Tuboovarian abscess and the intrauterine device (Maizlin Spring)
American Journal of Obstetrics and Gynecology, 19732 case histories of severe pelvic infection and tuboovarian abcesses associated with use of the Majzlin Spring intrauterine device are presented. A 30-year-old parous white woman and a 25-year-old parous black woman were admitted to the Brooklyn-Cumberland Hospitals on separate occassions with a history of prolonged fever diarrhea pelvic pain and ...

Implementation of CAM physiotherapy device with a virtual spring
Computers in Biology and Medicine, 2008Continuous passive motion (CPM) and continuous active motion (CAM) physiotherapy devices are commonly used to promote rehabilitation of damaged synovial joints. A CPM/CAM device with no resistive CAM-type components is presented. In the CPM mode the electric motor functions conventionally, but in the CAM mode, intelligent use of the motor simulates ...

Effectiveness of the Majzlin spring intrauterine contraceptive device
American Journal of Obstetrics and Gynecology, 1972Abstract Since March 1967, 3,687 first insertions of the Majzlin spring were performed at the State University of New York Downstate Medical Center Family Planning Clinic. Seven different forms of this device, with different degrees of flexibility, made of wire gauges varying from 0.010 to 0.020 inches in diameter, were used. The 14T device made of a

Development of vibration control device with changeable spring constant spring
International Journal of Applied Electromagnetics and Mechanics, 2014Springs are used for various purposes, particularly for vibration control and the removal of machines. However, the use of a spring generates high amplitude at the resonance point; therefore, it is difficult to eradicate vibration from all frequency bands.

Measurement and modeling of an electromechanical spring reverb device
The Journal of the Acoustical Society of America, 2022A spring reverb is an electromechanical device used to artificially reverberate an audio signal, i.e. to impart a sense of spaciousness to the audio signal, as if the sound were being emitted into a reverberant acoustic space. The device consists of a number of helical springs set into motion by electrically driven magnetized beads, with the elastic ...

Spring over muscle (SOM) actuator for rehabilitation devices
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005For people affected by stroke, frequent physical therapy has been shown to be an effective form of rehabilitation. To this goal, several home therapy devices have been developed. Many of these devices may benefit from the use of a bidirectional pneumatic muscle actuator.

Spring Suction Device for Pulmonary Needle Aspiration Biopsy
Radiology, 1971A simple spring attachment to provide automatic suction during percutaneous needle lung aspiration biopsy is described. The spring device provides continuous suction while the needle and syringe are rotated to core the lesion. Its use is suggested to facilitate manipulation of the needle, particularly for those who may have difficulty in maintaining ...

Review of Scientific Instruments, 2002
We describe a simple device for the calibration of atomic force microscope cantilevers and micromachined springs. The device measures the deflection of the cantilevers in response to known forces that are derived from calibrated macroscopic cantilever springs. We have used the device to determine spring constants from several N/m to tenths of μN/m.

A Spring-Loaded Constant Force Exercise Device
Advances in Bioengineering, 2001Abstract Bone mineral density loss has been observed in astronauts who have spent a significant amount of time in a micro-gravity environment [1]. The lack of mechanical stress placed on the bones while in this environment is a major factor in the decrease in bone mineral density.
