Flow-rate regulator, flow-rate-regulating set, and method for regulating the flow-rate of intravenous fluid

Abstract

The prevent invention relates to a flow rate regulator, to a flow-rate-regulating set, to a method for regulating the flow-rate of intravenous fluid, in which a reference point is defined in the manipulating range of a manipulating part for regulating a flow rate of the intravenous fluid so as to match a manipulation point of the manipulating part with a flow rate measured at a reference point with respect to a prescribed flow rate to be injected, thereby quickly and precisely regulating the prescribed flow rate.

Description

technical field [0001] The invention relates to a transfusion flow regulator, a transfusion flow regulating device and a transfusion flow regulating method which can quickly and accurately adjust the transfusion flow to the prescribed flow. Background technique [0002] Such as figure 1 As shown, the intravenous infusion device (IV) for directly injecting the injection into the vein consists of an infusion bottle 1 containing the injection, and a bottle insertion needle 11 inserted into the airtight cover of the infusion bottle and capable of dripping the infusion, fixed on the The lower end of the insertion needle 11 can make the injection solution drip in the form of droplets (12a, drop, unit: gtt) into the drip chamber (Drip Chamber) 12, insert the infusion needle 14 into the vein, and connect the drip chamber 12 and the infusion The needle 14, the connecting tube 13 as the infusion channel, and the infusion flow regulator 15 which is arranged in the middle of the infusi...

Problems solved by technology

[0010] Korean No. 10-0706954 patent "Infusion Infusion Speed ​​Measuring Device" and Korean No. 10-0872089 Patent "Infusion Infusion Auxiliary Device" invented by the inventor, although easy to carry, and can quickly and easily adjust the infusion flow , however, it is necessary to repeatedly operate the operation part 15a of the infusion flow regulator 15 until the dripping cycle of the liquid drops coincides with the sound cycle

As mentioned above, the existing infusion flow regulators all have disadvantages such as troublesome operation and need to go through several operations to achieve accurate flow.
