Over Toilet Aid – Transforming Home Health Care for People with Limited Mobility

February 4, 2022

Over Toilet Aid sample img For so many years, people with mobility issues like the seniors and patients receiving healthcare have been using different assistive devices to make toileting easy, safe, and hygienic.

But today, we are going to talk about toilet aids and how they can transform home health care and improve the quality of life of people with reduced mobility.

What is an Over Toilet Aid?

Designed to make the process of toileting safe and increase user independence, toilet aids are usually made from a non-corrosion and reinforced aluminum frame with adjustable legs and raised armrests to assist the user in transferring on and off the stool.

Also, most models of toilet aids have durable non-slip feet to provide a firm grip and stability in wet bathrooms or conditions.

Benefits of Over Toilet Aids

The use of this assistive device has proven to be very beneficial for people who could not use the toilet on their own without assistance.

Here are some of the benefits of toilet aids.

Offers Extra Layer of Security and Stability

The first is for safe toileting. We know that as people age, their strengths are no longer the same when they are young. Their legs become weaker and unsteady. Getting on and off the toilet safely and comfortably can be challenging. And the risk of falling is very high.

But with the help of toilet aids, toileting becomes safe and easy because of the stability and support that the device provides.

The adjustable and sturdy features of the device offer an extra layer of stability and security for people like the elderly who are prone to falls.

For bariatric users, the reinforced aluminum frame of most toilet aids can accommodate this type of patient.

Increase Toileting Independence and Privacy

Regardless of our age and health conditions, we all have the right to preserve our dignity in doing a personal task like toileting. These toilet aids not only promote toileting independence but also provide some privacy to people with mobility issues.

Some types or models of toilet aids have features that allow the users to clean themselves without the help of their caregivers.

Also, other models like the split seat over toilet aid have new seating that provides full access to all the body parts of the patient, and there’s no need to stand off the chair to have their body parts cleaned.

Improves Quality of Life

Toileting is a part of our daily life regardless of our age and physical conditions. But for people with limited mobility, this task can be a bit risky and challenging.

With the availability of these assistive healthcare devices, people with reduced mobility can once again have control of their life even just by doing this task. And eventually can help improve their quality of life.

Summary

With all the benefits and added features that toilet aids offer, getting on and off the toilet can be safer and less complicated for those who might need some assistance. Whatever be your circumstances and specific needs, there are a lot of toilet aids that can help you.

The first acknowledged use of waterjet cutting technology in the medical sphere was when it was utilized for cutting bodies and as an indispensable tool for endoprothesis dental surgery. One of the advantages of the water jet method of cutting over other traditional cutting methods is that it does not involve the use of or generate heat, pressure, or sound. Hence, one good reason why it is ideal for dental and medical surgery.

Another good thing about it is that it lessens the need for anesthesia, promoting healthier dental tissues when applied for dental procedures. The tendency of the waterjet method when utilized for a dental procedure is to leave a relatively dry work area. This works to the advantage of a dental specialist who needs to carry out a subsequent hole filling because it mitigates micro-cleavage risks and jagged teeth.

The water jet technology can be used practically in traumatic wound cleaning. Skin wounds of this type and their healing process are codified using the abbreviation, “TINE”. This stands for tissue necrosis, which indicates dead skin tissue.

Damaged and dead tissues, including the inadequate supply of blood, need to get removed. As for the bacterial burden, it should not go greater than 100,000 bacteria/g. The use of waterjet and making it work as a scalpel will pave the way for healthier tissue as opposed to the use of traditional methods. Known as the versajet technology, this is also highly recommended when you need to clean wounds and clear them from foreign elements including silicone gel brought about by implants, sand, and earth. They could otherwise get integrated into the skin’s healing process, thereby creating a tendency to create and leave a traumatic tattoo.

Waterjet cutting technology has also found practical application in skin graft degreasing. Liposuction is another field where this technology is likely to receive a practical application. Water jet liposuction (WJL) is a qualified non-edema method, maximizing the old method’s benefits.

WAL or water jet assisted liposuction makes use of a thin fan-shaped stream of water. By this measure, the process is made able to release fat cells while saving the nerves and blood vessels. Fat cells will then be removed from where they got accumulated, only to get drifted out by saline. There is a handful of benefits to enjoy from WAL, and they are as follows –

It offers greater accuracy of results, sans contour changes, and edema.
Improved patient mobility of patients
Optimal access to the treated area
Improved patient comfort
Postoperative wound infiltration is made possible in less than 24 hours.
Amount of patient medications is reduced

Moreover, the hydro abrasive jet is also considered as a very indispensable dermatology tool used in the removal of dead skin cells. Water flow will be dosed with several kinds of drugs, included here would be anesthetics, to help in the removal or alleviation of pain; antiseptics, for disinfection purposes due to the violation of the skin integrity.

Another water flow application in medicine is the microwave waterjet cutting scalpel. This technology is normally used for the resectioning of tumors. When you combine a jet system and the microwave scalpel technologies, the result of the melding is this kind of technology that allows flow control directly into the saline, then directing it towards the workspace.

Microwave waterjet scalpel lowers the odds of perceived microwave radiation risks to occur. Its direct usage in medical surgery brought out many benefits and advantages that are not to be seen with other traditional methods. It utilized sensitive sterile saline pressure to be able to resect tissue. The applicator is made up of a nozzle jet with a 120-micrometer diameter.

What Do We Need to Know About Yagi Antennas?

Yagi antennas are also known by another name, Yagi Uda antennas. They are the same directional antenna technology consisting of several parallel elements in a line.

The yagi type of antenna is named after its two Japanese national inventors, Hidetsugu Yagi and Shintaro Uda. It usually comes with a reflector element and normally this is slightly longer when compared to that of a driven dipole. Now, as for the directors, they are a bit shorter.

The radio waves, which can be traced as coming from the driven element, are being absorbed and reradiated by the parasitic element with a different phase. This will help modify the radiation pattern of the dipole.

The waves that are coming from the multiple elements will create interference, paving way for the coming of enhanced single direction radiation. This helps a lot in increasing the antenna gain as opposed to just having a simple dipole.

Basics of the Yagi Antenna Theory

If you are keen to know and want to understand the Yagi theory and what it is like, good background info on the phases of flowing currents is essential here.

The yagi type of antenna and its parasitic elements work by re-radiating the signals they have in a different phase to help in matching that of the driven element. This makes it possible to have that signal reinforcement occur in some directions but would be canceled out in others, instead.

While there are a few antenna Yagi elements that are not directly driven but are rather picking up the driven element’s power, all these extra elements are qualified as just parasitic elements.

The design in which the Yagi type of antenna comes in has its own set of limitations — the additional element’s power is not driven directly. There is no guaranteed way that the induced current phase and the amplitude can be controlled or managed in any way. They are dependent upon their spacing and the length between the dipole or the driven element comes in.

What does this signify then? This only goes to show that canceling in one direction is not at all possible. Nevertheless, one can still possibly obtain an elevated degree of reinforcement in one direction and this should earn you still a high level of gain.

Additionally, this also brings a high cancellation degree in another, providing you with a good front to back ratio. Yagi antennas are highly capable of providing useful gain levels.

To have that required phase shift, it’s essential to come up with an element that can be made, falling as either capacitive or inductive. The type of reactance that it should come with is likely bringing along as well a different effect.

Inductive:

Once a parasitic element is transformed so they become inductive, the tendency of the induced phase will reflect the power but it will not be in close range to the parasitic element. This will make the RF antenna radiate an increased level of power, only that it is in the opposite direction of the parasitic element. An element behaving this way is referred to as the reflector.

Capacitive:

If you make a parasitic element as capacitive, the induced currents will be in a phase where the power of the whole antenna radiated will be towards the parasitic element’s direction. The element displaying this kind of behavior is known as the director.

You can make it capacitive, but you will have to tune it above resonance level. It is made possible when you add capacitance to the element, which has to be in a capacitor form. Or by having it 5% shorter when compared to that of the driven element.

By deliberately adding more directors, it will tend to increase the antenna’s directivity. This will increase the gain but will be inversely proportional to the beamwidth which is reduced. The successive director’s length will be reduced slightly.

Waterjet Cut Machine and Its Role in Advancing Medical Work

Should we be able to sustain the current wave of progress and development in the technology working behind water jet cutting machines, there is a good chance that abrasive waterjet cutting applications will be advancing even further in the medical parts manufacturing sector.

To give you a glimpse of what is happening now, for instance, the development of micro-miniature waterjet nozzles has already started. It is expected to set the cost benefits of waterjet cutting and productivity available to a wider spectrum of medical applications. The majority of which though would be involving micromachining of small components.

When it comes to micromachining of medical components, to come up with top-caliber quality, the use of extremely precise water jet streams is of paramount importance. However, if you try to shrink the sizes of traditional waterjet nozzles to make them generate thin, precise streams, you’ll come across 2 major challenges. The vast majority of waterjet manufacturers have struggled with this for the longest time.

The use of an extremely fine garnet will help in producing an effective narrow stream. Unfortunately, the use of small particles of garnet runs the risk of clumping. Moreover, you’d probably have a hard time in getting yourself a smooth flow of materials that your cutting process might require.

Clumping usually occurs in the machine feed tubes. If this occurs, it may pave the way for a non-uniform or intermittent stream and this can result in skipped cuts. Sometimes it can also wreak damage to the part material being worked on.

Besides the non-uniformity of cuts wrought out by the challenges found in abrasive particle feeding, mixing tubes and small nozzle orifices can produce a water column that can remain seated within the tubes.

The low speed fronting the abrasive waterjet stream impacts the water column surface. This can produce a backsplash and runs the risk of wetting the mixing chamber’s residual abrasive particulates or feed port entrance. The risks of clogging will continue to rise substantially if there is going to be a sustained accumulation of wet abrasives in these areas.

A good number of waterjet manufacturers resorted to a handful of different approaches. They believe that doing so would help them find their way around the non-uniform abrasive flow and clogging issues. Over the years, top manufacturers did various kinds of trial and error approach with water flushing and vacuum assist techniques. They’re in a desperate attempt to finally eradicate clogging issues and abrasive flow.

Sad to say, most of the time what they came up with are just unsatisfying results, nozzle designs were a bit bulky with multiple ports. Aside from that, there are also modifications of ejectors, connecting tubes, control software, water pumps, and other devices. In the end, these complicated systems will negate the technology’s time benefits and parts of the costs.

Why Waterjet Cutting Machine Technology?

In comparison to the various conventional metal cutting techniques we have around, abrasive waterjet systems deliver substantially higher speeds in cutting, greater ease of use, reduced amount of time in setting the system up.

Waterjet system operators only need to upload a drawing of a part, indicating already the various specifications of the material together with the required tolerances. The onboard software will then take on calculating the tool paths before it begins to carry out the cutting data.

Waterjet machines are giving the manufacturing firms catering to the needs of the medical sector the flexibility to handle the cutting of a wide spectrum of materials. Fabricating shops will just indicate the material change that is within the machine controller.

No other equipment or programming would be necessary to go from the cutting of ceramics or metals to other materials. With respect to material thickness and type, it will automatically make adjustments to the machine’s X and Y axes. By this measure, the level of productivity is maximized while sustaining the required precision.

Lastly, in comparison to a piece of stamping equipment or any other established traditional metal cutting methods, the use of abrasive waterjets necessitate you exert only a small amount of force on handling workpieces subject to cutting.

In the case of a waterjet cut machine, this allows the medical sector to cut highly delicate part features that would be either very costly to produce or just way too impossible to accomplish if you will only employ traditional machining methods.
