Experimental result 1: measuring local skin blood perfusion amount by using a laser Doppler micro-area hemograph, and discussing the optimal compression pressure range of arterial hemorrhage of limbs; the subject is extremely key in selecting the pressure hemostasis range, and the difference of the local skin blood perfusion volume of the upper limb at different time points before, after and after the tourniquet is pressurized has statistical significance. The Tjf basic value comparison difference before pressurization among the four pressures has no statistical significance (P is more than 0.05), the blood flow perfusion amount is respectively reduced by 67.22 percent, 61.9 percent, 63.5 percent and 62.7 percent compared with the basic value immediately after pressurization to 30mmHg, 50mmHg, 80mmHg and 100mmHg above the systolic pressure, and the difference compared with the basic value has statistical significance (P is less than 0.01), and the difference among the four pressures has no statistical significance.

Study results 2: the condition statistics of tourniquet pressure hemostasis complication surgeons have no statistical significance on the evaluation difference of the using effect of tourniquets of limbs on two sides. The operation room nurse observes local skin indentation, local red swelling, local bleeding point, limb swelling, skin blister and the like under different tourniquet inflation pressures, and the comparison difference between the experimental limb side and the control limb side has no statistical significance.

The clinical trial result that the pressure of the elastic bandage pressing tissues in the scheme is smaller shows that the downward pressure of the hemostatic bandage in the scheme is smaller than that of the clamping tourniquet when hemostasis is effectively performed. The elastic bandage has a wider area, has the characteristics of softness, ventilation and comfortable subjective feeling, but has small compression force and poor hemostatic effect under the condition of heavy bleeding. The hemostatic bandage in the scheme adopts the principle of a tightening pressure method, so that the bandage can generate larger pressure to achieve the effect of effectively stopping bleeding. The pad accessory is used for raising at the bleeding point, so that the pressure is concentrated at the bleeding point, and under the same hemostatic effect, the pressure applied to other points around the limb is smaller, part of collateral circulation is reserved, and ischemic injury is reduced.

The elastic bandage in the scheme keeps partial blood circulation of limbs, the skin temperature reduction range of the hemostatic bandage in the scheme is lower than that of a clamping type tourniquet, the wound blood vessel hemostasis is realized by using unbalanced pressure, partial collateral circulation is kept, and the ischemia degree is reduced, so that the limbs are better protected, and serious consequences such as tissue necrosis and amputation caused by ischemia injury are avoided.

The elastic bandage in the scheme causes less skin injury, and the skin necrosis or burning injury under the tourniquet can be caused by the unevenness and the tiny movement of the tourniquet cuff. The cassette type tourniquet has no protective pad, has rough contact surface with the skin, and the skin is continuously pressed roughly after binding, which is easy to cause red, swelling, small blister and the like of the skin. In the binding process, if the tourniquet shifts, the rough and uneven contact surface can rub against the skin, which is easy to cause the skin damage. In addition, the pressure of the clamping tourniquet on limbs is large, the backflow of the terminal vein is blocked after the blood flow is blocked, the pressure in the blood vessel is increased, and the micro blood vessel is broken to form a bleeding point. The contact surface of the hemostatic bandage and the skin in the scheme is provided with a smooth dressing pad, so that the skin injury caused by long-time compression and friction is reduced. The skin after release of hemostasis showed only erythema and resolved rapidly.

The elastic bandage in the scheme has better comfort, the pain feeling and nerve paralysis of the hemostatic bandage in the scheme are both smaller than those of a clamping type tourniquet, and a patient feels more comfortable during hemostasis.

The elastic bandage in the scheme causes less limb edema, and the tourniquet causes damage to microcirculation, possibly causing limb edema. Edema is often caused by too long a time frame or too high a pressure on the tourniquet, and occurs to a degree consistent with the degree of muscle ischemia distal to the tourniquet. In the scheme, the arm circumference is thickened after the tourniquet is loosened, the clamping type tourniquet is larger than the tourniquet in the scheme, so that limb edema is caused, and the tourniquet in the scheme is superior to the clamping type tourniquet.

Clinical trial proves that the structure is reasonable in design and safe and reliable in use. Is superior to the clamping tourniquet in comfort and limb injury reduction. And can be used for binding and fixing the head, the trunk and the limbs, has the characteristic of multiple functions, and can reduce the equipment quantity and volume, thereby being a convenient choice for medical personnel to rescue the wounded with traumatic hemorrhage.

The working principle of the invention is as follows:

the bleeding pressure measuring method comprises the steps of dividing the bleeding source into an arterial bleeding group and a venous bleeding group, subdividing the bleeding position into upper limb blood vessels, lower limb blood vessels and head and neck blood vessel subgroups according to the bleeding position, simply cleaning bleeding wounds, measuring the optimal bleeding pressure of a patient by adopting a sphygmomanometer, and carrying out statistical analysis to obtain the optimal compression pressure range of the arterial and venous bleeding of the upper limb, the lower limb and the head and neck.

The elastic band 8 is synthesized by adopting an artificially synthesized high polymer material and a natural macromolecular material chitosan, has a good mechanical function and is a composite dressing with high biocompatibility, the upper layer of the elastic band 8 is used as a physical barrier by providing mechanical support by using hyaluronic acid and polycaprolactone, the lower layer of the elastic band 8 is used for increasing the biocompatibility by blending chitosan and zein, and the dressing is filled with salicylic acid which can increase the antibacterial and anti-inflammatory functions.

The matching of the inflatable saccule 7 and the pressure gauge is used for detecting the arteriovenous bleeding pressure of different parts, different inflation pressures are selected, a blood coagulation waterfall starting mechanism is considered, gelatin microsphere loaded hemostatic factors are added into the materials for pressing the large saccule 1 and the small saccule 2, the aggregation of platelets can be activated, the platelets are adsorbed, activated, physiological blood coagulation is generated, bleeding is reduced, and the purpose of rapid hemostasis is achieved by stimulating blood vessel regeneration through the activated platelets and pressurizing and pressing the large saccule 1 and the small saccule 2.
