Problems solved by technology

The end of the tube is a cavity, which can be placed with fibrous materials or porous materials. As mentioned above, the combination of single drugs often brings a lot of inconvenience to patients. However, for compound drugs, due to the combination of two or more drugs and auxiliary materials Due to the differences in size, shape, fluidity, electrical properties, dispersibility and hygroscopicity between various particles, the stability and uniformity of the drug will be affected by uncertainty during the packaging and storage process.
There may be a risk of physical and chemical reactions between them, resulting in reduced efficacy or even toxic side effects

Embodiment 21

[0068] A drug delivery device suitable for a combination of multiple drugs, such as image 3 As shown, it includes a variety of drug carriers as described above, an opening position is set on the bottom part 2 for opening the cavity bag 1, and the opening position is connected with the driving mechanism 5 for opening the cavity bag , also includes a drug delivery port 4 that communicates with the opened cavity bag. In this embodiment, the bottom part is a base, and the cavities are periodically arranged on the base, and the cover is a cover, laid on the base to protect the inside of the cavities. The medicine does not leak out, and the driving mechanism includes a cover sheet driving member capable of pulling the cover sheet apart. Taking the inhaled medicine as an example, in the drug delivery device of the present invention, about 10-15% of the inhaled medicine particles inhaled by the user can directly reach the lungs of the human body, and the device is quick to use, quic...

Embodiment 22

[0077] A device for producing a variety of drug carriers as described above, such as Figure 4As shown, it includes a cabinet 6, the interior of the cabinet is a working space 7, and a plurality of working mechanisms 8 are arranged in the working space 7. Arranged in the working space, the working mechanism 8 includes a conveyor belt 8-1 for placing the bottom piece, a filling device 8-2 for filling the cavity with medicine, and a sealing mechanism. 6 is connected to a ventilation mechanism 9 connected with the inside of the case, and an air outlet mechanism 10 is provided on one side of the case 6 . The device for producing multiple types of drug carriers in the present invention can effectively avoid mixing two kinds of drugs during the drug filling process. Specifically, take filling three medicines as an example. The three medicines are medicine A, medicine B, and medicine C respectively. The capsule is closed. At this time, the ventilation mechanism 9 makes the working ...

Embodiment 23

[0081] In the present invention, a cleaning unit 11 is arranged between every two adjacent working mechanisms. Such as Image 6 As shown, the number of the working mechanism 8 in this embodiment is equal to the type of medicine contained in the cavity bag and is two, which are respectively the first working unit 81 and the second working unit 82, and the first working unit 81 and the second working unit 82 respectively. A cleaning unit 11 is installed between the second working unit 82, and the ventilation mechanism 9 includes a first ventilation unit 91, a fresh air unit 93 and a second ventilation unit 92, and the first working unit 81, the cleaning unit 11 and the second working unit The unit 82 is connected to the first ventilation unit 91 , the fresh air unit 93 and the second ventilation unit 92 respectively. This embodiment is specifically aimed at the production of a drug carrier carrying two drugs, which first fills the first drug through the first working unit, then...

Abstract

The invention relates to a medical product, and provides a drug carrier for combined medication. The drug carrier includes a separable base member and a cover member, the separable base member is provided with a plurality of spaced apart cavity bags thereon, the cover member hermetically covers the base member, each cavity bag stores a single-dose pharmaceutical preparation, and two or more single-dose preparations containing different active ingredients are periodically stored in the cavity bags. According to the invention, aiming at different patient groups, in particular to patients who need to be treated with the relieving drugs according to requirements while using the controlling drugs, two or more products are combined into a whole into a delivery device, so that the medication compliance of the patients is improved, and the potential chemical reaction of different drugs in the storage process is avoided.

Description

technical field [0001] The invention relates to the field of medical products, in particular to a drug carrier and system for combined drug use. Background technique [0002] With rapid economic development, industrialization, and changes in people's lifestyles, the global prevalence of asthma and chronic obstructive pulmonary disease (COPD) is showing a rapid upward trend, becoming one of the important chronic airway diseases that seriously endanger people's health. one. Asthma is a chronic airway inflammatory disease involving a variety of cells including eosinophils, mast cells, T lymphocytes, neutrophils, smooth muscle cells, airway epithelial cells, and cell components. COPD is a preventable and treatable disease characterized by persistent airflow limitation, which is mostly progressive and associated with an increased chronic inflammatory response of airways and lung tissues to noxious gases or particles such as tobacco smoke related. COPD primarily affects the lun...
