Hazardous fluid infuser
First Claim
1. An infuser for transferring a hazardous treatment fluid from a syringe to a medical application comprising:
- a spill containing housing having an interior sealed against fluid leaks, a first end and a second end;
a medical application connecting element provided on the first end of the housing, the connecting element providing a fluidic coupling between the housing and the medical application;
a syringe seat for positive seating of a syringe provided at the second end of the housing;
a syringe connecting element located on the syringe seat and having a septum and a needle guiding means, the syringe connecting element providing a fluid-tight coupling between a needle of the syringe and the interior of the housing; and
a fluid passage provided within the interior of the housing and extending from the syringe coupling element to the medical application connecting element.

Abstract
An infuser for transferring hazardous treatment fluids to and from a medical application includes a spill containing housing having a medical application connecting element and a syringe seat. The syringe seat of the infuser leads to a syringe connecting element that provides a fluid coupling between the syringe and a fluid passage leading to the medical application connecting element. The interior of the housing can be sealed against leaks, for example, by providing the housing in two portions with a gasket provided between the portions. A fluid tight coupling between the syringe and the interior of the housing may be created by integrally forming a septum with the gasket and coupling the syringe with the syringe connecting element through the septum. The infuser can also be provided with two syringe seats so that two different fluids can be transferred. In one embodiment, a second syringe connecting element is provided in fluid-tight communication with a second fluid passage. A method for transferring fluids to and from a medical application is also disclosed.
