[0030] In order to make the technical solution of the present invention better understood by the technical personnel in the field, and to make the above-mentioned features, purposes and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the embodiments. The embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1-4 As shown, the present invention includes:

[0032] An atomizing sheet installed in the connecting shell (1), a flexible drug storage bag (2) located in the drug storage cavity of the connecting shell (1), and an elastic body (3), the bag cavity of the flexible drug storage bag (2) being connected to the atomizing sheet, and a drug injection port (11) being provided in the flexible drug storage bag (2);

[0033] The elastic body (3) deforms and rebounds to squeeze the flexible medicine storage bag (2), so as to maintain the liquid pressure of the medicine in the flexible medicine storage bag (2) at 1-28 cmH2O;

[0034] A water-blocking and air-permeable structure is arranged adjacent to one side of the atomizing sheet corresponding to the flexible drug storage bag (2) to discharge gas during the atomization process;

[0035] The distance between the water-blocking and air-permeable structure and the atomizing sheet is less than 2 mm, and the two form an atomizing chamber.

[0036] Before use, an appropriate amount of uniform atomized liquid medicine needs to be injected into the flexible drug storage bag (2) through the drug injection port (11), and the atomized liquid medicine will fill the flexible drug storage bag (2) and the infusion pipeline from the flexible drug storage bag (2) to the atomization cavity. Simultaneously, the air filled in the flexible drug storage bag (2) and the infusion pipeline will be squeezed into the atomization cavity, and finally gradually discharged from the water-blocking and air-permeable structure, and the atomization cavity will be slowly infiltrated by the liquid medicine.

[0037] During atomization, the atomization drug outlet of the connecting shell (1) is connected to the patient's breathing circuit, the atomizing sheet is connected to an external power source and started, and the drug liquid in the atomizing chamber is atomized by the atomizing sheet and enters the patient's breathing circuit through the atomizing outlet. At the same time, the flexible drug storage bag (2) contracts under the rebound and compression of the elastic body (3), and the drug liquid in the flexible drug storage bag (2) is continuously replenished into the atomizing chamber.

[0038] In order to maintain the efficient and continuous operation of the atomizer, the liquid pressure needs to be maintained at 1-28cmH2O to prevent excessive pressure from causing the atomizer to malfunction. In order to maintain the stability of the atomizer chamber, that is, the continuous removal of gas, the distance between the water-blocking and breathable structure and the atomizer needs to be less than 2mm

[0039] During the mixing and injection stage, some air will be dissolved in the drug solution, and some air will also remain in the flexible drug storage bag (2). In order to minimize the impact of the air, the flexible drug storage bag (2) partially or completely adopts a water-blocking breathable membrane, and the air is squeezed out of the flexible drug storage bag (2) by the rebound extrusion of the elastomer (3).

[0040] The structure of the connecting shell (1) is as follows: the connecting shell (1) is divided into a connecting end (13) and a drug storage end (14), one end of the connecting end (13) is provided with an atomizing drug outlet, and the other end is fixedly connected to the drug storage end (14), and a sealing ring (16) is provided at the connection to fix the atomizing sheet. The connecting end (13) is connected to the patient's breathing circuit through the atomizing drug outlet, and the drug storage end (14) is used to place a flexible drug storage bag (2) to store liquid medicine. The atomizing sheet adopts an atomizing sheet, and sealing rings are provided on the upper and lower sides. The atomizing sheet is connected to an external power supply through the power port on the side wall.

[0041] refer to Figure 5 The specific structure of the flexible medicine storage bag (2) is as follows: the flexible medicine storage bag (2) is formed by an upper soft film (21) and a lower soft film (22) connected by edges, and the upper soft film (21) and / or the lower soft film (22) are made of a polymer microporous waterproof material for discharging internal gas;

[0042] A medicine passage hole (23) is arranged at the top of the flexible medicine storage bag (2), and a bonding area (24) is arranged around the medicine passage hole (23). The medicine passage hole (23) is connected to the atomizing sheet through a medicine liquid channel arranged in the connecting shell (1).

[0043] The bonding area (24) is used to bond and fix with the connection shell (1), so as to connect and fix the medicine hole (23) with the infusion pipeline in the connection shell (1). The medicine hole (23) is slightly larger than the radius of the infusion pipeline port to meet the injection of the medicine solution.

[0044] An adjusting body (16) for adjusting the position of the elastic body (3) is arranged near the elastic body (3) in the medicine storage cavity, and the adjusting body (16) and the connecting shell (1) can be temporarily fixed. Since the surface of the flexible medicine storage bag (2) is in an arc shape, in order to better promote the elastic body (3) and the flexible medicine storage bag (2) to abut against each other, an adjusting body (16) is also arranged, and the adjusting body (16) is connected to the inside of the medicine storage cavity through a thread, and the advancing and retreating of the adjusting body (16) is determined by the thread to adjust the pressure of the elastic body (3) on the flexible medicine storage bag (2).

[0045] In order to maintain the pressure in the flexible drug storage bag (2), the pressure of the elastic body (3) on the flexible drug storage bag (2) is 2-18N, and the maximum volume of the flexible drug storage bag (2) is less than 20ml. In order to ensure that the elastic body (3) has a stable pressure on the drug liquid in the flexible drug storage bag (2), the generally used available volume is 5-15ml. In this embodiment, the elastic body (3) is made of elastic cotton.

[0046] In order to facilitate exhaust during the atomization process, a plurality of exhaust channels are connected and arranged on the side of the water-blocking and breathable structure away from the atomizing sheet, and the water-blocking and breathable structure adopts a water-blocking and breathable membrane.

[0047] In order to facilitate the reuse of the connection shell (1), the connection shell (1) is connected to the atomization chamber to provide a flushing outlet, and a blocking body is arranged on the outside of the flushing outlet. When in use, the blocking body blocks the flushing outlet; when cleaning, a cleaning liquid, such as clean water, is injected through the injection port for cleaning.

[0048] The above embodiments are merely illustrative of the principles and effects of this patent application, and are not intended to limit this patent application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
