Description
Technical Field
[0001] The present invention belongs to the technical field of compression hemostasis, and specifically refers to a compression hemostasis device. Background Art
[0002] A compression hemostasis device is a medical device that achieves hemostasis by applying mechanical pressure. It is widely used in vascular intervention surgeries, trauma first aid, and other scenarios that require rapid hemostasis. By applying compressive force to blood vessels or puncture sites, it promotes blood vessel closure or reduces blood leakage, thereby achieving hemostasis.
[0003] Currently, some compression hemostasis devices use direct compression. Prolonged use can lead to ischemia of the distal limb, causing serious consequences such as tissue necrosis and nerve damage. During use, it is difficult to apply uniform compression according to the shape of the wound and the contour of the limb, resulting in excessive local pressure and causing tissue damage.
[0004] Therefore, a compression hemostasis device is needed to solve the technical problems in the prior art that prolonged use can cause tissue necrosis, nerve damage, and it is difficult to apply uniform compression according to the shape of the wound and the contour of the limb, resulting in excessive local pressure. Summary of the Invention
[0005] In view of the above situation, to overcome the defects of the prior art, the present invention provides a compression hemostasis device. This application uses high-pressure air flow to expand the airbag ring and bind it to the limb to achieve rapid hemostasis. The high-pressure air can also drive the contact head to press annularly around the wound. While pressing, it can conform to the shape of the patient's limb to avoid excessive local pressure, solving the technical problem in the prior art that it is difficult to apply uniform compression according to the shape of the wound and the contour of the limb, resulting in excessive local pressure. The high-pressure air flow can also drive the contact head that presses annularly around the wound to stop pressing sequentially, solving the technical problem in the prior art that prolonged use can cause tissue necrosis and nerve damage. When the pressing stops, the high-pressure air flow blows towards the wound through the guide to cool the wound.
[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A compression hemostasis device proposed in this solution includes a connection seat. A bracelet is fixedly connected to the side wall of the connection seat. An airbag ring is fixedly connected to the inner circumferential wall of the bracelet. A pneumatic telescopic rod is fixedly connected to the connection seat. The output end of the pneumatic telescopic rod is fixedly connected to a moving box. The moving box is hollow. A pneumatic box is coaxially and fixedly connected to the inner top wall of the moving box. The inner bottom wall of the moving box is fixedly connected with fixed cylinders distributed in an annular array. The fixed cylinders communicate with the pneumatic box through the hollow part of the moving box.
[0007] Preferably, a moving groove and a guiding groove are provided inside the fixed cylinder. The moving groove is located above the guiding groove and is communicated with the guiding groove. A first magnet is longitudinally slidably connected inside the moving groove. A communication hole is connected to the top wall of the fixed cylinder. A guiding hole is communicated with the first magnet. The communication hole and the guiding hole are eccentrically arranged. An exhaust hole is communicated with the side wall of the moving groove.
[0008] Preferably, a pushing seat is longitudinally slidably connected inside the guiding groove. One end of the pushing seat slidably extends out of the moving box. A contact head is hinged to the extending end of the pushing seat.
[0009] Preferably, an annular air pipe is coaxially arranged inside the moving box. All the fixed cylinders are arranged around the annular air pipe and are fixedly connected to the outer wall of the annular air pipe. The moving groove is communicated with the annular air pipe through the exhaust hole. A communication pipe is fixedly communicated with the bottom wall of the annular air pipe. The other end of the communication pipe extends out of the moving box.
[0010] Preferably, an impeller is rotatably connected inside the pneumatic box. A rotating plate is rotatably connected to the bottom wall of the pneumatic box. One end of the rotating plate is coaxially fixedly connected to the impeller. The other end of the rotating plate is fixedly connected to a second magnet.
[0011] Preferably, a pressure sensor is fixedly connected to the bottom wall of the moving box. A hemostatic patch is pasted on the bottom wall of the moving box. The hemostatic patch covers the pressure sensor.
[0012] Preferably, an air valve is fixedly connected to the top wall of the connecting seat. The airbag ring, the pneumatic telescopic rod and the pneumatic box are respectively communicated with the air valve through air pipes. The pressure sensor is electrically connected to the air valve.
[0013] The beneficial effects achieved by the present invention with the above structure are as follows: 1. This application uses high-pressure air flow to expand the airbag ring and bind it to the limb to achieve rapid hemostasis. The high-pressure air can also drive the contact head to press annularly around the wound. While pressing, it can also conform to the shape of the patient's limb to avoid excessive local pressure. The high-pressure air flow can also drive the contact head pressing annularly around the wound to stop pressing sequentially. When the pressing stops, the high-pressure air flow blows through the guide to the periphery of the wound to cool the wound; 2. The high-pressure air flow drives the pushing seat and the contact head to approach the limb. The contact head contacts the limb skin and presses annularly around the wound. The contact head swings on the pushing seat, making the contact head conform to the shape of the limb. While pressing, it conforms to the shape of the patient's limb to avoid excessive local pressure; 3. The high-pressure air will also drive the impeller to rotate, driving the second magnet to magnetically attract the first magnet inside the fixed cylinder arranged in a ring shape. When the high-pressure air stops driving the pushing seat to approach the limb, the contact head pressing annularly around the wound stops pressing sequentially. The skin elasticity drives the contact head and the pushing seat to approach the inner top wall of the fixed cylinder, stopping pressing the skin; 4. When the pressure is stopped, the high-pressure air flow enters the annular trachea and the connecting pipe through the exhaust hole, and blows around the wound, reducing the local temperature and accelerating blood coagulation, while reducing the accumulation of exudate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.
[0019] Embodiment 1, as Figures 1 - 5As shown in the figure, a compression hemostasis device proposed by this solution includes a connecting seat 3. A bracelet 1 is fixedly connected to the side wall of the connecting seat 3. An airbag ring 2 is fixedly connected to the inner circumferential wall of the bracelet 1. A pneumatic telescopic rod 4 is fixedly connected to the connecting seat 3. The output end of the pneumatic telescopic rod 4 is fixedly connected to a moving box 5. The moving box 5 is hollow. A pneumatic box 7 is coaxially fixedly connected to the inner top wall of the moving box 5. The inner bottom wall of the moving box 5 is fixedly connected with fixing cylinders 6 distributed in an annular array. The fixing cylinders 6 communicate with the pneumatic box 7 through the hollow part of the moving box 5.
[0020] As Figures 1 - 3 shown, a moving groove 61 and a guiding groove 67 are provided in the fixing cylinder 6. The moving groove 61 is located above the guiding groove 67 and the moving groove 61 communicates with the guiding groove 67. A first magnet 62 is longitudinally slidably connected in the moving groove 61. A communication hole 611 is connected to the top wall of the fixing cylinder 6. A guiding hole 612 communicates with the first magnet 62. The communication hole 611 and the guiding hole 612 are eccentrically arranged. An exhaust hole 613 communicates with the side wall of the moving groove 61. When the top wall of the first magnet 62 contacts the top wall of the moving groove 61, the communication hole 611 and the guiding hole 612 are blocked, and the guiding groove 67 communicates with the exhaust hole 613. When the bottom wall of the first magnet 62 contacts the bottom wall of the moving groove 61, the first magnet 62 blocks the exhaust hole 613, and the guiding hole 612 communicates with the communication hole 611.
[0021] As Figures 1 - 3 shown, a pushing seat 65 is longitudinally slidably connected in the guiding groove 67. One end of the pushing seat 65 slides out of the moving box 5. A contact head 66 is hinged to the protruding end of the pushing seat 65.
[0022] As Figures 1 - 3 and Figure 5 shown, an annular air pipe 63 is coaxially arranged in the moving box 5. All the fixing cylinders 6 are arranged around the annular air pipe 63 and fixedly connected to the outer wall of the annular air pipe 63. The moving groove 61 communicates with the annular air pipe 63 through the exhaust hole 613. A communicating pipe 64 is fixedly connected to the bottom wall of the annular air pipe 63. The other end of the communicating pipe 64 extends out of the moving box 5.
[0023] As Figures 1 - 2 and Figures 4 - 5 shown, an impeller 71 is rotatably connected in the pneumatic box 7. A rotating plate 72 is rotatably connected to the bottom wall of the pneumatic box 7. One end of the rotating plate 72 is coaxially fixedly connected to the impeller 71. The other end of the rotating plate 72 is fixedly connected to a second magnet 73. The fixing cylinders 6 are evenly distributed in an annular array below the second magnet 73. When the second magnet 73 and the first magnet 62 are coaxially arranged, the second magnet 73 magnetically attracts the first magnet 62.
[0024] As Figures 1 - 2As shown, a pressure sensor 52 is fixedly connected to the bottom wall of the moving box 5, and a hemostatic patch 51 is adhered to the bottom wall of the moving box 5. The hemostatic patch 51 covers the pressure sensor 52.
[0025] As Figures 1 - 2 shown, an air valve 53 is fixedly connected to the top wall of the connecting seat 3. The airbag ring 2, the pneumatic telescopic rod 4, and the pneumatic box 7 are respectively communicated with the air valve 53 through air pipes. The pressure sensor 52 is electrically connected to the air valve 53.
[0026] Put the bracelet 1 and the airbag ring 2 on the patient's limb. The hemostatic patch 51 is aligned with the wound position. The air valve 53 is connected to an external air source. High-pressure air flows through the air valve 53 into the airbag ring 2. The airbag ring 2 expands, and the expanded airbag ring 2 drives the bracelet 1 to bind to the limb. Then, the high-pressure air flows through the air valve 53 into the pneumatic telescopic rod 4. The pneumatic telescopic rod 4 drives the moving box 5 and the hemostatic patch 51 to approach the wound. The hemostatic patch 51 contacts the wound and presses the pressure sensor 52. When the pressure sensor 52 detects that the hemostatic patch 51 presses the wound, the pneumatic telescopic rod 4 stops; When the pneumatic telescopic rod 4 stops, the high-pressure air flows through the air valve 53 into the pneumatic box 7. The high-pressure air pushes the impeller 71 to rotate and is discharged into the moving box 5 at the same time. The high-pressure air flows through the communication hole 611 on the fixed cylinder 6 into the moving groove 61. The high-pressure air presses the first magnet 62 against the bottom wall of the moving groove 61. The first magnet 62 blocks the exhaust hole 613. The high-pressure air flows through the guiding hole 612 on the first magnet 62 into the guiding groove 67. The high-pressure air drives the pushing seat 65 to approach the limb. The pushing seat 65 drives the contact head 66 to approach the limb. The contact head 66 contacts the limb skin and annularly presses around the wound. At the same time, the contact head 66 also swings on the pushing seat 65, so that the contact head 66 fits the shape of the limb. The annular contact head 66 evenly presses around the wound while fitting the shape of the patient's limb, avoiding excessive local pressure; When the high-pressure air drives the impeller 71 to rotate, the impeller 71 drives the rotating plate 72 to rotate, the rotating plate 72 drives the second magnet 73 to rotate. When the second magnet 73 is coaxially arranged with one of the fixed cylinders 6 in the annular array, the second magnet 73 magnetically attracts the first magnet 62, and the first magnet 62 contacts the top wall of the moving groove 61, blocking the communication hole 611 and the guiding hole 612. The air in the moving box 5 stops entering the guiding groove 67. The first magnet 62 moves away from the exhaust hole 613, and the high-pressure air flow in the guiding groove 67 enters the annular air pipe 63. The skin elasticity drives the contact head 66 and the pushing seat 65 to approach the inner top wall of the fixed cylinder 6, stopping pressing the skin. The high-pressure air flow passes through the pushing seat 65 and flows to the communication pipe 64, blowing towards the wound periphery to cool the wound. As the impeller 71 continues to rotate, the second magnet 73 moves away from the first magnet 62, and the high-pressure air flow enters the moving groove 61 through the communication hole 611 on the fixed cylinder 6. The contact head 66 contacts the limb skin and presses again. As the impeller 71 continues to rotate, the contact heads 66 pressing circularly around the wound stop pressing in sequence, avoiding problems such as local ischemia, nerve damage, skin necrosis or thrombosis caused by long-term compression. When it is necessary to remove it, the air valve 53 is disconnected from the external air source, and then the high-pressure air flow in the airbag ring 2 is discharged through the air valve 53. At the same time, the pneumatic telescopic rod 4 resets, and the pneumatic telescopic rod 4 drives the moving box 5 away from the limb. The hemostatic piece 51 moves away from the wound, and the contact head 66 moves away from the skin, stopping pressing around the wound. Then the bracelet 1 and the airbag ring 2 are removed from the limb.
[0027] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the purpose of the present invention creation, without creative design, they design similar structural manners and embodiments to this technical solution, which should all fall within the protection scope of the present invention.
