Abstract

The invention discloses a novel infusion regulator and relates to a medical device which comprises a housing and a rolling wheel, wherein the housing is in a U-shaped groove structure, corresponding shaft holes are arranged on two sides, a convex part is arranged on the surface of the inner bottom of the housing, and the convex part is arranged below the shaft holes on the two sides of the housing; and the rolling wheel comprises a regulating wheel, circular regulating wheel pieces and a mounting shaft for mounting the shaft holes on the two sides of the housing, the circular regulating wheel pieces are respectively arranged on the left side and the right side of the regulating wheel, the mounting shaft is arranged in the position of a central shaft of the regulating wheel and the circular regulating wheel pieces, and a curved surface which is designed along the shaft center in the form of an involute and has a certain curvature change is arranged on the surface of the regulating wheel. The novel infusion regulator has the benefits of small volume, material conservation, convenient operation, stable speed and reliable regulation and has the characteristics of improving the product precision, being conducive to automatic assembly and improving the production efficiency.

Description

technical field [0001] The invention relates to a medical device, in particular to a transfusion speed regulator used for intravenous supplementation of medicinal fluid or fluid therapy. Background technique [0002] At present, the commonly used method to control the infusion speed in clinical practice at home and abroad is to install an inclined-plane regulator with movable rollers in the inclined slide on the outside of the infusion catheter. The rollers roll on the bottom surface of the inclined surface to change the cross-sectional area of ​​the catheter to adjust Infusion speed; however, due to its design, there are multiple turns in the shell structure, and its typical structure is shown in figure 1 : The housing 1 and the roller 2 form a roller inclined-plane regulator, the shaft of the roller 2 rolls in the transverse chute provided by the housing 1, and rolls the infusion catheter on the inclined bottom surface 12 of the housing 1 to realize changing the catheter ...
