Description

Technical Field

[0001] This utility model relates to the field of oxygen inhalation connection tube technology, specifically a double-connector connection tube for oxygen inhalation. Background Technology

[0002] In hospitals, oxygen therapy is a common treatment, primarily used to correct hypoxia and improve hypoxemia. Oxygen therapy can be administered in several ways, including mask oxygen therapy and nasal cannula oxygen therapy, each suitable for different clinical situations. Mask oxygen therapy provides more oxygen and is more suitable for patients with higher oxygen requirements, while nasal cannula oxygen therapy provides less oxygen and is more suitable for patients who do not require high concentrations of oxygen.

[0003] When choosing between mask oxygen therapy and nasal cannula oxygen therapy, medical staff will decide based on the patient's specific condition, oxygenation needs, and the patient's comfort and tolerance. Because patients' conditions often change, the method of oxygen therapy needs to be switched between these two methods. However, clinically, there is only one tube used to connect the oxygen cylinder to the mask or nasal cannula, as shown in the non-invasive ventilator mask oxygen connection tube in publication number CN204484983U. This means that one oxygen cylinder can only be connected to either a mask or nasal cannula. If additional oxygen therapy methods are needed, an additional oxygen cylinder must be added. Due to limited space at the head of the bed, there may not be enough space to place the additional oxygen cylinder, causing inconvenience.

[0004] In addition, existing connecting tubes for oxygen masks or nasal cannulas are installed by directly fitting them onto the oxygen cylinder outlet. To prevent leakage, the inner diameter of the connecting tube is set to be slightly larger than the oxygen cylinder outlet. Because the difference between the inner diameter of the connecting tube and the outer diameter of the oxygen cylinder outlet is small, medical staff often have to expend a lot of effort to install the connecting tube. In other words, the existing connecting tubes are difficult to install. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-connector tube for oxygen inhalation. By using a dual-connector to connect two extension tubes, the two extension tubes can be connected to an oxygen mask and a nasal cannula respectively, enabling the use of one oxygen cylinder to provide two different oxygen inhalation methods and improving the convenience of oxygen inhalation for patients.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a double-connector tube for oxygen inhalation, including an oxygen cylinder connector connected to an oxygen cylinder, the output port of the oxygen cylinder connector being connected to a double connector, the two output ports of the double connector being respectively connected to an extension tube, the end of the extension tube away from the double connector being provided with an oxygen inhalation connector, and the two oxygen inhalation connectors being respectively used to connect to a nasal cannula and an oxygen mask.

[0007] The oxygen cylinder connector includes a sealing and fixing assembly for fixing the position of the oxygen cylinder connector. The sealing and fixing assembly consists of two rigid tubes, an elastic membrane, an air bladder, and a movable limiting ring. The air bladder is filled with gas. By pushing the movable limiting ring downward, the air bladder is squeezed so that the elastic membrane is tightly attached to the outer wall of the oxygen cylinder outlet pipe, thereby sealing the gap between the oxygen cylinder connector and the oxygen cylinder outlet pipe and clamping the oxygen cylinder outlet pipe.

[0008] Preferably, the two rigid tubes are located on both sides of the elastic membrane, the rigid tubes are fixed to the elastic membrane, the airbag is fixed to the outer wall of the elastic membrane, and the airbag is located between the two rigid tubes.

[0009] Preferably, the movable limiting ring is sleeved on the outside of one of the rigid tubes, and the inner wall of the movable limiting ring near the airbag is processed into a bevel for downward squeezing the airbag;

[0010] The outer wall of the other end of the movable limiting ring is machined to protrude outwards, and the inner wall of the movable limiting ring at this end is machined with internal threads. The outer wall of the rigid tube that contacts the inner wall of the movable limiting ring is machined with external threads, and the movable limiting ring and the rigid tube are fixed together by the threads.

[0011] Preferably, both the elastic membrane and the airbag are made of thermoplastic polyurethane membrane material. Thermoplastic polyurethane membrane is a polymer material with excellent elasticity, wear resistance and chemical resistance. It has good oil resistance, water resistance, weather resistance and wear resistance. It also has high tensile strength and elongation, as well as good flexibility and impact resistance. The elastic membrane and airbag made of this material not only have good elasticity but also a certain strength, ensuring that they can deform under compression and stick tightly to the outer wall of the oxygen tank outlet pipe.

[0012] Preferably, the oxygen cylinder connector further includes connector tube a and connector tube b. One end of connector tube a is fixed to the end of one of the rigid tubes away from the elastic membrane, one end of connector tube b is fixed to the end of another rigid tube away from the elastic membrane, and the other end of connector tube b is fixedly connected to the air inlet of the double connector.

[0013] Preferably, a sealing ring is fixed to the inner wall of one end of the connector tube a.

[0014] Preferably, both extension tubes are equipped with Robert clamps at their outer ends to prevent oxygen flow.

[0015] Compared with the prior art, this utility model provides a double-connector tube for oxygen inhalation, which has the following beneficial effects:

[0016] 1. By using a double connector to connect two extension tubes, the two extension tubes can be connected to an oxygen mask and a nasal cannula respectively, so that one oxygen cylinder can provide two different oxygen inhalation methods. This can meet the needs of the same patient for different concentrations of oxygen under different conditions and improve the convenience of oxygen inhalation for patients.

[0017] 2. By using the movable limiting ring to squeeze the internally inflated airbag downwards, the airbag can squeeze the elastic membrane downwards to make it tightly adhere to the outer wall of the oxygen cylinder outlet pipe. On the one hand, the compression of the airbag and the elastic membrane can fix the oxygen cylinder connector to the outside of the oxygen cylinder outlet pipe, reducing the difficulty of installation of this utility model. On the other hand, the downward-squeezed airbag and elastic membrane can block and seal the gap between the inner wall of the oxygen cylinder connector and the outer wall of the oxygen cylinder outlet pipe, improving the sealing performance of the connection between this utility model and the oxygen cylinder.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5As shown, this utility model provides a dual-connector tube for oxygen inhalation, including an oxygen cylinder connector 1 connected to an oxygen cylinder. The output port of the oxygen cylinder connector 1 is connected to a dual connector 2. The two output ports of the dual connector 2 are respectively connected to an extension tube 3. An oxygen inhalation connector 4 is provided at the end of the extension tube 3 away from the dual connector 2. The two oxygen inhalation connectors 4 are respectively used to connect to a nasal cannula and an oxygen mask. This utility model, through the setting of two extension tubes 3, can connect an oxygen mask and a nasal cannula to one oxygen cylinder at the same time, providing two different oxygen inhalation methods to meet the needs of patients for different concentrations of oxygen and improve the convenience of clinical use of this utility model.

[0029] When using, shut off the oxygen supply inside one of the extension tubes 3, allowing oxygen to flow out through the oxygen mask or nasal cannula connected to the other extension tube 3. To prevent the flow of oxygen from the other extension tube 3, such as... Figure 1 and 2 As shown, both extension tubes 3 are equipped with Robert clamps 5 at their outer ends to block the flow of oxygen. For extension tubes 3 where it is necessary to block the flow of oxygen, medical staff can simply clamp the Robert clamps 5 with their hands to block the flow of oxygen. Conversely, by loosening the Robert clamps 5, oxygen can flow smoothly inside the extension tubes 3.

[0030] In addition, to facilitate the installation of this utility model on the oxygen cylinder outlet pipe, such as Figure 2-5 As shown, the oxygen cylinder connector 1 of this utility model includes a connector tube a11 and a connector tube b12. A sealing ring 14 is fixed to the inner wall of one end of the connector tube a11. The connector tube a11 is used to fit over the outside of the oxygen cylinder outlet pipe, and the connector tube b12 is fixedly connected to the double connector 2. Figure 4 and 5 As shown;

[0031] The oxygen cylinder connector 1 of this utility model also includes a sealing and fixing component 13 for fixing the position of the oxygen cylinder connector 1. The sealing and fixing component 13 consists of two rigid tubes 131, an elastic membrane 132, an air bladder 133 and a movable limiting ring 134. One end of the connector tube a11 is fixed to the end of one of the rigid tubes 131 away from the elastic membrane 132, and one end of the connector tube b12 is fixed to the end of the other rigid tube 131 away from the elastic membrane 132.

[0032] Both the elastic membrane 132 and the airbag 133 are made of thermoplastic polyurethane membrane material. This material gives both the elastic membrane 132 and the airbag 133 high elasticity and strength, allowing them to deform but not easily break. Two rigid tubes 131 are located on both sides of the elastic membrane 132 and are fixed to the elastic membrane 132. The airbag 133 is fixed to the outer wall of the elastic membrane 132 and is located between the two rigid tubes 131. The airbag 133 is filled with gas and protrudes outwards. Figure 4 As shown, the movable limiting ring 134 is sleeved on the outside of one of the rigid tubes 131, and the inner wall of the movable limiting ring 134 near the airbag 133 is processed into a bevel, which fits against the outer wall of the airbag 133. The outer wall of the other end of the movable limiting ring 134 is processed into an outward protrusion.

[0033] When connecting this utility model to the oxygen cylinder outlet pipe, firstly, the connector pipe a11 must be fitted over the outside of the oxygen cylinder outlet pipe, such as... Figure 5 As shown, because the inner diameter of the connector tube a11 is larger than the outer diameter of the oxygen cylinder outlet tube, medical staff can easily put the connector tube a11 onto the outer wall of the oxygen cylinder outlet tube and then push the moving limiting ring 134 toward the oxygen cylinder. During this process, the inclined surface of the port of the moving limiting ring 134 will squeeze the protruding air bag 133 downward, and at the same time, the air bag 133 will squeeze the elastic membrane 132 downward, so that the elastic membrane 132 is tightly attached to the outer wall of the oxygen cylinder outlet tube. At this time, under the squeezing action of the air bag 133, the oxygen cylinder outlet tube can be tightly clamped inside the oxygen cylinder connector 1, achieving a fixing effect. At the same time, the protruding air bag 133 and the elastic membrane 132 can also seal the gap between the oxygen cylinder connector 1 and the outer wall of the oxygen cylinder outlet tube, achieving a sealing effect to prevent oxygen leakage.

[0034] In order to ensure that the airbag 133 and the elastic membrane 132 can maintain their respective properties... Figure 5 The downward convex state shown requires fixing the position of the movable limiting ring 134. In this invention, an internal thread is machined on the inner wall of the outward convex end of the movable limiting ring 134, and an external thread is machined on the outer wall of the rigid tube 131 that contacts the inner wall of the movable limiting ring 134. Therefore, after the movable limiting ring 134 compresses the airbag 133 and convexes downward, the movable limiting ring 134 can be rotated. The movable limiting ring 134 and the rigid tube 131 are fixed together by the connection between the internal thread on the inner wall of the movable limiting ring 134 and the external thread on the outer wall of the rigid tube 131, so as to fix the position of the movable limiting ring 134.

[0035] This invention utilizes the downward protrusion of the compression airbag 133 to install the oxygen cylinder connector 1 on the outlet pipe of oxygen cylinders with different outer diameters. This method not only reduces the operational difficulty for medical personnel during installation but also expands the scope of application of this invention, achieving two goals at once.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
