The application discloses a non-invasive real-time evaluation method and system for blood fluidity and a wearable device, and belongs to the technical field of biomedical signal processing and intelligent health monitoring. The method comprises the following steps: acquiring an event timestamp of a blood blocking device and a physiological signal of a blood health measurement module; automatically intercepting a signal segment of a recovery stage based on the event timestamp; parallelly calculating a plurality of independent indexes characterizing the recovery process; performing validity checking on each index, and eliminating invalid or abnormal candidate values; and outputting a final recovery time after blocking by using a dynamic adaptive fusion strategy. The application further discloses a detection system and a wearable device for realizing the method. The application uses recovery kinetics after pressure relief to represent blood fluidity, realizes automatic and accurate detection of the recovery time through a multi-index cooperative judgment and a dynamic fusion mechanism, effectively suppresses noise interference and improves robustness, and can be used for non-invasive evaluation of vascular elasticity, blood viscosity and microcirculation function.

The utility model discloses a hemoperfusion device, relates to the technical field of blood purification, it includes the cylinder, be provided the inlet end cover and the outlet end cover of cylinder both ends respectively, and heating device, the heating device is used for raising the temperature in the cylinder and maintains at the specified temperature, the utility model provides a hemoperfusion device. When treatment is carried out, the heating device is turned on to heat the interior of the cylinder body and maintain the temperature at the specified temperature, so that the conditions of viscosity increase and fluidity reduction caused by temperature reduction of blood are avoided, the risk of blood coagulation is reduced, meanwhile, the conditions of hypothermia are reduced, and the problems that the viscosity increase of the blood is caused by temperature reduction and the fluidity of the blood is reduced are solved. The problem that the treatment effect is affected due to reduction of the adsorption surface area of resin microspheres caused by mutual adhesion of the resin microspheres after the resin microspheres in the perfusion device are in contact with the blood is solved.

This invention discloses a deer blood peptide for improving qi deficiency and blood stasis, its preparation method, and its application, belonging to the field of functional peptide technology. The deer blood peptide prepared using the method provided by this invention has a molecular weight of less than 3000 Da, making it easily absorbed and utilized by the body, and exhibiting high bioactivity. While obtaining the low molecular weight deer blood peptide, it can also effectively release heme, achieving a rapid blood-replenishing effect. It also contains small-molecule unsaturated fatty acids, which help lower blood lipids and improve blood flow, theoretically having a good effect on improving qi deficiency and blood stasis. Experimental results also show that the prepared deer blood peptide alone can effectively improve qi deficiency and blood stasis. It can effectively avoid the toxic side effects of harmful bacteria and their metabolites; it has a high yield and good flavor; it is simple and easy to operate, with mild conditions and low equipment requirements; it has high safety and is environmentally friendly; it produces no by-products, has low preparation costs, and high bioavailability of the material.
