SYRINGE HAVING MULTIPLE LUMENS

摘要

A syringe can be used to receive fluid from a patient. The syringe can include a syringe body, a first lumen disposed within an internal space of the syringe body, a second lumen disposed within the internal space of the syringe body, and a plunger slideably received along an internal surface of the second lumen. The syringe can also include a stem elongate along a first direction, a handle coupled to the stem, and a needle coupled to the syringe body. The syringe can be configured such that the plunger is moved through the second lumen along a first direction and the fluid is received into the first lumen along a second direction that is opposite the first direction.

主权项

1. A syringe comprising:
a syringe body elongate along a first direction, wherein the syringe body defines a proximal portion, a distal portion that is opposite the proximal portion, a sidewall that extends between the proximal and distal portions, and an internal space; a first lumen disposed within the internal space of the syringe body; a second lumen disposed within the internal space of the syringe body; a plunger slideably received along an internal surface of the second lumen, wherein the plunger defines a proximal surface and a distal surface that is opposite the proximal surface, and wherein the plunger is configured to move along a first direction and a second direction that is opposite the first direction; a stem elongate along the first direction, wherein the stem has a proximal end and a distal end that is opposite the proximal end, and wherein the distal end of the stem is coupled to the proximal end of the plunger, wherein the stem is configured to move along the first direction and the second direction; a handle coupled to the proximal end of the stem, wherein the handle is configured to move along the first direction and the second direction, wherein the handle and plunger are configured to move from a first position to a second position, wherein when the handle and plunger are in the first position, the syringe defines a first length, wherein when the handle and plunger are in the second position, the syringe defines a second length, and wherein the second length is greater than the first length; and a needle coupled to the distal portion of the syringe body, wherein the needle is configured to receive fluid through a tip of the needle, and wherein the fluid moves from the needle into the first lumen.
