A portable medical apparatus for administering a fluid drug in doses, including a first housing including a reservoir unit with an outlet into a fluid path for conducting the drug, a second housing including a conveying unit for dispensing the drug from the reservoir unit in doses and a suitable controller for controlling the conveying unit, an adaptor including a coupling structure for receiving the first housing and the second housing and an attaching structure for extra-corporeally carrying the adaptor on a patient, wherein the conveying unit and the reservoir unit can be joined together to form an integrated mechanical and fluidic unit, and coupled to and decoupled from at least two differently configured adaptors, wherein at least one of the adaptors is configured to be directly attached to the surface of the skin and at least one of the adaptors is configured to be worn on or carried by an article of clothing or a wearing system (e.g., a belt).

An infusion pump system is disclosed. The infusion pump system includes an infusion pump and a controller device in wireless communication with the infusion pump, wherein the controller including instructions for controlling the infusion pump, wherein the instructions may be synchronized with a secure web portal.

A wearable drug delivery device for monitoring unintended over-delivery and/or under-delivery of a stored liquid drug are provided. An absolute pressure sensor can be positioned within the fluid path of the drug delivery device. The absolute pressor sensor can detect both ambient pressure (e.g., absolute or atmospheric pressure) and relative pressure (gage or pumping pressure). Based on the detected pressures, the effects of external ambient pressure on air with the fluid path can be determined during both intended drug delivery events and unintended drug delivery events. In turn, under-delivery and/or over-delivery of the liquid drug can be determined. Based on the severity of the determined under-delivery or over-delivery of the liquid drug, alarms indicating different urgencies can be provided to the user.

The present invention discloses a pump for measuring a pressure of fluid to be transferred, a fluid transport system using the same, and a method for operating the system. The pump includes a pumping portion alternately generating a positive pressure and a negative pressure; a first diaphragm which is provided on one side of the pumping portion and of which a shape is changed as the positive pressure and the negative pressure are alternately generated; a transport chamber which sucks and discharges a transport target fluid corresponding to the deformation of the first diaphragm; a second diaphragm which is provided on the other side of the pumping portion; a monitoring chamber which is provided on one side of the second diaphragm and of which a pressure changes corresponding to the deformation of the second diaphragm; and a pressure measuring portion measuring a pressure change of the monitoring chamber.

A medical liquid injection device may include a pump module, a pivot fitting, at least one sensor, and a processor. The pump module may include a shaft configured to perform a linear reciprocating movement along one direction. The pivot fitting may include a first end connected to the shaft and a second end configured to perform a rotational reciprocating movement by the linear reciprocating movement. The at least one sensor may obtain contact time information on a time at which at least one sensor comes into contact with the second end. The processor may calculate a driving time of the pump module using the contact time information and determine occurrence of occlusion of the medical liquid injection device on the basis of the driving time.

A jacket for watertight sealing a medical device is disclosed. The jacket includes a flexible envelope having a first side and an opposing second side. The first side has a first sealing lip configured to surround the medical device and a second sealing lip spaced from the first sealing lip and configured to surround the medical device. The flexible envelope has an envelope contacting sealing end that is fixedly connectable to the opposing second side. A method of using the inventive jacket includes mounting a medical device on a skin site of an extremity of a user and placing the jacket onto the skin site such that the first sealing lip and the second sealing lip surround the medical device. The flexible envelope is then wrapped around the extremity and fixedly connects the envelope contacting sealing end to the opposing second side of the flexible envelope.

An adhesive patch for a drug delivery device with a bacteria impermeable sterility margin surrounding an edge surface of the adhesive patch is disclosed, as well as a drug delivery device fixed to such an adhesive patch and a method of assembling a drug delivery device with such an adhesive patch. In some arrangements, the sterility margin is attached to or integral with a lower liner on a lower surface of the adhesive patch. In other arrangements, the sterility margin is attached to or integral with an upper liner on an upper surface of the adhesive patch.

An infusion system includes an infusion pump configured to convey a fluid to be administered through a fluid conduit, a number of sensors for producing associated sensor data, and an AI unit configured to calculate a number of target variables depending on the number of sensor data using a statistical model as a basis, the statistical model having been trained using training data.

A medicament delivery device comprising a housing connected to a base and enclosing an interior, the interior having a fluid channel wherein the fluid channel passes from a first position in the interior, to a second position outside the interior, and to a third position in the interior.
