[0066] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0067] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0068] Example 1, with reference to Figure 1 , which is a first embodiment of the present invention, provides a solenoid valve control mechanism, which includes a signal receiving unit 100 and a control unit 200;

[0069] The signal receiving unit 100 includes a wireless receiver 101 and a wireless transmitter 102 connected to the wireless receiver 101 via wireless communication. The wireless transmitter 102 sends a signal which is received by the wireless receiver 101, so that the wireless receiver 101 can make corresponding instructions.

[0070] The control unit 200 includes a relay 201 electrically connected to the wireless receiver 101, and a solenoid valve 202 connected to the contacts of the relay 201. When the wireless receiver 101 receives a signal and issues a command, it controls the operation of the relay 201. Current flows through the coil of the relay 201, generating a magnetic field that magnetizes the core and attracts the armature. The movement of the armature causes the contacts to switch, opening the normally closed contact and closing the normally open contact. In this device, the signal processed by the wireless receiver 101 controls the energization and de-energization of the relay 201 coil, which in turn controls the opening and closing of the solenoid valve 202 circuit by opening and closing the contacts. When the solenoid coil is energized, it generates an electromagnetic force that overcomes resistance such as spring force, attracting or pushing the valve core to a specific position, thereby changing the state of the fluid channel.

[0071] Among them, the receiving signal band of the wireless receiver 101 is 2.4GHz, which has a high data transmission rate and strong anti-interference ability. When multiple equipment is working in the hospital, such as interference from co-frequency equipment, electrical noise and harmonics, the signal receiving ability of the wireless receiver 101 is not affected, and it can still accurately receive the model of the wireless transmitter 102, thereby timely controlling the solenoid valve 202 to work, and being able to respond to the signal of the wireless transmitter 102.

[0072] Furthermore, it also includes a power supply unit 300, which includes a battery pack 301 and a step-down module 302 connected to the battery pack 301; the battery pack 301 is electrically connected to the relay 201; the step-down module 302 is electrically connected to the wireless receiver 101;

[0073] The battery pack 301 supplies power to the voltage reduction module 302 and the relay 201 . Meanwhile, the voltage reduction module 302 reduces the voltage of the battery pack 301 and supplies power to the wireless receiver 101 .

[0074] The power supply unit 300 further includes a first battery 305 electrically connected to the wireless transmitter 102 , and the first battery 305 provides power for the wireless transmitter 102 .

[0075] Example 2, reference Figure 2 and Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the power supply unit 300 includes an AC power supply 303, a power adapter 304 electrically connected to the AC power supply 303, and a step-down module 302 electrically connected to the power adapter 304; the step-down module 302 is electrically connected to the wireless receiver 101; and the power adapter 304 is electrically connected to the relay 201.

[0076] The AC power supply 303 can convert the AC voltage it outputs into a voltage and current suitable for use with a specific device through the power adapter 304. After conversion, the step-down module 302 and the relay 201 are powered. The step-down module 302 and the power adapter 304 reduce the voltage output to power the wireless receiver 101.

[0077] Furthermore, the power supply unit 300 further includes a battery pack 301; a power adapter 304 is electrically connected to the battery pack 301;

[0078] The battery pack 301 is electrically connected to the step-down module 302 and the relay 201 respectively. As a stored energy source, the battery pack 301 can also supply power to the step-down module 302 and the relay 201 . Meanwhile, the power adapter 304 can charge the battery pack 301 .

[0079] The AC power supply 303 and the battery pack 301 can supply power simultaneously. The AC power supply 303 is a network power supply with a continuous power supply capability. As long as the power grid is stable, it can provide a continuous and stable power supply to the device. There is no problem of battery depletion, which can meet the needs of long-term continuous operation of the device.

[0080] The battery pack 301 is powered by an internal battery and is highly flexible. The device is not bound by a power cord and can be used in places without a mains power supply, such as in the wild, remote areas, or temporary emergency sites. It is easy to move and carry and can meet emergency needs in different scenarios. At the same time, when powered by an AC power supply 303, the battery pack 301 can also be charged, making it convenient for use in emergency situations.

[0088] Furthermore, a partition 403 is provided inside the box body 401, and the partition 403 includes three adjacent sides of a long side close to the box body 401; the partition 403 can be supported and fixed by an extended support column at the bottom of the box body 401, and can also be supported and fixed by a support plate provided on the side of the box body 401. The partition 403 includes three adjacent sides of a long side close to the box body 401, and can be connected or separated from the periphery of the box body 401.

[0089] The accommodating cavity S1 is divided by the partition 403 into a first space S1-1 located below the partition 403, a second space S1-2 located above the side of the partition 403, and a third space S1-3 located on the side of the partition 403.

The end of the air outlet pipe 502 is fixed by the partition 403, so that it is convenient to connect with the partition 403 when in use.

[0091] Two pressure gauges 504 and the pressure reducing valve 501 are installed side by side on the partition 403 and adjacent to the third space S1-3;

[0092] The puncture portion 503a and the gas cylinder 503b are located in the second space S1-2.
