Sustainable device selection for flexible intubation scopes: Comparative environmental impact assessment of disposable and reusable flexible intubation scopes and concept design for sustainable flexible intubation scopes

Medical device selection is currently based on criteria including clinical performance, usability, safety and procurement costs. Growing awareness of the negative contribution of the healthcare sector to the total greenhouse gas (GHG) emissions demands environmental sustainability to be taken into account as well. Reusable and disposable...

Validation of Madymo Pedestrian Model for Reconstruction of Falling Incidents from Height

Falls are a significant cause of injury-associated deaths. In cases where the events leading up to a fall are unclear, a forensic investigation may be required to uncover the cause. During the forensic reconstruction process, tools for objective scenario evaluation are needed. Computer simulations appear to be a promising tool for reconstructing...

Therminus-K2: A Thermal Conductivity Measurement Device for Textile Layers at a Crime Scene

Each year, many people die due to non-natural causes of death, such as accidents, suicide, and murder and manslaughter. In these cases it is often necessary to investigate the cause, manner and time of death, which are investigated by forensic pathologists and the Police. To determine the time of death, the post mortem interval (PMI), the time...

Electromagnetic navigation in mandible reconstruction surgery: Introduction and assessment of a noninvasive method for patient registration

In patients with oral cavity cancer invading the mandible, a segmental bone resection is performed and the original contour of the mandible is reconstructed with a free fibula flap. Virtual surgical planning is performed prior to surgery to determine the locations and orientations of the osteotomy planes on the mandible and fibula. Currently,...

DropAdjust: infusion flow regulator: Design and development of a precise and accurate manually controlled over-line flow regulator for gravity-driven infusion

Worldwide 70-90% of hospitalised patients receive intravenous infusion at some stage during their stay. In many situations, a high degree of infusion accuracy is essential as deviation from the intended dose can quickly become dangerous and moreover costly. Electronic infusion pumps provide the most accurate way of infusion, but they require...

Conceptual design of an anthropomorphic shake doll: Development of requirements for an anthropomorphic shake doll and design of an artificial joint for investigating the infant’s body kinematics during shaking.

Infant shaking can cause serious damage (inflicted head injury by shaking trauma), it’s occurrence indicates the necessity for infant protection. To ensure reliable jurisprudence, it is important to know the exact consequences of shaking on an infant’s body. These consequences can be researched by the use of an anthropomorphic shake doll. With...

Optimization process of the forensic investigation regarding home invasion robberies

The forensic investigation is one of the first steps in the criminal investigation process concerning home invasion robberies. The forensic investigation consists of objectively capturing the crime scene as it is when starting the investigation. Regarding home invasion robberies, the most important traces are fingerprints and DNA which are used...

Inflicted Head Injury by Shaking Trauma in Infants: Part I: The potential effect of spatiotemporal variation of the rotation center on injury mechanisms. Part II:The importance of spatiotemporal variation of the rotation center when modeling external head-dynamics

Part I:<br/>Inflicted head injury by shaking trauma (IHI-ST) is often simulated to better understand the injury mechanisms and to analyze whether violent shaking can cause head injury in infants. Computational models are usually subjected to linear and rotational inputs to simulate shaking scenarios. In existing studies, the head’s rotation...

Microbial tightness of O-ring seals. Case study: duodenoscopes: Evaluation of the sealing efficiency against bacteria of the distal O-ring seal of the Olympus TJF-Q180V duodenoscope

Sealing constructions are frequently used in reusable instruments to prevent the loss of fluids or gasses in a construction by obstructing flow through the glands in the interface of two or more separate parts, and may be applied to seal patients' body fluids. Patient material contains various types of microorganisms, and with the increase of...

The influence of contact force on forensic trace collection efficiency when sampling textiles with adhesive tape

DNA can function as a significant part of evidence in forensic investigation, because it can link a potential perpetrator to a crime. Even by skin contact, micro-traces of DNA-containing material can be transferred. This type of DNA is called ‘trace DNA’. When DNA is collected from an evidentiary item for forensic purposes, the goal is to...

Development of a variable rigidity guide wire

In some types of endovascular surgery on the aorta, a catheter needs to be placed in a renal artery to enable renal artery stenting. Therefore, a catheter and a medical guide wire are maneuvered through the vascular system and placed inside the renal artery. In one in eight patients, the renal artery is angulated ≤50°, which could cause the...

Design of an Environmentally Interactive Continuum Manipulator

Continuum manipulators are high degree of freedom structures that can use their increased degrees of freedom to navigate through an environment with obstacles. This type of manipulator is underactuated, which make them promising for adapting to their environments. However, current research is mainly focused on accurate positioning and obstacle...

Image processing of optical coherence tomography for image guided dental drilling

In the past two decades, dental implants have been an essential component of the public health. However, lack of a reliable and safe dental surgery imaging modality remains a major problem. Optical coherence tomography (OCT) is an interferometic optical imaging modality that is somewhat similar to B-mode ultrasound but utilizes infrared light...

Development of PlastoLock overtube with temperature controlled rigidity for colonoscopy

To diagnose and treat colon cancer a colonoscopy is usually performed. Current colonoscopy is performed by advancing a colonoscope (scope) through the tortuous colon. However, the flexible scope often buckles when advanced. This can cause discomfort and pain for the patient and can make the examination of the colon difficult for the endoscopist....
