Description

  The present invention relates to an intubation support tool, an intubation support device, and an intubation support system.

  For example, there is a case where artificial respiration has to be performed as a primary lifesaving treatment for a patient presenting with consciousness disorder due to an accident or the like. This artificial respiration may be performed without using a device, but may be performed using a ventilator.

  When performing artificial respiration using a ventilator, an intubation tube whose proximal end is connected to the ventilator is inserted into the patient's trachea, and air is sent from the ventilator to the trachea via the intubation tube.

  By the way, when a patient loses consciousness, the muscles of the pharynx and larynx are relaxed and the lower jaw is depressed due to gravity, resulting in tongue root depression, thereby blocking the airway.

  Therefore, when inserting the intubation tube into the trachea (target site) as described above (hereinafter referred to as “intubation work”), first, the tongue is pushed up to open the obstructed airway to secure the airway. I need it.

  An intubation support device used for securing this airway is known (see, for example, Patent Document 1).

  An intubation support apparatus described in Patent Literature 1 is for observing a pharynx or larynx, which is configured to be detachable from an apparatus main body, an intubation support tool detachably attached to the apparatus main body, and the intubation support tool. And have a scope.

  The intubation support tool is a long member that is curved in the middle.For example, the intubation support tool is inserted from the mouth of a patient with impaired consciousness, and a predetermined portion on the distal end side comes into contact with the tongue base portion of the patient, thereby removing the tongue base portion. It is configured to secure the airway by lifting it up. Further, the intubation support tool has a groove into which the intubation tube can be inserted along the longitudinal direction of the intubation support tool.

However, in the intubation support apparatus described in Patent Document 1, for example, after the use of the intubation support apparatus, the intubation support tool may be removed and washed. In this case, the intubation support tool is large, its shape is complicated, etc. For this reason, there is a possibility that the cleaning becomes insufficient. Moreover, in the intubation assistance apparatus of this patent document 1, since insertion / extraction of an intubation tube is repeated with respect to a groove | channel, the said groove | channel becomes a part especially worn. An intubation aid with worn grooves is incompatible with the intubation operation even if other parts than the groove are normal (no damage or the like), and must be discarded.
Moreover, in the intubation assistance apparatus, it is conceivable that the member in which the groove is formed is configured as a separate body, and the separate body is configured to be detachable. In this case, only the separate body can be cleaned, but a positional shift may occur in the separate body during use of the intubation support device.

  As shown in FIG. 11, a CCD (imaging device) 53 and a white LED (light emitting diode) 55 as a light source are installed inside the distal end portion of the main body 51. Further, one or more imaging lenses (lens groups) having an objective lens 54 are installed on the distal end side of the CCD 53 of the main body 51, and an illumination lens 56 is installed on the distal end side of the white LED 55. Yes. In the following, one or more imaging lenses (lens group) having the objective lens 54 are simply referred to as “objective lens 54”.

  Specifically, two holes (not shown) that are open (open) at the tip are formed at the tip of the main body 51. The CCD 53 and the objective lens 54 are installed in one hole, and the tip of the hole is sealed in a liquid-tight manner by a window part 57 having optical transparency. The white LED 55 and the illumination lens 56 are installed in the other hole, and the tip of the hole is sealed in a liquid-tight manner by a window part 58 having light permeability. The illumination lens 56 may be omitted, and the window portion 58 may also serve as the illumination lens. The CCD 53 and the objective lens 54, the white LED 55 and the illumination lens 56 are installed in different holes, and the separate windows 57 and 58 are provided, so that the CCD 53 and the objective lens 54, the white LED 55 and the illumination lens 56 are provided. Further, it is possible to prevent a possibility that some components of the light emitted from the white LED 55 are shielded from each other and become stray light and adversely affect the CCD 53. The main body 51 fixes the positional relationship between the CCD 53 and the objective lens 54, the positional relationship between the white LED 55 and the illumination lens 56, and the positional relationship between the CCD 53 and the objective lens 54, the white LED 55 and the illumination lens 56, respectively. It has a function.

  The control lines and signal lines of the CCD 53 and the signal lines of the white LED 55 pass through the inside of the main body 51 and are connected to predetermined terminals of the connector 52. The CCD 53 and the objective lens 54 constitute image light acquisition means, and the white LED 55 and the illumination lens 56 (window portion 58) constitute illumination means.

  In this scope 5, reflected light (image light) from an observation site, which is a site where the distal end wall 41 of the support tool main body 4 is located or a site in the vicinity thereof, is placed on the light receiving surface (imaging surface) of the CCD 53 by the objective lens 54. The image is formed and the subject image (image light) is picked up by the CCD 53. That is, the observation region is imaged by the CCD 53. Specifically, for example, the CCD 53 picks up (acquires) at least the subject's epiglottis and its vicinity when the patient's epiglottis is lifted by a tongue piece 42 (to be described later) of the support tool body 4, and the support tool body When the airway is secured by 4, at least a subject image of the glottal fissure of the patient and its vicinity (larynx or glottic fissure) can be captured.

  When the white LED 55 emits light, the light emitted from the white LED 55 is applied to the observation site from the distal end wall 41 of the support tool main body 4 via the illumination lens 56, and the observation site is illuminated. Thereby, the observation site can be illuminated with sufficient brightness.

  The number of white LEDs 55 is one in the illustrated example, but is not limited thereto, and may be two or more depending on the F number of the objective lens 54 and the sensitivity characteristics of the CCD 53.

  The configuration of the image light acquisition unit is not limited to the above. The image light acquisition means may be constituted by, for example, an image guide and a CCD (imaging device) provided on the base end side of the image guide. The image guide includes, for example, a fiber bundle and an objective lens provided on the tip side of the fiber bundle. The fiber bundle is formed by bundling a plurality of optical fibers made of, for example, quartz, multicomponent glass, plastic, or the like. In the image light acquisition means having this configuration, the image guide captures the reflected light (image light) from the observation site with the objective lens, and transmits the captured image light (subject image) to the CCD via the fiber bundle. Captures the subject image. In this configuration example, the image guide constitutes means for guiding the image light (subject image) of the observation site to the image sensor. Note that the imaging element may be provided in the apparatus main body 2 or may be provided in the intubation support tool 3. Moreover, it is good also as a structure which observes an observation site | part with the naked eye by providing an eyepiece instead of CCD.

For example, the illumination unit may include a light guide and a white LED (light source) provided on the base end side of the light guide. The light guide includes, for example, a fiber bundle and an illumination lens provided on the distal end side of the fiber bundle. The fiber bundle may be made of the same material as the fiber bundle of the image guide. In the illuminating means having this configuration, the light guide guides light emitted from the white LED, and irradiates the observation site from the distal end wall 41 of the support tool body 4 to illuminate. In this configuration example, the light guide constitutes means (light guiding means) for guiding light from the light source to the distal end wall 41 of the support tool body 4. The light source may be provided in the apparatus main body 2 or may be provided in the intubation support tool 3.

  An intubation support tool 3 is attached to the apparatus main body 2. The intubation support tool 3 is installed in the support tool body 4 having the same function as that of a general oral airway, a guide member 8 that is detachably attached to the support tool body 4, and the support tool body 4. And a lock mechanism 9 for detachably attaching the guide member 8 to the support tool body 4. The intubation support tool 3 is used in a state in which the guide member 8 is attached to the side portion of the support tool body 4 via the lock mechanism 9. Hereinafter, this state is referred to as a “guide member mounting state”.

  The support device body 4 is composed of a long (long shape) member, and is inserted from the patient's mouth (oral cavity) into the trachea, which is the target site of the patient, or the vicinity thereof while being attached to the apparatus body 2. The For example, the support device main body 4 is used by being inserted from the mouth of a patient with impaired consciousness or a general anesthesia patient, and a tongue piece (protrusion) 42 described later on the distal end side of the support device main body 4 is used to cover the patient's epiglottis. The patient's airway is secured by bringing a predetermined portion on the distal end side of the support tool body 4 into contact with the tongue base portion of the patient while lifting.

  As shown in FIGS. 1 and 2, the support tool main body 4 has a curved portion 40 that is curved in the middle of the longitudinal direction so that the distal end side faces the lateral direction in FIG. 1. The angle formed with the side is approximately 90 °. Further, in the present embodiment, the support tool body 4 (intubation support tool 3) may be entirely light-transmitting, or only necessary portions (parts) may be light-transmitting. May be.

  In addition, the distal end wall 41 of the support device main body 4 is provided with a plate-like tongue piece 42 that protrudes toward the distal end direction and has optical transparency. The tongue piece 42 is erected from an extension of the inner side surface 401 of the curved portion 40 of the tip wall 41. During the intubation work, the tongue piece 42 can lift the epiglottis of the patient, thereby ensuring the patient's airway easily and reliably. The tip wall 41 of the support tool body 4 is inclined with respect to the tongue piece 42.

  As shown in FIG. 8, the shape of the tongue piece 42 in a plan view is substantially rectangular. Moreover, each corner | angular part of the tongue piece 42 is roundish, and the safety | security at the time of insertion improves by this. Note that the shape of the tongue piece 42 in a plan view is not limited to a quadrangle, and examples thereof include a semi-elliptical shape and a semi-circular shape.

  As shown in FIGS. 1 and 2, the support tool main body 4 is formed with a side wall 48 integrally connected (formed) to the tip wall 41 and the tongue piece 42.

  As shown in FIG. 7, the support tool main body 4 (intubation support tool 3) has a substantially quadrangular outer shape in the cross section near the distal end wall 41 when the guide member is mounted. Moreover, as for the dimension in the cross section of the front end wall 41 of the support tool main body 4, the width w is preferably about 15 to 40 mm, more preferably about 25 to 30 mm, and the thickness t is about 10 to 30 mm. It is preferable that it is about 15 to 20 mm. With such a numerical range, the intubation support tool 3 can be easily and quickly inserted into the patient during the intubation work, and the burden on the patient can be reduced. Moreover, since the tongue piece 42 is plate-shaped, when the distal end wall 41 of the support tool main body 4 is brought into contact with (pressed against) the tongue base portion of the patient in intubation work, the patient's tongue comes to the distal end of the support tool main body 4. It is possible to prevent the wall 41 from drooping to the side, and therefore, it is possible to prevent the field of view of the CCD 53 from being narrowed by the tongue. The outer shape is not limited to a quadrangle, and other examples include an elliptical shape, a semi-elliptical shape, a circular shape, and a semicircular shape.

  As described above, in the support tool main body 4, as an installation part in which at least a part of the scope 5 (the whole in the present embodiment) is installed, the support tool main body 4 extends from the base end portion to the distal end wall 41, that is, the support tool main body. A scope guide hole 44 is formed along the longitudinal direction of 4. In this case, the distal end portion of the scope guide hole 44 (in this embodiment, the entire scope guide hole 44) is unevenly distributed in the width direction of the tongue piece 42.

Further, the scope guide hole 44 has a substantially circular cross section, and is opened (opened) at the base end portion of the support tool body 4. The base end side of the scope guide hole 44 is sealed in a liquid-tight (air-tight) manner with the intubation support tool 3 attached to the apparatus main body 2.
Further, the scope guide hole 44 has its distal end closed by the distal end wall 41.

  Here, as shown in FIG. 8, the distal end portion of the scope guide hole 44 is inclined toward the intubation tube 200 (guide member 8) inserted into the guide member 8. In other words, the scope guide hole 44 supports the center line 59 of the visual field of the CCD 53 (image light acquisition means) of the scope 5 accommodated in the scope guide hole 44 so as to face the intubation tube 200 (guide member 8) side. The tool body 4 is formed so as to be inclined with respect to the central axis 47 of the tip wall 41 of the tool body 4. Thereby, in the intubation work, when the intubation tube 200 is drawn out from the distal end wall 41 of the support tool main body 4, the intubation tube 200 advances toward the substantially central portion of the image displayed on the display 71. It is configured. Thereby, in the intubation work, the positional relationship between the glottic cleft that is the entrance of the trachea and the distal end portion of the intubation tube 200 can be grasped very easily by looking at the image displayed on the display 71.

  As shown in FIG. 8, a through hole 46 is formed in the support tool main body 4 from the base end portion to the distal end wall 41, that is, along the longitudinal direction of the support tool main body 4. In this case, the tip of the through hole 46 is located between the guide member 8 and the scope guide hole 44 and on the tongue piece 42 side. Further, the distal end of the through hole 46 opens in the distal end wall 41 of the support tool main body 4.

  Inside the through hole 46, for example, a suction tube or forceps (not shown) is provided. The suction tube and forceps may be provided in the through hole 46 so as to be freely inserted and removed, or may be fixed. With the suction tube, for example, fluid foreign substances such as saliva and sputum can be sucked and removed. The forceps can remove, for example, solid foreign matters.

  The number of through holes 46 is one in the illustrated example, but is not limited thereto, and may be two or more.

  As described above, the guide member 8 is detachably attached to the side of the support tool main body 4. The guide member 8 has a long shape similar to that of the support tool body 4 and has a curved portion 81 that is curved in the middle. In the guide member mounting state shown in FIG. 1, the bending state of the bending portion 81 of the guide member 8 and the bending state of the bending portion 40 of the support device main body 4 coincide.

  As shown in FIGS. 1, 2, and 4, the guide member 8 includes a plate-shaped main body portion 80, a guide portion (guide member side tube restricting portion) 82 into which the intubation tube 200 is inserted, and a lock mechanism 9. And a rib (projection) 84 that engages with the support tool main body 4.

  A guide portion 82 is provided on one surface of the main body portion 80, that is, on the surface opposite to the support tool main body 4 when the guide member is mounted. The guide part 82 is a part that guides the inserted intubation tube 200 to the target part of the patient in a state where the guide member is mounted when performing the intubation work.

  As shown in FIGS. 1, 3, 4, and 7, the guide portion 82 is a portion whose cross-sectional shape forms an arc shape (U shape). Thereby, a recess (groove) 821 along the longitudinal direction of the guide member 8 is formed inside the guide portion 82. Further, the recess 821 opens toward the inside of the bending portion 81. In the guide member 8, the intubation tube 200 can be inserted into the recess 821 (see FIGS. 1 and 3). In addition, the width (maximum width) of the recess 821 is set to be slightly larger than the outer diameter of the intubation tube 200. Thereby, insertion (intubation) of the intubation tube 200 to the recessed part 821 can be performed easily.

  Moreover, the general usage method of the intubation support apparatus 1 is that the user is first positioned on the upper side of the lying patient and the intubation support is made so that the display 71 in the state shown in FIG. 9 faces the user side. Hold the device 1. When the user, the patient, and the intubation assistance device 1 are in this positional relationship (positional relationship during use), the guide portion 82 (concave portion 821) is provided on the right side (right hand side) for the user of the support tool body 4. Will be.

  When the airway is secured by the support device main body 4, the guide portion 82 has a function of guiding the intubation tube 200 inserted from the patient's mouth to the patient's trachea as described above. Moreover, the intubation tube 200 inserted in the guide part 82 can also be easily removed in a state where the support tool main body 4 is inserted into the patient.

  When the airway is secured by the support tool main body 4, the intubation tube 200 is introduced (inserted) from the proximal end portion of the guide portion 82 into the guide portion 82 and is drawn out toward the distal end. At this time, the intubation tube 200 slides forward in the guide portion 82 while being guided by the inner peripheral surface 822 of the guide portion 82. Then, the distal end of the intubation tube 200 is fed out from the distal end of the guide portion 82 toward the glottic fissure behind the larynx. In this case, since the guide part 82 is provided on the right side for the user of the support tool main body 4, the user can operate the intubation tube 200 with the right hand, which is the same technique as the video laryngoscope.

  In addition, it is preferable that the inner peripheral surface 822 of the guide portion 82 is subjected to a process for reducing friction with the intubation tube 200 that occurs when the intubation tube 200 is inserted. Thereby, intubation work can be performed easily. Such a treatment method is not particularly limited, and examples thereof include performing fluorine processing and making the surface have a shape in which gentle irregularities are continuous.

  As shown in FIG. 1 and FIG. 7, in the guide member mounting state, the intubation tube 200 inserted into the guide portion 82 is detached from the opening side of the concave portion 821 of the guide portion 82. This is prevented by the portion (main body side tube restricting portion) 49. That is, in the guide member mounting state, the intubation tube 200 inserted into the guide portion 82 is restricted from moving in the radial direction between the guide portion 82 and the tube restricting portion 49 of the support tool main body 4. Thereby, it is possible to reliably prevent the intubation tube 200 from being unintentionally detached from the guide portion 82 during the intubation work and the intubation tube 200 from reaching the target site of the patient.

  The tube restricting portion 49 is configured by a rib (wall portion) protruding from the support tool body 4 on the extension in the width direction of the inner surface 401 of the bending portion 40 of the support tool body 4. Thereby, the guide part 82 can be covered from the opening side of the recessed part 821 in the state where the guide member is mounted, and thus the intubation tube 200 can be reliably prevented from being detached from the guide part 82.

  As shown in FIGS. 4 and 7, a rib 84 projects from the other surface of the main body 80, that is, the surface opposite to the surface where the guide portion 82 is disposed. The rib 84 is a portion that engages with the support tool main body 4 in a state where the guide member is mounted. The rib 84 includes a first rib 841 extending along the longitudinal direction of the main body portion 80 (guide member 8) and a second rib 842 extending along the width direction of the main body portion 80. (See FIG. 7).

  The first rib 841 is disposed at the edge of the main body 80. The first rib 841 is a portion whose cross-sectional shape forms an “L” shape. The second rib 842 is formed continuously (integrally) with the first rib 841 at the tip of the first rib 841. The second rib 842 is a portion whose cross-sectional shape forms a “T” shape.

  As shown in FIG. 2, a groove 43 into which the rib 84 is inserted is formed in the support tool main body 4 at a position corresponding to the rib 84 when the guide member is mounted. The groove 43 includes a first groove 431 into which the first rib 841 is inserted and a second groove 432 into which the second rib 842 is inserted.

  The cross-sectional shape of the first groove 431 is “L” like the first rib 841, and the first rib 841 can be inserted. Further, the second groove 432 has a “T” -shaped cross section similar to the second rib 842, and the second rib 842 can be inserted therein.

  As shown in FIG. 2, in the intubation support tool 3, when the guide member 8 is mounted on the support tool body 4, the first rib 841 of the guide member 8 is slid along the first groove 431 of the support tool body 4. The second rib 842 is inserted into the second groove 432 while being inserted (inserted). Thereby, the mounting direction of the guide member 8 is a direction from the distal end side to the proximal end side with respect to the support tool main body 4. Further, when the guide member 8 attached to the support tool main body 4 is detached, the direction of removal is opposite to the above.

  Thus, in the intubation assistance tool 3, the attachment / detachment direction (movement direction) of the guide member 8 with respect to the assistance tool main body 4 is regulated. Thereby, even if the support tool main body 4 is attached to the apparatus main body 2, the attaching / detaching operation of the guide member 8 can be performed from the side opposite to the side where the apparatus main body 2 is disposed. Thereby, it is prevented that the apparatus main body 2 becomes obstructive at the time of attachment / detachment operation, Therefore The attachment / detachment operation can be performed easily. Therefore, in the intubation support tool 3, it can be said that the rib 84 of the guide member 8 and the groove 43 of the support tool main body 4 function as the regulating means 32 that regulates the attaching / detaching direction of the guide member 8.

  As shown in FIGS. 2 and 4 to 6, a mounting portion 83 is provided at the base end portion of the main body portion 80. The mounting portion 83 is a part that is detachably mounted on the lock mechanism 9 of the guide member 8.

The mounting portion 83 is constituted by a defect portion 831 in which both edge portions of the main body portion 80 are partially missing. In the mounting portion 83, chamfered portions 832 that are chamfered are formed at the corners on both sides of the base end portion of the main body portion 80.
Note that the attachment / detachment state of the mounting portion 83 with respect to the lock mechanism 9 will be described later.

  In the guide member 8 having such a configuration, the main body portion 80, the guide portion 82, the mounting portion 83, and the rib 84 may be integrally formed. It may be connected.

In addition, the constituent material of the guide member 8 is not particularly limited, and examples thereof include various thermoplastic resins such as polyethylene and polypropylene, and various metal materials such as stainless steel.
The guide member 8 is attached to the support tool main body 4 via the lock mechanism 9.

  As shown in FIGS. 1 and 2, the lock mechanism 9 is disposed in the vicinity of the base end portion of the support tool main body 4. As shown in FIGS. 5 and 6, the lock mechanism 9 includes a pair of engaging members 91 that are arranged to face each other, and a coil spring (biasing portion) 92 that urges the pair of engaging members 91 in a direction approaching each other. And a lid body 93 that covers each engaging member 91 and the coil spring 92.

  Since the pair of engaging members 91 have the same configuration, the one engaging member 91 will be representatively described below.

  The engaging member 91 is configured by a member having a long plate shape. The engagement member 91 is a rotation support portion 913 that is supported on the support tool main body 4 so as to be rotatable. Thereby, the engagement member 91 can be rotated with the rotation support portion 913 as a fulcrum (center) (see FIGS. 5 and 6). The rotation support portion 913 is not particularly limited. For example, the rotation support portion 913 includes a bearing (through hole) that penetrates the engagement member 91 in the thickness direction, and is formed to protrude from the support tool body 4 to the bearing. It can be configured such that the shaft is fitted.

  The engaging member 91 has an engaging portion 911 provided at the distal end portion thereof and an operation portion 912 provided at the proximal end portion.

  The engaging portion 911 is formed so as to protrude toward the other engaging member 91 that faces the engaging portion 911. Since the engagement member 91 can be rotated via the rotation support portion 913, the engagement portion 911 can approach / separate from the engagement portion 911 of the other engagement member 91 that faces the engagement member 91. . Then, as shown in FIG. 5, the engaging portion 911 can engage with the missing portion 831 of the mounting portion 83 of the guide member 8 in the approached state. In addition, the engaging portion 911 is formed with an inclined portion 914 that is inclined with respect to the mounting direction (attachment / detachment direction) of the guide member 8 at the distal end portion thereof.

  In the lock mechanism 9, when the guide member 8 is mounted, the guide member 8 is moved toward the lock mechanism 9 from the mounting portion 83 side. At this time, each chamfered portion 832 of the mounting portion 83 of the guide member 8 slides on the inclined portion 914 of the engaging portion 911, and the engaging portion 911 faces outward against the urging force of the coil spring 92. And push. When each chamfered portion 832 passes through the engaging portion 911, the engaging portion 911 engages with the missing portion 831 of the mounting portion 83 of the guide member 8. As described above, in the intubation support tool 3, the mounting operation of the guide member 8 can be performed by a simple operation of simply inserting the guide member 8 into the support tool body 4, and the operability is excellent. The mounted guide member 8 is supported and fixed as a whole along the longitudinal direction by the operation of the lock mechanism 9 and the restriction means 32. Thereby, it can prevent reliably that position shift arises in the guide member 8 during operation of the intubation assistance apparatus 1. FIG.

  The operation portion 912 is formed so as to protrude in a direction opposite to the protruding direction of the engaging portion 911. As shown in FIG. 6, by pressing the operation portion 912 in the direction of the arrow in FIG. 6, the engaging portion 911 is separated from the missing portion 831 of the mounting portion 83 of the guide member 8. An operation of releasing the engagement with the guide member 8 can be performed.

  In addition, this release operation must be performed by pressing the operation portion 912 of each engagement member 91 in a lump. For this reason, even if one operation part 912 is accidentally pressed during use of the intubation support device 1 (in the procedure), as long as the other operation part 912 is not pressed, the lock mechanism 9 and the guide member 8 The engagement state is maintained, and the guide member 8 is prevented from being detached.

  Both ends 921 of the coil spring 92 are connected to portions on the tip side of the rotation support portions 913 of the respective engaging members 91. Accordingly, the engaging portions 911 of the engaging member 91 can be urged toward each other, and accordingly, when the engaging portions 911 are respectively engaged with the missing portions 831 of the mounting portion 83 of the guide member 8. The engagement state can be reliably prevented from being unintentionally released (see FIG. 5). Thereby, the guide member 8 can be reliably fixed to the support tool main body 4.

  Further, the engagement state is released by pressing the operation portion 912 of each engagement member 91 as described above against the urging force of the coil spring 92. Then, the guide member 8 can be detached (removed) from the lock mechanism 9 by pulling the guide member 8 in the proximal direction.

  As described above, the lock mechanism 9 is configured to satisfy both conflicting properties of reliable fixing of the guide member 8 and easy detachment of the guide member 8. Since the guide member 8 is attached / detached on the side opposite to the apparatus main body 2 via the lock mechanism 9, the attaching / detaching operation can be performed in a state where the support tool main body 4 is attached to the apparatus main body 2. Thereby, when exchanging the guide member 8 which will be described later, the exchanging work can be easily performed without the apparatus main body 2 being in the way.

  As shown in FIGS. 1 and 2, the lid 93 is formed of a plate member having a quadrangular shape in plan view. A plurality of spacers 931 protrude from the back surface of the lid 93. Thereby, the gap | interval 932 can be formed between the back surface of the cover body 93, and the support tool main body 4 (refer FIG. 1). Each engagement member 91 and coil spring 92 are disposed in the gap 932. Thereby, it is possible to reliably prevent a finger or the like from being inadvertently pinched between the engaging members 91 and the coil springs 92, and safety during operation of the lock mechanism 9 is ensured. In this embodiment, the lid 93 is fixed to the support tool body 4 via three bolts 94.

  In addition, it does not specifically limit as a constituent material of each engaging member 91, the coil spring 92, and the cover body 93, For example, various metal materials, such as stainless steel, can be mentioned.

  Now, as shown in FIG. 3, in the intubation support tool 3 (intubation support device 1), a plurality of types (three types in the present embodiment) of the guide member 8 having the above-described configuration are prepared. Each guide member 8 corresponds to the outer diameter of the intubation tube 200. That is, each guide member 8 has a different width and depth (shape and size) of the guide portion 82, and these sizes are suitable for the outer diameter of the intubation tube 200 to be inserted (returned). It has become a thing.

  Further, as described above, the intubation support tool 3 can hold the intubation tube 200 between the guide portion 82 of the guide member 8 and the tube restricting portion 49 of the support tool body 4 in a state where the guide member is mounted. Then, by appropriately selecting and using the three types of guide members 8, the separation distance h between the guide portion 82 of the selected guide member 8 and the tube restricting portion 49 of the support tool main body 4 changes. Thereby, it can respond to the outer diameter of the intubation tube 200.

  In the guide member 8 shown in FIG. 3A (hereinafter, this guide member may be referred to as “guide member 8A”), the width and depth of the guide portion 82 among the three guide members 8 are set to be the largest. It is a thing. A maximum outer diameter intubation tube 200 (hereinafter, this intubation tube may be referred to as “intubation tube 200A”) can be inserted into the guide member 8A.

  Further, in the guide member 8 shown in FIG. 3C (hereinafter, this guide member may be referred to as “guide member 8C”), the width and depth of the guide portion 82 are set to be the smallest. An intubation tube 200 having the minimum outer diameter (hereinafter, this intubation tube may be referred to as “intubation tube 200C”) can be inserted into the guide member 8C.

  3B (hereinafter, this guide member may be referred to as “guide member 8B”), the width and depth of the guide portion 82 are such that the guide portion 82 of the guide member 8A and the guide have the same width. It is set to an intermediate size between the guide portion 82 of the member 8C. The guide member 8B has an intubation tube 200 whose outer diameter is intermediate between the outer diameter of the intubation tube 200A and the outer diameter of the intubation tube 200C (hereinafter, this intubation tube is referred to as “intubation tube 200B”). Can be inserted).

  Then, any one of these three guide members 8 </ b> A to 8 </ b> C can be selected and attached to the support tool main body 4. Hereinafter, this will be described with an example of a method (action) of using the intubation assistance device 1.

Next, an example of a usage method (action) of the intubation support device 1 will be described.
The intubation support device 1 is used, for example, when the patient loses consciousness and it becomes necessary to insert the intubation tube 200 into the trachea.

  [1] First, depending on the patient, it is determined (selected) whether to use one of the intubation tubes 200A to 200C. For example, when it is decided to use the intubation tube 200B, the intubation support device 1 is assembled when inserting the intubation tube 200B.

  In assembling the intubation support device 1, first, the connector portion 52 of the scope 5 is connected to the connector portion 61 of the device body 2. Further, if necessary, for example, a suction tube or the like is inserted into the through hole 46 of the support tool main body 4 of the intubation support tool 3 and installed. Next, the scope 5 is inserted into the scope guide hole 44 of the support tool main body 4 of the intubation support tool 3, and the intubation support tool 3 is inserted between the mounting portion 23 of the casing 21 of the apparatus main body 2 and the operation ring 24. The proximal end portion 31 is inserted, the operation ring 24 is rotated in a predetermined direction, and the intubation support tool 3 is attached to the apparatus main body 2.

  [2] Next, the guide member 8B is mounted on the support tool main body 4 as described above to obtain a guide member mounting state. This mounting operation can be easily performed by the restriction means 32 and the lock mechanism 9.

  [3] Next, a switch (not shown) is operated to drive each part (white LED 55, CCD 53, display 71, etc.) of the intubation support apparatus 1, and the support tool body 4 of the intubation support tool 3 in the guide member wearing state is attached to the patient. Insert into the patient's trachea through the mouth.

  Specifically, the support tool body 4 is inserted into the patient's mouth while keeping the inside of the curved portion of the support tool body 4 along the tongue base. Then, while viewing and confirming the image displayed on the display 71, the patient's epiglottis is lifted to the tongue base side by the tongue piece 42 of the support tool body 4, and a predetermined portion on the distal end side of the support tool body 4 is moved to the tongue base portion of the patient. Abut. Thereby, an airway is secured.

  In this case, the tongue piece 42 (supporting tool main body 4) has optical transparency. Thus, when the patient's epiglottis is lifted to the base of the tongue by the tongue piece 42, the epiglottis can be imaged by the CCD 53 through the tongue piece 42, and the image can be displayed on the display 71. The tongue piece 42 has a plate shape. Thereby, the epiglottis can be lifted by the tongue piece 42 easily, quickly and reliably, and thus the airway can be secured easily, quickly and reliably.

  [4] Next, when the distal end of the support tool body 4 secures the airway, the intubation tube 200B is inserted into the guide portion 82 from the proximal end side of the guide member 8B, and the intubation tube 200B is pushed forward. Thereby, the intubation tube 200B is guided by the guide part 82 of the guide member 8B, and advances along the guide part 82 of the guide member 8B.

  Then, while viewing the image (including the image of the distal end portion of the intubation tube 200) displayed on the display 71, the distal end portion of the intubation tube 200B protruding from the guide portion 82 of the guide member 8B is inserted into the glottic fissure, and the trachea To reach. In addition, the guide portion 82 of the guide member 8B is formed so that the distal end portion of the intubation tube 200B naturally proceeds toward the glottic cleft, so that the intubation tube 200B is naturally guided to the glottic cleft. It has become. Thus, while viewing the image displayed on the display 71, the intubation tube 200B can be inserted into the trachea from the glottic cleft, and the intubation tube 200B is transformed into the glottic cleft by the guide portion 82 of the guide member 8B. Since the tube is naturally guided, the intubation tube 200 can be easily, quickly and reliably inserted into the trachea.

  Here, if the selected intubation tube 200B is incompatible and the intubation tube 200B is not inserted into the glottic cleft and cannot reach the trachea, it is necessary to replace the intubation tube 200B with another intubation tube 200A or 200C. There is. In this description, the intubation tube 200B is replaced with an intubation tube 200C.

  In this case, each part of the intubation assistance apparatus 1 is stopped by operating the switch. Then, the intubation tube 200B is removed from the guide member 8B, and the support tool main body 4 to which the guide member 8B is attached is once removed from the patient's mouth.

  [5] Next, with the support tool main body 4 still attached to the apparatus main body 2, the lock mechanism 9 is released as described above, and the guide member 8B is removed from the support tool main body 4.

  [6] Next, the guide member 8C is mounted on the support tool body 4 in the same manner as when the guide member 8B is mounted on the support tool body 4 from which the guide member 8B has been removed.

  [7] Next, the switch is operated again to drive each part of the intubation support apparatus 1, and the support tool body 4 of the intubation support tool 3 in the guide member wearing state is directed from the patient's mouth toward the patient's trachea. insert.

  [8] Next, when the distal end of the support tool main body 4 secures the airway, the intubation tube 200C is inserted into the guide portion 82 from the proximal end side of the guide member 8C, and the distal end portion of the intubation tube 200C is inserted into the glottis. Insert into the fissure and reach the trachea.

  [9] Next, in a state where the intubation tube 200C is inserted into the trachea, the intubation tube 200C is deformed, and the intubation tube 200C is detached from the guide portion 82 of the guide member 8.

[10] Next, while maintaining this state, the support tool main body 4 is removed (extracted) from the patient's mouth while the intubation tube 200C is left in the patient's mouth. The proximal end of the intubation tube 200C is connected to the ventilator, and air is fed into the trachea from the ventilator through the intubation tube 200C inserted into the trachea from the glottic fissure.
As described above, the intubation tube 200C can be intubated into the patient's trachea.

  As described above, according to the intubation support device 1, when the intubation support device 1 is in use, for example, when the intubation tube 200B is to be replaced with the intubation tube 200C, the support device body 4 remains attached to the device body 2. Thus, the guide member 8B can be exchanged with the guide member 8C, and the intubation tube 200C can be inserted into the patient's mouth via the exchanged guide member 8C. Therefore, the intubation tube replacement operation can be performed quickly. Moreover, the time required for intubation can be shortened, and the burden on the patient can be reduced.

  Further, as described above, the lock mechanism 9 is easy to attach and detach the guide member 8, and as a result, contributes to speeding up the intubation tube replacement operation. Further, the restriction means 32 makes it easier to attach to and detach from the lock mechanism 9.

  Further, the guide member 8 is one in which the intubation tube 200 slides along the guide portion 82, and thus is one of the members that are particularly worn among the members constituting the intubation support device 1, that is, the consumable It has become. In the intubation support device 1, since the consumable member is detachable, the consumable guide member 8 can be replaced with another new guide member 8.

  Further, the intubation support tool 3 is detachable from the apparatus main body 2, and further, the intubation support tool 3 can be disassembled into the support tool main body 4 and the guide member 8. 8 can be cleaned, disinfected, sterilized, etc. separately. Further, details such as the groove 43 of the support tool body 4 and the guide portion 82 of the guide member 8 can be reliably cleaned, disinfected, sterilized, and the like. Thereby, even when the support tool main body 4 and the guide member 8 are used again, infection (secondary infection) due to bacteria of the patient can be prevented, and safety is high.

  Moreover, in the intubation support tool 3, since the support tool main body 4 is made common and what is necessary is just to prepare several guide members 8 corresponding to the intubation tube 200 from which an outer diameter differs, the manufacturing cost at the time of manufacturing the intubation support tool 3 is reduced. Can be suppressed.

  As described above, the intubation support tool, the intubation support device, and the intubation support system of the present invention have been described with respect to the illustrated embodiments. Each component constituting the can be replaced with any component that can exhibit the same function. Moreover, arbitrary components may be added.

  Moreover, although the intubation support tool (support tool main body) can be inserted into the target site of the patient from the patient's mouth, the present invention is not limited thereto, and can be inserted from the patient's nasal cavity.

  For example, the apparatus main body may include an electronic data transmission apparatus that transmits image data to a hospital that is a patient transport destination via a wireless communication network. Thereby, the patient can be prepared for treatment in the hospital while the patient is being transported by an ambulance or the like.

  In the embodiment, the support tool main body of the intubation support tool is detachably attached to the apparatus main body. However, in the present invention, the support tool main body of the intubation support tool is attached to the device main body. It may be fixed (fixed) to the surface.
