DETAILED DESCRIPTION

[0023] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 As shown, the intelligent pressurized femoral artery hemostasis device proposed in the present invention includes a main body 1. Auxiliary positioning modules 2 are arranged at both ends of the main body 1, tightening belts 3 are arranged on both sides of the central position of the main body 1, a blood oxygen detection module 4 is arranged on the outside of the auxiliary positioning module 2, a first pressing module 5 and a second pressing module 6 are arranged in sequence between the two blood oxygen detection modules, and an acceleration sensor 7 is arranged at the upper end of the main body 1. A central processing module is arranged inside the main body 1 to control the working process of the intelligent pressurized femoral artery hemostasis device.

[0025] like Figure 2As shown, the auxiliary positioning module 2 is arc-shaped as a whole to better fit the patient's legs and stabilize the intelligent pressurized femoral artery hemostasis device. A first micro air pump 21 is arranged inside the auxiliary positioning module 2, and a first air inlet 24 and a second air inlet 26 are arranged at both ends of the auxiliary positioning module 2. The first micro air pump 21 is connected to the first air inlet 24 and the second air inlet 26 through a first air pipe 22. A first air valve 23 is arranged between the first micro air pump 21 and the first air inlet 24, and a second air valve 25 is arranged between the first micro air pump 21 and the second air inlet 26. The central processing module determines whether the patient's legs are shaking based on the data from the acceleration sensor 7. If the patient's legs are not shaking, the first micro air pump does not work, and the auxiliary positioning module 2 fits the patient's legs with the help of the arc shape. When the patient's legs are shaking, the central processing module determines the direction of the shaking based on the data from the acceleration sensor 7, opens the air valve corresponding to the air intake port in the opposite direction of the shaking, and the first micro air pump starts working to form a negative pressure in the air intake port, and adsorbs the intelligent pressurized femoral artery hemostasis device to the leg to offset the impact of the shaking on the intelligent pressurized femoral artery hemostasis device. For example, when the patient's legs shake to the right, the first air valve 23 is opened, and the first micro air pump 21 starts working. When the patient's legs shake to the left, the second air valve 25 is opened, and the first micro air pump 21 starts working.

[0026] like Figure 3 As shown, the tightening belt 3 is used to fix the intelligent pressurized femoral artery hemostasis device, including an annular airbag 31 and a protective pad 32. A second micro air pump is arranged inside the main body 1, and the second micro air pump is connected to the annular airbag 31 through a second air tube. The second micro air pump can inflate and deflate the annular airbag 31. The annular airbag 31 can be closer to the patient's leg in the inflated state to achieve a better fixation effect. The protective pad 32 is arranged on the inner side of the bottom of the annular airbag 31, and is made of silicone material, which can play a role in buffering and shock absorption, and improve the comfort of use.

[0027] like Figure 4As shown, the blood oxygen detection module 4 includes a red LED 41, a phototransistor 42, an infrared LED 43, a signal processing circuit 44 and a processor 45. The red LED 41, the phototransistor 42 and the infrared LED 43 are facing the patient's legs, and the red LED 41 and the infrared LED 43 are arranged on both sides of the phototransistor 42. The signal processing circuit 44 and the processor 45 are arranged inside the blood oxygen detection module 4, and the signal processing circuit 44 is connected to the phototransistor 42 and the processor 45 respectively. During the detection process, the red LED 41 and the infrared LED 43 emit light alternately according to the set light intensity, the phototransistor 42 receives the reflected light and generates a weak current signal, and the signal processing circuit 44 performs pre-amplification, filtering and denoising, and AC / DC separation processing on the weak current signal to obtain four signals, namely, a DC signal caused by red light, an AC signal caused by red light, a DC signal caused by infrared light, and an AC signal caused by infrared light. The processor 45 calculates the light absorption reflectance ratio based on the Lambert-Beer law, and compares the light absorption reflectance ratio with the data stored in advance to obtain the blood oxygen saturation.

[0028] The first pressing module 5 performs compression and hemostasis on the puncture wound. Figure 5 As shown, a first pressing unit 52 is disposed in the center of the first pressing module 5, and micro cameras 51 are disposed at the four corners of the first pressing module 5. Figure 6As shown, the first pressing unit 52 includes a base 521, the surface of the base 521 is provided with a cross-shaped track, and a first telescopic rod 522 is provided in the center of the cross-shaped track. One end of the first telescopic rod 522 can move along the cross-shaped track toward eight directions, namely, due north, northeast, due east, southeast, due south, southwest, due west, and northwest, and the other end of the first telescopic rod 522 is connected to a silicone compression block 523. A core 525 is provided on the upper surface of the silicone compression block 523, and a power supply 524 and an LED lamp bead 526 are provided on both sides of the silicone compression block 523, respectively. The core 525 is connected to the power supply 524 and the LED lamp bead 526 through metal wires. The impedance of human skin is relatively large in a dry environment, and the LED lamp bead 526 is in an off state under normal circumstances. However, the blood contains conductive components such as various inorganic salts. If the core 525 absorbs more blood, the impedance will be reduced, and the LED lamp bead 526 will be lit. The more blood absorbed, the brighter the LED lamp bead 526 will be. A light sensor 527 is disposed on the surface of the base 521 at a position corresponding to the LED lamp bead 526. The light sensor 527 is used to detect the brightness of the LED lamp bead 526. Specifically, the LTR-329ALS of Lite-On Corporation can be selected. A light shielding plate 528 is disposed on the edge of the surface of the base 521 to surround the light sensor 527 and the first telescopic rod 522 to shield light from the environment and improve the detection accuracy of the light sensor 527. The micro camera 51 captures the image around the first pressing unit 52 and monitors whether the first pressing unit 52 is offset according to whether the puncture wound is identified.

[0029] The second pressing module 6 mainly presses the proximal end of the puncture wound to assist in hemostasis. Figure 7 As shown, the second pressing module 6 includes a second telescopic rod 61 and an inflatable base 62. A third micro air pump is arranged inside the inflatable base 62. An annular pressing airbag 63 is arranged on the surface of the inflatable base 62. The third micro air pump inflates and deflates the annular pressing airbag 63. A plurality of pressure sensors 64 are evenly arranged on the surface of the annular pressing airbag 63 in contact with the patient. The inflation pressure of the third micro air pump can be adjusted according to the pressure data to ensure the comfort and safety of the pressing.

[0030] Under the control of the central processing module, the intelligent pressurized femoral artery hemostasis device can achieve:

[0031] 1) Detect the offset of the first pressing module 5, adjust the pressing position of the first pressing module 5, and ensure that the first pressing unit 52 is facing the puncture wound. Specifically, the micro camera 51 captures the image around the first pressing unit 52, and determines whether the puncture wound appears in the image through image recognition. If the puncture wound does not appear in the images captured by each micro camera, it means that the first pressing unit 52 is facing the puncture wound and no adjustment is required. If the puncture wound appears in the images captured by the micro camera, it means that the first pressing unit 52 is offset. According to the specific position of the puncture wound, the first pressing unit 52 moves along the cross-shaped track to align with the puncture wound.

[0032] 2) Adjust the pressing strength of the first pressing module 5 and the second pressing module 6 according to the blood oxygen data and the bleeding situation. Specifically, according to the data of the pressure sensor 64, adjust the second pressing module 6 to the maximum safe pressing strength. The first pressing module 5 adjusts the pressing pressure of the silicone compression block 523 through the first telescopic rod 522 until the detection data of the light sensor 527 does not change, indicating that the bleeding has stopped at this time. The pressing strength of the second pressing module 6 is adjusted according to a specific time interval (for example, 10 minutes) and adjustment range until the second pressing module 6 is separated from the patient. After each adjustment of the pressing strength of the second pressing module 6, the pressing strength of the second pressing module 6 is adjusted according to whether the data of the light sensor 527 changes. The bleeding situation is judged by the blood oxygen detection module 4 at both ends of the intelligent pressurized femoral artery hemostasis device. If the data of the light sensor 527 increases, it means that bleeding has occurred, and the pressing pressure of the first pressing module 5 needs to be increased until the detection data of the light sensor 527 does not change. If the data of the light sensor 527 does not change, it means that no bleeding has occurred and there is no need to adjust the pressing pressure of the first pressing module 5. When the second pressing module 6 is separated from the patient, the blood oxygen difference is calculated according to the blood oxygen detection module 4 at both ends of the intelligent pressurized femoral artery hemostasis device. If the blood oxygen difference is less than the safety threshold, the pressing pressure of the first pressing module 5 is increased until the safety threshold is reached. If the blood oxygen difference is greater than the safety threshold, the pressing pressure of the first pressing module 5 is reduced until the safety threshold is reached.

[0033] The above disclosure is only the preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the present invention. It should be pointed out that for those skilled in the art, any equivalent changes made to the scheme of the present invention without departing from the design structure and principle of the present invention are considered to be within the protection scope of the present invention.
