Tracheal structures available for connection with adapters of unequal diameters

technical field

The utility model relates to a trachea structure which can be connected with adapters with unequal pipe diameters, in particular to a trachea structure which can be inserted and connected with adapters of various specifications.

Background technique

Generally, the oxygen cylinder and the oxygen mask in the hospital are usually connected through a trachea so that the patient can inhale the oxygen in the oxygen cylinder from the oxygen mask. The adjustment of the trachea and the high mobility required by emergency patients are usually cut to various lengths according to the needs of the actual use environment, and then connected to the connectors of the oxygen mask and the oxygen cylinder for use. However, in this way, the practicability of wards and beds will be greatly restricted, and the most effective allocation and use cannot be obtained.

In order to effectively solve the above-mentioned problems, the industry often needs to use an adapter to connect with another air pipe in series to increase the required corresponding length. However, the adapters currently used in the trachea have a variety of pipe diameters, so that it is necessary to prepare pipes with multiple inner diameters at the same time as the corresponding cooperation, which causes inconvenience to the user. , and the high cost burden of purchasing a variety of pipe bodies, so it has become an important research topic for relevant people in this industry to provide a trachea structure that provides various specifications of adapters for insertion and connection.

In view of the various problems arising in the above-mentioned known technologies, the designer has been engaged in this industry for many years and in the spirit of excellence, actively researches and improves, and provides a trachea structure that can be connected by adapters with different pipe diameters.

Utility model content

In order to solve the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a gas pipe structure that can be connected by adapters with different pipe diameters. Adapters of different specifications are cut and connected accordingly, which greatly improves the usability and convenience of the trachea structure.

In order to achieve the above purpose, the utility model provides a trachea structure that can be connected with adapters of different pipe diameters. The trachea structure is used for inserting and connecting various adapters of different specifications. The pipe body is integrally formed with a straight pipe section and tapered pipe sections formed at intervals on the straight pipe section. The diameter of the inner edge of each radial section of the tapered pipe section is larger than the inner diameter of the radial section of the straight pipe section.

Preferably, the diameter of the outer edge at the middle of the tapered pipe section is greater than the diameter of the outer edge at its first and last ends.

Preferably, the diameter of the inner edge at the middle of the tapered pipe section is greater than the diameter of the inner edge at its first and last ends.

Preferably, the length of the tapered pipe section is greater than the length of the straight pipe section.

Detailed ways

Regarding the features and technical content of the present utility model, please refer to the following detailed description and accompanying drawings, and the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present utility model.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are the three-dimensional appearance view, the cross-sectional view along line 2-2 and the cross-sectional view along line 3-3 of the present invention, respectively. The utility model provides a trachea structure that can be connected with adapters with unequal pipe diameters. The trachea structure has a hollow pipe body 10 on which a plurality of straight pipe sections 11 and a plurality of intervals are formed on two sides. Tapered pipe sections 12 between adjacent straight pipe sections 11 . The diameter D of the inner edge of each radial cross section of the tapered pipe section 12 is greater than the inner diameter d of the radial cross section of the straight pipe section 11 . In addition, the outer edge diameter at the middle of the tapered pipe section 12 is greater than the outer edge diameters at the first and last ends of the tapered pipe section 12, and the length of the tapered pipe section 12 is greater than the length of the straight pipe section 11, so that the pipe body 10 can be cut range has been enlarged. Furthermore, the diameter of the inner edge at the middle of the tapered pipe section 12 is greater than the inner diameter at the first and last ends of the tapered pipe section 12 , so that the adapters 4 with different pipe diameters (as shown in FIG. 4 ) are easy to connect.

Please refer to FIG. 4 , which is a three-dimensional exploded view of the utility model applied to various adapters with unequal pipe diameters. The trachea structure of the present utility model can be applied to the communication between the oxygen cylinder 2 and the oxygen mask 3, and one end of the oxygen cylinder 2 and the oxygen mask 3 is fixedly connected with trachea joints 21, 31 respectively, when the length of the used tube body 10 is not enough , and when it is necessary to make an extended connection, according to the diameter of each adapter 4, after cutting corresponding to the diameter of the inner edge of the tapered pipe section 12, the cut nozzle is sleeved on the adapter 4 (or 4') at one end. In this way, the connection between the pipe body 10 and the adapter 4 can be quickly completed to increase the length.

From the above description, it can be seen that the user can cut the tapered pipe section 12 of the pipe body 10, so that the adapters 4, 4' of various specifications can be connected accordingly, and the usability of the trachea structure can be greatly improved. and convenience; In addition, the trachea structure of the present utility model has the aforementioned advantages, compared with the known straight pipe body, the maximum diameter of the equal length and tapered pipe section 12 is equal to the outer edge diameter of the known straight pipe body Under certain conditions, the straight pipe section 11 of the present invention has a smaller cross-sectional area than the known straight pipe body, so that the overall weight is reduced and the relative cost is relatively low.

However, the above descriptions are only preferred feasible embodiments of the present utility model, and are not intended to limit the scope of the present utility model. All equivalent structural changes made by using the description of the utility model and the contents of the accompanying drawings are either directly or indirectly Applied to other related technical fields, all are included in the scope covered by the present utility model in the same way.
