Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an automatic hemostasis and pressurization device for limbs. Background Art

[0002] Pressure hemostasis refers to the use of external pressure to force the blood vessels at the mouth and wound to close, blocking blood outflow, allowing the wound to have enough time to form a blood clot and achieve the purpose of hemostasis. This method is suitable for bleeding from veins, arterioles, and capillaries, such as bleeding in the upper and lower limbs, elbows, knees, etc.

[0003] Most of the existing pressurized hemostasis methods use elastic bands to compress and stop bleeding. Or medical staff manually compress and stop bleeding. Although both can achieve hemostasis operations, in actual operations, the elastic tourniquet will cause a certain amount of compression on the skin near the patient's wound, and the pressure is uncontrollable, which is very likely to have a negative impact on the patient's wound, and further cause secondary damage to the patient's wound. Secondly, although medical staff can control the pressing force manually, which has a good pressing and hemostasis effect, it wastes the manpower of medical staff, and when there are many patients, enough medical staff are needed to press on each patient separately, which is extremely inconvenient, and there may be a shortage of medical staff, resulting in delayed treatment of patients.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

They are all fixedly connected with curved panels 7, a fixed plate 8 is fixedly connected between the two curved panels 7, a movable plate 19 is arranged at the bottom of the fixed plate 8, an inclined plate 15 is fixedly connected at the bottom of the movable plate 19 near the front and rear sides, a pressing pad 16 is bonded and installed between the two inclined plates 15, a threaded rod 18 is threadedly connected through the fixed plate 8, the bottom end of the threaded rod 18 passes through the movable plate 19 and is movably connected to the movable plate 19, a stopper 28 is fixedly connected to the bottom end of the threaded rod 18, a torsion block 20 is fixedly connected to the top of the threaded rod 18, and a clamping mechanism is arranged on the top of the torsion block 20.

[0030] See also Figure 2 and Figure 4 The positioning mechanism includes two round shells 9, which are respectively inserted into the top of the round sleeve 6 near the left and right sides, and the tops of the two round shells 9 are provided with handles 10, and the bottoms of the two handles 10 are fixedly connected with round rods 11, the bottom ends of the two round rods 11 pass through the top of the round shell 9 and are movably connected to the top of the round shell 9, and the bottom ends of the two round rods 11 are fixedly connected with round blocks 12, and the two connecting rods 5 are provided with a plurality of round holes 14, the bottoms of the round blocks 12 are inserted into the corresponding inner cavities of the round holes 14, and the top of the round blocks 12 is fixedly connected with a No. 1 spring 13, the No. 1 spring 13 is movably sleeved on the outside of the round rod 11, and the top of the No. 1 spring 13 is fixedly connected to the top of the inner wall of the round shell 9.

[0031] This setting can realize the plug-in and positioning operation between the connecting rod 5 and the circular sleeve 6, and the distance between the two clamping sleeves 1 can be conveniently adjusted. It can be suitable for different practical scenarios. For example, if the patient's limb joints are injured, the two clamping sleeves 1 can be respectively clamped on both sides of the joints, and multiple connecting rods 5 can be used to achieve alternative fixation of the patient's limbs, which can avoid joint bending and cause secondary injury.

[0032] See also Figure 6 , Figure 7 and Figure 8The clamping mechanism includes a top plate 26, and a plurality of connecting strips 24 are movably connected to the outer side of the top plate 26. A plurality of through grooves 37 are provided on the fixed plate 8. The bottoms of the plurality of connecting strips 24 respectively penetrate the corresponding through grooves 37 and are fixedly connected to the top of the movable plate 19. A positioning groove 27 matching the torsion block 20 is provided on the bottom of the top plate 26, and a plurality of side plates 29 are fixedly connected to the top of the top plate 26. The bottom of the side plate 29 extends to the outer side of the top plate 26, and an insert block 30 is slidably connected to the bottom of the side plate 29. An anti-slip pad 33 is fixedly installed on the top of the insert block 30 near the edge, and a clamping block 25 is provided at the bottom of the insert block 30, and the clamping block 25 is fixedly connected to the corresponding connecting strip 24 at the top inclined surface.

[0033] This arrangement can realize the clamping and positioning of the torsion block 20 at the top of the threaded rod 18, and further realize the positioning of the threaded rod 18, which can prevent the threaded rod 18 from loosening or rotating due to external force, resulting in an increase or decrease in the compression force on the patient. If the compression force is reduced, blood may flow out, and if the compression force is increased, excessive compression may occur, causing the risk of secondary injury.

[0034] See also Figure 8 A plurality of limit grooves 35 are provided on the outside of the top plate 26, and the inner cavities of the plurality of limit grooves 35 are slidably connected to the limit blocks 34. The outer sides of the limit blocks 34 are fixedly connected to the outer walls of the corresponding connecting strips 24, and a No. 2 spring 36 is fixedly connected between the top of the limit block 34 and the top of the inner wall of the limit groove 35.

[0035] Through this setting, the movement of the top plate 26 is limited, so that the top plate 26 can move up and down at will, and the setting of the No. 2 spring 36 can provide a certain support effect on the top plate 26 to prevent the top plate 26 from falling.

[0036] See also Figure 8 A slide groove 31 is fixedly connected to the top of the insert block 30 , a slider 32 is slidably connected to the inner cavity of the slide groove 31 , and the top of the slider 32 is fixedly connected to the bottom of the side plate 29 .

[0037] This arrangement realizes the limiting operation between the insert block 30 and the side plate 29, so that the insert block 30 can slide to the clamping block 25 for clamping, and is affected by the No. 2 spring 36, making the clamping more secure.

[0038] See also Figure 1 The inner wall of the ferrule 1 is fixedly connected with a rubber column 4 near the front and rear sides, and the top of the ferrule 1 is set in an arc surface.

[0039] The two rubber columns 4 are provided to facilitate the positioning of the ferrule 1 between the patient's limbs, that is, the rubber columns 4 are in contact with the patient's skin tissue to increase friction and further improve the fixing effect.

[0040] See also Figure 3 Two adhesive tapes 17 are fixedly connected to the pressing pad 16 , and the two adhesive tapes 17 are respectively adhered to the corresponding inclined plates 15 .

[0041] This arrangement allows the compression pad 16 to be easily disassembled, cleaned, and disinfected later.

[0042] See also Figure 3 and Figure 5 A plurality of limiting cylinders 23 are fixedly connected to the top of the movable plate 19, and limiting rods 22 are slidably inserted into the inner cavities of the plurality of limiting cylinders 23. The top end of the limiting rod 22 extends to the top of the limiting cylinder 23 and is fixedly connected to a top block 21, which is fixedly connected to the bottom of the fixed plate 8.

[0043] Through this arrangement, when the threaded rod 18 pushes the movable plate 19 to move, the movable plate 19 also drives the top multiple limiting cylinders 23 to move together. The cooperation between the limiting cylinders 23 and the limiting rods 22 further improves the stability of the movable plate 19 when moving up and down.

[0044] Working principle: When the present invention is used, the specific location of the wound of the patient is first confirmed, and it is determined whether there is trauma on the patient's joint. If there is trauma, the two handles 10 are pulled upward, so that the two handles 10 respectively drive the round rod 11 to move upward, and the round rod 11 drives the round block 12 to withdraw from the corresponding round hole 14. At the same time, the round block 12 compresses the No. 1 spring 13. At this time, the two ferrules 1 can be relatively moved. When the distance between the two ferrules 1 is sufficient, the handle 10 is released, so that the handle 10 drives the corresponding No. 1 spring 13 to move upward. The round block 12 is reinserted into the corresponding round hole 14 to complete the fixation between the round sleeve 6 and the two connecting rods 5, and further realize the fixation between the two ferrules 1. Then, the two ferrules 1 are respectively clamped on the patient's limbs, so that the patient's injured joints and the wound to be hemostatic are between the two ferrules 1, and the wound is located directly below the pressing pad 16. Then, the two straps 2 and the Velcro 3 are used to fix the ferrule 1 and the patient's limbs. Then, the torsion block 20 can be toggled so that the torsion block 20 drives the threaded rod 18 to rotate, and the threaded rod 18 rotates downward. The movable plate 19 is pushed downward while the movable plate 19 drives the two bottom inclined plates 15 to move downward, and the two inclined plates 15 jointly drive the bottom pressing pad 16 to move downward, and the pressing pad 16 is used to press the patient's wound to stop bleeding. In the pressing process, the patient's feelings can be asked in real time, and the threaded rod 18 can be stopped from rotating after the patient is compressed to a certain degree, so as to avoid excessive compression and secondary damage to the patient's wound. At the same time, during the movement of the movable plate 19, the multiple connecting strips 24 at the top are also driven to move downward together, so that The multiple connecting strips 24 jointly drive the top plate 26 to move downward. When the threaded rod 18 does not need to rotate, the top plate 26 can be pressed upward so that the positioning groove 27 at the bottom of the top plate 26 is clamped on the outside of the twist block 20. At the same time, the multiple plug-in blocks 30 on the outside of the top plate 26 are moved so that the plug-in blocks 30 and the anti-slip pads 33 are clamped together inside the clamping block 25 to achieve the positioning of the top plate 26. By fixing the top plate 26, it is possible to prevent the threaded rod 18 from loosening in the later stage, resulting in compression loosening, and then causing blood to flow out of the patient's wound, thereby ensuring the compression effect.

[0045] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
