Description
Technical field
The present invention relates to a kind of medicine equipment, and in particular to a kind of directly monitoring infant's partial pressure of carbon dioxide in endexpiratory gas
Tracheal catheter.
Background technology
End-expiratory carbon dioxide（PETCO2）As a kind of monitoring index, have been considered to except body temperature, breathing, pulse,
The 6th basic vital signs, PETCO beyond blood pressure, arterial oxygen saturation2Fundamental surveillance index during for anesthesia it
One.The application of partial pressure of carbon dioxide in endexpiratory gas monitoring technology allows the clinician to continuously, non-invasively monitor the ventilation of patient
The exchange situation of function and carbon dioxide so that acid-base balance, soda lime failure, excessive too small, the lung ventilator machine of throughput in art
Situations such as tool failure, patient's shock, cardiac arrest, pulmonary embolism and tracheal catheter are strayed into oesophagus can find and adjust in time,
Substantially increase the objectivity and security of patients with general anesthesia operative management.
Existing sampling apparatus is, in tracheal catheter sample near-end, to connect capnometer.However, because tracheae is led
Pipe is relatively thick, inevitably there is one section of fresh gas flow in pipe, to end-expiratory carbon dioxide monitoring for adult
Result influence it is smaller, but for infant patient, because its tidal volume is small, the carbon dioxide diluting effect of fresh gas flow is bright
It is aobvious, using existing sampling apparatus monitoring can be caused inaccurate.Therefore for infant, clinical anesthesia doctor usually abandons monitoring
End-expiratory carbon dioxide, this gives infant respiratory nursing band many hidden danger, unexpected emergency situations can not be found and solved in time.
Clinically lack the tracheal catheter that efficiently sampling can be achieved and infant's end-expiratory carbon dioxide is monitored at present.
The content of the invention
In order to solve the above-mentioned technical problem, infant's partial pressure of carbon dioxide in endexpiratory gas is directly monitored the invention provides a kind of
Tracheal catheter.
Technical solution of the present invention is as follows：
A kind of tracheal catheter for directly monitoring infant's partial pressure of carbon dioxide in endexpiratory gas, including conduit, cuff, joint, the set
Capsule is connected to tube at one end, and the joint is arranged on the other end of conduit, in addition to opening and tubule, and the opening is arranged on set
On conduit between capsule and joint at nearly cuff, opening connection tubule, the tubule end connection End-tidal carbon dioxide monitoring
Instrument.
Further, the capillary inside diameter 0.5-1.2mm.
Further, the capillary inside diameter 1mm.
Further, the opening is away from cuff 1-2cm.
Further, the opening is away from cuff 1cm.
Further, the tubule is connected to catheter wall to the burble point of conduit and separated with conduit.
Further, the burble point is away from joint 2-3cm.
Further, the burble point is away from joint 2cm.
Further, the tubule end sets screw socket, and the tubule passes through screw socket and End-tidal carbon dioxide detector
Connection.
Further, the joint is connected with lung ventilator.
Beneficial effect of the present invention is：
Sampling sites are that opening 1 is arranged on nearly tracheae top, can be by the carbon dioxide in infant patient's air flue through tubule 2
Feeding end-expiratory carbon dioxide monitoring instrument is monitored, and the internal diameter of tubule 2 is thinner, and wherein amount of fresh air is small, and breathing gas is by new
Fresh airflow influence is small, can improve monitoring precision.The present invention is simple in construction, can reflect the last titanium dioxide of patient expiration exactly in good time
Carbon level, using effect is notable.
