摘要： An inflation system for pressurization and depressurization of a balloon catheter. The inflation system includes a syringe, including a syringe barrel, a plunger with expandable thread, a handle with cam, a syringe end cap, pressure gauge, flexible tubing, and connectors. The syringe is structured such that part of the syringe barrel has an internal thread which engages the expandable threads of the plunger. In the disengaged mode, the plunger slides freely within the syringe barrel allowing for rapid motion to purge, pressurize, or depressurize the inflation system. Once pressure reaches a predetermined level in the system, the cam on the handle causes the threads to automatically lock against the syringe barrel, and continued pressurization or depressurization is accomplished by the rotation of the plunger handle with respect to the syringe barrel. One advantage of the inflation system is that only one step is necessary for locking the syringe for controlled pressurization and depressurization.

摘要： An inflation system for pressurization and depressurization of a balloon catheter. The inflation system includes a syringe, including a syringe barrel, a plunger with expandable thread, a handle with cam, a syringe end cap, and a digital pressure gauge. The syringe is structured such that part of the syringe barrel has an internal thread which engages the expandable threads of the plunger. In the disengaged mode, the plunger slides freely within the syringe barrel allowing for rapid motion to purge, pressurize, or depressurize the inflation system. Once pressure reaches a predetermined level in the system, the cam on the handle causes the threads to automatically lock against the syringe barrel, and continued pressurization or depressurization is accomplished by the rotation of the plunger handle with respect to the syringe barrel. One advantage of the inflation system is that only one step is necessary for locking the syringe for controlled pressurization and depressurization. A digital display engages to a pressure port to indicate the pressure and displays absolute pressure and elapsed time at absolute pressure. In addition, the digital display provides for a communication interface to a data acquisition system such as a personal computer to record date, time and pressure over finite term periods.

摘要： 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.

摘要： 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.
