The control module 81 will receive and analyze the pressure sensing signal, the tilt sensing signal and the brightness signal. The control module 81 will analyze the pressure sensing signal to obtain a pressure value, and when it is determined that the pressure value is less than a first threshold, it will control the warning unit 6 to issue the warning message. Specifically, when the drip stand of the present invention is not in use and is in an upright state, the pressure sensors 71 will be subject to the downward gravity of the stand unit 1 to generate the pressure sensing signal. Once the drip stand of the present invention tilts, the force sensed by the pressure sensors 71 decreases, and the control module 81 controls the buzzer 61 of the warning unit 6 when the pressure value is less than the first threshold. Sound an alert.

The control module 81 will also analyze the tilt sensing signal to obtain a tilt angle when the pressure value of the pressure sensing signal is greater than a second threshold, and will control the warning when the tilt angle is greater than a predetermined angle. Unit 6 issues the warning message. Specifically, when the drip stand of the present invention is held by a user, the pressure sensors 71 will be affected by the downward gravity of the stand unit 1 and the force of the user's holding and pressing down, thereby generating the pressure sensing. signal. During the user's grasping process, the control module 81 will analyze the tilt sensing signal to send out different warning messages according to different tilt degrees. The predetermined angle is, for example, but not limited to 15 degrees or 15 degrees. 30 degrees. In this embodiment, when the tilt angle is greater than 15 degrees, the control module 81 will control the warning light 62 to flash once per second, and when the tilt angle is greater than 30 degrees, the control module 81 will control the warning Light 62 flashes twice per second.

The control module 81 will control the lighting unit 5 to start when the ambient brightness represented by the brightness signal is less than a predetermined brightness and the pressure value of the pressure sensing signal is greater than the second threshold, and will adjust the lighting unit 5 according to the brightness signal. The luminous intensity of the lighting unit 5.

The input module 82 is connected to the control module 81 with signals and is operable to set the first threshold, the second threshold, the predetermined angle and the predetermined brightness.

When the drip stand of the present invention is not in use, the stand unit 1 is upright and will produce a downward pressing force on the pressure sensors 71. The pressure sensors 71 will sense the force and generate the force. pressure sensing signal. When the drip stand of the present invention is tilted, the relative positions of the stand unit 1 and the pressure sensors 71 change, that is, the pressure sensors 71 are no longer located below the stand unit 1 , so the pressure value of the pressure sensing signal will gradually become smaller or even zero. During this process, the control module 81 determines that when the pressure value is less than the first threshold, it controls the buzzer 61 to sound an alarm.

When the drip stand of the present invention is used, since the user is holding the pole 15, the pressure sensors 71 will sense the weight of the stand unit 1 and press down when the user is holding it. force to generate the pressure sensing signal. If the user's gait becomes unstable, the frame unit 1 will be caused to tilt, causing the tilt sensor 72 to sense the tilt sensing signal. During this process, the control module 81 will send out different warning messages according to different degrees of tilt, so as to help medical staff know the severity of the tilt.

In addition, when the surrounding environment is dark, the control module 81 will control the lighting unit 5 to start, and adjust the luminous intensity of the lighting unit 5 according to the brightness of the environment. That is to say, when the environment is darker, the luminous intensity of the lighting unit 5 will be stronger.

In addition, if the user needs to pay attention to care matters, the medical staff can operate the lever 36 of the sign unit 3 to rotate the prompt image 37 to the viewing window 331 . It should be noted that the prompt image 37 is, for example, but not limited to images of fasting, prevention of falling, etc. In addition, in this embodiment, one flag unit 3 is provided for explanation, but during implementation, two or more flag units 3 may also be provided.

It should be noted that in this embodiment, the power supply unit 4, the tilt sensor 72, and the control unit 8 are disposed on the base 11, but they may also be disposed on the frame module 12 during implementation. In addition, the light sensor 73 is disposed on the vertical pole 15, but may also be disposed on the hanging rod 16 during implementation, and is not limited to the description in this embodiment.

Furthermore, in this embodiment, the number of the pressure sensors 71 is four and they are respectively arranged on the four rolling units 2 . However, in other embodiments of the present invention, they can also be designed as only one pressure sensor. The sensor 71 is installed on one of the rolling units 2 .

In addition, the way in which the control module 81 controls the warning unit 6 to send out the warning message is not limited to that described in this embodiment. For example, but not limited to, the buzzer 61 is used in conjunction with the warning light 62 .

To sum up, the at least one pressure sensor 71 can sense the downward pressing of the frame unit 1 to generate a pressure sensing signal, and the control unit 8 will analyze and determine the pressure sensing signal to send out The warning message is designed to notify medical staff as soon as possible when the user is unsteady in walking or falls, causing the frame unit 1 to tilt or even fall over. Furthermore, through the design of the tilt sensor 72, when the user walks unsteadily or falls and the frame unit 1 tilts or falls, different warnings can be issued according to the inclination degree of the frame unit 1. message. In addition, by sensing the ambient brightness through the light sensor 73 and matching the design of the lighting unit 5, appropriate lighting can be actively provided when the ambient brightness is insufficient to improve the safety of the user's movement. In addition, the design in which medical staff can operate the lever 36 to decide whether to reveal the prompt image 37 can quickly understand the user's care matters, which is very convenient and is a very innovative and practical creation. Therefore, it can indeed achieve the purpose of the present invention.
