Prostate Inspection Model

Description

This model provides prostates with tumors in 4 different development periods. The 1st development: Beginning, a little big but the prostates still works well. The 2nd development: Some hard tubers can be served in the top right quadrant of prostate. It's the beginning of the tumors. The 3rd development: The tumor is proliferating, and the previous tubers become bumps. The 4th development: The prostates is all replaced by tumors, the surface become more rough and harder than before.

AED Trainer

Description

The Laerdal AED Trainer 2 offers an affordable alternative for educating the layperson and healthcare provider in the effective use of an automated external defibrillator.

Product benefits:

Educationally effective, offers all the essential features necessary for learning appropriate AED use and techniques. Affordable training through the simulation of the HeartStart FR2 AED in appearance and operation. Added instructor flexibility through unique control of the scenario selection by use of the remote control device. Flexible configuration of the device through a scenario builder program that allows the additional creation of custom training scenarios. Cost-effective operation through use of six C-cell batteries.

Product features:

Ten pre-configured sudden cardiac arrest scenarios compatible with training programs developed by internationally recognized responder programs. Remote control (optional) for manual scenario selection pause/resume function, AED Trainer 2 volume control, motion artefact, low battery or replace battery, loose electrodes connection, shock able or non-shock able rhythms and error conditions that simulate the red X in the Heart Start FR2’s status display window. Designed for use with the AED Little Anne® and AED Resusci Anne® manikins with Laerdal LINK Technology by providing student feedback as to proper pad placement on the manikins. It can also be used with any other manikin where Laerdal Link Technology is not available. Proper pad placement required in order for the trainer to advance in the scenarios when used with the AED Little Anne or AED Resusci Anne manikins.

Heat Pipe Apparatus

Heat Pipe Apparatus: Heat pipe is an interesting device, which is used to transfer heat from one location to another. The apparatus consists of three pipes, viz. A heat pipe, copper pipe and stainless steel pipe. Ail the pipes have same physical dimensions. Copper and stainless steel pipes serve the purpose of comparison of heat pipe performance. All pipes are mounted vertically with a band heater at lower end and water filled heat sink at upper end. Nearly isothermal operation of heat pipe is clearly visualized from longitudinal temperature distribution of the pipe.

SPECIFICATIONS:

1.Heat pipe – Stainless Steel pipe, 25 mm O.D., 450 mm. Long. Sealed at both ends, evacuated and filled partially with distilled water – one No. 2.Copper and stainless steel pipe of same size as that of heat pipe – one each. 3.Equal capacity heater at bottom end of each pipe. 4.Water filled heat sinks at upper end of each pipe.

Measurements and controls

a) Dimmerstat to control heat input to all the heaters – 4 amp. Capacity One No. b) A voltmeter and an ammeter to measure input to heaters One each. c) Multichannel digital temperature indictor to measure temperatures along the length of pipes.Four thermocouples are provided on each pipe. v Thermometers to note down water temperatures in heat sinks – 3 Nos.

Services Required:

230 VA.C. Single Phase supply. Floor Area = 1 m X 0.5m X 0.5 m height.
