Description

[Detailed description of the invention] This invention relates to an amnionoscope, which is used to observe the amniotic fluid properties through the uterine membrane during delivery or at the end of pregnancy. The tip of the tube is hollow, or the tip of the tube is closed into a flat or spherical shape, but if it is hollow, it is complicated to use a separate mandolin to fill the hollow when inserting the lens tube.
After the mandoline was removed, there was a risk of rupture of the egg membrane. Also, closed flat or spherical objects reflect illumination light from the front,
It made it difficult to see inside the uterine cavity and amniotic fluid.

In addition, the lighting bulb is a device that is fixed inside the lens tube via a cord etc. after pulling out the mandoline after inserting the lens tube, so that the lens tube can be inserted into the dimly-lit uterine cavity with only external illumination. required skill.

The present invention has been improved to solve these difficulties and to make it easier to use even during busy times.

To explain with an example, a dry battery 1 is used as a power source,
A threaded part 4 to which a nut 3 can be attached is provided at the tip of the battery tube/handle 2, and a socket 5 for a small light bulb and a light bulb 6 are connected to the tip. A notch 8 is provided in the lens barrel 7 with a width narrower than that of the socket, and the lens barrel and the battery barrel/handle can be easily fixed by inserting the notch 8 into the threaded portion and rotating and tightening the nut.

In addition, since the light bulb is connected to the socket and fixed along the inner wall of the lens barrel, it is possible to illuminate the inside of the uterine cavity from the tip when inserting the lens barrel, and to safely insert the tube while observing the surrounding area.

In addition, the lens barrel is made of a transparent material made of glass or resin, and the lid 9 at the tip is not perpendicular to the long axis direction of the barrel.
Cut and glue at an angle that will not reflect light from the bulb. Therefore, there is no need for a mandoline or the like when inserting the device, and the amniotic fluid can be observed by directly applying the tip to the uterine membrane while excluding surrounding blood and body fluids.

In addition, by processing the lid adhesion surface smoothly without any edges, there is no risk of rupture of the ovarian membrane, which is the case with a cylindrical cut, and the lid is safe.

Claims (1)

[Claim for Utility Model Registration] This is an amnioscope consisting of a lens barrel to be inserted into the uterine cavity, a light bulb connected to it that emits light, and a battery tube and handle.The tip of the lens barrel is cut diagonally and its surface is A transparent flat lid is adhesively molded onto the lens barrel, allowing the outside of the lid to be seen from inside the lens barrel. In addition, to connect the lens barrel and the battery barrel/handle, a socket and light bulb are provided at the tip of the battery barrel/handle, a part of the lower part is made into a neck shape, a thread is cut, a nut is attached, and the nut is tightened. An amniotic mirror whose structure allows the lens barrel to be fixed between the socket and the light bulb by moving it toward the socket.
