Specific embodiment
Embodiment 1
Words, the "upper" therein such as heretofore described " top ", " top " are with air outlet slit 13 shown in Fig. 2
Direction, that is, top when warmer is normally placed.Words such as " lower sections " refer to the direction opposite with "upper".
Ventilator-structure provided by the invention is as shown in Figure 1, include ventilator 1 and humidifier 2, the gas of ventilator 1
Outlet is connected on the interface 4 of humidifier 2 by connecting tube 3；Inside humidifier 2, it is provided with by hydrophobic hollow fiber pipe
Array 7, the hydrophobic hollow fiber pipe array are by the hydrophobic polymeric hollow fibre pipe of more root surfaces institute arranged in parallel
It constitutes, the micropore that gas can be allowed to pass through, hydrophobic hollow fiber pipe is distributed in the surface of the polymeric hollow fibre pipe
Array 7 is connected to by hose 5 with interface 4；As shown in Fig. 2, being additionally provided with sink 6 inside humidifier 2, the bottom of sink 6 is opened
Mouthful, and the bottom of humidifier is provided with heating plate 12；The top of humidifier 2 is provided with air outlet slit 13.
During use, ventilator 1 is first turned on, the oxygen generated can pass through connecting tube 3, interface 4, hydrophobicity
Hollow fiber conduit array 7 enters to the inside of warmer 2 in turn, due to the polymeric hollow fibre tubing matter of surface hydrophobicity be by
The polymer that air can be allowed to pass through, therefore, air can be discharged by the micropore on its surface, and then pass through 2 top of humidifier
Air outlet slit 13 is discharged, and can connect and uses to patient respiration.
The polymeric hollow fibre pipe of surface hydrophobicity employed in the present invention can be using conventional polymer material
Hollow fiber filter membrane, this filter membrane surface are usually to have micron-sized micropore, such as 50~500 microns, therefore can make to breathe
Air discharge in machine 1, existing many technologies provide the surface-hydrophobicized technology of polymeric filters, such as can be with grafted hydrophobic
Property group achieve the purpose that polymer surface hydrophobic is modified, heretofore described " hydrophobic " can be understood as water droplet in polymer
The contact angle on surface is greater than 120 °, and water droplet is not easy drawout in surface of polymer material, will form drop-wise.
When humidifier 2 is started to work, water can be discharged from the bottom of sink 6, when water is flow on the surface of heating plate 12, meeting
Carburation by evaporation occurs, and then steam is made to flow upward to and then can enter in air outlet slit 13, in the air for generating ventilator
Moisture content improves.
As shown in figure 3, when warmer 2 overturns, since hydrophobic hollow fiber pipe array 7 is using arranged in parallel
Hydrophobic hollow fiber conduit, drop 14 are not easily wetted by its surface, will form drop-wise, therefore are not easy to fall on the hollow fibre of hydrophobicity
Pipe array 7 is tieed up towards that side of air outlet slit 13, also ensures that the water in machine is not easy to flow out and lead to safety problem.
In an other embodiment, as shown in Fig. 2, being also set up in the top of hydrophobic hollow fiber pipe array 7
There is hydrophilic hollow fibre pipe array 8, hydrophilic hollow fibre pipe array 8 is the polymeric hollow fibre hydrophilic by more root surfaces
Manage it is arranged in parallel constituted, the micropore that gas can be allowed to pass through is distributed in the surface of the polymeric hollow fibre pipe, hydrophilic
Property hollow fiber conduit array 8 be connected to by hose 5 with interface 4.
Here the polymeric hollow fibre pipe of surface hydrophilic with above-mentioned hydrophobic hollow fiber conduit be it is similar, can be with
Using conventional hollow fiber filter membrane, this filter membrane surface is usually to have micron-sized micropore, such as 50~500 microns, when exhaling
When suction machine 1 is started to work, air can be also delivered in hydrophilic hollow fibre pipe array 8 by connecting tube 3, and then through porous
It is delivered at air outlet slit 13；Its surface hydrophilic refer to water droplet its polymer surfaces contact angle less than 60 °, that is to say, that water
Drop its surface can promptly wetting and spreading, more disclose makes polymeric filters surface hydrophilic in the prior art
Modification technology, such as the hydrophilic radical in its surface modification, to achieve the purpose that surface hydrophilic modification.
When in use due to humidifier 2, it usually will appear water droplet positioned at top, water droplet can be flow to thin to after flowing down time
The surface of aqueous hollow fiber conduit, and its surface is not easy to be spontaneously wet out by water, and water droplet is easy to cause to be layered on hydrophobic hollow fiber
The surface of pipe does not fall, and the effective surface area of hydrophobic hollow fiber pipe is be easy to cause to reduce；Therefore, by being set again on its surface
Hydrophilic hollow fibre pipe is set, when there is drop to fall, water droplet can make water at it rapidly in hydrophilic polymer unfolded surface
Surface is only very one layer thin, and since polymeric hollow fibre pipe constantly has air to be discharged from micropore, very thin water layer can be very
It is taken away fastly by air, avoids the problem of water droplet stops hydrophobic polymer doughnut surface.
In an other embodiment, such as Fig. 2, hydrophobic hollow fiber pipe array 7 is by sliding bar 9 and sink
It constitutes and is flexibly connected between 6, the top of sliding bar 9 is provided with pressure sensor 10, the draining between sink 6 and heating plate 12
It is additionally provided with solenoid valve 11 at mouthful, when the pressure that pressure sensor 10 detects reaches threshold value, solenoid valve 11 closes discharge outlet
It closes.
When using this structure, after night overturning humidifier 2, drop 14 can be in hydrophobic hollow fiber pipe array
Surface forms water droplet, and since hydrophobic hollow fiber pipe array is slidably connected by sliding bar 9 and 6 outer surface of sink,
Therefore, sliding bar can be slided by gravity to the lower section in Fig. 3, and then press pressure sensor 10, when water droplet amount is more
When, the pressure that pressure sensor 10 can be made to detect is more than threshold value, and then pressure sensor 10 makes solenoid valve 11 work, and makes sink
6 discharge outlet drained outward are closed, and are prevented water further to flow out, are made equipment safety.
