Problems solved by technology

Therefore, the dosage is not fully controlled and can cause serious harm to the patient
[0006] The second flaw is the padding and setting of the system
In the second case, cannula insertion is controlled remotely, but the inserter remains in the patch pump, which takes up space and makes patch pumps difficult to downsize

[0180] Figure 25a , Figure 25b , Figure 25c and Figure 25d A second embodiment of a dual function connector 41 is shown in which a rotating element moves a pin in a groove instead of a U shape. see especially Figure 25b , which shows the rotating element 57 moving the pin 55 in the groove 56 . The disposable housing 20 is then manually placed on the patient's skin after removal of the release layer of protective adhesive on the support. The movable needle support 47 is manually activated by pushing a release mechanism at the back side of the dual function support 41 . The dual-function support 41 is then released manually by pressing the preferably transverse latch.

Abstract

A fluid delivery device for delivering small quantities of a fluid such as insulin to a patient, comprising a disposable unit comprising a disposable housing (20) that comprises one lower part and one upper part, the lower and upper parts together forming a shell that defines an internal partial toroidal arcuate cavity. The disposable housing fits together with a drive unit (34).The disposable housing (20) contains an arcuate cylinder (28) for containing fluid to be delivered, a piston (38) movably mounted in the cylinder for driving out fluid to be delivered, an adhesive support (14) for attaching the disposable housing to a patient, and a cannula (22) that when the disposable housing is attached to a patient is insertable in the patient's skin for delivering fluid to the patient. The drive unit (30) is preferably removably mounted on a front face of the disposable housing (20) opposite the adhesive support, the removable drive unit having a shape that when fitted complements the shape of the front face of the disposable housing to form with the disposable housing. The drive unit (30) comprises means for actuating the piston and a control unit for the device.

Description

technical field [0001] The invention described herein is directed to an ultra-compact fluid delivery system that includes a fluid pumping device and an associated multifunctional remote control that includes automatic filling and cannula insertion features. The invention is also directed to methods for administering fluids to a patient. The fluid delivery system according to the invention is intended for use in any medical application. [0002] The system is particularly suitable for use as a subcutaneous or transdermal drug delivery patch adhesively attached to the skin of a patient. It is preferred for use as an insulin patch pump given that its structure makes it extremely small and very light, while being able to deliver very small amounts of insulin or other drugs. Background of the invention [0003] Insulin pumps are well known in the art as an alternative to multiple daily injections of insulin via insulin syringes or insulin pens. [0004] A wearable patch pump a...
