RU1802694C - Expendable vagina mirror - Google Patents

Description

The invention relates to medical equipment and can be used in gynecology.

An object of the invention is to avoid reuse.

Figure 1 shows the cross section of the mirror; figure 2, 3 and 4 are sections, respectively, aa, bb, cc in figure 1; figure 5 is a view of A.

The disposable vaginal mirror contains plates 1 and 2, pivotally connected to each other by axes 3. Plate 1 is continued by a handle 4, in the longitudinal slot of which a slider 5 is installed, having two curly slots in one of which is located a spring 6 self-locking from the plane, and in another knife 7. The plate 2 is inseparably connected with the slider 5 by the thread 8. On the plate 1 there is a hole 9, and on the plate 2 there is a tide 10 corresponding to the hole 9.

The operation of the proposed mirror is carried out as follows.

During gynecological manipulations, the doctor, holding the mirror with the handle 4, inserts into the vagina plates 1 and 2, which are in the reduced state (fixed with the help of the tide 10, which is currently located in the hole 9).

After that, by pressing the knot 5 with a thumb, it moves down the slot in the handle 4. The knot 5 connected to the plate 2 by the thread 8 causes the plate 2 to rotate around the hinge 3 relative to the plate 1. When the angle of separation of the plates 1 and 2 will be sufficient, the movement of the node 5 is stopped. The plane spring 6, bent in the slot of the assembly 5 with some effort, fixes it (and therefore the plates 1 and 2) in this state.

At the end of the work, to reduce the plates 1 and 2 and freely withdraw them from the vagina, they press the knife 7, cut the thread 8, thereby releasing the plate 2, which returns to its original position by the elasticity of the vagina.

The reuse of the mirror is eliminated by the fact that the connection between the plate 2 and the assembly 5 is broken, the fixing assembly 5 allows it to be moved in only one direction, thereby rendering the mirror unsuitable for reuse.

The use of the invention will completely eliminate the possibility of infection by eliminating the reuse of the mirror and significantly increase the ease of use, as it allows the plates to be pulled apart and fixed with one hand in any position and does not require any additional cutting tool to remove the mirror from the vagina .

Claims (2)
