AUTOMATIC TRANSFUSION STOP AND SAFETY SYSTEM

Abstract

This invention is an automated flow control system developed to ensure patient safety during blood and blood product transfusions in the healthcare sector. The system consists of a temperature sensor (2) that detects sudden changes in the patient's body temperature, a microcontroller (3) that continuously monitors the data from the sensor, a servo motor (4) mechanism that physically cuts off the flow when a risk is detected, and audible / visual warning units (5). The working principle (Figure 2) is based on triggering the motor to compress the hose and cut off the flow if the temperature goes outside the safe range. In this way, complications are prevented without the need for intervention by healthcare personnel.

Description

1 TARIFF AUTOMATIC TRANSFUSION STOP AND SAFETY SYSTEM 1. Technical Scope of the Invention This invention relates to the transfusion of blood and blood products in the healthcare sector. detecting potential complications early on and maintaining the transfusion flow It relates to a safety system that stops automatically. 5 2. State of the Art In current practices, risks that may develop during blood transfusions Monitoring reactions relies entirely on the nurse's observation and vital sign tracking. Although most reactions occur within the first 15 minutes, current standard blood tests... Their systems do not have a mechanism to detect this situation and automatically stop the flow. Manual clamps or taps used to cut off the flow may cause symptoms such as a rise in patient fever. They are unable to automatically respond to physiological changes. This leads to delays in intervention and This increases the risk of complications. 3. Purpose of the Invention The purpose of this invention is to treat conditions such as increased temperature in a patient during transfusion. especially to detect early signs of complications through sensors and in humans The goal is to mechanically stop blood flow without requiring intervention. This allows for a possible 15 The aim is to reduce the risk of injury and death. 4. Explanation of Figures The attached figures should be used as a reference for a better understanding of the invention. • Figure 1: Perspective drawing showing the overall view and components of the system. • Figure 2: Workflow diagram showing the system's decision-making and operational logic. 5.

Servo Motor (Flow Shut-off Mechanism) 25 5. Warning Unit (LED and Buzzer) 6. Power Switch and Power Supply 2 The steps in the flowchart shown in Figure 2 are numbered below: 1. System activation 2. Temperature detection using a heat sensor. 3. Data transmission to the microcontroller. 4. Temperature safe range control 5 5. Activation of the warning unit 6. Triggering the servo motor 7. Interruption of flow 6. Detailed Description of the Invention The invention is a portable safety system that can be integrated into blood transfusion sets. It is related to. The system consists of a main body (1) that houses the components, and a system that receives temperature data from the patient. a heat sensor (2), a microcontroller (3) that processes this data, a physical stops the flow The system includes a servo motor (4) and a warning unit (5) that provides audible and / or visual warning. It is operated via a power switch and power supply (6). A preferred application of the invention is as follows, according to the flowchart shown in Figure 2: 15 It has been explained. The system is activated in step (1). After the system is activated, (2) In step number [number], the patient's body temperature is detected via a heat sensor. The detected temperature The information is transmitted as data to the microcontroller in step (3). The microcontroller takes the temperature information received in control stage (4) in advance 20 It assesses whether it is within the defined safe range. This safe range is 36°–38°. The temperature values ​​are within this range. The microcontroller processes the data from the sensor in real time. It performs this check continuously. If the temperature value remains within the safe range, the system continues the monitoring cycle and Return to step (2). 25 However, if a reaction develops in the patient and the temperature falls outside the safe range... In this case, the microcontroller initiates the critical action process in step (4). This In this case, warning unit (5) is activated and produces a visual and / or auditory warning. Warning 3 Within the scope of the unit, a flashing LED and an audible buzzer alarm alert healthcare personnel. It informs. Following the activation of the warning unit, the servo motor is triggered in step (6). Servo The motor compresses the serum tube via the mechanism attached to its end and in step (7) It physically cuts off blood flow. This prevents potential complications. 5 After the flow is interrupted, the system is shut down and enters intervention waiting mode. This Thanks to the automated system, there is no need for healthcare personnel to be constantly present at the patient's bedside. Without this, patient safety can be effectively ensured.
