Description

A kind of modified tracheal tube

Technical field

The present invention relates to the apparatus that patient respiration system is influenced with gas treating process, and in particular to tracheae is intubated.

Background technology

Clinically, imposing the patient of tracheotomy often needs to insert tracheal tube to keep respiratory passage unblocked.It is existing Tracheal tube includes casing, fixed-wing, air bag, gas tube and the pipette of arc, wherein, the fixed-wing is located at proximal end Outer wall；The air bag is located at the outer wall of boot proximal end；Described gas tube one end is through fixed-wing and the joining place of casing, along set The outer wall of pipe extends and is connected with air bag, and the other end is instruction sacculus and charge valve；The pipette near-end through fixed-wing with The joining place of casing, distally extends close to the near-end of air bag along the outer wall of casing.The present inventor has found in clinical practice, existing With the presence of following two big defect of tracheal tube：When patient or so turn over or acutely cough when, tracheal tube easily come off and There are security risk；It is described second, although saliva produced by patient can be suctioned out with the gastric content to backflow by pipette Saliva will flow through surgical wound, easily contaminated operation wound with the gastric content to backflow, when especially being the failure to suction out in time, operation Wound is just dipped in saliva and gastric content for backflowing etc. all the time to be had in the body fluid of bacterium, not only influences healing, it is also possible to cause soft group Knit infection to suppurate, cause serious mediastinal infection.

Authorization Notice No. is that the utility model patent of 204840586 U of CN discloses a kind of deformable air pipe sleeve with capsule Pipe, the deformable tracheal tube is " bottom of the middle bent portion of arc line shaped tracheal tube is equipped with the second cuff, described second set Capsule connects the second loading line, and second loading line is equipped with the second injecting hole, and second cuff causes after inflation The T-shaped pipe of arc line shaped tracheal tube ", efficiently solves existing tracheal tube and there is the risk that comes off.But if will be above-mentioned The design philosophy of second cuff disclosed in utility model patent be used for improve existing tracheal tube, it is clear that can not still overcome saliva with The gastric content to backflow will flow through the defects of surgical wound.

The content of the invention

The defects of for present in the above-mentioned prior art, technical problem solved by the invention are to provide a kind of modified gas Pipe-in-pipe, the modified tracheal tube have the advantages that the gastric content contaminated operation wound for avoiding saliva Yu backflowing.

The scheme that the present invention solves above-mentioned technical problem is as follows：

A kind of modified tracheal tube, the tracheal tube include the casing and fixed-wing, pipette, the first gas of arc Capsule, the second air bag and two gas tubes, wherein, the fixed-wing is located on the outer wall of proximal end, first air bag It is located on the outer wall of boot proximal end, second air bag is located at the back of the casing of the arc, and inflates the backward set The opposite direction extension that pipe is distally-oriented to；Two gas tubes are connected with the first air bag and the second air bag respectively；Its feature exists In,

After second airbag aeration, its distal diameter is more than the diameter of near-end, and by the tracheae glottis end seal of patient Close；The pipette is through being pierced by the distal end of the second air bag in second air bag.

Above-mentioned modified tracheal tube, it is characterised in that the pipette is adhered to it along the arc of described sleeve pipe One side, described two gas tubes are adhered to its another side along the arc of described sleeve pipe, and respectively by described solid Determine the wing to be pierced by with casing joining place.

Above-mentioned modified tracheal tube, it is characterised in that the near-end of the pipette is equipped with syringe interface.

Above-mentioned modified tracheal tube, it is characterised in that the near-end of the gas tube is equipped with pilot balloon, the instruction gas The import of capsule is equipped with charge valve.

Modified tracheal tube of the present invention has the advantages that compared with the prior art：

Dexterously using second air bag, in inflation, caused tension force send the pipette being pierced by through it to operation The top (i.e. towards the side of glottis) of wound, while tracheae is closed in the distal end being relatively large in diameter using pipette, in patient's mouth Caused saliva just accumulates in the distal end of the second air bag with the gastric content to backflow, thoroughly overcomes saliva existing in the prior art The defects of liquid and the gastric content contaminated operation wound to backflow and influence are healed.

Brief description of the drawings

Fig. 1~3 are the structure diagram of a specific embodiment of modified tracheal tube of the present invention, wherein, Fig. 1 For front view, Fig. 2 is rearview, and Fig. 3 is A-A cutaway view Amplified images in Fig. 1.

Embodiment

Referring to Fig. 1~3, whole tracheal tube includes casing 1, fixed-wing 2, pipette 5, the first air bag 3, the second air bag 4 With two gas tubes 6, wherein, casing 1 is arc, and fixed-wing 2 is set on outer wall at its proximal end, and the first air bag 3 is located at its distal end Outer wall on, the second air bag 4 is located at its back.

Referring to Fig. 1 and Fig. 2, the second air bag 4 is more than the pocket-like of mouth diameters for base diameter, its oral area is heat sealing at described The back of the casing 1 of arc, inflates the opposite direction extension that backward described sleeve pipe 1 is distally-oriented to, and by the tracheae glottis end of patient Closing.

Referring to Fig. 1~3, the distal end of the second air bag 4 is pierced by the second air bag of distal end 4 of pipette 5, middle part is along casing 1 arc heat seal is adhered to one side, is then pierced by from fixed-wing 2 and 1 joining place of casing, and near-end is equipped with syringe interface 7。

Referring to Fig. 1~3, the distal end of two gas tubes 6 connects 4 with the first air bag 3 and the second air bag respectively, and middle part is along set The arc heat seal of pipe 1 is adhered to its another side, is then pierced by from fixed-wing 2 and 1 joining place of casing, and near-end is equipped with instruction gas Capsule 8, the import of the pilot balloon 8 are equipped with charge valve 9.
