MEDICATION REMINDER SYSTEM
DESCRIPTION
TECHNICAL FIELD OF THE INVENTION
The present invention is designed for both the fields of pharmacy and medicine and is based on an alarm and reminder system The device reminds the patient at the correct time during the day to take the correct medicine The device is portable and is totally independent. The device is useful for patients with busy lifestyles, limited education or age related problems in complying with their medication regimen
INTENTIONS OF THE INVENTION
Most pharmacists who work in pharmacies provide some basic information about medication for patients. However, most of patients forget their medication or because of poor education, age and taking medicines at the incorrect time such as with cocktails or at the same time as other medicines. This can result in serious pharmacological and/or toxicological problems for the patient Furthermore, it may result in ineffective treatment of a disease and/or be harmful for the patient When a doctor prescribes medicine for a disease many factors are important such as the patient's condition, age, sex, weight and health background. The doctor also considers the pharmaco-kinetics of medicines in order to prescribe what best suits the patient When a patient does not take drugs in the way they are prescribed, the concentration of the medicine in the blood starts to be change resulting in ineffective treatment of the disease This harms the patient by wasting time, health and money
From another point of view, one of the biggest mistakes occurs among patients who take a medication too frequently which may have deleterious , toxicological effects Frequently, patients who may need to take several different medications may get confused and take them at the same time or with cocktails Ultimately, this may result in a harmful drug-drug interaction
Considering all about subjects, the physician and the pharmacist need to know if the patient follows the medication programme to learn about efficiency of the medication
By the way, the effect of biorhythm on medications is quite important Some body hormones act in ' time-cycle' such as ACTH and Cortisol. A programmed medication will improve the body-medication relation
A reasonable solution for all these complications is probably a portable patient- programmable medication reminder system Meanwhile, the physician will be able to consider medication programme and plan a new medication, if necessary A practical patient-programmable medication reminder system, preferably, addresses the needs of patients in a simple way Also most of patients are unable to recognize medication names or are unfamiliar with pharmaceutical language Limited education, senescence or the inability to follow written instructions are other factors resulting in the above problems A sufficient and successful patient-programmable medication reminder system needs to be designed in consideration of all above mentioned subjects Medication reminder systems:
Recent developments in both the pharmaceutical and electronics fields have resulted in improved medication reminders systems in earlv 90's The field is quite new and there are not too many varieties Today, the most widely used models are pager services and pill-boxes with alarms Pager services:
The prescription information is sent to the operation centre The information is loaded onto computers and is forwarded to the patient's pager to remind him/her of the correct times and doses of medications all day long
But the system is delayed if the signal doesn't access the patient's pager Problems in central operation units can harm medication programmes Pill-boxes with alarms: This system is based on a alarm clock mechanism The alarm alerts the patient at every medication time The patient opens the pill box and takes the medication
This system was designed for two sorts of medicine and is available for using tablets or pills The device doesn't address the needs of all pharmaceutical forms of medicines and is limited to two sorts of medicine DESCRIPTIVE DRAWING Fig. 1 is the front views of the module.
