Abstract
A valve arrangement for providing clinical nutrition is provided. The valve arrangement is suitable for use with a rotary peristaltic pump and is capable of allowing flow of fluid in a first direction and capable of preventing flow of fluid in a second direction, wherein the valve arrangement comprises a valve having a cracking pressure of about 0.10 to about 0.20 bar. Also described are a method of production of the valve arrangement, use of the valve arrangement in providing nutrition to a patient and a method of treatment of a patient that comprises administering an effective amount of a composition via the valve arrangement.

A valve arrangement suitable for use with a rotary peristaltic pump and which is capable of allowing a flow of fluid in a first direction and capable of preventing the flow of fluid in a second direction, wherein the valve arrangement comprises a valve having a cracking pressure of approximately 0.10 to about 0.20 bar.
A device for the administration of at least one fluid to a patient comprising:
- a valve arrangement including a member that is deformable under pressure in a desired flow direction and having a cracking pressure of approximately 0.10 to about 0.20 bar;
- an inlet tube for providing, at least in part, a fluid flow path between a container and an inlet port of the valve arrangement;
- and
- an outlet tube for providing, at least in part, a fluid flow path between an outlet of the valve arrangement and a patient.
A method for manufacturing a valve arrangement for use in a medical device for delivering a fluid to a patient comprising the steps of producing a chamber having an inlet port and an outlet port, locating within the chamber a one way valve between the inlet port and the outlet port for allowing fluid to flow in only one direction, and having a cracking pressure of approximately 0.10 to about 0.20 bar.
A method of providing a fluid to a patient comprising the steps of administering an effective amount of a fluid via a valve arrangement having a cracking pressure of approximately 0.10 to about 0.20 bar.
A method of treating a patient comprising the steps of administering a fluid from a container to a patient using a pump to propel the fluid via a valve arrangement having a cracking pressure of approximately 0.10 to about 0.20 bar.
A device for controlling the flow of a fluid from a container to a patient including a valve arrangement that is so constructed and arranged to prevent the flow of fluid to a patient at certain conditions, allow the flow of fluid to a patient at a cracking pressure, and allow a certain level of a free flow of fluid to the patient.
