The present disclosure provides a new and innovative method and system for flow rate compensation in devices, such as infusion pumps. In various embodiments, a computer-implemented method includes determining a location of a plurality of infusion pumps in a pump stack including the plurality of infusion pumps and a fluid supply connected to each of the plurality of infusion pumps. The computer-implemented method also includes determining a reference infusion pump, in the plurality of infusion pumps, and adjusting the flow rate for each infusion pump in the plurality of infusion pumps based on the distance between the infusion pump and the reference infusion pump.

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.

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.

Various exemplary pumps with orientation independent liquid drug accessibility are provided. In general, a pump includes a reservoir configured to contain a liquid drug therein, a conduit configured to receive the drug therein from the reservoir, and a needle in fluid communication with the conduit and configured to deliver the drug therethrough to a patient wearing the pump. The conduit includes a mechanism configured to ensure that the conduit is in complete communication with the drug in the reservoir at least when the conduit is receiving the drug therein from the reservoir regardless of the patients orientation. In one exemplary embodiment, the mechanism includes a weight attached to the conduit. In another exemplary embodiment, the mechanism includes a fork at a free end of the conduit that is located in the reservoir.

The disclosed technology relates to medicinal fluid injection devices. In one aspect, a medicinal fluid injection device includes a housing having an opening in a side surface thereof, a storage container arranged inside the housing and configured to store a medicinal fluid, an injection needle connected to the storage container and configured to inject the medicinal fluid when stored in the storage container through the opening, and a cover body covering the opening, wherein the cover body includes a cover part configured such that the a shape of the cover part changes according to air pressure caused by the injection needle.

An injection device comprises an acoustic sensor configured to detect environmental acoustic signals; an acoustic signal generator operable to generate an acoustic signal; and a controller configured to control the acoustic signal generator to generate an alert having acoustic properties that are selected based on the detected environmental acoustic signals. A feedback system comprises: a first device comprising an acoustic signal generator operable to generate an acoustic signal; and a second device comprising an acoustic sensor configured to detect environmental acoustic signals, and a controller configured to control the acoustic signal generator of the first device to generate an alert having acoustic properties that are selected based on the detected environmental acoustic signals and one of the first device and the second device is an injection device, and the other one of the first device and the second device is a mobile device or a controller device.

Methods and devices for accurately pumping small quantities of liquid to a patient with a broad range of flow and low cost.

A medical device system. The system includes a first medical device, a first remote interface, and a second remote interface in communication with the first remote interface and the first medical device, wherein the first medical device sends a command to the first medical device through the second remote interface, and wherein when the second remote interface receives the command, the command must be confirmed by the second remote interface before the command is send by the second remote interface to the first medical device.
