INVENTION OF "AN IMPROVED OROPHARYNGEAL AIRWAY" Field of the Invention :- The Improved Oropharyngeal Airway is related with the field of Medical Science, which is very commonly used in Hospitals and Clinics. Background of the Invention :- Before the Invention of the new type of Oropharyngeal Airway, the commonly used ordinary Oropharyngeal Airway had many shortcomings because of its poor design. Therefore the medical professional like doctors, nurses, compounders etc. had to take excessive precautions during their use. Besides, there was a lot of wastage of time and labour causing unnecessary trouble to the patients. Because there is only one front hole in the ordinary Oropharyngeal Airway, it allows suction from larynx only. Among the serious patients, dirty saliva or vomit etc. collects on both sides of the checks, which is cleaned with great difficulty. For this, Oropharyngeal Airway, which is attached to the mouth with he help of ordinary Leucoplast has to be removed before cleaning of the mouth is possible. After cleaning of the mouth of the patient, the Guedel Airway is again fixed with the help of leucoplast etc. because there was no other alternative. Ordinary Leucoplast or Micropore having chemicals are to be used again and again that cause change in colour of skin of patients, blisters or eruptions etc. Besides, there is also a problem of itching. While cleaning the mouth, patient's neck has to be turned repeatedly sidewise so that his mouth is cleaned or suction is done properly. Keeping in mind the foresaid problems a new type of Oropharyngeal Airway was invented. Prior Art.:- Ordinary and old type of Oropharyngeal Airway that are available in medical market have only one Front hole or suction hole. Their design and technology is of a very low standard, which has made them synonym to trouble. 2
Disadvantages of Prior Art:- Ordinary Airway have following shortcomings :- That there was only one opening in the ordinary airway that problem in suction. causes That there was danger of infection due to non proper suction and deposition of wastage on both side of cheeks and mouth cavity. That ordinary air way was fixed by Leucoplast or micropore only. That Leucoplast or Micropore have chemical so they can cause adverse effect on the skin, which were bored by the patients for long time. That shape of the prior airway was also not very nice. That prior airway caused more hardship than to relief. That in old oral airway patients have to suffer much difficulties. Because it required turning of neck during mouth suction. That old and ordinary airway was removed easily by the irritable and uncooperative patient by hand or tongue easily. Advantages of The New Invention :- The New Improved Oropharyngeal Airway will provide following advantages. That it has three openings instead of one. That it will make suction easy. That there will be no need of Leucoplast or micropore to fix by Improved Oropharyngeal Airway. That this Improved Oropharyngeal Airway is beautiful in shape. That by using this Improved Oropharyngeal Airway removing of wastage in the mouth cavity will be easy. 3
That to make it more comfortable both sides valcros is used in this Improved Oropharyngeal airway. That this airway is fixed easily while ordinary (Prior) airway was fixed with difficulty with ordinary tape. That this airway is new and more useful than old one. That by using new Improved Oropharyngeal Airway patient can turn his/her neck in any direction which ever he/she required and suction could be done easily. That patient will not be able to remove new airway despite of his willingness. Summary of the Invention :- This Improved Oropharyngeal Airway is used in the serious type of patients to keep their jaws open, and for cleaning any type of dirt present in the mouth. In addition, it can be used, if required for Ryle's Tube, Endotracheal Tube and Nebulisation. Improved Oropharyngeal Airway has been made using New Design and New Technology, because of which it is very useful and easy to use. By its use the patient's mouth can be cleaned easily and use of ordinary Leucoplast or Micropore is dispensed with. For this purpose, its design Side Suction Holes (04 & 05) slots (06 & 07) on two corners for attaching Valcros. This airway is also kwon as Oral airway are Guedel airway to the field of Medical Science. Detailed Description of the Invention :- The description of the commonly used Oropharyngeal Airway is as follows: When Oropharyngeal Airway is inserted in the mouth of the patient, it's a Harder (03) was inserted into the suction hole (02) of the base/flange (01). Airway is open on both the sides.because Oropharyngeal Airway is totally made of plastic, serious patients sometimes press it hard between their teeth resulting in its narrowing down and closing. In order to overcome this problem the Airway is provided with a harder (03) so that the patient is not able to close the Airway. Front Hole and Side Holes are useful in cleaning the mouth filled with dirty material. In patients requiring insertion of Ryle's Tube through the nose, it can be inserted in the new Airway with ease. Front hole (02) can be used for 4
cleaning the Throat and Larynx etc. While Side Holes can be used for cleaning both sides of the cheeks. Side Holes (04) and (05) can also be used for inserting Endotracheal Tube, if required. For this purpose, the side holes are made big. Through this, the patient gets air by Ventilation. T-Tube that is used for the purpose Nebulisation in asthma patients, This Oropharyngeal Airway is helpful. Nebulisation can be done easily by fitting the mouth of the T-Tube in the Front hole. Side Section holes (04) and (05) can be made in two ways as shown in Figure No. (01) and Figure No.(03) In Figure No.l, the Side Section holes have been made on the base (01) of Guedel. By this, besides carrying out Suction, there is an ease in inserting Ryle's Tube. Ryle's Tube can be inserted through side holes (04) and (05). In Figure No.(03), the side holes (04) and (05) have been made into the harder (03). With the help of these, the throat can be cleaned easily. Oropharyngeal Airway made with both the methods as mentioned above, are very useful and advantageous. On both the ends of the Oropharyngeal Airway slots (06) and (07) have been cut in flange. They can either be elongated or roundels type holes as illustrated by figure No. (02). In these slots Valcros or rope or any other fastening device (08) and (09) can be tightened or fitted. During use both the ends of the Valcros (08) and (09) can be tightened behind the neck of the patient. This way the patient is not able to force out the Guedel by either using the force of his tongue or by using his hands. Besides the use of Valcros has another advantage; the chemical coated Leucoplast or Micropore etc. are not be used over the mouth of the patient, the use of which causes different types of inconvenience to the patient. For example, at times the colour of skin changes or there is eruptions or blisters. Besides in the event of perspiration or presence of water, the Tape or Micropore gets detached or its own and falls out. The use of Valcros helps to get rid of all such problems. At the end portion of the Oropharyngeal Airway, there is a hole, which has been shown by the serial No. (11). Front hole (02) is hollow inside, which means that it is open on both the sides like a hollow pipe. The shape of side suction holes (04) and (05) can be formed by two ways as shown in sheet number (01) and (02) by figure number (01) and (03), both kinds of structure can be made separately or can be made get together, mean to say four suction holes can be made together in one oropharyngeal airway and also can be made two suction holes separately in one airway. Any kind Leucoplast or adhesive is not be employed at the 5
mouth of the patient for the same valcros or rope or any other fastening arrangement has been provide in the device. Slots (06) and (07) can be made in shape of lengthwise cut (figure No. 01) or roundels type holes (figure No. 02) in which valcros or elastic valcros can be tightened and also can be cut with the help of scissors as required, so this improved oropharyngeal airway can also be used with or without valcros. Detailed Description of the Drawings :- Total drawing Number of sheets is three. Sheet No.(Ol) shows one kind of Improved Oropharyngeal Airway, which has been illustrated by the figure number (01). In this Figure, Side Suction holes (04) and (05) have been made from out side on the base of airway. Sheet number (02)- Shows first kind of Improved Oropharyngeal Airway which has been illustrated by the figure No.-02 in lateral view in which side suction holes (04) and (05) have been illustrated in the flange of airway with front hole (02) and it's harder (03) from out side. Valcros have been fixed by the cutting slots. Sheet No. (03) with figure No. (03) has been shown second type of Improved Oropharyngeal Airway in which side suction holes (04) and (05) are formed into and with the harder (03). As illustrated in the figure. The detailed description of Improved Oropharyngeal Airway with all parts in figure No.(01) to figure No.(03) are as follows :- 01 - Base of Guedel or flange, 02 - Front hole, 03 - Harder, 04 - Side Suction hole,05 - Side Suction hole, 06 - Slot, 07 - Slot, 08 - Valero or Elastic Valero or rope, 09 - Valero or Elastic Valero or rope, 10 - Curve Portion of Oropharyngeal Airway, 11 - End Hole of the Airway. Inventive Steps - Improved Oropharyngeal Airway can be formed with the two aspects of Invention. As Illustrated by Figure No. (01) and (03). Both the sides of Suction holes (04) and (05) can be made in two shapes. According to first aspect of the Invention side holes or suctions holes (04) and (05) can be made in the base of Oropharyngeal Airway or Flange (01) as shown in Figure No. (01) 6
According to second aspects of the Invention side Suction holes (04) and (05) are made into the harder (03) or in side the Airway, as shown in Figure No. (03) Slots (06) and (07) can be made by two shapes, In first kind, slots are made in lengthwise cut and in second kind, slots are made roundels type holes in the place of cutting slots. Both type of method are useful and fulfill their purpose. Both kinds of Valcros Elastic or without Elastic Valcros can be used to tie the Oropharyngeal Airway behind the neck of the patient. Improved Oropharyngeal Airway have been made very Smooth so that it will be easy to insert into the mouth due to its sharp buffing. Its will not give any side effect or any other problem due to its improved design and technology. 1.
