Abstract

An integrator-collector contains a time-corellated digital receiver for measuring, displaying, and recording fluid loss (including blood) from surgery or crisis procedures and for maintaining, displaying, and recording a count of secured surgical items such, as needles and sponges. The integrator-calculator computes total blood loss during surgery by means of an electronic beam, which upon activation by a surgical sponge, triggers the automatic conversion of the weight of the sponge into cubic centimeters of blood loss.

Fluid balance can be computed and reported from a corellation between blood lost, and loss from other fluids, such as vomitus and urine, and plasma intake and the intake of other fluids, such as clear intravenous fluids.

Claims

1. An integrator-collector apparatus for use in operating room procedures wherein blood from a patient is absorbed by surgical sponges, said apparatus comprising, in combination:

a) a means for counting surgical sponges which are prepared for use in an operating room procedure said patient by the breaking of surgical sterile seals;

b) a measuring means responsive to said means for counting for estimating the amount of blood absorbed by the surgical sponges actually used in said patient during said procedures;

c) a measuring means for estimating blood removed by suction from a patient during said operating room procedure;

d) a means for providing an estimate of incremental blood less during said operating room procedure and for providing an estimate of the total blood loss at the termination of the procedure, said means for providing said estimates of blood loss being operatively associated with each of said measuring means defined in parts (b) and (c), above;

e) a means for reporting and recording surgical specimens taken during the course of said operating room procedures and,

f) a means for providing labels for each of said specimens.

2. The apparatus of claim 1 wherein said counting means comprises indicia on external packaging on said surgical sponges and means for interpretation of said indicia to provide a numerical record of surgical articles and sponges bearing indicia.

3. The apparatus of claim 2 wherein said indicia are an integral part of said surgical seal.

4. The apparatus of claim 1 further comprising means for providing information to an operating surgeon relating to operating procedures or protocols.

5. An integrator-collector apparatus for use in operating room procedures wherein blood from a patient is absorbed by surgical sponges, said apparatus comprising, in combination:

a) a means for counting surgical sponges which are prepared for use in an operating room procedure on said patient by the breaking of surgical sterile seals;

b) a measuring means responsive to said means for country for estimating the amount of blood absorbed by the surgical sponges actually used in a patient during said procedure;

c) a measuring means for estimating blood removed by suction from said patient during said operating room procedure;

d) a means for providing an estimate of incremental blood loss during said operating room procedure and for providing an estimate of the total blood loss at the termination of the procedure, said means for providing said estimates of blood loss being operatively associated with each of said measuring means defined in parts (b) and (c) above; and

e) a means for measuring hematocrit percentage of said patient while simultaneously measuring hematocrit of irrigation fluid remnants, using said patient'"'"'s venous hematocrit as a standard;

whereby fluid balance can be maintained by accurate estimates of blood loss through irrigation.

6. The apparatus of claim 5 further comprises means to determine urine loss from said patient during the procedure and/or during acute periods following the procedure.

7. The apparatus of claim 6 wherein said means to determine said urine loss means for measurement of volume or weight of urine in a collection bag.

8. The apparatus of claim 6 wherein said means of measuring said urine loss means for measurement of volume and weight of urine in a collection bag.

9. The apparatus of claim 5 and adapted to count surgical articles comprising a ferrous metal wherein said means for counting comprise a magnetic touch pad and a means for monitoring impulses caused by said articles touching said pad and means for transmitting touches electronically to provide a count of said surgical articles comprising a ferrous metal.

10. The apparatus of claim 9 wherein said means for transmitting the touch electronically comprise a radio transmitter or an electronic cable.

11. An integrator-collector apparatus for use in operating room procedures wherein blood from a patient is absorbed by surgical sponges, said apparatus comprising, in combination:

a) a means for counting surgical sponges which are prepared for use in an operating room procedure on said patient by the breaking of surgical sterile seals;

b) a measuring means responsive to said means for counting for estimating the amount of blood absorbed by the surgical sponges actually used in with patient during said procedure;

c) a measuring means for estimating blood removed by suction from with patient during said operating room procedure;

d) a means for providing an estimate of incremental blood loss during said operating room procedure and for provides an estimate of the total blood loss at the termination of the procedure, said means for providing said estimates of blood loss being operatively associated with each of said measuring means defined in parts (b) and (c), above; and

,

e) in combination, means for providing an integrator function comprising a printing apparatus adapted to print on a paper strip, said printing apparatus being activated by impulses, said impulses causing printing of a count of surgical sponges, an estimate of blood absorbed in surgical sponges, an estimate of blood removed by suction, an estimate of incremental blood loss, and a count of surgical articles used during the procedure.

12. The apparatus of claim 11 wherein said impulses cause the printing of the date and time of every instrument, sponge, and needle used during the procedure.

13. The apparatus according to claim 12 further comprising means for corellating each material used in said operating room procedure with a billing price to said patient, and means for generating a record which can be used for billing purposes.
