Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a vital sign monitoring device based on millimeter waves. Background Art

[0002] The millimeter wave vital sign monitor uses the wavelet transformation method to separate and reconstruct the respiratory signal, heartbeat signal and body movement signal according to the modulated pulse phase change signal to determine the health indicators of the human body. It can monitor the heart rate, respiratory rate, respiratory status, human body status, position range, movement information, human body distance, and human body orientation in real time to generate heart rate and respiratory rate waveforms.

[0003] In the prior art, a Chinese patent with publication number "CN215993958U" discloses a non-contact vital signs monitor, which adopts millimeter wave bio-radar technology. The bio-radar can obtain information such as the heart rate and respiratory rate of the human body by irradiating the human body. It is a non-contact measurement technology. The technology is integrated into the monitoring equipment, which is convenient to use. Furthermore, the entire detection equipment is integrated into the cover to simplify the structure. The body temperature detection, environmental temperature and humidity detection functions and reading light function are added, which is rich in functions and solves the problem that the current vital signs monitoring method is still contact-based, inconvenient to use, and has a relatively complex structure.

[0004] However, the above device still has the following problems during implementation:

[0005] During the detection process of the millimeter-wave bio-radar module, the radar needs to emit radio frequency waves with a frequency of 30 to 300 MHz. By pointing the millimeter-wave radar at the patient, the radar can obtain information such as the heart rate and breathing rate of people in a close range by emitting electromagnetic waves and processing echo signals. However, the installation position of the radar module is fixed, and the detection angle requirements of the millimeter-wave radar are usually relatively high. This is because the wavelength of the millimeter wave is shorter, which makes the beam width of its antenna narrower, which can easily lead to inaccurate feedback data.

[0006] For this reason, we provide a kind of mobile surgical medical operation table, in order to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a vital signs monitoring device based on millimeter waves. Through the cooperation of a supporting component, an adjusting component and a driving component, the present invention solves the problem that the installation position of the millimeter-wave biological radar module in the prior art is fixed, which makes it inconvenient to adjust the generation range, and the beam width of its antenna is narrow, which easily leads to inaccurate feedback data.

[0039] Specifically: the vital signs monitor 3 uses the millimeter wave radar 4 to emit microwaves with a wavelength of 10 mm to 1 mm and a frequency of 30 to 300 MHz of radio frequency wave radar technology. By pointing the millimeter wave radar 4 at the patient, the radar can obtain the heart rate, respiratory rate and other information of people in close range by emitting electromagnetic waves and processing echo signals, so that the patient's vital signs can be monitored non-contactly, avoiding the privacy problems caused by video monitoring.

[0045] See also Figure 1-7 On the basis of the specific embodiment 1, the front side of the rack 23 is meshed with the gear 24, the support shaft 9 is slidably connected to the inner wall of the guide plate 5, the other side of the threaded sleeve 13 is fixedly connected with a pressurized tube 25, a first infusion tube 26 is connected between the pressurized tube 25 and the fixed tube 20, a first solenoid valve 27 is sleeved on the surface of the first infusion tube 26, a second infusion tube 28 is connected between the pressurized tube 25 and the support shell 14, a second solenoid valve 29 is sleeved on the surface of the second infusion tube 28, a driving component includes a servo motor 30, the servo motor 30 is fixedly connected to the inside of the fixed shell 1, a rotating shaft 31 is fixedly connected to the output end of the servo motor 30, the bottom of the rotating shaft 31 is fixedly connected to the support plate 6, a clamping groove 32 is opened on the rear side of the fixed shell 1, a clamping plate 33 is fixedly connected to the front side of the mounting plate 2, a threaded seat 34 is fixedly connected to the front side of the mounting plate 2, and a fixing bolt 35 is penetrated through the front side of the fixed shell 1.

[0046] Specifically: the second sealing plug 21 is slidably connected inside the fixed tube 20. When high-pressure oil is injected into the fixed tube 20, the thrust of the oil can be transmitted to the telescopic rod 22 to drive the rack 23 to move. The gear 24 is meshed with the rack 23, and the up and down movement force of the telescopic rod 22 can be converted into a rotational force to drive the vital signs monitor 3 to rotate. The pressurized tube 25 is used to store high-pressure oil. The first infusion tube 26 is used to connect the pressurized tube 25 and the fixed tube 20. The first solenoid valve 27 is used to control the opening and closing of the first infusion tube 26. The second infusion tube 28 is used to connect the pressurized tube 25 and the supporting shell 14. The second solenoid valve 29 is used to control the opening and closing of the second infusion tube 28. The servo motor 30 can drive the rotating shaft 31 to rotate to adjust the horizontal angle of the vital signs monitor 3. The clamping plate 33 cooperates with the clamping groove 32 to facilitate the installation of the fixed shell 1.

[0047] The working principle of the present invention is as follows: when the use height of the millimeter wave radar 4 needs to be adjusted, the drive motor 7 can be started by an external controller, the drive motor 7 cooperates with the threaded rod 8 to drive the threaded sleeve 13 to move, the threaded sleeve 13 cooperates with the support shell 14 to drive the bracket 12 to move, the bracket 12 cooperates with the moving shaft 11 to drive the vital sign monitor 3 to move up and down, the use height of the millimeter wave radar 4 is adjusted, and the emission range of the millimeter wave radar 4 is increased;

[0048] After the vital signs monitor 3 is used, the drive motor 7 can be controlled to drive the vital signs monitor 3 to move downward for reset. The threaded sleeve 13 moves downward under the drive of the drive motor 7. The threaded sleeve 13 cooperates with the support shell 14 to drive the pulley 17 to contact the protrusion 19. The protrusion 19 pushes the pulley 17. After the pulley 17 is pushed, it squeezes the piston rod 16. The piston rod 16 cooperates with the first sealing plug 15 to compress the oil inside the support shell 14, and opens the second solenoid valve 29. The oil is injected into the pressurizing tube 25 through the second infusion tube 28, so that the oil pressure in the pressurizing tube 25 increases. After the infusion is completed, the second solenoid valve 29 is closed to store the oil pressure.

[0049] When the vital sign monitor 3 is adjusted to a specified height and the elevation angle of the millimeter wave radar 4 needs to be adjusted, the first solenoid valve 27 is started to open the first infusion tube 26, and the high-pressure oil in the pressurized tube 25 enters the fixed tube 20 and pushes the second sealing plug 21. The second sealing plug 21 cooperates with the telescopic rod 22 to drive the rack 23 to move, and the rack 23 cooperates with the gear 24 to drive the support shaft 9 to rotate. The support shaft 9 drives the vital sign monitor 3 to rotate, and the elevation angle of the millimeter wave radar 4 is adjusted to increase the transmission range of the millimeter wave radar 4.

[0050] When the horizontal angle of the millimeter-wave radar 4 needs to be adjusted, the servo motor 30 can be started. The servo motor 30 cooperates with the rotating shaft 31 to drive the support plate 6 to rotate, and the support plate 6 cooperates with the guide plate 5 to drive the vital sign monitor 3 to rotate, so as to adjust the horizontal angle of the millimeter-wave radar 4, reduce the impact of obstacles, and improve the accuracy of data reception.
