Description

Technical Field

[0001] This utility model relates to the field of drug delivery device technology, specifically to an external drug delivery device. Background Technology

[0002] Currently, any medications applied to the body surface or certain mucous membranes that have insecticidal, antipruritic, anti-swelling, nodule-dispersing, pus-draining, tissue-regenerating, wound-closing, astringent, and hemostatic properties are called topical medications. To achieve the best results in terms of easy dispensing and even application, most topical medications are now available as fluid preparations such as ointments, creams, or gels.

[0003] However, in reality, it is difficult to control the dosage of topical medications dispensed by manual squeezing. If too much force is applied, it is easy to use too much medication, resulting in waste. At the same time, it can also lead to the phenomenon of applying large doses to avoid wasting the medication.

[0030] Working principle:

[0031] Example 1

[0032] Twist the transparent sealing cover 7 to separate the transparent sealing cover 7 and the top structure of the transparent sealing cover 7 from the transparent medicine box 2. Then, rotate the three composite partitions 4 to align the suitable medicine storage space with the transition cone tube 6. Then, reset the transparent sealing cover 7 and the transparent medicine box 2 to the threaded connection. Then, use the limiting plate to limit the three composite partitions 4 after rotation adjustment.

[0033] After the transparent dispensing box 2 and the transparent sealing cap 7 are reassembled, the external medication tubing 1 is squeezed to force the medication inside the tubing through the transition cone tube 6 to the storage space aligned with the transition cone tube 6, until the remaining space of the transition cone tube 6 and the storage space are filled. After completion, the valve inside the air guide valve tube 9 corresponding to the storage space with medication is opened and the composite sealing component 5 is turned off to make room for the flow channel and discharge pipe inside the air guide valve tube 9. Then, the folded airbag 81 and buffer spring 82 inside the passive air delivery component 8 are squeezed back and forth. The one-way valve tube 10 provides a one-way air pressure reset flow channel for the folded airbag 81, so that the air inside the folded airbag 81 is pneumatically squeezed through the air guide valve tube 9 to the storage space with medication. Then, by utilizing the combined effect of the weight of the medication inside the transition cone tube 6 and the medication inside the storage space and the pressure of the airflow, the medication can be quickly discharged through the discharge pipe for the next step of use.

[0034] Example 2

[0035] Twist the transparent sealing cover 7 to separate the transparent sealing cover 7 and the top structure of the transparent sealing cover 7 from the transparent medicine box 2. Then, rotate the three composite partitions 4 to align the suitable medicine storage space with the transition cone tube 6. Then, reset the transparent sealing cover 7 and the transparent medicine box 2 to the threaded connection. Then, use the limiting plate to limit the three composite partitions 4 after rotation adjustment.

[0036] After the transparent dispensing box 2 and the transparent sealing cap 7 are reassembled, squeeze the external medication tubing 1 to force the medication inside the tubing through the transition cone tube 6 to the storage space aligned with the transition cone tube 6 until the storage space is full. After that, twist the transparent sealing cap 7 to separate the transparent sealing cap 7 and its top structure from the transparent dispensing box 2. Then, directly take out the medication from the storage space and the medication from the transition cone tube 6 for use.
