Description

A kind of bidirectional measurement trachea cannula

Technical field

The utility model relates to the field of medical instrument technology, specifically, being a kind of bidirectional measurement trachea cannula.

Background technique

Currently, clinical each lesion, emergency rescue room, intensive care unit, there are the patients of a large amount of trachea cannulas for operating room.Often After rule intubation, medical worker tentatively judges catheter position in gas according to Gender, age by the scale on trachea cannula The depth in road.However, each patient is independent individual, conventional diagnosis and treatment method or experience cannot adapt to each completely The demand of independent individual.The collocation of different sexes and the bodily form, in conjunction with the difference of the ratio of trunk and lower limb, the moment challenges routine side Method judges the reasonability of catheterization depth.With the progress and development of medical level, the awakening and raising of public science popularization consciousness, The extension of the average life span.Elderly patient, complication patient, intractable case patient, field planting bacterium patient etc. more increases in vivo.These The expansion of crowd makes the crowd of clinical long-term endotracheal intubation increase severely.The band pipe time is longer, the generation of whole body or body part infection Rate is higher.The reasonability of the pipe depth is set, equally will affect the disease treatment and rehabilitation of patient.Trachea cannula position is too deep, can draw One-lung ventilation is played, position is excessively shallow, is easy to slip.Therefore, most reasonable manner is to carry out chest after being intubated to penetrate piece, according to rabat Suggested trachea cannula end-position level judged, too deep or shallowly give advance and retreat trachea cannula excessively.Once adjusting aerobic The depth of cannula, the exposed length of trachea cannula are the key indexes for judging trachea cannula and whether shifting.

Due to the scale that existing trachea cannula is printed on, to be inserted to tracheae from balloon side to the high range extended in vitro Managing in vivo or external length cannot precisely embody.It is outer will to measure intubation by the patient of long-term endotracheal intubation when relieving Reveal length (exposed length is distance of patient's front tooth to the exposed end of intubation)；Before and after carrying out common oral care, also to measure It is intubated protruded length, prevents dislodged cannula.If measuring protruded length with ruler, operator's gimmick is different, influences measurement result. The ruler that measurement is used simultaneously, it is difficult to guarantee effective disinfection, it is interpatient to be used alternatingly, it is easier to that cross-infection, shadow occurs Ring patient's prognosis.

Chinese patent application: CN202069975U discloses a kind of Anti-biting adult tracheal intubation with identification layer, including Trachea cannula ontology is equipped with anti-bite identification layer at the place of the 22-24cm of trachea cannula, and anti-bite identification layer is externally provided with soft tooth and protects Sheath.But scale marker is not arranged for the patent, inconvenient for use.

Chinese patent application: CN203329166U, which discloses one kind, disposably has scale sputum aspirator tube, specifically includes that scale is inhaled Phlegm pipe, tracheal cannula sleeve, tracheostomy cannula, scale sputum tube joint, there are two scales on scale sputum aspirator tube, are respectively: One scale of sputum aspirator tube, two scale of sputum aspirator tube, the length of one scale of pipe are equivalent to the length of tracheostomy cannula, two scale of sputum aspirator tube Length be equivalent to the length of tracheal cannula sleeve, but the patent is mainly used for the suction sputum of patient, and the scale of the patent Design direction is consistent.

Therefore, in view of the foregoing drawbacks, it is extremely urgent to develop a kind of bidirectional measurement trachea cannula.
