Background technique [0002] At present, the speed-regulating parts in the infusion regulator are provided with one or more speed-regulating grooves, which are equipped with speed-regulating grooves with continuously changing cross-sectional areas; or are equipped with segmental speed-regulating grooves with different cross-sectional areas. Because clinical infusion requires high speed regulation accuracy of the infusion regulator, and the speed regulation accuracy often depends on the accuracy of the cross-sectional area of ​​the speed regulation groove, especially in fine flow speed regulation, the cross-sectional area of ​​the speed regulation groove is greater than or equal to µm 2 as a unit of measurement. [0003] Most of the speed regulating grooves adopt open groove design. In order to avoid uneven ...
