Abstract
The utility model provides an air and oxygen mixer. The clean mixed oxygen can be provided to a new-born baby to prevent the harmful consequences of brain injury and inward vision caused by pure oxygen inhalation, and the safety is high. The utility model comprises an outer casing. The utility model is characterized in that a gas channel, a fan and a controller are arranged in the outer casing, the gas channel comprises an air channel and an oxygen channel, the air channel and the oxygen channel are collected, and then connected and communicated with a mixed gas channel, the fan is arranged at the inlet opening of the air channel, a filter structure is arranged between the air outlet opening of the fan and the inlet opening of the air channel, the air suction opening of the fan, the inlet opening of the oxygen channel, and the outlet opening of the mixed gas channel are respectively arranged in the casing body, and the fan is electrically connected with the controller.
Description
(1) technical field
This utility model relates to medical device industry neonate inhalation device parts, is specially air, oxygen mixer.
(2) background technology
At present, China hospital normally is placed in 100% oxygen mask for premature infant's treatment way, and for it provides pure oxygen, Cun Huo probability is bigger like this.But premature infant for those pulmonary's developmental immaturities, can be incompatible after entering air ambient from 100% pure oxygen environment, oxygen content is 21% in the air, the blood supply amount will increase, baby's brain blood flow also will increase, easily like this cause that brain is inner and eye retina is hemorrhage, cause brain injury and lose one's sight.Therefore, 100% oxygen mask oxygen supply has potential hazardness concerning the premature infant of pulmonary's developmental immaturity.
(3) summary of the invention
At the problems referred to above, this utility model provides a kind of air, oxygen mixer, and it can be for neonate provide clean mixing oxygen, prevents that neonate from inhaling brain injury that pure oxygen may cause and adverse consequences such as blind, and safety is higher.
Its technical scheme is such: it comprises shell, it is characterized in that: be provided with gas passage in the described shell, blower fan, controller, described gas passage comprises air duct, oxygen channel, described air duct, oxygen channel gathers the back and is connected with mixed-gas channel and communicates, described blower fan is arranged at the porch of described air duct, be provided with filtration between the air outlet of described blower fan and the porch of described air duct, the inlet scoop of described blower fan, the inlet of oxygen channel, the mixed-gas channel outlet is arranged at shell respectively, and described blower fan and described controller electricly connect.
It is further characterized in that: described filtration comprises filter, and described filter is placed in drawer, and described drawer is plugged between the porch of the air outlet of described blower fan and described air duct; Described mixed-gas channel outlet has two; Described two mixed-gas channels outlet is arranged at the sidepiece and the bottom of described shell respectively; Described mixed-gas channel outlet is provided with guide valve, and described guide valve is installed on described shell, and the Way out of described guide valve is vertical with the Way out of mixed-gas channel.
This utility model is applied in the neonate apparatus of oxygen supply, control the mist oxygen concentration of output by the flow of adjusting oxygen, can in time adjust oxygen supply concentration according to neonatal health status like this, make neonate progressively adapt to external environment, brain injury and blind probability appear in minimizing, and safety is higher.
(4) description of drawings
The constitutional diagram that Fig. 1 decomposes for this utility model;
Fig. 2 is the structural representation of guide valve among Fig. 1.
(5) specific embodiment
See Fig. 1, Fig. 2, this utility model comprises shell, is provided with gas passage, blower fan 6, controller 7 in the shell, and gas passage comprises air duct 5, oxygen channel 14, and air duct 5, oxygen channel 14 gather the back and be connected with mixed-gas channel 10 and communicate; Blower fan 6 is arranged at the porch of air duct 5, be provided with filtration between the porch of the air outlet of blower fan 6 and air duct 5, filtration comprises filter, filter is arranged in the drawer 11, do not express filter among Fig. 1, drawer 11 is plugged between the porch of the air outlet of blower fan 6 and air duct 5, the inlet scoop 13 of blower fan 6, the inlet of oxygen channel 14, mixed-gas channel 10 outlets are arranged at shell respectively, the outlet of mixed-gas channel 10 has two, be arranged at sidepiece (being left side 3 among Fig. 1) and bottom (being the lower cover 2 of shell) of shell respectively, control the flow direction of mixing air for convenience, mixed-gas channel 10 outlets are provided with guide valve 8, guide valve 8 is installed on shell, the vertical (see figure 2) of Way out of the Way out of guide valve 8 and mixed-gas channel 10.Blower fan 6 electricly connects with controller 7.1 is the loam cake of shell, and 4 is the right side of shell, and 9 is packing ring, and 12 is the connecting line of battery, 15 blower fans.Inlet with oxygen during use is connected with oxygen source, guide valve 8 directly stretches to baby's cover, control the throughput that of oxygen source, blower fan 6 produced resistance when oxygen entered into oxygen channel by inlet, rotating speed according to resistance size controller 7 control blower fans 6, thereby adjust the influx of air, and then guarantee the flow and the oxygen content of control mist.Because guide valve 8 directly stretches to baby's cover, the Way out of guide valve 8 is vertical with the Way out of mixed-gas channel, and mixing air enters and directly blows to the cover wall after the baby covers like this, covers wall to dirty along the baby then, can prevent from so directly to blow to the baby, cause baby's discomfort.
