Embodiment Construction

[0052] The detailed content and technical description of the present invention will be further described with examples, but it should be understood that the examples are only for illustration and should not be construed as limitations on the implementation of the present invention.

[0053] see Figure 3 ~ Figure 5 , the present invention discloses an oral speculum (10), comprising: an upper palate holding part (11) and a tongue suppressing part (12) which are integrally formed of polyvinyl chloride plastic material (PolyVinyChloride; PVC) and have considerable hardness. ), the palate supporting portion (11) is connected to one end of the tongue depressing portion (12), and the other end is not connected, so that the palate supporting portion (11) and a tongue depressing portion (12) ) can be opened and closed. In this embodiment, the contours of the upper palate holding portion (11) and the tongue pressing portion 12 are roughly in the shape of a parabola. A soft pad (13) fo...

Abstract

The invention relates to a rigid oral cavity opening device. By means of the rigid oral cavity opening device, the upper and lower palates of an oral cavity can be opened stably at an appropriate angle to make an opening device swallowed into the throat and prevent drooling, and the opening angle can be adjusted; the problem can be solved that in the prior art, a soft oral cavity opening device can be swallowed into the throat along with opening and closing of the mouth of a patient, or the hands of nursing staff are bitten by the teeth; the oral cavity opening device abuts against the upper palate of the oral cavity of the human body and opens the upper and lower teeth with a tongue, the opening angle can be adjusted, and the situation is avoided that since the patient suddenly closes themouth, swallows the device into the throat and spits the device out, the hands of the nursing staff are bitten by the teeth; meanwhile, without relaying on the teeth as support objects, the teeth cannot be shielded, and the dental operation is not affected.

Description

(1) Technical field: [0001] The present invention relates to an oral speculum, in particular to a rigid oral speculum capable of stably stretching the upper mouth and lower palate at an appropriate angle, avoiding saliva flow and swallowing the speculum into the throat, and being able to adjust the stretching angle. (two) background technology: [0002] Generally, when medical personnel treat the patient's oral cavity, teeth or throat, the patient has to open his mouth wide. After a long time, the patient's saliva flows continuously. The main reason is that the masseter muscles are tense, and the speed of salivation increases. They may have to rinse their mouth many times and feel tired. It is easy to bite the hand of the medical staff when the mouth is suddenly closed due to pain or tension, especially when the mouth is under local anesthesia, the patient loses control, and often the muscle tension causes the sudden closure of the mouth and the teeth bite the hand of the med...
