International Classification:

G09B 23/28

US Classification:

434262000

Abstract:

An anatomical model for simulating internal body structures of a patient, which in one embodiment includes a shell that simulates a body cavity and a length of animal tissue that simulates an organ in the body cavity. A sheath surrounds the animal tissue and is secured at one or more anchor points in the shell to support the animal tissue in the shell. In one embodiment, one or more force sensors are positioned to detect forces on the animal tissue or the shell.

International Classification:

A61M 5/168
A61M 5/142

US Classification:

604 66, 604151

Abstract:

Provided is an extended use self-contained, wearable medical device. The device is preferably configured with an infusion deployment mechanism for variably inserting and retracting an infusion needle to different depths, or completely retracting the infusion needle from the infusion site and then re-inserting the infusion needle after a predetermined period of time, throughout an infusion cycle for extending the viability of the infusion site. Another embodiment comprises dual needle deployment mechanisms which may also variably insert and retract the infusion needles. A flow sensor is preferably provided for detecting the stoppage of flow through the infusion cannula and signaling the needle deployment mechanism to attempt infusion at a different depth or to deploy a second infusion needle. A re-fillable reservoir assembly is preferably provided for supplying a drug over the extended use of the device. Another embodiment comprises a partially reusable and partially disposable medical device implementing the above features.

B65D 81/00

US Classification:

206515, 22056001

Abstract:

A shipping container integrates a sharps disposal container with a new product storage container for shipping. The storage container stores new product. A sharps disposal container receives used sharps. One of the storage container and the sharps disposal container is disposed within the other of the storage container and the sharps disposal container for shipping. A lid is adapted to be connected to the outermost container of the sharps disposal container and the storage container for shipping and to a top of the sharps disposal container for receiving used sharps.

US Classification:

604506, 604207, 604198, 604173, 604140

Abstract:

A drug delivery device () for administering a low dose of a medicament includes a housing () and a drug reservoir () disposed in the housing (). A needle () is connected to the drug reservoir (). A pressure applying member () is movably connected to the housing () and is movable between first and second positions. The pressure applying member () does not apply pressure to the drug reservoir () in the first position and applies pressure to the drug reservoir () in the second position to dispense medicament stored in the drug reservoir (). A method of administering a low dose of insulin to simulate a first-phase insulin response of a pancreas is also disclosed.

International Classification:

A61M 5/142

US Classification:

604506, 604151, 604 67

Abstract:

An infusion pump system is disclosed for dispensing liquid medication, such as insulin. The infusion pump system includes a first reservoir for storing liquid medication, a first fluid driver for exerting pressure on the first reservoir, a second reservoir for storing liquid medication, and a second fluid driver for exerting pressure on the second reservoir. One or more valves are used to permit flow of liquid medication from the first reservoir to the second reservoir, and to permit flow of liquid medication from the second reservoir to an infusion site. Each of the valves is selectively opened or closed to fill the second reservoir with liquid medication from the first reservoir and to dispense liquid medication from the second reservoir to the infusion site. A controller and one or more sensors are used to monitor and control the system.
