  • Publication number: 20200061306
    Abstract: One embodiment is directed to a safety syringe system, comprising: an off-the-shelf syringe assembly comprising a syringe body and a plunger tip; a needle assembly removably coupleable to the distal end of the syringe body such that medicinal fluid may be transferred through a retractable needle coupled to a needle housing comprising the needle assembly upon insertion of the plunger tip relative to the syringe body; and a plunger control assembly coupled to the plunger tip and configured to facilitate manual insertion of the plunger tip relative to the syringe body; wherein upon insertion of the plunger tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.

  • Publication number: 20190374716
    Abstract: A system for serially injecting liquids includes a syringe body, proximal and distal stopper members disposed in the syringe body, a first liquid in a distal chamber, a second liquid in a proximal chamber, a plunger member, and a needle hub assembly coupled to a distal needle interface of the syringe body. The plunger member includes a needle retention feature disposed in a plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. Manipulating the plunger member to insert the proximal stopper member distally relative to the syringe body initially expels the first liquid, then the second liquid. The needle is at least partially retractable into plunger interior.

  • Patent number: 10219835
    Abstract: An apparatus (10) includes a fastener (16) engageable with a bone portion to connect a longitudinal member (12) to the bone portion. A housing (40) has a first passage (42) configured to receive the longitudinal member (12) and a second passage (44) extending transverse to the first passage. The fastener (16) extends through an opening (50) in the housing (40) into the second passage (44). A longitudinal axis (18) of the fastener (16) is positionable in any one of a plurality of angular positions relative to a longitudinal axis (46) of the second passage (44). A spacer (60) received in the second passage (44) of the housing (40) is engageable with the fastener (16) and the longitudinal member (12). A member (70) applies a force to prevent relative movement between the fastener (16) and the housing (40) and permit manual movement of the fastener (16) relative to the housing (40) against the force when the longitudinal member (12) is disengaged from the spacer (60).

  • Publication number: 20190000437
    Abstract: Systems, devices, and methods suitable for use with procedures performed at least partially percutaneously are provided. In some procedures, two or more access devices for providing access to adjacent surgical locations within a patient are used. Certain embodiments of the access device comprise an elongate body having a distal end with one or more cutouts. The cutouts on adjacent access devices are generally aligned with each other to permit passage of a portion of a fixation element from one access device to the other access device. A fastener with an elongated removable head may be delivered to the surgical site through the access device. After a distal end of the fastener is secured to the surgical site, a portion of the elongated housing is detached from the remainder of the fastener and removed from the patient.

  • Publication number: 20180114288
    Abstract: This disclosure provides an efficient, hands-free system and method for capturing and recording patient data in critical care environments. The systems and methods described herein enables clinicians to record and transcribe patient information onto a disposable medical record tag (akin to a military ID tags), which accompanies the patient throughout initial stabilization and presentation to a treatment center. A Pre-Hospital Treatment & Triage (PHT) guidance system, visible in the HMD, can guide caregivers and/or first responders through treating the patient and documenting a patient's medical condition and treatment status, and triaging patients to the appropriate level of care. The head-mounted display can wirelessly transfer the patient's treatment data to a lightweight disposable data tag, referred to as an electronic TCCC (E-TC3) that is affixed to the patient. The data tag digitally stores a patient's health status, and displays a specific color based on a patient's degree of injury.
