Further, a sealing ring 13 is fixed on the inner side wall of the bottom end of the casing 11 in a melting mode, and the sealing ring 13 is obliquely arranged.

Specifically, when base 1 installs on endotracheal tube and endotracheal tube deepened the inboard of base 1 completely, endotracheal tube's lateral wall joint is arrived between ring chock 12 and sealing washer 13, makes base 1 and endotracheal tube both be connected firmly and tightly, improves the leakproofness.

In this embodiment, the outer diameter of the convex ring 111 is equal to the inner diameter of the large piston cap 21, and the inner diameter of the convex ring 111 is equal to the outer diameter of the large plug 211.

Specifically, when the half plug 2 is closed, the convex ring 111 is sleeved outside the large plug 211 and clamped inside the large piston cover 21, so that the large piston cover 21 can be stably and tightly clamped and matched with the housing 11, and half plugging operation is facilitated, and at this time, the size of the vent hole is reduced from the inner size of the original convex ring 111 to the size of the half plugging vent hole 212.

Further, integrated into one piece has first connecting band 22 on big piston cap 21's the lateral wall, and one side integrated into one piece that first connecting band 22 was kept away from to big piston cap 21 lateral wall has first plectrum 23, makes 2 overall structure of half stifled piece durable firm, and is convenient for open and shut.

Specifically, the other end of the first connecting band 22 is fusion-fixed to the outer side wall of the jacket 11, and the half plugs 2 can be prevented from falling or being lost.

In this embodiment, the small plug 311 is adapted to the size of the semi-closed vent 212.

Specifically, when the full plug 3 is closed, the small plug 311 is in clamping fit with the half-plug vent 212, and the half-plug vent 212 is plugged through the small plug 311, so that the full plug effect is realized.

Further, a second connecting band 32 is integrally formed on the outer side wall of the small piston cover 31, and a second shifting piece 33 is integrally formed on one side of the outer side wall of the small piston cover 31, which is far away from the second connecting band 32, so that the whole structure of the full plugging piece 3 is firm and stable, and the opening and closing are convenient.

Specifically, the other end of the second connecting band 32 is fusion-fixed on the outer side wall of the large piston cap 21, so that the dropping or loss of the full plugging member 3 can be avoided.

In this embodiment, the top surface of the fixing band 4 is fixed with the thorn face sticker 41 near the outer end by glue adhesion, and the top surface of the fixing band 4 is fixed with the hair face sticker 42 near the inner end by glue adhesion.

Further, in the use, install stifled pipe device on endotracheal tube closely reality earlier, pass the both sides mounting hole of extratracheal tube stationary blade respectively with two fixed bands 4 again, then paste thorn face subsides 41 on its matte face subsides 42 that correspond the position, be convenient for install and dismantle.

In this embodiment, the outside of connecting pipe 5 comprises a plurality of integrated into one piece's radius platform, and reduces in proper order from last radius platform size that distributes extremely down, makes the whole of connecting pipe 5 be type coniform, is convenient for carry out stifled pipe to the pipe of different internal diameters, enlarges its application scope, improves its practicality.

Further, the inside wall of connecting pipe 5 is smooth level and smooth, is convenient for ventilate, and can avoid patient's sputum etc. to be detained and probably appear the backward flow or arouse the infection in connecting pipe 5.

Specifically, the size of the top surface of the connecting pipe 5 is the same as the size of the bottom surface of the annular chock 12, and the connecting pipe 5 is melt-bonded with the annular chock 12, so that the connecting pipe 5 is firm and stable, and the size of the connecting pipe is matched with that of the base 1.

In addition, in this embodiment, the base 1, the half plugging member 2, the full plugging member 3, the fixing band 4 and the connecting tube 5 are preferably made of medical grade silicone rubber, and the material thereof is soft, elastic, wear-resistant, durable, and good in waterproofness and sealing performance.

Example 2

Referring to fig. 6-7, based on embodiment 1, the present invention provides a technical solution:

the utility model provides a metal endotracheal tube stifled pipe device, including base 1, base 1 includes cover 11, integrated into one piece has bulge loop 111 in the middle of cover 11's the top, be equipped with half stifled piece 2 directly over base 1, half stifled piece 2 includes big piston cover 21, integrated into one piece has big chock 211 in the middle of the inboard top surface of big piston cover 21, the centre of big chock 211 is equipped with half stifled air vent 212, be equipped with full stifled piece 3 directly over half stifled piece 2, full stifled piece 3 includes little piston cover 31, integrated into one piece has little chock 311 in the middle of the bottom surface of little piston cover 31, regular melting is fixed with two fixed bands 4 on base 1's the lower extreme lateral wall.

Specifically, the external diameter of ring chock 12 and endotracheal tube's internal diameter looks adaptation, the internal diameter of cover 11 and endotracheal tube's external diameter looks adaptation, when base 1 installs on endotracheal tube, endotracheal tube's lateral wall joint is between the lateral wall of ring chock 12 and cover 11's inside wall, and sealing washer 13 can improve the closeness of being connected between endotracheal tube and the base 1 this moment.

Wherein, the sealing ring 13 that sets up in an inclined manner makes the endotracheal tube deepen more in cover 11, and the inseparabler that connects, can effectively improve the connection leakproofness between the two.

In addition, the conical connecting pipe is omitted, special purpose for special pipes can be realized, and the probability of cross infection possibly occurring in the pipe blocking device used in combination with different guide pipes is reduced.

The utility model discloses a stifled pipe device of metal endotracheal tube is when using, to the patient that needs the tube drawing, at first take stifled pipe device, insert connecting pipe 5 in the endotracheal tube, and jam as far as possible, secondly draw tightly to paste fixedly after passing the both sides mounting hole on the outer pipe stationary blade of trachea with two fixed bands 4 respectively, again carry out half stifled pipe in proper order and stifled pipe operation can, stifled pipe in-process, the patient if feel uncomfortable or breathing difficulty, then can open full closure 3 or half closure 2 by oneself and ventilate.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. The technical personnel of this trade should understand, the utility model does not receive the restriction of above-mentioned utility model, and what describe in above-mentioned utility model and the description only does the preferred example of the utility model to need not restrict the utility model, under the prerequisite that does not deviate from the spirit and scope of the utility model, the utility model discloses still can have various changes and improvement, these changes and improvement all fall into the scope of the utility model that claims.
