[0002] Medical negative pressure suction systems are widely used in various departments and wards of hospitals to suction sputum for patients and to suction pus, blood, ascites, etc. during surgery. The basic principle of the medical negative pressure suction system is to form a negative pressure environment through the central negative pressure station equipment, connect to the gas terminals of various clinical gas points in the entire hospital through a closed pipeline system, and maintain a constant negative pressure state throughout the day.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0019] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0020] This embodiment provides a linkage cleaning system for negative pressure pipelines, the principle of which is: the gas pressure sensor collects the vacuum pressure of each pipe section and transmits it to the central controller, the central controller analyzes the pressure difference to determine the blockage of each pipe section, and then uses an ultrasonic cleaner to clean the blocked pipe, so that the material adhering to the inner wall of the pipe is detached. After that, compressed air is used as the air source to input into the pipeline for flushing, and the detached materials in each pipeline are quickly dispersed and transported to the main pipeline for collection, thereby achieving the purpose of unblocking the pipeline.

[0021] See also Figure 1 The system may include: a central controller 1, a gas pressure alarm 2, an ultrasonic cleaner 3, a compressed air assembly 4, a main pipeline 5 and a branch pipeline 6. The central controller 1 is electrically connected to the gas pressure alarm 2, the ultrasonic cleaner 3, and the compressed air assembly 4 respectively. The ultrasonic cleaner 3 is connected to the branch pipeline 6. A plurality of vacuum suction terminals 7 are connected in series on the branch pipeline 6 (the vacuum suction terminals 7 are used to collect and process human waste liquid deposits, which can greatly improve the reliability and safety of the operation of the hospital life support system). The gas output end of the compressed air assembly 4 is connected to the gas input end of the branch pipeline 6.

[0022] The central controller 1 receives the signal transmitted from the gas pressure alarm 2 and gives feedback. For example, the signal transmitted by the gas pressure alarm 2 can be an alarm signal to instruct the central controller 1 to start the cleaning work. Among them, when the gas pressure alarm 2 generates an alarm signal and transmits the alarm signal to the central controller 1, the central controller 1 sends a cleaning instruction to the ultrasonic cleaner 3. The ultrasonic cleaner 3 starts the cleaning work according to the cleaning instruction to clean the branch pipe 6 connected to it and the pipeline where the vacuum suction terminal 7 is located, so that the residue in the pipeline is separated from the inner wall. Then, the central controller 1 issues an instruction to the compressed air assembly 4, so that the compressed air assembly 4 inputs compressed air into the branch pipe 6 connected to it and the pipeline where the vacuum suction terminal 7 is located, and the residue separated from the branch pipe 6 is flushed into the main pipe 5 connected to it by compressed air. The main pipe 5 then transports it to the negative pressure suction riser 8 connected to it and stores it through the storage device.

[0023] The system provided by the utility model can solve the problem of pipeline blockage so that the entire system forms a passage. Based on the above process, the existing compressed air system of the hospital is effectively used as the air source, and the compressed air is used for flushing to quickly disperse the objects adhering to the vacuum suction terminal 7 and the inner wall of each pipeline. In addition, it is easy to maintain. A needle valve 9 is provided on the branch pipeline 6, and the needle valve 9 is provided on the side close to the ultrasonic cleaning instrument 3.

[0024] In the above process, the gas pressure alarm 2 may include two branches, such as a first branch and a second branch. The first branch is connected to the branch pipeline 6, and the second branch is connected to the main pipeline 5. The gas pressure alarm 2 is used to collect the pressure signals on the branch pipeline 6 and the main pipeline 5 and transmit them to the central controller 1, and then the central controller 1 analyzes the pressure difference between the branch pipeline 6 and the main pipeline 5. If the pressure difference reaches the threshold value preset by the central controller 1, the central controller 1 sends a command to the ultrasonic cleaner 3 to control the ultrasonic cleaner 3 to start working.

[0025] In the present invention, the threshold value preset in the central controller 1 can be set according to actual application conditions, and the embodiments of the present invention do not limit this.

[0026] In the specific implementation process, a gas pressure sensor 10 is provided on the first branch and the second branch to collect the pressure signals on the main pipeline 5 and the branch pipeline 6. In addition, a maintenance valve 11 is provided on the first branch and the second branch. In order to maintain the normal operation of the entire system, the gas pressure sensor 10 and the maintenance valve 11 are always in an open state.

[0027] In the specific implementation process, the compressed air assembly 4 includes a compressed air input pipe 4a and a gas mass flow meter 4b, a solenoid valve 4c and a gas pressure regulating valve 4d arranged on the compressed air input pipe 4a.

[0028] Among them, the gas mass flow meter 4b is used to measure the compressed air flow on the compressed air input pipe 4a in real time. When the ultrasonic cleaning device 3 completes the ultrasonic vibration cleaning according to the set time, the central controller 1 starts the solenoid valve 4c, so that the solenoid valve 4c releases the compressed air within the set time, that is, the opening and closing of the compressed air input pipe 4a is controlled by the solenoid valve 4c. When the set time for releasing the compressed air is reached, the central controller 1 issues a closing instruction to the solenoid valve 4c.

[0029] The gas pressure regulating valve 4d is used to control the pressure of the compressed air entering the compressed air input pipe 4a. The central controller 1 is electrically connected to the gas mass flow meter 4b and the solenoid valve 4c, respectively, that is, the opening and closing of the compressed air input pipe 4a and the flow rate of the compressed air on the compressed air input pipe 4a are controlled by the central controller 1.

[0030] There are two branches between the compressed air input pipe 4a and the central controller 1, and both branches are provided with a maintenance valve 11 and a gas pressure sensor 10. Among them, one branch is used to measure the gas pressure of the pipe section between the gas mass flowmeter 4b and the solenoid valve 4c on the compressed air input pipe 4a, and the other branch is used to measure the gas pressure at the gas input end of the compressed air input pipe 4a. The amount and inflow time of the compressed air flowing into the system are monitored in real time by the central controller 1. When the central controller 1 receives the pressure information transmitted from the gas pressure alarm 2 and analyzes it, it determines the need to clean and purge each pipeline again. If the pressure difference analyzed by the central controller 1 does not meet the set pressure difference threshold requirement, the above operation is repeated until it is cleaned.

[0031] In more detail, for the convenience of maintenance, two maintenance valves 11 are further provided on the compressed air input pipe 4a, and are respectively located at the gas input end and the gas output end of the compressed air input pipe 4a.

[0032] In this embodiment, the main pipeline 5 can be a negative pressure suction pipeline.

[0033] The gas pressure alarm 2 can be selected from the YQJ series, YQ J-2, etc. manufactured by Hangzhou Lihua Technology Co., Ltd.

[0034] The gas mass flow meter 4b can be MF5700 gas mass flow meter 4b produced by Guangzhou Dichuan Instrument Co., Ltd.

[0035] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.
