With the development of artificial intelligence (AI)-augmented auscultation tools, physicians could improve their auscultation skills and provide accurate diagnoses, even approaching the expertise of seasoned clinicians. Although a few AI auscultation platforms have been created, none have been adopted widely in clinical settings. Our goal is to develop a comprehensive digital auscultation platform, termed StethAid, to supplement the value of auscultation.\u0000 StethAid is a comprehensive auscultation platform that comprises of an electronic stethoscope, mobile applications, and website portals. The StethAid stethoscope enables streaming and recording of heart and lungs sounds. It features 100 levels of sound amplification, digital filtering, active noise cancellation, and wireless connectivity. The StethAid stethoscope is similar to FDA-approved stethoscopes in its frequency response. Our mobile apps deliver various auscultation tools, as well as an AI suite and remote auscultation capabilities. The AI suite includes deep learning-based automated wheeze detection from auscultated lungs sounds. StethAid has been rigorously validated technically and clinically. StethAid could assist physicians in making more informed decisions, potentially leading to improved patient outcomes.","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":"124804369","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 ability to continuously measure blood flow in major cerebral arteries would enable the early detection of medical problems such as stroke. However, current ultrasound technology consists of rigid, hand-held probes that are arduous to use, sensitive to movement, and are primarily designed for intermittent, instead of continuous use. Here, we describe the design of a wearable ultrasound patch for continuously measuring blood flow velocity through the middle cerebral artery (MCA) that can be assessed from the temple region of the head. The wearable ultrasound patch is composed of an array of piezoelectric elements that are wired together using flexible electrical conductors and encapsulated in an elastic substrate. To improve ultrasound energy transfer, a soft and conformal composite matching layer is introduced. The matching layer consists of gallium-based liquid metal (LM) microdroplets dispersed in a silicone elastomer. The acoustic impedance of the matching layer can be tuned by varying the volume loading of LM. The wearable ultrasound patch will provide new opportunities to continuously measure blood flow velocity and ultimately enable early detection of medical problems such as stroke.","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":"133029891","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}

Based on the clinical need and practical use discoveries of that first trial, this paper outlines the development of a second-generation device that activates specific nerves through vibrotactile stimulation applied to the skin. Several major steps in this process were the iterative design process, physical prototyping, conceptual modeling, and benchtop testing. Furthermore, this next generation device was tested with epilepsy patients undergoing invasive monitoring (stereotactic electroencephalography, sEEG) to collect electrophysiological measurements via implanted electrodes in the brain. Early findings showed differential modulation of delta power in response to 2 Hz median nerve stimulation, but not during 12 Hz median nerve stimulation or 2 Hz ulnar nerve stimulation, hence indicating differential encoding of vibration features depending on frequency and spatial parameters. These patient trials also served to collect feedback for the continued development of the device to improve aspects such as ease of use, patient comfort, and ideal application of the vibration stimulus. Testing and development are ongoing with the enhancement of vibration isolating structures, more comfortable contact points, more durable additively manufactured structures, and embedded force sensors in the device.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"34 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":"131354615","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}

Advances in clinical monitoring can potentially drive improvements in survival and long-term outcomes in this vulnerable population. In this study, a multi-function catheter with ECG, pressure, and temperature sensors is developed and the performance and ideal lead location are tested in a rat model. The ECG signals, transdiaphragmatic pressure, and core body temperature of the rat were recorded from a modified multi-electrode gastric feeding tube with one pressure sensor at the tip and another pressure sensor and temperature sensor at 6 cm from the trip.\u0000 The ECG signals were obtained from esophageal electrodes in multiple locations and eventually, optimal electrode locations were identified at 4 and 6 cm from the tip of the feeding tube. Reliable pressure signals at a pressure range of 0-0.2psi (0-14 cm H2O) were obtained from pressure sensors placed above and below the diaphragm. A core temperature of ~41°C was recorded from the temperature sensor which was elevated relative to the rectal temperature measurements due to the experimental setup used.\u0000 Our multifunction catheter proved to provide a reliable, strong, high resolution and low noise ECG signal from the esophageal electrodes in an animal model equivalent in size to the preterm infant. In addition, continuous pressure and temperature recordings can simultaneously be extracted, with all 3 sensors contained within a less than 3 mm diameter tube as is routinely used in this population. Integration of these multiple components into a feeding tube, which is already universally used in this population purely for nutrition, will provide significant advances in vital sign monitoring while reducing risk to vulnerable preterm infants.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"296 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":"121721094","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}

Previous work demonstrated that the reversing of flow through the proximal catheter can restore flow through a blocked catheter. Periodic backwash through the proximal catheter can prevent obstructions and maintain adequate drainage. This project aims to design a pump that can periodically reverse the flow of CSF to backwash the proximal catheter. To reduce the complexity of the implanted components, a simple diaphragm pump can be externally actuated. Actuation of the pump can be achieved using an electromagnet located outside of the body; a metal cap placed on the diaphragm can be magnetically manipulated to pump CSF and backwash the proximal catheter. Testing demonstrates the feasibility of this pump design with an achieved flow rate of 3.4 to 4 mL/min. This bicorporal pump used as part of a backwashing system may favorably change the shunt failure rate and provide a more robust treatment for hydrocephalus.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121458413","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}
