Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary appliances, in particular to a device for drinking liquid food for patients after esophageal surgery. Background Art

[0002] Esophageal surgery is a general term for surgical techniques that repair or remove esophageal lesions to treat various esophageal diseases. Its core focus is on intervening in the anatomical structure and functional abnormalities of the esophagus, encompassing a variety of procedures from simple repair to complex reconstruction. Liquid feeding devices are medical devices designed specifically for patients who are unable to eat independently or have difficulty swallowing. By controlling the supply of liquid food, they meet their nutritional needs while alleviating the pain and inconvenience of eating. In the early postoperative period (usually within 1-2 weeks after surgery), most patients require a nasogastric feeding tube for nutritional support and cannot drink liquid food orally. However, the liquid feeding devices currently used mostly provide nutrition to patients through a syringe combined with a nasogastric tube. However, during the use of the syringe, medical staff or family members need to hold it in their hands for a long time, which can easily cause hand fatigue of the medical staff or family members, and it is difficult to accurately control the speed of liquid feeding, resulting in inconvenience in liquid feeding.

[0003] Therefore, those skilled in the art have proposed a device for drinking liquid food for patients after esophageal surgery to solve the problems raised in the background art. Summary of the Invention

The device also includes: an inflation mechanism, which is provided at the bottom of the main body tube 1 and is used to push the support disc 12 to move up and down in the main body tube 1; a protective mechanism, which is provided on the inflation mechanism and is used to protect the liquid food bag 10 during feeding; and a connecting mechanism, which is provided on the main body tube 1 and is used to support and connect the main body tube 1; By providing the main body tube 1, the liquid food bag 10 can be easily supported and slidably connected to the inside of the main body tube 1 through the support disc 12 inside the main body tube 1, and the silicone bag 15 is sealed and fixedly connected to the lower base 5 through the support ring 21 on the inner bottom side of the main body tube 1. When the patient needs to feed liquid food, the air pump 7 can inflate the inside of the silicone bag 15 through the ventilation tube 6, causing the silicone bag 15 to slowly expand, thereby pushing the support disc 12 to rise and squeeze the liquid food bag 10 to the bottom of the main body tube 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 is easy to accurately control, the purpose of accurately controlling the rising speed of the support disc 12 and the squeezing speed of the liquid food bag 10 can be achieved, thereby improving the accuracy and convenience of the patient's liquid food position; At the same time, an air leakage pipe 16 is screwed and connected to the side wall of the support ring 21, so that the protective film 18 provided in the air leakage pipe 16 can be protected from rupture. When the liquid food bag 10 is blocked during feeding, the gas in the silica gel bag 15 increases and the pressure increases. At this time, the gas in the silica gel bag 15 will also impact the protective film 18, and the pre-broken mark 19 integrally formed on the protective film 18 is easy to rupture when squeezed by the gas. Therefore, when the pre-broken mark 19 ruptures, the gas in the silica gel bag 15 will be discharged from the air leakage pipe 16, and the silica gel bag 15 will remain in its original shape, preventing the liquid food in the liquid food bag 10 from continuously impacting the blockage, and also preventing the liquid food bag 10 from having a back-suction problem, thereby improving the safety of the liquid food position of the liquid food bag 10; Secondly, when the nasogastric tube 4 is used for liquid feeding, medical staff or the patient's family should be on duty and pay attention to the state of the liquid food in the nasogastric tube 4 in real time. When the protective film 18 is ruptured through the pre-fracture mark 19, the liquid food in the nasogastric tube 4 is in a stationary state, and timely care should be provided to avoid injury to the patient.

The silica gel bag 15 drives the support disc 12 to rise when it is inflated, and the inflation speed is controllable, so as to achieve the purpose of accurately controlling the rising speed of the support disc 12; Secondly, the silica gel bag 15 is food-grade silica gel, which has the advantages of excellent elasticity, being able to recover to its original shape under pressure, high tear strength, wide temperature resistance range (-50°C ~ 250°C), good biocompatibility, and being able to directly contact skin and food.

[0020] Example 2: refer to Figure 3 、 Figure 6 and Figure 8 , the protection mechanism includes an air leakage pipe 16, a protection film 18 and a vent hole 20; The air leakage tube 16 is screwed and connected to the side wall of the support ring 21, and a sealing thread is fixedly connected to the side wall of the air leakage tube 16, so that the air leakage tube 16 is easily sealed and connected to the side wall of the support ring 21 through the sealing thread. The air leakage tube 16 is also conveniently removed and replaced through the sealing thread, so that medical staff can replace the air leakage tube 16 that can withstand different pressures according to the patient's needs. At the same time, a protective film 18 is fixedly connected to the middle position of the inner part of the leakage pipe 16, and a pre-broken mark 19 is integrally formed on the protective film 18, so that when the silica gel bag 15 is inflated, it pushes the support disc 12 to rise, and when the support disc 12 squeezes the liquid food bag 10, when the flow of liquid food in the liquid food bag 10 is blocked, the silica gel bag 15 will have difficulty in pushing the support disc 12 to rise, and the gas in the silica gel bag 15 will break through the protective film 18 and be released from the ventilation pipe 6, so as to avoid excessively pushing the support disc 12 to rise, causing serious blockage of the liquid food in the liquid food bag 10 or other accidents. In addition, the pre-broken mark 19 integrally formed on the protective film 18 facilitates the protective film 18 to quickly rupture when it is under pressure. Secondly, vent holes 20 are provided at both ends of the leakage pipe 16, so that the leakage pipe 16 is connected to the inside of the silica gel bag 15 through the vent holes 20 at both ends, so that when the silica gel bag 15 is deflated, it is easy to discharge through the two vent holes 20.

The connecting tube 3 is convenient for passing through the inside of the connecting hole 8 and is located above the upper cover 2 to be connected to the nasogastric tube 4 for use; Secondly, a plurality of limiting grooves 11 are provided on the inner wall of the main tube 1, and a plurality of limiting balls 17 are rollingly connected to the side wall of the support disc 12, and the limiting grooves 11 and the limiting balls 17 are arranged to slide with each other in a limiting manner, so that when the support disc 12 is pushed by the silicone bag 15 during use, it can be limited and slid up by the plurality of limiting grooves 11 and the limiting balls 17. When the silicone bag 15 is deflated, the support disc 12 can be limited and slid up and down by the plurality of limiting grooves 11 and the limiting balls 17, so that the support disc 12 can be stably raised and lowered for use.

[0022] Working principle: The lower base 5 is fixedly connected to the bottom of the main tube 1, so that the main tube 1 can be supported by the lower base 5 during use, and a support ring 21 is fixedly connected to the top of the lower base 5 inside the main tube 1, so that the lower base 5 is sealed with a silica gel bag 15 through the support ring 21, so that when the support disc 12 needs to be adjusted to rise or fall inside the main tube 1, the silica gel bag 15 can be inflated to push the support disc 12 to rise, and when the support disc 12 needs to be lowered, the silica gel bag 15 can slowly deflate the support disc 12 is adjusted downward inside the main tube 1 to complete the control of the support disc 12 to rise and fall. At the same time, a protective film 18 is fixedly connected to the middle position inside the leakage pipe 16, and a pre-break mark 19 is integrally formed on the protective film 18, so that the silica gel bag 15 pushes the support disc 12 to rise when it is inflated, and the support disc 12 squeezes the liquid food bag 10. When the flow of liquid food in the liquid food bag 10 is blocked, the silica gel bag 15 will find it difficult to push the support disc 12 to rise, and the gas in the silica gel bag 15 will break through the protective film 18, and the gas will flow out from the leakage pipe 16. The trachea 6 is deflated to avoid excessively pushing the support disc 12 to rise, causing serious blockage of the liquid food in the liquid food bag 10 or other accidents, and the pre-broken marks 19 integrally formed on the protective film 18 are convenient for the protective film 18 to quickly rupture when it is under pressure.

When the liquid food bag 10 is stably placed on the support disc 12 through the lower bottom plate 14, the silicone bag 15 expands. When pushing the support disc 12, the liquid food bag 10 will be squeezed because the upper top plate 13 fits against the bottom of the upper cover 2 and the lower bottom plate 14 fits against the top of the support disc 12, so that the liquid food bag 10 is squeezed, so that the liquid food loaded in the liquid food bag 10 can be discharged from the connecting tube 3 and finally guided into the patient's body through the nasogastric tube 4.
