  • Patent number: 9278164
    Abstract: A negative pressure wound therapy system creates a negative pressure environment in the opening of a wound-dressing unit and a positive pressure environment in the collecting bag. Then a positive pressure detecting procedure is proceeded in the positive pressure environment and a negative pressure detecting procedure is proceeded in the negative pressure environment. The detecting results are sent to determine whether a micro pump is stopped.

  • 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.

  • 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.

  • Publication number: 20110009784
    Abstract: A compression device for medical treatment includes an upper colloid sheet, a lower colloid sheet, and a plurality of gas ports. The upper colloid sheet is stacked with the lower colloid sheet and welded, so as to form a plurality of isolated cells with welded walls, and each cell respectively corresponds to one of the gas ports. Therein, the welded walls that neighbors each cell extend diagonally along an angle that is between an x-axis direction and an y-axis direction, so that the welded walls extends from an edge of the upper colloid sheet and the lower colloid sheet to another edge of the upper colloid sheet and the lower colloid sheet. Per aforementioned, the compression device for medical treatment has diagonally formed cells, which results in compression from two directions, so that the medical benefits are increased.

  • Publication number: 20030002902
    Abstract: This invention relates to a keyboards with a track operation key, comprising a track located at a proper position of the keyboard. In the track, there is an operation key that can move along the track, and there is also a sensor used to detect the displacement of the operation key and then converting to the motion displacement value that can control the curser movement on the screen. Therefore, through moving the operation key in the track it becomes feasible to control the cursor's motion directly. For the track and the operation key, they can be set in vertical or horizontal so as to operate the cursor vertically or horizontally.
