Description

  The present invention has a substantially cylindrical shape as a whole, and an occlusal recess is formed on the outer peripheral side of the cylinder so as to accommodate a part of the teeth or a part of the gums of the inspected person, and on the inner peripheral side of the cylinder. A suction tube that can be attached to a mouthpiece formed with an insertion guide portion for guiding an endoscope in the examiner's oral cavity and that guides a suction object such as saliva stored in the oral cavity of the examinee to the suction means. The present invention relates to a mouthpiece suction tool.

  Conventionally, when examining the stomach, large intestine, etc. of an examinee, a medical instrument called an “endoscope” for observing the inside of the human body is inserted into the examinee's body and the internal image is output to the outside. Has been done. In this specification, the endoscope means an “upper gastrointestinal endoscope” for observing the upper gastrointestinal tract up to the esophagus, stomach, and duodenum.

  A conventional endoscope includes an elongated portion having flexibility, and the elongated portion is orally inserted into the human body from the oral cavity of the subject. When the endoscope is inserted into a human body, there is a risk that the endoscope may be bitten off by an examinee who feels pain or discomfort. Therefore, when an endoscope is used, the endoscope is protected by biting an endoscope mouthpiece with an examinee.

  The endoscope mouthpiece has a substantially cylindrical shape so that the main body can be held in the mouth of the examinee, and an insertion guide portion for inserting the endoscope is provided inside the cylinder (of the present application). The insertion guide portion surrounds the endoscope, thereby preventing the endoscope from being damaged and assisting the smooth insertion of the endoscope into the human body. Thus, the endoscope mouthpiece is an essential instrument for endoscopy.

  By the way, in the oral cavity of the subject, saliva and the like are easily secreted and collected with the insertion of the endoscope. And the collected saliva etc. will flow out of an oral cavity, and will give a subject discomfort and stress.

  In elderly subjects, the salivary gland gradually shrinks, and the viscosity of accumulated saliva is often high, making it difficult to forcibly vomit, and the worst situation is Saliva or the like may flow into the trachea, causing pneumonia and causing sepsis.

  Therefore, conventionally, a suction device has been proposed in which a tube for sucking saliva or the like is attached to an endoscope mouthpiece, and the saliva or the like accumulated in the oral cavity is positively removed (for example, Patent Document 1).

Utility Model Registration No. 3064136

  The suction tool described in Patent Document 1 is a single suction that has flexibility so that the band-shaped attachment portion is inserted inside the mouthpiece and straddles both end portions of the attachment portion that hangs down from the front and rear sides of the mouthpiece. The pipe | tube is attached along the front-back direction of a mouthpiece (refer FIG.1 and FIG.2 of patent document 1).

  By the way, since the suction tube is inserted into the oral cavity of the person to be inspected, it is replaced every time an endoscopic inspection is performed from the viewpoint of hygiene. On the other hand, since the mouthpiece for endoscope is formed of a hard material such as synthetic resin, it may be reused after being disinfected from the viewpoint of effective use of resources. From this point of view, the suction tool preferably has a structure that can be attached to and detached from the endoscope mouthpiece.

However, in the suction tool described in Patent Document 1, it cannot be said that “attachment” and “removal” of the suction tube to the endoscope mouthpiece are easy because of the structure. For this reason, there is a problem that the attachment becomes insufficient, and the suction tube falls off the mouthpiece at the time of the endoscopic inspection, and the endoscopic inspection cannot be performed quickly due to troublesome attachment work.
Also, with regard to the removal of the suction tube, it takes time for the removal work, and in some cases, it is disposed of together with the endoscope mouthpiece, resulting in a waste of resources.

In addition, in the suction tool described in Patent Document 1, due to the structure, saliva or the like is sucked by a suction hole formed in the distal end portion of one suction tube, that is, the suction point is “point”. Therefore, for example, saliva collected in a plurality of locations in the oral cavity cannot be sucked at the same time, and there is a problem that it takes time for the suction operation such as moving the tip of the suction tube and sucking it individually. .
Moreover, in the suction tool described in Patent Document 1, it is difficult to adjust the length of the portion to be inserted into the oral cavity of the examinee due to the structure. For example, the portion to be inserted is longer than necessary. The tip of the suction tube may reach the throat and be damaged.

  In addition, in the suction device described in Patent Document 1, since the exclusion means such as saliva is entrusted to a single suction tube, saliva with high consistency that is often found in elderly subjects, If a part of the suction tube is blocked, suction is impossible.

  The present invention has been made in view of such circumstances, and includes a suction tube that can be attached to an endoscope mouthpiece and guides saliva or the like stored in the oral cavity of the subject to suction means. Flexible, bent so that both ends in the longitudinal direction approach each other, and joins the pipe line formed by the both ends via a connecting part to communicate with the suction means, which is farthest from the connecting part A plurality of suction holes are drilled in the farthest bending area, and the suction pipes that are bent and face the connection part side are partially tied together at multiple places via the binding parts, and the mouthpiece body between the binding parts The mouthpiece suction allows the suction object to be sucked reliably by making it possible to attach and detach the mouthpiece more easily than in the past by forming a separation space for fitting to the mouthpiece. The purpose is to provide ingredients.

  The mouthpiece suction tool according to the present invention has a substantially cylindrical shape as a whole, and an occlusal recess is formed on the outer peripheral side of the cylinder so as to accommodate a part of the teeth of the examinee or a part of the gums. In addition, suction of saliva or the like stored in the oral cavity of the subject, which can be attached to a mouthpiece in which an insertion guide portion for guiding the endoscope into the oral cavity of the subject is formed on the inner peripheral side of the cylinder A mouthpiece suction tool comprising a suction tube for guiding an object to suction means, wherein the suction tube is bent so that both end portions in the longitudinal direction are close to each other by being flexible, A connecting portion that joins the pipe lines formed by both ends to communicate with the suction means, and a plurality of suction holes for sucking the suction object into the pipe, which is drilled in the farthest bent region farthest from the connecting portion The suction pipe that is bent and faces the connecting portion side A bundling portion that partially binds the suction pipes, and the bundling portion ties the suction pipes at a plurality of locations to form a space for fitting the mouthpiece between the bundling locations. It is characterized by being.

  In the present invention, the suction pipe for sucking the suction object stored in the oral cavity of the examinee is bent so that both end portions in the longitudinal direction approach each other, and the pipe lines at these both end portions connect the connection portions. The suction holes for sucking objects to be sucked are provided in the area farthest from the connecting portion by joining and connecting to the suction means, thereby forming a plurality of pipe lines leading from the suction holes to the suction means. Therefore, even if the suction pipe of one system is blocked, the suction object can be guided to the suction means via the suction pipe of another system.

  Further, in the present invention, the binding portion ties the suction tubes together at a plurality of locations to form a spacing space between the binding locations, and this spacing space fits into the mouthpiece. Attachment / detachment to / from the mouthpiece is easier than before. As a result, the suction tube can be reliably and quickly attached to the endoscope mouthpiece. In addition, the suction tube can be easily and quickly removed from the endoscope mouthpiece, and for example, a situation in which the endoscope mouthpiece is discarded together with the suction tube can be avoided.

  Further, in the present invention, since the plurality of suction holes are curved, the holes are drilled as compared with the case where the suction tool described in Patent Document 1 is drilled at the rod-shaped tip. Since the positions can be effectively arranged in a narrow area, these drilled positions surely reach the portion where saliva produced in the oral cavity of the examinee is easily stored. Further, since the puncture site is curved, the suction site can be grasped by a “surface” wider than “point”. For example, saliva accumulated in a plurality of locations in the oral cavity is simultaneously sucked.

  Moreover, in this invention, even if it is a case where one suction hole is obstruct | occluded by the several suction hole being pierced, a suction | inhalation target object is attracted | sucked from the remaining suction holes. In addition, by dispersing the suction pressure by the plurality of suction holes, a situation in which the suction holes are attracted to the oral cavity wall and a suction mark is difficult to occur.

  Further, in the mouthpiece suction tool according to the present invention, the plurality of binding portions are movable along the longitudinal direction of the suction tube between the connection portion and the farthest bending region. Features.

In the present invention, since the binding portion is movable, the binding location can be freely changed, and the separation distance of the separation space formed between the binding locations can be changed. The distance is extended to facilitate the “attachment” and “removal” of the suction tube to the mouthpiece, and the distance is shortened to fasten the suction tube to the mouthpiece.
In addition, by freely changing the binding location, it is possible to change not only the separation space but also the bending of the suction hole drilling site, so that the drilling site should be inserted according to the size of the oral cavity to which the hole is to be inserted. The ring size of the substantially annular portion formed by the drilled portion is adjusted. In particular, the size of the oral cavity is effective because the size varies depending on age or sex.

  Furthermore, in the mouthpiece suction tool according to the present invention, at least a part of the plurality of suction holes is formed at a position where the mouthpiece does not come into contact with the oral cavity wall when inserted into the oral cavity of the subject. It is characterized by being.

  In the present invention, at least a part of the suction hole is formed at a location where it does not come into contact with the oral cavity wall of the subject, so that all the suction holes are blocked by the oral cavity wall of the subject. A situation in which the suction object cannot be sucked is avoided.

  According to the present invention, attachment to and removal from a mouthpiece can be facilitated as compared with the prior art, and at the same time, a suction object can be reliably sucked.

It is a back view which shows the whole structure of the suction tool for mouthpieces which concerns on this invention. It is a perspective view which shows the state which attached the mouthpiece suction tool shown in FIG. 1 to the mouthpiece for endoscopes. It is the figure seen from the oral cavity side which shows the state which has inserted the suction tool for mouthpieces shown in FIG. It is the figure seen from the oral cavity which shows the state which inserted the suction tool for mouthpieces shown in FIG. 1 in the to-be-tested person's oral cavity.

  A mouthpiece suction tool according to the present invention will be described below with reference to the drawings showing this embodiment. FIG. 1 is a back view showing the entire structure of the mouthpiece suction tool according to the present invention. In FIG. 1, 1 is a suction tool. The suction tool 1 includes a suction pipe 10, a connection part 11 connected to both end portions 100 of the suction pipe 10, and a binding part 12 that binds a part of the suction pipe 10.

  The suction tube 10 is made of, for example, silicone rubber, and has flexibility so that it can be bent in the longitudinal direction. The suction tube 10 is formed so that the outer diameter of the tube is about 3 to 6 mm. The suction tube 10 includes both end portions 100 in the longitudinal direction, the farthest bending region 101, a binding portion 102, and a suction hole 103.

  Further, the suction tube 10 is bent so as to be substantially U-shaped so as to be substantially left-right symmetric based on a virtual center line (not shown) passing through the farthest bending region 101, and both ends 100 are bent by bending. Are close together. The suction tube 10 is bent so that the farthest bent region 101 is formed at a position farthest from the connection component 11 connected to the both ends 100. By bending the suction pipe 10, the pipe body faces the connecting part 11 side from the farthest bending area 101, and a plurality of portions of the pipe body are tied together by the binding parts 12, and the bent state is maintained. In the present specification, “plurality” means two or more.

  Further, the suction pipe 10 is formed so that the farthest bending region 101 is substantially annular by being bound by the binding component 12. A plurality of suction holes 103 are formed in the farthest bending region 101 so as to be effectively arranged. Each suction hole 103 is formed to have a diameter of about 2.5 to 4 mm. Further, each suction hole 103 is continuous in the back surface side of the outer peripheral surface of the suction tube 10, slightly on the side surface and a plurality of side surfaces, that is, so as to draw a spiral in the circumferential direction (spiral movement in the longitudinal direction). (See FIGS. 1 and 2 in particular).

  The connecting part 11 corresponds to a “connecting part” according to the present invention, and is a part that connects the suction pipe 10 and a suction means described later. The connection component 11 is formed of a resin such as polypropylene, for example, and includes a connection end 110 on the suction tube 10 side and a connection end 111 on the suction means side, and a plurality of suction tube side connection ends 110 join together. It is formed in a substantially Y shape that communicates with one suction means side connection end 111. A plurality of protrusions 112 for preventing removal protrude from the suction tube side connection end 110 and the suction means side connection end 111. Note that the connection component 11 is not limited to a substantially Y-shape, and is, for example, a substantially T-shape such that the suction tube side connection end portion 110 joins and communicates with the suction means side connection end portion 111. Any shape is acceptable.

  The binding component 12 corresponds to a “binding portion” according to the present invention, and is a component that partially binds the suction tubes 10 together. The binding component 12 is an annular member formed of silicone rubber similar to the suction pipe 10, for example. The binding component 12 partially bundles the suction pipes 10 at a plurality of locations, and forms a separation space E for fitting to a mouthpiece 2 described later between the plurality of binding locations 102.

Moreover, the binding component 12 has elasticity, and the size of the ring changes freely. When the size of the ring is changed to a small diameter, the bundling component 12 is bundled with a force that does not crush the conduit of the suction pipe 10, while the size of the ring is changed to a large diameter. The suction tube 10 can be moved along the longitudinal direction of the suction tube 10 between the both end portions 100 of the suction tube 10 and the farthest bent region 101. In the separation space E formed between the binding portions 102, the separation distance between the suction pipes 10 changes freely according to the movement of the binding component 12.
Further, the binding component 12 is formed by curving the farthest bent region 101 so as to be substantially annular by binding the suction tube 10, and moving along the longitudinal direction of the suction tube 10, thereby moving the farthest bent region 101. The size of the ring 101 is changed freely.

  FIG. 2 is a perspective view showing a state in which the mouthpiece suction tool 1 according to the present invention is attached to the endoscope mouthpiece 2. In FIG. 2, 2 is an endoscope mouthpiece. The endoscope mouthpiece 2 is made of, for example, acrylonitrile, butadiene (Butadiene), styrene (Styrene) copolymer synthetic resin (hereinafter referred to as “ABS resin”), and the main body has a substantially cylindrical shape. ing. The endoscope mouthpiece 2 includes an insertion guide portion 20, an oral cavity outer buttock 21, an oral cavity inner buttock 22, and an occlusal recess 23.

  The insertion guide portion 20 is formed on the inner peripheral side of the cylinder. When the mouthpiece body is bitten by the examinee, the insertion guide portion 20 penetrates from the outside of the mouthpiece 2 to the inside of the mouth and points the endoscope (not shown) into the mouth. I will guide you.

  The oral cavity outer buttock 21 protrudes in a radial manner along the opening edge of the insertion guide part 20 on the outer oral cavity, and holds the mouthpiece body bitten by the examinee at the lip position.

  The oral cavity inner buttock 22 protrudes in a radial shape along the opening edge inside the oral cavity of the insertion guide part 20, and forms an occlusal recess 23 with the aforementioned oral cavity outer buttock 21. The occlusal recess 23 is a recess that can accommodate a part of the teeth or a part of the gums of the subject's dentition, and is also a place where the suction tube 10 is fitted. Since the mouthpiece main body has a sufficient depth, the occlusal recess 23 can have a sufficient avoidance space so that, for example, the teeth to be engaged and the suction tube 10 do not overlap.

  In the suction tool 1, the separation distance E is adjusted according to the movement of the binding component 12, and the adjusted separation space E is fitted into the mouthpiece body. At this time, the separation distance of the separation space E is adjusted to be larger than the oral cavity inner buttock 22 but smaller than the oral cavity outer buttock 21. Thereafter, in the state where the suction tool 1 is fitted in the mouthpiece body, the separation distance of the separation space E is readjusted and fastened to the outer periphery of the mouthpiece body. At this time, the separation distance of the separation space E is readjusted so as to have a smaller diameter than the oral cavity outer buttock 21 and the oral cavity inner buttock 22.

  FIG. 3 is a view seen from the outside of the oral cavity, showing a state where the mouthpiece suction tool 1 according to the present invention is inserted into the oral cavity of the subject. As shown in FIG. 3, the suction tool 1 is continuously inserted from the farthest bending region 101 side into the subject's lip L, and the teeth of the subject are inserted into the occlusal recess 23 of the endoscope mouthpiece 2. Part of the row or part of the gum is accommodated. At this time, in the suction tool 1, the part of the connection part 11 that is hung from the both ends 100 protrudes from the oral cavity of the person to be inspected, and the suction means is connected to the suction means side connection end 111 of the connection part 11. . Here, the suction means corresponds to a suction machine including a suction pump and a power feeding unit.

  FIG. 4 is a view of the mouthpiece suction tool 1 according to the present invention as seen from the inside of the oral cavity, showing a state where the mouthpiece suction tool 1 is inserted into the oral cavity of the subject. As shown in FIG. 4, in the suction tool 1, the farthest bending region 101 side is inserted into the inspected person's oral cavity, while the portions from both ends 100 to the connection part 11 are outside the inspected person's oral cavity. It's popping out. At this time, the farthest bending region 101 abuts on the oral cavity wall W and the suction tool 1 is bent and deformed to the throat side. The plurality of suction holes 103 drilled in the farthest bending region 101 are drilled at a location where at least a part does not come into contact with the oral cavity wall W, that is, on the side opposite to the oral cavity wall W. Further, as described above, the plurality of suction holes 103 are continuously formed so as to draw a spiral in the circumferential direction of the suction tube 10 (so as to spirally move in the longitudinal direction). Compared to the case where the suction hole 103 is continuously drilled only on the side surface side, the farthest bending region 101 is less likely to be bent in a substantially square shape and is curved so that it flows naturally. Further, it is difficult to cause a situation in which the stress is concentrated at a portion bent in a substantially square shape and the suction tube 10 is torn off. In addition, even when the subject moves his / her head to move the storage location of saliva, etc., a plurality of suction holes continuously drilled so as to draw a spiral (so as to move spirally in the longitudinal direction) Any of the holes 103 catches the storage location. Further, since the plurality of suction holes 103 are curved, the suction target can be captured by a “surface” wider than the “point”.
