Detailed Description of Preferred Embodiments
Figures 1-3 show a handheld portable medical viewing assembly 10 including an adapter 11 for mounting a handheld portable digital camera 12 having a housing 13 with a telescopic objective lens 14 and a display screen 16 on a handheld portable laryngoscope 17 with a handle 18, a blade 19, and an optical system 21 with an eyepiece 22 having an optical axis 23 for viewing a subject's laryngeal region during endotracheal intubation. A suitable digital camera is the Premier Digital Camera DS-5341 having a telescopic objective lens retracted inside its housing when powered down (see Figure 4), and having a maximum outward protrusion of about 25 millimeters (see Figure 5). A suitable laryngoscope is commercially available from the Applicants under the trade name
TRUVIEW™ http://www.truρhatek.com/default.php?p=products&pl=2&ρ2=88.
The adapter 11 includes a body member 24 for directly aligning the objective lens 14 with the eyepiece's optical axis 23 in the assembled state of the medical viewing assembly 10. The body member 24 is dimensioned not to impede the telescopic movement of the objective lens 14 in its most outwardly protruding position in the assembled state of the medical viewing assembly (see Figure 5). The body member 24 includes a first tubular body component 24A and a second tubular body component 24B. The body component 24A is preferably permanently mounted on the housing 13 to encircle its objective lens 14. The body component 24A can be glued on the housing 13, screwed on, and the like. The body component 24B connects the laryngoscope , 17 to its counterpart body component 24A and consequently the digital camera 12. The body component 24B has a proximal side 26A and a distal side 26B. The proximal side 26A connecting the body component 24B to the body component 24A typically uses a screw thread, a bayonet connection, and the like. The distal side 26B preferably has magnets for magnetic attraction with a suitable metal eyepiece. Other connection arrangements include a bayonet connection, and the like. The use of the medical viewing assembly 10 is as follows: A user attaches the body component 24A to the housing 13 to encircle the objective lens 14. The user mounts the body component 24B on the body component 24A to assemble the adapter 11. The user mounts the adapter 11 on a laryngoscope's eyepiece 22 whereupon the user can view medical images displayed on the display screen 16. The user can use the digital camera 12 for taking still and/or video images, and the like.
Figure 6 shows a handheld portable medical viewing assembly 10 including an adapter 31 similar to the adapter 11 but formed from a pair of L- shaped flange members 32A and 32B for defining a U-shaped channel 33 for secure mounting on a housing and a tubular aperture 34 for secure mounting on an eyepiece 22 on screw clamping the L-shaped flange members 32A and 32B together.
Figures 7-9 shows an intubation stylet 51 made from a rolled metal strip of shape memory material, for example, spring steel, and the like, having a rectangular cross section. The intubation stylet 51 has a generally J-shaped elongated member 52 with a longitudinal axis 53, and a rectangular transverse cross section perpendicular to the longitudinal axis 53 with major front and rear surfaces 54A and 54B and minor side surfaces 56A and 56B (see Figure 8). The rectangular transverse cross section affords flexibility in the Y-Z plane and rigidity in the X-Z plane for facilitating successful first attempt intubations. The elongated member 52 includes a hand held trailing portion 57, a generally straight intermediate portion 58, and a pre-bent arcuate leading portion 59 with a leading tip 61 curled back upon itself. The leading portion 59 has opposite ends 59 A and 59B defining an arc length in the order of about 15 cm and a chord length CL of about 13 cm for an adult sized intubation stylet 51. The intermediate portion 58 preferably is formed with a V-shaped cross section in the X-Y plane to afford greater rigidity in the Y-Z plane (see Figure 9). The generally straight intermediate portion 58 may be formed with a circular cross section in the X-Y plane. Alternatively, only the pre-bent arcuate leading portion 59 may be formed from shape memory material and suitably attached to an intermediate portion 58 made from non-shape memory material by soldering, and the like.
Figure 10 shows an intubation stylet 62 similar to the intubation stylet 51 and additionally having a fiber optic cable 63 connected to a light source 64 and terminating at its leading tip 62A for illuminating a subject's laryngeal region during endotracheal intubation. Figure 11 shows an intubation stylet 66 similar to the intubation stylet 51 and having an electrical powered light source 67 at its leading tip 66A connected to a power supply 68 via an electrical wire 69 for illuminating a subject's laryngeal region during endotracheal intubation. Figure 12 shows an intubation stylet 71 similar to the intubation stylet 51 and additionally having a tube 72 having an opening 72A at the stylet's distal end 71 A in flow communication with either an oxygen source 73 for delivering oxygen to a subject during an endotracheal intubation or a suction pump 74 for removing undesirable liquids from a subject's tracheal region during endotracheal intubation.
