Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a tourniquet with a time recording function. Background Technology

[0002] A tourniquet is a medical device used to stop bleeding and is widely used in the medical field. During procedures such as blood collection, intravenous infusion, and blood transfusion, a tourniquet is used to temporarily block blood circulation in the limb to facilitate the procedure. However, most tourniquets on the market currently have limited functions, only providing basic hemostasis and unable to record the duration of hemostasis. In practice, medical staff need to manually record the hemostasis time, which not only increases their workload but also increases the risk of inaccurate recording. If the hemostasis time is too long, it may lead to serious consequences such as limb ischemia and necrosis; if the hemostasis time is too short, it may not achieve the desired effect, leading to uncontrollable bleeding.

[0003] For example, patent CN219354052U discloses a tourniquet, including: a tourniquet body, connecting components, and pressure-applying components. The tourniquet body has a first connecting component and a second connecting component connected to its two ends along its length. There are two pressure-applying components, which are spaced apart along the length of the tourniquet body. The first connecting component and the second connecting component can be connected to each other so that the two ends of the tourniquet body are connected to form a closed loop, thereby enabling the tourniquet body to be wrapped around the patient's abdomen. The two pressure-applying components can correspond to the two ends of the artificial blood vessel, respectively. The user presses the pressure-applying components to press the two ends of the artificial blood vessel to improve the hemostatic effect and avoid bleeding, hematoma, infection, etc.

[0004] However, its technology has the following problems:

[0005] First, relying solely on pressure-applying components makes it difficult to accurately apply pressure to the wound, resulting in poor hemostasis.

[0006] Secondly, the device does not have a wear time recording function, making it impossible to accurately determine the duration of hemostasis of the wound.

[0007] Based on this, the present invention designs a tourniquet with time recording function to solve the above problems. Utility Model Content

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tourniquet with time recording function.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A tourniquet with time recording function includes a tourniquet body, a fixing buckle, a twisting rod, a fixing ring, a first buckle, a second buckle, a time recording module, and a fixing strap;

[0011] The tourniquet body is fixedly equipped with a fixing ring and a fixing buckle. The two ends of the tourniquet body are detachably connected by a first buckle and a second buckle. A connecting strap is fixedly installed at one end of the tourniquet body. The twisting bar is fixedly connected to the connecting strap. The time recording module is snapped onto the bottom front side of the fixing ring. The twisting bar can be snapped onto the fixing buckle. There are two fixing straps, both of which are fixedly installed on the inner side of the tourniquet body in accordance with the position of the twisting bar.

[0012] The time recording module includes an adjustment component and a locking component. The adjustment component is snapped onto the bottom front side of the fixed ring, and the adjustment component is connected to the locking component.

[0013] Furthermore, it also includes a handwriting strip, which is detachably mounted on the top of the front side of the retaining ring.

[0014] Furthermore, the adjustment component includes a main structure and a limiting structure, with the main structure and the limiting structure connected together.

[0015] Furthermore, the main structure includes an elastic buckle, an outer shell, and a dial. One end of the elastic buckle is fixedly connected to the rear side of the outer shell, and the elastic buckle is snapped into the bottom front side of the fixing ring. Multiple dials are provided at equal intervals and are all connected to the inside of the outer shell through damping rotation.

[0016] Furthermore, the outer casing is connected to a locking assembly.

[0017] Furthermore, the dial has ten surfaces on its circumferential side, and each surface has a recess in the shape of a number.

[0018] Furthermore, the limiting structure includes a pull rod and a pull ring. The pull rod is slidably disposed inside the outer shell, and multiple dials are sleeved on the outer side of the end of the pull rod. The inner wall of the dial is slidably connected to the outer wall of the pull rod. A through hole is opened on the outer wall of the right end of the pull rod. Multiple grooves are equally spaced on the outer wall of the end of the pull rod located inside the outer shell. The inner wall of the dial is rotatably connected to the grooves. The right end of the pull rod extends to the outer side of the right end of the outer shell and is fixedly connected to the pull ring.

[0019] Furthermore, the through hole is connected to the locking assembly.

[0020] Furthermore, the locking component includes a slot and a groove, both of which are located on the right side of the outer casing, and the slot and groove are connected.

[0021] Furthermore, the locking assembly also includes a limiting rod, a spring, and an adjusting block. The limiting rod is slidably disposed inside the slot. The inner wall of the slot is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one end of the limiting rod. The other end of the limiting rod can be inserted into the through hole for locking connection. One end of the adjusting block slides through the slot, extends into the slot, and is fixedly connected to the outer wall of the limiting rod.

[0022] Compared with the prior art, the advantages of this utility model are as follows:

[0023] 1. This utility model allows users to record the tourniquet usage time either by handwriting on the tape or by adjusting the dial. These two recording methods provide caregivers with more options to meet different usage habits and scenario needs, helping to accurately record the tourniquet usage duration and providing important reference for subsequent medical treatment.

[0024] 2. This device, by pushing the lever back to its original position, can limit the movement of the dial's inner wall, effectively preventing accidental rotation of the dial due to external force and thus ensuring the accuracy of recorded time. Simultaneously, the limiting lever automatically engages with the through hole to fix the lever under spring action, further enhancing the stability of the entire device. This ensures reliable time recording in various environments, avoiding errors caused by loosening or misoperation, and improving the overall practicality and safety of the device.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to... Figure 3 The direction of the viewpoint.

[0038] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A tourniquet with time recording function includes a tourniquet body 1, a fixing buckle 2, a twisting bar 3, a fixing ring 4, a first buckle 5, a second buckle 6, a handwriting tape 7, a time recording module 8, and a fixing tape 9.

[0039] Specifically, a fixing ring 4 and a fixing buckle 2 are fixedly installed on the tourniquet body 1. The two ends of the tourniquet body 1 are detachably connected by a first buckle 5 and a second buckle 6. A connecting strap 10 is fixedly installed on one end of the tourniquet body 1. The twisting rod 3 is fixedly connected to the connecting strap 10. The time recording module 8 is snapped onto the bottom front side of the fixing ring 4. The twisting rod 3 can be snapped onto the fixing buckle 2. Two fixing straps 9 are provided, both of which are fixedly installed on the inner side of the tourniquet body 1 to match the position of the twisting rod 3. Among them, the first buckle 5 and the second buckle 6 are both D-ring buckles.

[0040] The time recording module 8 includes an adjustment component 81 and a locking component 82. The adjustment component 81 is snapped onto the bottom front side of the fixing ring 4, and the adjustment component 81 is connected to the locking component 82. L-shaped blocks are fixedly installed at both the upper and lower ends of the fixing buckle 2, and the two L-shaped blocks are respectively snapped onto both ends of the winch 3.

[0041] The handwriting tape 7 is detachably mounted on the top front side of the fixing ring 4. A Velcro strip is installed on the top front side of the fixing ring 4, and a Velcro strip is installed on the back side of the handwriting tape 7. The Velcro strip and the Velcro strip are detachably connected.

[0042] In use, after the patient initially places the tourniquet body 1 on a suitable position above the limb wound, the monitoring personnel immediately unfold both ends for fixation. The first buckle 5 has a rectangular sheet structure, and its main body is made of sturdy metal or high-strength plastic with a non-slip surface. The first buckle 5 is installed at one end of the tourniquet body 1, and the second buckle 6 has a similar structure to the first buckle 5, but is located at the other end of the tourniquet body 1.

[0043] During the fixation process, first pick up the tourniquet body 1, pass the end with the second buckle 6 through the first buckle 5, and then insert the end back into the second buckle 6 to complete the adjustment and initially fix the tourniquet; then, firmly attach the end with the second buckle 6 to the outer part of the tourniquet body 1 with Velcro to achieve a stable fixation and ensure that the tourniquet will not loosen or shift during use.

[0044] After initial fixation, since there will be a gap between the tourniquet body 1 and the limb, the wrench 3 is rotated again. The wrench 3 drives the connecting strap 10 to further tighten and reinforce the tourniquet body 1. Then, one end of the wrench 3 is engaged with one end of the fixing buckle 2 to prevent the tourniquet pressure from loosening. At the same time, the monitoring personnel use the two fixing straps 9 equipped on the inner side of the tourniquet body 1 to wrap around the upper and lower ends of the wrench 3 and tie them together. This makes the ends of the two fixing straps 9 close to each other and squeeze the upper and lower ends of the wrench 3, thereby further fixing the wrench 3.

[0045] This dual fixation method enhances the overall stability of the tourniquet, ensuring continuous and stable wound compression even when the patient's limbs move or are in complex environments such as bumpy conditions, creating favorable and stable conditions for wound hemostasis. The monitoring personnel can then record the time by handwriting on the writing tape 7 or by adjusting the dial 813, thus recording the usage time of the tourniquet body 1.

[0046] In this utility model, the monitoring personnel can record the tourniquet usage time either by handwriting on the handwriting tape 7 or by adjusting the dial 813. These two recording methods provide the monitoring personnel with more options to meet different usage habits and scenario needs, and help to accurately record the tourniquet usage duration, providing an important reference for subsequent medical treatment.

[0047] Example 2: In some embodiments, such as Figures 2-8 As shown, in a preferred embodiment of the present invention, the adjustment component 81 includes a main structure and a limiting structure, and the main structure and the limiting structure are connected.

[0048] Specifically, the main structure includes a flexible buckle 811, a housing 812, and a dial 813. One end of the flexible buckle 811 is fixedly connected to the rear side of the housing 812, and the flexible buckle 811 is engaged with the bottom front side of the fixing ring 4. Multiple dials 813 are evenly spaced and are all connected to the inside of the housing 812 via damped rotation. The housing 812 is connected to the locking assembly 82. The circumferential side of the dial 813 has ten faces, each with a numerical recess representing the numbers 0-9.

[0049] The limiting structure includes a pull rod 815 and a pull ring 817. The pull rod 815 is slidably disposed inside the outer casing 812, and multiple dials 813 are sleeved on the outer side of the end of the pull rod 815. The inner wall of the dial 813 is slidably connected to the outer wall of the pull rod 815. A through hole 814 is provided on the outer wall of the right end of the pull rod 815 inside the outer casing 812. Multiple grooves 816 are equally spaced on the outer wall of the end of the pull rod 815 inside the outer casing 812. The inner wall of the dial 813 is rotatably connected to the grooves 816. The right end of the pull rod 815 extends to the outer side of the right end of the outer casing 812 and is fixedly connected to the pull ring 817. The through hole 814 is connected to the locking assembly 82. The inner wall of the dial 813 cannot rotate relative to the outer wall of the pull rod 815; the dial 813 can only rotate when the inner wall of the dial 813 corresponds to the position of the groove 816.

[0050] The locking component 82 includes a slot 821 and a slot 824. Both the slot 821 and the slot 824 are located on the right side of the outer casing 812, and the slot 821 and the slot 824 are connected.

[0051] The locking assembly 82 also includes a limiting rod 822, a spring 823, and an adjusting block 825. The limiting rod 822 is slidably disposed inside the slot 821. The inner wall of the slot 821 is fixedly connected to one end of the spring 823, and the other end of the spring 823 is fixedly connected to one end of the limiting rod 822. The other end of the limiting rod 822 can be inserted into the through hole 814 for locking connection. One end of the adjusting block 825 slides through the slot 824, extends into the slot 821, and is fixedly connected to the outer wall of the limiting rod 822.

[0052] In use, this invention first slides the adjusting block 825, causing the adjusting block 825 to move the limiting rod 822 away from the pull rod 815. At this time, the spring 823 is compressed, causing the limiting rod 822 to disengage from the through hole 814, thus unlocking the pull rod 815. Then, the pull ring 817 is pulled outward, causing the pull ring 817 to move the pull rod 815 outward together, pushing the multiple grooves 816 on the pull rod 815 to the inner wall of the dial 813, thus removing the limiting effect of the pull rod 815. Next, the corresponding dial 813 is rotated to display the corresponding time. Then, the pull rod 815 is pushed back to its original position, so that the outer wall of the pull rod 815 limits the inner wall of the dial 813, preventing external force from accidentally rotating the dial 813 and changing the time, thus ensuring the accuracy of the time. Then, the limiting rod 822 is engaged in the through hole 814 under the action of the spring 823, fixing the pull rod 815.

[0053] This device, by pushing the pull rod 815 back to its original position, can limit the inner wall of the dial 813, effectively preventing accidental rotation of the dial 813 due to external force, thus ensuring the accuracy of recorded time. Simultaneously, the limiting rod 822 automatically engages with the through hole 814 under the elastic force of the spring 823, fixing the pull rod 815, further enhancing the stability of the entire device. This ensures reliable time recording in various environments, avoiding errors caused by loosening or misoperation, and improving the overall practicality and safety of the device.

[0054] Example 3: In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the cross-sectional shape of the outer wall of the pull rod 815 and the inner wall of the dial 813 are both polygonal, so that the pull rod 815 can prevent the dial 813 from rotating.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
