Abstract
The invention relates to a mechanical device allowing patients to replace an infusion by manual control, and belongs to the field of medical instruments. A pulley supporting frame is installed on the left side of a base. A liquid medicine funnel with a supporting shaft is half embedded into the right side of the base. A sliding block track is installed in the middle of the base. A manual control rope hole is formed in the left side of the pulley supporting frame on the base. A liquid medicine replacement ratchet wheel is connected with the shaft of the liquid medicine funnel with the supporting shaft through a hinge and installed at the upper portion of the funnel. An infusion tube fixing disc is installed above the liquid medicine replacement ratchet wheel and connected with the upper portion of the supporting shaft of the funnel in a threaded mode. A main infusion tube is inserted into the funnel from a position below the base and reaches the bottom of the inner cavity of the funnel. The infusion tube is inserted into a through hole formed in the fixing disc from a position above the base and reaches the bottom surface of the fixing disc. One end of a reset spring is hooked to the bottom of the pulley supporting frame, and the other end of the reset spring is hooked to a sliding block. One end of a liquid medicine replacement pawl a and one end of a liquid medicine replacement pawl b are hinged to the two sides of the sliding block respectively.
