Description

Technical Field

[0001] The invention relates to the technical field of gastrointestinal angiography, in particular to an auxiliary bracket dedicated to gastrointestinal angiography. Background Art

[0002] Gastrointestinal radiography can show its inner cavity and mucosal folds, morphology and function, etc. It has important diagnostic value for common gastrointestinal diseases such as ulcers and cancer. When performing gastrointestinal radiography, the patient needs to drink barium and then take various postures for gastrointestinal X-ray examination according to needs. The main equipment currently used is a gastrointestinal machine, which has a bracket to assist the patient in the examination. The bracket is a flippable bed, which is convenient for the patient to stand or lie down. Some of them are also equipped with adjustable backrests, so that the patient can perform radiography in a semi-recumbent position. For example, the announcement number is CN2183049 The Chinese utility model application of 45U discloses a special support for gastrointestinal ultrasound angiography, including a bed board; a support leg connected to the lower end of the bed board; a backrest adjustment assembly on the bed board; a leg straightening assembly and a foot support assembly on the bed board; the leg straightening assembly includes a motor connected to the bed board; a placement slot is provided on the bed board; a threaded rod is connected to the output end of the motor; a fixed block arranged in the placement slot and slidably connected to the bed board through a sliding assembly is threadedly connected on the threaded rod; a splint is fixedly connected to the fixed block; however, the current auxiliary support for patients used during gastrointestinal angiography has the following defects:

[0003] The existing auxiliary stents have poor functions. When patients undergo gastrointestinal radiography, after drinking barium, in order to ensure the radiography effect, they need to turn their bodies over so that the barium can stain the side wall of the gastrointestinal tract. Many examinees have difficulty turning themselves over, and need multiple caregivers to turn their bodies over, which is rather troublesome. During radiography, they usually need to lie in the supine position, the lateral position, etc. Many examinees with physical disabilities find it difficult to adjust their positions by themselves. Moreover, during radiography, due to position reasons, patients need to adjust their body position to cooperate with the radiography position, which is rather troublesome.

[0004] Therefore, we propose an auxiliary stent dedicated to gastrointestinal angiography to solve the above problems. Summary of the invention

[0048] Embodiment 3:

[0049] See also Figure 1-12, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is used, the radiography work should be carried out in a standing state first. The auxiliary mechanism 2 is in an upright state. The examiner's foot steps on the pedal 28. The patient needs to drink barium. If radiography of the digestive tract is required, radiography of the digestive tract can be carried out in a standing state. When performing gastrointestinal radiography, the examiner holds the roller handle 26 with his hand and his back is close to the support platform 21. Then the power frame mechanism 1 drives the auxiliary mechanism 2 to rotate to a horizontal state, and the posture adjustment component 24 is used to assist the patient to turn over, at least twice, so that the barium is contaminated with the patient's gastrointestinal side wall, and then radiography in supine position, lateral position and other postures is carried out. When performing lateral position, if the examiner is physically inconvenient, the posture adjustment component 24 can also be used to assist the patient to adjust the posture. If necessary, the patient's back can be supported by the adjustable support plate 211 to adjust to a semi-recumbent position for radiography; the function of the posture adjustment component 24 in the present invention is to assist the examiner The examiner turns over his body, and the examiner can also be assisted to adjust to the lateral position. When the patient needs to be assisted to turn over his body, the first U-shaped frame 242 and the second U-shaped frame 243 are raised, and the position of the high-friction flexible sheet 246 is raised, and then the two winding rollers 244 tighten the high-friction flexible sheet 246, so that the high-friction flexible sheet 246 will lift the examiner's body. At this time, the two winding rollers 244 rotate in the same direction, so that the high-friction flexible sheet 246 will move to one side, and under the action of friction, the examiner will turn to one side, and then rotate in the other direction to assist the patient to complete the turning work. Similarly, this method can also better adjust the patient to the lateral position, which is suitable for patients who are not convenient to move to perform angiography examinations; the dual-axis movable structure 14 in the present invention can move in both directions, so that when lying down, the horizontal position of the auxiliary mechanism 2 can be adjusted, so that the patient does not need to adjust his body position to cooperate with the angiography, which is more convenient.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial improvement of the present invention using this concept should be regarded as an infringement of the protection scope of the present invention.
