Securement devices, systems, and methods

Abstract

An intraosseous access system can include a hub coupled to a cannula that can be introduced into a bone of a patient. The system further includes a securement device that can couple with the hub when transitioned from an open orientation to a closed orientation. The securement device includes a first segment and a second segment that are spaced apart from each other when the securement device is in the open orientation and are approximated and secured to each other when the securement device is in the closed orientation. The first segment includes a first receptacle that receives a portion of the hub therein and contacts the hub to restrain movement of the hub relative to the securement device when the securement device is coupled with the hub in the closed orientation. The first segment also includes a first arm coupled to the first receptacle, the first arm biasing the first receptacle toward the hub when the securement device is coupled with the hub in the closed orientation.

1 . A system comprising:
 a hub;   a cannula coupled to the hub, the cannula comprising a distal end configured to be introduced into a bone of a patient to provide fluid communication between an interior of the bone and the hub; and   a clamp configured to transition from an open orientation to a closed orientation, the clamp comprising:
 an elongated first branch that comprises a first end, a second end, and a receptacle spaced from the first and second ends; 
 an elongated second branch that comprises a first end and a second end; and 
 a hinge coupled to the first ends of the first and second branches, 
 wherein the first branch transitions from a relaxed state to a flexed state when the clamp is transitioned to the closed orientation with at least a portion of the hub being positioned between the first and second branches and being positioned in the receptacle of the first branch, and 
 wherein the first branch remains in the flexed state while the clamp is maintained in the closed orientation. 
   
     
     
         2 . A system comprising:
 a hub;   a cannula coupled to the hub, the cannula comprising a distal end configured to be introduced into a bone of a patient to provide fluid communication between an interior of the bone and the hub; and   a clamp configured to transition from an open orientation to a closed orientation, the clamp comprising:
 an elongated first branch that comprises a first end and a second end; 
 an elongated second branch that comprises a first end and a second end; 
 a hinge coupled to the first ends of the first and second branches; and 
 a lock coupled to the second ends of the first and second branches, 
 wherein each of the first and second branches transitions from a relaxed state to a flexed state when the clamp is transitioned to the closed orientation with at least a portion of the hub being positioned between the first and second branches, and 
 wherein when the lock is secured with said at least a portion of the hub positioned between the first and second branches, each of the first and second branches remains in the flexed state. 
   
     
     
         3 . A securement device configured for use with a hub that is coupled to a cannula, the cannula comprising a distal end configured to be introduced into a bone of a patient to provide fluid communication between an interior of the bone and the hub, the securement device:
 being configured to couple with the hub when transitioned from an open orientation to a closed orientation; and   comprising a first segment and a second segment that are configured to be spaced apart from each other when the securement device is in the open orientation and are configured to be approximated and secured to each other when the securement device is in the closed orientation, the first segment comprising:
 a first receptacle configured to receive a portion of the hub therein and contact the hub to restrain movement of the hub relative to the securement device when the securement device is coupled with the hub in the closed orientation; and 
 a first arm coupled to the first receptacle, the first arm being configured to bias the first receptacle toward the hub when the securement device is coupled with the hub in the closed orientation.
