Description

Technical Field

[0001] The automatic tensioning and fixing device for abdominal trauma hemostatic belt of the present invention relates to an automatic tensioning and fixing device for precisely regulating pressure to stop bleeding from a wound, belonging to the technical field of first aid tools, and particularly relates to an automatic tensioning and fixing device that ensures the device is firmly fixed to adapt to the patient's breathing and body movements through a fixing component, and precisely regulates the pressure of the hemostatic belt through an adjusting component to achieve effective hemostasis and ensure the safety of the patient. Background Art

[0002] There are many deficiencies in the existing abdominal trauma hemostatic devices on the market at present, which limit their effectiveness and scope of application in actual use. Firstly, there are serious defects in the adaptability of the existing hemostatic devices. Most devices have fixed sizes or limited adjustment ranges, and it is difficult to flexibly adjust according to the patient's body shape, abdominal size, and wound location. For patients with different body shapes, whether obese patients or patients with a small body size, the fixed-size hemostatic devices either cannot fit tightly, resulting in poor hemostatic effects, or are overly tight, causing great pain to the patients. Secondly, in terms of stability and comfort, many hemostatic devices lack effective fixing structures when fixed, and it is difficult to ensure firm fixation on the patient's abdomen. During the patient's breathing and body movements, the device is prone to displacement and loosening, which not only affects the hemostatic effect but may also cause secondary damage to the wound. Moreover, the existing devices often neglect the patient's wearing experience during design, and the material and structure design are unreasonable. Wearing for a long time will make the patient feel uncomfortable and reduce the patient's cooperation. At the same time, the existing devices generally lack the function of real-time monitoring of the pressure of the hemostatic belt and the local tissue temperature, and cannot precisely regulate the pressure of the hemostatic belt. Too little pressure cannot effectively stop bleeding, and too much pressure may lead to serious consequences such as tissue ischemia and necrosis, threatening the patient's life safety.

[0003] Publication number CN118662185A discloses an abdominal compression hemostatic belt, including an abdominal belt. A tightening device is provided on the abdominal belt. The tightening device uses a tightening belt, and a magic tape is provided on the tightening belt; a pressurizing device is provided on the inner wall of the abdominal belt. The pressurizing device includes several air bags arranged at intervals. A gas shunt structure is provided on the outer surface of the abdominal belt. All the air bags are connected to an inflation device through the gas shunt structure. The gas shunt structure can connect all the air bags or connect a single air bag alone. In the present invention, a magic tape is provided on the tightening belt, which can quickly fix the abdominal belt on the patient's abdomen; when the inflation device is used to connect a single air bag alone through the gas shunt structure, a single air bag is inflated to locally compress the wound, and the pressurized air bag area can be selected according to the position of the wound; when the abdominal bleeding is large, the inflation device is used to connect all the air bags through the gas shunt structure, and all the air bags can be inflated simultaneously to achieve the effect of overall compression of the abdomen. The above-mentioned hemostatic belt is difficult to be flexibly adjusted according to the patient's body type, abdominal size and wound position. For patients with different body types, whether they are obese patients or thin patients, the hemostatic device with a fixed size either cannot fit tightly, resulting in poor hemostatic effect, or is overly tightened, bringing great pain to the patient. Summary of the Invention

[0004] In order to improve the above situation, the automatic tensioning and fixing device for an abdominal trauma hemostatic belt of the present invention provides an automatic tensioning and fixing device that ensures the stable fixation of the device to adapt to the patient's breathing and body movements through a fixing component, and precisely regulates the pressure of the hemostatic belt through an adjusting component to achieve effective hemostasis and ensure the safety of the patient.

There are two spinning discs (14), and the two spinning discs (14) are respectively placed near both ends of the tourniquet (4). Preferably, the corresponding parts of the tourniquet (4) and the spinning disc (14) are made of rigid PVC. A cross-shaped slide rail (21) is opened on the top surface of the spinning disc (14). The cross-shaped slide rail (21) is in a cross-shaped structure. The cross-shaped slide rail (21) is composed of a horizontal groove and a vertical groove vertically intersecting in the middle. The fixed connection bracket (19) is of a U-shaped structure. The fixed connection bracket (19) is composed of two horizontal bars and one vertical bar.

The distance from the center axis of the spinning disc (14) to the fixed connection bracket (19) in the length direction of the tourniquet (4) is approximately half of the radius of the spinning disc (14). The motor (17) is fixedly placed above the other horizontal bar of the fixed connection bracket (19). The motor shaft of the motor (17) passes through the other horizontal bar of the fixed connection bracket (19), and a support bearing is arranged between the motor shaft and the other horizontal bar of the fixed connection bracket (19). The middle part of the top surface of the connecting rod (20) is fixedly connected to the motor shaft of the motor (17).

And the length of the first slider (16) in the vertical groove direction is greater than the width of the horizontal groove of the cross-shaped slide rail (21). The other end of the connecting rod (20) is rotatably connected to the second slider (18). The second slider (18) is slidably connected to the spinning disc (14) through the horizontal groove of the cross-shaped slide rail (21). And the length of the second slider (18) in the horizontal groove direction is greater than the width of the vertical groove of the cross-shaped slide rail (21). Each spinning disc (14) corresponds to two pressure belts (15). The two pressure belts (15) are placed on both sides of the spinning disc (14) in the length direction of the tourniquet (4). The pressure belts (15) are fixedly connected to the side surface of the spinning disc (14). The other end of the pressure belt (15) is fixedly connected to one side surface of the tourniquet (4). A spiral groove (8) is formed on the other side surface of the tourniquet (4). The spiral groove (8) is arranged in a wavy long strip structure along the direction of the tourniquet (4). There are multiple groups of the spiral grooves (8). The multiple groups of spiral grooves (8) are arranged at equal intervals along the length direction of the tourniquet (4). There are two spiral grooves (8) in each group. The two spiral grooves (8) in each group are symmetrically arranged with respect to the tourniquet (4). An integrated sensor (5) is arranged on the tourniquet (4). The integrated sensor (5) is placed between the two spinning discs (14). Preferably, the integrated sensor (5) is internally provided with a pressure sensor and a temperature sensor. The pressure sensor real-time feeds back the pressure applied by the tourniquet (4). The temperature sensor is used to monitor the temperature change of the local tissue to avoid tissue ischemia or necrosis caused by excessive tension. During use, according to the patient's body type, carefully adjust the positions of the upper fixing frame (1), the lower fixing frame (6), and the adjustment buckle (2) at the other end of the tourniquet (4). Connect the adjustment buckles (2) at both ends of the upper fixing frame (1) through snap fasteners to form an annular structure, and wind it around a suitable position above the patient's abdomen. Ensure that the silicone buffer layer on the inner side of the upper fixing frame (1) is in close contact with the patient's skin to provide comfort and protection. Similarly, connect the adjustment buckles (2) at both ends of the lower fixing frame (6) by snap fasteners to form an annular shape, place it at the corresponding position below the patient's abdomen, and cooperate with the upper fixing frame (1) to jointly stabilize the fixing device. Then, connect the adjustment buckle (2) at one end of the tourniquet (4) to the adjustment buckle (2) at the other end through a snap fastener to make it annular, and wind the tourniquet (4) around the wound position to ensure that the wound is located in the central area of the tourniquet (4). After the device is worn, the integrated sensor (5) starts to detect the pressure applied by the tourniquet (4) in real time. At this time, observe the pressure data feedback by the integrated sensor (5). If the pressure is small and insufficient to effectively stop bleeding, start the adjustment component. Drive the connecting rod (20) to rotate through the motor (17). When the connecting rod (20) rotates, the first slider (16) slides in the vertical groove of the cross-shaped slide rail (21), and the second slider (18) slides in the horizontal groove of the cross-shaped slide rail (21), thereby driving the swaging disc (14) to rotate, and then tightening the pressure belts (15) on both sides of the swaging disc (14) to perform a tightening operation on the tourniquet (4) to increase the pressure of the tourniquet (4) on the wound and achieve the purpose of effective hemostasis. During the hemostasis process, the integrated sensor (5) continuously detects the pressure applied by the tourniquet (4) in real time. Since the patient's physical condition and wound condition may change, it is necessary to adjust the pressure of the tourniquet (4) according to the actual situation. When the integrated sensor (5) detects that the pressure is large, it may cause adverse effects on the patient's tissue. At this time, drive the connecting rod (20) to rotate in the opposite direction through the motor (17), thereby driving the swaging disc (14) to rotate in the opposite direction, and then relaxing the pulling of the pressure belt (15) on the tourniquet (4) to reduce the pressure of the tourniquet (4) on the wound and avoid tissue ischemia or necrosis caused by excessive tension. At the same time, the temperature sensor built in the integrated sensor (5) is used to monitor the temperature change of the local tissue. If the temperature shows abnormal changes, it can also be used as a reference basis for adjusting the pressure of the tourniquet (4). When the patient's wound has been effectively treated and the tourniquet is no longer needed, carefully untie the snap fastener connections of the adjustment buckles (2) at both ends of the upper fixing frame (1), the lower fixing frame (6), and the tourniquet (4), and slowly remove the device from the patient's abdomen. During the removal process, pay attention to avoiding secondary injury to the patient's wound; Embodiment 2

[0013] The difference between this embodiment and Embodiment 1 is that: the square-port extended bandage (13) is replaced with an angled-port extended bandage (22). The width of the angled-port extended bandage (22) gradually decreases at one end that is not connected to the tourniquet (4). When in use, when passing through the adjustment buckle (2), the square-port extended bandage (13) can pass through more smoothly and conveniently, enabling medical staff to complete the fixation operation of the tourniquet more quickly during emergency treatment, saving precious treatment time; Embodiment 3

[0014] The difference between this embodiment and Embodiment 1 is that: a hook-and-loop female end (24) is fixedly arranged on each of the two relatively wide side surfaces of the square-port extended bandage (13). On one side of the tourniquet (4), and between the rotary pressing disc (14) near the other end and the second connection buckle (10) closest to the rotary pressing disc (14), a hook-and-loop male end (23) is fixedly arranged. When in use, the other end of the square-port extended bandage (13) is pasted to the hook-and-loop male end (23) through the hook-and-loop female end (24), which can effectively prevent the square-port extended bandage (13) from accidentally touching the rotary pressing disc (14) and other structures above the rotary pressing disc (14) during subsequent operations or the patient's activities, thus ensuring the normal and stable operation of the adjustment assembly, and preventing the accurate adjustment of the tourniquet pressure from being affected by the interference of the bandage, and ensuring the smooth progress of the entire hemostasis process and the hemostasis effect; Both the upper fixing frame (1) and the lower fixing frame (6) adopt a strip-shaped structure, and the two ends can be snap-connected into a circular ring through the adjustment buckle (2). Both the upper fixing frame (1) and the lower fixing frame (6) are made of titanium alloy material, with electro-polishing treatment on the surface and coated with a nano antibacterial coating, and a silica gel buffer layer is arranged on the inner side, with a thickness of 2 - 3 mm. It can be flexibly adjusted according to different sizes of the patient's abdomen, with strong adaptability, ensuring that the device is stably fixed on the patient's abdomen. Made of titanium alloy material, it has the characteristics of high strength and light weight, can withstand a certain amount of external force and will not cause too much burden on the patient. The electro-polishing treatment on the surface and the coated nano antibacterial coating are not only beautiful but also can effectively prevent the growth of bacteria and reduce the risk of wound infection. The silica gel buffer layer on the inner side has a thickness of 2 - 3 mm, which can increase the comfort of contact with the patient's skin and avoid discomfort or damage caused by the direct contact of the metal frame with the skin; The design that the upper fixing frame (1) and the lower fixing frame (6) are respectively fixedly connected to one end of the extended strap (3) and seamlessly joined further enhances the adjustability of the fixing assembly, can adapt to a wider range of patient body types, and makes the entire fixing device more stable; The top surface of the spinning disc (14) is provided with a cross-shaped slide rail (21). The cross-shaped slide rail (21) has a cross-shaped structure. The cross-shaped slide rail (21) is designed to be composed of a horizontal groove and a vertical groove that vertically intersect in the middle. Cooperating with the first slider (16) and the second slider (18), when the motor (17) drives the connecting rod (20) to rotate, the precise rotation of the spinning disc (14) can be realized, so as to effectively control the tightening or relaxation of the pressure belt (15) on the tourniquet (4), and the accuracy of adjusting the pressure of the tourniquet (4) is high; Each spinning disc (14) corresponds to two pressure belts (15). The two pressure belts (15) are arranged on both sides of the spinning disc (14) in the length direction of the tourniquet (4). When the spinning disc rotates, the pressure belt (15) can evenly apply a pulling force or a relaxing force to the tourniquet (4), ensuring uniform pressure distribution of the tourniquet (4) and improving the hemostatic effect; Another side of the tourniquet (4) is provided with a spiral groove (8). The spiral groove (8) is arranged in a wavy long strip structure along the direction of the tourniquet (4). There are multiple groups of the spiral grooves (8). The design that the multiple groups of spiral grooves (8) are arranged at equal intervals along the length direction of the tourniquet (4) increases the flexibility and deformability of the tourniquet (4). During the process of adjusting the pressure, it can better adapt to different pressure changes and the physical conditions of patients, and further improve the hemostatic effect and the comfort of patients; An integrated sensor (5) is arranged on the tourniquet (4). The integrated sensor (5) is designed with a pressure sensor and a temperature sensor built in. The pressure sensor can real-time feedback the pressure applied by the tourniquet (4), providing accurate data support for the adjustment component to ensure that the pressure of the tourniquet (4) is always within the appropriate range for effective hemostasis. The temperature sensor monitors the local tissue temperature change, and can timely detect the risk of tissue ischemia or necrosis caused by excessive tension, providing an important reference basis for adjusting the pressure of the tourniquet (4) and ensuring the safety and health of patients.
