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.

Radiopaque marker for a surgical sponge
A surgical sponge comprises a plurality of radiopaque markers having a high radiographic density and a distinctive, visually recognizable shape. The markers have an x-ray density equivalent to at least about 0.1 g / cm2 of BaSO4. The markers produce an x-ray image with high contrast and a shape that is readily recognizable and differentiated from the images produced by other items and structures commonly seen in x-rays of post-operative patients. Owing to the distinctive, high contrast image produced by the markers, the sponge is reliably and unambiguously detected. This is so even in situations where the sponge is inadvertently left in the surgical wound. Discomfort, trauma, and possibly fatal consequences that might otherwise occur are virtually eliminated. The surgical procedure is carried out with decreased likelihood of a sponge being retained inadvertently.

Surgical implement detector utilizing a radio-frequency identification marker
InactiveUS7307530B2Control moreSevere possibilitySurgeryElectric/electromagnetic visible signallingModulation functionEngineering
A radio-frequency surgical implement detection system detects surgical implements in a surgical wound during and at the completion of a surgical procedure. Surgical implements, including surgical sponges or laparotomy pads, gauze pads and metallic surgical instruments, are individually attached to a non battery-powered, encapsulated radio-frequency marker. The marker comprises an integrated chip having a burnt-in memory code, which is broadcast through an antenna using a modulated carrier frequency. The code is received by an interrogating antenna of a detector. The interrogating antenna provides a power pulse, which is received by the antenna of the radio-frequency marker. The power pulse charges a capacitor, which proves power for the read function, carrier frequency modulation function and broadcast function of the integrated chip, permitting each marker-containing implement to be specifically identified.

Medical surgical sponge and instrument detection system and method
A magnetic detector locates magnetically tagged items, such as surgical sponges or instruments, introduced to and remaining in the body cavity of a surgical patient. The magnetic detector is a wand or probe that is manually handleable, and spatially manipulable and moveable, by an operator, such as a medical professional. The detector is moved about at a spatial location of an ambient magnetic field at the patient and operating table. A characteristic of the ambient magnetic field at the spatial location is saved by the detector. The detector is subsequently moved about at the same spatial location. If any magnetically tagged item is present in the vicinity of the detector during this subsequent movement at the spatial location, an anomalous magnetic effect is detected by comparison of the prior detection reading absent the tagged item to the detection reading in presence of the tagged item in the patient. The anomalous magnetic effect, and thus the tagged item, is locatable spatially in the patient, by three-dimensional sensor(s), arrays of sensors, and pluralities of arrays of sensors of the detector. The different detection readings with and without presence of the anomalous magnetic effect caused by presence of the tagged item in the patient are calculable as scalar, vector array, and / or gradient array determinations, according to the particular number and configuration of sensors in the detector.

Attachment of electronic tags to surgical sponges and implements
InactiveUS20050049564A1Avoid injuryEasy accessSurgeryDiagnostic markersEngineeringSurgical department
Externally detectable electronic article surveillance markers are attached to surgical implements, such as sponges and surgical instruments, appointed for use in a surgical wound. The attachment mechanism facilitates detection by an external interrogating field before the wound has been closed and the patient has left the operating table. The markers are responsive to the imposition of an interrogating field produced by an electronic article surveillance system. Use of the attachment mechanism and markers assure that the surgical implements are reliably detected and removed before completion of the surgical procedure. This technique eliminates the not infrequent mishap in which an implement is undiscovered at the time of surgery and remains indefinitely within the surgical cavity, often entailing dire consequences to the patient.

Miniature magnetomechanical tag for detecting surgical sponges and implements
InactiveUS7464713B2Serious consequenceEasy to operateDiagnosticsSurgeryEngineeringMechanical resonance
Externally detectable electronic article surveillance markers are attached to surgical implements, such as sponges and surgical instruments, appointed for use in a surgical wound. The attachment mechanism facilitates detection by an external interrogating field before the wound has been closed and the patient has left the operating table. The markers are responsive to the imposition of an interrogating field produced by an electronic article surveillance system. Markers contain one or more magnetomechanically responsive elements that are urged into mechanical resonance by the interrogating field. The ring-down of the resonance and the associated dipolar electromagnetic field provide a signal-identifying characteristic detected by a detection system. Upon detection, an audible or visible signal is triggered to alert relevant medical personnel to the need for follow-up care and removal of the offending item. The resonance occurs at a frequency ranging from about 70 to 300 kHz. Misadventures during operative procedures—especially those wherein implements remain undiscovered at the time of surgery and are retained indefinitely within the surgical cavity, often entailing dire consequences to the patient—are virtually eliminated. The attachment mechanism and markers assure that surgical implements are reliably detected and removed before completion of the surgical procedure.
