Description

Technical Field

[0001] This utility model relates to the field of medical gas supply technology, specifically a medical gas supply guarantee device for a life support zone. Background Technology

[0002] Medical gas supply systems are an indispensable infrastructure of modern hospitals, responsible for providing continuous and stable medical gases to various areas such as general wards, operating rooms, and ICUs. Currently, such systems typically use a unified pipeline network for medical gas distribution. However, when the system encounters emergencies such as a drop in pressure at the medical gas supply source or a surge in gas consumption in critical areas like operating rooms and ICUs, the pressure and flow rate of medical gases across the entire pipeline network will generally decrease. This can lead to competition between routine gas usage in non-critical areas and emergency gas usage in critical areas, making it impossible to prioritize the supply of medical gases for critical procedures such as surgery and the treatment of critically ill patients, posing significant medical safety risks. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a medical gas supply guarantee device for the life supply area.

[0004] The technical solution of this utility model is as follows: A medical gas supply guarantee device for a life support zone, comprising: The air distribution cylinder has its air inlet connected to a medical air source; The gas supply line in the life supply area is connected to the gas distribution cylinder. A flow meter is connected in series on this line to detect the gas flow rate in the line. At least one non-life supply gas pipeline is connected to the gas distribution cylinder, and a pipeline valve is connected in series on the pipeline. A pressure transmitter, connected to the air distribution cylinder, is used to detect the air pressure inside the air distribution cylinder in real time; The control unit connects to the pressure transmitter, flow meter, and pipeline valves; When the control unit determines, based on the signal from the flow meter, that the gas flow rate in the gas supply pipeline of the life supply area exceeds the set upper limit, or when it determines, based on the signal from the pressure transmitter, that the gas pressure in the gas distribution cylinder is lower than the set lower limit, the control unit can control the pipeline valve to close.

[0005] Preferably, the control unit includes a pneumatic controller and a circuit controller, the pipeline valve is a pneumatic valve, the pneumatic controller is connected to the pipeline valve through an air pipe, and the circuit controller is electrically connected to the pneumatic controller, the pressure transmitter and the flow meter.

[0006] Furthermore, the pneumatic controller is connected to the air distribution cylinder via an air pipe.

[0007] Furthermore, a filter is connected in series on the air pipe between the pneumatic controller and the air distribution cylinder.

[0008] Preferably, it also includes an alarm unit electrically connected to the circuit controller.

[0009] Furthermore, the control unit triggers the alarm unit while closing the control pipeline valve.

[0017] like Figure 1 As shown, an embodiment of this utility model provides a medical gas supply guarantee device for the life supply area, including a gas distribution cylinder 1, a life supply area gas supply pipeline 3, a non-life supply area gas supply pipeline 5, a pressure transmitter 2, and a control unit 7.

[0018] The air inlet of the gas distributor 1 is connected to a medical gas source (not shown in the figure) for receiving and distributing medical gases. The medical gas source is generally medical air or oxygen, and depending on the type of gas supplied, an air compressor, oxygen generator, or liquid oxygen tank may be used as the medical gas source.

[0019] The inlet of the gas supply line 3 in the life support area is connected to the gas distribution cylinder 1, and the outlet extends to life support areas such as the operating room and ICU, connecting to the corresponding medical devices. A flow meter 4 is connected in series on the gas supply line 3 in the life support area to detect the gas flow in the line in real time and convert it into a signal to be sent to the control unit 7.

[0020] The inlet of the non-life-sustaining gas supply line 5 is connected to the gas distribution cylinder 1, and the outlet extends to non-life-sustaining areas such as general wards and observation rooms, connecting to the corresponding medical devices. A pipeline valve 6 is connected in series on this non-life-sustaining gas supply line 5. The pipeline valve 6 is connected to the control unit 7 and is opened and closed under the control of the control unit 7.

[0021] Gas distribution cylinder 1 distributes medical gas to both the life-sustaining and non-life-sustaining areas via life-sustaining area gas supply line 3 and non-life-sustaining area gas supply line 5. At least one non-life-sustaining area gas supply line 5 can be connected to gas distribution cylinder 1, such as... Figure 1 As shown, in this embodiment, there are two gas supply lines 5 for non-life supply areas. The pipeline valves 6 on the two gas supply lines 5 for non-life supply areas are connected to the control unit 7 and can be opened and closed independently.

[0022] The pressure transmitter 2 is directly installed on the gas distribution cylinder 1, and its detection end is connected to the inside of the gas distribution cylinder 1. It is used to detect the changes in air pressure inside the gas distribution cylinder 1 in real time and convert them into signals to be sent to the control unit 7.

[0023] The control unit 7 includes a pneumatic controller 71 and an electrical controller 72. Correspondingly, the pipeline valve 6 is a pneumatic valve. The pneumatic controller 71 is connected to the pipeline valve 6 via an air pipe, and the electrical controller 72 is electrically connected to the pneumatic controller 71, the pressure transmitter 2, and the flow meter 4. The control unit 7 controls the opening and closing of the pipeline valve 6 through the pneumatic controller 71 based on the signals transmitted by the pressure transmitter 2 and the flow meter 4.

[0024] The pneumatic controller 71 is responsible for pneumatic circuit control, and the circuit controller 72 is responsible for signal processing, logic judgment, and issuing control signals.

[0025] In this embodiment, the use of a pneumatic valve as pipeline valve 6 and the dual control architecture combining a pneumatic controller 71 and a circuit controller 72 are to ensure the safety of medical gas supply, especially when supplying oxygen. The opening and closing of the pipeline is controlled by pneumatic control, while the potentially dangerous circuit control is kept away from or isolated from the gas distribution environment to avoid dangers such as explosions and fires.

[0026] The pneumatic controller 71 is also connected to the air distribution cylinder 1 via an air pipe to obtain a stable air source power. Using the air distribution cylinder 1 as the pneumatic power source avoids the need for an additional pneumatic air source mechanism, thus simplifying the structure of the device.

[0027] Furthermore, a filter 8 is connected in series on the air pipe between the pneumatic controller 71 and the air distribution cylinder 1 to filter out impurities that may be mixed in the gas, ensuring the long-term stable operation of the pneumatic components.

[0028] To optimize the performance of the device, the present invention has made an optimized design in terms of structural layout. The interface of the air supply pipeline 3 in the life supply area on the air distribution cylinder 1 is closer to the air inlet of the air distribution cylinder 1 than the structure of the air supply pipeline 5 in the non-life supply area. This arrangement can prioritize the air supply pressure of the life supply area when the pressure fluctuates within the device.

[0029] In addition, the device also includes an alarm unit 9, which is electrically connected to the circuit controller 72. When the circuit controller 72 controls the pipeline valve 6 to close via the pneumatic controller, the alarm unit 9 is triggered. The alarm unit 9 supports multiple alarm modes. In this embodiment, it supports, but is not limited to, audible and visual alarms and / or SMS alarms and / or telephone alarms, ensuring that management personnel can grasp the abnormal situation of the device as soon as possible.

[0030] Under normal gas supply conditions, the pressure transmitter 2 monitors the gas pressure in the gas distribution cylinder 1 in real time, the flow meter 4 monitors the gas flow in the gas supply pipeline 3 of the life supply area in real time, and the control unit 7 is in standby mode.

[0031] When the circuit controller 72 determines, based on the signal from the flow meter 4, that the gas flow rate in the gas supply pipeline 3 of the life-sustaining area exceeds the set upper limit, or based on the signal from the pressure transmitter 2, that the gas pressure in the gas distribution cylinder 1 is below the set lower limit, the circuit controller 72 sends a signal to the pneumatic controller 71. The pneumatic controller 71 then controls the pipeline valve 6 to close, cutting off the gas supply to the non-life-sustaining area and ensuring a continuous and stable gas supply to the life-sustaining area. Simultaneously, the circuit controller 72 triggers the alarm unit 9, issuing an alarm signal.

[0032] The values ​​of the upper and lower limits mentioned above can be set and adjusted by the circuit controller 72.

[0033] This invention utilizes intelligent monitoring and control to automatically cut off gas supply to non-life-sustaining areas when insufficient pressure or excessive gas consumption in life-sustaining areas occurs, prioritizing the medical gas supply to life-sustaining areas such as operating rooms and ICUs, effectively improving the safety and reliability of the medical gas supply system. Furthermore, a dual protection mechanism is employed: monitoring the gas flow rate in the life-sustaining area and monitoring the gas pressure within the gas distribution cylinder 1. Abnormalities in either parameter trigger the protection mechanism, further enhancing the device's reliability.
