Wherein operate in the pipe portion of pipe end, be provided with ecto-entad can the unidirectional unidirectional valve passing through.The dismountable operation pipe end outside that is arranged on of operation end sealing lid.Gas sampling end seal cover is dismountable to be arranged on gas analysis sampling joint.
Further, respirator jointing, patient end jointing and gas analytical sampling joint all adopt the international standard joint of 1:40 external taper.
Further, operation pipe end is positioned at upper end, and respirator jointing is arranged in right-hand member, and patient end jointing is positioned at lower end, and gas analysis sampling joint is arranged in left end.
When further, operation end sealing lid is arranged on operation pipe end port and between operation pipe end, be tightly connected.When gas sampling end seal cover is arranged on gas analysis sampling joint and between gas analysis sampling joint, be tightly connected.
Further, operation end sealing lid is connected on the tube wall of operation pipe end outside by connecting line, and gas sampling end seal cover is connected on the tube wall of gas analysis sampling joint outside by connecting line.
The utlity model has positive effect: (1) flap valve type of the present utility model breathing circuit three-way device can carry out artificial ventilation support in branchofiberoscope operation, reduce anoxia risk when branchofiberoscope operates, shortened the time of whole operation.
(2) flap valve type breathing circuit three-way device of the present utility model can be applied the general anesthesia mode of muscle relaxant when doing branchofiberoscope manipulation check instead by the general anesthesia that retains autonomous respiration, and in operating process, patient is safer more comfortable.
(3) flap valve type breathing circuit three-way device of the present utility model is widely used flexibly, its patient end jointing can connect face shield, laryngeal mask or endotracheal tube etc., can not take off the operation of pipe suction sputum and cause not anoxia in various General anesthesias or on band respirator patient; Also the situation that can be used for needing one-lung ventilation and insert bronchial occlusive device.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Labelling in above-mentioned accompanying drawing is as follows:
Operation pipe end 1, unidirectional valve 1-1, respirator jointing 2, patient end jointing 3, gas analysis sampling joint 4, operation end sealing lid 5, gas sampling end seal cover 6.
The specific embodiment
(embodiment 1)
See Fig. 1, the flap valve type breathing circuit three-way device of the present embodiment comprises operation pipe end 1, respirator jointing 2, patient end jointing 3, gas analysis sampling joint 4, operation end sealing lid 5 and gas sampling end seal cover 6.Wherein, respirator connects head 2 for connecting respirator and anesthetic machine, patient end jointing 3 is for connecting face shield, laryngeal mask or endotracheal tube, gas analysis sampling joint 4 is for gas analysis sampling, and respirator jointing 2, patient end jointing 3 and gas analytical sampling joint 4 all adopt the international standard joint of 1:40 external taper.Operation pipe end 1, respirator jointing 2, patient end jointing 3 and gas analytical sampling joint 4 are connected and are linked together by its pipe portion tail end, form operation pipe end 1 and are arranged in upper end, respirator jointing 2 and are arranged in right-hand member, patient end jointing 3 and are positioned at the integral piece that lower end, gas analysis sampling joint 4 are positioned at left end.
Wherein operate in the pipe portion of pipe end 1, be provided with ecto-entad (in Fig. 1 for from top to bottom) can the unidirectional unidirectional valve 1-1 passing through.
Operation end sealing covers 5 dismountable operation pipe end 1 outsides that are arranged on, and operates between end sealing lid 5 and operation pipe end 1 and adopt tight fit connection in the present embodiment, when operation end sealing lid 5 is arranged on operation pipe end port one and between port one, is tightly connected.
Gas sampling end seal cover 6 is dismountable to be arranged on gas analysis sampling joint 4, in the present embodiment, between gas sampling end seal cover 6 and gas analysis sampling joint 4, adopt and be threaded, when gas sampling end seal cover 6 is arranged on gas analysis sampling joint 4 and between gas analysis sampling joint 4, be tightly connected.
