Syringe adapter

Abstract

The present invention includes syringes for dispensing liquids. The devices of the invention increase ease of volume control and hence application thereof while minimizing any spilage or fluid migration up the side of the syringe tip.

Description

technical field [0001] The present invention relates to syringes for dispensing liquids. In particular, a syringe with an adapter is provided that can be used to dispense very small volumes of liquid. Background technique [0002] In many medical and laboratory applications it is necessary to provide or administer single or precisely measured doses of liquid agents such as blood, medicaments or reagents. One such application requiring precise fluid dosing is in systems used by patients to measure bodily analytes in physiological fluids. Such systems typically include a test strip containing reagent material to which a physiological sample is applied. Meters are configured to receive such test strips and determine the analyte concentration in the sample. Before such meters and test strips are used, they are typically checked by various methods in which a monitor agent, often called a control fluid, is used to test the accuracy and efficacy of the test strips.

Problems solved by technology

However, such syringes lack accuracy in dispensing the much smaller volumes required by today's more advanced test strips, which require volumes of less than 1 microliter

[0004] Since some commercially available test strips require sub-microliter sample volumes, existing syringes may deliver excessively large volumes of control solution, causing inconvenience and annoyance to the user

For example, when holding a syringe and pushing the plunger at the same time, it can be difficult to precisely aim a large droplet onto the reaction area on the test strip
