Description

Technical Field

[0001] The 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 hemostasis 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 a method of use. 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 fixedly connected to the two sides of the cylindrical tube respectively, the display is installed on the top of the cylindrical tube, the alarm is installed on the display, the elastic structure is arranged 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 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 part 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 flowing through the shell. At this time, pressure can continue to be applied to the swollen part, 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 part to avoid excessive tightening that may cause secondary injury to the patient's affected part, which is not conducive to the patient's recovery. Similarly, pressure on the affected part 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, an adhesive tape for arm binding is included. The radial artery compressor includes a pressing device and an emergency remedial device. The pressing device includes a fixed 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 fixed plate. The main pressing part is coupled with the main threaded tube through a main screw rod. 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 the auxiliary pressing assemblies to ensure that there is no bleeding and minimize the impact. The main pressing mechanism and all the auxiliary pressing assemblies can minimize the patient's discomfort.

[0006] 3) Chinese patent publication number CN113397641A discloses a new type of 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) China Patent Publication No. CN117045304A discloses a compression hemostasis device for cardiology nursing. In this technical application, it 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, and an arm placement slot is provided on the connecting beam. 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 drives the toothed sleeve to intermittently drive the first gear and the second gear to rotate through a motor, so that the hemostatic presser can move up and down to intermittently press the patient, which can replace medical staff to intermittently press and stop bleeding on the patient, reducing the burden on medical staff.

[0008] The above-mentioned prior art 1 involves multiple components such as pistons, elastic structures and airbags. Although the compression force can be adaptively adjusted, 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 be able to 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.

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

[0024] 1) Accurate 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 needs of the patient. 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 on the puncture site can be ensured to improve the hemostasis effect.

[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, and is particularly suitable for use in clinical emergencies.

[0030] 7) Enhanced hemostatic effect and adjustability: Through the combination of the sliding frame, compression piece A and compression piece B, precise hemostatic pressure can be applied to the puncture site, and multi-point and segmented compression can be achieved to ensure a wide and stable hemostatic effect; the use of the compression airbag further improves the hemostatic effect, and can be dynamically adjusted according to the different conditions of the patient, ensuring a continuous and stable treatment effect over a long period of time.

[0031] 8) Economy and cost-effectiveness: The design of this application reduces the cost of the equipment 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.

[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 a suitable length according to the patient's arm size, ensure that the wristband is firmly fixed, and fasten it tightly to the patient's wrist with Velcro or snap-on wristband;

[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 hemostasis force and operation time, and check the airbag compression force display;

[0061] Press to stop bleeding:

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

[0063] Mechanical pressing mode: using the mechanical pressing function of the device, the micro motor 402 in the pressing member 4 is enabled 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 hands of the nursing staff;

[0064] Monitor pressure: The pressure value in the compression airbag is monitored in real time through the parameter panel 101. 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 to 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 cooperate with the angle of 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 before use or when the compression is not in place during operation.

[0067] 4. Stop operation:

[0068] Release the compression: After the hemostasis is completed, the handle 206 is rotated counterclockwise and the compression airbag is released to release the compression on the puncture site to 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 using it immediately and obtain 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.
