Technical Field
The utility model belongs to the field of medical equipment, especially, relate to blood coagulation monitoring devices field for hemodialysis pipe.
Background
Anticoagulant therapy is usually carried out by using anticoagulants such as heparin or low molecular heparin and the like in hemodialysis to avoid the occurrence of extracorporeal circulation coagulation, but when a patient has bleeding or high-risk bleeding tendency, heparin-free dialysis is required to avoid the occurrence and aggravation of bleeding; the main complication of heparin-free dialysis is blood coagulation, and in order to ensure the successful performance of heparin-free dialysis and prevent and reduce the blood coagulation of venous kettles, the traditional method is to regularly wash an extracorporeal circulation pipeline and a dialyzer with physiological saline during treatment and observe whether the blood coagulation of the dialyzer and the arterial and venous kettles of the pipeline, particularly the venous kettles, occurs or not. The venous pot is positioned in a venous pot clamp of the dialysis machine for air detection, can not be taken out at will for kneading, is not beneficial to observation, and can not be effectively treated due to the individual difference of vision and experience of medical personnel because the smaller blood clots in the hemodialysis tube are lack of accurate judgment, so that the whole blood coagulation of a hemodialyzer and a pipeline is caused, a patient needs to finish treatment in advance, the dialysis is insufficient, and the pain and the economic burden of the patient are increased; at the same time, the massive loss of blood aggravates anemia of the patient; ultrafiltration dehydration can not reach the standard in dialysis, and the water load of patients is too heavy, so that complications such as acute pulmonary edema and the like are easy to occur, the treatment effect and the living quality of the patients are seriously influenced, and the working efficiency of medical personnel is reduced.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to solve the above problems and to provide a blood coagulation monitoring device for hemodialysis.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
