Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a respiratory medicine atomization inhalation device. Background Art

[0002] Nebulizer therapy uses a nebulizer to separate drugs into tiny liquids, and then delivers the drugs that have become small droplets to the respiratory bronchi and even the alveoli through breathing movements. It can also be used for nasal treatment, and can treat various respiratory diseases. It can clean the airways, humidify the airways and local mucosa, and can also achieve the purpose of local treatment and systemic treatment. Local treatment can mainly be used for the anti-inflammatory, expectorant, and antispasmodic effects of the trachea or local mucosa, and can be absorbed into the blood through the blood vessels of the local mucosa to achieve the effect of systemic treatment. Due to the different drugs used, the effects are not exactly the same. It is often used in clinical practice to treat various respiratory diseases, such as asthma, influenza, common colds, acute rhinitis attacks, and other diseases.

[0003] Medical nebulizers are generally composed of a main unit, an atomizing cup, an atomizing tube, a mouthpiece or an inhalation mask. The main unit can use an ultrasonic generator or a compression pump as a driver. The mouthpiece and the inhalation mask will come into direct contact with the patient's face when in use. In order to prevent cross infection, the mouthpiece and the inhalation mask are usually disposable. However, there is no difference between the existing mouthpieces and inhalation masks before and after use. When conducting group treatment, due to the large number of patients, the number of prepared mouthpieces and inhalation masks is also large. During treatment, medical staff are prone to confuse the used mouthpieces and inhalation masks with the unused mouthpieces and inhalation masks, which is not hygienic and may even cause cross infection. Therefore, a respiratory medicine nebulizer inhalation device is proposed. Summary of the invention

[0004] In view of the fact that there is no difference between the mouthpiece and the inhalation mask before and after use in the prior art, when conducting group treatment, due to the large number of patients, the number of prepared mouthpieces and inhalation masks is also large. During treatment, medical staff may easily confuse the used mouthpiece and inhalation mask with the unused mouthpiece and inhalation mask, which is unhygienic and may even cause cross infection. The purpose of the present invention is to provide a respiratory medicine atomization inhalation device.

[0005] To solve the above problems, the present invention adopts the following technical solutions:.

[0006] A respiratory medicine atomization inhalation device comprises an inhalation piece and an atomization tube, wherein the inhalation piece and the atomization tube are detachably connected via a first connecting tube body and a second connecting tube body, wherein the first connecting tube body is fixedly mounted on the gas delivery end of the atomization tube, and the second connecting tube body is fixedly mounted on the gas delivery end of the inhalation piece, and a baffle and an opening mechanism are arranged on the inner surface of the second connecting tube body, wherein the baffle has toughness;

[0007] A dismantling mechanism is also provided inside the second connecting tube body. Before the first connecting tube body is connected to the second connecting tube body, the opening mechanism makes the barrier part in an expanded state. When the first connecting tube body is connected to the second connecting tube body, the dismantling mechanism replaces the opening mechanism to keep the barrier part in an expanded state. Moreover, after the first connecting tube body is separated from the second connecting tube body, the dismantling mechanism can make the opening mechanism no longer open the barrier part, thereby shrinking the barrier part and blocking the second connecting tube body.

[0008] Optionally, the opening mechanism includes a sleeve, a breakable plate and a slide groove, the sleeve is fixedly sleeved on the outside of the second connecting tube body, a cavity is formed between the inside of the sleeve and the outer surface of the second connecting tube body, the breakable plate is arranged in multiple groups and distributed in the cavity in a circular array, one end of the breakable plate is fixedly connected to the inner surface of the sleeve, and the other end of the breakable plate passes through the side wall of the second connecting tube body and is fixedly connected to the blocking part.

[0009] Optionally, the barrier portion is made of flexible rubber material, surrounds the inner surface of the second connecting tube body and is connected end to end, and both sides of the barrier portion are fixedly connected to the inner surface of the second connecting tube body, and the breakable plate is located in the middle of the barrier portion and is fixedly connected to the barrier portion.

[0010] Optionally, the breakable plate members each include a fixing portion and a connecting portion, a side wall of the second connecting tube body is provided with a sliding groove adapted to the connecting portion, the connecting portion is cooperatively installed inside the sliding groove and forms a moving pair therewith, one end of the fixing portion is fixedly connected to the inner surface of the sleeve, the other end of the fixing portion is fixedly connected to a guide plate and a limiting portion in sequence, the size of the limiting portion is larger than the size of the guide plate, one end of the connecting portion is fixedly connected to the blocking portion, one end of the connecting portion is provided with a guide groove and a limiting groove in sequence, the guide plate is embedded in the guide groove, the limiting portion is embedded in the limiting groove, and the limiting portion is set to be a foam plastic material.

[0011] Optionally, the fixing portion, the connecting portion and the sliding groove are all arranged along the radial direction of the second connecting tube body.

[0012] Optionally, the slide grooves are all located inside the cavity formed by the second connecting pipe body and the sleeve.

[0013] Optionally, the axial cross-section of the second connecting tube body is stepped, and the diameter of the second connecting tube body at the opening is larger than the diameter of the portion where the baffle portion is located.

[0014] Optionally, the outer surface diameter of the first connecting tube body matches the diameter of the opening of the second connecting tube body, and matching thread structures are provided on the outer surface of the first connecting tube body and the inner surface of the second connecting tube body.

[0015] Optionally, the removal mechanism includes a push rod, an annular plate and a spring, the annular plate is arranged at the opening of the second connecting tube body, the push rod is provided in multiple groups, and the push rods correspond to the limiting parts one by one, and the shape of the push rods is adapted to the limiting groove, the inner wall of the second connecting tube body is provided with a groove body adapted to the push rod, and the surface of the push rod is provided with a spring, and when the first connecting tube body is connected to the second connecting tube body, the first connecting tube body causes the push rod to move to one side of the limiting groove.

[0016] Optionally, a groove is provided on the inner wall of the second connecting tube body at a position on the outer surface of the push rod, one end of the spring is fixedly connected to the inner surface of the groove, and the other end of the spring is fixedly connected to the annular plate.

[0017] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0018] In the above scheme, an inhalation mask or a mouthpiece is selected for treatment according to the patient's personal situation. In actual use, the second connecting tube body of the inhalation mask and the mouthpiece are compatible with the first connecting tube body on the nebulizer tube. The first connecting tube body and the second connecting tube body are assembled or disassembled using a threaded structure. When treating different patients, it is only necessary to remove the second connecting tube body from the first connecting tube body and replace it with a new one.

[0019] By arranging a barrier portion inside the second connecting tube body on the surface of the inhalation mask and the mouthpiece, and by arranging an opening mechanism to cooperate with the removal mechanism, the state of the barrier portion changes before and after the nebulization treatment. That is, when the nebulization treatment is finished and the first connecting tube body and the second connecting tube body are removed, the barrier portion can block the second connecting tube body, causing the second connecting tube body to lose its ventilation function, thereby avoiding repeated use of the inhalation mask and the mouthpiece.

[0020] By setting up an opening mechanism and a dismantling mechanism for use together, during the process of connecting the first connecting tube body and the second connecting tube body, that is, during the nebulization treatment process, the push rod replaces the limiting part and is inserted into the limiting groove to limit the connecting part, so that the connecting part keeps pulling the blocking part and makes the blocking part expand. At this time, the ventilation state inside the second connecting tube body is good, which can ensure that the medicine can be inhaled through the second connecting tube body during the nebulization treatment process.

[0038] The following is a detailed description of a respiratory medicine atomization inhalation device provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0039] It should be noted that the references to "one embodiment", "embodiment", "exemplary embodiments", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0040] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0041] It will be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers therebetween, and “on” or “over” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers therebetween.

[0042] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0043] like Figures 1 to 9 As shown, an embodiment of the present invention provides a respiratory medicine atomization inhalation device, including an inhalation piece and an atomization tube, wherein the inhalation piece and the atomization tube are detachably connected through a first connecting tube body 1 and a second connecting tube body 2, wherein the first connecting tube body 1 is fixedly mounted on the gas delivery end of the atomization tube, and the second connecting tube body 2 is fixedly mounted on the gas delivery end of the inhalation piece, and a baffle 3 and an opening mechanism 4 are provided on the inner surface of the second connecting tube body 2, and the baffle 3 has toughness;

[0044] A dismantling mechanism 5 is also provided inside the second connecting tube body 2. Before the first connecting tube body 1 is connected to the second connecting tube body 2, the opening mechanism 4 makes the barrier part 3 in an expanded state. When the first connecting tube body 1 is connected to the second connecting tube body 2, the dismantling mechanism 5 replaces the opening mechanism 4 to keep the barrier part 3 in an expanded state. Moreover, after the first connecting tube body 1 is separated from the second connecting tube body 2, the dismantling mechanism 5 can prevent the opening mechanism 4 from expanding the barrier part 3, thereby shrinking the barrier part 3 and blocking the second connecting tube body 2.

[0045] In actual use, the inhalation device can be an inhalation mask or a mouthpiece. The inhalation mask and the mouthpiece are disposable items and cannot be reused after use. There is no difference between the existing inhalation masks and mouthpieces before and after use. During group treatment, unused inhalation masks and mouthpieces are easily confused with used inhalation masks and mouthpieces, resulting in cross infection.

[0046] like Figure 2 and Figure 3 As shown, the opening mechanism 4 includes a sleeve 41, a breakable plate and a slide groove 48. The sleeve 41 is fixedly sleeved on the outside of the second connecting tube body 2. A cavity is formed between the inside of the sleeve 41 and the outer surface of the second connecting tube body 2. The breakable plate is provided in multiple groups and distributed in the cavity in a circular array. One end of the breakable plate is fixedly connected to the inner surface of the sleeve 41, and the other end of the breakable plate passes through the side wall of the second connecting tube body 2 and is fixedly connected to the blocking portion 3.

[0047] The barrier part 3 is made of flexible rubber material, surrounds the inner surface of the second connecting tube body 2 and is connected end to end, and both sides of the barrier part 3 are fixedly connected to the inner surface of the second connecting tube body 2, and the breakable plate is located in the middle of the barrier part 3 and is fixedly connected to the barrier part 3.

[0048] In this embodiment, before the atomization treatment, the breakable plate is in an unbroken state, and the baffle 3 is in an expanded state due to the traction of the breakable plate. The baffle 3 can actually be made of a rubber material with toughness, and when it is pulled by the breakable plate, the baffle 3 is in an expanded state, so that the second connecting tube body 2 is in a ventilated state; when the breakable plate no longer pulls the baffle 3, the baffle 3 returns to its original state due to its own toughness, blocks the second connecting tube body 2, and makes the second connecting tube body 2 lose its ventilation function.

[0049] like Figure 4 , Figure 5 and Figure 6 As shown, the breakable plate members include a fixing portion 42 and a connecting portion 43. A sliding groove 48 adapted to the connecting portion 43 is provided on the side wall of the second connecting tube body 2. The connecting portion 43 is cooperatively installed inside the sliding groove 48 and forms a moving pair therewith. One end of the fixing portion 42 is fixedly connected to the inner surface of the sleeve 41, and the other end of the fixing portion 42 is fixedly connected to a guide plate 45 and a limiting portion 44 in sequence. The size of the limiting portion 44 is larger than that of the guide plate 45. One end of the connecting portion 43 is fixedly connected to the blocking portion 3, and a guide groove 47 and a limiting groove 46 are provided on one end of the connecting portion 43 in sequence. The guide plate 45 is embedded in the guide groove 47, and the limiting portion 44 is embedded in the limiting groove 46. The limiting portion 44 is set to be made of foam plastic material.

[0050] The fixing portion 42 , the connecting portion 43 and the sliding groove 48 are all arranged along the radial direction of the second connecting pipe body 2 .

[0051] The slide grooves 48 are all located inside the cavity formed by the second connecting pipe body 2 and the sleeve 41 .

[0052] The axial cross section of the second connecting tube body 2 is stepped, and the diameter of the second connecting tube body 2 at the opening is larger than the diameter of the portion where the baffle portion 3 is located.

[0053] The outer surface diameter of the first connecting tube body 1 matches the opening diameter of the second connecting tube body 2 , and the outer surface of the first connecting tube body 1 and the inner surface of the second connecting tube body 2 are provided with matching thread structures.

[0054] In this embodiment, an inhalation mask or a mouthpiece is selected for treatment according to the patient's personal situation. In actual use, the second connecting tube body 2 of the inhalation mask and the mouthpiece are both compatible with the first connecting tube body 1 on the nebulizer tube. The first connecting tube body 1 and the second connecting tube body 2 are assembled or disassembled using a threaded structure. When treating different patients, it is only necessary to remove the second connecting tube body 2 from the first connecting tube body 1 and replace it with a new one. In addition, a corresponding sealing pad can be pasted on the port of the first connecting tube body 1. When the first connecting tube body 1 and the second connecting tube body 2 are connected, the sealing pad can improve the sealing between the first connecting tube body 1 and the second connecting tube body 2 to prevent the leakage of drug mist.

[0055] like Figure 8 and Fig. 9 As shown, the removal mechanism 5 includes a push rod 51, an annular plate 52 and a spring 53. The annular plate 52 is arranged at the opening of the second connecting tube body 2. The push rod 51 is provided in multiple groups, and the push rod 51 corresponds to the limiting portion 44 one by one, and the shape of the push rod 51 is adapted to the limiting groove 46. The inner wall of the second connecting tube body 2 is provided with a groove body adapted to the push rod 51, and the surface of the push rod 51 is provided with a spring 53. When the first connecting tube body 1 is connected to the second connecting tube body 2, the first connecting tube body 1 causes the push rod 51 to move to the side of the limiting groove 46.

[0056] A groove 54 is provided on the inner wall of the second connecting tube body 2 at the position of the outer surface of the push rod 51, one end of the spring 53 is fixedly connected to the inner surface of the groove 54, and the other end of the spring 53 is fixedly connected to the annular plate 52. When the first connecting tube body 1 is connected to the second connecting tube body 2, the spring 53 is compressed by the annular plate 52, and the groove 54 can accommodate the compressed spring 53, so that the first connecting tube body 1, the annular plate 52 and the inner wall of the second connecting tube body 2 are tightly fitted.

[0057] In this embodiment, when the first connecting tube body 1 is screwed into the second connecting tube body 2, the first connecting tube body 1 will push the annular plate 52 and the push rod 51 to move, so that the push rod 51 moves into the limiting groove 46. At this time, the spring 53 is squeezed by the annular plate 52 and becomes compressed. In addition, since the limiting portion 44 inside the limiting groove 46 is made of plastic foam, the limiting portion 44 will be destroyed when the push rod 51 is pushed into the limiting groove 46. Therefore, during the connection between the first connecting tube body 1 and the second connecting tube body 2, that is, during the nebulization treatment, the push rod 51 replaces the limiting portion 44 and is inserted into the limiting groove 46 to limit the connecting portion 43, so that the connecting portion 43 keeps pulling the baffle portion 3, so that the baffle portion 3 is in an expanded state. At this time, the ventilation state inside the second connecting tube body 2 is good, which can ensure that the medicine can be inhaled through the second connecting tube body 2 during the nebulization treatment.

[0058] After the nebulizer treatment is completed, the medical staff unscrews the second connecting tube body 2 from the first connecting tube body 1, and the first connecting tube body 1 no longer squeezes the annular plate 52. The spring 53 compressed on the outer surface of the push rod 51 is restored, driving the annular plate 52 and the push rod 51 to move, so that the push rod 51 moves out from the inside of the limiting groove 46. The push rod 51 no longer restricts the connecting part 43. Since the blocking part 3 itself has toughness, the expanded blocking part 3 is automatically restored to block the inside of the second connecting tube body 2, so that the second connecting tube body 2 loses its ventilation function, thereby avoiding the reuse of the inhalation mask and the mouthpiece.

[0059] The specific working process of the technical solution of the present invention is as follows:

[0060] By arranging a barrier portion 3 inside the second connecting tube body 2 on the surface of the inhalation mask and the mouthpiece, and by arranging an opening mechanism 4 to cooperate with a removal mechanism 5, the state of the barrier portion 3 changes before and after the nebulization treatment, that is, the barrier portion 3 is in an expanded state before and during the connection between the first connecting tube body 1 and the second connecting tube body 2, thereby ensuring that the second connecting tube body 2 can be ventilated during the nebulization treatment.

[0061] In addition, the blocking portion 3 is in a contracted state after the first connecting tube body 1 is separated from the second connecting tube body 2, so that the blocking portion 3 can block the second connecting tube body 2 after the nebulization treatment. The inhalation mask and the mouthpiece lose their ventilation function after one use, thereby avoiding repeated use of the inhalation mask and the mouthpiece. The user can judge whether the inhalation mask and the mouthpiece are in use by the state of the blocking portion 3 to avoid confusion.

[0062] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
