Background
Chest X-ray examination is the most widely used means of radiology in clinical use and is listed as one of the examination items of routine physical examination. The advantages of quick, simple and economical radiography are increasingly prominent, and become the priority of chest examination. The requirements of the chest X-ray examination and the position of the projection are as follows: 1. the patient must stand in front of the detection plate with the back towards the bulb tube in the correct standing position, the shoulder part sags, the back of the hand is forked at the waist, the scapula is pulled to internally rotate the upper arm, the prothorax is tightly attached to the detection plate, the head is slightly tilted backwards, and the lower jaw is arranged above the upper edge of the detection plate; 2. center line: the film is horizontally shot into the 6 th thoracic vertebra, and the air is closed for exposure after deep air suction. The difficulty of correct posture positioning is that the scapula is pulled open to rotate the upper arm inwards in chest X-ray examination. Since most technicians cannot clearly express the movement to the patient, and most patients are difficult to understand, the movement of the upper arm pronation cannot be in place in the chest photography, the scapula is not pulled away, partial lung images are blocked in the imaging, and missed diagnosis or misdiagnosis is easily caused. Especially, if the patient is weak or inconvenient to move, and cannot stand stably in front of the detection plate, it is more difficult to perform standard movements with the technician, resulting in failure of the mammography. Further, in hospitals, many patients who perform chest X-ray examinations do not wear lead clothes at all for the sake of greediness. If the patient wears the lead clothes according to the standard requirement, the examination time of the patient is prolonged and the radiation protection effect is influenced because some patients are inconvenient to wear the lead clothes.
In order to obtain effective and accurate lung images, clinical operation of chest X-ray radiographic examination requires an auxiliary device which can assist a patient in accurate positioning to be provided urgently, so that the operation difficulty of the current chest X-ray radiographic technology can be overcome, and the problem that the doctor and the patient cannot communicate clearly in the body position is solved.

Examples
Fabrication of the present example
The fence bracket provides structural support for the whole device and is made of square steel or round tubes made of stainless steel materials; the left and right supporting frames are fixedly connected through a front supporting beam, the left and right supporting frames are fixedly connected through a beam, and the rear fence door is connected to the left and right supporting frames through hinges.
The handle is made of stainless steel material and covered with sponge sleeves and is positioned at the left end and the right end of the structure, the handle can rotate forwards by 0-90 degrees through the ratchet handle positioning mechanism, and the handle stays at any position.
The limiting mechanism adopts a ratchet wheel type handle positioning mechanism or a top ball type multi-point limiting mechanism. When the ratchet handle positioning mechanism is rotated to a proper angle (the elbow joint is close to the detection plate) when the ratchet handle positioning mechanism is used, the handle is internally limited automatically in real time through the ratchet handle positioning mechanism during rotation. After the inspection is finished, the limit can be released through a reset pin, and the initial 0-degree state is recovered; another kind of spacing mode pushes up pearl formula multiple spot stop gear's structure is fairly simple, adopts the ball location of conventional application, and the structure is: set up a plurality of spring balls on the different angles of handle supporting seat, be equipped with the pit on the handle, the handle rotates to corresponding spring ball position, fixes a position in the spring ball embedding pit.
The fence support is fixedly connected with the lifting mechanism, and the fence support moves up and down through the lifting mechanism to adjust the height.
Because the device adjusts the height of the X-ray machine according to the height of the human body, the range of the lifting height is small, and the selection range of the lifting mechanism is wide. A lifting mechanism can be selected at will in the market. Such as: the lifting device comprises a chain and chain wheel transmission lifting mechanism, an electric push rod, a spiral lifting mechanism, a screw rod lifting mechanism or a hydraulic or pneumatic free type air spring or a self-locking type air spring or an electric rail type and the like, wherein the lifting device can be lifted manually and then automatically limited by adopting the air spring type lifting mechanism; this embodiment adopts chain sprocket drive elevating system. The servo motor and the guide rail of the chain and chain wheel transmission lifting mechanism are all commercial products selected from the market. If the guide rail adopts a conventional guide rail pair or a linear guide rail or a linear module or a ball screw and the like, the servo motor is fixed at the bottom of the fence bracket and can transmit through a chain and a chain wheel, or the servo motor can be fixedly connected at the upper part of the fence bracket and directly connected with the linear guide rail, and a technician regulates and controls the servo motor through a remote controller to adjust the vertical moving height of the fence bracket; the lifting mechanism is of conventional design and is marketed as a mature commodity and will not be described in detail here. No matter which kind of elevating system is adopted, as long as with rail support and elevating system rigid coupling, realize that rail support reciprocates through elevating system and adjusts the height, simultaneously, should guarantee the stability of going up and down, ensure patient's safety.
The lead screens are fixed on the frame, each lead screen is a square stainless steel lead screen with 0.5mmPb hung under the upper beam, and the screens are connected or hung with the left and the right supporting frames through hinges.
In order to move conveniently, the bottom of the device is provided with a roller.
The specific operation is as follows:
1. the device is arranged below a detection plate of an X-ray machine in advance, and the height of a bracket is adjusted to be lower for the requirements of patients with different heights;
2. opening the fence door to guide the patient into the fence support;
3. the patient faces the X-ray machine detection plate, stands in the position that leans on in this device center, at this moment the technician passes through remote controller fine setting rail support height and detection plate height, make patient's lower jaw lean on the detection plate upper lip, patient's both hands hold both sides handle respectively, instruct patient's both hands outside forward side horizontal direction rotating handle to suitable angle together, namely, both sides elbow joint rotates along with the handle, to the place ahead rotates, be close to the detection plate and even paste on the detection plate, shoulder blade moves outside to the lobe of the lung this moment, the device is fixed with patient's arm rising and auto-lock simultaneously, patient's chest is hugged closely the detection plate as far as possible at this moment, accomplish crucial pendulum position action. The technician adjusts the height of the X-ray tube ball, and then closes the rear lead screen device to complete X-ray exposure;
4. the rear part of the bracket is provided with a lead screen (0.5mmpb) for protection, thereby reducing the inconvenience of wearing lead clothes and shortening the examination time of patients.
The above detailed description of the device for assisting the correct positioning of a patient in X-ray chest radiography with reference to the embodiments is illustrative and not restrictive, several embodiments being possible within the limits of the invention, and therefore variations and modifications without departing from the general concept of the invention are to be considered within the scope of the invention.
