Wound drainage device
First Claim
1. A patient wound drainage device comprising manually operable wound suction pump means for connection with a catheter disposed adjacent a body wound of a patient for removing and collecting drainage liquid from the body wound, said pump means including a resilient, at least partially collapsible drainage receptacle, a pump inlet port connected to said receptacle means for connection said pump inlet port to a catheter so that said receptacle can receive drainage liquid from the body wound, and a pump outlet port connected to said receptacle for discharging drainage liquid therefrom, said receptacle being hand squeezable and releasable for producing a suction force at said pump inlet port, a one-way valve connected in series with said pump inlet port to prevent drainage liquid flow from said receptacle to the catheter, a fluid drainage storage bag including a pair of pliable sheet material members in face-to-face relation forming the sidewalls of the bag, a bag inlet port connected to the upper end portion of said bag, fluid connector means for connecting said pump outlet port with said bag inlet so that drainage liquid can be pumped from said receptacle into said bag by hand squeezing said receptacle, releasable connection means for connecting said receptacle to said bag in side-by-side relation with the sidewalls of said bag and receptacle in facing adjacent relation and with said receptacle between the upper and lower ends of said bag, and means for securing said bag, with said receptacle connected thereto, to the patient.

Abstract
A wound drainage device is provided which includes a manually operable suction pump having inlet and outlet ports, and a pliable fluid storage bag having a pair of plastic sheets in face-to-face contact and an inlet. The pump inlet port is adapted to be connected to a wound suction catheter for removing drainage fluid from the wound. The pump outlet port is connectable to storage bag inlet for discharging drainage fluid into the storage bag without disconnecting the suction catheter. The bag has an upper foldable portion between the main storage portion and the bag inlet to close fluid communication to the bag and can serve as an added protection against drainage fluid flowing back to the suction pump. The storage bag can be used to receive drainage fluid and thereby provide a relatively large storage capacity without requiring a relatively large suction pump.

- 1. A patient wound drainage device comprising manually operable wound suction pump means for connection with a catheter disposed adjacent a body wound of a patient for removing and collecting drainage liquid from the body wound, said pump means including a resilient, at least partially collapsible drainage receptacle, a pump inlet port connected to said receptacle means for connection said pump inlet port to a catheter so that said receptacle can receive drainage liquid from the body wound, and a pump outlet port connected to said receptacle for discharging drainage liquid therefrom, said receptacle being hand squeezable and releasable for producing a suction force at said pump inlet port, a one-way valve connected in series with said pump inlet port to prevent drainage liquid flow from said receptacle to the catheter, a fluid drainage storage bag including a pair of pliable sheet material members in face-to-face relation forming the sidewalls of the bag, a bag inlet port connected to the upper end portion of said bag, fluid connector means for connecting said pump outlet port with said bag inlet so that drainage liquid can be pumped from said receptacle into said bag by hand squeezing said receptacle, releasable connection means for connecting said receptacle to said bag in side-by-side relation with the sidewalls of said bag and receptacle in facing adjacent relation and with said receptacle between the upper and lower ends of said bag, and means for securing said bag, with said receptacle connected thereto, to the patient.
- 14. A patient wound drainage device comprising a hand squeezable wound suction pump including a resilient, at least partially collapsible receptacle means having an upper end portion, an inlet port connected to said upper end portion for connection with a suction catheter adapted to be placed in fluid communication with a body wound of a patient, said receptacle means being hand squeezable and releasable for producing a suction force for facilitating drainage liquid flow from the wound to said receptacle means, a one-way fluid valve connected in series with said inlet port and said receptacle means to prevent return drainage liquid flow from said receptacle means to the catheter, a drainage fluid outlet port connected to said receptacle means, a pliable drainage fluid storage bag including a pair of sheet members of pliable material in face-to-face relation with each other forming the sidewalls of the bag, said bag having a main storage portion and an upper neck portion having one end connected to said main storage portion, and a bag inlet port connected to the other end of said neck portion, and tube means connected between said bag inlet port and said receptacle means fluid outlet port, means for removably connecting said receptacle means to said bag with said neck portion folded back toward said main storage portion to close off fluid communication between said bag inlet port and said main storage portiion, said neck portion being substantially unfoldable to allow drainage liquid flow from said receptacle means through said tube means, said neck portion and to said bag when said said receptacle means is removed from said bag and moved to substantially unfold said neck portion and squeezed to cause drainage liquid to flow therefrom, and means for securing said bag with said receptacle means connected thereto to the patient.
