Description

Technical Field

[0001] The invention belongs to the technical field of emergency department nursing appliances, and in particular relates to a rapid hemostasis auxiliary device for emergency department nursing. Background Art

[0002] Hemostasis is the process of stopping the blood from flowing outwards by certain means. The effect of hemostasis varies from person to person, some are fast, some are slow, and it is related to platelets. 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 and is the result of the interaction of multiple factors and mechanisms. The hemostasis process mainly includes three processes: vasoconstriction, platelet thrombosis and blood coagulation.

[0003] In the prior art (publication number CN216985014U, patent name is a patent application for a rapid hemostasis auxiliary device for emergency department nursing), blood vessels can be quickly pressed to stop bleeding, and the hemostasis effect is good; wherein, air bags are installed on the inner sides of the first arc block and the second arc block respectively, and the hemostasis is performed by the air bags, which will not damage the blood vessels, and the hemostasis effect is good and the hemostasis time is long. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art:

[0004] When emergency doctors are trying to stop bleeding from a patient's affected limb, they mostly use hemostatic forceps with hemostatic cotton to clamp the patient to stop bleeding. Although this can achieve the purpose of stopping bleeding, the medical staff still needs to hold the hemostatic forceps for a long time. When the patient moves or the medical staff is tired and exhausted, the hemostatic forceps may become loose and the affected limb may still bleed. If the medical staff clamps the hemostatic forceps too tightly, it may cause secondary damage to the affected limb. Summary of the invention

DETAILED DESCRIPTION

[0048] The present invention is specifically described below in conjunction with the accompanying drawings and specific embodiments:

[0049] like Figure 1-Figure 15 As shown, a rapid hemostasis auxiliary device for emergency department nursing of the present invention comprises a base frame 1, both sides of the base frame 1 are fixedly connected with handles 2, and the end of the handle 2 away from the base frame 1 is fixedly connected with a side tube 3.

[0050] Both sides of the base frame 1 are provided with an adjustment component 4 and a hemostasis component 5 for hemostasis of the affected part. The adjustment component 4 includes a micro motor 41 fixed at the top center of the base frame 1 and used as a unified driving source.

The positioning frame adopts an elastic pressing method to provide effective and rapid hemostasis care for the affected limb to avoid bleeding caused by inadequate hemostasis. A contraction component 6 is provided on the side tube 3. The contraction component 6 is used to contract the tourniquet 65 tied to the affected limb to cut off the blood supply. The tourniquet 65 uses a widened and thickened design to tie the veins of the affected limb to cut off the blood supply. The veins of the affected limb are temporarily tied to cut off the blood supply, which is conducive to rapid hemostasis care of the affected limb.

[0051] like Figure 4-Figure 11As shown, the adjustment component 4 also includes a micro-electric push rod 42 embedded in an output shaft of the micro-motor 41, the piston rod of the micro-electric push rod 42 is fixedly connected to a driving bevel gear 43, and a main bevel gear 44 is arranged below the driving bevel gear 43.

[0052] The hemostatic assembly 5 comprises a curved arm 51 fixed at the bottom of the threaded sleeve 46, a side of the curved arm 51 away from the threaded sleeve 46 is slidably connected with a polished rod 52, the outer surface of the polished rod 52 is sleeved with a spring 53 fixed to the curved arm 51, and the inner side of the polished rod 52 is fixedly connected to a positioning frame 54. The two groups of threaded sleeves 46 drive the two groups of positioning frames 54 to synchronously achieve the synchronous internal and external displacement adjustment effect through the polished rods 52 on the two curved arms 51, and the inner side of the positioning frame 54 is adhered with a Velcro 55, and the Velcro 55 and the hemostatic pad 56 are also connected by adhesion. The two springs 53 play an elastic buffering role on the displacement spacing of the two groups of positioning frames 54, and the two groups of Velcro 55 play a fast bonding role on the two groups of positioning frames 54 and the hemostatic pad 56, which is conducive to the rapid replacement of the hemostatic pad 56, thereby adopting an elastic pressing method to effectively and quickly stop bleeding for the affected limb, so as to avoid bleeding caused by inadequate hemostatic action.

[0053] The front and rear sides of the bottom of the base frame 1 are provided with through grooves 10 that slide with the curved arm 51, which play the role of sliding support for the curved arm 51 and improve the displacement stability of the curved arm 51. The positioning frame 54, Velcro 55 and hemostatic pad 56 are designed in an arc shape to press and stop bleeding to the affected limb in the maximum range. The four corners of the positioning frame 54, Velcro 55 and hemostatic pad 56 are chamfered to prevent the positioning frame 54, Velcro 55 and hemostatic pad 56 from causing skin scratches during bleeding of the affected limb, and the hemostatic pad 56 is made of a medicine core coated with hemostatic liquid to effectively stop bleeding of the affected limb.

[0054] The contraction assembly 6 includes auxiliary bevel gears 61 meshed on both sides of the main bevel gear 44. The two sets of auxiliary bevel gears 61 are driven to rotate by the driving bevel gear 43 and the main bevel gear 44 after being meshed in place, and the inner cavity of the auxiliary bevel gear 61 is fixedly connected with a rotating rod 62. The end of the rotating rod 62 away from the auxiliary bevel gear 61 is fixedly connected with a circular gear 63 that rotates with the side tube 3. The two sets of auxiliary bevel gears 61 drive the two sets of circular gears 63 to rotate accordingly through the two rotating rods 62, and the circular gears 63 The outer side of the side tube 3 is diagonally meshed with convex teeth 64 integrally formed with the tourniquet 65, and the outer side of the side tube 3 is fixedly connected to a limiting roller 66 that cooperates with the tourniquet 65 for transmission. The two groups of circular gears 63 drive the two tourniquets 65 to be rolled up through the two groups of convex teeth 64, and the limiting roller 66 plays a role in closing the two tourniquets 65. Under the transmission cooperation, the veins of the affected limb are temporarily tied up to cut off the blood supply, which is beneficial for the hemostatic pads 56 on the two groups of positioning frames 54 to quickly stop bleeding for the affected limb.

[0055] The convex teeth 64 are distributed in an array along the tourniquet 65, and the end of the tourniquet 65 away from the convex teeth 64 is fixedly connected to the side tube 3, and the other end of the tourniquet 65 is meshed with the circular gear 63 through the convex teeth 64 for transmission, so that the circular gear 63 can drive the tourniquet 65 to be wound or released through the convex teeth 64, and the blood supply to the upper and lower veins of the affected limb can be suspended. The inner wall of the tourniquet 65 is fixedly connected with a silicone layer 11, and the silicone layer 11 adopts a ring design, and both ends of the silicone layer 11 are provided with arc angles, which improves the comfort of binding between the tourniquet 65 and the affected limb, and also plays a role of flexible protection. An anti-slip head 12 is integrally formed at one end of the tourniquet 65 close to the convex teeth 64, which prevents the end of the tourniquet 65 with the convex teeth from slipping off, and a winding box 13 that slides with the anti-slip head 12 and the tourniquet 65 is fixed diagonally to the top of the side tube 3, which serves to store the end of the tourniquet 65 with the convex teeth. The limiting rollers 66 are distributed in an axially symmetrical state along the central axis of the tourniquet 65, and both sides of the limiting rollers 66 are fixedly connected with limiting disks that cooperate with the tourniquet 65 to prevent slipping off, which prevents the tourniquet 65 from slipping off and enables the tourniquet 65 to more effectively suspend blood supply to the veins in the upper and lower parts of the affected limb.

[0056] like Figure 12-14 As shown, during the hemostasis of the affected limb, in addition to pressing to stop bleeding, cold compress is also effective, and the hemostasis means currently used cannot perform cold compress hemostasis care on the affected limb based on pressing to stop bleeding. Sealing covers 7 are provided on both sides of the top of the base frame 1, and the sealing cover 7 is connected to the cooling assembly 8 and the cold compress assembly 9 used in conjunction with the hemostasis assembly 5. The cooling assembly 8 includes a micro refrigerator 81 fixed on the top of the base frame 1, and the top of the micro refrigerator 81 is connected to a cold supply tee pipe 82 connected to the sealing cover 7. The cold source is supplied by two groups of micro refrigerators 81, and the cold source is supplied to the two groups of sealing covers 7 by two cold supply tees 82.

[0057] A main synchronous wheel 83 is fixedly connected to the other output shaft of the micro motor 41, and a slave synchronous wheel 84 is connected to the outer side of the main synchronous wheel 83 through a synchronous belt transmission. The inner cavity of the slave synchronous wheel 84 is fixedly connected to an impeller 85 arranged in the sealing cover 7 through a fan shaft, and a cold exhaust manifold 86 is connected to the bottom of the sealing cover 7. The main synchronous wheel 83 on the micro motor 41 drives the two sets of slave synchronous wheels 84 to rotate synchronously through the synchronous belt, and the two sets of slave synchronous wheels 84 drive the two sets of impellers 85 to rotate in the two sets of sealing covers 7, and discharge the cold source supplied to the two sets of sealing covers 7 into the two cold exhaust manifolds 86.

[0058] The cold compress assembly 9 includes a three-way valve 91 connected to the bottom end of the cold exhaust manifold 86, and a temperature sensor 92 is embedded in the bottom end of the three-way valve 91, both ends of the three-way valve 91 are connected with a telescopic tube 93, and the end of the telescopic tube 93 away from the three-way valve 91 is connected with a pressurizing tube 94, the bottom end of the pressurizing tube 94 is connected with a cold supply hood 95 connected and coordinated with the positioning frame 54, and both sides of the positioning frame 54 and the Velcro 55 are provided with reserved windows 96 connected and coordinated with the cold supply hood 95, the cold source in the two cold exhaust manifolds 86 is then supplied into the cold supply hood 95 in turn by the telescopic tubes 93 and the pressurizing tube 94 on the two groups of three-way valves 91, and then passes through the reserved windows 96 on the positioning frame 54 and the Velcro 55 to reach the area of ​​the two hemostatic pads 56, so as to cool the hemostatic pads 56 in the pressed hemostatic state, and also play a role in assisting cold compress hemostasis for the affected limb.

[0059] Working principle of a rapid hemostasis auxiliary device for emergency department nursing:

[0060] First, two new hemostatic pads 56 are adhered to the two sets of positioning frames 54 through Velcro 55 ; then the affected limb is passed through the silicone layer 11 of the front and rear sets of hemostatic bands 65 and placed on the inner side of the two sets of positioning frames 54 .

[0061] First, the micro electric push rod 42 is controlled to open and drive the driving bevel gear 43 to move down to the meshing part of the main bevel gear 44, and then the micro motor 41 is controlled to open and drive the main bevel gear 44 to rotate through the driving bevel gear 43 that is meshed in place, and the main bevel gear 44 drives the forward and reverse threaded rods 45 to rotate forwardly, and the forward and reverse threaded rods 45 drive the two sets of threaded sleeves 46 to move inward synchronously.

[0062] The two groups of threaded sleeves 46 drive the two groups of curved arms 51 to slide synchronously inward in the two groups of through grooves 10. The two groups of curved arms 51 also drive the two groups of positioning frames 54 to be attached to the hemostasis area of ​​the affected limb through the two light rods 52. At the same time, the two groups of positioning frames 54 are subjected to the outward reaction force of the affected limb, forcing the two light rods 52 to slide outward in the two groups of positioning frames 54, and the two springs 53 elastically buffer the two outward sliding light rods 52 until the hemostatic pads 56 in the two groups of positioning frames 54 are effectively pressed and attached to the bleeding points of the patient, thereby completing the compression hemostasis care of the affected limb.

[0063] When the driving bevel gear 43 drives the main bevel gear 44 to rotate, the main bevel gear 44 also drives the two sets of auxiliary bevel gears 61 to rotate. The two sets of auxiliary bevel gears 61 drive the two sets of circular gears 63 to rotate toward each other through the two rotating rods 62. Since the ends of the two tourniquets 65 without teeth are fixedly connected to the two sets of side tubes 3, the two sets of limiting rollers 66 play a role in the closing transmission of the two tourniquets 65, so that the two sets of circular gears 63 drive the ends of the two tourniquets 65 with teeth to be rolled up through the two sets of convex teeth 64. As the two tourniquets 65 are gradually rolled up, the length becomes shorter, and then the upper and lower veins of the affected limb are tied tightly through the two sets of silicone layers 11, which can temporarily stop the upper and lower veins of the affected limb from supplying blood to the bleeding point.

[0064] At the same time, the two groups of micro-refrigerators 81 are controlled to be turned on in advance and the generated cold source is supplied into the two groups of sealed covers 7 through the two cold supply tees 82, and the micro-electric push rod 42 is controlled to drive the driving bevel gear 43 to move up and disengage the meshing portion of the main bevel gear 44; then the micro-motor 41 is controlled to drive the main synchronous wheel 83 to rotate, and the main synchronous wheel 83 drives the two groups of impellers 85 on the synchronous wheels 84 to rotate synchronously in the two groups of sealed covers 7 through the synchronous belt, and the two groups of impellers 85 in the rotating state supply the cold source in the two groups of sealed covers 7 into the two cold exhaust manifolds 86. The temperature of the cold source is then monitored in real time through the temperature sensors 92 on the two sets of open three-way valves 91. The two cold sources pass through the telescopic tubes 93 and the pressurized tubes 94 on the two sets of three-way valves 91 in turn to reach the cold supply hoods 95 on the two sets of positioning frames 54, and pass through the reserved windows 96 on the positioning frames 54 and the Velcro 55 to reach the areas of the two hemostatic pads 56, so as to cool the hemostatic pads 56 in the pressed hemostatic state and provide cold compress hemostatic care for the affected limb.

[0065] It should be noted that the specific models and specifications of the micro motor 41, the micro electric push rod 42 and the micro refrigerator 81 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0066] The power supply circuits of the micro motor 41 , the micro electric push rod 42 and the micro refrigerator 81 are clear to those skilled in the art and will not be described in detail herein.
