Description

Technical Field

[0001] This invention relates to the field of postoperative care technology, specifically to an enteral nutrition infusion device and method for postoperative care after intestinal anastomosis. Background Technology

[0002] Enteral nutrition has become the preferred nutritional support method after intestinal anastomosis due to its advantages such as conforming to physiological conditions, maintaining intestinal barrier function, and reducing complications. Enteral nutrition delivery devices typically consist of a nutrient solution container, delivery tubing, flow control device (such as a nutrient pump), and nasoenteric tube.

[0003] However, enteral nutrition solutions are mostly complex suspensions or emulsions. The large molecules they contain, such as proteins and dietary fiber, are prone to cross-linking and aggregation when temperature, pH, or flow rate changes occur, forming tiny particles. Furthermore, some medications, if incompatible with the nutrition solution, can also produce precipitates. During continuous infusion, these particles and precipitates easily adhere to and deposit on the inner walls of the delivery tube and nasoenteric tube, gradually leading to narrowing or even complete blockage of the lumen. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an enteral nutrition input device and method for postoperative care after intestinal anastomosis, so as to solve the problem in the prior art that during continuous infusion, particulate matter and sediment are easily attached and deposited on the inner wall of the lumen when flowing through the delivery tube and nasoenteric tube, which gradually leads to stenosis of the lumen and even complete blockage.

[0005] This invention is achieved through the following technical solution: An enteral nutrition delivery device for postoperative care after intestinal anastomosis includes a support rod and a delivery tube with one end connected to a nasoenteric tube. An insulated box is detachably fixed to the support rod. An insulated cover is sealed to the top of the insulated box.

By rotating the first connecting rod and the planar thread, the multiple sliding rods can be simultaneously driven to slide radially synchronously along their length. The end of the slide rod away from the first rotating shaft is fixedly connected to a hemispherical protrusion. When the slide rod slides radially to the outermost end, the protrusion can abut against and squeeze the wall of the delivery pipe located in the slot.

The output end of the three-way valve 8 is connected to the delivery tube 2. The two input ends of the three-way valve 8 are respectively connected to the first connecting pipe 9 and the second connecting pipe 10. The end of the first connecting pipe 9 away from the three-way valve 8 is connected to the first cavity 6, and the end of the second connecting pipe 10 away from the three-way valve 8 is connected to the second cavity 7. A pusher assembly 11 is slidably connected inside the second cavity 7, and the pusher assembly 11 is used to push warm water into the delivery pipe 2.

[0026] The bottom of the heat preservation box 3 is fixedly connected to an installation plate 12. The installation plate 12 has a slot 13 for accommodating and fixing the conveying pipe 2. The slot 13 is formed by splicing two arc segments into an S shape. Two flow rate adjustment components 14 are installed on the installation plate 12. The two flow rate adjustment components 14 are respectively located at the center points of the two arcs of the slot 13. The flow rate regulating component 14 includes a first rotating shaft 15 rotatably connected to the mounting plate 12. A housing 16 is fixedly connected to the first rotating shaft 15. Multiple notches 17 are provided on the side wall of the housing 16. Sliding rods 18 are slidably connected in each of the multiple notches 17. The multiple sliding rods 18 extend radially along the first rotating shaft 15 and are evenly distributed around the central axis of the first rotating shaft 15. A cover 19 is fixedly connected to the housing 16. A first connecting rod 20 passes through the cover 19. A connecting plate 21 is fixedly connected to one end of the first connecting rod 20 located inside the housing 16. A planar thread 22 is fixedly connected to the connecting plate 21. A first groove adapted to the planar thread 22 is provided on each of the multiple sliding rods 18. The first grooves on the multiple sliding rods 18 are engaged with the planar thread 22. By rotating the first connecting rod 20 and the planar thread 22, the multiple sliding rods 18 can be simultaneously driven to slide radially synchronously along their length. The end of the slide rod 18 away from the first rotating shaft 15 is fixedly connected to a hemispherical protrusion 23. When the slide rod 18 slides radially to the outermost end, the protrusion 23 can abut against and squeeze the wall of the delivery pipe 2 located in the slot 13. The mounting plate 12 is fixedly connected to a drive assembly 24 for driving one of the first rotating shafts 15 to rotate around its central axis. By driving the first rotating shaft 15 to rotate through the drive assembly 24, the protrusion 23 can be driven to rotate around the central axis of the first rotating shaft 15, thereby pushing the fluid in the delivery pipe 2. A linkage component 25 is installed between the two first rotating shafts 15, and the linkage component 25 can drive the other first rotating shaft 15 to rotate around its central axis as one of the first rotating shafts 15 rotates around its central axis.

[0027] One end of each of the two first rotating shafts 15 passes through the side wall of the mounting plate 12. The linkage assembly 25 includes two spur gears 26 that are respectively fixedly connected to the ends of the two first rotating shafts 15 away from the housing 16, and the two spur gears 26 mesh with each other.

[0028] The drive assembly 24 includes a support plate 27 fixedly connected to the mounting plate 12, and a motor 28 fixedly connected to the support plate 27. The output end of the motor 28 passes through the support plate 27 and is fixedly connected to one of the first rotating shafts 15.

[0029] The injection assembly 11 includes a piston block 29 slidably connected in the second cavity 7. The piston block 29 is sealed to the inner wall of the second cavity 7. A push rod 30 is fixedly connected to the piston block 29. The push rod 30 extends along the height direction of the second cavity 7. The end of the push rod 30 away from the piston block 29 passes through the heat preservation cover 4 upward. A first protective shell 31 is fixedly connected to the mounting plate 12. A first bevel gear 32 and a second bevel gear 33 meshing with the first bevel gear 32 are provided inside the first protective shell 31. The first bevel gear 32 is fixedly connected to a first rotating shaft 15 that is not connected to the output shaft of the motor 28. A second rotating shaft 34 fixedly connected to the second bevel gear 33 is rotatably connected to the side wall of the first protective shell 31. A screw 35 is fixedly connected to the second rotating shaft 34, and a nut 36 is threadedly connected to the screw 35. A second connecting rod 37 is fixedly connected to the side wall of the nut 36, and the end of the second connecting rod 37 away from the nut 36 is fixedly connected to the push rod 30.

[0030] It also includes a controller, the signal output terminal of which is electrically connected to the signal input terminal of the motor 28.

[0031] Working principle: The incubator 3 is divided into a first chamber 6 (containing nutrient solution) and a second chamber 7 (containing warm water) by a partition 5, and is connected to the delivery pipe 2 through a three-way valve 8. The input of nutrient solution or warm water can be switched by adjusting the three-way valve 8. During continuous nutrient solution infusion, the system can switch from nutrient solution to warm water at set intervals to flush the delivery pipe 2 and the nasoenteric tube, reducing the probability of blockage.

[0032] Each of the multiple slide rods 18 has a first groove adapted to the planar thread 22. The first grooves on the multiple slide rods 18 are engaged with the planar thread 22. By rotating the first connecting rod 20 and the planar thread 22, the multiple slide rods 18 can be driven to slide synchronously radially along their length. The two flow rate adjustment components 14 can cover most of the area of ​​the conveying pipe 2 in the S-shaped slot 13, so that the section of the conveying pipe 2 located in the slot 13 has a lower risk of blockage compared to the operation of a single flow rate adjustment component 14 in the prior art.

[0033] By using two spur gears 26 at the ends of the two first rotating shafts 15 away from the housing 16, the two spur gears 26 mesh with each other, and the motor 28 drives one of the first rotating shafts 15 to rotate, which in turn drives the other first rotating shaft 15 to rotate synchronously, causing the two sets of protrusions 23 to rotate and push the fluid. By adjusting the first connecting rods 20 and protrusions 23 of the two flow rate regulating components 14 so that they abut and squeeze the wall of the delivery pipe 2 in the slot 13, and the two sets of protrusions 23 have different tightness with the wall of the delivery pipe 2, the motor... During the clockwise rotation of the output shaft of 28, the first rotating shaft 15, housing 16, slide rod 18, and protrusion 23 are driven to rotate clockwise, which in turn drives the corresponding first rotating shaft 15, housing 16, slide rod 18, and protrusion 23 to rotate clockwise. Under the meshing action of the two spur gears 26, another set of first rotating shafts 15, housing 16, slide rod 18, and protrusion 23 are driven to rotate counterclockwise, causing the two sets of protrusions 23 to rotate alternately. This enables the nutrient solution in the delivery pipe 2 to flow at a differential speed, further reducing the risk of blockage in the delivery pipe 2.

[0034] The piston block 29 and the push rod 30 are slidably connected in the second cavity 7. The first bevel gear 32 is fixedly connected to the first rotating shaft 15, which is not connected to the output shaft of the motor 28. The second rotating shaft 34, which is fixedly connected to the second bevel gear 33, is rotatably connected to the side wall of the first protective shell 31. The second bevel gear 33 meshes with the first bevel gear 32. The screw 35 is fixedly connected to the second rotating shaft 34. The nut 36 is threadedly connected to the screw 35. The second connecting rod 37 is fixedly connected to the side wall of the nut 36. The end of the second connecting rod 37 away from the nut 36 is fixedly connected to the push rod 30. The controller controls the output shaft of motor 28 to rotate clockwise, which drives the corresponding first rotating shaft 15 and first bevel gear 32 to rotate clockwise. The first bevel gear 32 and the second bevel gear 33 drive the second bevel gear 33, the second rotating shaft 34 and the screw 35 to rotate counterclockwise. The nut 36 moves downward along the length of the screw 35, which drives the second connecting rod 37, the push rod 30 and the piston block 29 to move downward, pushing warm water into the second connecting pipe 10 and into the delivery pipe 2 through the three-way valve 8 to flush the pipe. Compared with the method of making the warm water in the delivery pipe 2 peristaltic by rotating the output shaft of motor 28 counterclockwise and using the flow rate regulating component 14, this method can increase the water pressure and make it easier to flush away the substances blocking the delivery pipe 2. Moreover, a single motor 28 can drive multiple components.

[0035] How to use: Step 1: Detachably fix the insulated box 3 to the support rod 1; Step 2: Open the heat preservation cover 4, inject an appropriate amount of enteral nutrition solution into the first cavity 6, and inject warm water into the second cavity 7; Step 3: Insert the delivery pipe 2 into the S-shaped slot 13 on the mounting plate 12; Step 4: Rotate the first connecting rod 20 counterclockwise, causing the connecting plate 21 and the planar thread 22 to rotate counterclockwise. The planar thread 22 engages with the first groove on the slide rod 18, pushing multiple slide rods 18 and protrusions 23 to slide radially away from the central axis of the first rotating shaft 15, so that the protrusions 23 extend radially and abut against the side wall of the conveying pipe 2 in the slot 13, and clamp and fix the conveying pipe 2. Step 5: Adjust the three-way valve 8 to connect the first connecting pipe 9 with the delivery pipe 2, and close the second connecting pipe 10 with the delivery pipe 2, so that the nutrient solution flows into the delivery pipe 2; Step Six: The controller controls the output shaft of the motor 28 to rotate counterclockwise, driving the corresponding first rotating shaft 15, housing 16, slide rod 18, and protrusion 23 to rotate counterclockwise. Under the meshing action of the two spur gears 26, another set of first rotating shafts 15, housing 16, slide rod 18, and protrusion 23 rotate clockwise, causing the two sets of protrusions 23 to rotate alternately, squeezing the delivery tube 2 and pushing the nutrient solution from the end of the delivery tube 2 near the incubator 3 to the end of the delivery tube 2 away from the incubator 3. The air in the delivery tube 2 is expelled under the push of the nutrient solution. Then, the end of the delivery tube 2 away from the incubator 3 is connected to the patient's nasoenteric tube. Step 7: When the set time is reached or the delivery pipe 2 is blocked, adjust the three-way valve 8 to connect the second connecting pipe 10 with the delivery pipe 2, and close the first connecting pipe 9 with the delivery pipe 2; Step 8: Rotate the first connecting rod 20 clockwise, causing the connecting plate 21 and the planar thread 22 to rotate clockwise. The planar thread 22 engages with the first groove on the slide rod 18, pushing multiple slide rods 18 and protrusions 23 to slide along the radial direction of the first rotating shaft 15 close to the central axis of the first rotating shaft 15. The protrusions 23 retract radially and disengage from the side wall of the conveying pipe 2 in the slot 13. Step 9: The controller controls the output shaft of the motor 28 to rotate clockwise, which drives the corresponding first rotating shaft 15 and first bevel gear 32 to rotate clockwise. The first bevel gear 32 and the second bevel gear 33 mesh, which drives the second bevel gear 33, the second rotating shaft 34 and the screw 35 to rotate counterclockwise. The nut 36 moves downward along the length of the screw 35, which drives the second connecting rod 37, the push rod 30 and the piston block 29 to move downward, pushing warm water into the second connecting pipe 10, and then into the conveying pipe 2 through the three-way valve 8 to rinse the conveying pipe 2. Step 10: After rinsing, repeat steps 4 to 6 to continue nutrient solution delivery.

[0036] Technical effect: Compared with existing technologies, by injecting warm water under high pressure into the delivery tube 2 within a set time during continuous infusion, the patient can effectively prevent and clear blockages in the delivery tube 2 and the nasoenteric tube, reducing the risk of blockage in the delivery tube 2.

[0037] The flow rate of the nutrient solution in the delivery pipe 2 is differentially adjusted by the two flow rate adjustment components 14, and the two flow rate adjustment components 14 can cover most of the area of ​​the delivery pipe 2 in the S-shaped groove 13, further reducing the risk of blockage of the delivery pipe 2.

[0038] The insulated box 3 has a certain heat preservation effect, maintaining the temperature of the nutrient solution, reducing the probability of the nutrient solution cooling and solidifying, and further reducing the risk of blockage of the delivery pipe 2.

[0039] In this embodiment, a handle 38 is fixedly connected to the end of the first connecting rod 20 away from the connecting plate 21.

[0040] Technical effect: By fixing the handle 38 to the end of the first connecting rod 20 away from the connecting plate 21, it is convenient for the user to hold and rotate the first connecting rod 20.

[0041] In this embodiment: a limiting block 39 is fixedly connected to the conveying pipe 2, and a retaining ring 40 adapted to the limiting block 39 is fixedly connected to the mounting plate 12. The limiting block 39 is snap-fit ​​fixedly connected inside the retaining ring 40.

[0042] Technical effect: By fixing a limiting block 39 to the conveying pipe 2 and a retaining ring 40 adapted to the limiting block 39 to the mounting plate 12, the limiting block 39 is fixedly connected to the retaining ring 40 in a snap-fit ​​manner. This enhances the stability of the connection between the conveying pipe 2 and the mounting plate 12, and reduces the probability of uneven flow velocity or blockage caused by pipe movement.

[0043] In this embodiment: a second groove 41 is provided on the side wall of the heat preservation box 3, and an electric heating wire 42 is fixedly installed in the second groove 41. A temperature sensor 43 is fixedly connected inside the heat preservation cover 4. The signal output terminal of the temperature sensor 43 is electrically connected to the signal input terminal of the controller, and the signal output terminal of the controller is electrically connected to the signal input terminal of the electric heating wire 42.

[0044] Technical effect: By opening a second groove 41 on the side wall of the heat preservation box 3, an electric heating wire 42 is fixedly installed in the second groove 41, and a temperature sensor 43 is fixedly connected in the heat preservation cover 4.

[0045] The signal output terminal of the temperature sensor 43 transmits the detected temperature to the signal input terminal of the controller. The controller controls the heating wire 42 to heat the nutrient solution in the first cavity 6 and the warm water in the second cavity 7, so that the nutrient solution in the first cavity 6 and the warm water in the second cavity 7 are maintained at a set temperature (e.g., 37 degrees Celsius).

[0046] Maintaining the nutrient solution and warm water at a suitable temperature reduces the probability of the nutrient solution solidifying or deteriorating due to cooling, further reducing the risk of blockage in delivery tube 2.
