A medical system includes an input assembly for receiving one or more user inputs. The input assembly includes at least one slider assembly for providing an input signal. Processing logic receives the input signal from the input assembly and provides a first output signal and a second output signal. A display assembly is configured to receive, at least in part, the first output signal from the processing logic and render information viewable by the user. The second output signal is provided to one or more medical system components. The information rendered on the display assembly may be manipulatable by the user and at least a portion of the information rendered may be magnified.

Implementations of the present disclosure are directed to a module for attachment to an injection device that includes a flexible carrier foil configured to be attached to a surface of the injection device independent of a geometry of the surface, at least one light emitting diode attached to the flexible carrier foil in a first position and configured to emit a light signal in a direction based on the first position through a transparent wall of the injection device, at least one photodiode attached to the flexible carrier foil in a second position relative to the first position, the at least one photodiode being configured to detect at least a portion of the light signal from a direction based on the second position and being configured to emit an electrical signal based on the light signal to a microprocessor, and wherein the microprocessor is configured to receive the electrical signal emitted by the photodiode and to determine the position of a stopper and the amount of the fluid within the injection device based at least in part on the electrical signal.

Syringe attachments and syringes have particular suitability to the precision dispensing of small amounts of high viscosity materials, such as dermal fillers. An attachment may include a main body having an assist feature that includes a wheel and pinion gears on each side of the wheel which engage respective racks on the syringe body. A mechanical advantage may be provided to the user as the wheel is rotated relative to the syringe body and racks. Syringes and attachments may include precision position indicators viewed from multiple positions to enable a user to determine plunger position and the amount of dispensed contents with precision. An alternative configuration attachment may be slidably secured to a syringe to permit a user to operation the syringe from a lateral position using sliding movement of the thumb and fingers of one hand, for example. This configuration may be particularly suitable for self-administered insulin injections.

A connector (50) includes a tubular member (52) and a base tube (58). A light-guiding tube (60) is drawn out from the base tube (58) toward the opposite side to the tubular member (52). An adapter (1) includes: a first connecting portion (10) that can be connected to and disconnected from a light source device (70); a second connecting portion (20) that can be connected to and disconnected from the connector (50); and a light-guiding member (30) that guides light emitted from the light source device (70) to a proximal end surface (61) of the tube (60).

An injection device kit for the self-administration of an injection of solution that includes a body portion configured for engagement with a cartridge containing the solution and an injection needle where the body portion includes an injection component having an actuation mechanism for inserting the injection needle of the cartridge and for injecting the solution in the cartridge and a safety mechanism on the body portion and configured to prevent injection unless released.

Apparatus and method are described employing pressurized gas to transfer, mix and/or reconstitute medicament contained in a vial and flowing it into an injection device. Pressurized gas may be provided by prefilled cartridge.

A blood circuit assembly for a dialysis unit may include an organizing tray, a pair of pneumatic pumps mounted to the organizing tray for circulating blood received from a patient through a circuit including a dialyzer unit and returned to the patient, an air trap mounted to the organizing tray arranged to remove air from blood circulating in the circuit, a pair of dialyzer connections arranged to connect to the inlet and outlet of a dialyzer unit, and a pair of blood line connectors, one inlet blood line connector for receiving blood from the patient and providing blood to the pneumatic pumps and the other outlet blood line connector for returning blood to the patient.

A device configured to deliver a medicament to a user by injection, comprising an injection feedback apparatus configured to apply temperature-based feedback to the user regarding the delivery of the medicament.

A medical system includes an input assembly for receiving one or more user inputs. The input assembly includes at least one slider assembly for providing an input signal. Processing logic receives the input signal from the input assembly and provides a first output signal and a second output signal. A display assembly is configured to receive, at least in part, the first output signal from the processing logic and render information viewable by the user. The second output signal is provided to one or more medical system components. The information rendered on the display assembly may be manipulatable by the user and at least a portion of the information rendered may be magnified.

A fluid cassette, for example, a blood treatment cassette having a cassette body embodied as a hard part and, optionally, a film which is connected to the hard part and at least partially covers the hard part, wherein the hard part comprises at least one first alignment device, and a second alignment device which are optionally arranged at first and second opposite sides of the fluid cassette or are attached thereon. The disclosure relates in addition to a blood treatment apparatus.
