Description

Technical Field

[0001] The present invention relates to the field of nutritional assistance, and in particular to an intestinal nutritional assistance system. Background Art

[0002] For people with eating disorders, such as Crohn's disease, a feeding tube is inserted to replace the feeding function and maintain nutritional function. Specifically, a syringe is usually used to draw out fluids such as nutrient solution, which is then connected to the exposed part of the feeding tube. The exposed part may be in the nose or abdomen. The fluid in the syringe is then pushed into the feeding tube to achieve nutritional supply. Finally, water is flushed into the feeding tube through the syringe using a pulse technique to prevent blockage.

[0003] However, due to the limited capacity of the syringe and the need for manual operation, it usually takes a lot of time for patients to eat; for some patients with chronic diseases, the need to use a feeding tube for a long time will delay the patients from doing other things; since some patients are in good physical condition and like to go out, eating outdoors becomes a big problem and is very inconvenient to carry. Summary of the Invention

[0004] The present invention aims to provide an intestinal nutrition auxiliary system suitable for eating outdoors.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an intestinal nutrition auxiliary system, including a backpack, a fixed plate is provided in the backpack, a driving member is fixed on the fixed plate, the output shaft end of the driving member is connected to a conveying wheel, and a plurality of protrusions are provided on the conveying wheel; a nutrition bottle is detachably connected to the fixed plate, the bottle mouth of the nutrition bottle faces downward and is connected to a delivery tube, the delivery tube bypasses the delivery wheel and passes upward out of the backpack and is connected to the nutrition tube on the patient, and the protrusions on the delivery wheel are used to push the nutrient solution in the delivery tube into the nutrition tube.

[0006] The beneficial effects of this program are: 1. Secure the nutrient bottle containing the nutrient solution in a backpack so that the patient can carry the nutrient bottle with them when traveling and eat while walking. Since nutrient solution is usually less fluid, it usually requires the use of a syringe, which is inconvenient for patients to use when traveling. In this solution, a delivery wheel replaces the syringe's propulsion function. The protrusions on the delivery wheel gradually push the nutrient solution in the delivery tube forward. 2. Compared with using various pumps to push the nutrient solution, on the one hand, most of the nutrient solution is viscous, and the pumping effect of this type of nutrient solution is poor. The nutrient solution is easy to remain in the pump and cause blockage in the pump; on the other hand, the delivery tube is usually disposable and needs to be replaced frequently. When connected to the pump, not only does the delivery tube need to be divided into two parts for connection to the pump, but it also needs to be plugged and unplugged frequently to replace the delivery tube, which is very troublesome; therefore, this solution uses a delivery wheel instead of a pump, which is not only suitable for viscous nutrient solution, but also does not need to disconnect the delivery tube, making it easy to replace, especially suitable for outdoor feeding.

[0007] 3. Although the feeding time of this solution is not as short as that of the syringe, it has the advantage of not requiring human intervention, being able to feed automatically, lasting for a long time, and being convenient for feeding outdoors.

[0008] Furthermore, the backpack includes a shoulder strap, and the upper portion of the delivery tube is detachably connected to the shoulder portion of the shoulder strap after passing through the backpack, which is suitable for nasogastric feeding.

[0009] Furthermore, a water bottle with its mouth facing downward is detachably connected to the fixed plate. The delivery pipe is a three-way pipe comprising a main pipe, a first branch pipe, and a second branch pipe. The main pipe is connected to the nutrient pipe, the first branch pipe is connected to the lower end of the nutrient bottle, and the second branch pipe is connected to the lower end of the water bottle. The angle between the first branch pipe and the second branch pipe is less than 90 degrees. The delivery pipe and the nutrient pipe are flushed by water in the water bottle. The angle between the first branch pipe and the second branch pipe is less than 90 degrees, making it easier for nutrient solution in the first branch pipe to enter the main pipe. If some nutrient solution in the first branch pipe enters the second branch pipe, the narrow angle will prevent the nutrient solution from continuing to enter the second branch pipe and instead continue to flow into the main pipe.

[0010] Furthermore, the second branch is equipped with a flow regulator for adjusting the flow rate within the tube. The flow regulator is fixed in a regulating hole on the side of the backpack for manual adjustment. This allows the patient to actively control the flushing of the water pipe, such as before and after meals or every four hours according to the usage specifications.

[0011] Furthermore, a pulse plate is horizontally provided in the water bottle, an elastic member is vertically provided between the lower side of the pulse plate and the inner wall of the water bottle, and a one-way valve unit is provided on the pulse plate, which is used to limit the flow rate of liquid on the lower side of the pulse plate when it flows upward.

[0012] Furthermore, a one-way hole is provided on the pulse plate, and the one-way valve unit includes a support frame and a plurality of fan-shaped flexible baffles on the lower side of the support frame. The support frame is fixed in the one-way hole, and the arc-shaped edge of the flexible baffle is fixed to the edge of the one-way hole. In the initial state, several flexible baffles are attached to the underside of the support frame, and liquid can only pass through the gaps between the flexible baffles; When the pressure above the flexible baffle increases, the flexible baffle flips downward and the flow rate of the one-way hole increases.

[0013] Furthermore, the water bottle includes an upper bottle and a lower bottle which are threadedly connected. The lower end of the lower bottle is provided with a bottle mouth, and the pulse plate and the elastic member are arranged in the lower bottle.

[0014] Furthermore, a one-way hole is arranged at the center of the pulse plate, and the support frame includes several guide plates arranged circumferentially. The length direction of the guide plate is the radial direction of the one-way hole. The guide plate is inclined relative to the horizontal plane. The water flow passing through the guide plate can form a vortex or has a tendency to form a vortex.

[0015] This solution also has the following effects: 1. During the flushing process of the feeding tube, it is usually required to flush with a pulse effect. However, it is difficult to achieve the above effect after the syringe is eliminated. Therefore, in this solution, a special water bottle is used, which is divided into two parts, upper and lower. A pulse plate is set in the lower bottle. The pulse plate oscillates up and down as the patient moves. Since there is an elastic member between the pulse plate and the lower bottle, the oscillation amplitude of the pulse plate lags behind the water bottle, so the pulse plate moves up and down relatively in the water bottle; when the pulse plate moves upward, the water pressure from the upper part pushes open the flexible baffle and enters the lower part. At the same time, the water flow passing through the guide plate forms a vortex, accelerating the flow rate of the water at the center, thereby speeding up the speed of the water entering the lower part; when the pulse plate moves downward, the water pressure from the lower part pushes the flexible baffle to recover and blocks most of the gap between the guide plates. The pulse plate continues to move downward and presses the water from the lower part into the first branch pipe, thereby forming a pulse effect and enhancing the cleaning effect.

[0016] 2. The upper and lower bottles are connected by threads, so they can be removed for regular cleaning of the pulse plate.

[0017] 3. Since no pump is used or height difference is utilized, in order to ensure that the water in the water bottle can be delivered to the nutrition tube, this solution uses a pulse plate to replace the pumping effect, and sufficient water in the water bottle is required to generate thrust.

[0018] 4. To simultaneously deliver and clean the nutrient solution, this solution uses a three-way pipe. First, the delivery wheel pushes the nutrient solution into the patient's body. As the nutrient solution in the nutrient bottle gradually decreases, the flow regulator is opened to allow a small amount of water to flow into the main pipe. This mixing of the nutrient solution with the water enhances its fluidity, reducing the risk of pipe blockage. At this point, the fluidity of the nutrient solution in the main pipe is stronger than that in the first branch pipe. As the nutrient solution in the nutrient bottle continues to decrease, the nutrient solution in the first branch pipe also gradually decreases. The delivery wheel can no longer push the nutrient solution forward. The flow regulator is adjusted to maximize the flow. Under the action of the pulse plate, the water flow continuously impacts the nutrient solution in the pipe, thereby achieving a cleaning effect. Since the nutrient solution in the main pipe has stronger fluidity than the nutrient solution in the first branch pipe, the water flow will preferentially flow to the main pipe that is more easily conducted at the tee position, thereby cleaning the main pipe and the nutrient pipe. The nutrient in the first branch pipe does not need to be flushed and can be discarded and replaced with the tee pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is further described in detail through specific implementation methods: The figure marks in the drawings of the specification include: backpack 1, shoulder strap 11, fixing plate 12, horizontal plate 13, water bottle 2, upper bottle 21, lower bottle 22, pulse plate 23, one-way hole 24, guide plate 25, connecting column 26, flexible baffle 27, elastic member 28, air intake bolt 29, air guide hole 20, flow regulator 3, first fixing belt 41, first annular member 42, nutrient bottle 5, pipeline holder 6, conveying wheel 7, second fixing belt 81, second annular member 82, main pipe 91, first branch pipe 92, second branch pipe 93.

[0021] Example The embodiment is basically as follows Figures 1-6 As shown: an intestinal nutrition auxiliary system, including Figure 1 The backpack 1 shown, Figure 2 As shown, a fixing plate 12 is bolted inside the backpack 1, and a horizontal plate 13 is welded to the lower end of the fixing plate 12. The horizontal plate 13 is used to support the backpack on a flat surface such as a desktop or the ground; The flow regulator 3, the second fixing assembly, the pipe holder 6 and the driving member, and the first fixing assembly are bolted to the fixing plate 12 from left to right. The nutrition bottle 5 with the bottle mouth facing downward is fixed to the first fixing assembly, and the water bottle 2 with the bottle mouth facing downward is fixed to the second fixing assembly. The driving member is embedded in the fixed plate 12 (not shown in the figure). In this embodiment, the driving member is a servo motor. The output shaft of the driving member is perpendicular to the fixed plate 12. The end of the output shaft of the driving member is bolted to the conveying wheel 7. The rotating surface of the conveying wheel 7 is parallel to the fixed plate 12. The conveying wheel 7 has a plurality of arc-shaped protrusions integrally formed around the circumference. The first fixing assembly includes a first fixing belt 41 and a first annular member 42. The first annular member 42 is arranged horizontally and is integrally formed with the fixing plate 12. The mouth of the nutrition bottle 5 faces downward and passes through the first annular member 42, so that the nutrition bottle 5 is supported on the first annular member 42. The first fixing belt 41 is bolted to the fixing plate 12. The first fixing belt 41 is used to tie the body of the nutrition bottle 5 to prevent the nutrition bottle 5 from tipping over. Similarly, the second fixing assembly includes a second fixing belt 81 and a second ring member 82. The second ring member 82 is arranged horizontally and is integrally formed with the fixing plate 12. The bottle mouth of the water bottle 2 faces downward and passes through the second ring member 82, so that the water bottle 2 is supported on the second ring member 82. The second fixing belt 81 is bolted to the fixing plate 12. The second fixing belt 81 is used to tie the bottle body of the water bottle 2 to prevent the water bottle 2 from tipping over. The backpack 1 includes a shoulder strap 11 with a strap. The backpack 1 also includes a delivery pipe, which is a three-way pipe. The three-way pipe includes a main pipe 91, a first branch pipe 92, and a second branch pipe 93. The three pipes are connected at the three-way position. The angle between the first branch pipe 92 and the second branch pipe 93 is less than 90 degrees. The first branch pipe 92 is aligned with the main pipe 91. In this embodiment, the three pipes are described from the three-way position toward the end.

[0022] The main pipe 91 passes upward out of the backpack 1 and moves forward along the shoulder strap 11. The strap on the shoulder strap 11 secures the main pipe 91. The main pipe 91 continues forward until it is connected to the patient's nutrition tube. The joint of the nutrition tube is set in the existing technology. In this embodiment, the joint between the main pipe 91 and the nutrition tube adopts a plug-in design. The pipe holder 6 has two vertical pipe grooves for clamping and fixing the first branch pipe 92. The first branch pipe 92 is first clamped in one of the clamping grooves, then extends downward and bypasses the conveying wheel 7, and then extends upward and clamps in the other clamping groove, thereby ensuring that the first branch pipe 92 between the two clamping grooves maintains a certain tension, so that when the conveying wheel 7 rotates, the nutrient solution in the pipe can be pushed forward through the protrusion, thereby achieving the effect of peristaltic advancement. Figure 2 In the figure, the direction of rotation of the conveying wheel 7 is clockwise, and finally the end of the first branch pipe 92 is connected to the nutrition bottle 5. The connection method here is the existing technology: the bottle mouth of the nutrition bottle 5 is usually covered with a rubber sleeve, and the end of the first branch pipe 92 is sharp to pierce the rubber sleeve. The side of the first branch pipe 92 is provided with a port for exhaust. The existing technology will not be described in detail here.

[0023] The second branch pipe 93 is provided with a flow regulator 3, which is used to adjust the flow rate within the pipe. The flow regulator 3 is a common device used to adjust the flow rate during intravenous infusion in the prior art, and the flow rate can be adjusted by sliding a roller on it. An adjustment hole is provided on the side of the backpack 1. The fabric of the backpack 1 near the adjustment hole is bonded to an iron plate, thereby securing the flow regulator 3 within the adjustment hole. This allows the patient to manually adjust the flow regulator 3 by reaching behind with their backhand. The second branch pipe 93 first approaches the side of the backpack 1, positioning the flow regulator 3 within the adjustment hole, and then continues downward until it connects with the bottle opening at the lower end of the water bottle 2. like Figure 3 As shown, the water bottle 2 includes an upper bottle 21 and a lower bottle 22. The inner side of the lower end of the upper bottle 21 is threadedly connected to the outer side of the lower bottle 22. The lower end of the lower bottle 22 is provided with a bottle mouth. The inner side of the lower bottle 22 is provided with a pulse plate 23 and an elastic member 28. The elastic member 28 is a rubber spring with an inner diameter larger than the inner diameter of the bottle mouth. The lower end of the rubber spring is connected to the inner bottom of the lower bottle 22, and the upper end of the rubber spring is connected to the lower surface of the pulse plate 23. The rubber springs are connected by flange sleeves. This is a prior art and will not be described in detail. Since the water bottle 2 is placed in the backpack 1, an air inlet must be reserved to ensure that water can flow out and to prevent water from spilling out of the air inlet. Therefore, in this solution, an air inlet is provided at the upper end of the upper bottle 21. The inner side of the air inlet is provided with an internal thread. The inner thread of the air inlet is connected to an air inlet bolt 29. The air inlet bolt 29 has an air guide hole 20 formed therein. The air guide hole 20 connects the side of the air inlet bolt 29 and the inner side of the upper bottle 21.

[0024] The pulse plate 23 is arranged horizontally, and a one-way hole 24 is provided on the pulse plate 23. A one-way valve unit is provided in the one-way hole 24. The one-way valve unit is used to limit the flow of the liquid under the pulse plate 23 when it flows upward. The one-way valve unit includes a support frame and four fan-shaped flexible baffles 27 on the lower side of the support frame. Figure 4 As shown, the support frame is fixed in the one-way hole 24. The support frame includes a connecting column 26 and six circumferentially arranged guide plates 25. The connecting column 26 is set at the center of the guide hole and is integrally formed with the end of the guide plate 25. The length direction of the guide plate 25 is the radial direction of the one-way hole 24. The other end of the guide plate 25 is integrally formed with the side wall of the one-way hole 24. The guide plate 25 is set at an inclination of 70° relative to the horizontal plane. The water flow passing through the guide plate 25 can form a vortex or has a tendency to form a vortex.

[0025] like Figure 6 As shown, the flexible baffle 27 is made of rubber material, the curved edge of the flexible baffle 27 and the top of the rubber spring are integrally formed, and the rubber spring and the pulse plate 23 clamp the flexible baffle 27, thereby fixing the curved edge of the flexible baffle 27 to the lower surface of the pulse plate 23 at the edge of the one-way hole 24; Figure 5As shown, the flexible baffles 27 are filled with small dots, and the gaps between adjacent flexible baffles 27 are staggered with the guide plates 25, so that the flexible baffles are closed to block the guide plates 25 and shield their guide effect.

[0026] In the initial state, the flexible baffles 27 are attached to the lower side of the support frame, and the liquid can only pass through the gaps between the flexible baffles 27; When the pressure above the flexible baffle 27 increases, the flexible baffle 27 flips downward, and the flow rate of the one-way hole 24 increases.

[0027] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
