Description
Technical Field
The invention relates to the field of medical treatment, in particular to a real-time coagulation treatment system for a wound of a patient.
Background
Medically, blood flows out of the heart and blood vessels, called hemorrhage (hemorrhage), and blood flows out of the body cavity or tissue, called internal hemorrhage, and external hemorrhage.
Bleeding can be classified into both ruptured bleeding and leaky bleeding according to the mechanism of blood escape.
Disruptive bleeding is caused by rupture of the heart or blood vessel walls. Rupture can occur in the heart (such as rupture of a cardiac wall tumor) and in arteries, and can be caused by lesions of the arterial wall itself (such as aortic aneurysm) or by erosion of the arterial wall due to paraarterial lesions (such as destruction of pulmonary vascular wall by tuberculosis cavity, erosion of local vascular wall by cancer tissues of lung cancer, gastric cancer and cervical cancer, and erosion of blood vessels at ulcer bottom of chronic ulcers of stomach and duodenum by lesions). The cause of venous rupture bleeding in addition to trauma, a more common example is rupture of esophageal varices during cirrhosis. The disruptive bleeding of capillaries occurs in localized soft tissue injuries.
This bleeding is due to increased permeability of the vessel wall in the posterior capillary vein, capillary vessels, and anterior capillary arteries, and leakage of blood out of the lumen through enlarged endothelial interstitial spaces and damaged vascular basement membrane. Spontaneous bleeding, i.e., bleeding which occurs when hemorrhagic diathesis is present, is leakage bleeding.
At present, whether the bleeding amount of the wound of the patient in the operation state is over-limit or not can not be detected and correspondingly dealt with by adopting an electronic solution, so that the work is still required to be specifically executed by medical staff, and the work burden of the medical staff is increased.

(1) detecting whether the bleeding amount of the wound of the patient in the operation state exceeds the limit or not, and sending a bleeding warning signal to trigger the thrombin to be injected into the human body when excessive bleeding occurs;
(2) in the operation of performing thrombin injection into a human body, the dose of thrombin injected into the human body is proportional to the amount of bleeding;
(3) the time interval of the thrombin injection mechanism for injecting the thrombin again exceeds the preset time length so as to avoid injecting the thrombin too frequently.
According to an aspect of the present invention there is provided a real-time coagulation treatment system for a wound of a patient, the system comprising:
a blood delivery tube inserted into a wound of a patient in an operative state for supplying blood to the patient in the operative state;
the injection port of the thrombin injection mechanism is connected with the blood transfusion tube at the wound and used for determining the injection of thrombin with corresponding dosage to the blood transfusion tube through the injection port based on the number of blood pixel points in the nearest neighbor interpolation image when a bleeding warning signal is received;

wherein, the step of determining the injection of thrombin with corresponding dosage to the blood transfusion vessel through the injection port based on the number of blood volume pixel points in the nearest neighbor interpolation image comprises the following steps: the number of the blood volume pixel points is in direct proportion to the determined thrombin dosage;
wherein, the time interval of the thrombin injection mechanism for injecting the thrombin for the second time exceeds the preset time length.
