Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multifunctional intelligent medicine feeding device for patients used in clinical nursing. Background Art

[0002] In the healthcare field, medication management for patients remains a critical and complex task in clinical care. While patients who are able to take medication independently can complete the process under the guidance of medical staff, there is still the potential risk of forgetting to take medication or taking the wrong dosage. For those who are unable to take medication independently, such as those in coma, infants, the frail elderly with dysphagia, and those with neurological disorders that impair limb coordination and cognitive function and prevent them from cooperating with medication, medication feeding becomes extremely challenging.

[0003] The traditional manual medication feeding method relies on the high concentration and sense of responsibility of the nursing staff. According to the doctor's instructions, the nursing staff needs to manually select the medicine from the medicine box, carefully check the type and dosage of the medicine, and then use feeding tools such as feeding spoons and syringes to deliver the medicine to the patient's mouth or administer the medicine through auxiliary methods such as nasogastric tubes. This process not only requires nursing staff to spend a lot of time and energy, but also greatly increases the workload when facing multiple patients who need to be fed. At the same time, manual operation is easily interfered with by various factors, such as nursing staff fatigue, distraction, or momentary memory deviations in busy nursing work, which may cause problems such as drug confusion and dosage errors. In severe cases, it may even pose a threat to the life and health of patients.

[0004] From a technical perspective, while some basic medication-feeding aids existed in the past, they were limited in functionality and lacked intelligence. Ordinary medicine storage boxes only served to simply sort and store medications, lacking features like automatic reminders, precise metering, and interaction with hospital information systems. Traditional medication spoons, syringes, and other tools struggled to precisely control dosages for medications in various forms (e.g., tablets, capsules, liquids, and suspensions), and they were ineffective in addressing drug absorption challenges for patients with dysphagia.

The bottom of the operating table 6 is fixedly connected to the second rotary workbench 5, the bottom of the second rotary workbench 5 is fixedly connected to the inner frame 4, the outer wall of the inner frame 4 is slidably connected to the outer shell 3, the bottom of the outer shell 3 is fixedly connected to the first rotary workbench 2, the bottom of the first rotary workbench 2 is fixedly connected to the chassis 1, and both ends of the bottom of the chassis 1 are fixedly connected to a protective shell 7, and hub motors 20 are provided on both sides of the protective shell 7. The outer wall of the hub motor 20 is provided with a tire 8.

[0020] The electric rotary table 17 can rotate 360 degrees horizontally, driving the base 21 and its attached upper arm 23, lower arm 25, and end effector 26 to rotate and adjust the overall working position. The first brake motor 22 and the second brake motor 24 respectively control the swing of the upper arm 23 and lower arm 25. Through precise motor control, the end effector 26 can be accurately moved to the target position, whether reaching a patient at the bedside or aiming at the medicine storage box 15 on the storage rack 13.

The output end of the third brake motor 27 rotates, driving the rubber wheel 49. The interaction between the rubber wheel 49 and the groove 30 drives the first and second adjustment dials 31 and 44 in the feeding and access components to rotate, inserting the needle 40 into the sealing ring 47 to draw water from the water tank 46.

[0021] Please see the attached Figure 4 -Attached Figure 5 The medicine feeding assembly includes a first adjusting turntable 31, which is rotatably connected to the outer wall of the C-shaped block 34. A clamp 38 is penetrated and slidably connected to the middle side of the outer wall of the first adjusting turntable 31, and a syringe 40 is slidably connected to one end of the clamp 38.

[0022] For liquid medication, the syringe 40 is first adjusted to a suitable position so that it can slide along the first adjustment dial 31 and be inserted into the liquid medicine bottle to extract the medication. The syringe 40 is then fixed again. The first adjustment dial 31 rotates, driving the syringe 40 toward the patient. The push rod motor 35 pushes the clamp 38, which drives the syringe piston, slowly injecting the medication into the latex spoon 43, and then feeding the medication to the patient. Alternatively, a nasogastric tube can be connected for auxiliary feeding as needed.

[0023] Please see the attached Figure 5 The inner wall of the first slide groove 37 is slidably connected to the limit rod 39, one side of the limit rod 39 is fixedly connected to the limit ring 41, the inner wall of the limit ring 41 is slidably connected to the slide rod 42, and the latex spoon 43 is fixedly connected between the slide rods 42, and the latex spoon 43 is penetrated and slidably connected to the syringe 40.

[0024] For smaller tablets, a latex spoon 43 can be used for feeding. By moving the limit rod 39 in the first slide groove 37, the relative position of the latex spoon 43 and the syringe 40 can be adjusted so that the latex spoon 43 is aligned with the tablet. The syringe 40 is fixed by the clamp 38 to assist in controlling the movement of the latex spoon 43. After the latex spoon 43 scoops up the tablet, the tablet is fed to the patient through the rotation of the first adjustment dial 31 and the movement of the robotic arm. Then, water is sent to the latex spoon 43 through the syringe 40, and the water is sent to the patient's mouth through the latex spoon 43 to help the patient swallow.

[0025] Please see the attached Figure 6 A pneumatic finger 32 is slidably connected to the other side of the outer wall of the first adjusting dial 31, and a first limit block 33 is fixedly connected to both sides of the outer wall of the pneumatic finger 32, and the first limit block 33 is slidably connected to the inner wall of the first adjusting dial 31.

[0026] If the medicine is larger particles or irregular shapes, the pneumatic finger 32 is started (the pneumatic finger 32 can be provided with a disposable finger sleeve as needed). Under the guidance of the first limit block 33, the pneumatic finger 32 slides out along the first adjustment dial 31 to accurately clamp the medicine. Subsequently, the first adjustment dial 31 is driven by the third brake motor 27 and rotates through the cooperation of the rubber wheel 49 and the groove 30 to rotate the pneumatic finger 32 that clamps the medicine to face the patient. Then the upper arm 23 and the lower arm 25 move in coordination to deliver the medicine to the patient's mouth.

[0027] Please see the attached Figure 7 The storage and retrieval component includes a second adjusting turntable 44, which is rotatably connected to the outer wall of the C-shaped block 34. A water trough 46 is penetrated and opened at the top of the outer wall of the second adjusting turntable 44, and a sealing ring 47 is penetrated and provided at one end of the water trough 46. A cover plate 18 is provided on the top of the water trough 46, and a water inlet 19 is penetrated and slidably connected to the top of the cover plate 18.

[0028] When it is necessary to take medicine, the second adjusting dial 44 rotates to move the medicine storage box 15 to a position close to the opposite side of the end effector 26, and the push rod motor 35 pushes the electromagnet to extend. The electromagnet attracts the magnet 16 at one end of the medicine storage box 15 and pulls the medicine storage box 15 out of the limiting groove 14 of the placement rack 13. Then, the second adjusting dial 44 rotates again to rotate the medicine storage box 15 to a suitable angle to facilitate the feeding component to take out the medicine from it. The rubber sponge 45 set at one end of the medicine storage box 15 can seal and protect the medicine to prevent the medicine from getting damp or contaminated.

[0029] Please see the attached Figure 3The top of the operating table 6 is penetrated and provided with an atomizer 9, the output end of the atomizer 9 is slidably connected to an atomizer tube 10, one end of the atomizer tube 10 is penetrated and slidably connected to an atomizer cup 11, the top of the atomizer cup 11 is fixedly connected with a handle 12, and the atomizer cup 11 is penetrated and slidably connected to the top of the operating table 6.

[0030] When the patient needs nebulization, the pneumatic finger 32 is started. Under the guidance of the first limit block 33, the pneumatic finger 32 slides out along the first adjustment dial 31 to turn on the nebulizer 9, and then the handle 12 on the nebulizer cup 11 is accurately clamped to take out the nebulizer cup 11. The pneumatic finger 32 holding the nebulizer cup 11 is rotated to face the patient, and the nebulizer cup 11 is aligned with the patient's mouth and nose. The patient inhales the nebulized medicine into the body through breathing, thereby achieving efficient respiratory tract drug administration, which is particularly suitable for the treatment of patients with respiratory diseases.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
