<p>[Problem] To provide a medical-use pump capable of detecting that the tip of a needle has become dislodged from within a blood vessel (needle dislodgement), and reliably warning a health care professional. [Solution] The invention is a medical-use pump for delivering medication through an infusion tube (200) and the tip of a needle attached to the infusion tube to within a blood vessel of a patient, the medical-use pump being provided with: a drive motor (61) which delivers the medication through the infusion tube and the needle; an occlusion sensor (53) which detects occlusion pressure of the infusion tube when delivering the medication; a control unit (100) which, by way of the occlusion pressure of the infusion tube obtained from the occlusion sensor (53), in a case in which the occlusion pressure has suddenly risen by greater than or equal to a threshold, determines that the tip (197) of the needle (172) has been dislodged from within the blood vessel (198) and is positioned outside the skin; and warning means (130, 131, 132) which issue a warning by way of an instruction of the control unit if the occlusion pressure suddenly rises or suddenly falls by greater than or equal to the threshold.</p> |
