Embodiment Construction

[0070] The automatic cut-off sound-guiding drip funnel is connected with the external upper infusion tube and the external lower infusion tube to form a one-time automatic cut-off sound-guided venous infusion device. The design flow rate of the one-time automatic cut-off sound-guided venous infusion device is much greater than the actual flow of intravenous infusion Therefore, during the infusion process, there is always pressure in the disposable automatic cut-off acoustic guide venous infusion set, and the acoustic guide tympanum 1-2-4 of the automatic cut-off acoustic guide drip funnel is connected to the outside by the acoustic guide port 1-2-3 , so the pressure inside the sound guide tympanic chamber 1-2-4 is normal pressure, which is lower than the pressure of the medicine solution outside the upper tympanic membrane 1-2-5 and lower tympanic membrane 1-2-7, and the lower tympanic membrane will stretch upward during the infusion. Leave the liquid outlet conduit 1-3-2 below...

Abstract

The invention discloses an automatic cut-off sound-conduction dripping bucket, and the dripping bucket is designed based on gravity, pressure, sound-conduction and negative pressure theories, so that a disposal venous infusion apparatus dripping bucket has the automatic cut-off and sound-conduction function, through the automatic cut-off sound-conduction dripping bucket, when the solution in the infusion tube is reduced during venous transfusion, the lower infusion tube cannot result in air suction, reflux and blood return, at the same time, the dripping bucket can provide information to an external monitoring system, thus the dripping bucket has the characteristics of simple structure, complete function and strong manufacturability; in clinic application, the labor intensity of the medical worker can be effectively reduced by the dripping bucket, thereby greatly saving manpower resource and realizing standardized management in venous transfusion.

Description

technical field [0001] The invention relates to an automatic cut-off acoustic guide dripping funnel, in particular to an acoustic guiding drip funnel designed for a disposable venous infusion device, capable of transmitting sound information during the infusion process, and automatically shutting off when the liquid medicine is infused. Background technique [0002] The inventor has previously applied for many new types of infusion devices and new drip funnels, which mainly solve the technical problems of automatic cut-off of Chinese medicinal liquid in intravenous infusion and utilization of negative pressure conduction after cut-off. The present invention mainly solves the problem of sound in intravenous infusion. Questions are automatically cut off at the end of conduction and infusion. Contents of the invention [0003] The invention provides an automatic cut-off sound guide dripping funnel, especially an acoustic guiding drip funnel designed for a disposable intraveno...
