Description

NOVEL MEDICATION DISPSENSER
FIELD OF THE INVENTION
The invention is directed to a device to help patients handle and keep track of multiple medications, more specifically, to a pharmaceutical formulation dispenser.
BACKGROUND OF THE INVENTION
The most common problems encountered in the health care system is patient compliance. Patients might do the following: continue to take medications that has been stopped by the doctor; continue to take medications that has expired but they still have it in their stock; take the wrong strength of the medication;
take the medication at the wrong time; mixing up their medications leading to drug-drug interactions; taking their medications with or without food leading to drug-food interaction;
taking another patient's medication by error if they live in the same facility; forgetting to take their medications all together.
Patient's non-compliance is usually due to: ageing (as people grow older they tend to be more forgetful; disability (whether cognitive or physical); poor communication with appropriate health care provider; and carelessness.
The consequences of non-compliance can be detrimental to both patient and the economy.
Researchers have shown that the impact of non-compliance on patient outcomes.
Each year drug non-compliance is the cause of: 10% of all hospital admissions; 25% of hospital admissions for the elderly; 23%
of all nursing home admissions; and adverse drug reactions are a leading cause of patient mortality.
Not only will closing the medication adherence gap be expected to improve the quality of healthcare, and promote enhanced patient outcomes but it is also expected to encourage better chronic care management as well as also significantly reducing the overall cost to Canadian healthcare system.
Moreover, some financial impact on the healthcare system from medication non-adherence is estimated to annually cost of the Canadian healthcare system between $7 billion and $9 billion. These costs include additional physician visits, extra laboratory tests, additional drug therapy, hospital ER visits, hospital admissions and short-term disability insurance payments.
Current approaches to improve compliance: current weekly organizers have the same layout in terms of days of the week and number of doses per day. They are known as blister packs and commonly called bubble packs. However, these blister packs are filled in by hand. The tablets are placed in the palm of the hand and filled one by one into the designated slots increasing the chances of contamination. The blister packs are available as one-piece equivalent to a one-week supply.
There are increased chances of error as the pills could be misplaced during the filling process. If a patient's medication regimen is altered, the entire blister pack has to be deblistered and refilled right from the beginning. During the process of filling the pills may be scattered or dropped on the floor thus increasing the waste to the pharmacy and polluting the environment. It is labour consuming as a technician or a pharmacist has to fill the medications one by one into each slot. Interruptions during the filling process increases the chance of errors placing and labelling the medications. Blister packs for a whole treatment such as weekly or monthly treatment tend to be large and require the somewhat tricky task of popping the blister to retrieve multiple tablets, capsules or the like. If one desires is out of the house when it is time for the dosage, one must either skip the dose, delay the dose or carry loose tablets until the dosage time.
In light of the above, there is still an unmet need to provide a more convenient way for a patient to self-administer medications provided to him/her while taking into account all of the possible convenience issues or changes in dosage which may occur during a treatment regimen.
