Definitions
- the invention generally relates to the rupturing of pharmaceutical product packages and the recovery of the product from the package, and in particular to an apparatus for recovering pharmaceutical product from blister packs.
- a medical programme is facilitated by a medical pack that typically comprises multiple compartments for one or more pharmaceuticals, such as tablets, pills or capsules, together with time and date information.
- the medical pack enables a patient to easily identify the right dose of medicine to be taken at particular times of the right day.
- Medical packs are commonly prepared automatically by a dispensing device that accurately makes up a prescription by filling each compartment in a medical pack with the correct amount of pharmaceutical tablets, pills or capsules that have been grouped in preparation for dispensing.
- Blister packs are sterile sealed packets for shipping pharmaceutical products and it is a legal requirement for any quantity of such pharmaceutical product to remain in loose unsealed form for not more than two weeks.
- Blister packs typically comprise a plastic former with a number of compartments in which pharmaceuticals reside and a foil layer that covers and seals each compartment.
- One method is to individually remove and separate (deblister) the pharmaceuticals from the blister pack by hand in order to fill the pills loosely into the dispensing device.
- a manual deblister device typically has deblister rings that are aligned between rows of pharmaceuticals in a blister pack and a roller or pressing component for pressing the pharmaceuticals from the blister compartments through the foil layer.
- Manual deblister devices are typically either operated by manual force to crank a handle or have a single speed motor to drive the machine or close the press.
- Manual deblister devices typically require a pharmacist or technician to change the setup configuration of the device for each blister pack to account for the share volume of the different shapes and sizes of the different types of pharmaceuticals available. Changing the configuration of the device can be an onerous process, typically requiring removing the roller or pressing component and adjusting the guides to align to each different blister pack. Each setup is time consuming and difficult for a pharmacist and many default to hand removing.
- a further disadvantage is that manual deblister machines can do a poor job at consistently extracting the pharmaceuticals if they are not correct set up, often causing the
