Surgical drain system and method of use
A surgical drain system for use during and following surgery is provided. A collection reservoir is placed in fluid communication with the body of a user through a collection port. A pump creates a vacuum pressure to urge fluid into the collection reservoir. Fluid exits the collection reservoir through a drain port. A drain mechanism allows air to come into the collection reservoir through an air intake aperture and collected fluid to leave the reservoir simultaneously. The drain system can be worn beneath clothes.
1. 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.
2. The drain system of claim 1 , wherein a pump port is defined in a portion of the reservoir wall of the collection reservoir.
3. The drain system of claim 2 , further comprising a pump connector having a distal end coupled to the pump mechanism and a proximal end coupled to the pump port of the collection reservoir such that at least a portion of the vacuum pressure created by the pump mechanism is transmitted through an inner lumen of the pump connector and into the interior chamber of the collection reservoir.
4. The drain system of claim 1 , further comprising a drain tube coupled to the drain port, wherein the drain tube is configured to direct fluid exiting the interior chamber of the collection reservoir through the drain port out of the drain system.
5. The drain system of claim 1 , wherein at least a portion of the knob is positioned outside of the interior chamber of the collection reservoir and is configured to selectively seal the air intake.
6. The drain system of claim 5 , wherein at least a portion of the central portion of the plunger extends through the interior chamber of the collection reservoir.
7. The drain system of claim 6 , wherein the plunger is selectively movable about and between a first, sealed position, in which the air intake aperture is sealed by the knob and the drain port is sealed by the proximal end of the plunger and a second, open position, in which, the knob is spaced from the air intake aperture a first predetermined distance and the proximal end of the plunger is spaced from the drain port a second predetermined distance that equals the first predetermined distance.
8. The drain system of claim 6 , wherein the plunger is selectively movable about and between a first, sealed position, in which the air intake aperture is sealed by the knob and the drain port is sealed by the proximal end of the plunger and a second, open position, in which, the air intake aperture is not sealed by the knob and the drain port is not sealed by the proximal end of the plunger.
9. The drain system of claim 8 , wherein the drain mechanism further comprises a biasing element configured to urge the plunger to the first, sealed position.
