A mechanical device for patient manual replacement of transfusion

Abstract

The invention relates to a mechanical device for manually changing infusion fluid by a patient, which belongs to the field of medical instruments. The pulley support frame is installed on the left side of the base, the medicine solution funnel with the support shaft is half-embedded in the right side of the base, the slider track is installed in the middle of the base, the left side of the pulley support frame on the base is provided with a manual rope hole, and the liquid change ratchet It is connected with the shaft hinge of the funnel with support shaft and installed on the upper part of the funnel. The infusion tube fixing plate is installed on the top of the liquid change ratchet and is threaded with the upper part of the support shaft of the funnel. The main infusion tube is inserted from the bottom of the base to the bottom of the inner cavity. Insert the through hole opened on the fixed plate from above to the bottom of the fixed plate. One end of the return spring is hooked to the bottom of the pulley bracket, and the other end is hooked to the slider. The two ends of the contraction spring are hooked to the inside of the middle part of the fluid changing pawls a and b, and the other ends of the fluid changing pawls a and b are in reliable contact with the fluid changing ratchets. The invention can control the infusion sequence stably and accurately, and can control the fluid change by itself through the hand control rope, so as to reduce the workload of medical personnel.

Description

technical field [0001] The invention relates to a mechanical device for manually changing infusion fluid by a patient, which belongs to the field of medical instruments. Background technique [0002] In the static point room or ward of the hospital, there are usually many patients undergoing infusion at the same time. After a bag of liquid medicine is infused, most of them need to change the bottle or bag of liquid, and the work of changing the medicine is usually done by one or a few nurses. , due to too many patients, it is often the case that several patients in different wards change their dressings at the same time. The medical staff need to carry the liquid medicine between each ward, and the workload is heavy. During this process, the patients need to turn off the infusion device Waiting to change the medicine will inevitably affect the impatience of some patients. How to allow patients to change the medicine solution by themselves through simple operations, reduce th...
