Description

Technical Field

[0001] The invention relates to the field of medical instruments, and more particularly to a distal radial artery compressor with potassium ferrate hemostatic powder. Background Art

[0002] Transradial artery access (TRA) is the main puncture route in the field of interventional neurology, but TRA has several defects, the most common of which is radial artery spasm or even radial artery occlusion. Distal transradial artery access (dTRA, located at the snuff bottle position) puncture technique is a new interventional surgical puncture technique developed in recent years. It is an improvement on TRA puncture technique and has been proven to be safe and feasible, which can reduce vascular complications such as vascular occlusion rate. In addition, puncture from the distal end of the superficial palmar arch allows interventional physicians to maintain collateral vascular supply in the hand, preserve the patency of the proximal radial artery, and provide the integrity of TRA for future surgery.

[0003] The puncture point formed after interventional treatment through the distal radial artery generally requires compression for six to eight hours to stop bleeding. The commonly used method of hemostasis in clinical practice is to use a bandage to perform binding compression on the puncture site to stop bleeding. It covers a large area of ​​the skin, the hand is prone to swelling, it is not breathable, and the specific situation of the puncture site cannot be observed, and the compression strength cannot be controlled. At present, there is no compressor for clinical use after distal radial artery puncture. In addition, if the compression time is too long or too tight, it is easy to cause local hematoma, bleeding, and even forearm hematoma, edema, blisters, upper limb pain, numbness, nerve damage, radial artery occlusion and other vascular complications at the puncture site, thereby increasing the hospitalization time. After dTRA surgery, medical staff need to repeatedly release the patient's hand every 2-4 hours, and overnight observation is required, which significantly increases the nursing time and nursing costs.

[0047] like Figures 1 to 8 As shown, an embodiment of the present invention provides a distal radial artery compressor with potassium ferrate hemostatic powder, including a restraint belt 1, a first Velcro 3 is connected to one side of the front side of the restraint belt 1, a second Velcro 5 is connected to one side of the rear side of the restraint belt 1, an anti-falling component 2 is connected to the outer side of the restraint belt 1 for preventing the first Velcro 3 and the compression component 4 from accidentally separating, and a compression component 4 for compressing the distal radial artery is connected to the anti-falling component 2.

[0048] like Figure 5 and Figure 6 As shown, the compression component 4 includes a transparent frame 41 connected to the anti-falling component 2, and sliding grooves 45 are opened at the edges of both sides of the transparent frame 41, and the inside of the sliding grooves 45 is slidably connected with a shielding plate 43, and through holes 44 are opened on both sides of the inner surface of the transparent frame 41. The upper surface of the transparent frame 41 is rotatably connected with an internal threaded sleeve 46, and the internal thread of the internal threaded sleeve 46 is connected with an external threaded sleeve 47. The bottom of the external threaded sleeve 47 is connected to a powder release component 48, and the powder release component 48 is connected to a compression block 42.

[0049] The bottom of the external threaded sleeve 47 extends to the interior of the transparent frame 41, a rubber pad is provided on one side of the shielding plate 43, two telescopic rods are fixedly connected to the upper surface of the compression block 42, and the top of the telescopic rods is fixedly connected to the inner top of the transparent frame 41, and a silicone layer is fixedly connected to the edge of the lower surface of the transparent frame 41.

[0050] When compressing the patient's distal radial artery, the compression block 42 is placed at the distal radial artery puncture point so that the cavity 49 is buckled on the puncture point. By rotating the internal threaded sleeve 46, the external threaded sleeve 47 is driven to move downward through the action of the thread, driving the compression block 42 to approach and compress the patient's radial artery. The intensity of compression on the patient's hand can be effectively adjusted by rotating the internal threaded sleeve 46. At the same time, the transparent frame 41 is transparent so that the state of the hand around the puncture point can be clearly observed, which is not only convenient for compressing the distal radial artery, but also conducive to the doctor's timely observation of the patient's condition. Due to the long compression time, the shielding plates 43 on both sides of the transparent frame 41 can be slid to expose multiple through holes 44, so that the inside of the transparent frame 41 is connected to the outside, which can effectively ventilate the patient's hand. The transparent frame 41 covers a small area, and a silicone layer is provided on the bottom edge to maximize the comfort of the patient.

[0051] like Figure 6 As shown, the powder release assembly 48 includes a storage frame 481 fixed to the bottom of the externally threaded sleeve 47 and an internally threaded cap sleeve 484 threadedly connected to the top of the outer surface of the externally threaded sleeve 47, the inner bottom of the storage frame 481 is sleeved with a sealing ball 483, the top of the sealing ball 483 is fixedly connected with a pull rod 482, the top of the pull rod 482 passes through the interior of the externally threaded sleeve 47 and the internally threaded cap sleeve 484, the pull rod 482 and the internally threaded cap sleeve 484 slide with each other, the inner surface of the storage frame 481 is connected with a vibration assembly 485 for impacting and vibrating the storage frame 481, the compression block 42 is fixedly connected to the bottom of the storage frame 481, and the outlet of the storage frame 481 is connected to the interior of the cavity 49.

[0052] Compression of the patient's distal radial artery can stop bleeding to a certain extent. However, since the patient's physical condition is poor after the operation and it takes a long time for him to recover on his own, a storage frame 481 for storing hemostatic powder is installed at the bottom of the external threaded sleeve 47. After the compression block 42 compresses the distal radial artery, the pull rod 482 can be pulled upward to drive the sealing ball 483 away from the outlet at the bottom of the storage frame 481. The hemostatic powder inside the storage frame 481 all passes through the cavity 49 and falls on the patient's puncture point. The hemostatic powder includes thrombin, kaolin, chitosan, polyphosphate and potassium ferrate. Potassium ferrate stops bleeding faster than thrombin and kaolin. It is fast and will not cause allergies, infection, exothermic burns, etc. Potassium ferrate hemostatic powder can be used as an auxiliary drug for dTRA to promote coagulation and reduce rebleeding. Potassium ferrate is contained on a hydrophilic polymer. The polymer can quickly dehydrate and concentrate blood solids, while potassium ferrate and protein coagulate together to form a wound seal to stop bleeding. The components containing potassium ferrate will not reach the blood vessels, thereby reducing the coagulation time at the blood vessels and the observation time after distal radial artery access, improving patient satisfaction and comfort, shortening hospitalization time and hospitalization expenses, reducing costs, improving economic benefits, and increasing the number of surgeries, thereby accelerating healing while ensuring vascular integrity.

[0053] like Figure 7 and Figure 8 As shown, the vibration component 485 includes two mounting plates 4851 fixed on the inner surface of the storage frame 481 and two movable rods 4858 on the outer surface of the pull rod 482, a second through slot 4852 is opened inside the mounting plate 4851, a second spring 4853 is fixedly connected to one side of the inner surface of the second through slot 4852, a slide bar 4854 is fixedly connected to one side of the second spring 4853, an impact rod 4855 is fixedly connected to the outer surface of the slide bar 4854, a circular ring 4856 is slidably connected to the lower surface of the two mounting plates 4851, a triangle block 4857 is fixedly connected to the inner surface of the circular ring 4856, and a transmission rod 4859 is fixedly connected to the lower surface of the circular ring 4856.

[0054] The slide rod 4854 passes through the interior of the second through groove 4852 and slides and fits with each other. The bottom of the slide rod 4854 extends to the interior of the ring 4856. The pull rod 482 passes through the interior of the ring 4856. A rubber ball is provided on one side of the impact rod 4855.

[0055] However, when the hemostatic powder enters the cavity 49 from the storage frame 481, the hemostatic powder at the outlet may be blocked due to the narrow outlet at the bottom of the storage frame 481. At this time, the pull rod 482 is pulled upward to drive the movable rod 4858 to contact the bottom of the ring 4856, and then the pull rod 482 is turned to drive the two movable rods 4858 to rotate. The movable rod 4858 contacts the transmission rod 4859 and pushes the ring 4856 to rotate, and the ring 4856 drives multiple triangular blocks 4857 to rotate. The triangle block 4857 moves so that the hypotenuse of the triangle block 4857 contacts the slide bar 4854 and pushes the slide bar 4854 toward the pull rod 482 to be close to it, thereby compressing the second spring 4853. When the triangle block 4857 passes through the slide bar 4854, under the pulling force of the second spring 4853, the slide bar 4854 quickly moves toward the side wall of the storage frame 481 and hits it, thereby causing the storage frame 481 to vibrate through the impact, thereby promoting the hemostatic agent inside the storage frame 481 to quickly fall from the outlet to the puncture point, thereby preventing the hemostatic agent from being blocked.

[0056] like Figure 1 and Figure 2 As shown, the anti-falling component 2 includes a first connecting belt 21 and a second connecting belt 24 respectively fixed at the top and bottom of the restraining belt 1 and an adjustment component 25 fixed at one side of the restraining belt 1, a sub-buckle 22 is fixedly connected to one side of the first connecting belt 21, and a female buckle 23 is fixedly connected to one side of the second connecting belt 24.

[0057] The sub-buckle 22 and the female buckle 23 are located on different sides of the restraint belt 1, and the second Velcro 5 and the first Velcro 3 are adapted to each other.

[0058] like Figure 3 As shown, the adjustment component 25 includes a storage frame 251 fixed on one side of the restraining belt 1, the inner surface of the storage frame 251 is rotatably connected to a rotating shaft 252, the outer surface of the rotating shaft 252 is sleeved with a strap 253, a discharge port 254 is opened at the top of the storage frame 251, and a fixing component 255 is fixedly connected to one side of the inner surface of the storage frame 251.

[0059] When the compressor is worn on the patient's hand, the restraint belt 1 is wrapped around the patient's wrist, and the second Velcro 5 is tightly fitted on the first Velcro 3 for connection, and the loop formed by the two straps 253 is put on the base of the thumb, and the straps 253 are rolled up by rotating the rotating shaft 252, so that the transparent frame 41 can be adjusted to be buckled on the patient's hand position. After the adjustment is completed, the other rotating shaft 252 can be rotated to store the excess straps 253 to ensure that the two straps 253 are in a tight state, effectively ensuring that the transparent frame 41 is closely fitted to the patient's hand. At this time, the first connecting belt 21 and the second connecting belt 24 are buckled at the connection between the second Velcro 5 and the first Velcro 3, and the sub-buckle 22 and the female buckle 23 are buckled, so that the first connecting belt 21 and the second connecting belt 24 are tightly tied at the connection between the second Velcro 5 and the first Velcro 3, which can effectively prevent the second Velcro 5 and the first Velcro 3 from separating, and avoid accidental falling off of the compressor, causing discomfort to the patient.

[0060] like Figure 4 As shown, the fixing assembly 255 includes a ratchet gear 2555 fixed on the outer surface of the rotating shaft 252, a fixing plate 2553 fixed on one side of the inner surface of the storage frame 251, and a first through groove 2551 opened on one side of the storage frame 251, the lower surface of the fixing plate 2553 is fixedly connected with a first spring 2554, the bottom of the first spring 2554 is fixedly connected with a latch tooth 2552, and one side of the latch tooth 2552 is fixedly connected with a push rod 2556.

[0061] The teeth of the latching tooth 2552 mesh with the ratchet gear 2555 , and one side of the push rod 2556 passes through the interior of the first through slot 2551 .

[0062] After the strap 253 is rolled up, the shaft 252 lacks a limit, and the wearing time and place will cause the strap 253 to rotate inside the storage frame 251, making the tight strap 253 loose. At this time, through the cooperation of the ratchet gear 2555 and the latch tooth 2552, the shaft 252 drives the ratchet gear 2555 to rotate when the strap 253 is stored, so that the beveled edge of the teeth of the ratchet gear 2555 slides with the beveled edge of the teeth of the latch tooth 2552, ensuring that the shaft 252 can rotate smoothly. However, the latch tooth 2552 is always in contact with the ratchet gear 2555 under the pressure of the first spring 2554, which can prevent the ratchet gear 2555 from reversing and prevent the strap 253 from being pulled out of the storage frame 251, effectively improving the stability of the compressor.

[0063] The working process of the technical solution provided by the present invention is as follows:

[0064] First, wrap the strap 1 around the patient's wrist, put the two straps 253 on the base of the thumb, adjust the length of the strap 253 by rotating the shaft 252, and during the adjustment process, one strap 253 pulls the transparent frame 41 to adjust the position. After the adjustment is completed, roll up the excess strap 253 inside the storage frame 251, and fix the shaft 252 by the ratchet gear 2555 and the latch tooth 2552, and release the fixation of the shaft 252 by pushing the push rod 2556 to drive the latch tooth 2552 to move up.

[0065] Then, the compression block 42 is driven to compress the distal radial artery by rotating the internal threaded sleeve 46. The puncture point of the patient can be ventilated through the through hole 44, and the condition of the patient's hand can be observed through the transparent frame 41. The hemostatic agent inside the storage frame 481 can be sprinkled on the puncture point through the powder release component 48 to reduce the time for hemostasis and clotting. The storage frame 481 can be impacted and vibrated by the vibration component 485 when sprinkling the hemostatic agent to ensure that the hemostatic agent falls smoothly on the puncture point.

[0066] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
