摘要:

This article reports the results of a clinical and electronic evaluation of a portable electrocardiograph. The clinical evaluation was carried out in a regional cardiological unit on both inpatients and outpatients under conditions essentially similar to normal daily routine. The electronic evaluation was conducted according to the recommendations of the American Heart Association.

摘要:

A stored program control system is described for the acquisition of evoked potential (EP) data. It is a small, portable and flexible system with a variety of input and output possibilities. The system presents a low cost solution to the problem of acquisition of evoked potential data. A novel method of converting and reducing sixteen channels of EEG analogue data to their digital equivalent is shown. It is adaptable for the inter active control of experiments and is sophisticated enough to deal with the complexities of experimental control as well as data manipulation. One of the major advantages of the system is that both the sequencing of the functions and their detailed make-up can be readily altered by programming to meet the individual requirements of any given situation.

摘要:

This is the second of three articles in which the present state of joint replacement will be reviewed. The first article was concerned with the historical development and with features common to ail joints, such as the materials and manufacturing techniques now used. The second describes representatives of the designs now used at the various joints which are replaced in clinical practice, and the third will discuss the problems now apparent and the trends in development and practice.

摘要:

The performance of a total hip prosthesis is considered in terms of reliability. The causes requiring removal of the prosthesis are considered and methods of avoiding these difficulties are outlined. It is pointed out that most attention must be focused on the areas of low reliability. The goal of increasing prosthesis lifetime must be shared between the surgeon and manufacturer.

摘要:

The use of an effective walking appliance enables a paralysed patient to achieve useful mobility. If, however, he is unable to sit down and stand up while wearing the appliance, its usefulness is much reduced as he is prevented from using his wheelchair. This paper records the results of research into this problem and gives details of a relatively straight forward solution.
