Abstract
The auditory meatus air-blowing plug of hard fibre ear endoscope, it relates to internal ear checkout facility technical field.It comprises otoscope (5) in auditory meatus plug body (1), endotoscpe channel (2), breather (3), two-phase air-blowing ear ball (4), hard fibre, the centre of described auditory meatus plug body (1) is interspersed with endotoscpe channel (2), endotoscpe channel (2) be plugged with otoscope in hard fibre (5), the outside of auditory meatus plug body (1) is plugged with breather (3), and the outside of breather (3) is connected with two-phase air-blowing ear ball (4) by connection tube.The advantage that it gathers in conjunction with the high definition imaging of hard fibre ear endoscope and image/video, to the observation under the high definition of the trickle pathological change of middle ear and data collection under coordinating earplug realization synchronously to change auditory meatus boost pressure.
Description
Technical field:
This utility model relates to internal ear checkout facility technical field, is specifically related to the auditory meatus air-blowing plug of hard fibre ear endoscope.
Background technology:
Traditional air blast otoscope utilizes natural lamp light source or medical light source, the change that ear canal pressure observes tympanum form is given, directly to reflect the change of tympanum motion conditions, ossicular chain mobility, middle ear volume, indirectly to reflect the situation of internal ear sound conduction function and the flowing of internal ear lymph by balloon.
Traditional air blast otoscope imaging effect is subject to the restriction of amplification and light source, change trickle in structure is difficult to differentiate, and lacks video acquisition function simultaneously, cannot preserve objective materials, although a small amount of product is with picture collection function, image definition is nowhere near.
Although existing hard fibre endotoscpe has imaging clearly, and there is the function of image, video capture collection, still can not realize giving ear canal pressure in operation simultaneously, the changes such as tympanum motion and middle ear endometrial receptivity cannot be observed.Become a shortcoming in endoscopy of ear.
Utility model content:
The purpose of this utility model is to provide the auditory meatus air-blowing plug of hard fibre ear endoscope, the advantage that it gathers in conjunction with the high definition imaging of hard fibre ear endoscope and image/video, to the observation under the high definition of the trickle pathological change of middle ear and data collection under coordinating earplug realization synchronously to change auditory meatus boost pressure.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: it comprises otoscope in auditory meatus plug body, endotoscpe channel, breather, two-phase air-blowing ear ball, hard fibre, the centre of described auditory meatus plug body is interspersed with endotoscpe channel, endotoscpe channel be plugged with otoscope in hard fibre, the outside of auditory meatus plug body is plugged with breather, and the outside of breather is connected with two-phase air-blowing ear ball by connection tube.
Utility model works principle: when carrying out auditory meatus and checking, auditory meatus plug can be enclosed within hard endotoscpe, play the effect of ear canal, do not affect inspection and the operation of scope simultaneously, simultaneously by the soft matter breather of earplug sidewall and the two-phase air-blowing ball of far-end, the stress test of malleation and negative pressure can be completed in airtight auditory meatus space, the motion conditions of tympanum clearly can be observed by endotoscpe, hydrotympanum situation, with or without labyrinthine fistula, this combination can to adhesive otitis media, secreting type otitis media, tympanosclerosis, the diseases such as labyrinthine fistula carry out auxiliary examination, and the camera system of endotoscpe can be utilized to complete video acquisition.
This utility model has following beneficial effect: the advantage that it gathers in conjunction with the high definition imaging of hard fibre ear endoscope and image/video, to the observation under the high definition of the trickle pathological change of middle ear and data collection under coordinating earplug realization synchronously to change auditory meatus boost pressure.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprises otoscope 5 in auditory meatus plug body 1, endotoscpe channel 2, breather 3, two-phase air-blowing ear ball 4, hard fibre, the centre of described auditory meatus plug body 1 is interspersed with endotoscpe channel 2, endotoscpe channel 2 be plugged with otoscope 5 in hard fibre, the outside of auditory meatus plug body 1 is plugged with breather 3, and the outside of breather 3 is connected with two-phase air-blowing ear ball 4 by connection tube.
Further, auditory meatus plug body 1 adopts silica gel material, made of soft, good to auditory meatus noinvasive, obturation effect; Auditory meatus plug body 1 diameter 15mm, thickness 5mm, endotoscpe channel 2 diameter 1.2mm, breather 3 diameter 0.5mm
Utility model works principle: when carrying out auditory meatus and checking, auditory meatus plug can be enclosed within hard endotoscpe, play the effect of ear canal, do not affect inspection and the operation of scope simultaneously, simultaneously by the soft matter breather of earplug sidewall and the two-phase air-blowing ball of far-end, the stress test of malleation and negative pressure can be completed in airtight auditory meatus space, the motion conditions of tympanum clearly can be observed by endotoscpe, hydrotympanum situation, with or without labyrinthine fistula, this combination can to adhesive otitis media, secreting type otitis media, tympanosclerosis, the diseases such as labyrinthine fistula carry out auxiliary examination, and the camera system of endotoscpe can be utilized to complete video acquisition.
This utility model has following beneficial effect: the advantage that it gathers in conjunction with the high definition imaging of hard fibre ear endoscope and image/video, to the observation under the high definition of the trickle pathological change of middle ear and data collection under coordinating earplug realization synchronously to change auditory meatus boost pressure.
