VOLT BANK

Construction of a safe operating system and efficient battery-charge
management for battery-equipped medical equipment

ABSTRACT:This study describes a battery-charging rack (VOLT BANK) that was developed and implemented inour institution. A charge-control box was created with various functions, and a special rack wasincorporated. In the 100V cutoff function, when the batteries are fully charged, the equipment
automatically turns off the power supply of 100V, in the order that they finish charging. A maximum of
36 medical devices can be simultaneously charged and stored. This rack was thought to enable
construction of a safe, smoothly operating system for battery-equipped medical equipment andefficient battery-charge management that prevents overcharge and electrical discharge.

VOLT BANKVOLT BANK was developed jointly with TAKASHIN Co., Ltd. and enables efficient batterycharge management that prevents battery overcharge and discharge. The power is turned off tothe fully-charged equipment without unplugging it, and overcharging of batteries is prevented.
In addition, the liquid crystal display panel has marks that charging is Orange, completion isGreen and White blink after charging is complete to clearly show priority assignment.

IPCD Tester

This tester earned awards for excellence in JACE 2014 congress�
ABSTRACT:
Inspection for ensuring the safe use of medical devices is an essential part of patients’ safety in clinicalsettings. Only basic checking appearance and operations of the intermittent pneumatic compression
devices (IPCD), which can prevent venous thromboembolism, had been conducted, but any specificinspections did not. Although the vinyl tube that connects the device to pressurized sleeves worn on thelower limbs can break easily, there were no ways to conduct a thorough leak check of the tube in demand.
We co-developed with a local manufacturing company an intermittent pneumatic compression device
tester (IPCD tester) that can assess the air pressure value in the IPCD compressor circuit and alert the airleak. The IPCD tester can also assess the tube and its connector. We used this tester and screened troublesof the IPCDs in our hospital. The tester could detect failures of the IPCDs easily and consequently werepaired them. The tester thus prevented the broken IPCDs to be supplied to patients.

IPCD Tester

In the past: Only basic checks of external appearance and operation checks.
Introducing IPCD tester: Consequently, efficiency measurement, assessment of systemerrors, and testing of the easily broken sequential compression device (SCD) connector
tube in intermittent pneumatic compression devices is now possible.

compression device dedicated tester. Jpn J Medical Instrumentation: 2017

Introducing IPCD testers to existing tests allows detection and repair of issues in intermittent pneumatic
compression devices. Lending out of broken devices can be avoided before it happens, thus reducing theincidence of thromboses and embolism in patients.

Shoe Cover Catch & Throw

copyright-free materials

ABSTRACT:
Automatic shoe cover dispensers apply shoe covers quickly and hands-free in a clean room or operating
room while the user remains standing. Because of its hands-free operation, an automatic dispenser ismore sanitary and hygienic, and enables rapid and easy application of a shoe cover in about 5 seconds.
In Japan, however, the act of removing shoe covers is still performed by hand even though preventing
exposure of the user's skin and mucosa during removal is equally or even more important than duringshoe cover application. Therefore, a device that can remove and dispose of shoe covers automatically isneeded to protect medical staff from dermal and mucosal exposure to blood and body fluids adheringto the shoe covers. Therefore, as part of the development of medical devices through collaboration
between medicine and industry, we clinical engineers have collaborated with a local company todevelop a prototype for an automatic shoe cover removal and disposal device (Shoe Cover Catch &Throw) that reflects and prioritizes the practical needs of the operating room.

Shoe Cover Catch & Throw(Prototype model)With external dimensions of 400×550×350 mm (width x depth x height) and a weight of
15 kg as the main specifications, we constructed the Shoe Cover Catch & Throw device
comprising a stainless steel frame; fingers; a disposal arm; power plug (input power: AC100V, 50-60 Hz); multiple motors, gears and chains; optical sensors (2 sets of shoe detectionsensors, one set of heel detection sensors); a control circuit; and a refuse receptacle.

Shoe cover catch & throw

The development of the shoe cover removal and disposal device enables automatic, hands freeremoval and disposal of one shoe cover in about 5 seconds while the user remains standing. By
using a mechanism that does not contact the shoe when the cover is removed, this device can beused for a wide variety of footwear from sneakers with heels to slippers without heels. The Shoe
Cover Catch & Throw protects medical staff from dermal and mucosal exposure to blood and body
fluids, and can be expected to reduce nosocomial infections.
