[0002] The tourniquet is made of medical-grade high-polymer materials, natural rubber, or special rubber. It is long, flat, and highly elastic. It is suitable for single-use in medical institutions for routine treatment and rescue procedures such as intravenous infusion, blood drawing, blood transfusion, and hemostasis; or for emergency hemostasis in cases of limb bleeding or bleeding from snake or insect bites in the wild.

[0003] Bandage hemostasis is a simple and effective method for stopping bleeding in emergency situations involving severe bleeding in the limbs. It achieves hemostasis by compressing blood vessels to block blood flow.

[0004] If a tourniquet is used for an extended period and is not loosened, it may cause ischemia and necrosis of the distal limbs. To avoid adverse events caused by forgetting to loosen the tourniquet, this invention provides a tourniquet that can be opened at set times. Utility Model Content

By placing the pressure plate on the base plate, the movement direction of the timer lock's locking beam is restricted. A push plate is used to relock the opened timer lock. The pressure band can also be manually opened by pressing the elastic cover.

[0020] By altering the movement trajectory of the pressure band with a baffle plate, it also prevents the elastic rod from touching the pressure band when it moves downwards, thus avoiding affecting the normal use of the pressure band. Attached Figure Description

Detailed Implementation

[0027] Example 1:

[0028] Please see Figures 1-5 This utility model provides a technical solution: a pressure band that can be opened at a time, including a timed locking component 1, a tensioning component 2 and a pressure band 3; the tensioning component 2 is fixedly connected to the lower side of the timed locking component 1.

[0029] The tensioning component 2 is a conventional technical means, such as a component for adjusting the tension or loosening of the backpack straps, which will not be described in detail here.

[0030] It also includes a limiting component 41, an elastic component 42, and a housing component 43. The housing component 43 is fixedly connected to the drive end of the timer lock 1. The elastic component 42 is installed in the middle of the housing component 43. The limiting component 41 is inserted into the side of the housing component 43 away from the timer lock 1. The pressure band 3 is fixedly connected to the limiting component 41 and passes through the tensioning component 2.

[0031] The enclosure assembly 43 includes an enclosure 431 and a baffle 432. The enclosure 431 is open on both the left and right sides, and has sliding holes and limiting holes on the top and bottom sides, respectively. The baffle 432 is fixedly connected to the lower side of the enclosure 431 and is located below the sliding holes of the enclosure 431. The middle of the baffle 432 arches downward.

[0032] The elastic component 42 includes an elastic cover 421, an elastic rod 422, a spring 423, and a pair of elastic plates 424. One end of the spring 423 is fixedly connected to the lower end of the inner wall of the housing 431, and the other end of the spring 423 is fixedly connected to the upper end of the inner wall of the elastic cover 421. The sliding holes and limiting holes on the upper and lower sides of the housing 431 correspond to the elastic cover 421 and the elastic rod 422, respectively. The elastic rod 422 is located inside the spring 423. One end of the elastic rod 422 is fixedly connected to the upper end of the inner wall of the elastic cover 421, and the other end passes through the limiting hole. A pair of elastic plates 424 are arranged along the length of the housing 431, symmetrically distributed on both sides of the bottom of the elastic cover 421, and fixedly connected to the bottom of the elastic cover 421.

[0033] When the spring 423 is in its natural state, the elastic cover 421 and the elastic rod 422 protrude upwards from the outer wall of the housing 431; and there is a distance between the elastic cover 421 and the bottom of the housing 431, leaving space for the elastic cover 421 to move downwards. The side of the elastic cover 421 located inside the housing 431 and close to the timing lock 1 is hollowed out to reduce weight, optimize the spatial structure, and reduce the pressure on the spring 423.

[0034] The elastic plate 424 includes a base plate 51 and a pair of locking blocks 52. The base plate 51 is fixedly connected to the outer wall of the bottom of the elastic cover 421. The pair of locking blocks 52 are fixedly connected to the upper side of the base plate 51, and the sides of the pair of locking blocks 52 near both ends of the base plate 51 are arc-shaped. The locking block 52 near the timing lock 1 is at a distance from the end of the base plate 51.

[0035] The timer lock 1 includes a timer lock 11, a push plate 13, and a pair of clamping plates 14. The timer lock 11 can be manually set to a time, such as 3 minutes or other times. The lower side of the timer lock 11 is fixedly connected to the tensioning assembly 2. The push plate 13 is fixedly connected to the upper side of the lock beam of the timer lock 11. The housing 431 has a push hole on the upper side of the push plate 13, allowing the push plate 13 to move left and right within the push hole. The push plate 13 protrudes upward from the push hole. A pair of clamping plates 14 are fixedly connected to the side of the lock beam of the timer lock 11 near the elastic block 52. The clamping plates 14 correspond to the locking block 52 and extend to the upper side of the base plate 51, with arc-shaped ends.

[0036] The limiting assembly 41 includes a limiting cover 411 and a pair of snap fasteners 412. The limiting cover 411 is inserted into the housing 431. The outer wall of the limiting cover 411 is fixedly connected to the end of the pressure band 3. The snap fasteners 412 have an "L" shaped cross-section, with one end fixedly connected to the limiting cover 411 and the other end facing downwards. The downward-facing end of the snap fasteners 412 is arc-shaped. A pair of snap fasteners 412 corresponds to a pair of locking blocks 52, and the downward-facing end of the snap fasteners 412 is located on the upper side of the base plate 51.

[0037] Working principle: The operator first sets the automatic unlocking time of the timer lock 11, generally 3 minutes. Then, the application is placed on the area where the patient needs hemostasis. The limiting cap 411 is inserted into the housing 431. At the same time, as the locking buckle 412 moves towards the locking block 52, the lower end of the locking buckle 412 forces the locking block 52 and the base plate 51 to move downward, thereby compressing the spring 423 and causing the elastic cap 421 and elastic rod 422 to move downward. When the elastic rod 422 moves downward, it moves within the space enclosed by the baffle plate 432 and the housing 431, thus preventing the elastic rod 422 from touching the tourniquet 3. When the lower end of the locking buckle 412 moves beyond the highest point of the locking block 52, the spring 423 drives the elastic cap 421, elastic rod 422, base plate 51, and elastic block 52 to move upward, thereby completing the locking. Then, the staff pulls the pressure band 3 outward from the end of the pressure band 3 away from the limiting cover 411, gradually tightening the hemostatic site on the patient.

[0038] Unlocking can be done manually or automatically.

[0039] Manual unlocking: The operator presses the elastic cover 421 towards the baffle 432, compressing the spring 423, which in turn moves the elastic cover 421, elastic rod 422, base plate 51, and elastic block 52 downwards. When the locking block 52 moves to the point where it disengages from the locking buckle 412, under the elastic action of the pressure belt 3, the limiting cover 411 drives the locking buckle 412 to disengage from the box body 431, thus completing the unlocking.

[0040] Automatic unlocking: When the set time expires, since the pressure plate 14 is located on the upper side of the base plate 51, the locking beam of the timer lock 11 will drive the pressure plate 14 to move towards the locking block 52, thereby forcing the spring 423 to be compressed. The elastic cover 421, elastic rod 422, base plate 51, and elastic block 52 will move downward. When the locking block 52 moves to the point where it disengages from the locking buckle 412, under the elastic action of the pressure band 3, the limit cover 411 will drive the locking buckle 412 to disengage from the housing 431, thus completing the automatic unlocking.

[0041] Then the staff pulls the push plate 13 away from the elastic cover 421, so that the timer lock 11 is locked again for easy use next time.
