Abstract
The utility model relates to a speed governing switch used for an infusion set, which comprises a framework (1) and a speed governing bolt (2) which are arranged on a perfusion tube (3), wherein, the framework (1) is provided with a bolted hole in which the speed governing bolt (2) is arranged, the end surface of the lower part of the speed governing bolt (2) is a crown face. The speed governing switch has the advantages of convenient operation and accurate speed adjustment, and is particularly suitable for being used in transfusion locations with serious requirements for the transfusion speed.
Description
Technical field
This utility model relates to a kind of medical infusion utensil, particularly a kind of transfusion device speed-regulating switch.
Background technology
The speed-regulating switch of existing transfusion device is a roller structure, comprises framework and roller, and skewed slot is offered in the framework both sides, and roller places in the skewed slot by axle, and rotation roller moves may command to the depression degree of tube for transfusion along skewed slot, thereby regulates transfusion speed.The problem that exists is: operation control is not easily, when particularly transfusion speed being finely tuned, needs carefully rotation roller, is difficult to control rotation dynamics, is difficult to reach the requirement of fine adjustment speed yet.
Summary of the invention
The purpose of this utility model is to provide a kind of above-mentioned shortcoming, easy to operate, speed governing transfusion device speed-regulating switch accurately that overcomes.
This utility model is achieved in that a kind of transfusion device speed-regulating switch, comprises the framework and the droop adjustment screw that are arranged on the tube for transfusion, and screw is set on the framework, and droop adjustment screw places in the screw, and the end face of droop adjustment screw bottom is an arc surface.
This utility model has changed the structure of prior art speed-regulating switch, adopts screw thread rotation to depress mode and regulates drafts, and have and control convenient, speed governing advantage of uniform, when particularly needing to finely tune transfusion speed, adjusting that can be more accurate.
Description of drawings
Accompanying drawing is a cross-sectional schematic of the present utility model.
Among the figure, 1, framework, 2, screw, 3, tube for transfusion.
The specific embodiment
As shown in the figure, droop adjustment screw 2 places in the screw of framework 1, and the end face that droop adjustment screw 2 bottoms contact with tube for transfusion 3 is an arc surface.During use, screw screw 2 downwards and can compress tube for transfusion 3, reduce transfusion speed, otherwise can increase transfusion speed.
Compared to existing technology, this utility model operation control is more convenient, accurate, is specially adapted to transfusion speed is had the transfusion place of strict demand.
Claims (1)
1, a kind of transfusion device speed-regulating switch is characterized in that: comprise the framework (1) and the droop adjustment screw (2) that are arranged on the tube for transfusion (3), framework is provided with screw on (1), and droop adjustment screw (2) places in the screw, and the end face of droop adjustment screw (2) bottom is an arc surface.
