[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Next, refer to Figures 1-5 to understand the first aspect embodiments of the present invention.

[0035] This embodiment discloses an anorectal drug delivery device, including: a housing 200, a driving mechanism 300, and a drug delivery pulley 400. A medicine storage bin 250 is formed inside the housing 200, and the housing 200 is provided with at least one medicine outlet; the driving mechanism 300 includes a first roller 310 and a driver 320, and the driver 320 is used to drive the first roller 310 to rotate; the drug delivery pulley 400 is wound around the outside of the housing 200, and at least part of the drug delivery pulley 400 is sleeved on the first roller 310; the outlet of the medicine outlet extends to the outer side surface 410 of the drug delivery pulley 400, and the medicine storage bin 250 is provided with a drug delivery component 600.

[0036] As in the foregoing example, the length direction of the drug delivery pulley 400 and the length direction of the housing 200 are both arranged along the first direction. The outlet of the medicine outlet extends to the outer side surface 410 of the drug delivery pulley 400 so that the medicine in the medicine storage bin 250 can be smoothly released onto the outer side surface 410 of the drug delivery pulley 400. After the drug delivery pulley 400 is inserted into the patient's anus, the function of anorectal drug delivery can be achieved. In this embodiment, the drug delivery component 600 discharges the medicine in the medicine storage bin 250 from the medicine outlet.

[0037] The foregoing example is only a possible implementation manner and does not limit the present utility model. Specifically, it can be of different structures.

[0038] For example, refer to Figures 1-2 the example shown for understanding.

[0039] As Figure 1 shown, the anorectal drug delivery device in this example includes a handle 100. The handle 100 is a columnar rod structure for the user to hold. One end of the handle 100 is provided with a housing 200. Specifically, the housing 200 and the handle 100 are of an integral structure. The housing 200 is a long strip-shaped hollow shell. The housing 200 includes two arc-shaped housings 210 and two flat plate-shaped housings 220. The housing 200 has a flat end 230 and a round head end 240 at both ends in Figure 1 the first direction shown. The end where the housing 200 is connected to the handle 100 as an integral structure is the flat end 230, and the other end is the round head end 240. The chamber formed inside the housing 200 is the medicine storage bin 250.

[0040] Further refer to Figure 2 for understanding. A partition 251 is further provided in the medicine storage bin 250. The partition 251 divides the medicine storage bin 250 into a first chamber 252 and a second chamber 253 (the first chamber 252 and the second chamber 253 can be combined with the subsequent Figure 7(Understand the structure shown). Among them, the first chamber 252 is used to store drugs, and the second chamber 253 is used to arrange the driving mechanism 300. The housing 200 is provided with two first through holes 221 on one side close to the flat end 230, and the two first through holes 221 are respectively arranged in the two flat housing 220; the medicine outlet is the second through hole 222 opened by the housing 200 on one side close to the round head end 240. In the illustrated structure, a guiding cover 500 extends from the edge of the second through hole 222. Therefore, in the illustrated structure, the guiding cover 500 blocks the second through hole 222. Those skilled in the art can understand the position of the second through hole in combination with the existing drawings. The specific structure of the guiding cover 500 will be described in detail in the following content.

[0041] In this example, the length direction of the housing 200 is the first direction, the direction of arranging the two arc-shaped housings 210 is the second direction, and the first direction is perpendicular to the second direction. Different angles may also exist in different situations. Therefore, the situation of this example should not limit the present invention.

[0042] The driving mechanism 300 is arranged in the second chamber 253. Refer to Figure 2 the driving mechanism 300 shown is provided with a first roller 310. The specific structure can be understood by referring to the subsequent embodiments. Here, continue to describe Figures 1-2 the structure shown. As described above, the first roller 310 is wound with a medicine delivery belt pulley 400; the round head end 240 is provided with a second roller 241, and a second fixing strip 242 is arranged between the second roller 241 and the round head end 240. The rotation center of the first roller 310 is rotatably connected to the end of the second fixing strip 242. Specifically, the medicine delivery belt pulley 400 is wound around the first roller 310 and the second roller 241 respectively. The medicine delivery belt pulley 400 passes through the two first through holes 221 and passes through the upper area of the second through hole 222.

[0043] It can be understood that since the anorectal administration is mostly gel drugs, in the example, the gel drugs are stored in the first chamber 252. When the driving mechanism 300 is started, the gel drugs are pressed onto the medicine delivery belt pulley 400 by the first roller 310. As the medicine delivery belt pulley 400 rotates, the gel drugs pass through the two first through holes 221 and are finally released through the second through hole 222. The medicine delivery belt pulley 400 enables the gel drugs to be evenly smeared on the surface of the patient's anorectal area.

[0044] During use, the user needs to hold the handle 100 by hand and slowly push the second fixing strip 242 and the medicine delivery pulley 400 into the rectum. In some cases, a lubricant can be applied to the medicine delivery pulley 400. Specifically, during the pushing process, the user can activate the driving mechanism 300, and the driving mechanism 300 can also be externally connected with a switch for activation. More specifically, the switch can be any existing switch. The driving mechanism 300 will start to drive the medicine delivery pulley 400, so that the medicine strip is pushed from the first chamber 252 through the first through hole 221 onto the medicine delivery pulley 400, and then continues to be conveyed to the medicine delivery pulley 400 through the second through hole 222. And because the medicine delivery pulley 400 is moving in the rectal direction, the user can use the movement of the medicine delivery pulley 400 to smoothly insert the medicine delivery pulley 400 and the second fixing strip 242 into the patient's anus. It can be seen that the smooth movement of the medicine delivery pulley 400 cooperates with the insertion action, reducing the friction with the rectum / anus and greatly reducing the discomfort that the patient may feel during use, thus alleviating the discomfort of the patient.

[0045] Compared with other drug delivery methods, the medicine delivery pulley 400 plays a role of smearing in the rectum. Specifically, after the first drug delivery, the anorectal drug delivery device in this example is rotated 180° along the central axis of the handle 100 for the second drug delivery, so that the medicine delivery pulley 400 can push the rectal valves in the rectum in two opposite directions. The medicine delivery pulley 400 evenly smears the drug on one side of the rectal valve during the first drug delivery, and then by rotating the device 180°, it can also evenly smear the other side of the rectal valve during the second drug delivery. This two-way smearing method ensures that the drug can fully cover every surface of the rectal wall, improving the treatment effect, especially in cases where extensive treatment of anorectal lesions is required.

[0046] In this example, the second fixing strip 242 is also wrapped with a soft material 243. In different examples, the width of the medicine delivery pulley 400 can also be made to exceed the width of the second roller 241, so as to ensure that the medicine delivery pulley 400 wraps the second roller 241 inside.

[0047] In some preferred examples, as described above, a guiding cover 500 extends from the outlet of the second through hole 222. The structure of the guiding cover 500 should not be limited to being integrally formed with the housing 200. A detachable setting or other setting methods should also belong to the equivalent replacement solutions of the structure of this example. Specifically, reference can be made to Figures 4-5For an understanding of the structure shown, in this example, guiding covers 500 are provided on both sides of the medicine delivery pulley 400. The guiding cover 500 includes a vertical channel 510 which communicates with the first chamber 252, and a third through hole 520 is formed in the vertical channel 510. For a better understanding here, the two side surfaces of the medicine delivery pulley 400 are respectively defined as an outer side surface 410 and an inner side surface 420. The vertical channel 510 extends above the outer side surface 410 of the medicine delivery pulley 400, and the third through hole 520 is located above the outer side surface 410 of the medicine delivery pulley 400. A baffle 530 extends from the top of the vertical channel 510 towards the medicine delivery pulley 400. It can be understood that under the guidance of the baffle 530, the medicine will be released from the third through hole 520 along the vertical channel 510 onto the outer side surface 410 of the medicine delivery pulley 400. The baffle 530 plays a guiding role to ensure that the medicine is directly and evenly applied to the outer side surface 410 of the medicine delivery pulley 400. The vertical channel 510 in the guiding cover 500 enables the medicine to form a certain pressure when being released through the third through hole 520 so that the medicine can be continuously delivered onto the medicine delivery pulley 400.

[0048] In some specific examples, the first chamber 252 is further provided with a medicine delivery component 600. In different specific embodiments, the structure of the medicine delivery component 600 can be different. For example, a piston push rod device, or the medicine delivery component 600 is arranged outside the first chamber 252, such as using an existing syringe as the medicine delivery component 600. Subsequently, taking Figure 2 the situation shown as an example, the medicine delivery component 600 includes two rotating members 610 and a number of balls 620 clamped between the two threaded rotating members 610. Specifically, the rotating member 610 is a screw rod. More specifically, a groove is provided between every two adjacent turns of the screw rod for accommodating the balls 620. For a better illustration, the two rotating members 610 in this example are defined as a left rotating member 611 and a right rotating member 612. The left rotating member 611 and the right rotating member 612 rotate in opposite directions. One end of the left rotating member 611 and the right rotating member 612 is connected to the driving mechanism 300, and the other end is rotatably connected to the housing 200.

[0049] In this example, the driving mechanism 300 is used to drive the left rotating member 611 and the right rotating member 612 to rotate. The specific structure will be described in detail in the subsequent text. Here, in combination with Figure 2 understanding the fixing relationship between the housing 200 and the left rotating member 611 and the right rotating member 612, in Figure 2In the structure shown, two third fixing bars 630 are provided in the first chamber 252 in the direction close to the round head end 240. The third fixing bars 630 are of a long strip structure, and both ends of the long strip structure are respectively fixed on the inner side walls of the upper and lower flat shell bodies 220. A first rotating groove 631 is provided in the middle section of the third fixing bar 630, and the first rotating groove 631 is rotationally connected to the ends of the left rotating member 611 / right rotating member 612.

[0050] The drug delivery assembly 600 can evenly deliver the drug in the first chamber 252 through the rotation of the threaded column and the ball 620. For example, referring again to Figure 2 In the structure shown, both the left rotating member 611 and the right rotating member 612 rotate outward. Specifically, taking the direction towards the round head end 240 as a reference, the left rotating member 611 rotates counterclockwise, and the right rotating member 612 rotates clockwise; in this example, the drug delivery assembly 600 can evenly deliver the drug in the first chamber 252 through the interaction of the rotation of the threaded column and the ball 620. When the driving mechanism 300 is started, the left rotating member 611 and the right rotating member 612 start to rotate in opposite directions. The ball 620 between the two screws moves in the threaded groove body, thereby pushing the drug stored in the first chamber 252 towards the direction of the feed pulley 400.

[0051] Due to the threaded design of the screw and the sliding of the ball 620, this drug delivery assembly 600 can achieve continuous and uniform drug delivery, ensuring that the drug will not cause low or uneven drug delivery efficiency due to concentrated release or blockage.

[0052] Combined with the foregoing example structure, further referring to Figure 3 For a further understanding of the driving mechanism 300, the driving mechanism 300 includes a driver 320. Specifically, the driver 320 is a motor, and the motor includes a first output end and a second output end provided at both ends in the second direction (not shown in Figure 3 due to occlusion). In this example, the first end and the second end output rotational power. Two first bevel gears 330 are respectively provided at the first output end and the second output end, and the central axis of the first bevel gear 330 is arranged in the second direction; two second bevel gears 340 are respectively fixed to the ends of the left rotating member 611 and the right rotating member 612, and the central axis of the second bevel gear 340 is arranged in the first direction. In this example, the power is transmitted after the bevel gear surfaces of the first bevel gear 330 and the second bevel gear 340 are engaged.

[0053] The first roller 310 is fixedly arranged on the housing 200 through a first fixing strip 350. Among them, the first roller 310 and the motor are both arranged in the first direction. One end of the first fixing strip 350 is fixed to the inner side wall of the arc-shaped housing 210, and the other end extends out of the second rotating groove 321. The two ends of the first roller 310 in the second direction extend out short cylinders 311, and the short cylinders 311 are sleeved in the second rotating groove 321 and are rotatably connected to the second rotating groove 321. The short cylinders 311 on both sides and the first output end and the second output end are driven by a first belt pulley 360. The first belt pulley 360 drives the first roller 310 to rotate, and the first roller 310 drives the medicine delivery belt pulley 400 to move.

[0054] It can be understood that in the anorectal administration device in this example, the motor is connected to the first bevel gears 330 through the first output end and the second output end at both ends thereof. These first bevel gears 330 are arranged in the second direction, and their central axes are aligned with the output shaft of the motor. When the motor is started, the first bevel gears 330 start to rotate, transmitting power to the meshing second bevel gears 340. These second bevel gears 340 are fixed at the ends of the left rotating member 611 and the right rotating member 612, and their central axes are arranged along the first direction. Thus, the rotational power of the motor is successfully converted in direction and transmitted to the left rotating member 611 and the right rotating member 612, causing them to rotate in opposite directions. Such a design allows the left rotating member 611 and the right rotating member 612 to effectively push the medicine in the first chamber 252 towards the medicine delivery belt pulley 400 through their screw structures and the balls 620, realizing continuous and uniform medicine delivery.

[0055] In addition, the motor also drives the medicine delivery belt pulley 400 through the first belt pulley 360 transmission system. The first belt pulley 360 is arranged at the first output end and the second output end and is connected to the short cylinders 311 extending from both ends of the first roller 310. When the motor is started, the first belt pulley 360 rotates, driving the connected short cylinders 311, thereby driving the first roller 310 to rotate. The rotation of the first roller 310 further pushes the medicine delivery belt pulley 400 to move along the rectal direction, completing the process of delivering and evenly applying the medicine.

[0056] In this example, driven by one motor, the conveying speed of the medicine delivery belt pulley 400 can be kept matching the medicine delivery speed of the internal medicine delivery mechanism, and the medicine can be applied evenly.

[0057] Combined with the foregoing example, combine Figures 6-7 to understand the second aspect embodiment of the present invention.

[0058] In this example, a feeding head 700 is disclosed. The feeding head 700 cooperates with the anorectal administration device and is used for delivering medicine to the first chamber 252.

[0059] Reference Figure 6 As shown, the feeding head 700 includes a splicing pipe 710. Specifically, the splicing pipe 710 can be a threaded pipe, and the splicing pipe 710 is used to connect the pipeline of the medicine storage device; the splicing pipe 710 continues to extend out of the disk body 720, and the disk body 720 is convenient for the user to hold; the disk body 720 continues to extend out of the arc-shaped feeding nozzle 730. The arc-shaped feeding nozzle 730 is an arc-shaped pipeline. In this example, the diameters of the two ends of the arc-shaped feeding nozzle 730 are different. The large-mouth end is connected to the splicing pipe 710, and the small-mouth end is used to probe into the first chamber 252.

[0060] Continue to refer to Figure 7 In the structure shown, a fourth through hole is formed in the partition plate 251, and the third through hole 520 is used to pass through the small-mouth end of the arc-shaped feeding nozzle 730. It is not difficult to understand that when the medicine enters the fourth through hole through the small-mouth end of the arc-shaped feeding nozzle 730, the size of the fourth through hole is closely matched with the small-mouth end of the arc-shaped feeding nozzle 730, and the medicine is effectively delivered into the first chamber 252.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
