Description

Technical Field

[0001] This application relates to the field of medical technology, and in particular to a distal radial artery compression hemostat. Background Technology

[0002] The distal radial artery, as an important component of the human circulatory system, is frequently a target for interventional diagnostic and therapeutic procedures, especially in the diagnosis and treatment of cardiovascular diseases. The puncture site for distal radial artery puncture is located at the angle between the extensor pollicis brevis and extensor pollicis longus tendons, known as the snuffbox area. Distal radial artery puncture is widely used in clinical practice due to its simplicity and high patient comfort. However, bleeding often occurs at the puncture site after this procedure. If hemostasis is not timely and effective, it can lead to excessive blood loss and even other complications, seriously affecting the patient's postoperative recovery and quality of life.

[0003] For bleeding at the distal radial artery puncture site, current clinical practice mainly relies on conventional methods such as applying pressure with gauze or using bandages to apply pressure for hemostasis. While these methods can control bleeding to some extent, they have several shortcomings. Gauze pressure requires continuous application by medical staff, increasing their workload and making it difficult to ensure a stable and prolonged compression effect. While bandages can create some pressure, it is often difficult to precisely control the intensity and extent of the pressure, potentially obstructing blood circulation in the patient's hand and causing discomfort such as pain and numbness.

[0004] Therefore, there is a need for a distal radial artery compression hemostat that can stably and accurately compress the distal radial artery puncture site while being easy and quick to install. Utility Model Content

[0005] In view of this, it is necessary to provide a distal radial artery compression hemostat that can stably and accurately compress the distal radial artery puncture site while being easy and quick to install, in order to solve the above problems.

[0006] Embodiments of this application provide a distal radial artery compression hemostat, used at the puncture site after distal radial artery puncture, comprising:

[0007] A fixing strap is wrapped around the junction of the wrist and the web of the hand. The fixing strap includes a first wrist strap, a second wrist strap, and a web of the hand strap.

[0018] In at least one embodiment of this application, the distal radial artery compression hemostat further includes an inflation assembly connected to the air bladder for inflating and deflating the air bladder.

[0019] In at least one embodiment of this application, the inflation assembly includes a connecting pipe, a connector, and an inflator. One end of the connecting pipe is connected in parallel to the airbag, and the other end is connected to the connector. When the inflator is inserted into the connector, the inflator communicates with the airbag and inflates or deflates the airbag.

[0020] In at least one embodiment of this application, the airbag is made of a soft, transparent material.

[0021] In at least one embodiment of this application, the fixing strap is made of a soft and transparent material.

[0035] Embodiments of this application provide a distal radial artery compression hemostat, used at the puncture site after distal radial artery puncture, comprising:

[0036] A fixing strap is wrapped around the junction of the wrist and the web of the hand. The fixing strap includes a first wrist strap, a second wrist strap, and a web of the hand strap. One end of the first wrist strap, the second wrist strap, and the web of the hand strap all converge to form a fixing area.

[0037] An airbag is placed on the fixed area and compresses the distal radial artery puncture site;

[0038] The first wristband has a first Velcro closure at the end away from the airbag, the second wristband has a second Velcro closure at the end away from the airbag, and the web-shaped strap has a third Velcro closure at the end away from the airbag. In use, the first and second wristbands are wrapped around the wrist, and the web-shaped strap is located at the web of the hand. The first and second Velcro closures are connected, and the third Velcro closure is connected to the second Velcro closure, so that the first wristband, the second wristband, and the web-shaped strap form a closed loop.

[0039] The aforementioned distal radial artery compression hemostat uses a balloon to compress the distal radial artery puncture site, providing stable and precise pressure to effectively control bleeding and reduce the risk of complications caused by improper compression. The balloon is positioned at the junction of the wrist and the web of the hand via a fixing strap, and the first wrist strap, second wrist strap, and web strap are connected in pairs via Velcro, forming a closed-loop structure. This structure effectively compresses the puncture site while avoiding excessive pressure on other parts of the hand, thus ensuring unobstructed blood circulation in the patient's hand and reducing discomfort such as pain and numbness. Simultaneously, the use of Velcro facilitates quick donning and removal of the hemostat by medical personnel, improving operational efficiency.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] according to Figures 1-6 This application provides a distal radial artery compression hemostat 100, which is used at the puncture site after distal radial artery puncture, and includes: an airbag 10 and a fixation strap 20.

[0042] The fixing strap 20 is wrapped around the junction of the wrist and the web of the hand. The fixing strap 20 includes a first wrist strap 21, a second wrist strap 22, and a web of the hand strap 23. One end of each of the first wrist strap 21, the second wrist strap 22, and the web of the hand strap 23 intersects to form a fixing area 40. An air bladder 10 is disposed on the fixing area 40 to compress the distal radial artery puncture site. The first wristband 21 has a first Velcro 211 at the end away from the airbag 10, the second wristband 23 has a second Velcro 221 at the end away from the airbag 10, and the web-shaped strap 23 has a third Velcro 231 at the end away from the airbag 10. In use, the first wristband 21 and the second wristband 22 are wrapped around the wrist, and the web-shaped strap 23 is located at the web of the hand. The first Velcro 211 is connected to the second Velcro 221, and the third Velcro 231 is connected to the second Velcro 221, so that the first wristband 21, the second wristband 22, and the web-shaped strap 23 are connected to form a closed loop.

[0043] Specifically, the distal radial artery puncture site is at the angle between the extensor pollicis brevis tendon and the extensor pollicis longus tendon. The balloon 10 is directly compressed at the distal radial artery puncture site. As the core compression component, the balloon 10 generates uniform pressure by inflating and applying appropriate pressure to the puncture site, effectively preventing blood from flowing out of the puncture site, thereby achieving stable hemostasis and reducing the workload of medical staff.

[0044] Furthermore, the fixation strap 20 consists of a first wrist strap 21, a second wrist strap 22, and a thenar eminence strap 23. One end of each strap intersects to form a fixation area 40 for placing the airbag 10, while the other end is equipped with hook and loop fasteners for connecting to form a closed loop. The hook and loop fasteners can be secured to the fixation strap 20 by suturing, heat fusion bonding, or other methods. The connection of the hook and loop fasteners allows for graded adjustment of the axial tension of the airbag 10, ensuring stable fixation of the airbag 10 at the puncture site and preventing displacement or detachment of the airbag 10 due to patient movement. The first wrist strap 21 and the second wrist strap 22 form a ring-shaped fixation base at the wrist, and the addition of the thenar eminence strap 23 disperses the pressure points of the airbag 10, improving patient comfort.

[0045] In summary, the balloon 10 is accurately placed at the distal radial artery puncture site. Then, the first wrist strap 21 and the second wrist strap 22 are wrapped around the wrist, and the web strap 23 is fitted against the web of the hand. The first wrist strap 21 and the second wrist strap 22 are connected using the first Velcro 211 and the second Velcro 221, and the web strap 23 and the second wrist strap 22 are connected using the third Velcro 231, forming a closed loop. The pressure of the balloon 10 is adjusted by inflating or deflating to ensure hemostasis. The tightness of the fixing strap 20 can be adjusted by changing the connection length of the Velcro straps as needed, ensuring the balloon 10 is stable and the patient is comfortable. This achieves precise and stable pressure at the puncture site while ensuring patient comfort and ease of operation for medical staff.

[0046] In one specific embodiment, the fixing strap 20 includes a first surface 20a and a second surface 20b opposite to the first surface 20a, the first hook and loop fastener 211 is disposed on the first surface 20a, and the third hook and loop fastener 231 is disposed on the second surface 20b; the second hook and loop fastener 221 includes a first adhesive surface 2211 and a second adhesive surface 2212 opposite to the first adhesive surface 2211, the first adhesive surface 2211 is disposed on the first surface 20a, and the second adhesive surface 2212 is disposed on the second surface 20b.

[0047] Specifically, the double-sided design of the fixing strap 20 allows the hook and loop fasteners to be arranged on two independent and opposite surfaces, thereby increasing the flexibility of hook and loop fastener arrangement and space utilization.

[0048] Furthermore, the first hook and loop fastener 211 is located on the first surface 20a of the first wristband 21, and is used to connect with the second hook and loop fastener 221 of the second wristband 22, forming a preliminary closed-loop structure at the wrist. The second hook and loop fastener 221 of the second wristband 22 includes a first adhesive surface 2211 and a second adhesive surface 2212, which are located on the first surface 20a and the second surface 20b of the fixing strap 20, respectively. This allows the second hook and loop fastener 221 of the second wristband 22 to connect simultaneously with the first hook and loop fastener 211 of the first wristband 21 and the third hook and loop fastener 231 of the web-like strap 23, thereby achieving a seamless connection between the second wristband 22 and the first wristband and the web-like strap 23. The third hook and loop fastener 231 is located on the second surface 20b of the web-like strap 23, and is used to connect with the second hook and loop fastener 221 on the second wristband 22, thereby fixing the connection between the web-like strap 23 and the second wristband 22.

[0049] In one specific embodiment, the airbag 10 is provided with a compression protrusion 11 corresponding to the puncture site. The compression protrusion 11 has a ring-shaped cross-section and a transparent observation area 12 is formed in the center.

[0050] Specifically, when the balloon 10 aligns with the puncture site, inflation of the balloon 10 causes it to expand, and the pressure protrusion 11 on its surface also expands, forming a convex structure. This structure directly aligns with and compresses the distal radial artery puncture site, adhering to and compressing the surrounding tissue, providing concentrated local pressure. This avoids excessive or insufficient pressure, thereby improving hemostasis and reducing damage to surrounding tissues. The pressure protrusion 11 has a ring-shaped cross-section, allowing it to apply pressure evenly around the puncture site. A transparent observation area 12 is designed in the center of the pressure protrusion 11, facilitating direct observation of hemostasis and skin condition by medical personnel. The transparent observation area 12 allows medical personnel to monitor the hemostasis effect and patient skin condition in real time without removing the hemostat, reducing operational interference and improving diagnostic and treatment efficiency.

[0051] In one specific embodiment, the first wristband 21, the second wristband 22, and the thumb strap 23 are integrated at the end near the airbag 10.

[0052] Specifically, the integrated structure near the airbag 10 avoids the problems of intertwining and misalignment of the fixing straps 20 when the first wrist strap 21, the second wrist strap 22, and the thenar eminence strap 23 are wrapped around the airbag 10, reducing wasted emergency time due to these issues. Furthermore, the integrated structure near the airbag 10 can more evenly distribute the pressure of the airbag 10 to the wrist and thenar eminence area, avoiding excessive or insufficient local pressure caused by uneven force distribution from separate straps, thereby improving patient comfort.

[0053] Furthermore, after aligning the airbag 10 with the puncture site, the integrated first wrist strap 21, second wrist strap 22, and the web space strap 23 naturally conform to the anatomical structure of the wrist and web space. The three straps are wrapped around the wrist and web space respectively and secured with Velcro, without requiring additional adjustment to the connection position between the straps and the airbag 10. After the airbag 10 is inflated, the integrated structure of the securing straps evenly transmits pressure to the wrist and web space areas, ensuring precise pressure from the airbag at the puncture site.

[0054] In one specific embodiment, the included angle between the first wristband 21 and the second wristband 22 is denoted as A, the included angle between the second wristband 22 and the thumb-and-shoulder strap 23 is denoted as B, and the included angle between the first wristband 21 and the thumb-and-shoulder strap 23 is denoted as C, satisfying the following relationships: 90°>A>180°; 90°>B>140°; 90°>C>140°.

[0055] Specifically, the angles between the second wristband 22 and the web-like area band 23, and between the first wristband 21 and the web-like area band 23, are designed to ensure that unnecessary pressure or discomfort is not placed on the web-like area when worn. The angled design, conforming to the hand shape, reduces pressure on the wrist and improves wearing comfort. Angle B allows the web-like area band 23 to adapt to the anatomical structure between the wrist and the web, providing stable support. Angle C ensures that the connection between the first wristband 21 and the web-like area band 23 adapts to the anatomical structure between the wrist and the web, providing stable support. The angle between the first wristband 21 and the second wristband 22 creates an appropriate coverage area when wrapped around the wrist, neither too loose nor too tight.

[0056] In one specific embodiment, the distal radial artery compression hemostat further includes an inflation component 30, which is connected to the airbag 10 and is used to inflate and deflate the airbag 10.

[0057] Specifically, the inflation assembly 30 is responsible for inflating and deflating the airbag 10, ensuring that the airbag 10 can quickly and accurately reach the predetermined pressure level according to treatment needs. The inflation assembly 30 is connected to the airbag 10 through a specific interface or pipe to form a closed airway system, thereby ensuring that gas can be smoothly and leak-free transferred from the inflation assembly 30 to the airbag 10, while also allowing the gas inside the airbag 10 to be released quickly when needed.

[0058] In one specific embodiment, the inflation assembly 30 includes a connecting pipe 31, a connector 32, and an inflator 33. One end of the connecting pipe 31 is connected in parallel to the airbag 10, and the other end is connected to the connector 32. When the inflator 33 is inserted into the connector 32, the inflator 33 communicates with the airbag 10 and inflates or deflates the airbag 10.

[0059] Specifically, connector 32 is an inflation valve, and inflator 33 is used to control the inflation and deflation of gas. By operating inflator 33, the airbag 10 can be expanded and contracted. One end of connecting tube 31 is connected to airbag 10 to ensure that gas can enter the airbag 10; the other end is connected to connector 32 to provide an interface for inflator 33 to be connected.

[0060] Furthermore, the parallel arrangement of the connecting tube 31 and the airbag 10 ensures that when the fixing strap 20 is in contact with the airbag 10, the connecting tube 31 will not be squeezed or twisted due to the inflation and expansion of the airbag 10, thus affecting the gas transmission efficiency. The parallel arrangement of the connecting tube 31 reduces the pressure and discomfort on the skin, improving the user's wearing comfort.

[0061] In one specific embodiment, the airbag 10 is made of a soft, transparent material.

[0062] Specifically, the airbag 10 is made of a soft rubber material, which typically possesses good flexibility and elasticity, allowing it to deform under external force during inflation and quickly return to its original shape. This characteristic enables the airbag 10 to fit closely to the patient's skin, providing even and stable pressure for effective hemostasis. The transparent design of the airbag 10 allows doctors or patients to directly observe the condition of the compressed area, such as whether bleeding has stopped and whether the skin color is normal, without removing the airbag 10. This is crucial for the timely detection and management of potential complications.

[0063] Furthermore, through the inflation component 30 connected to the airbag 10, an appropriate amount of gas is injected into the airbag 10, causing it to expand to a level sufficient to provide stable pressure. The airbag 10 deforms under the action of external force, and the airbag 10 expands, forming a pressure protrusion 11 on the surface of the airbag 10. The pressure protrusion 11 fits against the puncture site, and the interior of the airbag 10 expands to form a transparent observation area 12. The condition of the compressed area can be observed through the transparent observation area 12, such as whether the bleeding has stopped and whether the skin color is normal.

[0064] In one specific embodiment, the fixing strap 20 is made of a flexible and transparent material.

[0065] Specifically, the fixation strap 20 is made of a soft and transparent material, designed for better skin contact and good transparency. Softness also means that the fixation strap 20 can better adapt to different patient body shapes and skin conditions. Depending on the patient's size and build, Velcro is used to connect the fixation straps 20. The tension applied to the fixation strap 20 adjusts its stability at the distal radial artery puncture site, and the tightness of the fixation strap 20 can be adjusted as needed.

[0066] In one specific embodiment, during use, when the first side 20a faces the human skin, the third hook and loop fastener 231 is first connected to the first adhesive side 2211, and the first hook and loop fastener 211 is then connected to the second adhesive side 2212; or when the second side 20b faces the human skin, the first hook and loop fastener 211 is first connected to the second adhesive side 2212, and the first adhesive side 2211 is then connected to the third hook and loop fastener 231.

[0067] Example 1: In use, when the first side 20a faces the human skin, the third hook and loop fastener 231 first connects to the first adhesive side 2211, and then the first hook and loop fastener 211 connects to the second adhesive side 2212.

[0068] Specifically, the first side 20a and the second side 20b of the fixing strap 20 are designed to face the human skin or the outside, and the different orientations of the fixing strap 20 can meet the needs of left-handed and right-handed users.

[0069] When the user places the first side 20a of the fixation strap 20 towards the skin, the first Velcro 211 and the first adhesive side 2211 of the second Velcro 221 on the first side 20a also face towards the skin. The airbag 10 is accurately placed at the distal radial artery puncture site. Then, the first wrist strap 21 and the second wrist strap 22 are wrapped around the wrist, and the thenar eminence strap 23 is fitted against the thenar eminence. The third Velcro 231 on the second side 20b of the thenar eminence strap 23 first adheres to the portion connected to the first adhesive side 2211, forming a preliminary fixation structure. At this time, the thenar eminence strap 23 is first connected to the second wrist strap 22. After connection, the airbag 10 is inflated using the inflator 33 of the inflation assembly 30, causing the pressure generated by the inflated airbag 10 to be evenly distributed around the puncture site. This is because the connected components provide a stable support structure for the airbag 10, allowing the pressure to be transmitted in the designed direction and range. Subsequently, the first Velcro 211 of the first wristband 21 is wrapped around one side of the wrist and tightly connected to the second adhesive surface 2212, thus connecting the second wristband 22 to the first wristband 21 and completing the final fixation and fit adjustment. After the first wristband 21 and the second wristband 22 are connected, the pressure distribution of the airbag 10 can be finely adjusted. By adjusting the tightness of the connection between the two wristbands, the degree of pressure exerted by the airbag 10 on the tissues surrounding the distal radial artery puncture site can be changed.

[0070] Example 2: When the second side 20b faces the human skin, the first Velcro 211 is first connected to the second adhesive side 2212, and then the first adhesive side 2211 is connected to the third Velcro 231.

[0071] Specifically, when the second side 20b of the fixation strap 20 faces the human skin, the third hook and loop fastener 231 on the second side 20b and the second contact surface 2212 of the second hook and loop fastener 221 also face the skin. The first hook and loop fastener 211 on the first wrist strap 21 first connects to the second contact surface 2212 on the second wrist strap 22. At this time, the web-like strap 23 first connects to the second wrist strap 22, ensuring the initial fixation between the wrist straps. After the first hook and loop fastener 211 connects to the second contact surface 2212, the first contact surface 2211 on the second wrist strap 22 then connects to the third hook and loop fastener 231 on the web-like strap 23, completing the closed-loop structure of the entire fixation strap 20. The structural features and usage method of the distal radial artery tourniquet provided in this embodiment can be referred to the relevant description in Embodiment 1, and will not be repeated here.

[0072] Therefore, the distal radial artery compression hemostat 100 provided above, through the airbag 10, applies pressure to the distal radial artery puncture site, providing stable and precise pressure, effectively controlling bleeding, and reducing the risk of complications caused by improper compression. The airbag 10 is positioned at the junction of the wrist and the web of the hand via a fixing strap 20, and connected in pairs via Velcro straps on the first wrist strap 21, the second wrist strap 22, and the web strap 23, forming a closed-loop structure. This structure effectively compresses the puncture site while avoiding excessive pressure on other parts of the hand, thus ensuring unobstructed blood circulation in the patient's hand and reducing discomfort such as pain and numbness. Simultaneously, the use of Velcro facilitates quick donning and removal of the hemostat by medical personnel, improving operational efficiency.

[0073] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
