Ear speculum inspection method
An Ear speculum is a medical testing device that detects whether there is a disease in the ear. It has the characteristics of rapid detection, thoroughness and safety. Below we will come together to understand the detection method of the Ear speculum, I hope to help everyone.
An Ear speculum is a good way to check. It has its own light source, sound source and magnifying glass. The doctor can clearly see the health of the ear canal through the Ear speculum, and even see the damage of the tympanic membrane. There is echo in the ear, which may be caused by obstruction of the eustachian tube. The eustachian tube cannot be seen by Ear speculum and only the external auditory canal and tympanic membrane can be examined. In this case, you can pinch your nose and help to ease.
The Ear speculum is shaped like a funnel and has a calibre size. When inspecting, the appropriate Ear speculum should be selected according to the width of the external auditory canal. In order to observe the entire appearance of the ear canal and the tympanic membrane.
Ear speculum can be divided into two-handed and one-handed inspection
1. One-handed examination: When examining the left ear, the left thumb and the finger holding the Ear speculum, first push the auricle back and up with the middle finger, and then place the Ear speculum in the external auditory canal. When checking the right ear, the left ear and the finger are still holding the Ear speculum. The middle finger and the ring finger pull the auricle, and the external auditory canal is straightened and the Ear speculum is placed.
2. Two-hand examination method: the examiner pulls the auricle in the left hand and straightens the ear canal as far as possible. The right hand gently puts the Ear speculum into the external auditory canal, so that the front end of the Ear speculum reaches the cartilage part, taking care not to exceed the junction of the cartilage part and the bone part. So as not to cause pain. The direction of the Ear speculum tube axis is consistent with the long axis of the external auditory canal, otherwise the tympanic membrane will not be seen.
The above is about the introduction of Ear speculum detection methods. I hope everyone can understand the Ear speculum detection method and it will help everyone.
