CN2628074Y - Anti-infecting tracheal tube - Google Patents

Abstract

The utility model relates to an anti-infecting tracheal tube, designed in particular against SARS. At present, the operator need to contact the outer aperture of the prior tracheal tube while air is discharged from the outer aperture of the tracheal tube, which results in a high infection rate of the medical staff. In view of the high infection, the novel tracheal tube is designed for fighting against atypical pneumonia and prevents the medical staff from high-rate prevention. The utility model is characterized in that a tube for sputum aspiration is arranged in the inner wall of the tracheal tube; the exposed part of the tube for sputum aspiration is divided into two parts, wherein, one port is connected with the interface of the sound sensor of the host machine while the other port is connected with the entrance of the micro-suction apparatus of the host machine; the spur of the suction apparatus connects with the sterilization device of the external waste gas. For these technical measures, the tracheal tube can judge whether the tracheal tube is successful and control the sputum aspiration automatically and isolate the expiratory air and sputum from the outside so as to prevent the medical staff from infection for engaging in tracheal tube and sputum aspiration. The utility model is not applicable for fighting against atypical pneumonia, but also applicable for preventing and curing other infectious diseases.

Description

Exempt to infect tracheal intubation

Technical field: this utility model relates to a kind of medical intubate

Background technology: at present, employed intubate in the fight against SARS, abnormally dangerous concerning the operator, whether owing to be to have to choke with patient to cough reaction when tracheal intubation, or the personnel selection ear presses close to the tracheal intubation collar extension, by pushing thorax with sudden force, whether can hear that airflow noise is determined the operation success or not in the lung, only this pressure just listens one and coughs, and will make the high concentration poisonous gas in the patient's trachea rush at medical personnel, causes medical personnel's hyperinfection; And inhale the expectorant operation similar process is arranged also, all belong to the directly closely operation of contact, therefore in the clinical practice of anti-sars, it almost is absolutely infected being responsible for intubate and inhaling the expectorant personnel, and this illustrates that existing intubate and sputum aspirator tool can't avoid patient's gas to propagate.

Summary of the invention:

Task of the present utility model is at the problems referred to above; a kind of tracheal intubation of exempting to infect is provided; whether it can successful so as to judging intubate by monitoring endotracheal airflow noise, and patient's gas is propagated in the time of can avoiding intubate simultaneously and inhale expectorant, thereby protects operator's safety.

Technical solution of the present invention is: a kind ofly exempt to infect tracheal intubation, it is characterized in that: on the tail end of intubate body, be provided with joint, the wall of joint is provided with sensor groups and links to each other with microcannula position and sputum detector main frame, and the other end of joint connects outside waste gas and disinfects pipeline.

Aforesaidly exempt to infect tracheal intubation, it is characterized in that: on the inwall of body, wear a sputum aspirator tube, the front opening of sputum aspirator tube is in the tip of body, the tail end exposed parts of sputum aspirator tube is two ports, one of them port is connected with the sound transducer interface of main frame, another port is connected with the inlet of the miniature attraction controller of main frame, attracts the outlet of controller to link to each other with outside exhaust piping by flexible pipe.

Compared with prior art, the utlity model has following advantage:

(1) because sensor groups can be monitored the respiratory murmur in the respiratory tract, can open sputum aspirator automatically in case of necessity, therefore, when carrying out endotracheal intubation, if the front end of intubate enters in the trachea, clear-headed patient can produce to choke surely and cough, do not cough patient by the extruding thorax and have to choke, this process lung interior-heat air communication that will inevitably become is crossed joint, produces pressure and rapid airflow noise simultaneously, if there are not these variations in the intubate, pick off is sent the corresponding signal of telecommunication into main frame and is handled, work as temperature, pressure and sound are considered as the intubate success when variation reaches certain value synchronously, send prompt tone by speaker, the success of declaration intubate.Do not need operation again if having the signal prompt of temperature, pressure and sound variation synchronously then be considered as intubation defeat.If finding sputum or the branch thing that oozes in the intubate influences intubate and can directly siphon away by the sputum aspirator tube that carries in the intubate, do not need other contact to inhale the expectorant operation, like this in the whole operation process, just need not operator's head near patient, so this utility model makes the operator comparatively speaking away from the source of infection.

(2) owing on the outlet of suction pump or joint, be provided with the soft transparent pipe and be connected with outside negative pressure waste gas disinfection unit, so just patient can the be choked gas of expectoration or the poison in air-flow that squeezes out and the sputum siphons away it by means of the negative pressure of outside along pipeline, therefore utilize this utility model intubate and inhale expectorant and leak, thereby purified surrounding with regard to the breath of having stopped patient.Even this moment, the operator was very near from patient, can not cause gas to infect yet.

(3) use this utility model, after tracheal intubation success, main frame is started working, after the respiratory murmur that is transported to main frame by pick off is amplified by main frame, wherein have one the tunnel to spread out of, make the staff must can not hear ventilation and heart beating situation in the patient's trachea near patient through speaker; Another road signal is through the internal analysis device; differentiate according to the features such as Frequency and Amplitude of respiratory murmur whether what of expectorant and amount of expectoration are arranged; thereby decision triggers the work of vacuum extractor interruption; both having the utlity model has automatic supervision of situations such as respirator working condition, lung internal respiration sound, heartbeat and suction expectorant function, also is the second protection device of respirator.

Description of drawings: Fig. 1 is a structural representation of the present utility model.

The specific embodiment: as shown in the figure, this utility model provides exempts to infect tracheal intubation, it is characterized in that: on the tail end of intubate body 1, be provided with joint 2, the wall of joint 2 is provided with sensor groups 8 and links to each other with microcannula position and sputum detector main frame 6, and the other end of joint connects outside waste gas and disinfects pipeline.The sensor groups here can be monitored intratracheal pressure, temperature and sound, can monitor respiratory murmur, monitoring respirator working condition, the interior sputum of lung and heartbeat situation in the respiratory tract.Implement this utility model, and then can also on the inwall of body 1, wear a sputum aspirator tube 3, the front opening of sputum aspirator tube 3 is in the tip of body 1, the tail end exposed parts of sputum aspirator tube 3 is two ports, one of them port is connected with the sound transducer interface 5 of main frame 6, another port is connected with the inlet 4 of the miniature attraction controller 7 of main frame 6, attracts the outlet of controller 7 to link to each other with outside exhaust piping by flexible pipe.Above-mentioned two kinds of schemes can assist to monitor the airflow noise relevant with the intubate position when tracheal intubation, respiratory murmur in the management after intubate in the monitoring tube and rale sound trigger sputum aspirator work.Difference is that the former can only monitor sound in the trachea, and the latter then not only can monitor the respiratory murmur and the hear sounds in trachea deep, and can start sputum aspirator suction expectorant as required.

This utility model is the desirable intubate of the fight against SARS.
