[0002] Anorectal diseases refer to diseases that occur in the anorectal area and some colon diseases. There are more than 70 types of diseases recorded in medical records, of which the most common are those that occur in the anorectal intestine. Currently, the number of patients with anorectal diseases is huge.

[0003] Traditional anorectal postoperative care medication devices generally use ordinary syringes, but when the drug solution is injected into the anorectal area, if the muscles in the anus lose their ability to tighten, the drug solution will quickly flow out and fail to exert its efficacy, and the liquid medicine automatically falls to a local position in the anorectal area under its own gravity, and cannot be evenly injected into the wound in the anorectal area. For example, the "Replaceable medication device for anorectal care" disclosed in the Chinese invention patent (application number: CN202010082341.3) discloses that traditional anorectal medication devices are mostly disposable products, and the medication is uneven, resulting in large waste.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the scheme of this application:

[0029] 1. In order to solve the technical problem that when a visual flexible anorectal multifunctional drug delivery device is used, the muscles in the anus lose their ability to tighten, the liquid medicine will flow out quickly and cannot exert its efficacy, and the liquid medicine automatically falls to a local position in the anus under its own gravity, and cannot be evenly injected into the wound in the anus, the present application provides a rotating disk and a drug delivery head assembly, and the rotating disk cooperates with the first push block in the drug delivery cylinder to realize that the liquid medicine in the drug cartridge is rotated and squeezed out, so that the medicine is effectively and evenly sprayed on the wound. In addition, the liquid medicine is squeezed into a water drop shape by squeezing and falls on the wound, which can effectively reduce the outflow of the medicine, improve the efficacy of the medicine, avoid the waste of the medicine, and solve the problem of insufficient efficacy due to the outflow of the medicine and the need for multiple injections;

[0030] 2. By setting the shape transformation of one end of the screw rod and cooperating with the slot opened in the rotating disk, the drug delivery head assembly, the drug delivery cylinder and the rotating disk can be quickly installed, which solves the problem of the complicated process of installing the drug delivery head and the drug delivery cylinder by bolts in the prior art. Moreover, the installation by the shape transformation of the screw rod eliminates the design of redundant installation structure, thereby effectively improving the utilization rate of the structure and reducing the cost;

[0031] 3. The screw rod is provided to cooperate with the first push block and the second push block, so that the drug delivery head assembly and the drug delivery cylinder are connected by one screw rod, which solves the problem of the complicated process of installation by two bolts in the prior art and improves the efficiency of installation;

[0032] 4. By pulling the set pull line and cooperating with the rotating block, the rotating block drives the rotating rod to rotate, so that the cleaning block can reciprocate along the outer wall of the semicircular cover, which solves the problem that the front of the micro camera and the lighting lamp in the prior art is blocked by the secretions in the anorectal cavity, affecting the doctor's observation and judgment, and improves the reliability of the drug delivery device. In addition, when the patient urgently needs to inject drugs into the anorectal cavity, the process of the patient's prior anorectal cleaning can be omitted, which greatly improves the timeliness of treatment;

[0033] 5. Through the solid medicine storage rack, the required solid granular medicine can be placed in the solid medicine storage rack before the applicator is inserted into the anus. By pulling the pull line, the cleaning block can reciprocate along the outer wall of the semicircular cover. At this time, the cleaning block no longer blocks the solid granular medicine, so that the granular medicine falls into the anus and intestines, solving the problem that the liquid applicator in the prior art can only give liquid medicines, effectively improving the applicability of the applicator. In addition, the paste-like medicine can also be administered by the administration method of the liquid drug, thereby further improving the applicability of the applicator;

[0034] 6. The solid granular medicine can be administered by cooperating with the solid medicine storage rack through the cleaning block. When the cleaning block is not performing cleaning work, the solid granular medicine can be administered, eliminating the design of redundant installation structure, thereby effectively improving the utilization rate of the structure and reducing costs.

Obviously, the described embodiments are only part of the embodiments of the present invention, not 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 should fall within the scope of protection of the present invention.

[0054] As described in the background technology, traditional anorectal postoperative care medication devices generally use ordinary syringes, but when the drug solution is injected into the anus, the muscles in the anus lose their ability to tighten, the drug solution will quickly flow out and cannot exert its efficacy, and the liquid drug automatically falls to a local position in the anus under its own gravity and cannot be evenly injected into the wound in the anus.

[0055] In order to solve this technical problem, the present invention provides a visualized flexible anorectal multifunctional drug delivery device and method, which are used to reduce the outflow of liquid medicine and improve the uniformity of liquid medicine injection.

[0056] Specifically, refer to Figure 1 , Figure 3 - Figure 7 and Fig. 9 - Fig.11 The visual flexible anorectal multifunctional drug delivery device comprises a drug delivery cylinder 2 for containing liquid or paste medicine, a drug delivery head assembly 1 for uniformly squeezing the liquid or paste medicine is inserted into the drug delivery cylinder 2, and a rotating disk 3 for cooperating with the drug delivery head assembly 1 for drug delivery is provided at one end of the drug delivery cylinder 2;

[0057] The drug delivery head assembly 1 includes a rotating cylinder 12, one end of which is rotatably in contact with one end of the drug delivery cylinder 2, and a screw 6 is fixedly connected in the middle of the rotating cylinder 12 to cooperate with the rotating disk 3 for transmission. One end of the screw 6 passes through the interior of the drug delivery cylinder 2, and the end of the screw 6 passing through the interior of the drug delivery cylinder 2 can be used to quickly assemble the drug delivery head assembly 1, the drug delivery cylinder 2 and the rotating disk 3 by conversion, so that the drug delivery device is more convenient and quick to use;

[0058] The inner wall of the drug delivery cylinder 2 is provided with a slide groove 22, and the screw rod 6 is spirally connected with a first push block 23, and the side wall of the first push block 23 is slidably connected inside the slide groove 22, and the slide groove 22 is used to limit the first push block 23 so that it will not rotate inside the drug delivery cylinder 2;

[0059] The rotating cylinder 12 is provided with a plurality of buffer grooves 124 of the same size, the buffer grooves 124 are communicated with the outside, the buffer grooves 124 are rotatably connected with a drainage plate 121 for controlling the inflow and outflow of medicine, the drainage plate 121 is located on the outer side wall of the rotating cylinder 12, and both sides of the rotating end of the drainage plate 121 are fixedly connected with a sealing telescopic member 122, one end of the sealing telescopic member 122 is fixedly connected to the side wall of the buffer groove 124, and the sealing telescopic member 122 is used to prevent the medicine from flowing out from the rotating end of the drainage plate 121;

[0060] The present invention provides a visualized flexible anorectal multifunctional drug delivery device, which reduces the outflow of liquid medicine, improves the uniformity of liquid medicine injection, improves the efficacy of the medicine, and avoids the waste of the medicine.

[0061] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0062] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0063] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0064] Example 1, please refer to Figure 5 and Fig.11 , a visualized flexible anorectal multifunctional drug delivery device, wherein the buffer groove 124 is internally rotatably connected with a buffer plate 125, the buffer plate 125 is located on the inner side wall of the rotating cylinder 12, and both sides of the rotating end of the buffer plate 125 are fixedly connected with a sealing telescopic member 122 for preventing the medicine from flowing out of the rotating end of the buffer plate 125, one end of the sealing telescopic member 122 is fixedly connected to the side wall of the buffer groove 124, and the inner side of one end of the rotating connection point of the buffer plate 125 is fixedly connected with an elastic belt 123 for resetting the buffer plate 125. When the interior of the rotating cylinder 12 is filled with medicine, At this time, the horizontal squeezing force of the medicine on the buffer plate 125 is smaller than the horizontal pulling force of the elastic belt 123 on the buffer plate 125, thereby ensuring that the medicine will not flow into the buffer groove 124 before the drug administration action is performed. If the medicine has filled the inside of the buffer groove 124, the screw 6 drives the first push block 23 to push the medicine upward. When the medicine fills the inside of the rotating cylinder 12 and the buffer groove 124, the drainage plate 121 in the initial state is blocked by the limit rod 21, and the medicine cannot be discharged from the drainage plate 121. At this time, the first push block 23 can no longer squeeze the medicine, so that the drug dispenser cannot administer liquid or paste medicine.

[0065] Further, such as Figure 5 and Fig.11 As shown, the heights of the buffer plate 125 and the drainage plate 121 are the same as the height of the buffer groove 124, and the height of the sealing telescopic member 122 is the same as the height of the buffer groove 124, thereby preventing the medicine from flowing out and causing waste of the medicine. The elastic belt 123 is located between the sealing telescopic members 122 on both sides of the rotating end of the buffer plate 125, so that the medicine will not contact the elastic belt 123, thereby preventing the medicine from chemically damaging the elastic belt 123 due to long-term use of the applicator.

[0066] Example 2 further optimizes the visual flexible anorectal multifunctional drug delivery device provided in Example 1. Specifically, Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, one end of the dosing cylinder 2 is fixedly connected to a limit rod 21 for controlling the switch of the drainage plate 121. The number of the limit rods 21 is the same as the number of the drainage plates 121. One end of the limit rod 21 is a free end. When the screw 6 is fully screwed into the dosing cylinder 2, the limit rod 21 is located in the middle position of the outer side of the drainage plate 121, blocking the drainage plate 121 so that the medicine in the rotating cylinder 12 cannot overflow.

[0067] Example 3 further optimizes a visualized flexible anorectal multifunctional drug delivery device provided in Example 1 or 2. Specifically, Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, a T-shaped circular groove is provided inside one end of the screw rod 6, a disc 62 is placed at the horizontal end of the T-shaped circular groove, and the vertical end of the T-shaped circular groove is communicated with the outside, an arc-shaped groove 621 is provided inside the disc 62, and the arc-shaped groove 621 can be driven to rotate by rotating the disc 62, and a locking block groove 63 is also provided inside one end of the screw rod 6, and an L-shaped locking block 64 is slidably connected inside the locking block groove 63, and the shorter end of the L-shaped locking block 64 is located inside the arc-shaped groove 621, and the arc-shaped groove 621 can change its position by rotating, and the position of the L-shaped locking block 64 in the locking block groove 63 can be controlled;

[0068] Further, such as Figure 1 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, the interior of the rotating disk 3 is provided with a slot 31 for cooperating with an L-shaped locking block 64 to fix the screw 6, the drug delivery cylinder 2 and the rotating disk 3 together. A rotating head 65 is fixed to the lower end surface of the disk 62. One end of the rotating head 65 passes through the vertical end of the T-shaped circular groove. The rotating head 65 can be rotated to drive the disk 62 to rotate.

[0069] Further, such as Figure 3 As shown, the outer wall of the screw rod 6 is spirally connected with a second push block 24, and the second push block 24 is fixedly connected to the first push block 23. The second push block 24 is located above the first push block 23. When the first push block 23 rises to the end of the slide groove 22, the remaining medicine inside the rotating cylinder 12 can be squeezed out by the second push block 24.

[0070] Example 4 further optimizes a visualized flexible anorectal multifunctional drug delivery device provided in Example 1, 2 or 3. Specifically, Figure 2 , Figure 3 and Figure 8As shown, the upper end of the rotating cylinder 12 is fixedly connected with a semicircular cover 11 for inserting the applicator into the anus more conveniently and comfortably. The semicircular cover 11 is made of transparent and flexible material. The outer wall of the semicircular cover 11 is provided with a groove 111 for avoiding squeezing hemorrhoids when the applicator is inserted into the anus, thereby effectively reducing squeezing of hemorrhoids and reducing the discomfort of patients during medication. The outer wall of the semicircular cover 11 is provided with a rotating rod groove for facilitating the rotation of the rotating rod 18, and the rotating rod groove and the groove 111 are perpendicular to each other. The outer wall of the semicircular cover 11 is also provided with a solid medicine outlet groove, one end of the screw rod 6 is symmetrically fixedly connected with a rectangular block 13, a rotating shaft is rotatably connected between the two rectangular blocks 13, a rotating block 14 is fixedly connected to the outer wall of the rotating shaft, a torsion spring 141 for resetting the rotating block 14 is fixedly connected between the rotating block 14 and the rotating shaft, one end of the torsion spring 141 is fixedly connected with the rectangular block 13, and when the torsion spring 141 is in the initial state, the rotating block 14 is in a horizontal state with one end facing the direction of the cleaning block 17;

[0071] Further, such as Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, a wire groove 61 is provided inside the screw 6, the disc 62 and the rotating head 65, and a pull wire 15 for pulling the rotating block 14 to rotate is passed through the inside of the wire groove 61, one end of the pull wire 15 is fixedly connected to the upper side of the rotating block 14, and the other end of the pull wire 15 is fixedly connected to the pulling block 151, one end of the rotating block 14 is fixedly connected to a rotating rod 18, and one end of the rotating rod 18 is fixedly connected to a cleaning block 17, and the cleaning block 17 is located in front of the solid medicine outlet groove for shielding the solid granular medicine, and a solid medicine storage rack 16 for placing solid granular medicine is provided above the rotating cylinder 12, and a slot for passing the rotating rod 18 is provided in the middle position of the solid medicine storage rack 16, and a miniature camera 4 and a lighting lamp 5 for providing an internal picture of the anorectal are also provided above the rotating cylinder 12, and the miniature camera 4 and the lighting lamp 5 here are prior art and are not described in detail.

[0072] Example 5, please refer to Figure 1 - Fig.11 , a method for using a visualized flexible anorectal multifunctional drug delivery device, comprising the following steps:

[0073] When liquid medicine needs to be given, the steps for use are as follows:

[0074] S1. First, place the dosing head assembly 1 inside the dosing barrel 2, align the screw 6 with the thread groove of the second push block 24, and screw the screw 6 into the second push block 24 and the first push block 23 in sequence to connect the dosing head assembly 1 with the dosing barrel 2, and continue to screw the screw 6 into the inside of the dosing barrel 2 until two-thirds of the dosing head assembly 1 is screwed into the dosing barrel 2;

[0075] S2, then add the prepared liquid medicine from S1 into the remaining one-third of the gap between the dosing head assembly 1 and the dosing cylinder 2 into the dosing cylinder 2;

[0076] S3, then completely screw the medicine head assembly 1 into the drug delivery barrel 2, and insert the rotating disk 3 into one end of the screw 6, as shown in the attached Fig.10 As shown, by twisting the rotating head 65 counterclockwise, the rotating head 65 drives the disc 62 to rotate counterclockwise, and the disc 62 pushes the L-shaped locking block 64 from one end of the locking block groove 63 to the other end of the locking block groove 63 through the arc groove 621, and the longer end of the L-shaped locking block 64 enters the slot 31, thereby realizing the assembly of the medicine head assembly 1, the drug delivery cylinder 2 and the rotating disk 3. At this time, one side of the rotating cylinder 12 is in sliding contact with one end of the drug delivery cylinder 2, that is, the rotating cylinder 12 can rotate relative to the surface of one end of the drug delivery cylinder 2. At the same time, one end of the limiting rod 21 is in sliding contact with the surface of the lower end of the rotating cylinder 12, that is, the rotating cylinder 12 can rotate relative to the surface of one end of the limiting rod 21. In addition, the outside of the drug delivery device is sterilized again;

[0077] S4. For patients with hemorrhoids, first confirm the location of the hemorrhoids, align the groove 111 with the hemorrhoids, and then slowly insert the sterilized applicator into the anus, and judge the location of the wound by observing the picture taken by the micro camera 4 on the computer, and then insert the applicator into the wound;

[0078] When the front of the micro camera 4 and the illuminating lamp 5 is blocked by secretions from the anorectal area, the pull block 151 can be pulled, and the pull block 151 drives the pull wire 15 to move downward along the wire groove 61, and the pull wire 15 pulls the rotating block 14 to deflect from one end to the other end, and the rotating block 14 drives the cleaning block 17 to rotate half a circle along the outer surface of the semicircular cover 11 through the rotating rod 18, and cleans and removes the obstruction in front of the semicircular cover 11, and then, under the restoring force of the torsion spring 141, the cleaning block 17 automatically resets, and the semicircular cover 11 is cleaned again during the reset process. If it is still not cleaned, the above-mentioned actions can be repeated until the picture taken by the micro camera 4 can be observed;

[0079] S5. When the depth of the drug delivery device reaches the designated wound, one hand grasps the end of the drug delivery cylinder 2, and the other hand rotates the rotating disk 3. The rotating disk 3 drives the screw 6 to rotate through the L-shaped locking block 64, and the screw 6 drives the rotating cylinder 12 to rotate, and the rotating cylinder 12 drives the drainage plate 121 and the buffer plate 125 to rotate. At the same time, the screw 6 drives the first push block 23 to move upward along the slide groove 22, and the first push block 23 drives the second push block 24 to move upward. The liquid medicine is pushed upward from the lower end of the drug delivery cylinder 2 by the first push block 23 and the second push block 24 until the interior of the rotating cylinder 12 is also filled with liquid medicine. At this time, the limit rod 21 is just located in the middle position of the outer side of the drainage plate 121, which blocks the drainage plate 121, so that the medicine in the rotating cylinder 12 cannot overflow.

[0080] By continuing to rotate the rotating disk 3, the first push block 23 and the second push block 24 continue to squeeze the liquid medicine upward. Since the interior of the rotating cylinder 12 is already full of liquid medicine, the liquid medicine cannot be squeezed upward any more. Here, if the buffer groove 125 is not designed, the rotating disk 3 cannot be rotated any more. At this time, the liquid medicine begins to squeeze the buffer plate 125 on the inner wall of the rotating cylinder 12. The buffer plate 125 deflects into the buffer groove 124. The liquid medicine flows from the rotating cylinder 12 to the interior of the buffer groove 124. The amount of liquid medicine flowing into the buffer groove 124 just meets the rotation of the screw 6 and a drainage plate 121. The distance of the length of the liquid discharge plate 121 is changed. As the position of the liquid discharge plate 121 rotates, the limiting rod 21 no longer blocks the liquid discharge plate 121, and the liquid medicine is squeezed out from one side of the buffer groove 124 and falls evenly on the wound. When the liquid medicine in the buffer groove 124 is squeezed out, the position of the liquid discharge plate 121 rotates again due to the rotation of the screw 6. The limiting rod 21 continues to block the liquid discharge plate 121, and the liquid medicine is squeezed from the rotating cylinder 12 into the buffer groove 124 again, and is squeezed out from one side of the buffer groove 124. After the liquid medicine is injected, the applicator is slowly taken out.

[0081] By rotating the rotating head 65 in the opposite direction, the rotating disk 3 is removed, and one end of the drug delivery head assembly 1 is grasped and twisted in the opposite direction, so that the screw 6 is disengaged from the first push block 23 and the second push block 24, so that the drug delivery head assembly 1 is separated from the drug delivery barrel 2, and the disassembled drug delivery device can be subsequently disassembled and disinfected;

[0082] When a paste-like medicine is to be administered, the steps for its use are the same as those for liquid medicines;

[0083] When solid granular drugs need to be administered, the steps for use are as follows:

[0084] S1. First, assemble the dosing head assembly 1, the dosing cylinder 2 and the rotating disk 3;

[0085] S2, then manually pull the pull block 151 downward, so that the cleaning block 17 rotates to the other end of the semicircular cover 11, and the solid granular medicine is placed inside the solid medicine storage rack 16;

[0086] S3, release the pull block 151, under the restoring force of the torsion spring 141, the cleaning block 17 is reset, and the solid granular medicine is blocked inside the solid medicine storage rack 16, and then the outside of the drug delivery device is sterilized;

[0087] S4. For patients with hemorrhoids, first confirm the location of the hemorrhoids, align the groove 111 with the hemorrhoids, and then slowly insert the sterilized applicator into the anus, and judge the location of the wound by observing the picture taken by the micro camera 4 on the computer, and then insert the applicator into the wound;

[0088] S5. When the depth of the drug delivery device reaches the designated wound, grasp the end of the drug delivery cylinder 2 with one hand and pull the pull block 151 downward with the other hand, so that the cleaning block 17 rotates to the other end of the semicircular cover 11. The solid granular medicine falls from the solid medicine storage rack 16 to the wound under the action of its own gravity. Then, slowly take out the drug delivery device, disassemble it, and then disassemble and disinfect it.
