Dear insert hospital here,
The one thing most hospital patients lack is a sense of pride. After researching “My spoon”, a device developed by Secom Inc., I have been able create an invention of my own that is able to fix this dilemma. My invention was built to give back some pride, to the people who have been deprived of motion in their arms or legs, otherwise paralyzed. Whether it was a car accident, or an illness, once they become dependent on others for simple jobs such as getting a soup can from the top shelf or even getting fed like a child, a certain cloud of shame drifts above them spinning them into a storm of depression. To help keep your patients in top condition I suggest you buy my invention. DOC.

First of all I am guessing you would like to know what exactly my invention does? Well as I said before, it was built to help the paralyzed gain their pride back as well as keep them from falling into the dark storm of depression. More specifically it was built to help the handicap feed themselves using a remote controlled arm that is fixed on to a small cart. The arm is controlled by a joystick placed near the chin. Just like the older models it works in three ways manual semi-auto and full auto. During manual the user controls the arm completely, semi auto is when the mechanical arm picks up the food but the user brings it to his or her mouth. Unlike the older model the cart can be programmed to travel from room to room as a daily commute either feeding patients or giving the their medicine. Also unlike the original the user has a selection of 2-3 types of food in the machines body, which can keep it warm or cool. My machine also includes a tube type straw connected to a small tank inside DOC, just fill up with the desired drink.

If you were strapped into a chair, seeing your loved ones cry over you while being hand fed, I am guessing that you would at least be slightly depressed. To keep the patients from getting too depressed I have created D.O.C. Depression, mainly effects the mind , but also can harm the body. Sleeping disorders, cramps, pains in the lower back, neck and joints are all part of being depressed. Since hospitals are supposed to keep their patients safe don’t you think it would be a major advantage to buy this mechanical wonder.

One of questions you may be faced with is price. True, DOC is no $19.99 T.V. offer, however my device is more like an investment. By feeding patients, giving them their meds , and even pass out memos. You could save a bundle of money since you wouldn’t need to hire as many nurses.

To make sure no one is injured by the machine, it works on low power. It also stops at a pre programmed position in front of the mouth .

One of the best things about this devise is that is that it’s a snap to learn. Basically, if you now how to work a computer you know how to work this machine. All you do is you the is use touch screen to wirelessly connect it to your computer and type in instructions how to get to each the room, and what to do there.

This is my invention and I hope the you will make smart chose and buy my invention. It’s a great investment, it is extremely safe, user friendly and it will greatly improve the health of your patients. Engineer in training Carlos Cruz III

My spoon

I don’t know about you but, when I wake up in the morning I pour myself a mammoth sized portion of icy cold cereal. Then I grab the biggest spoon in the drawer, and take in a mouth-full that would put a whale to shame. The thing is though, that I’m able to use my own two hands, were as somebody with, quadriplegic or paraplegic(Which is when you can’t use your arms or legs) would have to stay in bed, stare at the wall or sit on the side, to wait for somebody to pick them up. Now if that isn’t bad enough, they even have to be fed by their friends and loved ones, much like a child would. However, thanks to the inventers at Secom Inc. they finally are able to gain some of pride back. This mechanical device that has been able to make this dream possible is called My Spoon.

The first question you may be asking yourself is probably “What does this device do?” Well, imagine your arms and legs were strapped onto a chair. I am guessing it would feel pretty odd not to be able to use any of your limbs. Now picture your self trying to do your daily activities, such feeding your self. Try to picture that nightmare coming to life. Believe it or not it actually happens to some people. Inventers at Secom Inc. have notice the shame of having to be fed by your mom or dad, so they invented “My Spoon”. This device lets people who can’t use there arms feed them selves.

My Spoon is basically a remote control arm with a fork at the end. It uses a joystick and a unique tray that is separated in four places, to feed the handicapped. The individual being fed, firsts picks one of the four quadrants in the tray, then a food item. Next, using the controller, the person will navigate the fork to his or her mouth. This mechanical device, other then manual, also works in semi-auto, and full-auto. During semi- auto he or she has the capability to choose one of the four compartments, however the machine selects the food item and brings it to his or her mouth it self. It also uses a variety of control systems. To control “My Spoon” a joy stick is placed near the user’s chin or within a length that he or she can control. There are two types of joy sticks, standard and re enforced. The standard joystick is mainly used for people who are able to control it properly. The reinforced joystick is used if the operator can not use it accurately.

Although this seems like a very convenient piece of equipment, it actually has a couple of problems that may prevent it from assisting the user. One of those problems would be the fact that if the person has a difficulty maintaining an up right position, basically any thing under a 60 degrees and he or she would not be able to use it. Say you became paralyzed from a spinal cord injury don’t you think it would hurt a bit to sit up right for a while. Another dilemma, is if the operator has problems with his or hers motor skills or if he or she has trouble, seeing devises arm.

In early phases of neuromuscular disease, patients are either free of respiratory symptoms or have exertional dyspnea not explained by obvious obstructive or restrictive lung disease. Physical examination may be negative because generalized muscle weakness does not correlate with the degree of respiratory muscle involvement. When the diaphragm is involved, one may detect the absence of outward excursion during inspiration or even paradoxic inward inspiratory movement of the abdomen on one side. A substantial loss of respiratory muscle strength is typically accompanied by little or no change in spirometry or arterial blood gas composition. Other characteristics are moderate loss of maximal voluntary ventilation and an increase in residual volume, yet PImax and PEmax may be as low as 50% of the predicted value. In more advanced neuromuscular disease, patients may have severe symptoms if the onset is acute or subacute; however, patients with chronic advanced generalized muscle weakness do not exercise and, therefore, may not be breathless. Many patients with advanced neuromuscular disease present with daytime somnolence as a manifestation of a sleep-related breathing disorder. Physical examination may reveal generalized muscle weakness and difficulty with speech or swallowing. Signs specific to respiratory involvement include tachypnea, use of neck inspiratory muscles and abdominal expiratory muscles, and loss of chest-abdomen synchrony. Sometimes paradoxic bilateral inward movement of the abdomen with inspiration is overt. Patients may be unable to cough effectively, have scoliosis, and lack a gag reflex. At this advanced stage, PImax and PEmax are lower than 50% of the predicted value, and the vital capacity is reduced. Maximal voluntary ventilation increases, and residual volume increases further. Patients may not yet exhibit CO2 retention during the day and may even have a low PaCO3. A sleep study may reveal significant hypopneas with severe desaturation and hypercapnia, especially during REM sleep. It is important to be aware that overt ventilatory failure can occur abruptly and that measurement of arterial blood gas composition is not a reliable indicator of this danger. Therefore, it is critically important to heed clinical phenomena, such as increasing dyspnea and tachypnea, and symptoms of sleep disturbance, such as morning headache and daytime somnolence. Physicians should make serial measurements of VC and respiratory muscle strength in patients considered to be at risk for further deterioration.(ABSTRACT TRUNCATED AT 400 WORDS)
