Abstract

The utility model discloses an optical fiber positioning does not have wound endotracheal tube, include by pipe external tapping, pipe shaft, suit the anterior low pressure gasbag of pipe shaft and with the pipe body of the gasbag gas injection device constitution that low pressure gasbag inner chamber is linked together, the tip of pipe shaft is the toper structure of top circular arc transition at least one gas outlet has been seted up to the tip lateral wall. Lieing in be provided with guide optic fibre and location optic fibre side by side along the pipe shaft axial in the pipe wall of pipe shaft upper wall, the cold light source interface of guide optic fibre and location optic fibre all extends pipe body outside from pipe shaft rear end upper wall position, the luminous end position in top of guide optic fibre in tip position department, the location optic fibre luminous end position in low pressure gasbag rear portion position department. The utility model has the advantage of simple structure, easy mass production, cost low cost, cross infection is avoided to disposable application of being convenient for.

Description

Fiber orientation noinvasive endotracheal tube

Technical field

This utility model relates to medical instruments field, especially relates to a kind of fiber orientation noinvasive endotracheal tube.

Background technology

Set up artificial airway at subject extensive use endotracheal intubation insertion endotracheal tubes such as clinical anesthesia, emergency resuscitation, serious symptom treatments and carry out manually (machinery) ventilation support breathing.The endotracheal tube not only tip used clinically at present is pointed, it is easy to damage trachea；Not possessing guidance tracheal intubation operation and positioning function simultaneously, may result in for tracheal intubation and be strayed into esophagus, conduit inserted the complication such as deep or excessively shallow, tissue injury, when being particularly useful for difficult airway blind tracheal intubation, the complication rate such as tissue injury is higher.

Summary of the invention

This utility model purpose is in that to provide a kind of accurate positioning, operate noninvasive fiber orientation noinvasive endotracheal tube.

For achieving the above object, this utility model can take following technical proposals:

Fiber orientation noinvasive endotracheal tube described in the utility model, including by conduit external tapping, pipe shaft, be sleeved on the anterior low pressure air bag of pipe shaft and catheter body that the air bag gas injection device with described low pressure air bag intracavity inter-connection is constituted；The tip of described pipe shaft is the pyramidal structure of top arc transition, offers at least one gas outlet at described tip sidewall.

Axially being arranged side by side guiding optical fiber and location optical fiber at the tube wall being positioned at described pipe shaft upper wall along pipe shaft, the cold light source interface of described guiding optical fiber and location optical fiber all extends outside catheter body from upper wall position, pipe shaft rear end；The top light emitting end of described guiding optical fiber is positioned at described tip position, and the luminous end of described location optical fiber is positioned at described low pressure air bag rear positions place.

Two gas outlets are offered in described tip sidewall opposite end.

Auxiliary gas outlet is offered at described tip top.

This utility model advantage is in that simple in construction, it is easy to produce in enormous quantities；Cost is cheap, it is simple to cross infection is avoided in disposable application.Tip is set to the pyramidal structure of top arc transition, and gas outlet is opened in tip two side, make its high resilience and comply with glottis anatomical structure, channeled tube core bending 90 degree is moulded " L " type, tip is inserted (cunning) more easily by glottis and is entered trachea, the tip smooth when implementing tracheal intubation operation can avoid tracheal intubation to operate the tissue injury brought, it is to avoid the complication such as laryngeal edema；Guiding optical fiber and location optical fiber are set simultaneously in the tube wall of pipe shaft upper wall, according to the extraneous cold light source that different brightness demand selection brightness is different, being organized in body surface before light transmission trachea and produce two red hot spots (guiding hot spot, location spot) located on a straight line, guidance tracheal intubation operates, determines tracheal catheter position and the endotracheal tube endotracheal degree of depth of insertion, judges whether low pressure air bag is entirely through infraglottic cavity and enters trachea.Overcome the endotracheal tube being widely used at present to operate, can not be accurately positioned, the shortcomings such as bottleneck throat illumination, most advanced and sophisticated easy damaged tissue can not be assisted by guidance tracheal intubation, tracheal intubation operation (especially difficult tracheal intubation) is made to become simple easy, improve tracheal intubation success rate and avoid complication, improving patient and give treatment to success rate, reduce patient medical misery and financial burden；Cold light source can be shared with other medical endoscopes simultaneously, save medical resources, can mini mobile high light cold light source easy to use, before being easy to institute, in way, emergency cannula, battlefield first aid intubate and without grass-roots unit's tracheal intubation of assisted gas cannula apparatus and equipment, it is widely used in the subjects such as clinical anesthesia, emergency resuscitation, serious symptom treatment and needs Patients Underwent Endotracheal Intubation, be particularly suited for difficult airway blind tracheal intubation.Indication: per os (nose) tracheal intubation under normal air flue photopic vision；Lower per os (nose) tracheal intubation of difficult airway visible laryngoscope auxiliary；Difficult airway per os (nose) blind tracheal intubation；It is particularly suited for Zhang Yuqin tube core guidance method per os blind tracheal intubation art and Zhang Yuqin rotating techniques per nasal blind tracheal intubation art.
