43 being capable of air inlet and outlet.After artificial force, gas is by air inlet port sealed valve from the first internal diameter of first pipe
Place shifts the second inner radius of first pipe onto, and gas enters via the gap between sealed valve and the second internal diameter of first pipe
Inflating catheter 4, and then inflated to cuff 3；At the end of inflation, feeder, effect of the sealed valve in the elastic force of spring are removed
Under, it shifts the first inner radius of first pipe onto from the second inner radius of first pipe, air inlet port is firmly sealed, cuff is prevented
3 gas leakage.
In the present embodiment, when medical staff needs to apply general anaesthetic to patient using tracheal catheter, at this moment generally requiring makes
It is inflated to cuff 3 by the check valve 43 on inflating catheter 4 with feeder.With continuous inflation, the pressure in cuff 3 is continuous
Variation increases, and with the variation of pressure, baroceptor 42 will indicate the pressure size situation in cuff 3.Air pressure sensing
Device 42 for medical staff provide one it is visual, can incude judge inflation whether qualification, foundation up to standard, avoid because of cuff 3
Gas leakage caused by insufficient pressure influences ventilatory effect, in addition occur oral cavity endocrine, backflow in stomach object into air entering flue wind
Danger, the dangerous appearance such as ischaemic, bleeding and necrosis, tracheoesophageal fistula caused by preventing 3 hypertonia of cuff possible.
The gas outlet of inflating catheter 4 in the present embodiment is connected to baroceptor 42, pilot balloon 44, cuff 3 respectively,
Feeder is inflated by check valve 43 to pilot balloon 44 and cuff 3 simultaneously, so that baroceptor 42 and cuff 3 is had identical
Pressure.Because the pressure size in baroceptor 42 is equal with the pressure size in cuff 3, medical staff
Know whether the pressure size in cuff 3 suits the requirements by checking the size of 42 pressure of baroceptor, reaches requirement, overcome
Doctor can only be with feeling and experience judge whether cuff 3 inflates blindness appropriate.
Further, it is provided with signal lamp 425 on baroceptor 42, when the gas being filled with by 43 air outlet of check valve
When body flows through the gas passage 423 inside baroceptor 42, gas pressure detector 424 can incude inside gas passage 423 in real time
Air pressure size, and then the pressure control plate inside baroceptor 42 can control signal lamp 425 and be shown according to air pressure size
The light of different colours.
Signal lamp 425 can show the signal lamp of yellow, green or red in normal use, when signal lamp 425 is shown
For yellow when, show that 3 internal pressure of cuff is not up to standard at this time；When signal lamp 425 is shown in green, show at this time in cuff 3
Portion's pressure is up to standard；When signal lamp 425 is shown in red, show that 3 internal pressure of cuff is exceeded at this time.That is, using
When the multifunctional trachea catheter of the utility model, the color of observation signal lamp 425 is only needed, doctor is it is known that 3 internal pressure of cuff
Whether power complies with standard.When signal lamp 425 is shown in green, illustrate that pressure is up to standard in cuff 3.At this point, in cuff 3
Pressure not only can effective closed airway, but also be not higher than tunica mucosa tracheae capillary perfusion pressure, can also prevent airway mucus ischemic damage
Injure tracheoesophageal fistula, the complication such as tracheostenosis after tube drawing.
Pressure when 3 pressure of cuff is not up to standard is less than 20cmH2O, pressure when 3 pressure of cuff is up to standard are 20cmH2O~
30cmH2O, pressure when 3 pressure of cuff is exceeded are more than 30cmH2O.Pressure is 20cmH in cuff 32O~30cmH2When O, both
The gas leakage between tracheal catheter and tracheal wall can be blocked, and the blood circulation of tracheal mucosa will not be impacted.
When signal lamp 425 is shown as yellow, illustrate that 3 pressure of cuff is less than 20cmH2O needs to continue to inflate to cuff 3；
When signal lamp 425 is shown in green, illustrate 3 pressure of cuff in 20cmH2O~30cmH2Between O, the pressure of cuff 3 is at this time
Suitable, it is inflated without being further continued for；When signal lamp 425 is shown in red, illustrate that 3 pressure of cuff is more than 30cmH2O。
In the present embodiment, preferably, baroceptor 42 can be a diffusion silicon pressure sensor.The diffusion silicon
Pressure sensor be using monocrystalline silicon as matrix, by high-precision IC to signal enhanced processing, compensate again, export control again, use
The silicon-sensitive with resistance bridge and precision mechanics structure has been made in advanced ion implantation technology and miromaching
Element.It is acted on silicon-sensitive element by pressure interface by measuring pressure, realizes pressing force and the linear of output signal turns
It changes, compensates for the temperature performance of sensing element by rear class microprocessor chip and do pressure calibration, can be by LCD or LED
Mode shows actual pressure size.
The inner surface of the tube body 1 of the tracheal catheter of the utility model is provided with reinforced wire (not shown), the reinforced wire
Supporting role is played to tube body 1, strengthens the diametric intensity of tube body 1, keeps the unimpeded of 1 channel of tube body.
Preferably, above-mentioned reinforced wire is arranged along the inner surface spiral of tube body 1, spiral way can play preferably support and make
With.
The tracheal catheter of the utility model further includes Catheter for sputum aspirating 5, Catheter for sputum aspirating 5 and tracheal catheter integrally connected.Suction sputum
The setting of suction sputum mouth 51 of conduit 5 is between cuff 3 and tube body first end 2 are open, as shown in Figure 1.Practice have shown that in anaesthesia process
In, in human airway, on the top of cuff 3, either the seldom product phlegm of secretion or secretion mainly concentrate on tube body to product phlegm
Between 1 first end, 2 opening and cuff 3, therefore position setting as suction sputum mouth 51 is more conducive to point attracted in air flue
Secretion.
The inside and outside perforation of Catheter for sputum aspirating 5, can fully attract the secretion in air flue, when also can avoid usually suction sputum, sputum aspirator tube
The damage to air flue is passed in and out repeatedly.When suction sputum, without disconnecting breathing circuit, the continuity of air flue oxygen supply can guarantee.
It is provided with vacuum aspiration port 53 between the phlegm outlet port 52 and suction sputum mouth 51 of Catheter for sputum aspirating 5, is inhaled by pressing negative pressure
Draw mouth 53 to improve suction sputum effect.Catheter for sputum aspirating 5 further includes capping 54, which includes phlegm outlet port capping and vacuum aspiration port
Capping, phlegm outlet port capping are used for being opened and closed vacuum aspiration port 53 for being opened and closed phlegm outlet port 52, vacuum aspiration port capping.
When needing suction sputum, the capping of the capping and phlegm outlet port 52 of vacuum aspiration port 53 is opened, then to vacuum aspiration port
53 are pressed, and suction sputum is carried out.When not needing suction sputum, the capping of vacuum aspiration port 53 and the capping of phlegm outlet port 52 are covered,
The sanitation and hygiene for keeping Catheter for sputum aspirating 5, prevent from polluting.
Capping 54 can be wholely set with the vacuum aspiration port of Catheter for sputum aspirating 5 53 and phlegm outlet port 52, can also be independent
At lid, this can according to circumstances be determined, be not unique, it will be appreciated by those skilled in the art that and expecting.At this
In utility model, preferably phlegm outlet port capping and vacuum aspiration port capping series connection are wholely set.
Herein, the aperture of Catheter for sputum aspirating 5 is the general standard aperture of medicine, is conducive to directly attract in patient airway
Secretion.
Meanwhile Catheter for sputum aspirating 5 is so that in inhalation anesthesia, can in the case where not turning off breathing circuit suction sputum, can be big
The big air pollution for reducing inhalation anesthetic to operating room, has prodigious protection to medical worker.
The utility model can simply, rapidly be adjusted gasbag pressure in 20cmH by baroceptor 422O~
30cmH2The safe range of O greatly reduces the generation of complication, to keep entire anaesthesia process safer, preferably protects
