The hospital intends to transfer the said achievements through negotiated pricing.“A Rapid Infusion Device”The relevant patents were assigned to Langhao Medical Technology (Hunan) Co., Ltd., with a transfer fee of RMB218,800 yuan. The inventor of this patented technology isWang Jie and her team。

The assignee of this patent isLanghao Medical Technology (Hunan) Co., Ltd., is a comprehensive medical technology enterprise focused on the research and development, production, sales, and related technical services of medical devices, and is an affiliate of Langhao Medical. With the core positioning of “deepening engagement in the healthcare sector, developing high-quality medical products, and providing comprehensive technical support services,” it is dedicated to the R&D and manufacturing of Class I, Class II, and Class III medical devices, covering a wide range of products including medical hygiene materials and dressings, visualized anesthesia instruments, rehabilitation equipment, and gynecological gels.

The invention patent proposed for transfer in this instance isA Rapid Infusion Device for Medical Emergency Scenarios, designed to meet the need for rapid fluid resuscitation in patients with massive hemorrhage, replacing the traditional method of manual squeezing of IV bags by healthcare professionals, thereby improving rescue efficiency. Its core design centers on the automatic and continuous compression of IV bags, combining ease of operation with controllable pressure.

Emergency InfusionIt is a core component in the resuscitation of critically ill patients with conditions such as massive hemorrhage and shock; rapid and stable fluid resuscitation directly impacts the stabilization of vital signs and the success rate of treatment.

However, in current clinical emergency settings, the inherent flaws of traditional infusion methods have led to a concentrated outbreak of pain points: existing rapid fluid resuscitation primarily relies on healthcare professionals manually and continuously squeezing infusion bags, lacking support from dedicated automated equipment, which severely limits emergency infusion work by human resources.

Such scenarios pose multiple challenges for both healthcare providers and patients: For patients, the force of manual compression is difficult to maintain consistently, leading to fluctuating infusion rates that compromise rehydration efficacy and may even cause physical discomfort due to pressure variations; furthermore, any interruption in compression during emergency care can halt fluid resuscitation, thereby delaying optimal treatment.

For healthcare professionals, prolonged manual compression is not only physically demanding but also consumes time that could otherwise be dedicated to critical tasks such as vital signs monitoring and medication preparation, resulting in a waste of emergency resources. Particularly in scenarios involving the simultaneous resuscitation of multiple patients or staffing shortages, manual compression fails to balance efficiency and quality, severely hindering the rapid response capability of emergency care.

Currently, mainstream rapid infusion solutions still rely onManual CompressionSome hospitals have attempted temporary measures such as applying simple weights for pressure, but these methods suffer from uncontrollable pressure and a tendency to compress infusion bags, leading to impaired fluid flow. Furthermore, they cannot dynamically adjust pressure based on the remaining fluid volume. A few specialized infusion assistance devices are plagued by complex structures, cumbersome operation, and insufficient flexibility in adjustment. They struggle to accommodate infusion bags of different specifications and fail to provide timely feedback on pressure changes, necessitating frequent monitoring and adjustment by medical staff, which results in poor ease of use.

Furthermore, existing solutions generally lack pressure monitoring and alert functions. When the fluid level in the infusion bag drops, resulting in insufficient squeezing force, the failure to detect this issue in a timely manner can compromise infusion efficiency. These pain points have created an urgent market demand for a rapid infusion device that is easy to operate, maintains stable pressure, allows dynamic adjustment, and features intelligent alerts. Such a device would fill the gap left by traditional solutions in terms of “labor-saving, high-efficiency, and precision,” thereby addressing the core challenges of emergency infusion.

This rapid infusion device, with its precise structural design and functional compatibility, specifically addresses the core pain points of traditional emergency infusion, demonstrating“Labor-saving and efficient, stable and controllable pressure, simple and easy to use”Three Core Advantages: Providing More Reliable Rapid Fluid Resuscitation Solutions for Emergency Scenarios.

Automatic Continuous Compression: Reduces Manual Labor and Enhances Efficiency.The device achieves continuous compression of infusion bags through an elastic assembly consisting of a pressure plate and multiple sets of primary springs, eliminating the need for prolonged manual pressing by medical staff. This completely frees up emergency manpower, allowing healthcare professionals to focus on critical tasks such as monitoring patient vital signs and preparing medications, thereby significantly enhancing emergency response speed.

Meanwhile, the elastic component provides uniform and sustained compressive force, eliminating fluctuations in infusion rate caused by inconsistent manual pressure. This ensures rapid and stable fluid delivery, thereby securing the critical "golden hour" for life-saving intervention in critically ill patients suffering from massive hemorrhage, shock, and other emergencies.

Multi-level Adjustment + Smart Reminders for Precise and Controllable Pressure.The device is equipped with an adjustable buckle assembly featuring at least three-tiered detents. By engaging the latch with detents at different positions, the angle between the first and second cover plates can be flexibly adjusted. As the fluid volume in the infusion bag decreases, healthcare personnel need only squeeze the cover plates upon prompt, allowing the latch to automatically switch to the next lower detent. This maintains stable compressive force exerted by the pressure plate on the infusion bag, preventing insufficient compression due to reduced fluid volume from compromising infusion efficiency.

Furthermore, the pressure sensor on the compression plate monitors pressure data in real time. When the pressure falls below a preset threshold, the alert unit automatically issues a notification, eliminating the need for frequent checks by medical staff. This enables intelligent feedback on pressure status, ensuring that the infusion process is precise and controllable.

Simple structure with strong adaptability, easy to operate and maintain.The core structure of the device consists of key components such as a cover plate, pressure plate, and buckle assembly. Its streamlined design, free from complex redundancies, not only reduces the probability of failure and maintenance costs but also ensures a compact footprint. Equipped with an annular fixation component, the device can be conveniently mounted onto IV poles, making it suitable for various scenarios including hospital wards and emergency ambulances.

The hook design within the IV bag compartment effectively prevents the bag from dislodging during compression. The first and second notches accommodate the infusion port protrusion and air venting requirements, respectively. The operation is simple and intuitive: merely open the cover, place the IV bag, and compress to secure it to initiate infusion. For replacement, simply move the unlocking tab to release the bag. No complex training is required, allowing medical staff to quickly master its use. Additionally, it is compatible with IV bags of various specifications, offering strong versatility.

The current market for emergency infusion pressure devices has formed a dual structure of “traditional manual assistance + intelligent automated pressurization,” with domestic and international enterprises focusing on“Liberate manpower, stabilize pressure, and enhance safety”Strategic layouts are being developed around core demands, with products demonstrating differentiated development in drive mechanisms, pressure control precision, and scenario adaptability; automation and precision represent the mainstream R&D directions.
