Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a multifunctional feeding device. Background Art

[0002] Patients with digestive system diseases, bedridden patients, or those with dysphagia require supplemental feeding with liquid feeding devices. Existing feeders are relatively simple in structure and have a small capacity. They require frequent refills, which is not only time-consuming and laborious but also easily leads to contamination of the feeder.

[0003] To this end, a Chinese patent with authorization announcement number CN222854263U discloses a postoperative feeder, which uses an injection structure. After the capacity tank is filled with liquid food, it is engaged with the threaded tube. The capacity tank is inverted so that the threaded tube is aligned with the threaded groove tube and rotated to connect the two. When the threaded tube is rotated into the threaded groove tube, the first push rod presses the second push rod and squeezes the movable plug. At this time, the two springs are compressed by pressure, so that the second push rod drives the movable plug to move upward in the threaded tube, thereby exposing the through hole in the capacity tank. At this time, the liquid food in the capacity tank can flow into the extraction cylinder through the through hole, thereby increasing the amount of liquid food stored in the device each time, thereby achieving the purpose of increasing the flow rate of the device.

[0004] Existing liquid feeding devices generally use a syringe-like structure or a liquid feeding booster. During use, medical personnel use a core rod to pull a piston to suck the liquid food into the container, and then use the core rod to push the piston to inject the liquid food in the container into the patient's esophagus through a flexible tube. This type of liquid feeding device is generally only suitable for liquid foods with low viscosity and has relatively limited functions. When the liquid food has a high viscosity, medical personnel rely solely on thumb pressure to push the push rod, which is difficult to apply force and difficult to provide stable thrust to the push rod. Therefore, there is an urgent need for a feeding device with more diverse functions. Summary of the Invention

[0005] In view of the above problems, a multifunctional feeding device is provided, which solves the problem of the difficulty in pressing the existing feeder through a feeding cylinder, a pushing mechanism and an adjusting mechanism.

[0012] Preferably, a vertical plate is provided at one end of the feeding cylinder away from the accommodating chamber, a pull rod is slidably provided on the vertical plate, and the pull rod is connected to one end of the push rod away from the piston.

[0013] Preferably, a pull ring for grasping is provided on the movable handle.

[0014] Preferably, an anti-drop cap is sleeved on one end of the support shaft away from the adjustment seat, and the movable handle is located between the anti-drop cap and the adjustment seat.

[0015] Preferably, the feeding nozzle is a cylindrical structure with a conical tip extending from one end, and an annular groove is provided on the side of the cylindrical structure away from the tip; a convex ring that cooperates with the annular groove is provided at the front end of the feeding cylinder; the annular groove and the convex ring are connected by a threaded structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention facilitates feeding for medical personnel through the feeding cylinder, pushing mechanism, and adjustment mechanism. During feeding, the operator presses the movable handle, using the support shaft as a fulcrum and the movable handle as a lever to push the push rod. The push rod drives the piston, which in turn pushes the liquid food in the receiving chamber. The liquid food flows out through the feeding nozzle, making it easier to feed patients with difficulty eating. Furthermore, for liquid foods of different viscosities, the adjustment mechanism can adjust the position of the support shaft to adjust the length of the force arm on both sides of the support shaft, making feeding easier and solving the problem of the difficulty of pressing existing feeders.

[0018] 2. The present invention achieves the function of stably adjusting the position of the support shaft through the adjustment seat and the linear drive assembly. The adjustment seat is controlled to move by the linear drive assembly, and the support shaft is then driven to move by the adjustment seat. The movement path of the support shaft is stabilized by the cooperation of the guide groove and the adjustment seat. The adjustment seat can also provide stable support for the support shaft, ensuring that the support shaft can provide stable support for the movable handle. When adjusting the position of the support shaft, the adjustment seat is driven to move by the linear drive assembly, and one end of the movable handle is hinged to the push rod. Therefore, when the adjustment seat drives the support shaft to move, the support shaft moves along the straight groove on the movable handle, thereby changing the relative position of the support shaft and the movable handle.

[0019] 3. This invention utilizes a screw, bevel gear, and rotating handle to drive the adjustment base. This structure achieves precise motion conversion through the threaded connection between the screw and the adjustment base. The bevel gear transmission is smooth and reliable, and the rotating handle is easy and labor-saving to operate. The stop block design protects the transmission components while ensuring controllable adjustment range, making the support shaft position adjustment more precise and stable to meet diverse feeding needs. The entire mechanism is compact, highly efficient, simple to operate, and allows for smooth and seamless adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 5 : A multifunctional feeding device, including a feeding cylinder 1, which has a accommodating chamber for accommodating liquid food, and a piston 11 is movably arranged in the accommodating chamber; a feeding nozzle 12 is provided at the front end of the feeding cylinder 1; a pushing mechanism 2 for pushing the piston 11 to move is provided on the feeding cylinder 1; the pushing mechanism 2 includes a push rod 21, a support 22 and a movable handle 23, one end of the push rod 21 is connected to the piston 11, the support 22 is connected to the outer wall of the feeding cylinder 1, a support shaft 221 is movably provided on the support 22, a straight groove for slidingly fitting with the support shaft 221 is provided on the movable handle 23, and one end of the movable handle 23 is hinged to the end of the push rod 21 away from the piston 11; an adjusting mechanism 3 for adjusting the position of the support shaft 221 is provided on the support 22.

[0033] The present invention facilitates feeding for medical personnel through the feeding cylinder 1, the push mechanism 2, and the adjustment mechanism 3. During feeding, the operator presses the movable handle 23, using the support shaft 221 as a fulcrum. The movable handle 23 acts as a lever to push the push rod 21, which in turn drives the piston 11. The piston 11 then pushes the liquid food within the chamber, which then flows out through the feeding nozzle 12, making feeding easier for patients with feeding difficulties. Furthermore, for liquid foods of varying viscosities, the adjustment mechanism 3 can adjust the position of the support shaft 221 to adjust the length of the lever arm required to press on both sides of the support shaft 221, making feeding easier and resolving the difficulty of pressing on existing feeders. The feeding cylinder 1 is provided with a gripping handle 13. Adjusting the position of the support shaft 221 changes the swing amplitude of the movable handle 23, thereby controlling the travel distance of the push rod 21 and adjusting the amount of liquid food discharged. The device uses the push mechanism 2 to achieve smooth movement of the piston 11, ensuring uniform liquid food discharge. The adjustment mechanism 3 allows for flexible control of the liquid food volume, making it simple and convenient to operate and adaptable to different feeding needs.

[0034] Reference Figure 2 and Figure 5 : The adjustment mechanism 3 includes an adjustment seat 31 and a linear drive assembly 32; a guide groove 222 is opened on the support 22, the adjustment seat 31 is slidably set in the guide groove 222, and the support shaft 221 is connected to the adjustment seat 31; the linear drive assembly 32 is set on the support 22, and the linear drive assembly 32 is used to drive the adjustment seat 31 to move along the guide groove 222.

[0035] The present invention achieves the function of stably adjusting the position of the support shaft 221 through the adjustment seat 31 and the linear drive assembly 32. The adjustment seat 31 is controlled to move by the linear drive assembly 32, and the adjustment seat 31 is then used to drive the support shaft 221 to move. The movement path of the support shaft 221 is stabilized by the cooperation between the guide groove 222 and the adjustment seat 31. The adjustment seat 31 can also provide stable support for the support shaft 221, ensuring that the support shaft 221 can provide stable support for the movable handle 23. When adjusting the position of the support shaft 221, the adjustment seat 31 is driven to move by the linear drive assembly 32, and one end of the movable handle 23 is hinged to the push rod 21. Therefore, when the adjustment seat 31 drives the support shaft 221 to move, the support shaft 221 moves along the straight groove on the movable handle 23, thereby changing the relative position of the support shaft 221 and the movable handle 23.

[0036] Reference Figure 5 and Figure 6 : A screw 321 is rotatably provided in the guide groove 222, and the screw 321 is threadedly connected to the adjustment seat 31; a rotating handle 323 is rotatably provided on the support 22, and a bevel gear 322 is sleeved on the rotating handle 323 and the screw 321, and the two bevel gears 322 are meshed and connected.

[0037] The present invention realizes the function of driving the adjustment seat 31 to move through the screw 321, the bevel gear 322 and the rotating handle 323. A limit block is provided in the guide groove 222 of the support 22 for limiting the movement of the adjustment seat 31. When it is necessary to adjust the position of the support shaft 221, the medical staff turns the rotating handle 323, and the rotating handle 323 drives the screw 321 to rotate through the meshing transmission of the bevel gear 322. The rotational motion of the screw 321 is converted into a linear movement of the adjustment seat 31 along the guide groove 222, thereby driving the support shaft 221 to accurately adjust its position. The limit block provided in the guide groove 222 effectively limits the movement of the adjustment seat 31, prevents the adjustment seat 31 from excessive movement and collision with the bevel gear 322, and avoids damage to the bevel gear 322. This structure achieves precise motion conversion through the threaded engagement of screw 321 and adjustment base 31. Bevel gear 322 provides smooth and reliable transmission, while rotating handle 323 is easy and labor-saving to operate. The design of the limit block protects the transmission components while ensuring controllable adjustment range, making the position adjustment of support shaft 221 more precise and stable to meet different feeding needs. The entire mechanism is compact, highly efficient, easy to operate, and the adjustment process is smooth and seamless.

[0038] Reference Figure 1 and Figure 3 : The feeding nozzle 12 is detachably connected to the feeding tube 1.

[0039] The present invention realizes the function of making it convenient for the operator to replenish the liquid food in the accommodating chamber through the detachable feeding nozzle 12. Before feeding, the medical staff needs to first fill the liquid food into the accommodating chamber. At this time, the operator first removes the feeding nozzle 12 from the feeding cylinder 1, and controls the pushing mechanism 2 to make the piston 11 return to the starting position of the accommodating chamber to ensure that the accommodating chamber has enough space to accommodate the liquid food. The operator then pours the prepared liquid food into the accommodating chamber through the open end of the feeding cylinder 1. After the liquid food filling is completed, the feeding nozzle 12 is reinstalled on the feeding cylinder 1 to ensure that the connection is stable and leak-free. After completing the above preparations, the medical staff can control the movement of the piston 11 by operating the pushing mechanism 2, so that the liquid food is smoothly output through the feeding nozzle 12, realizing a precise and controllable feeding operation. The whole process is easy to operate and facilitates the rapid filling and hygienic feeding of liquid food.

[0040] Reference Figure 7 : A first hinge seat 211 is provided at one end of the push rod 21 away from the piston 11, and a fixed shaft 2111 is provided on the first hinge seat 211; an end of the movable handle 23 close to the push rod 21 is hinged to the fixed shaft 2111.

[0041] As the first embodiment of the present invention, the function of connecting the movable handle 23 and the push rod 21 is realized by the first hinge seat 211 and the fixed shaft 2111, so that the movable handle 23 can stably push the push rod 21 to move. The fixed shaft 2111 serves as a rigid connector, which can ensure that the hinge point between the movable handle 23 and the push rod 21 always remains stable, avoiding loosening or offset of the connection due to frequent swinging, thereby improving the durability of the overall structure. The fixed shaft 2111 provides a clear center of rotation, so that the swinging motion of the movable handle 23 can be more directly and efficiently converted into the linear motion of the push rod 21, reducing energy loss and ensuring the smoothness and controllability of the movement of the piston 11. The hinged design allows the movable handle 23 to rotate around the fixed shaft 2111, avoiding sliding friction between the push rod 21 and the movable handle 23, and extending the service life of key components.

[0042] Reference Figure 8 : A second hinged seat 212 is provided at one end of the push rod 21 away from the piston 11, and a ball socket is provided on the second hinged seat 212; a ball head 231 is provided at one end of the movable handle 23 close to the push rod 21, and the movable handle 23 is hinged to the ball socket of the second hinged seat 212 through the ball head 231.

[0043] As a second embodiment of the present invention, the second hinge seat 212 and the ball head 231 achieve the function of stably connecting the movable handle 23 and the push rod 21. The articulation of the ball head 231 allows the movable handle 23 to swing freely in multiple directions. Compared with the uniaxial rotation of the fixed shaft 2111, it can more flexibly adapt to the application of forces at different angles, avoid motion interference, and ensure that the push rod 21 always moves smoothly in a straight line. The ball head 231 structure can also automatically fine-tune the contact position of the hinge point. Even if there is a slight offset or assembly error when the movable handle 23 swings, it can still adaptively align, reducing the lateral stress of the push rod 21 and the risk of sticking. The spherical contact can disperse the impact force when the movable handle 23 swings, avoid rigid collisions, and make the piston 11 advance more smoothly. It is particularly suitable for feeding scenarios that require precise control of the flow rate of liquid food. The ball and socket fit between the ball head 231 and the second hinge seat 212 has a large contact area, low unit pressure, and uniform wear. It can still remain smooth after long-term use and reduce maintenance requirements. Furthermore, the articulation of the ball head 231 does not require strict centering, which reduces assembly precision requirements, facilitates quick disassembly and assembly for cleaning or replacement of parts, and improves ease of use.

[0044] Reference Figure 3 and Figure 9 : A vertical plate 14 is provided at one end of the feeding cylinder 1 away from the accommodating chamber, a pull rod 141 is slidably provided on the vertical plate 14, and the pull rod 141 is connected to one end of the push rod 21 away from the piston 11.

[0045] The present invention realizes the function of guiding the movement of the push rod 21 through the vertical plate 14 and the pull rod 141, and can stabilize the movement path of the push rod 21. After completing feeding, the medical staff can pull the pull rod 141 to drive the push rod 21 and the piston 11 to reset, so that the piston 11 returns to the starting position of the accommodating chamber. This makes it convenient for the medical staff to perform maintenance and food replenishment of the feeding cylinder 1 again. When the feeding cylinder 1 needs to be cleaned, the ball head 231 can be removed from the ball socket, and the movable handle 23 can be moved out of the feeding cylinder 1. At this time, the piston 11 can be removed from the feeding cylinder 1 through the pull rod 141, thereby facilitating the cleaning of the feeding cylinder 1 and improving the convenience of overall disassembly and assembly.

[0046] Reference Figure 7 and Figure 8 : The movable handle 23 is provided with a pull ring 232 for grasping.

[0047] The present invention facilitates the operator to rotate the movable handle 23 through the pull ring 232. When the movable handle 23 needs to be rotated close to the end of the movable handle 23, the medical staff inserts their fingers into the pull ring 232 to better rotate the movable handle 23 and improve the convenience of applying force to the movable handle 23.

[0048] Reference Figure 3 and Figure 4 : One end of the support shaft 221 away from the adjustment seat 31 is sleeved with an anti-drop cap 2211, and the movable handle 23 is located between the anti-drop cap 2211 and the adjustment seat 31.

[0049] The present invention improves the installation stability of the movable handle 23 through the anti-slip cap 2211. The setting of the anti-slip cap 2211 forms an axial limit for the movable handle 23, effectively preventing the movable handle 23 from deviating left and right or accidentally falling off the support shaft 221 during use. When the movable handle 23 swings, the anti-slip cap 2211 and the adjustment seat 31 jointly constrain the range of motion of the movable handle 23, ensuring that the movable handle 23 always swings stably along a predetermined trajectory. This structural design significantly improves the installation stability of the movable handle 23, makes the torque transmission between the movable handle 23 and the push rod 21 more reliable, and avoids the loss of transmission efficiency caused by the deviation of the movable handle 23. At the same time, the anti-slip cap 2211 is simple and practical in structure, which not only ensures operational safety, but also does not affect the normal swinging function of the movable handle 23, making the operation of the entire pushing mechanism 2 more stable and precise.

[0050] Reference Figure 1 and Figure 10 The feeding nozzle 12 is a cylindrical structure with a conical tip extending from one end, and an annular groove 121 is provided on the side of the cylindrical structure away from the tip; a convex ring 15 is provided at the front end of the feeding tube 1 to cooperate with the annular groove 121; the annular groove 121 and the convex ring 15 are connected by a threaded structure.

[0051] The present invention realizes the function of quick disassembly and assembly of the feeding nozzle 12 through the annular groove 121, the convex ring 15 and the threaded structure. The inner wall of the annular groove 121 is provided with an internal thread, and the convex ring 15 is provided with an external thread that matches the internal thread. A through hole for the circulation of liquid food is provided at the tip of the feeding nozzle 12. When the feeding nozzle 12 needs to be installed, the operator aligns the convex ring 15 of the feeding cylinder 1 with the annular groove 121 of the feeding nozzle 12, and rotates the feeding cylinder 1 to screw the convex ring 15 along the threaded structure in the annular groove 121, thereby achieving a stable connection between the feeding nozzle 12 and the feeding cylinder 1. The conical tip facilitates the precise delivery of liquid food, and the cylindrical structure ensures smooth flow of liquid food. The threaded connection between the annular groove 121 and the convex ring 15 makes the disassembly and assembly of the feeding nozzle 12 simple and quick, while ensuring the sealing of the connection to prevent leakage of liquid food. The structural design is reasonable and easy to operate, which can not only meet the hygienic requirements of feeding, but also improve feeding efficiency.

[0052] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
