Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to an abdominal circumference monitoring belt, system and method for evaluating the prognosis of patients with liver cirrhosis. Background Art

[0002] Cirrhosis is a chronic liver disease caused by various reasons, characterized by the gradual loss of liver structure and function, usually accompanied by hepatocellular necrosis, fibrosis and liver cirrhosis. As cirrhosis progresses, patients often develop a series of complications, one of the most common complications is ascites. Ascites refers to the accumulation of excessive fluid in the abdominal cavity, usually caused by portal hypertension and liver failure caused by cirrhosis. The formation of ascites not only affects the patient's daily life, but may also cause difficulty breathing, gastrointestinal discomfort, and even serious infection, increasing the patient's risk of death. Therefore, ascites monitoring in patients with cirrhosis is an important part of clinical treatment.

[0003] When a patient with cirrhosis develops ascites, the abdomen usually swells significantly, forming a "water belly" phenomenon. Although abdominal distension is a common manifestation of ascites, patients may not be aware of obvious changes in the abdomen. Current methods of monitoring ascites mainly rely on regular medical examinations, such as ultrasound, CT scans, or weight changes. These methods are often performed when patients visit the doctor and cannot achieve real-time ascites monitoring. Because existing monitoring methods cannot provide immediate feedback in patients' daily lives, changes in ascites often miss the best time for intervention, increasing the risk of complications and treatment difficulties for patients.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0026] like Figures 1 to 9 As shown, in a first aspect of the present invention, a waist circumference monitoring belt for use in prognosis assessment of patients with liver cirrhosis is provided.

[0027] The abdominal circumference monitoring belt for the prognosis assessment of patients with liver cirrhosis includes: a base 1, two elastic bands 2, a connecting component 3 and a monitor 4; the monitor 4 is connected to the base 1, and the two elastic bands 2 are fixedly connected to the base 1. The design of the base 1 needs to have a certain flexibility to adapt to the changes in the patient's abdominal shape and ensure the stability of the monitoring belt during use. The two elastic bands 2 are fixedly connected to the base 1, and the ends of the two elastic bands 2 away from the monitor 4 are detachably connected to the connecting component 3. The elastic band 2 should be made of a material with good elasticity to ensure the comfort and adaptability of the patient when wearing it. The design of the elastic band 2 should be able to adapt to the patient's breathing movements and maintain appropriate tension on the patient's abdomen without hindering breathing. The ends of the two elastic bands 2 away from the monitor 4 are detachably connected to the connecting component 3. The material of the elastic band 2 needs to have appropriate elasticity and comfort to ensure the comfort of the patient when wearing it.

[0028] The monitor 4 includes two monitoring components 41 and two monitoring belt bodies 42. The monitor 4 is connected to the base 1, and the two monitoring belt bodies 42 are respectively wound around the two monitoring components 41. The distal ends of the two monitoring belt bodies 42 are respectively connected to the elastic belt 2. The monitoring component 41 is responsible for monitoring the release length of the monitoring belt body 42.

[0029] The monitoring assembly 41 is used to monitor the release length of the monitoring belt body 42 connected thereto. The two ends of each monitoring belt body 42 are respectively connected to the elastic belt 2 and the monitoring assembly 41. The monitoring belt body 42 is released as the elastic belt 2 stretches, and when the abdomen expands, the monitoring belt body 42 moves accordingly.

[0030] When in use, the patient wraps the two elastic bands 2 around the abdomen, ensuring that the elastic bands 2 are close to the surface of the abdomen while maintaining appropriate tension to accommodate the patient's breathing. The distal ends of the two elastic bands 2 are connected to the monitor 4 through the connecting assembly 3. When the abdomen begins to swell due to the accumulation of ascites, the expansion of the abdomen causes the elastic bands 2 to stretch. The stretching of the elastic bands 2 causes the monitoring belt body 42 to be released together, and the monitoring assembly 41 begins to monitor the change in the length of the monitoring belt body 42.

[0031] When the release length of the monitoring belt body 42 reaches or exceeds a preset threshold, it indicates that the abdominal distension is abnormal, indicating excessive ascites. At this time, the monitor 4 sends an alarm to the patient or medical staff through an indicator light, a sound warning or wireless communication to remind the patient to undergo further examination and relevant treatment.

[0032] The abdominal circumference monitoring belt for the prognosis assessment of patients with liver cirrhosis provided by the present invention provides a significant technical effect by combining multiple components such as a base 1, an elastic band 2, and a monitor 4, aiming at the problem that the prior art cannot monitor the change of ascites in real time. First, the base 1 is fixedly connected to the elastic band 2 to ensure the stability of the monitoring belt on the patient's abdomen, and can adapt to the patient's dynamic situation as the abdominal morphology changes, thereby ensuring the accuracy and reliability of the monitoring data. The monitor 4 monitors the release length of the monitoring belt body 42 in real time to reflect the degree of abdominal expansion by working in coordination with two monitoring components 41 and the monitoring belt body 42. The monitoring component 41 can detect the change of ascites in time by sensing the extension of the monitoring belt body 42. When the release length exceeds the set threshold, the system reminds the patient or medical staff through an alarm mechanism to prevent the change of ascites from being ignored.

[0033] In addition, the design of the elastic band 2 not only takes comfort into consideration, but also adapts to the patient's breathing movements to ensure the stability of the monitoring band during the patient's daily activities. The adaptability of the monitoring band body 42 and the precise monitoring of the monitoring component 41 combine to ensure immediate feedback of ascites changes. Compared with the existing method that relies on regular medical examinations, the present invention can monitor ascites in real time during the patient's daily life, detect abnormal abdominal distension in a timely manner, and provide an effective early warning mechanism, thereby improving the timeliness and effectiveness of treatment and reducing the risk of complications in patients.

[0034] In this embodiment, the monitor 4 includes a first shell 43 mounted on the base 1, and two monitoring components 41 are respectively mounted in the first shell 43. The first shell 43 is used to protect and support the monitoring components 41, and at the same time provide a stable installation platform. Ensure that the monitor 4 is not interfered with by the outside world during use. The material of the first shell 43 should have a certain durability and anti-interference ability, and can adapt to long-term wearing conditions.

[0035] In this embodiment, the monitor 4 includes a first housing 43 mounted on the base 1, and two monitoring components 41 are respectively mounted in the first housing 43. The first housing 43 provides support for the monitor 4, and the monitor 4 is fixed on the base 1 to ensure its stability and durability. Each monitoring component 41 includes a mounting sleeve 411, a plane scroll spring 412, a rotating shaft 413, a rotating member 414 and a photoelectric sensor 415, wherein the plane scroll spring 412 is connected to the rotating shaft 413, and the elastic torque of the plane scroll spring 412 plays a restoring role on the rotation of the rotating shaft 413, thereby ensuring the sensitivity and response speed of the monitoring system.

[0036] The mounting sleeve 411 is configured to accommodate and protect the planar volute spring 412 and the rotating shaft 413. The rotating shaft 413 is rotatably connected to the mounting sleeve 411 through a bearing, allowing the rotating shaft 413 to rotate freely without hindrance during the release process of the monitoring belt body 42. The rotating shaft 413 is connected to the planar volute spring 412, and when the monitoring belt body 42 is released, the rotating shaft 413 rotates accordingly, and the restoring force of the planar volute spring 412 provides the necessary rebound torque.

[0037] The rotating member 414 is connected to the rotating shaft 413 and rotates synchronously when the rotating shaft 413 rotates. The rotation of the rotating member 414 is monitored by the photoelectric sensor 415, and the photoelectric sensor 415 reflects the rotation of the rotating shaft 413 in real time by detecting the rotation angle or rotation speed of the rotating member 414. The rotation of the rotating member 414 is proportional to the release length of the monitoring belt body 42, and thus indirectly reflects the degree of expansion of the patient's abdomen.

[0038] One end of the monitoring belt body 42 is fixedly connected to the rotating shaft 413 and is wound around the rotating shaft 413, and the other end is connected to the elastic belt 2. When the patient's abdomen swells, the swelling of the abdomen drives the elastic belt 2 to expand outward, so that the monitoring belt body 42 is released from the rotating shaft 413. The degree of release of the monitoring belt body 42 is the degree of abdominal swelling. As the monitoring belt body 42 is released, the rotating shaft 413 rotates, thereby driving the rotating member 414 to rotate.

[0039] The first shell 43 is provided with a first notch 431 for the monitoring belt body 42 to extend out. The monitoring belt body 42 extends out through the first notch 431 to ensure that the monitoring belt body 42 can move smoothly and feedback changes in the abdomen.

[0040] The photoelectric sensor 415 is installed in the first housing 43 and is used to monitor the rotation of the rotating member 414 in real time. When the rotating member 414 rotates, the photoelectric sensor 415 detects the angle change of the rotating member 414 through the photoelectric principle. By monitoring the rotation degree of the rotating member 414, the release length of the monitoring belt body 42 can be determined, and the expansion degree of the patient's abdomen can be determined according to the release length of the monitoring belt body 42.

[0041] Furthermore, one end of the monitoring belt body 42 is fixed to the rotating shaft 413 and is wound around the rotating shaft 413. When the monitoring belt body 42 is released, the rotating shaft 413 will rotate as the monitoring belt body 42 extends. Therefore, the rotation of the rotating shaft 413 is directly related to the released length of the monitoring belt body 42. Specifically, when the length of the monitoring belt body 42 increases (that is, the released length increases), the rotating shaft 413 will rotate a certain angle accordingly. The rotating member 414 is connected to the rotating shaft 413, and the rotation of the rotating shaft 413 directly drives the rotation of the rotating member 414. The rotation angle or speed of the rotating member 414 reflects the degree of rotation of the rotating shaft 413. Therefore, the rotation degree of the rotating member 414 is proportional to the released length of the monitoring belt body 42. The longer the monitoring belt body 42 is, the greater the angle of rotation of the rotating shaft 413 is, and the rotation degree of the rotating member 414 will also increase accordingly. The photoelectric sensor 415 is installed in the first housing 43 and is responsible for real-time monitoring of the rotation angle of the rotating member 414. By detecting the rotation of the rotating member 414, the photoelectric sensor 415 can calculate the rotation angle of the shaft 413, and then deduce the release length of the monitoring belt body 42. Since the release length of the monitoring belt body 42 is directly related to the degree of abdominal distension of the patient, when the abdomen is distended, the stretching of the elastic band 2 will drive the monitoring belt body 42 to be released. The greater the degree of abdominal distension, the longer the release length of the monitoring belt body 42. Therefore, by measuring the release length of the monitoring belt body 42, the degree of abdominal distension of the patient can be indirectly deduced.

[0042] In summary, by monitoring the rotation degree of the rotating member 414, the release length of the monitoring belt body 42 can be determined, and then the degree of abdominal distension of the patient can be calculated. This method is based on the direct relationship between the rotation angle of the shaft and the release length of the monitoring belt body 42, and the relationship between the release length of the monitoring belt body 42 and the degree of abdominal distension. This principle enables the monitoring device to accurately reflect the patient's abdominal distension, thereby providing effective data support for the detection of ascites.

[0043] When the patient's abdomen is no longer swollen, or the abdomen returns to its previous state, the monitoring belt body 42 will be reeled due to the action of the plane scroll spring 412. The plane scroll spring 412 is an elastic element with restoring force, which is usually pre-stressed or pre-tensioned. One end of the plane scroll spring 412 is connected to the rotating shaft 413, and the other end is fixed to the mounting sleeve 411. When the monitoring belt body 42 is released and stretched, the plane scroll spring 412 provides a reverse torque through its elastic torque to push the rotating shaft 413 back to the initial position. The rotation of the rotating shaft 413 drives the rotation of the rotating member 414, and the photoelectric sensor 415 continuously monitors the rotation degree of the rotating member 414. As the monitoring belt body 42 is gradually retracted, the rotation angle of the rotating member 414 decreases, and the photoelectric sensor 415 detects the changes of the rotating member 414 in real time, thereby reflecting the reeling length of the monitoring belt body 42. By detecting the reeling degree of the monitoring belt body 42, it can be determined whether the abdomen has returned to a normal state.

[0044] During normal breathing, the patient's abdomen will expand and contract to a certain extent with inhalation and exhalation. At this time, the slight stretching and contraction of the elastic band 2 will drive the monitoring belt body 42 to stretch and rewind to a certain extent. The photoelectric sensor 415 will monitor the rotation of the rotating member 414, but due to the small expansion amplitude caused by breathing, the release length of the monitoring belt body 42 is usually very limited, and the rotation amplitude of the shaft 413 is also small. Although during normal breathing, the slight expansion of the patient's abdomen will cause the monitoring belt body 42 to be slightly released, the degree of expansion is usually not enough to reach the preset threshold. The preset threshold is to identify abnormal abdominal expansion, such as the accumulation of ascites, which usually far exceeds the amplitude of normal breathing.

[0045] In this embodiment, the photoelectric sensor 415 includes a light source transmitter 4151 and a light receiver 4152; a plurality of measuring rods 4141 are provided on the rotating member 414, and the plurality of measuring rods 4141 are arranged in a circularly equidistant array, the light source transmitter 4151 is provided between the measuring rods 4141, and the light receiver 4152 corresponds to the light source transmitter 4151, and is used to receive the light emitted by the light source transmitter 4151.

[0046] In this embodiment, the end of the elastic band 2 away from the base 1 is connected to a connecting band 5 adapted to the connecting assembly 3. The connecting assembly 3 includes a second housing 31, two gear shafts 32, a shift block 33, a locking member 34, a hinge shaft 35, a swing shaft 36 and a torsion spring 37. The detailed structure and working principle of each part are as follows: In this embodiment, the connecting assembly 3 includes a second housing 31, and two gear shafts 32 are rotatably mounted in the second housing 31. A mounting protrusion 311 is provided inside the second housing 31 to support the rotation of the hinge shaft 35. The hinge shaft 35 is rotatably connected to the mounting protrusion 311, and passes through the locking member 34 to be fixedly connected to the locking member 34. The locking member 34 is provided with a latch tooth that meshes with the gear shaft 32, and the latch tooth is used to control the rotation of the gear shaft 32 when the connecting belt 5 is inserted or removed.

[0047] The torsion spring 37 is sleeved on the hinge shaft 35, one end of the torsion spring 37 is connected to the mounting protrusion 311, and the other end is connected to the locking member 34, thereby providing a rotational force for the locking member 34, so that the locking member 34 is meshed and connected with the gear shaft 32. The function of the torsion spring 37 is to ensure that when the connecting belt 5 is inserted, the locking member 34 can rotate with the teeth on the gear shaft 32, and provide the necessary elastic force for the rotation of the gear shaft 32.

[0048] The swing shaft 36 is connected to the locking member 34, and the second housing 31 is provided with an arc-shaped notch 312 for the swing shaft 36 to swing. The hinge shaft 35 passes through the upper wall of the second housing 31 and is fixedly connected to the shift block 33. The swing shaft 36 passes through the arc-shaped notch 312 and is connected to the shift block 33. The function of the shift block 33 is to release the locking effect of the locking member 34 on the gear shaft 32 by shifting the shift block 33 when the connecting belt 5 needs to be pulled out.

[0049] The second housing 31 is provided with a second notch 313 for the connecting belt 5 to extend into and a third notch 314 for the connecting belt 5 to extend out. Two arc-shaped guide plates 315 are also provided in the second housing 31, and the arc-shaped guide plates 315 are used to guide the movement of the connecting belt 5. The connecting belt 5 is provided with teeth 51 that can mesh with the gear shaft 32, and is used to drive the gear shaft 32 to rotate.

[0050] The connecting belt 5 is a leather belt, which has flexibility and toughness, can adapt to the shape of the patient's abdomen and provide sufficient tension to ensure the stability of the monitoring belt.

[0051] In actual use, the connecting belt 5 is inserted from the second notch 313, and the teeth 51 on the connecting belt 5 mesh with the gear shaft 32, driving the gear shaft 32 to rotate. The locking member 34 is designed to be inclined. When the connecting belt 5 is inserted, the rotation of the gear shaft 32 will not be locked by the locking member 34. The locking member 34 moves along with the teeth on the gear shaft 32, and the torsion spring 37 is compressed. The connecting belt 5 continues to extend from the third notch 314 until the elastic belt 2 is attached to the patient's abdomen, at which time the insertion of the connecting belt 5 is stopped. The design of the connecting belt 5 and the connecting assembly 3 ensures that the monitoring belt is suitable for patients of different body shapes.

[0052] After the connection belt 5 is inserted, when the connection belt 5 needs to be pulled out, the gear shaft 32 meshes with the teeth 51 on the connection belt 5, and the gear shaft 32 needs to be rotated when pulling out. Since the locking teeth of the locking member 34 mesh with the gear shaft 32, and the locking member 34 is arranged at an angle, the locking member 34 will lock the reverse rotation of the gear shaft 32 and prevent it from rotating. Therefore, when pulling out the connection belt 5, it is necessary to move the shift block 33, and the shift block 33 will drive the swing shaft 36 to swing, thereby releasing the meshing of the locking member 34 and the gear shaft 32, allowing the gear shaft 32 to rotate, and completing the pulling out of the connection belt 5.

[0053] In this embodiment, the waist circumference monitoring belt for the prognosis assessment of patients with liver cirrhosis further comprises two shoulder strap components 6. The shoulder strap component 6 comprises two shoulder straps 61, a back strap 62 and a connecting piece 63. One end of the two shoulder straps 61 is respectively connected to the connecting piece 63, and the connecting piece 63 is connected to the connecting component 3. The other ends of the two shoulder straps 61 are connected to the back strap 62, and one end of the back strap 62 away from the shoulder strap 61 is connected to the base 1.

[0054] During use, the shoulder strap 61 is used to fix the monitoring belt in the appropriate position on the patient's abdomen to ensure the stability of the monitoring belt and prevent the monitoring belt from loosening or shifting due to abdominal expansion. The connecting piece 63 is connected to the connecting component 3, so that the shoulder strap component 6 can provide the required support force to keep the monitoring belt tightly fitted on the patient's abdomen. The back strap 62 is connected to the base 1 to further enhance the stability of the shoulder strap component 6 and ensure the firmness and reliability of the monitoring belt during the patient's activities.

[0055] In this embodiment, the waist circumference monitoring belt for the prognosis assessment of patients with liver cirrhosis further comprises a waist fixing belt 7. The waist fixing belt 7 is connected to the two elastic belts 2 via an elastic support sheet 71. A hook surface 72 is provided at one end of the waist fixing belt 7, and a velvet surface 73 is provided at the other end of the waist fixing belt 7, and a detachable connection is formed between the hook surface 72 and the velvet surface 73.

[0056] The elastic support sheet 71 is arc-shaped, and the elastic support sheet 71 is bent in the direction close to the patient's waist to provide support for the patient's waist. This design ensures that the waist fixing belt 7 can fit the patient's waist contour closely, provide stable support, and reduce the pressure of the abdominal circumference monitoring belt on the patient's waist, so that the patient can stay comfortable during daily activities. The arc-shaped structure of the elastic support sheet 71 enables it to provide uniform support in the patient's waist area, effectively reducing the discomfort that the abdominal circumference monitoring belt may cause when the abdomen is swollen.

[0057] Through the cooperation of the hook surface 72 and the velvet surface 73, the waist fixing belt 7 can be adjusted to ensure that it can provide a reliable and comfortable wearing experience for patients of different body shapes. When the patient needs to adjust the tightness of the waist fixing belt 7, he only needs to easily tear off the connection between the hook surface 72 and the velvet surface 73 to adjust it according to the patient's needs, so as to quickly adapt to the different changes in the patient's abdominal circumference.

[0058] In a second aspect of the present invention, a waist circumference monitoring system for prognosis assessment of patients with liver cirrhosis is provided.

[0059] The abdominal circumference monitoring system for the prognosis assessment of patients with liver cirrhosis comprises the above-mentioned abdominal circumference monitoring belt and a monitoring device 8 .

[0060] like Fig.10 As shown, in the second aspect of the present invention, a waist circumference monitoring system for evaluating the prognosis of patients with liver cirrhosis is provided. The waist circumference monitoring system for evaluating the prognosis of patients with liver cirrhosis comprises the above-mentioned waist circumference monitoring belt and a monitoring device 8.

[0061] The monitoring device 8 includes a data receiving module 81, an alarm 82 and a processor 83; the data receiving module 81 is used to receive the data monitored by the monitoring component 41 and determine the release length of the monitoring belt body 42; the processor 83 connects the alarm 82 and the data receiving module 81.

[0062] Furthermore, the data receiving module 81 is used to receive data monitored by the photoelectric sensor 415. The photoelectric sensor 415 monitors the rotation of the rotating member 414 in real time, and determines the release length of the monitoring belt body 42 by detecting the rotation degree of the rotating member 414, thereby reflecting the degree of abdominal distension of the patient. The data receiving module 81 converts the signal generated by the photoelectric sensor 415 into a digital signal and transmits it to the processor 83.

[0063] The processor 83 is used to analyze and process the received data, and determine the degree of expansion of the patient's abdomen according to the release length of the monitoring belt body 42. When the expansion degree exceeds a preset threshold, the processor 83 triggers the alarm 82 to send an alarm signal to the patient or medical staff, indicating that the patient or medical staff may have abnormal ascites and need further diagnosis and treatment.

[0064] The alarm 82 includes a sound alarm device, a light alarm device or a vibration alarm device, and different alarm modes can be selected as needed to ensure that the patient or medical staff can respond in time. When the release length of the monitoring belt body 42 exceeds a preset threshold, the alarm 82 sends a warning signal to remind the patient to take corresponding measures.

[0065] When the patient's abdominal distension reaches a threshold, indicating the possible presence of ascites, the system will automatically sound an alarm to remind doctors or caregivers to conduct further examinations on the patient. Further examinations include acute gastrointestinal bleeding and platelet counts, which are crucial for assessing the patient's overall condition and the severity of ascites.

[0066] Acute gastrointestinal bleeding is usually caused by esophageal varicose vein rupture or gastrointestinal ulcer bleeding caused by diseases such as liver cirrhosis. Whether a patient has acute gastrointestinal bleeding can usually be determined through clinical examinations (such as gastroscopy, colonoscopy) or symptoms (such as vomiting blood, black stools, etc.).

[0067] Platelet count is an indicator obtained through routine blood tests. A decrease in platelets may be related to factors such as liver dysfunction, hypersplenism, or acute gastrointestinal bleeding. Therefore, platelet count not only helps to assess the patient's coagulation function, but also provides support for the risk assessment of ascites.

[0068] Once these checks are completed, a "First Score" is calculated using the following formula.

[0069] The first score = 0.466 + 1.088 × acute upper gastrointestinal bleeding (1 = yes, 0 = no) + 1.147 × ascites (1 = yes, 0 = no) − 0.012 × platelet count.

[0070] Among them, acute upper gastrointestinal bleeding was represented by a binary variable (1=yes, 0=no), which was 1 if acute gastrointestinal bleeding existed and 0 otherwise.

[0071] Ascites was also represented by a binary variable (1 = yes, 0 = no), which was 1 if the patient was diagnosed with ascites and 0 otherwise.

[0072] The platelet count is a number obtained from a routine blood test and is measured in units of the number of platelets per microliter of blood.

[0073] After the first score is obtained, further examinations are performed, including the detection of total bilirubin, serum creatinine and serum albumin. These tests help to comprehensively evaluate the patient's liver function, kidney function and overall nutritional status, thereby providing more information support for subsequent treatment.

[0074] The detection of total bilirubin is used to evaluate the liver's bilirubin metabolism function, which is usually related to the degree of liver damage or the severity of liver failure. Elevated bilirubin levels may mean liver failure or liver cell damage.

[0075] Serum creatinine is a commonly used renal function indicator used to assess the patient's renal excretion capacity. The formation of ascites is closely related to renal function, and therefore the level of serum creatinine can reflect whether the patient's kidneys are damaged or have renal insufficiency.

[0076] Serum albumin is an important indicator reflecting the patient's nutritional status and liver synthetic function. A decrease in albumin levels usually indicates a weakened liver synthetic capacity or the occurrence of malnutrition.

[0077] The second score = 0.159 × the first score + 0.010 × total bilirubin (μmol / L) + 0.029 × age (years) + 0.011 × serum creatinine (μmol / L) − 0.037 × serum albumin (g / L).

[0078] A score value obtained by evaluating the clinical indicators of patients with cirrhosis is used to predict the patient's survival risk. The calculated second score will provide doctors with a comprehensive evaluation result to help determine the severity of the patient's ascites and the degree of liver and kidney damage. When the second score exceeds the set threshold, it indicates that the patient's condition is more serious and emergency intervention or intensive treatment measures are required.

[0079] For example, patients with a high second score may need further liver support, such as the use of diuretics to treat ascites or abdominal puncture to remove fluid to relieve abdominal pressure. At the same time, the second score can also help doctors assess whether the patient is suitable for liver transplantation or other higher-level treatment.

[0080] Through the comprehensive evaluation of the first score and the second score, the abdominal circumference monitoring system used for the prognosis evaluation of patients with cirrhosis can provide doctors with more accurate judgment basis, help to detect potential health problems early, avoid disease deterioration, and formulate personalized treatment plans, thereby significantly improving patients' treatment effects and quality of life.

[0081] In this embodiment, if Fig.11 and Fig.12 As shown, the system also includes a score calculation input module, wherein, as Fig.11As shown, the first score calculation interface is used to input clinical data related to the patient's acute upper gastrointestinal bleeding, ascites, and platelet count. The interface provides multiple input boxes and selection items, where users can enter or select the following data: Acute upper gastrointestinal bleeding (option: yes / no) Ascites (option: yes / no) Platelet count (unit: ×10^9 / L).

[0082] like Fig.12 As shown, the second score calculation interface is used to input data of total bilirubin, serum creatinine, serum albumin and patient age. The interface includes multiple input boxes, in which the user needs to enter the following: Total bilirubin (unit: μmol / L) Serum creatinine (unit: μmol / L) Serum albumin (unit: g / L) Patient age (unit: years).

[0083] In a third aspect of the present invention, a method for monitoring abdominal circumference for prognosis evaluation of patients with liver cirrhosis is provided, and the method comprises the following steps: The first step is to wear an abdominal circumference monitoring belt. The patient wears the two elastic bands 2 of the abdominal circumference monitoring belt used for prognosis assessment of patients with cirrhosis around the abdomen, ensuring that the elastic bands 2 are close to the abdominal surface and maintain appropriate tension to adapt to the patient's breathing movements and ensure that breathing is not hindered during wearing.

[0084] The second step is to connect the monitoring components. The distal end of the elastic band 2 is connected to the monitor 4 through the connecting component 3, and the monitor 4 is fixedly connected to the base 1. The monitor 4 includes two monitoring components 41, each of which is connected to a monitoring belt body 42. One end of the monitoring belt body 42 is connected to the elastic band 2, and the other end is wrapped around the monitoring component 41.

[0085] In the third step, the monitoring belt body is released. When the abdomen swells due to ascites accumulation, the patient's abdomen swells and causes the elastic belt 2 to stretch. The stretching of the elastic belt 2 causes the monitoring belt body 42 to be released together, and the monitoring component 41 begins to monitor the change in the length of the monitoring belt body 42.

[0086] The fourth step is to monitor the change of the release length. The monitoring component 41 continuously monitors the release length of the monitoring belt body 42 and determines the degree of abdominal distension according to the change of the release length. When the release length of the monitoring belt body 42 reaches or exceeds the preset threshold, it indicates that the degree of abdominal distension is abnormal, which may indicate excessive ascites.

[0087] The fifth step is to trigger the alarm. When the release length of the monitoring belt body 42 exceeds the set threshold, the monitor 4 triggers the alarm. The alarm can be issued to the patient or medical staff through sound, indicator light or other means, prompting the patient to undergo further examination to determine whether there is excessive ascites and to receive timely treatment.

[0088] The method also includes a prognostic risk assessment, which includes detecting whether the patient has acute gastrointestinal bleeding and platelet count, and calculating a first score; First score = 0.466 + 1.088 × acute upper gastrointestinal bleeding + 1.147 × ascites − 0.012 × platelet count; After obtaining the first score, the patient's total bilirubin, serum creatinine and serum albumin are further tested based on the first score. These tests are used to further evaluate the patient's liver function, kidney function and nutritional status, which are important for evaluating the patient's prognostic risk. The second score is calculated; The second score = 0.159 × the first score + 0.010 × total bilirubin (μmol / L) + 0.029 × age (years) + 0.011 × serum creatinine (μmol / L) − 0.037 × serum albumin (g / L); the second score is the prognostic risk assessment result.

[0089] By calculating the second score, the patient's prognostic risk assessment result is generated. This assessment result can be used as a reference for clinicians to make further treatment decisions. If the second score exceeds the preset clinical threshold, it means that the patient is at a higher risk and requires further medical intervention or close monitoring.

[0090] Cirrhosis is one of the major diseases that cause high mortality worldwide. Especially when it enters the decompensated stage or develops serious complications, the risk of death of patients increases significantly. Prognostic assessment of patients with cirrhosis is crucial for doctors to formulate treatment plans, reduce complications and improve the quality of life of patients. At present, the Child-Pugh score and MELD score commonly used in clinical practice have played a certain role in the risk prediction of cirrhosis, but their prediction range is limited, especially in the assessment of complications caused by portal hypertension (such as gastrointestinal bleeding and ascites). Therefore, a more accurate prognostic assessment method is needed to make up for this defect. The first score in this embodiment is proposed to solve this problem. Studies have shown that acute upper gastrointestinal bleeding and ascites are key risk factors for severe complications in the late stage of cirrhosis, while platelet count is closely related to portal hypertension and cirrhosis progression. Therefore, the first score can more accurately reflect the patient's bleeding risk and ascites accumulation risk by weighting acute upper gastrointestinal bleeding (1=yes, 0=no), ascites (1=yes, 0=no) and platelet count, and provides a risk assessment for specific complications of cirrhosis.

[0091] With the in-depth study of the long-term survival risk of patients with cirrhosis, the evaluation of acute events such as bleeding and ascites alone is no longer sufficient to fully predict the medium- and long-term prognosis of patients. The second score (i.e., the modified Liaoning score) adds indicators such as total bilirubin, serum creatinine, serum albumin, and patient age to the first score. These biochemical indicators cover aspects such as liver metabolism, renal excretion function, and nutritional status, and can more comprehensively reflect the patient's liver and kidney function status.

[0092] The second score in this embodiment shows higher prediction accuracy than the Child-Pugh score, MELD score and Liaoning score. For example, in the comparison of the area under the curve (AUC) in multiple validation cohorts, the second score has a significant advantage in predicting the 2-year survival rate, which indicates that it can more accurately predict the patient's survival risk. At the same time, the decision curve analysis also shows that the second score has a higher net benefit under different threshold probabilities. Further Nelson-Aalen cumulative risk curve analysis shows that when the second score is higher than 1.296, the patient's cumulative death rate is significantly increased, indicating its effectiveness in predicting long-term survival rate.

[0093] The combined evaluation of the first score and the second score can effectively predict the long-term survival risk of cirrhosis. This comprehensive evaluation method helps doctors to detect potential health problems in time before the patient's condition worsens, and then adopt personalized treatment plans to improve treatment effects and the patient's quality of life. This systematic monitoring based on multifactor analysis provides patients with cirrhosis with a more comprehensive prognostic management tool, makes up for the shortcomings of traditional scoring systems, and provides important support for precision medicine and personalized treatment.

[0094] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
