Description

Technical Field

[0001] The invention relates to the field of laryngoscope blade teeth protection, in particular to a laryngoscope blade with teeth protection. Background Art

[0002] During use, the laryngoscope blade needs to be pressed against the epiglottis and lifted up to expose the glottis. For the elderly, their teeth are loose, and the incisors are often pried during the process of lifting the laryngoscope, causing the loose teeth to fall off. Anesthesiologists often cause medical disputes and corresponding claims, ranging from a few thousand to tens of thousands. Currently, few laryngoscope blades are equipped with tooth protection mechanisms. Therefore, how to protect the teeth when the laryngoscope blade is lifted is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0003] The object of the present invention is to provide a laryngoscope blade with tooth protection to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laryngoscope blade with tooth protection, including a blade body, which adopts a commonly used arc-shaped laryngoscope blade, which is arc-shaped as a whole, square in cross section, and has an arc-shaped plate-shaped end insertion end, which are all prior arts. The upper end of the blade body extends upward to form an extension part, and the circumference of the blade body is provided with a supporting mechanism that can elastically press against the inner side of the oral cavity after inflation to reduce the force on the teeth. The extension part is provided with an inflation mechanism that can inflate the supporting mechanism after pinching, and the inflation mechanism is located on one side of the extension part so that it can be pinched when the extension part is lifted. The inflation mechanism utilizes the pinching pressure and lifting force when pinching the extension part, because to lift the blade body, the extension part needs to be pinched and lifted. Here, one side of the force application point is the extension part, and the other side is the inflation mechanism, which utilizes the pinching pressure and lifting force. The greater the lifting and pinching force, the more inflation.

[0005] Preferably, the support mechanism includes a right airbag located at the right end of the sheet and a left airbag located at the left end of the sheet, and the right airbag and the left airbag are connected by a conduit, which can be flat and located outside the sheet. After being inflated, it rests against the inner side of the teeth, such as the upper and lower jaws, so that the force on the teeth can be reduced, the teeth can be prevented from being damaged, and protection can be achieved.

[0006] Preferably, the right airbag and the left airbag are both in an upwardly curved arc shape, so that they can better bypass the teeth and reduce the contact area with the teeth.

[0007] Preferably, the right airbag and the left airbag both extend upward along the sheet to form a flat protective portion for protecting the teeth. The protective portion is relatively soft and will form a wrapping even if it contacts the teeth, with a large area and low local pressure.

[0008] Preferably, the inflation mechanism includes an inflatable bag in the shape of an inverted right triangle at the right end of the extension portion, and the inflatable bag is connected to the protective portion on the right side, the end fixed to the extension portion is a vertical edge, the upper end is horizontal, or the upper end is bent in an arc to the lower right, and the right end is a hypotenuse.

[0009] Preferably, the upper side of the right end of the inflatable bag is bent in an arc to the lower right to facilitate lifting and pinching and pressing to apply force, so that it will not slide when pinching and lifting, making it convenient to apply force.

[0010] Preferably, a pressure plate is provided on the right wall of the inner cavity of the inflatable bag, and the bottom of the pressure plate is connected to the extension part by flipping, and the pressure plate and the extension part are connected by a torsion spring. The pressure plate is locally stressed, but can drive the right wall of the inflatable bag to move and compress as a whole, so that the inflation efficiency is high, the stability is good, and it is not easy to shake back and forth. Therefore, the pressure plate not only increases the inflation efficiency, but also is not easy to shake back and forth. The torsion spring can make the pressure plate rotate clockwise to evacuate and contract the right and left airbags.

[0011] Preferably, it also includes a retracting mechanism disposed between the pressure plate and the right airbag, which increases the contraction effect of the right airbag and reduces the height after being retracted, so as to facilitate placement into the oral cavity.

[0012] Preferably, the retracting mechanism includes a pull rope connected to the pressure plate, and the other end of the pull rope passes through the protective part and is fixed to the right wall of the inner cavity of the right airbag. The right end of the extension part is fixed with a positioning ring for the pull rope to pass upward, and the pull rope passes through the positioning ring upward and is bent to the right and fixed to the pressure plate. The positioning ring is used to increase the pulling efficiency of the pull rope. If there is no positioning ring, the pulling distance of the pull rope is very small when the pressure plate is turned over. With the positioning ring, the effect will be greatly increased.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When lifting the sheet, one side pinches the left end of the extension part, and the other side pinches the inflatable bag. The inflatable bag is compressed, and the right bag is inflated. The right bag inflates the left bag through the catheter, and presses against the upper and lower jaws of the inner cavity, thereby reducing the force on the teeth. At the same time, the protective part has toughness, and even if it contacts the teeth, it is relatively soft, so as to avoid the teeth from falling off due to hard contact. Here, the pinching force and the force generated when lifting are used, which not only realizes the lifting of the sheet, but also realizes inflation, killing two birds with one stone. In addition, the greater the lifting force, the more inflation, the greater the support strength of the left and right bags, and the protection of the teeth will also increase;

[0015] 2. The pull rope can compress the right airbag smaller as the pressure plate flips, making it easier to put it into the mouth. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 The present invention provides a technical solution for a laryngoscope blade with teeth protection: a laryngoscope blade with teeth protection, comprising a blade body 1, which adopts a commonly used arc-shaped laryngoscope blade, which is arc-shaped as a whole, square in cross section, and has an arc-shaped plate-shaped end insertion end, which are all prior arts. The upper end of the blade body 1 extends upward to form an extension part 2, and the circumference of the blade body 1 is provided with a supporting mechanism that can elastically press against the inner side of the oral cavity after inflation to reduce the force on the teeth. The extension part 2 is provided with an inflation mechanism that can inflate the supporting mechanism after pinching, and the inflation mechanism is located on one side of the extension part 2 so that it can be pinched when the extension part 2 is lifted. The inflation mechanism utilizes the pinching pressure and lifting force when pinching the extension part 2, because to lift the blade body 1, the extension part 2 needs to be pinched and lifted. Here, one side of the force application point is the extension part 2, and the other side is the inflation mechanism, which utilizes the pinching pressure and lifting force. The greater the lifting and pinching force, the more inflation.

[0023] The supporting mechanism includes a right airbag 3 located at the right end of the sheet 1 and a left airbag 4 located at the left end of the sheet 1, and the right airbag 3 and the left airbag 4 are connected by a conduit 5, which can be flat and located on the outside of the sheet 1. After inflation, it rests against the inside of the teeth, such as the upper jaw area and the lower jaw, which can reduce the force on the teeth, avoid damage to the teeth, and achieve protection. The right airbag 3 and the left airbag 4 are both in an arc shape that bends upward, so that they can better bypass the teeth and reduce the contact area with the teeth. The right airbag 3 and the left airbag 4 both extend upward along the sheet 1 to form a flat protective portion 6 for protecting the teeth. The protective portion 6 is relatively soft, and even if it contacts the teeth, it will form a wrapping with a large area and low local pressure.

[0024] The inflation mechanism includes an inflatable bag 7 in the shape of an inverted right triangle arranged at the right end of the extension part 2, and the inflatable bag 7 is connected to the protective part 6 on the right side, and the end fixed to the extension part 2 is a vertical side, the upper end is horizontal, or the upper end is bent in an arc to the lower right, and the right end is a hypotenuse. The upper side of the right end of the inflatable bag 7 is bent in an arc to the lower right to facilitate lifting and pinching and pressing to apply force, so that it will not slide when pinching and lifting, and it is convenient to apply force.

[0025] A pressure plate 8 is provided on the right wall of the inner cavity of the airbag 7, and the bottom of the pressure plate 8 is connected to the extension part 2 in a flip manner. The pressure plate 8 is connected to the extension part 2 by a torsion spring 9. The function of the pressure plate 8 is to bear force locally, but it can drive the right wall of the airbag 7 to move and compress as a whole. In this way, the inflation efficiency is high, and the stability is good, and it is not easy to shake back and forth. Therefore, the pressure plate 8 not only increases the inflation efficiency, but also is not easy to shake back and forth. The torsion spring 9 can make the pressure plate 8 rotate clockwise to evacuate and shrink the right airbag 3 and the left airbag 4. It also includes a retracting mechanism arranged between the pressure plate 8 and the right airbag 3. The retracting mechanism increases the contraction effect of the right airbag 3 and reduces the height after storage, which is convenient for placing in the oral cavity.

[0026] It also includes a retracting mechanism disposed between the pressure plate 8 and the right airbag 3. The retracting mechanism increases the contraction effect of the right airbag 3, reduces the height after storage, and is convenient for placement into the oral cavity. The retracting mechanism includes a pull rope 10 connected to the pressure plate 8, and the other end of the pull rope 10 is fixed on the right wall of the inner cavity of the right airbag 3 after passing through the protective portion 6, and a positioning ring 11 for the pull rope 10 to pass upward is fixed to the right end of the extension portion 2, and the pull rope 10 passes through the positioning ring 11 upward and then bends to the right and is fixed on the pressure plate 8. The function of the positioning ring 11 is to increase the pulling efficiency of the pull rope 10. If there is no positioning ring 11, when the pressure plate 8 is flipped, the pulling distance of the pull rope 10 is very small. With the positioning ring 11, the effect will be greatly increased.

[0027] In addition, the right airbag 3, the left airbag 4 and the inflatable bag 7 can all be made of transparent materials.

[0028] Working principle: when lifting the sheet body 1, one side pinches the left end of the extension part 2, and the other side pinches the inflatable bag 7. The inflatable bag 7 is compressed, and the right airbag 3 is inflated. The right airbag 3 inflates the left airbag 4 through the catheter 5, and presses against the upper and lower jaws of the inner cavity, thereby reducing the force on the teeth. At the same time, the protective part 6 has toughness, and even if it contacts the teeth, it is relatively soft to avoid the teeth from falling off due to hard contact. Here, the pinching force and the force generated when lifting are utilized, which not only realizes the lifting of the sheet body 1, but also realizes inflation, killing two birds with one stone. In addition, the greater the lifting force and the more inflation, the greater the support force of the left airbag 4 and the right airbag 3, and the protection of the teeth will also increase. The pull rope 10 can compress the right airbag 3 smaller as the pressure plate 8 flips, so that it is easy to put it into the oral cavity.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
