Abstract: An analysis method for optimizing number and position of screws used in long bone (fracture fixation) surgery, including the following steps. Perform a CT scan on a surgical patient to obtain a medical image to build a long bone 3D model. Analyze an X-ray image to obtain a long bone fracture condition and a bone quality condition. Select a bone plate 3D model from the model database. Import the bone plate 3D model into the long bone 3D model and set an initial fixation position of the bone plate 3D model. Instruct the first artificial intelligence to comprehensively analyze the conditions to automatically select alternative solutions in the model database. Then, use a computer-aided analysis system to analyze the stress distribution of the alternative solutions, and a first preferred solution is obtained through simulating analysis, thereby excluding incorrect or ineffective surgical plans to reduce the analysis time and patient wait time and increasing the surgery success rate.

Abstract: A wheel chair with urinal device includes a wheel chair a cushion connected thereto and the cushion has a hole. A drain pan with a slanted bottom wall is removably located beneath the cushion and a drain hole is defined through the lower front end of the slanted bottom wall. Multiple outlets defined in the support frame communicate with the space above the slanted bottom wall. A box is removably attached to the rear side of the backrest and has a collection unit and a cleaning unit received therein. The cleaning unit provides detergent to clean and flush the waste in the drain pan and collected in the collection unit. The user activates and controls the cleaning unit by operating a cleaning switch on the armrest.

Abstract: A pair of pants for a person with limited mobility, which is convenient for the person sitting in a urinal chair to urinate, includes a pants body and a zipper. The pants body has a waistband, two pants legs, a crotch and an opening defined between the waistband and the crotch of the pants body. The zipper has two rows of teeth at two opposite edges of the opening and a zipper head moving along the two rows of the teeth. The zipper head is pulled to move upwardly from the crotch to the waistband of the pants body to open the zipper. Therefore, when the zipper head is positioned at the waistband of the pants body, the zipper is fully opened; in contrast, when the zipper head is positioned at the crotch of the pants body, the zipper is fully closed.

Abstract: A computer for aiding determination of Obstructive Sleep Apnea (OSA) includes a storage device storing with a medical image and a central processing unit (CPU). The CPU executes a method for aiding determination of OSA. The method for aiding determination of OSA includes the following steps. The medical image is obtained. An upper airway model is established. A narrowest cross-section and a nasopharyngeal boundary cross-section are defined in the airway model. A cross-sectional area of the narrowest cross-section and a cross-sectional area of the nasopharyngeal boundary cross-section are calculated. A stenosis rate is calculated according to the cross-sectional area of the narrowest cross-section and the cross-sectional area of the nasopharyngeal boundary cross-section. The stenosis rate is provided. In addition, in the method for aiding determination of OSA, a respiratory flow field simulation may be further performed to obtain and provide a flow field pressure distribution of the upper airway model.

Abstract: A urinal chair includes a chair body and a urinal device. The chair body has a seat supporting frame defining an open seat area. The urinal device includes a top open drain pan, a cushion, a container and a cleaning device. The drain pan is supportably mounted upon the seat supporting frame of the chair body to fit in the open seat area of the chair body. The drain pan is slanted to drain toward a drainage aperture therein. The cushion is fit over the drain pan and defines a hole to permit drainage through the cushion to the drain pan. The container is disposed under the drain pan to collect liquid from the drain pan. Moreover, the cleaning device includes a cistern and a spout connected to the cistern. The spout is directed toward the drain pan for cleaning the drain pan with water stored in the cistern.

Abstract: A computer for assisting in determining the strength of fixing a craniofacial surgery patch comprises a storage device for storing a medical image and a central processing unit, the central processing unit carry out a method for assisting in determining the strength of fixing a craniofacial surgery patch. The method includes obtaining a medical image; establishing a skull model according to the medical image; receiving a patch setting command, and disposing a patch model on the skull model according to the patch setting command; generating an internal grid mesh data of the skull model disposed with the patch model; executing a biomechanical simulation of a patch structural strength according to the skull model disposed with the patch model, the internal grid mesh data and a boundary condition; and providing a stress distribution, a strain distribution or a displacement distribution of the patch model to assist in determining.
