[0027] Example 1:

[0028] like Figure 1-4As shown, the utility model is a femoral artery compression hemostasis device, comprising: a belt 1, which is used to be tied around the patient's waist; a front pad 2, which is connected to the bottom of the belt 1 and is connected to the rear pad 4; an airbag 3, which is connected to the inner side of the front pad 2 and one end of the airbag 3 is connected to the air pump 5; a controller 6, which is electrically connected to the air pump 5 and is provided with a display screen 7; a pressure sensor 8, which is arranged between the front pad 2 and the airbag 3 and is electrically connected to the alarm 9; and an adsorption cotton 10, which is arranged on the side of the airbag 3 away from the front pad 2.

[0029] In this embodiment, the waist belt 1 is first wrapped around the patient's waist and fixed, and then the front pad 2 and the rear pad 4 are fixed to the patient's buttocks through the inner thighs through the first strap 12 and the second strap 13, so that the airbag 3 is pressed on the gauze at the puncture point, and then the front pad 2 and the rear pad 4 are connected to the waist belt 1 through the first fixing belt 11 and the second fixing belt 14. By starting the air pump 5, the air is inflated into the airbag 3 until the target pressure of the airbag 3 is reached, which is approximately the same as the pressure value generated by a 1kg sand belt, and the pressure is measured in real time to ensure that the pressure of the airbag 3 is always within the required range. The cooperation between the controller 6, the air pump 5 and the airbag 3 achieves long-term stable pressure output, which solves the problems of uneven pressure, poor pressure maintenance, and easy displacement.

[0030] Specifically, the display screen 7 can display parameters such as real-time inflation pressure, target airbag 3 pressure, airbag 3 pressure holding time, and airbag 3 deflation pressure, thereby improving the intelligence of the device.

[0031] Among them, when the airbag 3 at the inguinal puncture site is loose, the pressure received by the pressure sensor 12 changes, and an alarm is sounded through the alarm 1, so that medical staff can discover it in time and make adjustments, so that the airbag 3 can be found to be falling off in time.

[0032] like Figure 2 and Figure 3 As shown, specifically, the front pad 2 is connected to the waist belt 1 through the first fixing belt 11 above, the back pad 4 is connected to the front pad 2 through the first strap 12 and the second strap 13, and the back pad 4 is connected to the waist belt 1 through the second fixing belt 14. The first strap 12 includes a first belt body 1201 and a second belt body 1202. The first belt body 1201 and the second belt body 1202 are connected by Velcro. One end of the first belt body 1201 is connected to the front pad 2, and one end of the second belt body 1202 is connected to the back pad 4. The first strap 12 and the second strap 13 have the same structure, and at least two first straps 12 are provided; by using Velcro to connect the first belt body 1201 and the second belt body 1202, the gap between the first belt body 1201 and the second belt body 1202 can be conveniently adjusted, which is convenient for use for patients of different body shapes. By adopting at least two first straps 12, the fixing effect can be enhanced.

[0033] The front pad 2 and the rear pad 4 can be easily separated by the first belt body 1201 and the second belt body 1202, so that the damaged part can be repaired and replaced at a later time without replacing the entire pad.

[0034] like Figure 2 and Figure 4 As shown, specifically, a threaded hole 15 is opened inside the front pad 2, and the threaded hole 15 is threadedly connected to the threaded rod 16, and one end of the threaded rod 16 is connected to the pressure sensor 8; by rotating the threaded rod 16, the position of the pressure sensor 8 is conveniently adjusted, and the pressure sensor 8 is conveniently taken out for inspection and replacement.

[0035] like Figure 2 and Figure 4 As shown, specifically, an arc-shaped pressing groove 17 is provided on the inner side of the front pad 2, and the airbag 3 is connected to the arc-shaped pressing groove 17 by Velcro. Breathing holes 18 are provided on the front pad 2 and the rear pad 4. The waist belt 1 is arranged in a strip structure, and the two ends of the waist belt 1 are connected by Velcro; the ventilation holes 18 facilitate ventilation of the front pad 2 and the rear pad 4, and the through holes 20 facilitate ventilation of the waist belt 1.

[0036] like Figure 1 As shown, a first reinforcement belt 26 is provided on one side of the waist belt 1, and a second reinforcement belt 27 is provided on the other side of the waist belt 1. The first reinforcement belt 26 and the second reinforcement belt 27 are respectively passed through the thighs from both sides of the waist belt 1, and then pasted and fixed to the back of the waist belt 1, forming a cross shape to pressurize and bind the front pad 2, thereby enhancing the stability of the airbag 3 extrusion.

[0037] like Figure 2 and Figure 3 As shown, specifically, the waist belt 1 is provided with a plurality of belt loops 19 and a plurality of through holes 20, and the first fixing belt 11 and the second fixing belt 14 pass through the belt loops 19 and are connected by Velcro; the first fixing belt 11 and the second fixing belt 14 are connected between the waist belt 1 and the front pad 2 and the rear pad 4, so that the front pad 2 and the rear pad 4 can be stably fixed to prevent the front pad 2 and the rear pad 4 from sliding and falling due to gravity.

[0038] Among them, by providing multiple belt loops 19 and adjusting the length of the first fixing belt 11 and the second fixing belt 14 extending out of the belt loops 19, the positions of the front pad 2 and the rear pad 4 can be easily adjusted, making it convenient to adapt to patients of different body shapes.

[0039] like Figure 2 and Figure 4 As shown, specifically, one end of the airbag 3 is connected to the air pump 5 through the air guide tube 21; when the air pump 5 works, the airbag 3 can be inflated and deflated using the air guide tube 21.

[0040] Example 2:

[0041] like Figure 5and Figure 6 As shown, a third strap 22 and a fourth strap 23 are respectively provided on both sides of the front pad 2, and a Velcro fleece surface 24 and a Velcro hook surface 25 are respectively provided on the third strap 22 and the fourth strap 23. By bonding the Velcro fleece surface 24 and the Velcro hook surface 25, the third strap 22 and the fourth strap 23 can stably bind the airbag 3, and at the same time, the waist belt 1 can also be a waist belt, which can enhance the binding effect on the patient.

[0042] Working principle: The staff first wraps the belt 1 around the patient's waist and fixes it, then fixes the front pad 2 and the back pad 4 under the patient's buttocks through the inner thigh through the first strap 12 and the second strap 13, so that the airbag 3 is pressed on the gauze at the puncture point, and then connects the front pad 2 and the back pad 4 to the belt 1 through the first fixing belt 11 and the second fixing belt 14. By starting the air pump 5, the air is inflated into the airbag 3 until the target pressure of the airbag 3 is reached, which is approximately the same as the pressure value generated by a 1kg sand belt, and the pressure is measured in real time to ensure that the pressure of the airbag 3 is always within the required range. The cooperation between the controller 6, the air pump 5 and the airbag 3 achieves long-term stable pressure output, which solves the problems of uneven pressure, poor pressure maintenance, and easy displacement.
