A second loop fastener is fixedly positioned at the top center of the first adjusting plate, and the hook-and-loop fasteners are bonded to each other.
[0011] In one possible design, the hemostasis mechanism includes a tourniquet, a second frame, a movable plate, a first threaded rod, and a lower pressure plate. One end of the tourniquet is fixedly connected to the top side of the platform. A movable hole is provided at the center of the tourniquet to facilitate the movement of the movable plate. Two movable frames are movably fitted on the tourniquet. The two sides of the movable plate are fixedly connected to the sides of the two movable frames that are close to each other. One side of the second frame is fixedly connected to one side of the platform. A third hook and loop fastener is sewn onto one side of the tourniquet, and a third loop fastener is sewn onto one end of the tourniquet. The second frame is U-shaped, and one end of the tourniquet passes through the second frame. The hook and loop fasteners are bonded together. The first threaded rod is threadedly connected to the movable plate. The top of the lower pressure plate is rotatably connected to the bottom of the first threaded rod. A first knob is fixedly provided at the top of the first threaded rod to facilitate its rotation.
[0012] In one possible design, a palm-fixing strap for securing the palm is fixedly installed on one side of the top of the platform, a first frame is fixedly installed on one side of the platform, a fourth hook and loop fastener is sewn onto one side of the palm-fixing strap, and a fourth hook and loop fastener is sewn onto one end of the palm-fixing strap. The first frame is U-shaped, and one end of the palm-fixing strap passes through the first frame. The fourth hook and loop fastener are bonded together.
[0013] In one possible design, the platform is threaded with a second threaded rod and a third threaded rod for adjusting the height of the first and second adjusting plates. The top end of the second threaded rod is rotatably connected to the bottom of the first adjusting plate, and the top end of the third threaded rod is rotatably connected to the bottom of the second adjusting plate. Telescopic rods are fixedly installed on the bottom inner walls of both the first and second grooves. The telescopic parts of the two telescopic rods are fixedly connected to the bottom of the first and second adjusting plates, respectively. A third knob for easy rotation is fixedly installed at the bottom end of the second and third threaded rods.
[0014] In one possible design, two limiting rings are fixedly fitted on the first threaded cylinder, and a movable ring is movably fitted on the first threaded cylinder and located between the two limiting rings. A connecting plate is welded to one side of the movable ring, and a third frame is welded to one side of the connecting plate. The third frame is rectangular or arc-shaped, and a sharps box for placing sharps is provided on one side of the third frame. An L-plate is fixedly provided on one side of the sharps box, and one end of the L-plate is inserted into the third frame.
[0015] In one possible design, a fixing plate is welded to one side of the platform, a first fixing ring is welded to the top of the fixing plate, a first bearing is fixedly installed on the inner wall of the first fixing ring, a second threaded cylinder is fixedly installed on the inner ring of the first bearing, a second threaded post is threadedly connected to the inner wall of the second threaded cylinder, an adjusting post is fixedly installed at the top of the second threaded post, a concave plate is welded to the top of the adjusting post, the concave plate is concave, and a sterile operating tray is placed inside the concave plate.
[0016] In this application, during use, the entire unit is moved to the desired position via casters, which are lockable. The height of the platform is adjusted by rotating the first threaded post within the first threaded cylinder, according to the patient's height and comfort (during rotation, one hand can rotate the first threaded post while the other holds the platform to prevent rotation). The patient places their arm on the platform and on the arm pad (a glove is sewn into the arm pad in a one-piece structure, with the hand placed inside). Simultaneously, the palm is positioned on the hand strap, and the arm is wrapped by the arm pad (leaving the puncture site exposed). The exposed area is then secured by the adhesion of the first Velcro hook and loop sides. The outer arm is wrapped for warmth and comfort (the puncture site is exposed). The arm is secured to the first adjustment plate via the second hook and loop fasteners at the bottom of the arm pad. A hand-holding strap is passed through the first frame and fixed in place by the fourth hook and loop fasteners. The doctor then performs an arterial puncture at the appropriate location. After the puncture, a hemostatic mechanism is used. The tourniquet is pulled, and the moving plate is moved. The moving plate moves along the tourniquet via the moving frame. Once the tourniquet is above the puncture site, one end passes through the second frame and is secured by the third hook and loop fasteners. The first threaded rod is then rotated... The rotation of the first knob and the first threaded rod pushes the lower pressure plate downwards, effectively stopping bleeding. The lower pressure plate can be made of rubber or flexible plastic, depending on the specific needs. To adjust the height of the first and second adjustment plates, rotate the third knob at the bottom of the second and third threaded rods. The rotation of the second and third threaded rods moves the first and second adjustment plates, adjusting their height to suit different operational requirements. Sharp instruments used during puncture can be placed in a sharps container, which is hung on the third frame on one side of the table via an L-plate for easy removal and installation. A sterile operating tray placed inside the concave plate can be used to store medical instruments. The device involves holding the second threaded cylinder in one hand and the adjusting pin in the other, then rotating the second threaded cylinder. The bottom of the second threaded cylinder rotates through the first bearing inside the first fixing ring, adjusting the position of the second threaded pin inside the second threaded cylinder and adjusting the height of the concave plate to facilitate aseptic operation by the doctor. Because it can rotate through the first bearing, the aseptic operating tray can be rotated horizontally, facilitating the doctor's operation. The sharps box can rotate freely on the first threaded cylinder through the movable ring. The entire device can be moved anywhere using casters to place the arm for puncture without relying on the bedside, making it more convenient and comfortable. The arm pad can be made of pure cotton with a certain thickness, and the specific material can be selected according to actual needs. The platform can be made of stainless steel.
[0017] In this utility model, the integrated arterial puncture operating table, through a warming mechanism, allows the patient to place their arm on the table body and on the arm pad, while simultaneously positioning their palm on the palm fixing strap. The arm is wrapped by the arm pad, and the exposed arm is wrapped and warmed by the adhesion of the first hook and loop fastener surfaces, thus improving comfort. Since the bottom of the arm pad is fixed to the first adjustment plate by the second hook and loop fastener surfaces, the arm is thus fixed to the first adjustment plate.
[0018] In this utility model, the integrated arterial puncture operating table uses a hemostasis mechanism to pull the tourniquet and move the moving plate. The moving plate moves on the tourniquet via a moving frame. After moving above the puncture position, one end of the tourniquet passes through the second frame and is fixed by the hook and loop sides of the third Velcro. Then, the first knob on the first threaded rod is rotated, and the rotation of the first threaded rod pushes the pressure plate down, thereby effectively stopping the bleeding.
[0019] In this invention, the warming mechanism can wrap the exposed arm to keep it warm and improve comfort, while the hemostasis mechanism can effectively stop bleeding. Since the whole unit can be moved anywhere by the casters to place the arm for puncture, it does not need to be near the bed, making it more convenient and comfortable. Attached Figure Description
