Abstract
Disclosed is a device for the parenteral delivery of a medication, such as a drug. The device includes upper and lower housings in which the upper housing is configured to move relative to the lower housing as a result of application of an external force to permit the user of the device to control the rate at which the drug is administered.
Claims20
A method of injecting a medication from a medication delivery device of the type including an upper housing, a lower housing, a syringe supported by the lower housing and having a needle, and a needle guard supported by the lower housing, the method comprising the steps of:
- placing the medication delivery device against a skin surface so as to cause the needle guard to abut the skin surface, wherein the upper housing is releasably locked with respect to movement toward the needle;
- applying a force against the upper housing along an insertion direction, thereby causing the skin surface to force the needle guard to retract relative to the lower housing and thereby expose the needle so as to insert the needle through the skin surface, wherein the applying step causes the needle guard to unlock the upper housing with respect to movement toward the needle, thereby allowing movement of the upper housing toward the needle;
- and
- after the unlocking step, continuing to apply the force against the upper housing along the insertion direction, thereby causing the upper housing to move toward the needle, thereby driving a medication contained within the syringe out the needle.
A method of injecting a medication from a medication delivery device of the type including an upper housing, a lower housing, a syringe supported by the lower housing and having a needle, a needle guard supported by the lower housing, and a middle housing coupled between the upper housing and the lower housing, the method comprising the steps of:
- placing the medication delivery device against a skin surface so as to cause the needle guard to abut the skin surface, wherein the upper housing is releasably locked with respect to movement toward the needle;
- applying a force against the upper housing along an insertion direction, thereby causing the skin surface to force the needle guard to retract relative to the lower housing and thereby expose the needle so as to insert the needle through the skin surface;
- during the applying step, unlocking the upper housing with respect to movement toward the needle, thereby allowing movement of the upper housing toward the needle;
- and
- after the unlocking step, continuing to apply the force against the upper housing along the insertion direction, thereby causing the upper housing to move toward the needle, thereby driving a medication contained within the syringe out the needle.
A method of injecting a medication from a medication delivery device of the type including an upper housing, a lower housing, a middle housing that includes a body that is exposed between the upper housing and the lower housing, and a syringe supported by the lower housing and having a needle, the method comprising the steps of:
- placing the medication delivery device against a skin surface;
- moving the medication delivery device toward the skin surface along a direction to thereby cause the needle to penetrate the skin surface;
- and
- applying a force to the upper housing along the direction to thereby move the upper housing along the middle housing body toward the needle such that the upper housing progressively covers the middle housing body as the upper housing moves toward the needle to thereby provide a visual indication that medication contained in the syringe is being delivered.
