Description

  The present invention relates to an airway securing mask for supplying oxygen to a patient who is difficult to secure an airway.

  2. Description of the Related Art Conventionally, an artificial respiration mask having a connection port for an intake / exhaust hose and including a dome-shaped mask body that hermetically covers a patient's nostril, mouth, and the periphery thereof is known.

  For example, in Patent Document 1, a bulging composed of a base member made of a stretchable flexible material that abuts the mask body in a state of following the concavo-convex surface of the face, and a material that can see the vicinity of the nose from the outside. And a central member. When a breathing difficulty, cardiopulmonary arrest, etc. require supplementary breathing, an auxiliary ventilation that sends oxygen through bag mask ventilation, etc. is performed when surgical anesthesia is introduced. . With this auxiliary ventilation, oxygen can be temporarily delivered to the patient's lungs to avoid risking the patient, calling for support, waiting for anesthesia to wake up, and other means of securing the airway. Or you can explore.

  However, if the patient loses consciousness due to a coma or general anesthesia, etc., if the airway is not secured, oxygen can be forced into the airway even if oxygen is forced into the artificial respiration mask by bag mask ventilation. May not be delivered, oxygen may be delivered to the esophagus, the stomach may swell, and pneumonia may be induced by vomiting. Also, if oxygen is not pumped into the airways, the patient is at risk due to hypoxia.

  The reason for the obstruction of the trachea is, for example, that the tongue base falls to block the airway, the epiglottis falls to block the airway, and obesity or the like blocks the airway by the weight of fat around the neck.

  During this tracheal occlusion, the tip of the laryngoscope is inserted into the valley of the epiglottis between the patient's tongue base and the pharyngeal surface of the epiglottis, the tongue base and epiglottis are lifted, the larynx is expanded, the glottis is visually confirmed, and the endotracheal tube There is also a method of intubating and sending oxygen into the patient's lungs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show an airway securing mask 1 according to an embodiment of the present invention, and the airway securing mask 1 includes a dome-shaped mask body 2 made of, for example, a colorless and transparent resin molded product. The mask main body 2 is flexible in order to be deformed in accordance with the face 51 of the patient 50 to increase the sealing degree, and a flange 2a having an oval outer shape is provided at the lower end thereof. An annular cushion portion 3 that serves as a cushion by being filled with air is attached to the lower surface of the flange 2a. Although not shown, a valve for filling the cushion part 3 with air may be provided on the flange 2a. A pipe-like connection port 5 to which an intake / exhaust hose 4 connected to an oxygen supply device (not shown) is connected is projected from the upper center of the mask body 2. For example, the oxygen supply device includes a bag (not shown), and is configured such that oxygen is supplied to the airway securing mask 1 when the bag is gripped. The connection port 5 penetrates the mask main body 2 in the vertical direction, but may be provided in the mask main body 2 in the horizontal direction so as to face either the left or right. As shown in FIG. 3, the airway securing mask 1 is configured to press the cushion portion 3 against the face 51 of the patient 50 and cover the nostril 52, the mouth 53 and the periphery thereof in an airtight manner.

  A blade 10 is rotatably supported on the mask body 2. The blade 10 is made of, for example, a resin molded product, and the tip 10a is curved. When the airway securing mask 1 is attached to the patient 50, the tip 10a is inserted from the mouth 53, and the length thereof is in the vicinity of the epiglottis 54, that is, between the tongue base 55 of the patient 50 and the pharyngeal surface 54a of the epiglottis 54. It is inserted into the epiglottis valley 56. A base end 10 b of the blade 10 protrudes from the opening 2 b formed in the mask body 2 to the outside of the mask body 2. The shape and size of the opening 2b are determined by the width and thickness of the base end 10b and the moving range. In this embodiment, for example, it has a substantially rectangular shape. By forming the blade 10 from a resin molded product, the shape of the blade 10 can be easily designed, and it is lightweight and easy to handle.

  The blade 10 includes a rotating shaft 11 that extends to the left and right near the base end 10b in the middle portion in the longitudinal direction. The rotating shaft 11 may be formed integrally with the same resin material as the blade 10 or may be formed in-mold with a metal material. The rotation shaft 11 is rotatably inserted into a boss portion 12 that bulges inward from the inner surface of the mask body 2. As a result, the blade 10 rotates in the vertical direction around the rotation shaft 11. Since the distal end 10a side is longer than the proximal end 10b side when viewed from the rotation shaft 11, the blade 10 is lowered downward by its own weight. Further, the rotating shaft 11 may be detachable from the boss portion 12. If a plurality of blades 10 of different sizes are prepared so as to be detachable, the blades 10 can be freely replaced in accordance with the patient 50.

  Then, when the proximal end 10b side of the blade 10 is pushed down, the tongue base 55 and the epiglottis 54 are lifted by the distal end 10a so as to deploy the larynx.

  The opening 2b provided in the mask body 2 and the base end 10b of the blade 10 are covered with a bag-like sealing member 13. The sealing member 13 is made of, for example, a bellows-like flexible member. If the sealing member 13 is bonded to the mask body 2 and the base end 10b of the blade 10, the sealing member 13 expands and contracts in accordance with the movement of the blade 10, so that the sealing member 13 can be reliably sealed. It is. On the other hand, the sealing member 13 and the base end 10b are not adhered to each other, but are closely adhered with an elastic material.

-Operation of airway mask-
Next, the operation of the airway securing mask 1 according to the present embodiment will be described.

  First, when the patient 50 is unable to breathe spontaneously due to difficulty breathing, cardiopulmonary arrest, etc., or when the patient 50 is anesthetized during thoracoabdominal incision surgery and cannot breathe spontaneously by administration of a muscle relaxant, etc. It is necessary to prevent the patient 50 from becoming hypoxic by sending oxygen into the lung 58 of the patient 50.

  First, as shown in FIG. 3, the patient 50 is laid, for example, a head is placed on a pillow in which a towel 59 is folded. Then, the jaw is lifted to secure the airway 57.

  When the patient 50 loses consciousness, even if the jaw is lifted, the tongue base 55 falls and blocks the airway 57, the epiglottis 54 falls and closes the airway 57, and obesity etc. due to the weight of fat around the neck, etc. The airway 57 is blocked.

  When the airway 57 is blocked as described above, oxygen is not successfully sent to the airway 57 simply by pressing the conventional mask against the face 51 of the patient 50 and oxygen is sent to the esophagus 60 in some cases. The stomach 61 may swell and pneumonia may be induced by vomiting.

  Therefore, the airway securing mask 1 of this embodiment is used. First, the tip 10 a of the blade 10 is inserted from the mouth 53 of the patient 50.

  Then, the mask body 2 covers the nostril 52, the mouth 53 and the periphery of the patient 50 in an airtight manner. Then, the distal end 10 a is inserted around the pharyngeal surface 54 a of the epiglottis 54 of the patient 50.

  Next, the base end 10b of the blade 10 is pushed down with the side of the thumb or the tip while pressing the chin of the patient 50. Then, a force acts in a direction in which the mask body 2 is brought into close contact with the face 51 of the patient 50, and the degree of sealing of the mask body 2 is ensured. Since the base end 10b of the blade 10 is directly operated, the operation is easy and there are few operation mistakes, and the number of parts of the airway securing mask 1 is reduced, so that the manufacturing is facilitated and the manufacturing cost is reduced.

  Then, the tip 10a of the blade 10 is rotated upward, the epiglottis valley 56 is pushed up, and the tongue base 55 and the epiglottis 54 are lifted. For this reason, a larynx is developed and the airway 57 is ensured reliably. Thus, a hypoxic state is avoided by sending oxygen into the lungs 58 by grasping the bag while the airway 57 is securely secured. During this time, when the patient's consciousness returns, for example, the patient 50 can breathe at his own will or seek another means such as tracheal intubation or tracheostomy.

  In the present embodiment, the length of the blade 10 is selected according to the patient 50 in advance. If the blade 10 of the prepared airway securing mask 1 is not appropriate in length, it can be replaced by fitting another blade 10 having a different length into the boss portion 12. As described above, the optimal position to be pressed at the tip of the blade 10 for laryngeal deployment differs depending on the patient 50. However, if the blade 10 can be replaced, it is not necessary to replace the entire airway securing mask 1 according to the patient 50. Storage space and cost are reduced.

  Therefore, according to the airway securing mask 1 according to the present embodiment, the blade 10 is rotatably supported by the mask body 2, the distal end 10a is inserted into the epiglottis valley 56 of the patient 50, and the proximal end 10b side is pushed down. Thus, the tongue base 55 and the epiglottis 54 are lifted by the tip 10a to deploy the larynx, so that the airway 57 of the patient 50 can be easily secured and the auxiliary ventilation can be performed safely and reliably with a simple structure. .

-Modification 1 of embodiment-
4 and 5 show an airway securing mask 101 according to the first modification of the embodiment of the present invention, which is different from the above embodiment in that the method of pressing the base end 110b of the blade 110 is different. In addition, in each modification below, the same code | symbol is attached | subjected about the same part as FIGS. 1-3, and the detailed description is abbreviate | omitted.

  The base end 110b of the blade 110 of this modification is shorter than the base end 10b of the blade 10 of the above-described embodiment, and is accommodated inside the mask body 2. The base end 110b is divided into two parts, and the connecting shaft 110c is coupled to the gap.

  On the other hand, the airway securing mask 101 of this modification has a turning lever 102 that is rotatably supported by the mask body 2. The pivot lever 102 has a tip 102 a protruding from the opening 2 b formed in the mask body 2 to the outside of the mask body 2. A lever-side rotation shaft 103 extending in the left-right direction protrudes in the middle in the longitudinal direction of the rotation lever 102, and this lever-side rotation shaft 103 is rotatable to a lever-side boss portion 112 provided in the mask body 2. It is supported. The base end 102b of the rotating lever 102 is formed with a connecting elongated hole 102c that is tapered and extends in the longitudinal direction. The connecting shaft 110c of the blade 110 is slidably connected to the long hole 102c.

  Similarly to the above embodiment, the opening 2b provided in the mask body 2 and the rotation lever 102 are covered with a bag-like sealing member 13.

  Next, the operation of the airway securing mask 101 according to this modification will be described only with respect to differences from the above embodiment.

  After the blade 110 is inserted into the mouth 53 of the patient 50, when the turning lever 102 is turned upward as shown in FIG. 4, the base end 102b is turned downward about the lever-side turning shaft 103.

  Then, the base end 110b of the blade 110 is pushed down while the connecting shaft 110c moves downward in the long hole 102c of the base end 102b.

  As a result, the tip 110a of the blade 110 rotates upward, pushes up the epiglottis 56, and the tongue base 55 and the epiglottis 54 are lifted.

  Thus, the blade 110 is indirectly rotated by rotating the rotation lever 102. By rotating the blade 110 through the rotation lever 102, the base end 110b of the blade 110 does not protrude from the mask body 2, so that the degree of freedom of the position and size of the opening 2b of the mask body 2 is increased. It is increasing. For this reason, the position of the opening 2b can be changed by changing the positions of the lever side rotation shaft 103 and the connecting shaft 110c, and the width and thickness of the rotation lever 102 can be changed to change the size of the opening 2b. You can change that.

  And since the rotation lever 102 and the blade 110 are connected by the connecting shaft 110c, it is hard to break, and if the rotation lever 102 is rotated, the blade 110 is reliably rotated.

  In this modification, the base end 110b of the blade 110 and the base end 102b of the rotating lever 102 are connected, but it is not always necessary to connect them, and the base end 102b of the rotating lever 102 does not necessarily connect. You may make it push down the base end 110b.

  Although not shown, when the lever-side rotation shaft 103 is disposed above the connecting shaft 110c and the rotation lever 102 is pushed down, the base end 102b is positioned closer to the distal end 102a than the lever-side rotation shaft 103. The base end 110b of the blade 110 can also be pushed down. In this way, the direction in which the mask main body 2 is pressed and the direction in which the rotary lever 102 is pressed coincide with each other as in the above embodiment, and the mask main body 2 can be easily pressed against the patient 50.

-Modification 2 of embodiment-
6 and 7 show the use of the airway securing mask 201 according to the second modification of the embodiment of the present invention, which differs from the above embodiment in that the method of pressing the base end 210b of the blade 210 is different.

  The base end 210b of the blade 210 of the present modification is also housed inside the mask body 2 as in the first modification. The airway securing mask 201 of this modification has a push-down button 202 that slides in the vertical direction. In this push-down button 202, for example, the tip 202a is circular so that it can be easily pushed with a finger. The opening 2b is formed in a cylindrical boss, and a push-down button 202 is inserted into the opening 2b. The base end 202b is thicker than the intermediate part 202c inserted into the opening 2b, which also serves as a stopper. By making the tip 202a or the base end 202b detachable, the push-down button 202 can be inserted into the opening 2b, and by doing so, the tip 202a protrudes from the opening 2b to the outside of the mask body 2.

  In this way, the push-down button 202 can be slid up and down with respect to the mask body 2. By pushing down the push-down button 202, the base end 202 b of the push-down button 202 presses the base end 210 b of the blade 210. The blade 210 is configured to rotate upward.

  Similarly to the above embodiment, if the opening 2b provided in the mask body 2 for operating the blade 210 is covered with the push-down button 202 by the bag-like sealing member 13, the operability of the blade 210 is not deteriorated. However, in this modification, an O-ring 203 is fitted on the outer periphery of the intermediate portion 202c. The O-ring 203 slides on the inner surface of the opening 2b, so that the inside of the mask body 2 and the outside are sealed.

  Also in this modified example, by pushing down the push-down button 202, the base end 210b of the blade 210 is rotated downward, whereby the distal end side 210a is pushed upward and the airway 57 is secured. Since the push-down button 202 only moves up and down, the opening 2b provided in the mask body 2 can be made small, and airtightness can be easily secured.

—Modification 3 of Embodiment—
FIG. 8 shows a state in which an airway is secured by the airway securing mask 301 of Modification 4 of the embodiment of the present invention, which differs from the above embodiment in that the shape of the tip 310a of the blade 310 is different.

  Unlike the above-described embodiment, the tip 310a of the blade 310 of this modification extends linearly. The length of the tip 310a is set to reach the laryngeal surface 54b of the epiglottis 54 of the patient 50 when the blade 310 is inserted.

  The tip 310a of the blade 310 is inserted from the mouth 53 of the patient 50 to the laryngeal surface 54b of the epiglottis of the patient 50, and the mask body 2 is pressed against the face 51 of the patient 50 so that the nostrils 52, the mouth 53 and the surroundings of the patient 50 are airtight. The base end 310b side of the blade 310 is pushed down with the side surface of the thumb or the tip in the state where it is covered.

  Then, the tip 310a of the blade 310 is rotated upward, the epiglottis 54 is directly pressed and lifted upward, and the tongue base 55 is lifted accordingly.

  For this reason, a larynx is developed and the airway 57 is ensured reliably. In this state, oxygen is reliably fed into the airway 57 of the patient 50 even if it is difficult to secure the airway by sending oxygen by grasping the bag or the like.

(Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

  That is, in the above embodiment, since the rotation shaft 11 is fixed to the blade 10, the length of the blade 10 cannot be adjusted, but the blade 10 may be configured to be adjustable in length. For example, as shown in FIG. 9, the left and right intermediate portion 11a of the rotation shaft 11 is a flexible member, and the blade 10 is slid in the longitudinal direction in the left and right intermediate portion 11a, so that the rotation shaft 11 The length up to the tip 10a can be adjusted. This makes it usable for many patients. Therefore, since the length can be adjusted without replacing the blade 10, the management of the parts is facilitated and the usability is improved. In addition, the method of length adjustment is not limited to this, For example, it is good also as a telescopic type by overlapping the cylindrical member from which an external shape differs.

  Further, as shown in FIG. 10, the blade 410 may be hollow, and an illumination device that illuminates the inside of the larynx may be mounted therein. For example, as in a known laryngoscope, there is a method in which the optical fiber 401 extends along the tip opening 402 of the blade 410. By generating light from the tip of the optical fiber 401, the larynx can be deployed more easily and safely.

  Furthermore, in the above embodiment, oxygen is forcibly supplied to the airway securing mask 1 by grasping a bag supplied with oxygen. However, the present invention is not limited to this method, and oxygen is automatically supplied instead of manually. You may make it supply.
