Abstract

A reverse guide tube for intercricocentesis is composed of a tubular arc main body and a handle linked to the rear end of said main body and with horizontal wings. Said main body has a closed front tip end with tangent guide slot, an air inlet hole close to tip end, and the length graduation lines and vector lines close to handle. A pair of opening pliers for said reverse guide tube is also disclosed, which has a curved surface matched with said guide slot of reverse guide tube and a cutting edge.

Description

Thyrocricoid puncture reverse leading pipe and strut pincers matching used with it

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly a kind of tracheotomy guiding tube and strut pincers matching used with it.

Background technology

In battlefield and some scene of the accident, wounded body can respiratory tract obstruction occur and suffocate, and rescue and must seize every minute and second this moment because the people suffocate 2～4 minutes will cardiac arrest, irreversible degeneration appears in brain.Present tracheotomy device all will be operated by the doctors and nurses, do not send before the personnel of protecting or medical personnel arrive in battlefield or the scene of the accident, must rescue the life of wounded body 2～4 minutes time rapidly, need a kind of quick tracheotomy device of design, and finish by non-medical personnel's operation.Directly carry out trachea puncture but not medical personnel are very difficult, prick and just be not easy to damage the both sides trunk, and can make the thyroid place hemorrhage many at cervical region.

Summary of the invention

Purpose of the present invention just provides a kind of thyrocricoid puncture reverse leading pipe and strut pincers matching used with it, can be by the needs of non-medical personnel's operation to satisfy the field first aid occasion.

Technical scheme of the present invention is: a kind of thyrocricoid puncture reverse leading pipe, comprise arcual tubular body, be provided with the tip of sealing at the front end of this main body, be provided with tangential guide recess, be provided with air inlet in the outside near most advanced and sophisticated place of described main body in this outside, tip; Be provided with handle and horizontal tail in the rear end of main body, be provided with the breather interface, be provided with length scale at the back side along its length direction near the main body of described handle at this handle rear end.In the middle of the curved inboard outside of the arc of described main body, be provided with the center sagittal line.

Be connected with feeder at described breather interface, this device comprises connection tube, air storage bag and inflator, and described breather interface is connected with the gas outlet of air storage bag by connection tube, and the air inlet of this air storage bag is connected with the outlet of described inflator.

A kind of thyrocricoid puncture special use struts pincers, comprises jaw and pincers handle, and a side of described jaw is provided with the curved surface that coincide with the guide recess in the outside, described guiding tube tip, is provided with the incision sword along length direction in the middle of the opposite side of jaw.

The invention has the beneficial effects as follows: because ring first film has a recess, so everyone can both touch, and ring first film recess is nearest with air flue, so penetrate the trachea accurate positioning from this, operates easily, is suitable for non-medical personnel and operates.The thyrocricoid puncture guiding tube is entered trachea in case puncture, because the air inlet on the guiding tube main body can be to the trachea bubbling air, patient's upper respiratory tract is blocked immediately to take a turn for the better, there has been the competent time to carry out follow-up operation, had great advantage than at present domestic and international up-to-date " percutaneous expansion tracheal intubation ".Also can utilize inflator, air storage bag and breather to be pressed into air to the guiding tube main body, a people just can operate, and can improve the success rate of rescuing critical patient in the open air greatly.

The specific embodiment

Referring to Fig. 1～Fig. 3, be a kind of thyrocricoid puncture reverse leading pipe of the present invention, comprise arcual tubular body 1, be provided with the tip 3 of sealing at the front end of this main body 1, be provided with tangential guide recess 5 in this outside, tip, can allow strut pincers and insert trachea along groove.The outside at close most advanced and sophisticated 3 places of described main body 1 is provided with several air inlets 4; Be provided with handle 2 and horizontal tail 16 in the rear end of main body 1, be provided with center sagittal line 17 in the middle of the curved inboard outside of the arc of main body 1, horizontal tail 16 and sagittal line 17 can guarantee that the tip 3 of guiding tube enters the direction of trachea.And horizontal tail 16 also can be worked as handle, the action of conveniently flipping.Get the rear end at this handle 2 and be provided with breather interface 15, interface 15 adopts and is suitable for and hose connection structure, as annular ridge.Be provided with length scale 10 at the back side of main body 1 near described handle 2 places along its length direction.Scale 10 on the thyrocricoid puncture guiding tube can make the operator see the degree of depth that enters skin,

Referring to Fig. 4, the also configurable easy feeder of the present invention, feeder comprises connection tube 6, air storage bag 7 and inflator 8, and the breather interface 15 of described guiding tube is connected with the gas outlet of air storage bag 7 by connection tube 6, and the air inlet of this air storage bag 7 is connected with the outlet of inflator 8.Air storage bag 7 can store the gas of being got by inflator 8, with air feed equably.

Referring to Fig. 5 and Fig. 6, what represent is that a kind of thyrocricoid puncture special use of the present invention struts pincers, comprise jaw 91 and pincers handle 92, the upside of described jaw 91 is provided with the curved surface 93 that coincide with the guide recess 5 in the outside, described guiding tube tip, is provided with the incision sword 94 along length direction in the middle of the downside of jaw 91 is provided with.

Referring to Fig. 7～Fig. 9, the concrete operating procedure of the present invention when using is as follows:

The wounded is lain on the back, do not need head layback, touch cervical region Adam's apple (being thyroid cartilage 11 places) and can touch downwards a recess is arranged between thyroid cartilage and the cricoid cartilage, D penetrates thus with the thyrocricoid puncture guiding tube, squeeze into air with inflator 8, patient's upper respiratory tract blocks phenomenon to be improved immediately.Air is propped up air storage bag 7, the major axis of guiding tube tip 3 to lower edge trachea 14 advanced inwards, because guiding tube D is arc, most advanced and sophisticated 3 upwards needle skin naturally and wear out when advancing, the position that passes is generally between 2 and 3 annulus trachealises, or between 3 and 4 annulus trachealises.Insert with the groove 5 of the curved surface 93 that struts pincers 9 jaw 91 along most advanced and sophisticated 3 back sides of guiding tube, vertically cut off earlier about 1～2 centimetre of skin downwards, strutting pincers 9 inserts in the trachea 14, this is strutted flatly, reuse ordinary rigid tracheal intubation 18, insert in the trachea 14 also fixing, bloody sputum in the trachea is blotted only connecting flexible pipe 6 under 15 groups thyrocricoid puncture guiding tube interfaces, be connected on the tracheal intubation 18, inflator 8 continues to inflate, guarantee that tracheal intubation 18 is accurate in trachea, transfer to thyrocricoid puncture guiding tube D down, finished the rescue process from " Adam's apple ".
