  • Publication number: 20210252502
    Abstract: A microfluidic detection unit comprises at least one fluid injection section, a fluid storage section and a detection section. Each fluid injection section defines a fluid outlet; the fluid storage section is in gas communication with the atmosphere and defines a fluid inlet; the detection section defines a first end in communication with the fluid outlet and a second end in communication with the fluid inlet. A height difference is defined between the fluid outlet and the fluid inlet along the direction of gravity. When a first fluid is injected from the at least one fluid injection section, the first fluid is driven by gravity to pass through the detection section and accumulate to form a droplet at the fluid inlet, such that a state of fluid pressure equilibrium of the first fluid is established.

  • Patent number: 9095644
    Abstract: A fluid collector has a container, a T-tube, a first screw unit and a second screw unit. The T-tube is connected to the container and has a main pipe and a branch pipe. The first screw unit is mounted in an outlet end of the main pipe. The second screw unit is mounted in a connecting end of the branch pipe, which is connected to the main pipe. The branch pipe has a detecting opening far from the connecting end and connects to a detecting device. By changing the length of the first and second screw units, different detecting values of the pressure are adjusted according to containers with different capacities. Moreover, with the flowing resistance resulting from the first and second screw units, different pressure variations are performed when liquid or air passes through the T-tube. Therefore, massive hemorrhage is clearly identified to keep the patient safe.

  • Publication number: 20130317463
    Abstract: A negative pressure wound therapy system has a buffering unit connected between an actuator and a wound dressing. The buffering unit has similar physical condition with the wound, and consumes its negative pressure to compensate for the negative pressure loss in the wound to resist the pressure rise in the wound during slight leakage. The buffering unit also keeps the actuator from directly operating on the wound to reduce the pain of the patient while lowering the pressure in the wound.

  • Patent number: 8303555
    Abstract: A collector for a negative pressure wound therapy system has a soft collecting bag with a gas-permeable unit and a liquid absorber. The collecting bag is connected to a wound-dressing unit via an inlet connecting set and is connected to a sensor assembly via a detecting connecting set. With the soft collecting bag, the collector occupies less volume. By the gas-permeable unit and the liquid absorber, the liquid and gas entering into the collecting bag quickly isolate. Moreover, multiple collectors connect in series to form a collector combination to reduce the frequency to replace the collector combination so that a longer usage time of the collector combination is available.

  • Patent number: 8173078
    Abstract: A microfluidic chip with a built-in gravity-driven micropump is provided. The gravity-driven micropump comprises a winding channel, an inert fluidic material placed inside the winding channel, and a suction channel that links the winding channel to the microfluidic chip. The winding channel is for the inert fluidic material to flow in. A fixed volume of high density, inert fluidic material is placed in the winding channel to act as a micropump in the bio chip. When the microfluidic chip is placed in a declining or standing position, the inert fluidic material flows along the winding channel due to the gravity. The invention provides a simple, convenient, and robust microfluid pumping source. With the built-in micropump, this invention is free-of-pollution and saves the manufacturing cost for the pipe link between the bio chip and peripheral devices.

  • Publication number: 20120053542
    Abstract: An actuator has a pump head detachably connecting to an external motor. When the actuator extracts the pus and the infection subjects, the fluid only flows through the pump head so that only the pump head needs to be made of biocompatibility materials. Therefore, the manufacturing cost is reduced. Moreover, because the motor is not made of biocompatibility materials, only the pump head needs to be treated as medical wastes so that the disposal cost is reduced. Furthermore, since the pump head is detachable from the motor, the infected pump head is replaced independently to lower the replacement cost.

  • Patent number: 7867453
    Abstract: The present invention relates to a gravity-driven fraction separator and method thereof. The gravity-driven fraction separator is substantially a substrate having a microchannel structure arranged thereon, in which the microchannel structure is extending longitudinally on the substrate while sloping with respect to the level of the substrate by a specific angle. As a micro fluidics is being filled in a loading well situated upstream of the microchannel structure, the micro fluidics is driven by gravity to flow downstream in the microchannel structure while filling a plurality of manifolds formed in a area situated downstream of the microchannel structure, so that accurate quantification and separation of the micro fluidics using the plural manifolds, each having a specific length, can be achieved and provided for posterior inspection and analysis.
