[0002] Existing ordinary infusion sets will enter the air after the liquid ends to cause blood backflow. High-end precision infusion sets also use filters to filter after the liquid enters the air. Patients still feel panic and anxiety when they see the air in the infusion tube and expel Fixed operation is required for air operation, and the filter is inverted, which is more cumbersome

specific Embodiment 1

[0023] The air-stop ball 5 in the air-stop Murphys dropper 2 adopts a hollow metal ball. When there is a liquid medicine in it, the buoyancy of the liquid medicine to the ball stop 5 is greater than that of the arc-shaped magnetic block 8 in the ball-stop traction mechanism 6 of the metal ball. Due to the traction force of the ball, the suspension of the stop balloon 5 on the liquid medicine does not affect the normal delivery of the medicine liquid. When the medicine liquid is dripped out, the stop balloon 5 comes to the bottom of the air-stop Murphys dropper 2 and blocks the infusion tube body 1. The mouth is connected to the bottom of the inner cavity of the air-stopping Murphys dropper 2, and the arc-shaped magnetic block 8 further attracts the air-stopping balloon 5 to ensure the stability of the air-stopping ballon 5 at the blocked mouth, preventing air from flowing backward into the body and causing The problem of blood backflow is stable.

specific Embodiment 2

[0025] The stop balloon 5 in the air-stop Murphys dropper 2 adopts solid nylon plastic balls. When there is a liquid medicine in it, the stop balloon 5 is suspended on the medicine liquid without affecting the normal delivery of the medicine liquid. At this time, the air-stopping balloon 5 comes to the bottom of the air-stopping Murphys dropper 2, and blocks the connection end between the mouth of the infusion tube body 1 and the bottom of the inner cavity of the gas-stopping Murphys dropper 2, preventing air from pouring back into the body and causing blood backflow. The problem is that the solid nylon plastic ball is used as the stop ball 5, its stability is average, and there is a problem of shaking and offsetting to block the hole.

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a novel Murphy's dropper. The novel Murphy's dropper comprises an infusion tube body, wherein an air-stopping Murphy's dropper, a drip speed controller and an infusion needle are sequentially connected to the infusion tube body in series; an air-stopping ball is arranged in the air-stopping Murphy's dropper; an air-stopping ball traction mechanism is arranged at an outlet in the lower end of an inner cavity of the air-stopping Murphy's dropper; and damping fluff is arranged in the drip speed controller. According to the novel Murphy's dropper, the air-stopping ball is placed in the air-stopping Murphy's dropper; when liquid medicine exists in the air-stopping Murphy's dropper, the air-stopping ball is suspended on the liquid medicine; when the liquid medicine drips completely, the air-stopping ball comes to the bottom of the air-stopping Murphy's dropper to block the connecting end of a tube opening of the infusion tube body and the bottom of the inner cavity of the air-stopping Murphy's dropper, so that the problem of blood flowback caused by flowback of air in the body is prevented; andmeanwhile, the damping fluff is arranged on the wall of a sliding groove in the drip speed controller, so that the sliding resistance of an idler wheel on the drip speed controller is improved, and the influence on the flow speed of the liquid medicine due to the fact that the self weight of the idler wheel drives a body of the idler wheel to slide downwards to press the infusion tube body is prevented.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a novel Murphys dropper. Background technique [0002] Existing ordinary infusion sets will enter the air after the liquid ends to cause blood backflow. High-end precision infusion sets also use filters to filter after the liquid enters the air. Patients still feel panic and anxiety when they see the air in the infusion tube and expel blood. When operating with gas, fixed operation is required, and the filter is inverted, which is more cumbersome. Contents of the invention [0003] In order to overcome the deficiencies of the existing infusion tubes that enter the air after the end of the infusion and cause blood backflow, the present invention provides a new type of Murphys dropper, in which a stop balloon is placed in the stop-air Murphys dropper. When the liquid is infused, the air-stop balloon is suspended on the liquid medicine without affecting the no...
