Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus used in a hospital when carrying out an infusion therapy to a person to be treated or to a patient which is capable of controlling the course of infusion, reading out the amount of the infusion directly using an efficient sensor, and informing the amount to the nurse station by carrier wave of inductive communication and can alleviate the burden of an operating person, that is, a doctor or a nurse or the like, to control and monitor the course of infusion while administering the infusion and to dispose the infusion when the infusion ends. <P>SOLUTION: An infusion medicine bag is provided with a mechanism 18 having an L/C sensor 22 or a semiconductor strain gauze for reading out the amount of infusion medicine solution 11, subjecting the amount to signal transformation and transmitting the data by infrared transmission. A receiver for receiving the infrared electric wave from the mechanism is installed in the ward. The inductive communication carrier wave from the installed receiver is transmitted not only to the main command board of the nurse station but also to the nurse via a portable tool. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a state monitoring system device that can easily detect the amount of drip liquid remaining.

  A / D converter that combines L (reactance) and C (capacitance) that automatically detects drip and digitally converts the pressure level using a semiconductor strain gauge and converts the data into infrared micro-transmitted radio waves equipped with a central processing unit Then send.

A feature is that the nurse call switch side receives the transmitted infrared radio wave, and the remaining amount detection data received by the infrared radio wave is arranged in the nurse center to notify the drip liquid remaining amount. The present invention relates to an infusion monitoring device.

  The main topic to be solved is that in the hospital, when instillation treatment is performed on a patient who is a patient, the doctor, nurse, etc. This is the point of infusion therapy.

Means for solving the problem

  The most important feature of the present invention is that a highly effective drip solution is directly read by a sensor and notified to the nurse station.

The invention's effect

  The drip monitoring system apparatus of the present invention has an advantage in that the amount of drip liquid is directly read by a sensor and directly transmitted to the nurse.

  The practitioner's instillation volume for the patient, who is the patient, and the nurse, the practitioner, achieved the purpose of ending the drip with the minimum number of parts without compromising the treatment accident at the end of the patient's drip.

  1, 2, 3, 4 are configuration diagrams of the first embodiment of the device of the present invention, and FIGS. 1 and 2 are a drip medicine bag detection sensor unit 3, a nurse call switch or red FIG. 4 is a diagram showing an apparatus provided for a nurse station.

The sensor 22 in FIG. 1 is transmitted by the infrared transmission unit via the LC circuit unit 20 and the reflected wave reception unit 13 through the signal conversions 14 and 15. Since the subject of the present invention is the microchip configuration of each block electronic component, description of the electronics and the mechanical system will be omitted.
The semiconductor strain gauge sensor of the sensor 30 in FIG. 2 is transmitted by the infrared transmission unit via the signal conversion circuit unit, the A / D conversion unit, and the central processing unit. Since the subject of the present invention is the microchip configuration of each electronic component of the block, description of the electronics and the mechanism system will be omitted.

Since the amount of infusion solution can be easily determined using an LC sensor or semiconductor strain gauge sensor attached to the infusion solution, it is easy for the practitioner, nurse, etc. to manage and monitor the progress of the infusion. Therefore, it can be applied to applications where direct viewing is indispensable.

Is a drip liquid bag detection L. It is block explanatory drawing of an apparatus provided with C sensor. These are the block diagrams of an apparatus provided with the drip liquid bag part detection semiconductor strain gauge sensor which concerns on this invention. These are the block diagrams of the apparatus with which the hospital room nurse call switch which concerns on this invention is equipped.
