Definitions

  • the invention relates to identification and detection apparatus and, more particularly, to apparatus for identifying and detecting an individual at a particular location without that individual's knowledge.
  • Health facilities all share a common problem: some of the patients prematurely leave before completing their Q treatment and without first receiving permission to leave from an appropriate medical authority at the facility, e.g. their doctor or the like.
  • the health facility remains liable to that patient and to members of the public for any harm that patient causes either to himself or to others and regardless of any reasons that patient has to prematurely leave the facility. Thus, in instances where patients prematurely leave a health facility and do not first provide an informed consent or are legally incapable of doing so, the health facility bears a very heavy legal liability.
  • hospital or medical personnel may not realize a patient has prematurely left until well after that patient has physically left the facility. For example, a patient may join a crowd that is walking right past a security guard at the exit of the hospital and, as a result, not be noticed by the guard.
  • the hospital or health facility bears the ultimate responsibility of first locating that patient and advising him to return and, if that patient has the mental capacity to legally provide an informed consent and insists on not returning, then obtaining such a signed informed consent against returning; or alternatively, if that patient lacks the legal capacity to give an informed consent, physically retrieving that patient and then properly confining him.
  • an object of the present invention is to provide apparatus for detecting and identifying a subject without that subject's knowledge.
  • a specific object is to provide such apparatus that does not need to be visually perceived in order to detect the subject at a particular location.
  • Another specific object is to provide a patient identification device for use in such apparatus which is inexpensive and expendible.
  • a detectable element e.g. a magnetic strip which acts as a flux-gate device or a computer controlled transceiver
  • a transmitter generates an interrogating field into a localized area.
  • the concealed detectable element Whenever the individual wearing the object moves through the area, the concealed detectable element generates a response, e.g. harmonics of the interrogating field from the magnetic strip or a response message from the transceiver. This response is detected by a receiver which, in turn, triggers an annunciator to alert others to the identification and location of the individual.

  • This detection equipment consists of detection circuitry 50 and transmitting and receiving antennas 40.
  • Detection circuitry 50 in a manner to be explained shortly, is typically positioned at the side of doorway 20 and detects the passage of the patient identification tag therethrough.
  • the patient identification tag includes a strip, of pre-defined dimensions, of a magnetic material having a relatively low coercivity and a relatively high permeability.
  • Detection circuitry 50 operating in conjunction with a well-known transmitter (see FIG. 2) , located within transmitting and receiving antennas 4 ⁇ , emits a localized magnetic field into the opening of doorway 20. This field covers substantially the entire opening of doorway 20.
  • Lead 45 carries the output of the transmitter to a transmitting antenna located within transmitting and receiving antennas 40.
  • the magnetic strip located within patient identification wrist band 30 is excited by the magnetic field present in doorway 20 and, in response thereto, generates frequencies at harmonics of the frequency of the exciting field.

  • the magnetic strip contained within identification wrist band 30 will produce both even and odd order harmonics, with the second harmonic having the largest amplitude.
  • the transmitter produced a magnetic field having only an "ac” component, then only odd order harmonics would be generated by the magnetic strip, with the third harmonic having the largest amplitude.
  • a well-known receiver located within detection circuitry 50, operating in conjunction with a receiving antenna located within transmitting and receiving antennas 40, detects one of these harmonics.
  • Lead 42 routes signals from the receiving antenna to detection circuitry 50 and, in particular, to the receiver contained therein.
  • detection circuitry 50 supplies an appropriate indication, via leads 55, to activate an annunciator located at a central site, e.g. a central reception station or guard station, situated within the hospital. This annunciator, typically a audible alarm, alerts hospital personnel that a patient wearing an identification wrist band has just transitted through doorway 20.
  • An alarm reset switch located at the central site provides a signal through lead 58, to reset ("re-arm") the receiver and thereby silence the annunciator until another person wearing an identi ication wrist band transits through the doorway.
  • the receiver could be designed in a well-known fashion to silence the annunciator and re-arm itself after a given amount of time, e.g. a few minutes, has elapsed if the alarm reset switch has not been depressed during this intervening interval of time.
  • FIG. 2 depicts a block diagram of the system shown in FIG. 1.
  • Detection circuitry 50 contains transmitter 52 and receiver 54. This transmitter, in conjunction with transmitting antenna 43, produces the exciting magnetic field. Transmitting antenna 43 can typically have one of many different geometries, a loop or a suitable coil, of appropriate dimensions.
  • Receiver 54 in conjunction with receiving antenna 47, receives the harmonics generated by the magnetic strip. In response thereto, receiver 54 applies an appropriate signal, via lead 55, to annunciator 95 situated within circuitry 90 located at the central site.
  • Alarm reset switch 98 also '-located at the central site, is used to re-arm the receiver, as discussed hereinabove.
  • FIG. 3 depicts a top view of identification wrist band 30 used in the inventive patient identification and detection system shown in FIG. 1.
  • This wrist band is generally formed of two (or more) layers of an inert very inexpensive material, typically plastic, that have been sandwiched together and joined at their edges. Access is afforded to a space existing between these layers of plastic into which the identification tag is inserted.
  • the top surface of the wrist band is substantially transparent to permit anyone to view the writing on the identification tag.

  • illustrative wrist band 30 shown in FIG. 3 comprises a substantially widened section 300 which is attached at one end thereof to slender elongated section 310.
  • Widened section 300 is substantially transparent with a slit 355 near one end thereof which provides access to rectangular space 358 located within this section.
  • Identification tag 350 is inserted through slit 355 into space 358 so that the writing on the tag is visible through the transparent top surface of the wrist band.
  • the wrist band is wrapped around a patient's wrist and then secured in place.
  • a clasp comprised of eyelet 345 and mating pin 340 secures the wrist band around the patient's wrist.

  • the identification strip is a slender strip of paper or plastic or other suitable material with a writing surface on one side which carries the desired patient information. Patient information can either be handwritten and/or typed onto the writing surface.
  • Magnetic strip 351 is affixed, usually by means of a well-known adhesive, to the rear side of identification strip 352. As noted, this magnetic strip is relatively long and has a very thin cross-section. As such, the magnetic strip imparts little additional cross- sectional area to identification strip. Hence, for purposes of illustration, the cross-sectional area of magnetic strip 351 shown in the figures has been grossly exaggerated.

  • FIG. 7 depicts a cross-sectional view of identification tag 350 taken along lines 7-7 shown in FIG.5.
  • identification tag 350 could be formed of two laminated strips which together sandwich the magnetic strip thereby hiding the magnetic strip from- view.

  • a laminated identification tag is shown in FIG. 8.
  • tag 850 contains strips 820 and 830 which together sandwich magnetic strip 351. Both strips 820 and 830 have an outwardly facing surface (e.g. surface 840 on strip 830) on which patient information can be written and as such patient information can be written on either side of identification tag 850.

  • an identification tag is first connected to processing circuitry 800 through small well-known terminals 618. Once the identification tag is connected to processing circuitry 800, bi-directional serial communication is established between microprocessor 630 located within processing circuitry 800 and. microprocessor 720 located within identification tag circuitry 700. In response to this, microprocessor 630 signals the operator that the identification tag is ready to be programmed and then queries the operator for patient information using the display and operator controls 698. The desired information is then entered by the operator using display and operator contrpls 698 — typically a video terminal and a keyboard. Because a relatively large amount of integrated memory can be incorporated into the identification tag, significantly more information than patient name, blood type and hospital name can be entered into the memory.

Abstract

Appareil destiné à identifier une personne, par exemple un patient (10), et à déterminer si cette personne a abusivement quitté son lieu d'internement tel qu'un établissement hospitalier ou psychiatrique. Généralement, ledit appareil d'identification et de détection (30, 40, 50) utilise un élément détectable, par exemple une tirette magnétique (351), qui joue le rôle d'un dispositif à porte de flux ou d'un émetteur-récepteur commandé par ordinateur, ladite tirette étant incorporée à un objet porté par l'individu, par exemple un bracelet (30), un pendantif ou un badge d'identification. Un émetteur (52) produit un champ d'interrogation dans une zone localisée. L'élément détectable produit une réponse, par exemple les harmoniques du champ d'interrogation provenant de la tirette magnétique ou un message de réponse provenant de l'émetteur-récepteur. Cette réponse est détectée par un récepteur (54), qui, à son tour déclenche un annonciateur (95).
