Back in 2019 few imagined what 2020 would bring.  Fewer yet could predict the position face masks and face coverings would play in the politics and prevention of the Covid 19 pandemic.

After a considerable dearth in availability, supply of face masks are slowly returning to the market place. Global demand however remains high, resulting in an overall global shortage.

New to us, perhaps, but face masks date back to the 17^th century plague, and the more familiar ‘hospital surgical mask’ rapidly approaches its centenary.

So what is 3ply mask?

3 ply essentially means 3 layers. A 3 ply mask consists of an outer and inner non-woven fabric layer with a middle filtration layer made from a polypropylene polymer, typically referred to in the industry ‘melt-down’. The meltdown layer prevents microbes from entering or exiting the mask, and it is the global shortage of this material which has resulted in higher costs of production and higher onward costs in the industry.

Are all 3 ply masks the same?

Whilst the principle of a 3ply mask is the same – to prevent the entrance and exit of microbes, some do this more efficiently than other.Any commercially available mask should have undergone testing (by sample selection) to determine how well in filters, how it copes under physical pressure, the degree to which blood penetrates and a microbial cleanliness test.

For the purpose of comparison, a key differentiator between the performance of masks we stock at MediBargains is how well the masks filters.

Below is a table of the various testing standards used and how well the masks perform.

There are other masks available but these are the types we have decided to offer to provide a range of protection based on need.These are just our recommendations and this does not constitute medical advice.

Urinary catheterisation is a medical procedure used to drain and collect urine from the bladder.

What is a catheter

A thin, flexible tube called a catheter is inserted into the bladder,

usually along the tube through which urine naturally passes (urethral catheter), 

or through a hole in your abdomen directly into the bladder (suprapubic catheter).

The catheter usually remains in the bladder, allowing urine to flow through it and into a drainage bag.

Why is urinary catheterisation needed?

A urinary catheter can be used on a short- or long-term basis.

Short-term catheterisation

Short-term catheterisation may be needed to remove urine from the bladder for a short period of time 

if there is something stopping you emptying your bladder in the normal way.

For example, if the bladder cannot empty due to an obstruction (blockage), 

or if it is unable to generate enough force to propel urine down the waterpipe.

If the urethra has become blocked, it may be due to scarring (stricture), prostate enlargement  or, 

rarely, a stone. A catheter will be fitted until the underlying condition can be treated.

Short-term catheterisation may also be used in preparation for some types of surgery, 

such as operations on the womb or ovaries and procedures involving the large bowel. 

It may also be used for other operations where a long period of recovery is anticipated.

Other situations where a catheter may be used include during childbirth (to drain the woman's bladder), 

and to clear the bladder of any blood clots and debris following an injury to the bladder or after surgery to that area.

Long-term catheterisation

A urinary catheter may be needed for a long time if it's not possible to treat the underlying condition 

that's preventing the bladder from emptying naturally.

Long-term catheterisation can be used when a person is confined to bed and is too weak

to go to the toilet. It is also sometimes used as a treatment for urinary incontinence when 

other types of treatment have failed.

If a person is unable to empty their bladder because of bladder weakness (detrusor hypocontractility) 

or nerve damage (neuropathetic bladder), long-term catheterisation is possible treatment option.

If you require urinary catheterisation for a long time, you may be trained to insert a catheter 

when needed. This is known as self-catheterisation and involves catheterisation for a short period 

to allow the bladder to empty before the catheter is removed. This is likely to be carried out several 

times a day and avoids the problems associated with permanent catheterisation (see below).

Other uses

In some cases, catheters can be used to obtain a clean urine sample to test for bacterial infections. 

This is a sample that has not been contaminated by bacteria from your hands or genitals.

A catheter can also be used to deliver medication directly into the bladder. 

For example, chemotherapy medications used to treat cancer of the bladder. 

Types of catheters

There are two main types of catheter. They are:

• an intermittent catheter - where the catheter is temporarily inserted into the bladder and removed once the bladder is empty
• an indwelling catheter - where the catheter remains in place for many days or weeks and is held in position by a water filled balloon in the bladder

Many people prefer to use an indwelling catheter because it is more convenient.

However, indwelling catheters can be complicated by problems such as bladder spasm, infection,

blockage and leakage around the catheter. These problems are reduced if intermittent catheterisation is used.
