PROBLEM TO BE SOLVED: To provide chemical dosing equipment, in which the formation of blood pooling can be inhibited in a chemical-inflow void even when a puncture is made with a puncture needle in a patient in a sitting-up position and a solution is injected into the chemical-inflow void of the chemical dosing equipment, and the blood in the chemical-inflow void can be replaced with the inflow solution by means of a small quantity of the solution.SOLUTION: The subcutaneous chemical dosing equipment 1 includes: a dosing equipment body having a depressed part for forming the chemical-inflow void 23 and a discharge port 5 and a sealing member 4 which seals an opening of the depressed part of the dosing equipment body, and allows a chemical dosing needle to make a puncture in the chemical-inflow void 23. The dosing equipment body has a chemical flow passage 7 which allows the discharge port to communicate with the chemical-inflow void. The chemical flow passage has a distribution port 71 which is provided in a position opposite to the discharge port with respect to the chemical-inflow void, and communicates with the chemical-inflow void.COPYRIGHT: (C)2013,JPO&INPIT【課題】患者が上体を起こした状態にて、穿刺針を穿刺し、薬液注入具の薬液流入空間に液体を注入しても、薬液流入空間内の血液滞留部の形成がなく、少ない量の液体にて、薬液流入空間内の血液を流入液体と置換できる薬液注入具を提供する。【解決手段】皮下埋め込み型薬液注入具1は、薬液流入空間23を形成する凹部と、排出ポート5とを有する注入具本体と、注入具本体の凹部の開口部を封止するとともに薬液注入用針の薬液流入空間23への刺入が可能なシール部材4とを備える。注入具本体は、排出ポートと薬液流入空間とを連通する薬液流路7を備え、薬液流路は、薬液流入空間に対して排出ポートと向かい合う位置に設けられた薬液流入空間と連通する流通口71を備えている。【選択図】図7
