Hip fracture repair is a common surgical procedure that residents learn early in their careers. Efficient fluoroscopy use and the precision of fixation can have an important influence on patient outcomes. This study used a wire navigation simulator to assess patterns in behavior between less experienced and experienced surgeons. The hypothesis was that experienced surgeons would have more controlled hand motions, higher accuracy in obtaining an entry point, and use less fluoroscopy than less experienced surgeons.\u0000 A new simulation module for the cephalomedullary nail wire navigation task was developed, including a solid Sawbones model and visually and haptically realistic soft tissue. Second- and fifth-year residents found an appropriate entry point and drive their k-wire into the femoral shaft. Each participant repeated this task twice.\u0000 Experienced surgeons had a starting point on average 1.77 mm more accurate than less experienced surgeons (p = 0.045), and experienced surgeons were more consistent in their starting point. Neither group used significantly more images or time (p = 0.097 and p = 0.061, respectively). Surgeons who consistently used larger corrections typically required more images to find their entry point. Each corrective movement with a swept area larger than 1329.7 mm2 was estimated to add between 1.53-2.25 images to the total needed.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130997826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the battery of a VI becomes depleted, stimulation interruptions can cause vertigo. To avoid this, VIs can use alert signals such as vibration and beeping to remind the user to replace the battery. However, in distracting and noisy environments typical of activities of daily life, some patients may fail to hear or feel those alerts, so a physiological signal can be used as an alternate channel for signaling battery depletion. Pauses in the stimulation waveform can be delivered for this purpose, with the length of the pause long enough to be detected reliably by the patient but not so long as to induce dizziness or a vertigo attack. As a guide for the design of a physiologic battery depletion alert system, this study reports the ability of nine longterm, continuous VI users to detect stimulation pauses of various durations. We also show the effect of distraction on patients’ detection thresholds and response latencies for detected events.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114476462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By having the abilities to assess marginal lungs, extend preservation times, and expand geographical distances for donations, EVLP has effectively both expanded the human lung transplantation donor pool and shortened times on the transplant waitlist. While clinical usage has expanded, preclinical research on EVLP has not. EVLP can be utilized as a preclinical research model, i.e., to investigate pharmacological responses (e.g., post-conditioning agents), organ preservation, device testing and/or methodology development. To facilitate the use of EVLP as a research tool, we have developed a low-cost testing system with ever increasing capabilities e.g., the use of a novel continuous weight sensor to evaluate lung edema. Real time tracking of edema allows us to hone in on potential causes of lung damage, and investigate techniques to rehabilitate and mitigate damage on a short time scale (<8 hours). This system enhances our abilities to accurately test medical devices, lung physiology, and potential treatment impacts on lungs.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129399932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiencing cognitive decline, resulting in relying on others for daily living activities and impairment in basic mental tasks are the main symptoms. There are yet no proven treatments to slow or prevent neurodegenerative dementia progression; thus, dementia patients eventually need full-time care. To help patients to stay in their own homes longer and ease the caregiver burden, Smart Assistive Technology (SAT) products may be beneficial. One of the basic activities that Alzheimer’s patients in particular need help with, are basic hygiene needs such as brushing their teeth. A smart toothbrush has been designed and implemented as a pilot study towards development of a SAT for basic hygiene functions of dementia patients, while it can also have educational application for children. The design includes hardware and software. The hardware includes 9-Axis motion sensor, individually addressable light-emitting diodes (LEDs), Bluetooth Light Energy (BLE) communication module, laser distance sensor and other electrical components. The software includes real-time monitoring of several dependent and independent tasks using an algorithm to assist the users and transmit that data to a smartphone application. The real-time monitoring system of the designed prototype assists the users by visual and auditory means. It is anticipated the designed prototype will assist people with dementia, and hopefully prolong the time they can be cared for at home; it may also be used for oral hygiene education and instruction in general.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125148931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detection and molecular characterization of CTCs are pivotal for early-stage cancer diagnosis and prognosis. Recently, microfluidic technology has achieved significant progress in the separation of cells from complex and heterogeneous mixtures for many biomedical applications. Conventional microfluidic platforms exploit the difference in size between the particles to achieve separation, which makes them ineffective for sorting overlapping-sized CTCs. To address this issue, we propose a method using a spiral channel for label-free, and high throughput separation of CTCs coupling Dielectrophoresis (DEP) with inertial microfluidics. A numerical model has been developed to investigate the separation effectiveness of the device over a range of electrical voltage and flow rates. The presented channel is shown to effectively isolate similar-sized CTCs from the white blood cells (WBCs) in a single-stage separation process. Subsequently, optimum working parameters to enhance separation efficiency have been proposed. The hybrid microfluidic device can provide valuable insight into the development of a robust, inexpensive, and efficient platform for cell separation with reduced analysis time for future cancer research and treatment.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131019098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
