Job Opportunity - Nottingham (UK)

2008-09-18 Thread Dean Gerard (Medical Physics)
The following vacancy has just been posted on the UK NHS Jobs website at
-

http://www.jobs.nhs.uk/cgi-bin/vacdetails.cgi?selection=912097352

where a detailed Job Description and Application Form are available.

(Closing date for applications is 14th October)





Nottingham University Hospitals NHS Trust was formed in 2006 by the
merger of the city's two major teaching hospitals, Nottingham City
Hospital and the Queens Medical Centre. The Clinical Engineering service
at NUH is one of the largest in the country, (employing approximately
90wte engineering, scientific, technical and administrative staff). It
provides a comprehensive range of medical equipment management and
development services to the Trust. The Department also has collaborative
links with the University of Nottingham 

An exciting vacancy has arisen for a Consultant Clinical Engineer to
support the activities of the Department and the wider Trust. This is a
unique opportunity to not only play a key role in the delivery of
operational clinical engineering services to support patient care, but
also to be instrumental in the development of safe and compliant novel
devices and in supporting clinical research employing medical technology


The post-holder will need to have extensive knowledge and practical
experience in the application of technology in medical practice. They
will also need sound knowledge of the regulatory environment and
CE-marking processes in general and with regard to medical devices in
particular. Ideally, they should be proficient in the application of
technical standards, risk management, project management, implementation
of quality systems (including ISO-900 and 13485), and in the management
of design, evaluation and testing for safety and EMC. Engineering design
and production experience would be valuable. 

Candidates ought to be HPC registered (or eligible for registration).
The role will require Chartered Engineer status and substantial
post-registration work experience in clinical engineering in a
healthcare setting. Candidates with alternative but equivalent relevant
industrial training and experience would be considered and are
encouraged to apply. 

The postholder may be expected to work at both City Hospital and Queens
Medical Centre campuses. 

To discuss details of the post further, please contact Dr. Daniel Clark
or Ged Dean on 0115-962-7646.

RE: Another Cancer Scare?

Is it really only milliseconds?  When my phone is in my desk drawer, or jacket
pocket on the back of my chair, I am aware that it is periodically active
because of interference it generates on the speakers of my PC. These bursts of
audible interference are brief - but measurable in seconds rather than
milliseconds.

RE: EMC in the news: RFID Medical

2008-06-27 Thread Dean Gerard (Medical Physics)
  

Whilst I've seen the original article (Journal of the American Medical
Association), unfortunately I can't circulate it without breaking our
subscription license agreement.

The investigation was apparently commissioned by the Dutch Ministry of Health. 

Standard they refer to is - 

American National Standard Recommended Practice for On-site Ad Hoc Test Method
for Estimating Radiated Electromagnetic Immunity of Medical Devices to
Specific Radio-frequency Transmitters (Standard C63.18). (AAMI:/ IEEE; 1997).

(not a rigorous EMC product test standard - but rather a suggested basic
methodology for equipment users to investigate possible EMI in a consistent
way)


The project was apparently driven by the search for a system to monitor blood
products, which influenced their choice of RFID systems to test, as follows -

The selection of 2 RFID systems tested in this study was based on 3
characteristics: (1) the systems needed to comply with RFID standards set by
the European Telecommunications Standards Institute; (2) radio frequencies
needed to fall within the most common internationally used RFID frequency
bands and (3) performance needed to fulfill the operational requirements of
the project including availability of temperature sensitive RFID tags,
low-cost tags suitable for disposable materials, contemporary integration with
the local communications network, and location accuracy within a health care
facility.

Tests were performed in a 1-patient room, free of reflective objects, based
upon methodology in the standard above.

FW: EMC in the news: RFID Medical

2008-06-27 Thread Dean Gerard (Medical Physics)


Just nominal power outputs and separation distances between interfering and
susceptible equipment. 

Output info given is - 
 The passive RFID system selected for this study (OBID, Feig Electronic,
Weilburg, Germany) had an 868-MHz reader (2-4 W). The active RFID system

(Eureka RFID, Avonwood, England) had a 125-kHz reader (68_10E-3 µT at 1m)
that forces tags to transmit in its proximity. The active RFID tag had an
operational frequency of 868 MHz at 2 µW

Interference effects were provoked at separation distances ranging from 5 -
600cm, depending upon equipment affected.

RE: Use of ground fault detectors in hospitals

2008-06-09 Thread Dean Gerard (Medical Physics)
Pat -
 
Relevant document is IEC-60364-7-710 Electrical Installations of Buildings -
Medical Locations, (which in the UK have been adopted under guidance notes
subsidiary to the IEE Wiring 'Regulations').
 
Use of RCDs is restricted in medical environments, precisely because of
nuisance tripping to critical equipment - where 'nuisance ' tripping could
have serious if not fatal consequences for the patient. 
 
Use of RCDs in 'Group-2' medical locations (such as operating theatres) is
restricted to particular specified circuits (such as those for X-ray units or
plant rated 5kVA) -Otherwise they should not be used.  
 
(I've no idea what the practice is in Hong Kong).

Subject: Use of ground fault detectors in hospitals



Hi listmembers: 

We have a customer in Hong Kong who is reporting problems using their
equipment in an operating room.  Specifically, the GFI/RCCB/RCD (ground fault
detector) installed in the operating room trips, shutting off power to the
system.  After resetting the GFI, the equipment can be started successfully. 

My question concerns the use of GFIs in operating rooms.  This sounds unusual
to me, and I'd think the GFI would have to meet many of the same requirements
that medical equipment needs to meet (e.g., IEC60601-1 approval).  Is anyone
familiar with either requirements or prohibitions on the use of GFIs in an
operating room?
