Description

[0001] DRUG INJECTION CONTROLLER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drug solution amount regulator for regulating the amount of a drug solution such as a Ringer's solution and a special injection drug injected into a patient, and a means for additionally administering a drug solution or a filter for filtering foreign matters, And it is possible to implement various functions by hanging only one chemical liquid quantity adjusting device without using various equipment on the ringer line.

Patients admitted to a hospital are usually administered a liquid medicine such as a nutrient called glucose, a rinse liquid such as glucose, and a special injectable solution to the ringer device.

Currently, a ringer device commonly used in medical institutions is a gravitational method in which a pack or bottle containing a fluid is lifted higher than a scanning position to secure the potential energy and a chemical solution is injected into the patient using the pressure difference. The rate of injection of the chemical solution is controlled by the amount of the chemical solution supplied through the chemical solution amount adjuster mounted on the ringer bar (the ringer bottle or the hose connected to the pack) which can be easily seen at a place such as a hospital.

The most general structure of such a chemical feed amount regulator is mainly a method of controlling the flow rate by reducing or increasing the cross-sectional area of the hose which is a flow path through which the chemical liquid is injected by moving the pressure roller moving in the inclined groove.

However, the method of pressing the hose by moving the pressure roller is advantageous in that the price is low, but the pressure roller that presses the hose by the restoring force of the hose made of soft synthetic resin or rubber is arbitrarily moved, It is very dangerous because it happens often, and it is inconvenient to use because it requires careful observation.

In addition, since the user adjusts the rate at which the chemical liquid is injected by adjusting the pressure roller while watching the clock when setting the rate at which the chemical liquid is injected, there is a problem that the error range of the flow rate is too large according to the skill of the user.

Therefore, in recent years, there have been proposed various types of chemical liquid quantity regulators which can easily adjust the flow rate and maintain the dosage constant.

However, most of the proposed chemical feed regulator does not have the error range of the flow rate. However, since the structure is too complicated, the product price is expensive and not practical. Therefore, the most cheap and simple type of hose pressurization Of the flow rate regulator is used.

On the other hand, the ringer device may be additionally equipped with various kinds of instruments as auxiliary means for administering the drug solution as well as drugs such as nutrients and special injections.

For example, auxiliary injecting valves for additionally administering a special injecting agent to a patient during administration of the drug solution, auxiliary devices such as a filter for removing foreign substances contained in the drug solution, and the like may be mounted.

However, it is very troublesome to install several instruments on one ringer line, and when each of the instruments is hanged on the ringer line, the aesthetics are not good and risk factors can be accompanied.

In other words, if the patient is to move away from the bed to move the bed to see the toilet, to receive the physical therapy, or to consult the patient for medical treatment, the patient must move with the ringer attached. Because it is often caught by clothes or other items, it must be used with extreme caution, it is very cumbersome to use, and in some cases it may happen that a ringer cord is caught.

In addition, each time a plurality of mechanisms are connected, each of the mechanisms is provided with a connection portion so that the hoses are connected to each other. Therefore, when the connection portion is not properly connected, In the injection, as the number of the connection portions increases, the connection portion becomes a leak point, so there is a problem that the pressure leaks finely, and it is more difficult to finely control the flow amount.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a system for controlling the flow rate of a chemical solution to be administered to a patient, So that various functions can be implemented.

In addition, it is possible to control the dosage of the chemical solution by operating the flow rate control knob, and at the same time, to switch the function of opening the additional chemical solution inlet, thereby simplifying the structure and manufacturing the chemical solution at low cost.

According to an aspect of the present invention, there is provided a regulator including a regulator body, an inlet and an outlet provided in the regulator body to allow a chemical liquid to flow in and out, And a charging unit provided in the regulator body so as to inject the additional medicament, wherein the regulator main body has an inner space communicating with the inlet, the discharge unit and the charging unit, And a cylinder which is inserted into the space and operated by the knob. The cylinder is provided with a flow path groove for selectively opening the flow path of the inlet portion or the inlet portion, thereby simultaneously shutting off the flow path of the inlet portion and the inlet portion, So that the discharge portion and the flow path can be operated to communicate with each other.

According to the multifunctional medicament supply amount regulator of the present invention, it is possible to accommodate various functions with a single medicament supply amount regulator without having to mount a plurality of auxiliary mechanisms on each of the ringer lines, thereby enabling a medical person, such as a nurse, can do.

In addition, since the leakage point, which is a portion to which the hose is connected, is minimized and the flow rate is directly controlled, the cross-sectional area of the flow path is not arbitrarily changed, and a constant amount of injection can be performed without any change in cross-sectional area or irregular flow rate due to pressure difference .

In addition, since there is no need to hang various auxiliary devices on the ringer line, it is possible to use it with ease when the patient is moving or moving, and can reduce the risk of hanging hanger by hooking ringer line.

In addition, since operation such as adjusting the dose of the chemical solution or opening the additional chemical solution inlet is performed by operating the flow rate adjusting knob, it is easy to use and can be manufactured at a low cost by realizing the function switching with a simple structure, .

The structure of the flow rate regulator 400 includes a cylinder 420 inserted into the inner space 120 of the regulator main body 100 and a flow path groove 430 formed in the cylinder 420, And a knob 440 which is exposed to the outside of the regulator main body 100 in order to perform the operation.

The structure in which the cylinder 420 is assembled to the inner space 120 is such that a sealing member 422 is installed on the outer circumference of the cylinder 420 and the sealing member 422 is brought into close contact with the inner circumference of the inner space 120 The cylinder 420 can be rotatably operated using the knob 440 in a state where the cylinder is assembled by inserting it into the inner space. The structure in which the cylinder 420 is assembled in the inner space 120 can be achieved by using a fixing member Or it may be assembled in a forced fitting manner with a step, or may be rotatably operated in a state where it is not arbitrarily separated, and various known assembling structures may be applied.

At this time, the inner space 120 provided in the regulator main body 100 is hollow and cylindrically shaped so that the cylinder 420 of the flow rate regulator 400 is closely attached to the inner circumference of the inner space When the flow path groove 430 is formed along the outer periphery of the cylinder 420, the flow rate of the knob 440 can be adjusted by rotating the knob 440.

Here, the channel groove 430 is formed such that the end face of the channel groove 430 is inclined along the outer periphery of the cylindrical cylinder 420, so that when the rotation operation is performed by the knob 440 exposed to the outside of the regulator main body, It is possible to block, enlarge or reduce the cross section of the display screen.

When the cylinder 420 is rotated by the rotation of the knob 440, the flow grooves 430 may be formed in the inlet portion 430, It is possible to shut off both the inlet 200 and the inlet 500 or to selectively open only the outlet of the inlet 200 or the inlet 500.

For example, as shown in FIG. 3, the inlet portion 200 and the inlet portion 500 are provided so as to be orthogonally positioned in the clockwise direction, and the flow channel groove 430 formed in the cylinder 420 is inserted into the inlet portion The grooves may be formed in a counterclockwise direction within a range that can block both the input unit 200 and the input unit 500 and the rest may be formed as the blocking unit 422 to block both the input unit 200 and the input unit 500 Or only the flow path of the inlet portion 200 or the inlet portion 500 can be selectively opened.

5, the cut-off section 422 of the cylinder 420 operates the knob 440 to move the inlet 202 and the inlet 502 formed in the inlet 200 and the inlet 500, It is possible to block the injection of the chemical liquid.

The knob 440 is operated so that the flow path groove 430 of the cylinder 420 is communicated with the inlet port 202 of the inlet portion 200 and the outlet port 302 of the outlet portion 300 as shown in FIG. It is possible to administer the drug solution suspended from the lower ringer device to the patient.

7, the knob 440 is operated so that the flow channel groove 430 of the cylinder 420 is communicated with the inlet port 502 of the charging unit 500 and the discharge port 302 of the discharging unit 300 The drug solution such as a special injection can be administered to the patient through the injection unit 500.

The flow rate regulator 400 may further include a stopper 460 for limiting a rotational operation range of the cylinder 420 corresponding to the regulator main body.

The stopper 460 is for regulating the angle at which the flow path groove 430 communicates with the cylinder 420 by limiting the operation range of the cylinder 420. The stopper 460 protrudes from the stopper 460, A pivotally-formed pivotal groove 160 may be provided to accommodate the protruded stopper 460 and limit the pivotal range of the stopper.

In addition, the display unit 480 may be provided to visually check the flow rate adjustment amount from the outside and confirm the flow path switching function to the inflow unit 200 or the input unit 500. [

The display unit 480 may include a display unit 480 on the knob 440 corresponding to the range of movement of the stopper 460. The display unit 480 may include a control scale 482 for checking the cut- And a conversion scale 484 for confirming whether or not it is possible.

Meanwhile, the regulator main body 100 may include a vent hole 140 for applying a natural atmospheric pressure to the regulator main body so as to maintain a constant pressure of the flow path through which the chemical liquid is injected.

As shown in FIGS. 2 and 4, the air vent 140 may be equipped with an air filter 142 for filtering foreign substances contained in the air supplied from the outside. In this case, Various types of air filters, such as synthetic resin, rubber, or metal, may be installed.

The discharge unit 300 is provided with a chemical filter 600 to remove foreign substances contained in a chemical solution such as Ringer's solution or the like injected into the inlet 500, .

In particular, the chemical solution such as a special injection supplied to the injection unit 500 is often injected with a chemical solution stored in an ampule or the like. When the chemical solution is taken out by a syringe, a small amount of foreign substance such as an ampule glass piece or rubber is contained in the chemical solution When the drug solution is injected into the injection unit 500 for administering the drug solution to the patient, the drug solution can be administered to the patient in a state where the foreign substance is filtered by the drug solution filter 600.

The cross-sectional area of the chemical filter 600 contacting the filter and the chemical solution may be formed to be wider than the cross-sectional area of the discharge port, so that the chemical solution filter 600 may be provided in a shape of a circular pipe in the form of a closed rear so that pressure dispersion occurs during discharge of the chemical solution.

The closed end of the filter may be formed in a circular pipe shape and the other end may be clogged so that when the open portion is mounted to the lower side of the discharge portion 300, So that the foreign substance remaining in the chemical solution can be passed when the chemical solution supplied to the inlet 200 or the inlet 500 is discharged without being clogged by the discharge unit 300 via the flow path.

At this time, when the chemical filter 600 has a long length and extends to the upper side, the cross-sectional area of the filter through which the chemical liquid is absorbed can be further increased, thereby allowing the chemical liquid to be smoothly discharged while further increasing the pressure applied during discharge of the chemical liquid. The length of the filter 600 can be extended within a range that does not directly contact the cylinder 420 of the flow rate regulator 400.

3, the discharging unit 300 includes a housing 320 detachable from the regulator main body 100, and a mounting portion 340 is formed on the discharging side of the housing 320 So that when one end of the filter is opened and the other end of the filter is coupled, the one end of the filter is coupled to the step 341 of the mounting part so as to face the discharge part 300 side, The housing and the spacing space 1 are provided to increase the cross-sectional area of the chemical solution filter 600 so that the amount of the filter can be increased, and the chemical solution filter 600 can be easily replaced and used according to the use period.
