Abstract: The present invention relates to a gynecological device (1) comprising a body part (2) having a vacuum chamber (3), a rod unit (4) with a distal end, a proximal end, and a channel (41) extending between the distal end and the proximal end, a cervix head (5) arranged at the distal end of the rod unit (4), and a sealing mechanism (6) configured to switch between an ambient state and a vacuum state. The rod unit (4) extends to the vacuum chamber (3) of the body part (2) such that the proximal end of the rod unit (4) is located in the vacuum chamber (3) of the body part (2). The cervix head (5) is configured to engage a section of a cervix from a vaginal side. When in the ambient state of the sealing mechanism (6), the vacuum chamber (3) of the body part (2) is sealed and the channel (41) of the rod unit (4) is open to an exterior (7) of the gynecological device (1).

Abstract: The connecting end of the hypodermic needle is so designed that it can be attached to and then disconnected from the tip of an injection instrument by pressure, that is, an axial tractional force exerted between the said needle and the said injection instrument. The extraction device has an opening delimited by locking elements forming one piece with elastic pieces so as to allow its diameter to vary between a minimum diameter and a maximum diameter at least equal to the diameter of the said connecting end and at least one piece associated with the said locking elements for the purpose of converting an axial force exerted on the said piece into at least one radial component capable of being applied to the said elastic pieces so as to deform them radially in order to increase the diameter of the said opening when axial pressure is exerted by the said connecting end.

Abstract: The connecting end of this storage container for at least one hypodermic needle has connectors complementary to the connectors on the tip of an injection instrument, one of the connectors having radial elasticity and devices for converting an axial force exerted between the needle and the injection instrument into at least one radial component which can deform the elastic connectors. The container has a housing fore the needle designed to hold this needle in a given position and an opening giving access to the housing. The shape and dimensions of the exterior wall bounding the housing are selected to create with the needle an ergonomic positioning and/or handling interface so as to facilitate the connection of the complementary connectors of the needle and the tip, respectively.

Abstract: The invention provides an injection device comprising an open cavity, an injection needle projecting from the bottom of this cavity, a first leakproof compartment delimited by a first section of a mobile barrier, first devices for displacing the said first section of a mobile barrier to vary the volume of the compartment, at least one passage communicating between the said first leakproof compartment and the said cavity, a second leakproof compartment for a product to be injected, delimited by a second section of a mobile barrier, and second devices for displacing the said second section of a mobile barrier to vary the volume of the compartment. The said first and second leakproof compartments extend longitudinally within a tubular body. The cavity is located at one end of this tubular body, while the said first and second devices for displacing the said first and second sections of a mobile barrier are accessible at the other end of the said tubular body.
