Description

Technical Field

[0001] This utility model relates to the field of hemostatic equipment technology, and in particular to an arterial hemostatic device. Background Technology

[0002] Arterial interventional surgery typically involves inserting a guidewire through an artery (such as the femoral, radial, brachial, or carotid artery) to the narrowed area, then using techniques such as rotation cutting, balloon dilation, and stenting to relieve the vascular stenosis and restore blood flow. After arterial interventional surgery, hemostasis at the puncture site is crucial. Effectively shortening the compression time, maintaining stable pressure on the puncture site, and minimizing bleeding and postoperative complications have always been key concerns for clinicians. Current techniques often employ bandages or hemostatic devices for hemostasis. Manual bandages require manual pressure, which is time-consuming, laborious, and ineffective. Existing hemostatic devices suffer from prolonged compression time, excessive bleeding during hemostasis, and adverse complications such as skin ulceration, hematoma, and arterial occlusion after hemostasis. Utility Model Content

[0003] The present invention aims to at least solve the technical problems of long compression time and poor hemostasis in the prior art.

[0004] Therefore, one objective of this utility model is to provide an arterial hemostat, which includes a pressure plate, a fixing component, a hemostatic component, and a coagulation-promoting layer. The pressure plate and the fixing component form a receiving space. The hemostatic component is installed on the pressure plate. The end of the hemostatic component facing the receiving space is provided with a coagulation-promoting layer. By adjusting the hemostatic component, the coagulation-promoting layer is brought closer to the patient's puncture site to compress and stop bleeding at the puncture site.

[0005] In some embodiments, the hemostatic assembly includes a drive member and an adjustment section connected in sequence, the drive member driving the adjustment section to move, and the coagulation-promoting layer being disposed at one end of the adjustment section facing the receiving space.

[0006] In some embodiments, the adjusting part includes a first screw, an adjusting nut, a spring, and a sleeve. One end of the first screw is fixedly connected to the driving member, and the other end of the first screw is sequentially provided with the spring and the adjusting nut. The adjusting nut is disposed inside the sleeve and can drive the sleeve to move. The coagulation layer is disposed in the sleeve.

[0007] In some embodiments, the pressure plate has a first mounting hole, the adjustment part includes a second screw and a fixing member, the second screw is threadedly connected to the wall of the first mounting hole, the fixing member is provided at one end of the second screw near the receiving space, and the coagulation layer is disposed on the fixing member.

[0008] In some embodiments, the fixing component includes a first fixing strap, the two ends of which respectively engage with the two ends of the pressure plate.

[0009] In some embodiments, the fastening component includes a buckle plate, one end of the pressure plate is fixedly connected to one end of the first fastening strap, the other end of the pressure plate is equipped with the buckle plate, the buckle plate has a buckle plate hole, and the other end of the first fastening strap passes through the buckle plate hole and can cooperate with the strap body of the first fastening strap.

[0010] In some embodiments, the fixation assembly includes a second fixation strap connected to the pressure plate, and the first and second fixation straps are used to fix different parts of the patient.

[0011] In some embodiments, the coagulation layer is a hydrogel coagulation layer, a chitosan coagulation layer, or a silver ion-containing dressing coagulation layer.

[0012] In some embodiments, the outer contour of the coagulation-promoting layer is circular, square, or conical.

[0013] In some embodiments, a pressure member is provided between the coagulation accelerator and the regulating part.

[0014] The arterial hemostat provided in this embodiment of the utility model has the following beneficial effects:

[0015] This solution uses a pressure plate to support the hemostasis component, a fixing component to fix the arterial hemostat to the patient, and the hemostasis component to apply pressure to the puncture site for hemostasis. During hemostasis, the hemostasis component is adjusted to bring the procoagulant layer closer to the patient's puncture site to apply pressure for hemostasis.

[0024] Various embodiments and features of this utility model are described herein with reference to the accompanying drawings.

[0025] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be considered as limiting, but merely as an example of embodiments. Other modifications within the scope and spirit of this invention will be apparent to those skilled in the art.

[0026] The accompanying drawings, which are included in and form part of this specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, serve to explain the principles of the present invention.

[0027] These and other features of the present invention will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0028] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of the present invention, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0029] The above and other aspects, features and advantages of the present invention will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0030] Specific embodiments of the present invention will now be described with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present invention, which may be implemented in various ways. Well-known and / or repeated functions and structures have not been described in detail to avoid unnecessary or redundant details that could obscure the present invention. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of substantially any suitable detailed structures.

[0031] An embodiment of this utility model provides an arterial hemostat, such as... Figures 1-5 As shown, this arterial hemostat can conveniently and quickly stop bleeding at arterial puncture sites, thereby reducing compression time and simplifying intraoperative hemostasis. It is suitable for hemostasis after punctures of arteries such as the carotid artery, brachial artery, and proximal radial artery. The arterial hemostat includes a pressure plate 1, a fixation component 2, a hemostatic component 3, and a coagulation-promoting layer 4. The pressure plate 1 and the fixation component 2 form a receiving space. The hemostatic component 3 is installed on the pressure plate 1. The end of the hemostatic component 3 facing the receiving space has a coagulation-promoting layer 4. The pressure plate 1 supports the hemostatic component 3, the fixation component 2 fixes the arterial hemostat to the patient, the hemostatic component 3 applies pressure to the puncture site for hemostasis, and the coagulation-promoting layer 4 accelerates the coagulation rate. Specifically, by adjusting the hemostatic component 3, the coagulation-promoting layer 4 is brought closer to the patient's puncture site to apply pressure for hemostasis.

[0032] The fixing component 2 includes a first fixing strap 21, the two ends of which respectively engage with the two ends of the pressure plate 1. For example, the pressure plate 1 has a second mounting hole 12 and a third mounting hole 13 on both sides, which engage with the two ends of the first fixing strap 21. Specifically, the fixing component 2 also includes a buckle plate 22. One end of the first fixing strap 21 is a fixed end 211, which is fixedly connected to one end of the pressure plate 1. The other end of the first fixing strap 21 is a movable end 212, which is installed on the buckle plate 22. The buckle plate 22 has a buckle hole. In use, the movable end 212 of the first fixing strap 21 passes through the buckle hole and engages with the strap body 213 of the first fixing strap 21. For example, the movable end 212 of the first fixing strap 21 is bonded to the strap body 213 of the first fixing strap 21. When performing hemostasis, the movable end 212 of the first fixing strap 21 needs to be tightened and attached to the strap body 213 of the first fixing strap 211. The size of the accommodating space 5 between the fixing component 2 and the pressure plate 1 can be adjusted by adjusting the length of the movable end 212 of the first fixing strap 21 through the buckle hole, thereby achieving a stable fit with the patient and fixing the arterial hemostat.

[0033] like Figure 2 As shown, the buckle plate 22 and the pressure plate 1 are either fixedly connected or detachably connected. A fixed connection between the buckle plate 22 and the pressure plate 1 increases the strength of the fixing component 2, while a detachable connection makes installation and removal of the buckle plate 22 and the pressure plate 1 more convenient and quick. The end of the buckle plate 22 that mates with the third mounting hole 13 has a claw 221, which enables a stable and quick connection between the buckle plate 22 and the pressure plate 1. For example, the claw 221 is U-shaped.

[0034] Furthermore, such as Figure 2 As shown, the pressure plate 1 has a support member 14 on its inner side. The inner side refers to the side facing the receiving space. The support member 14 can be set as a T-shaped silicone. When stopping bleeding, it can contact the patient's skin surface to play a role in anti-slip fixation.

[0035] The pressure plate 1 can be set as a rectangular plate structure, but in order to adapt to distal radial compression hemostasis, the pressure plate 1 can also be designed as a triangle.

[0036] In some embodiments, the fixation component 2 has only a first fixation strap 21, which is suitable for hemostasis after puncture of arteries such as the carotid artery, brachial artery and proximal radial artery.

[0037] In other embodiments, the fixing component 2, in addition to having a first fixing strap 21, also includes a second fixing strap 23, which is connected to the pressure plate 1, such as... Figure 3 and Figure 5 As shown, the first fixation strap 21 and the second fixation strap 23 are used to fix different parts. For example, when hemostasis is required at the distal radial puncture site, the second fixation strap 23 is a thumb strap to fix the thumb, which makes it easier to fix the arterial hemostat 1 at the distal radial puncture site; or, the first fixation strap 21 and the second fixation strap 23 can be a leg fixation strap and a waist fixation strap, respectively, and multiple fixation straps can be used to improve the fixation effect.

[0038] Furthermore, such as Figure 2 and Figure 4 As shown, the hemostatic assembly 3 includes a driving member 31 and an adjusting part 32 connected in sequence. The driving member 31 drives the adjusting part 32 to move, and the coagulation-promoting layer 4 is disposed at the end of the adjusting part 32 facing the receiving space 5. In use, the driving member 31 drives the adjusting part 32 to move towards the puncture site, pressing the coagulation-promoting layer 4 against the puncture site, thereby achieving rapid hemostasis.

[0039] Specifically, in some embodiments, such as Figures 1-3 As shown, the driving component 31 is an adjusting nut 311, and the adjusting part 32 includes a first screw 321, an adjusting nut 322, a spring 323, and a sleeve 324. One end of the first screw 321 is fixedly connected to the driving component 31, and the other end of the first screw 321 is provided with a spring 323 and an adjusting nut 322 in sequence. The adjusting nut 322 is disposed inside the sleeve 324 and can drive the sleeve 324 to move. The coagulation layer 4 is disposed in the sleeve 324. The pressure plate 1 has a pressure plate cylinder 15 on its outer side. The adjusting nut 322 is threadedly connected to the sleeve 324. One end of the first screw 321 passes through the pressure plate cylinder 15 and is fixed to the driving member 31. The other end of the first screw 321 passes through the spring 323 and is limited in the hole of the adjusting nut 322. When the arterial hemostat is fixed at the puncture site, the first screw 321 is rotated by rotating the driving member 31. At the same time, the first screw 321 rotates and the adjusting nut 322 rotates, causing the spring 323 to be compressed. The spring 323 is compressed and deformed to generate thrust, which is finally transmitted to the coagulation layer 4 through the sleeve 324, generating pressure on the patient's puncture site, thereby achieving a rapid hemostasis effect.

[0040] Furthermore, the coagulation layer 4 can be directly attached to the sleeve 324. The outer periphery of the adjusting nut 322 is provided with an annular part 325, and the outer periphery of the pressure plate cylinder 15 is longitudinally distributed with scales. The pressure force can be determined by reading the scale value corresponding to the annular part 325, or the required pressure force can be achieved by rotating the adjusting nut 322. The annular part 325 here can be an O-ring.

[0041] In other embodiments, the structure of the adjustment unit 32 described above differs from that of the other embodiments, such as... Figure 4As shown, the pressure plate 1 has a first mounting hole 11. The driving component 31 is an adjusting handle 312. The adjusting part 32 includes a second screw 326 and a fixing member 327. The second screw 326 is threadedly connected to the wall of the first mounting hole 11. The fixing member 327 is located at the end of the second screw 326 near the receiving space. The coagulation-promoting layer 4 is disposed on the fixing member 327. The second screw 326 has external threads that pass through the first mounting hole 11 on the pressure plate 1 and are threadedly connected. In use, the adjusting handle 312 can rotate to move the second screw 326 up and down, thereby moving the fixing member 327 connected to the second screw 326 closer to or away from the puncture site. When the fixing member 327 presses against the puncture site, a pressure-adding effect is achieved. The coagulation-promoting layer 4, disposed on the fixing member 327, promotes blood clotting during pressure application. The fixing member 327 can be configured as a boss protruding towards the puncture site. By setting the contact area between the fixing member 327 and the puncture site to be smaller, the pressure is greater when the fixing member 327 is pressed against the puncture site, thereby improving the hemostasis effect.

[0042] Among them, such as Figure 1 As shown, a pressing member 328 is provided between the accelerator layer 4 and the adjusting part 32. This pressing member 328 can be configured as a pressing silicone layer. Specifically, the pressing silicone layer is in contact with the sleeve 324 (or the fixing member 327) and provides a certain supporting function when pressure is applied. It should be noted that in some designs, the accelerator layer 4 can be made of a harder material, thus omitting the pressing silicone layer.

[0043] The coagulation-promoting layer 4 mentioned here is a hydrogel coagulation-promoting layer 4, a chitosan coagulation-promoting layer 4, or a silver ion-containing dressing coagulation-promoting layer 4. That is, the surface of the coagulation-promoting layer 412 has a layer of coagulation-promoting substance, which can be a hydrogel, chitosan, silver ion-containing dressing, etc., which can promote rapid coagulation of blood at the puncture site.

[0044] The coagulation-promoting layer 4 here has a variety of shapes, with its outer contour being circular, square, or conical, to adapt to different puncture sites and better fit the puncture point. The outer contour shape of the coagulation-promoting layer 4 can also be selected in other shapes according to requirements.
