Abstract
The present disclosure provides a pressure-depending clutching device for locating and safely positioning a needle in a body cavity. The device is capable of automatically engaging and disengaging the needle from a driving force. The device has a body with an interior space, a pressure-sensing element and a force-receiving element. The pressure-sensing element, the force-receiving element, and the complementary force-sending element form a driving force engaging mechanism for coupling the force-applying structure to the needle during operation. Before the needle reaches the target body cavity, the pressure in the needle causes the clutching device to assume an 'engaged' state. When the needle reaches the body cavity, the change in pressure causes the clutching device to assume a 'disengaged' state, thereby, automatically positioning the needle in the cavity to avoid overshooting. Also provided are needle-and-syringe assemblies incorporating the disclosed clutching devices, methods for manufacturing the disclosed clutching devices.
