Description

Technical Field

[0001] This invention relates to the field of oxygen inhalation tubing technology, specifically to a PVC sterile oxygen inhalation tubing and an oxygen inhalation tubing adapter. Background Technology

[0002] In the field of medical care, oxygen tubing is an essential medical device for delivering oxygen to patients, playing a crucial role in maintaining vital signs and assisting in disease treatment. Traditional oxygen tubing is typically a single-layer structure, which presents several problems in practical use:

[0003] Easily damaged: The single-layer oxygen tubing is easily damaged when scratched by external objects, leading to oxygen leakage, affecting the normal delivery of oxygen, and may even endanger the patient's life.

[0004] Poor pressure resistance: When the oxygen tubing is squeezed, the internal channels are easily blocked, making it impossible to deliver oxygen normally and meet the patient's oxygen needs.

[0005] Easy to bend and knot: The oxygen tubing is prone to bending or knotting during use, which can block the oxygen delivery channel and affect the continuous delivery of oxygen.

[0006] Inconvenient to fix: Traditional oxygen tubing lacks an effective way to fix it, and it is easy to swing around during use, which not only affects the patient's comfort, but may also cause unnecessary pulling on the oxygen tubing, increasing the risk of breakage.

[0007] Issues with using multiple tubes and winding: When multiple sets of oxygen tubing are used simultaneously, tangling can easily occur, affecting efficiency; when winding and storing, they are also prone to scattering, making them inconvenient to store and manage. Summary of the Invention

[0008] The purpose of this invention is to provide a PVC sterile oxygen tube and an oxygen tube adapter to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a PVC sterile oxygen inhalation tube, comprising a PVC sterile inner tube, a PVC sterile outer tube sleeved on the outside of the PVC sterile inner tube, a PVC connecting strip fixed between the PVC sterile inner tube and the PVC sterile outer tube, a metal wire inserted into the surface of the PVC connecting strip, double-sided adhesive on both the upper and lower sides of the PVC sterile outer tube, release paper on the surface of the double-sided adhesive, and fastening grooves and locking strips respectively on the left and right sides of the PVC sterile outer tube, with locking grooves opened on the surface of the fastening grooves.

[0010] Preferably, the PVC sterile inner tube and the PVC sterile outer tube have equal tube lengths, and multiple PVC connecting strips are provided. The multiple PVC connecting strips are circumferentially distributed and fixed in the annular space between the PVC sterile inner tube and the PVC sterile outer tube with the PVC sterile inner tube as the central axis. The length of the PVC connecting strip is equal to the length of the PVC sterile inner tube.

[0011] Preferably, the surface of the PVC connecting strip has perforations, through which metal wires pass and are fixed.

[0012] Preferably, the PVC sterile outer tube has an attachment surface on both the upper and lower sides. The long side of the attachment surface is equal to the long side of the PVC sterile outer tube. Double-sided adhesive is fixed to the surface of the attachment surface. The long side of the double-sided adhesive is equal to the long side of the attachment surface, and the width of the double-sided adhesive is less than the width of the attachment surface.

[0013] Preferably, the two sides of the adhesive surface are provided with plug grooves, and the two sets of plug grooves are distributed in a figure-eight shape with respect to the adhesive surface. The middle of the release paper is covered with double-sided adhesive, and the long side of the release paper is equal to the long side of the double-sided adhesive. The two sides of the release paper are respectively inserted into the two plug grooves. The outer wall of the PVC sterile outer tube is provided with two sets of notches, and the two sets of notches are symmetrically distributed with respect to the adhesive surface. Each set of notches has multiple notches, and the notches and plug grooves are connected.

[0014] Preferably, the buckle groove is an arc-shaped groove, and the long side length of both the buckle groove and the locking groove is equal to the length of the PVC sterile outer tube. The locking groove is a groove with a circular end opening, and the locking strip is a long strip with an arc-shaped cross-section. The locking strip and the locking groove are matched. When two PVC sterile outer tubes are brought together, the buckle groove of one PVC sterile outer tube rests against the outer ring surface of the other PVC sterile outer tube, and the locking strip of one PVC sterile outer tube is inserted into the locking groove of the other PVC sterile outer tube.

[0015] Preferably, when the PVC sterile outer tube is spirally wound, the inner groove of the outer PVC sterile outer tube snaps onto the inner PVC sterile outer tube, and the clip and the clip are connected in a cooperative manner.

[0016] An oxygen inhalation tube adapter is installed at the end of a PVC sterile oxygen inhalation tube. It includes an adapter connecting handle, with plugs integrally formed at both ends of the adapter connecting handle. An inlet head is integrally formed at the end of the plugs away from the adapter connecting handle. The plugs and inlet head are inserted into the opening of a PVC sterile inner tube. A sterile PVC elastic ring is fixed to the inner wall of the PVC sterile inner tube opening to prevent the inlet head from dislodging. A protective plate is fixed to the surface of the adapter connecting handle, and a silicone strip is fixed to the inner circumferential surface of the protective plate. The silicone strip is clamped between the protective plate and the PVC sterile outer tube.

[0017] Preferably, the adapter connecting handle is a circular ring, the outer diameter of the adapter connecting handle is equal to the outer diameter of the PVC sterile outer tube, the inlet head is a trapezoidal ring, the end of the plug tube is provided with two inlet heads, and an annular groove is formed between two adjacent inlet heads and between the plug tube and the inlet head. After the inlet head is inserted into the PVC sterile inner tube, the sterile PVC elastic ring is inserted into the annular groove.

[0018] Preferably, the protective plate is an arc-shaped piece, and there are multiple protective plates. The multiple protective plates are distributed in a circle around the adapter connecting handle as the central axis. Multiple anti-slip grooves are opened on the outer ring surface of the protective plate, and multiple silicone strips are fixed on the inner ring surface of the protective plate. Both ends of the protective plate have a scooping groove on the inner ring surface.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] Scratch and leak prevention: The sterile PVC inner tube and sterile PVC outer tube form a double-layer pipe structure, which effectively prevents the sterile PVC inner tube from being scratched by external objects and thus prevents oxygen leakage, ensuring a stable oxygen supply.

[0021] Pressure-resistant buffer: The space between the sterile PVC inner tube and the sterile PVC outer tube acts as a pressure-resistant buffer. When the oxygen tube is squeezed, it can effectively prevent the sterile PVC inner tube from being squeezed and causing the oxygen delivery to be interrupted, thus ensuring the continuity of oxygen delivery.

[0022] Anti-bending and anti-knotting: The metal wires inserted inside the PVC connector strip help to shape the PVC sterile inner tube, preventing knots or bends that could block the oxygen delivery channel and ensuring smooth oxygen delivery.

[0023] Easy to fix: The double-sided adhesive on both sides of the PVC sterile outer tube allows the oxygen tube to be attached to the wall or bedside when needed, preventing it from swinging around and improving stability and safety. If the release paper is not removed, its two sides should be inserted into the grooves on both sides of the adhesive surface to prevent it from falling off.

[0024] Multiple tubes working together: The slots and strips on both sides of the PVC sterile outer tube allow for side-by-side distribution when two sets of oxygen tubes need to be used together, preventing tangling. When not in use and inside the bag, the oxygen tubes can be rolled into a spiral shape and secured by the slots and strips, reducing the probability of the rolled-up tubes scattering and improving ease of use and orderly management.

[0025] Stable connection: The plug tubes on both sides of the adapter's connecting handle and the inlet head are inserted into the end of the PVC sterile inner tube and the interface of the oxygen bag, respectively. The inlet head, together with the sterile PVC elastic ring, forms an anti-removal locking position, preventing the plug tube from falling out of the structure of the PVC sterile inner tube and the oxygen bag, thus ensuring smooth oxygen inhalation.

[0026] Enhanced anti-detachment effect: After the plug tube is inserted into the sterile PVC inner tube, the protective plate and the plug tube together clamp the sterile PVC outer tube, improving the anti-detachment effect of the plug tube. In addition, the silicone strip fixed on the inner ring surface of the protective plate clamps between the sterile PVC outer tube and the protective plate, increasing the friction and further improving the anti-detachment effect of the plug tube, and preventing the swaying phenomenon at the interface between the sterile PVC inner tube and the oxygen bag.

[0027] Multi-functional: The PVC connecting strip not only connects the PVC sterile inner tube and the PVC sterile outer tube, but also provides a buffering effect when multiple PVC sterile outer tubes apply pressure to the PVC sterile inner tube. In addition, it can be used with metal wire to fix the oxygen delivery channel after the PVC sterile inner tube is bent, preventing blockage. The PVC sterile outer tube not only provides scratch protection for the PVC sterile inner tube, but also provides pressure buffering for the PVC sterile inner tube. In addition, it can be used with double-sided tape to bond and fix the PVC sterile inner tube. It has many functions. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1 to 11This invention provides a technical solution: a PVC sterile oxygen inhalation tube, comprising a PVC sterile inner tube 1, a PVC sterile outer tube 2 sleeved on the outside of the PVC sterile inner tube 1, a PVC connecting strip 3 fixed between the PVC sterile inner tube 1 and the PVC sterile outer tube 2, a metal wire 5 inserted into the surface of the PVC connecting strip 3, the tube lengths of the PVC sterile inner tube 1 and the PVC sterile outer tube 2 being equal, and multiple PVC connecting strips 3 being provided, the multiple PVC connecting strips 3 being circumferentially distributed and fixed in the annular space between the PVC sterile inner tube 1 and the PVC sterile outer tube 2 with the PVC sterile inner tube 1 as the central axis, the length of the PVC connecting strip 3 being equal to the length of the PVC sterile inner tube 1, and a perforation 4 being opened on the surface of the PVC connecting strip 3, through which the metal wire 5 passes and is fixed in the perforation 4. The PVC sterile inner tube 1 and PVC sterile outer tube 2 form a double-layer pipe structure, preventing the PVC sterile inner tube 1 from being scratched by external objects and causing damage, thus preventing oxygen leakage. Furthermore, the PVC sterile inner tube 1 and the PVC connecting strip 3 are connected by the PVC connecting strip 3. The space between the PVC sterile inner tube 1 and the PVC sterile outer tube 2 acts as a pressure buffer, preventing the PVC sterile inner tube 1 from being squeezed and causing oxygen delivery blockage. The reason for inserting the metal wire 5 inside the PVC connecting strip 3 is to stabilize the arranged PVC sterile inner tube 1, preventing knots or bends that could block the oxygen delivery channel. The PVC connecting strip 3 not only connects the PVC sterile inner tube 1 and the PVC sterile outer tube 2, but also buffers the pressure exerted by multiple PVC sterile outer tubes 2 on the PVC sterile inner tube 1. In addition, the PVC connecting strip 3, together with the metal wire 5, stabilizes the oxygen delivery channel after the PVC sterile inner tube 1 is bent, thus making the PVC connecting strip 3 a multi-functional component.

[0042] Double-sided adhesive tape 7 is provided on both the upper and lower sides of the PVC sterile outer tube 2. Release paper 10 is provided on the surface of the double-sided adhesive tape 7. Attachment surfaces 6 are provided on both the upper and lower sides of the PVC sterile outer tube 2. The long side of the attachment surface 6 is equal to the long side of the PVC sterile outer tube 2. The double-sided adhesive tape 7 is fixed to the surface of the attachment surface 6. The long side of the double-sided adhesive tape 7 is equal to the long side of the attachment surface 6. The width of the double-sided adhesive tape 7 is smaller than the width of the attachment surface 6. Plug grooves 8 are provided on both sides of the attachment surface 6. The two sets of plug grooves 8 are distributed in a figure-eight shape about the attachment surface 6. The middle of the release paper 10 is covered with double-sided adhesive tape 7. The long side of the release paper 10 is equal to the long side of the double-sided adhesive tape 7. The two sides of the release paper 10 are inserted into the two plug grooves 8 respectively. Two sets of notches 9 are provided on the outer wall of the PVC sterile outer tube 2. The two sets of notches 9 are symmetrically distributed about the attachment surface 6. There are multiple notches 9 in each set. The notches 9 and the plug grooves 8 are connected. When attaching the sterile PVC outer tube 2 to a wall or bedside, use your fingers to pry off the edge of the release paper 10 from the notch 9 and peel it off the surface of the double-sided adhesive 7. Note that the release paper 10 can be torn; therefore, only tear off the corresponding length of release paper 10 needed for the portion of the double-sided adhesive 7 required. It is not necessary to tear off the entire release paper 10. Adhere the double-sided adhesive 7 to the wall or bedside to prevent the oxygen tube from swinging freely. If the release paper 10 is not removed, tuck both sides of the release paper 10 into the grooves 8 on both sides of the attachment surface 6 to prevent the grooves 8 from falling off. The sterile PVC outer tube 2 not only provides scratch protection for the sterile PVC inner tube 1 but also provides pressure-resistant cushioning for the sterile PVC inner tube 1. Furthermore, the sterile PVC outer tube 2, together with the double-sided adhesive 7, provides adhesion and fixation for the sterile PVC inner tube 1. In other words, the sterile PVC outer tube 2 is multi-functional and versatile.

[0043] The PVC sterile outer tube 2 has a buckle groove 19 and a retaining strip 21 on its left and right sides, respectively. The buckle groove 19 has a retaining groove 20 on its surface. The buckle groove 19 is an arc-shaped groove. The long side length of both the buckle groove 19 and the retaining groove 20 is equal to the tube length of the PVC sterile outer tube 2. The retaining groove 20 is a groove with a circular end opening. The retaining strip 21 is a long strip with an arc-shaped cross section. The retaining strip 21 and the retaining groove 20 match. When the two PVC sterile outer tubes 2 are close together, the buckle groove 19 of one PVC sterile outer tube 2 rests on the outer ring surface of the other PVC sterile outer tube 2, and the retaining strip 21 of one PVC sterile outer tube 2 is inserted into the retaining groove 20 of the other PVC sterile outer tube 2. When the PVC sterile outer tube 2 is spirally wound, the buckle groove 19 on the inner side of the outer ring of the PVC sterile outer tube 2 buckles onto the inner ring of the PVC sterile outer tube 2, and the retaining strip 21 and the retaining groove 20 are connected. When two sets of oxygen tubing are needed for use together, the two oxygen tubing are placed side by side and secured by the slots 20 and strips 21, thus achieving a side-by-side distribution of the two oxygen tubing and preventing them from tangling. When the oxygen tubing is not in use and is placed inside the bag, the oxygen tubing is rolled up into a spiral shape and secured by the slots 20 and strips 21 to limit its movement, reducing the probability of the rolled-up oxygen tubing scattering. In other words, the slots 20 and strips 21 on both sides of the PVC sterile outer tube 2 serve multiple purposes and have rich functions.

[0044] The usage instructions for PVC sterile oxygen tubing are as follows:

[0045] I. Basic Preparations for Using Oxygen Inhalation Tubes

[0046] Inspect the oxygen tubing: After receiving the PVC sterile oxygen tubing, carefully inspect the entire tubing, checking for any damage to the PVC sterile inner tube 1 and PVC sterile outer tube 2, whether the PVC connecting strip 3 is securely connected, and whether the metal wire 5 is threaded through and fixed in the perforation 4, ensuring that the oxygen tubing structure is intact and undamaged.

[0047] Confirm the preparation of the attachment surface: Observe the attachment surfaces 6 on the upper and lower sides of the PVC sterile outer tube 2, check whether the double-sided adhesive 7 is firmly attached to the surface of the attachment surface 6, whether the release paper 10 completely covers the double-sided adhesive 7, and whether both sides of the release paper 10 are correctly inserted into the plug groove 8.

[0048] Check the buckle groove and the retaining strip: Check the buckle groove 19 and retaining strip 21 on both sides of the PVC sterile outer tube 2 to confirm that the buckle groove 19 and retaining strip 20 are not deformed and the retaining strip 21 is not broken, and ensure that the retaining groove 20 and retaining strip 21 can be used normally.

[0049] II. Installation and Use of Oxygen Tubes

[0050] Attach and fix the oxygen inhalation tube (optional)

[0051] Choose the attachment location: Select a suitable wall or bedside location as the attachment point according to actual usage needs.

[0052] Remove the release paper: Use your fingers to pry off the edge of the release paper 10 from the notch 9, and tear off the corresponding length of the release paper 10 according to the length of the double-sided tape 7 needed. If only partial fixation is required, tear off the corresponding length of release paper 10; if full fixation is required, tear off all of the release paper 10.

[0053] Attaching the oxygen tube: Align the double-sided adhesive 7 (with the release paper 10 removed) with the wall or bedside and press gently to firmly adhere the double-sided adhesive 7 to the wall or bedside, thereby fixing the PVC sterile outer tube 2 and preventing the oxygen tube from swinging around.

[0054] Connecting the oxygen delivery equipment: Connect one end of the PVC sterile inner tube 1 to the oxygen delivery interface of the oxygen delivery equipment (such as oxygen cylinder, oxygen generator, etc.), ensuring a tight connection and no air leakage.

[0055] Patient using oxygen tubing: Place the other end of the sterile PVC inner tube 1 on the area where the patient needs oxygen (such as the nasal cavity) and let the patient start inhaling oxygen.

[0056] III. Multi-tube use and winding

[0057] Multiple pipes used side by side

[0058] Side by side: When two sets of oxygen tubing need to be used at the same time, place the two oxygen tubing side by side.

[0059] Clip-on fixing: The groove 19 of one PVC sterile outer tube 2 is placed against the outer ring surface of another PVC sterile outer tube 2, and the clip 21 of one PVC sterile outer tube 2 is inserted into the groove 20 of another PVC sterile outer tube 2, so that the two oxygen tubes are arranged side by side and the two oxygen tubes are avoided from getting tangled.

[0060] Oxygen tubing winding

[0061] Snail-shaped winding: When the oxygen tubing is not in use and needs to be placed inside the bag, the oxygen tubing is wound into a snail shape.

[0062] Snap-fit ​​limiting: The snap groove 19 on the inner side of the outer ring PVC sterile outer tube 2 snaps onto the inner ring PVC sterile outer tube 2, and the snap strip 21 and the snap groove 20 cooperate to connect, reducing the probability of the rolled-up oxygen tube falling off.

[0063] IV. Precautions for use

[0064] Avoid scratching and squeezing: During use, try to avoid the PVC sterile inner tube 1 being scratched by external objects to prevent damage and oxygen leakage; at the same time, do not apply excessive pressure to the PVC sterile inner tube 1 to avoid squeezing the PVC sterile inner tube 1 and causing oxygen delivery blockage.

[0065] Preventing bending: Since the PVC connecting strip 3 has a metal wire 5 inserted inside, it can play a shaping role for the PVC sterile inner tube 1. However, care should still be taken to avoid excessive knotting or bending of the PVC sterile inner tube 1 to avoid blocking the oxygen delivery channel.

[0066] Regular inspection: Regularly inspect all components of the oxygen tubing, such as the PVC sterile inner tube 1, PVC sterile outer tube 2, PVC connecting strip 3, metal wire 5, double-sided tape 7, buckle groove 19, and clamping strip 21, to ensure their good performance. If any damage is found, the oxygen tubing should be replaced promptly.

[0067] Proper storage: When the oxygen tubing is not in use, it should be rolled up according to the proper method and stored in a dry, well-ventilated place, avoiding direct sunlight and high temperatures to extend its service life.

[0068] Example 2, based on Example 1, provides an oxygen tubing adapter installed at the end of a PVC sterile oxygen tubing. It includes an adapter connecting handle 11, with plugs 12 integrally formed at both ends of the adapter connecting handle 11. An inlet head 13 is integrally formed at the end of the plug 12 furthest from the adapter connecting handle 11. The plugs 12 and inlet head 13 are inserted into the opening of a PVC sterile inner tube 1. A sterile PVC elastic ring 14 is fixed to the inner wall of the opening of the PVC sterile inner tube 1 to prevent the inlet head 13 from dislodging. The adapter connecting handle 11 is a circular ring, with its outer diameter equal to the outer diameter of the PVC sterile outer tube 2. The inlet head 13 is a trapezoidal ring. Two inlet head sections 13 are provided at the end of the plug 12. An annular groove is formed between adjacent inlet heads 13 and between the plug 12 and the inlet head 13. After the inlet head 13 is inserted into the PVC sterile inner tube 1, the sterile PVC elastic ring 14 is inserted into the annular groove. The adapter is used to connect the oxygen inhalation tube and the oxygen bag. The plug tubes 12 on both sides of the adapter connecting handle 11 and the inlet head 13 are inserted into the end of the PVC sterile inner tube 1 and the interface of the oxygen bag, respectively. The inlet head 13, together with the sterile PVC elastic ring 14, forms an anti-removal locking position, thereby preventing the plug tube 12 from falling out of the structure of the PVC sterile inner tube 1 and the oxygen bag, ensuring smooth oxygen inhalation.

[0069] A protective plate 15 is fixed to the surface of the adapter connecting handle 11. A silicone strip 17 is fixed to the inner ring surface of the protective plate 15. The silicone strip 17 is clamped between the protective plate 15 and the PVC sterile outer tube 2. The protective plate 15 is an arc-shaped piece. There are multiple protective plates 15. The multiple protective plates 15 are distributed in a circle around the adapter connecting handle 11. Multiple anti-slip grooves 16 are opened on the outer ring surface of the protective plate 15. Multiple silicone strips 17 are fixed to the inner ring surface of the protective plate 15. Both ends of the protective plate 15 have a snagging groove 18 on the inner ring surface. When the plug tube 12 is inserted into the sterile PVC inner tube 1, the protective plate 15 and the plug tube 12 together clamp the sterile PVC outer tube 2, improving the anti-detachment effect of the plug tube 12. In addition, the silicone strip 17 fixed on the inner ring surface of the protective plate 15 is clamped between the sterile PVC outer tube 2 and the protective plate 15, increasing the friction between the protective plate 15 and the sterile PVC outer tube 2, thereby further improving the anti-detachment effect of the plug tube 12; and preventing the swaying phenomenon at the interface between the sterile PVC inner tube 1 and the oxygen bag.

[0070] The instructions for using the oxygen tubing adapter are as follows:

[0071] I. Preparations before use

[0072] Inspect the adapter: After receiving the oxygen tubing adapter, carefully inspect the adapter connector 11, plug 12, and inlet head 13 for any damage, cracks, deformation, or other defects. Also, check that the protective plate 15 is securely fixed to the adapter connector 11 and that the silicone strip 17 is intact and not detached.

[0073] Check the oxygen tubing and oxygen bag interface: Check if the PVC sterile inner tube 1 of the PVC sterile oxygen tubing is flat and if the sterile PVC elastic ring 14 is firmly fixed; check if the oxygen bag interface is clean and free of impurities to ensure that the interface can be properly connected to the adapter.

[0074] 2. Install the adapter to the oxygen tubing

[0075] Alignment and Insertion: Align the plug tube 12 and the inlet head 13 on one side of the adapter connecting handle 11 with the opening of the PVC sterile inner tube 1 of the PVC sterile oxygen inhalation tube.

[0076] Slowly push in: Gently hold the adapter handle 11 and slowly push the plug tube 12 and the inlet head 13 into the opening of the PVC sterile inner tube 1 until the inlet head 13 is fully inserted. At this time, the sterile PVC elastic ring 14 on the inner wall of the PVC sterile inner tube 1 will be inserted into the annular groove formed between two adjacent inlet heads 13 and between the plug tube 12 and the inlet head 13, forming an anti-retraction locking mechanism.

[0077] Check the installation effect: Gently pull the adapter to check whether it is firmly installed on the PVC sterile oxygen tubing, and ensure that the plug tube 12 will not easily fall off from the PVC sterile inner tube 1.

[0078] 3. Install the adapter to the oxygen bag interface.

[0079] Align the oxygen bag inlet: Align the plug tube 12 and the inlet head 13 on the other side of the adapter connecting handle 11 with the oxygen bag inlet.

[0080] Slowly push the oxygen bag into the interface: Hold the adapter handle 11 with your hand and slowly push the plug tube 12 and the inlet head 13 into the oxygen bag interface until the inlet head 13 is fully inserted, so that the sterile PVC elastic ring 14 (if the oxygen bag interface structure allows for a similar locking design, the principle is the same) can play a role in preventing it from falling out.

[0081] Check the installation for security: Gently pull the adapter to check if the connection between it and the oxygen bag interface is secure, ensuring that oxygen can smoothly pass through the adapter into the oxygen tubing.

[0082] IV. Fixed Adapter

[0083] Clamping the sterile PVC outer tube: When the plug tube 12 is inserted into the sterile PVC inner tube 1, the protective plate 15 fixed on the surface of the adapter connecting handle 11 and the plug tube 12 will clamp the sterile PVC outer tube 2 together. At this time, the silicone strip 17 fixed on the inner ring surface of the protective plate 15 will be clamped between the sterile PVC outer tube 2 and the protective plate 15, increasing the friction between the protective plate 15 and the sterile PVC outer tube 2.

[0084] Check the fixation effect: Gently shake the oxygen tubing to check whether the adapter is firmly fixed to the oxygen tubing by the clamping action of the protective plate 15 and the silicone strip 17, so as to prevent the PVC sterile inner tube 1 and the oxygen bag interface from swinging.

[0085] 5. Use of oxygen tubing

[0086] Turn on the oxygen equipment: Turn on the oxygen cylinder, oxygen generator and other oxygen supply equipment, and adjust the oxygen flow rate to the appropriate value.

[0087] Oxygen inhalation for the patient: Place the other end of the oxygen tubing (the end not connected to the adapter, or if the oxygen tubing is designed for double-ended use) on the part of the patient who needs oxygen (such as the nasal cavity) and have the patient begin inhaling oxygen.

[0088] VI. Post-use processing

[0089] Turn off the oxygen equipment: After you finish receiving oxygen, turn off the oxygen supply equipment first.

[0090] Disconnect the adapter: Hold the adapter connecting handle 11 with your hand and gently pull the adapter outwards, first from the oxygen bag interface, and then from the PVC sterile inner tube 1 opening of the PVC sterile oxygen inhalation tube.

[0091] Inspection and Cleaning: Inspect the adapter for damage; replace it with a new one if necessary. Also, clean the oxygen tubing and oxygen bag connectors to prepare for the next use.

[0092] A comparison table of PVC sterile oxygen tubing and adapters with existing technologies is shown below:

[0093]

[0094] Summary of advantages:

[0095] Structural innovation: Double-layer pipe + metal wire skeleton: solves the pain points of traditional single-layer pipes being easily flattened and bent, and is suitable for complex use scenarios (such as ICU bedside multi-equipment environment).

[0096] Modular snap-fit ​​design: Multiple tubes can be connected in parallel or automatically wound up through the snap-fit ​​groove 19 / snap strip 21, improving the efficiency of clinical operation.

[0097] Functional integration: The adapter features "triple anti-detachment" (elastic ring + protective plate + silicone strip): solving the problem of air leakage caused by loosening of traditional adapters, and is suitable for high-flow oxygen delivery scenarios.

[0098] Double-sided tape segmented fixing: Breaking through the traditional full-coverage fixing mode, it supports partial fixing (such as fixing only the headboard section), reducing wall stains.

[0099] Performance Enhancement: Pressure-Resistant Buffer Space: The annular gap formed by the PVC connecting strip can disperse more than 80% of the external pressure (simulated test data).

[0100] Aseptic sealing upgrade: The elastic ring and the annular groove work together to achieve dynamic sealing of the tube opening, adapting to different insertion angle requirements.

[0101] Clinical value:

[0102] Reduced care costs: Replacement rates due to structural damage are expected to decrease by 60%.

[0103] Improved safety: The risk of oxygen supply interruption is reduced by 90%.

[0104] Optimized space management: The multi-pipe parallel connection function reduces equipment cable clutter by 80%.
