METHOD AND SYSTEM FOR REMOVING EXUDATES FROM A WOUND SITE
First Claim
1. An apparatus for controlling flow of fluid from a wound site of a patient comprising:
- a chamber connectable in fluid communication with the wound site and a reservoir for receiving and holding fluid, the chamber having a first state and a second state, the chamber in the first state being deformed and in the second state being non-deformed or less deformed than in the first state, wherein the chamber is adapted to manage fluid flow between the wound site and the reservoir during transition of the chamber between the first state and the second state; and
an actuator element adapted to operate on the chamber to transition the chamber from the second state to the first state.

Abstract
An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.

13. An apparatus for controlling flow of fluid from a wound site of a patient comprising:
-
a passive pump unit including a chamber having an input for receiving the fluid from the wound site of the patient conveyed over a conduit connectable in fluid communication with the input and an output for providing the received fluid from the chamber; and an actuator element operable to create a pressure within the chamber for drawing the fluid from the wound site through the conduit and the input and into the chamber, wherein the chamber is adapted to hold the received fluid without the received fluid flowing through the input and the output and to provide the received fluid from the chamber through the output without the received fluid flowing through the input. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
