Description

Technical Field

[0001] The present invention relates to the technical field of nasogastric feeding devices, and in particular to a heat-insulating and pressurized nasogastric feeding device. Background Art

[0002] Nasogastric feeding, also known as nasogastric feeding, is a technology that, under special circumstances, inserts a tube into the stomach through the nasal cavity to provide food, water and medicine to patients who cannot swallow independently, so as to maintain their metabolism, weight and nutrition. Nasogastric feeding is suitable for people who cannot eat by mouth and patients who cannot open their mouths. Food needs to be beaten into chyle or solid food needs to be crushed into liquid or paste with a food grinder. Food, water and medicine are slowly injected into the stomach with a syringe or infusion set. After the infusion is completed, the end of the gastric tube is folded back, wrapped with gauze and fixed on a large sheet.

[0003] After searching, a Chinese patent with publication number CN115590769A discloses a nasogastric feeding device, including a connecting seat, a rotating assembly is arranged on the surface of the connecting seat, and the rotating assembly includes a fixed ring, an L-shaped connecting rod is connected to one side of the fixed ring, a rotating sleeve is arranged on the surface of the L-shaped connecting rod, and a plurality of connecting frames are connected to the surface of the rotating sleeve, and a plurality of syringes are respectively arranged inside the plurality of connecting frames, and a plurality of pushing assemblies are respectively arranged inside the plurality of syringes, and the connecting rod is arranged inside the connecting seat, and a connecting piece is connected to one end of the connecting rod. A nasogastric feeding device provided by the present invention has a rotating assembly arranged on the surface of the connecting seat and is used in conjunction with a plurality of syringes to store a plurality of different liquid foods at the same time, and is also beneficial for medical staff to feed liquid foods to patients, and can improve the convenience of operation, and can replace the use of a single syringe.

[0004] However, the above-mentioned device needs to be used to manually inject food, and the speed of food injection cannot be accurately controlled during manual operation. If the speed of food injection through nasogastric feeding is too fast, it may cause gastrointestinal irritation to the patient, causing the patient to experience nausea, vomiting, abdominal distension and other discomfort symptoms, and may also cause the risk of aspiration. Too fast an injection speed may also cause food reflux, causing food or liquid to enter the respiratory tract, causing aspiration pneumonia, suffocation and other serious consequences. If the speed of food injection through nasogastric feeding is too slow, the patient may feel uncomfortable and anxious due to the long nasogastric feeding process. In addition, long-term nasogastric feeding may cause food to cool, thereby irritating the patient's stomach. Therefore, it is necessary to reasonably control the injection speed during nasogastric feeding and ensure that the temperature of the food is appropriate.

[0005] Therefore, the present application provides a heat-insulating pressurized nasogastric feeding device to meet the problem of stably and accurately controlling the injection speed. Summary of the invention

[0067] Beneficial effects of the present invention:

[0068] 1. This kind of heat-insulating pressurized nasogastric feeding device, by setting a servo motor to drive the threaded rod to move vertically downward, cooperates with the pressurizing component, can squeeze food out of the feeding cup at a stable rate, ensures that the food is injected into the user's stomach evenly and stably, avoids stomach discomfort and other risks caused by uneven injection speed, and improves the user's comfort. By adjusting the speed of the servo motor, the food injection speed can be flexibly adjusted to meet the personalized needs of different users, further improving the adaptability and user experience of the system. The whole device is centrally arranged in a box, which is convenient to carry to different scenes. The user can put it aside to automatically inject food without manual operation, thereby freeing the user's hands and allowing them to continue other tasks while injecting food, improving the convenience of life.

[0069] 2. This type of heat-insulating pressurized nasogastric feeding device, by setting the cooperation of the guide ring and the slider, can ensure the precise alignment of the pressurizing component and the feeding cup even if there is a slight error, avoiding the situation where the fixed plate cannot smoothly enter the feeding cup or causes damage to the feeding cup due to misalignment, thereby improving the fault tolerance and convenience of use of the device.

[0070] 3. This heat-insulating pressurized nasogastric feeding device achieves the heat preservation of food by setting up a water tank, a heating rod, a water bag, a catheter and other components for coordinated use. At the same time, as the food is injected, the L-shaped rod drives the elastic ring to move downward, gradually pressing the water in the water bag back into the water tank, ensuring that the water in the water bag is always at the same height as the remaining food, which not only maintains the appropriate temperature of the food, but also saves resources and avoids waste of heat energy. The servo motor rotates and drives the stirring shaft and the stirring blades to rotate at the same time, so that the water flow pressures at the connecting ends of the two catheters and the water tank are different, thereby driving the water flow to circulate in the water bag and the water tank, ensuring the continuous heat preservation of the food for a long time.

[0071] 4. This heat preservation and pressurized nasogastric feeding device, through the coordinated use of components such as the connecting arm, piston rod, piston plate, one-way valve and water supply pipe, can meet the user's drinking water needs after the food is injected, and at the same time, the nasogastric feeding tube is properly flushed to ensure the cleanliness of the device. After flushing, the hot water is drawn out again into the feeding cup to avoid the residue on the wall of the cup drying up and causing difficulty in cleaning. Through the connecting pipe, anti-blocking box and fixed pipe, large pieces of food are trapped in the anti-blocking box by the filter plate, avoiding the problem of food blocking the nasogastric feeding tube and causing difficulty in cleaning and replacement.

[0087] like Figures 1 to 10As shown, the heat preservation and pressurized nasogastric feeding device includes a box body 1; a fixing frame 2, which is fixedly mounted on the inner wall of the box body 1; a feeding cup 21, which is arranged on the fixing frame 2 and has an opening at the bottom of the feeding cup 21; a fixing plate 22, which is fixedly mounted on the inner wall of the box body 1; a guide tube 23, which is fixedly mounted on the end of the fixing plate 22 close to the feeding cup 21; a threaded rod 24, which is slidably mounted in the guide tube 23; a pressurizing component, which is arranged on the threaded rod 24; a gear 1 25, which is rotatably mounted on the end of the guide tube 23 away from the fixing plate 22, and is sleeved on the threaded rod 24 and threadedly connected to the threaded rod 24; a servo motor 26, which is fixedly mounted on the inner top wall of the box body 1; a gear 27, which is fixedly mounted on the output end of the servo motor 26 and meshes with the gear 1 25; a heat preservation component, which is arranged in the box body 1; an anti-blocking component, which is arranged in the box body 1; a movable door 9, which is rotatably mounted on the box body 1; a nasogastric feeding tube 10, which is arranged on the box body 1;

[0088] When in use, liquid or paste can be poured into the feeding cup 21, the nasogastric tube 10 can be connected to the feeding cup 21, the feeding cup 21 can be stuck on the fixing frame 2, and the servo motor 26 can be started to drive the gear 2 27 to rotate while driving the gear 1 25 to rotate, thereby driving the threaded rod 24 to move vertically downward under the action of the guide tube 23, and driving the pressurizing assembly to move downward to cooperate with the feeding cup 21 to squeeze out the food at a stable rate, thereby ensuring a uniform and stable injection rate, and the injection speed can be changed by adjusting the motor speed, which can ensure the user's stomach comfort and avoid stomach sensitivity and other risks. In addition, by centrally arranging the device in the box 1, it is convenient for the user to carry it to different scenes, and it can be placed aside to automatically inject food, which improves the adaptability of the system and frees the user's hands, allowing the user to continue his own business while injecting food.

[0089] like Figures 3 to 6 As shown, the pressurizing assembly includes: a fixed plate 3, fixedly mounted on the end of the threaded rod 24 away from the fixed plate 22; four slide grooves 31, which are arranged in a ring array in the fixed plate 3; four sliders 32, which are respectively slidably mounted in the four slide grooves 31, and the ends of the four sliders 32 are all quarter-circular rings adapted to the fixed plate 3; four springs 33, which are respectively fixedly mounted between the four sliders 32 and the four slide grooves 31; a guide ring 34, which is fixedly mounted on the top of the feeding cup 21 and is arranged at an angle adapted to the slider 32; an injection port is opened on the fixed plate 3, a sealing plug 8 is slidably mounted in the injection port, and a scale line is arranged on the feeding cup 21;

[0090] When the threaded rod 24 moves downward, it can contact the outer side of the slider 32 under the guidance of the guide ring 34 and squeeze it radially inward until the four sliders 32 and the fixed disk 3 form a complete disk, and can be adapted to the feeding cup 21 to play a sealing and squeezing role, and stably squeeze the food out of the opening. Through the cooperation of the guide ring 34 and the slider 32, it can be ensured that each time the feeding cup 21 is taken out for cleaning or other operations and put back, even if there is a slight error, the fixed disk 3 will not be unable to smoothly enter the feeding cup 21 due to the misalignment of the pressurizing component and the feeding cup 21, and even cause damage to the feeding cup 21. The placement deviation can be corrected under the action of the guide ring 34, thereby improving the fault tolerance of the device and making it more convenient for users to use. According to the volume of food to be injected, the fixed disk 3 can be lowered to the position indicated by the scale line, and then the sealing plug 8 can be opened to inject food through the injection port, so that the food intake can be accurately controlled, helping users to better control nutrition intake, and avoiding the situation of gas being pressed during nasogastric feeding, thereby enhancing the safety of the device.

[0091] like Figures 1 to 5 As shown, the heat preservation assembly includes: a water tank 4, which is fixedly installed in the box body 1 and is arranged higher than the feeding cup 21; a water supply port 41, which is arranged on the top of the side wall of the water tank 4; a heating rod 42, which is fixedly installed at the bottom of the water tank 4; a water bag 43, which is sleeved on the feeding cup 21; two guide tubes 44, which are fixedly installed between the bottom of the water bag 43 and the bottom of the water tank 4; an elastic ring 45, which is slidably sleeved on the feeding cup 21; a connecting block 46, which is fixedly installed on the elastic ring 45, and the other end is slidably connected to the box body 1; an L-shaped rod 47, which is fixedly installed on the top of the threaded rod 24 and is adapted to the connecting block 46; a clearance groove 48, which is opened on the guide tube 23 and is connected to the L-shaped Rod 47 is adapted; a circulation component is arranged in the water tank 4; a water adding component is arranged on the water tank 4; the circulation component includes: a driven wheel 5, rotatably mounted on the outer top wall of the water tank 4; a driving wheel 51, fixedly mounted on the output end of the servo motor 26; a synchronous belt 52, sleeved on the driven wheel 5 and the driving wheel 51; a stirring shaft 53, fixedly mounted on the driven wheel 5 and passing through the water tank 4; a plurality of stirring blades 54, fixedly mounted on the stirring shaft 53 in a ring array; wherein two conduits 44 are symmetrically arranged at both ends of the bottom of the side wall of the water tank 4, and the positions of the stirring blades 54 are arranged corresponding to the positions of the two conduits 44; the stirring blades 54 are arranged in an arc shape;

[0092] Before use, a certain amount of water is injected into the water tank 4 through the water inlet 41, and the temperature of the water is maintained at about 38° under the action of the heating rod 42. The water flows into the water bag 43 through the conduit 44, which can keep the feeding cup 21 wrapped by the water bag 43 warm. As the food is injected, the L-shaped rod 47 can contact the connecting block 46 and drive the elastic ring 45 to move downward, gradually pressing the water in the water bag 43 back into the water tank 4, so that the water in the water bag 43 is always consistent with the height of the remaining food. While ensuring that the food maintains a suitable temperature, resources can be saved and heat energy can be avoided. When the servo motor 26 rotates, the driven wheel 5 and the stirring shaft 53 can be driven to rotate through the synchronous belt 52, thereby driving the stirring blade 54 to rotate, so that the water flow pressures at the connection ends of the two conduits 44 and the water tank 4 are different. The arc setting can improve the driving effect on the water flow, thereby driving the water flow to circulate in the water bag 43 and the water tank 4, ensuring a long-term continuous insulation effect on the food.

[0093] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the water adding assembly includes: a sealing cylinder 7, fixedly mounted on the outer wall of the bottom of the water tank 4; a piston plate 71, slidably mounted in the sealing cylinder 7; a piston rod 72, fixedly mounted on the end of the piston plate 71 away from the water tank 4 and arranged in an L shape; a connecting arm 73, fixedly mounted on the end of the L-shaped rod 47 away from the threaded rod 24, and adapted to the piston rod 72; a water supply pipe 74, arranged between the sealing cylinder 7 and the feeding cup 21; a connecting port, opened on the bottom wall of the water tank 4 and connected to the sealing cylinder 7; wherein a one-way valve 1 75 is arranged at the connecting port, a one-way valve 2 76 is arranged at the connection point between the water supply pipe 74 and the sealing cylinder 7, and a one-way valve 3 is arranged at the other end of the water supply pipe 74;

[0094] After adding water into the water tank 4 according to the required amount of water, when the threaded rod 24 moves downward to inject food, the piston rod 72 is driven by the connecting arm 73, and then the piston plate 71 is driven to pump water. At this time, the one-way valve 1 75 is opened, and the one-way valve 2 76 and the one-way valve 3 are closed. When the injection is completed, the servo motor 26 is reversed to drive the threaded rod 24 to rise, and then the piston plate 71 drains water. At this time, the one-way valve 1 75 is closed, and the one-way valve 2 76 and the one-way valve 3 are opened. At this time, hot water can enter the feeding cup 21 through the water supply pipe 74. After extracting an appropriate amount of hot water, the servo motor 26 can be turned forward again to inject hot water into the nasogastric tube 10. At this time, the user's need for drinking water can be met, and the nasogastric tube 10 can be properly rinsed at the same time to ensure that the device is used cleanly. After rinsing the nasogastric tube 10, the servo motor 26 can be reversed again to extract hot water into the feeding cup 21 again. After the threaded rod 24 is reset, the residue on the inner wall of the feeding cup 21 can be prevented from drying up and causing cleaning difficulties.

[0095] like Figure 7As shown, the anti-blocking assembly includes: a connecting tube 6, which is arranged at the bottom of the feeding cup 21 and is connected to the opening; an anti-blocking box 61, which is fixedly installed at the other end of the connecting tube 6 and is connected to the connecting tube 6; a guide frame 62, which is fixedly installed in the anti-blocking box 61; a filter plate 63, which is slidably installed in the guide frame 62 and is vertically arranged with the connecting tube 6; a box cover 64, which is threadedly sleeved on the top of the anti-blocking box 61; a fixed tube 65, which is fixedly installed at one end of the anti-blocking box 61 away from the connecting tube 6, and is connected with the anti-blocking box 61; wherein a one-way valve 4 is arranged at the connection between the connecting tube 6 and the opening; the fixed tube 65 is arranged to penetrate the box body 1 and a dust cover is arranged at the end of the fixed tube 65 extending out of the box body 1; a male Luer connector is arranged at the end of the fixed tube 65 extending out of the box body 1, and a female Luer connector is arranged at the end of the nasogastric tube 10 connected to the fixed tube 65;

[0096] When food is squeezed out, it passes through the connecting tube 6, the anti-blocking box 61 and the fixed tube 65 in sequence, and large pieces of food that are not completely crushed can be intercepted by the filter plate 63 in the anti-blocking box 61, and thus retained in the anti-blocking box 61. Since the anti-blocking box 61 is relatively large, the use time and cleaning interval of the equipment can be extended, and the problem of difficulty in cleaning and replacement caused by food blocking the nasogastric tube 10 can be avoided, thereby extending the service life of the nasogastric tube 10 and reducing the cost of use. After use, the blocked anti-blocking box 61 can be cleaned by removing the box cover 64 and the filter plate 63 to ensure the cleanliness of the device. The Luer connector can make the connection between the nasogastric tube 10 and the fixed tube 65 simpler and more convenient. The working principle and connection method of the Luer connector are both existing mature technologies and will not be elaborated on here.
