Description


BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention


[0002] The present invention relates to a microscopic visualization tube for determining ovulation period. The batteries disposed to the battery seat of the tube can be replaced.


[0003] (b) Description of the Prior Art


[0004] In view of contraception and enhancing fertility, the determination of ovulation period is important. In respect to enhancing fertility, generally, a woman who wishes to become pregnant has two main alternatives. She can either take ovulation-enhancing drugs; or she can predict the time of ovulation and intercourse at that time for the purpose of conception. One method of detecting and timing ovulation that is simple and well known is recording the basal body temperatures when a woman is waking at morning. The method is based on the fact that a rise in temperature indicates that ovulation has occurred.


[0005] Some researchers believe that the best fertile time of an ovum may not be more than 12 hours. However, spermatozoa are thought to be viable up to 72 hours in the female genital tract. For a woman desiring to become pregnant, it definitely would be advantageous to know when ovulation occurs.


[0006] On the other hand, contraception is needed for a woman who does not want to become pregnant. Various natural methods of contraception are referred to as the safe period, this method usually requires that couples abstain from intercourse for at least eight days approximately at midcycle between the menses. It is through that the ovum released from the ovary is susceptible to fertilization for only 12 hours; and that the spermatozoa deposited in the female reproductive tract are capable of fertilizing the ovum for only 72 hours. Thus, if intercourse did not occur just before and during this period, the spermatozoa could not fertilize the ovum and conception could not take place. This in theory is a safe and simple method of contraception.


[0007] However, in practice, the safe period method has some difficulties. If a woman has regular menstrual cycles, then this method is reliable, because she can readily know from the calendar the safe days after and before ovulation and restrict intercourse accordingly. But menstrual and/or ovulation cycles in many women are often irregular, in particular, as a result of work pressure, for example, the menstrual cycle may vary as long as 7 to 13 days for the peak reproductive years and by even greater margins for girls in their teens and women approaching menopause. It is not completely reliable to predict the ovulation time by simply estimating from the estimated next menstrual commence day.


[0008] Accordingly, a portable microscopic visualization tube has been designed to determine the ovulation timing by assaying saliva from a woman. This is a very convenient and reliable device when ovulation has taken place. Thus the device of the present invention is useful for contraception and/enhance fertility.

[0010] The observer holds the beam table 20 and the eyepiece 11 is made close to one eye, the pressing end 33A is triggered to illuminate all the lenses of the microscopic lens module 10 so that the surface of the object lens 12 produces an image. If the image is a dispersed distribution, it is a non-ovulation period. If the image is a crystalline, leave veins distribution, it is an ovulation period. However, the drawbacks of such device are that


[0011] (1) the battery cannot be replaced unless the beam tube 20 is demolished.


[0012] (2) if the battery is exhausted after an extended period of time, it has to be discarded.
