Interesting speed regulator for infusion tube

Abstract

The invention relates to an interesting speed regulator for an infusion tube. The interesting speed regulator for the infusion tube comprises an airtight switch, a liquid inlet end, a liquid outlet end and a shell body made of hard transparent materials; a cake-shaped round face of the shell body is parallel to the connecting line of the liquid inlet end and the liquid outlet end; a ratchet parallel to the round face of the shell body is arranged in the shell body, and a linkage rotary shaft fixedly connected with the ratchet penetrates through the circle center of the shell body and extends out of the shell body; the end, extending out of the shell body, of the linkage rotary shaft is provided with an arc friction disk in a clamped mode, a slide block is fixed to the friction disk, and the slide block can slide along a slide groove formed in the shell body. The speed regulator displays the flow rate visually, speed regulation is accurate, high interest is achieved, attentions of children can be effectively transferred, and the boring sense of infusion is relieved.

Description

technical field [0001] The invention relates to a medical product accessory, in particular, a speed regulator for infusion tubes. Background technique [0002] The common infusion tube is a drip hose, and the governor of this infusion tube is a gear squeeze governor. There is also a thick cylindrical cavity on this infusion tube, and the liquid flowing from the infusion bottle drops to After the cylindrical cavity enters the lower section of the infusion tube, the speed of the infusion can be known by observing the drop frequency in the cylindrical cavity; When the infusion tube is squeezed, the gear and the infusion tube often slide relative to each other, resulting in inaccurate speed regulation, and the infusion tube often bounces the gear back; during the infusion process, people will continue to observe the infusion speed. If the movement is too monotonous, it is easy to make people feel bored and anxious, and affect the patient's mood; especially children, they ofte...
