Description

Technical Field

[0001] The embodiments of the present application relate to the field of smart medical care, and more specifically, the present invention relates to a method for monitoring hemostasis after arterial puncture and related equipment. Background Art

[0002] The time and strength of compression for hemostasis after arterial puncture are relatively high. The arterial pressure is high and the healing speed of the puncture point is relatively slow. Therefore, a long period of compression is required, at least five minutes, to ensure successful hemostasis. Some patients need 10 minutes or half an hour, which is extremely labor-intensive for nursing. At the same time, there are also requirements for compression technology. Excessive compression may cause local tissue ischemia and even affect the blood circulation of the limbs; too little force may not effectively stop bleeding, resulting in hematoma or bleeding. After arterial puncture, nursing staff need to manually continue to compress hemostasis and judge the hemostasis effect in real time. This not only greatly consumes the time of nursing staff, but also increases the uncertainty in manual operation. Differences in operating techniques and experience of different nursing staff may also lead to different compression effects, further affecting the safety of postoperative hemostasis.

[0041] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0042] In order to solve the problem that the traditional manual compression method is not only time-consuming and labor-intensive, but also prone to poor hemostasis due to improper operation, please refer to Figure 1 , is a flow chart of a method for monitoring hemostasis after arterial puncture provided in an embodiment of the present application, which may specifically include: steps S110 to S130.

[0043] S110, using a sensor to monitor blood flow data at the puncture site of the patient, wherein the blood flow data includes arterial blood flow data and tissue microblood flow data.

[0044] S120, evaluating the hemostatic effect and local tissue ischemia condition of the patient's puncture site based on the venous blood flow data and tissue microblood flow data.

[0045] S130, adjusting the hemostatic pressure according to the hemostatic effect and the local tissue ischemia condition.

[0046] It is understandable that the method uses arterial blood flow monitoring sensors to monitor the blood flow in the arterial vessels to ensure the hemostasis effect after compression. This type of sensor mainly detects the blood flow velocity and direction of the artery at the puncture site to help determine whether the puncture point has successfully stopped bleeding. And tissue micro-blood flow monitoring sensors to detect the microcirculation status in local tissues to ensure that local tissue ischemia is not caused during the hemostasis process. Micro-blood flow monitoring reflects the blood flow rate and blood oxygen saturation in the subcutaneous capillaries, which helps to determine whether the compression is excessive. By combining these two types of data, the system can comprehensively evaluate the hemostasis effect and tissue health. The process of dynamically adjusting the hemostasis pressure is achieved through a closed-loop feedback control mechanism, that is, when the blood flow monitoring signal shows that hemostasis is complete and there is no risk of ischemia in the tissue, the compression force is maintained or reduced; when the blood flow monitoring shows rebleeding or tissue ischemia, the pressure is automatically adjusted to achieve an ideal hemostasis state.

[0047] Exemplarily, arterial blood flow monitoring is usually performed using a Doppler ultrasound sensor or other optical blood flow monitor. The sensors are placed upstream (toward the heart) and downstream (away from the heart) of the arterial puncture point. The system obtains the blood flow velocity and direction in the artery. A slowdown or stop in the blood flow velocity indicates successful hemostasis, whereas a slowdown indicates insufficient compression. For example, after a radial artery puncture, the nurse places a Doppler ultrasound probe near the radial artery puncture point to observe the arterial blood flow waveform in real time. When the waveform disappears during compression, it means that the blood flow has been completely blocked and hemostasis is successful.

[0048] Exemplarily, microblood flow monitoring is usually performed by an optical sensor (such as a laser Doppler flowmeter or a skin spectrometer), which is attached to the skin near the puncture site to measure local tissue microcirculation. The blood flow velocity and blood oxygen saturation data of the local subcutaneous capillaries are obtained. If the data reflects a significant slowdown in blood flow or a decrease in blood oxygen saturation, it means that the pressure is too large and may cause local ischemia. For example, after radial artery puncture, an optical sensor is attached to the skin at the puncture site to monitor the blood oxygen saturation of the local skin in real time. When it is detected that the skin blood oxygen drops to a certain threshold after compression, the system automatically issues an alarm to remind the caregiver to adjust the pressure to avoid tissue ischemia.

[0049] Exemplarily, the system fuses data from arterial blood flow sensors and micro blood flow sensors. Arterial blood flow data is used to determine whether hemostasis is completed, while micro blood flow data is used to evaluate whether compression causes local tissue ischemia. Based on these data, the system can determine whether the current compression state is reasonable. If the arterial blood flow has stopped but the micro blood flow is normal, it indicates that the compression effect is good. If the arterial blood flow stops but the micro blood flow slows down significantly, it indicates that the compression may be too large and the pressure needs to be reduced; if the arterial blood flow is not completely blocked, it indicates that the compression force is insufficient and pressure needs to be increased. Based on the above evaluation results, the system dynamically adjusts the compression force through a built-in feedback mechanism to ensure the best hemostasis effect. Specifically, the compression device can be a mechanical control system or an airbag that can automatically increase or decrease the compression force based on the data fed back by the sensor. When the arterial blood flow detects signs of bleeding, the system automatically increases the pressure; when the micro blood flow detects the risk of ischemia, the system reduces the pressure to ensure the blood supply of the local tissue.

[0050] It is understandable that by real-time monitoring of arterial blood flow, the system can effectively determine whether the hemostasis effect has been achieved and avoid the risk of rebleeding due to insufficient compression. By monitoring microblood flow data, local tissue ischemia caused by excessive compression can be avoided, thereby ensuring the health of patients' postoperative tissues and reducing complications. By combining arterial blood flow and microblood flow data, the system can achieve more accurate evaluations, avoid misjudgments caused by single data, and ensure the dual goals of hemostasis and tissue health. By automatically adjusting the compression intensity, the system can dynamically respond to individual differences among different patients, avoid the uncertainty of human judgment, and thus improve the overall quality of care and patient comfort.

[0051] In summary, the method for monitoring hemostasis after arterial puncture provided in the embodiment of the present application uses a sensor to monitor the blood flow data of the patient's puncture site, and the blood flow data includes arterial blood flow data and tissue microblood flow data; based on the arterial blood flow data and tissue microblood flow data, the hemostatic effect and local tissue ischemia of the patient's puncture site are evaluated; and the hemostatic pressure is adjusted according to the hemostatic effect and local tissue ischemia. Through precise arterial blood flow monitoring and compression force control, the occurrence of rebleeding can be significantly reduced. Through the automated adjustment system, nursing staff no longer need to continuously monitor the compression process, thereby improving work efficiency. By introducing microblood flow monitoring, local tissue ischemia caused by excessive compression can be effectively prevented, and the risk of tissue damage can be reduced. Based on real-time data feedback, the system can dynamically adjust the pressure to adapt to the individual differences of different patients and provide a more refined nursing plan.

[0052] According to some embodiments, the arterial blood flow data includes arterial blood flow velocity and direction, and evaluating the hemostatic effect of the patient's puncture site based on the arterial blood flow data includes:

[0053] The hemostatic effect at the patient's puncture site is evaluated based on the arterial blood flow velocity and direction.

[0054] It is understandable that arterial blood flow velocity is a key indicator for judging the hemostasis effect at the puncture site. During the compression hemostasis process, if the blood flow velocity slows down significantly or even stops completely, it indicates that the compression is effective and the hemostasis is successful. On the contrary, if the blood flow velocity remains at a high level or persists, it means that the compression force is insufficient and the hemostasis may not be effective.

[0055] Exemplarily, the sensor monitors the blood flow velocity at the arterial puncture site in real time, and the system compares the collected blood flow velocity with the preset normal range. When the blood flow velocity drops to close to zero, it means that the artery has been successfully compressed and the hemostasis effect is ideal. For example, after radial artery puncture, the sensor monitors that the blood flow velocity at the puncture site gradually drops to close to zero, and it can be inferred that compression hemostasis is successful. If the blood flow velocity is still fast after a period of compression, the compression force needs to be increased to stop the arterial blood flow.

[0056] It is understandable that in addition to blood flow velocity, arterial blood flow direction is also an important evaluation parameter. Arterial blood flow usually has a certain directionality. If the compression is insufficient or incomplete, the blood flow direction may change abnormally, such as generating reverse flow or dispersed lateral flow. By monitoring abnormal changes in blood flow direction, it can be further confirmed whether compression has successfully controlled blood flow.

[0057] Exemplarily, the sensor captures the direction of blood flow in the artery, usually detected by Doppler ultrasound. If there is reverse flow or abnormal flow in the direction of blood flow, it may indicate that the puncture site is not completely compressed and the compression needs to be increased. If the blood flow direction remains normal but the blood flow rate slows down significantly, it indicates that the hemostasis effect is better. For example, after femoral artery puncture, the sensor detects abnormal changes in the direction of blood flow near the puncture site, such as reverse flow, indicating that the puncture point is not fully controlled, the compression is insufficient, and further strengthening of hemostasis measures is required.

[0058] It is understandable that the system combines the arterial blood flow velocity and direction for comprehensive analysis. If the blood flow velocity gradually slows down and the direction remains normal, it indicates that the hemostasis process is going smoothly. If the velocity remains unchanged or the direction is abnormal, the compression pressure needs to be adjusted according to the situation. Through real-time feedback of arterial blood flow monitoring data, the system can automatically determine the current hemostasis status and prompt the nursing staff whether they need to continue to adjust the compression pressure, or dynamically adjust the compression force by the automatic adjustment device. By real-time monitoring of arterial blood flow velocity and direction, this method can accurately evaluate the hemostasis effect of the puncture site and provide early warning of rebleeding or insufficient compression. Nursing staff or automated systems can make timely adjustments based on these data to ensure the best hemostasis effect after puncture while avoiding the risk of rebleeding.

[0059] In some examples, the tissue microblood flow data includes a microblood flow rate, and assessing a local tissue ischemia condition at a puncture site of a patient based on the tissue microblood flow data includes:

[0060] The local tissue ischemia situation at the puncture site of the patient is evaluated based on the microblood flow rate.

[0061] It is understandable that the micro blood flow rate reflects the blood flow in the capillary network in the local tissue. Under normal circumstances, the micro blood flow rate in the tissue is relatively stable and can maintain the nutrient supply and metabolism of the local tissue. If the compression is excessive, it may cause a significant decrease in the local capillary blood flow rate, or even tissue ischemia, leading to skin or deep tissue damage. Therefore, changes in the micro blood flow rate can be used as a key indicator for judging local tissue ischemia.

[0062] Exemplarily, the system monitors the microblood flow rate of the tissue around the puncture site in real time through an optical sensor or a laser Doppler flowmeter. If the microblood flow rate drops below a certain threshold, the system will determine that local tissue may be ischemic and prompt the caregiver or automatic system to reduce the pressure. The sensor compares the collected microblood flow rate data with the preset normal microblood flow rate. If the microblood flow rate remains within the normal range, it means that the tissue blood supply is normal; if the rate drops significantly, it may mean that the local blood flow is blocked by compression, indicating the risk of ischemia.

[0063] It is understandable that local tissue ischemia usually occurs when compression is excessive. When the compression force exceeds a certain limit, not only is the arterial blood flow blocked, but the blood circulation in the local capillaries is also affected, leading to insufficient blood supply to the tissue. By monitoring the microblood flow rate, early ischemic signals can be detected and the compression force can be adjusted in time to avoid tissue damage.

[0064] For example, when the system detects that the micro blood flow rate drops to a dangerous level (such as reduced to less than 50% of the normal level), the system will issue a warning, indicating that the compression may be too large and may cause insufficient blood supply to local tissues. If the monitoring results show that the micro blood flow rate has not dropped significantly, it means that the compression intensity is within a reasonable range.

[0065] It is understandable that in addition to arterial blood flow data, micro blood flow rate is an important data for assessing the health of local tissues. By fusing these two types of data, the system can more comprehensively judge the health of the puncture site. For example, if the arterial blood flow stops but the micro blood flow rate is still within the normal range, it means that the compression effect is good; if the micro blood flow rate drops significantly, it means that the compression is too large and there is a risk of ischemia. By evaluating the changes in the micro blood flow rate in real time, the system can dynamically adjust the compression force to ensure that it can effectively stop bleeding and avoid local tissue ischemia caused by excessive compression. For example, when the micro blood flow rate is detected to be too low, the system can automatically reduce the compression force and restore blood circulation in the local tissue.

[0066] For example, after radial artery puncture, an optical sensor is placed on the skin around the puncture site to monitor the micro blood flow rate in real time. Assuming that the micro blood flow rate detected by the sensor drops to 30% of the normal level, it indicates that the compression force is too great and there is a risk of local ischemia. The system will prompt the caregiver to reduce the pressure or the automated device to adjust the pressure to restore the micro blood flow rate.

[0067] For example, after femoral artery puncture, the laser Doppler sensor monitors the micro blood flow rate at the puncture site. If the micro blood flow rate remains in the range of 70%-90% after compression, it means that the compression force is appropriate and the local tissue still has a good blood supply. The system will continue to maintain the current compression force. If the micro blood flow rate drops below 50%, it indicates that the compression is too large and needs to be adjusted immediately.

[0068] It is understandable that by monitoring the micro blood flow rate, early warning can be given before local tissue ischemia occurs, and compression can be reduced in time to avoid tissue necrosis or other complications caused by excessive compression. Each patient has different tissue tolerance. By real-time monitoring of the micro blood flow rate, personalized compression adjustment can be achieved to ensure effective hemostasis without placing too much burden on local tissues. This method not only improves the accuracy of hemostasis, but also reduces the subjective judgment of nursing staff on the compression process, reduces the risk and workload of manual intervention, and improves the overall quality of care.

[0069] In some examples, this also includes:

[0070] If abnormal bleeding or hematoma formation is detected at the puncture site, an audible and visual alarm will be issued;

[0071] Send an alarm message to the medical staff associated with the patient.

[0072] It is understandable that abnormal bleeding or hematoma formation is usually caused by improper compression at the arterial puncture site or other related factors. During the compression process, the system can detect signs of bleeding or hematoma early by monitoring the arterial blood flow and microblood flow rate. When the blood flow data or microblood flow data exceeds the normal range, the system identifies it as an abnormal condition. When the arterial blood flow velocity does not drop significantly or the blood flow direction is abnormal, the system determines that hemostasis is unsuccessful or there is a risk of rebleeding. If compression fails to effectively control bleeding, local blood seeps into the tissue gap to form a hematoma, and the microblood flow rate may drop sharply, accompanied by local swelling or increased tissue tension. The system can detect this change.

[0073] For example, if during compression, the system detects that the blood flow rate has not slowed down or the direction is abnormal (such as reverse flow or lateral flow), it indicates that there is a risk of abnormal bleeding. The system will issue an alarm. If the micro blood flow rate drops sharply, especially accompanied by signs such as local swelling, the system can determine that there is a possible hematoma formation.

[0074] It is understandable that when the system detects abnormal bleeding or hematoma formation, it will issue an audible and visual alarm to attract the attention of on-site medical staff. The audible and visual alarm is a fast and intuitive alarm method that can help nursing staff immediately identify problems at the patient's puncture site and take timely measures.

[0075] Exemplarily, the system integrates an audible and visual alarm device, which is usually installed at the patient's bedside or nursing station. Once an abnormal situation occurs, the system will activate the device, sound a high-pitched alarm and flash lights to alert on-site personnel. The intensity of the alarm sound and the flashing frequency of the light can be adjusted according to the severity of the abnormal situation. Minor abnormalities may trigger lower-level alarms, while severe bleeding or hematoma may trigger higher-intensity alarms. For example, after radial artery puncture, the system detects that the arterial blood flow velocity at the puncture site has not decreased as expected, and the microblood flow rate has dropped sharply. The system identifies the risk of rebleeding and potential hematoma formation, and immediately triggers an audible and visual alarm, allowing on-site medical staff to respond quickly and intervene.

[0076] It is understandable that in addition to the on-site sound and light alarms, the system can also send abnormal alarm information to the medical and nursing end (such as the nursing information system of the nurse station or the doctor's mobile device) through digital communication technology. In this way, even if the nursing staff is not at the patient's bedside, they can receive the alarm and respond immediately.

[0077] Exemplarily, the alarm information is sent to the medical end through the built-in network communication module of the system. The alarm message usually includes real-time data of the puncture site, description of abnormal conditions (such as abnormal blood flow velocity, decreased micro-blood flow rate, etc.), and recommended intervention measures. The system can send alarm information through various channels, for example: medical staff can receive alarm information through mobile phones. The alarm information can be automatically uploaded to the hospital's nursing document system, and relevant personnel can view the patient's abnormal data in real time through the workstation. A dedicated nursing mobile terminal application can be used, and the alarm information can also be pushed to the APP of the nursing team members. For example, after femoral artery puncture, the system detects that there is a risk of hematoma formation at the puncture site of the patient, and automatically sends the alarm information to the nursing system of the nurse station. At this time, the monitoring screen of the nurse station will display the patient's detailed abnormal data, and the relevant nursing staff can intervene in time. In addition, the doctor will also receive a notification on his mobile phone so that the doctor can quickly guide or participate in the disposal.

[0078] It is understandable that through arterial blood flow and micro-blood flow monitoring, the system can identify the risk of abnormal bleeding and hematoma formation early, significantly reducing postoperative complications caused by insufficient compression or improper operation. The combination of sound and light alarms and remote alarm messages enables caregivers to respond to abnormal conditions of patients in the first place to avoid delays. The alarm system can not only remind on-site medical staff, but also improve the collaboration efficiency of the nursing team by sending alarm information to the nursing system or the doctor's mobile device. Medical staff can quickly receive the patient's condition, formulate intervention measures in advance, and reduce the delay in information transmission. Through the real-time alarm mechanism, abnormal bleeding and hematoma can be discovered and treated at an early stage to prevent them from developing into serious postoperative complications, such as hematoma enlargement or compression of nerves causing tissue necrosis. Through automated monitoring and alarms, caregivers do not need to continuously monitor the puncture site manually, which greatly reduces manpower requirements and improves work efficiency. This system is particularly helpful in reducing the work pressure of medical staff in the application of long-term postoperative care.

[0079] In some examples, this also includes:

[0080] The blood oxygen saturation of the patient's skin around the puncture site is measured by an optical sensor;

[0081] Assessing the local tissue ischemia at the puncture site of the patient based on the blood oxygen saturation of the skin around the puncture site of the patient;

[0082] The hemostatic pressure is adjusted according to the local tissue ischemia situation.

[0083] It is understood that blood oxygen saturation (SpO2) refers to the ratio of oxygenated hemoglobin to total hemoglobin in the blood, reflecting the oxygen supply to the tissues. Under normal circumstances, the blood oxygen saturation in the skin and tissues is in a stable state. If the pressure is too great, the blood supply to the local tissues is blocked and the blood oxygen saturation will decrease, indicating that there may be a risk of ischemia. Optical sensors can detect the blood oxygen saturation in the skin through spectral analysis.

[0084] Exemplarily, an optical sensor (such as a pulse oximeter or a spectral analysis sensor) is attached to the skin around the puncture site, emitting light of a specific wavelength and detecting the reflected light signal. The sensor calculates the blood oxygen saturation under the skin by analyzing these signals. The sensor can continuously or periodically measure the blood oxygen saturation of the local skin and transmit this data to the system for real-time evaluation. If the blood oxygen saturation is lower than the normal range, the system will issue an alarm. For example, after a femoral artery puncture, an optical sensor is placed on the skin around the patient's puncture site. The sensor measures the local blood oxygen saturation every few minutes. Assuming that the normal blood oxygen saturation is 95%-100%, and the monitored value drops to 85%, it indicates that the local tissue may be ischemic due to excessive compression, and the system will trigger an alarm to alert the caregiver.

[0085] It is understandable that local tissue ischemia is usually accompanied by a decrease in blood oxygen saturation. When the arterial puncture site is compressed, blood flow is blocked. If the compression is too strong, it will not only block arterial blood flow, but also affect the blood supply in the local capillaries, resulting in insufficient tissue oxygen supply. By detecting changes in skin blood oxygen saturation, the ischemic condition of local tissues can be indirectly assessed.

[0086] Exemplarily, the system presets a normal blood oxygen saturation range (usually 95%-100%). When the blood oxygen saturation drops below a certain threshold (such as 90% or 85%), the system will determine that there may be ischemia in the local tissue. The system compares the collected blood oxygen saturation data with the normal value. If it is detected that the blood oxygen saturation continues to decrease, it indicates that the compression force is too great, which may cause tissue ischemia. For example, after radial artery puncture, the optical sensor detects that the patient's blood oxygen saturation at the puncture site gradually decreases from 98% of the normal value to 87%. The system determines that this is due to local blood flow obstruction caused by excessive compression, causing tissue ischemia, so it issues an alarm to remind nursing staff to intervene.

[0087] It is understandable that when local tissue ischemia is detected, the system will prompt the nursing staff to reduce the pressure or automatically adjust the pressure of the hemostatic device through a feedback mechanism to restore the blood supply and oxygen delivery of the tissue. At the same time, the system will continue to monitor the blood oxygen saturation to ensure that the adjusted pressure is within a reasonable range that can stop bleeding without causing ischemia.

[0088] Exemplarily, when the system detects a drop in blood oxygen saturation and issues a warning, the caregiver can gradually reduce the pressure according to the system prompts until the blood oxygen saturation returns to the normal range. If the system is integrated with an automatic hemostasis device, the system can automatically adjust the pressure based on the feedback from the sensor. For example, when the blood oxygen saturation drops below a certain threshold, the system automatically reduces the pressure, restores local blood flow, and ensures normal blood supply to the tissue. For example, after femoral artery puncture, the system detects that the skin oxygen saturation around the puncture site has dropped to 85%, and it is judged that there is a risk of ischemia. The system automatically reduces the pressure of the compression device and reduces the pressure on the puncture site. After a few minutes, the blood oxygen saturation returns to 95%, indicating that the pressure has been adjusted to a reasonable range.

[0089] It is understandable that by real-time monitoring of blood oxygen saturation through optical sensors, the system can sound an alarm in the early stages of local tissue ischemia to prevent tissue damage due to prolonged ischemia. Blood oxygen saturation is a direct sign of ischemia, so this monitoring method is more sensitive and reliable. The system can not only monitor blood oxygen saturation, but also dynamically adjust the compression force according to the risk of ischemia. This ensures that while stopping bleeding, local tissue blood supply is avoided, and tissue necrosis or other complications caused by excessive compression are effectively prevented. By real-time monitoring of each patient's local blood oxygen saturation and adjusting the compression force, the system can provide personalized care based on the individual differences of different patients and reduce the occurrence of compression-related complications. Especially in the elderly or patients with poor vascular conditions, this monitoring can significantly reduce risks. This automated, real-time monitoring and feedback adjustment system reduces the burden on caregivers and improves the quality of care. Caregivers can rely on the system's real-time data to make decisions, without the need to frequently manually adjust the compression force, thereby improving care efficiency.

[0090] In some examples, this also includes:

[0091] Monitor patients’ blood pressure data;

[0092] In the event that there is a change in the blood pressure data, the hemostatic pressure is adjusted based on the patient's blood pressure change.

[0093] It is understandable that the amount of bleeding and the hemostatic effect at the arterial puncture site are directly related to the patient's blood pressure. High blood pressure increases the risk of bleeding because the pressure in the artery is higher and it is easy to break through the compression point; low blood pressure may cause excessive compression and affect the blood flow of local tissues. By monitoring the patient's blood pressure data in real time, it can provide a reference for the adjustment of anti-hemostatic pressure.

[0094] Exemplarily, through an automatic blood pressure monitor (such as a non-invasive blood pressure monitoring device), the system regularly or continuously monitors the patient's blood pressure data, including systolic pressure, diastolic pressure, and mean arterial pressure. The monitor transmits the collected blood pressure data to the system, and the system analyzes the data in real time to determine the impact of blood pressure changes on compression and hemostasis at the puncture site. For example, after femoral artery puncture, the patient's blood pressure gradually rises from 120 / 80mmHg to 150 / 95mmHg. After the system detects an increase in blood pressure, it determines that the pressure in the artery has increased, which may lead to the risk of rebleeding, and then issues a prompt to adjust the compression intensity.

[0095] It is understandable that since blood pressure directly affects the pressure in the arteries, the system can dynamically adjust the compression pressure according to changes in blood pressure. When blood pressure rises, the system needs to increase the compression to offset the high pressure in the arteries and prevent bleeding; and when blood pressure drops, the system can reduce the compression to avoid excessive compression leading to local tissue ischemia.

[0096] Exemplarily, when the system detects that the patient's blood pressure increases or decreases significantly, the system will issue a prompt to the caregiver, suggesting that the hemostatic pressure be manually adjusted according to the blood pressure change. The caregiver can gradually increase or reduce the compression force according to the prompt to maintain an appropriate hemostatic effect. If the system integrates a device that automatically adjusts the compression force, the system can automatically increase or reduce the compression force according to real-time blood pressure data. For example, when the patient's blood pressure increases, the system automatically increases the pressure of the compression device to ensure that the arterial puncture point maintains effective compression; when the blood pressure drops, the system automatically reduces the pressure to prevent excessive compression from causing local tissue ischemia. Suppose the patient's blood pressure suddenly rises to 160 / 100mmHg, and the system detects a significant increase in intra-arterial pressure. To prevent rebleeding, the system automatically or prompts the caregiver to increase the compression pressure. In another case, the patient's blood pressure drops from 120 / 80mmHg to 90 / 60mmHg, and the system detects a drop in intra-arterial pressure. At this time, the compression pressure is reduced to avoid tissue ischemia or local skin damage due to excessive compression.

[0097] It is understandable that by monitoring the patient's blood pressure data in real time, the system can quickly respond to the risks brought by increased blood pressure. When blood pressure rises, the pressure in the artery increases. If the pressure is insufficient, it may cause rebleeding. The system can automatically or manually increase the pressure to ensure that the arterial blood flow is effectively blocked, thereby reducing the occurrence of rebleeding. In the case of a drop in blood pressure, excessive compression may cause insufficient blood supply to local tissues, resulting in complications such as ischemia and necrosis. The system can monitor changes in blood pressure and reduce the pressure in time when blood pressure drops to ensure that the pressure is not excessive, thereby maintaining normal blood supply and health of local tissues. The blood pressure of each patient is different, especially after surgery, the patient's blood pressure may fluctuate significantly. Through real-time monitoring and dynamic adjustment of the pressure, the system can provide personalized care plans according to the actual situation of each patient to ensure hemostasis and tissue health. At the same time, it reduces the manual judgment and operation of blood pressure changes by nursing staff, and improves the accuracy and efficiency of nursing. The automated system can not only improve the quality of nursing, but also significantly reduce the burden on nursing staff. In the traditional manual nursing process, nursing staff need to frequently monitor the patient's blood pressure and manually adjust the pressure, while the systematic automatic monitoring and adjustment function can reduce the work pressure of nursing staff and reduce the risk of human error.

[0098] In some examples, this also includes:

[0099] Periodically acquiring image data of the skin surrounding the site where the hemostatic pressure force is applied;

[0100] analyzing the color change of the skin around the site where the hemostatic pressure force is applied based on the image data;

[0101] Adjusting the hemostatic pressure according to the color change; and / or,

[0102] Periodically obtain the temperature of the skin surrounding the site of hemostatic compression.

[0103] analyzing temperature changes of the skin around the site where the hemostatic pressure force is applied based on the image data;

[0104] The hemostatic pressure is adjusted according to the temperature change.

[0105] It is understood that by using an image acquisition device (such as a camera or an optical scanning device) to regularly capture images of the skin around the compression area, the appearance data of the skin in the area can be obtained. These image data can provide a basis for subsequent skin color analysis and help determine the health status of local tissues.

[0106] Exemplarily, a small camera or sensor mounted on the hemostasis device can periodically capture images of the skin around the compression site. The frequency of image acquisition can be set to every few minutes or hours as needed. The acquired image data is transmitted to the system, which stores it and compares it with previous image data to analyze skin color changes. For example, after radial artery puncture, the system captures skin images around the puncture point every 10 minutes through a camera mounted on the compression device, generating continuous skin appearance data for subsequent analysis.

[0107] Understandably, skin color changes are usually a direct reflection of local tissue blood flow and health. Color changes can indicate whether the tissue has ischemia, congestion, skin damage, and other problems. Under normal circumstances, the skin may turn slightly white after compression, but if the compression is excessive or for too long, the skin may become pale or cyanotic due to ischemia; and when the compression is insufficient, congestion or bleeding may occur. By analyzing the color changes in the image, the system can determine whether the compression is appropriate.

[0108] Exemplarily, the system uses an image processing algorithm to analyze the collected skin images and detect changes in skin color. Common color changes include paleness (indicating ischemia), cyanosis (indicating congestion) or red congestion (indicating insufficient compression). These changes can be identified by spectral analysis, color distribution analysis or image comparison. The system compares the current skin image with the previous image to analyze the color change trend. For example, the system can set a reference value for normal skin color and monitor whether the color change exceeds the preset normal range. If the color change is too large, the system will prompt the caregiver or automatically adjust the compression force. Suppose that after radial artery puncture, the system analyzes that the skin at the patient's compression site gradually changes from light pink to cyanosis. The system will determine that there may be local ischemia or congestion caused by excessive compression, and issue an alarm to prompt the caregiver to reduce pressure.

[0109] It is understandable that changes in skin color reflect the blood flow and health status of tissues, so the system can dynamically adjust the pressure based on the color change data. For example, when the skin becomes pale or cyanotic, it indicates that the pressure may be too great and needs to be reduced; while if the skin becomes red and congested, it may mean that the pressure is insufficient and needs to be increased.

[0110] Exemplarily, when the system detects a change in skin color and issues a prompt, the caregiver can manually adjust the compression force according to the system's suggestions. For example, the caregiver can gradually reduce or increase the compression force until the skin color returns to normal. If the system integrates an automatic compression adjustment function, the system can automatically increase or reduce the compression force according to the change in skin color. For example, when the skin color changes from normal to pale, the system automatically reduces the pressure; when the skin becomes red and congested, the system automatically increases the pressure. For example, after femoral artery puncture, the system detects that the skin is gradually becoming pale through image analysis, and judges that local tissue may be ischemic, and the system automatically reduces the compression force. Subsequently, the skin color returns to normal pink, indicating that the compression force is adjusted to a reasonable range.

[0111] It is understandable that by periodically collecting image data and analyzing skin color changes, the system can identify excessive compression (causing ischemia) or insufficient compression (causing bleeding and congestion) early. Color changes are direct signals of early local tissue blood flow abnormalities, so early warnings can be issued before complications occur to ensure timely intervention. The system adjusts the compression force according to the real-time changes in skin color to make the compression process more dynamic and precise. This ensures that while stopping bleeding, tissue damage caused by excessive compression or rebleeding caused by insufficient compression can be avoided, reducing the occurrence of postoperative complications. The automated image acquisition and analysis system reduces the frequency of manual inspections of compression sites by nursing staff and reduces the work pressure of nursing staff. Image analysis provides a more objective basis for judgment, reduces the errors that may occur during manual observation, and improves the quality of care. The skin color and reaction of different patients may be different. Through image analysis, personalized care can be provided according to the individual situation of each patient to ensure the accuracy of the care plan. For example, the system can set a personalized color change threshold based on the patient's baseline skin color to improve the flexibility and adaptability of compression adjustment.

[0112] Understandably, skin temperature is an important indicator of local blood flow and tissue health. Changes in compression may affect local skin blood flow, which in turn causes temperature changes. For example, when the compression is too great, blood flow is blocked and local temperature may drop; when the compression is insufficient, local congestion may cause the temperature to rise. By periodically acquiring skin temperature, the system can monitor changes in blood flow at the compression site in real time.

[0113] Exemplarily, temperature sensors are installed around the compression device to periodically collect temperature data of the skin around the compression site. These sensors can be non-contact infrared temperature sensors, or adhesive temperature sensors that directly contact the skin for temperature measurement. The frequency of temperature data collection can be set to every few minutes or every hour according to actual needs, depending on the patient's condition and equipment configuration. For example, after femoral artery puncture, the temperature sensor measures the temperature of the skin around the puncture site every 10 minutes. If the system detects that the temperature is gradually decreasing, it indicates that blood flow obstruction may be caused by excessive compression.

[0114] It is understandable that changes in local skin temperature directly reflect the blood flow of the tissue. When the compression force is too great, the blood flow of the arteries and capillaries may be blocked, resulting in insufficient local blood supply and a drop in skin temperature; when the compression is insufficient, it may induce congestion or local inflammatory reactions, leading to an increase in skin temperature. Therefore, temperature changes can be used as a basis for judging whether the compression force is appropriate.

[0115] Exemplarily, the system analyzes the temperature change trend of the local skin based on the periodically acquired temperature data. If the temperature continues to drop, the system may judge that the local blood supply is insufficient and the compression is excessive; while the temperature continues to rise, it may indicate local congestion and insufficient compression. The system can set a normal temperature range and adjust the threshold according to the conditions of different patients. If the temperature changes beyond the normal range, the system will issue an alarm or adjust the compression force according to the set rules. For example, after radial artery puncture, the temperature sensor detects that the temperature of the skin at the puncture site gradually drops from the normal 36.5°C to 35°C. The system analysis believes that there may be a lack of local blood flow, indicating that the compression needs to be reduced to restore normal blood flow.

[0116] It is understandable that changes in skin temperature are an external manifestation of local blood flow and tissue metabolism. By monitoring temperature changes, the system can dynamically adjust the hemostatic pressure to ensure that it can effectively stop bleeding without causing adverse effects on local tissues. When the temperature drops, the system can restore blood flow by reducing the pressure; when the temperature rises, the system can increase the pressure to relieve congestion.

[0117] Exemplarily, when the system detects that the temperature change exceeds the normal range, the caregiver will receive a system prompt and can manually adjust the compression force. For example, when the skin temperature continues to drop, the caregiver can gradually reduce the compression force to restore local blood flow. If the system integrates the function of automatically adjusting the compression force, the system will automatically adjust the compression pressure based on the feedback of the temperature data. For example, when the temperature drops, the system automatically reduces the compression force; when the temperature rises, the system automatically increases the compression force until the temperature returns to normal. For example, after femoral artery puncture, the system detects that the skin temperature at the puncture site continues to drop to 34.5°C, indicating that local blood flow is obstructed. The system automatically reduces the compression force, and the skin temperature gradually returns to 36°C after a few minutes, indicating that the compression force is adjusted to an appropriate level.

[0118] Understandably, skin temperature changes are often early signs of ischemia due to overcompression or congestion due to undercompression. Through periodic monitoring of temperature sensors, the system can detect these problems early and make adjustments to prevent serious complications. By dynamically adjusting the compression force according to temperature changes, the system can effectively prevent ischemia due to overcompression and rebleeding due to undercompression. The detection of temperature changes provides a real-time and accurate feedback mechanism, making compression adjustments more flexible and accurate. Automated temperature monitoring and pressure adjustment reduces the need for caregivers to manually monitor the compression site. Caregivers can rely on real-time data from the system, reducing the number of human interventions and improving care efficiency and accuracy. Each patient has a different baseline skin temperature and blood flow status. Through personalized monitoring of temperature changes, the system can be adjusted according to individual differences of patients, providing more personalized care plans to ensure optimal hemostasis and tissue health.

[0123] In summary, the hemostasis monitoring device after arterial puncture provided in the embodiment of the present application monitors the blood flow data of the patient's puncture site by using a sensor, and the blood flow data includes arterial blood flow data and tissue microblood flow data; based on the arterial blood flow data and tissue microblood flow data, the hemostasis effect and local tissue ischemia of the patient's puncture site are evaluated; and the hemostasis pressure is adjusted according to the hemostasis effect and local tissue ischemia. Through precise arterial blood flow monitoring and compression force control, the occurrence of rebleeding can be significantly reduced. Through the automated adjustment system, nursing staff no longer need to continuously monitor the compression process, thereby improving work efficiency. By introducing microblood flow monitoring, local tissue ischemia caused by excessive compression can be effectively prevented, and the risk of tissue damage can be reduced. Based on real-time data feedback, the system can dynamically adjust the pressure to adapt to the individual differences of different patients and provide a more refined nursing plan.
