Description

Technical Field

[0001] The utility model relates to the technical field of blood pipeline observation devices, in particular to a blood pipeline observation device. Background Art

[0002] In hemodialysis treatment, there are many risk factors that can cause blood coagulation in the tubes. Examples of risk factors include: some patients' own coagulation dysfunction limits the choice of anticoagulants, some patients have high hemoglobin concentrations, blood transfusions or fat emulsions are given during dialysis, the tubes are blocked / the patient's condition causes restlessness and leads to insufficient blood flow, the machine alarm causes repeated blood pump stoppages, the patient's own hypercoagulable state (malignant tumors, nephrotic syndrome, anticoagulant syndrome, etc.), etc. The occurrence of blood coagulation leads to blood loss in the patient, which is not conducive to the patient's prognosis. Therefore, in the management of hemodialysis coagulation, it is particularly important to identify the signs of coagulation early and take preventive measures to avoid serious blood loss caused by blood coagulation blocking the tubes.

[0003] At present, clinical identification of coagulation signs is mainly through the operator's naked eye, which is highly subjective. There are mainly four coagulation signs in clinical practice: 1. The color of the extracorporeal blood is significantly deepened; 2. Dark shadows or stripes appear in the dialyzer; 3. Blood clots or foam can be seen in the small pot; 4. The dialysis manager shakes with the blood pump, and the dialyzer or venous small pot coagulates, causing the blood flow to be unable to pass smoothly and return; 5. The machine pressure alarm, the increase of venous pressure and transmembrane pressure indicate the blockage of the pipeline (but it often lags behind, the venous pot will cause the venous pressure to increase when the filter is blocked, and the pressure change is not large when the filter is not blocked. The large-scale drop of the upper thrombus will cause the venous pot to be severely blocked, and in severe cases, the extracorporeal blood cannot be returned).

[0004] In clinical practice, a flashlight is often used to observe the thrombosis of a venous or arterial pot. A device for detecting blood coagulation of an arterial or venous pot is disclosed in Chinese patent CN216117297U. The device comprises a horizontally arranged guide seat and a searchlight seat arranged vertically to the guide seat.

However, when the device is used in conjunction with a venous pot or an arterial pot, the incident direction of the searchlight source is fixed, and the detection is not accurate enough. In addition, the light source is fixed in a searchlight seat. When the specifications of the venous pot or the arterial pot are different, a searchlight seat of the same size needs to be customized to ensure that the light source is close to the pot wall, making it inconvenient to use.
