The specific embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to a graphic preferred embodiment, can clearly present.By the explanation of the specific embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the present invention, yet appended graphic provide with reference to and explanation usefulness, the present invention is limited.
Before the present invention is described in detail, be noted that in the following description content, similarly element is to represent with identical numbering.
As shown in Figures 1 and 2, it is a preferred embodiment of breathing mask of the present invention, this breathing mask 100 comprises one in order to cover the cover body 1 in patient face, an and appendix 2 that is connected in cover body 1 bottom, appendix 2 can be connected with the respirator (not shown) by a gas delivery tube 3, draws so that the oxygen gas that respirator provides can transfer to the cover body 1 interior patient of confession via gas delivery tube 3 and appendix 2.
Such as Fig. 1, Fig. 2 and shown in Figure 3, appendix 2 comprises one first pipe fitting 21, the first pipe fitting 21 comprises a housing 211, housing 211 is close to the perforation 11 of bottom in order to be arranged in one of cover body 1, preferably, housing 211 is to be the state that interference (interference) cooperates with 11 of perforation, so that housing 211 can not break away from cover body 1 after being arranged in the perforation 11 of cover body 1.Housing 211 comprises a diapire 212, an and surrounding wall 213 that is protruded out up by diapire 212 outsides, diapire 212 has a bottom 214, and surrounding wall 213 has a top 215, and diapire 212 and surrounding wall 213 define a gas room 216 that is positioned at 215 on bottom 214 and top jointly.Because the top 215 of surrounding wall 213 is open shape so that gas room 216 can with cover body 1 internal communication, whereby, institute's Exhaled gasesS can be circulated in the gas room 216 when the patient exhaled.
Such as Fig. 2 and shown in Figure 5, housing 211 also defines one and makes gas room 216 and the outside through hole 210 that is communicated with, and the caregiver selectively is installed in a lid 24 on the housing 211 with sealing through hole 210.When caregiver's wish is measured the gas concentration lwevel value of patient's Exhaled gasesS, can with lid 24 by pulling down on the housing 211, so that measuring device 4 with a carbon dioxide, through hole 210 be connected.Carbon dioxide measures device 4 and comprises that an end is installed on filter 42, a communicating pipe 43 that is connected with filter 42 that through hole 210 interior steering knuckles 41, are installed on steering knuckle 41 other ends, and a gas concentration lwevel measurer 44 that is connected with communicating pipe 43.In the present embodiment, because the gas outlet 222 of the second pipe fitting 22 is adjacent to patient's nose, therefore, the oxygen gas that gas delivery tube 3 is transmitted can be circulated to cover body 1 interior direct nose for the patient by gas flow 223 and draw, and can not impact patient institute Exhaled gasesS.Patient institute Exhaled gasesS can the top 215 inflow gas rooms 216 via surrounding wall 213 in, the gas of part can be expelled to the outside via steam vent 219, and the gas of part can be via adapter coupling 41, filter 42, and transfer to communicating pipe 43 on the gas concentration lwevel measurer 44, wherein, filter 42 can filter dampness and the impurity of patient exhalation air, because the oxygen gas that is circulated in the cover body 1 by gas flow 223 can not impact patient institute Exhaled gasesS, whereby, make gas concentration lwevel measurer 44 can measure exactly the gas concentration lwevel value of patient's Exhaled gasesS.
In addition, because surrounding wall 213 external diameters of the first pipe fitting 21 are larger, so that patient's Exhaled gasesS can be easily via in the 215 inflow gas rooms 216 of top, the carbon dioxide accumulation of avoiding patient's Exhaled gasesS is cover body 1 in and repeated absorption by the patient.
It should be noted that, in design, the diapire 12 of housing 211 also can be established a spliced eye 2120 and plug for the second pipe fitting 22, so that the air inlet 221 of the second pipe fitting 22 can be communicated with connection tube section 217.Moreover appendix 2 also can omit connection tube section 217, and the gas delivery tube 3 by less external diameter is inserted in the air inlet 221 of the second pipe fitting 22, can reach equally oxygen gas is transferred to effect in the second pipe fitting 22.
Conclude above-mentioned, the breathing mask 100 of the present embodiment, housing 211 by the first pipe fitting 21 defines gas room 216, and the contiguous patients' in the gas outlet 222 of the second pipe fitting 22 nose and the second pipe fitting 22 and connection tube section 217 define the design of gas flow 223 jointly, draw so that the oxygen gas that gas delivery tube 3 is transmitted can be circulated to cover body 1 interior direct nose for the patient by gas flow 223, and can not impact patient institute Exhaled gasesS.Patient institute Exhaled gasesS can the top 215 inflow gas rooms 216 via surrounding wall 213 in, portion gas can be expelled to the outside via steam vent 219, portion gas can flow out to carry out the measurement of gas concentration lwevel value through port 210, whereby, make gas concentration lwevel measurer 44 can measure exactly the gas concentration lwevel value of patient's Exhaled gasesS.Moreover, by the design of check valve 23, patient's Exhaled gasesS can be discharged, repeat the gas in the draw gas room 216 when air-breathing with the minimizing patient, really can reach the purpose of institute of the present invention demand.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
