Technical Field
[0001] The utility model relates to the technical field of tourniquets, in particular to an emergency tourniquet. Background Art
[0002] The tourniquet is made of medical polymer material natural rubber or special rubber, and is long and flat with strong elasticity. It is suitable for medical institutions for infusion, blood drawing, blood transfusion, and one-time use in hemostasis during routine treatment and rescue, or for emergency hemostasis in case of limb bleeding or snake and insect bites in the wild.
[0003] Existing tourniquets apply pressure to the tourniquet by rotating the spinning rod, so that the wound is subjected to compression force to stop bleeding. However, the pressure state of the wound cannot be observed when the spinning rod is rotated, so the pressure applied by the spinning rod may be too great, causing excessive compression and necrosis of the wound veins. In addition, the hemostasis time cannot be accurately controlled, resulting in excessive compression time, which may cause local tissue damage in the wound and obstruct blood circulation.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes an emergency tourniquet.
[0021] See also Figures 1-4 , an emergency tourniquet includes a transparent hemostatic plate 1, a fixed block 101 is fixedly installed at the bottom of the transparent hemostatic plate 1, a rotating rod 102 is rotatably installed inside the fixed block 101, a threaded groove 103 is provided at the bottom of the rotating rod 102, a screw rod 104 is rotatably installed inside the threaded groove 103, and the screw rod 104 passes through the fixed block 101 and extends to the bottom, a hemostatic compression plate 105 is fixedly installed at the bottom of the screw rod 104, a slide groove 106 is provided on both sides of the screw rod 104, and fixed rods 107 extending to the inside of the slide groove 106 are fixedly installed on both sides of the bottom of the inner wall of the fixed block 101, a display screen 108 is fixedly installed on one side of the top of the transparent hemostatic plate 1, and a speaker 109 is fixedly installed on the rear end of one side of the transparent hemostatic plate 1, and the display screen 108 and the speaker 109 are electrically connected.
[0022] Specifically, by rotating the rotating rod 102, the screw rod 104 is moved downward through the threaded connection inside the thread groove 103. At this time, the fixed rod 107 slides inside the slide groove 106, driving the hemostatic compression plate 105 to steadily apply downward pressure to the bleeding wound. The pressure state of the hemostatic compression plate 105 is conveniently observed through the transparent hemostatic plate 1, so that the screw rod 104 can slowly drive the hemostatic compression plate 105 to apply appropriate pressure to the wound to stop bleeding. The hemostasis is timed and set through the display screen 108. When the hemostasis time is up, an alarm is sounded through the speaker 109, so that the hemostatic pressure on the wound can be released in time, which solves the problem of local tissue damage caused by failure to release the hemostatic pressure on the wound in time.
[0023] Furthermore, the top of the rotating rod 102 passes through the transparent hemostatic plate 1 and extends to the top. A rotating handle 110 is fixedly installed on the top of the rotating rod 102. A knob 111 is rotatably installed on one side of the front end of the transparent hemostatic plate 1, and the knob 111 is electrically connected to the display screen 108.
[0024] Specifically, the rotating rod 102 is conveniently rotated by the rotating handle 110, so that medical staff can more conveniently control the hemostatic pressure force, and conveniently set the hemostatic pressure time by rotating the knob 111;
[0025] Furthermore, a strap hole 112 is opened on both sides of the bottom of the transparent hemostatic plate 1, and a strap body 2 is fixedly installed inside the strap hole 112 on one side. A female Velcro 201 is fixedly installed on the bottom of one side of the strap body 2, and a sub-Velcro 202 is fixedly installed on the top of the other side of the strap body 2.
[0026] Specifically, the strap body 2 passes through the strap hole 112 on one side, and then wraps around the bottom. After the female Velcro 201 and the female Velcro 202 are adhered, the transparent hemostatic plate 1 is fixed on the patient's arm or leg, making it easier for medical staff to operate.
[0027] Furthermore, a groove 114 is formed at the bottom of the hemostatic compression plate 105 , and baffles 115 are fixedly installed on both sides of the groove 114 ;
[0028] Furthermore, a receiving concave plate 113 is fixedly installed on one side of the transparent hemostatic plate 1, and air holes 116 are evenly opened inside the groove 114;
[0029] Specifically, medical staff put the hemostatic cotton coated with disinfectant into the inside of the groove 114, and fix the hemostatic cotton in the inside of the groove 114 through the baffle 115, so that the bleeding at the wound is more comfortable and can be effectively disinfected to avoid wound infection. The compression area is ventilated through the air vent 116 to avoid the wound being in a closed state for a long time, which may cause inflammation of the wound. When the strap body 2 is tied to the arm for hemostasis, the length of the strap body 2 is the same. After the strap body 2 is wrapped around the patient's arm and tied, one end of the excess strap body 2 is folded and placed into the inside of the storage recess 113 for storage.
[0030] Working principle: First, wrap the strap body 2 around the arm or leg so that the transparent hemostatic plate 1 is located on the top of the wound. After the mother Velcro 201 and the child Velcro 202 stick to each other, the transparent hemostatic plate 1 is fixed to the arm or leg. Then, rotate the rotating rod 102 through the rotating handle 110. Since the screw rod 104 is connected to the inside of the thread groove 103 through a thread, the screw rod 104 moves downward inside the thread groove 103. At this time, the ends of the fixing rod 107 that are close to each other slide inside the slide groove 106, making the screw rod 104 move more stably. The screw rod 104 drives the hemostatic compression plate 105 downward to perform hemostatic compression on the wound. The compression state of the wound is observed through the transparent hemostatic plate 1, so that the hemostatic compression plate 105 applies appropriate compression force. Then, set the compression time by turning the knob 111, and display the compression time on the display screen 108. When the compression time is up, an alarm is sounded through the speaker 109, so that medical staff can release the hemostatic compression in time.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
