As shown in fig. 1-4, the present application provides an aerosolization system 100 comprising an aerosolization device 10, a drug solution bag 20, a sealing connection 30, and a mouthpiece 40.

As will be understood in conjunction with fig. 5, the atomization device 10 includes an atomization unit 11, a battery cell 12, and a circuit 13.

The atomizing unit 11 is for atomizing a liquid medicine. In this example, the atomizing unit 11 includes an ultrasonic atomizing plate that atomizes the liquid medicine in the micropores of the base body by generating high-frequency vibration by the piezoelectric element to form liquid mist, and the liquid mist is ejected from the micropores to be inhaled by the user. The specific structure of the ultrasonic atomization sheet can refer to the prior art, and is not described herein.

The battery cell 12 supplies power for operating the atomizing unit 11. The cells 12 may be rechargeable cells or disposable cells.

The circuit 13 may control the overall operation of the atomizer unit 11. The circuit 13 controls not only the operation of the cell 12 and the nebulizing unit 11, but also the operation of other elements in the ultrasonic nebulizing system 100. One end of the key K is exposed on the atomizing device 10, and the other end of the key K is electrically connected with the circuit 13; the circuit 13 can receive the instruction of the key K and control the overall operation of the atomizing unit 11.

The atomizer device 10 further comprises a receiving chamber 14 in fluid communication with the atomizer unit 11, wherein a piercing member 15 is arranged in the receiving chamber 14. In this example, the puncturing member 15 is a rotary puncturing member.

And a medicine liquid bag 20 for storing medicine liquid. In a preferred embodiment, the medical fluid bag 20 is a disposable medical fluid bag.

Specifically, as will be understood in conjunction with fig. 6-8, the medical fluid bag 20 includes an encapsulating film 21 and a housing 22.

The housing 22 is substantially cylindrical, and an inner hollow portion forms a reservoir chamber 22a. The volume of the reservoir chamber 22a is 0.25ml to 5ml, so that the liquid medicine stored in the liquid medicine bag 20 is standard quantitative, for example: 0.5ml, 1ml, 2ml, 3ml, 4ml, etc.

The housing 22 has a connection portion (not shown in the drawings) to detachably connect with the atomizing device 10. The connection may be a thread in a screw connection, by means of which a screw connection with the receiving chamber 14 is achieved; of course, snap connections, turn-on connections are also possible. Further, the connection portion may also be a recess or protrusion in a male-female-fit positioning mechanism (similar to the structural design of the pen cap), so that when the medical fluid bag 20 is received in the receiving chamber 14, the insertion information can be fed back.

A groove 22b is formed on the outer surface of the sidewall of the housing 22, and the sealing connector 30 is sleeved on the outer surface of the sidewall of the housing 22 and is partially received in the groove 22 b. Thus, when the medical fluid bag 20 is received in the receiving chamber 14 through the opening a, the sealing joint 30 seals a gap between the inner surface of the receiving chamber 14 and the outer surface of the medical fluid bag 20 to prevent the medical fluid from flowing backward out of the opening a; meanwhile, the liquid medicine bag 20 can be connected with the receiving chamber 14 through the interference fit of the sealing connecting piece 30.

In order to facilitate observation of the liquid medicine stored in the liquid storage cavity 22a, at least part of the top wall 22c of the housing 22 is made of transparent material to form a visible window; thus, the liquid medicine can be observed through the visual window.

When the drug solution package 20 is received in the receiving chamber 14, the top wall 22c of the housing 22 is exposed outside the housing of the aerosolizing device 10, while the rest of the housing 22 is housed within the receiving chamber 14. The top wall 22c of the housing 22 also has a radially extending portion 22d, which radially extending portion 22d constitutes at least part of an extraction site for facilitating extraction of the medicinal fluid bag 20 by a user. As shown in fig. 2, in a preferred embodiment, the end of the opening a is lower than the top wall 22c of the housing 22, so that the part of the housing 22 between the top wall 22c of the housing 22 and the end of the opening a is exposed outside the housing of the atomization device 10, i.e. the radially extending part 22d is exposed outside the opening a; in this manner, the radially extending portion 22d may be easily grasped by the user's fingers and the medical fluid bag 20 removed from the receiving chamber 14.

The top wall 22c of the housing 22 has a portion protruding upward, so that the housing 22 can conform to the shape of the housing of the atomizing device 10, and the appearance is good.

In the present example, the case 22 is not provided with a bottom wall, thereby forming an opening 22e; opening 22e is in fluid communication with reservoir chamber 22a. It is also contemplated that the housing 22 may be provided with a bottom wall, and that it is also possible to form the opening 22e through a through hole in the bottom wall.

The sealing film 21 is bonded to the sidewall of the housing 22 to seal the opening 22e, so as to prevent the liquid medicine stored in the liquid storage chamber 22a from being contaminated. The packaging film 21 is made of a pierceable material such as aluminum foil or tin foil, so that the bottom of the liquid medicine package 20 forms a pierceable portion. When the medicine liquid pack 20 is received in the receiving chamber 14 through the opening a, the piercing member 15 may pierce the bottom of the medicine liquid pack 20; thus, the chemical liquid can flow from the sealed chemical liquid pack 20 into the receiving chamber 14 and further into the atomizing unit 11.

A projection 22f is formed on an inner surface of a side wall of the housing 22, and one end of the projection 22f extends to a bottom end of the housing 22. The projections 22f can function as reinforcing ribs on the one hand; on the other hand, one end of the projection 22f may form an abutting portion, which abuts against one end of the rotary puncturing member 15 when the medicine package 20 is received in the receiving chamber 14 through the opening a, so as to rotate the other end of the rotary puncturing member 15 by a predetermined angle and puncture the bottom of the medicine package 20. The length of the opening 22e of the housing 22 should be greater than the length of the other end of the rotary puncturing member 15 to prevent the rotary puncturing member 15 from being able to puncture the bottom of the medicine bag 20. Typically, the length of the opening 22e is 6.5mm to 20mm.

As will be understood in conjunction with fig. 9, in another preferred embodiment, the front view of the housing 22 projected onto the basic projection plane is a left-right symmetrical figure, and the dotted line in the figure is the symmetry axis of the front view. In this way, after rotating the liquid medicine package 20 horizontally by 180 °, it can also be removably received in the receiving chamber 14 through the opening a; namely, the atomization device 10 can be inserted without dividing into the left and right direction.

The cross-section of the housing 22 is one of circular, oval, racetrack-ring, square, or rectangular. The present example preferably takes the form of an oval. The projection 22f may be disposed on one side of the oval shape and the opening 22e may be disposed on the other side of the oval shape. In a preferred embodiment, the housing 22 is symmetrically provided with protrusions 22f (located on the major axis of the ellipse) at both sides in the horizontal direction; thus, the liquid medicine package 20 can be inserted into the atomizing device 10 without being separated in the left-right direction, and after the liquid medicine package 20 is horizontally rotated by 180 °, one end of each of the projections 22f on both sides can be brought into contact with one end of the rotary piercing member 15.

The mouthpiece 40 is installed at the opening B of the atomizing device 10, and an airflow inlet is provided on the mouthpiece 40. Thus, when the liquid medicine package 20 is received in the receiving chamber 14 through the opening a, the user can operate the key K, so that the circuit 13 controls the atomizing unit 11 to start atomizing, and the liquid mist formed by atomizing is ejected from the opening B of the atomizing device 10, mixed with the gas flowing in from the gas flow inlet of the mouthpiece 40, and ejected from the mouth end of the mouthpiece 40, so as to be inhaled by the user (indicated by the dashed arrow in fig. 3).

It will be appreciated that the mouthpiece 40 may be replaced by other fittings, such as: a mask, etc.
