Description

Anti-lost device for patients with dementia

Technical Field

The invention belongs to the technical field of anti-loss devices, and in particular relates to an anti-loss device for patients with Alzheimer's disease.

Background technique

Alzheimer's disease can lead to a series of cognitive function losses, including memory loss, decreased thinking ability, inattention, language disorders, behavioral and emotional changes, etc. As the disease progresses, patients may become confused, lose their sense of direction, be unable to independently complete daily life activities, and may even lose the ability to take care of themselves. Since Alzheimer's patients are prone to losing their sense of direction and memory loss, they often get lost when they are outdoors without special care. Therefore, some family members will equip Alzheimer's patients with anti-loss devices. For example, patent CN113327403A proposes an anti-loss device that is easy for Alzheimer's patients to carry, which points out the importance of anti-loss devices for Alzheimer's patients.

When the anti-loss device is used, the following problems exist:

The existing types of anti-lost devices are bracelet type and hanging type. Some patients with dementia may have resistance to wearing anti-lost devices, or feel uncomfortable with the devices on their hands or around their necks, which may cause patients to frequently take off the anti-lost devices, affecting the effectiveness of the devices. Moreover, if patients take off the devices, they may forget to bring them back due to memory loss, causing the devices to be lost, which also causes inconvenience to their family members.

In addition, the anti-lost device relies on technical equipment and battery power. If the patient gets lost outdoors and the device loses its function because it has not been charged in time, family members cannot rely on the anti-lost device to quickly find the patient, which can easily put the patient at risk.

Therefore, we propose an anti-lost device for patients with Alzheimer's disease to solve the above problems.

The operating principle of the present invention is now described as follows: when the patient with Alzheimer's disease wears the first device body 1, the conical shell 71 is placed on the inner side of the outer garment, the first device body 1 is placed on the outer side of the outer garment, and then the limiting needle 11 on the surface of the first device penetrates the clothing, and the limiting needle 11 is inserted into the jack on the surface of the conical shell 71 and the conical seat 72. When the limiting needle 11 is inserted between the three limiting balls 10, the limiting needle 11 will squeeze and push the limiting balls 10 to the left, so that the three limiting balls 10 move to the left at the same time. The outer wall of the shell 71 is a conical surface. When the three limiting balls 10 move to the left together, the gaps between the three limiting balls 10 will expand, and the limiting needle 11 can be smoothly inserted between the three limiting balls 10. The limiting ball 10 can move in the spherical hole 9, and the limiting ball 10 cannot pass through the conical seat 72 through the spherical hole 9. When there is no limiting needle 11 between the three limiting balls 10, the three limiting balls 10 will resist each other and will not cause the limiting ball 10 to detach from the spherical hole 9. When the groove 12 on the surface of the limiting needle 11 is When the first device body 1 is located between the three limiting balls 10, a part of the three limiting balls 10 will be stuck in the groove 12 under the action of the extrusion force, so that the conical shell 71 and the limiting needle 11 can be fixed, so that the first device body 1 can be fixed on the outside of the patient's outer clothes. When the patient pulls the first device body 1 or other objects accidentally pull the first device body 1, the limiting needle 11 will pull the three limiting balls 10 to move to the right together. Under the extrusion of the conical surface of the conical shell 71, the three limiting balls 10 will move to the middle position of the inner side. , so that the limiting needle 11 can be squeezed more firmly, so as to prevent the first device body 1 from being separated from the patient's clothes. When the first device body 1 needs to be removed, the family can take the equipped strong magnet and place it on the left side of the conical shell 71. The strong magnet will attract the permanent magnetic ring 13 to move, and the permanent magnetic ring 13 drives the conical seat 72 and the limiting ball 10 to move to the left together. In the process of the three limiting balls 10 moving to the left, the gaps between the three limiting balls 10 will increase, so that the limiting needle 11 can be pulled out and the first device body 1 can be removed;

After the first device is worn, the top ring 16 will be squeezed to the right by the conical shell 71, and the top ring 16 drives the ring plate 15 to move to the right through the cross pin 142, so that the ring plate 15 and the two conductive blocks 17 are separated, thereby disconnecting the connection between the two conductive blocks 17. After the first device body 1 is installed, the first device body 1 can be powered on and operated by an external button. When the limit pin 11 is disconnected due to rust or other reasons, causing the first device body 1 to detach, the top ring 16 will be released from the limit, and the ring plate 15 will move to the left under the tension of the spring, so that the ring plate 15 and The upper and lower conductive blocks 17 are in contact, the lower conductive block 17 is electrically connected to the first micro power source 18, and the upper conductive block 17 is electrically connected to the buzzer 4 and the PLC controller. After the ring plate 15 is in contact with the upper and lower conductive blocks 17, the buzzer 4 will be powered on and make a sound to remind the patient that the first device body 1 has fallen, and the PLC controller will first control the micro air pump 21 to work, and at the same time transmit power to the second solenoid valve 26, so that the second solenoid valve 26 is powered on and opened, and the micro air pump 21 will transmit external gas to the lower tube 23 and the upper tube 22, and the gas is delivered to the protective airbag 191 through the short tube 24, so that the protective airbag 191 is inflated, and the protective airbag 191 drives the silicone plate 192 to move in the direction close to the circuit board 20, and squeezes the circuit board 20 in the upper and lower directions, thereby improving the impact resistance of the circuit board 20. When the micro air pump 21 and the second solenoid valve 26 are powered on for five seconds, the first device body 1 also falls to the ground. After five seconds, the PLC controller controls the micro air pump 21 to stop working, and delivers current to the first solenoid valve 25, so that the lower tube 23 is connected to the cooling chamber 53, and the gas inside the protective airbag 191 can be transported to the cooling chamber 53 along the lower tube 23 and the upper tube 22 for discharge, so as to avoid affecting the heat dissipation performance of the electronic components on the surface of the circuit board 20, and a temperature sensing element is provided on the surface of the circuit board 20. When the external temperature is too high, the temperature sensing element can control the micro air pump 21 and the first solenoid valve 25 to be energized through the PLC controller, so that the external airflow is transported to the cooling chamber 53 for discharge under the action of the micro air pump 21, and the airflow can be blown to the patient's body surface, thereby playing a certain cooling effect.

The shoes worn by the patients with Alzheimer's disease are specially customized. The side wall of the sole 5 is provided with a receiving groove 6. The micro-generator assembly 27 and the second device body 2 can be fixed in the receiving groove 6 by bolts. When the patient walks, the patient's foot will step on the insole 32, so that the massage airbag 36 and the buffer cavity 33 on the surface of the insole 32 are squeezed and the space is reduced, so that the gas inside the buffer cavity 33 and the massage airbag 36 is transported to the telescopic airbag 38 through the exhaust port 35 and the air inlet 31, so that the telescopic airbag 38 is inflated. The telescopic airbag 38 will expand, and the toothed plate 272 will move. The toothed plate 272 drives the shaft end of the micro-generator 271 to rotate counterclockwise through the meshing with the gear ring 28. When the patient's foot is lifted up, the buffer chamber 33 and the massage airbag 36 are made of elastic materials. When the foot is lifted up, the buffer chamber 33 and the massage airbag 36 will expand, thereby retracting the telescopic airbag 38. The massage airbag 36 will drive the toothed plate 272 to move rightward, and the micro-generator 271 is controlled by the meshing of the toothed plate 272 and the gear ring 28. 1 rotates clockwise, so that the micro-generator 271 generates current. The current generated by the micro-generator 271 will be transmitted to the second micro power source 39, which can charge the second micro power source 39. When the first device body 1 is lost and the patient has not found it, when the patient is far away from the first device body 1, the signal sent by the wireless signal transmitting end 42 inside the first device body 1 cannot be received by the wireless signal receiving end 41 inside the accommodating slot 6, and the wireless signal receiving end 41 will control the electromagnetic block 402 to be powered off through the PLC controller. After the electromagnetic block 402 is powered off, it will lose its magnetic force. The lifting plate 45 will drive the fixing pin 44 and the power-on plate 47 to move downward under the tension of the spring, so that the power-on plate 47 and the power-on block 48 are in contact, and the power-on plate 47 is electrically connected to the external power supply, and the power-on block 48 is electrically connected to the second device body 2, so that the circuit of the second device body 2 and the second micro power source 39 can be connected, so that the second device body 2 starts to work, and the family members can find the patient in time according to the signal sent by the second device body 2.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
