Abstract

An elongate tubular probe (1) is partially surrounded by an inflatable balloon (2) which is connected at the distal, exterior end of the probe to an inflating valve (4) via a conduit (5) attached to the probe body. The balloon is formed with a spinning-top shaped configuration corresponding to that of the prostatic chamber. The lower end (3) of the balloon includes a portion of increased wall thickness, extending around its entire circumference. The increased resistance to inflation of this portion defines the top-shaped configuration of the balloon on inflation. ADVANTAGE - Avoids risk of post-operative haemorrhage and infection of prostate gland.

Description

SONDE URINAIRE A BALLONNET HEMOSTATIQUE
La présente invention est une sonde urinaire destinée à éviter un des inconvénients post-opératoires principaux de la chirurgie de la prostate qu'est lthémorragie post-opératoire.HEMOSTATIC BALLOON URINARY PROBE
The present invention is a urinary catheter intended to avoid one of the main post-operative disadvantages of prostate surgery, which is post-operative hemorrhage.

Les sondes existantes (vu la forme du ballonnet) ne permettent pas en effet de juguler l'hemorragie de manière satisfaisante au niveau du fond de la loge prostatique, cette loge très vascularisée ayant la forme d'un coquetier. The existing probes (given the shape of the balloon) do not in fact make it possible to contain the hemorrhage satisfactorily at the level of the bottom of the prostatic compartment, this very vascularized compartment having the shape of an egg cup.

La présente invention sera mieux comprise à la lecture de la description qui va suivre, en référence au dessin annexé, dans lequel
- la figure 1 représente une sonde urinaire classique en place dans la loge prostatique;
- la figure 2 représente la sonde selon la présente invention, mise en place dans la loge prostatique; et
- la figure 3 représente vue en coupe la sonde selon la présente invention.The present invention will be better understood on reading the description which follows, with reference to the appended drawing, in which
- Figure 1 shows a conventional urinary catheter in place in the prostate gland;
- Figure 2 shows the probe according to the present invention, placed in the prostate gland; and
- Figure 3 shows a sectional view of the probe according to the present invention.

Le ballonnet de la sonde proposée est caractérisé par sa forme de toupie (2) gonflable, épousant la totalité de la paroi de la loge, y compris le fond qui se trouve ainsi comprimé, ce qui empêche toute hémorragie. The balloon of the proposed probe is characterized by its shape of an inflatable top (2), conforming to the entire wall of the compartment, including the bottom which is thus compressed, which prevents any bleeding.

Il est adaptable à toute sonde urinaire existante. A cet effet, le ballonnet (2) sera positionné sur la sonde proprement dite (1) de manière à ce que le système une fois en position, c'est à dire le ballonnet (2) situé dans la loge prostatique, ltextrémité proximale (1) de la sonde se trouve nettement dans la vessie. Le système monobloc sonde-ballon grâce à son extrémité dépassante et endovésicale sert à drainer les urines et, grâce à son ballonnet il assure l'hemostase de la loge prostatique évidée après opération. It is adaptable to any existing urinary catheter. For this purpose, the balloon (2) will be positioned on the probe itself (1) so that the system once in position, i.e. the balloon (2) located in the prostate gland, the proximal end ( 1) the probe is clearly in the bladder. The monobloc probe-balloon system thanks to its protruding and endovesical end is used to drain the urine and, thanks to its balloon it ensures the hemostasis of the prostatic compartment hollowed out after operation.

Il est caractérisé par le fait qu'il est réalisé en matière synthétique très souple atraumatique (identique à celle de la sonde urinaire) faisant corps avec la sonde (1). La forme de toupie du ballonnet sera obtenue par tout moyen approprié. Selon un mode de réalisation préférentiel la paroi sera plus épaisse sur toute la circonférence en bas de la toupie (3) afin d'obtenir un gonflement moins important à cet endroit qu'en haut de ladite toupie (2). It is characterized by the fact that it is made of very flexible atraumatic synthetic material (identical to that of the urinary catheter) integrating with the catheter (1). The top shape of the balloon will be obtained by any suitable means. According to a preferred embodiment, the wall will be thicker over the entire circumference at the bottom of the router (3) in order to obtain less swelling at this location than at the top of said router (2).

Comme pour tout dispositif analogue existant, le gonflage s'obtint de ltextérieur à l'aide d'une valve (4) dont le canal (5) est situé dans la paroi de la sonde. As with any existing analog device, inflation is obtained from the inside using a valve (4), the channel (5) of which is located in the wall of the probe.

AVANTAGES DE LA PRESENTE INVENTION
1 ) Eviter 1 'hémorragie post-opératoire souvent importante nécessitant parfois une reprise chirurgicale pour 1 'hémostase dans les heures qui suivent la première intervention.ADVANTAGES OF THIS INVENTION
1) Avoid the often significant post-operative haemorrhage, sometimes requiring resumption of surgery for haemostasis in the hours following the first intervention.

2 ) Eviter le recours aux transfusions sanguines (intérêt particulier du fait du Sida, de l'Hépatite virale, éventuellement de réticences d'ordre religieux). 2) Avoid the use of blood transfusions (special interest due to AIDS, viral Hepatitis, possibly religious reluctance).

3 ) Eviter toute infection rétrograde grâce à la forme du ballonnet qui empêchera toute progression microbienne locale vers la loge prostatique et de là vers la vessie. 3) Avoid any retrograde infection thanks to the shape of the balloon which will prevent any local microbial progression towards the prostate gland and from there towards the bladder.

4 ) Pour tout ce qui précède, la durée d'hospitalisation sera notablement raccourcie avec tous les avantages évidents que cela comporte. 4) For all of the above, the length of hospital stay will be significantly shortened with all the obvious advantages that this entails.

Claims

CLAIM

1) Urinary probe with hemostatic balloon constituted by a probe proper (1) around which an inflatable balloon (2) is incorporated, said balloon (2) being connected to the distal and external end of the probe by an inflation valve (4) by means of a channel (5) incorporated in the wall of the probe, probe characterized in that the inflatable balloon (2) has the shape of a top designed so as to follow the whole of the wall of the prostate gland hollowed out after operation and by the fact that it is positioned on the probe itself (1) so that the proximal end of the latter is largely protruding and able to drain urine from the bladder .

2) urinary catheter according to claim 1), characterized in that the balloon (2) has in its lower part (3) a thickness reinforcement over its entire circumference so as to achieve after inflation the balloon in the shape of a spinning top.
