Abstract

Systems and methods for managing surgical sponges. A dispenser assembly coupled to a main support includes an internal or first storage location to removably receive a carton of sponge sorters, and an external or second storage location to removably support a carton of surgical draping. At least one arm may be supported on the housing and movable between an undeployed position and a deployed position. The arm may include weighing means to measure a weight of the surgical sponge being disposed in a sponge sorter supported by the arm. The arm may be a cantilever and abeam load cell may be disposed within a channel of a beam. A processor may determine fluid weight based on measured weight and dry weight correlated with the surgical sponge being counted out as detected with a data reader. The processor may estimate blood loss to be displayed on a display.

Claims (33)

1 . A system for managing surgical sponges, the system comprising:

a base;

a main support extending from the base; and

a dispenser assembly supported on the main support, the dispenser assembly comprising a housing defining a first storage location that is internal to the housing with the first storage location configured to removably receive a carton of sponge sorters, and a second storage location that is external to the housing with the second storage location configured to removably support a carton of surgical draping,

wherein the housing of the dispenser assembly comprises an upper wall defining the second storage location.

2 . The system of claim 1 , further comprising an arm pivotably coupled to the housing and pivotable with respect to the housing between an undeployed position in which the arm is disposed within a recess of the housing, and a deployed position in which the arm extends beyond sidewalls of the housing.

3 . The system of claim 2 , further comprising a mounting bracket pivotably coupling the arm with the housing, wherein the arm is cantilevered.

4 . The system of claim 3 , wherein the arm comprises a load cell configured to sense a change in measured weight of items supported by the arm.

5 . The system of claim 4 , wherein the arm further comprises a beam defining a channel, and wherein the load cell is disposed in the channel and coupled to the beam.

6 . The system of claim 5 , wherein the arm further comprises a loading bar, and wherein the loading bar is coupled to the load cell at an end or portion opposite to the beam.

7 . The system of claim 4 , further comprising:

a handle coupled to the main support;

a module base coupled to the main support and positioned between the handle and the dispenser assembly; and

an electronics subassembly disposed within the module base.

8 . The system of claim 7 , wherein the electronics subassembly comprises a processor in communication with the load cell, the system further comprising a display removably coupled to the module base and in communication with the processor, wherein the display is configured to display an estimated blood loss as determined by the processor based on the measured weight as sensed by the load cell.

9 . The system of claim 1 , wherein the housing comprises an upper shell, and a lower shell coupled to the upper shell, wherein the upper shell comprises a front wall defining a front opening in communication with the first storage location.

10 . The system of claim 9 , wherein the lower shell comprises a lower wall sloping downwardly towards the front wall.

11 . The system of claim 9 , wherein the housing defines a rear opening in communication with the first storage location, wherein the rear opening is larger than the front opening.

12 . A system for managing surgical sponges, the system comprising:

a base;

a main support extending from the base;

a dispenser assembly supported atop the main support and comprising a first storage location for removably receiving a carton of sponge sorters, and a second storage location for removably receiving a carton of surgical draping; and

an electronics subsystem supported on the main support, the electronic subsystem comprising a module base, a display removably coupled to the module base, and a data reader removably coupled to the module base, wherein the electronics subsystem is supported on the main support between the base and the dispenser assembly,

wherein the main support is hollow and configured to accommodate a power cable, and defines an opening in a front side of the main support to facilitate electrical connection between the power cable and the electronics subsystem, and wherein the main support defines a second opening on a rear side of the main support from which the power cable extends to be coupled to an external power source.

13 . The system of claim 12 , further comprising a handle supported on the main support, the handle positioned between the electronics subsystem and the base.

14 . The system of claim 12 , further comprising an arm coupled to the dispenser assembly and comprising a load cell configured to detect a change in measured weight of items supported by the arm.

15 . A system for managing surgical sponges, the system comprising:

a base;

a main support extending from the base; and

a dispenser assembly supported atop the main support and comprising a first storage location for removably receiving a carton of sponge sorters, and a second storage location for removably receiving a carton of surgical draping; and

an arm pivotably coupled to the dispenser assembly between an undeployed position in which the arm is disposed within a recess of the dispenser assembly, and a deployed position in which the arm extends beyond sidewalls of the dispenser assembly.

16 . The system of claim 15 , further comprising a mounting bracket pivotably coupling the arm with the dispenser assembly, wherein the arm is cantilevered.

17 . The system of claim 15 , further comprising an arm coupled to the dispenser assembly and comprising a load cell configured to detect a change in measured weight of items supported by the arm.
