Abstract
Disclosed is a non-reusable intra-osseous access device and method thereof. The non-reusable intra-osseous access device which can be easily rendered non-reusable after establishing the access into the marrow region includes the automatic locking of driver unit 5 after removal of needle and trocar assembly from the driver unit. Further, the non-reusable intra-osseous access device also includes the non-loading of the trocar and or needle hub and or trocar with needle hub.
Claims19
A non-reusable Intraosseous (IO) device comprising:
- a handle capable of being displaced by applying force, the handle comprising a spring-clutch and an inner barrel;
- a multi-splined axial shaft engaged with a multi-spiral nut and is capable of being rotated, the multi-splined axial shaft comprising an axial hollow cavity and at least one opening;
- a needle hub comprising at least one needle;
- and
- when the handle is displaced axially down, it compresses the spring-clutch and engages with the inner barrel, thereby enabling the multi-spiral nut to move axially down, and rotating the multi-splined axial shaft, thereafter transferring the rotational motion and axial thrust to a trocar holder and the needle hub, and enabling access through an injection site by a rotational piercing action;
- wherein
- an automatic locking mechanism, operating after enabling access through the injection site, comprising:
- at least one expandable element, the trocar holder comprising a trocar and a trocar holder shaft, wherein the trocar holder is inside the multi-splined axial shaft with the trocar holder shaft inside an axial hollow cavity and during assembled condition the expandable element is locked inside a hollow cavity of the trocar holder, wherein
- the expandable element is configured to protrude outside the opening preventing axial up-down motion of the multi-spiral nut along the multi-splined axial shaft rendering the non-reusable Intraosseous (IO) device non-reusable;
- and
- at least one spring or at least one spring eyelet configured to press the expandable element to protrude outside the opening preventing axial up-down motion of the multi-spiral nut along the multi-splined axial shaft rendering the non-reusable Intraosseous (IO) device non-reusable post insertion.

A non-reusable Intraosseous (IO) device comprising:
- a handle capable of being displaced by applying force, the handle comprising a spring-clutch and an inner barrel;
- a multi-splined axial shaft engaged with a multi-spiral nut and capable of being rotated, the multi-splined axial shaft comprising a tearable pouch filled with adhesive material in an axial hollow cavity and at least one opening;
- a needle hub comprising at least one needle;
- and
- when the handle is displaced axially down, it compresses the spring-clutch and engages with inner barrel, thereby enabling the multi-spiral nut to move axially down, and rotating the multi-splined axial shaft, thereafter transferring the rotational motion and axial thrust to a trocar holder and the needle hub, and enabling access through an injection site by rotational piercing action;
- wherein
- an automatic locking mechanism, operating after enabling access through the injection site, wherein the trocar holder and needle hub are configured to be dismantled thereby leading to prevention of the rotation of the multi-splined shaft and making the device non-reusable, by breaking the tearable pouch causing the liquid adhesive within the tearable pouch to ooze out of the opening, wherein one end of the tear-able pouch is attached to one end of the trocar holder shaft.
