摘要：
A cross-shaped double sleeve drainage tube, which comprises an inner drainage tube (1), a connecting element (3), an outer catheter (21), an inner catheter (22), a support frame (23), a stopper (24), and a pressure sensor (4). The left extremity of the inner drainage tube (1) is opened while the right extremity thereof is closed. An inner drainage hole (11) is provided on the sidewall at the right extremity of the inner drainage tube (1). The connecting element (3) is used for mounting the inner drainage tube (1) into a lumen of the inner catheter (22). Both the left and right extremities of the outer catheter (21) respectively are opened. Several drainage grooves (25) are provided on the tube wall at the right extremity of the outer catheter (21). The inner catheter (22) is mounted within the outer catheter (21) via the support frame (23). Both the left and right extremities of the inner catheter (22) are opened the left extremity is connected to the tube wall of the catheter (21). A pressure monitoring channel (221), an infusion channel (222), and an outer drainage hole (26) are provided on the tube wall of the inner catheter (22). The stopper (24) comprises a plug (28) for being plugged into and blocking the opened right extremity of the inner catheter and a plugging body (29) for correspondingly blocking the right extremity part of the outer catheter (21). A gap is formed between the left end surface of the plugging body (29) and the right end surface of the outer catheter (21). The pressure sensor (4) is connected to the pressure monitoring channel (221).La présente invention concerne un tube de drainage à double manchon en forme de croix, qui comprend un tube de drainage interne (1), un élément de raccordement (3), un cathéter externe (21), un cathéter interne (22), une structure de support (23), une fermeture (24) et un capteur de pression (4).
