Description

Technical Field

[0001] The utility model relates to a flow rate detection and control device for a medical infusion tube, in particular to an automatic flow rate detection and control device for a medical infusion tube. Background Art

[0002] Medical infusion tubing, commonly referred to as disposable IV infusion sets, is a vital medical consumable that undergoes sterile processing. It is primarily used to establish a pathway between the vein and medication, enabling intravenous infusion to meet patient treatment needs. Medical infusion tubing typically consists of multiple connected components, including an IV needle or injection needle, a needle cap, an infusion hose, a medication filter, a flow regulator, a drip pot, a bottle stopper puncture device, and an air filter. Some infusion sets are also equipped with additional functional components such as injection devices and dosing ports. Under atmospheric pressure, the liquid in the bottle flows through the thin infusion hose into the drip chamber. When the water column pressure in the drip chamber exceeds the venous pressure, the liquid in the bottle flows through the hose into the vein. The flow regulator controls the infusion rate to ensure accurate infusion and patient comfort.

[0003] Traditional infusion flow rate regulators mainly rely on mechanical principles to control the infusion speed. These regulators usually squeeze the infusion line by sliding buttons or rotating regulators to change the size of the liquid diameter. According to the principles of fluid dynamics, the larger the diameter, the smaller the resistance generated by the pipeline and the faster the flow rate; conversely, the smaller the diameter, the greater the resistance and the slower the flow rate.

[0004] However, traditional infusion flow rate regulators are generally only adjustable mechanically, without stepless adjustment. Their adjustment range and precision are limited, thus restricting medical staff's ability to fine-tune the flow rate based on the patient's specific condition and medication properties. Furthermore, due to their limited adjustment precision and single adjustment method, traditional infusion flow rate regulators are prone to over- or under-infusion, increasing the risk of adverse reactions in patients.

[0049] like Figure 4 As shown, the fixed cover mechanism 2 includes: a second positioning member 2.4, a second baffle 2.5 and a second heating member 2.6 installed and fixed in the fixed cover mechanism 2; the first positioning member 1.1 and the second positioning member 2.4, the first baffle 1.2 and the second baffle 2.5, the first heating member 1.3 and the second heating member 2.6 correspond one to one, the second baffle 2.5 is slidably connected to the fixed cover mechanism 2, and a second notch 2.7 is provided at both ends of the fixed cover mechanism 2.

[0050] The fixed cover mechanism 2 further includes: a switch member 2.1, a warning light 2.2, and an adjusting air pump 2.3 for adjusting the position of the second flow-blocking member 2.5; the switch member 2.1, the warning light 2.2, and the adjusting air pump 2.3 are all uniformly controlled by an intelligent control system. The adjusting air pump 2.3 is used to adjust the position of the second flow-blocking member 2.5, so that the distance between the first flow-blocking member 1.2 and the second flow-blocking member 2.5 is reduced, and the infusion tube is squeezed between the first flow-blocking member 1.2 and the second flow-blocking member 2.5.

[0051] Furthermore, medical staff or patients can change the power supply of the intelligent control system by pressing the switch 2.1 independently.

[0052] like Figure 6As shown, the second positioning member 2.4 includes: a third positioning plate 2.4.1, a fourth positioning plate 2.4.2, a second positioning arc plate 2.4.3 and a guide rail 2.4.8; the third positioning plate 2.4.1 corresponds to the first positioning plate 1.1.1, the fourth positioning plate 2.4.2 corresponds to the second positioning plate 1.1.2, and the second positioning arc plate 2.4.3 corresponds to the first positioning arc plate 1.1.3.

When the second positioning member 2.4 abuts the first positioning member 1.1, the guide rail 2.4.8 can be embedded in the guide groove 1.1.8.

[0053] A first resistance-increasing pad 1.1.4 is provided at the first positioning arc plate 1.1.3, and a second resistance-increasing pad 2.4.4 is provided at the second positioning arc plate 2.4.3. The first resistance-increasing pad 1.1.4 and the second resistance-increasing pad 2.4.4 are both hollow. The first resistance-increasing pad 1.1.4 and the second resistance-increasing pad 2.4.4 are both made of rubber or silicone. The ends of the first fixing block 1.1.5 and the second fixing block 2.4.5 are respectively sleeved with the first anti-slip plate 1.1.7 and the second anti-slip plate 2.4.7.

The rubber material of the first baffle 12. and the second baffle 2.5 has excellent elasticity and sealing properties, which can effectively squeeze the infusion tube and control the flow rate of the liquid medicine. At the same time, the outer diameter of the bottom of the second baffle 2.5 is consistent with the inner diameter of the top of the first baffle 1.2, ensuring a tight fit between the baffles and a stable flow blocking effect.

[0055] A power storage box 1.3.1 is provided on the side of the first heating element 1.3 and the second heating element 2.6. A heating wire 1.3.2 electrically connected to the power storage box 1.3.1 is provided on the first heating element 1.3 and the second heating element 2.6.

[0056] The positioning hole 4 is composed of a first notch 1.5 and a second notch 2.7.

These reset elements 6 comprise a reset frame 6.1, a reset pin 6.2, a third reset spring 6.3, and a keypad 6.4. Pressing the keypad 6.4 disengages the reset pin 6.2 from the through-hole 1.9, separating the fixed frame mechanism 1 from the fixed cover mechanism 2. The reset elements 6 facilitate unlocking during disassembly, and the third reset spring 6.3 quickly returns the reset pin 6.2 to its initial position, facilitating repeated use and maintenance of the device and improving its efficiency.

[0060] When the present invention is used, the fixing frame mechanism 1 is first firmly fixed to the arm of the human body using the strap 3 to ensure that the device does not move during use, and then the infusion tube is placed in the first arc-shaped groove of the first positioning member 1.1, the first flow blocking member 1.2 and the first heating member 1.3 in the fixing frame mechanism 1; when the fixing cover mechanism 2 is covered, the second positioning member 2.4, the second flow blocking member 2.5 and the second heating member 2.6 inside it closely correspond to the corresponding components in the fixing frame mechanism 1, and together they firmly clamp the infusion tube.

[0061] The second flow blocker 2.5 is slidably connected to the fixed cover mechanism 2 and its position can be adjusted by adjusting the air pump 2.3 to reduce the distance between the first flow blocker 1.2 and the second flow blocker 2.5, thereby firmly squeezing the infusion tube therebetween.

[0062] The integrated sensor 1.4 monitors the flow rate of the liquid medicine in the infusion tube in real time and transmits the data to the intelligent control system in the control unit in real time. The intelligent control system controls the flow rate of the liquid medicine in the infusion tube by adjusting the distance between the first flow blocker 1.2 and the second flow blocker 2.5 according to a preset flow rate range.

[0063] If no liquid medicine flows through the infusion tube, the intelligent control system immediately triggers the warning light 2.2 to issue a warning and automatically adjusts the distance between the first flow blocker 1.2 and the second flow blocker 2.5 to achieve automatic blocking. Furthermore, to disassemble the device, simply press the keypad 6.4 in the reset member 6. The reset bolt 6.2 will eject the positioning pin 2.9 located in the through hole 1.9, thereby easily releasing the lock between the fixed frame mechanism 1 and the fixed cover mechanism 2.

[0064] The device provided by the utility model realizes automatic detection and control of the flow rate and temperature of the infusion tube through the coordinated work of components such as the intelligent control system, the heating element, the flow blocking element and the sensor, thereby ensuring the safety and accuracy of the infusion process.
