Description

Technical Field

[0001] This invention relates to the field of critical care equipment technology, specifically to a self-balancing liquid feeding device for critical care. Background Technology

[0002] In the field of critical care, liquid feeding is a core means of ensuring nutritional intake for patients unable to eat independently, and the appropriateness of the feeding device directly affects the patient's feeding safety, comfort, and the efficiency of nursing care. However, current liquid feeding devices used in clinical practice still have many problems that urgently need to be solved, making it difficult to meet the special nursing needs of critically ill patients.

[0003] Existing liquid feeding devices are mostly passive, leaving patients with little autonomy in feeding. Traditional devices typically deliver liquids manually via an infusion-like switch or a push-button mechanism controlled by healthcare professionals. Patients cannot control the feeding process based on their own swallowing rhythm or satiety, often remaining in a passive state. This not only easily leads to psychological resistance but can also cause choking, aspiration, or even life-threatening situations due to the feeding speed not matching the patient's swallowing ability. Furthermore, current technology has significant shortcomings in terms of device stability and angle adaptability. Most feeding devices are installed using fixed brackets or simple suspension methods, lacking a support structure adapted to the patient's body contours. Even slight movements or head tilts by the patient can cause the device to shift or the feeding tube to detach, interrupting the feeding process and potentially causing liquid leakage and contamination of the bed. Therefore, it is necessary to propose a self-balancing liquid feeding device for intensive care. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a self-balancing liquid feeding device for critical care.

A feeding tube is fixedly installed on the block, and a delivery hose is fixedly installed at the lower end of the storage cylinder. The lower end of the delivery hose extends through into the feeding tube. Two openings are opened on the feeding tube, and clamping blocks are slidably connected to each of the two openings. Limiting holes are opened through each of the two clamping blocks, and limiting rods are slidably connected to each of the limiting holes. One end of the limiting rod extends outside the two clamping blocks and is fixedly connected to a push plate. The other end of the limiting rod extends between the clamping blocks and is fixedly connected to the clamping blocks. A spring is sleeved on the limiting rod, and the two ends of the spring are fixedly connected to the clamping blocks and the push plate, respectively.

[0006] Specifically, the pressing component includes a fixed sleeve, which is fixedly installed on the upper end of the arc-shaped support frame. A fixed rod is slidably connected inside the fixed sleeve. A tension spring is fixedly connected to the upper surface of the arc-shaped support frame inside the fixed sleeve. The upper end of the tension spring is fixedly connected to the fixed rod. A mounting bracket is fixedly connected to the upper end of the fixed rod. A rotating hole is provided through the mounting bracket.

[0007] Specifically, the rotating rod is sleeved inside the rotating hole, and the fixed sleeve, fixed rod, pressing rod, and storage cylinder are all arranged vertically.

[0008] Specifically, the heat preservation component includes a heating coil and a temperature sensor. The bottom end of the storage cylinder has an installation cavity, and the heating coil is fixedly installed in the installation cavity on the storage cylinder. The temperature sensor is fixedly installed on the inner wall of the storage cylinder.

[0009] Specifically, the lower end of the arc-shaped support frame is fixedly equipped with a support leg, and the support leg is set at a right angle to the arc-shaped support frame.

[0010] Specifically, the upper end of the delivery hose is fixedly connected to the lower surface of the storage cylinder, and the upper end of the delivery hose is connected to the inner cavity of the storage cylinder, while the lower end of the delivery hose extends through to the lower opening of the feeding tube.

[0011] Specifically, arc-shaped grooves are provided on the sidewalls of the two push plates on the side away from each other, and the edges of the arc-shaped grooves are set in a curved shape.

[0012] Specifically, the sidewalls of the two clamping blocks extend into the feeding tube on opposite sides, and the sidewalls of the clamping blocks inside the feeding tube are clamped onto the delivery hose.

[0013] Specifically, the T-shaped slide is arc-shaped, and the lower end of the T-shaped slider is located outside the arc-shaped support frame and extends outward.

[0014] The beneficial effects of this invention are as follows: The self-balancing liquid feeding device for intensive care described in this invention, through a linkage structure composed of clamping blocks and limiting rods on the feeding tube, allows patients to autonomously control the feeding process by simply closing and opening their lips, freeing them from passive dependence and maintaining the dignity of eating. A stable support is formed by an arc-shaped support frame and right-angled feet, and the matching design of an arc-shaped T-shaped groove and T-shaped slider allows the feeding tube to adjust its angle synchronously with head rotation, and can also be switched to side-feeding, reducing the risk of aspiration and choking, and ensuring safe and comfortable feeding. A pressure component composed of a fixed sleeve, tension spring, and heat preservation assembly achieves semi-automatic feeding and liquid food heat preservation. The tension spring automatically drives the pressure plate to squeeze the liquid food, eliminating the need for continuous operation by medical staff. Simultaneously, the rotatable design of the rotating rod makes liquid food dispensing convenient and efficient, significantly reducing the nursing burden. It is suitable for various complex nursing scenarios such as intensive care units and general wards, ensuring reliable use. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: A self-balancing liquid feeding device for intensive care includes an arc-shaped support frame 1. A storage cylinder 2 is fixedly installed on the upper surface of the arc-shaped support frame 1. An insulation component is installed inside the storage cylinder 2. A lower pressure plate 3 is slidably connected inside the storage cylinder 2. A lower pressure rod 4 is fixedly connected to the upper surface of the lower pressure plate 3. A lower pressure component is fixedly installed at the upper end of the arc-shaped support frame 1. A rotating rod 5 is slidably connected to the lower pressure component. The rotating rod 5 is fixedly connected to the lower pressure rod 4. A T-shaped groove 6 is formed on the lower surface of the arc-shaped support frame 1. A T-shaped slider 7 is slidably connected in the T-shaped groove 6. A feeding tube 8 is fixedly installed on the T-shaped slider 7. The lower end of the storage cylinder 2 is fixedly... A delivery hose 9 is fixedly installed, with its lower end extending through into a feeding tube 8. The feeding tube 8 has two openings 10, and each opening 10 is slidably connected to a clamping block 11. Each clamping block 11 has a limit hole 12, and each limit hole 12 is slidably connected to a limit rod 13. One end of the limit rod 13 extends outside the two clamping blocks 11 and is fixedly connected to a push plate 14. The other end of the limit rod 13 extends between the clamping blocks 11 and is fixedly connected to the clamping blocks 11. A spring 15 is sleeved on the limit rod 13, and both ends of the spring 15 are fixedly connected to the clamping block 11 and the push plate 14, respectively. When using it, the following steps are included: First, place the arc-shaped support frame 1 at the neck position, and place the support leg 21 on the hospital bed to support the arc-shaped support frame 1. Then, hold the push block 14 in your mouth and bite your lips into the arc-shaped groove 22 on the push block 14. Step 2: Pull the rotating rod 5 upwards. The rotating rod 5 will drive the lower pressure rod 4 and the lower pressure plate 3 to rise until the lower pressure plate 3 is separated from the storage cylinder 2. At this time, the rotating rod 5 can be rotated. The rotating rod 5 will drive the lower pressure rod 4 and the lower pressure plate 3 to rotate, so that the lower pressure plate 3 is separated from the opening of the storage cylinder 2. At this time, liquid food can be injected into the storage cylinder 2. After filling it to 85%, the lower pressure plate 3 can be reset by rotating the rotating rod 5. Third step: At this time, the heating coil 23 and temperature sensor 24 are connected to the signal of the external smart device. The temperature sensor 24 detects the real-time temperature of the liquid food in the storage cylinder 2. When the temperature is too low, the heating coil 23 can be activated to keep the liquid food in the storage cylinder 2 warm. At the same time, the tension spring 18 pulls the fixing rod 17 down. The fixing rod 17 descends vertically in the fixing sleeve 16. The fixing rod 17 drives the mounting frame 19 to descend synchronously. The mounting frame 19 drives the rotating rod 5 to descend synchronously through the rotating hole 20. The rotating rod 5 drives the lower pressure plate 3 to descend synchronously through the lower pressure rod 4 and squeezes the liquid food in the storage cylinder 2, so that the liquid food in the storage cylinder 2 is forced into the delivery hose 9. Fourth step: When the lips are closed, the pusher block 14 will be pushed, and the pusher block 14 will push the clamping block 11 through the limit rod 13, so that the clamping block 11 moves out of the opening 10 and releases the clamp on the lower end of the delivery hose 9, thereby releasing the seal on the delivery hose 9. At this time, the liquid food entering the delivery hose 9 can flow and flow into the user's mouth. When the user feels that there is enough liquid food, he / she can open his / her mouth. At this time, the spring 15 will push the pusher block 14 and the clamping block 11, so that the clamping block 11 resets and clamps and seals the lower end of the delivery hose 9, so that the user can freely control the feeding. Fifthly, during use, the user can tilt their head, and the T-shaped slider 7 rotates within the T-shaped groove 6, thereby causing the feeding tube 8 to rotate synchronously, so that the feeding tube 8 follows the head in angle adjustment and maintains feeding; secondly, after the angle of the feeding tube 8 is adjusted, the user can first release the mouth from the contact with the push block 14, at which point the head can be straightened, and then the push block 14 can be held in the mouth on the side, so that the feeding tube 8 will be located on the side of the mouth for feeding, avoiding liquid food flowing directly into the throat in the middle and causing discomfort to the user.

[0020] Example 2: The technical solutions in this example that differ from Example 1 include: The pressing assembly includes a fixed sleeve 16, which is fixedly installed on the upper end of the arc-shaped support frame 1. A fixed rod 17 is slidably connected inside the fixed sleeve 16. A tension spring 18 is fixedly connected to the upper surface of the arc-shaped support frame 1 inside the fixed sleeve 16. The upper end of the tension spring 18 is fixedly connected to the fixed rod 17. A mounting bracket 19 is fixedly connected to the upper end of the fixed rod 17. A rotating hole 20 is opened through the mounting bracket 19, and a rotating rod 5 is sleeved in the rotating hole 20. The fixed sleeve 16, fixed rod 17, pressing rod 4, and storage cylinder 2 are all arranged vertically. The heat preservation assembly includes a heating coil 23 and a temperature sensor 24. A mounting cavity is provided inside the bottom end of the storage cylinder 2, and the heating coil 23 is fixedly installed in the mounting cavity on the storage cylinder 2. The temperature sensor... 24 is fixedly installed on the inner wall of the storage cylinder 2. The heating coil 23 and temperature sensor 24 are connected to the signal of an external smart device. The temperature sensor 24 detects the real-time temperature of the liquid food in the storage cylinder 2. When the temperature is too low, the heating coil 23 can be activated to keep the liquid food in the storage cylinder 2 warm. The rotating rod 5 can be rotated, which drives the lower pressure rod 4 and the lower pressure plate 3 to rotate, causing the lower pressure plate 3 to disengage from the opening of the storage cylinder 2. At this time, liquid food can be injected into the storage cylinder 2. After it is filled to 85%, the lower pressure plate 3 can be reset by rotating the rotating rod 5. At this time, the tension spring 18 will pull the fixing rod 17 down. The fixing rod 17 descends vertically inside the fixing sleeve 16. The fixing rod 17 will drive the mounting bracket 19 to descend synchronously. The mounting frame 19 lowers the rotating rod 5 synchronously via the rotating hole 20. The rotating rod 5, in turn, lowers the pressure plate 3 synchronously via the pressure rod 4, squeezing the liquid food in the storage cylinder 2 and forcing it into the delivery hose 9. A support leg 21 is fixedly installed at the lower end of the arc-shaped support frame 1, forming a right angle with it. The arc-shaped support frame 1 is placed at the neck position, while the support leg 21 is placed on the bed to support it. The upper end of the delivery hose 9 is fixedly connected to the lower surface of the storage cylinder 2, and the upper end of the delivery hose 9 communicates with the inner cavity of the storage cylinder 2. The lower end of the delivery hose 9 extends through to the lower opening of the feeding tube 8. The liquid food in the storage cylinder 2 is forced into the delivery hose 9 and then transported through the tube. The feeding tube 9 delivers the feed to the lower end of the feeding tube 8, and then flows into the user's mouth. The two push plates 14 are provided with arc-shaped grooves 22 on the side walls of the opposite sides. The edges of the arc-shaped grooves 22 are set in a curved shape, so that the user can hold the push block in their mouth. The two clamping blocks 11 extend into the feeding tube 8 from the side walls of the opposite sides. The clamping blocks 11 are located on the side walls of the feeding tube 8 and clamp the feeding tube 9. The lower end of the feeding tube 9 is closed by clamping the feeding tube 9 with the clamping blocks 11. The T-shaped slide 6 is set in an arc shape. The lower end of the T-shaped slider 7 is located outside the arc-shaped support frame 1 and extends outward, so that the feeding tube 8 can move along the track of the T-shaped slide 6 through the T-shaped slider 7, thereby adjusting the direction and angle.
