The present invention relates to an at least partly implantable system for injecting a substance into a patient's body. The system comprises at least one implantable infusion needle arranged in at least one first housing, the at least one implantable infusion needle having a tip end for injecting a substance into a penetration area of a patient, and at least one drive unit coupled to the at least one implantable infusion needle and arranged for moving the tip end of the at least one infusion needle for varying the penetration site, wherein the at least one drive unit is a drive unit arranged for moving the tip end of the at least one infusion needle using hydraulic force. The system is adapted to use infusion liquid to be injected into the patient's body as hydraulic fluid.

With the pharmaceutical injection system in an embodiment, pharmaceutical injection amount setting conditions for setting a pharmaceutical injection amount are inputted to a portable terminal (300), and the pharmaceutical injection amount setting conditions are transmitted to a health care worker-use information terminal (500). The portable terminal (300) receives the pharmaceutical injection amount set on the basis of the pharmaceutical injection amount setting conditions transmitted from the health care worker-use information terminal (500), and transmits the pharmaceutical injection amount to a pharmaceutical injection device (100). The health care worker-use information terminal (500) receives the pharmaceutical injection amount setting conditions transmitted from the portable terminal (300), and the pharmaceutical injection amount set on the basis of the pharmaceutical injection amount setting conditions is inputted. The health care worker-use information terminal (500) transmits the inputted pharmaceutical injection amount to the portable terminal (300). The pharmaceutical injection device (100) receives the pharmaceutical injection amount transmitted from the portable terminal (300), and a piston drive mechanism (101) is driven on the basis of the pharmaceutical injection amount.

A distributed system can include a server outside of a clinical environment and a connectivity adapter and a plurality of infusion pumps within the clinical environment. The connectivity adapter can receive from the server a location of an update, such as a drug library update or an operational software update, to be delivered to the infusion pumps. The location can be received over a first messaging communication channel of a network, and the update data can be received over a second, data communication channel of the network. The update data can be stored at the connectivity adapter such that it can be sent to the infusion pumps.

The invention is a process and system, consisting of a reinjection pump, connecting tubing, a reinjection cannula and a recipient site, with fluid management features including a peristaltic pump head and controls for pressure limits, flow rates and flow distribution wherein the process of controlling the reinjected fat and fluid is unique because of the control of flow rates, pressures, matching cannula hole sizes, and maintaining a closed continuous system where the harvesting and reinjection is done all together with a completely closed system. The process utilizes a method and control system to manage pressure levels during reinjection procedures of viable soft tissue. Although this case specifically relates to its use in the reinjection of adipose fat and other tissue back into the body during liposuction procedures, it can be applied to any medical procedure of introducing or re-introducing materials into the body.

A closed-loop control for a medical therapeutic system is disclosed that includes one or more processes or components for/in the medical therapeutic system, a controller configured to determine whether one or more operations of the process(es) or component(s) are within a corresponding safety envelope, and one or more sensors. The process(es)/component(s) are configured to deliver a controlled amount of a substance, energy or force to a patient. The sensor(s) are configured to measure or determine a value of a measurable parameter of the process(es)/component(s) and/or effected by the operation(s), and provide the value(s) of the measurable parameter(s) to the controller. The controller determines whether each of the operation(s) are within the corresponding safety envelope according to a corresponding function that mathematically describes the operation. The safety envelope corresponds to known safe values of the measurable parameter, or an unmeasured parameter based on the measurable parameter.

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a user involves storing alert configuration information for the user, identifying an alert condition while operating the infusion device to deliver the fluid based at least in part on the alert configuration information for the user, and in response to identifying the alert condition, providing a user notification in accordance with the user's stored alert configuration information.

A portable monitoring device operates to remotely monitor a medical device for use in hospitals and the like. The portable monitoring device includes a signal receiver for receiving a first wireless signal. The medical device can be a portable drip infusion set of the type having a liquid supply, a drip chamber downstream of the liquid supply for forming liquid drops, a flexible tube connecting the drip chamber with an injection needle and a signal emitter for emitting the first wireless signal. The infusion set and the monitoring device each can include printed circuit boards (PCBs) and mutually interconnectible electric contacts. The infusion set includes an electronic circuitry that blocks programming of the infusion set when the monitoring device is not electrically connected to the infusion set.

A flow meter includes an image sensor and a processor. The image sensor is configured to capture an image of a drip chamber. The processor is configured to determine whether the captured image of the drip chamber contains a match to a template, and to apply a blurring function to the image captured by the image sensor of the drip chamber such that the processor can determine if the captured image contains a match to the template.

An apparatus for indicating a change in operation of a medical infusion pump. The apparatus includes a memory configured to store an original pump parameter and a current pump parameter. The apparatus further includes a programmable circuit in electrical communication with the memory, the programmable circuit programmed to display the original pump parameter and the current pump parameter. A method indicates a change in operation of a medical infusion pump.

A body-worn medication delivery pump having a patch form factor is provided that includes an integrated plethysmographic module that employs a photoplethysmographic multi-chip package disposed in a frame designed to maintain contact with a wearer's skin during motion, and reduces cross-talk and ingress of stray light, a controller of the pump programmed to adjust its medication delivery algorithms responsive to outputs of the plethysmographic module.
