A bulb evacuator is provided for closed wound suction having a flexible compressible container with a pair of inlets having one way valves therein and a port to a suction source with a removable cap thereon at one end of the bulb evacuator. The opposite end of the bulb evacuator is provided with an integrally formed anti-reflux valve and a latching device surrounding the anti-reflux valve. A separate collection bag can be attached to the latching device so that when the bulb evacuator is filled with fluid from a closed wound, it can be compressed to force the fluid into the attached collection chamber and simultaneously creating a suction within the bulb evacuator to promote further withdrawal of fluids from the closed wound.

Bulb evacuator for closed wound suction

A compact, lightweight, variable rate suction and collection device is provided for the withdrawal and collection of fluid from a patient. The device includes a collection receptacle which is connected to the patient and to a pump through suction inlet, so that suction is created within the collection receptacle whereby fluids from the patient are drawn into the receptacle. A piezoelectric transducer or diaphragm pressure switch senses the suction created while a suction level selector permits an operator to select a given suction pressure within a predetermined range. A control circuit, responsive to the piezoelectric transducer or switch and to the suction level selector, controls the suction created within the receptacle. Among other features, the control circuit provides a selected suction pressure as well as controls delivery of fractional power to the pump motor to reduce noise. The entire unit including the pump and collection receptacle may be located within a carrying case so that the unit can be worn by a patient or hung at a patient's bedside.

Wearable, variable rate suction/collection device

A closed system method and apparatus for removing collected liquid from a portable closed wound suction drainage device which reduces the potential contamination of the drainage device and cross infection from the use of the drainage device is disclosed. A disposable collection bag is attached to the outlet (emptying port) of the drainage device and the contents are transferred in a closed system procedure into this collection bag through a one-way inlet. After transferring the contents, the filled collection bag is removed from the outlet and capped for subsequent disposal, and a new collection bag is attached to the outlet of the drainage device. Preferably, the collection bag is compacted, such as by rolling, and held in this compact form by a retainer. A protective closure cap is provided for the inlet of the collection bag to form a cover and seal for the inlet both before fitment to the device and after filling. The cap also prevents leakage or the escape of contamination from the disposable collection bag after filling. A special skirt is provided with the bag inlet connector to prevent contamination of the inlet during the attachment procedure and to form a protective seal and cover over the exterior of the drainage device outlet to prevent contamination of the outlet while the device is collecting the drainage. The skirt also combines with the tapered inlet to provide a secure and leakfree fitment between collection bag and drainage device.
