Description

Technical Field

[0001] The invention relates to the technical field of liquid food feeding devices, in particular to a liquid food feeding device for elderly care, which can adjust feeding components to meet the use of two liquid food feeding methods: nasogastric feeding and oral feeding. Background Art

[0002] Liquid feeding is a way of feeding in which food is made into liquid form or easily dissolved into liquid. It is suitable for patients who cannot chew or swallow solid food, such as patients with high fever, oral, cheek surgery, gastrointestinal surgery, etc. The gastrointestinal system of the elderly is more fragile than that of the young. After falling ill, they need food that is easier to digest and absorb. There are two ways to feed liquid food: nasogastric feeding and oral feeding. When the elderly are in poor physical condition and cannot chew and swallow, they need to use nasogastric feeding to inject liquid food into the esophagus. The liquid food required for nasogastric feeding requires high fineness, but liquid food cannot be eaten for a long time. Long-term consumption of liquid food will increase the burden on the stomach, reduce stomach function, reduce chewing ability and unbalanced nutrition. When the physical condition of the elderly improves, they can swallow but have difficulty in moving their limbs. At this time, they can take it orally. Oral liquid food can use semi-liquid food containing food particles, which has a higher nutritional content and is beneficial to the health of the elderly. The existing liquid food feeding device can only adopt one liquid food feeding method, but the physical condition of the elderly is changing, and different liquid food feeding devices need to be purchased during the nursing period, which increases the use cost.

An elastic member 3 416 is fixedly connected to the residue groove 415, and an arc block 417 is fixedly connected to the other end of the elastic member 3 416. When the arc block 417 is hit, the elastic member 3 416 will shrink, driving the arc block 417 to vibrate, hit the filter plate 410, and vibrate the food residue on it into the residue groove 415.

[0021] Among them, an output port 216 is opened on one side of the lower container 21, and the output port 216 is fixedly connected to a micro pump 31. The top of the micro pump 31 is fixedly connected to a delivery pipe 32, and the other end of the delivery pipe 32 is fixedly connected to a mounting frame 33. A connecting block 34 is fixedly connected inside the mounting frame 33. A T-slot 35 is opened inside the connecting block 34, and a sphere 36 is arranged inside the T-slot 35. An L-slot is opened inside the sphere 36. The internal spaces of the delivery pipe 32, the connecting block 34 and the sphere 36 are connected. The micro pump 31 pumps the liquid food into the connecting block 34 through the delivery pipe 32, and then outputs it through the sphere 36, the pipeline 37 and the connecting block 2 38.

[0022] The two sides of the connection block 1 34 are symmetrically fixedly connected with pipes 37 , and the other end of the pipe 37 is fixedly connected with a connection block 2 38 . A channel 39 is opened in the connection block 2 38 , and liquid food can enter the hose 310 or the injection port 312 through the channel 39 .

[0023] Among them, one of the connection blocks 2 38 has a hose 310 fixedly connected to one side, and the hose 310, the connection block 2 38 and the internal space of the pipeline 37 are connected. The other end of the hose 310 is fixedly connected to a spoon 311, and the liquid food flows out through the hose 310 and enters the spoon 311, which is convenient for the nursing staff to feed. Another connection block 2 38 has an injection port 312 fixedly connected to one side, and the injection port 312 can cooperate with a nasogastric tube to directly deliver the liquid food to the esophagus.

[0024] Among them, the shell 1 is provided with a handle 314 rotatably connected on the same side where the conveying component 3 is provided, and a rotating shaft 313 is fixedly connected to one side of the handle 314, and the other end of the rotating shaft 313 penetrates the shell 1 and the connecting block 1 34 and is fixedly connected to the ball 36, and the rotating shaft 313 is rotatably connected to the shell 1, and a gear 2 315 is fixedly connected to the rotating shaft 313, and the gear 2 315 is located in the shell 1, and the gear 2 315 is meshed with the gear 1 414. An arrow 317 is provided on the handle 314, and the direction of the arrow 317 is the same as the opening direction of the L-shaped groove opened inside the ball 36. Rotating the handle 314 can drive the ball 36 to rotate in the connecting block 1 34 to change the flow direction of the liquid food, and the arrow 317 on the handle 314 can assist in confirming the working mode of the device.

[0025] Embodiment 1: Figure 1-11As shown, in this embodiment, when the liquid food is taken orally, the handle 314 is rotated to drive the ball 36 in the connecting block 1 34 to rotate, and the outlet of the L-shaped groove in the ball 36 is directed toward the channel 39 in the direction of the hose 310. When the handle 314 is rotated, it will rotate together with the gear 2 315. Since the gear 2 315 is meshed with the gear 1 414, the gear 1 414 is driven to rotate. The gear 1 414 rotates together with the screw rod 413 and cooperates with the threaded sleeve 412 to drive the threaded sleeve 412 and the rack 411 to move along the slide groove 43 toward the upper container 25. The rack 411 cooperates with the tooth grooves 46 on the connecting rings 45 on both sides to drive the pair of connecting rings 45 to rotate, so that the semicircular holes on the pair of connecting rings 45 are moved. The filter plate 410 is opened, and at this time the filter plate 410 is located outside the storage component 2. The liquid food crushed in the blender is poured into the device from above the upper container 25, and the liquid food will directly enter the lower container 21. The micro pump 31 is started, and the liquid food is pumped from the lower container 21 to the inside of the installation frame 33 through the delivery pipe 32, and enters the pipeline 37 through the T-slot 35 in the connecting block 1 34 and the L-slot in the sphere 36, and enters the hose 310 through the connecting block 2 38. A rubber spoon 311 is connected to the outlet of the hose 310. After the liquid food flows out of the hose 310, it will stay in the spoon 311. The output rate and amount of the liquid food are intermittently controlled by the control panel 5, and the caregiver can feed the elderly with the spoon 311.

[0026] It should be noted that an arrow 317 is engraved on the handle 314, and the direction of the arrow 317 is consistent with the direction of the outlet of the L-shaped groove in the sphere 36. The direction indicated by the arrow 317 is used to determine the way the liquid food flows out at this time. A pair of limit bars 316 are fixedly connected to the same side of the outer shell 1 and the handle 314. The limit bars 316 are horizontally symmetrically arranged on both sides of the handle 314 to limit the rotation angle of the handle 314.

[0027] When liquid food is needed to be fed through nasogastric feeding, the liquid food required is of high fineness. The liquid food produced by the blender contains food particles and vegetable fibers, which need to be further filtered. The handle 314 is reversed, and the reversed handle 314 drives the ball 36 in the connecting block 1 34 to rotate, and the outlet of the L-shaped groove in the ball 36 is directed toward the channel 39 in the direction of the injection interface 312. When the handle 314 is rotated, it will rotate together with the gear 2 315, and the gear 2 315 rotates and meshes with the gear 1 414, driving the gear 1 414 to rotate. The gear 1 414 rotates together with the screw 413 and cooperates with the threaded sleeve 412 to drive the threaded sleeve 412 and the rack 411 along the slide groove 43 toward the screw 413. The rack 411 cooperates with the tooth grooves 46 on the connecting rings 45 on both sides to drive the pair of connecting rings 45 to rotate, so that the semicircular filter plate 410 on the connecting ring 45 rotates around the central axis 42 toward the lower container 21. During the rotation, one side of the filter plate 410 will contact the surface of the collar 23. The outer ring surface of the collar 23 is an arc surface. After being squeezed by the filter plate 410, it will move downward. The collar 23 partially retracts into the groove 22 and compresses the elastic member 24. The filter plate 410 continues to rotate to between the upper container 25 and the lower container 21. When the pair of filter plates 410 are rotated to between the upper container 25 and the lower container 21, they are combined into a circular filter plate 410.

[0028] Pour the liquid food into the upper container 25, and the liquid food enters the lower container 21 after being filtered by the filter plate 410. Some unbroken particles in the liquid food will be left on the filter plate 410. Cover the top of the upper container 25 with the top cover 27, so that the limit block 215 enters the limit groove 214. Rotate the top cover 27 to make the limit block 215 slide in the limit groove 214 to limit the vertical freedom of the top cover 27. Start the electric telescopic rod 28, and its output end drives the hollow rod 29 to move downward, thereby driving the lower pressing plate 213 and the upper pressing plate 212 to move downward. The lower pressing plate 213 will first contact the filter plate 410, and after being restricted by the filter plate 410, it cannot Continue to move downward. At this time, the hollow rod 29 continues to drive the upper pressure plate 212 to move downward, the telescopic rod 211 will retract into the hollow rod 29, and the elastic member 210 will be compressed until the upper pressure plate 212 and the lower pressure plate 213 are in contact with the filter plate 410, squeezing the particles on the filter plate 410, so that the soup inside the particles flows into the lower container 21. When all the liquid food enters the lower container 21, the micro pump 31 is started to draw the liquid food into the delivery tube 32. The liquid food passes through the delivery tube 32, the connecting block 1 34, the pipeline 37 and the connecting block 2 38, and finally leaves the device from the injection interface 312. The injection interface 312 will be connected to the nasogastric tube of the elderly in advance.

[0029] After nasogastric feeding is completed, the handle 314 can be rotated again to the direction of the arrow 317 toward the hose 310. During this process, the filter plate 410 will rotate around the central axis 42 and move out from between the upper container 25 and the lower container 21. The elastic member 1 24 in the groove 1 22 will recover and push the ring 23 into the groove 2 26 at the bottom of the upper container 25 again, closing the space between the upper container 25 and the lower container 21. As the handle 314 rotates, the rack 411 continues to drive the connecting ring 45 and the filter plate 410 to rotate, and the bevel gear 49 on the sleeve 48 will mesh with the toothed disc 44. , causing the filter plate 410 to rotate around the column 47. When the arrow 317 on the handle 314 points horizontally to the hose 310, the filter plate 410 will rotate around the central axis 42 to the top of the residue groove 415, and rotate around the column 47 to an inclined state. The upper end surface of the filter plate 410 will collide with the arc block 417, causing the elastic member three 416 to contract. After the elastic member three 416 contracts, it will recover and cause the arc block 417 to vibrate briefly, colliding with the filter plate 410 for multiple times, loosening the food residue on the filter plate 410, and the loosened food residue will fall into the residue groove 415.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
