Problems solved by technology

[0002] Infusion is a relatively common treatment method for treating diseases. The flow rate control during the infusion process is generally roughly controlled by a governor formed by a wedge-shaped chute and a speed-regulating roller. The flow rate of the infusion liquid cannot be accurately controlled, and because the wedge With the existence of grooves, the speed regulating roller is unstable and prone to slipping, resulting in an instantaneous accelerati

Abstract

The invention discloses an infusion control valve. The infusion control valve comprises a cylindrical flow limiting tube sleeve and a cylindrical adjusting tube and is characterized in that a flow control plate is fixed in the section direction inside the middle section of the flow limiting tube sleeve, the flow control plate is provided with a plurality of infusion holes, the adjusting tube is nested into the flow limiting tube sleeve, a rotary handle is arranged on the lateral wall of the adjusting tube, a flow adjusting groove for accommodating the rotary handle is arranged in the flow limiting tube sleeve, the adjusting tube can rotate by using the cylindrical center of the flow limiting tube sleeve as the axis, the radial direction of the adjusting tube is provided with a flow adjusting plate, the flow adjusting plate is provided with a plurality of liquid inlets, and two ends of the flow limiting tube sleeve are provided with connectors for being connected with an infusion tube.The infusion control valve is capable of accurately controlling infusion flow speed and guaranteeing flow speed stability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion control valve. Background technique [0002] Infusion is a relatively common treatment method for treating diseases. The flow rate control during the infusion process is generally roughly controlled by a governor formed by a wedge-shaped chute and a speed-regulating roller. The flow rate of the infusion liquid cannot be accurately controlled. Due to the existence of grooves, the speed regulating roller is unstable and prone to slipping, resulting in an instantaneous acceleration of the flow rate of the liquid medicine and causing discomfort to the patient. [0003] Furthermore, it is sometimes necessary to connect different infusion tubes, but in the prior art, the joints of the infusion tubes are fixed and unstable, which can easily cause the infusion tube to fall off, the medicinal liquid to flow out, and cause waste of medicine, and even because the infus...
