Abstract: An infusion device includes a fluid path module and a drive module. The fluid path module includes a first housing and a peristaltic pump disposed within the first housing and including a flexible tube and a roller module. The roller module includes a holder structure movable laterally, a roller mechanism and an actuating rod. The roller mechanism is rotatably mounted on the holder structure. The actuating rod drives the roller module to rotate. The drive module includes a second housing, a spinning head and a power source. The spinning head and the power source are disposed within the second housing. The power source rotates the spinning head. When the actuating rod is at an initial position, the flexible tube is uncompressed. When the second housing is assembled with the first housing, the spinning head becomes engaged with the actuating rod and the roller mechanism compresses the flexible tube.

Abstract: An injection device includes an injection body and an adaptor. An injection end and a non-injection end are defined at opposite sides of the injection body. The injection body includes an injection member, a drug storage member, a movable member and a driving mechanism. The injection member is located at the injection end and in fluid communication with the drug storage member. The movable member is disposed in the drug storage member. The driving mechanism is located at the non-injection end and engaged with the movable member. The adaptor is detachably assembled to the injection end. When the driving mechanism rotates in a first direction, the movable member linearly moves along a longitudinal axis of the drug storage member toward the non-injection end. When the driving mechanism rotates in a second direction, the movable member linearly moves along the longitudinal axis of the drug storage member toward the injection end.

Abstract: A communication network for monitoring node state within a chain based network that includes a first base-station configured to transmit a ping signal and a plurality of nodes each configured to receive the ping signal, send an acknowledgement signal upon receipt of the ping signal and transmit the ping signal. The communication network also includes a second base-station configured to receive the ping signal and transmit data related to the plurality of nodes based on the ping signal.

Abstract: A drug delivery device includes a drug container, an peristaltic pump, an orientation sensor, an alarm unit and an operation processor. The peristaltic pump is connected to the drug container and adapted to deliver a therapeutic substance of the drug container into an subject. The orientation sensor is adapted to sense orientation of the drug container relative to gravity. The operation processor is adapted to acquire a first angle boundary and a second angle boundary greater than the first angle boundary corresponding to the drug container, and further to maintain delivery of the peristaltic pump and actuate the alarm unit in response to the orientation greater than the first angle boundary but smaller than or equal to the second angle boundary, and further to pause the delivery of the peristaltic pump in response to the orientation greater than the second angle boundary.

Abstract: A pumping and inserting mechanism is provided and includes a pumping assembly, a driving assembly and an inserting assembly. The pumping assembly includes an input portion and an output portion. The driving assembly is coupled to the input portion of the pumping assembly and configured to drive a rotating movement of the input portion of the pumping assembly to drive a rotating movement of the output portion of the pumping assembly. The inserting assembly includes a triggering component and an inserting component. The triggering component is driven to rotate to trigger an inserting movement of the inserting component in response to the rotating movement of the output portion of the pumping assembly. Besides, a related automated injection system is also provided.

Abstract: A cartridge holder adapted for a cartridge body and a plunger of a cartridge assembly is provided and includes a holding component, a first cooperating component, a second cooperating component and a resilient component. The holding component is configured to accommodate the cartridge assembly. The first cooperating component is mounted on the holding component and immovable relative to the holding component. The second cooperating component is movable relative to the first cooperating component and configured to be driven to rotate to disengage from the first cooperating component. The resilient component is disposed between the first cooperating component and the second cooperating component and configured to drive the second cooperating component to push the plunger to slide relative to the cartridge body along a first direction after the second cooperating component is driven to rotate to disengage from the first cooperating component. Besides, a related injection system is also provided.

Abstract: A peristaltic pump device includes a casing, a flexible tube, and a roller module. The flexible tube is disposed within an accommodating space of the casing and has a curved tube portion. The roller module is rotatably disposed within the accommodating space and surrounded by the flexible tube and includes a holder structure movable relative to the curved tube portion, a roller mechanism rotatably mounted on the holder structure, and an actuating rod. The actuating rod is movable upward and downward relative to the curved tube portion. A protruding structure protrudes laterally from at least one of the holder structure and the actuating rod. When the actuating rod moves downward, the protruding structure interferes with another of the holder structure and the actuating rod for moving the holder structure to make the roller mechanism compress the curved tube portion by a lateral, rotational, or tilted movement of the holder structure.

Abstract: A drug delivery device includes a casing, a drug infusion member, an injection member, a sensing module and a processing unit. The drug infusion member is disposed in the casing. The injection member is disposed in the casing and connected to the drug infusion member. The sensing module is disposed in the casing and configured to sense statuses of the drug infusion member and the injection member. The processing unit is disposed in the casing and coupled to the sensing module. When the processing unit determines that a medical fluid is filled in the drug infusion member in response to the sensing module, the processing unit selectively controls the injection member to be exposed from the casing.
