Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a nursing feeding device. Background Technology

[0002] Currently, some patients or elderly people have difficulty eating or are even unable to eat. In most cases, these patients need to consume liquid food. During the nursing process, a spoon or tube is often used to feed liquid food. However, when feeding with a spoon, liquid food is easily spilled, so a tube is used to introduce liquid food into the patient's mouth. There are two methods for feeding liquid food: one is to squeeze the air bag to pressurize the container containing the liquid food, causing the liquid food to flow from the container into the mouth through the tube; the other is to hang the liquid food bag with the tube attached at a high place, and the liquid food in the bag flows into the mouth through the tube under the influence of gravity.

[0003] Based on the above, the inventors have discovered the following problems: current nursing feeding devices do not have an on / off function and cannot control the start and stop of liquid food delivery. If the patient experiences choking or vomiting during feeding, the delivery cannot be cut off in time, and the liquid food continues to enter, aggravating aspiration and potentially causing serious problems such as suffocation. This poses a significant threat, especially to patients with swallowing difficulties such as those who are post-operative or in a coma.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a nursing and feeding device, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a nursing feeding device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A nursing feeding device includes a food storage component, a switching component, and a feeding component. The switching component is located below the food storage component, and the feeding component is located below the switching component. The switching component is used to enable the connection and disconnection between the food storage component and the feeding component. The switching component includes a first connector, the bottom end of which is connected to a connecting tube, and the bottom end of the connecting tube is connected to a second connector. A spherical chamber is formed inside the connecting tube, and a spherical seat is rotatably connected inside the spherical chamber. A flow channel is formed inside the spherical seat, and a rotating rod is installed on one side of the outer wall of the spherical seat. The rotating rod extends through the connecting tube to the outside at the end away from the spherical seat. The food storage component includes a food storage bottle, the bottom end of which has a first connecting groove, and the first connector is located inside the first connecting groove. The feeding component includes a connecting seat, which is located inside the second connector.

[0008] Furthermore, a drive seat is installed on one side of the outer wall of the connecting pipe, and the rotating rod extends through the drive seat into the interior at the end away from the spherical seat. The end of the rotating rod away from the spherical seat is rotatably connected to the inner wall of the drive seat. A worm gear is sleeved on the outside of the rotating rod, and the worm gear is connected to a worm.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the worm and the worm wheel, when the worm rotates, the worm meshes with the worm wheel, thereby realizing the rotation of the rotating rod, causing the spherical seat to rotate in the spherical cavity of the connecting pipe. Under the continuous rotation, the flow channel in the spherical seat is misaligned with the two openings of the connecting pipe, so that the outer wall of the spherical seat seals the two openings of the connecting pipe. At the same time, due to the self-locking property between the worm and the worm wheel, the spherical seat, after being rotated and adjusted, maintains a stable position under the self-locking action.

[0010] Furthermore, both ends of the worm are rotatably connected to the inner wall of the drive seat, and one end of the worm extends through the drive seat to the outside and is fitted with a knob.

[0011] The advantage of adopting the above-mentioned further solution is that, by setting the knob, when the user turns the knob, it is easy to drive the worm gear to rotate inside the drive seat.

[0012] Furthermore, the rotating rod passes through the drive seat at the end away from the spherical seat, and a circular plate is installed at the end of the rotating rod away from the spherical seat. A pair of limiting grooves are formed on the circular plate, and a limiting rod is provided inside one end of each pair of limiting grooves. One end of the limiting rod is fixedly connected to the outer wall of the drive seat, and the outer wall of one end of the limiting rod slides in cooperation with the inner wall of the limiting groove. The limiting groove is arc-shaped, and the arc of the limiting groove is 0 degrees to 90 degrees.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since the curvature range of the limiting groove is 0 degrees to 90 degrees, and the outer wall of the limiting rod slides with the inner wall of the limiting groove, when the rotating rod rotates, the circular plate installed at one end of it rotates, causing the position of the limiting rod in the limiting groove to change. When the limiting rod abuts against the other end of the limiting groove, the rotating rod can no longer rotate. At this time, the rotating rod has rotated 90 degrees, so that the originally vertical flow channel becomes horizontal, ensuring that the flow channel is completely misaligned with the two openings of the connecting pipe and that the outer wall of the spherical seat completely seals the two openings of the connecting pipe.

[0014] Furthermore, the second connector has a second connecting groove inside at the end away from the connecting tube. The inner wall of the second connecting groove and the outer wall of the connecting seat are both threaded. The second connecting groove and the connecting seat are threaded together. The inner wall of the first connecting groove and the outer wall of the first connector are both threaded. The first connecting groove and the first connector are threaded together.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since the second connecting groove is threadedly connected to the connecting seat and the first connecting groove is threadedly connected to the first connecting head, the food storage component, the switching component, and the feeding component can be quickly disassembled and assembled. When it is necessary to change the liquid food, the food storage component storing different liquid foods can be replaced by the quickly detachable feeding component, so that the feeding head does not need to be removed from the patient's mouth, thereby improving the patient's comfort. When it is necessary to add liquid food, the medical staff holds the food storage component upside down so that the switching component is facing upwards and then quickly removes the switching component, adds liquid food into the food storage bottle through the first connecting groove, and quickly installs the switching component after adding.

[0016] Furthermore, a connecting strip is installed at the top of the food storage bottle, and a hanging ring is installed at the center of the upper end of the connecting strip. The food storage bottle is transparent, and the inside of the food storage bottle is filled with liquid food.

[0017] The beneficial effects of adopting the above-mentioned further solution are that, by setting the hanging ring, it is easy to hang the feeding device on the infusion stand hook or other designated positions, and by making the food storage bottle transparent, it is easy to observe the amount of liquid food remaining in the food storage bottle during the feeding process.

[0018] Furthermore, the bottom end of the connecting seat is connected to a feeding tube, and the end of the feeding tube away from the connecting seat is connected to a feeding head. The inside of the feeding head is hollow, and the feeding head has several liquid food openings.

[0019] The beneficial effect of adopting the above-mentioned further solution is that when the on / off component is in the open state, the liquid food in the food storage bottle will pass through the first connecting groove, the first connecting head, the connecting tube, the ball seat and its internal flow channel, the second connecting head, the connecting seat, the feeding tube and then be discharged from the feeding head under the action of gravity. When the feeding head is inserted into the patient's mouth, the liquid food will reach the inside of the patient's oral cavity through the liquid food opening on the feeding head, so that the patient can swallow.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: When the on / off component is in the open state, the liquid food in the storage bottle will pass through the first connecting groove, the first connecting head, the connecting pipe, the spherical seat and its internal flow channel, the second connecting head, the connecting seat, the feeding hose, and then be discharged from the feeding head under the action of gravity. When the feeding head is inserted into the patient's mouth, the liquid food will reach the patient's oral cavity through the liquid food opening on the feeding head, so as to facilitate the patient's swallowing. When it is necessary to change the liquid food, the user turns the knob to drive the worm gear to rotate inside the drive seat. Since the worm gear meshes with the worm wheel, the rotating rod is rotated, so that the spherical seat rotates in the spherical cavity of the connecting pipe. Since the curvature range of the limiting groove is 0 degrees to 90 degrees, and the outer wall of the limiting rod is in contact with the limiting groove... The inner wall slides together. When the rotating rod rotates, the circular plate installed at one end rotates, causing the position of the limiting rod in the limiting groove to change. When the limiting rod abuts against the other end of the limiting groove, the rotating rod can no longer rotate. At this time, the rotating rod has rotated 90 degrees, so that the originally vertical flow channel becomes horizontal, ensuring that the flow channel is completely misaligned with the two openings of the connecting pipe and that the outer wall of the spherical seat completely seals the two openings of the connecting pipe. At the same time, due to the self-locking property between the worm and the worm wheel, the spherical seat remains stable under the self-locking action after the rotation adjustment. Then, the connecting seat is loosened until it is quickly removed from the second connector to replace the food storage components for storing different liquid foods, so that the feeding head does not need to be removed from the patient's mouth, thereby improving the patient's comfort.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a nursing feeding device, including a food storage component 1, a switching component 2, and a feeding component 3. The switching component 2 is located below the food storage component 1, and the feeding component 3 is located below the switching component 2. The switching component 2 is used to realize the connection and disconnection between the food storage component 1 and the feeding component 3. The switching component 2 includes a first connector 21, the bottom end of which is connected to a connecting pipe 23. The bottom end of the connecting pipe 23 is connected to a second connector 22. A spherical chamber is formed inside the connecting pipe 23, and a spherical seat 24 is rotatably connected inside the spherical chamber. A flow channel 25 is formed inside the spherical seat 24. A rotating rod 26 is installed on one side of the outer wall of the spherical seat 24. The rotating rod 26 extends through the connecting pipe 23 to the outside at the end away from the spherical seat 24. The food storage component 1 includes a food storage bottle 11, the bottom end of which has a first connecting groove 14. The first connector 21 is located inside the first connecting groove 14. The feeding component 3 includes a connecting seat 31, which is located inside the second connector 22. When the switching component 2 is in the open state, the liquid food in the food storage bottle 11 will pass through the first connecting groove 14, the first connector 21, the connecting tube 23, the spherical seat 24 and its internal flow channel 25, the second connector 22, the connecting seat 31, the feeding tube 32, and then be discharged from the feeding head 33. When the feeding head 33 is inserted into the patient's mouth, the liquid food will reach the patient's oral cavity through the liquid food opening on the feeding head 33, so that the patient can swallow. When it is necessary to change the liquid food, the rotating rod 26 rotates, so that the spherical seat 24 rotates in the spherical cavity of the connecting tube 23. Under the continuous rotation, the flow channel 25 in the spherical seat 24 is misaligned with the two openings of the connecting tube 23, so that the outer wall of the spherical seat 24 seals the two openings of the connecting tube 23, so that the switching component 2 and the feeding component 3 can be disassembled and the food storage component 1 can be replaced.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 This utility model provides a technical solution: a drive seat 27 is installed on one side of the outer wall of the connecting pipe 23. A rotating rod 26 extends through the drive seat 27 into the interior at the end away from the spherical seat 24. The end of the rotating rod 26 away from the spherical seat 24 is rotatably connected to the inner wall of the drive seat 27. A worm gear 28 is sleeved on the outside of the rotating rod 26. A worm 29 is drivenly connected to the worm gear 28. Both ends of the worm 29 are rotatably connected to the inner wall of the drive seat 27. One end of the worm 29 extends through the drive seat 27 into the outside and is sleeved with... The knob 210 and the rotating rod 26 pass through the drive seat 27 at the end away from the spherical seat 24. A circular plate 211 is installed at the end of the rotating rod 26 away from the spherical seat 24. A pair of limiting grooves 212 are formed on the circular plate 211. A limiting rod 213 is provided inside one end of each pair of limiting grooves 212. One end of the limiting rod 213 is fixedly connected to the outer wall of the drive seat 27. The outer wall of one end of the limiting rod 213 slides in cooperation with the inner wall of the limiting groove 212. The limiting groove 212 is arc-shaped and the curvature of the limiting groove 212 is 0 degrees. ~90 degrees. When the user rotates knob 210, it drives worm 29 to rotate inside drive seat 27. Since worm 29 meshes with worm wheel 28, it causes rotating rod 26 to rotate, causing spherical seat 24 to rotate within spherical cavity of connecting pipe 23. Since the arc range of limiting groove 212 is 0 degrees to 90 degrees, and the outer wall of limiting rod 213 slides with the inner wall of limiting groove 212, when rotating rod 26 rotates, the circular plate 211 installed at one end rotates, causing limiting rod 213 to be positioned within limiting groove 212. When the position changes, after the limiting rod 213 abuts against the other end of the limiting groove 212, the rotating rod 26 can no longer rotate. At this time, the rotating rod 26 has rotated ninety degrees, so that the originally vertical flow channel 25 becomes horizontal, ensuring that the flow channel 25 is completely misaligned with the two openings of the connecting pipe 23 and the outer wall of the spherical seat 24 completely seals the two openings of the connecting pipe 23. At the same time, due to the self-locking property between the worm 29 and the worm wheel 28, the spherical seat 24, after being rotated and adjusted, maintains a stable position under the self-locking action.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: A second connecting head 22 has a second connecting groove 214 inside at the end furthest from the connecting tube 23. The inner wall of the second connecting groove 214 and the outer wall of the connecting seat 31 are both threaded, and the second connecting groove 214 is threaded to the connecting seat 31. The inner wall of the first connecting groove 14 and the outer wall of the first connecting head 21 are both threaded, and the first connecting groove 14 is threaded to the first connecting head 21. A connecting strip 12 is installed at the top of the food storage bottle 11, and a hanging ring 13 is installed at the center of the upper end of the connecting strip 12. The food storage bottle 11 is transparent. A feeding hose 32 is connected to the bottom end of the connecting seat 31. A feeding head 33 is connected to the end of the feeding hose 32 furthest from the connecting seat 31. The feeding head 33 is hollow inside and has several feeding openings. Because the second connecting groove 214 is threaded to the connecting seat 31, and the first connecting groove 14 is threaded to the first connecting head 21, the food storage component 1 is thus realized. The quick-release mechanism between the on / off component 2 and the feeding component 3 allows for easy replacement of the liquid food by quickly removing the feeding component 3 to replace the storage component 1 containing different liquid foods. This eliminates the need to remove the feeding head 33 from the patient's mouth, thus improving patient comfort. The hanging ring 13 facilitates hanging the feeding device on the IV stand hook or other designated location. The transparent storage bottle 11 allows for easy observation of the remaining liquid food during feeding. When the on / off component 2 is open, the liquid food in the storage bottle 11 will pass through the first connecting groove 14, the first connecting head 21, the connecting tube 23, the ball seat 24 and its internal flow channel 25, the second connecting head 22, the connecting seat 31, and the feeding tube 32 under gravity, and then be discharged from the feeding head 33. When the feeding head 33 is inserted into the patient's mouth, the liquid food will reach the inside of the patient's mouth through the liquid food opening on the feeding head 33, making it easy for the patient to swallow.

[0032] Specifically, the working principle of this nursing feeding device is as follows: In use, the feeding device is hung on an IV stand or other location via the hanging ring 13. The feeding head 33 is inserted into the patient's mouth. When the on / off component 2 is open, the liquid food in the storage bottle 11 will pass through the first connecting groove 14, the first connecting head 21, the connecting tube 23, the spherical seat 24 and its internal flow channel 25, the second connecting head 22, the connecting seat 31, and the feeding tube 32 under gravity, and then be discharged from the feeding head 33. Inserting the feeding head 33 into the patient's mouth allows the liquid food to reach the patient's oral cavity through the liquid food opening on the feeding head 33, facilitating swallowing. When the liquid food needs to be changed, the user rotates the knob 210 to drive the worm gear 29 to rotate inside the drive seat 27. Because the worm gear 29 meshes with the worm wheel 28, the rotating rod 26 rotates, causing the spherical seat 24 to rotate within the spherical cavity of the connecting tube 23. Since the curvature range of the limiting groove 212 is 0 degrees to 90 degrees... The outer wall of the limiting rod 213 slides in conjunction with the inner wall of the limiting groove 212. When the rotating rod 26 rotates, the circular plate 211 installed at one end rotates, causing the position of the limiting rod 213 in the limiting groove 212 to change. When the limiting rod 213 abuts against the other end of the limiting groove 212, the rotating rod 26 can no longer rotate. At this time, the rotating rod 26 has rotated ninety degrees, so that the originally vertical flow channel 25 becomes horizontal, ensuring that the flow channel 25 is completely misaligned with the two openings of the connecting pipe 23 and the outer wall of the spherical seat 24 completely seals the two openings of the connecting pipe 23. At the same time, due to the self-locking property between the worm 29 and the worm wheel 28, the spherical seat 24 remains stable under the self-locking action after the rotation adjustment. Then, the connecting seat 31 is loosened until it is quickly removed from the second connector 22 to replace the food storage component 1 for storing different liquid foods, so that the feeding head 33 does not need to be removed from the patient's mouth, thereby improving the patient's comfort.

[0033] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
