Title
(EN) CATHETER FOR EXTRACTING HUMORS INSIDE CRANIUM CAVITY
(FR) CATHETER POUR L'EXTRACTION DES HUMEURS DE LA CAVITE CRANIENNE
Abstract
(EN)
A catheter (10) for extracting cranial cavity humors comprising an elongated tube portion (12), a head portion (13) and a plurality of holes (14) formed at the tube portion (12) near said head portion (13). The tube portion (12) is formed with an extraction duct (12a) for extraction of a humor in the cranial cavity, and an injection duct (12b) for injection of a thrombus dissolving medicine from the exterior of the cranial cavity into the interior of the cranial cavity. The head portion (13) is formed with a through-hole (13a). The injection duct (12b) is fitted with an injection tube (16) extending to the outside of the tube portion (12) to form a connecting portion. The connecting portion of the injection tube (16) and the injection duct (12b) is sealingly fixed by a first connecting member (17). The catheter (10) of the present invention can extract humors in the cranial cavity as well as make the injection of the thrombus dissolving medicine easier while maintaining inner-brain pressure. The catheter (10) also eliminates the risks of infection by preventing reflow of humors including a thrombus in the catheter (10).
(FR)
L'invention concerne un cathéter (10) destiné à extraire les humeurs de la cavité crânienne et comprenant une partie tubulaire allongée (12), une partie tête (13) et une pluralité de trous (14) formés au niveau de la partie tubulaire (12), près de la partie tête (13). La partie tubulaire (12) est constituée d'un conduit d'extraction (12a), par lequel on extrait une humeur de la cavité crânienne, et d'un conduit d'injection (12b), par lequel on injecte, dans la cavité crânienne, un médicament dissolvant un thrombus. La partie tête (13) comporte un trou traversant (13a). Le conduit d'injection (12b) est pourvu d'un tube d'injection (16) s'étendant à l'extérieur de la partie tubulaire (12) et formant une partie de raccordement. La partie de raccordement du tube d'injection (16) et du conduit d'injection (12a) est fixée hermétiquement par un premier élément de raccordement (17). Le cathéter (10) de cette invention peut servir à extraire des humeurs de la cavité crânienne et à effectuer plus facilement des injections de médicament dissolvant un thrombus tout en maintenant une pression cérébrale interne. Ce cathéter (10) permet d'éliminer les risques d'infection en empêchant le refoulement des humeurs comprenant un thrombus dans le cathéter (10).
