Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an upper limb fixing device for contrast injection. Background Art

[0002] Angiography is a commonly used medical examination method that introduces a substance with a higher or lower density than the human body into the part to be examined in the human body, artificially creating a density difference in the part to be examined to form a contrast and achieve the purpose of diagnosis.

[0003] During the operation, the patient needs to lie still on the operating table, and the skin on the vein to be imaged is disinfected and locally anesthetized. A high-pressure syringe is connected to an indwelling needle in the upper limb to inject contrast agent into the body. During the examination, the patient needs to cross his hands above his head, lie flat on the operating table, and maintain the posture until the vein into which the contrast agent is injected can be shown on the X-ray, and a series of X-ray photos are taken.

[0004] In order to prevent patients from maintaining the same posture for a long time, causing arm pain, and moving the arm to affect the imaging effect, an upper limb fixation frame that is convenient for fixing the upper limbs has been invented, which generally includes a support rod and a support plate. However, it still has the following shortcomings:

[0005] 1. The existing arm support frame has an upper arm support plate and a lower arm support plate rotatably connected by a rotating shaft. The lower arm support plate usually rotates up and down around the upper arm support plate to adjust the angle between the upper arm and the lower arm. During angiography, the patient needs to keep his hands crossed and raised above the head. The existing arm support frame cannot meet the patient's need to adjust the arm support frame in this posture.

[0006] 2. When the patient crosses his hands and raises them above his head, under the restriction of the human body's shoulder and neck muscles, shoulder and neck back muscles and upper arm posterior muscles, when the arms are placed on the flat support board, the upper arm to the forearm is in a downward trend, and the upper arm is higher than the forearm and wrist, which is more likely to cause numbness at the front end of the forearm. The existing support frame cannot meet the requirement of lifting the forearm while adjusting the angle between the upper arm support board and the forearm support board, and cannot effectively improve the patient's comfort.

[0007] Therefore, how to design an upper limb fixation device for contrast injection that can solve the above technical problems is a technical problem that needs to be solved. Utility Model Content

[0008] In order to solve the above problems, the purpose of the utility model is to provide an upper limb fixation device for contrast injection, which solves the problem that the existing arm support frame is difficult to flexibly adjust the use angle and has low comfort level.

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a U-shaped base and an upper limb support assembly rotatably arranged at the bottom of the base; the upper limb support assembly includes an upper arm support plate rotatably connected to the U-shaped base, an upper arm extension plate slidably connected to the upper arm support plate, and a forearm support plate hinged to the upper arm extension plate; an installation groove is provided on the upper end surface of the upper arm support plate, and the upper arm extension plate is slidably connected to the upper arm support plate through the installation groove; the upper end surface hinge of the forearm support plate has a rotating support plate for flipping upward; an inflatable airbag is provided between the rotating support plate and the forearm support plate; a strap for fixing the patient's upper arm is provided on the outer walls on both sides of the upper arm support plate; a strap is fixedly provided on both sides of the upper end surface of the upper arm extension plate; a strap is fixedly provided on both sides of the upper end surface of the forearm support plate for fixing the patient's forearm.

[0010] Furthermore, a fastening bolt is penetrated through the lower end surface of the U-shaped base, and the fastening bolt is threadedly connected to the U-shaped base.

[0011] Furthermore, the end of the upper arm extension plate away from the upper arm support plate is rotationally connected to the lower arm support plate via a vertical rotating shaft.

[0012] Furthermore, the upper end surfaces of the upper arm support plate, the upper arm extension plate, and the lower arm support plate are flush with each other.

[0013] Furthermore, the side walls on both sides of the installation groove are provided with sliding grooves along the length direction of the installation groove, and the side walls on both sides of the upper arm extension plate are provided with sliding blocks at positions corresponding to the sliding grooves, and the sliding blocks are clamped in the sliding grooves.

[0014] Furthermore, the strap one, strap two, and strap three are all Velcro straps that fit together.

[0015] Furthermore, the inflatable airbag is provided with an inflation and deflation interface.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model is provided with an upper arm support plate and a forearm support plate rotatably connected to the upper arm support plate through a vertical rotating shaft. By moving the forearm support plate to the left or right, the relative angle between the upper arm support plate and the forearm support plate can be flexibly adjusted, so that the patient can preset the use position of the forearm support plate according to his own needs, thereby improving the comfort of use.

[0018] 2. The utility model has a rotating support plate rotatably arranged on the upper end surface of the forearm support plate, and an inflatable airbag is arranged between the rotating support plate and the forearm support plate. The rotating support plate is lifted by inflating the inflatable airbag to lift the patient's forearm, thereby improving the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS
