Description

Portable medical headlight of otolaryngology branch of academic or vocational study

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a medical headlight of portable otolaryngology branch of academic or vocational study.

Background

The organs of the otolaryngological department are mostly positioned at the deep parts of the skull and the maxillofacial region, and particularly, when the ears and the nose are examined, the internal structures can be observed through narrow and tortuous tube cavities, so the examination must be carried out by means of special illumination and examination devices.

The inspection device who commonly uses is the frontal mirror, as shown in fig. 1, the frontal mirror is a circular spotlight concave mirror, the mirror surface diameter is about 8cm generally, concave focal length is about 25cm, concave mirror central authorities have a round hole about 1.4cm of a diameter, during the inspection, need shine light to the concave mirror of frontal mirror on with the help of external light source, the concave mirror shines corresponding inspection position behind the light focus, the doctor monocular observes through the round hole of concave mirror central authorities, the direction that can guarantee the sight like this keeps unanimous with the direction that the concave mirror focuses on, but there are several drawbacks in the adoption frontal mirror inspection: firstly, an external light source is needed, and when the patient is in consultation at the bedside or is in outdoor inspection, the patient cannot be inspected without the light source; secondly, when patients with different heights are examined, the position of the light source and the direction of the frontal mirror need to be adjusted repeatedly, so that the use is inconvenient; when the forehead mirror is used, a doctor needs to keep the sight line capable of penetrating through the central circular hole of the concave mirror and consistent with the direction of light reflected by the concave mirror, and the sight line and the light reflected by the concave mirror are not enough to enable the doctor to peep related structures clearly, so that the doctor can use the forehead mirror proficiently by training for a month or even a longer time.

At present, the clinical LED headlight that begins to use gradually replaces the frontal mirror, as shown in fig. 2, its advantage is from area illumination, portable and use, can break away from the restriction of external light source, but because the lamp holder portion divide into solid, the centre does not have the peephole, make the light direction can't keep the complete unanimity with the sight direction of doctor's eyes, can have a little contained angle, this does not have the influence when examining open position, but when otolaryngology branch of academic or vocational study need pass through narrow and small pipelines such as duct, nasal cavity inspection deep position, can lead to when the light can shine the deep, the sight can only see the lumen lateral wall and can't see the deep structure, when the sight aims at the deep, the light can only shine the lumen lateral wall again and can't shine the deep structure, the structure of corresponding inspection is located the position of lumen deepening, this kind of drawback is more obvious.

Therefore, a portable medical head lamp for the ear-nose-throat department is provided.
