DESCRIPTION:
BRIEF SUMMARY
This invention relates to urine sampling devices.
It is an object of this invention to provide a urine sampling device which is particularly useful in collecting urine samples from female patients but which may also be used for collecting urine samples from infirm and young patients.
One example of a known urine collection device is that disclosed in U.S. Pat. No. 5,146,637. This comprises a body having sidewalls and a bottom which is suspended across the entire width of the toilet bowl by three arms which extend over the rim of the toilet bowl. The bottom of the device if funnelled to an outlet. A support is provided below the outlet to support the upper rim of a collecting cup. In use, urine is received in the collection device, and this is funnelled through the outlet and into a collecting cup supported below the outlet.
An alternative urine collection device is disclosed in U.S. Pat. No. 5,060,317. This comprises a bracket mounted to the rim of the toilet bowl and including a hole for receiving a sample cup. In use, the sample cup is supported within the toilet bowl by the bracket, and collects urine. A handle is then used to remove the sample cup from the bracket. U.S. Pat. No. 4,137,573 also discloses the use of a bracket mounted to the toilet bowl for receiving a sample cup to collect urine.
According to the present invention a urine sampling device comprises an elongated trough member having a width substantially greater than its depth to define a generally pan-like trough, the trough member being fitted at a first end thereof with an attachment formation arranged to engage the rim of a toilet bowl such that, in use, the trough member extends at an angle below the horizontal such that the trough is orientated to intercept a stream of urine being passed by a patient seated on the bowl, and to minimise splashing of such urine onto the patient, the device further including a urine sample collecting arrangement disposed at or towards the extremity of the trough remote from the first end thereof, and having an overflow lip through which surplus urine not collected by the collecting arrangement is discharged into the toilet bowl.
Thus the collecting arrangement may comprise a hollow spigot extending downwardly from the trough member to define a passage and onto which hollow spigot a pathology sample bottle may temporarily be mounted in use.
In another form of the invention the collecting arrangement may comprise a liner for the sampling device. The liner in issue may be shaped to be mounted in the trough-shaped sampling, device and be adapted to be lifted from the sampling device to contain the urine sample for analysis. Preferably the liner defines a well region adapted in use to be received in an appropriately shaped and located depression in or passage through the trough.
The liner may be made from any suitable polymeric material.
In a preferred arrangement according to this form of the invention there is provided a pack of liners of the type in issue which may be placed in the trough-shaped sampling device to be individually peeled from the pack as and when required.
DETAILED DESCRIPTION OF INVENTION
In the accompanying drawings of non-limiting, examples which serve to illustrate the invention:
FIG. 1 is a cross-sectional side view through a toilet bowl, with seat and cover onto which bowl the urine sampling device of the invention is shown to be fitted;
FIG. 2 is a schematic perspective view of a first embodiment of the urine sampling device of the invention; and
FIG. 3 is a schematic perspective view of an alternative embodiment of the invention.
The same reference numerals are used to indicate corresponding components in the accompanying drawings.
In the drawings a trough-shaped urine sampling device 1 is shown to be fitted to the rim of a toilet bowl 2 [indicated in dotted lines in FIG. 3 at 2] by means of a clip formation 3 forming part of the sampling device. The trough and clip formation are preferably so shaped as to allow it to be mounted so that the trough extends at an angle of more or
