Official Release of Achievements

Against the growing global challenge of healthcare‑associated infections, Manners Technology has launched the SafeDispose 360° - a full‑process safe disposal solution for AVF needles. Safety‑disposal concepts are embedded from the earliest stage of needle design, supported by smart hardware, standardised workflows and a digital management platform. At the first 100 large‑scale dialysis centres adopting this system, the needlestick injury rate has dropped by 92 %, the medical waste mis‑sorting rate has fallen below 0.5 %, and 100 % of infectious AVF needle waste has undergone harmless disposal. This builds a robust biosafety barrier for healthcare workers, patients and the public.

R&D Background and Clinical Pain Points

Used AVF needles rank among the highest‑risk infectious sharp waste. Their disposal chain is long and multi‑stage, with hidden safety hazards at every node:

Risks during bedside separation and discarding: After dialysis, nurses manually separate needles from tubing, putting them at high risk of needlestick injuries and exposure to blood‑borne pathogens such as hepatitis B, hepatitis C and HIV.

Loopholes in sorting and temporary storage: Needles may be incorrectly mixed into general medical waste or recyclables, causing cross‑contamination. Overfilled, unsealed or substandard sharps containers may lead to needle protrusion.

Risks during transportation and handover: Waste may leak during intra‑hospital transfer. Unclear records during handover with third‑party disposal contractors can result in illegal dumping or waste leakage.

Incomplete end‑of‑life disposal: Insufficient incineration temperature or duration may fail to fully eliminate pathogens. Poor anti‑seepage measures at landfills can contaminate soil and groundwater.

Core Technological Innovations

The manufacturer has built an integrated hardware‑software system covering the full chain: generation → sorting → collection → temporary storage → transportation → disposal.

Built‑in safety design at the source: An integrated needlestick‑prevention structure is adopted in needle development. Laser welding, rather than adhesive bonding, connects hubs and cannulas to prevent separation during disposal. Meanwhile, a one‑hand needle‑cap recapping device is developed, enabling nurses to instantly shield needle tips with one hand after removal, completely avoiding the high‑risk two‑hand recapping action.

Smart IoT‑enabled sharps collection terminals: Equipped with weight sensors, volume visual recognition and RFID tags, these containers automatically weigh and count needles upon insertion. An alarm triggers and alerts logistics staff when volume reaches three‑quarters capacity. Constructed from puncture‑ and tear‑resistant composite materials, sealed containers cannot be illegally opened. Real‑time data is uploaded to the management platform via wireless networks.

Digital traceability management platform: A full‑life‑cycle medical waste traceability system is established. Each smart sharps container has a unique electronic ID. Every stage - from generation at dialysis units, intra‑hospital temporary storage, transportation to incineration at disposal centres - is recorded via QR‑code scanning or RFID sensing, generating tamper‑proof electronic documents to realise traceable sources, trackable destinations and accountable responsibilities.

End‑of‑life disposal verification technology: In partnership with disposal facilities, online temperature monitors and video surveillance are installed at key incinerator points. Real‑time data is transmitted to the management platform to strictly enforce national standards requiring infectious waste incineration at ≥ 850 °C for ≥ 2 seconds. Regular testing of incineration residues for dioxins and heavy‑metal residues ensures thorough harmless treatment.

Mechanism of Action

The system systematically reduces risks through multi‑layered interventions of engineering controls, administrative controls and behavioural controls:

Engineering controls eliminate hazards: Integrated anti‑stick designs and one‑hand recapping devices physically eliminate needlestick injuries, the most effective risk‑control strategy.

Administrative controls standardise workflows: The digital traceability platform transforms manually‑dependent processes into system‑enforced standardised operations. System alerts are triggered by anomalies at any stage (e.g., overdue sharps‑container collection, deviated transportation routes), prompting immediate action by relevant personnel.

Behavioural controls raise awareness: Real‑time feedback from smart terminals (e.g., displaying collected needle quantities, capacity‑threshold alarms) reinforces safe practices among healthcare workers. Individual and department‑level safety reports generated by the platform convert vague infection control into quantifiable, comparable performance indicators, boosting overall participation.

Efficacy Validation

A six‑month controlled study of the SafeDispose 360° system was conducted across 20 affiliated units of a provincial blood purification quality‑control centre.

Needlestick injury rate: After system adoption, reported AVF‑needle‑related needlestick injuries fell from an average of 5.2 cases per month to 0.4 cases, a 92.3 % reduction. The few remaining incidents were linked to improper device use (e.g., forced opening of sealed sharps containers).

Waste‑sorting accuracy: Combining platform data with on‑site audits, 99.8 % of infectious sharp waste was correctly placed into smart sharps containers, with near‑zero mis‑sorting.

Disposal compliance rate: Online monitoring confirmed 100 % compliance with incineration temperature and duration standards across all participating facilities. Historical data is available for audit at any time, resolving long‑standing regulatory challenges reliant on paper records and occasional spot checks.

Cost‑benefit analysis: Despite initial investment in smart hardware, overall costs associated with post‑exposure prophylaxis, testing, sick leave and psychological intervention following needlestick injuries dropped significantly, with investment payback expected within 18 months.

R&D Strategy and Philosophy

Manners Technology's safe‑disposal strategy embodies the profound philosophy of building safety into the full product life cycle. It recognises that product safety should extend beyond patients to every healthcare and logistics worker handling the device. Its R&D follows the S.A.F.E. principle: Source Reduction, Administrative Control, Facility & Engineering Control, Education & Training. Deep collaboration with hospital infection‑control departments, nursing departments and logistics teams ensures the solution functions not as an isolated technical silo, but as an enabling tool seamlessly integrated into existing workflows.

Future Outlook

Future safe‑disposal systems will become more intelligent, automated and human‑centred. Manufacturers are developing an AI vision‑based needlestick‑prevention system: cameras installed in dialysis areas use AI algorithms to monitor nursing operations in real time, triggering voice alerts upon detection of high‑risk actions such as two‑hand recapping or exposed‑needle placement. Meanwhile, a bedside automated sharps‑processing robot is being explored: a compact unit integrated with dialysis machines automatically cuts and disinfects used needle‑tubing assemblies after insertion by nurses, discharging treated waste into sealed containers for zero‑contact disposal. At the management level, big‑data predictive models will be integrated to forecast medical‑waste generation by department based on dialysis patient volumes and seasonal disease patterns, optimising collection routes and frequencies for lean management. The ultimate goal is to build a smart dialysis environment free of needlestick injuries and cross‑infection, with full‑process traceability.
