Description

Technical Field

[0001] The invention relates to the technical field of tourniquets, in particular to a femoral artery pressurized tourniquet. Background Art

[0002] The femoral artery pressure tourniquet is a medical auxiliary device, which is mainly used to quickly and effectively control femoral artery bleeding in emergency situations. The femoral artery pressure tourniquet is usually composed of a supporting structure, a compression pad and a fixing device. The supporting structure is used to maintain the stability and position of the tourniquet, the compression pad directly acts on the bleeding site to apply pressure, and the fixing device ensures that the tourniquet can be firmly fixed on the patient.

[0003] After searching, the Chinese patent with the announcement number CN211325350U discloses a pressurized tourniquet for surgery, including a tourniquet body, the tourniquet body is constructed as a narrow and long belt-shaped structure, a first connecting structure and a second connecting structure are respectively arranged at both ends of the tourniquet body, the first connecting structure and the second connecting structure are detachably connected when the tourniquet body is in a winding state, a pressurized airbag is arranged on the tourniquet body, the pressurized airbag is constructed as a tubular structure extending along the length direction of the tourniquet body, a plurality of pressurized airbags are arranged in parallel with each other, and an inflation part is also included, the inflation part is connected with the plurality of pressurized airbags through a pipeline, and air can be inflated into the plurality of pressurized airbags at the same time. The above scheme is used to stop bleeding at the wound during surgery, but the above scheme still has the following shortcomings when actually used: When the pressurized tourniquet proposed in the above scheme is used, the medical staff inflates the pressurized airbag by continuously kneading the inflatable part to expand the pressurized airbag. For the inflatable part, the air intake and air output are constant. If the air intake and air output of the inflatable part are small when kneaded once, the medical staff needs to knead the inflatable part frequently and at a high frequency to complete the inflation process, which not only reduces the inflation efficiency, but also causes soreness in the hand muscles of the medical staff due to long-term operation, increases the difficulty of operation and the workload of the medical staff. When the inflatable part is kneaded once, if The large air intake and exhaust volumes can quickly inflate the pressurized airbag, but due to the large single air intake volume, it is difficult for medical staff to accurately control the pressure applied by the pressurized airbag on the wound site, which may cause excessive pressure on the wound, increase the patient's pain, and may even cause further damage to the wound. Since the pressure applied by the pressurized airbag is not easy to control accurately, medical staff need to constantly observe and adjust during the operation to ensure that the pressure is moderate, which not only increases the complexity of the operation, but may also increase risks due to improper operation, such as excessive pressure leading to obstructed blood circulation.

[0016] Beneficial effects of the present invention: 1. This femoral artery pressurized tourniquet is provided with an air volume regulating structure. In the initial stage of inflation, the air inlet pipe is adjusted to the maximum air volume through the air volume regulating structure, so that the pressurized bag can be quickly inflated and expanded. When the pressurized bag fits the patient's wound position, the air volume is reduced through the regulating structure to achieve slow expansion. This design not only ensures the rapid response of the pressurized bag, but also facilitates the staff to accurately adjust the pressure applied to the patient's wound, avoiding the discomfort caused to the patient by sudden pressure changes. Accurate pressure adjustment helps to reduce the possible damage to the patient due to improper pressurization. Through the air volume regulating structure, the staff can monitor and adjust the pressure of the pressurized bag in real time to ensure the safety of the patient during treatment. 2. This femoral artery pressurized tourniquet, by setting a sliding frame, the design allows medical personnel to flexibly adjust the position of the pressurized bag according to the specific position of the patient's wound, which greatly enhances the adaptability of pressurized treatment, ensures that the pressurized bag can accurately cover the wound, and improves the treatment effect. The sliding frame can be easily unlocked by pulling the pressure button, so that it can slide freely on the first tourniquet. After the adjustment is completed, the position of the pressurized bag can be fixed by pressing the pressure button again. This operation method is simple and fast, which reduces the difficulty of operation for medical personnel. This design simplifies the adjustment process of the position of the pressurized bag, so that medical personnel can complete pressurized treatment more quickly and accurately; 3. The femoral artery pressurized tourniquet is provided with an elastic compression member. Through simple operation steps, the staff can easily store the pressurized tourniquet. First, the outer cylinder is removed, and then the first tourniquet and the second tourniquet are wound around the fixing frame and the elastic rod. Finally, the outer cylinder is connected to complete the storage. This design greatly simplifies the storage process and improves work efficiency. When the first tourniquet and the second tourniquet are wound around the elastic rod, they will squeeze the elastic rod. Since the elastic rod is connected to the fixing frame through two tension springs, the elastic force of the tension springs enables the elastic rod to compress the tourniquet in the wound state, thereby achieving a compression and fixing effect. This design effectively avoids the loosening of the rolled tourniquet and improves the stability after storage. 4. This type of femoral artery pressurized tourniquet, by setting a damping ring, the large friction between the damping ring and the air inlet pipe effectively prevents the accidental movement of the adjustment sleeve in the non-operating state, which ensures that the pressure setting of the pressurized bag will not change due to external factors (such as vibration, collision, etc.), thereby ensuring the continuity and stability of the treatment process.

[0022] like Figures 1 to 9 As shown, the femoral artery pressurized tourniquet includes a connecting buckle 1; a first tourniquet 2, one end of which is connected to the connecting buckle 1; a second tourniquet 3, one end of which is connected to the connecting buckle 1; a fixing frame 4, fixed to the end of the first tourniquet 2 away from the connecting buckle 1, the fixing frame 4 is composed of two opposite side plates and a cross bar, the cross bar is fixed between the two side plates, and the cross bar is connected to the end of the first tourniquet 2 away from the connecting buckle 1; two card slots 5 are both opened on the fixing frame 4, and the two card slots 5 are arranged opposite to each other; like Figure 4 , Figure 5 As shown, the femoral artery pressurized tourniquet also includes an elastic clamping member, which is arranged on the fixing frame 4, and the elastic clamping member includes: two slideways 61, both of which are opened on the fixing frame 4, and the two slideways 61 are arranged opposite to each other; an elastic rod 62, which is placed between the two slideways 61, and the two ends of the elastic rod 62 extend into the two slideways 61 respectively, and the elastic rod 62 is slidably arranged in the two slideways 61; two limiting rings 63, which are respectively fixedly sleeved on the two ends of the elastic rod 62, and the two limiting rings 63 are respectively located on both sides of the fixing frame 4, and the side surfaces of the two limiting rings 63 are mutually fitted with the side surfaces of the fixing frame 4; two tension springs 64, one end of which is connected to the fixing frame 4, and the other end is respectively connected to the two ends of the elastic rod 62; When the femoral artery pressurized tourniquet proposed by the present invention is in use and needs to be stored, the staff first removes the outer cylinder 71 from the fixing frame 4, and then winds the first tourniquet 2 and the second tourniquet 3 around the fixing frame 4 and the elastic rod 62, so that the first tourniquet 2 and the second tourniquet 3 are wound into a roll, and finally the outer cylinder 71 at the end of the second tourniquet 3 is connected to the fixing frame 4, so that the pressurized tourniquet can be stored, which is convenient for medical staff to store and transfer the pressurized tourniquet. When the first tourniquet 2 and the second tourniquet 3 are wound around the elastic rod 62, the first tourniquet 2 and the second tourniquet 3 will squeeze the elastic rod 62, and the elastic rod 62 is connected to the fixing frame 4 through two tension springs 64. Under the elastic force of the two tension springs 64, the elastic rod 62 can press the first tourniquet 2 and the second tourniquet 3 in the wound state, thereby pressing and fixing the first tourniquet 2 and the second tourniquet 3, and preventing the rolled first tourniquet 2 and the second tourniquet 3 from loosening; like Figure 5 , Figure 6 As shown, the femoral artery pressurized tourniquet also includes a connecting structure, which is arranged at the end of the second tourniquet 3 away from the connecting buckle 1, and the connecting structure includes: an outer cylinder 71, which is fixed to the end of the second tourniquet 3 away from the connecting buckle 1, and both ends of the outer cylinder 71 are open structures; two clamping blocks 72, which are respectively slidably arranged at the two ends of the outer cylinder 71; a spring 73, and the two ends of the spring 73 are respectively connected to the two clamping blocks 72; two sliding openings 74, which are respectively opened at the two ends of the outer cylinder 71; two sliding blocks 75, which are respectively fixed on the two clamping blocks 72, and the two sliding blocks 75 are respectively slidably arranged in the two sliding openings 74; When the two locking assemblies 77 are in the closed position, the two locking assemblies 77 are in the closed position, and the two locking assemblies 77 are in the closed position, so that the two locking assemblies 77 are locked in the closed position. like Figures 1 to 3As shown, the femoral artery pressurized tourniquet also includes an inflatable pressurized structure, which is arranged on the first tourniquet 2. The inflatable pressurized structure includes a sliding frame 81, and the sliding frame 81 is slidably sleeved on the first tourniquet 2. The inflatable pressurized structure also includes: a pressurized bag 82, which is fixed to the side of the sliding frame 81; an inflatable bag 83; an air guide tube 84, one end of which is connected to the inflatable bag 83, and the other end of which is connected to the pressurized bag 82; an air inlet pipe 85, which is fixed to the inflatable bag 83 and connected to the interior of the inflatable bag 83, and both the air guide tube 84 and the air inlet pipe 85 are provided with a one-way flow limiting structure; like Figure 7 , Figure 8 As shown, the femoral artery pressurized tourniquet also includes a positioning structure, which is arranged on the sliding frame 81 and is used to fix the sliding frame 81 on the first tourniquet 2. The positioning structure includes: a fixed cover 91, which is fixed to the side of the sliding frame 81, and the interior of the fixed cover 91 is hollow; a connecting rod 92, which passes through the fixed cover 91 and the sliding frame 81, and is slidably connected between the fixed cover 91 and the sliding frame 81; a pointed head 93, which is fixed to one end of the connecting rod 92 located inside the sliding frame 81, and the pointed head 93 is a pointed structure; two positioning springs 94, one end of which is fixedly connected to the middle position of the inner surface of the fixed cover 91, and the other end is fixedly connected to the connecting rod 92, and the two positioning springs 94 are both in an arc-shaped structure; a pressing button 95, which is fixed to one end of the connecting rod 92 located outside the fixed cover 91; When applying pressure to stop bleeding on a patient's wound, the staff puts the ring-shaped structure formed by the first tourniquet 2 and the second tourniquet 3 on the patient's wound position, and then adjusts the position of the pressurized bag 82 so that the pressurized bag 82 is directly opposite the wound. In addition, the first tourniquet 2 and the second tourniquet 3 are connected by a connecting buckle 1. The position of the connecting buckle 1 facilitates the staff to adjust the size of the ring-shaped structure formed by the first tourniquet 2 and the second tourniquet 3 so that the first tourniquet 2 and the second tourniquet 3 can fit the patient's skin. The specific structure and workmanship of the connecting buckle 1 The working principle is not an innovative part of the present technical solution and is not shown in the figure and will not be described in detail here. When adjusting the position of the pressurized bag 82, the medical staff first pulls the pressure button 95 to make the pressure button 95 drive the connecting rod 92 to move. When the connecting rod 92 moves, it can drive the pointed head 93 to move until the pointed head 93 is separated from the first tourniquet 2. Without the restriction of the pointed head 93, the sliding frame 81 can slide freely on the first tourniquet 2. When the sliding frame 81 moves, the pressurized bag 82 thereon will also move accordingly. After adjusting the pressurized bag 82 to a suitable position, the staff The pressing button 95 is pressed again, so that the pointed tip 93 presses the first tourniquet 2. At this time, the pointed tip 93 fixes the sliding frame 81, and the position of the pressurizing bag 82 is also fixed. Furthermore, the connecting rod 92 is connected to the fixing cover 91 by two arc-shaped positioning springs 94. When the pointed tip 93 is separated from the first tourniquet 2, the two positioning springs 94 are deformed in the direction close to the pressing button 95. At this time, under the elastic force of the two positioning springs 94 themselves, the position of the connecting rod 92 will be fixed. When the connecting rod 92 moves, the two positioning springs 9 4 will be deformed. When the pointed head 93 presses the first tourniquet 2, the two positioning springs 94 are deformed in the direction close to the first tourniquet 2. At this time, the two positioning springs 94 will return to their original state. In this case, under the elastic force of the two positioning springs 94, the position of the connecting rod 92 will also be fixed. Therefore, under the elastic force of the two positioning springs 94, when the pointed head 93 is away from the first tourniquet 2 or the pointed head 93 presses the first tourniquet 2, the position of the connecting rod 92 will be fixed, which is convenient for the staff to flexibly adjust the position of the pointed head 93; like Fig. 9As shown, the femoral artery pressurized tourniquet also includes an air volume regulating structure, which is arranged on the inflation pressurized structure, and the air volume regulating structure includes: an adjusting sleeve 101, which is movably inserted in the air inlet pipe 85; a plurality of first air inlets 102, all of which are provided on the adjusting sleeve 101; a limiting opening 103, which is provided on the air inlet pipe 85; a limiting block 104, which is fixed on the adjusting sleeve 101, and the limiting block 104 is slidably provided in the limiting opening 103; a damping ring 105, which is slidably sleeved on the air inlet pipe 85 and fixedly connected to the limiting block 104, the inner ring of the damping ring 105 and the outer surface of the air inlet pipe 85 are mutually fitted, and the damping ring 105 is made of rubber material; a plurality of second air inlets 106, all of which are provided on the air inlet pipe 85, and the plurality of first air inlets 102 are respectively provided opposite to the plurality of second air inlets 106; When the pressurized bag 82 is facing the patient's wound, the staff continuously squeezes the inflatable bag 83 to make the inflatable bag 83 pump gas into the pressurized bag 82, thereby gradually inflating the pressurized bag 82 and applying a certain pressure to the patient's wound. The inflatable bag 83 is connected to an air guide tube 84 and an air inlet pipe 85. Both the air guide tube 84 and the air inlet pipe 85 are provided with a one-way flow limiting structure. Under the action of the two one-way flow limiting structures, when the staff presses the inflatable bag 83, the gas inside the inflatable bag 83 will be pressed into the pressurized bag 82 through the air guide tube 84. When the staff releases the inflatable bag 83, the inflatable bag 83 will return to its original state under the action of its own elastic force. At this time, the inflatable bag 83 can pass through the air inlet pipe 85 extracts gas from the external environment, which makes it easier for the inflatable bag 83 to continuously pump gas into the pressurized bag 82. The one-way flow limiting structure is a common design in the prior art, which is not shown in the figure and will not be described in detail here. In addition, a gas volume adjustment structure is also provided on the pressurized bag 82. In the initial stage of inflation, the staff can adjust the air inlet pipe 85 to the maximum air intake through the air volume adjustment structure, which enables the pressurized bag 82 to be inflated and expanded quickly. When the pressurized bag 82 expands to fit the position of the patient's wound, the staff reduces the air intake of the air inlet pipe 85 through the air volume adjustment structure to make the pressurized bag 82 expand slowly. This design is conducive to the staff to accurately adjust the pressure applied by the pressurized bag 82 on the patient's wound. , to avoid discomfort to the patient. Specifically, for the air volume adjustment structure, a slidable adjustment sleeve 101 is provided in the air inlet pipe 85, a plurality of second air inlets 106 are provided on the air inlet pipe 85, and a plurality of first air inlets 102 are provided on the adjustment sleeve 101. When the plurality of first air inlets 102 and the plurality of second air inlets 106 completely overlap, the air inlet pipe 85 has a maximum air intake volume. When the staff pulls the adjustment sleeve 101, the plurality of first air inlets 102 will move accordingly, which makes the plurality of first air inlets 102 and the plurality of second air inlets 106 staggered with each other. At this time, the overlapping portion between the plurality of first air inlets 102 and the plurality of second air inlets 106 will be reduced, and the air inlet pipe 85 The air intake volume will also decrease accordingly. In summary, the staff can adjust the air intake volume of the air intake pipe 85 by pulling the adjusting sleeve 101. When the adjusting sleeve 101 is moving, the limiting opening 103 and the limiting block 104 limit the movement of the adjusting sleeve 101. When the limiting block 104 is located at one end of the limiting opening 103, the first air intake ports 102 and the second air intake ports 106 are exactly opposite to each other. At this time, the air intake pipe 85 has the maximum air intake volume. When the limiting block 104 is located at the other end of the limiting opening 103, the ends of the first air intake ports 102 coincide with the ends of the second air intake ports 106. At this time, the air intake pipe 85 has the minimum air intake volume. In addition, a damping ring 105 is fixed on the limit block 104, and the inner ring of the damping ring 105 fits with the outer surface of the intake pipe 85, which makes there be a large friction between the damping ring 105 and the intake pipe 85. Under the action of this friction, the adjustment sleeve 101 will not move under non-human circumstances. This design can ensure the stability of the adjustment sleeve 101.
