The air bag arranged in the trachea cannula is improved and is connected with the connecting tube, an appropriate amount of air is injected into the air bag through the air bag connecting tube for expanding the air bag, and the connecting tube is connected with the pressure sensor, so that the pressure in the air bag can be monitored; and real-time monitoring is performed on comparison of the preset threshold value through the comparator, and an alarm is made automatically when a preset pressure threshold value is reached.
Description
Technical field
This utility model patent belongs to the endotracheal intubation field, relates to the tracheal intubation that a kind of pressure can be monitored.
Background technology
Tracheal intubation is a kind of medical material of commonly using very much clinically, the patient of general anesthesia or epidural anesthesia and the treatment of respiratory failure etc. often need per os or nasal trachea cannula, intubate is at first inserted trachea through the medical worker, then give and inject a certain amount of air in the air bag, make airbag inflation and be stuck in trachea interior with slip-off preventing, at present estimate pressure in the air bag with doctor's experience or feel often, science is not strong, the too small effect that does not reach sealing intubate exterior air drain slit of pressure, pressure is excessive to cause trachea local organization ischemia even necrosis, serious complication occurs.Therefore, if can carry out Real-Time Monitoring to intracapsular pressure, can be more directly perceived, science carry out medical care precess, take precautions against the generation of malpractice, therefore have important clinical meaning and social value.
The utility model content
The tracheal intubation that provides a kind of pressure to monitor is provided the technical problem that this utility model solves, after tracheal intubation is inserted, inject suitable air by the air bag connection tube and make airbag inflation, pressure monitoring and warning system are carried out the pressure Real-Time Monitoring by the air bag connection tube simultaneously, prevent unnecessary malpractice.
This utility model is to be achieved through the following technical solutions:
The tracheal intubation that a kind of pressure can be monitored, comprise tracheal intubation, tracheal intubation is provided with air bag, offer the port that is connected with connection tube on the air bag, one end of connection tube is connected with air bag, and the other end is connected with pressure transducer, and pressure transducer is connected with display, pressure transducer also sends to pressure detecting signal comparator and default threshold ratio, and comparator also is connected with warning emitter.
Described comparator also is connected with pressure regulator.
Described warning emitter comprises voice prompting device and alarm lamp.
Described pressure transducer is differential pressure transducer.
Described connection tube is transparent flexible flexible pipe.
Compared with prior art, the utlity model has following useful technique effect:
The tracheal intubation that the pressure that this utility model provides can be monitored, improve by the air bag to the tracheal intubation setting, air bag is connected with connection tube, inject suitable air by the air bag connection tube and make airbag inflation, be connected with pressure transducer by connection tube, so just can realize the pressure in the tracheal intubation upper gasbag is monitored; And carry out Real-Time Monitoring by comparator and default threshold ratio, when reaching default pressure threshold, automatically give the alarm.
The tracheal intubation that the pressure that this utility model provides can be monitored can also realize size adjustment to threshold value by pressure regulator, realizes the Extraordinary service; Overcome in the past regular discharge, with patient's sensation, with medical personnel's experience, dynamically the defective of Real-Time Monitoring prevents unnecessary malpractice.
Description of drawings
Fig. 1 is the tracheal intubation structural representation;
Fig. 2 is connection diagram of the present utility model.
Wherein, 1 is connection tube, and 2 is tracheal intubation, and 3 is air bag.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in detail, described is to explanation of the present utility model rather than restriction.
Referring to Fig. 1, Fig. 2, the tracheal intubation that a kind of pressure can be monitored, comprise tracheal intubation 2, tracheal intubation 2 is provided with air bag 3, offers the port that is connected with connection tube 1 on the air bag 3, and an end of connection tube 1 is connected with air bag, the other end is connected with pressure transducer, pressure transducer is connected with display, and pressure transducer also sends to pressure detecting signal comparator and default threshold ratio, and comparator also is connected with warning emitter.
After tracheal intubation is placed in patient's trachea, inject the gas of appropriate amount to air bag through connection tube with blowing up a balloon, airbag inflation, thus tracheal intubation is fixed in patient's trachea; This moment, the other end of connection tube was connected with pressure transducer, realized on the one hand the sealing to air bag, can change the pressure in the air bag on the other hand and monitor.
Concrete, comparator also is connected with pressure regulator, realizes the size adjustment to threshold value, realizes the Extraordinary service.
Described warning emitter comprises voice prompting device and alarm lamp, finds hypotony in the air bag or too high after when comparator and threshold ratio, sends signal communication voice prompting device and alarm lamp, in time diagnosis of prompting medical personnel or process; Then do not send alarm signal when not exceeding threshold value.
Described pressure transducer is differential pressure transducer, in order to embody more accurately the variation of the pressure in the air bag.
Described connection tube is transparent flexible flexible pipe, so just can realize the flexible arrangement in the certain limit.
The concrete operations of urethral catheterization system with pressure monitoring function are as follows:
When 1, patient clinical needed tracheal intubation, medical worker's per os or per nasal circulation of qi promoting cannula art were inserted tracheal intubation.
2, tracheal intubation is connected with pressure transducer and warning system, thereby the pressure in the air bag is realized Real-Time Monitoring.
3, inject the gas of appropriate amount through the air bag connection tube, airbag inflation, thus tracheal intubation is fixed in patient's trachea.
4, monitoring system shows the pressure in the air bag in real time, and hypotony or too high when surpassing the preset alarm scope starts warning system (sound and display lamp flicker), and the timely furnishing of prompting medical worker is processed.
When the state of an illness need to be extracted tracheal intubation, at first lay down pressure transducer, discharge the gas in the air bag fully, then can extract tracheal intubation.
