Introducer guide
An introducer guide ( 19 ) for an intubation device ( 21 ) having an open channel adapted to releasably secure an introducer, and shaped such that advancement of an intubation tube ( 21 ) through which the introducer extends causes the introducer to be removed from the introducer guide ( 19 ).
1. Introducer guide means for an intubation device, the introducer guide means having an operating configuration in which the introducer guide means defines an open channel adapted to releasably secure in position an introducer in the open channel, the channel having first and second ends respectively upstream and downstream of the deployment direction of the introducer wherein the first end is shaped to contact an intubation tube so as to cause the intubation tube to remove the introducer from the introducer guide means, the first end comprising a tube deflecting formation in the form of a smooth taper operable to deflect an intubation tube through which an introducer retained in the open channel of the introducer guide means extends as the intubation tube is advanced to engage with the tube deflecting formation.
2. Introducer guide means according to claim 1 , also having a flattened configuration in which one or more members which define the open channel in the operating configuration are folded against a base portion of the introducer guide means.
3. Introducer guide means according to claim 1 wherein the open channel is elongate and is defined by walls, one or more of which are deformable.
4. Introducer guide means according to claim 3 , wherein one or more walls are elastically deformable.
5. Introducer guide means according to claim 3 , wherein one or more walls comprises or consists of a hinged guiding member.
6. Introducer guide means according to claim 1 , wherein the first end of the introducer guide means comprises walls which extend at an angle of less than 60° to the length of the introducer guide means.
7. Introducer guide means according to claim 1 , comprising means for attachment to a suitable medical device.
8. A blade portion of an intubation device and introducer guide means according to claim 1 , said introducer guide means being demountably attachable to or integral to the blade portion.
9. An intubation device and a blade portion according to claim 8 , said blade portion being demountably attachable to or integral to the intubation device.
10. An intubation device according to claim 9 , which is a laryngoscope.
11. A method of intubating a patient, comprising the step of introducing an intubation device according to claim 9 into a patient, with an introducer extending through an intubation tube and the introducer guide means, and then advancing an intubation tube towards the introducer guide means such that the introducer guide means causes the introducer to be removed from the introducer guide means.
12. A kit comprising apparatus according to claim 1 and an intubation tube having a diameter sufficiently large to not extend through the introducer guide means.
