Patent application serial number 814491 has not been assigned to a company or institution.
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present disclosure is generally directed to reservoirs, particularly reservoirs containing a medicament. More particularly, the present disclosure is generally directed to determining information related to a drug reservoir, which may help to ensure that a delivery device can only be used with a drug reservoir for which it is intended. As just one example, such medicament reservoirs may comprise an ampoule, a cartridge, a vial, or a pouch, and may be used with a medical delivery device. Exemplary medical delivery devices include, but are not limited to syringes, pen type injection syringes, credit-card-shaped injection devices, pumps, inhalers, or other similar injection or infusing devices that require at least one reservoir containing at least one medicament.
"Medicament reservoirs such as ampoules, cartridges, or vials are generally known. Such reservoirs are especially used for medicaments that may be self administered by a patient. For example, with respect to insulin, a patient suffering from diabetes may require a certain amount of insulin to either be injected via a pen type injection syringe or infused via a pump. With respect to certain known reusable pen type drug delivery devices, a patient may load a cartridge containing the insulin into a proximal end of a cartridge holder. After the cartridge has been correctly loaded, the user may then be called upon to select a dose of medicament. Multiple doses may be dosed from the cartridge. Where the drug delivery device comprises a reusable device, once the cartridge is empty, the cartridge holder may be disconnected from the drug delivery device and the empty cartridge may be removed and replaced with a new cartridge. Most suppliers of such cartridges recommend that the user may dispose of the empty cartridges properly. Where the drug delivery device comprises a disposable device, once the cartridge is empty, the user may be recommended to dispose of the entire device.
"Such known self administration systems requiring the removal and reloading of empty cartridges have certain limitations. For example, in certain generally known systems, a user may simply load a new cartridge into the delivery system without the drug delivery device or without the cartridge having any mechanism of preventing cross use of an incorrect cartridge. That is, the drug delivery device does not have a mechanism for determining whether the medicament contained in the cartridge is indeed the correct type of medicament to be administered by the patient. Alternatively, certain known drug delivery devices do not present a mechanism for determining whether the correct type of medicament within the cartridge should be used with that particular drug delivery system. This potential problem could be exacerbated given that certain elderly patients, such as those suffering from diabetes, may have limited manual dexterity. Identifying an incorrect medicament is quite important, since the administration of a potentially incorrect dose of a medicament such as a short-acting insulin in lieu of a long-insulin could result in injury or even death.
