Embodiment Construction

[0021] exist Figure 3-6 In , for the sake of clarity, the cross-sections are not shown with conventional dashed lines.

[0022] refer to Figure 1-6 , with a three-way bladder catheter (not shown), fluid flow switching means for catheterization is indicated at 100 . In these figures, the achievable fluid flows are indicated by dashed lines and arrows indicate their direction. The fluid flow switching device 100 for catheterization with a three-way bladder catheter includes:

[0023] - housing 7;

[0024] - first, second, third and fourth openings 11, 12, 13, 14 in the housing 7;

[0025] - first, second and third distal hydraulic conduits 1 , 2, 3 starting from the first, second and third openings 11 , 12, 13 respectively;

[0026] - a switchgear 20 designed to engage with the housing so as to communicate the first opening 11 with the third opening 13 in a first operating configuration and to communicate the second opening 12 with the fourth opening 14 in a second operat...

Abstract

Flow switching device for catheterization with a three way catheter comprising: - a housing (7) having four opening (11, 12, 13, 14); - a first, second and third distal hydraulic conduit (1, 2, 3), originating at the first, second and third opening (11, 12, 13), respectively; - switching means 20 engaging with the housing from obtaining a first operative configuration, wherein the first and thirdopening (11,13) are in communication; a second operative configuration, wherein the second and fourth opening (12, 14) are in communication; a third operative configuration, wherein the first and second opening (11, 12) are in communication; a fourth operative configuration wherein the second and third opening (12,13) are in communication; and - hydraulic bifurcation (17) comprising: a respectiveproximal hydraulic branch (6) originating from said fourth opening (14), a fourth and fifth distal hydraulic conduit (4, 5) originating distally from said proximal hydraulic branch and which are fluiddynamically communicating with respect to each other.

Description

technical field [0001] The present invention relates to the field of medical devices that can be used in healthcare procedures where it is necessary to manage the flow of fluid (preferably liquids) in a patient, especially in urology, more particularly when a three-way bladder catheter is required. Background technique [0002] Three-way bladder catheters are used in post-operative treatment of bladder or prostate surgery to drain bleeding from the bladder and / or prostate respectively. It has three lumen branches at the first end in three different ways. The second end of the catheter is provided with an inflatable balloon representing the end of the second passage, while the first and third passages are open at both ends of the catheter. The second end of the catheter is inserted into the urethra into the bladder and held in place, delivering saline through the catheter's second channel into the balloon. A continuous flow of urine and blood exits the patient's body from t...
