Abstract: Compressive plates of the placental insertion site for use in cases of placenta previa includes: an axle plate including a primary plate which is fixed, a threaded bar that has machined two plates and a diameter reduction section, a secondary plate having a hole with a diameter and a shape that allows the introduction of the bar, a punch with conical tip, a nut and a locknut, and a protective cover. The punch pierces the front and back walls of the uterus corresponding to the placental insertion site. Then, the secondary plate is introduced that approaches to the primary plate until obtaining enough pressure to stop the bleeding, the nut and locknut are placed, and, finally, the protective cover is screwed.

Abstract: Provided are examples of a hands-free level to quickly, accurately, and efficiency level and plumb a wide range of objects regardless of shape. The level includes a stationary component, an adjustable component, a level device attached to the stationary component/adjustable component, and a cord. The cord includes a J-shaped terminus that abuts the adjustable component. Advancing the cord urges the adjustable component towards the stationary component. Complementary locking teeth on the cord and stationary component lock the adjustable component in place and clamps the hands-free level to an object. This lets a user use two hands to hold and move the object while simultaneously checking the object for plumb and/or level.
