Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a brachial artery compression hemostat. Background Art

[0002] Minimally invasive interventional surgeries in vascular surgery and neurosurgery are used to treat complex diseases such as aortic dissection, carotid artery stenosis and occlusion, and lower limb artery stenosis and occlusion, especially those with vascular anatomical variations. Brachial artery puncture is a surgical approach. Currently, there is no dedicated arm fixation and compression hemostat for brachial artery puncture. Patients often experience involuntary arm bending after brachial artery puncture, which increases bleeding and subcutaneous congestion at the puncture site, as well as postoperative complications such as brachial artery pseudoaneurysm. Arm immobilization restricts patient activity, greatly prolongs bed rest and upper limb immobilization time after intervention, and increases the risk of postoperative deep vein thrombosis. Currently, most patients undergoing this type of surgery are elderly patients who take anticoagulants and antiplatelet drugs for a long time. This increases the risk of bleeding, so a brachial artery puncture site hemostatic fixator is urgently needed.

[0003] Currently, there are only compression hemostats on the market for the femoral and radial arteries. However, these devices cannot be used on the brachial artery because the elbow joint of the upper limb is relatively mobile, and the size and fixation of these devices are not suitable for the elbow joint. Currently, elastic bandages are the only available method for hemostasis, which has various drawbacks. The main clinical manifestations are as follows:

[0004] 1. The pressure applied by elastic bandages varies. If the pressure is too tight, it will cause ischemia of the upper limbs, even ischemic necrosis of the fingertips, venous return obstruction and swelling of the upper limbs; if the pressure is too loose, it will not be able to effectively stop bleeding, leading to upper limb hematoma, massive bleeding, even brachial artery pseudoaneurysm, hemorrhagic shock, etc.

[0005] 2. Some patients are allergic to the elastic bandage materials and develop allergic symptoms such as skin blisters after 24 hours of compression.

[0006] 3. Most patients who undergo brachial artery puncture surgery require anticoagulant or antiplatelet therapy. Elastic bandages cannot restrict upper limb movement. Many patients experience involuntary upper limb movement after surgery, resulting in ineffective compression hemostasis and delayed bleeding at the puncture site, leading to the occurrence of pseudoaneurysm.

The base 100 is provided with a first through hole 110 in a first direction, and the base 100 is provided with a second through hole 120 in a second direction perpendicular to the first direction. The first end of the first tourniquet 200 is connected to the base 100, and the second end of the first tourniquet 200 is plugged into and fitted with the first through hole 110. The first end of the second tourniquet 300 is connected to the base 100, and the second end of the second tourniquet 300 is plugged into and fitted with the second through hole 120. The fixing structure 400 is used to fix the second end of the first tourniquet 200 and the second end of the second tourniquet 300.

[0061] The brachial artery compression hemostat disclosed in this embodiment has a simple structure and is easy to use. It uses two tourniquets for cross-binding, which can effectively fix the patient's upper limbs, thereby reducing the occurrence of thrombus shedding at the brachial artery puncture site due to upper limb movement.

[0062] In some embodiments of this embodiment, the fixing structure 400 includes a first fixing block 410 and a second fixing block 420. The first fixing block 410 and the second fixing block 420 are both installed on the base body 100, and the first fixing block 410 is set toward the first through hole 110, and the second fixing block 420 is set toward the second through hole 120. When the first fixing block 410 enters the first through hole 110, the second end of the first tourniquet 200 is fixed, and when the second fixing block 420 enters the second through hole 120, the second end of the second tourniquet 300 is fixed.

[0063] Using the first fixing block 410 to fix the first tourniquet 200 and using the second fixing block 420 to fix the second tourniquet 300 can effectively fix the patient's upper limbs with the first tourniquet 200 and the second tourniquet 300, and the cross-arranged first tourniquet 200 and the second tourniquet 300 are fixed more conveniently and firmly.

[0064] In some embodiments of this embodiment, the fixed structure 400 also includes a control rod 440 and a control block 430. The control rod 440 is rotatably connected to the base body 100, and the control block 430 is connected to the control rod 440. The length of the control block 430 is greater than its width. The control block 430 is rotated to allow the first fixed block 410 to enter or leave the first through hole 110.

[0065] The control rod 440 and the control block 430 are used to control the position of the first fixing block 410 . On the one hand, it is easy to control the fixing position of the first tourniquet 200 to control the tightness. On the other hand, it is more convenient to disassemble and assemble the first tourniquet 200 .

[0066] In some implementations of this embodiment, the control block 430 is located between the first fixing block 410 and the second fixing block 420 , and the control block 430 is rotated to allow the second fixing block 420 to enter or leave the second through hole 120 .

[0067] The control rod 440 and the control block 430 are used to simultaneously control the first fixing block 410 and the second fixing block 420, making the structure more compact and simple, and the operation more convenient.

[0068] In some implementations of this embodiment, a first limiting portion 210 is provided at the second end of the first tourniquet 200 , and the first limiting portion 210 cooperates with the first fixing block 410 to fix the second end of the first tourniquet 200 ;

[0069] The second end of the second tourniquet 300 is provided with a second limiting portion 310 , and the second limiting portion 310 cooperates with the second fixing block 420 to fix the second end of the second tourniquet 300 .

[0070] The first limiting portion 210 and the second limiting portion 310 can be configured to be in a ratchet shape, so that when they cooperate with the first fixing block 410 and the second fixing block 420, a one-way control effect can be formed, that is, the first tourniquet 200 and the second tourniquet 300 can only move in one direction, thereby achieving a tightening and fixing effect.

[0071] In some implementations of this embodiment, the fixing structure 400 also includes a first spring member and a second spring member, the two ends of the first spring member are respectively connected to the first fixing block 410 and the base body 100, and the first spring member causes the first fixing block 410 to have a tendency to leave the first through hole 110, and the two ends of the second spring member are respectively connected to the second fixing block 420 and the base body 100, and the second spring member causes the second fixing block 420 to have a tendency to leave the second through hole 120.

[0072] The arrangement of the first spring member and the second spring member can ensure that when the control block 430 rotates, the bottoms of the first fixed block 410 and the second fixed block 420 are always attached to the control block 430, thereby ensuring that when the first fixed block 410 and the second fixed block 420 need to leave the first through hole 110 and the second through hole 120, the first fixed block 410 and the second fixed block 420 can leave quickly.

[0073] See Figure 8 and Figure 9 In some implementations of this embodiment, the first end of the first fixing block 410 is rotatably connected to the base body 100, the first spring member is connected to the second end of the first fixing block 410, the second spring member causes the second end of the first fixing block 410 to have a tendency to rotate toward the outside of the first through hole 110, and the rotation control block 430 causes the second end of the first fixing block 410 to enter or leave the first through hole 110. When the second end of the first fixing block 410 enters the first through hole 110, the second end of the first fixing block 410 cooperates with the first limiting portion 210 to fix the second end of the first tourniquet 200.

[0074] The first end of the second fixing block 420 is rotatably connected to the base body 100, and the second spring member is connected to the second end of the second fixing block 420. The second spring member causes the second end of the second fixing block 420 to have a tendency to rotate toward the outside of the second through hole 120. The rotation control block 430 allows the second end of the second fixing block 420 to enter or leave the second through hole 120. When the second end of the second fixing block 420 enters the second through hole 120, the second end of the second fixing block 420 cooperates with the second limiting portion 310 to fix the second end of the second tourniquet 300.

[0075] When the second end of the first fixing block 410 and the second end of the second fixing block 420 rotate to extend into the first through hole 110 and the second through hole 120, they can respectively cooperate with the first fixing portion and the second fixing portion to allow the first tourniquet 200 and the second tourniquet 300 to move only in one direction.

[0076] See Figures 4 to 7 In some implementations of this embodiment, a first limiting tooth is provided on a side of the first fixing block 410 facing the first through hole 110. When the first fixing block 410 enters the first through hole 110, the first limiting tooth cooperates with the first limiting portion 210 to fix the second end of the first tourniquet 200.

[0077] A second limiting tooth is provided on one side of the second fixing block 420 facing the second through hole 120 . When the second fixing block 420 enters the second through hole 120 , the second limiting tooth cooperates with the second limiting portion 310 to fix the second end of the second tourniquet 300 .

[0078] The first limiting tooth and the second limiting tooth can be designed to be a ratchet-like shape adapted to the shape of the first limiting portion 210 and the second limiting portion 310. When the first limiting tooth cooperates with the first limiting portion 210, it can ensure that the first tourniquet 200 can only move in one direction. When the second limiting tooth cooperates with the second limiting portion 310, it can ensure that the second tourniquet 300 can only move in one direction.

[0079] See 3 and Figure 10 In some implementations of this embodiment, the brachial artery compression hemostat disclosed in this embodiment also includes a positioning belt 500, and both ends of the positioning belt 500 are respectively connected to the seat body 100 to form mounting holes, and the positioning belt 500 is made of elastic material.

[0080] The design of the positioning band 500 can ensure that the brachial artery compression hemostat is installed more conveniently. The positioning band 500 can provide a preliminary position fixation for the base 100 when the first tourniquet 200 and the second tourniquet 300 are not fixed.

[0081] In some embodiments of this embodiment, a first positioning hole 510 and a second positioning hole 520 are provided on the positioning belt 500, and the first positioning hole 510 and the second positioning hole 520 are vertically arranged. The first tourniquet 200 is passed through the first positioning hole 510, and the second tourniquet 300 is passed through the second positioning hole 520.

[0082] Since the positioning band 500 can control a portion of the first tourniquet 200 and the second tourniquet 300 , the installation of the first tourniquet 200 and the second tourniquet 300 can be made more convenient.

[0083] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible.
