Description
Technical field
This utility model relates to a kind of electrolaryngoscope, particularly a kind of electrolaryngoscope of adjustable tracheal cartilages socket length.
Background technology
Electrolaryngoscope is generally made up of photographic head, hollow stereoplasm tube (or claiming " connecting rod "), handle and control display module; The front end of hollow stereoplasm tube is provided with photographic head, and its rear end is fixedly connected with handle, can admittance line in its pipe; The rear end part of handle is connected with control display module.In the diagnosis and treatment process using electrolaryngoscope, the general supporting tracheal cartilages of electrolaryngoscope (or claim " tracheal intubation ", or " endotracheal tube ", or " insertion tube ") use, hollow stereoplasm tube by electrolaryngoscope inserts in tracheal cartilages, tracheal cartilages circumference is coated with photographic head and hollow stereoplasm tube, gos deep into patient cavum laryngis in after being socketed with handle.
But in diagnosis and treatment process, because the specification of tracheal cartilages is more, the length between tracheal cartilages with hollow stereoplasm tube is mated becomes more scabrous problem.According to " the People's Republic of China (PRC) pharmaceuticals industry standard YY0337.1-2002 " regulation to tracheal cartilages, tracheal cartilages, because of its internal diameter and different from the length that internal diameter matches, has 19 kinds of specifications.
Therefore, in the matching process of tracheal cartilages and hollow stereoplasm tube, if the top end face of tracheal cartilages exceeds hollow stereoplasm tube, to be provided with the end face of photographic head one end too much, one end that tracheal cartilages gos deep into patient's cavum laryngis inside will lose the support of hollow stereoplasm tube to it, is unfavorable for that the entirety of tracheal cartilages is inserted smoothly; Long tracheal cartilages also can block the sight line of photographic head, affects the operation of medical personnel to electrolaryngoscope further.
And if the spacing of the top end face of tracheal cartilages and photographic head is too small, likely makes the Mo Feikong at the position, front end of tracheal cartilages be blocked, make Mo Feikong lose due effect, i.e. expectoration function; When spacing is little of when making the top end face of tracheal cartilages be positioned at photographic head rear, now photographic head stretches out the coated scope of tracheal cartilages, and contact with the bottleneck throat of patient, so not only can damage the cavum laryngis portion of patient or discomfort, but also photographic head can be made directly to be attached to the wall of laryngeal cavity of patient, make photographic head not carry out camera work.
In order to solve the problems of the technologies described above, existing counte-rplan are equipped with a electrolaryngoscope with corresponding hollow stereoplasm tube length specially for the tracheal cartilages of often kind of specification, but the cost implementing this scheme is quite high, the operation of medical personnel is also more complicated, popularizing of unfavorable electrolaryngoscope.
Chinese invention patent application CN102764472A discloses a kind of stereoplasm tube laryngoscope being applicable to many specifications tracheal intubation, comprise: the stereoplasm tube of handle and hollow, one end of handle and one end of stereoplasm tube are connected, stereoplasm tube outer peripheral face is socketed with positioning body, positioning body is round table-like, the cone angle of positioning body is 1 ° to 3 °, and the large end of positioning body is near handle.
In brief, foregoing invention application is the length of fit being regulated tracheal cartilages and hollow stereoplasm tube by the pyramidal structure of positioning body.But this technical scheme has following defect.
1, the limited types be suitable for, still needs apolegamy.The cone angle of positioning body can only be a fixed value, and therefore a kind of positioning body can only be suitable for the tracheal cartilages of limited money caliber specification.To use the tracheal cartilages of other a few money specification, the positioning body that the another kind that just must change the outfit matches.
As described in the description of this patent application, " tracheal intubation is divided into 19 kinds of specifications according to internal diameter from 2mm to 11mm, and the difference in internal diameters distance between adjacent two kinds of specifications is 0.5mm; Internal diameter 2.5mm to 5.5mm, length difference distance between the adjacent two kinds of specifications of tracheal intubation of 7mm to 9.5mm is 10mm, length difference between the adjacent two kinds of specifications of tracheal intubation of internal diameter 5.5mm to 7mm is apart from being 20mm, and the length between the adjacent two kinds of specifications of tracheal intubation of internal diameter 2mm to 2.5mm, 9.5mm to 11mm remains unchanged.The internal diameter of the tracheal intubation that Hospitals at Present is commonly used is between 4mm to 9mm, the length difference can knowing the adjacent two kinds of specifications of tracheal intubation of internal diameter 4mm to 9mm by inference is respectively 10mm and 20mm two kinds, the cone angle being scaled positioning body is respectively 1.43 ° and 2.86 °, by the tracheal intubation that the positioning body of the cone angle 1.43 ° length difference distance of mating between adjacent two kinds of specifications is 20mm, by the tracheal intubation that the positioning body of the cone angle 2.86 ° length difference distance of mating between adjacent two kinds of specifications is 10mm, the outer face of stereoplasm tube to Patients Underwent Endotracheal Intubation end outer face distance is made to remain at about 10mm like this.”
Compared with prior art, the technical scheme of this patent application still needs matching process.And convert and matching process more complicated, medical personnel need relevant training just likely to remember or skilled associative operation.
2, complex operation, dismounting inconvenience.
When a kind of positioning body does not mate the specification of tracheal cartilages, just need to dismantle it, be loaded on the positioning body of another kind of coupling.Aforesaid operations comprises the processes such as dismounting, coupling, installation, not only wastes time and energy, and easily makes mistakes.
3, tracheal cartilages easily damages, and easily comes off from electrolaryngoscope.
The tracheal cartilages mode be fixed on positioning body is that the mouth of pipe contacted with positioning body by tracheal cartilages is supportted greatly gradually, and tracheal cartilages is connected in an interference fit with positioning body.Well imagine, this fixed structure not only easily causes the body of tracheal cartilages to break, and easily from landing the cone inclined-plane of positioning body, causes danger to patient.
To sum up, the technical scheme of tracheal cartilages socket length is adjusted in current prior art, the operation that electrolaryngoscope that is quick, simple, accurate, that be easy to left-hand seat mates with tracheal cartilages cannot be realized, and whole medical treatment apparatus fastness in use after coupling and security reliability poor, use rear dismounting also inconvenient.
