Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a nursing device for patients with cirrhosis and ascites who need to prevent varicose veins. Background Technology

[0002] Ascites is a common clinical manifestation of liver decompensation. These patients often develop portal hypertension, leading to esophageal and gastric varices. The walls of these varices are thin and under high pressure; any factor that causes a sudden increase in intra-abdominal pressure (such as violent coughing, straining during bowel movements, or suddenly standing or bending over) can trigger rupture and bleeding, which is one of the most dangerous complications of cirrhosis with an extremely high mortality rate. Currently, clinical nursing care for patients with ascites due to cirrhosis mainly focuses on drug therapy (diuretics, portal pressure-lowering drugs), paracentesis, and health education (such as advising patients to avoid straining and maintain regular bowel movements).

[0003] Patent application number 202111423660.7 discloses a nursing device for patients with cirrhotic ascites who require varicose veins. Specifically, it relates to the field of cirrhotic ascites nursing technology, including a reference mounting frame with a cushion fixedly mounted on the upper right side. A folding mounting frame is hinged to the right end of the reference mounting frame. This invention, through the design of its dietary care components, can retain the nutritional components of food while controlling the patient's sodium intake, preventing hard and rough foods from causing further gastrointestinal bleeding and ascites. It is highly safe, improves the therapeutic effect of dietary care, and is beneficial to the recovery of the patient's ascites condition. It is highly practical. The rest adjustment component allows for adjustment of the backrest's tilt angle, making the patient's lying angle adjustable and providing high comfort. This is beneficial for the reduction of ascites, improving renal perfusion, eliminating water and sodium retention, and features a simple structure, high degree of automation, and prevention of varicose veins caused by portal hypertension. It is also highly applicable.

[0004] Although the device can adjust the body position, it cannot intelligently and in a coordinated manner prevent the increase of abdominal pressure; nurses also cannot continuously and quantitatively monitor the changes in the patient's abdominal circumference and intra-abdominal pressure, and can only rely on manual measurement and the patient's complaints, which is both lagging and subjective.

[0017] Please see Figure 1-5A nursing device for patients with cirrhosis and ascites who are trying to prevent varicose veins includes a bed body 1 and a nursing belt. A support frame 2 is fixedly installed on the bottom surface of the bed body 1. Casters are installed at the bottom support feet of the support frame 2. The bed body 1 can be moved and adjusted by the casters. A locking component is provided on the casters. When the bed body 1 is moved to a suitable position, the casters can be locked by the locking component to fix the position of the bed body 1. A headboard cushion 6 is fixedly installed on the rear side of the bed frame 1. The upper surface of the bed frame 1 is covered with a soft cushion 3 made of memory foam, which conforms to the curve of the human body. Telescopic armrest assemblies are provided on both the left and right sides of the bed frame 1. The telescopic armrest assembly includes a side frame 22 fixedly installed on the side of the bed frame 1. Multiple electric push rods 23 are fixedly installed on the side frame 22. A baffle 24 is fixedly installed at the top of the electric push rod 23. By activating the electric push rod, the baffle 24 is raised and lowered. When the patient turns over or gets up, the baffle 24 rises to provide support and prevents the patient from falling out of bed. When it is necessary to transfer the patient, the baffle 24 is lowered to avoid obstruction. The upper surface of the bed 1 is provided with three lifting components. One is located at the rear of the upper surface of the bed 1 to lift the upper body of the patient. Two are arranged side by side at the front of the upper surface of the bed 1 to lift the thighs of the patient. The middle upper surface of the cushion 3 is provided with a waist belt groove 4. The cushion 3 has three raised cushions 5. The position of the raised cushions 5 matches the lifting components. The lifting components include a lifting cavity 17 opened on the upper surface of the bed 1. A lifting plate 18 is hinged to the opening of the lifting cavity 17. The hinge axis between the lifting plate 18 and the inner wall of the lifting cavity 17 is facing the center of the bed 1. A hydraulic rod 19 is fixedly installed below the hinge axis. One end of the hydraulic rod 19 extends into the interior of the lifting cavity 17. A slider 20 is fixedly connected to one end of the hydraulic rod 19. A guide rod 21 is hinged to the upper surface of the slider 20. The guide rod 21 is hinged to the other end of the lifting plate 18.

[0018] A slide rod is fixedly installed inside the lifting cavity 17, and the guide rod 21 is slidably installed on the outer surface of the slide rod. A support block is fixedly installed on the other side of the lifting cavity 17 to support the other end of the lifting plate 18.

[0019] When it is necessary to lift the patient's upper body, the hydraulic rod 19 located at the rear pushes the slider 20 to move towards the foot of the bed, and lifts the rear end of the lifting plate 18 through the guide rod 21, causing it to rotate around the hinge axis, thereby slowly lifting the patient's back. Similarly, the two lifting components at the front move synchronously to lift the patient's thighs, flex the knee joint, and further relax the abdominal muscles. The whole process is smooth and coordinated.

[0020] The nursing waist belt includes a waist belt body 7. A control module 8 is fixedly installed at one end of the waist belt body 7. A touch screen 10 is fixedly installed on the upper surface of the control module 8 for displaying real-time data alarm information and allowing medical staff to set alarm thresholds and measurement modes. A wireless module 9 is fixedly installed on the side of the control module 8. A pressure sensor 16 is fixedly installed at the center of the bottom surface of the control module 8 for continuous monitoring of abdominal tension. Multiple miniature Doppler ultrasound sensors 15 are fixedly installed on the bottom surface of the control module 8 in an array for monitoring hemodynamic parameters of the liver area (such as hepatic vein blood flow spectrum and velocity) as a non-invasive indicator for assessing changes in portal vein pressure. A buckle 14 is fixedly connected to the other end of the waist belt body 7 and is installed on the side of the control module 8 through the buckle 14. An elastic stretch section 13 is provided in the middle of the waist belt body 7. The waist belt body 7 is made of hypoallergenic and breathable medical-grade elastic fabric. The elastic stretch section 13 ensures that the waist belt can adapt to changes in abdominal circumference and always fit comfortably. The waist belt body 7 is equipped with two airbags 11, each with a miniature air pump 12. The airbags 11 inflate the miniature air pumps 12, and the expansion of the miniature air pumps 12 can adjust the inner circle range of the waist belt body 7. By inflating or deflating the airbags 11, the miniature air pumps can not only fine-tune the tightness of the waist belt, but also perform regular and gentle periodic abdominal pressure, simulating the massage techniques of traditional Chinese medicine, promoting local blood circulation, and playing an auxiliary role in "promoting blood circulation and activating qi". At the same time, it reminds patients to avoid maintaining one posture for a long time. The control module 8 of the device is wirelessly connected to the hospital's central workstation or cloud via the wireless module 9. The detection data from the pressure sensor 16 and the Doppler ultrasound sensor 15 are transmitted to the control module 8 for analysis. Finally, all data is transmitted to the central workstation or cloud via the wireless module 9 to generate trend reports, which facilitates remote monitoring and the development of personalized care plans by medical staff.

[0021] Working principle: This nursing device for patients with cirrhosis and ascites who are trying to prevent varicose veins requires the patient to first wear a nursing belt and adjust the control module 8 on the belt to be directly above the patient's abdomen. The pressure sensor 16 and Doppler ultrasound sensor 15 on the bottom of the control module 8 are in contact with the patient's abdomen to continuously collect the patient's intra-abdominal pressure trend and blood flow data in the liver area. Then the patient lies on the bed 1 and the belt body 7 is placed in the belt groove 4 to avoid the patient feeling any sudden hard object.

[0022] The control module 8 is wirelessly connected to the hospital’s central workstation or cloud via the wireless module 9. The detection data from the pressure sensor 16 and the Doppler ultrasound sensor 15 are transmitted to the control module 8 for analysis. Finally, all data is transmitted to the central workstation or cloud via the wireless module 9 to generate trend reports, which facilitates remote monitoring and the development of personalized care plans by medical staff.

[0023] When the control module 8 detects a slight increase in abdominal circumference or when the patient has not turned over for a long time, the system can gently massage through the airbag 11 of the waist belt to remind the patient or nurse to assist in turning over slowly.

[0024] When a sudden increase in abdominal pressure caused by coughing or exertion is detected, or when vital signs become abnormal, the system immediately issues an audible and visual alarm (simultaneously on the touchscreen 10 and the nurse station), and can automatically adjust the bed to the optimal protective position with the upper body raised by 30° and the knees flexed by 15°, in order to minimize intra-abdominal pressure and pressure on the esophageal and gastric venous system.
