Description

Technical Field

[0001] This utility model relates to the field of hemostasis mechanism technology, and in particular to a cardiology pressure hemostasis mechanism. Background Technology

[0002] Radial artery puncture is generally used for monitoring vital signs during surgical anesthesia and is an invasive arterial blood pressure monitoring procedure. After the sheath is removed, in order to avoid bleeding at the puncture site, pressure needs to be applied to the radial side before the sheath is removed. Existing hemostats need to be replaced after the pressure is applied. During the replacement process, the used hemostat needs to be removed and a new hemostat needs to be installed, which is a rather complicated operation.

[0003] In addition, existing hemostatic devices do not have a cooling effect and cannot relieve pain at the puncture site. Therefore, a cardiology-specific pressure hemostatic device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a cardiology pressure hemostasis mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cardiology compression hemostasis mechanism includes a wearable block and an assembly block. The wearable block has an air storage groove at its bottom and an air inlet at its top communicating with the air storage groove. An elastic membrane is fixedly connected to the opening of the air storage groove. The wearable block has a main storage groove and a secondary storage groove arranged opposite each other on its side wall. A main mounting block and a secondary mounting block are respectively provided at the openings of the main storage groove and the secondary storage groove. The bottom of the main storage groove and the secondary storage groove have openings. A winding rod and a unwinding rod are rotatably arranged at the center of the secondary mounting block. A tourniquet is wound around the unwinding rod. One end of the tourniquet is attached to the unwinding rod, and the other end of the tourniquet passes through the opening and is attached to the winding rod. An assembly block is arranged above the wearable block. A circular opening is provided at the center of the assembly block, and a piston assembly is arranged at the circular opening.

[0007] Preferably, a hanging ring is fixedly connected to the side wall of the wearable block, and a fixing strap is fixedly connected to the bottom of the wearable block. The surface of the fixing strap is provided with Velcro, and the fixing strap passes through the hanging ring and is attached to itself by Velcro.

[0008] Preferably, a rubber layer is provided at the connection between the unwinding rod and the auxiliary mounting block.

[0009] Preferably, the sidewall of the wearable block has insertion holes distributed around the circumference of the main storage slot and the secondary storage slot, and the sidewalls of the main mounting block and the secondary mounting block are fixedly connected with pins that are inserted into the insertion holes.

[0010] Preferably, a timer for timing is installed on the side wall of the wearable block.

[0011] Preferably, the top of the wearable block is fixedly connected to a fixing screw at one of the four corners, and the assembly block has an opening inside that is aligned with the fixing screw. The fixing screw passes through the opening and is threaded to a threaded cap at one end.

[0012] Preferably, the top of the wearable block is provided with a sealing groove, and the bottom of the assembly block is fixedly connected with a sealing ring that is inserted into the sealing groove.

[0013] Preferably, the piston assembly includes an air cylinder fixedly connected to the inner wall of a circular opening, a piston block slidably disposed inside the air cylinder, and a screw shaft rotatably disposed at the top of the piston block, the screw shaft being threadedly connected to the top of the air cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This solution is equipped with a winding rod, an unwinding rod, and a tourniquet. When the tourniquet needs to be replaced, the winding rod is turned to wind the tourniquet, and the used tourniquet is attached to the winding rod. At the same time, the unwinding rod unwinds the tourniquet, allowing the new tourniquet to move to the position below the elastic membrane, thus realizing the tourniquet replacement function. This eliminates the need for disassembly and installation of the tourniquet, providing convenience for tourniquet replacement.

[0016] 2. This solution is equipped with an air reservoir and a piston assembly. By turning the knob screw shaft, the piston block moves down and squeezes the gas inside the air cylinder into the air reservoir, causing the elastic membrane to expand and compress the tourniquet, thus achieving the compression function at the puncture point. By adjusting the position of the piston block, the amount of gas inside the air reservoir can be controlled, thereby controlling the degree of inflation of the airbag and thus controlling the compression force.

[0017] 3. This solution uses ice packs or other cooling substances placed inside the gas storage tank to provide a cooling effect on the puncture site during compression, thereby relieving pain at the puncture site. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 A cardiology compression hemostasis mechanism includes a wearable block 1 and an assembly block 2. The bottom end of the wearable block 1 is provided with an air storage groove 105, and the top end of the wearable block 1 is provided with an air inlet communicating with the air storage groove 105. An elastic membrane 14 is fixedly connected to the opening of the air storage groove 105. The assembly block 2 is provided above the wearable block 1. A circular opening is provided at the center of the assembly block 2. A piston assembly is provided at the circular opening. Further, the piston assembly includes an air cylinder 3 fixedly connected to the inner wall of the circular opening. A piston block 8 is slidably provided inside the air cylinder 3. A screw shaft 13 is rotatably provided at the top end of the piston block 8. The screw shaft 13 is threadedly connected to the top end of the air cylinder 3.

[0025] It should be noted that by rotating the screw shaft 13, the piston block 8 is driven to move down inside the air cylinder 3, pushing the gas inside the air cylinder 3 into the air storage tank 105, thereby causing the elastic membrane 14 to expand and squeeze the tourniquet 10, so that the tourniquet 10 can achieve the compression function of the puncture point.

[0026] By controlling the downward movement of the piston block 8 inside the air cylinder 3, the amount of gas inside the air storage tank 105 is controlled, thereby controlling the degree of expansion of the elastic membrane 14 and thus controlling the magnitude of the compressive force.

[0027] It should be noted that by placing ice packs or other cooling substances inside the air storage tank 105, the ice packs or other cooling substances can exchange heat with the elastic membrane 14 and the tourniquet 10 to achieve a cooling effect. In turn, the elastic membrane 14 and the tourniquet exchange heat with the puncture point to achieve a cooling effect on the puncture point and relieve the pain at the puncture point.

[0028] The wearable block 1 has a main storage slot 102 and a secondary storage slot 103 arranged opposite to each other on its side wall. A main mounting block 5 and a secondary mounting block 7 are respectively provided at the opening of the main storage slot 102 and the secondary storage slot 103. The bottom ends of the main storage slot 102 and the secondary storage slot 103 are provided with openings. A winding rod (with a knob at one end) is rotatably provided at the center of the secondary mounting block 7. Furthermore, a rubber layer is provided at the connection between the unwinding rod and the secondary mounting block 7 (the rubber layer can increase the rotational resistance of the unwinding rod, making it easier to keep the tourniquet 10 in a taut state). A unwinding rod is rotatably provided at the center of the secondary mounting block 7. The tourniquet 10 is wound on the unwinding rod. One end of the tourniquet 10 is attached to the unwinding rod, and the other end of the tourniquet 10 passes through the opening and is attached to the winding rod.

[0029] It should be noted that by rotating the winding rod, the used tourniquet 10 can be wound up, allowing the new tourniquet 10 to move to the position below the elastic membrane 14, thus enabling the tourniquet 10 to be replaced without the need for disassembly and installation of the tourniquet 10, providing convenience for the replacement of the tourniquet 10.

[0030] It is worth noting that when all the tourniquet 10 wrapped on the unwinding rod is unwound, the winding rod will wind up the tourniquet 10 when it rotates. Since one end of the tourniquet 10 is attached to the surface of the unwinding rod, the winding force of the winding rod can separate the adhesive joint between the tourniquet 10 and the surface of the unwinding rod, making it easier for the winding rod to fully recycle the tourniquet 10 after use.

[0031] Furthermore, a hanging ring is fixedly connected to the side wall of the wearable block 1, and a fixing strap 9 is fixedly connected to the bottom of the wearable block 1. The surface of the fixing strap 9 is provided with Velcro, and the fixing strap 9 passes through the hanging ring and is attached to itself by Velcro.

[0032] It should be noted that the wearing block 1 can be bound to the puncture point on the patient's arm using the fixing strap 9.

[0033] Furthermore, the side wall of the wearable block 1 is provided with insertion holes 104 distributed around the circumference of the main storage slot 102 and the secondary storage slot 103, and the side walls of the main mounting block 5 and the secondary mounting block 7 are fixedly connected with pins 12 that are inserted into the insertion holes 104.

[0034] It should be noted that the pin 12, in conjunction with the socket 104, can limit the movement of the main mounting block 5 and the secondary mounting block 7.

[0035] Furthermore, a timer 6 for timing is installed on the side wall of the wearable block 1. The timer 6 can serve as a timer and remind the patient to avoid prolonged pressure.

[0036] Furthermore, the top of the wearable block 1 is fixedly connected to the four corners with fixing screws 11, and the inside of the assembly block 2 is provided with a through hole aligned with the fixing screws 11. The fixing screw 11 passes through the through hole and is threadedly connected to a threaded cap 4.

[0037] It should be noted that the threaded cap 4, in conjunction with the fixing screw 11, enables the connection and assembly of the assembly block 2 and the wearable block 1.

[0038] Furthermore, a sealing groove 101 is provided at the top of the wearable block 1, and a sealing ring inserted into the sealing groove 101 is fixedly connected to the bottom of the assembly block 2.

[0039] It should be noted that the sealing ring, in conjunction with the sealing groove 101, can enhance the sealing performance at the connection between the assembly block 2 and the wearable block 1, thereby preventing air leakage from the air storage groove 105.

[0040] When this utility model is used, an ice pack or other cooling substance is placed inside the gas storage tank 105, and then the fixing screw 11 is passed through the opening. Then the threaded cap 4 is threadedly connected to the top of the fixing screw 11 to realize the connection and assembly function of the assembly block 2 and the wearable block 1.

[0041] Then, place the wearing block 1 at the puncture point, so that the tourniquet 10 fits the puncture point, then let the fixing strap 9 go around the arm, and let one end of the fixing strap 9 pass through the hanging loop, and let the fixing strap 9 pass through the hanging loop and be attached to itself by Velcro, so as to realize the function of binding the wearing block 1 at the puncture point.

[0042] Then rotate the screw shaft 13 so that the piston block 8 moves down along the air cylinder 3, squeezing the air cylinder 3 inside the air cylinder 3 into the air storage tank 105, causing the elastic membrane 14 to expand and squeeze the tourniquet 10, so that the tourniquet 10 can achieve the function of compressing the puncture point.

[0043] During the compression process, cooling substances such as ice packs can exchange heat with the elastic membrane 14 and tourniquet 10 to achieve a cooling effect. This allows the elastic membrane 14 and tourniquet to exchange heat with the puncture point, achieving a cooling effect on the puncture point and relieving pain at the puncture point.

[0044] When the compression operation is completed and the tourniquet 10 needs to be replaced, the winding rod can be rotated by turning the knob. The winding rod can wind up the used tourniquet 10, and at the same time the unwinding rod unwinds it, so that the new tourniquet 10 moves to the position below the elastic membrane 14, thus realizing the tourniquet 10 replacement function. This eliminates the need for disassembly and installation of the tourniquet 10, providing convenience for the replacement of the tourniquet 10.

[0045] When it is necessary to remove the used tourniquet 10 from the winding bar, remove the main mounting block 5 (so that the pin 12 is separated from the socket), and pull it out from the inside of the main storage slot 102. The used tourniquet 10 can then be removed directly from the winding bar.

[0046] When it is necessary to add a new tourniquet 10 to the unwinding rod, remove the auxiliary mounting block 7 (to separate the pin 12 from the socket) and pull it out from the inside of the auxiliary storage groove 103. One end of the new tourniquet 10 can be pasted onto the surface of the unwinding rod. Then, rotate the unwinding rod to realize the function of rewinding the new tourniquet 10. Then, place the unwinding rod with the new tourniquet 10 back into the auxiliary storage groove 103. Then, pull out one end of the new tourniquet 10 through the opening and extend it into the main storage groove 102. Place the rewinding rod into the main storage groove 102 and make the rewinding rod work with the inner wall of the main storage groove 102 to press one end of the new tourniquet 10 against the surface of the rewinding rod (double-sided tape can be applied to the surface of the rewinding rod in advance, and the length of the rewinding rod should be greater than the width of the tourniquet 10). Then, insert the pin 12 into the socket to complete the installation of the main mounting block 5, thus realizing the function of adding the new tourniquet 10.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
