Abstract

Device for uterine catheterisation for the purpose of performing hysterographies and insufflation of the Fallopian tubes. The invention relates to a device allowing injection, without pain and without reflux, a radiopaque liquid, antibiotics, or alternatively any other liquid, under pressure, into the uterine cavity. It consists of a tube 5, with two upper orifices 9 and 10 and a lower orifice 7, it is 45 cm long. An inflatable balloon 2 is located half a centimetre from its upper end. This balloon 2 measures 2.5 cm. It is made of elastic rubber, or alternatively any other appropriate material. 1.5 cm from the end of this balloon, a collar of plastic or other rigid or semirigid material is adhesively bonded. This collar measures at least 1.5 cm in diameter, and has the thickness of at least 4 mm. The inlet of the device and the inflation valve are situated at the lower end of the device. The device according to the invention is in particular intended for catheterisation of the isthmus of the neck of the uterus, and of the cavities.

Description

La presente invention concerne un dispositf pour cathétérisme
de l'isthme utérin féminin. Dans le but de pratiquer facile
ment et, sans douleur des hystérographies. Ainsi que toute
injection médicamenteuse à l'intérieur de la cavité utérine.The present invention relates to a device for catheterization
of the female uterine isthmus. In order to practice easy
and without pain hysterographies. As well as all
drug injection inside the uterine cavity.

Les hystérographies et insuflations tubaires sont actuelle
ment pratiquées avec des dispositifs en verre ou en métal.Tubal hysterographies and insufflations are current
practiced with glass or metal devices.

Ces techniques sont douloureuses pour la malade. Elles néces
sitent la mise en place sur le col utérin de pinces ou
pour les instruments en verre l'adjonction de moteurs à à dépression. Ces dispositfs n'offrent pas d'étanchéité de
la cavité uterine. Les produits injectés sont refoulés dans
la cavité vaginale. De ce fait les résultats sont moins
bons, incertains, et trés souvent obligent le praticien à
recommencer son examen.These techniques are painful for the patient. They need
place clamps on the cervix or
for glass instruments the addition of vacuum motors. These devices do not offer
the uterine cavity. The injected products are forced back into
the vaginal cavity. As a result, the results are less
good, uncertain, and very often require the practitioner to
repeat the exam.

La sonde selon l'invention permet de remédier à ces inconve
nients. Elle comporte en effet un ballonnet supérieur (2) qui
permet sa mise en bonne place et son étancheité à l'intérieur
de la cavité utérine. A 1 cm. % de la fin du ballonnet supé

rieure de la sonde permet l'adaptation d'une seringue. of the probe allows the adaptation of a syringe.

Selon une variante la sonde peut être de différents diamètres X La figure 1 représente en coupe le dispositf selon l'invention. According to a variant the probe can be of different diameters X FIG. 1 shows in section the device according to the invention.

Le dispositf représenté sur la figure 1 comporte un long tuyau(5) de 45 cm. de long. Le diamètre du dispositif pourra varier selon les besoins. L'extrémité supérieure(8) est fermée , l'extrémité inférieure (7) permet l'adaptation d'un embout de seringue . A cm. de l'extrémité supérieure un ballonnet (2) en caoutchouc ou toute matière synthêtl e médicale est gonflable à partir de 5cc. La longueur tu ballone () est de 2 cm. 1/2. Dégonflé ce ballonnet n'augmente le diamètrede la sonde que de imm. Le ballonnet (2) est gonflé grâce à un fin tuyau (4) passan dans l'épaisseur de la parole de la sonde, et, se raccordant à la base de la sonde à une valve (6) zanzi retour.A 1cm. et plus selon le modèle choisi, de la fin du ballonnet (2) est fixée une colerette (3) en matière plastique ou toute aut-e matière synthétique médicale, rigide ou semi rigide. Dans un autre modèle cette colerette pourra être non fixée. btépaisseur de cette colerette est de 4mm. mais poura Aetre augmenté ou diminué selon les besoins du modèle choisi. Le digère de cette colerette est de 1cm1/2, mais pourra varier selon les modèles de sonde.The device shown in Figure 1 has a long pipe (5) of 45 cm. long. The diameter of the device may vary as required. The upper end (8) is closed, the lower end (7) allows the adaptation of a syringe tip. At cm. from the upper end a rubber balloon (2) or any medical synthetic material is inflatable from 5 cc. The length of the balloon () is 2 cm. 1/2. Deflated this balloon increases the diameter of the probe only by imm. The balloon (2) is inflated by means of a thin pipe (4) passing through the thickness of the floor of the probe, and, connecting at the base of the probe to a valve (6) zanzi return. At 1cm. and more depending on the model chosen, from the end of the balloon (2) is fixed a collar (3) made of plastic or any other medical synthetic material, rigid or semi-rigid. In another model, this collar may be not fixed. bthickness of this flange is 4mm. but can be increased or decreased according to the needs of the chosen model. The digest of this collar is 1cm1 / 2, but may vary depending on the probe models.

Le modèle que nous avons éssayé comportait les dimensions suivantes: longeur de la sonde 45cm, colerette disposée et fixée à 6 cm 1/2 de l'extrémité supérieure de la sonde, diamè tre de la colerette 1c;2 épaisseur de cette colerette 4mm
Ballonnet supérieur de 2cm1/2 de long commençant à 1/2 cm de extrémité supérieure de la sonde, et se terminant à 2cm de la colerette , la carrière de cette sonde est 12. Ce mode le est le modèle idéal pour le catéthérisme des utérus.The model that we tried included the following dimensions: length of the probe 45cm, flange arranged and fixed at 6 cm 1/2 of the upper end of the probe, diameter of the flange 1c; 2 thickness of this flange 4mm
Upper balloon 2cm1 / 2 long starting at 1/2 cm from the upper end of the catheter, and ending at 2cm from the collar, the career of this catheter is 12. This mode is the ideal model for catetheresis of the uterus .

ce type de sonde pourra être fabriqué pour d'autre indications médicales, mais dans ces cas la les diamètres de sondes seront proportiennels aux ballonnet qui seront plus longset plus gonflables, les colerettes seront plus épaisses et de diamètre plus grands, il est évident que la position de ces colerettes seront différentes et en rapport du modèle choisi.this type of probe can be manufactured for other medical indications, but in these cases the diameters of probes will be proportional to the balloon which will be longer and more inflatable, the flanges will be thicker and of larger diameter, it is obvious that the position of these flanges will be different and related to the model chosen.

il peut être envisagé de fabiquer cette sonde dans toutes les charrières axistantes. it can be envisaged to manufacture this probe in all axially oriented quarries.
