Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pelvic fixing tourniquet for trauma. Background Art

[0002] Pelvic fracture is a serious trauma, mostly caused by direct violent pelvic compression, which is more common in traffic accidents and landslides, and in wartime, it is a firearm injury; more than half of pelvic fracture trauma is accompanied by complications or multiple injuries, the most serious of which is traumatic hemorrhagic shock and combined injuries to pelvic organs. Improper treatment has a high mortality rate. During the first aid and transportation of pelvic fractures, the first thing to do is to stabilize the pelvic ring structure. Traditional pelvic fracture fixation belts are mostly ordinary abdominal belts, which are tightened manually and fixed with Velcro. In actual use, they often have defects such as unreliable fixation, slippage, insufficient contraction of the pelvic belt, and poor control of bleeding. At the same time, pelvic fractures are often accompanied by multiple injuries, especially for bleeding in the junction area such as the groin area, and general tourniquets are often ineffective.

[0003] The application number is CN201821219788.5, which provides a pelvic fracture fixation belt, including a belt body I, a belt body II and a compression device, the right side of the belt body I is connected to the left side of the belt body II by an elastic connecting belt, and the right side of the belt body II is provided with a connecting device for connecting to the left side of the belt body I; the compression device includes a box body and an airbag I arranged in the box body, the box body is provided with an inflation nozzle I connected to the airbag I, the box body is detachably connected to the inner surface of the belt body I and / or the inner surface of the belt body II; the connecting device includes a connecting belt I and a connecting belt II connected to the connecting belt I by a drawstring, the connecting belt I is fixed to the belt body II, and the connecting belt II is detachably connected to the belt body I; the utility model can be tightened quickly, and can effectively control pelvic fracture bleeding, including bleeding at the junction of the groin area.

[0004] However, the above technical solution cannot accurately observe the pressure of the fixing belt on the human body. When the fixing belt is loose, the patient cannot be tightened in time, and the bleeding of pelvic fractures including bleeding at the junction of the groin area cannot be effectively controlled. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pelvic fixing tourniquet for trauma, wherein a pull rope is driven to be reeled in by rotating a knob. Since the pull rope is wound around a plurality of fixed pulleys on a connecting plate, when the pull rope is reeled in, a pulling force is generated on the connecting plate, so that the two connecting plates are brought closer to each other, thereby achieving the fastening of the fixing belt of the device to the patient's pelvis and stabilizing the pelvic structure. Since the knob has a built-in tension sensor, the pressure of the device on the pelvic structure can be effectively controlled.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pelvic tourniquet for trauma fixation comprises two connecting plates, wherein a plurality of fixed pulleys are arranged in an array on one side of the two connecting plates that are close to each other on the front side, and the two connecting plates that are close to each other on the back side are connected by an elastic mesh surface, a drawstring is wound between the plurality of fixed pulleys, a knob is installed in the middle of the upper end of the front side of the elastic mesh surface, and two free ends of the drawstring are connected to the knob, a compression hemostatic piece is arranged in the middle of the connecting plates, a fixing belt is arranged on the side of one of the connecting plates away from the fixed pulley, an extension belt is arranged on the end of the fixing belt away from the connecting plate, and a buckle adapted to the extension belt is arranged on the side of the other connecting plate away from the fixed pulley, a tension sensor is built in the knob, and a display screen of the tension sensor is arranged on the front side of the knob.

[0008] Preferably, the compression hemostatic component includes two compression devices, and the two compression devices are respectively arranged on the back sides of the corresponding connecting plates. A threaded hole is opened in the middle of the connecting plate, and a threaded rod rotatably connected to the compression device is arranged in the threaded hole. A rotating handle is arranged at one end of the threaded rod away from the compression device, and the rotating handle is arranged on the front side of the connecting plate.

[0009] Preferably, arc-shaped windows are provided on the connecting plates at the upper and lower ends of the rotating handle, and scales are set on the arc-shaped windows. The two arc-shaped windows are located on the back side of the connecting plates and are the upper and lower ends of the compression device, and pointers matching the scales are set at the upper and lower ends of the compression device.

[0010] Preferably, the compression device includes a reinforcing plate, which is rotatably connected to the end of the threaded rod, a compression plate is provided on the side of the reinforcing plate away from the threaded rod, both ends of the compression plate are arc-shaped structures, and chamfers are provided on the four sides of the compression plate.

[0011] Preferably, there are multiple fixing belts, and the multiple fixing belts are evenly arranged on one side of the connecting plate. The multiple fixing belts are connected by elastic belts arranged in a Z shape, and the ends of the multiple fixing belts away from the connecting plate are connected by a connecting belt.

[0012] Preferably, a plurality of extension straps are provided on a side of the connecting strap away from the fixing strap, the number of the buckles is the same as the number of the extension straps, and Velcro is provided on the surface of the extension straps.

[0014] Preferably, a protective cover is provided on one side of the plurality of fixed pulleys on the two connecting plates close to the rotating handle.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model has a simple structure. The device is fixed by inserting an extension belt into a buckle so that the device fits on the patient's body surface. The pull rope is driven to be reeled in by rotating the knob. Since the pull rope is wound around multiple fixed pulleys on the connecting plate, when the pull rope is reeled in, a pulling force is generated on the connecting plate, so that the two connecting plates are brought closer to each other, thereby realizing that the fixing belt of the device is fastened to the patient's pelvis to stabilize the pelvic structure. Since the knob has a built-in tension sensor and a display screen of the tension sensor is provided on the front of the knob, the pressure of the device on the pelvic structure can be effectively controlled to avoid excessive pressure, which may cause secondary injuries to the patient, and to avoid the device from being loosened and unable to effectively stabilize the pelvic structure. The pressure of the device on the patient can be observed in real time through the display screen, which is convenient for timely regulation and improves the practicality of the device.

[0017] 2. The elastic mesh surface of the device can cover the patient, so that the patient's body surface is always on the back of the connecting plate, avoiding squeezing the patient's body surface when the connecting plates are brought closer to each other due to the rotation of the knob, causing secondary injury to the patient, and at the same time plays the effect of connecting the two connecting plates.

[0018] 3. The device drives the threaded rod to rotate in the threaded hole by rotating the rotating handle, thereby driving the compression hemostasis device to compress and stop bleeding at the bleeding position of the patient. Since the compression hemostasis device and the threaded rod are rotatably connected, when the threaded rod rotates, the compression hemostasis device in contact with the patient's body can always maintain a relatively unchanged angle with the patient, thereby avoiding the compression hemostasis component from twisting on the patient's body surface due to the rotation of the rotating handle, causing damage to the patient's skin or tissue, thereby improving the practicality of the device.

[0019] 4. The window of this device can observe the rotation angle of the compression device. In order to better fit the compression device to the wound at the patient's groin, the rotation angle of the compression device can be accurately controlled by the pointer on the compression device and the scale at the window position, thereby further improving the practicality of this device and the compression effect on the patient's bleeding position.

[0020] 5. The arc-shaped structures at both ends of the compression plate of the device can better fit the human body to avoid harming the patient, and the chamfers on the four sides of the compression plate can prevent the edges of the compression plate from causing damage to the patient when the compression plate is tightened and compressed on the patient.

[0021] 6. The multiple fixing straps of the device can better fit the curve of the patient's pelvis, improve the fit between the device and the human body, and ensure that the device achieves the best fastening effect on the patient.

[0022] 7. The outside of the connecting plate of the device is covered with sponge, which not only provides hemostatic pressure at the junction, but also avoids damage to the patient's bones. The hard sponge on the surface of the compression device also avoids damage to the patient and provides a certain degree of body comfort. The waterproof fabric on the connecting plate and the surface of the compression device can prevent the blood from seeping into the sponge, resulting in ineffective cleaning. It is convenient for patients to clean and disinfect it after use, and facilitate subsequent reuse, thereby improving the utilization rate and service life of the device.

[0023] 8. The device is provided with a protective cover to prevent the pull rope from slipping off the fixed pulley in a relaxed state, so that the device can directly tighten the patient, thereby improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1

[0032] A pelvic fixation tourniquet for trauma, the structure of which is as follows Figure 1-Figure 5As shown, it includes two connecting plates 1, and a plurality of fixed pulleys 2 are arranged in an array on one side of the two connecting plates 1 that are close to each other on the front side, and the two connecting plates 1 that are close to each other on the back side are connected by an elastic mesh 3, and a pull rope 5 is wound between the plurality of fixed pulleys 2, and a knob 4 is installed in the middle of the upper end of the front side of the elastic mesh 3, and the two free ends of the pull rope 5 are connected to the knob 4, and a compression hemostatic part is arranged in the middle of the connecting plate 1, and a fixing belt 9 is arranged on the side of one of the connecting plates 1 away from the fixed pulley 2, and an extension belt 14 is arranged on the end of the fixing belt 9 away from the connecting plate 1, and a buckle 16 adapted to the extension belt 14 is arranged on the side of the other connecting plate 1 away from the fixed pulley 2, and the knob 4 has a built-in tension sensor, and a display screen of the tension sensor is arranged on the front of the knob 4.

[0033] When using the device, the device is wrapped around the patient's pelvis, and the device is fixed by inserting the extension belt 14 into the buckle 16 to make the device fit the patient's body surface, and the pull rope 5 is driven to be rolled up by rotating the knob 4. Since the pull rope 5 is wound around the multiple fixed pulleys 2 on the connecting plate 1, when the pull rope 5 is rolled up, a pulling force is generated on the connecting plate 1, so that the two connecting plates 1 are close to each other, thereby achieving the fastening of the fixing belt 9 of the device to the patient's pelvis to stabilize the pelvic structure. The knob 4 has a built-in tension sensor, and a display screen of the tension sensor is provided on the front of the knob 4, which can effectively control the pressure of the device on the pelvic structure to avoid excessive pressure, resulting in secondary injuries to the patient, and to avoid the device from being loosened and unable to effectively stabilize the pelvic structure. The pressure of the device on the patient can be observed in real time through the display screen, which is convenient for timely regulation and improves the practicality of the device.

[0034] The elastic mesh 3 arranged between the connecting plates 1 can cover the patient, so that the patient's body surface is always on the back of the connecting plate 1, to avoid the patient's body surface being squeezed when the connecting plates 1 are brought closer to each other due to the rotation of the knob 4, causing secondary injury to the patient, and at the same time, it has the effect of connecting the two connecting plates 1.

[0035] The compression hemostatic component includes two compression devices 8, and the two compression devices 8 are respectively arranged on the back sides of the corresponding connecting plates 1. A threaded hole is opened in the middle of the connecting plate 1, and a threaded rod 12 rotatably connected to the compression device 8 is arranged in the threaded hole. A rotating handle 11 is arranged at the end of the threaded rod 12 away from the compression device 8, and the rotating handle 11 is arranged on the front side of the connecting plate 1.

[0036] When the patient has bleeding in the pelvis, the threaded rod 12 is driven to rotate in the threaded hole by rotating the rotating handle 11, thereby driving the compression hemostasis device to compress and stop bleeding at the bleeding position of the patient. Since the compression hemostasis device and the threaded rod 12 are rotatably connected, when the threaded rod 12 rotates, the compression hemostasis device in contact with the patient's body can always maintain a relatively unchanged angle with the patient, thereby avoiding the compression hemostasis component from twisting on the patient's body surface due to the rotation of the rotating handle 11, causing damage to the patient's skin or tissue, thereby improving the practicality of the device.

[0037] The connecting plates 1 at the upper and lower ends of the rotating handle 11 are provided with arc-shaped windows 6, on which scales 7 are arranged. The two arc-shaped windows 6 are located on the back side of the connecting plate 1 as the upper and lower ends of a compression device 8, and the upper and lower ends of the compression device 8 are provided with pointers 13 adapted to the scales 7.

[0038] The compression device 8 is a long strip structure. When the patient's groin area or other junction areas are bleeding, the rotation angle of the compression device 8 can be observed through the window 6. In order to better make the compression device 8 fit the wound at the patient's groin position, the rotation angle of the compression device 8 can be accurately controlled by the pointer 13 on the compression device 8 and the scale 7 at the position of the window 6, thereby further improving the practicality of the device and the compression effect on the patient's bleeding position.

[0039] The compression device 8 includes a reinforcing plate, which is rotatably connected to the end of the threaded rod 12. A compression plate is provided on the side of the reinforcing plate away from the threaded rod 12. The two ends of the compression plate are arc-shaped structures, and the four sides of the compression plate are chamfered.

[0040] The compression plate is long and strip-shaped, which is convenient for effectively compressing and stopping the bleeding in the patient's groin area. The reinforcing plate can ensure the structural strength of the compression device 8. The arc-shaped structures at both ends of the compression plate can better fit the human body to avoid harming the patient. The chamfers on the four sides of the compression plate can prevent the edges of the compression plate from causing damage to the patient when the compression plate is tightened to compress the patient.

[0041] There are multiple fixing belts 9, and the multiple fixing belts 9 are evenly arranged on one side of the connecting plate 1. The multiple fixing belts 9 are connected by a Z-shaped elastic belt 10, and the ends of the multiple fixing belts 9 away from the connecting plate 1 are connected by a connecting belt.

[0042] The multiple fixing belts 9 are connected by elastic belts 10. Compared with a wider single fixing belt 9, the multiple fixing belts 9 can move away from and close to each other. The human pelvis generally has a certain curve. The multiple fixing belts 9 can better fit the curve of the patient's pelvis, improve the fit between the device and the human body, and ensure that the device achieves the best fastening effect on the patient.

[0043] A plurality of extension straps 14 are arranged on one side of the connection strap away from the fixing strap 9 . The number of the buckles 16 is the same as that of the extension straps 14 . Velcro 15 is arranged on the surface of the extension straps 14 .

[0044] A plurality of extension straps 14 are inserted into the corresponding buckles 16 to achieve the fixing effect of the device. Since the extension straps 14 have a certain length, when the extension straps 14 are inserted into the buckles 16, the extension straps 14 will have longer or shorter margins depending on the pelvic circumference of the patient. When the patient's pelvic circumference is larger, the excess extension straps 14 are shorter and will not cause any impact. When the patient's pelvic circumference is smaller, the excess extension straps 14 will be longer. The Velcro 15 can be used to reasonably store the excess extension straps 14 to avoid the possibility that the extension straps 14 are longer and rub against the patient's skin, thereby affecting the patient's comfort.

[0045] Embodiment 2

[0046] On the basis of the first embodiment, the surface of the connecting plate 1 is covered with a sponge, the surface of the sponge is covered with a waterproof fabric, and the surface of the compression device 8 is covered with a hard sponge, and the surface of the hard sponge is provided with a waterproof fabric.

[0047] The connecting plate 1 is made of a lightweight hard material and is covered with a sponge on the outside of the connecting plate 1, which not only provides hemostatic pressure at the junction but also avoids damage to the patient's bones. The hard sponge on the surface of the compression device 8 also avoids damage to the patient and provides a certain degree of physical comfort. The waterproof fabric on the surface of the connecting plate 1 and the compression device 8 can prevent the blood from seeping into the sponge, resulting in ineffective cleaning. This makes it convenient for the patient to clean and disinfect it after use, facilitates subsequent reuse, and improves the utilization rate and service life of the device.

[0048] Embodiment 3

[0049] On the basis of the first embodiment, a protective cover is provided on one side of the plurality of fixed pulleys 2 on the two connecting plates 1 close to the rotating handle 11 .

[0050] When the device is not fastened to the patient, the pull rope 5 on the fixed pulley 2 is in a loose state. By providing a protective cover, the pull rope 5 in the loose state can be prevented from slipping off the fixed pulley 2, so that the device can directly fasten the patient, thereby improving the convenience of using the device.

[0051] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
