Description

Technical Field

[0001] This invention belongs to the technical field of medical hemostasis devices, specifically, it relates to a hemostasis auxiliary compression device for use in nursing cardiology. Background Technology

[0002] In the field of cardiology nursing, effective compression of the puncture site is necessary after radial artery puncture (such as coronary angiography, stent implantation, etc.) to achieve hemostasis. This is a key step in preventing complications such as bleeding and hematoma.

[0003] Currently, commonly used hemostasis methods in clinical practice include manual compression and compression using traditional hemostatic devices.

[0004] Manual compression relies on the experience of medical staff to control the pressure, which is not only labor-intensive but also has poor pressure stability. Insufficient pressure can easily lead to bleeding, while excessive pressure can cause local tissue ischemia.

[0005] Traditional hemostatic devices mostly adopt an overall compression structure, which can reduce manpower consumption, but the continuous compression of the muscles around the puncture point can easily cause patients to experience discomfort such as soreness and numbness. Especially during long-term compression (4-6 hours), patients have poor tolerance. Both have certain shortcomings. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a medical hemostatic device that can overcome or at least partially solve the above problems.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a hemostatic auxiliary compression device for use in nursing cardiology, including a fixed base, and further comprising:

[0008] Adjustment components are mounted on the fixed base;

[0009] The compression component, installed at the bottom of the fixed base, can compress the patient's radial artery by adjusting the component, thereby achieving hemostasis;

[0010] The compression assembly includes a device housing, a compression plate, and compression airbags. The device housing has a bottom opening and is installed at the bottom of the fixed base. The compression plate is slidably connected inside the device housing. Multiple sets of compression airbags are installed at the bottom of the compression plate. The compression airbags are strip-shaped and perpendicular to the direction of the radial artery.

[0011] By compressing the radial artery with an airbag, blood flow through the radial artery can be prevented. At the same time, by adjusting the air pressure in the airbags away from the puncture point and keeping the air pressure in the airbags closer to the radial artery constant, the pressure on the patient is reduced. The air pressure in each airbag is reduced one by one, and after recovery, it can have a peristaltic effect, massaging and relaxing the muscles that were previously compressed.

[0012] Furthermore, the adjustment assembly includes a piston rod, a piston plate, an adjustment knob, and a push rod. The piston rod is fixedly connected to a fixed base, the piston plate is slidably connected inside the piston rod, the adjustment knob is threadedly connected to the piston rod, and the push rod is fixedly connected to the adjustment knob. One end of the push rod is rotatably connected to the piston plate.

[0013] Furthermore, the fixed base is provided with a connection hole, and the two ends of the connection hole are respectively connected to the piston column and the equipment housing.

[0014] Furthermore, the compression plate is provided with a device cavity, and an air pump is fixedly connected in the device cavity. A connecting pipe is connected to the air outlet of the air pump. The connecting pipe has multiple groups of branch pipes. The air outlets of the branch pipes are respectively connected to multiple groups of compression airbags, and electronic valves are connected in the branch pipes.

[0015] Furthermore, the bottom of the compression airbag is provided with multiple sets of exhaust ports, each of which is equipped with an electronic valve. The exhaust ports are angled to discharge gas onto the skin of the radial artery.

[0016] Furthermore, a spring is fixedly connected to the pressure plate, and the other end of the spring is connected to the equipment housing.

[0017] Furthermore, the device housing is detachably connected to the bottom of the fixed base.

[0018] Furthermore, the device housing is provided with a sealing ring at the connection hole.

[0019] Furthermore, strap one and strap two are installed on the fixed base.

[0020] Furthermore, the first strap is equipped with Velcro 1, and the second strap is equipped with Velcro 2.

[0021] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: while achieving hemostasis after radial artery puncture, the present invention relieves local muscle tension and discomfort of patients through the dynamic adjustment mode of the airbag, which not only ensures the stability of the hemostasis effect, but also significantly improves the comfort of patients.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] Example: Refer to Figure 1-7A hemostatic auxiliary compression device for cardiology nursing includes a fixed base 1 and an adjustment component mounted on the fixed base 1. The compression component is mounted at the bottom of the fixed base 1. The adjustment component allows the compression component to compress the patient's radial artery, thereby achieving hemostasis. The compression component includes a housing 4, a compression plate 5, and compression airbags 6. The housing 4 has a bottom opening and is mounted at the bottom of the fixed base 1. The compression plate 5 is slidably connected within the housing 4. Multiple compression airbags 6 are mounted at the bottom of the compression plate 5. The compression airbags 6 are strip-shaped and perpendicular to the direction of the radial artery. By compressing the radial artery with the compression airbags 6, blood flow through the radial artery is prevented. Simultaneously, by adjusting the air pressure within the compression airbags 6 away from the puncture point while maintaining a constant air pressure within the compression airbags 6 near the radial artery, pressure on the patient is reduced. The pressure within each compression airbag 6 is gradually reduced, and upon recovery, a peristaltic effect is achieved, massaging and relaxing the previously compressed muscles.

[0033] The adjustment assembly includes a piston rod 2, a piston plate 201, an adjustment knob 3, and a push rod 301. The piston rod 2 is fixedly connected to the fixed base 1, the piston plate 201 is slidably connected inside the piston rod 2, the adjustment knob 3 is threadedly connected to the piston rod 2, and the push rod 301 is fixedly connected to the adjustment knob 3. One end of the push rod 301 is rotatably connected to the piston plate 201.

[0034] The piston column 2 is made of high-strength medical-grade polycarbonate material, which has excellent pressure resistance and corrosion resistance. Its inner wall is precision polished to ensure smooth sliding and sealing of the piston plate 201. A medical-grade silicone sealing ring is wrapped around the edge of the piston plate 201, further enhancing the airtightness of the piston column 2 and preventing air leakage from affecting the compression effect. The outer surface of the adjustment knob 3 not only has an anti-slip texture but also is marked with pressure scales. Each rotation corresponds to a 0.5 kg pressure change, allowing medical personnel to accurately control the compression intensity. The push rod 301 is made of medical-grade stainless steel, which has high strength and stability. A miniature bearing is installed at its rotating connection with the piston plate 201, reducing friction during relative rotation and making the adjustment process more effortless and smooth.

[0035] A connection hole 105 is provided on the fixed base 1, and the two ends of the connection hole 105 are respectively connected to the piston column 2 and the equipment housing 4.

[0036] The compression plate 5 has an equipment cavity, and an air pump 501 is fixedly connected inside the equipment cavity. A connecting pipe 502 is connected to the air outlet of the air pump 501. The connecting pipe 502 has multiple sets of branch pipes, and the air outlets of the branch pipes are respectively connected to multiple sets of compression airbags 6. An electronic valve is connected inside the branch pipe.

[0037] The bottom of the compression airbag 6 is provided with multiple sets of exhaust ports 601. An electronic valve is installed inside the exhaust port 601. The exhaust port 601 is tilted to discharge gas to the skin on the surface of the radial artery.

[0038] The compression airbag 6 is made of highly elastic medical-grade silicone material with a thickness of 0.3-0.5mm. It possesses excellent elasticity and resilience, allowing it to closely conform to the patient's skin and ensure effective compression. The surface of the airbag has a frosted finish, increasing friction with the skin and preventing displacement during compression. The exhaust port 601 has a diameter of 0.5-1mm and an inclination angle of 30-45 degrees. This design ensures smooth gas expulsion and even distribution of the expelled gas across the skin surface. The electronic valve inside the exhaust port 601 is also a miniature solenoid valve with the same performance parameters as the electronic valve on the branch pipe, enabling precise control of the exhaust volume and speed.

[0039] A spring component 402 is fixedly connected to the pressure plate 5, and the other end of the spring component 402 is connected to the equipment housing 4.

[0040] The device housing 4 is detachably connected to the bottom of the fixed base 1.

[0041] The housing 4 is provided with a sealing ring 401 at the connection hole 105.

[0042] The fixation base 1 is equipped with strap 101 and strap 2 103. Fixation base 1 is made of medical-grade silicone material, which is soft and elastic, allowing it to closely conform to the patient's wrist and forearm skin, improving patient comfort. The surface of fixation base 1 has undergone antibacterial treatment, effectively inhibiting bacterial growth and reproduction, and reducing the risk of skin infection. Straps 101 and 2 103 are both made of elastic medical webbing, with a width of 2-3 cm and an adjustable length up to 30 cm to accommodate patients of different body types.

[0043] The first strap 101 is equipped with hook and loop fastener 102, and the second strap 103 is equipped with hook and loop fastener 104. Both hook and loop fastener 102 and hook and loop fastener 104 are medical-grade nylon hook and loop fasteners, which have strong adhesion and a long service life, maintaining good adhesion even after more than 5,000 times of application and separation. The surface of the hook and loop fasteners has been rounded to avoid scratches to the patient's skin caused by sharp edges.

[0044] Before the radial artery puncture, the medical staff will attach the fixing base 1 to the skin of the patient's forearm and wrist, align the device shell 4 with the puncture point area, wrap the wrist with strap 101 and strap 203, and fix it with Velcro 102 and Velcro 204. The tightness will be adjusted until the patient does not feel obvious pressure and the device does not slip. At the same time, it will be confirmed again that the patient has no discomfort feedback.

[0045] Check all components: confirm that the adjustment knob 3 is in its initial state (e.g., when turned counterclockwise to the top, the piston plate 201 moves upward and the space inside the piston column 2 is at its maximum), the air pump 501, electronic valve, and exhaust port 601 electronic valve are in the closed state, the compression airbag 6 has no air pressure, and ensure that all functions of the device are normal.

[0046] After the radial artery puncture is completed, the medical staff immediately rotate the adjustment knob 3 clockwise, and the top rod 301 presses down the piston plate 201. The air pressure in the piston column 2 is transmitted to the device housing 4 through the connection hole 105. The change in air pressure pushes the compression plate 5 down, and the compression airbag 6 contacts the skin of the patient's radial artery puncture point.

[0047] Continuously rotate the adjustment knob 3 to apply sufficient pressure to the puncture point with the compression balloon 6 according to the patient's blood pressure, puncture situation, etc. (judged by clinical experience or pressure feedback to ensure that blood flow is blocked). At this time, the compression balloon 6 near the puncture point is synchronously compressed due to air pressure transmission, maintaining constant pressure on the puncture point.

[0048] At this time, the airbag 6 is in a constant pressure state, that is, it contains a certain amount of gas inside and maintains it stably, without taking in or venting air.

[0049] In the initial postoperative period, medical staff will check on the patient every 15-30 minutes to observe the puncture site and maintain a constant air pressure in the compression cuff 6 near the puncture site (this can be adjusted slightly by adjusting knob 3 or supplemented by air pump 501; a pressure sensor can be added inside the compression cuff 6). For the compression cuff 6 far from the puncture site, the air pressure will be adjusted by air pump 501 and the branch-tube electronic valve to achieve the following two relaxation modes:

[0050] Intestinal peristalsis-like mode: Controlled by a preset program, starting from the side away from the puncture point, the first set of airbags deflates and depressurizes first, and the next set of adjacent airbags deflates synchronously or slightly later, forming a wave-like pressure decrease; then in the reverse order, they are inflated and reset in sequence, so that the pressure is transmitted in a periodic wave along the direction away from the puncture point, simulating the physiological rhythm of intestinal peristalsis, and relieving muscle tension through continuous and regular pressure changes.

[0051] Irregular independent adjustment mode: Medical staff can operate any group of airbags far away from the puncture point independently based on patient feedback, or the patient can operate them independently through the control module (which can be set on the device shell 4 or on the fixed base 1, with a control panel and corresponding control system set up, and a power supply battery is required). They can randomly select to inflate or deflate the airbags to form irregular pressure fluctuations. This breaks the continuous tension of the muscles through non-periodic stimulation, resulting in an alternative relaxation effect.

[0052] The two modes can be switched according to the patient's tolerance and comfort needs. During this time, if the patient complains of local discomfort, medical staff can promptly adjust the body pressure by adjusting knob 3 (slight rotation, such as 1 / 4 turn), or operate the corresponding compression airbag 6 electronic valve to deflate / inflate, and record the adjustment.

[0053] Four to six hours after the operation (based on clinical assessment that hemostasis has been achieved), medical staff begin to gradually reduce pressure.

[0054] For the compression airbag 6 near the puncture point, if the adjustment component is used for pressurization, rotate the adjustment knob 3 counterclockwise, lift the piston plate 201 with the top rod 301, reduce the air pressure inside the piston column 2, and the compression plate 5 moves upward under the elastic force of the spring 402, thus reducing the pressure of the compression airbag 6 on the puncture point; if the air pump 501 is used for pressurization, open the corresponding branch electronic valve to slowly release air and reduce pressure. Observe for 10-15 minutes after each decompression, and perform the next decompression only after confirming that there is no bleeding.

[0055] For the compression balloon 6 located far from the puncture point, the air pressure is gradually reduced by pumping air out through the air pump 501 or venting air out through the electronic valve at the exhaust port 601, while simultaneously observing whether there is any bleeding at the puncture point.

[0056] Complete decompression: Once hemostasis at the puncture site is confirmed to be good (e.g., no bleeding after 5-10 minutes of observation), medical staff remove bandage 101 and bandage 203, remove the device, gently wipe any remaining adhesive residue on the patient's skin with a medical alcohol swab, and inform the patient of precautions for puncture site care, such as keeping it clean and dry and avoiding strenuous activity.

[0057] Component cleaning and storage: Medical staff disassemble detachable components. This application is connected by bolts. By removing the bolts, the components are disassembled and cleaned in accordance with the medical device disinfection specifications (wipe or soak with medical wipes for disinfection, and avoid liquid entering electronic components). After drying, they are stored. When ready for use, check whether the electronic valve, air pump 501, etc. are functioning properly to ensure safe use next time.

[0058] If bleeding occurs at the puncture site, medical staff should immediately rotate the adjustment knob 3 clockwise to increase pressure, or start the air pump 501 to inflate the compression bag 6 near the puncture site to increase pressure and observe whether the bleeding stops. If this is ineffective, check if the device has shifted, reposition and fix it before adjusting the pressure, and promptly report to the doctor to take further measures as prescribed.

[0059] If the patient's discomfort worsens (such as severe local pain or cyanosis of the skin), medical staff should immediately rotate the adjustment knob 3 counterclockwise to reduce pressure, open the corresponding compression airbag 6 electronic valve to quickly release air, remove the device to check the skin, and if necessary, change the compression position or device, report to the doctor for further treatment, and closely monitor changes in the patient's vital signs.

[0060] This invention achieves hemostasis after radial artery puncture while relieving local muscle tension and discomfort in patients through a dynamic adjustment mode of the airbag, thus ensuring the stability of the hemostatic effect and significantly improving patient comfort.
