Description

Technical Field

[0001] This invention relates to the field of elderly care devices, and in particular to an adaptive dispensing device and method for elderly care. Background Technology

[0002] In the field of geriatric care, medication safety and accurate drug delivery are crucial to ensuring the health of the elderly. As the population ages, some elderly people experience a decline in physical function, such as decreased hand coordination, blurred vision, or chronic diseases requiring long-term medication, making it difficult for them to independently divide pills and administer medication. Therefore, the need for assistive medication delivery devices is becoming increasingly urgent.

[0003] Understanding of the application of existing medication dispensing and administration devices for the elderly: Current methods of dispensing tablets rely on manual breaking, which can easily lead to dosage errors, especially for non-integer doses of half or quarter tablets. This makes it difficult to meet the needs of precise medication and can easily cause dosage deviations due to improper operation.

[0004] When elderly people are given medication manually, their swallowing reflex is sluggish and their hand-eye coordination is poor, making it difficult for them to put the medicine into their mouths, and sometimes the medicine may even spill.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an adaptive medication delivery device and method for elderly care to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an adaptive dispensing device and method for elderly care, which solves the problem that existing tablet dispensing relies on manual breaking of tablets, which easily leads to dosage errors. In particular, for non-integer dosages of half or quarter tablets, it is difficult to meet the needs of accurate medication. Improper operation can easily lead to dosage deviations. Furthermore, when administering medication manually, the elderly often have sluggish swallowing reflexes and poor hand coordination, making it difficult to put the medication into their mouths, and sometimes even resulting in spillage.

The shaft of motor A is threaded and located inside the delivery frame. The top of the delivery frame is slidably connected to the bottom of the rack frame. A threaded hole is provided at the front bottom of the rack frame, and the shaft of motor A is located inside the threaded hole of the rack frame.

[0009] Furthermore, a half-gear frame is rotatably connected to the upper part of the instrument frame. The lower sides of the half-gear frame mesh with the top sides of the rack frame. The middle top of the half-gear frame is fixedly connected to the middle bottom of the positioning frame. A motor B is fixedly installed at the middle right side of the positioning frame. The shaft of the motor B is fixedly connected to the right side of the bidirectional screw. The bidirectional screw is rotatably connected to the middle inside the positioning frame.

[0010] Furthermore, a platform is provided at the top center of the positioning frame, which is located above and behind the pusher. An L-shaped positioning plate is provided on the left and right sides of the inside of the positioning frame. The two positioning plates are symmetrically designed and are located on the left and right sides of the platform of the positioning frame. A rotatable adaptive gripper is provided at the front and rear ends of the upper inner side of each positioning plate.

[0011] Furthermore, a feeding rack is fixedly installed at the lower front end of the instrument rack, a guide groove is provided at the middle of the top of the feeding rack, a feeding cylinder is fixedly installed at the rear top of the feeding rack, and a feeding plate is provided at the front end of the feeding cylinder, which is slidably connected in the guide groove of the feeding rack.

[0012] Furthermore, a limiting groove is provided at the front of the inside of the feeding rack, and a limiting cylinder is fixedly installed at the front left position of the feeding rack. The limiting cylinder is provided with a limiting plate, which is located in the limiting groove of the feeding rack. When the limiting cylinder is in the extended state, the limiting plate is located at the front position of the feeding rack.

[0013] Furthermore, a receiving frame is provided at the front of the instrument rack. The upper part of the receiving frame has a funnel structure design, and the lower part has a cylindrical structure design. The receiving frame is located in front of and below the half gear frame and the positioning frame. A motor C is fixedly installed at the upper part of the receiving frame. The shaft of the motor C is equipped with a spiral frame, which is located inside the cylindrical structure of the receiving frame. A discharge hole is opened at the front of the bottom of the cylindrical structure of the receiving frame, and an optical fiber sensor is installed below the discharge hole of the receiving frame. The optical fiber sensor is located above the limiting groove of the feeding rack.

[0014] This invention also discloses a method for administering medication using an adaptive dispensing device for elderly care, comprising the following steps: 1) After the tablet enters the limiting slot of the feeding rack, the limiting cylinder is activated. The piston rod of the limiting cylinder retracts, pushing the limiting plate away from the obstruction of the front position of the limiting slot of the feeding rack. 2) Start the medication cylinder. The piston rod of the medication cylinder extends forward, pushing the medication plate to slide along the guide groove at the top of the medication holder. The medication plate pushes the tablet in the limiting groove forward. When the elderly person's mouth is at the front end of the guide groove at the top of the medication holder, the tablet is delivered to the elderly person's mouth, completing the medication feeding. 3) After the medication is fed, the piston rods of the medication feeding cylinder and the limit cylinder retract, driving the medication feeding plate and the limit plate to reset, waiting for the next medication feeding operation, and ensuring that the inside of the limit groove of the medication feeding rack is clean.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The device, through the combination design of the main cutter and the auxiliary cutter, can flexibly achieve precise division of non-integer doses such as half tablets and quarter tablets. When a half tablet dose is needed, the auxiliary cutter is adjusted upward by the screw, and only the main cutter acts on the tablet. When a quarter tablet dose is needed, the auxiliary cutter is adjusted downward to be flush with the main cutter, and the two cutters cut synchronously, avoiding dosage deviation caused by manual tablet breaking. It is especially suitable for elderly patients with chronic diseases who are sensitive to medication dosage, ensuring medication safety from the source.

[0016] 2. The L-shaped positioning plate on the positioning frame works in conjunction with the rotatable adaptive gripper to automatically adjust the clamping force and angle according to the size of the tablet, centering and fixing the tablet in the middle of the table. Even when faced with tablets of different diameters and thicknesses, it can ensure that the tablets do not shift during cutting, further improving the accuracy of dispensing and solving the problems of easy slippage and inaccurate cutting position when manually fixing tablets.

[0017] 3. Through the transmission cooperation of motor A, rack and pinion frame and half gear frame, the dispensing tablets can automatically complete the transfer process of "positioning frame tilting and sliding down to receiving frame", without the need for manual contact or transfer of tablets. This avoids the problems of tablets falling and contamination that may occur during manual transfer, and reduces the workload of caregivers. It is especially suitable for nursing homes, homes and other scenarios that require high-frequency medication.

[0018] 4. The receiving rack adopts a funnel structure to receive tablets. With the rotation and pushing of the internal spiral frame, the tablets can be conveyed downward in an orderly and stable manner. The fiber optic sensor below can detect the discharge situation in real time. When the set dose of tablets is detected to enter the feeding rack, the system will immediately stop the motor C to avoid overfeeding or underfeeding. This ensures that the dosage of each feeding is completely matched with the doctor's order and eliminates the possibility of overdosing or underdosing due to manual counting errors.

[0019] 5. The guide groove of the pill feeder works in conjunction with the feeding plate to accurately push the pills to the elderly person's mouth along a fixed trajectory, eliminating the need for the elderly person to reach out or bend down to take the medicine. This is suitable for elderly people with decreased hand coordination and blurred vision. At the same time, the limiting plate can prevent the pills from slipping off before feeding and automatically retracts to avoid spilling the pills during feeding, ensuring the stability of the feeding process.

[0020] 6. From tablet positioning, dispensing, delivery to medication administration, no complicated manual operations are required throughout the entire process. Nursing staff only need to complete the initial tablet placement and equipment startup to achieve automated medication administration, reducing the professional skill requirements for nursing staff. It is especially suitable for non-professional nursing staff in the home, thus improving the universality of the device. Attached Figure Description

The bidirectional screw 107 is rotatably connected to the middle inside the positioning frame 105.

[0030] The positioning frame 105 has a platform at the top center, which is located above and behind the pusher 202. The positioning frame 105 has an L-shaped positioning plate 108 on its left and right sides. The two positioning plates 108 are symmetrically designed and are located on the left and right sides of the platform. Each positioning plate 108 has a rotatable adaptive gripper 109 at both the front and rear ends of its inner upper side.

[0031] Among them, a feeding rack 3 is fixedly installed at the lower front end of the instrument rack 1. A guide groove is opened at the middle of the top of the feeding rack 3. A feeding cylinder 301 is fixedly installed at the rear top of the feeding rack 3. A feeding plate 302 is provided at the front end of the feeding cylinder 301. The feeding plate 302 is slidably connected in the guide groove of the feeding rack 3.

[0032] The medicine feeding rack 3 has a limiting groove at the front of its interior, and a limiting cylinder 303 is fixedly installed at the front left of the medicine feeding rack 3. The limiting cylinder 303 is equipped with a limiting plate 304, which is located in the limiting groove of the medicine feeding rack 3. When the limiting cylinder 303 is in the extended state, the limiting plate 304 is located at the front of the medicine feeding rack 3.

[0033] The instrument rack 1 has a receiving frame 4 located at the front of its interior. The receiving frame 4 has a funnel-shaped upper structure and a cylindrical lower structure. The receiving frame 4 is located in front of and below the half-gear frame 104 and the positioning frame 105. A motor C401 is fixedly installed at the upper interior of the receiving frame 4. The shaft of the motor C401 is equipped with a spiral frame 402, which is located inside the cylindrical structure of the receiving frame 4.

A fiber optic sensor 403 is installed below the discharge hole of the receiving frame 4, and the fiber optic sensor 403 is located above the limiting groove of the feeding rack 3.

[0034] When using: Place the tablet on the shelf at the top of the positioning frame 105, start the motor B106, the motor B106 drives the bidirectional screw 107 to rotate, the bidirectional screw 107 drives the two L-shaped positioning plates 108 on both sides to slide towards each other along the inside of the positioning frame 105 until the two adaptive grippers 109 on the inner side of the two positioning plates 108 are in contact with and tightened on the periphery of the tablet. At this time, the tablet will be centered and fixed in the middle position of the shelf at the top of the positioning frame 105 to prevent the tablet from shifting during the dispensing process.

[0035] Tablet dispensing operation When it is necessary to divide the dose into half tablets, rotate the screws 207 on both sides of the top of the control frame 205. The screws 207 drive the auxiliary cutter 208 at the bottom to slide upward along the slide groove of the lifting frame 204. At this time, the bottom position of the main cutter 206 is lower than the bottom position of the two auxiliary cutters 208.

[0036] When a quarter-tablet needs to be divided, the screws 207 on both sides of the top of the control frame 205 are rotated in the opposite direction. The screws 207 drive the auxiliary cutter 208 at the bottom to slide down along the slide groove of the lifting frame 204 until the bottom of the main cutter 206 is level with the bottom of the two auxiliary cutters 208.

[0037] Start the dispensing cylinder 203. The piston rod of the dispensing cylinder 203 extends downward, pushing the control frame 205 and the lifting frame 204 to slide down along the inside of the mating frame 2. The lifting frame 204 drives the main cutter 206 and the adjusted auxiliary cutter 208 to move down synchronously, cutting the tablets fixed on the positioning frame 105 and completing the dispensing operation. After the dispensing is completed, the piston rod of the dispensing cylinder 203 retracts, which drives the lifting frame 204, the main cutter 206 and the auxiliary cutter 208 to reset. At this time, the push cylinder 201 is activated to extend and drive the pusher 202 to move forward. The pusher 202 can then push the pills on the top shelf of the positioning frame 105 forward a certain distance.

[0038] Delivery of split tablets: When motor A102 is started, the threaded shaft of motor A102 rotates inside the advance frame 101. Since the bottom of the rack frame 103 has a threaded hole that matches the shaft of motor A102, the shaft of motor A102 drives the rack frame 103 to slide back and forth along the top of the advance frame 101.

[0039] When the rack frame 103 slides backward, its top two sides mesh with the lower two sides of the half gear frame 104, driving the half gear frame 104 to rotate around the rotation connection point inside the instrument frame 1. The positioning frame 105 on the top of the half gear frame 104 rotates synchronously with the half gear frame 104 to an inclined state, so that the divided tablets slide from the positioning frame 105 platform into the receiving frame 4 below.

[0040] Drug collection and loading: Start the motor C401 inside the receiving frame 4. The motor C401 drives the screw frame 402 to rotate inside the cylindrical structure of the receiving frame 4. The screw frame 402 pushes the tablets downward along the cylindrical structure. Finally, the tablets are discharged from the discharge hole at the bottom front of the receiving frame 4. After the fiber optic sensor 403 below the discharge hole of the receiving rack 4 detects the tablet being discharged, it sends a signal back to the system to ensure that the tablet enters accurately. The fiber optic sensor 403 stops the motor C401 based on the dose feedback from the discharge hole of the receiving rack 4. At this time, the dose entering the limit groove of the feeding rack 3 will be confirmed, and the medication inside the receiving rack 4 will be prevented from continuing to be delivered into the limit groove of the feeding rack 3.

[0041] Medication administration procedure: After the tablet enters the limiting groove of the feeding rack 3, the limiting cylinder 303 is activated. The piston rod of the limiting cylinder 303 retracts, pushing the limiting plate 304 to disengage from the position in front of the limiting groove of the feeding rack 3.

[0042] Start the medication cylinder 301. The piston rod of the medication cylinder 301 extends forward and pushes the medication plate 302 to slide along the guide groove at the top of the medication rack 3. The medication plate 302 pushes the tablet in the limiting groove forward. The elderly person's mouth is located at the front end of the guide groove at the top of the medication rack 3, and the tablet is delivered to the elderly person's mouth to complete the medication feeding. After the medication is fed, the piston rods of the medication feeding cylinder 301 and the limit cylinder 303 retract, causing the medication feeding plate 302 and the limit plate 304 to reset, waiting for the next medication feeding operation, and ensuring that the inside of the limit groove of the medication feeding rack 3 is clean.
