Abstract

The utility model relates to a respiratory tube structure which mainly comprises a tubular main body; a plurality of convex and concave expansion rings are arranged on the side wall of the tubular main body and are arranged at fixing intervals; both ends of the tubular main body are respectively provided with one joint; a truncation part is arranged at a proper distance at the rear part of the joint. The utility model with the structure can save cost and improve softness.

Description

The air tube structure

Technical field

The relevant a kind of air tube structure of this utility model refers to a kind of air tube of saving cost and promoting pliability that reaches especially.

Background technology

For using respiratory gas to solve patient's breathing problem, tracheal intubation or autogenous cutting sleeve pipe that patient uses are to be connected with an end of an air tube, the other end of this air tube is connected with a respiratory organ, and this respiratory organ must export oxygen to tracheal intubation or the autogenous cutting sleeve pipe uses so that patient to be provided by air tube.

As shown in Figure 3, known air tube mainly comprises a tubular body a, the sidewall of this tubular body a is provided with most the expansion ring a1 that are concavo-convex moulding, this expansion ring a1 arranges with fixed interval, and the sidewall of this tubular body a all is provided with one in the position of every interval one suitable distance and blocks the b of portion, is respectively arranged with a joint c in the two ends of this tubular body a in addition; According to above-mentioned structure, the joint c that known air tube utilizes two ends is connected with a respiratory organ and tracheal intubation or autogenous cutting sleeve pipe respectively, this blocks the b of portion and must be cut off by central part, its block b central authorities of portion both sides form a complete joint respectively, and the size of this joint just is the international standard of 22mm or 15mm, blocks between two joints that the b of portion forms in this and must insert a return-air valve; In addition, when joint c damages or air tube length when long, must this telescoping tube be cut off by one of them central authorities of blocking the b of portion, and this tubular body a utilizes expansion ring a 1 to make it crooked easily.

Because known air tube all is provided with one in the position of every interval one suitable distance and blocks the b of portion, the mould of therefore making this air tube will block the corresponding shape of the b of portion in each suitable distance setting and this, so will cause the increase of manufacturing cost; And being provided with this place of blocking the b of portion does not have expansion ring a1, and therefore being provided with this position of blocking the b of portion can't be crooked arbitrarily, causes its pliability relatively poor, in the use quite inconvenience.

Summary of the invention

Main purpose of the present utility model is to provide a kind of air tube structure of saving cost and promoting pliability that reaches.

For reaching above-mentioned purpose, air tube structure of the present utility model mainly comprises a tubular body, the sidewall of this tubular body is provided with most the expansion rings that are concavo-convex moulding, and this expansion ring is arranged with fixed interval, be respectively equipped with a joint in the two ends of this tubular body, suitably distance is provided with one and blocks portion at this joint rear one.

According to above-mentioned structure,, therefore when bending, more can not be subjected to the obstruction of the portion of blocking because air tube structure of the present utility model tubular body wherein only suitably blocks portion apart from being provided with one at the rear one of two end connectors; And on making, its mould only need be provided with two and block the corresponding shape of portion with this, therefore can reduce die cost, to reach the effect of saving cost and lifting pliability.

The specific embodiment

Structure of the present utility model, device and feature thereof are lifted a preferable possible embodiments and are cooperated graphic being described in detail as follows:

Fig. 1, shown in Figure 2 please arrange in pairs or groups, air tube structure of the present utility model, mainly comprise a tubular body 1, the sidewall of this tubular body 1 is provided with most the expansion rings 10 that are concavo-convex moulding, and this expansion ring 10 is spaced with fixed range, be respectively equipped with a joint 11 in the two ends of this tubular body 1, and suitably block portion 12 apart from being provided with one at these joint 11 rears one.

According to above-mentioned structure, air tube structure of the present utility model, the joint 11 that utilizes two ends is connected with a respiratory organ 2 and tracheal intubation or autogenous cutting sleeve pipe 3 respectively, when joint 11 damages or air tube when long, must do cut-out by the central authorities that two or one of them are blocked portion 12, make these central both sides of blocking portion 12 form a complete joint 11 respectively, block between two joints 11 that portion 12 forms in this that again a return-air valve 4 being set.

As mentioned above, air tube structure of the present utility model tubular body 1 wherein only suitably blocks portion 12 apart from being provided with one at the rear one of two end connectors 11, therefore this utility model more can not be subjected to the obstruction of the portion of blocking 12 when bending, and must reach the effect of promoting pliability.

Moreover, because air tube structure of the present utility model, only be provided with two and block portion 12, therefore on making, its mould only need be provided with two and block portion's 12 corresponding shapes with this, thus can effectively reduce die cost, to reach cost-effective effect.

Claims

1. air tube structure, comprise a tubular body, it is characterized in that: the sidewall of this tubular body is provided with most the expansion rings that are concavo-convex moulding, this expansion ring is spaced with fixed range, be respectively equipped with a joint in the two ends of this tubular body, and at described joint rear one suitably distance be provided with one and block portion.
