Abstract
There is provided an apparatus for extraction of at least one object from a cavity. The apparatus includes a sleeve including an inflatable section configured to surround the at least one object during inflation; a handle configured to enable a user to hold the sleeve, the handle defining a holding edge of an opening at a first portion of the sleeve; and a handle-mount mounted to a peripheral area around the opening, the handle-mount being for attachment of a pump used for inflating the inflatable section. There is also provided a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit.
Claims1
A method of using a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit, the method comprising:
- applying a positive pressure to thereby inflate an inflatable section of the birth assistance device, wherein the inflatable section is inflated by a pressure limited pump comprising a central chamber for receiving and containing a gas, a first check valve allowing air to pass therethrough and into the central chamber and preventing back flow of air out of the central chamber, a second check valve allowing air to pass therethrough and out of the central chamber and preventing back flow of air into the central chamber, the central chamber including a compressible portion having a compressible volume and an incompressible portion having an incompressible volume, wherein the compressible portion and the incompressible portion remain in fluid communication and wherein a ratio of the incompressible volume and the compressible volume defines a pressure of the air passing through the second check valve;
- and compressing the compressible portion of the central chamber such that air flows into the inflatable section of the birth assistance device.
