Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a reusable intelligent tourniquet. Background Art

[0002] In the field of medical emergency, rapid and effective hemostasis is the key to saving lives. Traditional hemostasis methods mainly rely on the experience and manual operations of medical staff, such as the use of physical compression methods such as bandages and gauze to stop bleeding. The lack of precise pressure control and duration recording may lead to excessive compression causing tissue damage, or insufficient compression leading to continued bleeding.

[0003] In order to overcome the limitations of traditional hemostasis methods, reusable intelligent hemostasis strips have appeared on the market. This hemostasis strip realizes the automation and precision of the hemostasis process by integrating advanced technologies such as sensors and microprocessors. It can automatically adjust the pressure according to the wound condition and record the duration of hemostasis, providing medical staff with a more accurate evaluation of the hemostasis effect.

[0004] However, existing reusable smart hemostatic strips still face some challenges in disinfection. In order to ensure the sterility of the hemostatic strips when they are used next time, they are usually disinfected with ultraviolet lamps or other chemical disinfectants; although ultraviolet lamp disinfection is effective, there are some obvious problems. First, ultraviolet lamps require a certain exposure time and intensity to achieve the desired disinfection effect, which may delay precious treatment time in emergency situations. Secondly, ultraviolet lamps have a limited service life and require regular maintenance and replacement, which not only increases the cost of use, but may also cause injuries to medical staff due to improper operation, because ultraviolet rays are harmful to human skin. In addition, when using hemostatic strips outdoors or in special environments, it is more difficult to create a suitable disinfection environment, making the disinfection process more complicated and difficult; in particularly urgent situations, medical staff may have to use unsterilized hemostatic strips to stop bleeding, which undoubtedly increases the risk of cross-infection.

[0005] Therefore, although the existing reusable intelligent hemostatic strips have improved the hemostatic efficiency to a certain extent, there are still many inconveniences and limitations in the disinfection process. In order to solve these problems, it is necessary to develop a more efficient and convenient reusable intelligent hemostatic strip. Summary of the invention

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-Figure 4 As shown, a reusable intelligent tourniquet comprises a mounting shell 1, a hemostatic strip 2 and a protective cover 3; the mounting shell 1 is hollow inside and is rotatably provided with a first rotating shaft 11 and a second rotating shaft 12; the hemostatic strip 2 is mounted on the first rotating shaft 11, and the protective cover 3 is mounted on the second rotating shaft 12; an outlet 13 is also provided on one side of the mounting shell 1, and the outlet 13 is connected to the inside of the mounting shell 1, and the hemostatic strip 2 is unwound outwardly and reeled inwardly at the outlet 13; a creasing mechanism 5 is provided on the upper part of the outlet 13, and the creasing mechanism 5 is used to fold the flat protective cover 3 into the shape of the protective cover 3 and put the protective cover 3 on the unwound hemostatic strip 2; a clamping component 4 is also provided on the other side of the mounting shell 1, and the clamping component 4 is used to clamp the unwound hemostatic strip 2.

[0029] When it is needed, the hemostatic strip 2 is unwound outward through the outlet 13, and at the same time, the creasing mechanism 5 folds the flat disposable protective cover 3 into a shape matching the hemostatic strip 2, and automatically puts it on the unwound hemostatic strip 2; in this process, no human intervention is required, and the protective cover 3 is quickly and accurately put on; after the first use, since the protective cover 3 is disposable, it can be discarded directly, avoiding the risk of cross infection; at the same time, due to the presence of the protective cover 3, the hemostatic strip 2 itself does not need to undergo a cumbersome ultraviolet disinfection process, thereby saving disinfection time and equipment costs; after the hemostatic strip 2 is unwound and the protective cover 3 is put on, the clamping assembly 4 is used to fix the hemostatic strip 2 to ensure that it will not accidentally fall off or loosen during use.

[0030] In summary, the indentation mechanism 5 of the present application can put the flat protective cover 3 on the hemostatic strip 2 to isolate the section of the hemostatic strip 2 used for binding, and the protective cover 3 can change its own state according to the use state of the hemostatic strip 2, that is, when the hemostatic strip 2 is unwound, the first rotating shaft 11 serves as a rotating wheel, and the second rotating shaft 12 serves as a passive wheel. When the hemostatic strip 2 is unwound, the protective cover 3 is also unwound and put on the hemostatic strip 2 accordingly to isolate the hemostatic strip 2 from the use environment; and when the hemostatic strip 2 is reeled in, the used protective cover 3 can be separated from the hemostatic strip 2 and will not be reeled with the hemostatic strip 2. When the hemostatic strip 2 is completely reeled in, the protective cover 3 outside the outlet 13 can be cut off, and there is no need to go through cumbersome work processes such as cleaning or disinfecting the hemostatic strip 2, thereby improving the convenience and safety of the hemostatic strip 2.

[0031] In one embodiment, the indentation mechanism 5 includes a profiling frame 51, a pressure roller 52 and a transmission member 53; the profiling frame 51 is arranged at the outlet 13, and the top is connected to the top of the outlet 13, the profiling frame 51 is an enlarged version of the profiling of the hemostatic strip 2, the hemostatic strip 2 slides on the inner side of the profiling frame 51, and the protective cover 3 is arranged on the outer side of the profiling frame 51 to ensure that the hemostatic strip 2 can maintain a stable path when sliding on the inner side of the profiling frame 51. At the same time, the space outside the profiling frame 51 provides convenience for the installation of the protective cover 3, and the flat protective cover 3 is folded through the profiling frame 51 and then bonded to the protective cover 3; according to the unwinding direction of the hemostatic strip 2, the pressure roller 52 is slidably arranged on the mounting shell 1 and is located at the front end of the profiling frame 51, and the transmission member 53 The pressing roller 52 is driven to make intermittent up and down movements, and the protective sleeve 3 is located between the pressing roller 52 and the hemostatic strip 2. The pressing roller 52 is used to bond the protective sleeve 3 to the hemostatic strip 2. Driven by the transmission member 53, the pressing roller 52 can make intermittent up and down movements, so that the pressing roller 52 can press the protective sleeve 3 when unwinding, thereby tightly bonding it to the hemostatic strip 2; that is, when the hemostatic strip 2 is unwound outward from the outlet 13, it will slide along the inner side of the profiling frame 51. At the same time, the protective sleeve 3 is placed on the outer side of the profiling frame 51 and gradually unfolds as the hemostatic strip 2 moves. When the protective sleeve 3 is located at the lower position of the pressing roller 52, the pressing roller 52 will move downward again driven by the transmission member 53, and press the protective sleeve 3 tightly against the hemostatic strip 2 to achieve bonding between the two.

[0032] In one embodiment, the transmission member 53 includes a first transmission rod 531, a second transmission rod 532, a round tooth 533 and a straight tooth 534; one end of the first transmission rod 531 is connected to the rear end of the second transmission rod 532, and the other end is cleverly arranged on the outer ring of the second rotating shaft 12; thus, when the second rotating shaft 12 rotates, the first transmission rod 531 will also rotate accordingly; the second transmission rod 532: is rotatably arranged in the mounting shell 1, one end of which is connected to the first transmission rod 531, and the other end is provided with a round tooth 533; the round tooth 533 is arranged at the other end of the second transmission rod 532, and a vertical connecting portion is provided on the top of the pressure roller 52, and a straight tooth matching the round tooth 533 is provided on the connecting portion 534; when the round teeth 533 and the straight teeth 534 are meshed, they can transmit power to each other; when the protective sleeve 3 is unwound, the second rotating shaft 12 will rotate accordingly; since one end of the first transmission rod 531 is connected to the outer ring of the second rotating shaft 12, the first transmission rod 531 will also rotate with the rotation of the second rotating shaft 12; the rotation of the first transmission rod 531 will drive the second transmission rod 532 to rotate together, and due to the meshing relationship between the round teeth 533 and the straight teeth 534, when the second transmission rod 532 swings up and down at a fixed point, the round teeth 533 will push the straight teeth 534 to move intermittently upward and downward, so that the pressure roller 52 makes intermittent motion in the vertical direction, and the protective sleeve 3 is bonded to the hemostatic strip 2 at intervals.

[0033] In one embodiment, the hemostatic strip 2 is located on the top of the protective cover 3. When the hemostatic strip 2 is located on the top of the protective cover 3, the protective cover 3 can be wrapped upward from the bottom of the hemostatic strip 2, thereby completely covering the entire surface of the hemostatic strip 2. This wrapping method ensures that the hemostatic strip 2 will not directly contact the patient's skin or wound during use, effectively reducing the risk of cross infection.

[0034] In one embodiment, the snap-fit ​​assembly 4 includes a snap-fit ​​seat 41, a snap-fit ​​joint 42 and a spring 43; the snap-fit ​​seat 41 is arranged on one side of the mounting shell 1 and is opposite to the outlet 13; the snap-fit ​​joint 42 is fixedly connected to the hemostatic strip 2, and the hemostatic strip 2 is snap-fitted to the snap-fit ​​seat 41 through the snap-fit ​​joint 42; snap-fit ​​portions 421 are also rotatably arranged on both sides of the snap-fit ​​joint 42, and the spring 43 is arranged between the snap-fit ​​seat 41 and the snap-fit ​​portion 421, and the spring 43 is arranged on the side opposite to the rotation point of the snap-fit ​​portion 421; when the snap-fit ​​portion 421 is not acted upon by external force, due to the action of the spring 43, it will maintain an outwardly opened state, and when the snap-fit ​​joint 42 is inserted into the snap-fit ​​seat 41, the snap-fit ​​portion 421 will be squeezed by the inner wall of the snap-fit ​​seat 41 and begin to shrink. When the clamping joint 42 completely enters the clamping seat 41, the clamping part 421 will return to its original open state under the action of the spring 43, and thus be locked in the clamping seat 41, thereby fixing the hemostatic strip 2; the spring 43 is cleverly arranged between the clamping seat 41 and the clamping part 421, and is located on the opposite side of the rotation point of the clamping part 421; the elastic force of the spring 43 provides the clamping part 421 with the necessary restoring force, ensuring that the clamping part 421 can automatically open and lock after insertion; at the same time, the presence of the spring 43 also makes the clamping process smoother, reducing friction and resistance.

[0035] In one embodiment, the clamping assembly 4 also includes an anchoring assembly, which anchors the protective cover 3 to the clamping assembly 4; the anchoring assembly includes an anchoring spring 61 and a ratchet hook 62; the ratchet hook 62 is arranged on the clamping seat 41, and along the direction in which the clamping joint 42 is clamped with the clamping seat 41, the rotation point of the ratchet hook 62 is arranged on the outside, and the ratchet hook 62 extends inward; the anchoring spring 61 is arranged on the end of the ratchet hook 62 away from the rotation point, connecting the ratchet hook 62 with the clamping seat 41, and the ratchet hook 62 is used to transfer the protective cover 3 of the hemostatic strip 2 to the ratchet hook 62; when the hemostatic strip 2 is clamped to the clamping seat 41 from the outside to the inside, the ratchet hook 62 abuts against the clamping portion 421, and the compression spring 43 fits against the side wall of the clamping seat 41, When the hemostatic strip 2 leaves the clamping seat 41 from the inside to the outside, the mechanism gradually rotates to one side of the hemostatic strip 2 under the action of the spring 43, and the protective cover 3 is hooked by the ratchet hook 62 during the outward movement, and is anchored to one end of the clamping seat 41 by the ratchet hook 62. As the hemostatic strip 2 is continuously rolled up, the protective cover 3 sleeved on the hemostatic strip 2 is continuously separated from the hemostatic strip 2, thereby separating the used protective cover 3 from the hemostatic strip 2. Furthermore, when the hemostatic strip 2 is completely rolled up, the protective cover 3 at the outlet 13 is cut off, thereby completely recycling and discarding the used protective cover 3, and the protective cover 3 that is not rolled up on the second rotating shaft 12 can continue to be sleeved on the hemostatic strip 2 when the hemostatic strip 2 is used next time, thereby solving the risk of contamination of the hemostatic strip 2 and eliminating the workflow of cleaning and disinfecting the hemostatic strip 2.

[0036] In one embodiment, it also includes a main control unit and a timer module, and the timer module is electrically connected to the main control unit. When the hemostatic strip 2 is snapped into the snap-in assembly 4, the timer module starts timing and uploads the timing to the main control unit. When the timing ends, the main control unit sends an instruction to the timer module to separate the hemostatic strip 2 from the snap-in assembly 4. This can control the timing time of the hemostatic strip 2 and provide timely information for staff or the injured to check the hemostasis situation.

[0037] In one embodiment, the main control unit includes a coil 71, an armature 72, a plurality of wires 73 and a battery; the coil 71 is connected with the wires 73 to form a main circuit, and the battery is used to supply power to the main circuit; the coil 71 is arranged on the clamping seat 41, the timer module is installed on the clamping seat 41, another wire 73 is connected in series with the timer module to form a normally open circuit, the armature 72 is arranged in series in the normally open circuit, and the coil 71 is energized to attract the armature 72 to form a closed circuit; the coil 71 is arranged on the clamping seat 41, and when the hemostatic strip 2 is clamped on the clamping assembly 4, the coil 71 is energized. When the coil 71 is energized, a magnetic field will be generated, and this magnetic field will attract the armature 72, causing it to change from a normally open state to a closed state. When the armature 72 is attracted, the normally open circuit becomes a closed circuit, and the timer module is powered and starts timing. The timer module will feed back the timing information to the main control unit in real time. When the timer module reaches the preset timing time, it will send a stop signal to the main control unit. After receiving the stop signal, the main control unit will cut off the power supply of the main circuit, the coil 71 will lose power, the magnetic field will disappear, and the armature 72 will return to the normally open state under the action of the spring 43. The normally open circuit is disconnected and the timer module stops working.

[0038] In one embodiment, it also includes a pressure sensor 81 and a display screen; the pressure sensor 81 is arranged on the side of the mounting shell 1 that contacts the human body, the pressure sensor 81 is used to monitor the pressure of the hemostatic strip 2 when it is tied and upload it to the main control unit, the display screen is electrically connected to the main control unit, the display screen is arranged on a side adjacent to the pressure sensor 81, and the main control unit displays the pressure monitored by the pressure sensor 81 through the display screen; the pressure sensor 81 is arranged on the side of the mounting shell 1 that contacts the human body, and when the hemostatic strip 2 is tied on the human body, the pressure sensor 81 can sense the pressure generated by the binding. This pressure signal will be converted into an electrical signal and uploaded to the main control unit. After receiving the electrical signal uploaded by the pressure sensor 81, the main control unit will process and convert the signal and convert it into a recognizable pressure value. The display screen is electrically connected to the main control unit and is arranged on a side adjacent to the pressure sensor 81 so that medical staff can intuitively see the pressure value. Medical staff can judge whether the binding pressure of the hemostatic strip 2 is appropriate based on the pressure value displayed on the display screen; if the pressure is too high or too low, the binding strength of the hemostatic strip 2 can be adjusted in time to ensure the patient's comfort and good hemostasis effect.

[0039] In one embodiment, an adhesive layer is provided on one side of the protective cover 3 and the hemostatic strip 2, and the adhesive layer is used to fix the protective cover 3 on the hemostatic strip 2. The adhesive layer is pre-set on the inner side of the protective cover 3, i.e., the side in contact with the hemostatic strip 2; the adhesive layer includes but is not limited to adhesives, double-sided tapes or other sticky materials.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
