STERILE DISPOSABLE LARYNGOSCOPE BLADE SHEATH

Abstract: The inside of the sheath is hollow (1) so that it can be inserted on all the common standard laryngoscope blades eg: Allyn, Miller, Penton, Phillips, Scott, Wisconsin etc. The width of the sheath is wider than the common blades and the shape (3) of the sheath is curved, so that the tongue can be lifted stabily without slipping. There is a hole (5) in the bottom of the sheath so that the light of the laryngoscope blade can shine through the hole and the trachea can be seen. This makes the intubation easier, smoother and quicker, the complications of intubation will decrease and unnecessary death will be avoided. Because this sheath is disposable after each single use, cross infection will be prevented.

Description: STSRILE DISPOSABLE LARYNGOSCOPE 3LABE SHEATH BACKGROUND 0? THE INVENTION /hen the patient needs oral intubation the only tool on the market today, to assist this procedure, is laryngoscope. The function of it is that the laryngoscope blade hold the tongue and lift up the epiglottis so that practitioner can see the trachea and able to insert the oral endotracheal. tube underneath the laryngoscope blade into the trachea. The problem is that all those laryngoscope blades on the market are narrow and only can hold half of the tongue, so that it is very hard to make the tongue stay stably on it. Just like a person walk on the iron wire in the air. If the patient is cardiac or respiratory arrest the critical period is four minutes and lot times the tube could not place into the trachea in time and the patient will be suffered by brain damage. I worked in hospital over 15 years. In 1982 I realized that these problems have to be corrected. From that time on I was thinking to invent something. In 19δ3 the idea became clear and the new invention will corrected those problems. THE PURPOSE AND THE FUNCTION 0? THE INV3NTI0N This new invention can overcome above mentioned drawback of the intubation. This steriled disposable sheath would be inserted by common standard laryngoscope blade eg: Allyn, Miller, Phillips, Penton, Scott, Wisconsin etc. Because the shape of the sheath is curved, the width is wide so that it can hold up the whole tongue on it stably without slippery. The tongue can be lifted up easily. There is a hole in the bottom of the sheath so that the light of the laryngoscope blade can through it and the trachea can be seen clearly and the endotracheal tube can be inserted quickly, easily and . ^ smoothly without difficulty. And because this invention sheath is steriled and disposable for single use so that it can prevent cross infection. S.UI--1Ϊ.---Y OF THE INVENTION Those 1 r_πι oscope blade on the market today are too narrow to noli up the v. ole tongue without clippery. The new invention can overcome all those drawbacks of the intubation. 1. This invention is a laryngoscope blade sheath which the common standard laryngoscope blades eg: Allyn, Ililler, Penton, Phillips, Scott, ' /isconsin etc. can be inserted into the sheath. 2. The width of the sheath is wide enough to hold up the ..-hole tongue. 3. The sheath .ire curved so that it can hold up the tongue stably without slippery. . There is a hole in the bottom of the sheath, so that the light of the laryngoscope can through it and the trachea can be seen. 5. The sterile sheath will cover all parts of the blade so that it can keep away from contact any part of the mouth, β. After single used the 1 ; ryngoscope blade sheath can be disposable so that it can prevent cross infection. So this new invention will accomplish the followings: 1. easier smoother and quicker intubation. 2. prevent cross infection. 3. decrease complication. . aviod unnecessary death. ' "THE DISCRIPTION OF DRAWING Fig. 1. is an oblique projection of the top plan view, front plan view of the invention. Fig. 2. is bottom view of the invention. Fig. 3» is laryngoscope blade inserted in the sheath. EXPLANATION OF THE DRAWING As can be seen by reference to Fig. 1. is the laryngoscope blade sheath in oblique projection of the front and the top plan view. 1. is the entrance of the sheath, through here the common ■laryngoscope blade eg: Allyn, Miller, Penton, Phillips Scott, -Wisconsin etc. can be inserted into the sheath. 2. is the edge of the sheath. 3. between the c-dge and the body is curved in, spoon like so th_.t it can hold, the tongue stably without slippery. ■+. is the body of the sheaih. As can be seen by reference to Fig. 2. is bottom view of the . sheath. 5. is the hole through which the light of the laryngoscope blade can be seen. 6. The groove in the bottom as a guide line for the endotracheal tube to be inserted easily and smoothly. As can be seen by reference Fig. 3- is the laryngoscope blade inserted.in the laryngoscope blade sheath. 7. is the laryngoscope blade.. 8. is the handle of the laryngoscope.
