Description

Technical Field

[0001] The invention relates to the technical field of medication reminders, and more particularly to a medication reminder device that is convenient for elderly people to carry when going out. Background Art

[0002] As the elderly's lifestyle and pace of life change, they are increasingly taking outdoor activities such as exercising and traveling. The elderly are often accompanied by chronic diseases such as cardiovascular and cerebrovascular diseases (hypertension, coronary heart disease, stroke, etc.), diabetes, digestive system diseases, etc., which require long-term medication; at the same time, there are also some diseases that require temporary medication treatment or control according to physical conditions, such as eczema, dermatitis, urinary tract infection, hyperacidity, angina pectoris, etc.; and, as the elderly's health awareness continues to improve, the use of health care drugs is also gradually increasing.

[0003] However, the elderly often forget to bring their medicines when they go out, and they are prone to forgetting the time to take their medicines when they are out. In addition, their children are unable to grasp the situation and remind them in time, resulting in the elderly being unable to take their medicines on time, which worsens their condition.

[0004] Therefore, how to remind the elderly to take medicine on time is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a medicine reminder device which is convenient for the elderly to carry when going out for activities, so as to timely remind the elderly to take medicine on time.

[0060] The external setting module sets daily medication plan, temporary medication plan and travel plan according to the external device information;

[0061] Specifically, the daily medication plan is a medication plan for chronic diseases that require long-term medication, and the temporary medication plan is a plan for temporary reuse of medications based on the physical condition of the elderly. The medication plan generally includes information such as the time of medication, dosage, whether to take the medication after meals, etc., and specific prompt information can be displayed on the touch screen. The travel plan includes the travel time and the type and amount of medication to be carried. The type and amount of medication prompt information are displayed on the touch screen to remind the elderly to carry the correct type and amount of medication before traveling. In order to facilitate the setting of the medication plan, a voice module and an external setting module are also set up to set the plan based on the voice recognition information and the information input by the connected external device.

[0062] The reminder and confirmation module sends out a reminder message for carrying medicines before departure according to the travel plan and time; sends out a reminder message for taking medicines at the planned medication time according to the daily medication plan, temporary medication plan and time; if no medication confirmation message is received after the time length is set at the planned medication time, a guardian reminder message is sent to the external device through the communication unit.
