Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an auxiliary device for chest radiography of an X-ray machine. Background Art

[0002] The X-ray machine is one of the six major imaging devices in medicine and is a commonly used tool for diagnosing diseases. The principle is to use the various images formed by X-rays passing through the human body to diagnose patients, and it is widely used clinically. Among them, chest X-rays have become a routine examination.

[0003] At present, with the development of society, the problem of aging has gradually emerged, the number of elderly patients has increased year by year, and the number of elderly critically ill and disabled patients has increased year by year. The demand for bedside chest X-rays has increased, and bedside is a relatively suitable examination method, which is simple and fast. However, due to the limitations of the bedside chest X-ray conditions itself, there is no grid, and in addition, due to the unconsciousness of critically ill patients and their inability to cooperate, there are respiratory motion artifacts, making it difficult to guarantee the image quality. Often, with great effort, the bedside machine is pushed to the bedside of the ward, and the patient is moved to place the DR plate, but still a satisfactory image cannot be obtained, causing confusion in diagnosis and affecting clinical judgment and further treatment. In actual clinical work, infants, some children, and critically ill patients cannot cooperate well with breath-holding during general chest radiography and bedside radiography, resulting in blurred images, which often leads to poor effects of chest X-rays and abdominal plain films, affecting diagnosis. Some patients even need to be notified to recheck, which not only wastes time but also increases unnecessary radiation dose.

[0004] Therefore, how to solve the problem in the prior art that patients cannot cooperate effectively during chest radiography of an X-ray machine, resulting in the inability to obtain the best diagnostic effect, has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary device for chest radiography of an X-ray machine to solve the technical problem in the prior art that patients cannot cooperate effectively during chest radiography of an X-ray machine, resulting in the inability to obtain clear images and the best diagnostic effect. The many technical effects that can be produced by the preferred technical solutions provided by the present invention are described in detail below.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] The present invention provides an auxiliary device for chest radiography of an X-ray machine, including:

[0008] A triggering device, which is used for electrically connecting with the X-ray machine;

[0009] A respiratory gating device, which is electrically connected to the triggering device. The respiratory gating device includes a module assembly and a respiratory monitoring assembly, and the respiratory monitoring assembly is in communication with the module assembly.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Further, the triggering device includes a trigger module and a two - stage switch actuator.

[0012] Further, the module assembly includes a barometric pressure sensor, a respiratory signal generation module, and a peak synchronization signal output module.

[0013] Further, the respiratory monitoring assembly includes a strap, a self - expanding airbag, and a trachea. The self - expanding airbag is arranged along the length direction of the strap. One end of the trachea is fixedly connected to the strap and is in communication with the self - expanding airbag, and the other end of the trachea is in communication with the module assembly.

[0014] Further, the strap is provided with Velcro, and the trachea is made of soft silicone material.

[0015] The technical solution provided by this application has the following beneficial effects:

[0016] In the technical solution provided by the present invention, an auxiliary device for chest radiography of an X - ray machine includes a triggering device and a respiratory gating device. The triggering device is used to be electrically connected to the X - ray machine, the respiratory gating device is electrically connected to the triggering device. The respiratory gating device includes a module assembly and a respiratory monitoring assembly, and the respiratory monitoring assembly is in communication with the module assembly. With such a setting, first, the respiratory monitoring assembly is strapped to the patient's abdomen. When the patient breathes spontaneously, the gas volume in the respiratory monitoring assembly will change regularly. The gas volume in the respiratory monitoring assembly is transmitted to the module assembly to obtain a respiratory frequency curve graph of the patient. The peak of this graph is the end - inspiration moment. The module assembly converts the peak at the end - inspiration moment of the patient into an electrical signal and transmits it to the triggering device. The triggering device starts the function equivalent to the first gear of the X - ray machine exposure hand - brake 2 seconds before the triggering signal of the module assembly, and then starts the function equivalent to the second gear of the X - ray machine exposure hand - brake when receiving the triggering signal. Later, the two - stage signals are transmitted to the X - ray machine through the hand - brake socket in sequence to make the X - ray machine expose, realizing the exposure of the X - ray machine at the end - inspiration moment of the patient to obtain a clear image. By installing the auxiliary device for chest radiography of the X - ray machine on the X - ray equipment, clear chest images can be taken for patients who cannot cooperate and critically ill patients; thus solving the problem in the prior art that patients cannot cooperate effectively during chest radiography of the X - ray machine, resulting in unclear images and sub - optimal diagnostic effects.

[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] The purpose of this detailed implementation manner is to provide an auxiliary device for chest radiography of an X-ray machine; thereby solving the problem in the prior art that patients cannot cooperate effectively during chest radiography of an X-ray machine, resulting in unclear images and suboptimal diagnostic effects.

[0024] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims in any way. Further, all the contents of the configurations shown in the following embodiments are not necessarily essential to the solution of the invention described in the claims.

[0025] Please refer to Figure 1 - Figure 2 , this embodiment provides an auxiliary device for chest radiography of an X-ray machine, including a trigger device 1 and a breathing gating device. The trigger device 1 is used for electrically connecting to the exposure hand switch socket of the X-ray machine 2. The breathing gating device is electrically connected to the trigger device 1. The breathing gating device includes a module component 3 and a breathing monitoring component 4. The breathing monitoring component 4 is connected to the module component 3 through an air duct 7.

[0026] Set up in this way. First, place the patient in the best position, turn on the X-ray device, and adjust the machine to be suitable for shooting. Then, tie the breathing monitoring component 4 around the abdomen of the patient who cannot cooperate. Connect the air duct 7 in the breathing monitoring component 4 to the module component 3. Turn on the module component 3 to obtain the breathing frequency waveform diagram. Connect the module component 3 to the triggering device 1, and then replace the plug of the triggering device 1 with the plug of the hand switch 5 on the X-ray machine 2 and insert it into the hand switch jack of the X-ray machine 2. Turning on the triggering device 1 activates the first gear function equivalent to the exposure hand switch 5 of the X-ray machine 2. The staff leaves the room and remotely activates the connection between the module component 3 and the triggering device 1 from the next room. When the patient breathes spontaneously, the gas volume in the breathing monitoring component 4 changes regularly. The gas volume in the breathing monitoring component 4 is transmitted to the module component 3 to obtain the patient's breathing frequency curve graph. The peak of this graph is the end-inspiration moment. The module component 3 converts the peak at the end-inspiration moment of the patient into an electrical signal and transmits it to the triggering device 1. The triggering device 1 has already activated the first gear function equivalent to the exposure hand switch 5 of the X-ray machine 2 more than 2 seconds before receiving the trigger signal from the module component. After receiving the trigger signal, it activates the second gear function equivalent to the exposure hand switch 5 of the X-ray machine 2 and transmits the two gear signals to the X-ray machine 2 through the hand switch socket in sequence, realizing the exposure of the X-ray machine 2 at the end-inspiration moment of the patient to obtain a clear image. The auxiliary device for chest radiography of the X-ray machine is installed on the X-ray device to take clear chest images of patients who cannot cooperate and critically ill patients, thus solving the problem in the prior art that patients cannot cooperate effectively during chest radiography of the X-ray machine, resulting in unclear images and suboptimal diagnostic effects.

[0027] As an optional implementation manner, the triggering device 1 includes a trigger module and a two-gear switch actuator. The first gear switch of the switch actuator can be directly activated when the triggering device 1 is turned on, and the second gear is activated by the trigger module when receiving the trigger signal from the module component 3. The triggering device 1 can also be set to be activated according to the specific usage environment. Since the hardware system of the triggering device 1 in this embodiment, namely the trigger and the switch, are both prior art and the structure is relatively simple, the triggering device 1 will not be described in detail in this article.

[0028] As an optional implementation manner, in this embodiment, the module component 3 includes a pressure sensor, a breathing signal generation module, and a peak synchronization signal output module. Since the pressure sensor, the breathing signal generation module, and the peak synchronization signal output module are all prior art, the module component 3 will not be described in detail in this article.

[0029] As an alternative embodiment, the breathing monitoring component 4 includes a strap 6 and an air duct 7. Along the length direction of the strap 6, a self-expanding airbag 8 filled with sponge is provided. One end of the air duct 7 is fixedly connected to the strap 6 and is in communication with the self-expanding airbag 8, and the other end of the air duct 7 is in communication with the module component 3 through an air duct. The breathing monitoring component 4 can also be set according to the specific use environment, and is not limited to the form of the strap 6. For example, the strap 6 with the self-expanding airbag 8 can be replaced with a spiral telescopic air duct, and the same technical effects in this embodiment can be achieved. With such a setting, when the patient breathes spontaneously, the gas volume in the breathing monitoring component 4 will change regularly. The gas volume in the breathing monitoring component 4 is transmitted to the module component 3, and the module component 3 converts the airflow at the end of the patient's inspiration into an electrical signal to obtain the patient's respiratory frequency curve graph.

[0030] In a more specific embodiment, in this embodiment, a magic tape 9 is provided on the strap 6, and the material of the air duct 7 is preferably soft silicone material. With such a setting, the magic tape 9 can enable the strap 6 to meet the usage requirements of patients of different ages; in this embodiment, the air duct 7 is preferably made of soft silicone material, which can enable the air duct 7 to be bent arbitrarily, facilitating carrying and storage.

[0031] As an alternative embodiment, in this embodiment, the simulated hand brake 5 is preferably provided with two gears. With such a setting, according to the exposure process of the X-ray machine 2, first, the first gear of the hand brake 5 of the X-ray machine 2 is started synchronously. After a duration of more than 2 seconds, the second gear of the hand brake 5 is triggered by using the trigger signal converted at the peak moment of the module component 3 to expose the X-ray machine 2. It is realized that the exposure is carried out at the end of the patient's inspiration without cooperation to obtain a clear image.
