PROBLEM TO BE SOLVED: To provide a thromboprophylaxis lower leg supporter that suppresses reduction of a skin blood flow by the pressure of a wears leg part (lower leg) entire circumference to a minimum and can be worn relatively comfortably.SOLUTION: A thromboprophylaxis lower leg supporter 10 includes: a cuff part (upper end cuff part 1a, and lower end cuff part 1b) becoming an upper end and a lower end of a cylindrical knitted fabric a strong expansion and contraction part 2 avoiding a portion (blood storage opposite part 3a) opposed to the blood storage portion in a wearers calf circumference front surface from a portion (storage part 2a) corresponding to a blood storage portion of a wearers lower leg rear surface, being an upper end (upper end cuff part 1a) of a cylindrical knitted fabric and a lower end (lower end cuff part 1b) side, circulating the cylindrical knitted fabric toward a wearers lower leg front surface, and having a stretching resistance larger than the upper end cuff part 1a and a weak expansion and contraction part 3 being the blood storage opposite part 3a and having the stretching resistance lower than the upper end cuff part 1a.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 着用者の脚部(下腿)全周の圧迫による皮膚血流量の減少を最小限に抑えて、比較的快適に着用することができる血栓予防下腿用サポーターを提供する。【解決手段】 血栓予防下腿用サポーター10は、筒状編地の上端及び下端になる口ゴム部(上端口ゴム部1a、下端口ゴム部1b)と、着用者の下腿後面の貯血部分に対応する部分(貯血部2a)から、着用者の下腿最大囲前面における貯血部分に対向する部分(貯血対向部3a)を避けて、筒状編地の上端(上端口ゴム部1a)及び下端(下端口ゴム部1b)側であり、着用者の下腿前面に向けて、筒状編地を周回し、上端口ゴム部1aよりも伸縮抵抗が大きい強伸縮部2と、貯血対向部3aであり、上端口ゴム部1aよりも伸縮抵抗が小さい弱伸縮部3と、を備える。【選択図】図1
