For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0032] The first group of embodiments:
[0033] See Figures 1-3 , which are respectively the front view, cross-sectional view and partial enlarged view of the breathing pipeline in the first group of embodiments of the present utility model.
[0034] As Figure 1 , one end of pipeline 1 is provided with a user end joint 2 for connecting with the user interface, and the other end of pipeline 1 is provided with a device end joint 3 for connecting with the ventilation treatment device. Among them, the device end joint 3 can be directly connected to the ventilation treatment device, or can be connected to the pipeline of the ventilation treatment device, and there is no limitation here; the user interface can be a sealed or non-sealed patient interface device, specifically in the form of a breathing mask, nasal oxygen tube, etc., and the ventilation treatment device can be a ventilator, a high-flow humidified oxygen therapy instrument, etc.
[0035] The pipeline 1 includes a pipe body 4 composed of a thin film and a thread rib 5, and the thread rib 5 is wound around the outer peripheral wall of the pipe body 4. The thin film has a predetermined thickness, and the thread rib has a predetermined pitch and width, so that the vertical softness of the pipeline is greater than or equal to 50°. When the softness of the pipeline is greater than or equal to 50°, when it is used in cooperation with a user interface (such as a breathing mask), it can effectively reduce the pulling of the pipeline on the user interface, thereby effectively improving the comfort and compliance of the patient wearing. The "vertical softness" in the present utility model is defined as: when the fixed end of the pipeline is placed horizontally, when the length of the free end of the pipeline is 250CM, the angle at which the pipeline hangs down. The size of the angle value is: the included angle reading between the connection line of the midpoint of the longitudinal section of the root of the free end of the pipeline and the midpoint of the end face of the free end of the pipeline and the horizontal line. Specifically, it can be referred to Figure 7 for measurement in the Figure 7 way. The vertical softness of the pipeline shown in the pipeline in
[0036] is α, that is, in the embodiment of the present utility model, α≥50°. Figure 2 , Figure 3 In some embodiments of the present utility model, a plurality of thin film protrusions 6 are provided on the outer peripheral wall of the pipe body 4 along its extending direction; there are various ways to set the protrusions. The first one: at least one thin film protrusion is provided between any two adjacent thread ribs 5. A more convenient way for mass production is to provide one thin film protrusion between any two adjacent thread ribs 5. The second one: a plurality of thin film protrusions are arranged at intervals between some thread ribs (that is, no thin film protrusions are provided between some thread ribs). The setting method can be evenly spaced or non-uniform. The so-called uniformity can refer to the uniformity of the number of thin film protrusions in the thread rib intervals provided with thin film protrusions; it can also refer to the uniformity of the blank spaces in the thread rib intervals. For example, one or more thin film protrusions are provided every 2 intervals, or in some places, the interval is 1 interval, and in some places, the interval is 2 intervals. There is no limit here, and it can be set freely in combination.
[0037] The thin film protrusion 6 can be formed by molding during the extrusion molding of the pipeline 1. The protrusion height of the thin film protrusion 6 has a great influence on the softness of the pipeline 1. The higher the protrusion, the better the softness. Because the larger the thin film protrusion 6 is, the larger the turning radius of the pipeline bending is, so the pipeline is easier to bend, that is, the softer it is. When the pipeline 1 is provided with a suitable pitch and film thickness, the softness of the pipeline with the thin film protrusion 6 is greater than that of the pipeline without the thin film protrusion 6. The shape of the thin film protrusion 6 can be V-shaped or arc-shaped, or even circular arc-shaped.
[0038] To meet the standard requirements (tensile force for plastic deformation > 45 N), the thickness of the film on the tube body 4 in this embodiment can be between 0.05 mm and 0.2 mm. When different materials are used for the pipeline, it is necessary to separately calculate the optimal range of the film thickness that meets the above standard requirements for this material. When the pipeline material is determined, the flexibility of the pipeline focuses on the thickness of the film on the tube body 4 of the pipeline 1. The thinner the thickness, the more flexible the pipeline. Additionally, it also lies in the rationality of the thread pitch setting of the thread ribs and the height of the film protrusion 6. The higher the film protrusion 6, the better the flexibility.
[0039] In some embodiments of the present utility model, the material of the film includes at least one of POE, TPE, SEBS, EVA, PP, Hytrel, TPU or a mixture of several of them. The material of the thread rib 5 is similar to that of the film, and also includes at least one of POE, TPE, SEBS, EVA, PP, Hytrel, TPU or a mixture of several of them. In the case of the above materials, the optimal range of the film thickness is 0.16 ± 0.01 mm. This thickness range is the thinnest state that the film can be in on the premise of meeting the standard requirements (tensile force for plastic deformation > 45 N). When the film is in the thinnest state that meets the mechanical requirements, it can bring the best flexibility of the pipeline. As the film thickness increases, the flexibility of the pipeline will decrease.
[0040] The thread rib 5 in this embodiment has a certain thread pitch A and thread width B. Among them, the thread pitch A of the thread rib 5 can be between 5 mm and 7 mm, and the range of 6.2 mm - 6.5 mm is the best preferred range. The thread pitch indirectly affects the flexibility of the pipeline and the size of the film protrusion 6. When the thread pitch is relatively large, after compression, the film protrusion 6 will protrude above the outer diameter of the pipeline, thus affecting the appearance and wearing comfort; if the thread pitch is too small, the film protrusion 6 will become smaller, and thus the overall flexibility of the pipeline will decrease. Therefore, the thread pitch between 6.2 mm and 6.5 mm is the optimal solution.
[0041] The thread width B in this embodiment can be between 1.5 mm and 4 mm, and the range of 2 mm - 2.5 mm is the best preferred range. The thread rib 5 has a certain supporting strength. When the thread width is relatively narrow, its supporting strength is insufficient, and the pipeline is easily crushed. At the same time, when the thread rib 5 is narrower, the overall tensile force of the tube body will decrease and thus cannot meet the requirement of > 45 N plastic deformation; when the thread rib 5 is wider, although the supporting strength is sufficient, it will affect the appearance, the overall flexibility of the tube body, and the height of the film protrusion 6. Therefore, the thread width of 2 mm - 2.5 mm is the best preferred range.
[0042] In the embodiment of the present utility model, the threaded rib 5 and the pipe body 4 of the pipeline can be independent components respectively, and are bonded into one body by an adhesive bonding method; of course, the pipeline can also be integrally molded. Since the breathing pipeline structure of the present utility model is simple, compared with the existing design, there is no need to divide the pipeline into a soft section and a non-soft section by combining different materials, there is no need to distinguish the use direction, and problems such as the pipeline being pulled and broken are not likely to occur. Similarly, due to the simple structure of the entire breathing pipeline, the production efficiency is higher, which is beneficial to cost reduction and efficiency increase.
[0043] The second group of embodiments:
[0044] See Figures 4-6 , which are the front view, cross-sectional view and partial enlarged view of the breathing pipeline in the second group of embodiments of the present utility model respectively.
[0045] The difference between this group of embodiments and the first group of embodiments is that the film bulge 6 in this group of embodiments is a fold, and other parts have been described in detail in the first group of embodiments, so no further description will be given here. The fold bulge in this group of embodiments can be realized by compression at high temperature on the basis of the formation of the pipeline 1. Specifically, a compression process is added on the basis of the previous extrusion molding to form a fold-like bulge, and such a fold-like bulge can make the pipeline softer. In this group of embodiments, as Figure 6 , the preferred solution is: the maximum outer diameter E of the fold is less than or equal to the maximum outer diameter D of the threaded rib 5. In specific implementation, the fold is designed to have a certain arc, which can further effectively improve the comfort of users.
[0046] The embodiment of the present utility model also provides a ventilation treatment device, which includes a main machine and a user interface. The main machine and the user interface are connected through the breathing pipeline in the above embodiments. Among them, the main machine is usually a ventilation gas supply device. The connection between the main machine and the user interface and the above breathing pipeline can be a direct connection or a connection through other gas flow channels, such as a connection through other breathing pipelines. Due to the structural setting and parameter setting of the breathing pipeline of the present utility model, it has good softness. When it is used in cooperation with a user interface (such as a breathing mask), it can effectively reduce the pulling of the pipeline on the user interface such as a breathing mask, and can effectively improve the comfort and compliance of patients wearing. In addition, due to its simple structure, compared with the existing design, there is no need to divide the pipeline into a soft section and a non-soft section by combining different materials, there is no need to distinguish the use direction, and problems such as the pipeline being pulled and broken are not likely to occur. Similarly, due to the simple structure of the entire breathing pipeline, the production efficiency is higher, which is beneficial to cost reduction and efficiency increase.
[0047] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application.
[0048] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved. For those skilled in the art, the utility model can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
