Definitions
- the present invention relates generally to medical devices and more specifically to detection methods and systems for determining a fill status of a canister of fluid used with medical devices.
- An alternative to this mechanical scrubbing of the open wound is a negative pressure wound closure device.
- This negative pressure wound closure device consists of a foam pad which is placed over the wound to form a relatively air tight and leak proof seal around the wound.
- the negative pressure wound closure device also has a vacuum pump fluidly coupled to the pad which is seated over the patient's wound. When the vacuum pump is activated, a negative pressure is created inside the pad covering the wound.
- the fluids expressed by the wound are removed through the foam pad by the negative pressure and transported through a tube connecting the foam pad to a canister.
- the canister collects the fluids removed from the wound. When the canister is full of fluid removed from the wound, the canister is emptied and reengaged to the vacuum system. Attempts have been made to alert the user when the canister is full of wound fluid. These methods have been aimed at directly measuring the amount of wound fluid in the canister.
- a method for detecting a fill status of a canister of fluid in a tissue treatment system includes creating a reduced pressure in a fluid communication path of the tissue treatment system and applying the reduced pressure to a tissue site. Fluid is collected from the tissue site in the canister. The reduced pressure is released, and a decay of the reduced pressure is measured. A fill status of the canister is determined from the measured decay.
- a reduced pressure treatment system in another embodiment, includes a canister fluidly connected to a tissue site and configured to receive fluid drawn from the tissue site under the influence of a reduced pressure.
- a reduced pressure source is configured to provide the reduced pressure and is fluidly connected to the tissue site by a fluid communication path.
- the fluid communication path includes a source conduit, the canister, and a target conduit.
- the canister is positioned between the reduced pressure source and the tissue site and is fluidly connected to the reduced pressure source by the source conduit.
- the canister is also fluidly connected to the tissue site by the target conduit.
- the reduced pressure treatment system further includes a sensing device in communication with the source conduit and configured to sense a pressure in the source conduit.
- a valve is provided in communication with the source conduit to selectively vent the reduced pressure.
- a processing unit is in communication with the sensing device and the valve.
- the processing unit is configured to open the valve for a selected amount of time, receive sensing data from the sensing device during the selected amount of time to determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.
- a reduced pressure treatment system in still another embodiment, includes a reduced pressure source to provide a reduced pressure.
- a porous pad is positioned at the tissue site and is fluidly connected to the reduced pressure source.
- a canister is fluidly connected between the porous pad and the reduced pressure source to collect fluid drawn from the tissue site.
- the system further includes a solenoid valve that is fluidly connected to a conduit between the canister and the reduced pressure source. Means is provided for determining a pressure decay in the conduit when the solenoid valve is opened.

- Figure 5 depicts a graphical representation of the results of a test conducted with a system employing a full canister detection method according to an illustrative embodiment of the present invention.
- Figure 6 depicts a graphical representation of the results of a test conducted with a system employing a full canister detection method according to an illustrative embodiment of the present invention.
- reduced pressure generally refers to a pressure less than the ambient pressure at a tissue site that is being subjected to treatment, hi most cases, this reduced pressure will be less than the atmospheric pressure at which the patient is located.
- vacuum and “negative pressure” may be used to describe the pressure applied to the tissue site, the actual pressure applied to the tissue site may be significantly less than the pressure normally associated with a complete vacuum. Consistent with this nomenclature, an increase in reduced pressure or vacuum pressure refers to a relative reduction of absolute pressure, while a decrease in reduced pressure or vacuum pressure refers to a relative increase of absolute pressure.
- tissue site refers to a wound or defect located on or within any tissue, including but not limited to, bone tissue, adipose tissue, muscle tissue, dermal tissue, vascular tissue, connective tissue, cartilage, tendons, or ligaments.
- tissue site may further refer to areas of any tissue that are not necessarily wounded or defective, but are instead areas in which it is desired to add or promote the growth of additional tissue. For example, reduced pressure tissue treatment may be used in certain tissue areas to grow additional tissue that maybe harvested and transplanted to another tissue location.
- a reduced pressure treatment system 11 includes a porous pad 20, or other distribution manifold positioned at a tissue site 15.
- the porous pad 20 is fluidly connected to a canister 17 by a target conduit 21.
- a reduced pressure source 19 is fluidly connected to the canister 17 by a source conduit 24.
- the reduced pressure source 19 delivers a reduced pressure to the tissue site through a fluid communication path, which is collectively comprised of the source conduit 24, the canister 17, and the target conduit 21.
- a solenoid or other suitable valve 18 is fitted to the source conduit 24 and serves to release the reduced pressure within the fluid communication path to the atmosphere when opened.
- the solenoid valve 10 may communicate with and be controlled by a processing unit 26, which is described in more detail below.
- the processing unit 26 may further communicate with a sensing device 28 that is used to determine a pressure in source conduit 24.
- the reduced pressure treatment system 11 is capable of reliably determining the fill status of a canister (i.e. whether the canister is full or not full of fluid).
- the system 11 relies on the volume of the fluid communication path being fixed and thus, relief of the vacuum from this known volume should occur within a set time after the valve 18 is opened.
- the processing unit 26 detects a blockage within the fluid communication path by any reliable blockage detection method, the processing unit 26 signals the valve 18 to open for a selected amount of time (e.g. 1 second) to vent the reduced pressure from the fluid communication path to atmosphere.
- the processing unit 26 receives sensing data from the sensing device 28 and monitors the pressure decay over this 1 second period. If the pressure decays quickly, then processing unit 26 determines that the canister 17 is full as the volume of the chamber being vented is small. Accordingly, the processing unit 26 will signal an alarm if a canister full status is determined.
- the processing unit 26 will conclude that the canister 17 is not full. The processing unit will then assume that the blockage condition originally detected is caused by an actual blockage in the target conduit 21 and not a canister full condition.
- the processing unit 26 in this particular instance may signal a separate alarm to indicate the presence of a blockage.
- the alarms used to notify a user of a canister full of wound fluid and a blockage in the target conduit 21 through which the wound fluid flows are separate and distinct.
- the decay of the reduced pressure may be determined in several ways. For example, the decay may be determined by measuring a reduction in the reduced pressure (i.e. increase in absolute pressure) over a selected amount of time after opening valve 18. As another example, the decay may be determined by measuring the amount of time that is required for the reduced pressure to drop to a threshold pressure. The decay in reduced pressure may also be determined by measuring the reduction in the flow rate in the source conduit 24 over the selected amount of time after opening valve 18. Other methods of measuring the decay of reduced pressure may also be used in a similar manner and are contemplated within the scope of the illustrative embodiments.
- the target conduit 21 connecting canister 17 to the porous pad 20, through which wound fluids flow may include optional valve 25.
- Closing valve 25 at the time of venting to atmosphere through valve 18 may indicate the volume within the canister that is empty. Deducing from this indication of empty volume and knowing the geometry of the canister, one may determine the level of fluid in the canister, and also may determine fluid flow rate from the tissue site 15 if periodically monitored.
- the processing unit 26 may be contained within a therapy unit housing 40 that may also house the reduced pressure source 19, the sensing device 28, and the valve 18.
- the processing unit 26 may be configured with one or more processors that are the same or different types.
- the processing unit 26 may include one or more processors, logic, analog components, or any other electronics that enable signals including information, such as fluid pressure at various locations in the system to be received.
- the processing unit 26 executes software 208 and may further be in communication with (i) a memory 210 for storing data and software code, (ii) an input/output (I/O) unit 218 for communicating with other devices and systems, such as a valves or sensing devices, wirelessly, via a wire, or via a memory input device, (iii) a storage unit 222 that may store one or more data repositories 226a-226n (collectively 226), such as a database having one or more files, (iv) an electronic display 234 that may or may not be touch-sensitive, and (v) one or more alarms 238 that are capable of signaling a user of the reduced pressure treatment system using audio, visual, or other signals.
- the software 208 may be configured to interface with each of the other devices (e.g., electronic display 234) to allow management and observation of the reduced pressure treatment.
- this figure depicts a graphical representation of the results of a test conducted with a system similar to reduced pressure treatment system 11.
- variation in decay time was noted against fill level at 125 mmHg for a closed canister.
- the canister was filled with various levels of water from empty to 500 ml in 50 ml increments.
- Negative pressure for the wound therapy was set to 125 mmHg and the system run until the pump stopped at slightly over the target pressure. Therapy was then turned off and natural leakage was applied to bring the pressure down to 125 mmHg. At this point, the valve was operated to vent the canister to atmosphere.
- the pressure profile was recorded at 10 samples per second.
- the same test was also conducted with a standard large wound attached to the system and resulted in the graphs of FIG. 6.
- FIG. 4 depicts a graphical representation of the results of a test in which differences in decay times between full and nearly full canisters at various pressures with large wound were observed.
- a standard large wound foam and dressing was prepared on a plastic base and fitted with a reduced pressure delivery pad to allow a syringe to inject liquid so as to fill the canister and cause a blockage alarm.
- Two sets of curves were plotted at therapy pressures of 50 to 400 mmHg, one at 450ml fluid level and one with a canister filled by wound drainage until a blockage alarm occurred.
- the 450ml value was chosen because as high a fill level as possible was required for the specific canister used, consistent with no blockage alarm occurring. This situation was contemplated to be the worst case scenario with the understanding that if the system could differentiate between the two situations at a high level, it would only be easier as the level is reduced.
- the canister was filled to 450ml and a pressure slightly above the target pressure was acquired.
- the vacuum pump was turned off and as leakage brought the pressure down to the target level, the vent valve was opened as described above.
- the canister was filled by injecting water into the wound and running under normal therapy conditions. Results of this test are shown in FIG.4.
- this figure depicts a graphical representation of the results of a test in which decay differences between full and other fluid levels at 350mmHg with a large wound were observed.
- a standard large wound was prepared as in the test of figures 3 and 4 and pressure curves plotted at 350mmHg for fluid levels from empty to 500 ml, filling externally. This procedure was done under direct control as in the tests described above. The system was run under normal therapy at 200 mmHg and fluid injected into the wound until a blockage alarm occurred. Direct control was resumed at 350 mmHg and the last curve plotted.
- the graph in Figure 4 indicates that there is distinct grouping in the data.
- the pressure fell to under 10 mmHg in less than 0.8 seconds, irrespective of the therapy pressure.
- the time to 10 mmHg was three seconds or more. The differential may have improved if the time to a percentage of initial rather than to an absolute pressure were measured.
- Figure 5 confirms that the decay times for all fill levels from empty to 500ml take a substantial time to fall to near-zero levels from 350 mmHg.
- the fastest decay rate (500ml) fell to about 20 mmHg after four seconds and was still around 10 mmHg after 10 seconds.
- the blocked curve fell to virtually zero (under 3mmHg) in less than a second.
- the system and method disclosed in the instant application improves upon existing negative pressure treatment systems by reliably alerting the user of the system that the wound fluid canister is full and may have to be emptied.
- the systems and methods disclosed herein are able to measure the decay of the negative pressure. If the negative pressure inside the fluid communication path decays rapidly, then the system determines that the canister is full and activates an alarm notifying the user that the canister is full of wound fluid. If the negative pressure inside the fluid communication path decays slowly, then the system determines that there is a blockage in the system that should be removed and notifies the user by activating an alarm.
