Description

Intelligent vascular puncture point hemostasis device and method based on AI image navigation and multi-mode feedback Technical Field The invention relates to the technical field of medical instruments, in particular to an intelligent pressurizing device for stopping bleeding at a puncture point after percutaneous vascular intervention operation (such as coronary angiography, heart stent implantation, lower limb arterial intervention and PICC catheterization) and a control method thereof, which are particularly suitable for clinical scenes requiring high-precision positioning, dynamic pressure regulation and active wound protection. Background After the radial artery, femoral artery or peripheral blood vessel puncture is used for interventional diagnosis and treatment, the puncture point needs to be effectively compressed for hemostasis so as to prevent complications such as bleeding, hematoma, pseudoaneurysm, vascular occlusion, thrombosis, infection of puncture parts and the like, wherein 24 hours after operation is a complication high-incidence period, and accurate hemostasis and dynamic monitoring are particularly critical. At present, a manual compression and mechanical pressurizer (such as TR BandTM), a vascular closure device or a simple compression dressing are commonly used in clinic, but the following outstanding problems exist: (1) The compression position is inaccurate, the traditional mode relies on visual and hand feeling positioning of medical staff, compression points are easy to deviate from actual puncture points due to body position variation in operation of a patient, limb movement or initial positioning deviation after operation, the existing image positioning device has the problems of insufficient identification precision and poor suitability, the body position cannot be quickly repositioned after the body position variation, radiation exposure and contrast agent use amount are high, and doctor-patient burden is increased. (2) The compression pressure is static cured and single in regulation, the pressure preset is completely dependent on clinical experience of medical staff and cannot be dynamically regulated along with bleeding state, blood pressure fluctuation, limb movement or tissue tolerance of a patient, delayed bleeding is easily caused by insufficient pressure, pain, skin injury, vascular occlusion or thrombosis are caused by excessive pressure, and the existing device mostly adopts a single pressure application mode and cannot adapt to individual differences of different puncture parts and patients. (3) The monitoring dimension is limited, early warning is delayed, the hemostasis process depends on intermittent manual observation, the existing monitoring device can only monitor single physiological parameters (such as pressure or blood flow), real-time monitoring of multidimensional parameters such as bleeding signals, tissue temperature, pressure distribution uniformity and the like is lacked, potential complications such as hematoma, infection and the like can not be found in time, and risk early warning is delayed. (4) The existing hemostatic device only can realize mechanical compression hemostasis, can not promote wound healing of puncture points, is high in material sensitization and poor in air permeability, is easy to cause skin irritation or infection, and is long in postoperative braking time, so that rehabilitation experience of patients is affected. (5) The operation efficiency and the intellectualization are insufficient, a part of the pressurizing device needs a plurality of medical staff to cooperatively operate, the real-time synchronization and the remote monitoring of data cannot be realized, the workload of the medical staff is large, and the rapid hemostatic treatment in emergency scenes is not facilitated. In addition, the existing biological hemostatic dressing has the capabilities of rapid hemostasis and healing promotion, but lacks the functions of accurate positioning and dynamic pressure regulation, cannot adapt to the accurate compression requirement after vascular intervention, and has the advantages of low cost, but lacking positioning accuracy and monitoring capability and higher risk of complications. Therefore, a hemostatic device which can realize accurate AI navigation positioning, multi-mode real-time monitoring, self-adaptive dynamic pressure regulation, active wound protection and high intelligent degree and has the advantages of clinical safety, practicability and economy is needed.
