Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
It should be noted that, during the operation of the video laryngoscope, the end close to the operator is defined as the "near end", and the end far away from the operator is defined as the "far end".
Referring to fig. 1 and 2, a first embodiment of the invention provides a video laryngoscope with replaceable blades, which comprises a handle 1, a camera 2 and a blade 3; the handle 1 comprises a first sleeve 11 and a second sleeve 12, the first sleeve 11 is provided with a first inner cavity 11a with an opening positioned at a distal end, the second sleeve 12 is provided with a second inner cavity 12a with an opening positioned at a proximal end, the first sleeve 11 and the second sleeve 12 are sleeved in a sliding manner along the axial direction, so that the length of the handle 1 is adjustable, the first inner cavity 11a and the second inner cavity 12a are communicated to form an accommodating cavity 1a, and the accommodating cavity 1a is used for accommodating a power supply system and a light source system; the camera 2 is connected with a power supply system and a light source system through a wire penetrating from the far end of the second sleeve 12; blade 3 has the radian with patient's pharyngeal curvature matched with, and it has the opening and is located the third inner chamber 3a of near-end, wears camera 2 and handle 1 to establish in proper order from the opening part of third inner chamber 3a back in the third inner chamber 3a, the near-end of blade 3 can be dismantled and connect in the near-end of handle 1.
The sleeving length between the first sleeve 11 and the second sleeve 12 can be adjusted according to the specification of the blade 3, so that the length from the camera 2 to the near end of the handle is adjusted, and the camera is always arranged at the far end of the third inner cavity 3 a; therefore, the blade can be adapted to blades with different specifications, and the requirements of different patients are met; the blade provided by the invention is sleeved outside the handle and the camera, so that the waterproof and sealing performances of the insertion part of the video laryngoscope are improved, the disinfection and cleaning are facilitated, and the use cost is reduced.
There may be a plurality of slidable coupling means for the first and second sleeves. In this embodiment, the inner diameter of the first sleeve 11 is slightly larger than the outer diameter of the second sleeve 12, the outer wall of the proximal end of the second sleeve 12 is provided with a buckle 121, the inner wall of the distal end of the first sleeve 11 is provided with a plurality of clamping grooves 111 matched with the buckle 121 along the axial direction, and the buckle 121 is clamped in different clamping grooves 111, so that the length of the handle 1 can be adjusted.
