[0002] The blood-brain barrier is a natural barrier between the body circulation and the central nervous system, which hinders many drugs from entering the central nervous system to play a therapeutic role while playing a barrier role. Traditional drug delivery methods, such as intracranial injection and subarachnoid injection, are difficult to be widely used in clinical patients due to strong trauma and high operation technical requirements.

[0003] A large number of clinical studies have found that the nasal olfactory region is a location where nerve cells are in direct contact with the surrounding environment, which makes it possible for drugs to bypass the blood-brain barrier and enter the brain through the nasal cavity. Although the existing nasal drug delivery technology has been widely used, the existing nasal drug delivery device needs to invade the nasal cavity or cannot achieve true deep drug delivery. SUMMARY

[0004] The present application provides a high-pressure air capsule, a spray device comprising the same and a spray assembly, which can drive the reagent to form a high-speed linear jet flow by high-pressure air to achieve deep drug delivery directly to the target area such as the olfactory region, and does not need to invade the human body such as the nasal cavity during drug delivery, which is safe and sanitary.

[0037] With reference to Figures 1 to 6 The embodiments of the present application provide a high-pressure air capsule 100 and a spray device 10 and a spray assembly 20 comprising the same.

[0038] Specifically, the high-pressure air capsule 100 provided by the embodiments of the present application comprises a capsule shell 110, a first cavity 120 located in the capsule shell 110 and adapted to contain a reagent, a second cavity 130 located in the capsule shell 110 and adapted to contain high-pressure air, a connecting passage 141, 142 located in the capsule shell 110 and adapted to communicate the first cavity 120 and the second cavity 130, and a movable valve 151, 152 at least partially disposed in the capsule shell 110 and adapted to open or close the connecting passage 141, 142.

[0039] In specific implementations, the first cavity 120 is provided with a nozzle 121 communicating with the outside of the capsule shell 110. The movable valve 151, 152 is adapted to be driven to move by an external force applied from the outside of the capsule shell 110 to open the connecting passage 141, 142 so that the high-pressure air from the second cavity 130 enters the first cavity 120, thereby driving the reagent in the first cavity 120 to be sprayed out of the nozzle 121 in the form of a linear jet.

[0040] In specific implementations, the capsule shell 110 has elasticity at the portion thereof connected with the movable valve 151, 152.

[0041] Specifically, the capsule shell 110 can include a mounting portion adapted to mount the movable valve 151, 152. The mounting portion is used to fix the movable valve 151, 152 and has elasticity, which is adapted to be driven to elastically deform by an external force applied from the outside of the capsule shell 110, and adapted to restore the elastic deformation to drive the movable valve 151, 152 to move reversely to close the connecting passage 141, 142 when the external force is removed.

[0042] With reference to Figure 2 In some embodiments, the movable valve 151, 152 can include a first movable valve 151. The mounting portion can include a first mounting portion having an elastic deformation capability. The first movable valve 151 passes through the first mounting portion so that one end 151a thereof is exposed to the outside of the capsule shell 110 and the other end 151b thereof is located in the inside of the capsule shell 110.

[0043] In some embodiments, the first movable valve 151 can be made of an elastic material and integrally formed with the first mounting portion.

[0044] In a specific implementation, the other end 151b of the first movable valve 151 located inside the capsule housing 110 is adapted to close the connecting passages 141, 142 between the first cavity 120 and the second cavity 130. For example, the other end 151b of the first movable valve 151 can be located inside the connecting passages 141, 142 to close the connecting passages 141, 142.

[0045] In some embodiments, the connecting passages 141, 142 can include a first connecting passage 141. The inner diameter of the first connecting passage 141 can gradually decrease in a direction of the first movable valve 151 pointing to the first cavity 120. The other end 151b of the first movable valve 151 can adopt a spherical structure and is adapted to be embedded into the first connecting passage 141 in the direction of the first movable valve 151 pointing to the first cavity 120 to close the first connecting passage 141.

[0046] Correspondingly, an acting force applied to the first movable valve 151 from outside the capsule housing 110 can extend in a direction away from the first connecting passage 141. Since one end 151a of the first movable valve 151 is exposed outside the capsule housing 110, the one end 151a of the first movable valve 151 is adapted to be applied with the acting force from outside the capsule housing 110. When the one end 151a of the first movable valve 151 is applied with the acting force, it can move in the direction away from the first connecting passage 141 under the driving of the acting force and bring the other end 151b of the first movable valve 151 to move in the direction away from the first connecting passage 141. When the other end 151b of the first movable valve 151 moves away from the first connecting passage 141 in the direction away from the first connecting passage 141, it can move out of the first connecting passage 141 to make the first cavity 120 and the second cavity 130 conduct through the first connecting passage 141.

[0047] Since the first mounting portion is fixedly connected with the first movable valve 151 and has elasticity, when the first movable valve 151 is applied with the acting force to move in the direction away from the first connecting passage 141, the first mounting portion will generate a deformation extending in the direction away from the first connecting passage 141.

[0048] When the acting force applied to the one end 151a of the first movable valve 151 from outside the capsule housing 110 is removed, the first mounting portion will restore the elastic deformation and bring the first movable valve 151 to move reversely, thereby making the other end 151b of the first movable valve 151 move in the direction towards the first connecting passage 141 to embed into and close the first connecting passage 141.

[0049] Reference Figure 3In other embodiments, the movable valve 151, 152 can include a second movable valve 152. The mounting portion can include a second mounting portion having elastic deformation capability. The second movable valve 152 is located within the capsule housing 110, and one end 152a thereof is fixed to the second mounting portion.

[0050] In some embodiments, the second mounting portion can be made of elastic material, and is integrally formed with the capsule housing 110.

[0051] In specific implementations, the other end 152b of the second movable valve 152 is adapted to close the connecting passages 141, 142 between the first cavity 120 and the second cavity 130. For example, the other end 152b of the second movable valve 152 can be located within the connecting passages 141, 142 to close the connecting passages 141, 142.

[0052] In some embodiments, the connecting passages 141, 142 can include a second connecting passage 142. The second connecting passage 142 has an inner diameter at one end thereof that is smaller than an inner diameter at the other end thereof that communicates with the second cavity 130. Accordingly, the other end 152b of the second movable valve 152 can have a spherical structure, and has an outer diameter that matches the other end of the second connecting passage 142. The other end 152b of the second movable valve 152 can be embedded in the other end of the second connecting passage 142 to close the second connecting passage 142. Meanwhile, the second movable valve 152 can have a rod structure at a portion thereof other than the spherical structure, and the rod structure has a diameter that is smaller than the diameter of the spherical structure. The diameter of the rod structure is smaller than or equal to the inner diameter of the one end of the second connecting passage 142. The rod structure can be installed and fixed to the second mounting portion through the one end of the second connecting passage 142.

[0053] In specific implementations, an external force applied to the second mounting portion from the outside of the capsule housing 110 can extend in a direction toward the second connecting passage 142. When the second mounting portion is subjected to the external force from the outside of the capsule housing 110, the second mounting portion can generate elastic deformation in the direction toward the second connecting passage 142 under the driving of the external force, and move the one end 152a of the second movable valve 152 in the direction toward the second connecting passage 142, and further move the other end 152b of the second movable valve 152 in the direction toward the second cavity 130 that communicates with the second connecting passage 142. When the other end 152b of the second movable valve 152 moves in the direction toward the second cavity 130, it can move out of the second connecting passage 142 and into the second cavity 130, thereby connecting the first cavity 120 and the second cavity 130 through the second connecting passage 142.

[0054] When the force applied to the second mounting portion is removed, the second mounting portion will recover the elastic deformation, and drive the second movable valve 152 to move reversely, and then drive the other end 152b of the second movable valve 152 to return to the second connecting passage 142 to close the second connecting passage 142.

[0055] When the first cavity 120 and the second cavity 130 are communicated through the connecting passages 141, 142, the high-pressure air in the second cavity 130 can enter the first cavity 120 from the second cavity 130, so as to drive the reagent in the first cavity 120 to be sprayed from the nozzle 121 in a linear jet manner.

[0056] In some embodiments, the reagent can include a powder reagent. In this case, the linear jet sprayed from the nozzle 121 can include a powder jet.

[0057] In other embodiments, the reagent can also include a liquid reagent. In this case, the linear jet sprayed from the nozzle 121 can include a liquid jet.

[0058] It can be understood that in specific implementations, the particle size of the liquid or powder in the linear jet can also be controlled by controlling the pressure of the high-pressure air and / or the caliber of the nozzle 121.

[0059] In some embodiments, the liquid jet can include a liquid jet in an atomized state, which has the same or similar particle size as that of the reagent after being atomized. In this way, the reagent can have a spraying effect after being sprayed.

[0060] In other embodiments, the liquid jet can include a liquid jet in a non-atomized state, which has a larger particle size than that of the liquid jet in the atomized state. In this way, the reagent can have a longer range after being sprayed, so that the reagent supply at a longer distance can be better achieved, i.e., the deep drug delivery can be better achieved.

[0061] In some embodiments, the first cavity 120 also has a first cavity opening in communication with the outside and a cover 122 arranged at the first cavity opening. The nozzle 121 can be arranged at the cover 122.

[0062] In specific implementations, the first cavity 120 and the second cavity 130 can be communicated, and air can be delivered into the first cavity 120 through the first cavity opening, so as to deliver the air into the second cavity 130 and form high-pressure air in the second cavity 130. When the high-pressure air is formed in the second cavity 130, the first cavity 120 and the second cavity 130 can be closed by the movable valves 151, 152, so as to seal the high-pressure air in the second cavity 130.

[0063] When the second cavity 130 is filled with high-pressure air, the reagent can be delivered into the first cavity 120 through the first cavity opening, and the first cavity opening can be closed by the cover 122 after the delivery of the reagent is completed.

[0064] In some embodiments, the second cavity 130 can be filled with high-pressure air other than air.

[0065] In some embodiments, the nozzle 121 of the cover 122 has a very small caliber, which is not enough to leak the reagent out of the capsule shell 110 without the driving of the high-pressure air.

[0066] In some embodiments, the high-pressure air capsule 100 can be a disposable capsule. In this case, the high-pressure air from the second cavity 130 into the first cavity 120 is suitable for spraying the reagent in the first cavity 120 out completely at one time.

[0067] With reference to Figures 1 to 3 The present application also provides a reagent spraying device 10.

[0068] In particular, the reagent spraying device 10 can include a device shell 200, a high-pressure air capsule 100 located in the device shell 200, and a trigger mechanism 300 fixed in the device shell 200.

[0069] In some embodiments, one end of the trigger mechanism 300 is suitable for being pressed to drive the other end of the trigger mechanism 300 to apply a force to the high-pressure air capsule 100.

[0070] In some embodiments, the device shell 200 can also include a device opening, and one end of the trigger mechanism 300 is suitable for being exposed outside the device shell 200 through the device opening, so as to be pressed from the outside of the device shell 200.

[0071] In some embodiments, the trigger mechanism 300 can include a support 310 fixed in the device shell 200 and a movable piece 320 rotationally connected to the support 310.

[0072] In some embodiments, one end 321 of the movable piece 320 is exposed outside the device shell 200 through the device opening, and is suitable for being pressed to drive the other end 322 of the movable piece 320 to rotate around the support 310 to apply a force to the high-pressure air capsule 100.

[0073] In some embodiments, one end 321 of the movable piece 320 is suitable for being pressed to drive the other end 322 of the movable piece 320 to rotate in a direction away from the first connecting channel 141, so as to apply a force extending in the direction away from the first connecting channel 141 to one end 151a of the first movable valve 151.

[0074] In some embodiments, the end 321 of the active member 320 is further adapted to be pressed to drive the other end 322 of the active member 320 to rotate in the direction towards the second connecting passage 142, so as to apply an action force in the direction towards the second connecting passage 142 to the end 152a of the second active valve 152.

[0075] In the embodiments of the present application, the trigger mechanism 300 can be implemented by any known conventional technical means in the prior art, in addition to the above-mentioned implementation manners, which are not limited herein.

[0076] In the specific implementation, the device housing 200 comprises a capsule cavity 210 and a taking and placing opening 220 which communicates the capsule cavity 210 with the outside. The high-pressure air capsule 100 is loaded into or taken out of the capsule cavity 210 through the taking and placing opening 220.

[0077] In some embodiments, the high-pressure air capsule 100 is adapted to be in interference fit with the capsule cavity 210 when being loaded into the capsule cavity 210.

[0078] With reference to Figures 4 to 6 The embodiments of the present application further provide a spray assembly 20.

[0079] Specifically, the spray assembly 20 can comprise at least two spray devices 10 which are detachably connected together.

[0080] In some embodiments, the spray assembly 20 can comprise two spray devices 10 which are detachably connected together.

[0081] Specifically, the spray assembly 20 can comprise a first spray device 21 and a second spray device 22 which are detachably connected together. The first spray device 21 and the second spray device 22 both adopt the spray device 10 provided by the embodiments of the present application.

[0082] The first spray device 21 can comprise a first device housing 211, a first opening 212 of the first device housing 211, and a first trigger mechanism 213 which is fixed in the first device housing 211 and is partially exposed outside the first device housing 211 through the first opening 212. The first device housing 211 can be the device housing 200 of the spray device 10. The first opening 212 can be the device opening of the spray device 10.

The second device housing 221 can be the device housing 200 of the spray device 10. The second opening 222 can be the device opening of the spray device 10.

In this way, not only the combination and storage of the two spray devices 10 are facilitated, but also the space is saved.

[0085] In some embodiments, the first spray device 21 and the second spray device 22 can be magnetically connected.

[0086] Specifically, the first spray device 21 can be provided with a first magnet 214 at a position close to the first opening 212, and the second spray device 22 can be provided with a second magnet 224 at a position close to the second opening 222.
