[0025] Compared with the prior art, the present application has the following advantages:

[0026] 1. Based on that the compression assembly is located in the connecting channel, the bottom of the compression assembly is designed with a compression surface matched with the skin area where the wrist puncture point of the human body is located, for example, a circular, elliptical or square compression pad with a soft surface. Based on that the compression assembly is connected with the lifting part, the compression assembly can be lifted with the lifting part, so as to press the wrist puncture point of the human body or separate the compression assembly from the wrist puncture point of the human body. When the lifting part of the driving mechanism moves downward under the driving of the driving mechanism, the compression assembly descends with the lifting part of the driving mechanism, and the compression surface of the compression assembly is pressed against the skin at the wrist radial artery puncture point, so as to realize compression of the vascular puncture point. Conversely, when the lifting part of the driving mechanism moves upward, the compression assembly is lifted, so as to reduce or eliminate the compression of the skin at the puncture point.

[0027] 2. The pressure sensor is installed on the compression assembly. The pressure sensor can be embedded inside the compression assembly or installed on the compression surface of the compression assembly. The pressure sensor abuts against the lifting part of the lifting mechanism. As a preferred installation method, the pressure sensor is installed at the connection between the compression assembly and the lifting part of the drive mechanism, thereby ensuring that the pressure sensor can effectively measure the pressure actually applied by the compression assembly to the puncture point of the patient's wrist during the compression hemostasis process, thereby providing a reference for medical staff.

[0028] 3. The near-infrared spectral sensor is installed in the compression assembly. The near-infrared spectral sensor can be embedded inside the compression assembly or installed on one side of the compression assembly. The emitting and receiving ends of the near-infrared spectral sensor face the puncture point. The near-infrared spectral sensor emits a near-infrared beam towards the puncture point on the wrist and receives the near-infrared beam returning from the puncture point. During operation, the near-infrared spectral sensor emits a near-infrared beam of a specific wavelength towards the wrist puncture point and subcutaneous tissue. This near-infrared beam penetrates the skin, is partially absorbed by hemoglobin in the tissue, and is partially reflected back. The receiving end of the near-infrared spectral sensor receives the near-infrared beam reflected from deep within the subcutaneous tissue and converts the optical signal into an electrical signal. Since hemoglobin can absorb near-infrared light of specific wavelengths, by analyzing the spectral characteristics of the returned light beam (e.g., changes in hemoglobin absorption of near-infrared light of specific wavelengths), the hemostasis status deep at the puncture site and the tendency for hematoma formation can be assessed. Specifically, if the absorption rate of hemoglobin to near-infrared light of specific wavelengths gradually increases, it indicates insufficient compression, blood accumulation at the puncture site, and a tendency for hematoma formation. If the absorption rate of hemoglobin to near-infrared light of specific wavelengths gradually decreases, it indicates excessive compression, blood coagulation, and a risk of radial artery occlusion.

[0029] 4. Based on the feedback signals from the pressure sensor and the near-infrared spectral sensor, the system achieves real-time pressure detection of the compression component on the skin at the puncture point. On the other hand, the control system can adjust the pressure according to the patient's coagulation status by repeatedly controlling the drive mechanism to rise, ensuring that the compression component can always apply appropriate pressure to the skin at the puncture point. This achieves rapid hemostasis and avoids radial artery occlusion caused by untimely decompression. Attached Figure Description

The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] As Figures 1-2 shown, a radial artery compression hemostasis device with real-time pressure monitoring function of a preferred embodiment of the present application, comprising: support seat 1, flexible connecting component 2, driving mechanism 3, compression assembly 4, pressure sensor 5, near-infrared spectrum sensor 6 and control system 7;

[0040] The working principle of the present application is that when in use, the patient's wrist is inserted through the annular connecting channel formed by the support seat 1 and the flexible connecting component 2, the flexible connecting component 2 is pulled tight to fix the device as a whole on the wrist, to ensure that the compression assembly 4 is directly above the puncture point, the control system 7 controls the driving mechanism 3 to gradually descend, driving the compression assembly 4 to gradually approach and compress the skin of the puncture point, at this time the reading of the pressure sensor 5 gradually increases, the data fluctuation detected by the near-infrared spectrum sensor 6 gradually tends to be stable, after the reading of the near-infrared spectrum sensor 6 remains stable, the driving mechanism 3 stops descending, at this time the reading of the pressure sensor 5 is the initial compression force; after a period of time, the puncture point starts to clot, the reading of the near-infrared spectrum sensor 6 appears a downward fluctuation, the control system 7 controls the driving mechanism 3 to rise, thereby driving the compression assembly 4 to rise, gradually reducing the compression force applied to the puncture point, after the reading of the near-infrared spectrum sensor 6 tends to be stable again, the control system 7 controls the driving mechanism 3 to stop descending again, and the compression assembly 4 maintains a stable compression force on the skin of the puncture point. According to the feedback signals of the pressure sensor 5 and the near-infrared spectrum sensor 6, on the one hand, real-time pressure detection of the compression assembly 4 compressing the skin of the puncture point is realized, and on the other hand, the pressure can be reduced in real time according to the actual situation to avoid excessive compression leading to radial artery occlusion.

[0041] The two ends of the flexible connecting component 2 are connected to the two ends of the support seat 1, the flexible connecting component 2 is usually made of magic tape, elastic bandage or woven tape with buckles, and the length is adjustable to adapt to the circumference of different patient's wrists, as an optional design, the two ends of the flexible connecting component 2 can be connected to the two ends of the support seat 1 in a detachable or fixed connection manner; based on the flexible connecting component 2 and the support seat 1 forming a connecting channel, the connecting channel is used in cooperation with the human wrist, the flexible connecting component 2 and the support seat 1 together enclose a connecting channel for the human wrist to pass through, based on binding the support seat 1 to the human wrist, the compression hemostasis device is stably bound to the wrist skin where the puncture point is located, avoiding displacement due to patient's activity, which is the premise of realizing accurate compression and monitoring.

[0042] The driving mechanism 3 is installed on the support seat 1, as a preferred installation manner, the driving mechanism 3 is installed on the support seat 1 by fasteners to ensure smooth movement of the driving mechanism 3, the driving mechanism 3 has a lifting part which can move linearly, for example, an electric push rod;

[0043] The compression assembly 4 is located in the connecting channel, and the bottom of the compression assembly 4 is designed with a compression surface matched with the skin area of the wrist puncture point of the human body, such as a circular, oval or square soft compression pad. Based on the connection of the compression assembly 4 and the lifting part, the compression assembly 4 can be lifted with the lifting part to press the wrist puncture point of the human body or separate the compression assembly 4 from the wrist puncture point of the human body. When the lifting part of the driving mechanism 3 moves downward under the driving of the driving mechanism 3, the compression assembly 4 descends with the lifting part of the driving mechanism 3, and the compression surface of the compression assembly 4 is pressed against the skin at the wrist radial artery puncture point, so as to realize the compression of the blood vessel puncture point. Conversely, when the lifting part of the driving mechanism 3 moves upward, the compression assembly 4 is lifted, thereby reducing or eliminating the compression of the skin at the puncture point.

[0044] The pressure sensor 5 is installed on the compression assembly 4, and the pressure sensor 5 can be embedded in the compression assembly 4 or installed on the compression surface of the compression assembly 4. The pressure sensor 5 abuts against the lifting part of the driving mechanism 3. As a preferred installation mode, the pressure sensor 5 is installed at the connection between the compression assembly 4 and the lifting part of the driving mechanism 3, so as to ensure that the pressure sensor 5 can effectively measure the pressure actually applied by the compression assembly 4 to the puncture point of the wrist of the patient during the compression hemostasis process, thereby providing a reference basis for medical personnel.

[0045] The near-infrared spectrum sensor 6 is installed on the compression assembly 4, and the near-infrared spectrum sensor 6 can be embedded in the compression assembly 4 or installed on one side of the compression assembly 4. The emission end and the receiving end of the near-infrared spectrum sensor 6 are directed toward the puncture point. The near-infrared spectrum sensor 6 is used to emit a near-infrared light beam to the wrist puncture point of the human body and receive the near-infrared light beam returned from the puncture point. During operation, the near-infrared spectrum sensor 6 emits a near-infrared light beam of a specific wave band to the wrist puncture point and the subcutaneous tissue. The near-infrared light beam penetrates the skin, part of which is absorbed by hemoglobin in the tissue and part of which is reflected back. The receiving end of the near-infrared spectrum sensor 6 receives the near-infrared light beam reflected from the deep subcutaneous tissue and converts the optical signal into an electrical signal. Since hemoglobin can absorb a near-infrared light beam of a specific wavelength, by analyzing the spectral characteristics of the returned light beam (for example, the change in the absorption of the near-infrared light beam of a specific wavelength by hemoglobin), the hemostasis condition at the deep puncture point and whether there is a tendency to form a hematoma can be evaluated. That is, if the absorption rate of the near-infrared light beam of a specific wavelength by hemoglobin gradually rises, it indicates that the compression force is insufficient, blood accumulates at the puncture point, and there is a risk of hematoma. If the absorption rate of the near-infrared light beam of a specific wavelength by hemoglobin gradually decreases, it indicates that the compression force is too large, the blood begins to coagulate, and the radial artery may be occluded.

[0046] Based on the pressure sensor 5, the near-infrared spectrum sensor 6 and the driving mechanism 3 are all electrically connected with the control system 7, which can be a microcontroller installed on the support base 1, and the control system 7 is internally preconfigured with a control algorithm, and the signal output ends of the pressure sensor 5 and the near-infrared spectrum sensor 6, and the control input end (for example, the motor 301) of the driving mechanism 3 are all electrically connected with the control system 7 through wires or in a wireless manner; as a preferred design, the control system 7 is provided with a display screen, on which the pressure value measured by the pressure sensor 5 and the spectrum change data information can be displayed; based on the control system 7 for controlling the movement of the driving mechanism 3 according to the feedback signal of the near-infrared spectrum sensor 6, the control system 7 continuously receives the real-time pressure data from the pressure sensor 5 and the spectrum feedback signal from the near-infrared spectrum sensor 6.

[0047] The working process is as follows: the patient's wrist passes through the connecting channel formed by the flexible connecting component 2 and the support base 1, tightens the flexible connecting component 2, fixes the whole device on the wrist and aligns the compression assembly 4 to the puncture point, and then the control system 7 controls the lifting part of the driving mechanism 3 to drive the compression assembly 4 to descend and compress the skin of the puncture point, and the compression force is gradually increased, at this time the pressure sensor 5 monitors the compression force in real time and transmits it to the control system 7, and the near-infrared spectrum sensor 6 emits a near-infrared light beam to the puncture point, analyzes the bleeding condition of the subcutaneous tissue in real time by receiving the reflected light, and the algorithm in the control system 7 comprehensively analyzes the two groups of signals: when the absorption change rate of hemoglobin to the near-infrared light beam of a specific wavelength tends to be stable, it indicates that the bleeding stops, at this time the pressure recorded in the pressure sensor 5 is the initial pressure, the control system 7 controls the driving mechanism 3 to stop descending, and the compression assembly 4 maintains a stable compression force on the skin of the puncture point, thereby realizing rapid hemostasis.

[0048] After a period of time, the puncture point starts to clot, the absorption rate of hemoglobin to the near-infrared light beam of a specific wavelength gradually decreases, the control system 7 controls the driving mechanism 3 to rise, thereby driving the compression assembly 4 to rise and gradually reduce the compression force applied to the puncture point, and when the absorption change rate of hemoglobin to the near-infrared light beam of a specific wavelength tends to be stable again, the control system 7 controls the driving mechanism 3 to stop descending again, and the compression assembly 4 maintains a stable compression force on the skin of the puncture point. It can be understood that according to the feedback signals of the pressure sensor 5 and the near-infrared spectrum sensor 6, on the one hand, real-time pressure detection of the compression assembly 4 compressing the skin of the puncture point is realized; on the other hand, the control system 7 controls the driving mechanism 3 to rise multiple times, so that the compression force can be changed in time according to the clotting state of the patient, so that the compression assembly 4 can always compress the skin of the puncture point with a suitable pressure, which can realize rapid hemostasis and avoid the occlusion of the radial artery caused by untimely decompression.

The bottom of the compression plate 402 is used for compressing the human wrist puncture point; the compression plate 402 is provided with a first light transmission structure 4021, the first light transmission structure 4021 is used for the near-infrared light beam emitted by the near-infrared spectrum sensor 6 to penetrate and irradiate to the human wrist puncture point, it can be understood that in order to improve the reliability of the monitoring data, in the area of the compression plate 402 directly opposite to the lower puncture point, the first light transmission structure 4021 made of a high-transmittance material (for example, medical polycarbonate) is adopted, the first light transmission structure 4021 is a light transmission plate installed on the through hole of the compression plate 402, the emission end of the near-infrared spectrum sensor 6 vertically downward emits a light beam, which penetrates through the first light transmission structure 4021 and directly irradiates to the skin surface and penetrates into the subcutaneous tissue.

[0052] The compression column 401 is inserted into the positioning hole 4022, and the near-infrared spectrum sensor 6 is accommodated in the second accommodating space 4023, so that the first light-transmitting structure 4021, the second accommodating space 4023 and the second light-transmitting structure 4012 jointly form a light-transmitting channel. In use, the lower end of the compression column 401 is inserted into the positioning hole 4022 of the compression plate 402, so that the first light-transmitting structure 4021 is aligned with the second light-transmitting structure 4012.

[0057] After the compression column 401 is inserted into the compression plate 402, before formal use, the first light-transmitting structure 4021 and the second light-transmitting structure 4012 need to be cleaned. The medical staff can simultaneously or sequentially pull out a plurality of pull ropes 902 outside the compression plate 402. The pull rope 902 pulls and tears the dust removal piece 901, so that the dust removal piece 901 moves in the second containing space 4023 away from the axis of the compression plate 402. A plurality of dust removal piece 901 fragments wipe and clean the optical surfaces of the first light-transmitting structure 4021 and the second light-transmitting structure 4012 respectively during the movement, avoiding scattering of the light beam due to contact with dust, and further improving the accuracy of the monitoring data of the near-infrared spectrum sensor 6. In addition, the movement of the pull rope 902 drives the dust removal piece 901 to push the corresponding sealing lip 8, so that the sealing lip 8 rotates around the hinge shaft, so that the sealing lip 8 end is engaged in the annular limiting groove 4024, and the locking of the compression column 401 and the compression plate 402 is initially realized.

[0058] As shown in Figures 1-4 , preferably, the dust removal piece 901 is provided with a convenient tearing structure 9011. It can be understood that the convenient tearing structure 9011 is a tear line, which facilitates tearing the dust removal piece 901 into a plurality of specific pieces when the medical staff pulls the pull rope 902, so that each dust removal piece 901 can push one sealing lip 8 to engage in the annular limiting groove 4024.

[0059] As shown in Figures 1-3 , preferably, the side wall of the compression plate 402 is provided with a hook 10, and the hook 10 has a plurality of pull ropes 902, each of which is wound on one of the hooks 10 to lock a plurality of sealing lips 8 in the annular limiting groove 4024. After the sealing lip 8 is engaged in the annular limiting groove 4024, each pull rope 902 is wound on the corresponding hook 10, thereby resisting the rebound of the sealing lip 8 under the action of gravity, avoiding the sealing lip 8 from disengaging from the annular limiting groove 4024, and ensuring the cooperation of the compression column 401 and the compression plate 402 by locking the sealing lip 8 in the annular limiting groove 4024.

[0060] As shown in Figure 1 , Figure 4 and Figure 5 , preferably, the compression plate 402 is provided with a ventilation pipe 4025 which communicates with the external environment; the plate body of the compression plate 402 is processed with a ventilation pipe 4025 which communicates with the external environment through a standard interface.

[0061] The compression assembly 4 further comprises a ring-shaped air bag 403 arranged on the compression plate 402 and around the bottom of the compression plate 402, the ring-shaped air bag 403 being in communication with the air passage 4025. The ring-shaped air bag 403 is made of elastic film material (such as medical silicone or TPU), and is fixedly attached to the bottom surface of the compression plate 402 for contacting the skin of the wrist. After the medical staff ventilates the air passage 4025 with a needle tube, the ring-shaped air bag 403 expands, and the expanded ring-shaped air bag 403 exerts a compression force on the skin tissue around the puncture point, which is lower than the compression force at the puncture point. Compared with the rigid compression of the compression plate 402, the compression of the ring-shaped air bag 403 to some extent relieves the blood circulation resistance of the tissue around the puncture point, is conducive to maintaining the blood oxygen supply of the local tissue, and is conducive to improving the hemostasis rate.

[0062] As shown in Figure 2 Preferably, the driving mechanism 3 comprises a motor 301, a lead screw 302 and a sliding block 303, the motor 301 is drivingly connected with the lead screw 302, the sliding block 303 is movably sleeved on the periphery of the lead screw 302 and can move up and down along the length direction of the lead screw 302, and the sliding block 303 is connected with the compression column 401 in linkage to drive the compression column 401 to move up and down. It can be understood that the motor 301 is a driving part of the driving mechanism 3, and the sliding block 303 is a lifting part of the driving mechanism 3. When the motor 301 rotates forward or reversely under the instruction of the control system 7, it can drive the lead screw 302 to rotate, thereby driving the sliding block 303 to move up or down along the axial direction of the lead screw 302 (i.e. the direction of gravity). Based on the abutment of the sliding block 303 against the pressure sensor 5, when the sliding block 303 moves downward to drive the compression column 401 and the compression plate 402 to apply a compression force to the skin of the puncture point, the compression force is reflected as the pressure of the sliding block 303 against the pressure sensor 5.
