Description

Technical Field

[0001] The present invention relates to the technical field of signal monitoring, and in particular to a wireless signal monitoring and warning device used in a CT examination room. Background Art

[0002] CT (Computed Tomography) is a computer tomography scan that uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with extremely sensitive detectors to perform cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used to detect a variety of diseases. According to the different rays used, it can be divided into: X-ray CT (X-CT), ultrasonic CT (UCT) and gamma-ray CT (γ-CT), etc.

[0003] When a patient undergoes a CT scan, if the patient is not aware of taking out the mobile phone and carries it into the CT, carrying the mobile phone in the pocket during the examination will block the examination area, thereby affecting the efficiency of the examination. Therefore, to address this problem, a wireless signal monitoring and warning device for use in a CT examination room is proposed, which can detect whether the patient is carrying a mobile phone and prompt the doctor. Summary of the invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a wireless signal monitoring and warning device for a CT examination room.

[0005] The present invention proposes a wireless signal monitoring and warning device for a CT examination room, comprising a shell, on which an antenna module, a radio frequency receiving module, a signal processing module, a control and display module, and a power module are installed. The shell can be detachably installed on a hanging plate, on both sides of which a pair of ear seats are provided, and round holes are provided on the ear seats, and screws are inserted into the round holes. The hanging plate is also provided with an air blowing nozzle capable of blowing away dust on the shell. The shell and the air blowing nozzle are connected by an air blowing component. When a patient enters the CT room for examination, if the patient forgets to take off the mobile phone, the antenna module will sense the radio frequency signal of the mobile phone and transmit it. To the RF receiving module, the RF receiving module amplifies, filters and processes the signals received by the antenna module. The signal processing module will analyze these signals. According to the results of signal analysis and recognition, the control and display module will output corresponding information for alarm, thereby reminding the doctor that the patient is carrying a mobile phone. The hanging plate can be fixed by inserting the screws into the round hole and tightening them to the wall, and then the shell can be installed on the hanging plate to stably place the shell. During this period, the shell will blow air to the blowing nozzle through the blowing assembly, and the gas can be blown out from the blowing nozzle to blow away the dust on the shell, thereby achieving the effect of dust removal.

[0006] Preferably, L-shaped brackets are fixed on both sides of the hanging plate, a sliding column is fixed on the top of the bracket, and sliding sleeves are fixed on both sides of the shell. The sliding sleeves are provided with holes for the sliding column to pass through. The sliding column is aligned with the hole on the sliding sleeve, and then the sliding sleeve is put on the sliding column. The shell will be supported by the hanging plate and the shell can be installed.

[0007] Preferably, a vibrator is fixed on the back of the housing, and after the control and display module outputs information to the vibrator, the vibrator will vibrate, thereby achieving a warning effect.

[0008] Preferably, the blowing assembly includes a blowing structure, a first connecting pipe and a second connecting pipe. The blowing structure is mounted on the hanging plate and is located below the shell. The blowing structure is connected to the first connecting pipe. The second connecting pipe connects the first connecting pipe and the blowing nozzle. The second connecting pipe is a hose. A connecting seat is provided on the front side of the hanging plate. The blowing nozzle is rotatably connected to the connecting seat through a rotating shaft. When the vibrator vibrates, the shell vibrates along the direction of the sliding column, and the shell will intermittently squeeze the blowing structure. The blowing structure will blow air to the blowing nozzle through the first connecting pipe and the second connecting pipe. Since the second connecting pipe is a hose, when the second connecting pipe is inflated, the second connecting pipe will harden and then push the blowing nozzle upward, thereby increasing the blowing range of the blowing nozzle.

[0009] Preferably, the blowing structure includes an air cylinder, a piston, a pull rod and a spring. The air cylinder is fixedly connected to the hanging plate, the first connecting tube is connected to the bottom end of the air cylinder, the piston is located in the air cylinder, the pull rod is fixed to the top end of the piston, the top end of the pull rod is fixedly connected to the shell, the spring is sleeved on the sliding column, and the bottom end of the spring is fixedly connected to the bracket. When the shell moves downward, it will synchronously drive the pull rod and the piston to move downward, and the piston will press the gas in the air cylinder into the first connecting tube, thereby blowing, and then under the action of the spring, it will drive the shell, pull rod and piston to reset.

[0010] Preferably, the blowing structure includes an airbag, which is fixedly connected to the hanging plate. When the shell moves downward, the airbag will be squeezed and blow air into the first connecting tube, and then the elasticity of the airbag itself will drive the shell, the pull rod and the piston to reset.

[0011] Preferably, the antenna module is installed at the top end of the housing, and the antenna module is used to receive radio frequency signals.

[0012] Preferably, the RF receiving module is installed inside the shell, and the RF receiving module is used to amplify, filter and other processes the weak RF signal received by the antenna module. The signal is amplified to enable the subsequent circuit to effectively analyze the signal, and the filtering is to remove unnecessary interference signals and only retain the signal in the frequency range where the mobile phone signal is located.

[0013] Preferably, the signal processing module is installed inside the shell, and the signal processing module further analyzes and processes the signal processed by the radio frequency receiving module, digitizes the signal through digital signal processing DSP technology, and uses various algorithms to identify the characteristics of the signal. For example, it determines whether there is a mobile phone signal based on the specific frequency, modulation method, signal strength change and other characteristics of the mobile phone signal.

[0014] Preferably, the control module is responsible for the operation control of the entire detector, including parameter setting, starting and stopping detection, etc. through buttons on the shell. The display module is used to intuitively display the detection results to the user through the indicator light and speaker on the shell. When the indicator light lights up, the speaker will emit a prompt sound.
