Abstract
The invention relates to a system for monitoring a patient's physiological signals and associated devices. Signals are transmitted wirelessly between the battery powered data acquisition subsystem (which also stores the data for later transmission if the wireless link is unavailable) and the host system which has a standard Microsoft Windows Graphical User Interface. The system also allows transmission of control signals from the host system to the data acquisition sub-system. Bluetooth technology, utilised for the digital transmission and encryption of data, will also form the foundation for the automatic detection of host proposed for the system. It has application in ambulatory or static studies in hospitals, clinics or elsewhere, providing wireless connectivity of medical devices allowing systems to be configured and located to suit patients and care staff. Embodiments detail a urine flowmeter, a urodynamics system, a gastro-intestinal motility system and an ano-rectal manometry system.
Description
DESCRIPTION
Wireless Physiological Monitoring System The invention relates to a system for monitoring a patient's physiological signals and the signals from associated devices. The signals are transmitted by wireless means between the data acquisition subsystem and the host system which has a Graphical User Interface (GUI) The system also allows for control signals to be sent from the host system to the data acquisition sub-system.
Similar wired systems are well known but suffer from the disadvantages that: À the equipment is hard wired so there are often many cables which represent a physical and electrical hazard cables become contaminated as the area is often not clean the whole equipment has to be located very near the patient À the equipment is often bulky and space is often limited (em. in operating theatres, x-ray rooms) À several people are needed to administer the equipment for the study so the patient has an "audience" for often intimate examinations which leads to stress induced erroneous results À all those involved need to be in close proximity to the patient so are, for example exposed to x-rays, contamination etc Existing wireless systems suffer from the following problems: À transmission can be unreliable (especially for infra-red methods) À data is not secure À signals are prone to interference with consequent loss of data À the transmission system can cause interference with other equipment (e.g. in operating theatres) Current systems, hard wired and wireless, static and ambulatory, suffer from lacking user-friendliness with many settings to be made, cables to connect and using uniquely configured software instead of common software formats with which the user would be familiar. l An object of this invention is to overcome the above listed problems.
Unlike some existing developments, which are only designed for "care in the community", with data logged over a long period of time (data delay / loss being less critical) this invention mill also allow use for specific hospital applications and give real time monitoring. It provides wireless connectivity of medical devices allowing systems to be configured and located to suit patients and care staff rather than being dictated by cable lengths. The data acquisition unit derives its power from batteries. It |
interfaces to other ancilliary devices as required.. This invention includes a standard Microsoft Windows Graphic User Interface to further facilitate easy use.
Accordingly, this invention utilises new communications technology applied to ambulatory or static studies with application in hospitals and r.linics although the principles can used elsewhere.
The attached figures 1 to 4 show possible configurations of the invention.
FIGURE 1 shows a system diagram of the generic system. Data from the subject(4), is collected, conditioned and transmitted by the data acquisition unit (3) via wireless link(2) to the host system(l). The user(5) and host system can be located locally or remotely. Data can be transferred between patient ancilliary devices(6) also.
The following figures are three embodiments of the invention which are described with reference to the appropriate features.
FIGURE 2 shows a specific application for a urine flowmeter.
This allows the patient to pass urine into a receptacle(7) in a private cubicle with the results being observed by staff (e.g. doctor(5), nurse(8) , assistant(9)), analysed and stored remotely on the host system(1). Data is transmitted by a wireless radio link(2) and is also stored in the data acquisition sub-system(3) for later transmission if the wireless link is unavailable. The host system in this case is a Personal Computer (PC) with Graphic User Interface (GUI) which may be interfaced to other systems for onward transmission. Bluetooth technology is utilised for the digital transmission and encryption of the data. This will also form the foundation for the automatic detection of host proposed for the system of figure 4.
FIGURE 3 shows a specific application for a urodynamics system This allows the host system(l) (which may again be a PC with GUI) to be located remotely so, for example, if the patient is being studied in conjunction with a simultaneous x-ray investigation, a commonly used technique for studying urinary incontinence and obstruction, personnel(5) (8(10) can be in a safe area not exposed to x-rays yet able to see and control the study. Similar transmission methodology is used to that described for figure 2 above.
FIGURE 4 shows a specific application for a Gastro-Intestinal Motility for monitoring of patients within the laboratory or clinic (static study) and for ambulatory study over an extended period with the patient undergoing activity away from the laboratory or clinic. The Bluetooth functionality allows the ambulatory system (which is a mobile data acquisition unit(3)) to automatically detect when within range of an eligible host system(1)
l and automatically transfer data from the data acquisition subsystem to the host via the wireless link(2).
These are only three examples but the generic approach is patented utilising any wireless protocol required.
