[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Example

[0032] like Figures 1 to 10 As shown, the flip-and-press hemostatic device of this embodiment includes a tourniquet main body 1, a tensioning belt 2, and a flip-and-press multi-stage locking structure 3. One end of the tensioning belt 2 is connected to one end of the tourniquet main body 1, and the flip-and-press multi-stage locking structure 3 is installed on the outside of the other end of the tourniquet main body 1. The other end of the tourniquet main body 1 is provided with a belt body anti-pinch traction structure 6. The other end of the tensioning belt 2 passes through the belt body anti-pinch traction structure 6 and is connected to the flip-and-press multi-stage locking structure 3. The flip-and-press multi-stage locking structure 3 is used to adjust the tensioning degree of the tensioning belt 2 and lock the tensioning belt 2 after adjustment.

[0033] During use of the flip-press hemostatic device of this embodiment, the tourniquet body 1 and the tensioning belt 2 are put together on the injured limb, and the other end of the tensioning belt 2 is passed through the belt body anti-clamping traction structure 6, and then the length of the tensioning belt 2 is adjusted through the flip-pressing multi-stage locking structure 3, and the tensioning belt 2 is also stretched to apply pressure to the limb, and after adjustment, it is locked. The overall structural design is reasonable, and the tensioning belt is stretched through the flip-pressing operation to adjust the hemostatic pressure of the tourniquet body. Compared with the existing rotary hemostatic method, the operation process is simplified.

[0034] In this embodiment, one end of the tourniquet body 1 is provided with a belt loop for passing one end of the tension belt 2. The design of the belt loop facilitates the connection between the tension belt 2 and the tourniquet body 1. More specifically, one end of the tension belt 2 passes through the belt loop and is connected and fixed to the body.

[0035] As a preferred embodiment, the belt body anti-pinch traction structure 6 includes a square hole opened at one end of the tourniquet main body 1 and two anti-stuck stick shafts 61. The two anti-stuck stick shafts 61 are respectively arranged on the outside of the square hole and are distributed in parallel and spaced apart. The two ends of the anti-stuck stick shafts 61 are respectively rotatably connected to the outside of one end of the tourniquet main body 1. The tensioning belt 2 bypasses one of the anti-stuck stick shafts 61 from the outside, passes through the square hole and then bypasses the other anti-stuck stick shaft 61.

[0036] In the above embodiment, after the tension belt 2 passes through the square hole and bypasses the two anti-jamming rod shafts 61, the tension belt 2 can move along the anti-jamming rod shafts 61, changing the sliding friction into rolling friction to avoid sliding jamming.

[0037] In this embodiment, one end of the tourniquet body 1 is tilted outward (position a in the figure), which prevents the tensioning belt 2 and the tourniquet body 1 from closely fitting the skin during the tightening process, compressing the skin between the two and causing skin damage.

[0038] As a preferred embodiment, the above-mentioned flip-pressing multi-stage locking structure 3 includes a three-section folding component, and the above-mentioned three-section folding component includes a first section plate 31, a second section plate 32 and a third section plate 33. A hinge seat is provided in the middle part of the outer side of the above-mentioned tourniquet body 1, one end of the above-mentioned first section plate 31 is hinged to the above-mentioned hinge seat through a first rotating pin, the above-mentioned second section plate 32 is hinged to the other end of the above-mentioned first section plate 31 through a second rotating pin, and one end of the above-mentioned three-section plate 33 is hinged to the other end of the above-mentioned second section plate 32 through a third rotating pin. A primary locking structure 34 is provided on the outer side of the other end of the above-mentioned tourniquet body 1, and the above-mentioned first section plate 31 is used to rotate and fit to the outer side of the above-mentioned tourniquet body 1 under the action of external force, and lock with the above-mentioned primary locking structure 34 Tighten, or unlock under the action of external force; the above-mentioned first section plate 31 is provided with a belt length adjustment and self-locking structure 311 for the other end of the above-mentioned tensioning belt 2 to pass through and self-lock; the above-mentioned second section plate 32 is used to be pressed and rotated under the action of external force until it is in contact with the side end of the above-mentioned first section plate 31; the above-mentioned third section plate 33 is used to be rotated under the action of external force to be in contact with the side of the above-mentioned second section plate 32 close to the first section plate 31, and to press the other end of the above-mentioned tensioning belt 2; the other end of the above-mentioned tourniquet main body 1 is provided with a secondary locking structure 35 on the outside, and the above-mentioned secondary locking structure 35 is used to lock the other end of the first section plate 31 that is in contact with the outside of the above-mentioned tourniquet main body 1, as well as the second section plate 32 that is in contact with the side end of the above-mentioned first section plate 31 and the third section plate 33 that is in contact with one side of the above-mentioned second section plate 32.

[0039] In the above-mentioned implementation scheme, the first plate body 31 and the second plate body 32, and the second plate body 32 and the third plate body 33 are all one-way hinged. When in use, after the tensioning belt 2 passes through the belt body anti-pinch traction structure 6, it is further connected with the belt body length adjustment and self-locking structure 311 on the first plate body 31. After the tensioning belt 2 and the tourniquet main body 1 are put on the injured limb part, the length of the tensioning belt 2 is adjusted by the belt body length adjustment and self-locking structure 311 to make it tightly bound to the injured limb, and then locked. Next, press the first plate body 31 to make it rotate and fit the outside of the tourniquet main body 1, and then lock the first plate body 31 through the primary locking structure 34. In this process, the first plate body 31 will be pulled by the tensioning belt 2, thereby prompting the tourniquet main body to 1 applies pressure to the limb to stop bleeding. Next, operate the three-section plate 33 to press and rotate until it fits on the side end of the second section plate 32. Then press the second section plate 32 to rotate and fit on the outside of the first section plate 31, so that the three-section plate 33 presses the tension belt 2 drawn from the outside of the first section plate 31. Next, operate the secondary locking structure 35 to lock the folded first section plate 31, the second section plate 32 and the third section plate 33, so that the tourniquet body 1 continues to apply pressure. The operation is completed. During the whole process, the length of the tension belt 2 can be adjusted by one hand at the belt length adjustment and self-locking structure 311, and the flipping and folding of the first section plate 31, the second section plate 32 and the third section plate 33 and the locking of the primary locking structure 34 and the secondary locking structure 35 can be operated by one hand. After the three-section folding assembly is folded, its length is only about one-third of that after it is unfolded.

[0040] In this embodiment, by reasonably setting the length of the first plate 31, the second plate 32, and the third plate 33, the single-handed force F≤60N for the upper limbs and the double-handed force F≤200N for the lower limbs during compression are met, and adult women can easily complete the operation, and the difficulty of operation is much lower than that of the traditional rotary tourniquet. In addition, the size of the tensioning belt 2 for upper and lower limb hemostasis, the pre-locking pressure, the tightening length, the "lever" effort saving multiple formed during the flipping of the first plate 31, the second plate 32, and the third plate 33 are all determined through batch experiments by relevant personnel, so that the parameters of the entire hemostatic device are more in line with the actual needs of the user population.

[0041] As a preferred embodiment, the above-mentioned primary locking structure 34 includes two elastic blocks, and the two elastic blocks are respectively installed on both sides of the other end of the above-mentioned tourniquet body 1. The above-mentioned section of plate 31 is used to rotate and fit to the outside of the above-mentioned tourniquet body 1 under the action of external force, and make its two sides squeeze in and clamp between the two elastic blocks.

[0042] In the above-described embodiments, when pressing the one-section plate body 31 to turn it over and fold it to fit against the outer side of the tourniquet main body 1, both sides of the one-section plate body 31 will be squeezed into the space between the two elastic blocks, so that both sides of the one-section plate body 31 will automatically engage with the two elastic blocks after being turned over and fitted, realizing primary locking, and the operation is relatively convenient.

[0043] As a preferred embodiment, the above-described secondary locking structure 35 includes a locking ring 351 and a lock seat 352. The lock seat 352 is fixed to the outer end of the other end of the tourniquet main body 1. A chute 353 is provided in the lock seat 352. The chute 353 penetrates both sides of the lock seat 352. A part of the locking ring 351 passes through the chute 353, and the remaining part is located outside the tourniquet main body 1. The locking ring 351 can move along the chute 353 to be tightened and sleeved outside the other end of the one-section plate body 31 and one end of the two-section plate body 32, or move to be separated from the one-section plate body 31.

[0044] In the above-described embodiments, after the two-section plate body 32 and the three-section plate body 33 are folded, by translating the locking ring 351, the locking ring 351 can be sleeved outside one end of the one-section plate body 31, the two-section plate body 32, and the three-section plate body 33 after folding, so that it can stably maintain the folded state, that is, maintain the continuous state of the tourniquet main body 1 pressing on the limb. The operation is very fast and convenient.

[0045] In this embodiment, the other end of the tensioning belt 2 is provided with a magic tape and can be adhered to itself through the magic tape. After the three-section folding assembly is locked by the secondary locking structure 35 to achieve continuous pressurization, the other end of the tensioning belt 2 can be adhered to itself through the magic tape to perform a final "locking" to a certain extent, avoiding the length of the end of the tensioning belt 2 being affected by the outside world and changing.

[0046] As a preferred embodiment, the above-described belt length adjustment and self-locking structure 311 is a "mesh" - shaped belt - passing groove opened on the one-section plate body 31.

[0047] In the above-described embodiments, the design of the belt - passing groove is similar to the conventional mesh buckle structure on the market. The other end of the tensioning belt 2 can achieve self - locking after passing through and around the wearing groove. At the same time, the length of the tensioning belt 2 can be flexibly adjusted after passing through and winding, and the design is relatively reasonable and ingenious.

[0048] As a preferred embodiment, a main unit 5 is provided on the entire flip - press type hemostatic device. The main unit 5 is provided with a display screen and control buttons. The main unit 5 is installed on the side of the two-section plate body 32 facing away from the one-section plate body 31. The main unit 5 is provided with a timing module and an alarm module.

[0049] In the above-mentioned implementation scheme, the host 5 can be a computer host of a suitable model on the market (chip type), and the host 5 is equipped with a display screen and a control button, and an integrated timing module and an alarm module. When the device is used for hemostasis and pressurization, the timing module and the alarm module can be used to set the monitoring time of hemostasis, such as hemostasis and pressurization for 2 hours. After that, the alarm module alarms, thereby effectively reminding the wearer or medical staff to remind the wounded to reach the maximum hemostasis time, and the tourniquet needs to be loosened to avoid excessive pressurization and hemostasis causing tissue necrosis due to poor blood flow in the wound part, and timely "decompression" is carried out to ensure that blood recirculation, and then hemostasis and pressurization can be continued as appropriate. Among them, the alarm module includes a conventional vibration module and a buzzer module, which are all hardware products and software products of the prior art. Especially when the product is needed to be used in the field (military training and other occasions), it can be effectively and scientifically stopped by setting the duration of hemostasis and pressurization, and then the wearer and medical staff are reminded to avoid the serious consequences caused by the long pressurization time. This design has great significance.

The host 5 is provided with a communication module, which can be connected to the background control terminal network.

[0051] In the above implementation scheme, the monitoring module can be a pressure sensor, a blood oxygen sensor, a heart rate sensor, a temperature sensor, and other existing sensors for monitoring physiological indicators, which can be flexibly expanded according to actual needs. The functional module 4 is designed to be arc-shaped in contact with the skin, and is made of rubber material (sensor embedded), which will not cause damage to the skin or wound surface under high pressure. At the same time, the entire tourniquet surface is treated with antibacterial and antibacterial treatment to reduce the risk of infection of the wounded. Functional module 4 is designed to be dustproof and waterproof. The entire functional module 4 of general application scenarios meets the IP67 protection level. For special application scenarios such as underwater combat, it can be upgraded to meet IP68, and can be equipped for combat personnel according to actual needs. The host 5 is equipped with a GPS module and has a GPS positioning function. It can encrypt and synchronize the personnel position to the command center, emergency center, etc. in real time, which is convenient for the center to understand the personnel position information. At the same time, it has an emergency rescue signal sending function. In an emergency, it can send an encrypted distress signal to the command center and the emergency center, and the center will make rescue arrangements based on the position of the wounded.
