Definitions

  • the method further includes providing a reduced-pressure source; transmitting an ID inquiry signal from the remote base unit to the first, wireless, reduced-pressure dressing; receiving the ID inquiry signal at the first, wireless, reduced-pressure dressing and producing an ID message signal; transmitting the ID message signal from the first, wireless, reduced-pressure dressing to the remote base unit; receiving the ID message signal at the remote base unit; determining if the ID message signal is on an approved list; and activating the reduced-pressure source to provide reduced pressure to the distribution manifold if the ID message signal represents a dressing that is on the approved list or indicating an error if the ID message signal represents a dressing that is not on the approved list.
  • FIGURE 4 is a schematic top view of an illustrative embodiment of a first, wireless, reduced-pressure dressing
  • the second processor 148, RFID reader 146, first RFID antenna 122, and first processor 124 may be configured to perform the following steps: transmitting an ID inquiry signal from the remote base unit 1 14 to the first, wireless, reduced- pressure dressing 1 12; receiving the ID inquiry signal at the first, wireless, reduced-pressure dressing 112 and producing an ID message signal; transmitting the ID message signal from the first, wireless, reduced-pressure dressing 1 12 to the remote base unit 1 14; receiving the ID message signal at the remote base unit 114; determining if the ID message signal represents a dressing on an approved list; and activating the reduced-pressure source 1 16 to provide reduced pressure to the distribution manifold 118 if the ID message signal represents a dressing that is on the approved list (or otherwise acceptable) or indicating an error if the ID message signal represents a dressing that is not on the approved list.
  • a dissolution element 162 is disposed proximate to the membrane 160 and is adapted to (or operable to) change the membrane 160 from an occlusive state to a non- occlusive state.
  • the dissolution element 162 may be activated by the first processor 124 to produce the activating event. In other embodiments, the dissolution element 162 may be activated by the second processor 148 or an external stimulus.
  • FIGURE 5 another illustrative embodiment of a system 100 for treating at least one tissue site 102 with reduced pressure is presented.
  • the system 100 includes a first, wireless, reduced-pressure dressing 1 12.
  • the system 100 is analogous in most respects to the system 100 of FIGURE 1, except that a reduced-pressure source 1 16 is a micro-pump 117, e.g., a piezoelectric pump, and is adjacent to the distribution manifold 1 18.
  • an absorbent layer 1 19 is also explicitly included.
  • "adjacent" means next to, in the vicinity of, and also includes in.
  • a dedicated battery 166 may be coupled to the micro-pump 1 17 to provide power to the micro-pump 117.
  • a vent line 168 may be used to allow the micro-pump 1 17 to vent or exhaust outside of the first, wireless, reduced-pressure dressing 112.
  • a first processor (analogous to first processor 124 of FIGURE 3) that is associated with a WISP or RFID device 170, may be instructed by the remote base unit 114 to deliver a control signal to the micro-pump 117 when necessary.
  • the remote base unit 1 14 transmits an ID inquiry signal to the first, wireless, reduced-pressure dressing 1 12.
  • the first RFID antenna 122 receives the ID inquiry signal.
  • the ID inquiry signal energizes the first processor 124 and provides an identification request to the first processor 124.
  • the first processor 124 transmits an ID message signal from the first RFID antenna 122 to the RFID reader 146 on the remote base unit 114.
  • the remote base unit 1 14 waits for the ID message signal at interrogatory 206.
  • the second processor 148 waits a predetermined time for the ID message signal. If the ID message signal is not received during the predetermined time, the process proceeds to step 208 where an error flag is posted and the process ends at 210.
  • the error flag may include posting a message for display at control panel 158 or sounding an alarm or providing other notification. If the ID message signal is received, the process proceeds to interrogatory 212.
  • the second processor 148 compares the elapsed time of the first chronograph, Tl, with a maximum time, Tlmax. If the maximum time has been exceeded, the process continues to step 226. At step 226, the second processor 148 posts an error flag and the process ends at 228. The error flag may include sounding an alarm or displaying a message on the control panel 158 or otherwise notifying the user of a problem. If the maximum time has not been exceeded, the process returns to step 218. The loop (218, 220, 222, 218, ...) continues until the maximum time is exceeded or a suitable reduced pressure is reached.
  • FIGURES 6A-6B The process presented in FIGURES 6A-6B is one illustrative embodiment. Many embodiments are possible. Other process flows may include analogous instructions for receiving temperature message signals from the second sensor 142 or other data depending on the sensor type. In another illustrative embodiment, the activation step may follow the steps required to confirm an approved dressing.
  • the method may further include determining if the first pressure message signal is greater (on an absolute pressure scale) than a target pressure, and if greater than the target pressure, then activating the reduced-pressure source, and if less (on an absolute pressure scale) than the target pressure, then deactivating the reduced-pressure source.
  • a system for treating at least one tissue site with reduced pressure includes: a first, wireless, reduced-pressure dressing for disposing proximate to the tissue site.
  • the first, wireless, reduced-pressure dressing comprises: a distribution manifold, a sealing member covering at least a portion of the distribution manifold, a reduced-pressure interface for providing reduced pressure to the distribution manifold, a first RFID antenna, a first processor coupled to the first RFID antenna, a first sensor coupled to the first processor, a membrane, wherein the membrane is initially occlusive and wherein the membrane covers at least a portion of the reduced-pressure interface and is adapted to prevent fluid flow when in the occlusive state, a dissolution element proximate to the membrane that is operable, when activated, to change the membrane from an occlusive state to a non-occlusive state, a remote base unit comprising a RFID reader and a second processor; and a reduced-pressure source fluidly coupled to the distribution manifold.
