Description

Technical Field

[0001] The invention relates to the technical field of oxygen-absorbing masks, in particular to a novel oxygen-absorbing mask capable of adjusting breathing flow. Background Art

[0002] At present, in the medical field, oxygen masks are commonly used oxygen therapy equipment. Traditional oxygen masks have obvious deficiencies in regulating respiratory flow, and their adjustment methods are often not precise and flexible enough to meet the complex and diverse needs of patients. Moreover, during the oxygen supply process, affected by environmental factors and the quality of the oxygen source itself, some impurities or tiny particles may mix into the oxygen and enter the mask. These pollutants will pose a potential threat to the patient's fragile respiratory tract, affect the treatment effect, and may even aggravate the condition.

[0003] With the continuous advancement of medical technology and the high attention paid to the treatment effect and safety of patients, on the one hand, the function of accurately regulating the respiratory flow rate is becoming more and more critical. Taking the intensive care unit as an example, the severity of the patient's condition and respiratory condition vary significantly; some patients are in critical condition and need a large amount of high-flow oxygen to maintain vital signs; while other patients are in the recovery stage and only need a lower and stable flow rate to assist recovery. On the other hand, in order to ensure the purity of the inhaled oxygen, the setting of the filter is essential, but after long-term use, if the filter is not cleaned or replaced in time, it is easy to accumulate dirt and breed bacteria, affecting the patient's recovery effect, thereby reducing the flexibility and convenience of using the oxygen mask.

[0004] In view of this, we propose a new oxygen mask with adjustable breathing flow. Summary of the invention

[0005] The purpose of the present invention is to provide a novel oxygen breathing mask with adjustable breathing flow to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a novel oxygen inhalation mask with adjustable respiratory flow, comprising an oxygen inhalation body, a connecting tube, an oxygen inhalation tube and an oxygen inhalation mask body, wherein one end of the connecting tube away from the oxygen inhalation body and one end of the oxygen inhalation tube away from the oxygen inhalation mask body are both provided with connecting pieces, and a respiratory flow control piece capable of adjusting the respiratory flow is provided between the two connecting pieces, wherein:

[0007] The respiratory flow control element at least comprises a housing, a control assembly is disposed inside the housing, mounting baskets are disposed at both ends of the control assembly, both sides of the mounting baskets are slidably connected to the inner wall of the housing through a sliding assembly, and a filter plate capable of reducing dust particles in oxygen is engaged with one end of the mounting basket away from the control assembly through a snap-fit ​​assembly;

[0008] The control component can adjust the flow rate of oxygen absorption and drive the filter plate to move its position at the same time;

[0009] When the control component adjusts the oxygen absorption flow rate to the maximum, the filter plate is moved to the outside of the shell, and the filter plate is disassembled. When the control component adjusts the oxygen absorption flow rate to a small level, the filter plate can not only be moved to the inside of the shell, but also play a guiding role in the flow of gas.

[0010] As a further improvement of the present technical solution, the control component includes at least a control panel, a fixing component capable of stabilizing the position of the control panel is arranged inside the control panel, a spring sheet is arranged at one end of the control panel located inside the shell, and both ends of the spring sheet are respectively fixedly connected to one side of one side of two mounting baskets.

[0011] As a further improvement of the present technical solution, two installation grooves are provided inside the control panel, and elastic parts are arranged inside the two installation grooves. A control rod is provided at one end of the elastic part close to the side opening of the control panel, and a fixing block is provided at one end of the control rod away from the elastic part, and fixing grooves that can be plugged into and matched with the fixing blocks are provided on both sides of the inner wall of the shell.

[0012] As a further improvement of the technical solution, the side of the spring away from the control panel is made of polytetrafluoroethylene material.

[0013] As a further improvement of the technical solution, slide grooves are provided on both sides of the two ends inside the shell, and sliding blocks that can be slidably connected to the slide grooves are provided on both sides of the installation basket.

[0014] As a further improvement of the technical solution, a slot is provided on a side of the installation basket away from the spring sheet, and a clamping plate capable of clamping with the slot is provided on a side of the filter plate close to the installation basket.

[0015] As a further improvement of the technical solution, elastic sealing strips are provided inside the two slide grooves on the side away from the control panel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the novel oxygen mask with adjustable respiratory flow, the control component drives the filter plate to move to adjust the oxygen flow. When the flow is adjusted to the maximum, the filter plate can be easily removed; when it is adjusted to a small amount, it can not only move the filter plate, but also play a role in diversion, and can effectively adjust the flow rate and flow of oxygen, so that oxygen can be more fully utilized, reduce unnecessary oxygen waste, reduce medical costs, and adjust the oxygen flow according to the patient's treatment stage or condition changes, avoiding the discomfort caused to the patient by a sudden increase or decrease in the oxygen flow, thereby improving the flexibility and convenience of using the oxygen mask.

[0018] 2. In this new oxygen mask with adjustable respiratory flow, the filter plate is connected to the installation basket with a snap-on assembly, which is convenient for disassembly, cleaning and replacement, and improves the installation efficiency. The snap-on fit is not only easy to operate, but also ensures a stable installation, effectively preventing the filter plate from shifting or loosening, and enhancing the stability of the filtering effect. At the same time, the setting of the sliding assembly and the elastic sealing strip ensures the smooth movement and sealing of the installation basket, reduces noise and wear, extends the service life, and improves the user experience of the oxygen mask, so that it maintains good performance during long-term use.

[0019] 3. In the new oxygen mask with adjustable respiratory flow, the position of the control panel is adjusted by holding the control lever tightly, so that the oxygen flow can be flexibly adjusted, and it can be stabilized after releasing it. The spring piece is deformed during the adjustment process, which not only plays a guiding role, but also improves the flexibility of the oxygen mask. The elastic force of the fixed component can stabilize the position of the control panel, avoid oxygen flow fluctuations, and effectively meet the needs of different patients. At the same time, it reduces the maintenance cost and maintenance frequency of the equipment, extends the service life of the oxygen mask, and thus improves the practicality and reliability of the oxygen mask.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] See also Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide a new type of oxygen inhalation mask with adjustable breathing flow, including an oxygen inhalation body 10, a connecting tube 11, an oxygen inhalation tube 13 and an oxygen inhalation mask body 14, and the end of the connecting tube 11 away from the oxygen inhalation body 10 and the end of the oxygen inhalation tube 13 away from the oxygen inhalation mask body 14 are both provided with a connecting piece 12, and a breathing flow control piece 20 capable of adjusting the breathing flow is provided between the two connecting pieces 12, wherein:

[0035] The respiratory flow control element 20 at least comprises a housing 21, a control assembly 22 is disposed inside the housing 21, mounting baskets 30 are disposed at both ends of the control assembly 22, both sides of the mounting basket 30 are slidably connected to the inner wall of the housing 21 through a sliding assembly 31, and one end of the mounting basket 30 away from the control assembly 22 is snap-fitted with a filter plate 33 capable of reducing dust particles in oxygen through a snap-fit ​​assembly 32;

[0036] The control component 22 can adjust the flow rate of oxygen absorption and at the same time drive the filter plate 33 to move its position;

[0037] When the control component 22 adjusts the oxygen absorption flow rate to the maximum, the filter plate 33 is moved to the outside of the shell 21, and the filter plate 33 is disassembled. When the control component 22 adjusts the oxygen absorption flow rate to a small level, the filter plate 33 can not only be moved to the inside of the shell 21, but also can play a guiding role in the flow of gas.

[0038] Since different patients need different amounts of oxygen, their demands for oxygen flow are also different. Figure 4 , Figure 5 and Figure 8 It can be known that the specific structure of the control component 22 is disclosed. The control component 22 at least includes a control board 221. A fixing component 222 capable of stabilizing the position of the control board 221 is arranged inside the control board 221. A spring 223 is arranged at one end of the control board 221 located inside the shell 21. The two ends of the spring 223 are respectively fixedly connected to one side of the two mounting baskets 30.

[0039] It can be seen that when the fixing component 222 is tightly grasped to deform and enter the interior of the control plate 221, the position of the control plate 221 can be flexibly adjusted. At the same time, the spring piece 223 will be deformed accordingly, thereby driving the sliding component 31 to slide, thereby adjusting the position of the filter plate 33.

[0040] When the fixing component 222 is loosened, the position of the control board 221 is stabilized by the fixing component 222. At this time, the deformation of the spring piece 223 can not only play a role in guiding the flow, but also improve the flexibility of the use of the oxygen mask. Whether in the process of adjusting the respiratory flow or in the gas flow stage after the flow is fixed, it will not cause obstacles and influences to the normal flow of gas, ensuring the smooth and stable supply of oxygen, thereby improving the wide range and practicality of the use of the oxygen mask.

[0041] In order to further understand the specific structure of the fixing assembly 222, Figure 6 and Figure 7 It can be seen that two installation grooves 2221 are provided inside the control board 221, and elastic members 2222 are provided inside the two installation grooves 2221. A control rod 2223 is provided at one end of the elastic member 2222 close to the side opening of the control board 221, and a fixing block 2224 is provided at one end of the control rod 2223 away from the elastic member 2222. Fixed grooves 2225 that can be plugged into the fixing block 2224 are provided on both sides of the inner wall of the shell 21.

[0042] The improvement is that by tightly gripping the two control rods 2223, the two control rods 2223 are brought close to each other, and at the same time, the elastic member 2222 is also deformed and contracted, and the fixing block 2224 enters the interior of the mounting groove 2221. At this time, the position of the control board 221 can be moved to achieve the effect of adjusting the oxygen flow rate. Similarly, by loosening the two control rods 2223, the fixing block 2224 is plugged into the fixing groove 2225 through the rebound force of the elastic member 2222, and the rebound force of the elastic member 2222 makes the fixing block 2224 away from the elastic member One end of 2222 is tightly pressed against the inner wall of the fixing groove 2225. Here, the elastic force of the elastic member 2222 is greater than the elastic force of the spring 223. In order to prevent unstable fixation and affect the use effect, it can not only adjust and stably fix the position of the control board 221 to control the oxygen flow rate to meet the needs of different patients, but also effectively avoid the oxygen flow fluctuation caused by loose fixation during use, ensure the stability and reliability of the oxygen supply, and at the same time, reduce the maintenance cost and repair frequency, thereby extending the service life of the oxygen mask.

[0043] During use, the filter plate 33 can only reduce the presence of dust particles, but cannot completely avoid the presence of dust particles. Therefore, it is inevitable that dust particles will adhere to the side of the spring piece 223 away from the control plate 221, which will affect the effect of the respiratory flow control element 20 for a long time. Therefore, according to Figure 6 and Figure 8 It can be seen that the side of the spring 223 away from the control board 221 is made of polytetrafluoroethylene material. Polytetrafluoroethylene has an extremely low friction coefficient and good anti-stickiness, which can effectively reduce the adhesion of dust particles, resist the erosion of oxygen and other possible chemical substances, and extend the service life of the spring 223, thereby ensuring the long-term, stable and effective use of the respiratory flow control component 20.

[0044] In order to facilitate the removal or replacement of the filter plate 33, Figure 4 , Figure 5 and Figure 8 It can be known that both sides of the two ends of the shell 21 are provided with sliding grooves 312 , and both sides of the mounting basket 30 are provided with sliding blocks 311 that can be slidably connected with the sliding grooves 312 .

[0045] It can be seen that when the position of the control board 221 is adjusted, the slider 311 will slide inside the slide groove 312, limiting the moving position of the mounting basket 30, improving the stability of the position movement of the mounting basket 30, preventing jamming, and facilitating the later disassembly and cleaning of the filter plate 33 and replacement of the new filter plate 33, thereby reducing the need to replace the oxygen mask as a whole due to aging or damage of the filter plate 33, reducing maintenance costs, and at the same time, avoiding the problem of reduced filtering effect due to long-term use without replacing the filter plate 33, ensuring that the oxygen mask can provide good filtering performance, thereby improving the practicality of the oxygen mask.

[0046] Considering that the filter plate 33 needs to be disassembled regularly, the old filter plate 33 needs to be cleaned and then installed, or a new filter plate 33 needs to be directly replaced. In order to improve the efficiency of the installation and removal of the filter plate 33, according to Figure 3 It can be seen that a slot 322 is provided on a side of the installation basket 30 away from the spring sheet 223 , and a clamping plate 321 capable of clamping with the slot 322 is provided on a side of the filter plate 33 close to the installation basket 30 .

[0047] The use of a simple clamping plate 321 and a clamping slot 322 for clamping cooperation not only facilitates operation, reduces production costs, improves installation efficiency, and reduces time consumption, but also the flow of gas will not cause the clamping plate 321 and the clamping slot 322 to be disconnected, effectively avoiding displacement or loosening of the filter plate 33 due to vibration or other external forces, thereby increasing the stability of the filtering effect and reducing the possibility of gas leakage from the clamping joint, ensuring that the gas is effectively filtered through the filter plate 33, thereby improving the convenience of use.

[0048] Since the movement of the installation basket 30 is controlled by the elasticity of the spring sheet 223, and the spring sheet 223 is only located on one side of the installation basket 30, in order to increase the stability of the movement of the installation basket 30, according to Figure 4 , Figure 5 and Figure 8 It can be seen that elastic sealing strips 34 are provided inside the two slide grooves 312 on the side away from the control board 221. When the slider 311 is away from the control board 221, the elastic sealing strip 34 will be deformed and elongated, which can not only seal the control component 22 to prevent dust, water vapor and other impurities from entering and affecting normal operation, but also the resilience of the elastic sealing strip 34 can assist in the smooth adjustment of the position of the installation basket 30, ensure that the installation basket 30 maintains balance during movement, avoid tilting or jamming, and the elastic sealing strip 34 reduces the wear between the slider 311 and the slide groove 312, thereby extending the service life.

[0049] In summary, the working principle of the present invention is as follows: first, the connecting tube 11, the respiratory flow control element 20 and the oxygen inhalation tube 13 are connected using the two connecting pieces 12. Then, the two control rods 2223 are tightly gripped to bring the two control rods 2223 closer together. At the same time, the elastic element 2222 is also deformed and contracted, and the fixing block 2224 enters the interior of the mounting groove 2221. At this time, the position of the control plate 221 can be moved. At the same time, the spring piece 223 is deformed accordingly, and the slider 311 is in the slide groove 312. The elastic sealing strip 34 will also be deformed and elongated. After the control panel 221 is moved to the specified position, the two control rods 2223 are released, and the fixing block 2224 is plugged into the fixing groove 2225 through the resilience of the elastic member 2222. Moreover, the resilience of the elastic member 2222 makes the end of the fixing block 2224 away from the elastic member 2222 tightly press against the inner wall of the fixing groove 2225, thereby completing the work of adjusting the breathing flow of the oxygen mask.

[0050] When the filter plate 33 needs to be replaced, first, hold the two control rods 2223 tightly to bring the two control rods 2223 closer to each other. At the same time, the elastic member 2222 also deforms and contracts, and the fixing block 2224 enters the interior of the mounting groove 2221. At this time, the control plate 221 is pulled toward the outside of the shell 21, and the spring piece 223 is in the shape of a "1". At the same time, the slider 311 slides inside the slide groove 312 to push the mounting basket 30 to the opening of the shell 21. Then, the filter plate 33 is pulled outward to disconnect the card plate 321 from the card slot 322. Then, take a new filter plate 33, align the card plate 321 with the opening of the card slot 322, and press it toward the mounting basket 30 to make the card plate 321 and the card slot 322 engage in a snap-fitting manner, and the replacement of the filter plate 33 is completed.
