Abstract
Description
Technical Field
[0001] This application relates to a radial artery hemostasis sandbag wristband, belonging to the field of medical auxiliary device technology. Background Technology
[0002] Radial artery angiography has become a mainstream diagnostic and treatment method for cerebrovascular diseases; radial artery blood sampling is also a routine procedure in the intensive care unit. Effective hemostasis at the radial artery puncture site is a key step in preventing complications. Traditional hemostasis methods mainly rely on manual compression, elastic bandages, or mechanical compression devices, but these methods have the following problems: (1) Uneven pressure can easily lead to ecchymosis, bleeding and hematoma at the puncture site, and the pressure effect is unstable; (2) The pressure point is inaccurate and the pressure force is difficult to control; (3) The mechanical devices are complex, the operation is complicated, and the manufacturing cost is high.
[0003] In view of the shortcomings of the existing technology, there is an urgent need for a radial artery hemostasis device that is simple in structure, provides uniform pressure, is comfortable to wear, allows for independent pressure adjustment, and is reusable. Utility Model Content
[0004] To address the aforementioned issues, this application proposes a radial artery hemostasis sandbag wristband. By incorporating a sand-filled bag divided into several honeycomb-shaped grids, an arc-shaped cover, and an adjustment structure, the stability and reliability of the hemostasis effect of the wristband are significantly improved.
[0005] According to one aspect of this application, a radial artery hemostasis sandbag wristband is provided, comprising: The wristband includes a compression zone and a non-compression zone; A sand-filled bag is disposed inside the compression area. The inner cavity of the sand-filled bag is divided into several honeycomb-shaped cells, and each honeycomb-shaped cell is filled with sand. An arc-shaped cover is disposed between the wristband and the sand filling bag; The adjustment mechanism is located on the outside of the non-compression zone.
[0006] Optionally, the wristband is an integral ring structure.
[0007] Optionally, the wristband includes an elastic portion and a non-elastic portion, with the compression area located on the non-elastic portion.
[0008] Optionally, the length of the elastic portion is 40-50% of the length of the wristband.
[0009] Optionally, the elastic portion is composed of an elastic fabric and a pleated body, wherein the pleated body wraps around the elastic fabric.
[0010] Optionally, the adjustment mechanism is a knob-and-tightening-line mechanism, including a knob and a tightening line, wherein the tightening line passes through the interior of the elastic portion and the knob is located on the outside of the elastic portion.
[0011] Optionally, the convex surface of the arc-shaped cover faces the wristband side, and the concave surface faces the sand filling bag side.
[0012] Optionally, the width of the arc-shaped cover is equal to the width of the sand filling bag.
[0013] Optionally, the length of the arc-shaped cover is equal to the length of the sand filling bag.
[0014] Optionally, the arc-shaped cover is a flexible arc-shaped sheet.
[0015] Optionally, the outer layer of the wristband and the outer layer of the sand filling bag are both made of PU leather.
[0016] The beneficial effects that this application may produce include, but are not limited to: 1. The radial artery hemostasis sandbag wristband provided in this application divides the wristband into functional zones, placing the sand-filled bag inside the compression zone so that the pressure can be concentrated on the puncture point area, while the adjustment mechanism is placed in the non-compression zone to avoid unnecessary traction or displacement of the puncture point when adjusting the tightness, thus improving the safety of wristband use.
[0017] 2. The radial artery hemostasis sandbag wristband provided in this application has a sand-filled bag whose inner cavity is divided into several honeycomb-shaped grids, each grid being independently filled with sand grains. When pressure is applied, it effectively restricts the lateral flow and accumulation of sand grains, avoiding the problem of excessively high or low local pressure caused by sand grain displacement in traditional single sandbags.
[0018] 3. The radial artery hemostasis sandbag wristband provided in this application has a knob-type tension cord mechanism for adjustment. The knob is located on the outside of the non-compression area of the wristband. Patients or medical staff can rotate the knob with one hand to tighten or loosen the tension cord, thereby achieving continuous and precise adjustment of the tightness of the wristband and the pressure of the sandbag.
[0019] 4. The radial artery hemostasis sandbag wristband provided in this application has an elastic part and a non-elastic part. The compression area is located on the non-elastic part. The elastic part is composed of elastic fabric and an outer pleated ring. The contraction line is only inserted inside the elastic part. When the knob is rotated to tighten, the contraction force is only applied to the elastic section, causing the pleated ring to fold and shorten evenly in the circumferential direction. The non-elastic compression section remains smooth because no contraction line passes through it. Attached Figure Description

[0028] refer to Figure 1-3 This application discloses an embodiment of a radial artery hemostasis sandbag wristband, comprising: The wristband 1 includes a compression zone and a non-compression zone; A sand-filled bag 2 is disposed inside the compression area. The inner cavity of the sand-filled bag 2 is divided into several honeycomb-shaped cells, and each honeycomb-shaped cell is filled with sand. An arc-shaped cover 3 is disposed between the wristband 1 and the sand filling bag 2; The adjustment mechanism is located on the outside of the non-compression zone.
[0029] This application divides the wristband 1 into functional zones and places the sand filling bag 2 inside the compression zone, so that the pressure can be concentrated on the puncture point area. The adjustment mechanism is placed in the non-compression zone to avoid unnecessary pulling or displacement of the puncture point when adjusting the tightness, thereby improving the safety of wristband use.
[0030] The sand-filled bag 2 is divided into several honeycomb-shaped compartments, which effectively restricts the lateral flow and accumulation of sand particles under compression, reducing the risk of subcutaneous hematoma, ecchymosis, or radial artery occlusion caused by uneven local pressure due to sand particle aggregation in traditional single sandbags. The synergistic effect of the sand particles in each independent compartment ensures a uniform pressure distribution transmitted to the puncture point throughout the sand-filled bag 2, while also exhibiting good adaptive shaping ability for the irregular curved surface of the wrist, achieving a stable and uniform compression hemostasis effect.
[0031] This application further provides an arc-shaped cover plate 3 as a stress transfer layer between the wristband 1 and the sand-filled bag 2, which converts the circumferential linear tension generated when the wristband 1 is tightened into a planar radial pressure acting on the sand-filled bag 2. This avoids the edge cutting effect or local stress concentration that may occur when the wristband 1 directly compresses the sand-filled bag 2, and makes the sand bag fit smoothly against the puncture point, thereby significantly improving the stability and reliability of the hemostasis effect.
[0032] The adjustment mechanism is located in the non-compression area of the wristband 1, which makes it easy for patients or medical staff to operate and adjust with one hand without touching the puncture area, reducing the risk of contaminating the puncture point or causing pain during the operation; at the same time, it avoids direct contact and interference between the adjustment mechanism and the sand filling bag 2 and the puncture point, ensuring the flatness of the compression area structure and the simplicity of the pressure.
[0033] refer to Figure 1 When using this hemostatic sandbag wristband, slip the wristband onto the patient's palm and slowly slide it to the appropriate position on the wrist. Align the sandbag 2 of the compression area with the patient's puncture area and adjust the adjustment mechanism to tighten the wristband 1 to a suitable degree, such as the tightness between the wristband and the skin of the wrist is just enough to insert 1-2 fingers, thereby achieving the function of pressure hemostasis.
[0034] Specifically, the honeycomb grid of the sand filling bag 2 is formed by stitching or hot pressing.
[0035] In one embodiment, the wristband 1 is an integral ring structure.
[0036] In this configuration, the integrated ring-shaped wristband 1 has no extra buckles or connectors, making it simple in structure and secure to wear. It can be operated with one hand and is not prone to slipping or shifting when the patient moves or changes position, ensuring that the sand filling bag 2 always accurately covers the puncture point.
[0037] In one embodiment, the wristband 1 includes an elastic portion 5 and a non-elastic portion 6, with the compression area located on the non-elastic portion 6.
[0038] In this configuration, the compression zone is located on the non-elastic part 6, which provides a non-deformable bearing platform for the sand filling bag 2 and the arc-shaped cover 3, ensuring that the pressure direction is vertical and stably directed towards the puncture point when tightening; while the elastic part 5 is responsible for providing circumferential shrinkage adjustment margin to achieve flexible adjustment.
[0039] In one embodiment, the length of the elastic portion 5 is 40-50% of the length of the wristband 1.
[0040] This ratio range ensures that the elastic part 5 has sufficient range of motion to accommodate the varying wrist circumferences of most adults, while also ensuring that the non-elastic part 6 occupies the main arc of the annulus, giving it sufficient length to cover the radial artery puncture point.
[0041] Specifically, the sand filling bag 2 is located in the compression zone, and the adjustment mechanism is located in the non-compression zone. The length ratio of the compression zone to the non-compression zone on the hemostatic sandbag wristband of this application is not specifically set, as long as the sand filling bag 2 is located in the non-elastic part 6 and the adjustment mechanism is located in the elastic part 5.
[0042] In one embodiment, the elastic portion 5 is composed of an elastic fabric and a pleated body 7, with the pleated body 7 wrapping around the elastic fabric.
[0043] In this setup, the elastic fabric provides basic resilience, while the outer pleated loops 7 (similar to the outer structure of a scrunchie) adapt to length changes by unfolding or folding the pleats themselves when tightening or loosening. This effectively prevents the elastic fabric from creating lateral marks or shearing friction against the skin when stretched, and also prevents the formation of messy, hard protrusions when tightened. The elastic fabric is not shown in the accompanying drawings.
[0044] Specifically, the interior of the non-elastic portion is made of non-elastic or low-elastic fabric.
[0045] In one embodiment, the adjustment mechanism is a knob 4 retractable cord mechanism, including a knob 4 and a retractable cord, wherein the retractable cord passes through the interior of the elastic portion 5 and the knob 4 is located on the outside of the elastic portion 5.
[0046] In this configuration, the shrinkage thread is threaded inside the elastic part 5, so that when the knob 4 is tightened, the contraction force acts only on the elastic part 5, causing the pleated coil 7 to fold and shorten evenly, while the non-elastic part 6 remains smooth and stationary because no shrinkage thread passes through it. The knob 4 is located on the outside of the elastic part 5, allowing the patient to fine-tune the pressure independently. The shrinkage thread is not shown in the attached diagram.
[0047] Specifically, the shrinkage thread is disposed inside the elastic part 5, and the two ends of the shrinkage thread are connected to the two ends of the elastic part 5 by means of sewing or heat pressing.
[0048] In one embodiment, the convex surface of the arc-shaped cover 3 faces the wristband 1, and the concave surface faces the sand filling bag 2.
[0049] In this configuration, the convex surface faces upward and abuts against the inner surface of the wristband 1, allowing the circumferential contraction force of the wristband 1 to be smoothly transmitted along the arched surface of the arc-shaped cover 3; the concave surface faces downward and covers the sand filling bag 2, allowing the pressure to be evenly distributed to the entire surface of the sand filling bag 2 after being gathered by the concave surface.
[0050] In one embodiment, the width of the arc-shaped cover 3 is equal to the width of the sand filling bag 2.
[0051] In one embodiment, the length of the arc-shaped cover 3 is equal to the length of the sand filling bag 2.
[0052] With this setting, the outer contour dimensions of the curved cover 3 and the sand filling bag 2 are consistent, which can avoid the local foreign body sensation or additional pressure marks caused by the edge of the curved cover 3 pressing directly on the skin next to the sand bag.
[0053] In one embodiment, the arc-shaped cover 3 is a flexible arc-shaped sheet.
[0054] In this configuration, the flexible material allows the curved cover 3 to undergo slight compliant deformation according to the physiological curvature of the patient's wrist when pressure is applied.
[0055] Specifically, the arc-shaped cover 3 can be made of medical-grade TPU material, medical-grade silicone rubber material, etc., as long as it meets the requirements.
[0056] In one embodiment, the outer layer of the wristband 1 and the outer layer of the sand filling bag 2 are both made of PU leather.
[0057] PU leather boasts excellent waterproof and abrasion-resistant properties, withstanding repeated alcohol wiping and disinfection without deterioration, meeting the infection control requirements of medical institutions for reusable devices. Simultaneously, PU leather is soft and smooth, with a low coefficient of friction when in contact with skin, reducing wear and pressure marks on the wrist skin caused by prolonged wear of the wristband.
[0058] Specifically, the wristband 1, the sand filling bag 2, the arc-shaped cover 3, and the adjustment mechanism can be combined by methods such as heat pressing and sewing, as long as the combination between the various structures can be achieved.
[0059] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
