Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a device for realizing heating function for breathing tubing of various specifications. Background Technology

[0002] In the medical field, breathing circuits are an indispensable part of mechanical ventilation, oxygen therapy, and other treatments. Among them, breathing circuits with heating wires are respiratory assist devices used in anesthesia and emergency procedures. Their main function is to deliver oxygen and anesthetic gases into the patient's body. A key feature is that the heating wire heats the delivered gas to a suitable temperature, reducing irritation and discomfort for the patient. Simultaneously, it possesses good flexibility and high-temperature resistance, maintaining stable gas delivery during use. Breathing circuits with heating wires typically consist of a breathing tube, connecting tube, heating wire, and connectors. The breathing tube is the main channel for gas delivery and is generally made of soft materials to ensure patient comfort. The connecting tube connects the breathing tube to a ventilator or oxygen concentrator, serving the purpose of gas delivery. The heating wire is located inside the breathing circuit and raises the gas temperature through heating. The connectors are used to connect the breathing circuit to the ventilator or oxygen concentrator.

[0003] Due to the different designs and production of connectors by different manufacturers, there are a wide variety of specifications for breathing tubing on the market. Different heating devices for breathing tubing can often only be adapted to specific specifications of tubing, which limits their application range. Replacing tubing is also cumbersome, especially during the electromagnetic compatibility testing process. Because there are many breathing tubings that need to be registered, and each type of breathing tubing requires a corresponding heating ventilator to heat it, the testing process becomes cumbersome. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a device for heating breathing tubing of various specifications, so as to achieve the effect of heating breathing tubing of various different specifications using the same device without the need to provide multiple corresponding heating ventilators for heating breathing tubing.

[0005] The technical solution adopted by this utility model is a device for realizing heating function for breathing tubing of various specifications, including an adapter assembly and an interface assembly. The adapter assembly includes an adapter and a conductive wire. The input end of the adapter is provided with a plug, and the output end of the adapter is connected to one end of the conductive wire. The conductive wire includes a positive wire and a negative wire. The interface assembly includes a panel and multiple different breathing tubing interfaces provided on the panel. The other end of the conductive wire is disposed in the breathing tubing interface.

[0006] The adapter of this device converts the voltage from an external power source into the voltage required for the heating wire in the breathing tubing. The positive and negative terminals of the conductive wire are respectively located within the breathing tubing interface. Different breathing tubing interfaces are used to connect to connectors for different breathing tubing systems. The connectors for the breathing tubing have positive and negative leads for the heating wire. When a breathing tubing connector is connected to the device's breathing tubing interface, the positive and negative leads connect to the positive and negative terminals of the conductive wire, respectively, thus powering the heating wire. This device integrates multiple different breathing tubing interfaces onto a single panel, allowing it to connect to various breathing tubing systems for heating. This eliminates the need for multiple separate heating respirators, simplifying the testing process and improving efficiency.

[0007] Furthermore, there are multiple conductive wires connected in parallel.

[0008] The panel has multiple breathing tubing interfaces and multiple conductive wires connected in parallel, which can simultaneously supply power to multiple different breathing tubing interfaces, thereby heating multiple different breathing tubing.

[0009] Furthermore, a first circuit protection device is provided between the conductive wire and the output terminal of the adapter.

[0010] Adding a first circuit protection device to the adapter output can prevent damage to the adapter circuit from short circuits or heating wire overload. This first circuit protection device can be a self-resetting fuse with an operating current slightly higher than the heating wire's operating current.

[0011] Furthermore, each of the conductive lines is equipped with a second circuit protection device.

[0012] A second circuit protection device is installed on the positive electrode line of each conductive wire to prevent a short circuit in a single heating wire from affecting the power supply to other interfaces. The second circuit protection device can be a surface-mount fuse, selected according to the rated current of the interface.

[0013] Furthermore, the other end of the conductive wire is detachably disposed within the breathing tubing interface.

[0014] The panel integrates many breathing tubing interfaces, but the number of conductive wires may be less than the number of breathing tubing interfaces. The other end of the conductive wire is detachably installed inside the breathing tubing interface, making it easy to replace it with different breathing tubing interfaces.

[0015] Furthermore, the breathing tubing interface is provided with a connection hole, and the other end of the conductive wire is inserted into the connection hole.

[0016] The plug-in connection method makes connection and replacement simpler and more convenient. Specifically, the connection hole is a through hole. The conductive wire is inserted into the connection hole from the back of the panel, and the connection connector of the breathing tubing is connected to the breathing tubing interface from the front of the panel. After connection, the positive electrode lead and negative electrode lead of the heating wire are respectively inserted into the connection hole from the front of the panel and connected to the positive electrode lead and negative electrode lead of the conductive wire in the connection hole, thereby supplying power to the heating wire.

[0017] Furthermore, there are two connection holes, each marked with a positive and negative polarity indicator. The positive and negative polarity wires of the conductive wires are each a different color.

[0018] Positive and negative markings are set on the connection holes, and the positive and negative wires are distinguished by different colors. This is to prevent the positive and negative wires from being connected to the wrong connection holes, which would cause the positive and negative terminals of the heating wire to be reversed.

[0019] Furthermore, an indicator light is installed next to each breathing tubing interface.

[0020] An indicator light is installed next to the breathing tubing interface to show whether the heating wire is powered on or malfunctioning, to prevent situations where the connector is connected to the breathing tubing interface but the heating wire is not heating.

[0021] Furthermore, the interface component also includes a housing with an opening on one side, and the panel is disposed at the opening of the housing.

[0022] The panel has multiple through holes for fixing the breathing tubing interface. However, its thinness makes it difficult to place and move. Therefore, a box is provided to install the tubing, which makes it easier to place and move.

[0023] Furthermore, the panel is detachably disposed at the opening of the box.

[0024] After the panel is installed on the box, its back is inside the box. When it is necessary to replace the conductive wire to other breathing tubing interfaces, the panel needs to be removed. The panel is detachably set on the box, which makes it easy to replace the conductive wire to other breathing tubing. At the same time, it is also convenient to troubleshoot and repair when the device malfunctions.

[0025] Compared with existing technologies, the advantages of this invention are as follows: This device uses conductive wires at the output end of the adapter, with the ends of these wires positioned within different breathing tube interfaces fixed to the panel. When the connector of a breathing tube requiring heating is inserted into the breathing tube interface on the panel, the heating wire lead-out from the connector connects to the conductive wire within the breathing tube interface, thus supplying power to the heating wire and achieving the heating function. The ends of the conductive wires are detachably positioned within the breathing tube interfaces, allowing for selection of different interfaces as needed. Multiple parallel conductive wires can simultaneously heat multiple breathing tubes. A first circuit protection device is installed between the conductive wires and the adapter output end to prevent short circuits or heating wire overload from damaging the adapter. A second circuit protection device is installed on each conductive wire to prevent a short circuit in a single heating wire from affecting the power supply to other interfaces. The positive and negative wires of the conductive wires are colored differently, and positive and negative markings are provided on the connection holes of the breathing tube interfaces for easy identification, ensuring that the positive and negative wires are connected to their respective connection holes and preventing reverse connection of the heating wire's positive and negative terminals. Each breathing tubing interface is equipped with an indicator light to show whether the heating wire is powered or malfunctioning, preventing situations where the connector is connected to the breathing tubing interface but the heating wire is not heating. This device integrates multiple different breathing tubing interfaces onto a single panel, allowing it to connect to various breathing tubing types. Conductive wires leading from the adapter output are connected to each breathing tubing interface, enabling heating of different breathing tubing types. This eliminates the need for multiple separate heating ventilators for different breathing tubing types, simplifying the testing process and improving testing efficiency. Attached Figure Description

[0030] like Figure 1 , Figure 2 As shown, a device for heating breathing tubing of various specifications includes an adapter assembly 1 and an interface assembly 2. The adapter assembly 1 includes an adapter 11 and multiple conductive wires 12. The input end of the adapter 11 is provided with a plug 13, and the output end of the adapter 11 is provided with an output wire 14. A self-resetting fuse 141 is provided on the output wire 14 to prevent damage to the adapter circuit due to short circuit or overload of the heating wire. The multiple conductive wires 12 include a positive electrode 121 and a negative electrode 122, one end of which is connected to the output wire 14. The multiple conductive wires 12 are connected in parallel. The insulation layer of the positive electrode 121 and the negative electrode 122 is stripped to expose a section of metal wire. For easy distinction, the positive electrode 121 and the negative electrode 122 use different colored insulation layers. A surface-mount fuse 123 is also provided on each positive electrode 121 so that when a single heating wire is short-circuited, it will not affect the power supply to other interfaces.

[0031] like Figure 3 As shown, the interface assembly 2 includes a panel 21 and multiple breathing tubing interfaces 22 of different specifications disposed on the panel 21. The panel 21 has multiple through holes, and the multiple breathing tubing interfaces 22 of different specifications and shapes are fixed within these through holes. The breathing tubing interfaces 22 are made of high-temperature resistant plastic material. Each breathing tubing interface 22 has two connection holes 221. The other ends of the positive wire 121 and negative wire 122 of the conductive wire 12 are respectively inserted into the two connection holes 221. To prevent the positive wire 121 and negative wire 122 from being inserted into the wrong connection hole 221, identification marks are also provided next to the two connection holes 221. The connection holes 221 on each breathing tubing interface 22 are of the same size, so that the positive wire 121 and negative wire 122 can be inserted into the connection holes 221 on different interfaces 22. On some breathing tubing interfaces 22, in addition to two connection holes 221 for connecting the positive wire 121 and the negative wire 122, there are also holes for connecting the temperature sensor and the warning device.

[0032] An indicator light 23 is also provided next to each breathing tubing interface 22 to indicate whether the heating wire is powered on or malfunctioning, so as to avoid situations where the connector is connected to the breathing tubing interface 22 but the heating wire is not heating.

[0033] The interface assembly 2 also includes a housing 24 with an opening on one side. The panel 21 is detachably disposed at the opening of the housing 24. A switch 25 for controlling the on / off state of the control circuit is also provided on the housing 24.

[0034] The device also includes an intelligent control module and a temperature sensor. The temperature sensor monitors the temperature of the heating element in real time to ensure stable and safe heating. The intelligent control module includes a control unit and a display unit. The control unit receives signals from the temperature sensor and automatically adjusts the operating status of the heating element according to the preset heating temperature. The display unit shows information such as the current heating temperature and heating status, allowing users to easily understand the device's operating status.

[0035] like Figure 3 As shown, when using this device, select the appropriate breathing tubing interface 22 for the required heating connection. Insert the positive wire 121 and negative wire 122 of the conductive wire 12 into the connection hole 221 from the back of the panel 21. Then, insert the connecting connector of the breathing tubing to be heated into the breathing tubing interface 22 from the front of the panel 21. The connecting connector is equipped with the positive and negative leads of the heating wire. After insertion, the positive and negative leads of the heating wire are inserted into the two connection holes 221 respectively, connecting with the positive wire 121 and negative wire 122 of the conductive wire 12, thereby supplying power to the heating wire on the connecting connector and achieving heating. This device can also simultaneously insert the positive wires 121 and negative wires 122 of multiple conductive wires 12 into different breathing tubing interfaces 22 to heat multiple different breathing tubings at the same time. After the connecting connector is inserted into the breathing tubing interface 22, the indicator light 23 can be used to determine whether the heating wire is energized.
