Description

Ringer's fluid flow regulator

The present invention relates to a Ringer's fluid flow regulator, and more particularly, to a Ringer's fluid flow regulator that controls the flow rate linearly and the precision according to the section.

For example, the Ringer's fluid flow rate regulator is installed in the tube for supplying the Ringer's fluid, and adjusts the degree of pressurization of the tube by the operation of the wheel to regulate the supply flow of the Ringer's fluid. This Ringer's fluid flow regulator does not have a mechanism for indicating flow rate and degree of regulation.

Therefore, the user visually checks the degree of drop of Ringer's solution and adjusts the flow rate by manipulating the wheel. The accuracy of the flow rate regulation may vary depending on the user's skill.

As an example to solve this problem, the Ringer's fluid flow rate controller adopts a structure in which a flow rate is controlled by turning a wheel to control a flow path at a connection portion between the inflow and outflow sides of the Ringer's fluid.

That is, when the wheel is rotated, the position of the injection hole into which the flow rate is injected moves along the circumference. At this time, the size of the flow path is changed by changing the depth of the groove formed in the bottom member to meet the injection hole.

Since the groove is formed along the circumference of the bottom member, when the wheel is rotated, the size of the flow path formed cannot be linearly increased or decreased, and since the groove is formed in a fine width, high precision in manufacturing is required.

That is, it is impossible to linearly control the proportional flow rate according to the degree of wheel adjustment, and thus the precision of the flow rate adjustment is low.

It is an object of the present invention to provide a Ringer's fluid flow rate controller that linearly controls the flow rate and controls the precision according to the flow rate section.

The adjustment member may form an adjustment groove on a side facing the partition wall so as to form the passage in a portion facing the partition wall.

The adjustment groove may be formed to be inclined along a linear arrangement direction of the inlet, the partition and the outlet to form a variable depth.

The adjusting groove may form a variable distance spaced apart from the partition wall along a linear arrangement direction of the inlet port, the partition wall and the outlet port.

The body may form a guide formed in the reciprocating direction of the adjusting member at a height corresponding to the partition wall, and the adjusting member may be coupled to the guide to reciprocate.
