Description

Technical Field

[0001] This invention relates to the field of tourniquet processing technology, and more particularly to a tourniquet processing device and a tourniquet. Background Technology

[0002] Tourniquets are made of medical-grade high-polymer materials, such as natural rubber or special rubber. They are long, flat, and highly elastic. They are suitable for single-use use in medical institutions for routine treatment and rescue procedures, including intravenous infusions, blood draws, and transfusions, to stop bleeding; or for emergency hemostasis of limb bleeding or bleeding from snake or insect bites in the wild.

[0003] Currently, tourniquets on the market tend to have limited color options and lack design patterns, making them less appealing to children. During treatment, children may require more verbal reassurance from parents or medical staff, potentially impacting treatment efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tourniquet processing device and tourniquet to solve the technical problems that the tourniquets on the market are relatively monochromatic and lack pattern design, which is not attractive to children; and that children may need more verbal reassurance from parents or medical staff during treatment, which affects the efficiency of treatment.

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

[0006] In a first aspect, the present invention provides a tourniquet processing apparatus, including a frame, and a first conveying assembly, a second conveying assembly, a transfer assembly, and a substrate assembly disposed on the frame. The first conveying assembly is used to convey transfer paper, and the second conveying assembly is used to convey a tourniquet. Both the transfer paper conveyed by the first conveying assembly and the tourniquet conveyed by the second conveying assembly pass between the transfer assembly and the substrate assembly. The transfer assembly and / or the substrate assembly are movable to press the transfer paper and the tourniquet together between the transfer assembly and the substrate assembly. The transfer assembly is used to heat the transfer paper to transfer the colored pattern of the transfer paper to the side where the tourniquet and the transfer paper are pressed together.

[0007] Furthermore, the first conveying assembly includes a first transfer roller and a second transfer roller rotatably disposed on the frame, the transfer paper being connected between the first transfer roller and the second transfer roller, the first transfer roller being used to feed the transfer paper out, and the second transfer roller being used to wind the transfer paper; the transfer assembly is located on the side of the transfer paper away from the tourniquet, and the transfer paper and the tourniquet are pressed together between the first transfer roller and the second transfer roller.

[0008] Furthermore, the second conveying assembly includes a mounting base disposed on the frame, and a first roller group and a second roller group disposed on the mounting base; the mounting base is provided with a first through hole, and the first roller group and the second roller group are respectively disposed on both radial sides of the first through hole, and the tourniquet passes through the first roller group, the first through hole and the second roller group in sequence;

[0009] The first roller group has a first gap for the tourniquet to pass through, and the first roller group is used to move the tourniquet passing through the first gap toward the second roller group; the second roller group has a second gap for the tourniquet to pass through, and the second roller group is used to move the tourniquet passing through the second gap away from the first roller group; the printing assembly is located on the side of the tourniquet away from the transfer paper, and the transfer paper and the tourniquet are pressed together at the first through hole.

[0010] Furthermore, the transfer component and the substrate component are respectively disposed on both sides of the first through hole, and the transfer component and the substrate component move along the axial direction of the first through hole to move closer to or further away from each other, and the moving intersection position of the transfer component and the substrate component is located inside the first through hole.

[0011] Furthermore, it also includes a flipping assembly, wherein the mounting base is rotatably connected to the frame, and the flipping assembly is used to drive the mounting base to flip, thereby causing the first roller group, the second roller group and the tourniquet located between the first roller group and the second roller group to flip; wherein the flipping assembly drives the mounting base to flip by a single angle of 180°.

[0012] Furthermore, the mounting base is provided with a first flip trigger button and a second flip trigger button on the surfaces of both sides along the axial direction of the first through hole; the transfer assembly includes a hot press plate that moves along the central axis of the first through hole, and a connecting plate disposed on the side of the hot press plate away from the mounting base; the printing assembly includes a printing plate that moves along the central axis of the first through hole.

[0013] When the hot press plate and the printing plate approach each other and extend into the first through hole to press the transfer paper and tourniquet therein, the connecting plate presses the first flip trigger button or the second flip trigger button; when the hot press plate and the printing plate move away from each other and disengage from the first through hole, the connecting plate releases the first flip trigger button or the second flip trigger button that it has pressed; when the first flip trigger button or the second flip trigger button experiences one press and release, the flipping assembly drives the mounting base to flip.

[0014] Furthermore, the movement path of the printing component is provided with a cleaning component. When the printing component moves away from the transfer component and passes the cleaning component, the cleaning component cleans the pressing surface of the printing component corresponding to the transfer component.

[0015] Furthermore, the cleaning component includes a trigger, a rebound member, and a cleaning member. The trigger is located at the end of the printing component's movement path away from the transfer component. The cleaning member is located on the trigger. The rebound member is connected between the trigger and the frame.

[0016] When the printing component moves to the end of its movement path away from the transfer component, the printing component abuts against the trigger, and the trigger drives the cleaning component to move to the pressing surface of the printing component corresponding to the transfer component; when the printing component moves from the end of its movement path away from the transfer component toward the direction closer to the transfer component, the printing component separates from the trigger, and the spring pulls the trigger so that the cleaning component moves away from the pressing surface of the printing component corresponding to the transfer component.

[0017] Secondly, the present invention provides a tourniquet, which is manufactured by the tourniquet processing equipment described in the first aspect, and the tourniquet is printed with a colored pattern.

[0018] Furthermore, the tourniquet has colored patterns printed on both the front and back.

[0019] The tourniquet processing equipment of the present invention, through the cooperation of the transfer component and the substrate component, prints the colored patterns on the transfer paper onto the surface of the tourniquet, making the tourniquet more colorful and effective in diverting children's attention from treatment, reducing children's fear and anxiety during treatment, improving treatment efficiency, and making the treatment process smoother.

[0020] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the specification.

[0035] Please see Figures 1 to 3 , Figure 1 This is a first schematic diagram of the tourniquet 8 and transfer paper 9 before they are pressed together in the tourniquet processing equipment of this embodiment of the invention. Figure 2 for Figure 1 An enlarged schematic diagram of structure A. Figure 3This is a first schematic diagram of the tourniquet 8 and transfer paper 9 pressed together using a tourniquet processing device according to an embodiment of the present invention. The present invention provides a tourniquet processing device, including a frame 1, and a first conveying assembly 2, a second conveying assembly 3, a transfer assembly 4, and a receiving assembly 5 disposed on the frame 1. The first conveying assembly 2 is used to convey the transfer paper 9, and the second conveying assembly 3 is used to convey the tourniquet 8. Both the transfer paper 9 conveyed by the first conveying assembly 2 and the tourniquet 8 conveyed by the second conveying assembly 3 pass between the transfer assembly 4 and the receiving assembly 5. The transfer assembly 4 and / or the receiving assembly 5 are movable to allow the transfer paper 9 and the tourniquet 8 to be pressed together between the transfer assembly 4 and the receiving assembly 5. The transfer assembly 4 is used to heat the transfer paper 9 so that the colored pattern of the transfer paper 9 is transferred to the side where the tourniquet 8 and the transfer paper 9 are pressed together. Preferably, the transfer areas of the transfer paper 9 and the tourniquet 8 between the transfer assembly 4 and the substrate 5 are parallel to each other, and the normal vectors of the transfer paper 9 and the tourniquet 8 are also parallel to each other.

[0036] In some embodiments, the transfer assembly 4 and / or the substrate assembly 5 move vertically to move closer to or further away from each other, with their opposing pressing surfaces facing each other vertically. Preferably, in the vertical direction where the transfer assembly 4 and the substrate assembly 5 are located, the transfer paper 9 conveyed by the first conveying assembly 2 and the tourniquet 8 conveyed by the second conveying assembly 3 are both in a horizontal state.

[0037] Understandably, addressing the issue of existing tourniquets 8 having limited color options and lacking pattern design, this tourniquet processing equipment aims to efficiently and accurately print colorful patterns onto the surface of the tourniquet 8 using heat transfer technology. Heat transfer technology enables precise transfer of high-resolution, multi-color patterns, resulting in vibrant colors with strong adhesion, resistance to subsequent disinfection and friction during use, and particularly meeting the needs of children for fun patterns. Under the operation of this tourniquet processing equipment, the first conveying component 2 horizontally conveys the transfer paper 9 between the transfer component 4 and the substrate component 5, while the second conveying component 3 horizontally conveys the tourniquet 8 between the transfer component 4 and the substrate component 5. The transfer component 4 and / or the substrate component 5 move vertically, pressing the transfer paper 9 and the tourniquet 8 together. Then, the transfer component 4 heats the transfer paper 9, transferring the colorful pattern on the transfer paper 9 to the side of the tourniquet 8 where it is pressed against the transfer paper 9. The tourniquet processing equipment of this embodiment adds colorful patterns to the tourniquet 8, making its appearance more colorful. The tourniquet 8 with rich patterns can divert children's attention from treatment, reduce children's fear and anxiety during treatment, improve treatment efficiency, and make the treatment process smoother.

[0038] In some embodiments, the first conveying assembly 2 includes a first transfer roller 21 and a second transfer roller 22 rotatably disposed on the frame 1. Transfer paper 9 is connected between the first transfer roller 21 and the second transfer roller 22. The first transfer roller 21 is used to feed the transfer paper 9 out, and the second transfer roller 22 is used to rewind the transfer paper 9. The transfer assembly 4 is located on the side of the transfer paper 9 away from the tourniquet 8, and the transfer paper 9 and the tourniquet 8 are pressed together between the first transfer roller and the second transfer roller 22. Optionally, a tensioning roller can also be provided between the first transfer roller 21 and the second transfer roller 22 to tension the transfer paper 9. It should be explained that the first transfer roller 21 and the second transfer roller 22 can share a single drive motor, using a gear structure and / or a synchronous belt pulley structure to make the first transfer roller 21 and the second transfer roller 22 rotate synchronously; alternatively, the first transfer roller 21 and the second transfer roller 22 can each use their own matched drive motor, using a controller, frequency converter, encoder, or other components to make the first transfer roller 21 and the second transfer roller 22 rotate synchronously.

[0039] Understandably, the first conveying component 2 feeds the transfer paper 9 out through the first transmission roller 21, while the second transmission roller 22 is responsible for winding up the used transfer paper 9. During this process, the transfer paper 9 forms a horizontal conveying path between the first transmission roller 21 and the second transmission roller 22, ensuring that the transfer paper 9 can pass smoothly through the transfer area. The tension roller set between the first transmission roller 21 and the second transmission roller 22 can prevent the transfer paper 9 from becoming loose or wrinkled during the conveying process, thereby ensuring a tight fit between the transfer paper 9 and the tourniquet 8 and improving the effect of pattern transfer. The transfer component 4 is located on the side of the transfer paper 9 away from the tourniquet 8, and heats the transfer paper 9 to better transfer the colored pattern onto the tourniquet 8.

[0040] In some embodiments, the second conveying assembly 3 includes a mounting base 31 disposed on the frame 1, and a first roller group 32 and a second roller group 33 disposed on the mounting base 31; the mounting base 31 is provided with a first through hole 34, the first roller group 32 and the second roller group 33 are respectively disposed on both radial sides of the first through hole 34, and the tourniquet 8 passes through the first roller group 32, the first through hole 34 and the second roller group 33 in sequence; the first roller group 32 forms a first gap for the tourniquet 8 to pass through, and the first roller group 32 is used to make the tourniquet 8 passing through the first gap move toward the second roller group 33; the second roller group 33 forms a second gap for the tourniquet 8 to pass through, and the second roller group 33 is used to make the tourniquet 8 passing through the second gap move away from the first roller group 32; the printing assembly 5 is located on the side of the tourniquet 8 away from the transfer paper 9, and the transfer paper 9 and the tourniquet 8 are pressed together in the first through hole 34. Preferably, the mounting base 31 has a first through hole 34 with its axial direction vertical. The mounting base 31 also has a second through hole and a third through hole respectively connected to the first through hole 34. The second through hole allows the tourniquet 8 to pass through from one side of the mounting base 31 to the first through hole 34, and the third through hole allows the tourniquet 8 to pass through the first through hole 34 to the other side of the mounting base 31. Preferably, both the second and third through holes are perpendicular to the first through hole 34, and the second and third through holes are located on opposite radial sides of the first through hole 34. Specifically, the first roller group 32 is disposed in the second through hole, with a first gap located within the second through hole; the second roller group 33 is disposed in the third through hole, with a second gap located within the third through hole. Preferably, the first roller group 32 and the second roller group 33 can share a drive motor, and use a gear structure and / or a synchronous belt pulley structure to make the first transmission roller 21 and the second transmission roller 22 rotate synchronously; the first roller group 32 and the second roller group 33 can also use their own matched drive motors, and use a controller, frequency converter, encoder and other components to make the first roller group 32 and the second transmission roller 22 rotate synchronously.

[0041] In one feasible implementation, the tourniquet 8 enters the mounting base 31 from the outside through the second through hole. After entering the mounting base 31, the tourniquet 8 passes through the first gap of the first roller group 32, is guided by the first roller group 32, and moves towards the second roller group 33. Then, the tourniquet 8 continues to move towards the second roller group 33 through the first through hole 34. After reaching the second roller group 33, the tourniquet 8 passes through the second gap, is guided by the second roller group 33, and moves away from the first roller group 32, finally exiting the mounting base 31 through the third through hole, completing the conveying process in the second conveying assembly 3. While the tourniquet 8 is passing through the first through hole 34, the transfer paper 9 is also conveyed to this location. The transfer assembly 4 and / or the printing assembly 5 move vertically, pressing the transfer paper 9 and the tourniquet 8 together at the first through hole 34. The transfer assembly 4 heats the transfer paper 9, transferring the colored pattern on the transfer paper 9 to the side where the tourniquet 8 and the transfer paper 9 are pressed together.

[0042] In some embodiments, the transfer assembly 4 and the substrate assembly 5 are respectively disposed on both axial sides of the first through hole 34, and the transfer assembly 4 and the substrate assembly 5 move along the axial direction of the first through hole 34 to move closer to or further away from each other. The intersection of the movement of the transfer assembly 4 and the substrate assembly 5 is located inside the first through hole 34. It can be understood that, with the transfer assembly 4 and the substrate assembly 5 respectively located on both axial sides of the first through hole 34, through relative movement along the axial direction, when they move closer to each other, the transfer paper 9 and the tourniquet 8 are pressed together inside the first through hole 34. The transfer assembly 4 heats the transfer paper 9, allowing the colored pattern to be accurately transferred onto the tourniquet 8. After the transfer is completed, the transfer assembly 4 and the substrate assembly 5 move further away from each other along the axial direction, ready for the next transfer.

[0043] In some embodiments, a flipping assembly 6 is also included. The mounting base 31 is rotatably connected to the frame 1. The flipping assembly 6 is used to drive the mounting base 31 to flip, thereby causing the first roller group 32, the second roller group 33 and the tourniquet 8 located between the first roller group 32 and the second roller group 33 to flip. The single flipping angle of the mounting base 31 driven by the flipping assembly 6 is 180°.

[0044] In one feasible implementation, the tourniquet 8 is first conveyed to the transfer area via the second conveying assembly 3, passing through the first roller group 32, the first through hole 34, and the second roller group 33, where it is pressed against the transfer paper 9 at the first through hole 34, completing the pattern transfer on one side. When it is necessary to transfer the other side of the tourniquet 8, the flipping assembly 6 is activated, driving the mounting base 31 to rotate 180° around its rotational connection axis with the frame 1. During the flipping process, the first roller group 32, the second roller group 33, and the tourniquet 8 located between them are flipped together, so that the other side of the tourniquet 8 faces the transfer assembly 4. After the flipping is completed, the first conveying assembly 2 continues to convey the transfer paper 9, causing it to pass through the transfer area again. The transfer assembly 4 and the printing assembly 5 press the transfer paper 9 and the tourniquet 8 together again, completing the pattern transfer on the other side of the tourniquet 8. In this embodiment, by realizing double-sided color printing of the tourniquet 8, its appearance can be made more colorful, which can better attract the attention of special groups such as children, improve the aesthetics and attractiveness of the product, and increase the added value of the product.

[0045] Furthermore, the mounting base 31 is provided with a first flip trigger button and a second flip trigger button on the surfaces of both sides along the axial direction of the first through hole 34; the transfer assembly 4 includes a hot press plate 41 that moves along the central axis of the first through hole 34, and a connecting plate 42 disposed on the side of the hot press plate 41 away from the mounting base 31; the printing assembly 5 includes a printing plate 51 that moves along the central axis of the first through hole 34; when the hot press plate 41 and the printing plate 51 approach each other and extend into the first through hole 34 to press the transfer paper 9 and the tourniquet 8 therein, the connecting plate 42 presses the first flip trigger button or the second flip trigger button; when the hot press plate 41 and the printing plate 51 move away from each other and disengage from the first through hole 34, the connecting plate 42 releases the first flip trigger button or the second flip trigger button that it has pressed; when the first flip trigger button or the second flip trigger button experiences one press and release, the flipping assembly 6 drives the mounting base 31 to flip.

[0046] It is understandable that closely linking the flipping action with the actions of the transfer assembly 4 and the substrate assembly 5 ensures that the equipment can automatically trigger the flipping action after each transfer, preparing for the next transfer. This precise coordination and control helps improve transfer quality and avoids transfer problems caused by human operation delays or premature actions. In one feasible implementation, the mounting base 31 is initially in its initial position, with neither the first nor the second flipping trigger button pressed, and the hot press plate 41 and the substrate plate 51 in a separated state. During the transfer preparation, the transfer paper 9 and the tourniquet 8 are conveyed to the first through hole 34, ready for transfer. The hot press plate 41 and the substrate plate 51 approach each other along the central axis of the first through hole 34, extending into the first through hole 34 to press the transfer paper 9 and the tourniquet 8 together. At this time, the connecting plate 42 presses either the first or second flipping trigger button, depending on the current transfer surface. When the hot press plate 41 and the printing plate 51 complete pressing and move away from each other, disengaging from the first through hole 34, the connecting plate 42 releases the pressed first trigger button 35 or second trigger button 36. After one pressing and releasing, the first trigger button 35 or second trigger button 36 sends a signal to the flipping assembly 6, driving the mounting base 31 to rotate 180°, so that the other side of the tourniquet 8 faces the transfer assembly 4. After the mounting base 31 has rotated, the tourniquet 8 remains stationary, the transfer paper 9 is fed to the transfer area again, and the hot press plate 41 and the printing plate 51 press together again to complete the pattern transfer on the other side of the tourniquet 8.

[0047] In some embodiments, the structure for driving the transfer assembly 4 to move can be a telescopic component such as a cylinder or hydraulic cylinder, a lead screw and nut mechanism, or a linear motor. For example, the structure for driving the transfer assembly 4 to move is a cylinder, that is, the transfer assembly 4 includes a cylinder, and a connecting plate 42 is installed on the telescopic end of the cylinder relative to the printing assembly 5. A hot press plate 41 is connected to one side of the connecting plate 42 relative to the printing assembly 5. When the cylinder works, it drives the transfer assembly 4 to move closer to or away from the first through hole 34 along the axial direction of the first through hole 34. For example, the structure for driving the transfer assembly 4 to move is a lead screw and nut mechanism. That is, the transfer assembly 4 includes a lead screw, a nut, and a drive motor. The drive motor is mounted on the frame 1. The lead screw is arranged along the axial direction of the first through hole 34 and is transmitted to the output end of the drive motor. The nut is threadedly engaged with the lead screw and fixedly connected to the connecting plate 42. A hot press plate 41 is connected to the side of the connecting plate 42 opposite to the printing assembly 5. A moving track is also provided on the frame 1, and the connecting plate 42 is slidably connected to the moving track. When the drive motor operates, the lead screw rotates, causing the nut to drive the connecting plate 42 to move along the lead screw to approach or move away from the first through hole 34. The connecting plate 42 then drives the hot press plate 41 to move. Optionally, the structure for driving the printing assembly 5 to move is the same as the structure for driving the transfer assembly 4 to move.

[0048] Please see Figure 4 and Figure 5 , Figure 4 This is a second schematic diagram of the tourniquet 8 and transfer paper 9 before they are pressed together in the tourniquet processing equipment of this embodiment of the invention. Figure 5 This is a second schematic diagram of the tourniquet 8 and transfer paper 9 pressed together in the tourniquet processing equipment of this embodiment of the invention. The movement path of the printing component 5 is provided with a cleaning component 7. When the printing component 5 moves away from the transfer component 4 and passes the cleaning component 7, the cleaning component 7 cleans the pressing surface of the printing component 5 corresponding to the transfer component 4.

[0049] It is understandable that during the transfer process, the pressing surface of the printing component 5 may become contaminated with residues, dust, or other impurities from the transfer paper 9. These impurities can affect the quality of subsequent transfers, leading to unclear patterns or defects. This embodiment addresses this by providing a cleaning component 7, which automatically cleans the printing component 5 after each transfer operation, ensuring the pressing surface remains clean and guaranteeing the stability and consistency of transfer quality. In one feasible implementation, after completing one transfer operation, the printing component 5 moves along its movement path away from the transfer component 4, preparing for the next transfer cycle. When the printing component 5 reaches the position of the cleaning component 7, the cleaning component 7 is triggered and begins cleaning the pressing surface of the printing component 5. The cleaning component 7 can thoroughly clean the pressing surface of the printing component 5 through physical wiping, chemical cleaning, or other methods, removing surface dust, residues, and other impurities. The printing component 5 continues to move along its movement path to deactivate the cleaning component 7, which automatically resets, waiting for the next time the printing component 5 passes by to perform cleaning again.

[0050] Furthermore, the cleaning component 7 includes a trigger 71, a return spring, and a cleaning component 72. The trigger 71 is located at the end of the movement path of the printing component 5 away from the transfer component 4. The cleaning component 72 is located on the trigger 71. The return spring is connected between the trigger 71 and the frame 1. When the printing component 5 moves to the end of its movement path away from the transfer component 4, the printing component 5 abuts against the trigger 71. The trigger 71 drives the cleaning component 72 to move to the pressing surface of the printing component 5 corresponding to the transfer component 4. When the printing component 5 moves from the end of its movement path away from the transfer component 4 toward the direction closer to the transfer component 4, the printing component 5 separates from the trigger 71. The return spring pulls the trigger 71 so that the cleaning component 72 is removed from the pressing surface of the printing component 5 corresponding to the transfer component 4.

[0051] Optionally, the cleaning component 72 can be a brush, the trigger 71 is a lever structure, and the return element is a torsion spring, with the return element located at the rotatable connection between the trigger 71 and the frame 1. When the printing assembly 5 moves to the end of its movement path away from the transfer assembly 4, it abuts against one end of the trigger 71. The other end of the trigger 71 drives the brush to move to the pressing surface of the printing assembly 5.
