[0002] The vital signs monitor consists of a host (containing the VSM300 monitor embedded software component), a blood pressure cuff and hose, a pulse oximeter (SpO2) sensor and extension cable, a temperature probe, an oral probe and a probe cover. This product has the functions of non-invasive blood pressure (NIBP), pulse rate, mean arterial pressure (MAP), blood oxygen saturation (SpO2), and body temperature monitoring. It can be used by physicians and medically qualified personnel to monitor the non-invasive blood pressure, pulse rate, body temperature, non-invasive arterial oxygen saturation (SpO2) and body temperature in normal mode and axillary mode for neonates, children and adult patients. This product can be used in medical / surgical wards, hospitals, or other monitoring environments. This product is for use by doctors or qualified medical personnel only.

[0003] At present, in order to ensure the health monitoring of the elderly, postoperative observation personnel and people with underlying diseases, it is necessary to use vital signs monitors at home to monitor the vital signs of the monitored person during sleep. Since the wired vital signs monitors in the prior art have limitations in use, a wireless vital signs monitor suitable for ordinary people has emerged. The monitor uses the principle of millimeter-wave bioradar to realize the vital signs monitoring of the monitored person, and can promptly inform the family members of the monitored person when abnormalities are found, thereby achieving the purpose of health monitoring.

[0004] However, when using the existing wireless vital signs monitor, it is found that it needs to be used with a mounting ring and screws. Specifically, the mounting ring is first installed at the bottom of the monitor, and then the mounting ring is installed on the fixed object through screws. The above installation method has the disadvantages of damaging the fixed object, cumbersome operation, and inconvenient disassembly and installation. For this reason, we propose a portable wireless vital signs monitor. Summary of the invention

[0013] By adopting the above technical solution, an atomization effect is achieved, thereby increasing the functionality of the monitor.

[0014] The present invention is further configured such that a dust removal component is installed on one side of the atomization bin on the outer side of the shell to remove dust from the end face of the millimeter-wave biological radar.

[0017] By adopting the above technical solution, the driving effect of the dust removal component is achieved and the synchronous driving of the atomization component is completed at the same time.

[0018] In summary, the present invention mainly has the following beneficial effects:

[0019] 1. The present invention sets an installation component and an adjustment component. First, when installing the monitor, the monitor is moved to the position to be installed, and then the suction cup is pressed against the end face of the fixed object. At this time, the shell can be pulled outward to make the millimeter-wave biological radar in an unfolded and adjustable working state. While pulling the shell outward, the bottom plate will move upward, so the vertical rod will move upward in the card holder, so that the vertical rod moves from the first engaging position in the card holder to the second engaging position, completing the unfolding of the millimeter-wave biological radar. Furthermore, the movement of the above-mentioned bottom plate will drive the synchronization rod to move, and the synchronization rod will then drive the first piston plate to move in the first cylinder through the first driving rod. At this time, the negative pressure generated in the first cylinder causes the gas in the suction cup air cavity to flow into the first cylinder through the air pipe, so the suction cup will Under the action of the external atmospheric pressure, it is tightly adsorbed on the surface of the fixed object, thereby realizing the convenient installation of the monitor. Similarly, when disassembling the monitor, since the monitor is not needed at this time, the shell can be pushed inward, so that the millimeter-wave biological radar moves inward with the shell and is in a closed non-working state. At this time, the bottom plate will push the vertical rod to move downward, and then the vertical rod moves from the second engaging position of the card seat to the first engaging position, completing the storage of the millimeter-wave biological radar. When the above-mentioned bottom plate moves downward, the bottom plate will drive the first driving rod to move downward through the synchronization rod, and the first driving rod will then push the first piston plate to move downward, and the gas in the first cylinder will be discharged into the air cavity of the suction cup through the air pipe. At this time, the air pressure inside and outside the suction cup is the same, so the monitor can be disassembled;

[0020] 2. The present invention is provided with an atomizing component, a dust removal component and a driving component. Since the present monitor is for monitoring the vital signs of the monitored person during sleep, the atomizing component can be used to assist sleep. Specifically, a liquid that helps sleep (such as floral water to reduce mosquitoes) is injected into the liquid storage tank through the water replenishment port of the liquid storage tank to achieve the effect of assisting sleep, and the dust removal component is synchronized with the atomizing component to remove dust from the surface of the millimeter-wave bioradar. Specifically, the electric guide rail drives the first slider to move on the electric guide rail, and the movement of the first slider synchronously drives the second piston plate to move, so a negative pressure is formed inside the second cylinder to inhale gas from the outside. At the same time, the first slider The second driving rod will drive the second slider to move, and the second slider will drive the third piston plate to move, squeezing the remaining small amount of liquid in the liquid storage tank into the liquid storage tank. Then the electric guide rail will drive the first slider to move in the opposite direction. At this time, the first slider will squeeze the gas in the second cylinder through the second piston plate and enter the jet port through the intake pipe to be ejected. The airflow ejected from the jet port can remove the dust on the surface of the millimeter-wave bioradar, ensuring the monitoring accuracy of the millimeter-wave bioradar. The reverse movement of the first slider will also drive the second slider to move in the opposite direction through the second driving rod, and the second slider will therefore drive the third piston plate to move in the opposite direction, using the negative pressure principle to achieve the effect of replenishing liquid from the liquid storage tank.

[0039] Embodiment 2

[0040] like Figure 7-Figure 9As shown, it is basically the same as the first embodiment, except that: it is additionally provided with an atomizing component 4, a dust removal component 5 and a driving component 6, thereby realizing the extension of the functionality of the monitoring instrument and driving the atomizing component 4 and the dust removal component 5 to be linked by the driving component 6, realizing dust removal on the surface of the millimeter wave bio-radar 103 while atomizing, thereby achieving the effect of improving the detection accuracy of the monitoring instrument;

[0041] Specifically, an atomizing assembly 4 is arranged on the outside of the housing 102 to extend the functions of the monitor. The atomizing assembly 4 includes a liquid storage tank 401 fixed on the outer wall of the housing 102 and having a water supply port, and an atomizing bin 402 is installed above the liquid storage tank 401, and a water inlet pipe 403 is connected between the atomizing bin 402 and the liquid storage tank 401, and a plurality of groups of annularly distributed atomizing nozzles 404 are installed on the outer wall of the atomizing bin 402;

[0042] A dust removal component 5 is also installed on the outer side of the shell 102, located on one side of the atomization bin 402, to remove dust from the end face of the millimeter-wave bio-radar 103. The dust removal component 5 includes a second cylinder 501, and an air jet 502 is provided on the top inner wall of the shell 102. An air inlet pipe 503 for supplying air to the air jet 502 is connected between the second cylinder 501 and the inner wall of the shell 102;

[0043] The outer side of the shell 102 is located between the atomizing assembly 4 and the dust removing assembly 5, and a driving assembly 6 is installed to realize driving the atomizing assembly 4 and the dust removing assembly 5. The driving assembly 6 includes an electric guide rail 601 arranged on the outer side of the shell 102 and passing through the second cylinder 501, and the end of the electric guide rail 601 is connected to the guide rail 602 passing through the atomizing bin 402, the outer wall of the electric guide rail 601 is sleeved with a first slider 603 adapted to the electric guide rail 601, and the end of the first slider 603 is fixedly connected to a second piston plate 604 slidably connected to the inner wall of the second cylinder 501, the outer wall of the guide rail 602 is sleeved with a second slider 605 adapted to the guide rail 602, and the end of the second slider 605 is fixedly connected to a second piston plate 606 slidably connected to the inner wall of the atomizing bin 402, and the other end of the second slider 605 is fixedly connected to a second driving rod 607 fixedly connected to the outer wall of the first slider 603;

[0044] In addition, the electric guide rail 601, the guide rail 602, the second drive rod 607 and the first drive rod 205 are all connected to corresponding parts by means of shaft sealing to ensure sealing.

[0045] The working principle of the present invention is as follows: first, when installing the monitor, the monitor is moved to the position to be installed, and then the suction cup 201 is pressed against the end surface of the fixed object, and then the shell 102 can be pulled outward to make the millimeter wave bio-radar 103 in an unfolded and adjustable working state, and while the shell 102 is pulled outward, the bottom plate 301 will move upward, so the vertical rod 303 will move upward in the holder 302, so that the vertical rod 303 moves from the first engaging position in the holder 302 to the second engaging position, and the millimeter wave bio-radar 103 is unfolded;

[0046] Furthermore, the movement of the bottom plate 301 drives the synchronization rod 207 to move, and the synchronization rod 207 drives the first piston plate 206 to move in the first cylinder 204 through the first driving rod 205. At this time, the negative pressure generated in the first cylinder 204 causes the gas in the air cavity 202 of the suction cup 201 to flow into the first cylinder 204 through the air pipe 203. Therefore, the suction cup 201 is tightly adsorbed on the surface of the fixed object under the action of the external atmospheric pressure, thereby realizing the convenient installation of the monitor;

[0047] Similarly, when disassembling the monitor, since the monitor is not needed at this time, the shell 102 can be pushed inward, so that the millimeter-wave bioradar 103 moves inward with the shell 102 and is in a closed non-working state. At this time, the bottom plate 301 will push the vertical rod 303 to move downward, thereby moving the vertical rod 303 from the second engaging position of the holder 302 to the first engaging position, completing the storage of the millimeter-wave bioradar 103. When the bottom plate 301 moves downward, the bottom plate 301 will drive the first driving rod 205 to move downward through the synchronization rod 207. The first driving rod 205 then pushes the first piston plate 206 to move downward, and the gas in the first cylinder 204 is discharged into the air cavity 202 of the suction cup 201 through the air pipe. At this time, the air pressure inside and outside the suction cup 201 is the same, so the monitor can be disassembled;

[0048] In addition, since the monitor is for monitoring the vital signs of the monitored person during sleep, the atomizing component 4 can be used to assist sleep, that is, a liquid that helps sleep (such as floral water to reduce mosquitoes) is injected into the liquid storage tank 401 through the water replenishment port of the liquid storage tank 401 to achieve the effect of assisting sleep, and the dust removal component 5 is synchronized with the atomizing component 4 to remove dust on the surface of the millimeter wave bioradar 103;

[0049] Specifically, the electric guide rail 601 drives the first slider 603 to move on the electric guide rail 601, and the movement of the first slider 603 synchronously drives the second piston plate 604 to move, so that negative pressure is formed inside the second cylinder 501 to inhale gas from the outside. At the same time, the first slider 603 drives the second slider 605 to move on the guide rail 602 through the second driving rod 607, and the second slider 605 drives the third piston plate 606 to move, squeezing the remaining small amount of liquid in the liquid storage tank 402 into the liquid storage tank 401, and then the electric guide rail 601 drives the first slider 603 to move in the opposite direction. Move, at this time, the first slider 603 will squeeze the gas in the second cylinder 501 through the second piston plate 604 to enter the jet port 502 through the air inlet pipe 503 and be ejected, and the airflow ejected from the jet port 502 can remove the dust on the surface of the millimeter-wave biological radar 103, thereby ensuring the monitoring accuracy of the millimeter-wave biological radar, and the reverse movement of the first slider 603 will also drive the second slider 605 to move in the reverse direction through the second driving rod 607, and the second slider 605 will therefore drive the third piston plate 606 to move in the reverse direction, thereby utilizing the negative pressure principle to achieve the effect of replenishing the liquid in the liquid storage tank 402 from the liquid storage tank 401.

[0050] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
