Utility model registration No. 3070527

The endotracheal tube protective material made of this synthetic resin is used by inserting its distal end into the mouth and biting the inserted portion with upper and lower teeth. The upper and lower teeth are fixed by biting them, but there is no structure for suppressing the movement of the tongue. For this reason, there existed a possibility that the movement of the intratracheal tube in the mouth inserted along the arcuate groove on the side surface of the endotracheal tube protective material could be mistakenly blocked by the tongue.
Further, the endotracheal tube is merely inserted along arcuate grooves formed on the left and right side surfaces of the endotracheal tube protector, and is not fixed. In the mouth, the endotracheal tube will not be displaced by following the arcuate groove on the side of the protective material, but the endotracheal tube is not fixed, so it may be displaced outside just before the mouth is inserted. The endotracheal tube in the mouth is also affected, and there is a possibility that the insertion cannot be performed smoothly.

  The present invention has been made in view of the above problems, and has been devised to solve the problems. The object of the present invention is to provide a tongue restraining piece formed at the lower end of the tip of a cylindrical member inserted into the mouth. Prevents the movement of the tongue in the mouth, prevents the tongue from obstructing the movement of the endotracheal tube and suction catheter in the mouth, and prevents the endotracheal tube from easily shifting outside just before the mouth is inserted. An object of the present invention is to provide an endotracheal tube protector capable of preventing the occurrence of trouble.

  In order to achieve the above-described problems, the invention of claim 1 is configured such that the endotracheal tube extends along the axial direction on both side surfaces of the cylindrical member having a through-hole formed in the axial direction. Each guide groove is formed, and a plurality of linear small protrusions that are laterally wide in the left-right width direction, which become slip resistance when gripped, are juxtaposed on the upper and lower surfaces of the cylindrical member in the axial direction, respectively. A stopper projection piece located outside the mouth at the normal position when the member is inserted into the distal end side mouth is formed around the circumference of the cylindrical member, and outside the mouth on both the left and right sides of the stopper projection piece on the same side as the guide groove. Each of which is formed with an engagement dovetail for engaging a portion of the endotracheal tube located at the end, and a tongue restraining piece that gently bends forward and obliquely downward at the lower end of the cylindrical member inserted into the mouth. Is.

  As a preferred embodiment of the invention of claim 1, two stopper projection pieces are formed at intervals in the front and rear, and the cylindrical member, the stopper projection piece and the tongue suppressing piece are made of synthetic resin.

According to the endotracheal tube protector according to the present invention comprising means for solving the problem, the tongue restraining piece that gently bends obliquely downward is formed at the lower end of the tip of the cylindrical member inserted into the mouth. The movement of the tongue in the mouth can be suppressed by the tongue suppressing piece, and the movement of the endotracheal tube and the suction catheter in the mouth can be prevented from being obstructed by the tongue.
In addition, by forming engagement dovetail grooves on the left and right sides of the stopper projection piece, by engaging a part of the endotracheal tube located outside the mouth with this engagement dovetail groove, the tube outside the mouth is It can be fixed and prevents the endotracheal tube from slipping outside just before the insertion of the mouth, and shifting outside makes it difficult for the endotracheal tube to be inserted into the body. It is possible to prevent troubles such as the tube from being pulled out, and to provide a very new and beneficial effect.

  Further, as in claim 2, when two stopper protrusions are formed at a distance from each other in the front-rear direction, the endotracheal tube is fixed at two places as compared with the case where one is provided. Does not tilt or shift easily. For this reason, it is easy to wrap the adhesive tape so that the endotracheal tube inserted into the body does not move and fix it to the tubular member of the endotracheal tube protector. Use the adhesive tape to attach the endotracheal tube to the tubular member. Can be fixed easily.

  Further, when the tubular member, the stopper projection piece and the tongue suppressing piece are made of synthetic resin as in claim 3, the endotracheal tube protector for holding the endotracheal tube is easily deformed like rubber. Even if a person bites unconsciously strongly, no debris will come out.

  Hereinafter, the present invention will be described more specifically based on embodiments for carrying out the invention described in the drawings.

  The endotracheal tube protector 1 according to the present invention is an instrument that protects an endotracheal tube a that is generally used by being inserted into the body from the mouth under circumstances unconscious by the user. To prevent the movement of the endotracheal tube a and the suction catheter b in the mouth from being obstructed by the tongue c, and to prevent the endotracheal tube a from easily shifting outside just before the mouth is inserted. It has a feature that can prevent the occurrence.

  In the figure, an endotracheal tube protector 1 having the above-described features includes a cylindrical member 2 in which a through-hole 21 is formed, guide grooves 3 formed on both side surfaces of the cylindrical member 2, and the cylindrical member 2. Horizontal linear protrusions 4 arranged in parallel on both upper and lower surfaces, stopper protrusions 5 formed around the circumference of the cylindrical member 2, engagement dovetail grooves 6 formed on the left and right sides of the stopper protrusions 5, and It is mainly composed of a tongue restraining piece 7 formed at the lower end of the cylindrical member 2 and the like.

  The cylindrical member 2 is a portion constituting the main body portion of the endotracheal tube protector 1, and the outer shape thereof has, for example, a substantially quadrangular shape in the outer cross section. Each corner of the substantially quadrangular cross section is formed in a rounded shape so that the mouth is not damaged. The cylindrical member 2 is made of, for example, a synthetic resin that is not broken even if it is strongly bitten by teeth.

  The cylindrical member 2 has a through-hole 21 formed in the central portion of the cross section in the axial direction that is the length direction of the cylindrical member 2. One end of the through hole 21 is formed on the front end side to be inserted into the mouth of the cylindrical member 2, and the other end of the through hole 21 is formed on the rear end side that is outside the mouth of the cylindrical member 2. The through hole 21 is used as a hole for inserting the suction catheter b. In the drawing, the through-hole 21 is a circular hole, but is not limited to this circular hole, and may be any shape as long as the suction catheter b can be inserted.

  The guide groove 3 is used as a guide path when the endotracheal tube a is guided along the inside of the mouth from the outside of the mouth, and the length direction, that is, the axis of the tubular member 2 is formed on both side surfaces of the tubular member 2. It is formed toward the core direction. The guide groove 3 is formed in, for example, a concave arc-shaped cross section on the left and right side surfaces having a substantially quadrangular shape on the outer peripheral cross section of the cylindrical member 2. For example, a concave arc-shaped cross section is formed as a concave arc-shaped cross section.

  That is, the left and right guide grooves 3 are formed, for example, in a cross-sectional shape that is recessed in a concave arc shape toward the central through hole 21, and the endotracheal tube a is attached along the recessed arc-shaped recess to It is designed to be inserted into the mouth from the outside. For this reason, the endotracheal tube a is prevented from shaking up and down at the side surface portion of the cylindrical member 2 by being along the guide groove 3 and prevented from being displaced in the mouth.

  The linear small protrusion 4 serves as a slip resistance when the tubular member 2 is gripped by hand, and serves to prevent the tubular member 2 from sliding back and forth due to sweat or the like in the palm. In the trachea in which the mouth is attached along the cylindrical member 2 or the cylindrical member 2 by preventing the distal end side of the cylindrical member 2 inserted by firmly grasping with the hand from moving back and forth in the mouth This prevents the tube a and the suction catheter b from being damaged and the endotracheal tube a and the suction catheter b inserted into the body from being displaced.

  The linear small protrusions 4 are provided on the upper surface side of the substantially rectangular outer cross section of the tubular member 2 so that the tubular member 2 has a slip resistance so that the tubular member 2 does not move in the front-rear direction when the tubular member 2 is gripped by hand. In addition, a plurality of them are arranged side by side in the front-rear direction toward the axial direction of the cylindrical member 2 on the lower surface side. A plurality of the linear small protrusions 4 are formed at a predetermined interval in the front-rear direction with respect to the axial direction of the cylindrical member 2. In the drawing, for example, 5 pieces are formed on each of the upper and lower surfaces.

  Each linear small protrusion 4 protrudes from the upper surface and the lower surface of the cylindrical member 2, and when the cylindrical member 2 is gripped by hand, the protruding portion becomes a slip resistance. That is, the fingers enter the space between the front and rear linear small protrusions 4 by gripping the cylindrical member 2 with the finger directed in the width direction between the linear small protrusions 4 formed in the width direction. Can be prevented from shifting in the front-rear direction. Each linear small protrusion 4 is formed toward the left-right width direction on the upper surface side and the lower surface side of the substantially square outer peripheral cross section of the cylindrical member 2, that is, is horizontally long. Each linear small protrusion 4 has, for example, a bowl shape, and the direction of the bowl shape is lateral, that is, the left-right width direction of the tubular member 2.

  The stopper projection piece 5 serves to prevent accidental swallowing of the tubular member 2 inserted into the mouth, and the cylinder at a position located outside the mouth at the normal position when the tubular member 2 is inserted into the distal end side mouth. It is formed in the circumferential direction of the shaped member 2. When the stopper protruding piece 5 hits the periphery of the mouth, the tubular member 2 can be prevented from being swallowed by mistake.

  The stopper protrusion 5 is formed to protrude upward and downward from, for example, the upper surface and the lower surface of the substantially square outer peripheral cross section of the cylindrical member 2. The stopper projection piece 5 is made of, for example, a synthetic resin, is integrally formed with the cylindrical member 2, and is integrated.

  The stopper protrusions 5 are formed at two positions in the front and rear with a slight gap in the length direction of the cylindrical member 2, that is, the axial direction. Among these, the front stopper projection piece 51 that is closer to the distal end side of the cylindrical member 2 is formed on the rear side of the linear small projection 4. The front stopper projection piece 51 has an upper half side and a lower half side formed in a substantially arc shape or a substantially fan shape, respectively. Engagement dovetail grooves 6 are formed on both the left and right sides, which are the boundary between the upper half side and the lower half side, and are divided vertically with the engagement dovetail groove 6 interposed therebetween.

  The rear stopper projection piece 52 that is closer to the rear end side of the tubular member 2 is formed on the rear side of the front stopper projection piece 51 with a slight gap therebetween. During this period, the endotracheal tube a engaged between the engagement dovetails 6 before and after the front and rear stopper projections 51 and 52 is simply fixed to the cylindrical member 2 using an adhesive tape. In this case, the space is slightly wider than the space around which the adhesive tape is wound, that is, the width of the adhesive tape.

  The rear stopper protrusion 52 has an upper half side and a lower half side formed in a substantially arc shape or a substantially fan shape, respectively. Engagement dovetail grooves 6 are formed on both the left and right sides, which are the boundary between the upper half side and the lower half side, and are divided vertically with the engagement dovetail groove 6 interposed therebetween. Further, the upper half side and the lower half side are divided into left and right by a vertical groove 52a formed in the middle in the vertical direction. Further, the upper and lower vertical grooves 52 a communicate with the lateral grooves 52 b formed on the sides of the upper and lower surfaces of the cylindrical member 2 in the width direction of the cylindrical member 2.

  In the cylindrical member 2 where the rear stopper projection piece 52 is formed, the area of the connecting portion with the rear stopper projection piece 52 is reduced by the vertical groove 52a and the horizontal groove 52b. Thereby, the cylindrical member 2 has a structure that is less susceptible to deformation prevention by the rear stopper projection piece 52 at the location where the rear stopper projection piece 52 is formed than at the location where the front stopper projection piece 51 is formed.

  The engagement dovetail groove 6 is a part of the endotracheal tube a that is attached along the guide groove 3 formed on the left and right side surfaces of the cylindrical member 2, and the front stopper that is on the same side as the guide groove 3. The left and right sides of the protrusion 51 and the rear stopper protrusion 52 are engaged with positions outside the mouth so as not to move.

  The engagement dovetail grooves 6 are respectively formed on the left and right sides of the front stopper projection piece 51 and the rear stopper projection piece 52 on the same side as the guide groove 3. The left and right engaging dovetail grooves 6 are provided in the middle of the guide grooves 3 formed on the left and right side surfaces of the cylindrical member 2. The back end surfaces of the left and right engaging dovetail grooves 6 and the back end surfaces of the left and right guide grooves 3 are substantially flush with each other.

  The left and right engagement dovetail grooves 6 are opened outward. That is, the groove opening 61 of the right engagement dovetail groove 6 is formed and opened in the right side surface portion, and the groove opening 61 of the left engagement dovetail groove 6 is formed and opened in the left side surface portion. . Each groove opening 61 is open between the upper and lower sides, and the opening width between the upper and lower sides is a dovetail narrower than the inner groove width, and the endotracheal tube a engaged in the groove is easily connected to this groove. It does not come off the ant groove 6.

  The inner side having an inner groove width wider than the opening width of the right and left engaging dovetail grooves 6 is formed in, for example, a substantially arc shape around the top and bottom, and a small protrusion 62 for preventing slippage is formed on the inner peripheral side surface of the inner periphery. A plurality are formed around. Each of the small protrusions 62 is formed in an arc shape, and these small protrusions 62 press a part of the surface of the endotracheal tube a engaged in the engagement dovetail groove 6, so that the endotracheal tube a Is not easily removed from the engagement dovetail groove 6.

  The tongue suppression piece 7 prevents the movement of the tongue c in the mouth and prevents the movement of the endotracheal tube a and the suction catheter b in the mouth by the tongue c, and the tip of the cylindrical member 2 inserted into the mouth The lower part is formed in a shape that bends gently forward and diagonally downward. The tongue suppressing piece 7 is made of, for example, a synthetic resin, and is integrally formed at the lower end of the cylindrical member 2 so as to be integrated.

  The tongue suppressing piece 7 is formed in a state bent downward while drawing a gentle arc while projecting forward from the lower end of the tip of the cylindrical member 2. The upper and lower ends and both left and right ends of the distal end side of the tongue suppressing piece 7 are formed in a rounded shape so that the mouth is not damaged. Similarly, the upper end side of the cylindrical member 2 formed so that the tongue suppressing piece 7 projects forward is formed so as to incline toward the rear side. The upper end of the tip does not hit the upper inner surface of the mouth and be damaged.

  When the distal end side of the cylindrical member 2 is inserted into the mouth, the tongue suppressing piece 7 is in a state in which the lower surface of the tongue suppressing piece 7 that gently bends downward is in contact with the upper side of the tongue c and pressed from above. Is prevented from moving freely in the mouth to prevent the tongue c from obstructing the movement of the endotracheal tube a and the suction catheter b in the mouth. For this reason, the shape which bends gently in the downward direction of the tongue suppression piece 7 resembles the shape of the surface side of the tongue c when viewed from the side.

  Next, the use of the endotracheal tube protector based on the configuration of the embodiment for carrying out the invention will be described below.

  First, the endotracheal tube a is inserted from the mouth and inserted into the body through the throat. After the endotracheal tube a has been inserted into a predetermined location, in order to protect the endotracheal tube a so that it does not move or accidentally bite with teeth, Insert the tube protector 1 in the tube.

  The distal end side of the tubular member 2 of the endotracheal tube protector 1 is inserted into the mouth. At this time, the distal end side of the tubular member 2 is inserted while the endotracheal tube a already inserted in the mouth is caused to follow the left or right guide groove 3 of the tubular member 2. The lower surface of the tongue restraining piece 7 that gently bends downward comes into contact with the upper side of the tongue c.

  When the distal end side of the tubular member 2 of the endotracheal tube protector 1 is inserted into the mouth, the lower surface of the tongue restraining piece 7 that gently bends downward comes into contact with the upper side of the tongue c and is pressed from above. The tongue restraining piece 7 restrains c from moving freely in the mouth. Since the free movement of the tongue c is suppressed, the moving tongue c does not move the endotracheal tube a and the suction catheter b by mistake.

  After the distal end side of the cylindrical member 2 is inserted into a just right position in the mouth, the user bites the upper and lower surfaces of the cylindrical member 2 with upper and lower teeth so that the user does not move. Further, the linear small protrusion 4 of the cylindrical member 2 protruding outside the mouth of the cylindrical member 2 with one hand is grasped with one hand so as not to move back and forth. A part of the endotracheal tube a protruding outward from the mouth is pushed into each of the front and rear stopper projection pieces 51 and 52 from the respective groove openings 61 of the front and rear engaging dovetail grooves 6. Engage with.

  After engaging a part of the endotracheal tube a with the front and rear engaging dovetail grooves 6, do not move into the mouth with teeth and one hand so that the endotracheal tube a inserted in the body does not move back and forth. It fixes to the side of the cylindrical member 2 currently fixed to the side using an adhesive tape. By pressing the outer side surface of the endotracheal tube a located in the portion between the front and rear engaging dovetail grooves 6 formed on the side surfaces of the front and rear stopper projection pieces 51 and 52 with an adhesive tape, An adhesive tape is wound many times around the side peripheral surface between the dovetail grooves 6, and the endotracheal tube a attached along the guide groove 3 of the tubular member 2 is fixed to the tubular member 2.

  As a result, the endotracheal tube a is integrated with the tubular member 2, and the endotracheal tube a inserted into the body does not escape from the body unless the tubular member 2 is moved in the mouth. The tube protector 1 is protected in a stable state.

  Further, in the event of an emergency, when the suction catheter b needs to be inserted into the body and the foreign matter in the body needs to be sucked, the suction catheter b is inserted into the body using the through hole 21 formed in the center of the cylindrical member 2. Insert into. The insertion is performed by inserting the distal end of the suction catheter b into the through-hole 21 and gradually pushing the suction catheter b through the throat into the body.

  Note that the present invention is not limited to the embodiment for carrying out the invention described above, and various modifications can be made without departing from the spirit of the invention.
