Technical Field

[0002] Puncture intervention of radial artery for coronary heart disease is safe and feasible in clinical practice. Radial artery compression hemostat is a hemostatic device used after vascular intervention surgery. Compression hemostat uses mechanical compression force to promote wound coagulation and initial closure, which requires a certain compression time. However, radial artery compression hemostat has irreplaceable clinical use value due to its advantages such as easy operation, high safety, no foreign body implantation, easy recovery after surgery, and reusability of puncture site. The existing radial artery compression hemostat is applied to the wrist puncture site and is composed of an elastic bandage, a compression plate and a compression knob. The structure is simple. During use, if the patient moves the wrist joint or twists the forearm, it is very easy to cause the compression point of the hemostat to shift, which is not conducive to hemostasis and recovery of the puncture site. In addition, each time the compression hemostasis operation is performed on the patient, the skin around the compression point needs to be disinfected and hemostatically treated to prevent external bacteria from entering the puncture site and causing a series of complications.

At the same time, the threaded rod 22 rotates to drive the first sprocket 31 to rotate, the first sprocket 31 rotates to drive the second sprocket 33 to rotate, the second sprocket 33 rotates to drive the first shaft 34 to rotate, the first shaft 34 rotates to drive the first gear 37 to rotate, the first gear 37 rotates to drive the second gear 38 to rotate, the second gear 38 rotates to drive the fourth shaft 312 to rotate and move back and forth left and right, the fourth shaft 312 rotates and moves back and forth left and right to drive the second moving rod 313 to move back and forth left and right, the second moving rod 313 moves back and forth left and right to drive the piston plate 315 to move back and forth left and right; When the piston plate 315 moves to the left, the first one-way valve in the medicine inlet hose 316 opens, the second one-way valve in the delivery hose 35 closes, and the disinfectant hemostatic liquid is sucked into the medicine cartridge 314 through the external medicine storage box; When the piston plate 315 moves to the right, the first one-way valve in the medicine inlet hose 316 is closed, and the second one-way valve in the delivery hose 35 is opened, and the disinfectant hemostatic liquid sucked into the medicine cartridge 314 is delivered to the arc-shaped medicine spraying plate 3 through the delivery hose 35, the liquid separation plate 28 and the connecting pipe 311 for spraying; In this way, the arc-shaped spray plate 3 sprays the disinfectant hemostatic liquid to the puncture pressure point and the surrounding skin, without the need for manual disinfection by medical staff, thus preventing external bacteria from entering the puncture site and causing a series of complications. The operation is relatively convenient, thus improving the practicality of the device. At the same time, the liquid separation plate 28 moves downward, driving the first connecting rod 29 to move downward, and the first connecting rod 29 moves downward, driving the rubber layer 210 to move downward, and the rubber layer 210 moves downward to compress the puncture site of the patient's wrist to stop bleeding, thereby using mechanical pressure to promote blood coagulation and preliminary closure of the wound; At the same time, the liquid separation plate 28 moves downward to drive the third moving rod 41 to move downward, the third moving rod 41 moves downward to drive the second rack to move downward, the second rack moves downward to drive the third gear 42 to rotate, the third gear 42 rotates to drive the fifth shaft 43 to rotate, the fifth shaft 43 rotates to drive the third sprocket 44 to rotate, the third sprocket 44 rotates to drive the fourth sprocket 46 to rotate, the fourth sprocket 46 rotates to drive the sixth shaft 47 to rotate, the sixth shaft 47 rotates to drive the fourth gear 48 to rotate, the fourth gear 48 rotates to drive the first rack to move upward, the first rack moves upward to drive the fourth moving rod 49 to move upward, the fourth moving rod 49 The upward movement drives the sliding column 411 to move upward, the sliding column 411 moves upward to squeeze the upper side of the second slide groove to drive the lever 412 to move toward each other, the lever 412 moves toward each other to drive the moving plate 413 to move toward each other, the moving plate 413 moves toward each other to drive the fifth moving rod 414 to move toward each other, the fifth moving rod 414 moves toward each other to drive the flexible air cushion 415 to move toward each other, the flexible air cushion 415 moves toward each other to clamp and fix the arms on both sides of the puncture site of the patient's wrist to prevent the patient from moving the wrist joint and twisting the forearm during compression and hemostasis, which is very likely to cause the hemostat compression point to shift, which is not conducive to hemostasis and recovery of the puncture site; When the compression hemostasis is completed, the driving member 21 is driven in the reverse direction, and the flexible air cushion 415 moves away to release the clamping fixation. At the same time, the rubber layer 210 moves upward to release the compression hemostasis on the puncture site of the patient's wrist. At the same time, the arc-shaped spray plate 3 sprays the disinfectant hemostatic liquid onto the puncture pressure point and the surrounding skin again, and the medical staff does not need to manually disinfect again for further sterilization.
[0020] The present invention provides a compression mechanism, so that the rubber layer moves downward to compress the puncture site on the patient's wrist to stop bleeding, and then uses mechanical compression force to promote blood coagulation and preliminary closure of the wound. At the same time, the arc-shaped medicine spraying plate is always facing the puncture pressure point and the surrounding skin during the downward movement. The spraying mechanism is provided, so that the rubber layer moves downward to compress the puncture site on the patient's wrist to stop bleeding, and the arc-shaped medicine spraying plate is always facing the puncture pressure point and the surrounding skin during the downward movement. The arc-shaped medicine spraying plate sprays disinfectant hemostatic liquid to the puncture pressure point and the surrounding skin, and there is no need for medical staff to perform manual disinfection, so as to prevent external bacteria from entering the puncture site to cause a series of complications, and the operation is simple and convenient. The invention is more convenient and improves the practicability of the device. By setting a fixing mechanism, the rubber layer moves downward to compress the puncture site of the patient's wrist to stop bleeding. During the downward movement of the arc-shaped spray plate, the puncture pressure point and the surrounding skin are always directed to the arc-shaped spray plate. The disinfecting hemostatic liquid is sprayed to the puncture pressure point and the surrounding skin through the arc-shaped spray plate. At the same time, the flexible air cushion moves toward each other to clamp and fix the arms on both sides of the puncture site of the patient's wrist, so as to prevent the patient from moving the wrist joint and twisting the forearm during the compression hemostasis, which is very likely to cause the hemostat pressure point to shift, which is not conducive to hemostasis and the recovery of the puncture site. The invention has a simple and reliable structure, a good compression hemostat effect, is easy to control, and is suitable for promotion.
