Description

Medical detection device

The invention relates to an improved medical detecting instrument, in particular to a medical detecting instrument provided with a hand-held portion, a display portion and a detecting module.

When a physician performs an intra-, intra-oral or intranasal examination of a patient, it is conventionally performed using a conventional hand-held inspection mirror. The conventional hand-held detection mirror is similar to the structure of a magnifying glass and includes a handle and an observation portion. The front end of the observation portion is a gradually elongated structure, so as to extend into the organ to be inspected, and the end of the elongated structure The point is provided with a lens that magnifies the image inside the organ for observation by the physician.

However, such a conventional hand-held inspection mirror must be placed close to the observation portion and viewed directly from the lens to be able to see the magnified image. However, this method is very likely to cause eye strain of the user (ie, the physician), and thus is not an ideal detection method. Moreover, since the inside of the organ to be inspected is very dark, it is usually necessary to project a light source to make the viewing field clear, which is also an inconvenience of the conventional hand-held detecting mirror. Furthermore, after the physician uses the conventional hand-held inspection mirror to perform an inspection, only the image of the inspection result can be hand-painted on the paper, but there is often an error in the drawing, thereby causing a medical record error.

In view of this, the inventors have provided a medical detecting instrument to overcome the disadvantages of the aforementioned conventional hand-held detecting mirror. Please refer to the cross-sectional illustration of the medical testing instrument as shown in the first figure. The medical testing instrument A10 includes: a body A12 for holding by hand; and a display part A17 provided with a screen A21 A detection part A14 has a lens A30 at the front end thereof, which can be used to extend into the organ to be inspected and capture the image, and convert the image into a digital signal by the image sensing unit A34; a focal length adjusting wheel A24, The focal length of the lens A30 is adjusted by a cable A50; and the plurality of light sources A40 are light-emitting diodes, which can emit a light source and project onto the target through the light guide A46 to increase the visibility of the field of view. The outer casing of the body A12, the display portion A17 and the detecting portion A14 are integrally formed, that is, the three portions are not detachable and detachable.

Since the detecting portion A14 is in contact with the patient's organ every time, the disinfection action must be performed after each use. However, since the medical testing instrument A10 is an integrally formed structure, the detection is performed. Part A14 is an action that cannot be disassembled and disinfected separately, which is very inconvenient. Or when the components inside the detecting portion A14 are damaged, the medical detecting instrument A10 must be integrally removed to be replaced or repaired.

In addition, since the light source A40 must be used to project the light source onto the target by the light guide A46, the transmission of the light source in the light guide A46 is more or less depleted, and the light guide A46 is set. Will increase the cost of the cost.

In view of this, an improved medical testing instrument must be provided to overcome the shortcomings of the prior art.
