Description

Mouth mirror

Technical Field

The utility model relates to a mouth mirror, in particular to disposable mouth mirror.

Background

The stomatoscope is a medical detection instrument commonly used in the ophthalmology and otorhinolaryngology. At present, stainless steel stomatoscope which is frequently used in China and is reused in disinfection, and disposable simple plastic stomatoscope are commonly used. Disposable stomatos are relatively more hygienic, but both of these stomatos do not have a light source and are inconvenient to inspect.

Chinese patent CN203591242U discloses a disposable stomatoscope with a light source, which is structured such that a central rod with a light source at its head is inserted into a hollow handle (connecting rod) with a mouth lens, the tail end of the central rod is provided with a power supply and a switch, and the light source projects light through the light-colored and light-transmitting handle.

The main disadvantages of the stomatoscope are: the whole connecting rod can be illuminated by the light source, so that visual interference is generated when a doctor checks, and the checking is influenced; the central rod with the light source is too thin, the central rod is not combined with the connecting rod when not used at ordinary times, and the central rod is easy to damage and lose after being stored independently.

Disclosure of Invention

An object of the utility model is to overcome prior art's above-mentioned defect, provide a mouth mirror that illumination intensity is strong, the doctor of being convenient for observes.

The technical solution of the utility model is that: the multifunctional glasses comprise a handle with a power supply, wherein the front end of the handle is connected with a center rod through an interface, the front end of the center rod is provided with a light source, a connecting rod with a mouth lens at the head is sleeved outside the center rod, an opening is formed in the end part, close to the mouth lens, of the hollow part of the connecting rod, and the lens seals the opening.

The utility model discloses a lens that the light source passes through the connecting rod front end is projected mouthful camera lens and is reflected away again, and its illumination intensity is stronger than prior art, makes the doctor see the target site clearly more easily. The end part of the connecting rod is provided with a lens to seal the opening, so that the internal central rod can be prevented from being polluted.

The utility model discloses a further technical solution is: the connecting rod is made of light-proof or light-transmitting materials.

In this way, the shaft portion does not visually interfere with the examination by the doctor.

The utility model discloses a further technical solution is: the handle with the power supply adopts a handle part which is universal for the existing handheld medical detector.

The light source of the universal handle part of the existing handheld medical detector (ophthalmoscope and otoscope) has the characteristics of stable color temperature and strong illumination intensity, and the handle can bring a high-quality light source for the mouth mirror.

The utility model discloses a further technical solution is: the central rod is connected with the connecting rod through a pin and a guide groove.

The connecting structure has the advantages that the positioning of the central rod and the connecting rod is accurate, and the combination and the separation of the central rod and the connecting rod are convenient.

Drawings

The following will further explain the details of the present invention with reference to the drawings and examples.

FIG. 1: the structure of the embodiment is schematically shown.

FIG. 2: perspective view of the present embodiment.

FIG. 3: the structure of the connecting part between the center rod and the connecting rod is schematically shown in the embodiment.

Detailed Description

As shown in the figure, this embodiment includes handle 1 with power, and there is well core rod 2 at the front end of handle 1 through interface connection, is equipped with light source 21 at well core rod 2's front end, and the outside cover of well core rod 2 is equipped with connecting rod 3 of head area mouth camera lens 31, and the tip that connecting rod 3 hollow portion is close to mouth camera lens 31 is equipped with opening 32, and this opening 32 department is lived in the lens 4 closure. Wherein the connecting rod 3 is made of opaque or weakly transparent material. Wherein the handle 1 with the power supply adopts the handle part commonly used by the prior handheld medical detector. The central rod 2 and the connecting rod 3 are connected through a pin 22 and a guide groove 33.

Wherein the pin 22 is located at one end of the central rod 2 far from the light source 21, the guide groove 33 is located at one end of the connecting rod 3 far from the lens 31, and the opening of the guide groove is opened at the end surface, and the guide groove 33 has a first guide groove part 33a parallel to the axis of the connecting rod 3 and a second guide groove part 33b connected to the end of the first guide groove part 33a and perpendicular to the first guide groove part 33 a. The width of the first and second

guide slot portions

33a, 33b is slightly greater than the diameter of the pin 22. A projection 331 is provided at a position near the distal end of the second portion 33b of the guide groove, and the projection 331 narrows the width of the second portion 33b of the guide groove at the portion of the projection 331, which is slightly smaller than the diameter of the pin 22.

Therefore, when the central rod is combined with the connecting rod, the pin on the central rod enters the guide groove of the connecting rod, certain acting force is applied to deform the peripheral material of the guide groove, and the pin passes through the bulge of the second part of the guide groove and finally enters the tail end of the second part of the guide groove. Finally, the pin is locked at the tail end of the guide groove, and the combination of the central rod and the connecting rod is realized.

In the embodiment, the handle 1 is connected with the central rod 2 by utilizing the connecting interface at the front end of the handle of the existing handheld medical detector. For this purpose, the central rod 2 is provided with a coupling head 23 at the coupling end with the handle 1. The front end of a handle of the existing handheld medical detector is provided with an interface so as to replace different detection parts and realize different detection functions. Commonly used detection sections are an ophthalmoscope detection section and an otoscope detection section. The interface can simultaneously realize the functions of connecting with an external connector and supplying power to the external connector. The interface between the handle and the detecting part in the prior art is mature technology, and the structure thereof is known in the prior art.

The utility model discloses a mouth mirror establishes the connecting rod cover of taking mouthful camera lens in the outside of well core rod when using to make pin and guide way cooperation hookup. After the connecting rod is used, the connection between the pin and the guide groove is operated reversely, so that the connecting rod is separated from the central rod. The link with the ported lens can then be discarded.
