A disposable bedpan system using an improved disposal unit and self-supporting bedpans.

A system using totally disposable self-supporting bedpans requiring no carrier was examined in use in two hospitals. The bedpans and their contents were disposed of by destruction and flushing to waste carried out in a modified Haigh Sluicemaster disposal unit. This incorporates a positively closing and locking lid with refinements to avoid the lid slamming and has effective safety devices. The new bedpans and the improved disposal units reduce the risk of transfer and dispersal of pathogenic organisms to an acceptable level in ward and sluice room.

Bacteriological hazards of disposable bedpan systems.

A system using disposable papier maché bedpans and urinals in hospital has advantages of ease of handling for the nurse and cleanliness for the patient. Disposal of the bedpans and their contents is by destruction and flushing to waste. Some bacteriological hazards of this process in the Haigh Sluicemaster and J.M.L. Clinimatic machines are assessed, particularly the dispersal of the contents in spray and aerosol during opening, closing, and running the machines. Various safety devices were tested and some deficiencies are discussed.A major defect in the system is the need at present for a bedpan carrier or support which is not disposable and requires cleaning and disinfection. Minor problems include ordering and storing bulky items, possibly the texture of the bedpans themselves, and perhaps the effect of the bulk of paper discharged into the sewage system. At present the system seems unsuitable for use in infectious disease hospitals and has some deficiencies in use in general wards. The improvements suggested would greatly increase its acceptability which should then be completely re-assessed. To this end the examination of improved models using totally disposable bedpans is proceeding.

Use of the 'Analmatic clinical system' in the microbiological assay of vitamin B 12 and folic acid in serum.

The routine estimation of large numbers of serum folic acid and vitamin B(12) levels using the Baird and Tatlock(1) Analmatic clinical system is described and the method evaluated.Precision, accuracy, and carryover are shown to be at acceptable levels, and the advantages and disadvantages of the use of the system are discussed. It is considered that with some modifications the Analmatic system offers a reliable and labour-saving method of carrying out considerable numbers of routine microbiological assays.

Residual formaldehyde after low-temperature steam and formaldehyde sterilization.

The levels of formaldehyde remaining in various articles have been estimated immediately after a low-temperature steam and formaldehyde sterilizing process and after various periods of aeration. These levels have been compared with the levels of ethylene oxide remaining after exposure to an ethylene oxide sterilizing process. In rubber and polythene and a plastic, formaldehyde levels are low and slowly fall even further. Ethylene oxide levels are relatively much higher even after seven days' aeration. It is not considered that the residual levels of formaldehyde in rubber, polythene, and a plastic should constitute a danger. Residual levels of formaldehyde in fabrics and paper are higher but this may be of value by giving a self-disinfecting action on storage.
