Drug concentration adjusting device for anesthesiology department

Abstract

The invention relates to a drug concentration adjusting device for an anesthesiology department. The drug concentration adjusting device comprises a support, a drug storage tank and a mixing tank, wherein the drug storage tank and the mixing tank are mounted on the support, and the lower portion of the drug storage tank is communicated with the upper portion of the mixing tank through a pressure valve. A piston and a push rod are arranged in the drug storage tank, the lower end of the push rod is connected with the piston, and the upper end of the push rod slidably goes through the drug storage tank. A floater and a guide rod are arranged in the mixing tank, the lower end of the guide rod is connected with the floater, and the upper end of the guide rod slidably goes through the mixing tank. The push rod is connected with the guide rod through a connecting rod and slidably hinged to the connecting rod, and the guide rod is hinged to the connecting rod. A straight channel is formed in the support, and the direction of the straight channel is consistent with the length direction of the connecting rod. A linearly sliding first slider is arranged on the connecting rod, a second slidersliding in the straight channel is arranged on the support, the first slider is rotatably connected with the second slider, and the rotating axis of the first slider and the second slider, the hinge axis of the push rod and the connecting rod and the hinge axis of the guide rod and the connecting rod are placed on the same plane. Screws are arranged on the second slider.

Description

technical field [0001] The invention relates to anesthesia medical supplies, in particular to a device for adjusting drug concentration in anesthesiology department. Background technique [0002] In the process of surgery or emergency medical treatment, anesthesia is usually used to relieve the patient's pain, and at the same time, it can also avoid the interruption of the operation or treatment process due to the patient's violent resistance, convulsions or conditioned reflexes in the middle; before anesthesia, it is necessary to first To prepare an appropriate proportion of anesthesia solution, the concentration of the solution directly affects the anesthesia effect, too high or too low concentration will easily lead to medical safety accidents; When preparing the liquid medicine, it should be operated in strict accordance with the regulations and requirements. However, since the existing anesthetic preparations are mostly prepared manually, it is necessary to use the scal...

Problems solved by technology

[0003] In view of the above situation, in order to make up for the technical deficiencies in the prior art, the present invention provides a device for adjusting drug concentration in anesthesia department to solve the problem of inaccurate concentration in the existing means of preparing anesthetic liquid and improve the concentration of anesthetic liquid. The efficiency of the preparation reduces the error rate of the preparation operation, so that the anesthesiologist can obtain the ideal concentration of the drug solution more conveniently and safely
