Description

1 TARIFF INFUSION FLOW REGULATOR WITH LOCK MECHANISM Technical Area The invention relates to a flow regulator for medical devices and intravenous (IV) infusion systems. It is related. 5 The invention is particularly suitable for hospitals, intensive care units, emergency departments, clinics, and home healthcare. In intravenous fluid and drug delivery systems used in services, infusion flow the rate is safely adjusted and the infusion fluid is controlled to ensure it reaches the patient. It relates to a locking mechanism infusion flow regulator that enables the delivery of the correct amount of infusion. State of the Art 10 Intravenous (IV) infusion systems deliver fluids, medications, nutrients, or similar substances to a patient. These are systems that enable controlled administration of blood intravenously. In these systems, the flow... Rate is an important factor in determining the amount of fluid to be given to the patient within a specific time interval. This is a parameter. Proper adjustment of the flow rate ensures the correct dosage of medication or liquid. and is important in terms of safe application. Flow rate, for example mL / hour or 15 It can be expressed in drops per minute. Flow rate control in intravenous infusion systems in the known state of the art. Typically, roller clamps, slide regulators, or microflow controls are used. This is achieved through various mechanisms. Widely used in clinical practice. In these systems used, the infusion rate determined by healthcare personnel is; patient 20 movement, involuntary contact, hose elasticity, loss of friction, or patient / patient caregiver It is known that it can change due to the intervention. Especially long-term intravenous In treatments, failure to maintain the set flow rate affects drug safety and treatment efficacy. In summary, current techniques can pose significant clinical risks. The disadvantages are as follows: 25 - Inability to reliably maintain the set flow rate, - The inability to completely prevent unauthorized interventions, - Possible dose changes due to accidental contact, 2 - Additional accessories or removable parts may create complexity in use, - Quickly shows healthcare personnel that safety mode is active. lack of a visual verification mechanism As a result of the research, EP4674450A1 was encountered in relation to the subject. The document states that the regulator has a screw-tightening locking mechanism integrated into it, 5 It appears that the rotation of the lower body is restricted. In this system, locking is achieved; This is achieved through a mechanical structure based on the principles of compression and friction, and also through optics. electronic components such as sensors, infrared sensors, laser sensors and management servers Flow measurement and infusion monitoring are performed with this system. However, the system in question needs to be redesigned. It operates on a lock-and-unlock principle, completely restricting user access. It does not offer a clinically safety-focused structure. Furthermore, it includes sensors, control modules, and data. Cost and system complexity due to the need for management infrastructure. It constitutes. Another document encountered during the research is CN213491169U. The relevant document... The document states that the adjustment mechanism is self-adjusting with spring-assisted friction elements. The aim is to stabilize it. In these systems, the regulator may slip or automatically return. Efforts have been made to prevent its reversal. However, in these mechanisms, the user movable key or clamping mechanisms that can be released again because of its presence, a robust security workflow aimed at reducing unauthorized access. It is not defined. Therefore, readjustment by the patient or their relative is required. 20 The risk of it being possible remains. Another document encountered in the literature is KR102890261B1.

The operating principle of the flow regulator, which is the subject of this invention, is as follows: First, the desired infusion is determined by turning the flow adjustment wheel (5) by the healthcare personnel. The speed is determined by the rotation of the flow adjustment wheel (5) inside the inner body (12). The amount of compression on the flow channel (9) changes, thus intravenous 20 The flow rate of the liquid is adjusted. The click dosing system (11) adjusts the flow adjustment wheel (5) at certain points. by helping to keep the body stable in certain positions, preventing involuntary slipping or It reduces flow variations caused by friction. After the desired flow rate is determined... then the top-press safety cap (2) is activated and the system enters safety mode It is passed through. Mechanical 25 by applying controlled pressure to the safety cap (2). The blocking pin (6) moves downwards, releasing the flow adjustment wheel (5) again. This limits its rotation. Thus, the set dose value is maintained. is the goal. The flow regulator (18) that is the subject of the invention incorporates a two-stage safety approach. First Thanks to the security layer, security seal (3) and controlled activation structure, involuntary 30 or is aimed at reducing accidental activation. The second layer of security is mechanical. This pair ensures that the flow rate set via the blocking pin (6) is maintained. Thanks to the security approach, both accidental and involuntary security activations are prevented. 7 Dose variation is reduced. Visual lock when safety mode is activated. The indicator (4) changes color to inform healthcare personnel that the system is in protection mode. It provides the possibility of rapid verification. Thus, the user can verify the infusion system. They can directly assess the security status through the device. The microflow bed (8) and stabilization chamber (10) work together to reduce the sudden 5 in fluid flow. This helps to reduce variations, especially in low-flow applications. It supports the achievement of stable infusion flow.
