[0001] The present invention relates to the technical field of hemostasis in emergency, and specifically to an arterial compression hemostasis device for an emergency rescue center. Background Art

[0002] Application No. CN202410100868.2 discloses a limb arterial compression hemostasis device for first aid, including an upright plate, a fixing plate, a support plate, a joystick, a pressing plate, a wound pressing mechanism, a linkage assembly, a radian adjusting assembly, and a clamping mechanism; it solves the problem that when the body types of patients are different, the injured limbs of patients cannot be clamped by the upper arc plate and the lower arc plate; in addition, the diameters of the upper limbs and lower limbs of patients are also inconsistent, so the upper arc plate and the lower arc plate cannot be applied to the upper limbs and lower limbs of patients at the same time, there are limitations.

[0003] During the emergency rescue process, arterial rupture and bleeding is a life-threatening emergency that requires rapid and effective hemostasis measures. Currently, clinically, it mainly relies on medical staff to manually compress for hemostasis, and this method has significant defects: on the one hand, manual compression requires continuous application of force, which is likely to cause physical exhaustion of medical staff, and may affect the compression effect due to fatigue especially during long-term rescue; on the other hand, when manually stopping bleeding, medical staff cannot free their hands to perform other key treatment operations, such as establishing an intravenous access, drug injection, etc., delaying the overall rescue efficiency. In addition, although traditional tourniquets and the above-mentioned patent can fix and apply pressure, they lack functions of pressure adjustment and hemostasis state monitoring, and there is a risk of incomplete hemostasis or tissue damage caused by excessive compression. Therefore, there is an urgent need for a device that can replace manual compression, achieve precise and controllable compression hemostasis, and have a function of feedback on the hemostasis effect.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1.

[0019] 2. For the arterial compression hemostasis device used in the emergency rescue center, through the use of a silicone transparent hemostasis ball, blood drainage grooves and blood collection cotton to form a multi-layer monitoring system. When the contact area of the hemostasis ball is gradually reduced by rotating the adjusting rod, if the blood collection cotton continues to turn red after the blood drainage grooves are exposed, it can be intuitively judged that the hemostasis is incomplete, avoiding secondary massive bleeding caused by directly removing the pressure; at the same time, the silicone material hemostasis ball can evenly disperse the pressure and reduce the risk of local tissue damage.

[0020] 3. For the arterial compression hemostasis device used in the emergency rescue center, through the customized specification design, the hemostasis member, the pressing member and the tightening member can be adapted to different thicknesses of limbs or necks. With the elastic compensation of the elastic band in the pre-tightening member, it is ensured that the pressure application process can effectively stop bleeding and avoid excessive compression; the progressive lifting function of the adjusting rod realizes the fine control of the hemostasis pressure and ensures the safety of the pressure removal process.

[0021] 4. For the arterial compression hemostasis device used in the emergency rescue center, through the modular design integrating the functions of hemostasis, pressure application and fixation, only by aligning the bleeding point, winding the winding tape tightly and locking the pre-tightening pin can the hemostasis work be completed during operation, greatly shortening the rescue preparation time; the blood collection sleeve and the blood collection cotton can collect the oozing blood, reduce the blood pollution of the surgical area, maintain the cleanliness of the surgical environment and create favorable conditions for subsequent treatment.

[0040] Please refer to Figures 1-10 As shown, the present invention provides an arterial compression hemostasis device for an emergency rescue center, including a hemostasis member 100 for contacting the arterial bleeding site, a pressing member 200 for elastically pressing on the hemostasis member 100 to stop bleeding, and a pair of tightening members 300 for binding the pressing member 200 to the limbs or neck; so that there is no need for medical staff to press with their hands during rescue hemostasis, thus freeing up their hands for rescue treatment.

[0041] Specifically, the hemostatic member 100 includes a hemostatic ball 110, a blood collection sleeve 120 for guiding the axial movement of the hemostatic ball 110, and an adjusting rod 140 for driving the hemostatic ball 110 to move within the cavity of the blood collection sleeve 120; a blood collection cotton 130 is embedded inside the blood collection sleeve 120, the hemostatic ball 110 is a silica gel transparent hemisphere, and a plurality of blood guiding grooves 111 are formed on its outer side surface; by manipulating the adjusting rod 140 to lift the hemostatic ball 110 and gradually reduce the contact area with the skin, until the blood guiding grooves 111 are exposed, if the bleeding site has not been stopped bleeding, then observe the redness of the blood collection cotton 130. If it continues to turn red, it indicates that the hemostasis is not in place, and then continuous pressure should be applied to stop bleeding, avoiding directly exposing the arterial bleeding site and a large amount of blood oozing, and also ensuring a clean surgical environment.

[0042] Further, the lower end opening of the blood guiding groove 111 is far from the bottom center of the hemostatic ball 110, ensuring that the hemostatic ball 110 has a complete surface for compressing the bleeding site to stop bleeding; the blood collection sleeve 120 is in a cylindrical shape, and a blood collection cavity 121 is formed on its top end surface. The blood collection cavity 121 extends above the bottom of the blood collection sleeve 120, and a plurality of blood collection ports 122 are arranged at equal intervals in a ring shape on the bottom surface of the blood collection cavity 121 for introducing the blood oozing from the blood guiding grooves 111, so that the blood collection cotton 130 can collect the blood, and at the same time, the bleeding situation is judged through the red state of the blood collection cotton 130.

[0043] The blood collection cotton 130 is sleeved inside the blood collection cavity 121 for easy disassembly and use. It can be taken out for cleaning and replacement; a plurality of protrusions 131 are arranged at equal intervals in a ring shape on the bottom surface of the blood collection cotton 130, and the plurality of protrusions 131 are correspondingly clamped and matched with the plurality of blood collection ports 122.

[0044] Further, in order to position the hemostatic ball 110 relative to the blood collection sleeve 120, a threaded wall 124 is formed on the inner wall of the top of the blood collection sleeve 120. The top center of the hemostatic ball 110 is embedded with an adjusting rod 140. The bottom end of the adjusting rod 140 is limited by a hollow shell and sleeved on the top surface of the hemostatic ball 110, and can rotate freely and drive the hemostatic ball 110 to move axially; a threaded ring 141 that is threadedly connected to the threaded wall 124 is sleeved on the top end of the adjusting rod 140. By rotating the threaded ring 141, the hemostatic ball 110 is driven to move axially to adjust the hemostatic skin contact area.

[0045] Specifically, such as Figures 7-11As shown in the figure, the pressing member 200 includes a pressing cylinder 210 for elastically pressing the blood collection sleeve 120, and a pressing belt sleeve 230 sleeved on the outer wall of the pressing cylinder 210 and used to limit the pair of tightening members 300 from tightly pulling the pressing cylinder 210; the tightening members 300 include a winding belt 310 limit-connected to the pressing belt sleeve 230 and a pre-tightening member 320 sleeved on the outer end of the winding belt 310; a number of through holes 311 are equidistantly arranged on the long median line of the top surface of the winding belt 310, and the pre-tightening member 320 includes a pre-tightening sleeve 321 sleeved on the end of the winding belt 310, an elastic band 322 hooked between the end of the winding belt 310 and the inside of the pre-tightening sleeve 321, and a pre-tightening pin 323 threadedly connected to the top surface inside the pre-tightening sleeve 321; after winding a pair of winding belts 310 around the limbs or neck, the exposed pre-tightening sleeve 321 is pulled out and the pre-tightening pin 323 is screwed out into the through hole 311, and the tightening pressing member 200 presses the hemostatic member 100 to compress and stop bleeding. Among them, the hemostatic member 100, the pressing member 200, and the tightening member 300 are customized and matched with corresponding specifications according to the thickness of the limbs and neck for ready use.

[0046] Further, the top surface of the pressing cylinder 210 is open and sleeved and slid with the blood collection sleeve 120. An annular platform 123 sleeved and slid with the inner wall of the pressing cylinder 210 is provided on the outer wall of the middle part of the blood collection sleeve 120. A compression spring 220 is arranged between the top of the pressing cylinder 210 and the annular platform 123. The blood collection sleeve 120 is elastically pressed by the compression spring 220 to drive the hemostatic ball 110 to compress the arterial bleeding site.

[0047] A double pressing ring 211 for clamping the winding belt 310 is provided on the outer wall of the bottom of the pressing cylinder 210. A number of pairs of jacks 212 are equidistantly arranged in a ring shape on the top surface of the double pressing ring 211. A number of pairs of pressing blocks 231 corresponding to the number of pairs of jacks 212 are provided on the bottom surface of the pressing belt sleeve 230. A bayonet 312 inserted with the pressing block 231 is provided on the top surface of one end of the winding belt 310; so that the winding belt 310 can be disassembled and used to temporarily replace the length of the winding belt 310 to match the limbs for winding and fixing.

[0048] Further, the longitudinal section of the pressing belt sleeve 230 is L-shaped and a spring 232 is provided on the top surface of its vertical section. A threaded sleeve 233 is provided on the top surface of the spring 232. An external thread 213 threadedly connected to the threaded sleeve 233 is provided on the outer wall of the top of the pressing belt sleeve 230; the height is adjusted by the threaded sleeve 233 to control the elastic force of the spring 232, so that the pressing belt sleeve 230 stably limits the winding belt 310 inside the double pressing ring 211.

[0049] A protective layer 234 is bonded between the threaded sleeve 233 and the vertical section of the pressing belt sleeve 230. The protective layer 234 is made of a soft material, preferably silica gel or leather; the protective layer 234 is used to block the spring 232, playing a role in protection and aesthetics; a sealing sleeve 240 is sleeved on the bottom of the pressing cylinder 210. The sealing sleeve 240 is made of a water-absorbing material, preferably water-absorbing resin or water-absorbing sponge, for collecting the overflowing blood.

[0050] In addition, the winding tape 310 is made of stainless steel into a long sheet shape with its top surface being a concave arc surface. A soft plastic layer is wrapped around the outside of the winding tape 310 to play a role in skin care. When the winding tape 310 is pressed on the limbs or neck, it will deform itself to form a winding state. A sleeve 330 connected to the pre-tightening pin 323 is sleeved in the through hole 311, thereby increasing the area of fixation between the pre-tightening pin 323 and the winding tape 310.

[0051] A tape hole 313 is formed at the other end of the winding tape 310. One end of the elastic band 322 bypasses the tape hole 313 and is bonded, and the other end is placed inside the pre-tightening sleeve 321 and positioned by a pin. A fixing sleeve 3211 is nested near the outer end of the top surface of the pre-tightening sleeve 321. The pre-tightening pin 323 is threadedly connected to both the fixing sleeve 3211 and the sleeve 330, thereby positioning the position of the pre-tightening sleeve 321, so that the pulled-out pre-tightening sleeve 321 pulls the winding tape 310 to tighten, achieving the function of adjusting the tightening degree of the winding tape 310 and stabilizing the tightened state of the winding tape 310.

[0052] When the arterial compression hemostasis device for the emergency rescue center of the present invention is in use, the hemostatic ball 110 is aligned with the arterial bleeding site and pressed. Then, a pair of winding tapes 310 are wound around the outside of the limbs or neck. By pulling out the exposed pre-tightening sleeve 321 and screwing out the pre-tightening pin 323 into the through hole 311, the position of the pre-tightening sleeve 321 is threadedly connected and positioned with the sleeve 330, thereby tightening the pressing member 200 to press the hemostatic member 100 for hemostasis; instead of manually pressing the blood, freeing up the hands for rescue and treatment work;

[0053] Before removing the hemostatic ball 110, the hemostatic ball 110 is lifted by rotating the adjusting rod 140 to slowly reduce the contact area with the skin. When the blood guiding groove 111 is exposed, if the bleeding site has not been hemostatic yet, observe the situation of the blood collecting cotton 130 turning red. If it continues to turn red, it indicates that the hemostasis is not in place, and then continue to press for hemostasis, avoiding directly exposing the arterial bleeding site and a large amount of blood oozing, and also ensuring a clean surgical environment.

[0054] It should be noted that the above embodiments are only for explaining the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
