Abstract

A syringe body is disclosed, wherein the syringe body is configured to withstand pressures within a fluid reservoir of the syringe body of between about 0 atmospheres (atm) and about 81 atm and/or between about 0 atm and about 109 atm. The syringe body may be configured for use in connection with an inflation device. The syringe body may comprise one or more stiffening ribs and/or a stiffening lip. Methods of using the syringe body in connection with an inflation device are also disclosed.

First claim

The invention claimed is:

1. A syringe body configured for use in connection with a high-pressure inflation device, the syringe body comprising:
a first wall defining a fluid reservoir, the fluid reservoir configured to receive a plunger;
a second wall defining a distal end of the fluid reservoir, the second wall comprising:
at least one stiffening rib; and

an inlet/outlet port disposed in the second wall,
wherein a distal end of the first wall extends distally relative to the second wall along a circumference of the second wall forming an annular stiffening lip,
wherein the second wall defines an interior surface of the fluid reservoir extending between the first wall and the inlet/outlet port, and
wherein the at least one stiffening rib extends inward of the annular stiffening lip along an exterior surface of the second wall.

2. The syringe body of claim 1 , wherein the fluid reservoir is further defined by a space at least partially enclosed by the first wall and disposed between a plunger seal and the second wall.

3. The syringe body of claim 1 , wherein the second wall is substantially circular.

4. The syringe body of claim 1 , wherein a height of a first portion of the annular stiffening lip is greater than a height of a second portion of the annular stiffening lip.

5. The syringe body of claim 1 , wherein the second wall comprises a plurality of stiffening ribs and wherein a shape of a first plurality of stiffening ribs is substantially triangular when viewed from a distal end of the syringe body.

6. The syringe body of claim 5 , wherein a shape of a second plurality of stiffening ribs is substantially trapezoidal when viewed from the distal end of the syringe body.

7. The syringe body of claim 1 , wherein the second wall comprises a plurality of stiffening ribs and wherein the plurality of stiffening ribs forms a substantially diamond shape when viewed from a distal end of the syringe body.

8. The syringe body of claim 1 , wherein a first stiffening rib defines a first chord along the exterior surface of the second wall.

9. The syringe body of claim 8 , wherein a second stiffening rib defines a second chord along the exterior surface of the second wall.

10. The syringe body of claim 9 , wherein a third stiffening rib defines a third chord along the exterior surface of the second wall.

11. The syringe body of claim 1 , wherein the syringe body is configured to withstand a pressure of up to at least about 81 atmospheres (atm) within the fluid reservoir.

12. The syringe body of claim 11 , wherein the syringe body is configured to withstand a pressure of up to at least about 109 atm within the fluid reservoir.

13. The syringe body of claim 1 , wherein a height of a first portion of the at least one stiffening rib is greater than a height of a second portion of the at least one stiffening rib.

14. The syringe body of claim 13 , wherein the second portion of the at least one stiffening rib is disposed radially inward, with respect to the syringe body, of the first portion of the at least one stiffening rib.

15. The syringe body of claim 1 , wherein the second wall comprises a plurality of stiffening ribs disposed along the exterior surface of the second wall, the plurality of stiffening ribs extending radially outward from the inlet/outlet port to the annular stiffening lip.
