Problems solved by technology

In medicine, the circumference of the uvula is used to judge whether the uvula is too thick. Different people have different shapes of the uvula. The uvula is an inverted cone with a thick top and a thin bottom, which requires multiple measurements at different positions of the uvula, and the uvula is located in the narrow mouth and deep in the pharyngeal cavity, which makes its measurement difficult. Specialized tools are effective for measuring the circumference of the uvula in the mouth

Embodiment 1

[0025] Such as figure 1 , 2 As shown, the present embodiment provides a tool for measuring the circumference of the uvula in the mouth, including a main rod 1, a soft ruler 2, and a sliding scale 3. An axial passage is arranged in the main rod 1, and a section of sliding rod 6 is slidably arranged in the axial passage. The rear end side of the rod 1 is provided with a slideway 11 and the scale lines distributed axially from the rear to the front. The slide mark 3 can be slidably installed in the slideway 11. The front end of the soft ruler 2 is connected with the front end of the main rod 1. The rear end of the soft ruler 2 The end penetrates the main rod 1 from the axial passage and is connected with the front end of the sliding rod 6, and the other end of the sliding rod 6 is connected with the sliding mark 3; Fixed connection, the rear end edge of the sliding sleeve 4 is the scale marking line, when the sliding sleeve 4 drives the sliding mark 3 to slide backward until the...

Embodiment 2

[0030] In the uvula circumference measurement tool in embodiment 1, when the soft ruler 2 is too soft, all of it is received in the main rod 1, which may cause the soft ruler 2 to be unable to be released when it is used next time. In order to solve this problem, this embodiment improves its structure, Such as Figure 4 As shown, the scale line is translated 1 cm backward along the main rod 1 relative to the slideway 11, and the corresponding scale indication at the rear end edge of the slideway 11 is the initial scale. When the sliding sleeve 4 drives the sliding mark 3 to slide backward to the scale When the marking line corresponds to the initial scale, the front end of the soft ruler 2 will form a small trap with the same perimeter as the initial scale outside the main rod 1; the zero scale of the scale line exceeds the rear end of the slideway 11, and the sliding sleeve 4 and When the slider 3 slides to the rear end of the slideway 11, a part of the soft ruler 2 is expose...

Embodiment 3

[0032] This embodiment also improves the problem that the soft ruler 2 is too soft to push out, such as Figure 5 , 6 As shown, an L-shaped support block 7 is arranged at the front end of the main rod 1, and one end of the support block 7 is rotatably connected to the front end of the main rod 1. After the measurement is completed, the support block 7 is transferred to the ring formed by the soft ruler 2 , and then slide the slider 3 backwards, the front end of the tape 2 is tightened on the support block 7, and the doctor pulls the tape 2 from the support block 7 to assist in pushing out the tape 2 during the next measurement.

Abstract

The invention provides a tool for measuring the circumference of the uvula in the mouth, which includes a main rod, a soft ruler, and a sliding scale. The rear end side of the main rod is provided with a slideway and a scale line distributed axially from the back to the front. The sliding scale can be slidably installed on the In the slideway, the front end of the soft ruler is connected to the front end of the main rod, and the rear end of the soft ruler penetrates axially from the front end of the main rod and is connected with the sliding mark. When the sliding mark slides backward to correspond to the zero scale line, all the soft ruler Thread into the main pole and straighten. The tool for measuring the circumference of the uvula in the mouth provided by the present invention converts the circumference of the loop formed by the soft ruler around the uvula into the distance that the slider walks along the slide, so that the medical staff can directly read the measurement length on the main rod. The utility model has the advantages of simple structure, convenient use and accurate measurement, and is especially suitable for one-time multi-point circumference measurement of inverted cone uvula.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a measurement tool for the circumference of the uvula in the mouth. Background technique [0002] The uvula is the downward protruding part of the free edge of the soft palate in the oral cavity. It is a round columnar shape when viewed with the naked eye. When the uvula is too thick, it will occupy the space of the pharyngeal cavity, resulting in a narrow pharyngeal cavity, causing foreign body sensation in the pharynx and upper airway resistance. Obstructive sleep apnea, such as increase, suffocation, hypoxia, etc., will threaten life safety in severe cases. In medicine, the circumference of the uvula is used to judge whether the uvula is too thick. Different people have different shapes of the uvula. The uvula is in the shape of an inverted cone with a thick top and a thin bottom, which requires multiple measurements at different positions of the uvula, an...
