Description

Technical Field

[0001] The present invention relates to the field of cardiology nursing, in particular to a compression hemostasis device for cardiology nursing. Background Art

[0002] With the continuous development of medical technology, especially in the field of cardiology, more and more patients need to be treated through puncture surgery, such as radial artery puncture. Radial artery puncture is a common operation in cardiology and is often used for coronary angiography, interventional treatment, etc. However, hemostasis needs to be performed quickly and effectively after radial artery puncture to avoid bleeding and ensure patient safety. At present, traditional hemostasis methods mainly rely on manual compression or tourniquets. This method has many limitations, such as the hemostatic effect is difficult to accurately control, the operation process is prone to discomfort, and long-term pressure may cause ischemia of the tissues around the puncture site, affecting the patient's comfort and recovery speed.

[0003] To solve this problem, in recent years, some mechanized or intelligent hemostasis devices have been gradually developed. These devices can apply uniform pressure through automated control, reduce the operating burden of nursing staff, and effectively avoid excessive compression.

[0004] 1) Chinese patent publication number CN116570336B discloses a pressure-controlled femoral artery compressor and its use method. In this technical application, it includes a femoral artery compression component, which includes two fixed structures, a display, an alarm, an elastic structure, a pressure sensor, an airbag, a detachable hemostatic structure, a cylindrical tube and a switch installed on the upper wall of the cylindrical tube. The two elastic structures are respectively fixedly connected to the two sides of the cylindrical tube, the display is installed on the top of the cylindrical tube, the alarm is installed on the display, the elastic structure is provided on the cylindrical tube, the pressure sensor is installed on the bottom of the elastic structure, the pressure sensor is fixedly connected to the airbag, the bottom of the airbag is fixedly connected to the detachable hemostatic structure, and an auxiliary adjustment component. The distance between the airbag and the fourth piston can be adjusted by adjusting the structure, so that the amount of air filled in the sealing tube can be adjusted, so that when pressure is applied to the airbag, the elastic sealing structure is pushed to move by appropriate air pressure to keep the two connecting tubes closed, so that the gas inside the cylindrical tube is constant, the pressure is kept fixed, and loosening is avoided. When the affected area swells, the airbag continues to supply air and pushes the third piston and the connecting tube to be staggered by air pressure, so that the upper and lower chambers of the cylindrical tube are kept in circulation through the shell. At this time, pressure can be continued to be applied to the swollen area, and the elastic structure can be moved upward. In this way, the pressure can be adaptively adjusted according to the situation of the patient's affected area to avoid excessive tightening and secondary injury to the patient's affected area, which is not conducive to the patient's recovery. Similarly, pressure on the affected area can be maintained.

[0005] 2) Chinese patent publication number CN111449710B discloses a multi-point pressing radial artery compressor for cardiovascular intervention surgery. In this technical application, it includes an adhesive tape for arm binding. The radial artery compressor includes a pressing device and an emergency remedial device. The pressing device includes a fixing plate, a main pressing mechanism and two auxiliary pressing mechanisms. The auxiliary pressing mechanism includes a cylindrical panel and an auxiliary pressing assembly. The main pressing mechanism includes a main threaded tube and a main pressing part vertically mounted on the fixing plate. The main pressing part is transmitted through the main screw and the main threaded tube. The emergency remedial device includes two emergency mechanisms and a push-pull assembly. The present invention can perform multi-point pressing on the puncture site and its sides through the main pressing mechanism and all auxiliary pressing assemblies to ensure that there is no bleeding and minimize the impact. The main pressing mechanism and all auxiliary pressing assemblies can minimize the patient's discomfort.

[0006] 3) Chinese patent publication number CN113397641A discloses a new femoral artery compressor. In this technical application, it is mainly composed of: a compression plate, a pressure block, a strap and a pressure mechanism. The pressure block is arranged on the bottom surface of the compression plate, the strap is arranged on the left and right ends of the compression plate, and the pressure mechanism is arranged on the top surface of the compression plate and is detachably connected to the compression plate. The new femoral artery compressor of the present invention has a simple structure and strong practicality. When the patient's bleeding volume is small, direct binding can achieve a good hemostasis effect. When the bleeding volume is large, the pressure mechanism can be installed at any time and the top pressure screw can be extended by a motor to control the size of the compression force. Compared with manual compression, the effect is better, the compression force is more stable and lasting, and the real-time compression force can be detected according to the pressure sensor. When the bleeding volume slows down, the compression force can be reduced in time to improve the patient's comfort.

[0007] 4) Chinese Patent Publication No. CN117045304A discloses a compression hemostasis device for cardiology nursing. This patent application includes a base, a connecting beam, a placement box, a connecting ring, an adjustment mechanism, and a pressing mechanism. The top of the base is connected to a connecting beam, which is provided with an arm placement slot. The top of the connecting beam is connected to a placement box, and the bottom of the placement box is connected to a connecting ring. The placement box is provided with an adjustment mechanism and a pressing mechanism. The present invention uses a motor to drive a toothed sleeve to intermittently rotate the first and second gears, allowing the hemostatic press to move up and down to intermittently apply pressure to the patient. This can replace medical staff in performing intermittent compression to stop bleeding, reducing the burden on medical staff.

[0008] The above-mentioned prior art 1 involves multiple components such as pistons, elastic structures and airbags. Although it can adaptively adjust the compression force, the overall structure is relatively complex and requires medical staff to have high operating skills and experience; and although prior art 2 can perform multi-point pressing, it requires medical staff to adjust and operate through multiple mechanisms, and it cannot adapt to individual differences and changes in patients; and although prior art 3 can be adjusted according to changes in bleeding volume, the overall compression method may not guarantee the comfort of patients during long-term use, especially under higher compression force, the patient may feel uncomfortable; and in prior art 4, since the designed pressing mechanism is a fixed intermittent pressing mode, it may not be possible to flexibly adjust the compression force and compression position according to the specific situation of the patient, and it also has the problem of uneven compression force.

[0022] The present invention application has great improvements in accurately adjusting the compression force, improving patient comfort, ensuring stable treatment effects, and convenient operation. Through innovative design, this application can not only provide efficient and stable hemostatic effects, but also improve the work efficiency of medical staff and provide patients with a safer and more comfortable treatment experience.

[0023] The technical effects of the present invention are mainly reflected in the following aspects:

[0024] 1) Precise pressure adjustment: The hemostasis module configured in this application can achieve precise pressure adjustment. Through the cooperation of the handle and the compression unit, the hemostasis site and pressure can be fine-tuned according to the patient's needs. Through the engagement of the main gear and the arc-shaped rack, a large range of compression area can be achieved, and uniform and stable compression can be ensured on the puncture site, thereby improving the hemostasis effect.

[0025] 2) Improve patient comfort: The flexible compression design of this application uses a compression airbag to perform compression, avoiding the direct compression of the patient's skin by traditional compression methods, significantly improving the patient's comfort. By repeatedly pressing the inflated airbag, the air pressure in the airbag can be adjusted to ensure continuous and uniform compression force, avoiding excessive compression causing discomfort or secondary injury to the patient.

[0026] 3) Intelligent monitoring and real-time feedback: The device of this application is equipped with a pressure sensing unit, and the pressure changes of the airbag are monitored in real time through a pressure patch. The pressure patch feeds back the pressure information to the parameter panel, allowing the nursing staff to view the compression force parameters in real time to ensure that excessive pressure is not applied to the patient's puncture site during the hemostasis process, thereby reducing unnecessary injuries.

Medical staff can quickly put it on and make necessary adjustments, saving operation time and improving work efficiency.

[0028] 5) Multi-function operation mode: This application provides two operation modes: manual compression and mechanical compression. When the device has no power support, it can provide hemostasis function through manual compression; when there is sufficient power, the mechanical compression mode can free the hands of medical staff, improve work efficiency and reduce manual fatigue.

[0029] 6) Structural optimization and ease of use: The wristband design makes this hemostatic device suitable for most patients and can be adjusted according to the size of the patient's wrist. It uses a Velcro wristband or a snap-on wristband, which is easy to wear and adjust quickly, making it particularly suitable for use in clinical emergencies.

[0030] 7) Enhanced hemostatic effect and adjustability: The combination of the sliding frame, compression member A, and compression member B allows precise hemostatic pressure to be applied to the puncture site, achieving multi-point, segmented compression to ensure extensive and stable hemostatic effects. The use of compression airbags further enhances the hemostatic effect and can be dynamically adjusted according to the patient's individual conditions, ensuring a sustained and stable treatment effect over a long period of time.

[0031] 8) Economy and cost-effectiveness: The design of this application reduces equipment costs while ensuring efficient hemostasis. By reducing the need for high-cost components, it can maximize the treatment effect while reducing the patient's treatment cost burden. Compared with other complex designs, the economy of this application makes it more suitable for application in a wide range of medical institutions and patient groups.

[0055] 1. Preparation:

[0056] Check the device: ensure that the wristband module 1 and the hemostasis module 2 are in good condition, the parameter panel 101 displays normally, and the inflatable balloon 3 is intact;

[0057] Wearing the wristband: Adjust the wristband module 1 to the appropriate length according to the patient's arm size, ensure that the wristband is firmly fixed, and fasten it tightly to the patient's wrist using Velcro or snap-on wristbands;

[0058] Connect the hemostasis module 2: Connect the upper bracket 201 of the hemostasis module 2 to the wristband module 1, ensuring that all connecting parts are tightened and the device is in working condition.

[0059] 2. Hemostasis operation:

[0060] Adjust the compression force: open the parameter panel 101 on the device, set the appropriate hemostatic force and operation time, and check the airbag compression force display;

[0061] Press to stop bleeding:

[0062] Manual compression mode: Use the handle 206 to manually adjust the compression intensity. The front end of the handle 206 will cooperate with the compression groove 209 of the stop block 204. By rotating the handle 206, the main gear 208 is driven to rotate the compression members A210 and B, so that the compression plates 213 on both sides can accurately compress the puncture site.

[0063] Mechanical compression mode: Using the mechanical compression function of the device, the micro motor 402 in the pressing member 4 is activated to drive the gear 403, automatically pressing the inflated balloon 3 to supply air, thereby enhancing (assisting) the compression effect. This mode is suitable for situations where continuous manual operation is not required, freeing the caregiver's hands;

[0064] Monitor pressure: The parameter panel 101 monitors the pressure value in the compression airbag in real time. The pressure patch automatically senses the pressure of the airbag on the skin and feeds back to the parameter panel 101 through an electrical connection, helping the caregiver ensure that the pressure applied is appropriate.

[0065] 3. Compression adjustment:

[0066] Fine-tune the hemostasis position: According to the patient's specific situation, adjust the handle 206 to match the angle of the compression members A210 and B to achieve a more precise compression position. The stop block 204 can be fine-tuned through the handle 206 to ensure maximum hemostasis effect. The compression adjustment can be made in the early stage of use or when the compression is not in place during operation.

[0067] 4. Stop operation:

[0068] Release the compression: After hemostasis is completed, the handle 206 is rotated counterclockwise to release the compression airbag to release the compression on the puncture site and ensure that the patient's blood flow returns to normal;

[0069] Disassembly: Gently release the wristband from the hemostasis module 2, ensuring patient comfort and without unnecessary friction or pressure.

[0070] 5. Notes:

[0071] Pressure time control: Avoid applying excessive pressure for a long time to avoid discomfort or local ischemia. Check the pressure regularly and adjust it as needed;

[0072] Observe the patient's reaction: During use, observe the patient's reaction at any time. If skin discoloration, limb numbness or other abnormalities are found, stop use immediately and seek appropriate medical treatment;

[0073] Check the status of the device: Before each use, check whether the airbag is inflated normally, whether the battery or power supply is sufficient, and ensure that the device is fault-free.

[0074] 6. Maintenance:

[0075] Cleaning: After each use, wipe the surface of the device to keep it clean to avoid dust accumulation that may affect the normal operation of sensors and electronic components;

[0076] Inspection: Regularly check the wear of the wristband, hemostasis module 2, airbag and other components to ensure that each component is in good working condition.
