Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples of the present invention without any inventive step, are within the scope of the present invention.
As shown in figure 1, the life support system of a totally-enclosed medical protective clothing comprises a totally-enclosed medical protective clothing with a face mask 22, wherein an air supply hose 6 is arranged in the protective clothing, and the air supply hose 6 is communicated with a main case 3 arranged outside the protective clothing; an air-breathing guide sleeve 2 is arranged on the protective clothing face mask 22 in a sealing way.
Corresponding sensors are arranged at different positions in the protective clothing; a miniature microphone and an earphone 12 are additionally arranged inside the protective clothing at the lower jaw part, and a miniature microphone and a loudspeaker 13 are additionally arranged outside the protective clothing.
The air supply hose 6 has three paths: the first air supply hose 6 is positioned at the rear side of the protective clothing and uniformly extends to the head, and is provided with a downward head air outlet; the second air supply hose 6 is fixed with the head band 5 through the support rod 4, the tail end of the air supply hose 6 is bent upwards and positioned below the nose, and an auxiliary air outlet is positioned in the air guide sleeve 2; the third air supply hose 6 is positioned at the waist part of the protective suit and is provided with an upper air outlet and a lower air outlet;
As shown in fig. 2, the main unit box 3 is a portable sealed box, one side of which is connected with the canister 7 by a screw thread, and the canister 7 is disposable; the other side is connected with a battery box 18 in a plugging and unplugging way, so that the replacement is convenient, and a battery 17 is arranged in the battery box 18; the main case 3 is provided with an air pump 10 and a main control board 19, the main control board 19 is provided with an operating handle 16, and a manual control line is connected with the operating handle 16 for external operation.
The sealed box body is externally provided with an electromagnetic valve 20 and communicated with the interior of the protective clothing through a hose 21 to discharge redundant air in the protective clothing.
An air inlet of the air pump 10 is arranged in the main machine box and communicated with the filter tank 7, and filtered air is supplied to the protective clothing through the air supply pipe 11 by the air pump 10.
The number of the shunting air outlets arranged on the whole body or the half body or the protective clothing of different grades is different, and the corresponding air sensors are different.
Working examples
After the user wears the protective clothing, the operating handle 16 is started, the system self-checks, meanwhile, the ambient air pressure parameters are automatically read and stored, and the air pump 10 is started to work.
After the system is started, the environmental air pressure parameter is immediately stored, the system reads the local altitude air pressure value, the minimum positive pressure difference between the local altitude air pressure value and the minimum positive pressure difference specified in the protective clothing during the working period of the air pump is the minimum safe air pressure in the protective clothing automatically set by the system, and the minimum parameter value automatically adjusted by a user is larger than the minimum safe air pressure.
After the system starts to work, the air is introduced into the three paths of air supply hoses 6 in the protective clothing through the air supply pipe 11 by the air pump 10 after passing through the filtering air tank 7, and the air is output in a shunting way through air outlets of the air supply hoses 6: the head part is downward; the expiration air guide sleeve 2 faces forwards and upwards; the inside of the clothes and trousers faces to all directions. At this point a positive pressure environment is established.
1. The head airflow control process: according to the air pressure default parameters of the head breathing environment set by a manufacturer and the signals sent back by the air pressure sensing chip continuously, the main control board software continuously adjusts the rotating speed of the air pump 10 to continuously maintain the constant positive pressure breathing environment.
When the user uses the air pump, the main control board 19 controls the air pump 10 to work continuously at a constant speed when the head air pressure reaches the default parameters. When the second air pressure sensor 8 detects that the air pressure of the head is lower than the default parameter, the air pump 10 is controlled to increase the air supply quantity; when the second air pressure sensor 8 detects that the head air pressure is higher than the default parameter, the air pump 10 is controlled to reduce the air supply amount, and the head air pressure constant positive pressure state is maintained. When the user needs to increase or decrease the head breathing environment air pressure in the working process, the head breathing air pressure is operated by the operating handle 16 to increase or decrease the size of the key, and the required head air pressure parameter of the breathing environment is adjusted. The main control board 19 replaces the default parameters of the original factory with the new parameters, and the air pressure of the head air is always maintained to keep the constant positive pressure state required by the user by controlling the air supply amount of the air pump 10.
2. Body airflow control process: the main control board 19 continuously adjusts the opening and closing of the electromagnetic valve 20 according to the default parameters of the air pressure of the body environment set by the manufacturer and the signals sent back by the air pressure sensors arranged at the corresponding parts of the body without interruption.
When the output parameters of the first air pressure sensor 1 and the third air pressure sensor 15 arranged at the corresponding positions of the body part airflow exceed the default parameters set by a manufacturer, the main control board software controls the electromagnetic valve 20 to be opened, and excessive air in the clothes and trousers is discharged outwards through the hose 21; after the output parameters of the air pressure sensor return to the default parameters set by the manufacturer, the software of the main control board controls the electromagnetic valve 20 to close, and the air is stopped from being discharged outwards.
When a user needs to increase or decrease the air flow, the air pressure increasing and decreasing keys of the clothes and trousers are operated through the operating handle 16, the main control board software replaces the default parameters of the original factory with the new parameters set by the user, the opening and closing of the electromagnetic valve 20 are controlled, and the state that the clothes and trousers are not bloated and have proper air flow is continuously kept.
3. In operation, the carbon dioxide sensor 14 is always in a monitoring state. The carbon dioxide concentration value does not exceed the standard in the normal state. If the carbon dioxide concentration is monitored to exceed the standard, the buzzer 23 gives an alarm to prompt a user: the exhalation air guide sleeve is righted, and meanwhile, the main control board controls the air pump 10 to improve air supply quantity and ventilate rapidly.
The protective clothing is in a fully closed state, therefore, voice communication is difficult, and the system is convenient to communicate with the outside by additionally arranging a miniature microphone and an earphone 12 in the protective clothing at the lower jaw part and a miniature microphone and a loudspeaker 13 outside.
During the work, only when accidents such as the protective clothing is damaged and leaks air, the air pressure value is lower than the minimum safe air pressure value, and the buzzer 23 gives an alarm to remind a user of timely separating from the polluted environment.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are intended to be covered by the scope of the present invention.
