Description

Visual radial artery compression hemostat for emergency treatment and use method thereof Technical Field The invention relates to the technical field of medical equipment, in particular to a visual radial artery compression hemostat for emergency treatment and a use method thereof. Background In the field of emergency medicine, radial artery puncture is a common technical means for performing arterial blood gas analysis, invasive blood pressure monitoring and partial interventional diagnosis and treatment operations. After the puncturing operation is finished, effective and safe compression hemostasis is an important link for the puncturing point. The current common compression hemostasis method in clinic comprises manual compression and the use of various compression hemostats. The manual compression mode consumes a great deal of time and energy for medical staff, and the compression force is difficult to keep constant. The existing mechanical compression hemostat generally adopts a binding band to fix a compression head at a puncture point, and applies pressure through mechanical structures such as a screw rod or a buckle. When the existing compression hemostat is used, a plurality of defects still exist: When a patient moves limbs due to pain, discomfort or unconsciousness or is jolt in the process of transferring the patient (such as ambulance transportation), the haemostat body is easy to relatively displace with the skin of the patient, so that the compression head deviates from the puncture point, and the risk of re-bleeding is caused; The bottom of the existing compression pad is mostly made of smooth polymer materials, when contacting sweat, blood or disinfectant, a lubricating layer is formed between the skin and the compression pad, so that friction force is reduced sharply, the compression pad is difficult to maintain and position only by tightening force of a binding belt, lateral sliding is easy to occur, compression points are offset, and risk of re-bleeding is increased; The traditional hemostat has constant pressure once set, and a nurse has to manually unscrew nuts every 1-2 hours to recover venous return, so that when a major disaster or emergency is extremely busy, the remote limb of a patient is extremely easy to be subjected to long-time ischemia caused by forgetting, and the limb amputation risk is extremely high. Disclosure of Invention The invention aims to solve the core technical defects of the existing hemostat in a high-frequency scene of emergency transport jolt/limb movement, namely that the compression head is deviated to cause rebleeding due to unstable positioning, the remote limb is subjected to long-time ischemia, nerve injury and even limb amputation risks due to constant pressure, and the compression force cannot be objectively and intuitively monitored, so that the blindness which completely depends on the experience of medical staff is regulated, and provides a visual emergency radial artery compression hemostat and a use method thereof. In order to achieve the above purpose, the present invention adopts the following technical scheme: a visual emergency radial artery compression hemostat comprising: the fixing plate is provided with a binding mechanism for binding the fixing plate on the limb of the patient; the protective cover is movably arranged in the bottom abdication groove at the bottom of the fixed plate, and high-viscosity silicone oil is filled in the protective cover; The pressure head is arranged below the protective cover and used for pressing the radial artery; the driving mechanism comprises a piston disc I which is connected in a sliding and sealing manner in the protective cover and an air bag which is arranged in the pressure head, and when the piston disc I moves downwards, silicone oil in the protective cover is injected into the air bag, so that the air bag expands and drives the pressure head to move downwards; A yielding mechanism connected between the fixed plate and the protective cover for absorbing the relative displacement between the fixed plate and the protective cover by elastic deformation when the fixed plate moves along with the limb, so that the protective cover and the pressure head keep static at the pressing position, and The pressure reducing mechanism comprises an energy storage element for providing continuous driving force for the compression action and an orifice arranged on the piston disc I, the pressure exerted by the energy storage element enables the silicone oil below the piston disc I to slowly flow to the upper side of the piston disc I through the orifice under the continuous pressure, so that the automatic pressure reduction of the compression pressure is realized, and the energy storage element is a cylindrical spiral spring I. In one possible design, the yielding mechanism comprises a fixed cylinder, a sliding rod and a cylindrical spiral spring II sleeved outside the fixed cylinder, wherein one ends of the fixed
