The present invention is a ringer for injecting the sap discharged from the ringer sap storage container into the blood vessels of the human body, equipped with a temperature detection means or a photo sensor on the tube through which the sap flows, the fluid is stopped or air in the sap The present invention relates to a ringer sap administration condition monitoring apparatus and method for automatically detecting a mixed state in real time and informing a guardian or a nurse when such a phenomenon is detected or automatically blocking the supply of the sap.

Ringer nourishes or administers certain ingredients to the body and is essential for patients.

In some cases, however, the sap does not flow into the human body and stops. This phenomenon occurs when the sap reservoir is lower than the human body, and when the blood flows back due to a difference in pressure, the blood coagulates. If this condition is left as it is, the fluid continues to flow into the tube, increasing the internal pressure and pushing solidified blood, that is, the generated blood clot, into the blood vessel. It moves and adheres to capillaries and the like, which interferes with the normal flow of blood, which may cause stroke or heart attack, as well as problems such as bursting of blood vessels by pressure.

In addition, in case of mistake or missed replacement time of the sap storage container, if air bubbles flow into the sap, bubbles flow along the sap into the tube, and when this enters the blood vessels of the human body, air enters into the blood vessels and becomes dangerous. Or caregivers and nurses often had the inconvenience of monitoring the patient for normal administration of fluid and exhaustion of fluid.

The present invention is to solve such a problem,

The first objective is to automatically check whether the fluid flows normally in the tube tube through which the fluid flows, and to notify the guardian or nurse of the abnormal condition.

Another object of the present invention is to reduce the risk of the patient and reduce the workload of the nurse by knowing from a remote location when the fluid does not flow normally.

Another object of the present invention is to prevent a medical accident that may occur by blocking the flow of the fluid quickly when abnormal flow of fluid is detected.

The present invention for achieving the above object

In the Ringer's fluid syringe comprising a fluid storage container, a tube and a needle,

A monitor is provided at a predetermined position of the tube, wherein the monitor is heated to a predetermined temperature by being adjacent to or in contact with the tube, a sensor for measuring a temperature change of the tube around the heating unit, and detected by the temperature sensor. And a notification unit for displaying the abnormal signal transmitted from the control unit.

The heating unit is preferably an electric heating heater for heating in an electrical manner, the heating temperature is preferably 40 ℃ to 45 ℃. In general, the tube is manufactured so as not to be deformed, such as shrinkage or expansion even at a high temperature of about 70 ° C, so the width of the rising temperature can be set to the limit temperature of the tube, but problems such as boiling of sap may occur. There is a risk of changing the properties of the sap itself, and on the contrary, if the temperature is lowered, since it is difficult to detect a change in temperature, it is preferable to heat to a temperature of about 40 ℃ to 45 ℃.

When heated in this way, the heat is transferred to the tube, and the temperature measuring part opposite to the heating part senses a uniformly lowered temperature through the tube and the sap. As long as the internal fluid has a constant flow, the detected temperature is maintained at a constant level, but when the flow of fluid stops due to coagulation of blood, the temperature rises, and when the temperature detected by the sensor increases, the controller You will be alerted.

The present invention may further include an abnormality detecting sensor for detecting whether the sap is normally administered or the state of the sap, and the abnormality detecting sensor may be a photosensor. When the abnormality detection sensor is a photosensor, it is preferably configured to be spaced apart from the heating unit, and is composed of a light emitting unit and a light receiving unit to determine the refraction of the light inside. Therefore, when the sap is exhausted and no more sap flows through the tube, or when air is introduced into the sap, or other reasons, the photosensor may indicate whether the sap is exhausted or whether the sap is abnormal.

The present invention may further include an infusion blocking unit for blocking the infusion supply in accordance with the signal of the control unit.

The controller may transmit the abnormal signal to a monitoring apparatus provided in a nurse room or the like through a power line modem or may issue an alarm through a mounted display unit. When the abnormal signal is transmitted to the nurse room through a means such as a power line modem, the power line modem of the nurse room receiving the data transmits the abnormal signal to a connected monitoring device such as a computer. The abnormal signal may be transmitted to the computer and interpreted by a software method.

The alarm device may be a remote computer or an alarm device such as a warning light or a buzzer provided in the device.

The Ringer's fluid administration monitoring device may have an opening and closing door to minimize the temperature change from the outside. When there is an opening and closing door as shown in Figure 3, since it is hardly affected by the temperature change from the outside, it is possible to accurately determine the state of maintaining or rising temperature.
