Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable pressure hemostasis device and its adjustment method. Background Technology

[0002] Adjustable pressure hemostasis devices typically consist of a fixing device, an adjusting handle, a pressure regulator, a hemostatic pad, and a protective device.

[0003] Chinese patent CN211609934U discloses a non-invasive hemostatic clamp device with adjustable pressure, comprising an inner sleeve, an outer sleeve, an adjustment knob, a base, a positioning block, a central shaft, and a pressure spring. A lower clamp is mounted on one side of the inner sleeve, and an upper clamp is mounted on one side of the outer sleeve. The outer side of the central shaft formed by the cylindrical inner sleeve and the lower clamp, and the inner side of the central shaft formed by the cylindrical outer sleeve and the upper clamp, form a cylindrical sleeve structure. Within the cylindrical sleeve structure, the positioning block, the central shaft, and the pressure spring form an axis, which is then joined together by a tenon-and-mortise joint. The inner and outer sleeves are coaxially connected and interlocked through the base and adjustment knob. This patent features a simple structure, adjustable and stable clamping pressure, suitable size, good hemostatic effect, and is non-invasive and harmless to blood vessels. It facilitates vascular suturing by medical personnel, avoids complications such as endothelial edema, spasm, and even thrombosis, and significantly reduces the workload of medical staff.

[0004] In the aforementioned patent, the inner and outer sleeves are coaxially connected and interlocked by the base and adjustment knob, making the patent structure simple, with adjustable and stable clamping pressure, appropriate size, good hemostasis effect, and no invasiveness to blood vessels, reducing the workload of medical staff. However, the lack of a pressure regulating device means that different individuals may have different physiological conditions and signs, requiring adjustment of the pressure of the hemostasis device according to the specific situation. The lack of a pressure regulating device may lead to the inability to meet the individualized needs of different patients, increasing the uncertainty of treatment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable pressure hemostasis device and adjustment method, solving the problems mentioned in the background section.

At the top, the limiting ring is fixedly installed on the top of the extension plate, and a limiting groove is formed on the surface of the limiting ring. An extension hole is formed on the surface of the extension plate. The threaded rotating rod is rotatably installed on the inner wall of the extension hole. The rotating plate is fixedly installed on the top of the threaded rotating rod. The hollow cylinder is fixedly installed on the bottom of the rotating plate. The sliding rod is slidably installed on the inner wall of the hollow cylinder. The slider is slidably installed on the bottom of the adjusting plate. The pressurized airbag is fixedly installed on the surface of the slider. A return spring is provided between the slider and the adjusting plate. Slow adjustment allows medical staff to make individualized pressure adjustments according to the specific condition of the patient. Different patients may have different physiological conditions and wound conditions. Therefore, slow adjustment can more accurately adapt to different treatment needs.

[0007] According to the above technical solution, a first spring is provided between the slide rod and the hollow cylinder, the rotating plate is in contact with the limiting groove, and an adjustment hole is opened on the surface of the adjusting plate. The slide rod can be driven to reset by the first spring.

[0008] According to the above technical solution, the threaded rotating rod contacts the pressurized airbag through the adjustment hole, the inner wall of the extended hole is provided with a rotating groove, and a second spring is provided between the rubber plate and the adjustment plate, which can drive the rubber plate to reset.

[0009] According to the above technical solution, it also includes a disassembly device and a limiting device. The disassembly device includes a placement rod, a moving plate, a hollow plate, a limiting rod, a polygonal plate, and an arc-shaped spring. The threaded rotating rod moves upward to disengage from the pressurized airbag. The placement rod is fixedly installed on the top of the adjusting plate. The moving plate is slidably installed on the surface of the placement rod. The hollow plate is fixedly installed on the surface of the vertical sliding plate. The limiting rod slides through the surface of the vertical sliding plate. An arc-shaped spring is provided between the moving plate and the adjusting plate. The polygonal plate is fixedly installed on the surface of the limiting rod. A protective rod is slidably installed on the surface of the vertical sliding plate. In some emergency situations, rapid medical intervention is required. The ability to quickly disassemble the hemostatic device allows medical personnel to treat patients more quickly, reducing waiting time and improving treatment efficiency.

[0010] According to the above technical solution, a protective rod is slidably installed on the surface of the vertical sliding plate, and a protective hole is opened on the surface of the limiting rod. The protective rod contacts the protective hole, and the protective rod can prevent the hemostatic device from being accidentally disassembled due to accidental contact by personnel.

[0011] According to the above technical solution, a No. 3 spring is provided between the limiting rod and the vertical sliding plate, the moving plate is in contact with the hollow plate, the limiting rod passes through the surface of the placement frame, and the No. 3 spring can drive the limiting rod to reset.

[0012] According to the above technical solution, the limiting device includes a groove, a fixing rod, a fixing plate, non-woven fabric, Velcro, a linkage frame, a connecting block, a cylindrical rod, and a T-shaped plate. The movement of the fixing rod gradually loosens the non-woven fabric and Velcro, further facilitating the disassembly of the hemostatic device. The adjusting plate has a groove on its surface. The fixing rod is slidably installed at the bottom of the inner wall of the groove. The fixing plate is fixedly installed at the top of the fixing rod. The surface of the fixing rod is covered with non-woven fabric. The Velcro is fixedly installed on the surface of the non-woven fabric. The linkage frame is fixedly installed on the surface of the vertical sliding plate. The connecting block is fixedly installed on the surface of the linkage frame. The cylindrical rod is fixedly installed at the bottom of the connecting block. The T-shaped plate is fixedly installed on the surface of the fixing rod. A circular hole is provided on the surface of the T-shaped plate. As the straps or adhesive pads gradually loosen, medical personnel can more easily disassemble them for replacement or adjustment. This is crucial for situations where the hemostatic device needs to be replaced during treatment, improving operational flexibility and efficiency.

[0013] According to the above technical solution, the cylindrical rod contacts the circular hole, and a No. 4 spring is provided between the groove and the fixed rod, which can drive the fixed rod to reset.

[0014] A method for adjusting an adjustable pressure hemostatic device includes: Step 1: Place the body part that needs to be stopped on the surface of the rubber sheet, and secure the rubber sheet and the part to be stopped by wrapping non-woven fabric and Velcro. Step 2: Manually pull the slide bar upward to release the limit on the limiting groove, allowing the threaded rod to rotate freely; Step 3: Manually rotate the rotating plate to drive the threaded rod to rotate. The threaded rod rotates and moves downward due to the pressure of the rotating groove. Step 4: Move the threaded rod downwards to compress the pressure bladder downwards, thus adjusting the pressure at the hemostatic site.

[0015] This invention provides an adjustable pressure hemostasis device and adjustment method. It has the following beneficial effects: (1) The adjustable pressure hemostasis device moves slowly downward by being squeezed by the rotating groove through the rotation of the threaded rod. The slow downward movement of the threaded rod squeezes the pressure airbag to move downward. The slow downward movement of the pressure airbag adjusts the pressure at the hemostasis site. The slow adjustment allows medical staff to make individualized pressure adjustments according to the specific condition of the patient. Different patients may have different physiological conditions and wound conditions. Therefore, the slow adjustment can more accurately adapt to different treatment needs.

[0016] (2) This adjustable pressure hemostatic device moves the extension plate upward by moving the vertical slide plate upward, which in turn moves the threaded rotating rod upward. The threaded rotating rod then disengages from the pressure bladder, achieving the effect of rapid disassembly of the hemostatic device. In some emergency situations, rapid medical intervention is required. The ability to quickly disassemble the hemostatic device allows medical staff to treat patients more quickly, reducing waiting time and improving treatment efficiency.

[0017] (3) After the T-shaped plate is released, the fixed rod moves away from the placement frame under the elastic force of the No. 4 spring. The movement of the fixed rod causes the non-woven fabric and Velcro to gradually loosen, which makes it easier to disassemble the hemostatic device. If the bandage or adhesive strip gradually loosens, medical staff can disassemble it more easily for replacement or adjustment. This is very important for situations where the hemostatic device needs to be replaced during treatment, and can improve the flexibility and efficiency of operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-3One embodiment of the present invention is: an adjustable pressure hemostasis device and adjustment method, comprising an adjustment plate 1 and an adjustment device, wherein a placement plate 2 is fixedly installed on the top of the adjustment plate 1, a rubber plate 6 is hingedly installed on the bottom of the adjustment plate 1, and a support frame 7 is fixedly installed on the top of the placement plate 2. The adjustment device includes a placement frame 31, a vertical sliding plate 32, an extension plate 33, a limiting ring 34, a limiting groove 35, a threaded rotating rod 36, a rotating plate 37, a hollow cylinder 38, a sliding rod 39, a slider 310, a pressure airbag 311, and a return spring 312. The threaded rotating rod 36 rotates and is squeezed downward by the rotating groove, causing the pressure airbag 311 to move downward, thus adjusting the pressure at the hemostasis site. The placement frame 31 is fixedly installed on the top of the adjustment plate 1, and the vertical sliding plate 32 is slidably installed on... An extension plate 33 is fixedly installed on the top of a vertical sliding plate 32 on the inner wall of the placement rack 31. A limiting ring 34 is fixedly installed on the top of the extension plate 33, and a limiting groove 35 is formed on the surface of the limiting ring 34. An extension hole is formed on the surface of the extension plate 33. A threaded rotating rod 36 is rotatably installed on the inner wall of the extension hole. A rotating plate 37 is fixedly installed on the top of the threaded rotating rod 36. A hollow cylinder 38 is fixedly installed on the bottom of the rotating plate 37. A sliding rod 39 is slidably installed on the inner wall of the hollow cylinder 38. A slider 310 is slidably installed on the bottom of the adjusting plate 1. A pressure airbag 311 is fixedly installed on the surface of the slider 310. A return spring 312 is provided between the slider 310 and the adjusting plate 1. Slow adjustment allows medical staff to make individualized pressure adjustments according to the specific condition of the patient. Different patients may have different physiological conditions and wound conditions. Therefore, slow adjustment can more accurately adapt to different treatment needs.

[0022] A first spring is provided between the slide rod 39 and the hollow cylinder 38. The rotating plate 37 is in contact with the limiting groove 35. An adjustment hole is provided on the surface of the adjusting plate 1. The slide rod 39 can be reset by the first spring.

[0024] In this embodiment, the body part requiring hemostasis is placed on the surface of the rubber plate 6. The rubber plate 6 and the part to be hemostatically stopped are fixed by wrapping non-woven fabric 54 and Velcro 55. After the hemostatic part is fixed, when it is necessary to adjust the pressure of the hemostatic device, the slide bar 39 is manually pulled upward. The upward movement of the slide bar 39 releases the limit on the limiting groove 35, allowing the threaded rotating rod 36 to rotate freely. After the threaded rotating rod 36 can rotate freely, the rotating plate 37 is manually rotated. The rotation of the rotating plate 37 drives the threaded rotating rod 36 to rotate. The threaded rotating rod 36 is squeezed downward by the rotating groove. The downward movement of the threaded rotating rod 36 squeezes the pressure airbag 311 downward, and the downward movement of the pressure airbag 311 adjusts the pressure of the hemostatic part.

[0025] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a disassembly device and a limiting device. The disassembly device includes a placement rod 41, a moving plate 42, a hollow plate 43, a limiting rod 44, a polygonal plate 45, and an arc-shaped spring piece 47.

In some emergency situations, rapid medical intervention is required. The ability to quickly disassemble the hemostatic device allows medical personnel to treat patients more quickly, reducing waiting time and improving treatment efficiency.

[0026] A protective rod 46 is slidably mounted on the surface of the vertical sliding plate 32. A protective hole is opened on the surface of the limiting rod 44. The protective rod 46 contacts the protective hole. The protective rod 46 can prevent the hemostatic device from being accidentally disassembled due to accidental contact by personnel.

[0027] A No. 3 spring is provided between the limiting rod 44 and the vertical slide plate 32. The moving plate 42 contacts the hollow plate 43. The limiting rod 44 passes through the surface of the placement frame 31. The No. 3 spring can drive the limiting rod 44 to reset.
