Description

Technical Field

[0001] This utility model relates to the field of oxygen tube fixing technology, specifically a non-invasive ventilator mask oxygen tube fixing device. Background Technology

[0002] In clinical practice, the oxygen tubing of a traditional non-invasive ventilator mask is usually directly connected to the oxygen inlet on the ventilator mask. However, because the oxygen inlet end of the mask is relatively short and the end of the oxygen tubing connected to it is a smooth tube, the two are prone to detachment when connected, resulting in ineffective oxygen use for the patient. This can lead to changes in the patient's condition, and in severe cases, it can cause a decrease in the patient's blood oxygen saturation, endangering the patient's life.

[0003] Chinese utility model CN220213647U discloses a disposable oxygen mask, which includes an oxygen tube clamping structure. The principle is that one end of the oxygen tube is inserted into a fixed plate, and then a spring pushes a clamping block into a groove at one end of the oxygen tube, preventing the oxygen tube from being pulled out of the fixed plate. This completes the connection between the oxygen tube and the mask.

[0004] However, the existing device's fixing points are concentrated at the connection between the locking block and the locking slot. When the oxygen tube is pulled, the stress is concentrated at one point, which can easily cause damage. Therefore, a symmetrically restrained connection structure was designed to address the above-mentioned problem, making the stress more even and less prone to damage. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a non-invasive ventilator mask oxygen tube fixing device, which has the advantages of more even force distribution and less component damage when the oxygen tube is pulled, thus solving the problem of uneven force distribution in existing devices during use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a non-invasive ventilator mask oxygen tube fixing device, comprising: a mask with a connecting tube at its top; an oxygen tube inserted into the outer wall of the connecting tube; a connecting assembly on the connecting tube, the connecting assembly comprising: a retaining ring fixedly disposed on the outer wall of the bottom end of the oxygen tube; a connecting seat disposed on the outer wall of the connecting tube; a lever disposed on the inner side of the connecting seat and rotatably connected to the connecting seat; a locking block disposed on the top of the lever; and a spring disposed on the outer wall of the mask, with its other end connected to the lever.

[0009] In some embodiments, the connecting component further includes: a plurality of protrusions, all disposed on the outer side wall of the lever.

[0010] In some embodiments, the connecting assembly further includes: a positioning hole formed at the top of the retaining ring; and the bottom end of the positioning rod passing through the positioning hole and connected to the connecting tube.

[0011] In some embodiments, the connecting assembly further includes a cone disposed at the top of the positioning rod.

[0012] In some embodiments, the connection assembly further includes a sealing gasket disposed at the bottom of the retaining ring.

[0013] In some embodiments, the connecting pipe is provided with a spring-loaded assembly, the spring-loaded assembly comprising: a groove formed on the outer wall of the connecting pipe; a second spring disposed inside the groove; and a bottom end of a push rod inserted into the groove and connected to the second spring.

[0014] In some embodiments, the rebound assembly further includes: a vertical rod disposed inside the top rod, with its bottom end penetrating through the inner sidewall of the top rod and connected to the inner sidewall of the groove; and a stop block disposed at the top of the vertical rod.

[0015] In some embodiments, the rebound assembly is provided in three sets.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a non-invasive ventilator mask oxygen tubing fixing device, which has the following beneficial effects:

[0018] 1. This fixing device, through the design of the connecting component using a lever, locking block, and spring, allows the spring to rebound and rotate the lever after the retaining ring is tightly pressed against the connecting tube. This causes the locking block at one end of the lever to restrain the retaining ring, preventing it from detaching from the connecting tube and thus securing the oxygen tube and preventing it from falling off. Compared to existing devices, the locking blocks on both sides distribute the force evenly when pulled, making them less prone to damage.

[0019] 2. This fixing device, through the rebound assembly, can push the top rod chest groove body to extend out through the spring, thereby popping the retaining ring upward, so that the retaining ring can quickly disengage from the connecting tube, making it easy to use.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0030] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0032] In clinical practice, the oxygen tubing of a traditional non-invasive ventilator mask is usually directly connected to the oxygen inlet on the ventilator mask. However, because the oxygen inlet end of the mask is relatively short and the end of the oxygen tubing connected to it is a smooth tube, the two are prone to detachment when connected, resulting in ineffective oxygen use for the patient. This can lead to changes in the patient's condition, and in severe cases, it can cause a decrease in the patient's blood oxygen saturation, endangering the patient's life.

[0033] In related technologies, one end of the oxygen tube is inserted into a fixed plate, and then a spring pushes a locking block into a slot at one end of the oxygen tube, preventing the oxygen tube from being pulled out of the fixed plate. This completes the connection between the oxygen tube and the mask. However, in existing devices, the fixing point is concentrated at the connection between the locking block and the slot. When the oxygen tube is pulled, the stress is concentrated at one point, which can easily cause damage.

[0034] To address some of the problems in related technologies, this application provides a non-invasive ventilator mask oxygen tube fixing device. When it is necessary to fit the oxygen tube 13 onto the outer wall of the connecting tube 12 and fix it, the levers 23 on both sides of the connecting tube 12 can be pinched, causing the levers 23 to rotate in a circular motion around the part connected to the connecting seat 22, thus causing the top of the levers 23 to rotate and unfold. While rotating, the levers 23 compress the spring 25. Then, the oxygen tube 13 is fitted onto the outer wall of the connecting tube 12, so that the retaining ring 21 is close to the connecting tube 12. Then, the levers 23 are released, and the spring 25 rebounds, pushing the levers 23 to rotate. This causes the levers 23 to drive the bottom retaining ring 21 of the top retaining block 24 to restrict it, preventing the retaining ring 21 from detaching from the connecting tube 12, thereby completing the fixing of the oxygen tube 13.

[0035] This application is described below with reference to the accompanying drawings and specific embodiments:

[0036] Combination Figures 1-5This application provides a non-invasive ventilator mask oxygen tube fixing device, including: a mask 11 with a connecting tube 12 at its top; an oxygen tube 13 inserted into the outer wall of the connecting tube 12; a connecting assembly 2 on the connecting tube 12, the connecting assembly 2 including: a retaining ring 21 fixedly disposed on the outer wall of the bottom end of the oxygen tube 13; a connecting seat 22 disposed on the outer wall of the connecting tube 12; a lever 23 disposed on the inner side of the connecting seat 22 and rotatably connected to the connecting seat 22; a locking block 24 disposed on the top of the lever 23; and a spring 25 disposed on the outer wall of the mask 11, with its other end connected to the lever 23.

[0037] Specifically, the 3M 6000 mask (model 11) is typically used in conjunction with a non-invasive ventilator. A non-invasive ventilator is a medical device used to support respiration. Compared to traditional invasive ventilators, it does not require endotracheal intubation or tracheotomy to connect the ventilator to the patient's airway. Generally, non-invasive ventilators achieve respiratory support primarily through positive pressure ventilation, mask or nasal mask sealing, positive expiratory pressure, positive inspiratory pressure, pressure support, and ventilator settings and adjustments.

[0038] Positive pressure ventilation principle: Non-invasive ventilators deliver air to the patient's airway by generating a certain airflow and pressure. Providing positive pressure ventilation helps the patient overcome airway resistance and improves gas exchange.

[0039] Face mask or nasal mask seal: The patient uses a face mask or nasal mask to connect to the non-invasive ventilator. A sealed mask prevents airflow leakage and ensures effective airflow to the patient's airway.

[0040] Positive Expiratory Pressure (PEP): A positive expiratory pressure value is set in the ventilator settings. When the patient exhales, PEP keeps the airway open, reduces collapse and obstruction, and promotes gas expulsion.

[0041] Positive inspiratory pressure (PIP) and pressure support: The ventilator provides both positive inspiratory pressure and pressure support. PIP is a higher positive pressure used to help the patient inhale. Pressure support provides additional support pressure when the patient is actively inhaling, reducing the burden on the respiratory system.

[0042] Ventilator settings and adjustments: The parameters of the non-invasive ventilator can be adjusted according to the patient's needs, such as positive inspiratory pressure, positive expiratory pressure, and pressure support level. Healthcare professionals will set and adjust the parameters based on the patient's clinical condition and monitoring results.

[0043] The outer ring of the connecting tube 12 can be made of metal, and the retaining ring 21 is designed to be magnetic. When the oxygen tube 13 is inserted into the connecting tube 12 during installation, the retaining ring 21 and the connecting tube 12 magnetically adhere to each other, ensuring that the retaining ring 21 and the connecting tube 12 are in close contact. This makes it more convenient to use without having to manually hold the retaining ring 21 during installation.

[0044] When using the oxygen tube 13, to be fitted onto the outer wall of the connecting tube 12 and secured, the levers 23 on both sides of the connecting tube 12 can be pinched, causing the levers 23 to rotate in a circular motion around the part connected to the connecting seat 22, thus opening the top of the levers 23. While rotating, the levers 23 compress the spring 25. Then, the oxygen tube 13 is fitted onto the outer wall of the connecting tube 12, so that the retaining ring 21 is close to the connecting tube 12. Then, the levers 23 are released, and the spring 25 rebounds, pushing the levers 23 to rotate. This causes the levers 23 to drive the retaining block 24 at the top and the retaining ring 21 at the bottom to restrict the retaining ring 21 from detaching from the connecting tube 12, thereby completing the fixation of the oxygen tube 13.

[0045] In some embodiments, the connecting component 2 further includes: a plurality of protrusions 26, all disposed on the outer side wall of the lever 23.

[0046] The design of the raised strip 26 during use increases friction, making it less likely to slip when in contact with the fingers, and allowing for better pressing of the lever 23 to make it rotate.

[0047] In some embodiments, the connecting assembly 2 further includes: a positioning hole 27 formed at the top of the retaining ring 21; and a positioning rod 28 whose bottom end passes through the positioning hole 27 and is connected to the connecting tube 12.

[0048] When using the oxygen tube 13, the positioning rod 28 passes through the positioning hole 27 on the retaining ring 21, which can restrict the retaining ring 21 to prevent rotation and avoid the oxygen tube from getting tangled.

[0049] In some embodiments, the connecting assembly 2 further includes a cone 281 disposed at the top of the positioning rod 28.

[0050] When in use, the design of the pointed tip of the cone 281 makes it easier to pass through the inside of the positioning hole 27, and can play a guiding role.

[0051] In some embodiments, the connecting assembly 2 further includes a sealing gasket 29 disposed at the bottom of the retaining ring 21.

[0052] When in use, the design of the sealing gasket 29 can increase the sealing between the retaining ring 21 and the connecting pipe 12, thereby reducing oxygen leakage.

[0053] In some embodiments, the connecting pipe 12 is provided with a spring-loaded assembly 3, the spring-loaded assembly 3 comprising: a groove 31 formed on the outer side wall of the connecting pipe 12; a second spring 32 disposed inside the groove 31; and a bottom end of a push rod 33 inserted into the groove 31 and connected to the second spring 32.

[0054] When the retaining ring 21 is in contact with the connecting tube 12, it will push the push rod 33 to retract into the groove 31 and compress the spring 32. When the restriction on the retaining ring 21 is released, the spring 32 will rebound and push the push rod 33 to move upward, which can push the retaining ring 21 to move upward, so that after the lever 23 is released, the locking block 24 will not restrict the retaining ring 21.

[0055] In some embodiments, the rebound assembly 3 further includes: a vertical rod 34 disposed inside the top rod 33, with its bottom end penetrating through the inner sidewall of the top rod 33 and connected to the inner sidewall of the groove 31; and a stop block 35 disposed at the top of the vertical rod 34.

[0056] The design of the upright 34 and the stop 35 during use ensures that the push rod 33 will not detach from the inside of the groove 31, thus stabilizing the movement trajectory of the push rod 33.

[0057] In some embodiments, the springback assembly 3 is provided in three sets.

[0058] When in use, the three sets of rebound components can increase the rebound force and better push the retaining ring 21 to pop open.

[0059] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," and "some examples" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0060] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
