DEVICE FOR MEASURING INTRACRANIAL PRESSURE IN NEWBORNS AND BABIES AND A SUPPORTING MEMBER FOR SAID DEVICE
First Claim
1. A device for measuring intracranial pressure in newborns and babies, comprising a body, a supporting member having a leveling surface at the end thereof, a movable bush with said supporting member secured coaxially thereon, said movable bush being disposed in the body for limited reciprocation to apply static load to the bregmatic fontanel, a rod having a flat base and disposed in the cavity of the movable bush for movement relative to the supporting member and producing an impact force to deform the bregmatic fontanel, a system causing said rod to move, said system having at least one measuring winding connected to a control, processing, and display unit adapted to convert a signal it receives from the measuring winding to determine intracranial pressure and display the results obtained, wherein the supporting member has on the outer surface thereof a limiter of bregmatic fontanel deformation by static load, the leveling surface of the supporting member extending beyond the contact surface of said limiter, said contact surface being inclined to a plane normal to the axis of the movable bush and tangent to the leveling surface of the supporting member with increasing distance therefrom to said plane in the direction toward the periphery of the limiter of bregmatic fontanel deformation by static load.

Abstract
The invention relates to medicine. The inventive device for measuring intracranial pressure in newborns and babies comprises a body, a supporting member with a leveling surface on the end face thereof, a movable bush which is provided with the supporting member coaxially attached thereto and which bush is arranged in the body so as to be capable of carrying out a limited reciprocating motion to produce a static load on the bregmatic fontanel, a rod with a flat base which is accommodated in the movable bush cavity so as to be capable of moving with respect to the supporting member and producing an impact action for deforming the bregmatic fontanel, a rod moving system provided with a measuring coil which is connected to a control, processing and display unit for converting a signal received from the measuring coil in order to determine the intracranial pressure and display the obtained results. The supporting member is designed in the form of a bush with a leveling surface on the end face and is provided on the outer side with a limiter of the deformation produced by the static load on the bregmatic fontanel, the leveling surface of the supporting member is projected beyond the contact surface of the limiter, wherein said contact surface is inclined to a plane which is tangent to the leveling surface in such a way that a distance between the contact surface and the tangent plane increases in the direction towards the periphery of the limiter of the deformation produced by the static load on the bregmatic fontanel.
