Modelo de simulación pulmonar para educación


Oferta Tecnológica
Un hospital singapurense ha desarrollado un modelo de simulación pulmonar para mejorar la práctica de drenaje pleural. Este modelo permite la simulación de diferentes contracciones diafragmáticas y presiones pleurales y ayuda al personal médico a realizar simulaciones de permutaciones y condiciones pulmonares. El modelo imita la forma de los pulmones de mamíferos y se basa en un saco hinchable configurado con retroceso elástico modificando su espesor. El simulador también incluye un actuador acoplado a una membrana elástica para simular la relajación y contracción diafragmática. El hospital busca pymes y entidades de investigación médica con el fin de establecer acuerdos de licencia y cooperación en materia de investigación.


A novel lung simulation model for education.
A Singapore hospital has developed a lung simulation model which aims to improve the practice of pleural drainage, is capable of simulating different diaphragmatic contractions and pleural pressures, and aids in the training of medical staff where different permutations of lung conditions are simulated.

The organisation is interested in establishing license agreements or research cooperation agreements with SMEs of all sizes or healthcare research institutions.
Pleural effusion is a medical condition where abnormal fluid is collected within the pleural cavity. The excessive fluid must be drained since it can impair breathing by limiting the expansion of lungs.

Current practice of pleural drainage is inconsistent and varies widely in clinical practices. Available lung models are also limited in their ability to provide a realistic representation of a living human lung.

As such, medical device companies resort to testing their medical products on animal models while students rely on static models and mannequins to learn about the invasive pleural procedures. However, the anatomy of animal lung is different from human and results obtained may not translate well when applied on the human body.

To improve the training of medical personnel and reduce the inherent risks for patients undergoing the pleural drainage surgery, extensive expertise and training is required. This lung simulation model aims to aid in the training of medical staff where different permutations of lung conditions are simulated.

The model mimics the shape of living mammalian lungs, with an inflatable sac configured with elastic recoil by varying its thickness. It can therefore provide realistic trainings that have the capability of simulating different conditions, including negative and positive pleural pressures, diaphragmatic movements for variable respiratory rate, and pleural effusion conditions with variable effusion volume and type of fluids.

The lung simulation model can also consist of an actuator coupled to elastic membrane to simulate diaphragmatic relaxation and contraction, and can be programmed to vary its speed and magnitude to represent different lung tidal volume and respiratory rates.

Body cavities may accumulate fluids in diseased states. One example is the pleural cavity, a space between the parietal and visceral pleural within the human thorax. Accumulation of fluids resulting from diseases can cause ascites. Drainage of excessive fluid is currently done manually by inserting a catheter into the body cavity. It is dependent on the medical personnel´s experience and may result in severe danger if too much fluid is drained too quickly. The aim of a body fluid drainage device is to automate the system by allowing pre-selection of the drainage and volume drained.

The body fluid drainage device comprises a three-way tap to precisely control the rate and volume of fluid drained from body cavity via a catheter. To start the process of fluid drainage, the mini-motor will turn the knob of the three-way tap to a position that aligns the syringe with the catheter and syringe´s plunger will draw fluid out from the body cavity. After maximum capacity of syringe is reached, the drainage device will switch mode and align the knob on the tap with the chest drain box. Fluid from syringe is then ejected into the chest drain box. By repeating this process at the pre-selected rate, the desired volume of fluid is drained safely from the patient. The novelty of this device is the ability to drain fluids from body cavities at a controlled rate while measuring dynamic and static pressures.

The hospital is interested in establishing license agreements and research cooperation agreements with partner from the healthcare industry, such as an SME of any size to commercialise the technology, or with a research institute for further R-Y-D.
Advantages and Innovations:
The lung simulation model can be used as a teaching tool for medical personnel performing pleural drainage with different simulated conditions. It can also omit the use of animal models when medical device companies are testing their products.

With increasing aging population in many developed economies, the number of patients requiring pleural treatment due to lung infection will rise. Therefore, there is a need for a more consistent clinical practice and expertise in this area, for improve patient safety and clinical compliance standards.

With this lung simulation model, it enables medical practitioners to conduct more realistic trainings and acquire better skill set when treating patients with pleural effusion. Patients will also stand to benefit from the expertise and trainings received. There will be reduced inconsistency in treatment and improvement in patient safety and outcome.
