APPARATUS AND METHODS FOR ADMINISTERING A PHARMACEUTICAL AGENT
First Claim
1. An injection device adapted to be worn on the body of a patient, the device comprising:
- an injector comprising a reservoir containing an agent for treating hypoglycemia and a needle comprising a first end portion connected to the reservoir and a second end portion adapted to be inserted into the body of the patient;
an acoustical alarm; and
a control assembly comprising a signal receiver configured to receive signals from a glucose sensor, the control assembly being electrically coupled to the acoustical alarm and configured to activate the acoustical alarm upon a signal received in the signal receiver being indicative of hypoglycaemia, the control assembly being configured to automatically cause the injector to administer through the needle a dose of the agent in the reservoir to the patient after a predetermined period of time from the signal receiver receiving the signal indicative of hypoglycaemia, the control assembly having a manually activated switch that when activated prior to the expiration of the predetermined period of time causes the control assembly to abort the automatic injection of the agent.

Abstract
An injection device adapted to be worn on the body of a patient. The device includes an injector containing an agent for treating hypoglycaemia. A control assembly including a signal receiver is configured to receive signals from a glucose sensor, the control assembly being electrically coupled to an alarm and configured to activate the alarm upon a signal received in the signal receiver being indicative of hypoglycaemia, the control assembly being configured to cause the injector to administer through a needle a dose of the agent to the patient after a predetermined period of time of the signal receiver receiving the signal indicative of hypoglycaemia, the control assembly having a manually activated switch that when activated prior to the expiration of the predetermined period of time causes the control assembly to abort the injection of the agent.

15. An injection device adapted to be worn on the body of a patient, the device comprising:
-
a housing having a sterile inner chamber, the housing having a bottom wall with a through opening that extends between an inner surface and an outer surface, a portion of the outer surface that possesses the through opening being configured to be worn in contact with the body of the patient, and a septum positioned in and/or over the through hole opening that assists in maintaining the sterile integrity of the sterile chamber; and an injector located within the sterile inner chamber, the injector comprising a reservoir containing an agent for treating hypoglycaemia, and a needle comprising a first end portion connected to the reservoir and a second end portion adapted to be inserted into the body of the patient, the second end portion of the needle being movable between a first position wherein the second end portion of the needle partially resides in the septum and a second position where the second end portion of the needle extends through the septum and at least partially resides external to the bottom wall, the septum and second end portion of the needle constructed so that the second end portion of the needle is capable of piercing through the septum when the second end portion of the needle is moved between the first position and the second position.

16. An injection device adapted to be worn on the body of a patient while the patient is unable to self-administer a first pharmaceutical agent, the device comprising:
-
an injector comprising a reservoir containing a first pharmaceutical agent, and a needle comprising a first end portion connected to the reservoir and a second end portion adapted to be inserted into the body of the patient; an acoustical alarm; and a control assembly comprising a signal receiver configured to receive signals from a sensor that is capable of monitoring a relevant biomarker in the patient, the control assembly electrically coupled to the acoustical alarm and configured to activate the acoustical alarm upon a signal received in the signal receiver being indicative of a presence of the biomarker, the control assembly configured to automatically cause the injector to administer through the needle a dose of the first pharmaceutical agent in the reservoir to the patient after a predetermined period of time of the signal receiver receiving the signal indicative of the presence of the biomarker, the control assembly having a manually activated switch that when activated prior to the expiration of the predetermined period of time causes the control assembly to abort the automatic injection of the agent. - View Dependent Claims (17, 18, 19, 20)
