Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a distal radial artery hemostat. Background Technology

[0002] In recent years, with the emergence of smaller and thinner-walled sheaths, researchers have begun to explore puncture routes for distal blood vessels. Studies by scholars at home and abroad have confirmed that distal radial artery access via the anatomical location of the nasal cavity or Hegu acupoint is equally safe and effective. It is more comfortable for the wearer during the procedure. The distal radial artery is located superficially with more surrounding bony structures, which is conducive to puncture point location and postoperative compression hemostasis. Furthermore, the postoperative compression time and the incidence of complications are significantly reduced.

[0003] Currently, common methods for hemostasis after distal radial artery puncture mainly include manual compression and tourniquet application. Manual compression is a direct method of hemostasis. After the procedure, the puncture site is covered with sterile gauze or cotton balls, and then pressure is applied to the distal radial artery with a finger. It is crucial to ensure moderate pressure to achieve hemostasis while avoiding excessive pressure that could damage the vessel; this method is cumbersome and requires careful operation. Tourniquet application, similar to a bandage, achieves hemostasis by applying pressure around the puncture site, but it does not provide concentrated pressure at the puncture site.

[0004] For example, Chinese utility model patent CN218979071U discloses a distal radial artery hemostat. It includes a support plate with a compression bladder embedded in its center. A marking ring is located on the outer wall of the compression bladder. An inflation tube is fixedly connected to the bottom of the compression bladder, and a small bladder is fixedly connected to the bottom of the inflation tube. An inflation valve is fixedly connected to the bottom of the small bladder, and a guide tube is fixedly connected to the bottom of the inflation valve. A pressure edge is provided at the connection between the inflation tube, the compression bladder, and the small bladder, making the puncture point more obvious and better conforming to the hand shape at the puncture point. However, the wristband described is fixed, integrated with the main body of the hemostat, and its angle and length are fixed. This makes it impossible to precisely adjust and securely fix the wristband according to the hand shape when applying pressure for hemostasis to people of different ages and hand shapes. Furthermore, it can only be removed by prying open the Velcro strap placed in the palm, which can cause pain to the wearer when their hand is not easily movable. The airbag described is located in the center and provides pressure, but there is no fixed component to compress it. The overall pressure is higher than that of a bandage, but not significantly higher. Additionally, there is a small airbag at the gas inlet area, which remains inflated for extended periods during product wear, posing a risk of leakage.

[0005] Therefore, there is a need for a hemostat designed for the distal radial artery puncture site, which can provide concentrated pressure and is easy to use. Utility Model Content

[0006] To address the problems of cumbersome operation, inconvenient fixation and disassembly, and inability to provide concentrated pressure in existing distal radial artery puncture hemostasis methods, this utility model provides a distal radial artery hemostat.

[0007] To achieve the objectives of this utility model, the technical solution adopted is as follows:

[0008] A distal radial artery hemostat includes a main board, an air bladder, a wristband, and a connector. The wristband includes a first wristband and a second wristband. The edge of the main board extends outward and has a first protrusion, a second protrusion, and a third protrusion. The connector is connected to the air bladder through a connecting tube. The air bladder is installed on one side of the main board by heat sealing. The first wristband is installed at the position of the first protrusion, and the second wristband is installed at the position of the second protrusion. A first arc segment is provided between the first protrusion and the third protrusion. The main board also has a marking position.

[0009] Based on the above technical solution, a second arc segment is further provided between the first convex part and the second convex part.

[0010] Based on the above technical solution, further, the first protrusion has a first opening, the second protrusion has a second opening, one end of the first wristband passes through the first opening for detachable fixation, and one end of the second wristband passes through the second opening for detachable fixation.

[0011] Based on the above technical solution, further, the opening length of the first opening is shorter than the opening length of the second opening, and the opening lengths of the first opening and the second opening are in the range of 4mm-5mm.

[0012] Based on the above technical solution, the first wristband further includes a wide band and a narrow band, and the wide band and the narrow band are integrally formed.

[0013] Based on the above technical solution, the airbag is further provided with a gas interface, which is connected to one end of a connecting tube, and the inside of the connecting tube is in communication with the inside of the airbag.

[0014] Based on the above technical solution, the included angle of the first arc segment is further defined as 100°-125°.

[0015] Based on the above technical solution, the included angle of the second arc segment is further defined as 105°-120°.

[0016] Based on the above technical solution, both the first and second wristbands are Velcro straps with integrated hook and loop fasteners.

[0017] Furthermore, based on the above technical solution, the connector is a pinless connector.

[0018] Compared with the prior art, the beneficial effects of this utility model are specifically reflected in the following aspects:

[0019] (1) This utility model heat-connects an airbag to one side of the main board. When gas is introduced into the airbag, the airbag expands and contacts the main board. The main board provides support for the airbag, which can effectively provide concentrated pressure on the distal radial artery puncture point. Furthermore, the connector connected to the airbag is a needleless connector, which can avoid the risks of the spring itself not being able to rebound in the existing structure and increase the safety of hemostasis.

[0020] (2) The wristband in this invention uses a hook-and-loop Velcro closure, which can be easily attached by the operator. Furthermore, the mainboard has markings, allowing the wearer to easily write the usage time on it, facilitating time recording and allowing for periodic deflation and decompression. Additionally, the lengths of the holes on the mainboard for connecting the strap are appropriately designed, allowing the wristband to be freely adjusted according to actual needs, making it more comfortable for the wearer's hand and improving its stability.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0030] Example

[0031] Combination Figures 1-4 As shown, this embodiment provides a distal radial artery hemostat, including a main board 2, an air bladder 1, a wristband 5, and a connector 3. The wristband 5 includes a first wristband 51 and a second wristband 52, which are mounted on the main board 2. In this embodiment, the air bladder 1 is fixed to one side of the main board 2 by heat sealing, and the connector 3 is connected to the interior of the air bladder 1 via a connecting tube 4. The main board 2 is designed according to the shape of a hand, and its edge extends outward with a first protrusion 7, a second protrusion 8, and a third protrusion 9. Preferably, a first arc segment is provided between the third protrusion 9 and the first protrusion 7, and the included angle B of the first arc segment is preferably 100°-125°, more preferably 110°. A second arc segment is provided between the first protrusion 7 and the second protrusion 8, and the included angle A of the second arc segment is preferably 105°-120°. It should be noted that the included angle of each arc segment is the angle between the two tangents drawn from the left and right ends of the arc segment. Figure 2 and Figure 4 The dashed lines in the diagram represent lines that are not directly displayed, and are used to more directly represent the structure.

[0032] Furthermore, the first protrusion 7 has a first opening 53, and the second protrusion 8 has a second opening 54. One end of the first wristband 51 passes through the first opening 53 for detachable fixation, and one end of the second wristband 52 passes through the second opening 54 for detachable fixation. It should be noted that the heat sealing method includes, but is not limited to, heat pressing heat sealing, heat sealing heat sealing, etc.; both the first wristband 51 and the second wristband 52 can be a hook and loop fastener structure, which can be self-adhesive to achieve quick connection. After hemostasis is completed, the hook and loop fastener at the connection point with the corresponding protrusion of the motherboard 2 can be directly peeled off for quick disassembly; the connector 3 is preferably a needleless connector.

[0033] In this embodiment, an identifier 6 can also be set on one side of the motherboard 2, for example... Figure 2 The bracket structure printed in the center allows the wearer to directly write the usage time on the marking position 6, facilitating time recording and enabling timed deflation and decompression operations. Furthermore, the mainboard 2 is made of a soft material, which, while providing support for the airbag 1, can also adapt to the wearer's hand shape, conforming to the back of the hand and reducing discomfort caused by excessive pressure and friction on the wearer's hand.

[0034] In this embodiment, the length of the opening of the first opening 53 is shorter than the length of the opening of the second opening 54, and the preferred lengths of the openings of the first opening 53 and the second opening 54 are 4-5mm, allowing the first wristband 51 and the second wristband 52 to be adjusted left and right within the corresponding openings, with an adjustment range of 15 degrees to the left and right. It should be noted that, referring to... Figure 2 As shown in the attached diagram, the adjustment here refers to the angle X, which is 15 degrees, in which the first wristband 51 and the second wristband 52 are slightly adjusted left and right in the first opening 53 and the second opening 54, respectively. It can be adjusted according to the size of the wearer's hand to make it fit the wearer's hand better and improve the fixation effect.

[0035] In this embodiment, the first wristband 51 includes a wide band and a narrow band, which are integrally formed. The narrow band passes through the first opening 53, and the wide band is located away from the first opening 53. It should be noted that the purpose of designing the first wristband 51 with a wide and narrow structure is to reduce friction between the narrow band and the index finger and thumb on both sides of the wristband when the narrow band passes over the web of the wearer's hand, thereby reducing the wearer's discomfort.

[0036] In this embodiment, the airbag 1 is equipped with a gas interface, which is connected to one end of the connecting tube 4, and the interior of the connecting tube 4 is in communication with the interior of the airbag 1. The other end of the connecting tube 4 is connected to a needleless connector. Furthermore, the interior of the needleless connector is made of silicone, unlike existing one-way valves on the market that use springs for gas check. Common hemostasis processes require multiple gas extractions for depressurization, and the spring may become stuck or fail to spring back after repeated use. This needleless connector avoids the risk of the spring failing to spring back after repeated use, thus increasing the safety of hemostasis.

[0037] Operating principle: Refer to Figure 4 As shown, after attaching the distal radial artery hemostat to the distal radial artery puncture point on the hand, the wristband 5 is wrapped around the back of the hand and then attached to each other using the properties of Velcro, allowing the wearer to perform the operation independently.

[0038] The above are merely embodiments of this utility model, described in a relatively specific and detailed manner, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
