Design and Functionality of 30ml Enema Bottles

30ml enema bottles are essential medical devices used for rectal administration of fluids, medications, or cleansing solutions. These small-volume containers are designed for precision, hygiene, and ease of use in both clinical and home care settings. Over time, three primary design types have emerged—each tailored to specific applications, solution viscosities, and user requirements: Through Type, Plug Type, and Nozzle Type. Understanding these designs helps healthcare providers and manufacturers select the most appropriate option for patient safety and treatment efficacy.

Types of 30ml Enema Bottle Designs

Through Type

This design features a bottle with a narrow opening at one end and a nozzle of matching diameter at the opposite end, creating a continuous passageway from reservoir to delivery point. The seamless internal pathway minimizes resistance during fluid expulsion, making it ideal for thicker solutions or suspensions containing particulates.

Because there are no internal valves or complex chambers, the through type reduces the risk of clogging and allows for more complete evacuation of viscous formulations such as mineral oil, herbal mixtures, or medicated suspensions. This makes it a preferred choice in clinical environments where reliable delivery of non-liquid preparations is required.

Plug Type

The plug-type enema bottle includes a nozzle attached directly to the neck of the container, which is sealed with a screw-on cap or plug. This design supports pre-mixing or agitation of the solution within the bottle before administration—making it suitable for preparations that require dissolving powders or blending components immediately prior to use.

However, due to potential leakage risks and structural limitations, this type is not recommended for thick, gel-like, or particulate-heavy solutions. It works best with low-viscosity liquids such as saline, water-based laxatives, or diluted medications. The secure seal also enhances portability and sterility, especially in single-use or travel-ready kits.

Nozzle Type

In the nozzle-type design, the delivery tip is fitted onto the bottle mouth via an open-ended connection system. This allows for modular assembly and, in some variants, the use of interchangeable nozzles suited for different patient needs—such as pediatric, adult, or post-surgical applications.

Some models include a dedicated instillation chamber or flow control mechanism to regulate the rate of fluid delivery, improving patient comfort and reducing the risk of overpressure. While certain versions support replaceable nozzles, many are designed for single-use only to maintain sterility and prevent cross-contamination. This design emphasizes hygiene and controlled administration, particularly in hospital settings.

Material & Hygiene Considerations

Most 30ml enema bottles are made from medical-grade polyethylene or polypropylene, ensuring chemical resistance, flexibility, and compatibility with a wide range of pharmaceutical agents. These materials are non-toxic, latex-free, and often pre-sterilized using gamma irradiation or ethylene oxide processes.

Transparency allows for easy volume measurement, while graduated markings on the side enhance dosing accuracy. To maintain sterility, all designs typically come sealed in individual blister packs or pouches until use. Proper disposal after single use is critical to infection control and regulatory compliance.

Design Type	Best For	Solution Compatibility	Key Advantages
Through Type	Thick suspensions, oils, herbal mixtures	High viscosity, particulate-containing	Clog-resistant, full evacuation, simple design
Plug Type	Solutions mixed before use, portable kits	Low to medium viscosity, clear liquids	Secure seal, mix-and-use capability, leak-resistant
Nozzle Type	Controlled instillation, clinical use	Standard liquid formulations	Hygienic, optional replaceable tips, precise flow
