Surgical drain system and method of use

A wearable surgical drain system for collection of fluid from a body of a user, the drain system comprising:

• a collection reservoir having a reservoir wall that defines an interior chamber and a collection port defined in a portion of the reservoir wall, wherein a drain port is defined in a portion of the reservoir wall, and wherein the drain port is configured to allow fluid collected in the interior chamber of the collection reservoir to be released;
• a collection tube having a distal end configured to be coupled to or in fluid communication to the user and a proximal end coupled to the collection port such that the distal end and an inner lumen of the collection tube, the collection port and the interior chamber of the collection reservoir;
• are in sealed fluid communication,
• a pump mechanism configured to charge the interior chamber of the collection reservoir with a vacuum pressure such that, when charged, the vacuum pressure urges fluid from the user through the inner lumen of the connection tube, through the collection port and into the interior chamber of the collection reservoir wherein, an air intake aperture is defined in a portion of the reservoir wall of the collection reservoir, and wherein the air intake aperture is configured to place the interior chamber of the collection reservoir in fluid communication with the outside atmosphere, wherein the collection port comprises a first one-way valve configured to prevent fluid from traveling out of the interior chamber of the collection reservoir through the collection port and a second one-way valve configured to allow gas to be removed from the interior chamber of the collection reservoir while preventing gas from undesirably entering the interior chamber of the collection reservoir;
• wherein the collection reservoir comprises a drain mechanism configured to simultaneously allow air to enter and fluid to exit the interior chamber of the collection reservoir, wherein the drain mechanism comprises a knob and a plunger, wherein the plunger has a distal end on which the knob is positioned, a proximal end of the plunger is configured to seal the drain port and a central portion extending between the proximal end and the distal end of the plunger wherein a plurality of channels are defined in a portion of the drain mechanism plunger which extends fully along a length of the central portion to the distal end of the drain mechanism plunger, and wherein the plurality of channels provide a path for fluid to enter the plunger from the interior chamber of the collection reservoir and to exit the drain port;
• and a belt configured to be worn by the user, wherein the wearable surgical drain system including the collection reservoir, the collection tube, the pump mechanism and drain mechanism are attachable to the belt so that the wearable surgical drain system is configured to be wearable by the user without clothing while dressing or showering and worn under clothing without being detectable.
