Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical assistive device technology, specifically a liquid feeding device for patients after esophageal surgery. Background Technology
[0002] Esophageal surgery is a general term for surgical techniques that repair or remove diseased esophageal tissue to treat various esophageal diseases. Its core lies in intervening in the anatomical structure and functional abnormalities of the esophagus, covering a variety of surgical procedures from simple repair to complex reconstruction. Drinking liquid feeding devices are medical devices designed for patients who cannot eat independently or have difficulty swallowing. By controlling the supply of liquid food, they meet their nutritional needs while reducing the pain and inconvenience of eating. In the early postoperative period (usually within 1-2 weeks after surgery), most patients need to use a nasogastric tube for nutritional support and cannot drink liquid food orally.
[0003] However, most of the liquid feeding devices currently in use provide nutrition to patients through a syringe and a nasogastric tube. However, the syringe needs to be held by medical staff or family members for a long time during use, which can easily lead to hand fatigue and make it difficult to accurately control the speed of liquid feeding, resulting in inconvenience in liquid feeding.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a liquid feeding device for patients after esophageal surgery. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention provides a liquid feeding device for patients after esophageal surgery, thus solving the problem of inconvenient liquid feeding in the prior art.
[0006] A liquid feeding device for post-esophageal surgery patients includes a main tube, a supporting disc that is slidably positioned inside the main tube, a silicone bag fixedly mounted on the bottom side inside the main tube, a liquid feeding bag supported by the supporting disc in the main tube, a nasogastric tube fixedly mounted on the liquid feeding bag, and an air pump fixedly mounted on the main tube. The device also includes: an air inflation mechanism located at the bottom of the main tube for moving the supporting disc up and down within the main tube; a protective mechanism located on the air inflation mechanism for protection during feeding from the liquid feeding bag; and a connecting mechanism located on the main tube for supporting and connecting the main tube.
[0007] Preferably, the inflation mechanism includes a lower base fixedly disposed at the bottom of the main body cylinder, and a vent pipe is fixedly disposed on the side wall of the lower base; the lower base is connected to the inflation pump through the vent pipe.
[0008] Preferably, the inflation mechanism further includes a support ring fixedly disposed on the top of the lower base, and the silicone bag is sealed and fixedly disposed on the top of the lower base through the support ring; and the interior of the silicone bag is connected to the air vent.
[0009] Preferably, the protective mechanism includes a vent pipe fixedly disposed on the side wall of the support ring, and a protective film is fixedly disposed at the middle position inside the vent pipe, and a plurality of pre-cut marks are integrally formed on the protective film.
[0010] Preferably, the protective mechanism further includes vent holes at both ends of the vent pipe, and the sidewall of the vent pipe is fixedly provided with sealing threads.
[0011] Preferably, the connecting mechanism includes a connecting thread fixedly disposed on the top of the main body cylinder, and the main body cylinder is screwed with an upper cover through the connecting thread, and the upper cover has a connecting hole.
[0012] Preferably, the connecting mechanism further includes an upper top plate fixedly disposed on the top of the liquid food bag, a connecting pipe fixedly disposed on the upper top plate, and a lower bottom plate fixedly disposed on the bottom of the liquid food bag; and the connecting pipe can penetrate through the interior of the connecting hole.
[0013] Preferably, the connecting mechanism further includes several limiting grooves formed on the inner wall of the main body cylinder, and several limiting balls are fixedly provided on the side wall of the supporting disc; the supporting disc is slidably disposed inside the main body cylinder by the several limiting grooves and limiting balls.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This invention features a main tube, allowing the liquid feeding bag to slide smoothly and be supported by a support disc inside the main tube. A support ring on the bottom side of the main tube seals and fixes the silicone bag to the lower base. When the patient needs to be fed liquid food, an air pump inflates the silicone bag through a ventilator, causing it to expand slowly. This expansion pushes the support disc upwards, pressing the liquid feeding bag against the bottom of the main tube. The liquid food inside the bag can then be slowly introduced into the patient's body through a nasogastric tube. Because the inflation speed of the air pump can be precisely controlled, the rising speed of the support disc and the compression speed of the liquid feeding bag can be precisely controlled, thus improving the accuracy and convenience of the liquid feeding placement for the patient.
[0016] 2. This invention features a vent pipe screwed into the side wall of the support ring, which provides protection against rupture by a protective film inside the vent pipe. When the feeding bag becomes clogged, the gas inside the silicone bag increases in pressure. This gas then impacts the protective film, which has an integrally formed pre-cut groove that is easily ruptured under gas pressure. When the pre-cut groove ruptures, the gas inside the silicone bag is released through the vent pipe, while the silicone bag remains in place. This prevents the liquid food inside the bag from continuously impacting the clogged area and also prevents backflow, thus improving the safety of the liquid food position in the bag.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0028] Example 1:
[0029] As attached Figure 1 To be continued Figure 8 As shown:
[0030] This invention provides a liquid feeding device for patients after esophageal surgery, comprising a main body cylinder 1, a supporting disc 12 slidably disposed inside the main body cylinder 1, a silicone bag 15 fixedly disposed on the bottom side inside the main body cylinder 1, a liquid feeding bag 10 supported by the supporting disc 12 on the main body cylinder 1, a nasogastric tube 4 fixedly disposed on the liquid feeding bag 10, and an air pump 7 fixedly disposed on the main body cylinder 1. It also includes: an air inflation mechanism disposed at the bottom of the main body cylinder 1 for pushing the supporting disc 12 to move up and down within the main body cylinder 1; a protective mechanism disposed on the air inflation mechanism for protection during feeding of the liquid feeding bag 10; and a connecting mechanism disposed on the main body cylinder 1 for supporting and connecting the main body cylinder 1.
[0031] By providing a main body cylinder 1, the liquid food bag 10 can be easily slidably connected to the inside of the main body cylinder 1 via the support disc 12 inside the main body cylinder 1. The silicone bag 15 is sealed and fixed to the lower base 5 on the bottom side of the inside of the main body cylinder 1 via the support ring 21. When the patient needs to be fed liquid food, the air pump 7 can inflate the silicone bag 15 through the air tube 6, causing the silicone bag 15 to expand slowly. This pushes the support disc 12 to rise and squeeze the liquid food bag 10 to the bottom of the main body cylinder 1, so that the liquid food inside the liquid food bag 10 can be slowly introduced into the patient's body through the nasogastric tube 4 for feeding. Since the inflation speed of the air pump 7 can be precisely controlled, the rising speed of the support disc 12 and the squeezing speed of the liquid food bag 10 can be precisely controlled, thereby improving the accuracy and convenience of the liquid food position for the patient.
[0032] Meanwhile, a vent pipe 16 is screwed onto the side wall of the support ring 21, so that the protective film 18 set inside the vent pipe 16 can be protected against rupture. When the feeding bag 10 is blocked, the gas in the silicone bag 15 increases and the pressure increases. At this time, the gas in the silicone bag 15 will also impact the protective film 18. The pre-cut mark 19 integrally formed on the protective film 18 is easy to break when it is squeezed by gas. Thus, when the pre-cut mark 19 breaks, the gas in the silicone bag 15 will be discharged from the vent pipe 16. At the same time, the silicone bag 15 remains unchanged, preventing the liquid food in the liquid food bag 10 from continuously impacting the blockage. It can also prevent the liquid food bag 10 from back-suction, thereby improving the safety of the liquid food position of the liquid food bag 10.
[0033] Secondly, when feeding liquid food through the nasogastric tube 4, medical staff or family members should supervise the feeding and pay close attention to the state of the liquid food inside the nasogastric tube 4. When the protective film 18 breaks through the pre-break mark 19, the liquid food inside the nasogastric tube 4 will be in a static state, and care should be provided in time to avoid harm to the patient.
[0034] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The inflation mechanism includes a silicone bag 15, an air tube 6, and an air pump 7;
[0035] By fixing a lower base 5 to the bottom of the main body cylinder 1, the main body cylinder 1 can be supported by the lower base 5 during use. Inside the main body cylinder 1, at the top of the lower base 5, a support ring 21 is fixedly connected. The lower base 5 is sealed to a silicone bag 15 through the support ring 21. When the support disc 12 needs to be adjusted to rise or fall inside the main body cylinder 1, the silicone bag 15 can be inflated to push the support disc 12 to rise. When the support disc 12 needs to be lowered, the silicone bag 15 can be slowly deflated to allow the support disc 12 to be adjusted to fall inside the main body cylinder 1, thereby controlling the rise and fall of the support disc 12.
[0036] Meanwhile, a vent pipe 6 is fixedly connected to the side wall of the lower base 5, which connects the vent pipe 6 to the silicone bag 15. The air pump 7 can also be connected to the silicone bag 15 through the vent pipe 6, so that when the silicone bag 15 needs to be inflated or deflated, the air pump 7 can make precise control and adjustment, thereby achieving the purpose of precise control and adjustment of the rise and fall of the support disc 12. The silicone bag 15 expands when inflated, driving the support disc 12 to rise. The inflation speed is controllable, so as to facilitate the precise control of the rising speed of the support disc 12.
[0037] Secondly, the silicone bag 15 is made of food-grade silicone, which has the advantages of excellent elasticity, being able to recover its original shape under pressure, high tear strength, wide temperature resistance range (-50℃~250℃), good biocompatibility, and being able to directly contact the skin and food.
[0038] Example 2:
[0039] refer to Figure 3 , Figure 6 and Figure 8 The protective mechanism includes a vent pipe 16, a protective membrane 18, and a vent 20;
[0040] A leak pipe 16 is screwed onto the side wall of the support ring 21, and a sealing thread is fixedly connected to the side wall of the leak pipe 16. This makes it easy for the leak pipe 16 to be sealed to the side wall of the support ring 21 through the sealing thread, and also makes it easy for the leak pipe 16 to be easily replaced and used through the sealing thread. This makes it easy for medical staff to replace the leak pipe 16 with one that can withstand different pressures according to the patient's usage needs.
[0041] Meanwhile, a protective film 18 is fixedly connected to the middle position inside the vent pipe 16, and a pre-cut mark 19 is integrally formed on the protective film 18. This allows the silicone bag 15 to push the support disc 12 upward when it is inflated and the support disc 12 squeezes the liquid food bag 10. If there is a blockage in the flow of liquid food inside the liquid food bag 10, the silicone bag 15 will have difficulty pushing the support disc 12 upward. The gas inside the silicone bag 15 will break through the protective film 18 and be released from the vent pipe 6. This avoids excessive pushing of the support disc 12 upward, which could cause serious blockage of liquid food inside the liquid food bag 10 or other accidents. The pre-cut mark 19 integrally formed on the protective film 18 also facilitates the rapid rupture of the protective film 18 when it is under pressure.
[0042] Secondly, ventilation holes 20 are provided at both ends of the vent pipe 16, so that the vent pipe 16 is connected to the inside of the silicone bag 15 through the ventilation holes 20 at both ends, so that when the silicone bag 15 is deflating, it can be discharged through the two ventilation holes 20.
[0043] Example 3:
[0044] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism includes an upper cover 2, an upper plate 13, a limiting slide groove 11, and a limiting ball 17;
[0045] By fixing an upper cover 2 to the top of the main body tube 1 and fixing a connecting thread 9 to the top of the main body tube 1, the upper cover 2 can be easily screwed onto the main body tube 1 through the connecting thread 9, so that the upper cover 2 can be easily connected and supported at the top of the main body tube 1. A connecting hole 8 is provided on the upper cover 2, so that the connecting tube 3 at the top of the liquid feeding bag 10 can be leaked out from the connecting hole 8 on the upper cover 2, thereby facilitating the connection of the connecting tube 3 to the nasogastric tube 4.
[0046] Meanwhile, an upper top plate 13 is fixedly connected to the top of the liquid food bag 10, allowing the liquid food bag 10 to be easily connected to the connecting tube 3 via the upper top plate 13. A lower bottom plate 14 is fixedly connected to the bottom of the liquid food bag 10, allowing the lower bottom plate 14 to easily support the liquid food bag 10. Both the upper top plate 13 and the lower bottom plate 14 are made of rigid materials, while the liquid food bag 10 is made of soft material. This allows the liquid food bag 10 to be filled with liquid food during use, and the liquid food bag 10 can be connected to the connecting tube 3 via the lower bottom plate 13. 4. Stable placement on the support disc 12, causing the silicone bag 15 to expand. When the support disc 12 is pushed, the liquid food bag 10 will be squeezed because the upper top plate 13 is attached to the bottom of the upper top cover 2 and the lower bottom plate 14 is attached to the top of the support disc 12. This allows the liquid food loaded inside the liquid food bag 10 to be discharged through the connecting tube 3 and finally guided into the patient's body through the nasogastric tube 4. The connecting tube 3 can be connected to the nasogastric tube 4 through the inside of the connecting hole 8, located above the upper top cover 2.
[0047] Secondly, several limiting grooves 11 are provided on the inner wall of the main body cylinder 1, and several limiting balls 17 are rolledly connected to the side wall of the support disc 12. The limiting grooves 11 and the limiting balls 17 are mutually limiting and sliding, so that when the support disc 12 is pushed by the silicone bag 15 during use, it can slide upward in a limited manner by the limiting grooves 11 and the limiting balls 17. When the silicone bag 15 is deflated, the support disc 12 can slide up and down in a limited manner by the limiting grooves 11 and the limiting balls 17. This makes it easy for the support disc 12 to rise and fall stably and be adjusted for use.
[0048] Working principle: A lower base 5 is fixedly connected to the bottom of the main body cylinder 1, allowing the main body cylinder 1 to be supported during use. A support ring 21 is fixedly connected to the top of the lower base 5 inside the main body cylinder 1. A silicone bag 15 is sealed to the lower base 5 via the support ring 21. When the support disc 12 needs to be adjusted upwards or downwards inside the main body cylinder 1, the silicone bag 15 inflates to push the support disc 12 upwards. When the support disc 12 needs to be lowered, the silicone bag 15 slowly deflates, allowing the support disc to descend. 12 is adjusted downwards inside the main body cylinder 1 to control the rise and fall of the support disc 12. Simultaneously, a protective film 18 is fixedly connected to the middle position inside the vent pipe 16, and a pre-cut groove 19 is integrally formed on the protective film 18. This allows the silicone bag 15 to push the support disc 12 upwards when it inflates. When the support disc 12 squeezes the liquid food bag 10, if there is a blockage in the flow of liquid food inside the liquid food bag 10, the silicone bag 15 will have difficulty pushing the support disc 12 upwards. The gas inside the silicone bag 15 will then break through the protective film 18 and escape through the vent pipe 16. The trachea 6 is vented to prevent excessive upward movement of the support disc 12, which could cause severe blockage of the liquid food in the liquid food bag 10 or other accidents. The protective film 18 has an integrally formed pre-cut groove 19 to facilitate rapid rupture of the protective film 18 under pressure. A top plate 13 is fixedly connected to the top of the liquid food bag 10, allowing for easy connection of the connecting tube 3. A bottom plate 14 is fixedly connected to the bottom of the liquid food bag 10, providing support for the bag. The top plate 13 and the bottom plate 14 are both made of rigid materials, while the liquid feeding bag 10 is made of soft material. This allows the liquid feeding bag 10 to be filled with liquid food during use. When the liquid feeding bag 10 is stably placed on the support disc 12 through the bottom plate 14, the silicone bag 15 expands. When the support disc 12 is pushed, the liquid feeding bag 10 will be squeezed because the top plate 13 is attached to the bottom of the top cover 2 and the bottom plate 14 is attached to the top of the support disc 12. This allows the liquid food filled inside the liquid feeding bag 10 to be discharged through the connecting tube 3 and finally guided into the patient's body through the nasogastric tube 4.
