- FIGS. 1A and 1B are schematic diagrams of an embodiment of an intelligent
medical device barrier 10 in accordance with the teaching of the present invention.Cover 12 is formed of a similar shape ofprobe head 13 and probe handle 14 ofprobe 11.Cover 12 is received overtip 8 and probehead 13 and is pulled or rolled up overshaft 9 ofprobe head 13 in order to be used as a barrier to probe 11.Cover 12 can be received overportion 7 of probe handle 14 for insuringshaft 9 is completely covered bycover 12. For example, probe 11 can be a probe used for examination of the prostate as described in U.S. Pat. No. 6,142,959, hereby incorporated by reference into this application. - Retaining means15 secures
cover 12 in place onprobe handle 14. For example, retaining means 15 can be a detent, tab, snap catch, hook or ring forcoupling cover 12 to probe handle 14 which inserts, snaps or twists into place onprobe handle 14. Retaining means 15 provides expeditious attachment ofcover 12 to probehead 13. For example, cover 12 can be installed or removed onprobe head 13 and probe handle 14 in less than about 10 seconds. Retaining means 15 can be coupled to cover 12. Alternatively, retaining means 15, such as a ring, can be placed overcover 12 to presscover 12 against probe handle 14. - One or
more sensors 16 can be attached to one or more predetermined positions onhandle 14, retaining means 15 or cover 12 for sensing whencover 12 is in place properly onprobe head 13. In one embodiment illustrated in FIG. 2A,sensor 16 is coupled to retaining means 15 and retaining means 15 is attached to cover 12. Retaining means 15, such as a detent, is coupled to an indentation or protrusion in probe handle 14. Upon probe handle 14 engaging retaining means 15,sensor 16 is activated to indicate thatcover 12 is in place onprobe handle 14. If it isdetermined cover 12 is in place properly onprobe head 13,probe 11 can be activated to enable its use for examination. -
Sensor 16 provides data, such as an identification. The identification can include a lot number or serial number forcover 12. Alternatively, the identification can be a different state ofsensor 16, such as a different color ifcover 12 had been previously used. Data fromsensor 16 is forwarded toelectronic unit 20 overlink 19.Electronic unit 20 determines from the identification ifcover 12 had been previously used. If it isdetermined cover 12 has not been previously used,electronic unit 20 can be adapted to activateprobe 11 to enable its use for examination. If it isdetermined cover 12 has been previously used,electronic unit 20 can deactivateprobe 11 to prevent its use for examination. -
Sensor 16 can also provide an expiration date such as a manufacture date plus a shelf life overlink 19. If it isdetermined cover 12 is expired,electronic unit 20 can deactivateprobe 11 to prevent its use in examination.Sensor 16 can also provide calibration data to probe 11 for operation ofprobe head 13. - One or
more sensors 17 receive information upon use ofprobe 11.Sensor 17 can be coupled to any position ofcover 12. Alternatively,sensor 17 can be coupled to retaining means 15 or probe handle 14.Sensor 17 can link through probe handle 14 toelectronic unit 20 overlink 19. Data acquisition ofprobe 11 fromsensor 17 can be forwarded overlink 19 toelectronic unit 20. -
Sensor 16 can be an integrated circuit.Electronic unit 20 can include a processor, display device, storage unit and central unit. In one embodiment,electronic unit 20 can be a personal computer. Alternatively,electronic unit 20 can be housed in probe handle 14. In this embodiment,electronic unit 20 comprises a processor and storage unit.

For example, link 19 can be a wireless link, optical link or direct electrical connection. Electronic coding ofsensor 16 andsensor 17 can be performed by radio frequency (RFID) tag, RFID direct connect, EEPROM, electrical fuse, ink and barcode. For example, in the use of a RFID-tag or RFID direct connect a read/write integrated circuit is used insensor 16 and/orsensor 17 in probe handle 14. In RFID-tag,sensor 16 orsensor 17 communicates over a wireless link to probehandle 14. In RFID-tag direct connect,sensor 16 orsensor 17 communicates over a direct link to probehandle 14. In EEPROM, a plurality of electrical contacts are used to communicate betweensensor 16 orsensor 17 to probe handle 14 to provide an erasable data, such as an identification number or serial number. Alternatively, for example, four electrical contacts can be used in EEPROM. In electrical fuse, electrical contacts are used to communicate betweencover 12 and probe handle 14. For example, two electrical contacts can be used to form an electrical fuse. For example, in the use of ink, the ink can disappear from transparent to opaque upon exposure to heat, temperature or UV. An optical interrupter can be used to detect the change in the ink state. Accordingly, upon use ofprobe 11, probe handle 14 can transmit a wavelength of a predetermined intensity for changing the ink state ofsensor 16 orsensor 17. In the case of a barcode, the barcode ofsensor 16 orsensor 17 is written oncover 12 or on a label oncover 12.Electronic unit 20 can include a barcode reader for reading the barcode or the barcode reader can be located onprobe 11. -
Cover 12 can be formed to have a shape similar to the medical device to provide a barrier to protect the medical device. For example, as shown in FIG. 2A, cover 12 can have various cross sectional shapes along lines A-A of FIG. 2B, B-B of FIG. 2C and C-C of FIG. 2D which correspond to the shape ofprobe 11 and allow pivoting ofprobe head 13. - Coupling means21 can be used to retain
cover 12 onprobe 11 in addition to retainingmeans 15. For example, coupling means 21 can be a hook. - In one embodiment, cover12 can include pull-
tab 22 which is pulled to removecover 12 fromprobe 11. Pull-tab 22 is attached to reducedthickness portion 24 ofcover 12.Reduced thickness portion 24 ofcover 12 can tear when pull-tab 22 is pulled. Accordingly, after pull-tab 22 tears reducedthickness portion 24,probe 11 is unable to be re-used in a subsequent procedure and insures single use ofcover 12. - FIGS. 3A-3E illustrate an alternate embodiment of an intelligent
medical barrier device 30 in accordance with the teachings of the present invention.Cover 29 is coupled tocollar 30 atbonding portion 31 ofcover 29, as shown in FIG. 3A. -
