  • Publication number: 20230397806
    Abstract: An apparatus for diagnosing and treating cervical precancer includes a handheld colposcope comprising a camera and screen configured to view and generate an image of a cervix. A thermal ablation probe is incorporated into the handheld colposcope and is configured to apply heat to the cervix in response to detection of cervical precancer by the handheld colposcope. In certain embodiments, a lens of the camera is positioned to visually assist in placing the thermal ablation probe onto the cervix. In certain embodiments, the handheld colposcope is further configured to recognize, using artificial intelligence or other algorithms, one or more of the cervix in the image, whether the cervix comprises precancerous lesions, and the stage of any precancer. A corresponding method is also disclosed.

  • Patent number: 11555816
    Abstract: A method is taught for the accurate determination of the premature rupture of membranes (PROM), defined as spontaneous rupture of membranes before the onset of uterine contractions. More specifically, a lateral flow assay strip tests for at least two antigens to greatly limit or eliminate the possibility of false negatives. A built-in timer in the cassette holding the lateral flow assay further increases the accuracy of the test. A collection buffer vial with self-contained shipping and dropper caps and built-in stand is also taught.

  • Publication number: 20210038281
    Abstract: A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal's electrical characteristics, such as operating frequency, duty cycle, peak voltage, and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.

  • Publication number: 20110034776
    Abstract: A vaginal speculum adapted to be positioned within a vagina has a hollow cylindrical body with means integral therewith for distending the vagina internally of the introitus, whereby the speculum allows visualisation of, and access to and through the cervix, without distending the cervix. In one embodiment the hollow cylindrical body has an inner and outer tube, which are movable relative to each other along the longitudinal axis of the hollow cylindrical body between a first position, wherein the distending means is closed and a second position, wherein the distending means is distended. In this embodiment the distending means is a plurality of elongate members connected between the distal ends of the inner and outer tubes. In the first position the elongate members lie along the longitudinal axis of the hollow cylindrical and in the second position they are bent out from the hollow cylindrical body as the distance between the distal ends of the inner and outer tubes has been shortened.

  • Publication number: 20020165556
    Abstract: A vacuum assisted fetal extraction apparatus and a monitoring device for use in conjunction therewith. The monitoring device includes a circuit including a timer operably coupled with a switch, which may comprise a differential pressure sensor. The switch is configured to be actuated by the formation of a vacuum to secure the fetal extractor to a fetus. At least partial release of the vacuum releases the switch to stop or pause the timer. The timer may be configured to be reset such that it only records or displays the duration of a specific application of the vacuum device, or it may be configured to record or display a cumulative duration based upon multiple applications of the vacuum device in an absolute sense or during a defined time period. Magnitude as well as the cumulative number of applications of an applied vacuum may also be measured and, optionally, displayed, as may the number of times traction force is applied to an infant during delivery.

  • Patent number: 6355047
    Abstract: A vacuum extractor for use in childbirth is described. The vacuum extractor includes a handle and a vacuum cup with a force sensor coupled to the vacuum extractor. The force sensor measures the traction force applied between the vacuum cup and the handle for assisting the birthing attendant in applying an appropriate traction force. The force sensor may also include a slipping mechanism which causes the length of the force sensor to distinctly increase if the applied traction force exceeds a certain level such as twenty pounds. Thus, the birthing attendant may feel the slipping and thus determine that the traction force has exceeded the certain value.

  • Patent number: 6074399
    Abstract: A hand-held fetal vacuum extractor combines a pump and handle into a single hand-held unit. This enables a single operator, such as a doctor, to control vacuum using a vacuum pump, and apply traction to a fetus using a single hand. A handle, having a surface for gripping, is connected to a fetal vacuum cup for being suctioned onto a fetal head. A vacuum pump is connected to the handle and includes an activation surface for activating the vacuum pump. The vacuum pump is fluidly coupled to a the vacuum cup and fetal head. The grip surface of the handle and the activation surface of the pump are in such proximity, during operation, that a single human hand can simultaneously grasp the grip surface and contact the activation surface.

  • Patent number: 6059795
    Abstract: The fetal contact cup portion of a fetal vacuum cup has an inside surface which, when applied to a fetal head, defines a fetal contact chamber with the fetal head. One end of a tube is attached to the fetal contact cup such that vacuums within the tube are applied within the fetal contact cup. The other end of the tube can be connected with a vacuum source and with a handle. The tube has a very small average outside diameter compared with conventional fetal vacuum tubes. Thus the fetal vacuum cup is less intrusive during insertion and is more easily maneuverable, especially when the fetus is malpresenting in, for example, the high occipitoposterior or high occipitolateral positions. The average outside diameter of the tube may be, for example, less than 150 mils and has a finger grip that compression fits into a recess defined by the outer surface of the fetal contact cup for a lower profile and easy positioning of the fetal contact cup onto the flexion point of the fetal head.
