Liquid medicine conveying device for clinical medical treatment

Abstract

The invention provides a liquid medicine conveying device for clinical medical treatment. A hard control tube section is arranged on a rubber tube, a liquid guide hole communicating with the rubber tube is formed in the control tube section, a mounting tube is fixedly connected to one side of the control tube section, one end of the mounting tube is open, and the other end of the mounting tube isclosed; a valve plate comprises a sliding block and a sliding plate which are integrally connected, an elastic ball for driving the sliding plate comprises a left ball shell and a right ball shell, the right ball shell is made of elastic materials, the left ball shell is made of hard materials, an opening is formed in the end, facing the sliding plate, of the left ball shell, a mounting rod is vertically and fixedly connected in the left ball shell, a horizontal take-up lever is vertically and fixedly connected to the mounting rod, a parallelogram-shaped four-bar mechanism is arranged in the right ball shell, an upper hinge point and a lower hinge point of the four-bar mechanism are connected to the inner top wall and the inner bottom wall of the right ball shell respectively, and a left hinge point and a right hinge point of the four-bar mechanism are located in strip grooves respectively and can linearly slide in the strip grooves. The liquid medicine conveying device for clinical medical treatment is extremely convenient to use, has double valve control, and can prevent accidental liquid leakage.

Description

technical field [0001] The invention relates to a medical supply device, more specifically, to a medical liquid delivery device for clinical medicine. Background technique [0002] In clinical medical treatment, it is often necessary to inject some medicinal liquid into a human body or a medicine bottle through a clinical medical medicinal liquid delivery device. At present, this type of clinical medicine liquid delivery device generally releases all the medicine liquid at one time when in use, and generally adopts the method of rotating the knob cover on the valve when switching the clinical medicine liquid delivery device, or as an infusion tube The method of rolling and extruding the infusion tube on the cylindrical roller on the top is closed. The operation of this control method requires continuous toggle of the roller, which is relatively complicated. It is not timely enough to switch on and off the clinical medicine liquid delivery device. The infusion tube of the cl...
