Description

Technical Field

[0001] The invention belongs to the technical field of gastroscopy auxiliary equipment, and in particular relates to an oral auxiliary device for gastroscopy of children. Background Art

[0002] Gastroscopy is a medical examination method, and also refers to the instrument used for this examination. It uses a thin, soft tube to extend into the stomach, so that the doctor can directly observe the lesions of the esophagus, stomach and duodenum, especially the tiny lesions. Gastroscopy can directly observe the true condition of the examined area, and can further clarify the diagnosis by performing pathological biopsy and cytological examination on the suspected lesions. It is the preferred examination method for upper gastrointestinal tract lesions. The anatomical structure of the mouth, throat and esophagus of children is more delicate, and children's cooperation is often lower. Therefore, there are higher operational difficulties and risks in gastroscopy for children. However, traditional oral aids are mostly fixed in size and cannot adapt to the size of the mouths of children of different ages, which may increase the pain of children and the risk of examination due to inappropriate size during the examination.

[0003] The patent with publication number CN212037462U discloses a bite mouth for gastroscopy of children with adjustable size, including a baffle, fixed blocks are fixedly connected to both sides of the top of the baffle, a threaded rod is threadedly connected to one side of the fixed block, a turntable is fixedly connected to one end of the threaded rod, a push plate is rotatably connected to the other end of the threaded rod, a tooth groove is provided on the side of the push plate away from the threaded rod, a through hole is provided at the center of the top of the baffle, a slide groove corresponding to the push plate is provided on the baffle, and the push plate is slidably connected to the slide groove, a first rope seat is fixedly connected to one side of the baffle, and a first elastic rope is fixedly connected to the top of the first rope seat , one end of the first elastic rope away from the first rope seat is fixedly connected with the first buckle; when in use, the side of the baffle with the threaded rod is placed in the child's mouth, and the turntables on the upper and lower sides are rotated through the through-mouth, so that the threaded rod rotates to push the push plate close to the teeth, and the tooth grooves on the push plate are used to limit the teeth to ensure that the push plate will not fall off the teeth. Through this arrangement, the push plate is used to press against the upper and lower jaws to ensure that the teeth will not touch the gastroscope. Moreover, since it is controlled by the threaded rod, the size can be adjusted according to the size of the child's mouth, avoiding the situation where gastroscopy cannot be performed due to the mismatch of the bite device.

[0004] In the above technical solution, the upper and lower jaws of the child are fixed by a push plate. Since the push plate is made of hard material, it is not comfortable. When the child's cooperation is low, he will struggle. At this time, the push plate is easy to collide with the inner wall of the child's mouth and teeth, which has poor safety. Moreover, since the push plate is in a plate-like structure, it does not fit the inner wall of the child's mouth and has poor comfort. Summary of the invention

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features limited to "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] It should be noted that the oral aid for gastroscopy for children provided by the present invention is suitable for patients who need to undergo gastroscopy, especially for children. Example 1

[0032] This embodiment provides an oral aid for gastroscopy in children, such as Figure 1-18 As shown, it includes a fixing plate 1, an expansion airbag 2, an adjustment component 3 and a tongue depressor 4.

[0033] The tongue depressor 4 is an arc-shaped structure, and is used to press and fix the patient's tongue to facilitate the passage of the gastroscope.

[0034] like Figure 6 and 7 As shown, the fixed plate 1 is a circular ring structure, which is fixedly arranged at one end of the tongue depressor 4 located outside the patient's oral cavity. Specifically, the fixed plate 1 is integrally connected with the tongue depressor 4. When in use, the tongue depressor 4 is placed on the upper end of the patient's tongue, and the fixed plate 1 is placed outside the patient's oral cavity, so as to limit the expansion airbag 2 in the central through hole of the fixed plate 1.

[0035] like Figure 4As shown, the expansion balloon 2 includes an outer ring cloth, an inner ring cloth, and an annular connecting cloth connecting the outer ring cloth and the inner ring cloth into a cylindrical structure, so that an annular inflation cavity is formed inside the expansion balloon 2; wherein the opening size of the expansion balloon 2 is the inner diameter size of the central through hole formed by the inner ring cloth. When in use, the expansion balloon 2 passes through the center of the fixed plate 1 and enters the patient's oral cavity to open the patient's oral cavity, and then the gastroscope passes through the central through hole formed by the inner ring cloth to examine the patient.

[0036] Among them, Figure 5 As shown, an elastic band 21 is provided in the annular inflation cavity and between the outer circle cloth and the inner circle cloth. One end of the elastic band 21 is connected to the outer circle cloth, and the other end is connected to the inner circle cloth.

[0037] During the process of inflating the expansion airbag 2, the expansion airbag 2 is deformed; at the beginning, the outer circle of the expansion airbag 2 is propped up first, while the inner circle of the expansion airbag 2 is not propped up and collapses; when the air is sufficiently inflated, the inner circle of the expansion airbag 2 expands, so that the inner diameter of the central through hole formed by the inner circle of the expansion airbag 2 becomes larger; Based on this, when the expansion balloon 2 is not inflated, the outer circle of cloth can drive the inner circle of cloth to expand outward through the elastic band 21 to prop up the inner circle of cloth, thereby preventing the inner circle of cloth from collapsing due to insufficient inflation and blocking the medical staff's field of vision.

[0038] like Figure 4 and 10 As shown, the adjustment assembly 3 includes a control disk 31 and a plurality of adjustment units 32 arranged circumferentially on the fixed disk 1. The plurality of adjustment units 32 arranged circumferentially are located between the fixed disk 1 and the control disk 31.

[0039] Specifically, Fig.12 As shown, the adjustment unit 32 includes a connection block 32a, a support rod 32b and a rotation rod 32c. One end of the connection block 32a is connected to the support rod 32b, and the other end is rotatably connected to the rotation rod 32c.

[0040] The movable end of the support rod 32 b penetrates through the sealing opening of the expansion airbag 2 and enters the annular inflation cavity to support the opening of the expansion airbag 2 .

[0041] The connecting block 32a is provided with a third connecting hole so as to be rotatably connected with the rotating rod 32c. Specifically, the connecting block 32a is a triangular petal-shaped structure. When in use, the sides of each connecting block 32a are in contact and closely arranged, so that the supporting rods 32b connected to the connecting block 32a are arranged at equal intervals on the circumference at the port of the expansion airbag 2, and an opening is formed in the center of each connecting block 32a after being arranged.

[0042] In order to facilitate the sliding of the rotating rod 32c, as shown in FIG. Figure 7As shown, a plurality of limiting grooves 11 are provided on the fixed plate 1, and as shown in FIG. Fig. 9 As shown, a plurality of sliding holes 31a are provided on the control disk 31; wherein the limiting groove 11 and the sliding hole 31a have the same shape, and the two are arranged to overlap so that the rotating rod 32c can rotate.

[0043] It should be noted that the number of the limiting grooves 11 and the sliding holes 31 a corresponds to the number of the connecting blocks 32 a , that is, each adjusting unit 32 corresponds to one limiting groove 11 and one sliding hole 31 a .

[0044] In practical applications, the limiting groove 11 and the sliding hole 31a are both long strip structures, and the longer the limiting groove 11 and the sliding hole 31a are, the larger the linear movement range of the rotating rod 32c is, and thus the larger the opening adjustment range of the expansion airbag 2 is.

[0045] A folding handle 33 is provided on the control disk 31; when in use, the medical staff pulls out the folding handle 33 and holds it tightly, and then rotates the control disk 31, and the control disk 31 drives the rotating rod 32c to rotate through the sliding hole 31a, and then the rotating rod 32c drives the connecting block 32a to move toward the center of the fixed disk 1 through the third connecting hole. At this time, the inner diameter of the through hole of the inner circle cloth of the expansion airbag 2 becomes smaller, that is, the opening of the expansion airbag 2 becomes smaller; If the control disk 31 is rotated in the opposite direction, the control disk 31 drives the rotating rod 32c to rotate through the sliding hole 31a, and then the rotating rod 32c drives the connecting block 32a to move toward the outside of the fixed disk 1 through the third connecting hole 32a-1. At this time, the inner diameter of the through hole of the inner circle cloth of the expansion airbag 2 becomes larger, that is, the opening of the expansion airbag 2 becomes larger, thereby realizing the opening adjustment of the expansion airbag 2.

[0046] When using, Fig.16 As shown, it is a state diagram in which the medical staff rotates the control plate 31 by folding the handle 33 to make the rotating rod 32a move to the inner side of the sliding hole 31a. The rotating rod 32a is located at the innermost side of the sliding hole 31a. At this time, the opening of the expansion airbag 2 is the smallest; like Fig.17 As shown, the medical staff rotates the control plate 31 through the folding handle 33, so that the rotating rod 32a moves from the innermost side of the sliding hole 31a to the middle part. At this time, the opening of the expansion airbag 2 is slightly expanded; like Fig.18 As shown, the medical staff continues to rotate the control disk 31 through the folding handle 33, so that the rotating rod 32a moves from the middle of the sliding hole 31a to its outermost end, and the opening of the expansion airbag 2 continues to be expanded by the folding unit 32. At this time, the opening of the expansion airbag 2 is in the maximum state.

[0047] It should be noted that the embodiment of the present invention does not limit the number of the connecting blocks 32 a . For example, the embodiment of the present invention takes the number of the adjusting units 32 as 6 as an example.

[0048] In order to facilitate the inflation of the expansion balloon 2, as Figure 3 and 7 As shown, an inflation channel 12 is provided on the fixed plate 1, one end of the inflation channel 12 is sealedly connected to the inflation port of the expansion airbag 2, and the other end is connected to the telescopic inflation tube 7; the end of the telescopic inflation tube 7 away from the expansion airbag 2 passes through the control plate 31 and is connected to the external inflation device. It should be noted that the inflation device in the embodiment of the present invention is a prior art, and the embodiment of the present invention does not improve it.

[0049] It should be noted that during the overall inflation process of the expansion balloon 2 provided in the embodiment of the present invention, due to the supporting effect of the support rod 32b, the opening shape of the expansion balloon 2 remains unchanged. After expansion, the expansion balloon 2 is stuck in the central through hole of the fixed plate 1, and then the outer edge of the expansion balloon 2 expands and opens the patient's mouth to facilitate subsequent gastroscopy.

[0050] The operating method of the oral auxiliary device for gastroscopy in children provided by the embodiment of the present invention includes: Step 1: placing one end provided with the expansion balloon 21 in the patient's mouth; Specifically, one end of the tongue depressor 4 provided with the expansion airbag 21 is placed in the patient's mouth to fix the patient's tongue; Step 2: driving the adjustment unit 32 to rotate by the control disk 3 until the size of the opening formed by the adjustment unit 32 matches the size of the patient's oral cavity; Specifically, the medical staff rotates the folding handle 33 on the control disk 3, and drives the control disk 3 to rotate through the folding handle 33, and then the control disk 3 drives each adjustment unit 32 to move to the outside of the fixed disk 1 through the sliding hole 31a, so that the opening of the expansion airbag 2 becomes larger; Or, the folding handle 33 is rotated to drive the control disk 3 to rotate, and then the control disk 3 drives the adjustment unit 32 to move toward the inner side of the fixed disk 1 through the sliding hole 31a, so that the opening of the expansion balloon 2 becomes smaller until the opening size of the expansion balloon 2 matches the width of the patient's esophagus; Step 3: Connect the inflation device to the inflation port provided on the control panel 31 to inflate the expansion balloon 2 until the outer ring cloth of the expansion balloon 2 opens and fixes the patient's oral cavity; Step 4: Insert the gastroscope into the patient's body through the opening of the dilation balloon 2 to start gastroscopy. Example 2

[0051] Based on Example 1, different from Example 1, in order to prevent the patient from choking during the examination, as shown in FIG. Figure 3 and 5 As shown, the tongue depressor 4 and the fixed plate 1 provided in the embodiment of the present invention are provided with a drainage unit for drawing out the saliva in the oral cavity.

[0052] The drainage unit comprises a tongue depressor 4 and a drainage channel 5 arranged in the fixed disk, and a telescopic drainage hose 6. The tongue depressor 4 is connected to the drainage channel 5 in the fixed disk.

[0053] Specifically, one end of the telescopic drainage hose 6 is connected to the outlet of the drainage channel 5 of the fixed disk 1, and the other end passes through the control disk 31 and is connected to the external negative pressure suction device to suck out the saliva in the patient's mouth. It should be noted that the negative pressure suction device in the embodiment of the present invention is a prior art, and the embodiment of the present invention does not improve it. Example 3

[0054] Based on Example 1, what is different from Examples 1 and 2 is that Fig.19 and 20 As shown, a limiting unit 34 is provided at the end of the connecting rod 32c provided in the embodiment of the present invention.

[0055] It should be noted that the embodiment of the present invention does not limit the specific structure of the limiting unit 34. For example, the limiting unit 34 is a limiting piece or a limiting bolt fixedly arranged at the end of the connecting rod 32c. The embodiment of the present invention is described by taking the limiting unit 34 as a limiting bolt as an example.

[0056] Specifically, a threaded hole is provided at one end of the connecting rod 32c, and after the end of the connecting rod 32c with the threaded hole passes through the sliding hole 31a, it is connected to the limiting bolt, so that the limiting bolt can prevent the adjustment unit 32 from being separated from the control panel 31.

[0057] Application examples: The patient, Mr. Liu, a 10-year-old male, came to the hospital for treatment due to "severe upper abdominal pain for 3 days". After physical examination by the attending physician, the abdomen was found to be soft, without abdominal muscle tension, upper abdominal tenderness, and no rebound pain. Therefore, he was arranged to undergo an electronic gastroduodenoscope to assist in further diagnosis and treatment.

[0058] Step 1: The medical staff places the end of the tongue depressor 4 provided with the expansion airbag 21 in the patient's mouth; Step 2: The control disk 31 is driven to rotate by the folding handle 33, and then the control disk 3 drives the rotating block 32a and the support rod 32b to move linearly through the rotating rod 32c until the size of the opening formed by the adjustment unit 32 matches the size of the patient's oral cavity; In this step, the medical staff rotates the rotary control disk 3, and the control disk 3 rotates clockwise, driving the adjustment unit 32 to move outward, so that the opening of the expansion balloon 2 becomes larger; Or, the folding handle 33 is rotated to drive the control disk 3 to rotate, and then the control disk 3 drives the adjustment unit 32 to move toward the inner side of the fixed disk 1 through the sliding hole 31a, so that the opening of the expansion balloon 2 becomes smaller until the opening size of the expansion balloon 2 matches the width of the patient's esophagus; Step 3: Connect the inflation device to the inflation port of the telescopic inflation tube 7 provided on the control panel 31 to inflate the expansion balloon 2 until the expansion balloon 2 opens and fixes the patient's oral cavity; Step 4: Connect the negative pressure suction device to the negative pressure suction port of the telescopic drainage hose 6 on the control panel 31, and suck the saliva in the patient's mouth out of the body through the drainage channel 5 and the telescopic drainage hose 6 to prevent the patient from choking; Step 5: Insert the gastroscope into the patient's body through the opening of the dilation balloon 2 to start gastroscopy.
