Definitions

  • the present invention relates to an aspiration system for use in an aspiration system for removing liquids, discharged by the human body. Aspects of the invention are particularly directed to the problems of urine removal.
  • Urinary management is of critical need in the acute and long term care settings. Urinary issues are generally grouped into two primary categories: failure to drain; and failure to contain. In the case of failure to drain, the patient cannot spontaneously drain urine from the bladder. The general solution to this problem is to catheterize the patient. In the case of failure to contain, the patient cannot contain the urine within their body until a convenient and expedient time. When patients are not conscious or cognizant, they are typically catheterized. Patients who are aware but non-ambulatory often utilize a manual collector for assistance, such as a bedpan, a male urinal, or an adult diaper. These can be cumbersome to use, and sometimes result in spills on or around the patient. Also, such manual collectors may require frequent changes, placing additional burden on caregivers. When it is desired to monitor the urine output, very often medical staff catheterize a patient even when catheterization is not otherwise required. Catheterization provides a means by which urine can be monitored more easily than with a manual collector.
  • UTIs catheter-related urinary tract infections
  • U.S. Pat. Nos. 5,002,541, 4,747,166 and 4,631,061 describe human urine aspiration systems.
  • the urine aspiration systems include an electric pump for applying suction to a urinal.
  • the urinal includes a liquid sensor for automatically activating the pump when the presence of liquid urine is detected.
  • the three patents all describe liquid-contact sensors in the form of electrodes forming a normally open circuit that is closed by electrical conduction through liquid, when the sensor is contacted by liquid.
  • the sensor is necessarily used in close proximity to the sensitive genital area, increasing the concerns of leakage of current that is applied by the electrodes.
  • optical fibres are expensive items, and integrating these into the urinal or tubing increases the cost of the urinal or tubing, which are preferably disposable for hygiene reasons.
  • electro-optic part is remote from the urinal, and has to be connected by delicate and expensive optical fibres, making the system delicate and expensive as a whole.
  • FIG. 1 is a schematic block diagram of a first embodiment of aspiration system for collecting and removing liquid discharged by the human body.
  • FIG. 2 is a schematic plan view of a pair of briefs as an overgarment.
  • FIG. 3 is a schematic side view of a second embodiment showing an implementation of a capacitive, ultrasonic or piezo-electric non-contact liquid sensor.
  • FIG. 4 is a schematic side view of a third embodiment showing an implementation of an electro-optic non-contact liquid sensor.
  • FIG. 5 is a schematic side view of a fourth embodiment showing an implementation of a temperature, non-contact liquid sensor.
  • an aspiration system 10 for removing body liquid discharged by the human body generally comprises an aspiration unit 12 and a body interface device 14 coupled to the aspiration unit 12 by means of a flexible conduit 16 .
  • the flexible conduit 16 may be regarded as part of the aspiration unit 12 and/or part of the body interface device 14 .
  • the body interface device 14 is configured for fitting to the body at, or around, the site of discharge of the body liquid desired to be collected.
  • the body interface device 14 is preferably attachable to the body by means of an adhesive pad 15 that surrounds the site of discharge.
  • the body interface device 14 is configured to fit at the genital region of a male or female wearer, or a surgical urostomy.
  • the body interface device 14 is in the form of a snug-fitting urinal (as illustrated herein).
  • the body interface device 14 is in the form of a male urinal or a condom (not illustrated).
  • the body interface device 14 is in the form of a stoma fitment (not illustrated).
  • the present embodiment is especially suitable for removing urine, since urine removal is most challenging in terms of the volume of the liquid to be removed and the speed of liquid discharge. This can distance the field of urine removal from other liquid collection systems.
  • the speed of response of the aspiration system 10 to detect and remove the liquid is a significant factor in the ability of the aspiration system 10 to manage a urine discharge. Also, there are significant challenges in terms of cost versus hygiene of the aspiration system 10 .
  • the aspiration system 10 includes a liquid sensor 18 for detecting the presence of liquid discharged by the body and collected at the body interface device 14 .
  • the liquid sensor 18 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 18 generates an electrical output signal responsive to proximity of detected liquid.
  • the electrical signal is communicated to the aspiration unit 12 by means of an electrical connector 20 .
  • the electrical connector 20 may be integrated with, or separate from, the flexible conduit 16 .
  • the electrical connector 20 also supplies power from the aspiration unit 12 to power the liquid sensor 18 .
  • the feature of the liquid sensor 18 being a non-contact sensor provides significant advantages because: (i) the non-contact approach automatically avoids the concerns about passing an electrical current through the liquid in contact with the skin. Instead, there is no direct contact between the liquid sensor 18 and the liquid; (ii) the non-contact approach means that the liquid sensor 18 is not contaminated by touching the liquid. This allows the liquid sensor 18 easily to be reused with a different body interface device 14 ; and (iii) the non-contact approach means that the liquid sensor 18 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 18 being coupled to the aspiration unit 12 by an electrical connector 20 avoids the expense and fragility associated with using an optical fiber connection.
  • a preferred feature of the invention is that the liquid sensor 18 is separate from, or at least separable from, the body interface device 14 .
  • the body interface device 14 is a disposable item that may be manufactured inexpensively, and disposed of after a single use, or a limited number of uses, according to the specific body interface device 14 .
  • the liquid sensor 18 is more expensive, but is intended to be used plural times, preferably, with a sequence of different body interface devices 14 . 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 18 is a universal device that may be used with any of a plurality of different types of body interface devices 14 , such as a female urinal, a male condom, a urostomy body fitment, or a catheter.
  • the liquid sensor 18 can be permanently attached to the body interface device 14 .
  • the liquid sensor 18 can take a variety of different forms.
  • the liquid sensor 18 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 20 .
  • a suitable capacitance sensor and capacitance sensing circuit are described in U.S. Pat. No. 5,576,619, the contents of which are hereby incorporated by reference.
  • the invention has been tested using a capacitance “smart” sensor from SIE Sensors.

  • the sensor 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 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.
  • Energy is reflected either from the walls if the region is empty of liquid, or from liquid if present in the region.
  • An example of ultrasonic liquid sensor is described in U.S. Pat. No. 3,960,007, the content of which is incorporated herein by reference.
  • a commercially available ultrasonic sensor is made available by ZEVEX Inc.
