  • Patent number: 5251613
    Abstract: A simple yet highly useful cervical videoscope has been provided which can easily be used by the doctor to examine the cervix and vagina for cancerous lesions or other abnormalities. Also, because of the small size of the video camera unit there is sufficient space between the video camera unit and the blades of the speculum for inserting forceps and other instruments that may need to be used. By using the cervical videoscope in combination with a monochromator the physician can step the wavelength of light from one end of the light spectrum to the other until he observes florescence which identifies abnormal cells. Thereupon, he can destroy the cells by use of a laser beam. When he observes that no more florescence,is occurring, then he can discontinue the operation of the laser, knowing that the lesion has been completely eradicated. Also, a channel for drawing a suction to remove smoke created by the destruction of the lesion can be provided.

  • Patent number: 4362246
    Abstract: A method of treating mammal semen for use in artificial insemination is provided. Human saliva is added to the semen as an anti-coagulant. For mammals other than primates and voles, sperm-free human semen is added to the mammal semen as a cell membrane diffusion material so that a dye such as quinicrine or quinicrine mustard will be absorbed by the Y chromosome. The semen is then fed in a narrow stream through a detection chamber where it is irradiated with ultraviolet light causing the Y chromosomes to fluoresce. The stream is fed from the detection chamber through a fluidic amplifier wherein the stream is switched in response to whether the detected chromosome is fluorescent or non-fluorescent so that the fluorescent Y chromosome is directed through one outlet port and collected and the non-fluorescent X chromosome is directed through a second outlet port and collected.
