Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an enteral nutrition infusion flow rate monitor with automatic tube flushing function. Background Art

[0002] An enteral nutrition infusion flow rate monitor refers to a device specifically designed to monitor the flow rate during enteral nutrition infusion. Through advanced technical means, this device can monitor and record the infusion speed of the nutrient solution in real time to ensure that patients receive appropriate nutritional supply. Its original design intention is to solve the problems of unstable flow rate and difficulty in precise control during traditional enteral nutrition infusion, thereby improving the treatment effect and comfort of patients. The enteral nutrition infusion flow rate monitor combines sensor technology, microprocessor control, and a user-friendly operation interface, enabling medical staff to easily set and adjust infusion parameters while monitoring abnormal situations during the infusion process in real time to ensure the safety of patients.

[0003] According to the patent document: CN215230433U, a pulsed automatic tube flushing infusion device is disclosed, which includes a nutrient solution bag, a flushing solution bag, a pressurized airbag bag, and a nutrition pump body. The nutrient solution bag and the flushing solution bag are respectively connected to a nutrient solution pipeline and a flushing solution pipeline. The other ends of the nutrient solution pipeline and the flushing solution pipeline are respectively connected to a three-way valve. The lower end of the three-way valve is connected to a pump tube wound around a circular pump wheel, passes through a filter, and is connected to the patient's enteral nutrition tube through a conical joint at the end of the confluence tube. A liquid stop valve and a medicine adding port are provided on the confluence tube; an inflatable airbag is installed in the nutrition pump body, and the flushing solution bag is pressurized through a driving component. An exhaust valve is installed on the airbag tube between the inflatable airbag and the pressurized airbag bag, and a pressure gauge is installed at one end close to the pressurized airbag bag. It realizes automatic pulsed flushing, reduces the workload of nursing staff, improves the flushing effect of the pipeline, further reduces the risk of pipeline blockage, and improves the quality and efficiency of clinical nursing work.

[0004] In current clinical medical operations, usually, a syringe is the only tool used to perform the pipeline flushing task. However, the front end opening size of the syringe often does not match the calibers of various types of nutrition pipelines, which results in an unsatisfactory sealing effect during use and thus easily leads to liquid leakage problems. In addition, the syringe has limited pressure generating ability. When a blockage occurs during the flushing process, the pressure inside the lumen will rapidly increase, forcing medical staff to apply more force to push the syringe in order to continue flushing. This not only increases the work difficulty but also significantly increases the workload, ultimately resulting in a double waste of time and energy. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides an enteral nutrition infusion flow rate monitor with automatic tube flushing. The technical problem to be solved by the present invention is that the syringe is the only tool used to perform the tube flushing task. However, the front-end opening size of the syringe often does not match the caliber of various types of nutritional tubes, which results in an unsatisfactory sealing effect during use and thus easily leads to the problem of liquid leakage. In addition, the syringe has limited ability to generate pressure. When a blockage occurs during the flushing process, the pressure inside the lumen will rise rapidly, forcing medical staff to apply more force to push the syringe in order to continue flushing. This not only increases the work difficulty but also significantly increases the workload, ultimately resulting in a double waste of time and energy.

A rotating rod 28 is fixedly connected to the front side of the second turntable 27. The outer wall of the rotating rod 28 extends to the inner wall of the flow splitting mechanism main body 21. The outer wall of the rotating rod 28 is rotatably connected to the bottom of the inner wall of the rear side of the flow splitting mechanism main body 21. A gear 29 is fixedly connected to one side of the outer wall of the rotating rod 28 at the rear side of the flow splitting mechanism main body 21. Rack bars 210 are slidably connected to the inner walls of the two slide bar grooves 23. The inner sides of the two rack bars 210 are respectively engaged with the outer walls on both sides of the gear 29.

At the inner bottom of each of the multiple spring connecting blocks 36, there is a U-shaped push rod 37 fixedly connected. The bottom inclination of the two U-shaped push rods 37 is opposite to that of the V-shaped rotating rods 34. Inside each of the two U-shaped push rods 37, there is a triangular abutting block 38 fixedly connected;

[0035] When nutritional infusion is required, first start the motor 24. The motor 24 drives the turntable 25 to rotate. The turntable 25 drives the second turntable 27 to rotate through the track 26. The second turntable 27 drives the rotating rod 28 to rotate. The rotating rod 28 drives the shunt block turntable 216 to rotate. The shunt block turntable 216 drives the L-shaped shunt baffle 217 to rotate through the second track 218, the second shunt block turntable 219, and the L-shaped shunt baffle rotating rod 2110. When the L-shaped shunt baffle 217 rotates inside the shunt mechanism main body 21, it can direct the cleaning liquid conveyed by the cleaning liquid infusion tube 213 or the nutrient solution conveyed by the nutrient solution tube 214 to the confluence tube 215, and convey it to the control pump wheel 13 through the confluence tube 215. The infusion flow rate is controlled by the control pump wheel 13. When the L-shaped shunt baffle 217 rotates to the left, it can direct the cleaning liquid conveyed by the nutrient solution tube 214 to the confluence tube 215. At this time, the cleaning liquid infusion tube 213 is blocked by the inclined surface of the L-shaped shunt baffle 217, so that the cleaning liquid infusion tube 213 pauses the conveyance of the nutrient solution. When the L-shaped shunt baffle 217 rotates to the right, it can direct the nutrient solution conveyed by the cleaning liquid infusion tube 213 to the confluence tube 215. At this time, the nutrient solution tube 214 is blocked by the inclined surface of the L-shaped shunt baffle 217, so that the nutrient solution tube 214 pauses the conveyance of the nutrient solution. Through the rotation of the L-shaped shunt baffle 217, the alternating conveyance of the cleaning liquid and the nutrient solution can be realized, avoiding the precipitation caused by the long-term stay of the nutrient solution in the conveying pipe. At the same time, the conveying pipe can be cleaned regularly to avoid the blockage of the conveying pipe, improving the practicability of the device;

[0036] When the motor 24 starts to rotate, while the shunt block turntable 216 and the L-shaped shunt baffle 217 shunt the cleaning liquid infusion tube 213 or the nutrient solution tube 214, the rotating rod 28 rotates and drives the gear 29 to rotate at the same time. When the gear 29 rotates, it meshes with the inner sides of the two rack bars 210, thereby driving the two rack bars 210 to slide on the inner wall of the chute rod 23. While the two rack bars 210 slide, they drive the two abutting blocks 211 to move. During the movement, the inclined cut surfaces of the two abutting blocks 211 will respectively contact and push the triangular abutting block 38 cut surfaces inside the two groups of U-shaped push rods 37 to drive the V-shaped rotating rod 34 to rotate. When the V-shaped rotating rod 34 rotates, it drives the clamping plate 35 to clamp or release the cleaning liquid infusion tube 213 or the nutrient solution tube 214. When the abutting block 211 disengages from the triangular abutting block 38, the spring 33 and the spring connecting block 36 cooperate to reset the V-shaped rotating rod 34;

[0037] Since the inner sides of the two rack bars 210 mesh with the outer wall of the gear 29, when the rotating rod 28 drives the L-shaped shunt baffle 217 to rotate to the left, the two rack bars 210 will slide to both sides respectively. At this time, the abutting block 211 on the right side pushes the triangular abutting block 38 inside the left U-shaped push rod 37, causing the V-shaped rotating rod 34 to rotate, and the clamping plate 35 clamps the nutrient solution tube 214, while the abutting block 211 on the left side disengages from the triangular abutting block 38 on the right side. The spring 33 and the spring connecting block 36 cooperate to reset the V-shaped rotating rod 34, causing the clamping plate 35 to release the cleaning liquid infusion tube 213. At this time, the nutrient solution tube 214 is clamped and fixed, and the cleaning liquid infusion tube 213 is in a free state. The cleaning liquid enters the confluence tube 215 through the guidance of the L-shaped shunt baffle 217;

[0038] Similarly, when the rotating rod 28 drives the L-shaped shunt baffle 217 to rotate to the right, the two rack bars 210 will also slide to both sides respectively. But at this time, the abutting block 211 on the left side pushes the triangular abutting block 38 inside the left U-shaped push rod 37, causing the clamping plate 35 to clamp the cleaning liquid infusion tube 213, while the abutting block 211 on the right side disengages from the triangular abutting block 38 on the left side. The spring 33 and the spring connecting block 36 cooperate to reset the V-shaped rotating rod 34, causing the clamping plate 35 to release the nutrient solution tube 214. At this time, the cleaning liquid infusion tube 213 is clamped and fixed, and the nutrient solution tube 214 is in a free state. The nutrient solution enters the confluence tube 215 through the guidance of the L-shaped shunt baffle 217. Through this design, the alternate clamping and releasing of the cleaning liquid infusion tube 213 and the nutrient solution tube 214 can be realized, ensuring that the corresponding pipeline can be stably clamped and fixed during the transportation of the cleaning liquid or the nutrient solution, avoiding the continuous outflow of the liquid in the pipeline, while the unused pipeline is in a free state, avoiding unnecessary liquid flow, improving the infusion accuracy and efficiency. In addition, this design also helps to reduce the infusion interruption caused by the pipeline vibration or movement, further enhancing the stability and reliability of the device.

[0039] Working principle of the present invention: When nutritional infusion is required, the motor 24 is first started. The motor 24 drives the turntable 25 to rotate. The turntable 25 drives the second turntable 27 to rotate through the crawler 26. The second turntable 27 drives the rotating rod 28 to rotate. The rotating rod 28 drives the shunt block turntable 216 to rotate. The shunt block turntable 216 drives the L-shaped shunt baffle 217 to rotate through the second crawler 218, the second shunt block turntable 219, and the L-shaped shunt baffle rotating rod 2110. When the L-shaped shunt baffle 217 rotates inside the main body 21 of the shunt mechanism, it can direct the cleaning liquid conveyed by the cleaning liquid infusion pipe 213 or the nutrient solution conveyed by the nutrient solution pipe 214 to the confluence pipe 215, and convey it to the control pump wheel 13 through the confluence pipe 215. The infusion flow rate is controlled by the control pump wheel 13. When the L-shaped shunt baffle 217 rotates to the left, the cleaning liquid conveyed by the nutrient solution pipe 214 can be directed to the confluence pipe 215. At this time, the cleaning liquid infusion pipe 213 is blocked by the inclined surface of the L-shaped shunt baffle 217, so that the cleaning liquid infusion pipe 213 pauses the conveyance of the nutrient solution. When the L-shaped shunt baffle 217 rotates to the right, the nutrient solution conveyed by the cleaning liquid infusion pipe 213 can be directed to the confluence pipe 215. At this time, the nutrient solution pipe 214 is blocked by the inclined surface of the L-shaped shunt baffle 217, so that the nutrient solution pipe 214 pauses the conveyance of the nutrient solution. By rotating the L-shaped shunt baffle 217, the alternating conveyance of the cleaning liquid and the nutrient solution can be realized, avoiding the precipitation of the nutrient solution caused by staying in the conveying pipe for a long time. At the same time, the conveying pipe can be cleaned regularly to avoid the blockage of the conveying pipe, improving the practicability of the device. When the motor 24 starts to rotate and the shunt block turntable 216 and the L-shaped shunt baffle 217 shunt the cleaning liquid infusion pipe 213 or the nutrient solution pipe 214, the rotating rod 28 rotates and drives the gear 29 to rotate at the same time. When the gear 29 rotates, it meshes with the inner sides of the two rack bars 210, thereby driving the two rack bars 210 to slide on the inner wall of the chute rod 23. When the two rack bars 210 slide, they drive the two abutting blocks 211 to move. The inclined cut surfaces of the two abutting blocks 211 will respectively contact and push the triangular abutting block 38 cut surfaces inside the two U-shaped push rods 37 during the movement process, driving the V-shaped rotating rod 34 to rotate. When the V-shaped rotating rod 34 rotates, it drives the clamping plate 35 to clamp or release the cleaning liquid infusion pipe 213 or the nutrient solution pipe 214. When the abutting block 211 disengages from the triangular abutting block 38, the spring 33 cooperates with the spring connection block 36 to reset the V-shaped rotating rod 34. Since the inner sides of the two rack bars 210 mesh with the outer wall of the gear 29, when the rotating rod 28 drives the L-shaped shunt baffle 217 to rotate to the left, the two rack bars 210 will slide to both sides respectively. At this time, the right abutting block 211 pushes the triangular abutting block 38 inside the left U-shaped push rod 37, causing the V-shaped rotating rod 34 to rotate, and the clamping plate 35 clamps the nutrient solution pipe 214, while the left abutting block 211 disengages from the triangular abutting block 38 on the right, and the spring 33 cooperates with the spring connection block 36 to reset the V-shaped rotating rod 34, causing the clamping plate 35 to release the cleaning liquid infusion pipe 213. At this time, the nutrient solution pipe 214 is clamped and fixed.The cleaning liquid infusion tube 213 is in a free state. The cleaning liquid enters the confluence tube 215 under the guidance of the L-shaped diversion baffle 217. Similarly, when the rotating rod 28 drives the L-shaped diversion baffle 217 to rotate to the right, the two rack bars 210 will also slide to both sides respectively. However, at this time, the left abutting block 211 pushes the triangular abutting block 38 in the left U-shaped push rod 37, so that the clamping plate 35 clamps the cleaning liquid infusion tube 213, while the right abutting block 211 disengages from the left triangular abutting block 38, and the spring 33 cooperates with the spring connecting block 36 to reset the V-shaped rotating rod 34, so that the clamping plate 35 releases the nutrient solution tube 214. At this time, the cleaning liquid infusion tube 213 is clamped and fixed, and the nutrient solution tube 214 is in a free state. The nutrient solution enters the confluence tube 215 under the guidance of the L-shaped diversion baffle 217. Through this design, the alternative clamping and release of the cleaning liquid infusion tube 213 and the nutrient solution tube 214 can be realized.
