1. Field of the Invention
The present invention relates to a cervix examination device capable of containing and separating a light module; more particularly, the present invention relates to a cervix examination device suitable for cervical colposcopy to enable a user to distinguish abnormal cells from normal cells.
2. Description of the Related Art
Conventionally, diagnosis of cervical cancer performed with the cervical smear test, a technique known to have a rather high false negative rate. In order to prevent the above erroneous diagnosis, a popular technique called PAPSURE™, which provides a more accurate and efficient way, is often used in conjunction with the cervical smear test. The accuracy can be increased to more than 90% by the combination of the above two tests.
In order to conduct PAPSURE™, a vaginal speculum needs to be inserted into the vagina to facilitate inspection or medication. In addition, during such an examination, a light source is needed to illuminate the inside of the vagina. Generally, the light source is usually a handheld light projector or a head-wearable light. However, the traditional light source is not convenient and cannot be inserted inside the vagina to provide sufficient illumination; thus, the illumination effect is poor when such traditional light sources are used.
To provide more desirable illumination means, several solutions have been proposed in the related art. For example, a light module is attached to a second open part of a vaginal speculum. Because the light module is placed in the front of the vaginal speculum, the light module can provide illumination with higher efficiency inside the vagina. However, to prevent cross infection, the vaginal speculum and the light module need to be dispensed after used. It is a waste of resources and may increase costs if the light module cannot be reused.
It is therefore an object of the present invention to provide a cervix examination device capable of containing and separating a light module.
It is another object of the present invention to provide a cervix examination set suitable for cervical colposcopy to enable a user to distinguish abnormal cells from normal cells.
To achieve the first object mentioned above, the cervix examination device of the present invention comprises a first blade having a first open part and a first holding part; a second blade, which is pivoted to the first blade, comprising a second open part and a second holding part; an adjuster installed between the first and the second blades for adjusting the relative angle between the first and the second open parts; and a container installed inside the first open part, the container comprising an open portion and a closed portion, the light module can be contained in the closed portion via the open portion.
To achieve another object mentioned above, the cervix examination set of the present invention comprises a first blade having a first open part and a first holding part; a second blade, which is pivoted to the first blade, comprising a second open part and a second holding part; an adjuster installed between the first and the second blades for adjusting the relative angle between the first and the second open parts; a light module for providing illumination; and a container installed inside the first open part, the container comprising an open portion and a closed portion, the light module can be contained in the closed portion via the open portion.
Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The whole light module 70 is contained and separated inside the container 50 to prevent contact with the patient; in other words, the light module 70 can be reused several times without causing cross infection. The light module 70 may comprise without limitation a light bulb and other electrical devices. The light module 70 also can be a fluorescent bar or other illumination objects. In the present embodiment, the light module 70 comprises a light unit 72, a control unit 76, and a switch 78. The light unit 72 is for emitting light. The control unit 76 is for controlling the light unit 72. The light unit 72 is electrically connected to the control unit 76 by a wire 74.
In most situations, the light unit 72 may emit light of a color different from that of the normal cells, preferably green light, which is complementary to the red light reflected by normal cells, so that users may distinguish abnormal cells from normal cells more easily. However, the light unit 72 can also emit other visible light with wavelengths smaller than those of red light, for example and without limitation white light, yellow light, blue light, purple light, etc.
The light unit 70 may comprise a single color or multi-color LED (light emitting diode), or comprise a plurality of LEDs of different colors. The control unit 76 controls on/off and even controls the color of the light emitted by the light unit 72 according to the switch 78, operated by the user. In the present embodiment, the light module 70 is powered by a battery.
In addition, in the present embodiment, the light module 70 has at least one part made of soft material in order to move the light unit 72 to the closed portion 54 easily. Furthermore, the switch 78 has a bump shape such that when the light module 70 is inserted completely into the container 50, the switch 78 will be pressed by the end 112 of the first open part 11, and therefore the light unit 72 will be turned on automatically.

The cervix examination set 60 of the present invention may be applied to both PAPSURE™ and ordinary cervical observations.
In contrast to the prior art, the cervix examination device 1 of the present invention is capable of containing and separating the light module 70 inside the container 50 to prevent the light module 70 from being contaminated, thus preventing cross infection. In addition, the light module 70 of the cervix examination set 60 can be a reusable resource, thus reducing the cost of the cervical examination.
Although the present invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
