Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a medical airflow blocking device. Background Art
[0002] At present, many areas of hospitals such as operating rooms and intensive care units are clean areas. When the opening and closing doors of clean areas use doors with airflow blocking functions, the clean effect of clean areas can be improved and the cleanliness of clean areas can be maintained. For example, an airflow blocking door for an operating room disclosed in CN202011323486.4 and an airflow blocking door for an operating room disclosed in CN201510197100.2 are both provided with an air supply structure on the door body. When the door is opened, the air supply structure forms a blocking airflow to prevent external germs from entering the clean area when the door is opened as much as possible. However, in actual applications, when the opening and closing doors of the clean areas of hospitals want to add an airflow blocking function, the old opening and closing doors need to be replaced as a whole, which is costly; and the door with an airflow blocking function integrates the door with the air supply structure. When the air supply structure fails, the opening and closing door needs to be repaired as a whole, which is difficult and time-consuming to repair, and is prone to affecting the normal operation of the hospital, and has a narrow scope of application.
[0003] Based on this, the applicant considered designing a medical airflow blocking device with a wider range of applications. Utility Model Content

[0031] The air extraction base 100 is used to extract external air and convey it into the exhaust column 200. The exhaust column 200 is axially provided with an air outlet 210 for discharging the internal air, so as to form a barrier air flow.
[0032] When this embodiment is in use, the barrier component is placed outside the opening and closing door of the clean area. When the opening and closing door is opened, the air extraction base 100 extracts air from the external environment and conveys the air into the exhaust column 200. The erected exhaust column 200 receives the air from the air extraction base 100. The air inside the exhaust column 200 is discharged through the air outlet 210 provided axially in the column body, forming a barrier air flow barrier outside the door, which can effectively block the entry of external germs and pollutants into the clean area when the opening and closing door is opened; compared with replacing the entire opening and closing door, the medical air flow barrier device of this solution can be used as an additional device, reducing the cost of upgrading the clean area door in the hospital. And because the medical air flow barrier device of this solution does not need to be integrated with the door body, the installation process is simple. When the medical air flow barrier device fails, the difficulty and time for maintenance or replacement are greatly reduced, reducing the risk of interruption of hospital operation caused by maintenance and ensuring the continuity of hospital services; the medical air flow barrier device of this solution can be conveniently moved to different positions, not only applicable to various types of doors, but also can quickly deploy the device to meet emergency situations or temporary needs, with a wide range of applications.

A fan 140 is arranged inside the exhaust base 100, and the air outlet end of the fan 140 is connected to the air outlet 150. When the fan 140 is started, external air enters the inside of the exhaust base 100 through the air inlet, and then the air flow generated by the fan 140 is smoothly transported to the exhaust column 200 by the air outlet end of the fan 140, and finally discharged through the air outlet 210 on the exhaust column 200 to form a blocking air flow. Specifically, the fan 140 can adopt a booster fan 140 in the prior art to ensure that the air outlet 210 can discharge a high-speed and stable air flow to form an effective block.
[0034] Preferably, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a filter net 110 is arranged at the air inlet, and a filter plate 120 is arranged between the air inlet and the fan 140.

The filter net 110 located at the air inlet is used for initially filtering the air entering the exhaust base 100, while the filter plate 120 located between the air inlet and the fan 140 further purifies the air to improve the cleanliness of the blocking air flow. The opening on the top side of the exhaust base 100 facilitates the insertion and replacement of the filter plate 120, which is convenient for regular maintenance and cleaning to ensure the filtering effect. The limiting block 121 inside the base is used for fixing both ends of the filter plate 120 to ensure that the filter plate 120 will not shift under the action of the air flow.

Specifically, a rubber sealing layer can be arranged on the outer side wall of the connecting convex port 230 to make the connection between the connecting convex port 230 and the air outlet 150 closer.
[0036] Preferably, as Figure 3As shown, a weight block 160 is fixedly connected to the inside of the exhaust base 100; when the fan 140 is running, a certain vibration may be generated, and the wind force generated by the exhaust port may also cause the exhaust base 100 to move. The weight block 160 can increase the weight of the exhaust base 100, and can avoid the exhaust base 100 from tipping over due to movement or vibration as much as possible.

[0039] Preferably, if Figure 2As shown, a suction base 100 is installed with a human body sensing unit 170 and a control unit 130. The control unit 130 is communicatively connected to the human body sensing unit 170 and a blower 140. When the human body sensing unit 170 senses a human body approaching the barrier assembly, the controller controls the blower 140 to start. When the human body sensing unit 170 senses a human body moving away from the barrier assembly, the controller controls the blower 140 to turn off. When the human body sensing unit 170 detects that a person is approaching the barrier assembly, the control unit 130 receives the sensing signal and then sends an instruction to the blower 140 to start it, forming a barrier air flow. When the human body sensing unit 170 detects that a person has left the barrier assembly by a certain distance, the control unit 130 receives the sensing signal again and controls the blower 140 to turn off to save energy. Through the human body sensing unit 170 and the control unit 130, the blower 140 can be started only when needed, which can reduce energy consumption, improve energy use efficiency, reduce the need for manual operation, reduce the possibility of operation errors, and improve the convenience of use. Specifically, the above human body sensing unit 170 can adopt an infrared or microwave sensor in the prior art.

The two ends of the top connecting member 300 are respectively fixedly connected to the tops of the exhaust columns 200 of the two barrier assemblies. The two spaced components are connected by the top connecting member 300, making the medical air flow barrier device as a whole in an arch shape to enhance the structural stability of the entire device.
