Description

AN INFUSION TRACKING AND CONTROL SYSTEM
Technical Field
The invention is related to an infusion tracking and control system which allows measuring or calculating quantitative values of the fluids such as serum, blood etc. administered to the patients.
The invention is particularly related to an infusion tracking and control system which enables tracking, storing and intervening when necessary the relevant data with the fluid by means of creating audial or visual warning within it and within the central control system in terms of the relevant data of the measured or calculated fluid.
State of the Art
The infusion is the intravenous administration of the drug or fluids to a patient through a tubing system. Today the infusion sets operate with drop adjusting sets. In the typical infusion sets, the distribution speed of the fluid flow can be adjusted in a manual manner by controlling the fluid drops falling into the dropping chamber of the user in a visual manner and thus by adjusting the clamp, is applied to the patient by various types of pumps with an automatic or manual adjustment.
In the present art, the measurement or calculation of the quantitative values of the fluids such as serum, blood etc. administered to the patients is realized by means of a single sensor system. In the system, pointwise region operation is performed. The measurement area consists of only a single plane, in the pointwise operation. In case a movement is made or a movement occurs based on any factor in the fluid bag to which the measurement device is connected, there is a possibility that the drop to be measured may not pass through the plane region. In this case, it leads to incorrect measurement of the fluid to be measured.
In the present art, the fluids cannot be tracked, measured or calculated when fluids are flowing continuously.
In the present art, the device which is connected to the fluid bag (chamber) and measures the fluid can shift from the chamber in case there is movement. Together with the shift of the device the chamber can close the sensor view with the fluid level. This conditions leads to incorrect measurement.
In the present art, after the fluid measurement is made, the doctor cannot be informed.
In the present art, the measured fluid cannot be remotely displayed and controlled.
During a research made in the present art, the application No TR2017/12793 is encountered. The application is a flow rate adjuster (1 ) mechanism which is mounted on the hoses used in supplementing blood, serum or fluid foods to the patient in the medical sector and provides controlling the flow rate of the fluid, comprising; fluid inlet line (5), fluid outlet line (6), fluid passage part (3) having a cylindrical body (4) positioned between said lines with one open end and one closed end, a flow rate adjustment part (2) which enables the user to intervene the flow rate by means of contacting, has flow rate male cylinder (2.1 ), can be mounted to the fluid passage part by means of the passage of the flow rate male cylinder (2.1 ) to the cylindrical body (4).

Operation principle of the invention
The infusion control system operates in 4 different modes;
Mode 1 , Continuous Trackino Mode: The continuous tracking mode is the mode which is required for starting of the operation of the device (A). The device (A) is located to the serum chamber (13.1 ) by means of compressing the serum chamber (13.1 ) via a gripping element (41 ) which has a mechanical force and can be opened and closed between the retainer front silicone part (14) and the retainer rear silicone part (15) located in the gripping region (4). EMR light waves generated from the transmitter source (2) are detected by means of at least two sensors (1 ). The signals generated as a result of the detection of the receiver sensors (1 ) are transmitted to the signal processing integrated circuit (3) or main processor (B) located on the device (A). The received signals are processed in the signal processing integrated circuit (3) or the processor (B), it is determined that the detected signals through the receiver sensors (1 ) in the signal processing integrated circuit (3) or the main processor (B) are at the same level In an overlapping manner.
Mode 2, The drops which pass through the serum chamber (13.1 ) leads to change in the light flux by the refraction of the EMR waves generated through the transmitter source (2). The waves with varying light flux are first of all detected by one of the receiver sensor (1 ) and subsequently by the other receiver sensor (1 ). The signals generated by the receiver sensors (1 ) as a result of the detection are transmitted to the signal processing integrated circuit (3) or the main processor (B). The main processor (B) or the signal processing integrated circuit (3) determines the speed of the drops and the total volume of the fluid by calculating the elapsed time.
Mode 3, Continuous Flow Mode: Since the drops that passes through the serum chamber (13.1 ) are in continuous flow (not in droplet form), the light flux based on the refraction of the waves generated from the transmitter source (2) does not change. The waves generated from the transmitter source (2) are detected as soon as the flow starts and ends in the receiving sensors (1 ). The receiver sensors (1 ) transmits the signals generated as a result of the detection to the signal processing integrated circuit (3) or the main processor (B). The speed and volume of the fluid is calculated by the signals processed in the signal processing integrated circuit (3) and the main processor (B) depending on the duration between the start and finish of the continuous flow.
Mode 4, Safety Mode: In case the serum (13) finishes and compresses blood in a reverse manner, in case the device (A) shifts from the serum chamber (13.1 ), the receiver sensors (1 ) terminates the measurement process and passes to the safety mode. The waves generated by the transmitter source (2) are not detected by the receiver sensors (1 ) because one of the views of the receiver sensors (1 ) is closed. In this case, signal voltage generated as a result of the detection of one of the receiver sensors (1 ) occurs in a minimum manner. In case the other receiver sensor (1 ) makes detection, because a comparison cannot be made between the receiver sensors (1 ) in the main processor (B) or the signal processing integrated circuit (3), measurement process cannot be performed. In case there is a high voltage shift in one of the receiver sensors (1 ) or in case one of the receiver sensors (1) is totally inactivated, the main processor (B) generates warning in the device (A) by means of determining this as a fault.
