This invention relates to surgical appliances for vacuum actuated testing devices for use in hospitals, laboratories and the like, and in particular a foot actuated vacuum pump in combination with a precipitator and suitable vacuum connections from the precipitator to apply vacuum or suction to different devices for different uses.

The purpose of this invention is to provide means for obtaining vacuum without the use oi mechanical power whereby vacuum may be used in a hospital or laboratory for transferring iiuids from one container to another without subjecting the products to air, for measuring poisonous liquids, for ltering solutions or" biological products, for absorbing liquids from the lungs and other parts of the body and also for drying bleeds, such as on cuts or injuries, andA also for drying pipettes and the like.

Vacuum is not used in numerous instances in hospitals, laboratories, and the like because it is diilicult to sterilize conventional pumping equipment such as is required for obtaining vacuum and also as vacuum equipment of this type is comparatively costly. In numerous instances the use of vacuum would save time and reduce the possibility of infections. With this thought in mind this invention contemplates a comparatively small foot actuated vacuum pump positioned in a portable stand and connected to a precipitator from which nozzles or connecting tubes extend.

The object of this invention is, therefore, to provide means for forming a portable Vacuum machine or applicator with which vacuum may be provided at different points in a hospital, laboratory or the like, and where use thereof is desired.

Another object of the invention is to provide a. vacuum applicator that is adapted for universal use in a hospital, laboratory, or the like.

A further object of the invention is to provide a vacuum machine that is mounted in combination with a precipitator on a portable stand and in which the device is provided with a suction nozzle which provides a portable vacuum applicator of a simple and economical construction.

With these yand other objects and advantages in View the invention embodies a vacuum cylinder suspended by a link in a portable housing and having a piston in the cylinder attached to a foot lever, and a precipitator mounted in or on the housing and connected to the cylinder and also having a nozzle extended therefrom.
