A unitary portable power suction system for dental use comprises a housing, a power supply mounted in the housing and a vacuum pump for creating a suction flow of preferably 1250 l/min, and creates a pressure of preferably 150 mbar. The vacuum pump has a vacuum pump inlet and a vacuum pump outlet and is mounted in the housing and connected to and powered by the power supply. The unitary power suction system also comprises a cyclone separator for separating fluids from the suction flow and has a cyclone separator inlet and a cyclone separator outlet. The cyclone separator inlet constitutes a system air inlet and the cyclone separator outlet is in fluid communication with the vacuum pump inlet. The unitary power suction system further comprises a filter means for removing particles. The filter means is mounted in the housing and has a filter outlet and a filter inlet. The filter inlet is in fluid communication with the vacuum pump outlet for receiving the suction flow, and the filter outlet constitutes a system air outlet. The filter means and the cycle separator create a pressure loss such that the pressure at the system air inlet does not exceed 50-70 mbar, and the air flow at the system air inlet is at least 200-400 l/min. |

| 27 | Surgical drill apparatus | US387247 | 1982-06-10 | US4464113A | 1984-08-07 | Richard J. Parmley |
| Surgical drill apparatus includes a stand with a base and an upright column, a sterilizable water tank manually mountable on and demountable from the column, a gas flow control valve, equipped with a pedal, mounted on the base, oxygen lines connected to the valve, hence to the tank, thence to a surgical drill, and a water line connected to the water tank and the surgical drill. An oxygen line connected to one side of the valve at one end is connected to the hospital oxygen supply at its other end. The oxygen and water lines are plastic and equipped with quick-disconnect fittings complementary to fittings on the water tank. The water tank is of a size to hold sufficient water to permit the completion of any operation in which the drill is likely to be used. A simple, repeatedly sterilizable or disposable pinch valve is used to control the flow of water to the drill. | ||||||

| A predictive maintenance system and method for a dental handpiece includes a condition sensor for sensing a condition of the handpiece to obtain sensor data and providing wired communication of the sensor data and a device identifier from the handpiece to a delivery unit. The system is configured to store sensor data, a device identifier and a time stamp in data logging equipment to obtain a usage history for the handpiece. The system determines a maintenance condition of the handpiece based on the sensor data and/or the usage history of the handpiece. In response to a severity of the maintenance condition, the system provides a preventative maintenance indication of a future failure for the handpiece or stops operation of the handpiece. | ||||||
