Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to an automatic shut-off device for Ringer's solution. More particularly, the present invention relates to an automatic shut-off device for Ringer's solution, When the field effect transistor is turned on, power is supplied to the solenoid coil, the solenoid head is released from the state where the spring force of the spring is released, and the switch contact is turned off to cut off the power supply. The present invention relates to an automatic cut-off device for Ringer's solution that can accurately perform operation while consuming a low current by using a simple configuration and safely use liquid injection.

In general, drip injections are injections for the purpose of injecting a large amount of drug solution. Usually, a rubber tube or a vinyl tube is connected to an irruri gaitol having a capacity of 500 to 1,000 cc, and the needle is pierced by a needle And a glass tube for increasing or decreasing the rate at which the chemical liquid is dropped is located at the middle of the tube. A glass tube is inserted between the tube and the needle for eliminating the air if the liquid is mixed with the glass tube. Is provided with an exhaust passage.

Usually the main vein is used, but injected into the vein of the internal part of the upper ankle joint. The needle is fixed to the skin with a band-aid at the root of the needle or at the site of the glass tube to prevent it from falling out.

The speed of the drop is generally limited to 200-300 ml per hour, especially in the case of elderly or infants.

In such a case, it takes a relatively long time to perform the dots injections, so careful care and consideration of the caregiver are required to check the supply amount and the supply state of the chemical liquid from time to time and observe the remaining amount.

The conventional feeder set is constituted by a dotted portion to which the chemical liquid is to be dispensed, a regulating portion provided at the central portion of the hose capable of being bent freely, and a needle needle connected to the other end of the dotted portion.

That is, when the chemical solution is supplied by inserting the insertion port of the drip part integrally provided with the air inlet and the chemical solution outlet into the ringer bottle or color, the chemical solution supplied to the drip part is supplied through the hose to the injection needle and supplied to the blood vessel, The adjusting portion provided on the outer circumferential surface of the hose through which the hose is passed serves to adjust the supply amount.

However, if the conventional supply set fails to recognize the completion of the supply of the chemical liquid due to carelessness during the supply of the chemical liquid, air may be introduced into the human body and the supply region may be swollen to a great extent, There was a very dangerous problem that I could do.

Thus, a utility model registration No. 20-0219718 (an air inflow cut-off device for a medical fluid feeder) of Jan. 30, 2001 has been proposed,

This is because a flexible hose capable of bending freely is connected to the lower end of a drip member having a mouth ring or a color engaging member, and the hose is provided with an adjusting member for adjusting the supply amount and a needle for injecting into the body, In the known liquid supply device,

And a valve that is circular in cross section on the inside of the drip member and operated by the lifting force and self weight of the liquid chemical to completely seal the pipeline as the case may be so that the chemical liquid passing through the pipeline of the drip member is depleted The valve that was floated by the buoyancy loses the flotation power and at the same time the self weight is applied and it drops to the lower part of the pipe having the inside diameter smaller than the diameter of the valve to close the pipeline and the inlet of the hose is blocked, The risk of accident was prevented.

However, when the chemical solution is depleted, the valve closes the channel due to its own weight due to the air inflow and outflow device of the conventional medical fluid feeder. However, when the valve is not a correct sphere or foreign matter is introduced, There is a problem that it can not be blocked.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a photocoupler provided in a sap tube for supplying sap, The field effect transistor is turned on and power is supplied to the solenoid coil, the solenoid head is released from the state in which the head of the solenoid receives the elastic force of the spring, while the switch contact is turned off to cut off the power supply, The present invention has been made to solve the above problems, and it is an object of the present invention to provide an automatic cut-off device for Ringer's solution that can accurately perform operation while consuming a low current by using a simple structure and safely use liquid injection.

To achieve the above object, according to the present invention, there is provided an automatic cut-

(Not shown) for injecting liquid into a human body via a regulating member (not shown) from a ringgear supply container (not shown in the figure) 2, if the air is not contained in the liquid, the sensitivity of the light receiving portion 2a is not changed by the light of the light emitting portion 2a due to the lens effect of the liquid, The light of the light emitting portion 2a is scattered by the air of the light receiving portion 2b to detect whether the sensitivity of the light receiving portion 2b is lowered to increase the equivalent resistance value,

The field effect transistor 3 is turned on to supply power to the solenoid coil 4 only when the air in the liquid pipe 1 is detected and the equivalent resistance value of the photocoupler 2 is raised,

As the power is supplied to the solenoid coil 4, the head 6 of the solenoid 5 protruding forward can be pulled out and pulled quickly by the restoring force of the coil spring 10,

As the head 6 of the solenoid 5 is quickly pulled out, one of the tongs 7, which is released from the state in which one of the tongs 7 is opened and receives the elasticity of the spring 8 installed on the other side, The switch contact 9 in the ON state is turned off to cut off the supply of power, and at the same time, the open tongue 7 catches the liquid tube 1 and blocks the supply of the liquid.

When the air in the liquid pipe 1 is detected and the equivalent resistance value of the photocoupler 2 is lowered, the power is not supplied to the solenoid coil 4 while the field effect transistor 3 is kept off do.

Since the head 6 of the solenoid 5 protruding forward as the power is not supplied to the solenoid coil 4 keeps a state in which one side of the clamp 7 is opened, The power supply is normally supplied through the contact 9 and the clamp 7 can not hold the fluid pipe 1, so that the fluid is normally supplied.

However, when there is no liquid or other reason, when air flows through the liquid pipe 1, the light of the light emitting portion 2a is scattered by the air of the liquid pipe 1 and the sensitivity of the light sensed by the light receiving portion 2b The equivalent resistance value is increased.

The field effect transistor 3 is turned on and power is supplied to the solenoid coil 4 only when the air in the liquid pipe 1 is detected and the equivalent resistance value of the photocoupler 2 is raised.
