This practicality is existing has following beneficial effect: the speed and pressure of the gas exhaled by the person are utilized to discharge the gas to the external environment without the assistance of power equipment.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a negative pressure absorption formula valve.
Background
Along with the higher and higher requirement of the patient on the comfort level of the operation, the concept of utilizing the laughing oxygen mixed gas to realize analgesia and tranquilization in the operation process is gradually accepted by people, and the corresponding laughing oxygen analgesia instrument is gradually adopted by hospitals. However, in the use process of the laughing oxygen analgesia apparatus, medical staff need the patient to completely exhaust the exhaled waste gas out of the operating room, and ensure the patient to breathe in the mouth during burn treatment and cosmetic surgery. The current medical care personnel wear the breathing mask on the human body, then connect two pipes on the breathing mask, one pipe is communicated with the laughing oxygen analgesia instrument, the other pipe is connected with the vacuum pump, and the vacuum pump is utilized to discharge the waste gas in the breathing mask to the environment.
And the vacuum pump is used for pumping air, so that the energy consumption is high. Studies have shown that the gas exhaled by a person (mouth or nose) is itself a stream of gas having a velocity and the pressure of this stream is above atmospheric pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem, a negative pressure absorption formula valve is proposed.
The utility model adopts the following technical scheme:
a negative pressure absorption type valve comprises an air outlet pipe, an air inlet pipe, a compensating pipe, a connecting pipe and a valve block, wherein two ends of the connecting pipe are respectively communicated with the air inlet pipe and the compensating pipe; when no gas enters from the gas inlet pipe, the compensating pipe is communicated with the gas outlet pipe, and the valve block cuts off the communication of the gas inlet pipe with the gas outlet pipe and the compensating pipe; when gas enters from the gas inlet pipe, the valve block moves and is communicated with the gas inlet pipe and the gas outlet pipe, and the valve block cuts off the communication between the compensating pipe and the gas outlet pipe as well as the gas inlet pipe; when gas stops entering the gas inlet pipe, the valve block returns to the position before the valve block starts to move, the valve block cuts off the communication between the gas inlet pipe and the gas outlet pipe and the compensation pipe, and the compensation pipe is communicated with the gas outlet pipe.
When the valve is used, one end of the air inlet pipe is directly or indirectly communicated with the mouth of a person, so that the exhaled air of the person enters the air inlet pipe, and the air outlet pipe is communicated with the atmospheric environment through the compensating pipe;
when no gas is exhaled, the compensating pipe is communicated with the gas outlet pipe, and the valve block cuts off the communication of the gas inlet pipe with the gas outlet pipe and the compensating pipe;
when a person begins to exhale gas, the valve block moves and is communicated with the gas inlet pipe and the gas outlet pipe, and the valve block cuts off the communication between the compensating pipe and the gas outlet pipe as well as the gas inlet pipe;
when the gas exhaled by a person is reduced to almost no exhalation, the air pressure on one side of the air inlet pipe is reduced, the valve block returns to the position before the valve block starts to move, the valve block cuts off the communication between the air inlet pipe and the air outlet pipe and the compensation pipe, and the compensation pipe is communicated with the air outlet pipe.
The device discharges the gas to the external environment by utilizing the speed and the pressure of the gas exhaled by people, and power equipment is not needed for assistance.
Optionally, the connecting pipe is an arc-shaped connecting pipe, and the valve block is a spherical valve block.
Optionally, the air inlet pipe is arranged at one end of the connecting pipe.
Optionally, the compensation pipe is fixed at one end of the connection pipe.
Optionally, the air outlet pipe is fixed on the compensating pipe, and the compensating pipe is perpendicular to the air outlet pipe.
Optionally, the air inlet pipe is a circular pipe-shaped air inlet pipe.
Optionally, the compensating pipe is a circular pipe-shaped compensating pipe.
Optionally, the air outlet pipe is a circular pipe-shaped air outlet pipe.
The diameter of the specific air outlet pipe is smaller than that of the valve block.
The utility model has the advantages that: the speed and pressure of the gas exhaled by the person are utilized to discharge the gas to the external environment without the assistance of power equipment.
Description of the drawings:
figure 1 is a schematic diagram of the construction of a negative pressure absorption valve.
The figures are numbered: 1. valve block, 2, intake pipe, 3, outlet duct, 4, connecting pipe, 5, compensating pipe.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, a negative pressure absorption valve includes a spherical valve block 1, a circular pipe-shaped air inlet pipe 2, a circular pipe-shaped air outlet pipe 3, an arc-shaped connecting pipe 4 and a circular pipe-shaped compensating pipe 5. Intake pipe 2 and compensating pipe 5 are fixed respectively at two mouths of pipe of connecting pipe 4, and valve block 1 slides and sets up in connecting pipe 4, and valve block 1 can slide in connecting pipe 4 and compensating pipe 5, and one section pipe diameter that connecting pipe 4 and intake pipe 2 meet is less, and valve block 1 can't be by in connecting pipe 4 slip intake pipe 2, and the diameter of valve block 1 is greater than the diameter of outlet duct 3.
The operation of the apparatus will now be described in detail with reference to the accompanying figure 1
When no gas is exhaled, the compensating pipe 5 is communicated with the air outlet pipe 3, and the valve block 1 cuts off the communication between the air inlet pipe 2 and the air outlet pipe 3 as well as the compensating pipe 5;
when a person begins to exhale gas, the valve block 1 moves upwards and is communicated with the gas inlet pipe 2 and the gas outlet pipe 3, and the valve block 1 blocks the communication between the compensating pipe 5 and the gas outlet pipe 3 and the gas inlet pipe 2;
when the gas exhaled by a person is reduced to almost no gas exhaled, the air pressure on one side of the air inlet pipe 2 is reduced, the valve block 1 moves downwards and returns to the position before the valve block starts to move, the valve block 1 cuts off the communication between the air inlet pipe 2 and the air outlet pipe 3 and the compensation pipe 5, and the compensation pipe 5 is communicated with the air outlet pipe 3.
