Urination autonomous by modulating in abdominal pressure intravesical pressure at the time of starting urination is possible and can be designed in various intravesical pressure at which urinary incontinence can be prevented, opening, closing, high accuracy and stability It is possible to prevent contamination and infection by a secure configuration and materials simple structure control of urination is ensured it is possible to obtain a reliable occlusion, by the opening, it can be installed in a patient of both men and women, to improve the QOL of patients to provide urination control device of the possible. An upstream restraining member having a through hole, and a control member disposed downstream of the upstream restraining member within the conduit, the conduit within the conduit to be inserted in the urethra, is provided on the upstream side of the conduit and a downstream restraining member disposed on the downstream side of the control member, provided to the inquiry to each other by magnetic force and the control member and the upper stopper member, the control member, upstream restraining member in the absence of pressure applied to the upstream side at least and closing the liquid passage of the upper restraining member is in contact with the magnetic force on the opening of the through hole of the downstream restraining member is made is configured to liquid passage can be in a state of locked control member. [Selection] Figure Figure 1排尿を開始する際の膀胱内圧を腹圧で調節することによる自律的な排尿が可能で、尿失禁が防止でき、開放、閉塞する際の膀胱内圧を様々に設計でき、安定性及び高い精度を得ることができ、確実な閉塞、開放によって排尿の制御が確保され簡易な構造と安全な構成材料によって感染や汚染を防ぐことができ、男女双方の患者に設置でき、患者のQOLを向上させることのできる排尿制御装置を提供する。尿道内に挿入する導管と、この導管内の上流側に設けられており貫通孔を有する上流制止部材と、導管内でその上流制止部材よりも下流側に設けられる制御部材と、導管内でその制御部材よりも下流側に設けられる下流制止部材とを備え、上流制止部材と制御部材とは磁力によって互いに引き合い可能に設けられ、制御部材は、少なくとも上流側にかかる水圧が無い状態では上流制止部材の貫通孔の開口に磁力によって当接して上流制止部材の通液を閉塞し、下流制止部材は、制御部材を係止した状態では通液が可能であるよう構成されてなる。【選択図】図1
