Description

Technical Field

[0001] The utility model relates to an aerosol jet device, in particular to a medicinal inhalable aerosol jet device for helping to complete respiratory drug administration during drug jetting. Background Art

[0002] Compared with subcutaneous injection, respiratory drug administration has the advantages of fast onset of action, less toxicity accumulation and side effects on the human body, and is more friendly to the patient's body. As a common respiratory drug administration method, inhaled aerosol usually needs to be used in conjunction with special equipment, such as a nebulizer, a ventilator, etc. These devices are bulky and difficult to carry around, which makes it necessary for patients to stay in a designated area for the use of aerosol, and the use process is rather inconvenient.

[0003] Some portable devices have been developed for existing inhaled aerosol to avoid the inconvenience brought by special equipment to the use process. In particular, a medicine-taking component part and a nebulizing nozzle device are connected by a hose. During drug administration, a medical staff removes the medicine-taking component part connected to the hose to take medicine from the liquid medicine. After obtaining a certain dose of medicine, the medicine-taking component is reconnected to the hose. At this time, the nebulizing nozzle device at the other end of the hose is placed in the patient's mouth. Through the operation of the medical staff on the medicine-taking component, the liquid medicine flows through the hose and finally becomes fine aerosol due to the chip structure in the nebulizing nozzle and is released at the patient's oral cavity and throat position for respiratory drug administration.

[0004] However, due to the existence of a long-distance hose in the above-mentioned inhaled aerosol device, the liquid medicine may remain in the hose, ultimately resulting in inaccurate drug administration dose. And the connection between the medicine-taking component and the hose adopts a simple plug-and-play method, which may cause the possibility of detachment between the medicine-taking component and the hose during use due to reasons such as high internal pressure. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a medicinal inhalable aerosol jet device with accurate and reliable drug administration process for the above problems.

[0006] A medicinal inhalable aerosol jet device includes: a medicine-taking component, a sealing ring and an aerosol jet component, wherein: the aerosol jet component has two ports, namely a drug administration port and a mouthpiece port, and the aerosol jet component further includes a liquid medicine conversion component, through which the liquid medicine in the medicine-taking component can be atomized. Further, through the drug administration port, the medicine-taking component can be assembled with the aerosol jet component in a horizontal or vertical direction, and the sealing ring is arranged on the contact surface when the medicine-taking component and the aerosol jet component are assembled.

[0007] Preferably, the sealing ring is made of a rubber elastomer selected from the following: butyl rubber, neoprene, nitrile rubber, ethylene propylene diene monomer rubber, and the remaining main types of rubber.

[0008] Furthermore, the aerosol jet assembly is provided with ventilation holes around the liquid medicine conversion assembly.

[0009] Preferably, the ventilation holes are symmetrically distributed in a crescent shape around the liquid medicine conversion assembly.

[0010] Preferably, the ventilation holes are evenly distributed in an arc around the liquid medicine conversion assembly in a circular pattern.

Detailed implementation manners

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0031] Figures 1 to 5 A preferred embodiment of the medicated inhalable aerosol jet device of the present invention is shown. In this preferred embodiment, the medicated inhalable aerosol jet device includes a medicine-taking assembly 1, a sealing ring 2, and an aerosol jet assembly 3. The sealing ring 2 is disposed between the medicine-taking assembly 1 and the aerosol jet assembly 3, and the aerosol jet assembly 3 is in an L shape.

[0032] Such as Figures 2 - 3As shown, the aerosol jet assembly 3 has two ports in the vertical and horizontal directions, namely the drug delivery end 304 and the mouthpiece end 305. Among them, the drug delivery end 304 is a vertical port, and the drug taking assembly 1 can be assembled with the aerosol jet assembly 3 in the vertical direction through the drug delivery end 304. The mouthpiece end 305 is a horizontal port. During the use of the overall device, the patient needs to put the mouthpiece end 305 into the mouth. The aerosol jet assembly 3 contains a liquid medicine conversion assembly 4. The placement direction of the liquid medicine conversion assembly 4 is the same as that of the mouthpiece end 305. The liquid medicine in the drug taking assembly 1 is converted into an aerosol form through the liquid medicine conversion assembly 4 and finally sprayed into the patient's oral cavity from the mouthpiece end 305. A plurality of ventilation holes 302 are arranged around the liquid medicine conversion assembly 4, enabling the patient to inhale when the aerosol converted from the liquid medicine enters the oral cavity, facilitating the entry of drug components into the patient's respiratory tract. The drug taking assembly 1 and the aerosol jet assembly 3 are fixed by snap fitting to prevent the drug taking assembly 1 from detaching from the aerosol jet assembly 3 during drug delivery. A viewing window 303 is also provided on the aerosol jet assembly 3. Through the viewing window 303, the remaining amount of the liquid medicine in the drug taking assembly 1 can be observed, facilitating the operator to evaluate the drug delivery amount and rate and make timely adjustments.

[0033] As Figures 4 - 5 shown, a plurality of guiding protrusions 101 are provided on the drug taking assembly 1, and a plurality of guiding grooves 301 are provided in the drug delivery end 304 of the aerosol jet assembly 3. The number and positions of the guiding grooves 301 and the guiding protrusions 101 correspond to each other, facilitating the fixation of the position of the drug taking assembly 1 in the aerosol jet assembly 3 and preventing the relative position between the two from shifting and causing liquid medicine leakage.

[0034] Figures 6 - 9 Another preferred embodiment of the medicinal inhalable aerosol jet device of the present invention is shown. This preferred embodiment adopts the same drug taking assembly 1, sealing ring 2, and part of the structure of the aerosol jet assembly 3. The difference is that in this preferred embodiment, the aerosol jet assembly 3 is in an I shape. The aerosol jet assembly 3 has two horizontal ports, namely the drug delivery end 304 and the mouthpiece end 305. The drug taking assembly 1 is assembled with the aerosol jet assembly 3 horizontally through the drug delivery end 304.
