Description

TECHNICAL FIELD

[0001] The utility model relates to semi -solid preparation dosing technical field more specifically, it relates to a kind of multiple dose semi -solid preparation dosing device. BACKGROUND

[0002] The inner package of semi-solid preparation drug is generally soft bottle, and the semi-solid preparation is discharged by manual extrusion of bottle body, so that quantitative dosing cannot be realized;

[0003] Generally, semi-solid preparations do not require precise control of the dosage, but some specific drugs (estrogen, interferon) require quantitative dosing and precise control of the amount used. For example, estradiol gel cannot be dosed quantitatively, and a specific measuring device (ruler) is used in conjunction with the medicine bottle. The medicine must be squeezed into the measuring device before quantitative dosing can be achieved, which is very inconvenient.

[0004] Quantitative dosing semi-solid preparation bottles refer to semi-solid preparation products designed for precise control of the dosage of the drug. These semi-solid preparations are typically used for topical administration to the skin, eyes, nasal cavity, oral cavity, vagina, anus, urethra, and external ear canal, or other body surfaces or cavities. These preparations are suitable for different medical purposes due to their unique physical state and penetration properties. Ensuring that patients receive the exact amount of medication each time is particularly important for ensuring treatment effectiveness and avoiding side effects.

[0005] After searching, there are several ways to achieve quantitative dosing of semi-solid preparations:

[0006] Ointment bottles with measuring pumps: Some ointment packages are equipped with precise measuring pumps, and each press of the pump head releases a pre-set dose of ointment, such as certain corticosteroid ointments.

[0007] Single-dose packaging of semi-solid preparations: Semi-solid preparations are pre-packaged in small bags or tubes, and each package is a single dose, ensuring the accuracy of medication use and facilitating portability and hygiene.

[0008] Applicator / dispenser accessories: Some ointments come with special applicators or dispensers that have scales or fixed-dose release mechanisms to help users control the amount of medication.

[0009] Patch-type ointments: Although not entirely traditional ointments, some medications are delivered through patches, which inherently limit the amount of medication released, achieving the goal of quantitative dosing.

[0010] Digital health aids: With the development of technology, some smart devices or applications begin to combine with drug packaging, providing personalized medication guidance and dose tracking through scanning or connecting electronic devices, although this is not the design of the semi-solid preparation itself, but it can help achieve more accurate administration.

[0011] In addition to the advantages and disadvantages of the above administration methods, we refer to the products of pre-filled syringes (usually single-dose packaging of liquid preparations), insulin injection pens (dose dispensing devices for multi-dose injections) and screw micrometer principles to design a multi-dose semi-solid preparation inner packaging that can dose dispensing. Due to the physical properties of semi-solid drug preparations:

[0012] In order to smoothly push the medicine out of the piston, a rubber is arranged on the contact surface between the piston and the inner wall of the bottle body, resulting in a large friction between the piston and the bottle body. It is not easy to push the push rod with less force, and when the force is too large, the piston moves a long distance forward, resulting in too much medication and making it difficult to achieve dose dispensing.

[0013] Some push rods and bottle bodies are connected by threads. When medication is needed, the push rod is rotated, which drives the piston to move inward until the scale line on the side of the piston corresponds to the scale line on the side of the bottle body. When the device is not in use, it is easy to cause the push rod to rotate in the opposite direction and drive the piston to deviate from the previous scale line. When it needs to be used again, it is not easy to control the amount of medication according to the difference in scale lines, which will cause deviation. Practical new type
