Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a distal radius splint. Background Art

[0002] The radius is located on the lateral part of the forearm and is divided into one body with two ends. The upper end is enlarged and called the radial head. The articular fovea on the upper surface of the head articulates with the capitulum of the humerus; the surrounding annular articular surface articulates with the ulna; the part below the head is slightly thinner and called the radial neck. There is a prominent radial tuberosity on the inner lower side of the neck. The body of the radius is prism-shaped, and the inner edge is a thin and sharp interosseous margin. The lower end is concave in front and convex behind, and protrudes downward on the outside, called the styloid process. There is an articular surface on the inner surface of the lower end, called the ulnar notch, which articulates with the head of the ulna, and there is a wrist joint surface below to articulate with the carpal bones.

[0003] When a person falls and lands with the hand in hyperextension, indirect violence can cause a distal radius fracture. After a radius fracture, a splint is needed to assist in recovery. The splint can be tied with a strap. During use, it is not convenient to determine the tying strength of the strap, which can only be judged by the doctor's experience and cannot be visually shown.

[0004] Therefore, the technical personnel in this field provide a distal radius splint to solve the problems raised. Content of the Utility Model

Three side blocks are arranged on one side of the first wide plate. Two vertical rods are symmetrically and fixedly installed inside the side blocks. A sliding plate is sleeved on the two vertical rods together. A pulling frame is fixedly installed at the bottom of the sliding plate. The pulling frame penetrates through the bottom of the side block. A spring is sleeved on the vertical rod, and the spring is located between the lower surface of the sliding plate and the inner bottom wall of the side block. A cross plate is fixedly installed horizontally on the pulling frame. A moving column is fixedly inserted on the cross plate. An outer groove is opened on one side of the side block. A through groove is opened through between the outer groove and the inside of the side block. The moving column is slidably arranged in the through groove. An indicating bar is fixedly installed at one end of the moving column. A scale bar is also arranged in the outer groove. A first sleeve is also sleeved at the bottom of the pulling frame; Three groups of second fixing frames are arranged on one side of the second wide plate, and each group of second fixing frames has two. A second sleeve is sleeved on the second fixing frame; And the three groups of second fixing frames respectively correspond to the three side blocks; Three limiting grooves are opened on each of the narrow plates. A first connecting band and a second connecting band are respectively arranged in two corresponding limiting grooves. One ends of the two second connecting bands respectively bypass the corresponding two second sleeves and are bonded through a magic tape. The other ends of the first connecting band and the second connecting band respectively bypass the first fixing frame and the first sleeve and are bonded through a magic tape.

[0008] Preferably, two guiding frames are symmetrically and fixedly installed on one side of the first wide plate. Two side plates are symmetrically and fixedly installed on both sides of the side block. The two side plates are respectively slidably inserted into the two guiding frames. The guiding frames can limit the side plates, with good stability and can prevent movement.

[0009] Preferably, three arc-shaped openings are provided at the top and bottom of the first wide plate and the second wide plate, and the first connecting belt and the second connecting belt pass through the corresponding arc-shaped openings and are in contact, which can perform limiting and can also protect the first connecting belt and the second connecting belt.

[0010] Air bags are arranged on the inner sides of the first wide plate, the second wide plate and the two narrow plates. The air bags are divided into multiple regions, and each region corresponds to an air inlet and an air outlet.

[0011] In summary, the utility model includes the following beneficial technical effects:

[0012] The second sleeve and the first fixing frame can be connected through the first connecting belt. After the second connecting belt is sleeved on another second sleeve in the same group, the other end of the second connecting belt can be pulled around the first sleeve as needed and then bonded through the magic tape. The pulling frame moves downward under force, the sliding plate compresses the spring, and the indicating bar at one end of the moving column can point to the scale on the scale bar, so that different clamping forces can be observed and adjusted, which is more intuitive and can protect the patient. The air bags in each region can be inflated according to the injured position, which can improve the installation effect of the first wide plate, the second wide plate and the two narrow plates and can also prevent sliding.
