  • Patent number: 9107987
    Abstract: A tube coupling of a phlegm suction tube, which is capable of connecting two injectors having different mating structures, includes a tube body and a tube connector. The tube body is hollow and has a coupling end and a check valve. The tube connector is coaxially connected to the coupling end of the tube body and has a joint portion. The joint portion has a passage communicating with the tube body. The check valve flexibly closes the passage from the tube body. A diameter of the passage fits a first injector with a first mating structure, and an outer diameter of the joint portion fits a second injector with a second mating structure.

  • Patent number: 7895898
    Abstract: A negative pressure gauge includes a body and a multi-stage positioning means. The body is provided with an airflow passage. The multi-stage positioning means includes a rotary piece and a cover plate. The rotary piece is pivotally connected to the body and is provided with positioning recesses and venting troughs. The cover plate covers the rotary piece and is fixedly connected to the body. The cover plate extends to form a positioning protrusion corresponding to the positioning recesses. When the rotary piece rotates with respect to the cover plate, the positioning recesses allow the positioning protrusion to be selectively positioned therein and control the communication or obstruction between the venting troughs and the airflow passage.

  • Patent number: 7798009
    Abstract: A negative pressure gauge includes a body, a positioning means, a display model, a power-supplying unit and a switch. The positioning means has a rotary piece pivotally connected to the body. The rotary piece is formed with a trigger protrusion. The display model is fixed to the body. The power-supplying unit is fixed to the body and electrically connected to the display model via an electrical line. The switch is mounted in the body and arranged to correspond to the trigger protrusion of the rotary piece. The switch is mounted on the electrical line. In normal state, the switch generates a broken circuit between the display model and the power-supplying unit. When the rotary piece rotates with respect to the body, the switch will be triggered by the trigger protrusion, so that the power-supplying unit and the display model are electrically connected to each other. Via this arrangement, the display model can be turned on or off selectively to save the electricity.

  • Publication number: 20090231120
    Abstract: An integrated apparatus for a medical alarm system includes modules and functions of both area alarm units and master alarm units. An input/output module is provided to specify functions of the area alarm units and master alarm units when the two functions are separately executed. In addition, functions of both area alarm units and the master alarm units can also be operated in an integrated apparatus. The execution programs of the integrated apparatus can be updated and modified by connecting the integrated apparatus to an external memory card. Therefore, the integrated apparatus saves not only disassembling and assembling time, but also costs of update operation.

  • Publication number: 20090212940
    Abstract: A method of a wireless alarm for a medical alarm system, and the alarm system is installed with a network module and a cell phone module. An alarm signal is remotely transmitted to a computer or a portable apparatus by the network module on Internet or is remotely transmitted to a cell phone of by the cell phone module through a GPRS when an unusual environmental condition is detected by the alarm system. This method enhances alarm efficiency of the alarm system.

  • Publication number: 20090088602
    Abstract: A sheath structure of portable medical equipment includes a protecting shell, a snap-on body, a container, and a sheath. The protecting shell has two shell bodies corresponding to each other. At one side of the shell bodies, a first snapping part and a second snapping part are arranged, and a jointing hole is arranged at the front side of the second snapping part. The snap-on body has a main body jointed to the jointing hole and arranged a ring groove at the front side thereof. The container includes a first cup and a second cup. An opening is respectively arranged at one side of a first bulger and a second bulger, each of which is belonged to the first and second cups, while a projecting wall is respectively arranged at another side. When the first cup and the second cup have been assembled, an accommodating space is formed between the first bulger and the second bulger, and the sheath is contained in the accommodating space with one side positioned in the ring groove.
