  • Patent number: 9730661
    Abstract: A triple three-way valve device comprises: a valve body (1) having a distal end and a proximal end, wherein the proximal end of the valve body (1) is connected with a control knob (2) that is radially rotatable relative to the valve body (1); and a valve rod (3) having a distal end and a proximal end, wherein the valve rod (3) is provided within the valve body (1) and is fixedly connected with the control knob (2). The distal end of the valve body (1) is connected with a seat body (4), which is connected with a plurality of liquid passages and a high pressure pipe passage; a selection member (5) provided at the distal end of the valve body (1), wherein, depending on the position of the control knob (2), the selection member (5) selects the communication relationships between the plurality of liquid passages of the seat body (4), the high pressure pipe passage and the valve rod. With the triple three-way valve device, angiocardiography surgery is simplified, and surgery safety and efficiency are improved.

  • Publication number: 20160089295
    Abstract: In one example, an apparatus for positioning a patient's forearm during a medical procedure has a main panel portion, an extended panel portion and a base panel portion. The main panel portion has an inner surface and an outer surface, a first longitudinal side edge, a second longitudinal side edge, a first latitudinal side edge and a second latitudinal side edge. The extended panel portion has panel portion having a proximal end edge and a distal end edge, and an inner surface, wherein said distal end edge forms an angled configuration with said main panel portion for positioning the patient's left forearm and wrist suitably for receiving an arterial catheter. The base panel portion has a first longitudinal side edge and a second longitudinal side edge, wherein said first longitudinal side edge of said base panel portion extends generally perpendicularly outward from said second longitudinal side edge of said main panel portion.

  • Publication number: 20140301867
    Abstract: A balloon pressure pump comprising a cavity (1) having a distal end and a proximal end; a push rod (2) having a distal end and a proximal end, and provided with an external thread and inserted into the cavity; a handle (3) fixedly connected with the proximal end of the push rod (2); a locking member (4) having a distal end and a proximal end and arranged on the proximal end of the push rod (2) and used to lock same; the distal end of the locking member (4) is fixedly connected with the proximal end of the cavity (1). The handle (3) is internally provided with a sleeve (5) to accommodate the push rod (2); said sleeve (5) is fixedly connected with the proximal end of the locking member (4). The proximal end of the push rod (2) includes a spring (11) which is enclosed within the sleeve. The simple structure of the pump simplifies operations such as pressure application, pressure relief, negative pressure evacuation and the like, and is greatly convenient for a user.
