Description

Technical Field

[0001] This invention relates to the field of tourniquet technology, specifically to a femoral artery compression hemostasis device. Background Technology

[0002] Arterial hemostasis techniques commonly include mechanical compression hemostasis, invasive suture hemostasis, and hemostasis using drugs that utilize the blood's own coagulation properties. Currently, mechanical compression devices remain the most widely used basic approach in clinical practice due to their reliability, versatility, and low cost.

[0003] Effective arterial hemostasis requires the patient to remain in a completely supine position for an extended period of time, with the lower limb on the puncture side kept straight and immobilized, usually for 4-6 hours. This immobility is extremely painful for many patients, such as those with lower back pain, agitated individuals, and the elderly, making it difficult to coordinate with the working characteristics of common compression hemostasis devices and thus failing to achieve good hemostasis.

[0004] Therefore, a femoral artery compression hemostasis device is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a femoral artery compression hemostasis device, which has advantages and solves the problem.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a femoral artery compression hemostasis device, comprising two sets of straps evenly wound around both sides of a roller, with gauze wound in the middle of the roller. A winding assembly and a pressure pad are provided between the two straps. The winding assembly and pressure pad separate the two straps, and the winding assembly can wind up the two straps. An arc-shaped clamping plate is fixedly installed on the winding assembly. The rotation of the winding assembly winds up the two straps, tightening the pressure pad and gauze, and targeting the blood collection point for hemostasis. The pressure for hemostasis at the blood collection point comes from the straps surrounding the patient's leg, rather than from the pressure of an external instrument. This avoids the pressure effect on the blood collection point being affected by the patient's movement, ensuring that slight patient movement will not affect the compression hemostasis of the device, and avoiding discomfort caused by prolonged immobility of the patient.

[0007] Preferably, the connection point between the winding assembly and the strap is located at its end. The end of the winding assembly has a locking slot, and both ends of each strap can be simultaneously locked into a locking slot, forming a head-to-head connected structure set around the patient's blood collection point. When the winding assembly rotates, it can simultaneously wind up both ends of the strap to achieve a tightening effect. By rotating the winding assembly, the entire device can be fixed to the patient's leg while providing pressure support for the compression point.

[0008] Preferably, the winding assembly includes a positioning roller, a winding roller a, a winding roller b, and a torsion spring. The clamping plate is fixedly installed on the positioning roller. The connection structures between the winding assembly and the two side straps are the winding roller a and the winding roller b, respectively. The winding roller a and the winding roller b are rotatably connected to the positioning roller on both sides of the positioning roller. The two ends of the torsion spring are respectively connected to the positioning roller and the winding roller a.

[0009] Preferably, the positioning roller body is a connecting tube, the take-up roller a includes a roller a and a mandrel, and the take-up roller b includes a roller b and a connecting shaft. The mandrel and the connecting shaft are inserted into the connecting tube from both ends and are joined together inside it. The two take-up rollers are not a single integrated structure, so that the rollers on both sides can rotate independently to specifically take up the straps on both sides to better fit the human body structure.

[0010] Preferably, a guide cover is provided on each side of the connecting tube, and a pawl a is installed in each of the two guide covers. A ratchet a is provided between the spool a and the mandrel, which enters into the guide cover and engages with the pawl a. A ratchet b is provided between the spool b and the connecting shaft, which enters into the guide cover on the corresponding side and engages with the pawl a therein. The ratchet and pawl structure can limit the spool after winding to prevent loosening.

[0011] Preferably, a circular groove is formed at the end of the mandrel, and an inner ratchet is installed in the groove. A pawl b and a transmission wheel are provided at the end of the connecting shaft and inserted into the circular groove on the mandrel. One end of the pawl b is connected to the inner ratchet to form a ratchet and pawl mechanism, and the other end of the pawl b is engaged with a locking tooth on the transmission wheel, so that the rotation of the scroll a can drive the scroll b to rotate, and the scroll b can also rotate independently without driving the scroll a to rotate.

[0012] Preferably, another circular groove is provided at the end of the connecting shaft, and the pawl b is rotatably mounted on the annular end face of the end of the connecting shaft. The transmission wheel is inserted into the circular groove, and a rotating shaft and a spring are installed in the circular groove. The transmission wheel rotates around the axis of the rotating shaft and presses against the end of the circular groove on the mandrel by the action of the spring. Through the spring of the transmission wheel and the left and right sides of the torsion spring, the two rollers are pressed against each other to stabilize and cooperate with the pawls a on both sides.

[0013] Preferably, one side of the pressure pad is made of a hard plastic material, and the other side is made of a softer silicone material. After the strap is wrapped around, the softer silicone material is inside the annular structure. An air bladder is installed on the hard material of the pressure pad, and the air bladder is inflated and output to the softer side.

[0014] Preferably, the strap consists of an outer soft sheath and an inner hardened layer a. The soft sheath is filled with an adhesive strip of equal length to the strap. The gauze consists of a middle pouch and two hardened layers b on both sides. The structure of the hardened layer a is adapted to the hardened layer b and can be pressed and fastened onto the hardened layer b.

[0015] Preferably, the bag can be filled with iodine-soaked cotton and pressed and fixed by a pressure pad.

[0016] Compared with the prior art, the present invention provides a femoral artery compression hemostasis device, which has the following beneficial effects: 1. The rotation of the winding component winds up the straps on both sides, which tightens the pressure pad and gauze, targeting the blood collection point for hemostasis. The pressure for hemostasis at the blood collection point comes from the straps around the patient's leg, rather than from the pressure of external instruments. This avoids the pressure effect on the blood collection point being affected by the patient's movement. Slight movement of the patient will not affect the pressure hemostasis of this device, thus avoiding discomfort caused by the patient's inability to move for a long time. 2. The rigid plastic surface of the structural adhesive strip and pressure pad, as well as the winding assembly, distribute the pressure of the binding strap on both sides of the blood collection point during the binding process. This prevents the side with higher pressure from automatically winding towards the side with lower pressure during the winding process, which would cause pressure transfer to the blood collection point, poor hemostasis, and subsequent problems. 3. Place bandages on both sides of the blood collection point. When the bandages are tightened, they can exert some pressure on the artery, which can help stop the bleeding at the blood collection point. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a femoral artery compression hemostasis device.

[0021] In a typical embodiment of the femoral artery compression hemostasis device of this application, such as Figure 1-9 As shown, a femoral artery compression hemostasis device includes a bandage 1 and gauze 2. Both the bandage 1 and gauze 2 are wound on a roller. Two bandages 1 are wound on both sides of the gauze 2. A winding assembly 3 and a pressure pad 5 are installed between the two bandages 1. The winding assembly 3 and the pressure pad 5 separate the two bandages 1. The winding assembly 3 can wind up the two bandages 1. An arc-shaped clamping plate 4 is fixedly installed on the winding assembly 3. See details Figures 1 to 3As shown, the connection point between the winding assembly 3 and the bandage 1 is near its end. The end of the winding assembly 3 is provided with a locking slot, which can be connected to both ends of the bandage 1 simultaneously. By rotating, both ends of the bandage 1 can be wound up at the same time. The connection with both ends of the bandage 1 can form a ring structure. The tightness of the ring structure can be controlled by rotating the winding assembly 3. During the process of stopping bleeding at the femoral artery blood collection point, after the bandage 1 is wrapped around the root of the thigh, the winding assembly 3 is used to wind it up. This can provide pressure support for the pressure pad 5 of the compression hemostasis tool at the blood collection point. The two bandages 1 are arranged on the upper and lower sides of the blood collection point, and the pressure pad 5 is located between the two bandages 1. After moving to the blood collection point, the winding assembly 3 tightens the two bandages 1 at the same time, which can make the pressure pad 5 fit more tightly at the hemostasis point to stabilize the hemostasis effect.

[0022] For further details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the pressure pad 5 does not directly contact the hemostasis point. The gauze 2 wound on the roller is located inside the bandage 1 after the bandage 1 forms a ring structure, and is squeezed by the pressure pad 5, directly acting on the hemostasis point. The gauze 2 is mainly composed of the middle sleeve 21 and the hardened layers b22 on both sides. Iodine cotton can be filled in the sleeve 21 to stop bleeding at the blood collection point and disinfect at the same time. The bandage 1 is composed of the outer soft sleeve 11 and the inner hardened layer a13. The soft sleeve 11 is filled with an adhesive strip 12 of the same length as the bandage 1. The hardened layer a13 is structurally compatible with the hardened layer b22 and can be pressed on the hardened layer b22.

[0023] The bandage 1 needs to be set around the root of the thigh, while the gauze 2 only needs to cover the hemostasis point and requires a shorter length. By using the pressure pad 5 and pressing the hardened layer a13 onto the hardened layer b22, the bandage 1 can be specifically fixed to the blood collection point to avoid displacement during a longer hemostasis period.

[0024] Regarding the need to supplement the gauze 2 for hemostasis at the blood collection point, the pressure pad 5 covers the gauze 2 on the blood collection point. At this time, the hemostasis surface is large, while the arterial blood flow is large. The simple structure of the pressure pad 5 causes the pressure of the gauze 2 to be distributed across the entire covering surface, making it difficult to target the blood collection point for hemostasis. The pressure pad 5 is designed with a structure that connects end to end, and is arranged around the two side straps 1. A directional airbag is inserted into the pressure pad 5. When the airbag is inflated, it will output in the direction of the gauze 2. Before hemostasis, the position of the pressure pad 5 is adjusted so that the airbag is facing the blood collection point. When the airbag is inflated, the hemostasis at the blood collection point can be targeted. To prevent the airbag from shifting, the other side of the airbag can be fixed inside the pressure pad 5 on the side away from the gauze 2. The fixing side is made of hard plastic material, while the other side is made of softer silicone material.

[0025] For further details, please refer to [link / reference]. Figures 2 to 8 As shown, in actual use, since the patient's thigh size is not the same, but gradually increases from bottom to top, if the rotation of the winding component 3 is to simultaneously wind or release the two side straps 1, the strap 1 below the blood collection point cannot be tightened along with the upper strap 1. Since the upper strap 1 is tightened during the rotation of the winding component 3, the winding component 3 cannot continue to rotate, and therefore cannot continue to tighten the lower strap 1, causing the fixation of the pressure pad 5 to loosen to a certain extent. During a long period of hemostasis, it is impossible to ensure that hemostasis is continuously and effectively carried out.

[0026] To solve the aforementioned problems, a winding assembly 3 and a clamping plate 4 are provided. The winding assembly 3 includes a positioning roller 31, a winding roller a32, and a winding roller b33. The clamping plate 4 is fixedly installed on the positioning roller 31. At the same time, the arc-shaped inner surface of the clamping plate 4 is clamped at the patient's thigh, providing support for the entire winding assembly 3. The winding of the strap 1 by the winding assembly 3 is performed by the winding rollers a32 and b33 on both sides respectively.

[0027] Specifically, the positioning roller 31 is mainly a connecting tube 311, the take-up roller a32 includes a winding shaft a321 and a mandrel 323, and the take-up roller b33 includes a winding shaft b331 and a connecting shaft 333. The mandrel 323 on the take-up roller a32 and the connecting shaft 333 on the take-up roller b33 are inserted into the connecting tube 311 from both ends of the positioning roller 31 and are connected inside the connecting tube 311. The winding assembly 3 does not wind up the strap 1 in a single, synchronous manner. The winding rollers a32 and b33 on both sides wind up the strap 1 separately, so that after the upper strap 1 is wound up, the roller connected to the lower strap 1 can continue to rotate to wind up the lower strap 1.

[0028] Furthermore, each end of the connecting pipe 311 is provided with a guide cover 312. A pawl a313 is installed inside the guide cover 312. A ratchet a322 is installed between the spool a321 and the spindle 323, penetrating into the guide cover 312 and engaging with the pawl a313. Similarly, a ratchet b332 is installed between the spool b331 and the connecting shaft 333, penetrating into the corresponding guide cover 312 and engaging with the pawl a313 therein. A limit shaft 314 provides a rotatable connection between the pawl a313 and the guide cover 312, and a spring is also provided for elastic connection between the pawl a313 and the guide cover 312. Figure 6As shown, the rotation range of the pawl a313 is limited by the action of the limiting shaft 314. One of the limiting thresholds allows the pawl a313 to sink down to fully contact the teeth on the ratchet a322 and ratchet b332, and then it cannot sink further. At the same time, the spring ensures that the pawl a313 always rotates in the direction of full contact with the teeth on the ratchet b332 and maintains this state. The pawl a313 will only rotate when the ratchet a322 and ratchet b332 rotate, and after disengaging from the current tooth, it will fall directly into the next tooth. A torsion spring 34 is provided inside the connecting tube 311. The two ends of the torsion spring 34 are fixedly connected to the inner wall of the connecting tube 311 and the spindle 323, respectively. A circular groove is opened at the end of the spindle 323 so that the connecting shaft 333 can be embedded in the circular groove.

[0029] The guide cover 312 is thicker than both ratchet a322 and ratchet b332 on both sides, providing space for their axial movement within it. After the take-up rollers a32 and b33 rotate to take up the strap 1, the ratchet pawls cooperate to prevent them from resetting and rotating. This provides a movable space so that, in the event of hemostasis or excessively tight winding, the take-up rollers a32 and b33 can be pressed axially, causing ratchet a322 or b332 to disengage from the corresponding pawl a313. When the two can rotate, the winding strap 1 can be released. Since the connection between the pawl a313 and the guide cover 312 is provided with a limit shaft 314 and a spring, when the pawl a313 rotates to the limit point, it can engage with the corresponding tooth on the ratchet, so that the winding roller a32 and winding roller b33 can be reset to the state of being re-engaged with the corresponding pawl a313. The torsion spring 34 not only assists the winding shaft to reset and rotate, but also helps the two to reset to the state of being re-engaged with the pawl a313 after pressing the winding shaft.

[0030] In addition, see Figure 7 and Figure 8 The connection structure between take-up roller a32 and take-up roller b33 shown in the diagram has an inner ratchet 324 installed in the circular groove at the end of the mandrel 323. The part of the connecting shaft 333 inserted into the circular groove is provided with a pawl b334 and a drive wheel 335. The end of the connecting shaft 333 also has another circular groove. The pawl b334 is located on the annular end face of the end of the connecting shaft 333 and is rotatably connected to it. The drive wheel 335 is rotatably installed in the circular groove. Another spring is provided between the drive wheel 335 and the connecting shaft 333. The spring provides elastic support for the drive wheel 335 and also provides torsional support. The spring pushes the end of the drive wheel 335 to press against the end of the circular groove on the mandrel 323. One end of the pawl b334 and the inner ratchet 324 form a ratchet and pawl mechanism, and the other end engages with the teeth on the drive wheel 335.

[0031] by Figure 7 and Figure 8 For example, by cooperating with the internal ratchet 324 and the pawl b334, turning the take-up roller a32 counterclockwise can drive the take-up roller b33 to rotate together. In actual use, after the take-up roller a32 and take-up roller b33 are connected to the straps 1 on both sides, turning the take-up roller a32 counterclockwise can simultaneously wind up the straps 1 on both sides. When the strap 1 on one side of the take-up roller a32 is closer to the root of the thigh than the strap 1 on the other side, after the strap 1 on one side of the take-up roller a32 is tightened, the strap 1 on the other side will still be in a relatively loose state. At this time, the take-up roller b33 can continue to be turned counterclockwise to continue winding up the strap 1 on its side to tighten the entire device. After the usage requirements are met, the rotation is stopped.

[0032] During the rotation of the take-up roller b33, the inner ratchet 324 guides the pawl b334 to rotate around the connecting shaft between the pawl b334 and the connecting shaft 333. The slight deflection of the pawl b334 causes the transmission wheel 335 to rotate slightly synchronously through the engagement of its other end with the teeth on the transmission wheel 335. The rotation of the transmission wheel 335 causes the spring between it and the connecting shaft 333 to store energy, and after the pawl b334 disengages from one ratchet joint on the inner ratchet 324, it promptly resets to engage with the next ratchet joint.

[0033] Furthermore, the torsion spring 34 and the spring belonging to the transmission wheel 335 are arranged so that the take-up roller b33 and the take-up roller a32 are pressed together on both sides along the axial direction of the positioning roller 31, which facilitates a stable engagement with the pawl a313. At the same time, when it is necessary to loosen the strap 1, the corresponding side of the roller can be pushed. After loosening, the torsion spring 34 or the spring belonging to the transmission wheel 335 will promptly reset the roller to reconnect with the corresponding pawl, so as to facilitate the continued operation.

[0034] It is important to emphasize that, compared to simply using a bandage to wrap around the blood collection point for pressure hemostasis, the structural adhesive strip 12, the rigid plastic surface of the pressure pad 5, and the winding assembly 3 in this device distribute the pressure of the bandage on both sides of the blood collection point. This prevents the side with higher pressure from automatically winding towards the side with lower pressure during the winding process, which would cause pressure transfer to the blood collection point, resulting in poor hemostasis and subsequent problems.

[0035] The device is specifically designed for the patient's leg. The pressure for hemostasis at the blood collection point comes from the strap 1 that surrounds the patient's leg, rather than from the pressure of an external instrument. This avoids the pressure effect on the blood collection point being affected by the patient's movement. Slight movements of the patient will not affect the pressure hemostasis of the device, thus avoiding discomfort caused by the patient's inability to move for a long time.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
