Description

Technical Field

[0001] The utility model relates to the field of blood coagulation instruments, and more specifically to a blood coagulation instrument for monitoring the stable dose of warfarin after heart valve replacement. Background Art

[0002] Patients who have undergone mechanical valve replacement surgery need long-term oral anticoagulant treatment, mainly warfarin, and need to adjust the dosage of warfarin based on regular coagulation test results, mainly including the international normalized value (INR) and thrombin time (PT). If the dosage is large, the INR value will increase, resulting in gingival bleeding, subcutaneous bleeding, and even cerebral hemorrhage and gastrointestinal bleeding in severe cases; when the dosage is small, the INR will decrease, and there is a risk of embolism. In severe cases, cerebral infarction, pulmonary embolism, lower limb embolism, etc. may occur. Whether the coagulation results are high or low, it will cause serious complications and even endanger life.

[0003] While patients who have undergone heart valve replacement surgery are mainly treated with warfarin, when using a convenient coagulation analyzer to test the coagulation results, the patients are required to draw blood manually, and the blood sample requires a whole drop of complete blood. Improper operation during manual blood squeezing can easily cause blood sample contamination and delay the golden time for blood drawing. The risk of blood sample failure is greatly increased, which is not conducive to ensuring the treatment efficiency of the coagulation analyzer for patients who are mainly treated with warfarin. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a coagulation meter for monitoring the stable dose of warfarin after heart valve replacement surgery. When in use, the inflated blood squeezing air bag cooperates with the touch sensor to squeeze the two sides of the blood drawing finger, so as to facilitate the rapid and comprehensive dripping of blood, avoid the risk of blood sample contamination and delay of the golden time for blood drawing caused by artificial blood squeezing, and help to improve the speed of auxiliary squeezing of the bleeding site of the blood drawing finger, avoiding the risk of blood sample failure.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A coagulation meter for monitoring the stable dose of warfarin after heart valve replacement surgery comprises a coagulation meter body, a detection slot is provided on the front side of the upper end of the coagulation meter body, both left and right ends of the detection slot are fixedly connected with inflation chambers, the inner end of the inflation chamber is fixedly connected with a micro airbag, the left and right inner walls of the detection slot are symmetrically fixedly connected with expansion and blood squeezing airbags, the two expansion and blood squeezing airbags are respectively connected with the output ends of the corresponding micro airbags, the ends of the two expansion and blood squeezing airbags that are close to each other are fixedly connected with touch sensors, and the touch sensors are located at the highest protruding point of the expansion and blood squeezing airbags.

[0009] Furthermore, a detection plate is placed on the lower inner wall of the detection slot, and the detection plate is snapped into the body of the coagulation analyzer.

[0010] Furthermore, a blood-collecting finger is placed at the inner end of the detection notch, and the blood-collecting finger is located between the two inflated blood-squeezing air bags.

[0011] Furthermore, the blood sampling finger is located directly above the detection plate, and a rotating shaft is rotatably connected between the left and right inner walls of the detection slot.

[0012] Furthermore, a mirror plate is fixedly connected to the outer end of the rotating shaft, and the mirror plate cooperates with the detection notch.

[0013] Furthermore, a display screen is fixedly connected to the upper end of the coagulation instrument body, and a plurality of power supply interfaces are fixedly connected to the right end of the coagulation instrument body.

[0014] Furthermore, a plurality of bottom suction cups are fixedly connected to the lower end of the coagulation instrument body, and the plurality of bottom suction cups are respectively located at the four corners of the lower end of the coagulation instrument body.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) When using this scheme, the belly of the blood-drawing finger is punctured with a disposable needle to draw blood. After puncturing, the blood-drawing finger is immediately placed downward in the detection slot of the coagulation analyzer body. At this time, the inflatable blood-squeezing air bags on both sides of the blood-drawing finger are inflated by the micro-air bags in the inflation chamber. The inflated blood-squeezing air bags squeeze the positions on both sides of the blood-drawing finger, so that the blood in the blood-drawing finger can be quickly and comprehensively dripped into the designated position on the detection plate. The detection plate can be measured by the coagulation analyzer body to obtain the test results, avoiding the risk of blood sample contamination caused by artificial blood squeezing and delaying the golden time for blood collection.

[0018] (2) When the two blood-drawing fingers extend between the two inflatable blood-squeezing air bags, the touch sensor arranged between the two inflatable blood-squeezing air bags contacts the blood-drawing fingers. After the touch sensor receives a signal, the connected controller can immediately start the micro air bag to inflate the inflatable blood-squeezing air bag, which is beneficial to improve the speed of auxiliary squeezing of the bleeding part of the blood-drawing fingers and avoid the risk of blood sample failure due to delay for too long.

[0019] (3) At the same time, when the blood-drawing finger is bleeding, a mirror stand with a reflective function is set on the front side of the detection slot. The mirror stand can facilitate the patient to check the bleeding situation at the bleeding site in real time, avoid the problem of insufficient bleeding volume or insufficient blood drop accuracy caused by the skewed bleeding point, and help to ensure the patient's detection efficiency. After use, the mirror stand can be flipped through the shaft and placed horizontally with the lower wall of the detection slot, which is convenient for storing the mirror stand and carrying the entire coagulation analyzer body.
