Definitions

  • the present invention relates to an aspiration system for use in removing liquids discharged by the human body.
  • the invention may be used for removing body fluids and secretions other than urine.
  • One aspect of the invention relates to removal of wound exudate.
  • Wound exudate can be described as the liquid produced from chronic wounds, fistula, or acute wounds once haemostasis has been achieved. For centuries, the production of exudate was regarded as inevitable with certain types of wound, and inconsequential with respect to wound healing.
  • the negative pressure tends to draw tissue growth into the pores of a foam piece inside the wound dressing. This can result in discomfort to the patient during use of the device, and both discomfort and potential new tissue damage upon removal or changing of the dressing.
  • the wound is vulnerable to drying out of wound exudate. This condition is undesirable because exudate is now believed to contain a complex mixture of bioactive molecules that have both positive and negative effects. While removal of excess exudate is desirable, removal of all exudate may hinder rather than aid wound healing. Proper use of the wound dressing may depend to a large extent on the expertise of medical staff in assessing the rate of production of wound exudate at the wound site, and adjusting the suction accordingly.
  • an aspiration system and method for removing liquid other than urine, which liquid is discharged from the human body.
  • the system comprises a disposable body interface device having a liquid collection chamber.
  • a liquid sensor detects the presence of liquid within the chamber.
  • the application of aspiration suction to remove liquid from the liquid collection region is controlled responsive to the output of body fluids and secretions detected by the liquid sensor.
  • the body interface device may be a wound dressing to allow controlled draining of the liquid wound exudate.
  • the aspiration suction can be controlled to remove only excess wound exudate, according to the output of body fluids and secretions detected by the liquid sensor.
  • Fig. 1 is a schematic block diagram of a first embodiment of aspiration system for collecting and removing liquid wound exudate discharged by a wound of the human body, the diagram including an exploded sectional view of the wound dressing components.
  • Fig. 2 is a schematic sectional view showing, in exploded form, a modification of the wound dressing from Fig. 1.
  • Fig. 3 is a schematic diagram showing operation of the aspiration system in graphical form.
  • an aspiration system 10 for removing body liquid (other than urine) discharged or secreted by the human body generally comprises: a body interface device 14; and an aspiration unit 12 for applying suction to the body interface device 14 to aspirate the body liquid.
  • the present embodiment illustrates an aspiration system 10 specifically for removal of wound exudate from a wound site 18.
  • the body interface device 14 is in the form of (and is hereafter referred to as) a wound dressing, configured for fitting to the body at, or around, the wound site 18.
  • the field of wound dressings with exudate aspiration is quite unique, and very different from the field of, for example, urine removal.
  • Urine is usually discharged as a gush of liquid, and a urine removal system should remove all urine to leave the skin dry in order to avoid irritation and infection.
  • wound exudate is not discharged in a gush, and it is not desirable to remove all of the wound exudate.
  • the exudate contains a complex mixture of bioactive molecules that have both positive and negative effects. While removal of excess exudate is desirable, removal of all exudate may hinder rather than aid wound healing. Instead, the present embodiment aims to manage the amount of wound exudate, and remove excess from the wound site. As explained in more detail later, such management is facilitated in accordance with the principles of the invention by provision of a liquid sensor 30 for detecting liquid exudate in the wound dressing 14.
  • the liquid sensor 30 generates a signal 32 indicative of sensed liquid.
  • the sensor 30 may detect one or both of the following parameters: (i) proximity of liquid, and/or (ii) a quantity of liquid within sensing range.
  • the aspiration unit 12 is responsive to the sensor signal 32 in order to control the application of aspiration suction.
  • the wound dressing 14 is preferably attachable to the patient's skin 20 by means of an adhesive pad 26.
  • the adhesive pad 26 has a closed loop shape that circumscribes the periphery of the wound site 18.
  • the adhesive pad 26 extends over the wound site 18, and has perforations or apertures 27 to permit passage of exudate from the wound site 18 into the wound dressing 14.
  • the adhesive pad 26 is made of a skin-friendly medical grade adhesive. Examples of suitable adhesives include pressure-sensitive adhesives that may be any of hydrocolloid, polyurethane, acrylic, thermoplastic elastomer (TPE), hydrogel, or silicone-based.
  • the wound dressing 14 may have any suitable construction for covering the wound site 18, defining a liquid collection region and at least partly a local environment conducive to wound healing.
  • the wound dressing 14 may be the same as, or similar to, the dressings shown in any of the aforementioned U.S. Patent Nos. 4,969,880, 5,636,643, 5,645,081 , 7,216,651 , and/or U.S. Publication Nos. 2001/0029956 and 2006/0100594.
  • the wound dressing 14 typically comprises a cover 16 extending over the wound site 18, and overlapping healthy peri-wound tissue.
  • the wound dressing 14 may optionally contain or comprise a liquid handling material 24 (24a, 24b).
  • the liquid handling material 24 may, for example, be a material for absorbing exudate without gelling. Such a material may be non-woven and/or a foam. Such a non-woven material could be hydrophobic or hydrophilic, synthetic or natural.
  • the liquid handling material 24 may alternatively be, or comprise, a fibrous blend or fibrous material (e.g., a non-woven) that forms a cohesive gel when wetted with wound exudate.
  • a fibrous material can be provided, for example, by the wound contact layer of the Versiva ® dressing (ConvaTec Inc., Skillman, NJ) or by a fibrous mat of sodium carboxymethylcellulose.
  • a fibrous mat of sodium carboxymethylcellulose is available as AQUACEL ® dressing from ConvaTec Inc., as is a similar dressing further including silver.
  • Other exemplary materials for the liquid handling material 24 include MedicelTM, CarboxflexTM (which provides an odor absorbent layer with fibrous material for wicking liquid away from the odor absorbent), HyalofillTM (forming a hyaluronic acid- rich fibrous gel) or KaltostatTM (containing alginate) dressings from ConvaTec Inc. While the liquid handling layer 24 has the ability to absorb the exudate quickly, it also allows exudate to be pumped away under suction.
  • a combination of both a non-gelling liquid handling layer 24a and a fibrous gelling layer 24b may be used, for example, in distinct layers.
  • the layers 24a and 24b may be bonded to each other, or they may be contained as separate layer components within the wound dressing 14.
  • Fig. 1 illustrates an optional perforated screen 28 that may be used, for example, to enclose such layers 24a and 24b.
  • liquid handling layer 24b maybe perforated to allow excess exudate to be absorbed by liquid handling layer 24a.
  • An aspiration source connector 22 extends into the wound dressing 14 for delivering aspiration suction from the aspiration unit 12.
  • the connector 22 extends through the cover 16, although the connector 22 could enter the wound dressing 14 at any suitable point.
  • the point at which suction is applied is separated from the wound site 18 by at least a portion of the liquid handling material 24.
  • the point at which suction is applied is spaced from the wound site 18 by at least the gelling layer 24b, and preferably also by at least a portion of the non- gelling layer 24a.
  • a flexible conduit 35 couples the wound dressing 14 to the aspiration unit 12.
  • a releasable connector or an easy release coupling may be provided at one end, or both ends, of the conduit 35.
  • the flexible conduit 35 may be regarded as part of the aspiration unit 12 and/or part of the body interface device 14.
  • the flexible conduit 35 links the connector 22 to a suction source 40 within the aspiration unit 12.
  • the aspiration unit 12 comprises a power supply 38, an electronic control unit 44, and the suction source 40.
  • the power supply 38 is selected as one or more of: a replaceable battery, a rechargeable battery, radiation collection panels, and a mains power supply.
  • the power supply 38 includes a combination of a rechargeable battery and a mains power supply; such a combination allows portable operation when the aspiration system 10 is not connected to a mains power supply, as well as automatic recharging of the battery when the aspiration system 10 is coupled to a mains power supply.
  • the power supply 38 includes radiation collection panels, such as photovoltaic panels or cells for generating electricity from ambient light, which can improve autonomy of operation or for charging the rechargeable battery.
  • the power supply 38 may provide power for any one or more of: the electronic control unit 44, the liquid sensor 30 (if needed) and any power needed by the suction source 40.
  • the suction source 40 is an electric pump that operates under control of the electronic control unit 44.
  • the pump 40 could be a suction device based on diaphragm, peristaltic, volume displacement, spring, gravity, siphon, heat- recoverable metal drive, or an in-line pump.
  • the flexible conduit 35 is coupled through the pump 40 to a liquid collection chamber 42 for collecting exudate removed from the wound dressing 40.
  • the liquid collection chamber 42 may either be separate from the aspiration unit 12 (as illustrated) and coupled thereto with a suitable connector, or the liquid collection chamber 42 may be integral with and/or housed in the aspiration unit 12 (arrangement not shown).
  • the suction source 40 may comprise a vacuum chamber charged with a low pressure vacuum, and an electronically controlled valve for controlling application of suction from the vacuum chamber to the flexible conduit 35.
  • a pump may be provided for charging the vacuum chamber with the vacuum.
  • the liquid sensor 30 may be separate or separable from the wound dressing 14, enabling replacement of the wound dressing 14 without having to use a new sensor 30.
  • a means is preferably provided for releasably attaching the sensor 30 to the wound dressing 14.
  • the liquid sensor 30 may be permanently attached to the wound dressing 14 to form an integral unit. With permanent attachment, the liquid sensor 30 is intended to be disposed of with the wound dressing 14.
  • the sensor signal 32 is typically an electrical or electronic signal. However, other signal forms may be used as desired, for example, optical.
  • the sensor 30 may generate output signal 32 that varies in accordance with the sensed parameter(s).
  • the output signal 32 may be a varying analog signal (e.g., variable current or voltage), or the output signal 32 may be a digital signal (e.g., a quantized representation, or a variable pulsed representation).
  • the output signal 32 may be a logical (e.g., binary, or on/off) signal indicating whether or not the sensed parameter exceeds or is below one or more thresholds.
  • the liquid sensor 30 is preferably a non-contact sensor that is able to detect the presence or proximity of liquid without contact with the liquid.
  • the liquid sensor 30 generates an electrical output signal responsive to proximity of detected liquid.
  • the electrical signal is communicated to the aspiration unit 12 either via the conduit 35, or via a separate wire or wireless connector.
  • a wired electrical connector may also supply power from the aspiration unit 12 to power the liquid sensor 30.
  • the non-contact approach means that the liquid sensor 30 does not itself have to be in a sterile condition before use, thus avoiding the difficulty of, or risk of damage when, sterilizing the aspiration system 10 that does interface intimately with the body.
  • the feature of the liquid sensor 30 being coupled to the aspiration unit 12 by an electrical connector avoids the expense and fragility associated with using an optical fiber connection.
  • the liquid sensor 30 is separate from, or at least separable from, the wound dressing 14.
  • the wound dressing 14 may be a disposable item that may be manufactured inexpensively, and disposed of after a single use, or a limited number of uses.
  • the liquid sensor 30 may be more expensive, but may be intended to be used plural times, preferably, with a sequence of different wound dressings 14 used during wound treatment. This enables the aspiration system 10 to be produced and used very cost efficiently, since the disposable components are generally low cost. The higher cost components may be used multiple times, and may require infrequent replacement.
  • the liquid sensor 30 is a universal device that may be used with any of a plurality of different types of wound dressings 14
  • the non-contact sensor may be permanently attached to the wound dressing 14, and not be a re-usable item.
  • the liquid sensor 30 can take a variety of different forms.
  • the liquid sensor 30 is selected from: a capacitance sensor; an ultrasonic sensor; and a piezo-electric (or piezo-resonant) sensor.
  • a capacitance sensor detects proximity of liquid according to changes in the dielectric effect of liquid proximity, compared to air proximity. The dielectric effect affects the electric field in the active zone around the sensor, and thus, the effective capacitance in the sensor.
  • the capacitance is monitored by any suitable capacitance sensing circuit (not shown), such as an RC oscillator whose oscillation frequency and/or whether oscillation occurs, is dependent on the value of a resistor in combination with the effective capacitance of the sensor.
  • the oscillation in turn triggers an output stage, coupled to an output amplifier, to generate an output signal indicative of liquid presence.
  • the capacitance sensing circuit is preferably disposed near or at the liquid sensor 18 (e.g., as part of the liquid sensor 18 itself), or the capacitance sensing circuit can be disposed at the aspiration unit 12, or at a point along electrical connector 35.
  • a suitable capacitance sensor and capacitance sensing circuit are described in U.S. Patent No. 5,576,619, the contents of which are hereby incorporated by reference.
  • the ability to detect liquid has been tested using a capacitance "smart" sensor from SIE Sensors.
  • the sensor 30 of dimension 35mm (length) x 22mm (width) x 10mm (height) was affixed to the external wall of a body interface device 14.
  • the sensor 30 detected the presence of two test liquids, water and saline solution, as soon as the liquid was introduced, and provided an activation signal to the aspiration unit 12 within milliseconds.
  • the electric field from the sensor 30 is able to penetrate a wide variety of plastic components (e.g., polyethylene (PE), polypropylene (PP) and acrylics), either transparent or opaque, with great sensitivity.
  • An ultrasonic sensor works using the principle of sonar at the ultrasonic frequency range.
  • a transducer is resonated at a set frequency to convert electric energy into ultrasonic frequency range acoustic energy.
  • the ultrasonic acoustic waves are emitted towards a liquid collection region.

  • An example electro-optical liquid sensor is described in U.S. Patent No. 4,354,180, the content of which is incorporated herein by reference.
  • the liquid sensor may be disposed at a position 30a in contact with exudate inside the wound dressing 14, even if the sensor 30 does not rely on direct contact to detect the liquid.
  • a contact-based sensor 30 instead of a non-contact sensor 30.
  • An example of a contact-based sensor 30 is an electrical resistance sensor that detects liquid by conductance between electrodes in contact with the liquid.
  • the liquid sensor 30 may be held in an operative position with respect to the wound dressing 14 by a detachable attachment device (not shown) for releasably attaching the liquid sensor 30 to the wound dressing 14.
  • the detachable attachment device could comprise a peelable adhesive, or a peelable mechanical fastener, such as Velcro, or a mechanical coupling based on interference fitting, or other mechanical means.
  • a goal of this embodiment is to manage wound exudate, so that excess exudate is removed efficiently while leaving a residual amount of exudate in the wound dressing 14.
  • the sensor 30 and the control unit 44 co-operate to control the suction source 40 to keep the amount of exudate at a desired level. While the level could be indicated by a single threshold, preferably two thresholds THR-on and THR-off are used to introduce hysteresis to avoid the pump 40 being switched frequently.
  • the upper threshold THR-on defines a threshold at which the pump 40 is switched to an aspiration mode (e.g., turned-on), and the lower threshold THR-off defines a threshold at which the aspiration is reduced or deactivated (e.g., pump 40 turned off), to stop further substantial remove of exudate.
  • the amount of wound exudate will therefore fluctuate between the two thresholds, with the pump 40 being switched at successive time points T1 , T2 and T3, for example.
  • the thresholds THR-on and THR-off may optionally be adjusted manually by means of a manual control 46 of the aspiration unit 12. This may allow medical practitioners to control variably the "wetness" of the wound site 18, and allow different healing environments to be established as desired by a medical practitioner.
  • the control 46 may enable both thresholds to be adjusted. Alternatively, one of the thresholds may be fixed at a predetermined level. Alternatively, the difference between the thresholds may be variable, or may be fixed at a predetermined level.
  • the control unit 44 may function to apply the thresholds to the sensor signal 32.
  • the sensor 30 itself may apply the thresholds, such that the output signal 32 is already thresholded.
  • the sensitivity of the liquid sensor 30 may also be controlled by suitable positioning of the liquid sensor 30 with respect to the liquid handling material(s) 24 of the wound dressing 14 and/or by the thickness of the cover 16 in reducing the sensing field of the sensor 30. In one form, it might not be necessary to apply the lower threshold THR-off electronically. Instead, the sensor 30 may be sufficiently insensitive to liquid amounts below the threshold THR-off. Such an arrangement may be especially suitable when water-gelling material is used as the liquid handling material 24.
  • the aspiration system 10 as described herein provides significant advantages compared to the prior art, and can address or mitigate many of the drawbacks of the prior art, especially in terms of efficient aspiration of wound exudate, without drying out the wound site 18, and without requiring frequent changes of the wound dressing 14 to inspect the degree of wetness of the wound site 18.
