Abstract
An instrument for measuring a dilatation of cervix uteri during the first stage of labor. The instrument has two elongated legs pivotally connected to each other. Each leg has a proximal end and a distal end; the top end has an attaching device that can be attached to an inner surface of the cervix. The lower end of one leg is secured to a scale and the lower end of the other leg can move along this scale as the cervix dilates.
Claims20
An apparatus for measuring the cervical dilation during the first stage of labor, comprising:
- a first and a second legs pivotally secured together by a pivot at an intermediate point to allow relative pivoting movement, each leg having a first end and a second end;
- a first attaching device secured to the first end of the first leg;
- and
- a second attaching device secured to the first end of the second leg,
- wherein, after the first attaching device and the second attaching device being attached to opposite lips of a cervix, dilation of the cervix causing the second end of the second leg to move away from the second end of the first leg, thus providing a visual indication of dilation of the cervix.
A method for measuring dilation of a cervix during the initial stage of labor using a measuring device with pivotally a first leg and a second leg, comprising the steps of:
- attaching the first leg of the measuring device to an inside lip of the cervix;
- attaching the second leg of the measuring device to an opposition position on the inside lip of the cervix;
- reading a distance between the first leg and the second leg;
- and
- obtaining a measurement of dilation based on the distance read.
An apparatus for measuring the cervical dilation during the first stage of labor, comprising:
- a first and a second elongated means pivotally secured together by a pivot at an intermediate point to allow relative pivoting movement, each elongate means having a first end and a second end;
- a first attaching means secured to the first end of the first elongate means;
- and
- a second attaching device secured to the first end of the second elongated means,
- wherein, after the first attaching means and the second attaching means being attached to opposite lips of a cervix, dilation of the cervix causing the second end of the second elongated means to move away from the second end of the first elongated means, thus providing an indication of dilation of the cervix.
