Benefits of technology

The present invention relates to an aspiration system for removing liquids from the human body, particularly urine. The invention aims to address the problems of urinary management in acute and long-term care settings, where urinary catheterization is commonly used but can be uncomfortable and may lead to infections. The invention provides an improved aspiration system that can detect and remove liquid in a more efficient and comfortable way, reducing the risk of infection and improving patient outcomes. The invention includes an aspiration unit and a body interface device that can be easily attached to the body, allowing for easy and hygienic removal of urine. The technical effects of the invention include improved detection and removal of body liquid, reduced discomfort and risk of infection, and improved patient outcomes.

Problems solved by technology

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.
There is a growing problem with nosocomial infections and a high incidence of catheter-related urinary tract infections (UTIs).
However, there are obvious concerns about the possibility of electrical current leaking from the electrodes, through the conductive urine, to the skin.
Moreover, 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.
However, the design is very expensive and impractical commercially.
Any residues or moisture condensation could easily cloud the window and falsely trigger the pump to turn on.
The 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.
Moreover, the 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.

Embodiment Construction

[0012]Preferred embodiments of the invention are now described with reference to the drawings. The same reference numerals are used to depict the same or equivalent features in each embodiment.

[0013]Referring to FIG. 1, 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.

[0014]In the case of urine removal, the body interface device 14 is configured to fit at the genital region of a male or female wearer, or a surgical urosto...

Abstract

An aspiration system for removing urine from the human body comprises a disposable body interface device having a liquid collection chamber. A detachable or permanently attached non-contact liquid sensor disposed outside the liquid collection chamber detects the presence of urine within the chamber. The non-contact sensor is selected from: a capacitance sensor; an ultrasonic sensor; a piezo-resonant sensor; and a temperature sensor.

Description

FIELD OF THE INVENTION[0001]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.BACKGROUND TO THE INVENTION[0002]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...
