Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a reminder device for patients with Alzheimer's disease. Background Technique

[0002] Alzheimer's disease (alias: senile dementia, abbreviation: AD) is a progressive neurodegenerative disease with insidious onset. Clinically, it is characterized by comprehensive dementia manifestations such as memory impairment, aphasia, apraxia, agnosia, visuospatial skill impairment, executive function disorder, and personality and behavioral changes, and the cause has not been clarified so far.

[0003] The number of patients with Alzheimer's disease is continuously increasing nowadays. With the aggravation of the aging of the world's population, the prevalence of Alzheimer's disease has increased. Some patients will have recent memory decline, often forget what they need to do in daily life, and more seriously, they may even forget their closest people and show aphasia, apraxia, and agnosia.

[0004] At present, the current medical technology cannot cure Alzheimer's disease. Therefore, Alzheimer's disease reminder devices are often used to relieve patients' cognitive impairment and help patients with Alzheimer's disease relieve mild and moderate cognitive impairment. Existing reminder devices are mostly items placed separately. When in use, they are easily accidentally dropped and damaged by knocking, or accidentally moved to a remote and narrow position, which is not conducive to patients receiving reminder signals. Such reminder devices only emit voice reminder signals, the reminder information is relatively monotonous, and patients may not easily understand it. At the same time, patient feedback information cannot be obtained, and the effect of relieving the disorder of patients with Alzheimer's disease is limited.

[0005] For example, Patent 202321470746.X discloses an Alzheimer's disease reminder device, which includes a reminder device body. Buffer cylinders are arranged at the four end corners of the reminder device body, and a limiting plate is slidably connected inside the buffer cylinder. A buffer rod is welded on the outer wall of one side of the limiting plate. The structure of this device can play a role in buffering and protecting the reminder device, but it can only emit voice reminder signals, has a single function and a large volume, and is not convenient to use. Content of the Utility Model

[0006] The purpose of the utility model is to provide a reminder device for patients with Alzheimer's disease, which combines various reminder mechanisms and a display module to enrich the content of reminder information, is more conducive to patients' understanding, and has a better guiding effect on patients.

[0007] To achieve the above purpose, the basic scheme of the utility model is: a reminder device for patients with Alzheimer's disease, including a wearing part, a medication reminder mechanism, a meal reminder mechanism, a sleep reminder mechanism, a going-out reminder mechanism, and a display module;

[0008] The wearable device is provided with a clock and a timer. The clock is connected to the timer. A plurality of reminder times are set in the timer. The output end of the timer is connected to the control ends of a medicine reminder mechanism, a meal reminder mechanism, a sleep reminder mechanism, and a going-out reminder mechanism;

[0009] The display module is arranged on the wearable device or installed on the indoor wall. Preset videos corresponding to the operations of the medicine reminder mechanism, the meal reminder mechanism, the sleep reminder mechanism, and the going-out reminder mechanism are arranged in the display module. The corresponding video playback control end of the display module is connected to the output end of the timer.

[0010] The working principle and beneficial effects of this basic solution are as follows: In this technical solution, timing is carried out through the clock and timer on the wearable device, and control signals are sent to each reminder mechanism at the preset reminder times to control each reminder mechanism to start and send reminder signals. Moreover, the wearable device is directly worn on the patient, and compared with a separately placed device, the installation is more stable.

[0011] When the preset reminder time arrives, the timer also sends a control signal to the display module to control the display module to display the preset video corresponding to the operation of the reminder mechanism. The patient can watch the video to understand the operations required of himself / herself. The information acquisition is more intuitive, more conducive to the patient's understanding, and the guiding effect on the patient is better.

[0012] Further, the medicine reminder mechanism includes a medicine placement box, a medicine delivery tube, a photoelectric sensor, a receiving tray, a counter, a first pressure comparator, and a medicine reminder device;

[0013] A plurality of compartments for placing different medicines are arranged in the medicine placement box. The medicines of corresponding types are arranged in sequence from bottom to top in the compartments, and there is only one pill in each row of the medicines arranged in the compartments. An electric valve is arranged at the bottom of the compartment;

[0014] The medicine delivery tubes correspond to the compartments one by one. The top of the medicine delivery tube is communicated with the bottom of the corresponding compartment. The photoelectric sensor is arranged on the inner wall of the medicine delivery tube near the compartment. The output end of the photoelectric sensor is connected to the counter. The counter is connected to the first input end of the quantity comparator through an analog-to-digital conversion module. A quantity threshold memory is connected to the second input end of the quantity comparator. The output end of the quantity comparator is connected to the control end of the electric valve;

[0015] The receiving tray is arranged at the bottom of the medicine delivery tube. A weighing device is connected to the bottom of the receiving tray. The output end of the weighing device is connected to the first input end of the first pressure comparator. A first pressure threshold comparator is connected to the second input end of the first pressure comparator;

[0016] The medicine reminder device is installed on the medicine placement box. The output end of the first pressure comparator is connected to the control end of the medicine reminder device.

[0017] When the clock reaches the medication reminder time, the timer sends a control signal to the medication reminder mechanism, and the medication reminder mechanism is activated. The electric valve opens, and the medication in the medication placement box compartment falls from the bottom of the compartment into the medicine delivery tube. At this time, the photoelectric sensor collects the signal of the falling medication and transmits it to the counter, obtains the quantity information of the falling medication, and then transmits it to the quantity comparator.

[0018] The quantity comparator compares the quantity of the collected medication with the quantity threshold in the quantity threshold memory. If the quantity of the collected medication is equal to the quantity threshold, the quantity comparator outputs a control signal to the control end of the electric valve to control the electric valve to close, and no more medication is dispensed into the compartment.

[0019] When all the required medications fall into the receiving tray along the corresponding medicine delivery tubes, the weighing device measures the overall weight information of the receiving tray and the medications on it, and inputs it to the first pressure comparator. The first pressure comparator compares the collected weight numerical information with the first pressure threshold in the first pressure threshold comparator. When the collected weight numerical value is equal to the first pressure threshold, it indicates that the medications are dispensed correctly. At this time, the first pressure comparator outputs a control signal to the control end of the medication reminder device, activates the medication reminder device, emits a medication reminder signal to remind the patient to take the medication, and indicates the location of the medications.

[0020] Furthermore, it also includes a first timer and a first timing comparator;

[0021] The first timer is connected to the output end of the first pressure comparator, the output end of the first timer is connected to the first input end of the first timing comparator, the second input end of the first timing comparator is connected to a first timing threshold memory, and the output end of the first timing comparator is connected to the remote terminal.

[0022] When the first pressure comparator outputs a control signal to remind the patient to pick up the medications, the first timer starts timing and transmits the timing information to the first timing comparator. The first timing comparator compares the collected timing time data with the first timing threshold in the first timing threshold memory. When the collected timing time data is greater than or equal to the first timing threshold, it indicates that the patient has exceeded the time limit and has not picked up the medications. At this time, the first timing comparator outputs information to the remote terminal for the patient's family members or medical staff to view, so as to confirm the patient's situation and facilitate manual reminder.

[0023] Furthermore, the meal reminder mechanism includes a camera and a meal reminder device;

[0024] The camera is installed in the dining room and the kitchen, the output end of the camera is connected to the remote terminal, and the meal reminder device is installed in the kitchen and the dining room.

[0025] The camera captures the video images of the kitchen and the dining room and transmits them to the remote terminal for it to confirm whether the patient has eaten. The meal reminder device is installed in the kitchen and the dining room to remind the patient to eat and facilitate the patient to determine the eating location.

[0026] Furthermore, the sleeping reminder mechanism includes a sleeping reminder device, a pressure sensor, a second pressure comparator, and a switch;

[0027] The sleeping reminder device is set in the bedroom. The activation end of the pressure sensor is connected to the output end of the sleeping reminder device. The pressure sensor is installed on the bed body and is used to collect the pressure signal of the patient lying on the bed body. The output end of the pressure sensor is connected to the first input end of the second pressure comparator. The second input end of the second pressure comparator is connected with a second pressure threshold memory;

[0028] The switch is connected in series between the bedroom lighting and the power supply. The output end of the second pressure comparator is connected to the control end of the switch.

[0029] When the sleeping reminder time arrives, the timer sends a control signal to the sleeping reminder device, and the sleeping reminder device starts to send a sleeping reminder signal to remind the patient to enter the bedroom to rest.

[0030] The pressure sensor detects the pressure signal of the patient lying on the bed body and transmits it to the second pressure comparator. The second pressure comparator compares the value of the collected pressure signal with the second pressure threshold in the second pressure threshold memory. When the value of the collected pressure signal is greater than or equal to the second pressure threshold, it indicates that the patient has already lain on the bed. At this time, the output end of the second pressure comparator outputs a control signal to the control end of the switch to disconnect the switch and automatically turn off the lighting in the bedroom.

[0031] Furthermore, the going-out reminder mechanism includes a going-out reminder device. The going-out reminder device is installed on the door lock, and the output end of the going-out reminder device is connected to the remote terminal.

[0032] The going-out reminder device is set at the door lock to remind the patient to remember to lock the door when going out. At the same time, the output end of the going-out reminder device is connected to the remote terminal so that the patient's family members or medical staff can obtain the information that the patient has gone out.

[0033] Furthermore, the display module includes a display and LED lights. The display is set on the indoor wall, and the LED lights are respectively installed on the medication reminder mechanism, the meal reminder mechanism, the sleeping reminder mechanism, and the going-out reminder mechanism.

[0034] The display module uses the display to display videos and at the same time uses the LED lights to display light signals for the convenience of the patient to view.

[0046] During use, timing is carried out through the clock and the timer on the wearable component, and control signals are sent to each reminder mechanism at the preset reminder times to control the start of each reminder mechanism and send out reminder signals.

[0047] When the preset reminder time arrives, the timer also sends a control signal to the display module to control the display module to display the preset video corresponding to the operation of the corresponding reminder mechanism. The patient can watch the video to understand the operations required of himself. The information acquisition is more intuitive, more conducive to the patient's understanding, and the guiding effect on the patient is better.

[0048] In a preferred solution of the present invention, as Figure 2 shown, the medication reminder mechanism includes a medicine placement box 1, a medicine delivery tube 2, a photoelectric sensor 3 (such as FT series, BEN500-DDT, etc.), a receiving tray 4, a counter 5 (such as 74X161, 74X191, etc.), a first pressure comparator 6, and a medication reminder device 7. The comparator in this embodiment can adopt a digital comparator or an analog comparator, such as LM324, LM339, etc. The front end of the comparator can be electrically connected to a digital-to-analog conversion module as needed, such as AK4021, etc.

[0049] The top of the medicine placement box 1 is open, and a box cover 10 for sealing the opening is provided at the opening, and the box cover 10 is snap-connected to the opening. A hook or snap mechanism is provided on the medicine placement box 1, and the medicine placement box 1 can be hung or snap-connected to a certain place indoors.

[0050] The medicine delivery tubes 2 correspond to the compartments 9 one by one. The top of the medicine delivery tubes 2 is communicated with the bottom of the corresponding compartments 9. The photoelectric sensor 3 is arranged on the inner wall of one end of the medicine delivery tube 2 close to the compartment 9. The output end of the photoelectric sensor 3 is electrically connected to the counter 5. The counter 5 is electrically connected to the first input end of the quantity comparator through the analog-to-digital conversion module. The second input end of the quantity comparator is electrically connected with a quantity threshold memory (such as 24CXX series, 93CXX series, etc.). The output end of the quantity comparator is electrically connected to the control end of the electric valve.

[0051] The receiving tray 4 is arranged at the bottom of the medicine delivery tube 2. The bottom of the receiving tray 4 is connected with a weighing device 8 (such as an existing weighing scale, etc.). The output end of the weighing device 8 is electrically connected to the first input end of the first pressure comparator 6. The second input end of the first pressure comparator 6 is electrically connected with a first pressure threshold comparator.

[0052] The medicine reminder device 7 is installed on the medicine placement box 1.

[0053] When the clock reaches the medicine reminder time, the timer sends a control signal to the medicine reminder mechanism, and the medicine reminder mechanism starts. The electric valve opens, and the medicine in the compartment 9 of the medicine placement box 1 falls from the bottom of the compartment 9 into the medicine delivery tube 2. At this time, the photoelectric sensor 3 collects the signal of the falling medicine and transmits it to the counter 5, obtains the quantity information of the falling medicine and then transmits it to the quantity comparator.

[0054] The quantity comparator compares the size of the collected medicine quantity with the quantity threshold in the quantity threshold memory. If the collected medicine quantity is equal to the quantity threshold, the quantity comparator outputs a control signal to the control end of the electric valve to control the electric valve to close, and no more medicine is delivered in the compartment 9.

[0055] When all the required drugs fall into the receiving tray 4 along the corresponding drug delivery tube 2, the weighing device 8 measures the overall weight information of the receiving tray 4 and the drugs thereon, and inputs it into the first pressure comparator 6. The first pressure comparator 6 compares the collected weight numerical information with the first pressure threshold in the first pressure threshold comparator. When the collected weight numerical value is equal to the first pressure threshold, it indicates that the drug delivery is correct. At this time, the first pressure comparator 6 outputs a control signal to the control end of the medication reminder 7 to activate the medication reminder 7, emit a medication reminder signal, remind the patient to take the medicine, and prompt the location of the medicine.

[0056] In a preferred embodiment of the present invention, for Alzheimer's patients, it further includes a first timer and a first timing comparator. The first timer is electrically connected to the output end of the first pressure comparator, the output end of the first timer is electrically connected to the first input end of the first timing comparator, the second input end of the first timing comparator is electrically connected to a first timing threshold memory, and the output end of the first timing comparator is electrically connected to the remote terminal.

Each device is electrically connected to the remote terminal through the wireless communication module.

[0057] When the first pressure comparator outputs a control signal to remind the patient to pick up the medicine, the first timer starts timing and transmits the timing information to the first timing comparator. The first timing comparator compares the collected timing time data with the first timing threshold in the first timing threshold memory. When the collected timing time data is greater than or equal to the first timing threshold, it indicates that the patient has exceeded the time limit and has not picked up the medicine. At this time, the first timing comparator outputs information to the remote terminal for the patient's family members or medical staff to view, so as to confirm the patient's situation and facilitate manual reminder.

Each threshold memory in the present utility model can be electrically connected to a human-computer interaction module (such as intelligent devices like computers and touch screens) so as to manually input thresholds and the threshold parameters can be replaced as needed.

[0063] When the sleep reminder time arrives, the timer sends a control signal to the sleep reminder. The sleep reminder is activated and emits a sleep reminder signal to remind the patient to enter the bedroom to rest.

[0064] The pressure sensor detects the pressure signal of the patient lying on the bed body and transmits it to the second pressure comparator. The second pressure comparator compares the magnitude of the collected pressure signal value with the second pressure threshold in the second pressure threshold memory. When the collected pressure signal value is greater than or equal to the second pressure threshold, it indicates that the patient has already lain on the bed. At this time, the output end of the second pressure comparator outputs a control signal to the control end of the switch to turn off the switch and automatically turn off the bedroom lighting.
