Produce a comprehensive, technically precise list drawn **only** from the provided text (no outside knowledge or unstated inferences).

Identify and list:
    1. Core technical concepts (principles/mechanisms)
    2. Novel features (explicit/implicit distinctions from prior art)
    3. Implementation details (configs, parameters, methods)
    4. Functional advantages (benefits over existing solutions)
    5. Alternative embodiments (variants/options)

For each item include:
    * Significance: why it matters in context
    * Technical function: how it works/interacts
    * Novelty indicators: wording implying uniqueness
    * Dependencies: components/steps it relies on or enables

Always capture parameters precisely:
    * Numerical ranges/values with units and any preferred ranges
    * Material compositions (materials/compounds/formulations)
    * Process parameters (temperatures, pressures, times, sequences, conditions)
    * Structural relationships (connections, arrangements, interactions)
    * Control logic (algorithms, decision/operation sequences)

Guidelines:
    * Be exhaustive; include minor, distinguishing details
    * Preserve exact terminology and conditional language (“may,” “optionally,” etc.)
    * Note stated problems addressed
    * Record any test results, examples, or performance metrics
    * If a technical term is unclear, include it and add a best context-based interpretation (clearly labeled as interpretation)

### Patent Claims/Description:
The present invention is directed to a syringe system for reconstitution of lyophilized or concentrated drugs. The present invention is also directed to the combination of such a system with a passive needle guard that is automatically activated to extend a shield to cover a needle of the syringe and to methods of making and using such systems. Typically, a passive needle guard shield is activated when a radial portion or thumb pad of a plunger contacts a lateral catch or trigger finger of the passive needle guard. As the thumb pad of the plunger is moved distally, the trigger finger is forced laterally which results in a shield being forced distally to cover a needle of the syringe or in some designs, the syringe needle withdraws into the shield.
The present disclosure describes a needle guard device or system that can be used with drugs requiring reconstitution without activating the safety mechanism, yet provides needle safety shielding after the drug has been injected into the patient. In a preferred embodiment, the needle guard device would be assembled and sold with a syringe that is preferably pre-filled with the diluent. In a preferred embodiment, a clip is coupled to the needle guard during the reconstitution phase. The clip is configured to interact with the needle guard such that the shield is not activated to the extended position when the thumb pad of the plunger contacts the trigger fingers. Following reconstitution, the clip can be removed and the reconstituted medicine can be administered to the patient. During administration, the shield of the needle guard can be activated to extend and cover the needle.
