new tubes for old hospitals

Hospital architecture has to constantly evolve with medical technology. It has been said that a hospital is already outdated by the time it is built. New imaging techniques mean new radiological suites, laproscopic surgery calls for different operating room spaces, and green star ratings requires modifications in temperature control, water management and waste disposal. Existing pneumatic tube systems are updated, and installed, adapting to the needs of the hospital.

New wards in hospitals are being installed with pneumatic tubes, such as at Vista Health System, in Waukegan, Illinois (USA), where a new pneumatic tube system in the Progressive Care Unit delivers "supplies and medical documents directly to the nurses station". In Kovai Medical Centre and Hospital, in Coimbatore, Tamil Nadu (India), a new pneumatic tube system not only "helped reduce medication errors, mix-up of laboratory samples, sample misplacement" but also supposedly "improved the working relationship amongst staff in the clinical support areas". Since the tubes have also led to a "silent" pharmacy and laboratory, with minimal interaction between staff and patient assistants (moving in and out in the street shoes), one can't help but wonder what other effects the technology may be having on working relationships in the hospital.

This photo, from Flikr, shows a steamfitter and foreman for SwissLog checking pneumatic tube piping for dents. It is part of a series of photos taken by Marc Barnes documenting the installation of pneumatic pipes and other construction work at the Fort Belvoir Community Hospital Oaks Pavilion, in Fort Belvoir, Virginia (USA).

homely tubes

Pneumatic tube systems are used in hospitals, supermarkets, banks and pharmacies. But what about our own homes?

A UK-based project called Foodtubes, which promises to revolutionalise food transportation via pneumatic/vacuum technology, has recently led to all sorts of incredulous outcries and postulations by techie and environmental bloggers embracing and ridiculing the idea. Someone who has commented on the grist blog post about this issue argues that it is a waste to use Foodtube technology at the organisational level, but rather it should be taken into our own homes:

"I don't know about replacing deliveries to stores... trucks are awfully efficient for that! Make them electric, and they'd be hard to beat. On the other hand, pneumatic tubes could provide efficient delivery to individual homes, eliminating the need for people to go to the store. With modern barcode or RFID systems, the packages could be routed to the correct house easily enough. Some things might not do too well - I wouldn't want to cram a 20-pound watermelon into a 6-inch tube - but for most staples it would work quite well"

It isn't the first time that pneumatic tube technology has been considered for home usage. Remember that great Heineken ad from a few months ago? There is also the home elevator, as well as centralised home vacuum cleaning units. My dad remembers one of these units being installed in his parents' new home in the 1980s. It seems that home-based pneumatic tube technology is either something from the past, or the projected Jetsonian future, but is it for us right now?
