Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the invention provides a humidification device of a respiratory support device, comprising a box body, wherein a water replenishing chamber 1 and a humidification chamber 2 are arranged in the box body in a partitioned manner, and the water replenishing chamber 1 is communicated with the humidification chamber 2 through a pressure balance channel 3; the water replenishing chamber 1 replenishes water into the humidifying chamber 2 in a storage type or/and intravenous injection mode, wherein:
the top end of the water replenishing cavity 1 is provided with a water replenishing port 4, and the bottom of the water replenishing cavity is communicated with the humidifying cavity 2 through a communicating hole 5;
the water replenishing cavity 1 is also provided with an intravenous injection port 6, a floating ball 7 is arranged in the water replenishing cavity, and the floating ball 7 can be far away from or close to the intravenous injection port 6;
a heating device 8 is arranged in the humidification chamber 2. Optionally, the heating device 8 is a metal heating plate, and is disposed at the bottom of the humidification chamber 2 for conducting heat, so that the temperature of the water inside the humidification chamber 2 rises and evaporates, and further is used for user side spray humidification.
When the breathing support equipment works, the water in the humidification chamber 2 is continuously heated; when the water in the humidification chamber 2 is heated and evaporated, the water level will drop and the pressure in the humidification chamber 2 will increase. At this time, the pressure of the humidification chamber 2 is greater than the pressure of the water replenishing chamber 1, and the water in the water replenishing chamber 1 cannot flow to the humidification chamber 2, so that the water cannot be automatically replenished to the humidification chamber 2. In this scheme, through 3 intercommunications of pressure balance passageway between moisturizing cavity 1 and the humidifying cavity 2, guarantee that the pressure between two cavities equals, the hydroenergy of moisturizing cavity 1 passes through 5 normal flow direction humidifying cavities 2 of intercommunicating pore, for 2 moisturizing of humidifying cavities.
In this embodiment, the water replenishing chamber 1 can dynamically replenish water to the humidification chamber 2 through three water replenishing schemes: the water replenishing method comprises a storage type water replenishing mode and an intravenous injection water replenishing mode, or the storage type water replenishing mode and the intravenous injection water replenishing mode simultaneously replenish water. In this embodiment, the water in the water replenishing chamber 1 and the humidifying chamber 2 is purified water.
The first scheme is as follows: storage type water replenishing mode
The top end of the water replenishing cavity 1 is provided with a water replenishing port 4, and the bottom of the water replenishing cavity is communicated with the humidifying cavity 2 through a communicating hole 5; during water storage, water is injected into the water replenishing cavity 1 through the water replenishing port 4 to reach a water level L1.
When the breathing support equipment works, water in the humidification chamber 2 evaporates, water in the water replenishing chamber 1 flows to the humidification chamber 2 through the communication hole 5, dynamic water replenishing is carried out on the humidification chamber 2, and the water replenishing is stopped when reaching a water level L2.
Scheme II: water replenishing mode for intravenous injection
Referring to fig. 2, the water replenishing chamber 1 is further provided with an intravenous injection port 6, a floating ball 7 is arranged in the intravenous injection port 6, and the intravenous injection port 6 is positioned above the floating ball 7. One end of the intravenous injection port 6 is connected with the intravenous transfusion soft bag through a transfusion tube, and the liquid in the intravenous transfusion soft bag flows to the water replenishing cavity 1 through the intravenous injection port 6. When the water level L3 in the water replenishing chamber 1 rises, the buoyancy of the floating ball 7 is larger than the self gravity, the floating ball 7 gradually rises to be close to the intravenous injection port 6 until the intravenous injection port 6 is blocked, and the water in the water replenishing chamber 1 and the water in the humidifying chamber 2 reach dynamic balance. In the process, water in the water replenishing chamber 1 continuously flows to the humidifying chamber 2 through the communication hole 5 to dynamically replenish water for the humidifying chamber 2.
The water in the humidification chamber 2 is heated and evaporated by the heating device 8, and the water level L4 gradually drops. The water in the water replenishing cavity 1 is used for replenishing water for the humidifying cavity 2, the water level L3 also gradually drops, and the floating ball 7 gradually keeps away from the intravenous injection port 6 along with the drop of the water level until the liquid in the intravenous transfusion soft bag flows to the water replenishing cavity 1 through the intravenous injection port 6. The water level L3 in the refill chamber 1 gradually rises and the float 7 gradually approaches the iv port 6 again. Circulating in this way, the water replenishing chamber 1 is used for dynamically replenishing water for the humidifying chamber 2. The water replenishing mode through intravenous injection is not limited by the capacity of the water replenishing cavity 1, and the integral structure of the humidifying device is simplified.
The third scheme is as follows: water replenishing is simultaneously carried out in a storage type water replenishing mode and an intravenous injection water replenishing mode
The water is simultaneously supplemented into the water supplementing cavity 1 through the water supplementing port 4 and the intravenous injection port 6, the water supplementing efficiency is improved, the limitation of the capacity of the water supplementing cavity 1 is avoided, and the integral structure of the humidifying device is simplified. In a hospital, water is supplemented in a mode of hanging a water bottle or a water bag and other soft venous transfusion bags, when a patient does not have a hanging device, the water supplementing time of the humidification chamber 2 is prolonged through storage type water supplementing, and the application scene is more flexible.
In the technical scheme, the water replenishing cavity 1 and the humidifying cavity 2 are arranged in a partitioned mode, and the floating ball 7 is located in the water replenishing cavity 1. Compared with the prior art, the scheme that the floating ball 7 and the humidifying chamber 2 are positioned in the same water storage tank is adopted. In the scheme, the floating ball 7 and the humidifying chamber 2 are arranged in a partitioning mode, so that the floating ball 7 is prevented from being burnt out by the humidifying chamber 2 under the condition of empty burning, and the service life of the whole humidifying device is prolonged.
According to the humidification device of the respiratory support equipment, the water replenishing chamber 1 and the humidification chamber 2 are arranged in a partitioning manner, so that water in the humidification chamber 2 can be heated to the specified humidification temperature in a short time, and the floating ball 7 can be prevented from being burnt out under the condition that the humidification chamber 2 is burnt out. The water replenishing cavity 1 can replenish water in a storage type water replenishing mode and an intravenous injection water replenishing mode or in both the storage type water replenishing mode and the intravenous injection water replenishing mode, so that the water replenishing time of the humidification cavity 2 is prolonged, and application scenes with different requirements are met.
Referring to fig. 3, in this solution, as a further improvement of the above technical solution, the pressure balance channel 3 includes a pressure balance pipe 9, the pressure balance pipe 9 includes an upper pipe orifice 91 and a lower pipe orifice 92, the upper pipe orifice 91 is communicated with the moisturizing chamber 1, and the lower pipe orifice 92 is level with the water level L6 of the humidification chamber 2.
Specifically, the pressure balance pipe 9 includes an upper pipe orifice 91 and a lower pipe orifice 92, the upper pipe orifice 91 is communicated with the water replenishing chamber 1, the lower pipe orifice 92 extends to the bottom of the humidification chamber 2, and when the level of the water level L6 of the humidification chamber 2 is maintained, the water level L5 of the water replenishing chamber 1 and the water level L6 of the humidification chamber 2 reach dynamic balance.
In the scheme, the water replenishing chamber 1 is communicated with the humidifying chamber 2 through the pressure balancing channel 3, so that the pressure between the two cavities is balanced, and the aim of normally replenishing water is fulfilled. The pressure equalization channel 3 may be selected from a variety of implementable configurations.
The first embodiment is as follows:
the water replenishing chamber 1 and the humidifying chamber 2 are arranged in a partitioned mode through a division plate, the division plate is provided with mounting holes, and the pressure balance pipe 9 is mounted on the division plate through the mounting holes.
The upper pipe mouth 91 of the pressure balance pipe 9 extends to the upper part of the water level of the moisturizing chamber 1, and the lower pipe mouth 92 extends to be level with the water level of the humidifying chamber 2.
When the respirator works, the water replenishing chamber 1 and the humidifying chamber 2 are both in a closed state, so that dust is prevented from entering the chambers to pollute humidifying water. The water replenishing cavity 1 replenishes water through a water replenishing port 4 and a vein injection port 6. The upper pipe orifice 91 of the pressure balance pipe 9 extends to the upper part of the water level surface of the water replenishing chamber 1, the lower pipe orifice 92 extends to be kept level with the water level surface of the humidifying chamber 2, a negative pressure area is formed between the upper part of the water level surface of the water replenishing chamber 1 and the top of the water replenishing chamber 1, and the negative pressure can absorb the water in the water replenishing chamber 1. At this time, the pressure and the water level of the water replenishing chamber 1 and the humidifying chamber 2 reach dynamic balance.
When the water of the humidification chamber 2 is heated and consumed, the water level in the humidification chamber 2 is lower than the lower pipe orifice 92 of the pressure balance pipe 9, the humidification chamber 2 is communicated with the water replenishing chamber 1 through the pressure balance pipe 9, the pressure is equal, and the water in the water replenishing chamber 1 flows into the humidification chamber 2 through the communication hole 5 under the action of gravity to dynamically replenish water in the humidification chamber 2. The above-mentioned cycle is repeated until the water level of the water replenishing chamber 1 is lower than the lower pipe opening 92 of the pressure balance pipe 9.
Example two:
as a further improvement of the first embodiment, the pressure equalization channel 3 further comprises a first communication pipe 31, and the first communication pipe 31 is located outside the humidification chamber 2. One end of the first communicating pipe 31 is communicated with the water replenishing cavity 1 and is positioned at the upper part of the water level surface of the water replenishing cavity 1; the other end of the first communicating pipe 31 is communicated with the humidification chamber 2 and is positioned at the upper part of the water level of the humidification chamber 2.
When the respirator works, the water replenishing chamber 1 and the humidifying chamber 2 are both in a closed state. When the water is supplemented by adopting the intravenous injection mode, the soft infusion bag supplements water into the water supplementing cavity 1 through the intravenous injection port 6. The water of the water replenishing chamber 1 flows to the humidifying chamber 2 through the communication hole 5. If the lower orifice 92 of the pressure balance tube 9 is submerged by water, and the float ball 7 is not fully pressed against the intravenous port 6, the water replenishing chamber 1 will continue to replenish water to the humidification chamber 2. The intravenous injection port 6 is used for supplementing water into the water supplementing chamber 1 all the time, the space volume of the water supplementing chamber 1 is reduced, the air pressure is increased, and water in the water supplementing chamber 1 can continuously enter the humidifying chamber 2 under the action of pressure difference, so that the normal use of the humidifying device is influenced.
The pressure balance channel 3 is provided with a first communicating pipe 31 for communicating the water replenishing chamber 1 and the closed chamber of the humidifying chamber 2. When the pressure between the chambers reaches balance, the water level of the humidifying chamber 2 is always kept level with the water level of the water replenishing chamber 1. When the water level of the water replenishing cavity 1 is over the lower pipe orifice 92, the floating ball 7 is not completely propped against the intravenous injection port 6, the intravenous injection port 6 continues to replenish water into the water replenishing cavity 1, the water level of the water replenishing cavity 1 continues to rise, when the floating ball 7 rises to prop against the intravenous injection port 6, the water level between the water replenishing cavity 1 and the humidifying cavity 2 reaches balance, and the intravenous injection port 6 stops replenishing water. In this embodiment, the first communication pipe 31 is a hose.
Example three:
referring to fig. 4, as another embodiment of the present scheme, the pressure balance channel 3 includes a pressure balance pipe 9, an upper pipe mouth 91 of the pressure balance pipe 9 is communicated with the moisturizing chamber 1, and a lower pipe mouth 92 extends to the bottom of the humidifying chamber 2. The pressure balance pipe 9 is located on the humidification chamber 2, the pressure balance channel 3 further comprises a second communicating pipe 32, the upper pipe orifice 91 is communicated with the humidification chamber 2 through the second communicating pipe 32, and the lower pipe orifice 92 of the pressure balance pipe 9 extends to the water level of the humidification chamber 2 to be level.
Specifically, the top of the humidification chamber 2 is provided with a mounting hole, and the pressure balance tube 9 is mounted on the humidification chamber 2 through the mounting hole. The lower nozzle 92 extends to the water level of the humidification chamber 2 and is level, and the upper nozzle 91 extends out. The upper orifice 91 is communicated with the humidification chamber 2 through the second communication pipe 32. The humidification chamber 2 is provided with a second communication hole which is positioned at the upper part of the water level of the humidification chamber 2. The second communication pipe 32 is connected to the second communication hole.
Compared with the scheme of the second embodiment, the pressure balance pipe 9 is arranged on the interlayer plate and is positioned in the water replenishing chamber 1 and the humidifying chamber 2; the pressure balance pipe 9 and the first communicating pipe 31 are respectively arranged. In the embodiment, the pressure balance pipe 9 is communicated with the second communicating pipe 32, so that the overall structure of the pressure balance channel 3 is simplified, the installation is easy, the arrangement of the installation hole on the interlayer plate is avoided, and the risk of polluting the humidified water body is reduced. In this embodiment, the second communication pipe 32 is a hose.
Referring to fig. 5 and 6, as a further improvement of the above technical solution, the lower nozzle 92 is disposed obliquely, and the lowest point of the lower nozzle 92 is located above the communication hole 5; the highest point of the lower orifice 92 is level with the water level of the humidification chamber 2.
The pressure balancing pipe 9 is used for balancing the pressure between the cavities of the water replenishing chamber 1 and the humidifying chamber 2. When the respiratory support device works, the gas flows through the pipeline of the pressure balance pipe 9. When the water level of the humidification chamber 2 gradually rises and is close to the lower pipe orifice 92, the retention force of water in the pressure balance pipe 9 is too large, so that the pressure balance pipe 9 is blocked by water, and the lower pipe orifice 92 generates bubbles to influence the normal water replenishing function.
Referring to fig. 7, in the present embodiment, the lower nozzle 92 is disposed obliquely at an inclination angle α of 10 ° to 30 °. The highest point of the lower orifice 92 is level with the water level of the humidification chamber 2. When the water level of the humidification chamber 2 gradually rises and is close to the lowest point of the lower pipe orifice 92, the gas in the pressure balance pipe 9 is discharged from the gap between the inclined surface and the water level, so that the water is prevented from being retained in the lower pipe orifice 92 to block the running channel of the pressure balance pipe 9, and the normal water replenishing function in the humidification chamber 2 is maintained.
In the scheme, as a further improvement of the technical scheme, the water replenishing cavity 1 and the humidifying cavity 2 are arranged in a split manner, the water replenishing cavity 1 comprises a water replenishing cavity body 11 and a first box cover 12 covering the water replenishing cavity body 11, and the humidifying cavity 2 comprises a humidifying cavity body 21 and a second box cover 22 covering the humidifying cavity body 21; the water replenishing port 4 for storing and replenishing water and the intravenous injection port 6 for supplementing water by intravenous injection are both arranged on the first box cover 12; the second box cover 22 is provided with a gas inlet 10 for communicating high-pressure gas and a gas outlet 13 for discharging gas.
