  Here, when the respiratory tube is inserted from the patient's mouth, a method is used in which a tape is wound around the respiratory tube and then the tape is attached to the mouth. However, such a method for fixing the respiratory tube is physically unstable, and thus, when the patient becomes conscious, the patient is likely to come off due to the mouth movement or the like. Adults are anesthetized, so the mouth is very unlikely to move, but newborns, babies and infants cannot be anesthetized and if the patient is a newborn, infant or infant, when consciousness comes out However, the tape may come off with a slight movement. If the tape is removed, the tip of the respiratory tubing will not be able to maintain the position just before the bronchial branch, and in severe cases the respiratory tubing itself will fall out, which can be fatal. . In addition, for newborn babies, the skin is weak and is quickly peeled off even if firmly fixed with tape. In severe cases, the skin is peeled off with tape and cannot be fixed again with tape, resulting in a fatal result. It cannot be said that there is no possibility of inducing. The above problem is related to a newborn, an infant, and an infant. However, the problem is not limited to a newborn, an infant, and an infant.

  The present invention has been made to solve such a conventional problem, and an object of the present invention is to fix a respiratory tube that can easily maintain a distal end position of the respiratory tube at a predetermined position. An object of the present invention is to provide a fixture, a fixture manufacturing device, a fixture manufacturing program, and a computer-readable recording medium.

  The fixture for a respiratory tube according to the present invention covers a mouth of a patient and has a mouthpiece formed with an opening of a predetermined size, and in order to maintain the position of the mouthpiece with respect to the patient's head. A band portion that is provided integrally with the mouthpiece and is continuous with the mouthpiece continuously to the occipital region of the patient, wherein the mouthpiece has a respiratory tube inserted through the opening. In this state, the respiratory tube can be fixed.

  Further, the fixing device manufacturing apparatus according to the present invention is an apparatus for manufacturing a fixing device for a respiratory tube as described above, wherein an image pickup unit for picking up an image of a head including a mouth of a patient is picked up by the image pickup unit Based on the image of the head, a shape grasping means for grasping the shape of the head including the mouth of the patient, and the fixing tool so as to have a size based on the shape of the head grasped by the shape grasping means. And a three-dimensional printer to be manufactured.

  Further, the fixture manufacturing program according to the present invention is a program for causing a computer to function as the above-described fixture manufacturing apparatus, and the computer-readable recording medium according to the present invention stores the above-described fixture manufacturing program. It is a thing.

  According to the fixing device for a respiratory tube according to the present invention, the respiratory tube is provided with a band portion which is provided integrally with the mouthpiece and is continuous with the mouthpiece continuously to the occipital region of the patient. The respiratory tube can be fixed in a state where is inserted through the opening. Therefore, the respiratory tube is fixed to the mouthpiece without the respiratory tube being fixed to the mouth of the patient. Further, the position of the mouthpiece is maintained by the band portion without using tape. For this reason, even if the patient's mouth moves, the position of the mouthpiece becomes difficult to shift. Therefore, it is possible to easily maintain the distal end position of the respiratory tube at a predetermined position.

  Further, according to the fixture manufacturing apparatus, the fixture manufacturing program, and the computer-readable recording medium according to the present invention, the shape of the head including the mouth of the patient is grasped and grasped based on the captured image of the head. Since the fixing device is manufactured so as to have a size based on the shape of the formed head, the fixing device can be shaped to fit the individual patient, for example, the fixing device itself is displaced from the patient and mounted. Can be reduced.

It is a perspective view showing a fixture of a respiratory tube concerning an embodiment of the present invention. It is a lineblock diagram showing an outline of a fixture manufacturing device concerning an embodiment of the present invention.

  Hereinafter, the present invention will be described along preferred embodiments. Note that the present invention is not limited to the embodiments described below, and can be appropriately changed without departing from the spirit of the present invention. In addition, in the embodiments described below, some parts are not illustrated or described, but the details of the omitted techniques are within a range that does not conflict with the contents described below. It goes without saying that known or well-known techniques are applied as appropriate.

  FIG. 1 is a perspective view showing a fixture for a respiratory tube according to an embodiment of the present invention. 1 is for fixing a respiratory tube T1 extending from a ventilator or the like. This fixture 1 can be prepared in various sizes according to the size of the patient's body. The fixture 1 is formed of, for example, a soft resin (for example, a silicone resin), and includes a mouthpiece 10 that covers the mouth of a patient and a band 21 as shown in FIG. 1. The fixing tool 1 may be entirely or partially made of hard resin.

  The mouthpiece 10 is a part that covers the mouth of the patient. The mouthpiece 10 has an opening 11 at the center thereof. The opening 11 is, for example, a circular through hole into which the respiratory tube T1 is inserted, and is formed at a position facing the center of the mouth when the fixture 1 is attached to the patient.

  The band portion 21 is a portion provided for maintaining the position of the mouthpiece 10 with respect to the patient's head. The band portion 21 is provided integrally with the mouthpiece 10 (including connection such as bonding as well as integral), and is formed to extend from both sides of the mouthpiece 10. The band portion 21 can be fixed to the patient's head by tightening the band portion 21 having a circumferential shape together with the mouthpiece 10.

  Such a band portion 21 is designed to come into contact with the depression on the lower side of the occipital region of the patient. Further, the band portion 21 is designed so as not to contact the ear. Further, the band portion 21 has, for example, an elongated hole 21a formed at a central portion along the longitudinal direction. Thereby, it becomes possible to make one band 21b of the band portion 21 contact slightly above the dent on the lower back of the occipital region, and contact the other band 21c slightly below the dent on the lower occipital region. The structure makes it easy to prevent displacement in the vertical direction. The fixing device 1 has such a structure that it is not necessary to attach a tape to the patient's skin by such a band portion 21.

  The mouthpiece 10 is capable of fixing the respiratory tube T1. Examples of the fixing method include sticking with a tape, fixing with a clip, and press fitting. In particular, in the present embodiment, the diameter of the opening 11 of the mouthpiece 10 is equal to or slightly smaller than the outer diameter of the specific respiratory tube T1 to be used for the patient. For this reason, the respiratory tube T1 exerts a frictional force on the inner wall of the opening 11 and is hardly detached. Furthermore, if the diameter of the opening 11 is smaller than the outer diameter of the specific respiratory tube T1, the respiratory tube T1 is pressed into the opening 11, so that the respiratory tube T1 is further fixed to the opening 11. (In addition, tapes and clips may be used). The mouthpiece 10 is preferably made of a material having a higher hardness than the band 21 so as to easily fix the respiratory tube T1.

  The specific respiratory tube T1 to be used for the patient differs depending on the size of the patient's body. For example, the respiratory tube T1 used for adult men and the respiratory tube T1 used for newborns, babies and infants are used. The respiratory tube T1 differs in thickness and length. Therefore, it is determined that a general adult male should use a respiratory tube T1 having a length of, for example, XX mm, an outer diameter of YY 1 mm, and an inner diameter of ZZ 1 mm. It has been determined that a respiratory tube T1 of XX 2 mm, outer diameter YY 2 mm, and inner diameter ZZ 2 mm should be used (the length may be different for neonates, babies and infants, etc.). A plurality of types of the fixture 1 according to the present embodiment are also prepared so as to be able to cope with the difference in the size of the patient's body, and a specific type suitable for the size of the patient's body is selected during actual use. You. Accordingly, in the relationship between the fixture 1 selected according to the size of the patient's body and the respiratory tube T1 selected according to the size of the patient's body, the diameter of the opening 11 is equal to the outer diameter of the respiratory tube T1. It is the same or smaller than the outer diameter.

  To describe specific numerical values, the respiratory tube T1 has, for example, an outer diameter of 6 mm or more and 12 mm or less. Therefore, the diameter of the opening 11 is, for example, not less than 4 mm and not more than 10 mm.

  In addition, the mouthpiece 10 is provided with a display unit 12 on its surface (at a position adjacent to the opening 11). The display unit 12 indicates the insertion amount of the respiratory tube T1 from the position of the opening 11. In other words, by inserting the respiratory tube T1 into the opening 11 according to the insertion amount of the display unit 12, the distal end position of the respiratory tube T1 is easily located at a position just before the bronchial branch of the patient. Here, the length from the mouth to just before the bronchial branch also varies depending on the size of the patient's body. Therefore, different numerical values are described on the display unit 12 according to the type of the fixture 1 used. That is, the insertion amount of an adult male is displayed on the display unit 12 for the fixture 1 for an adult male, and the insertion amount of a newborn, baby, and an infant is displayed on the display unit 12 for the fixture 1 for a newborn, an infant, and a baby. Will be done.

  Further, the mouthpiece 10 is configured not to contact the nose and chin unlike a normal mask. Therefore, the upper end of the mouthpiece 10 is located between the nose and the mouth. Furthermore, since the mouthpiece 10 has a structure in which the chin is exposed without covering, the rubbing caused by the movement of the mouth can be prevented, and a shape suitable for a newborn with particularly weak skin can be obtained.

  Next, an example of a method of attaching the fixing device 1 according to the present embodiment to a patient will be described. First, an appropriate type of fixture 1 according to a patient's body is prepared. Next, the fixture 1 is attached to the patient. At this time, the band 21 is stretched while the mouthpiece 10 is positioned at the mouth of the patient, and is wound around the lower part of the back of the patient's occiput.

  Next, the target respiratory tube T1 is selected, and the respiratory tube T1 is inserted into the mouth of the patient through the opening 11. Then, when the insertion amount into the opening 11 becomes the same as the insertion amount described on the display unit 12, the insertion operation is completed. Thereafter, the respiratory tube T1 is fixed to the mouthpiece 10 with a tape or a clip. Thus, the attachment of the fixture 1 to the patient is completed.

  Thus, according to the fixture 1 of the respiratory tube T1 according to the present embodiment, the band portion 21 which is provided integrally with the mouthpiece 10 and is continuous with the mouthpiece continuously to the back of the patient. The mouthpiece 10 is configured such that the respiratory tube T1 can be fixed in a state where the respiratory tube T1 is inserted into the opening 11. Therefore, the respiratory tube T1 is fixed to the mouthpiece 10 without fixing the respiratory tube T1 to the mouth of the patient. The position of the mouthpiece 10 is maintained by the band 21 without using a tape. Therefore, even if the patient's mouth moves, the position of the mouthpiece 10 is less likely to shift. Therefore, it is possible to easily maintain the distal end position of the respiratory tube T1 at a predetermined position.

  Further, since the insertion amount of the respiratory tube T1 is displayed on the surface of the mouthpiece 10, it becomes clear how much the respiratory tube T1 should be inserted, and the distal end position of the respiratory tube T1 is determined as an appropriate position. It can be easier.

  In addition, since the diameter of the opening 11 is equal to or smaller than the outer diameter of the respiratory tube T1, the respiratory tube T1 exerts a frictional force on the inner wall of the opening 11, and maintains the position. Easier to do. Therefore, it is possible to easily maintain the distal end position of the respiratory tube T1 at a predetermined position.

  Next, an apparatus for manufacturing a fixture according to an embodiment of the present invention will be described. FIG. 2 is a configuration diagram schematically showing the fixture manufacturing apparatus according to the embodiment of the present invention.

That is, based on the captured image, the shape grasping unit 131 may determine, for example, the length from the nose to the chin, the length from the nose to the mouth, the position of the mouth between the nose and the chin, the size of the head, and the like. The shape of the object is to be grasped.

  The control device 130 generates data of the fixture 1 as a dedicated product by grasping the shape in this manner. That is, the control device 130 determines the length of the band portion 21 or the size of the mouthrest portion 10 based on the shape grasp. The control device 130 may also determine the shape of the mouthpiece 10 such as being slightly horizontal or vertical.

  The first calculator 132 calculates the insertion amount of the respiratory tube T1 from the opening 11 based on the height data of the patient. When the whole body of the patient is imaged by the camera 110, the first calculation unit 132 calculates height data based on the captured image, and calculates the insertion amount of the respiratory tube T1 based on the height data obtained by the calculation. calculate. Further, when height data of a patient is input to the input unit 120, the first calculation unit 132 may calculate the insertion amount of the respiratory tube T1 based on the input height data. Further, the first calculation unit 132 may calculate the height, not only the height data, but also the width and weight of the patient.

  The insertion amount calculated by the first calculation unit 132 in this manner is described on the surface of the mouthrest unit 10 as the display unit 12 described with reference to FIG.

  The second calculation unit 133 calculates the outer diameter of the respiratory tube T1 based on the height data of the patient. When the whole body of the patient is imaged by the camera 110, the second calculator 133 calculates height data based on the captured image, and calculates the outer diameter of the respiratory tube T1 based on the height data obtained by the calculation. calculate. Further, when the height data of the patient is input to the input unit 120, the second calculation unit 133 may calculate the insertion amount of the respiratory tube T1 based on the input height data. Furthermore, the second calculating unit 133 may calculate the height, not only the height data, but also the width and weight of the patient.

  The three-dimensional printer 140 manufactures the fixture 1 so as to have the opening 11 having the same size as the outer diameter calculated by the second calculator 133 or a size smaller by a predetermined amount than the outer diameter.

  Thus, according to the fixture manufacturing apparatus 100, the fixture manufacturing program, and the recording medium on which the program is recorded according to the present embodiment, the head including the mouth of the patient based on the captured image of the head Since the shape of the part is grasped and the fixing device 1 is manufactured so as to have a size based on the grasped head shape, the fixing device 1 having a shape suitable for an individual patient can be obtained. Accordingly, it is possible to reduce a possibility that the fixing tool 1 itself does not fit the patient and the fixing tool 1 is easily displaced by the action of an external force.

  In addition, since the insertion amount of the respiratory tube T1 calculated based on the height data is displayed on the surface of the mouthpiece 10, the insertion amount of the respiratory tube T1 is significantly different from that of a newborn baby, an infant, and an infant. Even in such a case, it becomes clear how much the respiratory tube T1 is to be inserted based on the display of the insertion amount based on the height data, and the fixing device 1 that can easily set the distal end position of the respiratory tube T1 to an appropriate position is used. Can be provided.

  In addition, since the opening 11 having the same size as the outer diameter of the respiratory tube T1 calculated based on the height data or having a size smaller by a predetermined amount than the outer diameter is formed, as in the case of a newborn, an infant, an infant and an adult, Even if the diameter of the respiratory tube T1 is different, it is easy to select the respiratory tube T1 having an appropriate diameter based on the height data, and the fixing tool 1 that allows the user to select an appropriate respiratory tube T1 is provided. can do.
