[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 pipe body is stepped, and the diameter of the opening of the second connecting pipe body is larger than the diameter of the part where the partition is located.

[0014] Optionally, the outer surface diameter of the first connecting pipe body is adapted to the diameter of the opening of the second connecting pipe body, and a matching thread structure is provided on the outer surface of the first connecting pipe body and the inner surface of the second connecting pipe body.

[0015] Optionally, the disassembly mechanism includes a push rod, an annular plate and a spring. The annular plate is arranged at the opening of the second connecting pipe body. There are multiple groups of push rods, and the push rods correspond to the limiting parts one by one. The shape of the push rod is adapted to the limiting groove. A groove adapted to the push rod is opened on the inner wall of the second connecting pipe body. Springs are sleeved on the surfaces of the push rods. When the first connecting pipe body is connected to the second connecting pipe body, the first connecting pipe body moves the push rod towards the limiting groove side.

[0016] Optionally, grooves are opened on the inner wall of the second connecting pipe body at the positions of the outer surfaces of the push rods. 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] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0018] In the above solution, an inhalation mask or a mouthpiece is selected for treatment according to the individual situation of the patient. During actual use, the second connecting pipe bodies of the inhalation mask and the mouthpiece are both adapted to the first connecting pipe body on the atomizing cylinder. The first connecting pipe body and the second connecting pipe body are assembled or disassembled by a thread structure. When different patients are treated, only the second connecting pipe body needs to be disassembled from the first connecting pipe body and then replaced with a new one.

[0019] By arranging a partition in the second connecting pipe body on the surfaces of the inhalation mask and the mouthpiece, and by setting the opening mechanism and the disassembly mechanism to cooperate, the state of the partition changes before and after atomization treatment. That is, when the atomization treatment ends and the first connecting pipe body and the second connecting pipe body are disassembled, the partition can block the second connecting pipe body, causing the second connecting pipe body to lose its ventilation function, thereby avoiding the repeated use of the inhalation mask and the mouthpiece.

[0020] By setting the opening mechanism and the disassembly mechanism to cooperate, during the connection process of the first connecting pipe body and the second connecting pipe body, that is, during the atomization treatment process, the push rod replaces the limiting part and is inserted into the limiting groove to play a limiting role on the connecting part, so that the connecting part keeps pulling the partition, making the partition in an expanded state. At this time, the ventilation state inside the second connecting pipe body is good, and it can ensure that during the atomization treatment process, the drug can be inhaled through the second connecting pipe body.

[0043] As Figures 1 to 9 shown, an embodiment of the present invention provides a respiratory medicine atomization inhalation device, including an inhalation part and an atomization cylinder. The inhalation part and the atomization cylinder are detachably connected through a first connecting pipe body 1 and a second connecting pipe body 2. The first connecting pipe body 1 is fixedly installed at the air delivery end of the atomization cylinder, and the second connecting pipe body 2 is fixedly installed at the air delivery end of the inhalation part. A partition part 3 and an opening mechanism 4 are arranged on the inner surface of the second connecting pipe body 2, and the partition part 3 has toughness;

[0044] A disassembly mechanism 5 is further arranged inside the second connecting pipe body 2. Before the first connecting pipe body 1 and the second connecting pipe body 2 are connected, the opening mechanism 4 makes the partition part 3 in an expanded state. When the first connecting pipe body 1 and the second connecting pipe body 2 are connected, the disassembly mechanism 5 replaces the opening mechanism 4 to keep the partition part 3 in an expanded state, and the disassembly mechanism 5 can make the opening mechanism 4 no longer push open the partition part 3 after the first connecting pipe body 1 and the second connecting pipe body 2 are separated, so that the partition part 3 shrinks to block the second connecting pipe body 2.

[0045] During actual use, the inhalation part can be an inhalation mask or a mouthpiece. The inhalation mask and the mouthpiece are disposable items and cannot be used again after use. The existing inhalation masks and mouthpieces have no difference before and after use. During group treatment, the unused inhalation masks and mouthpieces are likely to be confused with the used inhalation masks and mouthpieces, resulting in cross-infection.

[0046] As Figure 2 and Figure 3 shown, the opening mechanism 4 includes a sleeve 41, a breakable plate member, and a chute 48. The sleeve 41 is fixedly sleeved outside the second connecting pipe body 2. A cavity is formed between the inside of the sleeve 41 and the outer surface of the second connecting pipe body 2. Multiple groups of breakable plate members are arranged in a circular array in the cavity. One end of the breakable plate member is fixedly connected to the inner surface of the sleeve 41, and the other end of the breakable plate member penetrates the side wall of the second connecting pipe body 2 and is fixedly connected to the partition part 3.

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

[0048] In this embodiment, before atomization treatment, the breakable plate member is in an unbroken state. Under the traction of the breakable plate member, the partition portion 3 is in an expanded state. The partition portion 3 can actually be made of a rubber material with toughness. When being tractioned by the breakable plate, the partition portion 3 is in an expanded state, making the second connecting pipe body 2 in a ventilation state; when the breakable plate no longer tractiones the partition portion 3, the partition portion 3 returns to its original state under the action of its own toughness, blocking the second connecting pipe body 2 and causing the second connecting pipe body 2 to lose its ventilation function.

[0049] As Figure 4 、 Figure 5 and Figure 6 shown, the breakable plate member includes 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 pipe body 2. The connecting portion 43 is fitted and installed inside the sliding groove 48 and forms a moving pair with it. 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 with 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 partition portion 3. A guide groove 47 and a limiting groove 46 are provided at one end of the connecting portion 43 in sequence. The guide plate 45 is embedded inside the guide groove 47, and the limiting portion 44 is embedded inside the limiting groove 46. The limiting portion 44 is 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 sliding 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 pipe body 2 is stepped, and the diameter of the opening of the second connecting pipe body 2 is larger than the diameter of the part where the partition portion 3 is located.

[0053] The outer surface diameter of the first connecting pipe body 1 is adapted to the diameter of the opening of the second connecting pipe body 2, and a matching thread structure is provided on the outer surface of the first connecting pipe body 1 and the inner surface of the second connecting pipe body 2.

[0054] In this embodiment, an inhalation mask or a mouthpiece is selected for treatment according to the patient's personal situation. During actual use, the second connecting pipe body 2 of both the inhalation mask and the mouthpiece is adapted to the first connecting pipe body 1 on the atomizing cylinder. The first connecting pipe body 1 and the second connecting pipe body 2 are assembled or disassembled using a threaded structure. When different patients are being treated, they only need to disassemble the second connecting pipe body 2 from the first connecting pipe body 1 and then replace it with a new one. Additionally, a corresponding sealing gasket can be adhered to the port of the first connecting pipe body 1. When the first connecting pipe body 1 and the second connecting pipe body 2 are connected, the sealing gasket can improve the sealing performance between the first connecting pipe body 1 and the second connecting pipe body 2 and prevent the leakage of the medicinal mist.

[0055] As Figure 8 and Figure 9 shown, the disassembly 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 pipe body 2. There are multiple groups of the push rods 51, and the push rods 51 correspond to the limiting parts 44 one by one. The shape of the push rod 51 is adapted to the limiting groove 46. A groove adapted to the push rod 51 is provided on the inner wall of the second connecting pipe body 2. Springs 53 are sleeved on the surfaces of the push rods 51. When the first connecting pipe body 1 and the second connecting pipe body 2 are connected, the first connecting pipe body 1 causes the push rod 51 to move towards the limiting groove 46.

[0056] Grooves 54 are provided on the inner wall of the second connecting pipe body 2 at positions outside the outer surfaces of the push rods 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 pipe body 1 and the second connecting pipe body 2 are connected, 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 pipe body 1, the annular plate 52, and the inner wall of the second connecting pipe body 2 are closely attached.

[0057] In this embodiment, when the first connecting pipe body 1 is screwed into the second connecting pipe body 2, the first connecting pipe body 1 will push the annular plate 52 and the push rod 51 to move, causing the push rod 51 to move into the limiting groove 46. At this time, the spring 53 is compressed under the extrusion of the annular plate 52. Additionally, since the limiting part 44 inside the limiting groove 46 is made of plastic foam, during the process of the push rod 51 being pushed into the limiting groove 46, the limiting part 44 will be damaged. Therefore, during the connection process of the first connecting pipe body 1 and the second connecting pipe body 2, that is, during the atomization treatment process, the push rod 51 replaces the limiting part 44 and is inserted into the limiting groove 46 to play a limiting role on the connecting part 43, so that the connecting part 43 keeps pulling the partition part 3, making the partition part 3 in an expanded state. At this time, the ventilation state inside the second connecting pipe body 2 is good, which can ensure that during the atomization treatment process, the medicine can be inhaled through the second connecting pipe body 2.

[0058] After the atomization treatment is over, the medical staff unscrew the second connecting pipe body 2 from the first connecting pipe body 1. The first connecting pipe body 1 no longer presses the annular plate 52, and the spring 53 compressed on the outer surface of the push rod 51 thus returns to its original state, driving the annular plate 52 and the push rod 51 to move, so that the push rod 51 moves out of the limiting groove 46. The push rod 51 thus no longer restricts the connecting portion 43. Since the partition portion 3 itself has toughness, the expanded partition portion 3 automatically returns to its original state and seals the inside of the second connecting pipe body 2, causing the second connecting pipe body 2 to lose 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 partition portion 3 inside the second connecting pipe body 2 on the surfaces of the inhalation mask and the mouthpiece, and by arranging an opening mechanism 4 and a disassembly mechanism 5 to cooperate, the state of the partition portion 3 changes before and after the atomization treatment, that is, the partition portion 3 is in an expanded state both before and when the first connecting pipe body 1 is connected to the second connecting pipe body 2, so as to ensure that the second connecting pipe body 2 can be ventilated during the atomization treatment.

[0061] In addition, the partition portion 3 is in a contracted state after the first connecting pipe body 1 is separated from the second connecting pipe body 2, so that the partition portion 3 can seal the second connecting pipe body 2 after the atomization treatment. The inhalation mask and the mouthpiece lose their ventilation function after one use, avoiding the reuse of the inhalation mask and the mouthpiece, and the user can judge whether the inhalation mask and the mouthpiece have been used through the state of the partition portion 3, avoiding confusion.

[0062] The present invention covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, elements and circuits are not described in detail.

[0063] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
