Abstract
Description
Technical Field
[0001] This invention relates to the field of medical care technology, specifically to an arterial compression hemostasis device that can monitor pressure. Background Technology
[0002] Existing hemostatic devices use the principle of spring compression, and the tightness and pressure can be adjusted by adjusting the strap and the cap.
[0003] However, this type of hemostatic device has the following disadvantages and deficiencies:
[0004] The lack of a quantifiable pressure standard leads to inconsistent hemostatic effects: Existing arterial compression hemostatic devices rely on the principle of spring compression, adjusting the tightness through a strap and a rotating cap, but they lack a pressure quantification mechanism and specific pressure values for reference. Medical staff can only rely on subjective experience to judge the tightness, resulting in varying compression pressures from person to person and from operation to operation. This makes it difficult to better match the minimum effective pressure required for hemostasis, easily leading to problems such as "too loose and ineffective, too tight and damaging."
[0005] Lack of personalized adaptation capability to patients with different coagulation functions: Different patients have different coagulation functions and vascular conditions (e.g., patients with coagulation dysfunction need lower pressure, while patients with postoperative hypercoagulable state need moderate pressure). However, existing devices do not have a basis for differentiated pressure adjustment and can only adopt a uniform "empirical pressure" mode. They cannot develop personalized compression plans for individual patients, which increases the risk of hemostasis failure or tissue damage.
[0006] The lack of safety monitoring can easily lead to complications: Existing devices cannot provide real-time feedback on the pressure. When the pressure is too tight, medical staff may not be able to detect it in time, which can lead to slowed blood circulation in the hands, resulting in adverse reactions such as decreased skin temperature, darkening of skin color, swelling, numbness, and pain in the hands. In severe cases, it may cause local tissue ischemia and hypoxia, affecting limb function.
[0007] The operation relies on subjective experience and has a low margin for error: the adjustment of the pressure depends entirely on the feel and experience of medical staff. When novice nurses or those who are not skilled in the operation are not proficient, it is difficult to control the pressure well. Insufficient pressure may lead to uncontrollable arterial bleeding, while excessive pressure may cause unnecessary tissue damage. To address this, the present invention provides an arterial compression hemostasis device that can monitor pressure. Summary of the Invention

[0019] Beneficial effects

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1-4 An arterial compression hemostasis device capable of monitoring pressure includes: a compression hemostat 1, a pressure sensing chip 2, a pressure display dial 3, a pressurizing mechanism 4, and a database 5; the pressure sensing chip 2 is disposed in the inner area of the compression hemostat 1 in contact with the patient's skin, for pressure acquisition; the pressure sensing chip 2 senses the pressure between the skin and the compression hemostat 1 in real time, and converts the physical pressure signal into a recognizable electrical signal, providing a data basis for pressure quantification.
[0033] The pressure display dial 3 is located on the outer surface of the compression hemostat 1, and is connected to the pressure sensing chip 2 via built-in wiring. It displays the pressure collected by the pressure sensing chip 2. The pressure display dial 3 converts the electrical signal transmitted by the pressure sensing chip 2 into a specific pressure value (unit: mmHg or kPa), displaying the current compression pressure in real time. This allows medical staff to intuitively grasp the pressure level, replacing traditional "subjective judgment." Through the real-time display of the pressure value, medical staff can check at any time whether the pressure is within the safe range: when the value is below the effective hemostasis threshold, tighten the cap 42 to replenish pressure and avoid hemostasis failure; when the value is above the safe upper limit, immediately loosen the strap 41 to relieve pressure and prevent obstruction of blood circulation in the hand, thus reducing the occurrence of complications such as skin darkening, swelling, and numbness.
[0034] The pressure sensor chip 2 and the pressure display dial 3 work together to convert the compression pressure into an intuitive value, which medical staff can use to make better adjustments according to the standard, thus standardizing the hemostasis operation and significantly reducing the hemostasis failure rate.
[0035] The pressure mechanism 4 includes straps 41 installed at both ends of the compression hemostat 1 and a rotating cap 42 located on the outside of the compression hemostat 1. The straps 41 are used to wrap around the patient's limb to fix the compression hemostat 1 to the corresponding body surface position. The rotating cap 42 is connected to the body of the compression hemostat 1 through a threaded structure. The rotating cap 42 is used to drive the pressure sensing chip 2 to apply or adjust pressure towards the skin. The device is initially secured by wrapping the limb with the strap 41, ensuring that the compression hemostat 1 adheres to the target body surface without shifting. Then, by rotating the cap 42, the pressure sensing chip 2 is slowly applied towards the skin, while the real-time value on the pressure display dial 3 is observed until the effective threshold for hemostasis is reached (such as a personalized value set according to the patient's age and artery location). This combined approach ensures the stability of the device fixation and achieves better controllability of pressure adjustment. Combined with the real-time data acquisition from the pressure sensing chip 2 and the intuitive feedback from the display dial 3, the entire pressurization process is based on data. Medical staff do not need to relearn complex operations; they only need to refer to the dial values based on their existing operations. This reduces the learning cost for clinical promotion, avoids the blindness of adjusting based solely on experience in traditional operations, and further improves the safety and standardization of hemostasis operations.
[0036] Database 5 establishes a data connection with pressure sensing chip 2 and pressure display dial 3 via a low-power Bluetooth module. Medical staff can adjust the pressure value displayed on the pressure display dial 3 to better suit the patient's individual range by adjusting the strap 41 and the rotating cap 42, based on the patient's coagulation function test results and vascular condition, and referring to reference standards, thus avoiding a "one-size-fits-all" pressure application. A "patient individual characteristics - pressure range" correspondence system is established based on the pressure value, allowing medical staff to better adjust the pressure in conjunction with coagulation reports, achieving "one pressure per patient" and reducing the incidence of complications caused by pressure mismatch.
[0037] Specifically, the pressure sensing chip 2 uses a flexible, biocompatible sensing material. This flexible, biocompatible material has excellent skin-fitting properties, conforming to the natural curves of the patient's limbs and adhering tightly to the skin surface. This avoids uneven local pressure or blind spots caused by material rigidity, ensuring the continuity and accuracy of pressure signal acquisition. Furthermore, its excellent biocompatibility effectively reduces the risk of adverse contact reactions such as skin allergies, redness, and itching, ensuring patient comfort and safety even during prolonged wear. It also possesses a certain degree of bending and tensile strength, adapting to the deformation requirements during strap fixation and cap adjustment, and is less prone to cracking or sensor performance degradation. Simultaneously, it is compatible with commonly used medical disinfection methods (such as 75% alcohol wiping and ultraviolet disinfection), facilitating repeated clinical use and reducing equipment maintenance costs.
[0038] Specifically, the pressure display dial 3 uses a high-contrast LCD screen and is equipped with a wear-resistant and scratch-resistant tempered glass cover to ensure that real-time pressure values can be clearly read under different lighting conditions, such as indoor lighting and outdoor natural light. The pressure display dial 3 also has a built-in micro low-power lithium battery, which can support continuous display for more than 72 hours on a single charge. It also has a power reminder function, which will flash when the power is below 10% to ensure the continuous and stable operation of the device during hemostasis monitoring.
[0039] Specifically, the pressure display dial 3 has three-color warning indicators: red, green, and yellow. Red indicates pressure above the effective pressure, green indicates pressure within the safe range, and yellow indicates pressure below the effective pressure, further enhancing operational safety.
[0040] Specifically, the bandage 41 is made of medical-grade elastic breathable fabric. This fabric has excellent elasticity and stretchability, adapting to the varying limb sizes of different patients. While ensuring the stability of the compression hemostat, it avoids problems such as poor local blood circulation due to overly tight bandages or device displacement due to overly loose bandages. The ventilation holes effectively promote airflow over the skin, reducing sweat buildup and lowering the probability of skin maceration, folliculitis, and other problems caused by prolonged wear. The surface of the bandage 41 is sewn with wear-resistant Velcro. This Velcro allows for quick opening and closing of the bandage and fine-tuning of its tightness. Medical staff or patients can flexibly adjust the attachment position based on limb size and pressure monitoring data during hemostasis, ensuring that the pressure is maintained within a suitable range that effectively stops bleeding without hindering local blood circulation.
[0041] Specifically, the rotating cap 42 is injection molded from medical-grade ABS plastic. Medical-grade ABS plastic has excellent mechanical strength and impact resistance, and can withstand frequent rotation and adjustment operations in clinical settings without easily deforming or breaking, ensuring structural stability for long-term use. In addition, medical-grade ABS plastic has good chemical corrosion resistance and can withstand repeated wiping with commonly used medical disinfectants such as 75% alcohol and chlorine-containing disinfectants. It is also not prone to yellowing or aging, extending the service life of the device. The surface of the compression hemostat 1 is provided with a threaded hole, and the inner end of the cap 42 is provided with a threaded post that is threadedly connected to the threaded hole. With the cooperation of the threaded hole and the threaded post, the cap 42 can be rotated smoothly and moved linearly, ensuring that the pressure applied by the pressure sensing chip 2 towards the skin increases or decreases evenly, avoiding local discomfort or fluctuations in hemostasis effect caused by sudden pressure changes. In addition, the threaded structure has good self-locking performance, which can prevent the cap from being accidentally loosened due to external forces such as patient limb movement or slight touch during hemostasis, maintaining the stability of the set pressure, and further ensuring the continuity and reliability of the hemostasis effect. In addition, the threaded mating part is treated with a medical-grade lubricating coating to reduce frictional resistance during rotation adjustment, making the operation smoother and less strenuous. Even with long-term and frequent use, it is not easy to jam, improving the operating experience and adjustment efficiency of medical staff.
[0042] Specifically, Database 5 incorporates clinical data and includes a dataset of standard pressure thresholds for arterial hemostasis covering different limbs in adults and children, establishing pressure reference ranges for different scenarios and patient groups; thus enabling personalized adaptation to meet the needs of different patients.
[0043] Specifically, it also includes: terminal device 6, which is a smartphone, tablet computer or dedicated medical monitoring terminal, and achieves two-way data interaction with database 5 and pressure display dial 3 through a low-power Bluetooth module; under the action of terminal device 6, it can receive and store continuous pressure data transmitted by pressure display dial 3 in real time, forming a complete pressure change curve of the patient's hemostasis process, which is convenient for medical staff to retrospectively analyze the standardization of hemostasis operation and the rationality of pressure adjustment, and provide data support for optimizing personalized hemostasis plan.
[0044] Specifically, it also includes: a data recording unit 7, which establishes a stable connection with the pressure sensing chip 2, the database 5 and the terminal device 6 through an internal high-speed data bus; under the action of the data recording unit 7, it can record in real time the continuous pressure values transmitted by the pressure sensing chip 2, the timestamp of the adjustment operation of the pressurizing mechanism 4 and the corresponding pressure change amplitude, and synchronize these structured data to the database 5 and the terminal device 6.
[0045] Specifically, the data recording unit 7 includes: a data storage module 71, a timestamp marking module 72, an abnormal data filtering module 73, and a data export interface 74. The data storage module 71 uses an embedded flash memory chip with a capacity of at least 8GB. The timestamp marking module 72 adds a timestamp accurate to milliseconds to each piece of collected pressure data to ensure the time traceability of the data. The abnormal data filtering module 73 calls the standard pressure threshold dataset in the database 5 in real time, compares the collected pressure data with the corresponding thresholds, automatically marks abnormal data exceeding the safe range, and generates an abnormal event log containing the abnormal time, abnormal pressure value, and duration. The data export interface 74 uses USB-C wired transmission and low-power Bluetooth wireless transmission to export the stored historical data in batches to the terminal device 6 or the hospital's electronic medical record system. With the cooperation of data storage module 71, timestamp marking module 72, abnormal data filtering module 73, and data export interface 74, better management of pressure data throughout the entire hemostasis process can be achieved. From pressure signal acquisition and timestamp marking to abnormal identification, data storage, and export, each module works in concert to ensure the integrity, time traceability, and accuracy of each pressure data point, while also capturing abnormal pressure events exceeding thresholds in real time and forming traceable log records. Medical staff can quickly obtain the complete data archive of the patient during hemostasis through data export interface 74, and combine it with abnormal event logs to deeply analyze the rationality of pressure regulation, better locate potential risk points in the operation, and provide a scientific basis for optimizing subsequent personalized hemostasis plans.
[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0047] Working principle:
[0048] In use, first apply the compression hemostat 1 to the target artery on the patient's body surface, then wrap the limb with the strap 41 and quickly secure it with wear-resistant Velcro to ensure a stable and non-shifting fit. Next, rotate the cap 42 to drive the pressure sensor chip 2 to apply pressure smoothly towards the skin through the threaded structure. At the same time, observe the real-time value and three-color warning indicator on the pressure display dial 3: when the value is below the effective threshold, it will display yellow, indicating that the cap 42 needs to be tightened to supplement the pressure; when the value is within the safe range, it will display green, indicating that the appropriate hemostatic pressure has been reached; if the value is above the safe upper limit, it will display red, and the strap 41 should be loosened immediately or the cap 42 should be rotated in the opposite direction to relieve pressure.
[0049] The pressure sensing chip 2 continuously collects pressure signals between the skin and the device, converts the physical signals into electrical signals, and transmits them to the pressure display dial 3 via built-in circuitry, achieving quantitative visualization of the pressure. Simultaneously, the pressure sensing chip 2 connects to the database 5 and the terminal device 6 via Bluetooth Low Energy. The database 5 contains a dataset of standard threshold values for arterial hemostasis in different limbs for adults and children, providing a reference for personalized pressure adjustment. Medical staff can accurately adjust the pressure to a "one-person-one-pressure" suitable range by considering the patient's coagulation function and vascular condition, and referring to the threshold values in the database 5. The terminal device 6 receives and stores continuous pressure data in real time, forming a complete pressure change curve of the hemostasis process. The data recording unit 7 adds a millisecond-level timestamp to each pressure data point, and the abnormal data filtering module 73 compares the data with the threshold values in the database 5, marking out-of-range data, generating an abnormal event log. The structured data can be exported to the hospital's electronic medical record system via the data export interface 74.
[0050] Throughout the process, the threaded self-locking feature of the pressurizing mechanism 4 prevents accidental loosening of the pressure, the low-power lithium battery of the pressure display dial 3 ensures continuous operation, and the flexible material of the pressure sensing chip 2 ensures accurate data collection and patient comfort. The components work together to achieve standardization, visualization, and traceability of hemostasis operations, effectively reducing the hemostasis failure rate and the risk of complications.
