Safe infusion flow speed regulator

Abstract

The invention discloses a safe infusion flow speed regulator. The speed regulator comprises a transparent speed regulator shell, an upper stop block and a lower stop block are symmetrically fixed on two sides of a through hole in the transparent speed regulator shell, and an infusion tube penetrates through the through hole between the upper stop block and the lower stop block; the side, away fromthe lower stop block, of the transparent speed regulator shell is provided with an operation opening; a first rack movably penetrates through the operation opening, and an operation handle is fixed to the side, away from an inner cavity of the transparent speed regulator shell, of the first rack; the first rack is movably provided with a driving gear, a nut base is movably arranged on a screw rod, and a threaded rod is fixedly arranged on the side, far away from a third connecting rod, of a driven gear; an adjusting abutting block is fixed at the end, away from the driven gear, of the threaded rod. The safety infusion flow speed regulator is capable of accurately controlling the dripping speed and is easy to adjust; after adjustment, medical staff can draw away the operation handle so that other people can be prevented from randomly adjusting the dripping speed; the speed regulator can be repeatedly used, so that the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a safe transfusion flow speed regulator. Background technique [0002] At present, most of the existing infusion flow rate regulators are roller-type governors. In use, due to the smooth surface and high toughness of the infusion tube, when the gear is used to squeeze the infusion tube, the gear and the infusion tube often slide relative to each other, resulting in The speed regulation is inaccurate, and the infusion tube often bounces back the gear, which is inconvenient to use; the infusion speed of many diseases needs to be strictly controlled, and the infusion speed of some medicines is too slow to affect the curative effect, and the infusion speed of some medicines is too fast. The occurrence of safety incidents, so the infusion rate cannot be adjusted at will. Although the nurse has repeatedly instructed, it is often still adjusted at will; the governor can only be...

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The device needs to use motors and solar panels to store electricity, so it needs to replenish electricity regularly, and it cannot be used normally in an environment with insufficient light or no electricity. The range is limited; 2. Both the doctor and the patient can adjust the flow rate when the device is in use, and the infusion speed of many diseases needs to be strictly controlled, so the device lacks the safety guarantee to prevent the patient from adjusting at will
