URINE SAMPLING DEVICE

Abstract: A urine sampling device (1) which facilitates urine sampling of female and infirm patients which is adapted to be associated with a toilet bowl (2) to collect a sample while the patient passes urine while seated on the toilet, wherein the urine sampling device (1) comprising 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 (3) by means of which the device (1) may in use be mounted in the toilet bowl (2) so that the trough member extends at a suitable angle to the horizontal so as to intercept a stream of urine being passed by a patient seated on the bowl (2), and also so as to minimise splashing of such urine onto the patient, the device (1) further including a urine sample collecting arrangement (4, 5).

Description: UR I N E S AM P L I N G D E V I C E 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. 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 by means of which the device may in use be mounted in a toilet bowl so that the trough member extends at a suitable angle to the horizontal so as to intercept a stream of urine being passed by a patient seated on the bowl, and also so as to minimise splashing of such urine onto the patient, the device further including a urine sample collecting arrangement. In one form of the invention the urine sample collecting arrangement may be disposed at or towards the extremity of the trough remote from the first end thereof. 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 THE INVENTION In the accompanying drawings of non-limiting examples which serve to illustrate the invention: Figure 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; Figure 2 is a schematic perspective view of a first embodiment of the urine sampling device of the invention; and Figure 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 Figure 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 less 30° below the horizontal into the bowl. By so mounting the device the patient may urinate normally from a seated position on the toilet bowl and the device would serve to intercept the stream of urine to direct a sample thereof towards its free end opposite the clip 3. The clip formation may be adapted snugly to engage a variety of toilet bowl configurations and may for this purpose comprise an associated spacer element which may optionally be used when required. The trough is provided towards its end opposite to the clip 3 with a hollow spigot 4 onto which spigot a pathology sample bottle 5 may be mounted as shown in Figures 1 and 2. The spigot may be tapered to be capable of receiving pathology bottles of difference internal mouth diameters or may present tapering ribs on the exterior thereof for this purpose. The free end of the trough defines an overflow lip 6 through which any surplus urine may in use be discharged into the toilet bowl. In the embodiments illustrated in Figures 1 and 2 the sampling device is preferably made by injection moulding of a polymeric material rendering it capable of being autoclaved to a temperature of 135 °C for sterilization purposes. It can also be produced from a suitable metal such as stainless steel. In the drawing of Figure 3 a pack of liners 6 is shown to be fitted on the sampling trough. The liners may be made from any pathologically acceptable polymeric sheet material. Each liner is shaped to define a well formation 8 into which a sample of urine may in use be received when a patient urinates onto the trough as described above. The necessary pathologic tests may then be conducted on the collected sample, e.g. by placing the dip-stick type diagnostic strip directly into the urine in such well. After use the urine may be discarded and the used liner may simply be stripped from the pack by means of the tab 9 provided for that purpose, thereby to expose a sterile new liner and hence rendering the device ready for re-use without the need to sterilise it in other ways. Clearly many variations of the invention may be devised without thereby departing from the spirit of the invention. Thus the pack of liners may be kept in a separate dispenser from which individual liners may be dispensed when required and placed in the sampling device as and when required.

Claims: CLAIMS: 1. A urine sampling device comprising 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 by means of which the device may in use be mounted in a toilet bowl so that the trough member extends at a suitable angle to the horizontal so as to intercept a stream of urine being passed by a patient seated on the bowl, and also so as to minimise splashing of such urine onto the patient, the device further including a urine sample collecting arrangement. 2. The device according to claim 1 wherein the urine sample collecting arrangement is disposed at or towards the extremity of the trough remote from the first end thereof. 3. The device according to claim 2 wherein the collecting arrangement comprises 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. 4. The device according to claim 2 wherein the urine collecting arrangement comprises a liner for the sampling device. 5. The device according to claim 4 wherein the liner is shaped to be capable of being mounted in the trough-shaped sampling device and adapted to be lifted from the sampling device to contain the urine sample for analysis. 6. The device according to claim 4 wherein 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. 7. The device of claim 4 wherein the liner is made from any suitable polymeric material. 8. The device of claim 8 wherein 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. 9. A urine sampling device substantially as herein described with reference to any one of the accompanying drawings.
