Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Please see Figures 1-5 This utility model provides a technical solution: a liquid food feeding device for the digestive department, including a storage container 110, a sealing cap 120 threadedly installed at the top of the storage container 110, a U-shaped bracket 130 fixedly installed at the top of the sealing cap 120, a threaded rod 131 rotatably installed at the top of the inner wall of the bracket 130, a motor 132 installed at the top of the threaded rod 131, a threaded sleeve rod 133 threadedly connected to the bottom of the threaded rod 131, a piston 134 fixedly installed at the bottom of the threaded sleeve rod 133 through the sealing cap 120, and the piston 134 slidably connected to the inner wall of the storage container 110. A groove is provided at the bottom of the storage container 110, and a discharge port is provided in the groove. A threaded ring 111 is fixedly installed on the discharge port, and an adapter component is threadedly installed on the threaded ring 111.
[0029] In some specific implementations, a horizontal plate 135 is fixedly installed on the outer top of the threaded rod 131. Sliding grooves are symmetrically arranged on both sides of the inner wall of the bracket 130. A guide rod 136 is fixedly installed on the inner wall of the sliding groove. The horizontal plate 135 is slidably installed on the guide rod 136, and the horizontal plate 135 is slidably connected to the inner wall of the sliding groove. The horizontal plate 135 cooperates with the guide rod 136 to stabilize and guide the threaded rod 131 when it rotates. This prevents the threaded rod 131 from shaking or shifting during rotation, ensuring that the threaded sleeve rod 133 moves smoothly up and down, thereby ensuring that the piston 134 slides stably within the receiving tank 110. This allows the liquid food to be evenly and stably pressurized and flow smoothly out of the outlet, improving the stability of liquid food feeding.
[0030] In some specific implementations, a cavity is provided inside the support 130, and a motor 132 is fixedly installed inside the cavity. The output end of the motor 132 passes through the support 130 and is fixedly connected to the top of the threaded rod 131. A controller is installed on the outside of the sealing cover 120, and the controller is electrically connected to the motor 132. The controller on the outside of the sealing cover 120 is convenient for medical staff to operate, and can directly control the start, stop and speed of the motor 132, thereby flexibly adjusting the moving speed of the piston 134 and precisely controlling the extrusion volume and flow rate of the liquid food to meet the feeding needs of different patients.
[0031] In some specific implementation schemes, battery compartments are symmetrically arranged at the top of the bracket 130, and a top cover is snapped onto the top of the battery compartment. A battery pack is installed inside the battery compartment, and the battery pack is electrically connected to the motor 132.
[0032] In some specific implementations, the adapter components include a sealing cap 112 and a connecting tube 113. One end of the inner wall of both the sealing cap 112 and the connecting tube 113 is provided with threads that match the threaded ring 111. The sealing cap 112 and the connecting tube 113 are threaded onto the outside of the threaded ring 111. The battery compartment design provides an independent power source for the motor 132, allowing the feeding device to be used without relying on an external power source. This eliminates the constraints of a power cord and facilitates operation in wards, mobile nursing settings, or other locations without power outlets, improving the portability and flexibility of the device. Simultaneously, the snap-on top cover facilitates battery pack replacement, ensuring continuous and stable operation of the device.
[0033] In some specific implementations, a handle 114 is fixedly installed on the outside of the storage container 110. This allows the user to operate the container more easily and stably, whether pouring liquid food, adjusting the position of the storage container 110, or using it in conjunction with a support structure. Especially when feeding patients with limited mobility, the handle 114 helps medical staff or family members better control the storage container 110, improving the safety and convenience of the feeding process.
[0034] Please see Figure 5 and Figure 6 A support ring 140 is rotatably mounted on the outside of the sealing cover 120. An L-shaped frame 141 is fixedly mounted on the outside of the support ring 140. An L-shaped support plate 142 is slidably mounted on the L-shaped frame 141. A fixing component that mates with the support plate 142 is installed inside the L-shaped frame 141. A strip hole matching the support plate 142 is provided on the L-shaped frame 141. The L-shaped frame 141 is slidably connected to the inner wall of the strip hole. A protective pad is installed on the outside of the support plate 142. A limiting ring 143 is fixedly mounted on the inner wall of the support ring 140. A limiting groove matching the limiting ring 143 is provided on the outside of the sealing cover 120. The limiting ring 143 is slidably connected to the inner wall of the limiting groove. The cross-section of the limiting ring 143 is T-shaped.
[0035] In some specific implementations, the fixing assembly includes a pressure plate 144, a plug rod, and a spring 145. An L-shaped frame 141 has a cavity, with the pressure plate 144 slidably mounted on the inner wall of the cavity. Springs 145 are symmetrically fixed between the top of the pressure plate 144 and the top of the inner wall of the cavity. Plug rods are symmetrically fixed at the bottom of the pressure plate 144, with the bottom end of the plug rod penetrating one side of the cavity and inserting into a support plate 142. A pull block 146 is fixedly mounted on the top of the pressure plate 144, with the top end of the pull block 146 slidably penetrating the L-shaped frame 141 and extending to the outside. The support plate 142 has multiple insertion holes that match the plug rods. This fixing assembly design makes the position adjustment of the support plate 142 convenient and secure. By pulling the pull block 146, the plug rod can be easily disengaged from the insertion holes on the support plate 142, thereby freely adjusting the position of the support plate 142. After adjustment, release the pull block 146. The elastic force of the spring 145 will cause the plug rod to re-insert into the corresponding socket, firmly fixing the support plate 142. The design of multiple sockets can meet the adjustment needs of different heights and angles, enhancing the flexibility and adaptability of the support structure.
[0036] Working principle: In use, first seal the outlet by cooperating with the sealing cap 112 and the threaded ring 111, then pour the liquid food into the storage container 110, and cover it with the sealing cap 120 to complete the storage. When it is time to feed, rotate the sealing cap 112 to remove it and replace it with the connecting tube 113. Pull the pull block 146 to move the insertion rod to the insertion hole through the pressure plate 144. Pull the support plate 142 to the appropriate support position and then release the pull block 146. At this time, the tension of the spring 145 will move the pressure plate 144 back to the insertion hole to fix the insertion rod. Hold the handle 114 and place the storage container 110 horizontally on one side of the support plate 142 for support. The connecting tube 113 can be connected to the feeding tube or placed directly into the mouth. Start the motor 132 to drive the threaded rod 131 to rotate. The rotation of the threaded rod 131 will drive the threaded sleeve rod 133 to move down and drive the piston 134 to move. At this time, the liquid food will be pressurized and flow out from the outlet.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
