Abstract

The utility model discloses a backward tension ruler that is invented in order to solve the problems that the existing medical measuring apparatus can not effectively and accurately measure the straight-line distance between palatoglossal arches and between two palatopharyngeal arches and the like. The backward tension ruler comprises: a ring, a left tong arm, a right tong arm, a connecting shaft and a tong head, as well as a measuring scale. The measuring scale is fixed on the left tong arm or the right tong arm. The backward tension ruler is simple in structure, convenient for operation and accurate in measuring the data between palatoglossal arches and between two palatopharyngeal arches.

Description

The anti-chi of opening

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of anti-chi.

Background technology

Neither one is specially at the gauge of air line distance between two palatoglossal arch, two palatopharyngeal arcies in the known present medical apparatus and instruments, a lot of medical workers are to use plastic strip or paper slip to stretch into the oral cavity, only depend on vision to judge distance between two palatoglossal arch, two palatopharyngeal arcies, such method is not only required great effort, and the distance between two palates is judged and inaccuracy, caused to provide a report accurately the patient.

The utility model content

The purpose of this utility model provides a kind of simple to operate, practical and convenient, anti-chi of opening that can accurately read air line distance between two palatoglossal arch, two palatopharyngeal arcies, has solved existing two palates and has measured the inaccurate problem of effort.

In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:

A kind of anti-chi comprises: finger ring, left clamp arm, right clamp arm, connecting axle and binding clip; Described anti-chi also comprises dip stick, and described dip stick is fixed on left clamp arm or the right clamp arm.

Wherein, described dip stick is an arc line type, and the camber line that produced of the radian of dip stick during with left clamp arm, right clamp arm opening and closing is identical.

Further, dip stick is the hollow ring type structure, and the graduated scale of dip stick is arranged on the inner loop-line.

Further, described right clamp arm or left clamp arm are provided with location parts, and the position of described positioning element is corresponding with the graduated scale position of aforementioned dip stick.

The beneficial effect of spatula described in the utility model is: install and measure on left clamp arm or the right clamp arm being provided with of chi and each position of dip stick can effectively help the medical worker convenient, read air line distance between two palatoglossal arch, two palatopharyngeal arcies accurately, and this utility model is simple to operate, practical and convenient.

Description of drawings

Fig. 1 is this utility model embodiment sketch map.

The specific embodiment

Below in conjunction with Figure of description the specific embodiment of the present utility model is done detailed description.Obviously, described embodiment only is a part of embodiment of the present utility model, and other embodiment that those skilled in the art is obtained under the prerequisite of not paying creative work belongs to protection domain of the present utility model.

As shown in Figure 1, a kind of anti-chi comprises: finger ring 1, and left clamp arm 2, right clamp arm 3, connecting axle 4 and binding clip 5 also comprise dip stick 6, described dip stick 6 is fixed on left side pincers 2 arms or the right clamp arm 3; Described dip stick 6 is an arc line type, and the camber line that the radian of dip stick 6 produces during with left clamp arm 2, right clamp arm 3 opening and closing is identical; Described dip stick 6 is the hollow ring type structure, and the graduated scale 7 of dip stick 6 is arranged on the inner loop-line; Described right clamp arm 3 or left clamp arm 2 are provided with location parts 8, and the position of described positioning element 8 is corresponding with graduated scale 7 positions of aforementioned dip stick 6.

Wherein, the unit of described dip stick is mm and cm.

During use, when the patient dehisces (sending out " " sound) in self-heating, hands of medical worker uses spatula to push down tongue body, the finger of another hands is controlled the anti-chi of opening by finger ring, anti-opening opened binding clip after chi stretches into the oral cavity, and binding clip touch palatoglossal arch, pharyngopalatine arch respectively, air line distance between two palatine arches can directly read on the dip stick by an anti-chi rear end, makes the data that measure more accurate by positioning element.

More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
