Description
Technical Field
The invention belongs to the technical field of hemostasis compressor, and particularly relates to a hemostasis compressor for a department of cardiology.
Background
The use of hemostatic paddles in the cardiology department is one method for controlling bleeding or reducing the amount of bleeding, and hemostatic paddles are commonly used to treat intravascular bleeding, such as in vascular interventions or cardiac catheterization procedures, by applying sustained pressure on the bleeding site to prevent or reduce blood flow, thereby helping to stop bleeding, which may prevent further complications from bleeding, and provide a better operating environment for the physician.
The hemostatic pressure in use of the current hemostatic compressor is mostly regulated by medical staff, and the following problems exist in actual use:
1. the hemostatic compressor needs to be pressed again in a heavy way to promote thrombus formation at a puncture port in the early use period, and is pressed again in a light way to maintain compression after the thrombus is formed, so that the thrombus is consolidated, and as the physical constitution and the injury situation of each wounded are different, the time for thrombus formation is also different, and the thrombus formation can not be sensed in time only by manually adjusting the pressure, so that the initial high pressure can cause larger compression on the thrombus, the thrombus formation can cause blood flow to be blocked or weakened, and the healing of the wound can be influenced instead by the fact that the compression force can not be adjusted in time;
2. under the conditions that the main bleeding, arterial bleeding and the physical constitution of some wounded cause the difficulty of self coagulation, larger hemostasis compression force is needed initially, and intermittent buffer release is needed during the use period of the hemostasis compressor so as to ensure the necessary blood supply requirement, avoid the restricted blood flow caused by unsmooth blood circulation and further lead to the occurrence of dangerous situations of hypoxia of local tissues of the wounded body or weakening of pulse of limbs, but because of the different physical constitutions of the wounded body, the blood circulation at blood vessels can be kept in a stable state when some wounded body are subjected to hemostasis compression of large pressure, and the physical constitution of some wounded body is bad, under the hemostasis compression condition of the initial large pressure, the frequency of buffer release is reduced, the hemostasis compression time of the large pressure is further increased, the healing efficiency of the wound is improved, the frequency of buffer release is further improved, the smoothness of blood circulation is further ensured, and the problem that the physical function is influenced by unsmooth blood flow is avoided.
For this reason, we propose a hemostatic compressor for cardiology to solve the above-mentioned problems.

The principle of operation of the present invention will now be described as follows: the hemostatic press plate 1 is applied to a wound, the biaxial motor 32 is started again, the biaxial motor 32 drives the two rotating screws 33 to synchronously rotate, the moving plate 34 is matched with a plurality of extension rods 35 to drive the extension supporting blocks 36 to move outwards through the threaded sleeving action of the rotating screws 33 and the moving plate 34, the relative length of the whole middle shell 31 is prolonged, the supporting stability of the hemostatic press plate 1 is improved, the winding motor 24 is started through the PLC 11, the winding motor 24 drives the winding and unwinding cylinder 23 to rotate through the rotating shaft 22, the binding belt 10 is further tightened, the hemostatic press plate 1 is tightly pressed at the hemostatic wound, medical staff can adjust the initial hemostatic press force according to the bleeding condition and the bleeding position of a wounded, rapid hemostatic press operation can be carried out, the whole structure is stable, and the stability of the hemostatic press operation is ensured;
when hemostasis pressing is started, a weak high-frequency alternating current is input to the skin through the PLC 11 in combination with the power supply electrode plate 81, the receiving electrode plate 82 is used for measuring the voltage on the path of the current passing through the skin, when blood flows through a measured part, the conductivity of the skin and tissues is changed, the current path passing through the skin is changed, the electrical impedance is further changed, the conductivity is correspondingly increased along with the increase of the blood flow rate, the electrical impedance on the path of the current passing through the skin is further reduced, when the power supply electrode plate 81 is powered, the power supply circuit of the thrust electromagnetic plate 76 is synchronously communicated, and the power supply electrode plate 81 and the receiving electrode plate 82 are electrically connected to the power supply circuit of the thrust electromagnetic plate 76, so that the difference of the resistance between the power supply electrode plate 81 and the receiving electrode plate 82 caused by the change of the blood flow rate is directly fed back to the power supply size of the thrust electromagnetic plate 76;
when the blood flow rate is low, the resistance between the power supply electrode plate 81 and the receiving electrode plate 82 is relatively high, so that the power supply current of the thrust electromagnetic plate 76 is low, the magnetism of the thrust electromagnetic plate 76 is weak, the moving distance of the sliding plate 73 is small by matching with the thrust permanent magnet plate 77, the power supply conducting block 74 is in contact with the power supply conducting block 75 at the rear side, and is further communicated with a high power supply voltage circuit of the gear motor assembly 66, as the gear motor assembly 66 is a direct current motor, under the condition of high power supply voltage, the rotating speed of the gear motor assembly 66 is fast, the first transmission shaft 64 is driven by the gear motor assembly 66 to drive the moving speed of the first pressing block 68 to be fast, so that the first pressing block 68 can be pushed to act on the buffer release trigger switch 610 more quickly, the feedback signal of the buffer release trigger switch 610 is fed back to the PLC controller 11, the PLC controller 11 firstly cuts off the power supply of the positioning electromagnetic plate 26, then reversely drives the winding motor 24 to act, relatively releases the tightening belt 10 for 5 seconds, then drives the winding motor 24 to return to the initial set fastening position, and then the positioning electromagnetic plate 26 is matched with the positioning plate 27 to realize the fixation of the magnetic receiving cylinder 23;
