Description

A device for regulating a ringer volume}

The present invention relates to a Ringer's fluid infusion regulator to control the amount of Ringer's fluid is injected into the blood vessel of the patient. More specifically, the flow rate of Ringer's fluid can be finely adjusted according to the patient's condition, and the amount of Ringer's fluid is generated due to the low or excessive amount of Ringer's fluid by maintaining the constant flow. The purpose is to prevent safety accidents in advance.

In general, nutrients or specially prepared glucose, injections, etc. are contained in Ringer's disease and injected into the patient's blood vessels to help the metabolism of patients with reduced digestive function and restore their vitality.

Conventionally, in order to inject Ringer's fluid into a patient's blood vessel, the patient's necessary amount is controlled by using a Ringer's fluid injector, and the constitution (see FIG. 2) is a rubber material at the inlet of the bottle. Ringer bottle 100 sealed with a stopper of 100, one end is composed of a needle portion 102 to be in close contact with the inside of the ringer bottle, the needle 103 is coupled to the other end, the soft transparent ringer hose (101) And it is composed of an injection amount regulator (not shown) to adjust the amount of fluid by reducing and expanding the cross-sectional area of the ringer hose received inward by the pressure roller flowing in the inclined groove installed on the ringer hose As already noted.

The Ringer's fluid infusion controller has a structure such as this, and the nurse inserts a syringe into the patient's blood vessel and adjusts the infusion regulator to adjust the amount of fluid flowing through the Ringer's hose to supply the patient with the required amount.

However, the ringer hose is made of soft synthetic resin or rubber material, and the pressure roller that pressurizes the ringer hose is gradually changed from its original press position by the ringer hose's own restoring force, and the ringer's fluid is excessively administered as the cross-sectional area of the ringer's hose is expanded. It is pointed out that a problem that may cause an emergency situation to the patient occurs. Therefore, very careful observation of the guardian or nurse is required. In particular, in the case of continuously administering Ringer's fluid to the patient, it was not easy to control the flow rate of Ringer's fluid again as before.

In recent years, an injector (Injector) that can finely control the flow amount of the sap is widely used, but the price is so expensive that it is difficult to store and manage because it must be installed and managed separately from the Ringer's fluid injection controller.

In addition, the malfunction and failure rate of the device is frequently pointed out that a problem that may cause a risk to the patient when the fluid is not administered to the patient due to the failure or excessively administered fluid.

The present invention has been devised to solve this problem, and it is possible to finely control the flow amount of Ringer's solution by simple valve operation without external pressure action such as pressure increasing means for expanding or reducing the cross-sectional area of the Ringer's hose as in the related art. By ensuring that the amount of Ringer's fluid is kept constant at all times, it is possible to prevent safety accidents caused by low or excessive amount of Ringer's fluid flow.

The present invention consists of a housing in which the inlet hole and the outlet hole are vertically communicated with the outer wall, and a valve body inserted into the rotating body, and closely connected to the inside at the point where the inlet hole and the outlet hole of the housing form the same line. A second flow path groove is formed on the outer circumference of one valve body to easily control the flow and amount of Ringer's fluid by selectively allowing the second flow path to communicate with or block the inlet and outlet holes by rotating the valve body. To help. In addition, the depth of the second flow path groove through which the Ringer's fluid flows is gradually contacted with the outer circumferential surface at a point along the outer circumference of the valve body so that the flow amount of the Ringer's fluid can be finely adjusted according to the rotation of the valve body. do.

According to the present invention, a cylindrical housing 12 having an inlet hole 12 and an outlet hole 12 ′ communicating with the inner side in a tangential direction close to the outer wall and having a rotating shaft hole 13 formed at the front center thereof, coincides with the inner circumferential surface thereof. It is tightly fitted with a diameter to one end is extended to the outside of the housing, it is composed of a valve body (16) rotatable about the rotating shaft hole (13), which is built up, supported by the rotating shaft hole (13), A first flow path 20 is formed on the outer surface of the valve body to communicate with the inlet hole and the outlet hole, while a groove having a predetermined width and depth at an upper point close to the first flow path is formed with a long outer peripheral distance. A second flow path groove 22 is formed in which the depth of the groove gradually contacts the outer circumferential surface until the lower point of the flow path 20 is approached.

The present invention, in addition to the above configuration, is placed in accordance with the insertion groove 14 wider than the width of the second channel groove around the inner peripheral surface of the housing 11 which is in contact with the second channel groove 22 and the first channel 20 The second flow path groove 22 is sealed by a leakage preventing packing 24 having a hole 24 'penetrated into the inner and outer surfaces on a line coinciding with the inner wall.

Therefore, since the inner circumferential surface of the leakage preventing packing 24 having a cross-sectional area wider than the width of the groove is closely connected to the upper surface along the outer circumference of the second flow path 22, leakage or external air is introduced during the flow of Ringer's fluid. This will provide a more stable passageway.

In addition, the locking projection 15 is integrally formed on the inner end of the housing 11 on the horizontal axis, while the locking protrusion 23 is integrally formed on the rear surface of the valve body 16 positioned at an acute angle based on this. .

Accordingly, the ring body fluid flows by rotating the valve body 16 counterclockwise by the adjustment mechanism 18 extending in front of the housing 11 so that the second flow path groove 22 communicates with the inlet hole and the outlet hole. When adjusting the amount, the locking projection 23 formed on the rear of the valve body 16 is rotated in the same direction to be in contact with the bottom surface of the locking projection 15 formed on the inner side of the housing 11 on the horizontal axis of the valve body 16. Rotation of is made to be controlled.

In addition, as another embodiment of the present invention, the second channel groove 22 is a constant depth and the width will be desirable to be made narrower gradually toward the longer the outer peripheral distance.

Hereinafter, a description will be given with reference to FIGS. 1 to 4 attached to the assembly operation of the Ringer's fluid injection amount regulator according to the present invention and the resulting effects thereof, and for reference, the housing 11 may be divided in half to install the valve body 16. When each pair is molded and manufactured in pairs, the joints are made to be joined together by ultrasonic bonding.

First, the leakage preventing packing 24 is positioned so that the second flow path groove 22 formed along the outer circumferential surface of the valve body 16 is sealed, and the hole 24 ′ is formed through the inner and outer surfaces of the leakage preventing packing 24. The first channel 20 is located on the same outer circumference as the second channel groove 22 so as to be in communication with each other. Thereafter, an adhesive is applied to the outer circumferential surface of the leakage preventing packing 24, and then the valve body 16 is installed so that the leakage preventing packing coincides with the insertion groove 14 formed in the housing 11. Is adhered to, and fixed to, the insertion groove 14 of the housing 11 by an adhesive applied to its outer surface, so that the hole 24 'formed through the inner and outer surfaces of the leakage preventing packing is inserted into the housing 12 ) Is always in communication with the outlet hole 12 '.

Subsequently, assembling is completed by matching the upper and lower housings 11, which are divided in half, and jointing the joints with ultrasonic waves, and the assembled Ringer's fluid injection controller 10 is installed on the Ringer's hose 101. Ringer hose 101 is coupled to the inlet hole 12 and the outlet hole 12 'respectively configured in the upper and lower sides by interference fitting.

Figure 4 (a) (b) (c) (d) is a sequential diagram showing the operating state and the operation process when the valve body 16 is rotated counterclockwise by the adjustment mechanism 18 (a) As shown in), the first flow path 20 formed on the outer surface of the valve body 16 by the adjustment mechanism 18 so that the upper inlet hole 12 and the lower outlet hole 12 'of the housing 11 communicates with each other. Match vertically. In this way, the Ringer's fluid flowing along the Ringer's hose 101 from the Ringer bottle 100 mounted on the upper portion in the vertically communicated state flows into the inlet hole 12 of the housing 11 to form the first valve body 16. One passage 20 passes through the outlet hole 12 ′ and reaches the injection needle 103 so that air is discharged onto the ringer hose.

Thereafter, the needle body 103 is inserted into the blood vessel of the patient so that the valve body 16 is rotated counterclockwise by the adjusting mechanism 18 so that a predetermined amount of Ringer's fluid filled in the ringer hose 101 is injected. Accordingly, the first flow path 20 is temporarily blocked from the inlet hole 12 of the housing 11 to the flow of the Ringer's fluid, and at the same time, the second flow path groove formed on the same outer circumference near the first flow path 20 ( 22) When the inner bottom surface of the inlet hole 12 of the housing is also moved counterclockwise, as shown in FIG. 3C, the Ringer's fluid blocked in the inlet hole is formed in the volume of the second channel groove 22. A corresponding amount is introduced and flows to the needle through the outlet hole 12 ′ communicated along the second flow path groove 22.

At this time, the outer circumferential upper surface of the second channel groove 22 is tightly sealed by the leakage preventing packing 24 which is intimately closed, so that no external air flows into the second channel groove or the Ringer's fluid is leaked.

4D illustrates a state in which the second flow path 22 communicates with the inlet hole 12 and the outlet hole 12 'so that the Ringer's fluid can achieve the maximum flow rate, and the valve body 16 is rearward. The engaging projection 23 formed in the contact with the engaging projection 15 of the housing 11 is in a state in which further rotation is controlled.

Therefore, the present invention adjusts the flow amount of Ringer's sap in accordance with the volume of the selected point communicating with the inlet hole 12 and the outlet hole 12 'of the housing 11 within the outer circumferential length of the second flow path groove 22 is formed. In addition, since the valve body 16 is rotated in such a state that its outer surface is closely intimately connected to the inner circumferential surface of the leak-proof packing 24, the position of the valve body 16 is not easily changed unless the external pressure is applied. It can be kept constant, allowing more stable administration of Ringer's fluid to patients.

The present invention has a structure in which the second flow path is communicated or blocked at the inlet and outlet holes selectively by the rotational operation of the valve body, so that the flow of the Ringer's solution can be finely controlled by a simple operation as well as the controlled Ringer's solution. Since the amount of fluoride can be maintained at a constant flow rate, it is possible to prevent safety accidents caused by a small flow rate or excessive administration of Ringer's solution.
