Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In this specification, term " distal end " refers to one end far from operator in surgical procedure；" proximal end " refers in hand
By one end of proximal operator when art operates.
Referring to figs. 1 to 10, the utility model first embodiment provides a kind of disposable laryngeal mask 100, including proximally to
The sequentially connected connector 110 of distal direction, conduit 120 and inflatable cover 130, the connector 110 are equipped with perforative first and inflate
Chamber 111, the first respiratory cavity 112 and the first diversion cavity 113；The conduit 120 is internally provided with perforative second inflatable chamber 121,
Two respiratory cavitys 122 and the second diversion cavity 123；The inflatable cover 130 is double-layer structure, is equipped with and is connected to inside the double-layer structure
Air-filled pore 131 and perforative third respiratory cavity 132 and third diversion cavity 133；
First inflatable chamber 111, the second inflatable chamber 121 and the docking of air-filled pore 131 form filling channel 101, described to fill
Gas channel is used to be 130 inner inflatable of the inflatable cover；First respiratory cavity 112, the second respiratory cavity 122 and third respiratory cavity
132 docking form the respiration channel 102 of disposable laryngeal mask；First diversion cavity 113, the second diversion cavity 123 and third water conservancy diversion
Chamber 133 docks the flow-guiding channel 103 for forming disposable laryngeal mask；
The conduit 120 is ellipse, second inflatable chamber 121, the second respiratory cavity along the section in vertical length direction
122 and second the section of diversion cavity 123 be round and be disposed adjacent two-by-two that second respiratory cavity 122 is close to the ellipse
One end of shape long axis, and the center of second respiratory cavity 122 is located on the elliptical long axis.
The filling channel of the present embodiment is located at the inside of laryngeal mask conduit, avoids and filling channel is individually arranged outside conduit
And additionally increase stimulation of the laryngeal mask to user throat；Directly filling channel is formed in catheter interior it is possible to prevente effectively from inflation is logical
Phenomena such as gauffer or distortion, occurs when in use for road, to ensure that safety that laryngeal mask uses；By filling channel, respiration channel
It is disposed adjacent two-by-two with flow-guiding channel so that it is compact-sized in laryngeal mask conduit, so as to effectively reduce laryngeal mask size, to
So that laryngeal mask can be adapted for the patient that such as baby child's throat dimension is smaller.
Further, as shown in Figures 1 to 5, the connector 110 includes the operation portion positioned at proximal end, and laryngeal mask is in use, institute
Operating position is stated in user's oral external, the opening 116 of 113 proximal end of the first inflatable chamber is located on the operation portion；Institute
It further includes gas tube 140 to state disposable laryngeal mask 100, and the material of the gas tube 140 is PVC, and the gas tube 140 is plugged in institute
In the opening 116 for stating 113 proximal end of the first inflatable chamber.
This programme makes gas tube using PVC material, the size of gas tube can be effectively reduced, so as to accordingly reduce
The size of filling channel then reduces laryngeal mask size.
Further, the disposable laryngeal mask further includes the pilot balloon 150 for being connected to 140 proximal end of gas tube.
Further, further include on the operation portion respiratory cavity connector 115 being connected to 112 proximal end of the first respiratory cavity,
