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.
Claims37
A device for administering medication, the device comprising:
- a lower housing having a bottom surface and supporting a syringe that is configured to contain a medication therein;
- a middle housing attached to the lower housing and comprising a body;
- an upper housing attached to the middle housing and configured to move along the middle housing toward the bottom surface of the lower housing from a first position to a second position, wherein the middle housing body is exposed between the upper housing and the lower housing when the upper housing is in the first position, and the upper housing substantially completely covers the middle housing body when the upper housing is in the second position;
- and
- a plunger rod supported by the upper housing, wherein movement of the upper housing from the first position to the second position causes the plunger rod to advance with the upper housing relative to the syringe, thereby causing the syringe to deliver the medication.

A device for administering medication, the device comprising:
- a lower housing and a syringe supported by the lower housing, the syringe having a needle attached thereto and medication disposed therein;
- a plunger rod;
- an upper housing moveably supported by the lower housing and configured to move toward the lower housing to cause the plunger rod to advance into the syringe and eject the medication out the needle;
- and
- a biasing element configured to produce a biasing force that biases the upper housing to move toward the lower housing, but is insufficient to cause the upper housing to move toward the lower housing, the biasing force configured to assist an external force that is applied to the upper housing in a direction toward the lower housing so as to cause the upper housing to move toward the lower housing.

A device for administering medication, the device comprising:
- a lower housing having a bottom surface and supporting a syringe that is configured to contain a medication therein, the lower housing comprising a needle guard, wherein the needle guard moves upwardly to expose a needle when the lower housing bottom surface is pressed against a skin surface;
- a middle housing attached to the lower housing and comprising a body;
- an upper housing attached to the middle housing and configured to move along the middle housing toward the bottom surface of the lower housing from a first position to a second position, wherein the middle housing body is exposed between the upper housing and the lower housing when the upper housing is in the first position, and the upper housing substantially completely covers the middle housing body when the upper housing is in the second position;
- and
- a plunger rod supported by the upper housing, wherein movement of the upper housing from the first position to the second position causes the plunger rod to advance relative to the syringe, thereby causing the syringe to deliver the medication.

- and
- a plunger rod supported by the upper housing, wherein movement of the upper housing from the first position to the second position causes the plunger rod to advance relative to the syringe, thereby causing the syringe to deliver the medication;
- and
- an assist drive capable of applying a downward force on the upper housing.

A device for administering medication, the device comprising:
- a lower housing having a bottom surface and supporting a syringe that is configured to contain a medication therein;
- a middle housing attached to the lower housing and comprising a body;
- an upper housing attached to the middle housing and configured to move along the middle housing toward the bottom surface of the lower housing from a first position to a second position, wherein the middle housing body is exposed between the upper housing and the lower housing when the upper housing is in the first position, and the upper housing substantially completely covers the middle housing body when the upper housing is in the second position;
- and
- a plunger rod supported by the upper housing, wherein:
- movement of the upper housing from the first position to the second position causes the plunger rod to advance relative to the syringe, thereby causing the syringe to deliver the medication;
- and
- the plunger rod bears against the medication contained within the syringe as the upper housing is moved toward the second position to thereby cause the syringe to deliver the medication.
