DESCRIPTION:

BRIEF SUMMARY
This invention relates to a device to facilitate self-catheterisation in women.
Persons who have a bladder or like sac which has become atonic, either spontaneously or iatrogenically, have to relieve the bladder by the insertion of a catheter through the urethra and into the bladder. This presents no problem for men but women, especially the elderly, arthritic or handicapped, experience some difficulty in locating the entrance to the urethra and in then inserting the catheter.
According to the present invention there is provided a device to facilitate self catheterisation in women, wherein a body portion for insertion in the vagina has or is associated with a passage way, one end of which is intended to engage against the mouth of the urethra and the other end of which is intended to receive the leading end of a catheter, and wherein the device incorporates a handle portion and a locating member which lies substantially at right angles to the body portion and is intended to engage against the outside of the vagina thereby to locate said one end of the passageway.
In the use of this device, the body portion is inserted into the vagina until the locating member abuts the outside of the vagina, whereby one end of the passageway is correctly located in relation to the mouth of the urethra. A catheter is then inserted into the passageway, the position of the other end of which can be readily determined, and then through the urethra to empty the bladder.
While the present device will generally be made in a relatively small number of standard sizes, both as regards width of the body portion and distance between the locating member and one end of the passageway, there may be occasions when the device has to be made to particular requirements, especially as regards the location of the said one end of the passageway, and, in any case, the distance between the locating member and the mouth of the urethra has to be measured. Accordingly, a subsidiary aspect of the present invention provides a locating and measuring device, comprising two body portions for insertion in a vagina, the leading ends of the body portions being hinged or elastically joined together, each body portion being connected at its other end to a locating member which lies substantially at right angles to the body portion, which is intended to engage against the outside of the vagina and which has a handle portion.
In the use of this latter device, the body portion is inserted into the vagina by the surgeon who then inserts a catheter into the urethra. The two handle portions are gripped by the surgeon to cause the body portions to clamp about the catheter, which together with the device is withdrawn and the distance between the locating members and the urethra is noted, this being the required distance between the locating member and the passageway in the final self-catheterisation device.
In order to enable the invention to be more readily understood, reference will now be made to the accompanying drawings, which illustrate diagrammatically and by way of example an embodiment thereof and in which:
FIG. 1 is a perspective view of a device for facilitating self-catheterisation,
FIG. 2 is a side view of the device with a catheter in position,
FIG. 3 is a side view of another form of the device for facilitating self-catheterisation,
FIG. 4 is a perspective view of the device shown in FIG. 3, and
FIG. 5 is a perspective view of a locating device.
Referring now to FIGS. 1 and 2 of the drawings, there is shown a device to facilitate self-catherisation in women for emptying the bladder. The device comprises a body portion 1, a locating member 2 substantially at right angles to the body portion and a handle portion 3 formed by curving the end of the locating member. The body member 1 is formed with a passageway 4 which extends in the form of a tube 5 below the body member.
In the use of the device, the body portion 1 is inserted into the vagina until the locating member 2 abuts against the outside of the vagina. In this position, the distance d is such that
