Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a connecting pipeline for ventilation therapy. Background Technology
[0002] Oxygen three-way connectors (or simply three-way connectors) are a common connecting tubing accessory in the field of ventilation therapy. They are typically used to connect ventilators, breathing tubing, and breathing masks. They can be used to monitor gas pressure and flow at the mask or equipment end, connect external oxygen, increase exhaust gas, and increase CO2 emissions.
[0003] Currently, the T-connector design is too limited in its testing function, only measuring a single function. Experienced medical staff use silicone tubing with an external Y-shaped T-connector to achieve "dual measurement in one port" functionality. If this method is not used, and two or more functions (such as pressure measurement, flow measurement, oxygen connection, etc.) need to be performed simultaneously, two or more T-connectors are required. Both of these solutions increase the workload of medical staff and the number of accessories used, adding weight and length. This causes inconvenience for both medical staff and patients during use.
[0004] Application number CN202223153989.9 discloses an oxygen mask comprising a mask body, a fixing strap, and a nasal cannula. The mask body is placed over the patient's mouth and nose. The two ends of the fixing strap are fixed to the sides of the mask body. The nasal cannula extends into the mask body from the lower part. A connecting tube connecting the inside and outside of the mask body is provided on one side of the lower part of the mask body. A four-way fitting is detachably connected to one end of the connecting tube outside the mask body. The four-way fitting includes a first interface for detachable connection to the connecting tube, a second interface for connection to a nebulizer, a third interface for connection to an oxygen supply device, and a fourth interface for connection to a closed suction catheter. The disclosed four-way fitting is designed for use on a mask and has a cross-shaped structure, which limits its application. Utility Model Content
[0005] The technical problem this invention aims to solve is that when measuring data in a pipeline, the presence of only one multi-functional pipe makes measurement cumbersome.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] First, a connecting tubing for ventilation therapy is provided, including a tubing body for connecting a breathing mask and a breathing tubing, wherein the breathing tubing is connected to a breathing support device, and at least two multi-functional interfaces are provided on the side of the tubing body, wherein the axial spacing of the multi-functional interfaces is 0-20mm.
[0008] The pipeline body can simultaneously measure multiple data points through multiple multi-functional interfaces, which is convenient for users. The reasonable size design ensures that when oxygen is introduced into the multi-functional interface, the measurement results are less affected when other measuring devices are connected to the multi-functional interface, making it safer and more reliable to use.
[0009] Furthermore, the pipe body is provided with two multi-functional interfaces, which are arranged side by side along the busbar direction of the pipe body; the two multi-functional interfaces arranged side by side make it more convenient for users to connect measuring equipment and make operation easier.
[0010] Furthermore, the pipe body is provided with two multi-functional interfaces, which are symmetrically arranged along the pipe body; the symmetrical arrangement of the two multi-functional interfaces makes manufacturing more convenient and helps to improve production efficiency.
[0011] Furthermore, the multi-functional interface is integrally formed with the pipe body, and the included angle α between the outer wall of the multi-functional interface and the outer surface of the pipe body is 91° to 95°. The integral forming makes it convenient for users to manufacture in one go, saving costs and improving production efficiency. At the same time, the selection of the α angle also makes the device easy to demold and facilitates production.
[0012] Furthermore, the pipe body and the multi-functional interface are made of polycarbonate.
[0013] Furthermore, a plug is provided at the outer end of the multi-functional interface; the plug seals the multi-functional interface to prevent air leakage, so that the multi-functional interface does not affect the use of the pipeline body when it is not in use.
[0014] Furthermore, a ring is fitted onto the multi-functional interface, and the ring is connected to the plug via a connecting arm; this fixes the plug onto the multi-functional interface, preventing the plug from being lost and making it more convenient for the user to use.
[0015] Furthermore, the multi-functional interface is provided with a retaining ring for limiting the position of the ring, and the retaining ring is integrally formed with the multi-functional interface; the retaining ring is used to prevent the ring from falling off, making the ring more stable on the multi-functional interface.
[0016] Furthermore, the multi-functional interface extends outward from the pipe body by 9.0 to 12.0 mm, and the outer diameter of the multi-functional interface is 3.8 to 4.8 mm; the selection of the size of the multi-functional interface facilitates a tight fit with the plug, so as to prevent the plug from popping out under high pressure.
[0017] Furthermore, there are three multi-functional interfaces, two of which are symmetrically arranged along the pipe body, and the third multi-functional interface is arranged side by side with any one of the other multi-functional interfaces.
[0018] This invention has the following advantages: By setting at least two multi-functional interfaces, compared with conventional three-way pipes, this invention can realize dual-line measurement tasks, reduce the use of respiratory accessories, and reduce the workload of medical staff; at the same time, the limited range of the axial distance between the multi-functional interfaces also reduces the measurement error between the multi-functional interfaces, making the device more stable and reliable to use; at the same time, the setting of the plug also allows the pipe body to work normally when the multi-functional interfaces are not in use, making the device adaptable to different situations.

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] It should be noted that all directional indicators in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.
[0027] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] This utility model provides a connecting pipeline for ventilation therapy, such as Figure 1 and Figure 2 As shown, it includes a tubing body 10, wherein one end of the tubing body 10 is connected to a breathing mask and the other end is connected to a breathing tubing, which can be connected to a breathing support device.
[0030] To facilitate the measurement of various data in the pipeline body 10, such as pressure, flow rate, or oxygen connection, at least two multi-functional interfaces 11 are provided on the side of the pipeline body 10. Depending on the actual use, the number of multi-functional interfaces 11 should not exceed three. The pressure, flow rate, or oxygen connection in the pipeline body 10 can be measured simultaneously through multiple multi-functional interfaces 11.
[0031] In this embodiment, for ease of manufacture and practical use, the multi-functional interface 11 extends outward from the pipe body 10 by a length of 9.0 to 12.0 mm. When the multi-functional interface 11 is not in use, it needs to be sealed. To facilitate sealing the multi-functional interface 11, a plug 12 is provided at the open end of the multi-functional interface 11. The plug 12 seals the multi-functional interface 11, ensuring that the pipe body 10 can be used normally when no other external equipment is needed.
[0032] To prevent the plug 12 from being lost, a connecting arm 13 is installed on the plug 12, and a ring 14 is installed at the end of the connecting arm 13 and fitted onto the multi-functional interface 11. The ring 14, the connecting arm 13 and the plug 12 are integrally formed and made of silicone material.
[0033] In this embodiment, in order to ensure that the plug 12 can be stably installed on the multi-functional interface 11, wherein the outer diameter of the multi-functional interface 11 is 3.8 to 4.8 mm, the plug 12 can be securely fastened to the multi-functional interface 11.
[0034] To prevent the ring 14 from slipping off the multi-function interface 11 and causing the plug 12 to be lost, an annular retaining ring 15 is provided on the outer wall of the multi-function interface 11. The retaining ring 15 holds the ring 14 on the multi-function interface 11. The difference between the inner diameter and the outer diameter of the retaining ring 15 is 1 to 2.5 mm. The retaining ring 15 and the multi-function interface 11 are integrally formed.
[0035] In this embodiment, when one of the multi-function interfaces 11 is connected to oxygen and the other multi-function interfaces 11 are connected to measuring instruments to measure the pressure, flow rate, etc. in the pipeline body 10, the introduced oxygen will have a certain impact on the measurement results. In order to reduce the impact, the closer the multi-function interfaces 11 are to each other, the smaller the impact will be. That is, the smaller the axial spacing of the multi-function interfaces 11, the better. The axial spacing between the multi-function interfaces 11 is between 0 and 20 mm.
[0036] like Figure 4 As shown, when there are two multi-functional interfaces 11, and the axial distance between the multi-functional interfaces 11 is less than the diameter of the multi-functional interfaces 11, the multi-functional interfaces 11 can be staggered. In this embodiment, for ease of manufacturing, the multi-functional interfaces 11 are symmetrically arranged along the pipe body 10.
[0037] like Figure 3 As shown, when there are two multi-function interfaces 11, and the axial distance between the multi-function interfaces 11 is greater than the diameter of the multi-function interfaces 11, the multi-function interfaces 11 can be arranged side by side. Different forms can be selected according to the actual use to ensure that measurement errors are reduced.
[0038] like Figure 5 As shown, when there are three multi-functional interfaces 11, the three multi-functional interfaces 11 can be arranged in the same plane along the outer side of the pipe body 10. Considering the actual manufacturing problem, two of the multi-functional interfaces 11 can be arranged symmetrically along the pipe body 10, and the third multi-functional interface 11 can be arranged side by side with any one of the multi-functional interfaces 11.
[0039] The pipe body 10 and the multi-functional interface 11 are integrally molded. In order to balance cost, hardness and ductility, the pipe body 10 and the multi-functional interface 11 are made of polycarbonate (PC material) with high transparency.
[0040] like Figure 5As shown, since the entire device is integrally molded, in order to facilitate demolding, the included angle α between the outer wall of the multi-functional interface 11 and the outer side of the pipe body 10 is 91° to 95°.
[0041] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
