Description

Technical Field

[0001] The present invention relates to the technical field of oxygen inhalation tubes, and particularly to a PVC sterile oxygen inhalation tube and an oxygen inhalation tube adapter. Background Art

[0002] In the field of medical care, oxygen inhalation tubes are important medical devices for delivering oxygen to patients, and play a crucial role in maintaining the vital signs of patients and assisting in the treatment of diseases. Traditional oxygen inhalation tubes are usually of a single-layer structure, and there are many problems in actual use:

[0003] Easy to break: When the single-layer oxygen inhalation tube is scratched by external objects, it is easy to break, resulting in oxygen leakage during oxygen delivery, affecting the normal delivery of oxygen, and even endangering the life safety of patients.

[0004] Poor compressive resistance: When the oxygen inhalation tube is squeezed, the internal channel is easily blocked, making it impossible to deliver oxygen normally and unable to meet the oxygen inhalation needs of patients.

[0005] Easy to bend and knot: The oxygen inhalation tube is prone to bending or knotting during use, causing the oxygen delivery channel to be blocked and affecting the continuous delivery of oxygen.

[0006] Inconvenient to fix: Traditional oxygen inhalation tubes lack effective fixing methods and are prone to swing randomly during use, which not only affects the comfort of patients, but also may cause the oxygen inhalation tube to be pulled unnecessarily, increasing the risk of breakage.

[0007] Problems of multi-tube use and winding: When multiple groups of oxygen inhalation tubes need to be used simultaneously, entanglement is likely to occur, affecting the use efficiency; when winding and storing, they are also prone to scattering, which is not convenient for storage and management. Summary of the Invention

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

[0009] To achieve the above purpose, the present invention provides the following technical solution: A PVC sterile oxygen inhalation tube includes a PVC sterile inner tube, a PVC sterile outer tube is sleeved outside the PVC sterile inner tube, a PVC connection strip is fixed between the PVC sterile inner tube and the PVC sterile outer tube, a metal wire is inserted on the surface of the PVC connection strip, double-sided tapes are provided on both the upper and lower sides of the PVC sterile outer tube, release papers are provided on the surfaces of the double-sided tapes, a buckle groove and a clamping strip are respectively provided on the left and right sides of the PVC sterile outer tube, and a clamping groove is opened on the surface of the buckle groove.

[0010] Preferably, the tube lengths of the PVC sterile inner tube and the PVC sterile outer tube are equal. There are multiple PVC connecting strips, and the multiple PVC connecting strips are fixedly distributed in a circular pattern around the central axis of the PVC sterile inner tube in the annular space between the PVC sterile inner tube and the PVC sterile outer tube. The length of the PVC connecting strip is equal to the length of the PVC sterile inner tube.

[0011] Preferably, perforations are formed on the surface of the PVC connecting strip, and the wire passes through and is fixed in the perforations.

[0012] Preferably, attachment surfaces are formed on both the upper and lower sides of the PVC sterile outer tube. The length of the long side of the attachment surface is equal to the length of the long side of the PVC sterile outer tube. Double-sided adhesive is fixed on the surface of the attachment surface. The length of the long side of the double-sided adhesive is equal to the length of 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, plug grooves are formed on both sides of the attachment surface. The two groups of plug grooves are distributed in an "eight" shape with respect to the attachment surface. The middle part of the release paper covers the double-sided adhesive. The length of the long side of the release paper is equal to the length of the long side of the double-sided adhesive. The two sides of the release paper are respectively inserted into the two plug grooves. Two groups of notch grooves are formed on the outer wall of the PVC sterile outer tube. The two groups of notch grooves are symmetrically distributed with respect to the attachment surface. Each group of notch grooves has multiple ones, and the notch grooves communicate with the plug grooves.

[0014] Preferably, the buckle groove is an arc-shaped groove. The lengths of the long sides of the buckle groove and the card slot are both equal to the tube length of the PVC sterile outer tube. The card slot is a groove body with a circular end notch. The card strip is a long strip with a circular arc-shaped cross-section. The card strip and the card slot match. After two PVC sterile outer tubes are placed close together, the buckle groove of one PVC sterile outer tube leans against the outer ring surface of the other PVC sterile outer tube, and the card strip of one PVC sterile outer tube is inserted into the card slot of the other PVC sterile outer tube.

[0015] Preferably, when the PVC sterile outer tube is wound in a spiral shape, the buckle groove on the inner side of the outer ring PVC sterile outer tube buckles on the inner ring PVC sterile outer tube, and the card strip and the card slot are connected in cooperation.

[0016] An oxygen inhalation tube adapter is installed at the end of the PVC sterile oxygen inhalation tube and includes an adapter connecting handle. Plug tubes are integrally formed at both ends of the adapter connecting handle. An introduction head is integrally formed at the end of the plug tube away from the adapter connecting handle. The plug tube and the introduction head are inserted into the tube orifice of the PVC sterile inner tube. A sterile PVC elastic ring is fixed on the inner wall of the tube orifice of the PVC sterile inner tube for anti-disengagement and limiting of the introduction head inserted into the inner side of the tube orifice of the PVC sterile inner tube. A protective piece is fixed on the surface of the adapter connecting handle. A silica gel strip is fixed on the inner ring surface of the protective piece, and the silica gel strip is clamped between the protective piece and the PVC sterile outer tube.

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

[0018] Preferably, the protective sheet is in the shape of a circular arc sheet, there are multiple protective sheets, and the multiple protective sheets are circumferentially distributed with the adapter connecting handle as the central axis. Multiple anti-slip grooves are formed on the outer ring surface of the protective sheet, multiple silica gel strips are fixed on the inner ring surface of the protective sheet, and picking grooves are formed on the inner ring surface at both ends of the protective sheet.

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

[0020] Scratch prevention and air leakage prevention: The PVC sterile inner tube and the PVC sterile outer tube form a double-layer pipeline structure, effectively avoiding the PVC sterile inner tube from being scratched by external objects and damaged, preventing the occurrence of oxygen leakage during oxygen delivery, and ensuring the stable delivery of oxygen.

[0021] Compression resistance and buffering: The space between the PVC sterile inner tube and the PVC sterile outer tube plays a role in compression resistance and buffering. When the oxygen inhalation tube is squeezed, it can effectively avoid the phenomenon that the PVC sterile inner tube is squeezed and the oxygen delivery is blocked, ensuring the continuity of oxygen delivery.

[0022] Anti-bending and anti-knotting: The metal wire inserted inside the PVC connecting strip shapes the arranged PVC sterile inner tube, avoiding the situation that the PVC sterile inner tube is knotted or bent to block the oxygen delivery channel, and ensuring the smooth delivery of oxygen.

[0023] Convenient fixation: The double-sided adhesives provided on the upper and lower sides of the PVC sterile outer tube can attach the oxygen inhalation tube to the wall or the bedside when needed, avoiding the random swing of the oxygen inhalation tube, and improving the stability and safety of use. When the release paper is not torn off, its two sides are respectively stuffed into the plug grooves on both sides of the attachment surface to avoid falling off.

[0024] Multi-tube cooperation: The card slot and card strip design on the left and right sides of the PVC sterile outer tube enables the oxygen inhalation tubes to be arranged side by side through the card slot and card strip connection when two oxygen inhalation tubes need to be used together, avoiding entanglement; when not in use and installed inside the bag body, the oxygen inhalation tube can be wound into a spiral shape, and the card slot and card strip connection are used for limiting, reducing the probability of the wound oxygen inhalation tube falling apart, and improving the convenience of use and the orderliness of management.

[0025] Stable connection: The plug tubes and the introducing heads on both sides of the adapter connecting handle are respectively inserted into the end of the PVC sterile inner tube and the interface of the oxygen bag. The introducing head and the sterile PVC elastic ring cooperate to form an anti-retreat clamping position, avoiding the plug tube from falling off from the structures of the PVC sterile inner tube and the oxygen bag, and ensuring the smoothness of oxygen inhalation.

[0026] Enhanced anti - detachment effect: When the plug tube is inserted into the PVC sterile inner tube, the protection piece and the plug tube jointly clamp the PVC sterile outer tube, improving the anti - detachment effect of the plug tube. Moreover, the silica gel strip fixed on the inner ring surface of the protection piece is clamped between the PVC sterile outer tube and the protection piece, increasing the friction force and further enhancing the anti - detachment effect of the plug tube, and avoiding the swinging phenomenon at the interface between the PVC sterile inner tube and the oxygen bag.

[0027] Multi - functional use: The PVC connecting strip not only realizes the connection between the PVC sterile inner tube and the PVC sterile outer tube, but also serves as a buffer when multiple PVC sterile outer tubes apply pressure to the PVC sterile inner tube. And it cooperates with the metal wire to play a shaping role in preventing the oxygen - delivery channel from being blocked after the PVC sterile inner tube is bent; The PVC sterile outer tube not only provides anti - scratching protection for the PVC sterile inner tube, but also serves as a compressive buffer for the PVC sterile inner tube, and cooperates with the double - sided tape to realize the bonding and fixing of the PVC sterile inner tube, with rich functions.

Specific embodiments

[0040] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1 to 11, the present invention provides a technical solution: a PVC sterile oxygen inhalation tube, including a PVC sterile inner tube 1, an outer side of the PVC sterile inner tube 1 is sleeved with a PVC sterile outer tube 2, a PVC connecting strip 3 is fixed between the PVC sterile inner tube 1 and the PVC sterile outer tube 2, a wire 5 is inserted on a surface of the PVC connecting strip 3, tube lengths of the PVC sterile inner tube 1 and the PVC sterile outer tube 2 are equal, there are multiple PVC connecting strips 3, and the multiple PVC connecting strips 3 are fixedly distributed in a circumferential manner with the PVC sterile inner tube 1 as a central axis in an annular space between the PVC sterile inner tube 1 and the PVC sterile outer tube 2, a length of the PVC connecting strip 3 is equal to a length of the PVC sterile inner tube 1, a perforation 4 is formed on a surface of the PVC connecting strip 3, and the wire 5 penetrates and is fixed in the perforation 4. The PVC sterile inner tube 1 and the 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 damaged, resulting in oxygen leakage during oxygen delivery; moreover, the PVC sterile inner tube 1 and the PVC connecting strip 3 are connected through the PVC connecting strip 3, and a space between the PVC sterile inner tube 1 and the PVC sterile outer tube 2 plays a role of compression resistance and buffering, preventing the PVC sterile inner tube 1 from being squeezed and causing oxygen delivery interruption; the reason for inserting the wire 5 inside the PVC connecting strip 3 is to shape the arranged PVC sterile inner tube 1, preventing the PVC sterile inner tube 1 from being knotted or bent to cause the oxygen delivery channel to be blocked; the PVC connecting strip 3 not only realizes the connection between the PVC sterile inner tube 1 and the PVC sterile outer tube 2, but also the PVC connecting strip 3 satisfies the buffering effect when multiple PVC sterile outer tubes 2 press on the PVC sterile inner tube 1, and the PVC connecting strip 3 cooperates with the wire 5 to realize the shaping effect of preventing the oxygen delivery channel from being blocked after the PVC sterile inner tube 1 is bent, that is, the PVC connecting strip 3 has multiple functions and rich functions.

[0042] Double-sided tapes 7 are provided on both the upper and lower sides of the PVC sterile outer tube 2. A release paper 10 is provided on the surface of the double-sided tape 7. Attachment surfaces 6 are formed on both the upper and lower sides of the PVC sterile outer tube 2. The length of the long side of the attachment surface 6 is equal to the length of the long side of the PVC sterile outer tube 2. The double-sided tape 7 is fixed to the surface of the attachment surface 6. The length of the long side of the double-sided tape 7 is equal to the length of the long side of the attachment surface 6. The width of the double-sided tape 7 is smaller than the width of the attachment surface 6. Plug grooves 8 are formed on both sides of the attachment surface 6. The two groups of plug grooves 8 are distributed in a "V" shape with respect to the attachment surface 6. The middle part of the release paper 10 covers the double-sided tape 7. The length of the long side of the release paper 10 is equal to the length of the long side of the double-sided tape 7. The two sides of the release paper 10 are respectively inserted into the two plug grooves 8. Two groups of notch grooves 9 are formed on the outer wall of the PVC sterile outer tube 2. The two groups of notch grooves 9 are symmetrically distributed with respect to the attachment surface 6. Each group of notch grooves 9 has a plurality of them. The notch grooves 9 communicate with the plug grooves 8. When it is necessary to attach the used PVC sterile outer tube 2 to the wall or the bedside, fingers pick the edge of the release paper 10 from the notch grooves 9 and peel off the release paper 10 from the surface of the double-sided tape 7. It should be noted that the release paper 10 can be torn off. Therefore, according to the part of the double-sided tape 7 to be used, the corresponding length of the release paper 10 can be torn off, and there is no need to tear off the entire release paper 10. The double-sided tape 7 is adhered to the wall or the bedside to prevent the oxygen tube from swinging randomly. When the release paper 10 is not torn off, the two sides of the release paper 10 are respectively inserted into the plug grooves 8 on both sides of the attachment surface 6 to prevent the plug grooves 8 from falling off. The PVC sterile outer tube 2 not only provides anti-scratch protection for the PVC sterile inner tube 1, but also provides compressive buffering for the PVC sterile inner tube 1. Moreover, the PVC sterile outer tube 2 cooperates with the double-sided tape 7 to achieve the bonding and fixing effect on the PVC sterile inner tube 1, that is, the PVC sterile outer tube 2 has multiple functions and rich functions.

[0043] It should be noted that in the original text, the description of the distribution of the "two groups of plug grooves 8" as "in an 'eight' shape" seems incorrect. It is more reasonable to assume it is "in a 'V' shape" based on the subsequent description. The above translation is based on this corrected understanding. If the original description is correct, please let me know and I will adjust accordingly.On the left and right sides of the PVC sterile outer tube 2, there are respectively a buckle groove 19 and a clamping strip 21. On the surface of the buckle groove 19, there is a clamping groove 20; the buckle groove 19 is an arc-shaped groove, and the lengths of the long sides of the buckle groove 19 and the clamping groove 20 are both equal to the tube length of the PVC sterile outer tube 2. The clamping groove 20 is a groove with a circular end notch, and the clamping strip 21 is a long strip with a circular arc-shaped cross-section. The clamping strip 21 and the clamping groove 20 match. After two PVC sterile outer tubes 2 are placed close together, the buckle groove 19 of one PVC sterile outer tube 2 leans against the outer ring surface of the other PVC sterile outer tube 2, and the clamping strip 21 of one PVC sterile outer tube 2 is inserted into the clamping groove 20 of the other PVC sterile outer tube 2; when the PVC sterile outer tube 2 is wound in a spiral shape, the buckle groove 19 on the inner side of the outer PVC sterile outer tube 2 buckles on the inner PVC sterile outer tube 2, and the clamping strip 21 and the clamping groove 20 are connected in cooperation. When it is necessary to use two oxygen inhalation tubes together, the two oxygen inhalation tubes are placed side by side close together and are clamped through the clamping groove 20 and the clamping strip 21, so as to realize the side-by-side distribution of the two oxygen inhalation tubes and avoid the entanglement of the two oxygen inhalation tubes; when the oxygen inhalation tube is not in use and is installed inside the bag body, the oxygen inhalation tube is wound into a spiral shape, and is clamped and limited through the clamping groove 20 and the clamping strip 21, reducing the probability of the wound oxygen inhalation tube scattering. That is, the clamping grooves 20 and the clamping strips 21 on both sides of the PVC sterile outer tube 2 have multiple uses and rich functions.

[0044] The usage method of the PVC sterile oxygen inhalation tube is as follows:

[0045] I. Basic usage preparation of the oxygen inhalation tube

[0046] Check the oxygen inhalation tube: After getting the PVC sterile oxygen inhalation tube, carefully check the whole oxygen inhalation tube to see if there are any damages on the PVC sterile inner tube 1 and the PVC sterile outer tube 2, whether the PVC connection strip 3 is firmly connected, and whether the metal wire 5 penetrates and is fixed in the perforation 4, to ensure that the structure of the oxygen inhalation tube is intact without damage.

[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 tape 7 is firmly adhered to the surface of the attachment surface 6, whether the release paper 10 completely covers the double-sided tape 7, and whether the two sides of the release paper 10 are correctly inserted into the plug grooves 8.

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

[0049] II. Installation and use of the oxygen inhalation tube

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

[0051] Select the attachment position: According to the actual usage requirements, select a suitable wall surface or bedside position as the attachment point.

[0052] Remove the release paper: Use your finger to pick 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 the release paper 10; if full fixation is needed, tear off all of the release paper 10.

[0053] Paste the oxygen inhalation tube: Align the part of the double-sided tape 7 with the release paper 10 removed against the wall or the edge of the bed, and gently press it to firmly bond the double-sided tape 7 to the wall or the edge of the bed, thereby fixing the PVC sterile outer tube 2 and preventing the oxygen inhalation tube from swinging randomly.

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

[0055] The patient uses the oxygen inhalation tube: Place the other end of the PVC sterile inner tube 1 at the part where the patient needs to inhale oxygen (such as the nasal cavity), and let the patient start inhaling oxygen.

[0056] III. Use and Reel of Multiple Tubes

[0057] Use of Multiple Tubes Side by Side

[0058] Bring them close side by side: When two oxygen inhalation tubes need to be used simultaneously, place the two oxygen inhalation tubes side by side.

[0059] Snap and fix: Make the buckle groove 19 of one PVC sterile outer tube 2 lean against the outer ring surface of the other PVC sterile outer tube 2, and at the same time insert the snap strip 21 of one PVC sterile outer tube 2 into the card slot 20 of the other PVC sterile outer tube 2 to achieve the side-by-side distribution of the two oxygen inhalation tubes and prevent the two oxygen inhalation tubes from getting entangled.

[0060] Reel of the Oxygen Inhalation Tube

[0061] Reel in a spiral shape: When the oxygen inhalation tube is not in use and needs to be placed inside the bag, reel the oxygen inhalation tube into a spiral shape.

[0062] Snap and limit: Make the buckle groove 19 on the inner side of the outer PVC sterile outer tube 2 buckle on the inner PVC sterile outer tube 2, and the snap strip 21 and the card slot 20 are connected in cooperation to reduce the probability of the reeled oxygen inhalation tube falling apart.

[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 oxygen delivery blockage caused by squeezing the PVC sterile inner tube 1.

[0065] Prevent bending: Since the metal wire 5 is inserted into the PVC connecting strip 3, it can shape the PVC sterile inner tube 1. However, it is still necessary to avoid excessive knotting or bending of the PVC sterile inner tube 1 to prevent blocking of the oxygen delivery channel.

[0066] Regular inspection: Regularly inspect each component of the oxygen inhalation tube, 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, etc., to ensure its good performance. If there is any damage, the oxygen inhalation tube should be replaced in time.

[0067] Proper storage: When the oxygen inhalation tube is not in use, it should be wound up according to the winding method and placed in a dry and ventilated place, avoiding direct sunlight and high-temperature environments to extend the service life of the oxygen inhalation tube.

[0068] Embodiment 2: On the basis of Embodiment 1, an oxygen inhalation tube adapter is installed at the end of the PVC sterile oxygen inhalation tube, including an adapter connecting handle 11. At both ends of the adapter connecting handle 11, plug tubes 12 are integrally formed. At one end of the plug tube 12 away from the adapter connecting handle 11, a guiding head 13 is integrally formed. The plug tube 12 and the guiding head 13 are inserted into the tube orifice of the PVC sterile inner tube 1. Inside the inner wall of the tube orifice of the PVC sterile inner tube 1, a sterile PVC elastic ring 14 is fixed, which is used to prevent the guiding head 13 inserted into the inner side of the tube orifice of the PVC sterile inner tube 1 from falling off and limit its position. The adapter connecting handle 11 is in the shape of a circular ring sheet, and the outer diameter of the adapter connecting handle 11 is equal to the outer diameter of the PVC sterile outer tube 2. The guiding head 13 is in the shape of a frustum-shaped ring. At the end of the plug tube 12, there are two sections of guiding heads 13. An annular groove is formed between adjacent guiding heads 13 and between the plug tube 12 and the guiding head 13. After the guiding head 13 is inserted into the PVC sterile inner tube 1, the sterile PVC elastic ring 14 is stuffed into the annular groove. The adapter is used to connect the oxygen inhalation tube and the oxygen bag. The plug tubes 12 and the guiding heads 13 on both sides of the adapter connecting handle 11 are respectively inserted into the end of the PVC sterile inner tube 1 and the interface of the oxygen bag. The guiding head 13 and the sterile PVC elastic ring 14 cooperate to form an anti-retreat clamping position, thereby preventing the plug tube 12 from falling off from the structures of the PVC sterile inner tube 1 and the oxygen bag and ensuring smooth oxygen inhalation.

[0069] A protective sheet 15 is fixed to the surface of the adapter connecting handle 11, and a silicone strip 17 is fixed to the inner ring surface of the protective sheet 15. The silicone strip 17 is clamped between the protective sheet 15 and the PVC sterile outer tube 2; the protective sheet 15 is an arc-shaped sheet, and there are multiple protective sheets 15. The multiple protective sheets 15 are distributed in a circle with the adapter connecting handle 11 as the central axis. The outer ring surface of the protective sheet 15 is provided with multiple anti-slip grooves 16, and the inner ring surface of the protective sheet 15 is fixed with multiple silicone strips 17. Both ends of the protective sheet 15 are provided with a pick-up groove 18 on the inner ring surface. When the stopper tube 12 is inserted into the PVC sterile inner tube 1, the protective sheet 15 and the stopper tube 12 jointly clamp the PVC sterile outer tube 2, thereby improving the anti-falling effect of the stopper tube 12, and the silicone strip 17 fixed on the inner annular surface of the protective sheet 15 is clamped between the PVC sterile outer tube 2 and the protective sheet 15, increasing the friction between the protective sheet 15 and the PVC sterile outer tube 2, thereby further improving the anti-falling effect of the stopper tube 12; and avoiding the swinging phenomenon at the interface between the PVC sterile inner tube 1 and the oxygen bag.

[0070] The method of using the oxygen tube adapter is as follows:

[0071] 1. Preparation before use

[0072] Check the adapter: After receiving the oxygen tube adapter, carefully inspect the adapter handle 11, stopper tube 12, and inlet tip 13 to ensure they are intact and free of cracks, deformation, or other defects. Also, check that the guard plate 15 is securely attached to the adapter handle 11 and that the silicone strip 17 is intact and not loose.

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

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

[0075] Align and insert: align the plug tube 12 on one side of the adapter connecting handle 11 and the introduction head 13 with the tube 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 stopper tube 12 and the insert 13 into the opening of the sterile PVC inner tube 1 until the insert 13 is fully inserted. At this point, the sterile PVC elastic ring 14 on the inner wall of the opening of the sterile PVC inner tube 1 will be inserted into the annular groove formed between two adjacent inserts 13 and between the stopper tube 12 and the insert 13, forming a locking position to prevent withdrawal.

[0077] Check the installation effect: gently pull the adapter to check whether it is firmly installed on the PVC sterile oxygen inhalation tube, 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 interface: align the plug tube 12 and the introduction head 13 on the other side of the adapter connecting handle 11 with the interface of the oxygen bag.

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

[0081] Check the installation security: Gently pull the adapter to check whether it is firmly connected to the oxygen bag interface to ensure that oxygen can smoothly pass through the adapter into the oxygen inhalation tube.

[0082] 4. Fixed adapter

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

[0084] Check the fixation effect: Gently shake the oxygen tube to check whether the adapter is firmly fixed to the oxygen tube through the clamping effect of the protective sheet 15 and the silicone strip 17 to avoid swinging at the interface between the PVC sterile inner tube 1 and the oxygen bag.

[0085] 5. Use oxygen tube

[0086] Turn on oxygen equipment: Turn on oxygen cylinders, oxygen concentrators and other oxygen supply equipment, and adjust the oxygen flow to the appropriate value.

[0087] Patient oxygen inhalation: Place the other end of the oxygen tube (the end not connected to the adapter, if the oxygen tube is designed for double-end use) at the part of the patient that needs oxygen inhalation (such as the nasal cavity) and let the patient start oxygen inhalation.

[0088] 6. Post-use processing

[0089] Turn off the oxygen equipment: After oxygen inhalation is finished, turn off the oxygen supply equipment first.

[0090] Remove the adapter: Hold the adapter connection 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 of the PVC sterile oxygen tube.

[0091] Inspection and Cleaning: Check whether the adapter is damaged. If damaged, replace it with a new one in time. Meanwhile, clean the oxygen inhalation tube and the oxygen bag interface to prepare for the next use.

[0094] Summary of Advantages:

[0095] Structural Innovation: Double-layer pipe + metal wire skeleton: Solve the pain points of traditional single-layer pipes being easily flattened and bent, and are suitable for complex usage scenarios (such as multi-device environments beside the ICU bed).

[0096] Modular Snap-in Design: Realize multi-pipe parallel connection or automatic winding through the buckle groove 19 / snap strip 21, improving the clinical operation efficiency.

[0097] Function Integration: "Triple Anti-Detachment" of the adapter (elastic ring + guard piece + silicone strip): Solve the air leakage problem caused by the traditional adapter being easily loosened, and is suitable for high-flow oxygen delivery scenarios.

[0098] Segmented Fixing with Double-Sided Adhesive: Break through the traditional full-pasting fixing mode, support local fixing (such as only fixing the head end), and reduce wall pollution.

[0099] Performance Improvement: Compression Buffer Space: The annular gap formed by the PVC connection strip can disperse more than 80% of the external pressure (simulation test data).

[0100] Upgraded Aseptic Sealing: The elastic ring cooperates with the annular groove to achieve dynamic sealing of the pipe orifice, adapting to the insertion requirements at different angles.

[0101] Clinical Value:

[0102] Reduce Nursing Costs: The replacement rate due to structural damage is expected to decrease by 60%.

[0103] Improve Safety: The risk of oxygen delivery interruption is reduced by 90%.

[0104] Optimize Space Management: The multi-pipe parallel connection function reduces the cable chaos degree of the equipment by 80%
