Automatic surgical sponge counter and blood loss determination system
First Claim
1. A sponge bucket apparatus for receiving and automatically counting used surgical sponges of different size and shapes, each sponge having an indicating means thereon for identifying the sponge, the apparatus comprising:
- a) a bucket container body having an interior for containing used surgical sponges, the container having an upper end with a single opening through which used surgical sponges enter the container, a lower end with a base and a side wall;
b) a non-optical scanner positioned next to the opening for detecting a surgical sponge entering the container through the opening;
c) a display on the container body for displaying the number of sponges which have entered the container through the opening since a predetermined time;
d) wherein the scanner automatically determines the type of sponge which enters the container body through the opening, even if sponges of different sizes and shapes pass through the opening in sequence; and
e) the first display having indicia that indicates the number of each different type of sponge which has entered the container body through the single opening in a predetermined time frame.

Abstract
A surgical sponge detection system includes a plurality of surgical sponges (2) having radio frequency identification tags (1) securely attached thereto and a non-optical hand-held reader (40) for detecting the sponges by detecting the tags (1). Also disclosed is a device (30) for automatically counting, weighing, and calculating blood loss contained within, soiled surgical sponges (2) which includes a cabinet with an opening (3) at the top through which sponges (2) are deposited, a reader (6) which scans each sponge (2) entered and determines sponge type from a tag (1) affixed to each sponge (2), and a disposable bag (8) into which the sponges (2) are deposited. The disposable bag (8) is removably mounted to a weighing scale (10); there is also a rear door (9) from which the disposable bag (8) can be easily removed, a rechargeable battery (11), a shelf (12) for unused disposable bag storage, a control unit (4) which processes data received from reader (6) and scale (10) and instantaneously calculates total weight of liquid contained within sponges entered, a display panel (5) continuously displays the number and type of sponges entered during a given procedure as well as the total weight of liquids retained in those sponges. There is a means for automatically determining the weight of the sponges when dry which includes a non-optical scanner means (6) which can read an indicating means (1) on the sponges (2) even when the indicating means (1) is covered with blood or other body fluids.

6. A surgical sponge bucket, comprising:
-
a) a bucket container having an interior; b) a plurality of sponges of varying weights, each sponge having an indicator thereon for identifying the sponge; c) a device for counting the surgical sponges, that includes a single opening in the upper end portion of the container for receiving the surgical sponges; d) a scanner that detects when one of the surgical sponges passes through the opening; e) a counter that counts the number of surgical sponges that have entered the container in a predetermined time frame; and f) a display that displays the number of surgical sponges that have entered the container in a predetermined time frame; g) wherein different types of surgical sponges are received by the container; and h) wherein the scanner is capable of distinguishing between multiple types of surgical sponges that pass through the single opening, even those sponges are of different types but similar weights, and the display means displays the number of each type of sponge which is received. - View Dependent Claims (7, 8, 9, 11, 13)
