Detailed Description
The technical solution of the present invention is further illustrated by the following specific examples.
Example one
The medical nasal oxygen tube with the function of auxiliary monitoring of the respiratory frequency comprises an oxygen tube 1, a nasal obstruction 2 and a sampler 3, wherein the oxygen tube 1 is communicated with the nasal obstruction 2, and a sampling port 4 of the sampler 3 is arranged on the inner side of the nasal obstruction 2.
The sampling port 4 is arranged at the same level with the nasal obstruction oxygen outlet 5.
The sampling port 4 is positioned at the geometric center of the nasal obstruction oxygen outlet 5.
The nasal plug 2 is a spherical nasal plug.
The sampler 3 is arranged on the side wall of the nasal obstruction 2.
The sampler 3 adopts a sampling pipe.
The sampling port 4 is connected with the inner wall of the nasal plug 2 through a limiting frame 6.
The limiting frame 6 comprises a fixing ring 7 and a supporting rib 8, the fixing ring 7 is fixedly connected with the sampling port 4, the supporting rib 8 is arranged on the fixing ring 7, and the supporting rib 8 is connected with the inner wall of the nasal plug 2.
The support ribs 8 are arranged in an annular array on the outer wall of the fixing ring 7.
The number of the support ribs 8 is 3.
The operating principle of the scheme is as follows, the far end of the oxygen tube 1 is connected with the oxygen therapy device, oxygen is conveyed to the nasal obstruction 2 by the oxygen tube 1 for oxygen supply, the far end of the sampler 3 is connected with the end-tidal carbon dioxide detector, and the sampling port 4 acquires carbon dioxide exhaled by a patient to obtain continuous and effective end-tidal carbon dioxide partial pressure waveform. The method is used for accurately measuring the respiratory frequency, knowing the inspiratory-expiratory ratio and finding out the shortness of breath, expiration delay or pause in time.
The dynamic PetCO2 waveform can initially reflect whether a patient can effectively eliminate carbon dioxide from the body:
the ideal PetCO2 waveform should keep an effective plateau period to ensure an effective breathing and ventilation function;
PetCO2 is abnormally reduced in value, which reflects that the exhalation is not smooth or the respiration amplitude is reduced, so that the carbon dioxide in the body can not be fully discharged, and the adverse conditions such as over sedation, hypopnea or tongue root tenesmus of the patient are related and should be corrected in time.
Furthermore, in order to achieve the best effect of the sampling port 4, the sampling port 4 is arranged at the same level with the position of the nasal obstruction oxygen outlet 5, and the sampling port 4 is positioned at the geometric center of the nasal obstruction oxygen outlet. And a limiting frame 6 is arranged at the position of the stable sampling port 4 for supporting and limiting. The limiting frame 6 is composed of a fixing ring 7 and supporting ribs 8, the fixing ring 7 is used for fixing the position of the sampling port 4 to enable the sampling port to be limited, and the supporting ribs 8 are used for limiting the fixing ring 7 and simultaneously play a role in supporting the nasal obstruction oxygen outlet 5 to enable the nasal obstruction oxygen outlet to be prevented from being extruded to cause the PetCO2 waveform to be short or disappear.
Further, to avoid affecting the oxygen flow, the sampler 3 is disposed on the side wall of the nasal plug 2. In actual use, a passage can be arranged on the wall of the nasal plug 2, so that the structure is reasonably optimized, and the nasal plug can be used more conveniently.
Preferably, in the practical production and use, in order to ensure that the regular end-expiratory carbon dioxide waveform can be effectively collected, a gap is left between the nasal plug and the nasal cavity of the patient, so that the smoothness of expiration is ensured, and the complete blockage of the nasal cavity on one side is avoided. Therefore, the nasal plug with at least two specifications is required to be equipped in use. The nasal cavity of the male is wide, the original type nasal plug is preferred, the nasal cavity of the female is thin, and the small type nasal plug is preferred.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the utility model. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
