Abstract
A portable liquid collection device is disclosed which is used for draining the pleural cavity or the like. An electric pump and battery means are located inside of a housing. Also located inside of the housing are an adjustable valve and a manually operated emergency pump. A detachable liquid collection chamber is held to the housing by a handle and a latch on the handle. Extending from the pump to the collection chamber through the handle is a vacuum line. When a hose from the pleural cavity is connected to the collection chamber, the electric pump is turned on by a switch and creates a vacuum in the chamber which draws liquids through the hose. If liquid in the chamber rises too high, a float valve in the chamber prevents any liquid from being drawn into the vacuum line.
Claims9
A portable fluid collection device comprising a housing including an outwardly extending base portion to receive a collection chamber,
- pump means in said housing,
- a vacuum line connected to said pump means,
- a hollow integrally mounted handle on said housing, said handle having a free end extending from said housing above the base portion, said vacuum line extending through said handle,
- a collection chamber separate and detachable from said base portion of the housing,
- a groove formed in said collection chamber to receive the free end of said handle when said collection chamber is attached to said housing,
- an opening in said collection chamber adapted to be in alignment with said vacuum line when the collection chamber is received on the handle of said housing,
- latch means for latching the collection chamber to the handle and to secure said housing and collection chamber together,
- means for collecting said collection chamber with a body cavity of a patient whereby when said device is operative, said pump means maintains a lowered pressure in the collection chamber and in the body cavity of the patient and the collection chamber receives fluid from the body cavity and when the collection chamber is filled, the collection chamber may be removed from the housing.
A portable fluid collection device comprising:
- a housing;
- a battery located in said housing;
- a vacuum producing electric pump electrically connected to said battery and located in said housing;
- a handle protruding from said housing and located above a portion of said housing;
- latch means including a stop on said handle;
- a vacuum line extending from said electric pump, through said handle, and having a portion which terminates beyond said stop of said handle;
- an adjustable bleed valve fluidly connected to said vacuum line and located in said housing;
- a manually operated emergency pump which is fluidly connected to said bleed valve;
- a detachable liquid collection chamber;
- means for connecting said chamber with a hose leading to the area to be drained;
- a vacuum line opening in said chamber which receives the portion of said vacuum line extending beyond said stop of said handle;
- a valve means located between said means for connecting a hose and said vacuum opening for preventing the withdrawal of any liquid through said vacuum line;
- and
- a recessed slot in said collection chamber for receiving said reduced end portion of said handle;
- such that said chamber is held between said handle and said housing by said latch means and as said chamber slides onto said housing and said handle, said handle acts as a guide in said recessed slot of said chamber so that said vacuum line opening receives the portion of said vacuum line extending beyond said stop.
