DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0017] In view of the problems existing in the prior art, an embodiment of the present invention provides an intelligent esophageal directional applicator, such as Figure 1 , Figure 2 and Figure 3 As shown, the intelligent esophageal directional applicator includes an outer tube 1, and the first end of the outer tube 1 (which can be understood as the right end) is fixedly plugged into the side plate (which can be understood as the left side plate) of the support box 4. The second end of the outer tube 1 (which can be understood as the left end) is connected to the outer cover body 2, and the bottom of the outer cover body 2 is provided with a monitor 3. The inner tube 5 is movably arranged in the outer tube 1, and the first end of the inner tube 5 (which can be understood as the left end) extends into the outer tube 1, and the first end of the inner tube 5 is connected to the inner cover body 9, and the inner cover body 9 is movably arranged in the outer cover body 2. It is worth noting that the outer side wall of the inner cover body 9 and the inner side wall of the outer cover body 2 are slidably arranged, and it can be understood that the gap between the two can be ignored, so that the drug liquid can be prevented from escaping into the outer cover body 2 as much as possible, thereby ensuring that the drug liquid can be sprayed to the target position more. The second end (which can be understood as the right end) of the inner tube 5 extends into the support box 4, and the second end of the inner tube 5 is connected to a rotation drive mechanism 6, and the support box 4 is provided with a drug feeding mechanism 7 for conveying liquid medicine into the inner tube 5, and the outer cover body 2 is provided with a plurality of first drug coating holes 8, and the inner cover body 9 is provided with a plurality of second drug coating holes 10, and the first drug coating holes 8 and the second drug coating holes 10 are arranged correspondingly.

[0018] During operation, the monitor 3 monitors the spray target position in real time and controls the intelligent start and stop of the rotary drive mechanism 6. When the second coating hole 10 is not facing the spray target position, the rotary drive mechanism 6 will be controlled to start, and the inner cover body 9 will be rotated through the inner tube 5, and the second coating hole 10 will be rotated to the spray target position through the inner cover body 9. At this time, the liquid medicine will enter the inner cover body 9 through the medicine feeding mechanism 7 and the inner tube 5, and will be sprayed to the target position through the second coating hole 10 and the first coating hole 8 in turn. In one example, the target position can be understood as the injured area. It should be noted that when the monitor 3 detects that the second coating hole 10 moves to the target position, the rotary drive mechanism 6 is controlled to stop working.

[0019] In one embodiment, Figure 1 He Ru Figure 3 As shown, the outer cover body 2 and the inner cover body 9 both have a first surface (which can be understood as the front), a second surface (which can be understood as the right surface), a third surface (which can be understood as the back) and a fourth surface (which can be understood as the left surface), and the first surface, the second surface, the third surface and the fourth surface surround the outer cover body 2 and the inner cover body 9, and a plurality of the first coating holes 8 are distributed on the first surface, the second surface, the third surface and the fourth surface. It should be understood that when working, in one example, the outer cover body 2 is in a stationary state. A plurality of second coating holes 10 are distributed on the first surface. When working, the inner cover body 9 will rotate relative to the outer cover body 2 so that the second coating holes 10 are facing the target position. Specifically, during operation, when the first surface of the outer cover body 2 is aligned with the first surface of the inner cover body 9, the medicine liquid will be sprayed from the first coating hole 8 and the second coating hole 10 to the target position. The aperture of the first coating hole 8 is larger than the aperture of the second coating hole 10. This arrangement allows the medicine liquid to be sprayed from the second coating hole 10 to the target position more conveniently.

[0020] In one embodiment, Figure 1 As shown, the rotary drive mechanism 6 includes a drive motor 63, which is fixedly arranged in the support box 4, and the drive end of the drive motor 63 is connected to a rotating rod 62, and the free end (which can be understood as the left end) of the rotating rod 62 is fixedly connected to a rotating cylinder 61. The rotating cylinder 61 and the rotating rod 62 are movably arranged in the support box 4, and the inner tube 5 is fixedly inserted in the rotating cylinder 61, wherein the inner side wall of the rotating cylinder 61 is tightly fitted with the outer side wall of the inner tube 5, so that the liquid medicine can be prevented from escaping from the gap between the rotating cylinder 61 and the inner tube 5 into the support box 4. And the inner cavity of the rotating cylinder 61 is connected with the inner cavity of the inner tube 5.

[0021] In one embodiment, Figure 1 , Figure 4 and Figure 5As shown, the medicine feeding mechanism 7 includes an annular groove 71, and the annular groove 71 is provided on the rotating cylinder 61, specifically, on the outer ring wall of the rotating cylinder 61. The rotating cylinder 61 is movably sleeved with a support ring 72, and the support ring 72 is movably provided in the annular groove 71, so that the rotating cylinder 61 can rotate relative to the support ring 72. A liquid storage cavity 74 is provided inside the support ring 72, and the liquid storage cavity 74 is an annular structure. A medicine feeding pipe 73 is fixedly connected to the support ring 72, and one end of the medicine feeding pipe 73 extends into the liquid storage cavity 74, and the other end of the medicine feeding pipe 73 is connected to a medicine tank source (not shown), and the medicine tank source is used to provide liquid medicine, and the medicine tank source is connected to a booster pump. The support ring 72 is provided with M first through holes 75, and the rotating cylinder 61 is provided with N second through holes 76. The first through holes 75 and the second through holes 76 are used for the liquid storage cavity 74 to communicate with the inner cavity of the rotating cylinder 61. M is a positive integer greater than or equal to 2, and N is a positive integer greater than or equal to 2. It is worth noting that the number of the first through holes 75 and the second through holes 76 are matched. The number of the first through holes 75 and the second through holes 76 can be set to two, three, four or more.

[0022] During operation, when the second coating hole 10 is facing the target position, the medicine tank source inputs the medicine liquid into the medicine inlet pipe 73 through the booster pump, and the medicine liquid entering the medicine inlet pipe 73 will be sprayed to the target position through the liquid storage cavity 74, the first through hole 75, the second through hole 76, the rotating cylinder 61, the inner tube 5, the inner cover body 9, the second coating hole 10 and the first coating hole 8.

[0023] In one embodiment, Figure 6 and Figure 7 As shown, the intelligent esophageal directional applicator also includes a leak-proof mechanism 11, which is arranged inside the inner cover body 9. During operation, when the first surface of the outer cover body 2 is not aligned with the first surface of the inner cover body 9, the leak-proof mechanism 11 is abutted by the inner side wall of the outer cover body 2 to seal the second coating hole 10, thereby preventing the liquid medicine from entering the first coating hole 8 from the inner cover body 9 through the second coating hole 10. When the first surface of the outer cover body 2 is aligned with the first surface of the inner cover body 9, the leak-proof mechanism 11 loses the abutment with the inner side wall of the outer cover body 2, thereby losing the blockage of the second coating hole 10, so that the liquid medicine can be sprayed onto the target site through the second coating hole 10 and the first coating hole 8.

[0024] In one embodiment, Figure 7As shown, the leak-proof mechanism 11 includes a leak-proof column 111, which is movably inserted in the second coating hole 10, and the leak-proof column 111 is slidably connected to the hole wall of the second coating hole 10, and a fourth through hole 117 is provided on the leak-proof column 111, and the fourth through hole 117 is communicated with the inner cavity of the inner cover body 9, and a third through hole 112 connected to the fourth through hole 117 is provided on the leak-proof column 111. During operation, when the first surface of the outer cover body 2 is aligned with the first surface of the inner cover body 9, the leak-proof column 111 will move with the third through hole 112 into the first coating hole 8, so that the medicine can enter the first coating hole 8 through the third through hole 112, and be sprayed to the target position through the first coating hole 8.

[0025] In one embodiment, Figure 7 As shown, the leakage-proof mechanism 11 also includes a connecting column 113, the connecting column 113 is fixedly arranged on the leakage-proof column 111, the free end of the connecting column 113 is fixedly connected to the vertical plate 114, the vertical plate 114 is fixedly connected with a guide limit assembly 115, the free end of the guide limit assembly 115 is fixedly connected to a vertical rod 116, and the vertical rod 116 is fixedly arranged on the inner side wall of the inner cover body 9, wherein there is a gap between the vertical plate 114 and the leakage-proof column 111, and the size of the gap is between 0.1cm-3cm.

[0026] During operation, when the first surface of the outer cover body 2 and the first surface of the inner cover body 9 are not aligned, the right end of the leakage-proof column 111 conflicts with the inner side wall of the outer cover body 2. At this time, the third through hole 112 shrinks into the second coating hole 10. When the first surface of the outer cover body 2 and the first surface of the inner cover body 9 are aligned, the first coating hole 8 and the second coating hole 10 are also aligned. At this time, under the push of the guide limit assembly 115, the third through hole 112 will be moved to the right by the leakage-proof column 111 and extend into the first coating hole 8. At this time, the liquid medicine will move from the third through hole 112 to the first coating hole 8 and be sprayed from the first coating hole 8 to the target position.

[0027] In one embodiment, Figure 7As shown, the guide limit assembly 115 includes a guide limit rod 1151, a guide limit cylinder 1152 and a guide limit spring 1153. The guide limit rod 1151 is movably inserted in the guide limit cylinder 1152, and the guide limit spring 1153 is wound around the outside of the guide limit rod 1151, and the two ends of the guide limit spring 1153 are respectively fixedly connected to the side wall of the guide limit rod 1151 and the outer side wall of the guide limit cylinder 1152, the guide limit rod 1151 is interconnected with the vertical plate 114, and the guide limit cylinder 1152 is interconnected with the vertical rod 116. The setting of the guide limit assembly 115 can not only play the role of guiding and supporting the movement of the leakage-proof column 111, so that the leakage-proof column 111 can only move in the horizontal direction, but also provide a driving force for the rightward movement of the leakage-proof column 111, and can push the leakage-proof column 111 with the third through hole 112 to move into the first coating hole 8.

[0028] As the device is used, part of the liquid medicine will still enter the outer cover 2. In order to prevent the liquid medicine from accumulating in the outer cover 2, in one embodiment, Figure 8 and Fig. 9 As shown, the outer cover body 2 includes a cover body 21, a mounting hole 22 is provided at the bottom of the cover body 21, the mounting hole 22 is communicated with the inner cavity of the cover body 21, a mounting plate 23 is installed in the mounting hole 22, the mounting plate 23 is used to block the mounting hole 22, the monitor 3 is connected to the mounting plate 23, a plurality of positioning rods 24 are fixedly connected to the upper end surface of the mounting plate 23, the positioning rods 24 are movably inserted in the positioning holes 25, the positioning holes 25 are arranged to match the number of the positioning rods 24, and the positioning holes 25 are provided on the cover body 21. In this embodiment, the structure of the outer cover body 2 is reasonably designed, and the drug liquid accumulated in the outer cover body 2 can be released by disassembling the cover body 21 and the mounting plate 23, thereby preventing the drug liquid from accumulating in the outer cover body 2.

[0029] In order to intelligently realize the control of the disassembly and installation of the cover body 21 and the mounting plate 23, in one embodiment, as shown in FIG. Figure 8 , Fig. 9 and Fig.10As shown, the intelligent esophageal directional applicator also includes a mounting drive mechanism 12, and the mounting drive mechanism 12 is used to drive the mounting plate 23 to move in the vertical direction. The mounting drive mechanism 12 includes a rotating shaft 122, and the rotating shaft 122 is connected to the mounting plate 23. The upper end of the rotating shaft 122 is connected to a driving soft rod 121, and the setting of the rotating shaft 122 is used for the driving soft rod 121 to rotate relative to the mounting plate 23. The driving soft rod 121 is movably inserted in the inner cover body 9 and the inner tube 5, and the driving soft rod 121 is movably inserted in the side wall of the rotating cylinder 61, and the end of the driving soft rod 121 away from the rotating shaft 122 is connected to the driving end of the driving cylinder 123, and the driving cylinder 123 is fixedly arranged in the supporting box 4.

[0030] During operation, after each spraying of the liquid medicine, as the equipment is taken out, the monitor 3 will control the drive cylinder 123 to start, and the drive cylinder 123 will push the mounting plate 23 downward through the drive soft rod 121, and disengage from the mounting hole 22, thereby releasing the liquid medicine accumulated in the cover body 21.
