A main body is composed of a tracheal catheter, and a miniature temperature and pressure monitoring device is arranged on the pipe wall at the front end of the tracheal catheter. The miniature temperature and pressure monitoring device is formed by connecting a miniature temperature probe and a miniature pressure probe. The body part of the miniature pressure probe is embedded in the pipe wall of the tracheal catheter, and the head part of the miniature pressure probe is arranged on the inner side of the tracheal catheter. The miniature temperature probe is embedded in the pipe wall of the tracheal catheter, and the head part is arranged on the outer side of the tracheal catheter. A packaging film is covered on the surface of the outer side of the miniature temperature probe. The periphery of the film is connected with the outer side surface of the tracheal catheter.

Description
Technical field:
The present invention relates to medical apparatus and instruments, relate in particular to the medical monitoring device, the particularly sensing device of temperature and pressure in the air flue, concrete is a kind of bronchus internal environment minisize non-invasive pressure and temp monitoring system.
Background technology:
In the prior art, the continuous variation of temperature and pressure has great importance for the accurate assurance of pathophysiological process and the adjustment of respiration parameter in the monitoring air flue.Wherein, the monitoring device of body temperature has had electronic clinical thermometer at present, infrared temperature sensor and liquid crystal temperature instrument are used clinically, electronic clinical thermometer, it is pharyngeal that infrared temperature sensor and liquid crystal temperature instrument are used to measure human nasal, distal esophagus, bladder and rectum, heart, jugular vein, tympanum, the temperature of forehead and skin of neck, usually medical personnel are pharyngeal with human nasal, distal esophagus, bladder and rectum, heart, jugular vein, tympanum, the temperature of forehead and skin of neck is as the representative of central body temperature, but there are many defectives with these position monitoring center temperature, cause additional injury easily.What is more important simultaneously: acute lung injury (is representative with SARS) occur in early days lung in air flue in variation of temperature, and with course of disease dynamic evolution.Thereby variation of temperature is observed significant for the early diagnosis and the course of disease of acute lung injury in the monitoring air flue.But can directly measure partial temperature of air flue and dynamic change thereof without any device for detecting temperature at present.In addition, the monitoring of mechanics of breathing can reflect the elastic characteristic and the flow resistance characteristic of breast lung, the differentiation of observation respiratory system resistance and the diagnosis and the therapeutic effect of pulmonary parenchyma disease there is valuable help, and respiratory mechanics monitor device of the prior art is positioned at respirator, by very long corrugated tubing, endotracheal tube links to each other with the patient, so being the reset pressure in the patient airway, the pressure that monitors do not change, but pressure through recording after the very long pipeline buffering, although eliminate the influence of mechanical dead space through corrective attempts, but still there is very big error with the reset pressure that records in the air flue, thereby had a strong impact on for the accurate judgement of breathing mechanics parameters and the reasonable adjustment of respiration parameter.Monitoring pressure changes and can reduce because water and mucus are blocked the false increase of airway pressure that pipeline causes the chance of minimizing air flue kinking in the air flue; Can be quicker, monitor mechanical ventilation delicately and cause that the ground airway pressure changes; Directly monitor the interior pressure of bronchia, draw the pressure-volume curve (P-V curve) of alveolar in conjunction with flow and capacity, so that adjust the best PEEP value.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because body-temperature monitoring device of the prior art can only measure that human nasal is pharyngeal, the temperature of distal esophagus, bladder and rectum, heart, jugular vein, tympanum, forehead and skin of neck, and all there are many defectives in the temperature of monitoring human nasopharynx part, distal esophagus, bladder and rectum, heart, jugular vein, tympanum, forehead and skin of neck.Concrete, the temperature at esophagus position is subject to keep somewhere the influence of position; Forehead temperature during CPB rapidly cooling and when heating up and jugular vein blood temperature differ bigger; The bladder temperature is difficult to reflect central temperature during oliguria during CPB, especially meaning is littler during the hypogastric region operation; Rectal temperature changes slow than esophagus temperature, aorta temperature between hypothermic phase.Though tympanic temperature can react the hypothalamus temperature, easy damaged auditory meatus in the measuring process is subject to the influence of skin temperature.Simultaneously, skin temperature is except that the control of acceptor center body temperature, and organism metabolism rate, dermal blood flow, hypodermic insulating properties, room temperature, wind speed etc. all can impact it, thereby have influenced thermometric accuracy.Simultaneously, respiratory mechanics monitor device of the prior art is positioned at respirator, link to each other with the patient by very long corrugated tubing, endotracheal tube, so being the reset pressure in the patient airway, the pressure that monitors do not change, but pressure through recording after the buffering of long pipeline very, although eliminate the influence of mechanical dead space through corrective attempts, but still there is very big error with the reset pressure that records in the air flue, thereby had a strong impact on for the accurate judgement of breathing mechanics parameters and the reasonable adjustment of respiration parameter.Intra-airway pressure is measured and can be reduced because water and mucus are blocked the false increase of airway pressure that pipeline causes, reduces the chance of air flue kinking, can be quicker, monitor the airway pressure variation that mechanical ventilation causes delicately; Directly the pressure in the monitoring bronchia draws alveolar pressure-volume curve (P-V curve) in conjunction with flow and capacity, so that adjust the best PEEP value.
