Description

Technical Field

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

[0002] In recent years, with the advent of smaller and thinner-walled sheaths, researchers have begun to explore puncture routes for distal blood vessels. Studies have confirmed that distal radial artery access via the anatomical locations of the nasal cavity or Hegu acupoint is equally safe and effective, providing greater patient comfort during the procedure. The distal radial artery is located superficially with more surrounding bony structures, which facilitates puncture point localization and postoperative compression hemostasis. Furthermore, the postoperative compression time and incidence of complications are significantly reduced.

[0003] Currently, hemostasis in China mostly relies on elastic or adhesive bandages for compression, as there are no suitable products available. Bandages require multiple wrappings during the procedure, which is time-consuming and provides poor fixation and compression. The imported Terumo radial artery hemostat, with its injection-molded parts removed, can be used with difficulty, but its large size makes it impossible to achieve a good fit and fixation around the thenar eminence during hemostasis.

[0004] The prior art CN218979071U discloses a pneumatic distal radial hemostat, including a support plate with a compression pneumatic bladder embedded in the middle of the support plate. An inflation tube is fixedly connected to the bottom of the pneumatic bladder, and a small pneumatic bladder, an inflation valve, and a guide tube are connected in sequence. The compression pneumatic bladder is made of transparent material. Three fixing straps are provided on the support plate, and the support plate is fixed to the patient's hand by the three fixing straps. The fixing straps are integrated with the support plate, and the angle of the fixing straps is fixed. When applying pressure hemostasis to patients of different ages, sizes, and hand shapes, it is impossible to achieve precise adjustment and angle adjustment according to the hand shape.

[0005] Therefore, given that current distal hemostats are not effectively adapted to the actual user population, the clinical demand for a universal distal radial artery hemostat is becoming increasingly urgent. Utility Model Content

[0006] This invention solves the technical problems existing in the prior art and provides a distal radial artery balloon hemostat that can be adapted to different hand sizes.

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

[0008] A distal radial artery pneumatic hemostat includes a fixing ring, a main board, a pneumatic bladder, a first wristband, a second wristband, and a third wristband. The main board is internally connected to the fixing ring. The pneumatic bladder is disposed on one side wall of the main board. The first, second, and third wristbands are all slidably connected to the outer peripheral wall of the fixing ring. The ends of the first, second, and third wristbands away from the fixing ring are bonded together. The pneumatic bladder and the main board are both made of transparent, soft material.

[0009] Furthermore, three sliding grooves are provided on the outer peripheral wall of the fixing ring, and the three sliding grooves are spaced apart along the circumference of the fixing ring. The first wristband, the second wristband, and the third wristband are slidably connected in one of the sliding grooves.

[0010] Furthermore, one end of the first wristband, one end of the second wristband, and one end of the third wristband are each connected to a connecting block, and the first wristband, the second wristband, and the third wristband are slidably connected in the sliding groove through their respective connecting blocks.

[0011] Furthermore, the end of the second wristband away from the fixing ring is connected to the first hook and loop fastener, and the end of the third wristband away from the fixing ring is connected to the second hook and loop fastener. The first hook and loop fastener are bonded together, and the end of the first wristband away from the fixing ring extends between the first hook and loop fastener and the second hook and loop fastener. The first wristband is bonded to the first hook and loop fastener and the second hook and loop fastener.

[0012] Furthermore, the second wristband has a narrow portion and a wide portion, with the first Velcro fastener attached to the wide portion of the second wristband.

[0013] Furthermore, the third wristband has a narrow portion and a wide portion, and the second Velcro is attached to the wide portion of the third wristband.

[0014] Furthermore, the width of the first wristband is smaller than the width of the narrow portion of the second wristband, and the width of the first wristband is also smaller than the width of the narrow portion of the third wristband.

[0015] Furthermore, an indicator ring is provided at the center of the airbag.

[0016] Furthermore, a connecting tube is threaded through the fixing ring, one end of the connecting tube is connected to the inside of the airbag, and the other end of the connecting tube is connected to a connector.

[0017] Furthermore, the outer diameter of the fixing ring is in the range of 40-50mm.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The first, second, and third wristbands of this utility model are all slidably connected to the main board. When performing compression hemostasis on patients of different ages and hand shapes, the positions of the first, second, and third wristbands on the main board are adjusted according to the patient's hand shape. Each wristband can be adjusted 15° to the left and right on the main board. The position of each wristband can be adjusted at multiple angles and directions according to the size of the patient's hand, so that the three wristbands fit the patient's hand shape and the main board is firmly fixed to the patient's hand. This ensures that the position of the airbag corresponds to the puncture point and that the airbag will not move relative to the puncture point, ensuring the stability of the airbag position and firmly pressing the puncture point to ensure the hemostasis effect.

[0020] (2) This utility model is specifically designed for the shape of the tiger's mouth of the palm. The width of the first wristband can easily bypass the tiger's mouth area of ​​the user, and will not make deep contact with the base of the thumb and index finger, causing the first wristband to sink into the flesh, thus not causing discomfort to the patient. The second and third wristbands are designed to be narrow at the beginning and wide at the end. During the wearing process, the wide part of the second and third wristbands has a larger force-bearing area, which can disperse the force on the patient and reduce the patient's discomfort.

[0021] (3) The fixing ring of this utility model is designed to be 3 / 5 the size of a normal adult's palm. The overall product is small in size, which can reduce the discomfort caused to the patient when wearing it.

[0022] (4) The airbag and main board of this utility model are made of transparent material. An indicator ring is provided in the center of the airbag to facilitate observation of the position of the patient's puncture point, so that the airbag can accurately press the puncture point and improve the accuracy of the pressure. At the same time, the airbag and main board are made of lightweight and soft material, which can avoid causing discomfort to the patient.

[0023] (5) In this utility model, each wristband is slidably connected to the main board through a connecting block, and each wristband is fixedly connected to the connecting block by adhesive. The second wristband is provided with a first Velcro, and the third wristband is provided with a second Velcro. When fixing the first, second, and third wristbands, it is only necessary to insert the first wristband between the first and second Velcro to fix the three wristbands. Then, the position and angle of each wristband can be adjusted by the connecting block. The structure is simple, and there is no need to bind the wristbands to the main board, which is also convenient for patients to wear.

[0024] (6) The observation window is cut on the motherboard of this utility model. The airbag increases in size during the inflation process. The airbag squeezes the motherboard and obtains downward pressure feedback to the pressure point, which increases the pressure of the airbag on the pressure point. Attached Figure Description

Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] like Figure 1 , Figure 2As shown, this utility model provides a distal radial artery pneumatic hemostat, including a fixing ring 5, a main board 10, a pneumatic bladder 4, a first wristband 1, a second wristband 6, and a third wristband 7. The main board 10 is fixedly connected inside the fixing ring 5. The main board 10 is circular. The pneumatic bladder 4 is fixedly connected to one side of the main board 10 and is located at the center of the main board 10. The first wristband 1, the second wristband 6, and the third wristband 7 are all slidably connected to the outer peripheral wall of the fixing ring 5. The first wristband 1, the second wristband 6, and the third wristband 7 are spaced apart along the circumference of the fixing ring 5 and slide along the circumference of the fixing ring 5. The second wristband 6 is fixedly connected to a first Velcro 8 at one end away from the fixing ring 5, and the third wristband 7 is fixedly connected to a second Velcro 9 at the other end away from the fixing ring 5. The first Velcro 8 and the second Velcro 9 are attached together. The first wristband 1 extends between the first Velcro 8 and the second Velcro 9 at one end away from the fixing ring 5, so that the first wristband 1 is attached to the second wristband 6 and the third wristband 7.

[0034] A connecting tube 12 is also connected to the fixing ring 5. One end of the connecting tube 12 passes through the fixing ring 5 and the main board 10 and extends into the airbag 4 to communicate with the airbag 4. The other end of the connecting tube 12 is connected to the connector 2.

[0035] like Figure 1 , Figure 3 As shown, three sliding grooves 11 are provided at intervals along the circumference of the outer peripheral wall of the fixing ring 5. The sliding grooves 11 extend along the circumference of the fixing ring 5. A connecting block 3 is slidably connected in each sliding groove 11. Each connecting block 3 is partially located inside the sliding groove 11 and the remaining part extends out of the sliding groove 11. The connecting block 3 located inside the sliding groove 11 can only slide in its corresponding sliding groove 11 along the circumference of the fixing ring 5 and cannot move radially along the fixing ring 5. A connecting block 3 is attached to the end of the first wristband 1, the second wristband 6, and the third wristband 7 near the fixing ring 5. The sliding angle of the first wristband 1, the second wristband 6, and the third wristband 7 along the fixing ring 5 is 30°.

[0036] like Figure 2 , Figure 4 As shown, the motherboard 10 has a groove 13 on the side closest to the user's skin, and the airbag 4 is set on the side wall of the motherboard 10 where the groove 13 is not set. The airbag 4 is set in a corresponding manner to the groove 13. The airbag 4 has an indicator ring 41. Both the airbag 4 and the motherboard 10 are made of transparent material, and both the airbag 4 and the motherboard 10 are made of lightweight and soft material.

[0037] The second wristband 6 includes a narrow section and a wide section that are integrally connected, and the third wristband 7 also includes a narrow section and a wide section that are integrally connected. The narrow section of the second wristband 6 is connected to the connecting block 3, and the wide section is provided with a first Velcro closure 8. The narrow section of the third wristband 7 is connected to the connecting block 3, and the wide section is provided with a second Velcro closure 9. Both the second wristband 6 and the third wristband 7 adopt a design that is narrower at the beginning and wider at the end. During wear, the wider part of the second wristband 6 and the third wristband 7 has a larger force-bearing area, which can disperse the force and reduce discomfort. The width of the first wristband 1 is smaller than the width of the narrow section of the second wristband 6 and also smaller than the width of the narrow section of the third wristband 7. The width of the first wristband 1 is 10-13mm. The first wristband 1 can easily wrap around the user's thumb and forefinger area and will not make deep contact with the base of the thumb and forefinger, causing the first wristband 1 to sink into the flesh and cause discomfort.

[0038] The outer diameter of the fixation ring 5 is 40-50mm. The fixation ring 5 is designed to be 3 / 5 the size of a normal adult's palm. The overall product is small, which can reduce the discomfort caused to the patient.

[0039] The working principle of the distal radial artery balloon hemostat provided by this utility model is as follows: Figure 5 As shown, after distal radial artery puncture, the fixing ring 5 is placed over the puncture point, and the indicator ring 41 of the airbag 4 corresponds to the puncture point. Both the airbag 4 and the main board 10 are transparent, which facilitates the placement of the indicator ring 41 and the puncture point. Then, the first wristband 1 is placed between the user's thumb and index finger and onto the back of the user's hand. The second wristband 6 and the third wristband 7 are then wrapped around the back of the user's hand. The first Velcro 8 and the second Velcro 9 are placed on the back of the user's hand. The positions of the first Velcro 8 and the second Velcro 9 are adjusted, and the end of the first wristband 1 away from the fixing ring 5 is placed on the first Velcro 8 and the second Velcro 9. The first Velcro 8 and the second Velcro 9 are then glued together, so that the first wristband 1, the second wristband 6, and the third wristband 7 are connected together through the first Velcro 8 and the second Velcro 9, so that the fixing ring 5 is firmly connected to the user. Then, the existing inflation device is connected to the connector 2 to inflate the airbag 4. The airbag 4 compresses the main board 10, thereby compressing the user's puncture point to achieve hemostasis.

[0040] Compared to existing technologies, this invention features a first, second, and third wristband that are slidably connected to the main board. When applying pressure for hemostasis to patients of different ages and hand shapes, the positions of the first, second, and third wristbands on the main board are adjusted to precisely control the three wristbands according to the patient's hand shape. This ensures the three wristbands fit snugly against the patient's hand, firmly fixing the main board to the patient's hand. This guarantees that the position of the airbag corresponds to the puncture point and prevents the airbag from shifting relative to the puncture point, ensuring the stability of the airbag position and firmly pressing the puncture point for hemostasis. Furthermore, this invention is simple to operate and saves time. Designed specifically for the shape of the thumb and forefinger, the first wristband is wide enough to easily wrap around the user's thumb and forefinger area, preventing deep contact and embedding of the wristband into the flesh, thus minimizing discomfort. The second and third wristbands are designed to widen gradually from narrow, providing a larger surface area for force distribution and reducing discomfort. The fixing ring is 3 / 5 the size of a normal adult hand, resulting in a compact overall product that minimizes discomfort for the patient. Both the airbag and mainboard are made of transparent material, with an indicator ring in the center of the airbag for easy observation of the puncture point, ensuring precise pressure application. Furthermore, both the airbag and mainboard are made of lightweight, soft materials to further reduce patient discomfort. Each wristband is slidably connected to the main board via a connecting block, and each wristband is fixed to the connecting block using adhesive. The second wristband has a first Velcro strap, and the third wristband has a second Velcro strap. To secure the first, second, and third wristbands, simply insert the first wristband between the first and second Velcro straps. The position and angle of each wristband can then be adjusted using the connecting blocks. The structure is simple, eliminating the need for binding the wristbands to the main board, and is convenient for patients to wear. An observation window is cut out on the main board. As the airbag inflates, it compresses the main board, providing downward pressure feedback to the compression point, thus increasing the pressure exerted by the airbag at that point.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
