Abstract

The syringe systems disclosed herein provide in part devices for allowing patients with compromised joint strength to more easily administer medicine. Certain exemplary syringe embodiments include a handle forming a handgrip, a syringe barrel that magnifies the dosage marks located on an inner barrel, and a tip cap slidably engageable with the syringe barrel for shielding a needle.

Claims

1. A tip cap slidably engageable with a distal end of a syringe barrel for shielding the needle comprising:

an outer cap;

an inner cap; and

a connector shaped to fit within and engage the outer cap and engage the inner cap and having a plurality of first legs spaced symmetrically away from one another, each first leg having a plurality of internally facing barbs pointing toward a distal region of the connector and adapted to engage a proximal region of the inner cap, wherein each of the plurality of internally facing barbs is disposed at an angle with respect to the plurality of first legs, the connector having a plurality of second legs spaced symmetrically away from one another, each second leg having a plurality of externally facing barb tips located at an end of a respective second leg and adapted to engage a distal region of the outer cap,

wherein the outer cap includes a shoulder having an inner surface, an outer surface, and a mating protrusion formed on the inner surface and shaped to matingly engage with a recess of the syringe barrel,

wherein the outer cap further includes a stem having a stem orifice and a hollow inner space shaped to receive the connector,

wherein the shoulder flares outwardly and away from the stem to define an outer cap orifice that is wider than the stem orifice,

wherein the mating protrusion does not extend radially inwards as far as the stem orifice,

wherein the mating protrusion includes a top surface and a side surface,

wherein the top surface and the side surface of the mating protrusion are perpendicular to each other, and

wherein the outer cap has a center axis and is symmetrical about the center axis.

2. The tip cap according to claim 1, wherein the outer cap includes a gripping ring.

3. The tip cap according to claim 1, comprising a plurality of the mating protrusions.

4. The tip cap according to claim 3, comprising a pair of the mating protrusions disposed opposite to each other.

5. The tip cap according to claim 1, wherein the top surface of the mating protrusion is perpendicular to the center axis of the outer cap.
