Abstract
The invention relates to a multifunctional air flow sensor. A body of the air flow sensor is composed of a semispherical air flow sensing air bag 1 and a connector 4. The side of the air flow sensing air bag is provided with two triangular valves 2, 3. The air bag and the valves can sense air flow and move and swing along with breathing air flow. Air flow or sputum is ejected out from the two valves by changing directions on the top of the air flow sensing air bag. The connector can be directly arranged on a connector of a tracheal catheter in a sleeved mode. After an opening of the air flow sensing air bag deviates from an operator, a core of the tracheal catheter is inserted into the tracheal catheter through the opening of the air flow sensing air bag. After the depth and the radian of the catheter core are adjusted, the catheter is inserted with assistance of a laryngoscope. The distance between the front end of the catheter and the glottis and whether the front end of the catheter exists in the trachea or not can be judged according to the movement amplitude of the air flow sensing air bag and the valves. The tracheal catheter without the catheter core can be used for performing leading and judging of catheter insertion through the nose trachea and also can be used for judging whether a patient whose trachea is inserted with the catheter has autonomous respiration or not and observing the status of autonomous respiration and the respiration frequency. The tracheal catheter has the functions of leading directions of ejected bucking articles and the like.
Description
Technical field
The present invention relates to a kind of multifunctional air current induction apparatus.
Background technology
Accurately the correctness of judgement tracheal catheter position is the important step of row endotracheal intubation.Conventional way is after tracheal intubation, to press thorax transtracheal catheters end perception air-flow, or connects simple and easy breathing bag and push the fluctuating that breathing bag is seen thorax, or observes and identify that air bag recovers situation about expanding; The connect end-expiratory carbon dioxide monitoring instrument that condition is good is watched patient's end-expiratory carbon dioxide situation, or directly by fiberoptic bronchoscopy etc.But, expensive can not the popularizing such as end-expiratory carbon dioxide monitoring instrument, branchofiberoscope, and can not be at any time for the field first aid of out operating-room.While identifying by extruding breathing bag method, as endotracheal tube inserts in esophagus gas, be squeezed into gastric, causing that gastric is pressed increases, and can cause reflux erroneous aspiration.Design that other tracheal intubation appurtenances have is complicated, have can not be separately for the long-term observation of autonomous respiration etc.
Summary of the invention
The object of the invention is to: design a kind of multifunctional air current induction apparatus, while both can be used for various anesthesia and first aid, as the position of per nasal or oral trachea cannula guiding and judgement endotracheal tube, used, can be used for again judging that intubation has no spontaneous breathing and autonomous respiration is strong and weak, the observation of respiratory frequency, also can preventing chokes coughs thing and sprays to operator by endotracheal tube, plays guiding and chokes and cough the effect that thing sprays to.
Specific implementation of the present invention is: main body consists of a hemispherical airflow sensor air bag and a joint.Hemispherical airflow sensor air bag is made by thin matter, pliable and tough latex or plastics, and Gao2cm，Qi lower end is closely connected with joint, near joint, has one of long 1.5cm to walk crosswise opening.Slightly biased horizontal opening perpendicular bisector one side has the perpendicular otch of a long 1cm.Two openings form the opening being comprised of small one and large one two triangle flap valve.When respiratory air flow is strong, airflow sensor air bag 1 and triangle flap valve 2,3 all move and swing with respiratory movement.When respiratory air flow is weak, only have flap valve 2,3 to swing by a small margin; Air-flow or sputum change direction and spray from two flap valves at airflow sensor Qi Nang top, thereby reach guiding, change air-flow and choke and cough thing emission direction, reach the object of protection operator and other staff or article.Joint is one to be about in the 1:40 international standard of 2cm taper joint or to be the special fit of other shapes, can directly be enclosed within on the joint of endotracheal tube.
Accompanying drawing explanation
Accompanying drawing is multifunctional air current induction apparatus direct-view figure, wherein 1-airflow sensor air bag, 2-valvelet, 3-large flap valve, 4-joint.
The specific embodiment
Get one of the endotracheal tube of suitable types, the joint 4 of multifunctional air current induction apparatus is enclosed within on the joint of this endotracheal tube, and adjust its direction, the opening of airflow sensor air bag 1 departs from operator, prevents from making sputum spray to operator by endotracheal tube because patient chokes to cough.Then proceed following operation:
When retaining patient's autonomous respiration oral trachea cannula, the opening that tracheal cannula core is passed through to airflow sensor device inserts endotracheal tube, adjust after the degree of depth and radian, under laryngoscope auxiliary, insert endotracheal tube, note observing airflow sensor air bag 1 and flap valve 2, 3 movable amplitude, when movable amplitude is maximum, illustrate that endotracheal tube is over against patient's glottis, at airflow sensor air bag 1 and flap valve 2, 3 insert endotracheal tube while being just inhaled into, extract tube core, adjust after the endotracheal tube degree of depth, airflow sensor air bag 1 and flap valve 2, 3 movable amplitude increases or when constant, illustrate that endotracheal tube is in trachea, remove multifunctional air current induction apparatus, remaining routine operation.While die-offing to nothing activity as the movable amplitude of airflow sensor air bag 1 and flap valve 2,3, illustrate that endotracheal tube slips in esophagus, should operate again.
When first-aid trachea intubate, without stopping closed cardiac massage, the artificial airflow that closed cardiac massage produces is as the air-flow of autonomous respiration generation, so operation is the same with retaining autonomous respiration oral trachea cannula.
When retaining autonomous respiration nasal trachea cannula, connect multifunctional air current induction apparatus, remaining routine operation, observational technique is with retaining autonomous respiration oral trachea cannula.
When the autonomous respiration of observing intubation, connect multifunctional air current induction apparatus, observe airflow sensor air bag 1 and flap valve, 3 movable amplitude: when airflow sensor air bag 1 and flap valve 2,3 are when movable, this patient's no spontaneous breathing is described; When airflow sensor air bag 1 and flap valve 2,3 movable amplitude hour, illustrate that this patient has faint autonomous respiration; When airflow sensor air bag 1 and flap valve 2,3 movable amplitude are when larger, illustrate that this patient has good autonomous respiration, and the frequency of airflow sensor air bag 1 and flap valve 2,3 activities is patient's respiratory frequency.
When doing oral cavity and other nursing for intubation, multifunctional air current induction apparatus joint 4 is enclosed within on endotracheal tube, the choking of bootable patient coughed thing and sprayed to a direction, reaches and prevents that medical personnel and other aseptic or clear areas from suffering being infected with of sputum.
This multifunctional air current induction apparatus be a kind of can be accurately, reliably, guidance tracheal intubation efficiently, observe and decide patient's autonomous respiration intuitively again, can also prevent chokes coughs thing and directly sprays, and reaches the gadget of protection object.Have simple to operate, observe directly perceived, design feature light and handy, with low cost, that result of use is good.
