The front end of the reverse injection tube cavity is provided with a filling blocking body, and a reverse air flow outlet communicated with the forward injection tube cavity is arranged on the reverse injection tube cavity behind the filling blocking body. The ventilation pipe has good ventilation effect, does not damage the trachea of a patient, and is convenient and easy to operate.
Description
Technical field
This utility model relates to the medical assistance apparatus that passes through patient's trachea oxygen supply clinically, refers to a kind of two-way high frequency jet ventilation pipe particularly.
Background technology
At present, the high frequency jet ventilation pipe that Anesthesia Department of hospital, Respiratory Medicine and each section serious symptom ward are used for patient's oxygen supply structurally is unidirectional mostly, the problem of ubiquity carbon dioxide accumulation in patient's lung, and ventilatory effect is relatively poor.In order to address the above problem, some medical matters scientific research personnel is fixed on common trachea outer wall with plastic conduit, and turn back 180 ° in the front end of common trachea, to be used for the contra-injection ventilation, though this structure helps the discharge of carbon dioxide in patient's lung, but can in air flue, produce negative pressure during its contra-injection, cause tracheole and alveolar to wither easily, reduce patient's functional residual capacity.And plastic conduit is attached to common trachea outside, is easy to damage upper respiratory tract in the postanesthetic intubate process of patient.This type of breather needs just can use after the common trachea repacking simultaneously, and it makes the loaded down with trivial details complexity of assembling, and service life is short partially, is unfavorable for popularizing in an all-round way using.Also some medical matters scientific research personnel will be fixed on plastic conduit on the common trachea outer wall, front end place in common trachea is bent into the semicircular canal tube head, and the semicircular canal tube head is penetrated in the front end side opening of common trachea, and the opening of semicircular canal tube head is outside common trachea, though can alleviate the reverse negative pressure that in air flue, produces when jet like this, but it still exists easy damage patient upper respiratory tract, defective such as needs just can to use after the repacking.
Summary of the invention
The purpose of this utility model will overcome above-mentioned existing in prior technology defective exactly, develop a kind of ventilatory effect good, do not damage patient's trachea, easy to operately be easy to two-way high frequency jet ventilation pipe.
For realizing this purpose, the two-way high frequency jet ventilation pipe that this utility model is designed has a ventilation body, and the anterior outside of ventilation body is enclosed with inflatable cuff, and the sleeve bag gas-filling pipe is inserted in the inflatable cuff.Be separated into three independently tube chambers by vertical barrier film in the described ventilation body, wherein: being positioned at intermediary tube chamber is that forward sprays tube chamber, is used for forward and sprays the oxygen supply to the patient; Being positioned at a lateral tube chamber is the contra-injection tube chamber, is used for contra-injection drain carbon dioxide; The tube chamber that is positioned at the another side is used to measure the endotracheal secretions of intra-airway pressure or sucking-off for inhaling expectorant or pressure measurement tube chamber.The front end of described contra-injection tube chamber is provided with the filling blockage body, and the contra-injection tube chamber of described filling blockage body back is provided with described forward and sprays the back draught outlet that tube chamber is communicated with.
This utility model is offered a contra-injection tube chamber on the basis of existing unidirectional high frequency jet ventilation body, airflow direction when this contra-injection tube chamber is jet moves to human external from the human lung, She Ji advantage is like this: air-flow forms the Wen Qiuli effect in the contra-injection tube chamber, can take out of the carbon dioxide in the human body lung external at an easy rate, after zoopery and clinical practice, measure patient's arterial blood gas values, proved that its ventilatory effect is good.And this contra-injection tube chamber and suction expectorant or pressure measurement tube chamber all directly design in ventilation body inside, and be easy to operate easy in the tracheal intubation process, can not damage patient's trachea.Simultaneously, this breather is integrated multiple function, is suitable for all patients and uses, and overcome originally to be the trouble of whenever assembling the contra-injection plastic conduit separately for the patient, but large-scale promotion is used.

The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail:
Two-way high frequency jet ventilation pipe shown in the figure has a ventilation body 8, and the front end of ventilation body 8 is the wedge type, so that accurately fast unhinderedly be inserted in patient's the trachea.The anterior outer fix of ventilation body 8 is enclosed with an inflatable cuff 7, and inflatable cuff 7 links to each other with a sleeve bag gas-filling pipe 6, and sleeve bag gas-filling pipe 6 extands rearward to the afterbody of ventilation body 8.Be separated into three independently tube chambers by vertical barrier film in the ventilation body 8, wherein: being positioned at intermediary tube chamber is that forward sprays tube chamber 2, and being positioned at a lateral tube chamber is contra-injection tube chamber 3, and the tube chamber that is positioned at the another side is for inhaling expectorant or pressure measurement tube chamber 1.The front end of contra-injection tube chamber 3 is provided with fills blockage body 5, and the contra-injection tube chamber 3 of filling blockage body 5 back is provided with forward and sprays the back draught outlet 4 that tube chamber 2 is communicated with.Also be connected with suction expectorant or pressure measurement prolongation pipe 11 at the afterbody of inhaling expectorant or pressure measurement tube chamber 1, afterbody at contra-injection tube chamber 3 also is connected with contra-injection prolongation pipe 33, can be in actual mechanical process the length of each tube chamber of flexible so that be connected with corresponding therapeutic equipments fast.Ventilation body 8 and filling blockage body 5 all adopt silastic material to make, and so not only its pliability is good, can not injure patient's trachea, and durable in use, and working life can significantly prolong.
When this utility model used, the front end of the body 8 of at first will ventilating was inserted into the position of about 3～4cm under the patient's trachea glottis, injected air in certain amount from sleeve bag gas-filling pipe 6 tail ends, made inflatable cuff 7 expansions, airtight firmly trachea.Two puff prots by the high frequency jet ventilation machine spray tube chamber 2 and contra-injection tube chamber 3 jet gas towards forward respectively in the different periods then.Spray tube chamber 2 to patient pulmonary injection of oxygen through forward when air-breathing, keep patient's oxygenate.Eject oxygen or air by contra-injection tube chamber 3 during expiration,, flow into forward and spray in the tube chamber 2 through back draught outlet 4.At this moment, the air-flow regurgitated nature separated into two parts, sub-fraction is regurgitated gas and can be sprayed tube chamber 2 through forward and flow to pulmonary, produces certain pressure and makes when exhaling alveolar be unlikely to sunken fully to close, and IA carbon dioxide is easy to outside discharging; And major part is regurgitated gas and can be sprayed tube chamber 2 through forward and outwards flow, thereby can promote the carbon dioxide in the lung to excrete effectively, realizes effectively ventilation.In venting process, can inhale the concentration of expectorant or monitoring expiration unreacted carbon dioxide by inhaling expectorant or pressure measurement tube chamber 1, and not influence normal venting process.
