Abstract

A surgical drape for use in a thermal treatment system congealing a sterile medium within a basin and automatically dislodging the congealed sterile medium adhered to the drape adjacent basin walls is accomplished by a drape having a drape portion covering the system housing with part of the drape portion disposed in the basin. The drape may further include a pre-formed container portion fitted to match the contour of, and being disposed within, the basin. The container portion may accommodate various shaped basins and include individual fluted sections, drape deformities, or an inflatable bladder surrounded by the fluted sections for facilitating dislodgement of the congealed medium. Further, the drape or preformed container portion may include a substantially annular bladder, or a bladder having a plurality of individually inflatable sections for manipulation of the drape relative to the basin to dislodge the congealed sterile medium. Alternatively, the bladders may be disposed between the drape or container portion and bottom of the basin for manipulation of the drape as described above. Moreover, the drapes may include stirrups to secure the drape to the system. A pump or bellows inflates and deflates the bladders via a piston having a reciprocating motion within a chamber, or, alternatively, via separate connections for inflation and deflation which are controlled by selective actuation of solenoids. The individually inflatable sections are inflated and deflated one section at a time in sequential order to manipulate the drape relative to the basin to dislodge the congealed sterile medium.

Claims

1. An apparatus for thermally treating a sterile medium comprising:

a system housing including a top surface;

a basin recessed in said top surface of said housing for transferring thermal energy to said sterile medium;

a drape covering and hanging down from said top surface of said housing with a portion of said drape disposed in said basin for collecting said sterile medium;

thermal treatment means in thermal relation with said basin for thermally treating said sterile medium such that said sterile medium congeals and adheres to said drape adjacent walls of said basin;

manipulation means disposed in said basin for automatically manipulating said drape wherein said manipulation means includes a plurality of individually inflatable sections; and

pump means for inflating and deflating said individually inflatable sections in sequential order to manipulate said drape relative to said basin and dislodge said congealed sterile medium from said drape.

2. The apparatus of claim 1 further including:

a plurality of basins recessed in said top surface of said housing for containing said sterile medium, wherein said thermal treatment means thermally treats a portion of said basins to congeal said sterile medium; and

a plurality of said manipulation means wherein each said manipulation means is disposed in one of said basins thermally treated to congeal said sterile medium;

wherein said pump means inflates and deflates said plurality of manipulation means to manipulate said drape and dislodge congealed sterile medium in said basins congealing said sterile medium.

3. The apparatus of claim 1 wherein said pump means further includes:

a chamber;

connection means for connecting each of said individually inflatable sections to said chamber;

a piston disposed within said chamber; and

drive means for driving said piston within said chamber in a reciprocating manner such that said reciprocating motion of the piston within the chamber alternately inflates and deflates each said individually inflatable section of said manipulation means one section at a time in sequential order.

4. The apparatus of claim 1 further including:

pump connection means for connecting each of said individually inflatable sections to said pump means via a first and second path, said first path establishing a connection for inflating said individually inflatable sections and said second path for establishing a connection to deflate said individually inflatable sections;

solenoid means disposed within said pump connection means for controlling said inflation and deflation of said individually inflatable sections; and

solenoid control means for selectively actuating said solenoid means to inflate and deflate said individually inflatable sections one section at a time in sequential order.

5. In the apparatus of claim 1, a method of dislodging congealed sterile medium adhering to said drape adjacent walls of said basin comprising the step of:

(a) inflating and deflating said individually inflatable sections in sequential order one section at a time via said pump means to manipulate said drape relative to said basin and dislodge said congealed sterile medium adhering to said drape adjacent walls of said basin.

6. The method of claim 5 wherein said apparatus further includes:

a plurality of basins recessed in said top surface of said housing for containing said sterile medium wherein said thermal treatment means thermally treats a portion of said basins to congeal said sterile medium;

a plurality of said manipulation means wherein each of said manipulation means is disposed within said basins thermally treated to congeal said sterile medium, and step (a) further includes;

(a.1) inflating and deflating each of said manipulation means to manipulate said drape relative to said basins congealing said sterile medium to dislodge said congealed sterile medium.

7. The method of claim 5 wherein said pump means is connected to said individually inflatable sections and includes a piston disposed within a chamber for inflating and deflating said individually inflatable sections, and step (a) further includes:
