Description

Technical Field

[0001] The present invention relates to the technical field of emergency rescue, in particular to a medical emergency limb rescue hemostasis device. Background Art

[0002] The process of quickly stopping the outflow of blood through certain methods is called hemostasis. The effect of hemostasis varies from person to person, some are fast, some are slow. It is related to platelets. The human body can stop bleeding in a short time. The process mainly includes three processes: vasoconstriction, platelet thrombosis and blood coagulation. Under normal circumstances, bleeding caused by damage to small blood vessels will stop on its own within a few minutes. This phenomenon is called physiological hemostasis. Physiological hemostasis is one of the important protective mechanisms of the body.

[0003] Passive hemostasis refers to a condition in which a large amount of bleeding occurs in a short period of time or the bleeding rate is very fast. In this case, external intervention is usually required to treat the damaged blood vessels to stop the rapid bleeding and avoid a rapid decrease in blood volume, which may cause shock and other dangerous situations. For example, during training in special environments, the trainees' limbs will inevitably suffer local injuries. The situation at this time is usually more urgent and the wound is difficult to heal on its own, so first aid methods are needed to stop the bleeding;

[0004] The existing emergency hemostasis measures include using hemostatic forceps or manual pressure to stop bleeding. Since hemostatic forceps are difficult to use, it is easy to increase the difficulty of rescue by medical personnel. If the rescue personnel have low professionalism, it is easy to slow down the progress of patient rescue. The manual pressure method is time-consuming and labor-intensive, which is not conducive to medical personnel taking other rescue measures such as suturing the wound. There is also a hemostasis method of binding the limbs with bandages. This method cannot press the local part of the limbs to stop bleeding and often requires multiple wraps. Although it can achieve the purpose of hemostasis, it is easy to damage other healthy blood vessels. Therefore, traditional emergency hemostasis equipment is still inconvenient in actual use, which is not conducive to the subsequent recovery of patients and needs to be improved. Summary of the Invention

[0025] Optionally, two sponge pads are fixedly connected to the inner wall of the second device body, and the two sponge pads are arranged symmetrically on the left and right.

[0026] Optionally, the surfaces of the two locking plates are fixedly connected to pressing blocks, and the surfaces of the two pressing blocks are provided with anti-slip patterns.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention can ensure the firmness of the connection between the first device body and the second device body by setting up structures such as electromagnets and iron sheets, and ensure the effectiveness of subsequent first aid measures such as compression to stop bleeding.

[0029] Second, the present invention uses the cooperation of the slider, the second fixed axis, and the hinged rod group to enable the pressing plate to compress the blood vessels where hemostasis is required. Compared with traditional methods, it does not damage healthy blood vessels in other parts of the limb and can achieve a localized hemostatic compression process.

[0030] At the same time, compared with the plate driver, the pressing plate driver will be faster in displacement. The pressing plate driver can quickly move downward to quickly compress the corresponding area to stop bleeding. This process can meet the core requirements of emergency response and rapid treatment, and is more conducive to the first aid process for patients.

[0031] Third, the present invention uses the coordination of the shaft, friction rod, and friction wheel to allow the two arc-shaped plate driving elements to deflect as they follow the displacement of the pressing plate driving element, thereby cooperating with the pressing plate driving element to more closely conform the compression and hemostasis of the limb to the curvature of the limb, thereby achieving a better compression effect.

[0032] Compared with the method of directly using a structure with a certain curvature shape to displace the body, this method can save more space, making it more convenient to attach the device to the limb and more conducive to the emergency treatment process.

[0033] At the same time, the threaded rod driving element can be rotated and adjusted to make the friction rod and the two friction wheel driving elements misaligned, thereby adding two additional arc plate driving elements that will not be passively deflected. In this way, when the pressing plate driving element presses to stop bleeding, the two arc plate driving elements will only fit the skin under the action of gravity, but will not compress the skin. This measure can expand the adaptability of the equipment, allowing emergency personnel to choose the required hemostasis plan as needed.

[0034] Fourth, the present invention cooperates with the ratchet gear, the locking plate 1 and the locking plate 2, so that when compression is completed, the locking plate 2 driving element can lock the state of compression and hemostasis, making it easier for medical staff to take other emergency measures.

[0035] At the same time, when it is necessary to release the hemostatic pressure, it is necessary to manually press the locking plate and the driving element on both sides with both hands at the same time to release it. In this way, in the process of releasing the pressure and removing the equipment, the personnel are forced to use both hands, making the removal process smoother and more conducive to the patient's recovery, and avoiding the situation where some personnel relax their vigilance after the rescue is completed, and take the equipment with one hand out of luck, so as to touch the wound.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1:

[0049] See also Figures 1 to 10 The present invention provides a technical solution: a medical emergency limb rescue hemostasis device, comprising a device body 1 and a device body 2, wherein the device body 1 and the device body 2 can be engaged with each other through a connecting component, and a plate 3 is slidably connected to the inner wall of the device body 1, and a displacement groove is opened on the surface of the plate 3;

[0050] A pressing plate 4 is provided in the device body 1, and a pressing rod 5 is fixedly connected to the top surface of the pressing plate 4. The inner wall of the pressing rod 5 is slidably connected to a limit rod 6. The upper end of the limit rod 6 is fixedly connected to the inner wall of the device body 1. Two arc-shaped plates 7 are provided in the pressing plate 4;

[0051] It also includes two sets of hemostatic components, both of which are arranged in the device body 1. Through the arrangement of the two sets of hemostatic components, the pressing plate 4 can be displaced relatively quickly in the vertical direction.

[0052] It also includes a matching component, which is transmission-connected to both sets of hemostatic components. Through the arrangement of the matching component, when the pressing plate 4 moves, the two arc-shaped plates 7 follow the displacement and deflect at the same time.

[0053] It also includes two sets of locking components, which are respectively arranged on the two sets of hemostasis components. The state of the pressing rod 5 is limited by the arrangement of the two sets of locking components.

[0054] The matching component is also provided with an adjusting component and a driving component, and the driving component is electrically connected to the connecting component.

[0055] More specifically, in this embodiment, when bleeding occurs in a person's arm, emergency hemostasis treatment is required. The device can be removed, and the device body 1 and the device body 2 2 are engaged above the bleeding part of the limb, so that the position of the pressing plate 4 is the position of the blood vessel to be compressed for hemostasis. At this time, the connection component ensures that the device body 1 and the device body 2 2 are kept tightly together and do not fall off. The driving component can be activated first to move the plate 3 in the direction close to the skin. Therefore, through the synchronous operation of the two sets of hemostasis components, the pressing plate 4 can be displaced relatively quickly, pressing the blood vessel to achieve the purpose of rapid hemostasis.

[0056] During this process, the matching components are driven synchronously to operate, so that when the pressing plate 4 is displaced, the two curved plates 7 follow the displacement and deflect at the same time. Therefore, through the cooperation of the two curved plates 7 and the pressing plate 4, the hemostatic pressure on the patient's limb is more closely fitted to the curvature of the limb, so that the compression and hemostasis effect is better. In the process of the operation of the two sets of hemostatic components, the two sets of locking components are driven synchronously to operate, so that the displacement state of the pressing rod 5 is limited, so that it cannot be easily reset, thereby ensuring the continuity of the hemostatic state and facilitating wound treatment by medical staff.

[0057] By setting the adjustment component, the status of the two arc-shaped plates 7 can be controlled, and the situation in which they follow but do not actively deflect can be additionally increased, thereby further expanding the scope of application of the device.

[0058] It is worth noting that two sponge pads 33 are fixedly connected to the inner wall of the device body 2, and the two sponge pads 33 are symmetrically arranged on the left and right. Therefore, through the arrangement of the two sponge pads 33, the area where the patient does not need to be compressed can be more comfortable, and the device can fit the patient's limbs better.

[0059] Furthermore, the driving component includes: a driving element 31, which is fixedly connected to the inner wall of the device body 1, and the output end of the driving element 31 is fixedly connected to a threaded rod 32, and the surface of the plate 3 is provided with an opening for the threaded rod 32 to pass through and be threadedly connected thereto.

[0060] Thus, by starting the driving element 31, the threaded rod 32 can be rotated, and the rotation of the threaded rod 32 can cause the plate 3 to be displaced under the limit of the device body 1;

[0061] When the driving element 31 is started, the electromagnet 8 can be energized at the same time, thereby maintaining a firm connection between the device body 1 and the device body 2 2.

[0062] It is worth noting that the driving element 31 can drive the threaded rod 32 to rotate by a built-in motor, and the process of outputting current through the driving element 31 can be completed by an additional built-in current output terminal. The components involved in these two measures are common driving devices on the market, so the specific principles will not be described in detail here.

[0063] When the hemostatic pressure is released, the threaded rod 32 is reversely rotated by the driving element 31, and the electromagnet 8 can be powered off, at which time the device body 1 and the device body 2 2 are automatically separated.

[0064] Example 2, based on the above example:

[0065] See also Figure 1The connecting components in Example 1 are disclosed as follows: the connecting components include: two electromagnets 8, the two electromagnets 8 are fixedly connected to both sides of the device body 1, and two iron sheets 9 are fixedly connected to the inner wall of the device body 2.

[0066] More specifically, in this embodiment: when the device body 1 and the device body 2 are engaged, the two iron sheets 9 can be respectively fitted with the two electromagnets 8. At this time, the electromagnets 8 are energized by the driving components to attract the fitted iron sheets 9, thereby maintaining the connection between the device body 1 and the device body 2 2.

[0067] Example 3, based on the above example:

[0068] See also Figures 1 to 7 The hemostatic component in Example 1 is disclosed as follows: the hemostatic component includes: a slider 10, the slider 10 is slidably connected to the surface of the plate 3, the surface of the slider 10 is rotatably connected to a fixed axis 11, the inner wall of the device body 1 is rotatably connected to a fixed axis 2 12, the axis arm of the fixed axis 11 is fixedly connected to a deflection rod 13, the end of the deflection rod 13 is fixedly connected to the axis arm of the fixed axis 2 12, the groove wall of the displacement groove is slidably connected to a hemostatic block 14, the surface of the hemostatic block 14 is slidably connected to a rack row 15, the axis arm of the fixed axis 11 is fixedly connected to a gear 16, the teeth of the gear 16 are engaged with the teeth of the rack row 15, the lower end of the rack row 15 is hinged to a hinged rod group 17, the end of the hinged rod group 17 is hinged to the rod arm of the pressing rod 5, the axis arm of the fixed axis 11 is rotatably connected to a limiting sleeve 35, and the limiting sleeve 35 is fixedly connected to the surface of the hemostatic block 14.

[0069] More specifically, in this embodiment, the plate 3 moves downward along the inner wall of the device body 1, thereby driving the slider 10 to move synchronously. Since the slider 10 is also limited by the fixed axis 12, the slider 10 moves toward the pressing rod 5 while following the downward movement. During this process, the deflection rod 13 deflects about the fixed axis 12, thereby causing the gear 16 to deflect about the fixed axis 12.

[0070] In the above process, first, the gear 16 is displaced in an arc trajectory to push the rack row 15 toward the pressing rod 5. During this process, the hemostatic block 14 slides along the groove wall of the displacement groove, and the setting of the limit sleeve 35 makes the hemostatic block 14 maintain a synchronous motion state with the fixed axis 11. In the process of the rack row 15 approaching the direction of the pressing rod 5, the gear 16 is slightly deflected, and the rack row 15 is also slightly displaced vertically downward. During this process, the rack row 15 slides along the surface of the hemostatic block 14. In summary, the movement form of the rack row 15 during the displacement of the plate 3 is that while it is displaced vertically downward, it will also approach the direction of the pressing rod 5. In this way, the rack row 15 moves toward the direction of the pressing rod 5. When the two arms of the pressing rod 5 are brought closer together, the hinged rod group 17 can be pushed to deflect, thereby pushing the pressing rod 5 to move downward along the arm of the limiting rod 6, thereby causing the pressing plate 4 to move downward through the transmission of the pressing rod 5, and at the same time, the rack row 15 itself will also move downward in the vertical direction, that is, the pressing plate 4 will be driven by more than one factor during displacement, and its speed will be faster than that of the plate 3, so that the pressing plate 4 can move downward faster than the traditional method, thereby quickly compressing and stopping bleeding in the corresponding area, and adapting to the core requirement of emergency and rapid treatment through the rapidity of its movement, and can also achieve local hemostatic compression, which will not damage healthy blood vessels in other parts of the limb compared to the traditional method.

[0071] Example 4, based on the above example:

[0072] See also Figures 1 to 7 The mating components in Example 1 are disclosed as follows. The mating components include: two mating shafts 18, both mating shafts 18 are rotatably connected to the inner wall of the pressing rod 5, and the ends of the two mating shafts 18 are fixedly connected to friction wheels 19. The inner wall of the device body 1 is slidably connected to a friction rod 20, and the side walls of the two friction wheels 19 are in contact with the lever arms of the friction rod 20. The upper end of the friction rod 20 is fixedly connected to an adjustment block 21, and the adjustment block 21 is movably connected to the inner wall of the device body 1 through the adjustment component;

[0073] The inner wall of the pressing plate 4 is rotatably connected to two deflection shafts 22, and the two deflection shafts 22 are respectively connected to the shaft arms of the two mating shafts 18 through a pulley assembly 23. The shaft arms of the two deflection shafts 22 are fixedly connected to the deflection blocks 24, and the two arc plates 7 are respectively fixedly connected to the surfaces of the two deflection blocks 24.

[0074] More specifically, in this embodiment: during the displacement of the above-mentioned pressing rod 5, the two mating shafts 18 are synchronously driven to displace, so that the two friction wheels 19 are displaced downward along the arm of the friction rod 20 through the transmission of the two mating shafts 18. Through the setting of the friction rod 20, the two friction wheels 19 are deflected during the displacement, that is, the two mating shafts 18 are deflected while following the displacement, so that through the transmission of the two pulley assemblies 23, the two deflection shafts 22 are deflected while following the displacement, and then through the transmission of the two deflection blocks 24, the two arc plates 7 are deflected while following the displacement of the pressing plate 4. Through the deflection of the two arc plates 7, they cooperate with the pressing plate 4, and the compression and hemostasis of the limb are more in line with the curvature of the limb, so that the compression effect is better. Compared with the method of directly adopting the displacement of a structure with a certain curvature shape, this method can save more occupied space, making the equipment more convenient when it is engaged on the limb, and more conducive to the emergency treatment process.

[0075] Example 5, based on the above example:

[0076] See also Figures 2 to 7 The adjusting component in the first embodiment is disclosed as follows: the adjusting component includes: an adjusting threaded rod 25, the adjusting threaded rod 25 is rotatably connected to the inner wall of the device body 1, and a threaded opening is provided on the surface of the adjusting block 21 for the adjusting threaded rod 25 to pass through and be threadedly connected thereto.

[0077] More specifically, in this embodiment: during actual use, the adjusting threaded rod 25 can be rotated to make the adjusting block 21 approach the direction of the pressing rod 5. This approaching process limits the friction rod 20 through the device body 1, that is, during this process, the friction rod 20 slides along the inner wall of the device body 1, and the displacement of the driven friction rod 20 can make it misaligned with the two friction wheels 19, so that the friction wheel 19 will not be passively deflected during displacement, that is, through this adjustment, the two arc plates 7 will not be passively deflected, so that in the process of the pressing plate 4 pressing to stop bleeding, the two arc plates 7 will only fit the skin under the action of gravity, but will not compress the skin, which can expand the adaptability of the equipment and allow emergency personnel to choose the required hemostasis scheme as needed.

[0078] Example 6, based on the above example:

[0079] See also Figures 1 to 10, the locking component in Example 1 is disclosed as follows, the locking component includes: a ratchet gear 26, the ratchet gear 26 is fixedly connected to the shaft arm of the fixed shaft 2 12, the inner wall of the device body 1 is slidably connected with a locking plate 1 27, the surface of the locking plate 1 27 is fixedly connected with a spring 1 28, the end of the spring 1 28 is fixedly connected to the inner wall of the device body 1, the inner wall of the locking plate 1 27 is slidably connected with a locking plate 2 29, the end of the locking plate 29 is fixedly connected with a spring 2 30, the end of the spring 2 30 is fixedly connected to the inner wall of the locking plate 1 27, and the surface of the locking plate 29 is in contact with the tooth groove of the ratchet gear 26.

[0080] The second locking plate 29 is engaged with the second locking plate 29, and the second locking plate 29 is engaged with the second locking plate 29, so that the ratchet gear 26 is locked.

[0081] When the hemostatic pressure needs to be released, the locking plate 1 27 needs to be pressed, so that the locking plate 1 27 compresses the spring 1 28, thereby synchronously driving the locking plate 29 to move through the displacement of the locking plate 1 27 until the locking plate 29 is disengaged from the ratchet gear 26. At this time, the ratchet gear 26 is no longer restricted, and the hemostatic pressure can be smoothly released.

[0082] It is worth noting that there are two sets of locking parts. Therefore, when releasing the hemostatic pressure, it is necessary to manually press the locking plates 27 on both sides with both hands. That is, in this way, when releasing the pressure and removing the equipment, the personnel are forced to use both hands, which makes the removal process smoother and more conducive to the patient's recovery, and avoids the situation where some people relax their vigilance after the rescue is completed and remove the equipment with one hand, which may touch the wound.

[0083] Furthermore, the surfaces of the two locking plates 27 are fixedly connected with pressing blocks 34, and the surfaces of the two pressing blocks 34 are provided with anti-slip grooves. Therefore, through the setting of the two pressing blocks 34, when a person presses the two pressing blocks 34 at the same time to release the locking state, there will be no slipping.

[0084] Working principle: When the medical emergency limb rescue hemostasis device is used, when a person's arm is bleeding and emergency hemostasis treatment is required, the device can be taken out, and the device body 1 and the device body 2 2 are clamped above the bleeding part of the limb, so that the position of the pressing plate 4 is the position of the blood vessel required for hemostasis and compression. At this time, by starting the driving element 31, the electromagnet 8 can be energized, thereby maintaining a firm connection between the device body 1 and the device body 2;

[0085] When the driving element 31 is started, the threaded rod 32 is synchronously driven to rotate, so that the pressing plate 4 is displaced at a relatively fast speed, and the limb area can be compressed and hemostatically treated quickly. At the same time, during this process, the two curved plates 7 follow the displacement and deflect at the same time. Therefore, through the cooperation between the two curved plates 7 and the pressing plate 4, the hemostatic compression on the patient's limb is more closely aligned with the curvature of the limb, so that the compression and hemostasis effect is better.

[0086] When the device is in use, the displacement state of the pressing rod 5 can be limited by the locking component, so that it cannot be easily reset, thereby ensuring the continuity of the hemostasis state and facilitating wound treatment by medical staff;

[0087] After completing the hemostatic first aid, when it is necessary to release the hemostatic pressure, the locking plates 27 on both sides are pressed by both hands at the same time to control the two locking components, and the threaded rod 32 is controlled to rotate in the opposite direction by the driving element 31.

[0088] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
