Switching assembly and self-switching-type infusion support

Abstract

The invention discloses a switching assembly and a self-switching-type infusion support. The switching assembly comprises a first fixed disc and a second fixed disc, the first fixed disc is fixedly connected with the second fixed disc through a connecting ring, and the connecting ring is sleeved with a switching wheel; the inner side of the switching wheel is provided with inner clamping teeth, the outer wall of the switching wheel is provided with opening and closing protrusions, the inner clamping teeth are in meshed transmission with a gear, the gear is fixedly assembled with one end of anoutput shaft, and the other end of the output shaft penetrates through the second fixed disc, and is then assembled with a motor; the first fixed disc is provided with avoidance grooves, clamping plates are installed in the avoidance grooves, the clamping plates are fixedly assembled with one ends of switch rods, the other ends of the switch rods penetrate through restoration holes and slide holesand then penetrate out of the first fixed disc, the penetrating-out ends are fixedly assembled with switch plates and force applying rings respectively, and the portions, between the restoration holes and the clamping plates, of the switch rods are sleeved with head springs; a cooperation ring is further fixed to the inner side of the first fixed disc, and fixed to a suspending shaft, and communication pipes are clamped through the cooperation of the cooperation ring and the clamping plates to cut off the communication state inside the communication pipes.

Description

technical field [0001] The invention relates to a transfusion stand, in particular to a switching assembly and a self-switching transfusion stand. Background technique [0002] The infusion stand is a very common device in medical machinery, and it is mainly used to support and raise the infusion bag to facilitate infusion. The current infusion stand mainly replaces the infusion bags that need infusion one by one, so as to perform bag-by-bag infusion. Obviously, this method requires manual observation of the amount of liquid medicine in the infusion bag, and medical personnel are required to replace the infusion bag after the liquid medicine is transfused, which is inefficient, time-consuming and laborious, and requires a high degree of manual participation. [0003] In some particularly busy medical environments, medical staff have no time to replace the infusion bag in time, such as when the number of patients in a major accident increases sharply, or when the first aid r...

AI Technical Summary

Problems solved by technology

At present, it is mainly used in emergency infusion, rescue room infusion and other environments. At this time, if the bag-by-bag infusion is still adopted, it will affect the allocation of medical personnel and the operation.

Moreover, if the replacement is not timely, it will lead to blood return, air input, etc., resulting in medical accidents.
