Description

Technical Field

[0001] The invention belongs to the technical field of anorectal treatment instruments, in particular to a drug delivery device used for anorectal treatment in traditional Chinese medicine. Background Art

[0002] There are many ways of administering medicine for anorectal treatment in traditional Chinese medicine, mainly including suppository medication, ointment medication, lotion bath and anorectal injection, etc. Anorectal injection mainly injects the medicine into the anorectal through the medication device, and the medicine entering the anorectal will be absorbed by the anorectal to achieve the purpose of treatment; However, in the process of injecting medicine into the anus and rectum using a drug delivery device, the patient needs to contract the anus to prevent the medicine from flowing out of the anus. According to relevant technologies, in order to solve the problem of the medicine flowing out, an inflatable ring is used to expand in the anus and rectum, thereby preventing the medicine from flowing out. Although the above method can prevent the drug from flowing out, since the anorectum has a certain length and the drug has a certain fluidity, when the drug enters the anorectum, it will flow in the anorectum. Therefore, the drug cannot be gathered at the lesion. Some of the drug far away from the lesion cannot be absorbed by the lesion, which will affect the absorption of the drug and the therapeutic effect. Summary of the invention

[0005] Preferably, the two active rods slide in the rotating ring; The tops of the two active rods are fixedly connected to the second paddles, and the two second paddles are arranged alternately with the first paddles; An annular groove is provided in the filling block, and in an initial state, both the first paddle and the second paddle are located in the annular groove.

[0006] Preferably, a liquid outlet pipe is installed on the left side of the driving pipe in the fixed plate, and the liquid outlet pipe passes through the fixed block at the bottom and is slidably connected with the fixed block; The tops of the liquid inlet pipe and the liquid outlet pipe are fixedly connected to the sealing block, and the sealing block is in contact with the top of the fixed plate in the initial state; Liquid ports are provided in the inner walls of the liquid inlet pipe and the liquid outlet pipe below the two sealing blocks; and the liquid inlet pipe and the liquid outlet pipe are slidable in the fixed plate.

[0011] The beneficial effects of the present invention are as follows: 1. The drug delivery device for TCM anorectal treatment described in the present invention can adjust the distance between the upper and lower cannulas according to the range of the lesion by setting an upper cannula and a lower cannula that can be separated from each other, thereby ensuring that the lesion is located between the upper and lower cannula, and at the same time cooperate with the first expansion bladder and the second expansion bladder to block the position above and below the lesion, so that the medicine can be gathered at the lesion, so that the lesion can better absorb the medicine, avoiding the waste caused by the inability to completely absorb the medicine, and at the same time avoiding the situation that when the medicine is injected, the medicine gradually increases, causing the medicine to flow in the anorectum, resulting in part of the medicine moving away from the lesion, and part of the medicine away from the lesion cannot be absorbed by the lesion, thereby affecting the absorption of the medicine and the treatment effect.

[0012] 2. The drug delivery device for traditional Chinese medicine anorectal treatment described in the present invention has a first paddle fixedly connected and evenly arranged above the rotating ring. Therefore, during the rotation of the rotating ring, the first paddle will drive the first paddle to rotate back and forth. The rotating first paddle will stir the medicine liquid to roll, thereby avoiding the precipitation of the medicine liquid, resulting in part of the precipitated medicine liquid being unable to be absorbed by the lesion. At the same time, during the tumbling of the medicine liquid, the medicine liquid originally located on the farther side of the lesion will flow to the lesion, thereby allowing the medicine liquid to be fully absorbed. By adjusting the position of the active rod and the second paddle, it can be avoided that the first paddle can only stir the medicine liquid below due to the distance between the upper cannula and the lower cannula being too far. The moved active rod and the second paddle can stir the medicine liquid in the middle or even above, thereby increasing the tumbling degree of the medicine liquid and enabling better absorption at the lesion.

[0013] 3. The drug delivery device for traditional Chinese medicine anorectal treatment described in the present invention, when the drug liquid is absorbed, the staff pushes the liquid outlet tube upward, and the liquid outlet on the liquid outlet tube moves to above the fixed plate. At this time, the drug liquid between the upper cannula and the lower cannula will flow out from the liquid outlet tube, and the medical staff can collect the flowing drug liquid. In this process, the drug liquid can be discharged through the liquid outlet tube, thereby avoiding contamination of the liquid inlet tube when the drug liquid is discharged through the liquid inlet tube. At the same time, after the drug liquid is discharged, when the cannula is pulled out, it can be avoided that the drug liquid flows out of the anus, causing the drug liquid to drip onto the bed or the medical staff.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figures 1 to 9 As shown, the drug delivery device for traditional Chinese medicine anorectal treatment of the present invention comprises a drug delivery device; the drug delivery device comprises a cannula; The cannula is composed of an upper cannula 1 and a lower cannula 2. In the initial state, the upper cannula 1 and the lower cannula 2 fit each other. The top of the upper cannula 1 is a hemispherical surface. The interior of the upper cannula 1 is fixedly connected to a filling block 11. The outer ring surface of the upper cannula 1 is fixedly connected to a first expansion bag 12. The lower insert tube 2 is cylindrical; the lower insert tube 2 is close to the upper insert tube 1 on one side, and the outer surface of the lower insert tube 2 is fixedly connected to the second expansion bag 21; A sealing disk 3 is installed inside the lower insert tube 2 on one side of the lower insert tube 2 close to the upper insert tube 1; a driving tube 13 is rotatably connected inside the filling block 11 inside the upper insert tube 1, and the driving tube 13 passes through the middle of the sealing disk 3 and is slidably connected to the sealing disk 3; The driving tube 13 extends to the position below the lower inserting tube 2; the middle of the driving tube 13 is a dividing line, and the surface of the driving tube 13 below the dividing line is provided with threads; The sealing disc 3 is fixedly connected to a fixing block 22 at the bottom; a thread groove is provided in the middle of the fixing block 22, and the driving pipe 13 passes through the thread groove and is threadedly engaged with the thread groove; A liquid inlet pipe 31 is installed on the sealing disk 3 on the right side of the driving pipe 13, and the bottom of the liquid inlet pipe 31 passes through the fixed block 22 and is slidably connected to the fixed block 22; The upper insert tube 1 and the inner wall of the filling block 11 are provided with a first air passage 14, and the two ends of the first air passage 14 are respectively connected with the driving tube 13 and the first expansion bag 12; the inner wall of the lower insert tube 2 is provided with a second air passage 23, and the second air passage 23 is connected with the second expansion bag 21; Specifically, when applying medicine to the patient, the medical staff slowly inserts the cannula from the patient's anus. When the cannula gradually enters the anorectum, it gradually approaches the lesion. When the upper cannula 1 contacts the lesion of the patient, the patient's feeling and feedback indicate that the upper cannula 1 is already at the lesion. Then the medical staff stops inserting the entire cannula into the anorectum, and then controls the upper cannula 1 to move upward alone. More specifically, first the medical staff rotates the drive tube 13. Since the thread on the lower part of the drive tube 13 is engaged with the thread on the fixing block 22, when the drive tube 13 is rotated, the drive tube 13 will gradually move to the position of the upper cannula 1. At the same time, the drive tube 13 will drive the upper cannula 1 to move alone in the anus and rectum. The moving upper cannula 1 will gradually pass through the lesion on the anus and rectum. When the moving upper cannula 1 completely passes through the lesion, it can be known from the patient's feeling and feedback that the upper cannula 1 has passed through the lesion, and the lesion is located between the upper cannula 1 and the lower cannula 2, and then the rotation is stopped. The driving tube 13 is activated, and then the staff inserts the inflation tube into the driving tube 13 and the second airway 23. The gas entering the driving tube 13 will gradually enter the first airway 14, and then the gas in the first airway 14 will enter the first expansion bag 12, and the first expansion bag 12 will expand. The expanded first expansion bag 12 can block the position above the lesion. At the same time, the gas entering the second airway 23 will enter the second expansion bag 21, and then the second expansion bag 21 will also expand and block the position below the lesion, and then the drug can be administered into the anorectal cavity; Furthermore, when administering the medicine, the medical staff connects the bottom of the liquid inlet tube 31 with the catheter, and then gradually injects the liquid medicine into the liquid inlet tube 31. The liquid medicine entering the liquid inlet tube 31 will gradually flow to the top of the sealing disk 3. As the amount of liquid medicine injected gradually increases, the liquid level of the liquid medicine between the upper cannula 1 and the lower cannula 2 gradually increases. Since the first expansion bladder 12 and the second expansion bladder 21 can block the position above and below the lesion, the liquid medicine can be prevented from flowing in the anorectum. When the liquid medicine is injected, all the liquid medicine is located between the upper cannula 1 and the lower cannula 2. Then the liquid medicine will be absorbed by the lesion, thereby treating the lesion. Furthermore, by providing an upper cannula 1 and a lower cannula 2 that can be separated from each other, the distance between the upper cannula 1 and the lower cannula 2 can be adjusted according to the range of the lesion to ensure that the lesion is located between the upper cannula 1 and the lower cannula 2. At the same time, the first expansion bladder 12 and the second expansion bladder 21 are used to block the position above and below the lesion, so that the medicine can be gathered at the lesion, so that the lesion can better absorb the medicine and avoid the waste caused by the inability to completely absorb the medicine. At the same time, it can be avoided that when the medicine is injected, the medicine gradually increases, causing the medicine to flow in the anus and intestines, causing part of the medicine to move away from the lesion, and part of the medicine away from the lesion cannot be absorbed by the lesion, which will affect the absorption of the drug and the treatment effect.

[0019] Embodiment 2: The sealing disc 3 includes a fixed disc 32 and a rotating ring 35; the lower insert tube 2 is provided with a fixed disc 32; the bottom of the fixed disc 32 is fixedly connected to two connecting plates 33, and the other end of the connecting plate 33 is fixedly connected to the inner wall of the lower insert tube 2; The outer ring surface of the fixed disk 32 is fixedly connected to an annular block 34; the outer ring surface of the fixed disk 32 is rotatably connected to a swivel 35, and the swivel 35 is located above the connecting plate 33 and is higher than the fixed disk 32 as a whole; The inner surface of the rotating ring 35 is provided with an annular slideway 36, and the annular block 34 slides in the annular slideway 36; the driving pipe 13 and the liquid inlet pipe 31 both pass through the fixed plate 32; The upper surface of the rotating ring 35 is fixedly connected to the uniformly arranged first paddles 37; two active rods 38 are installed in the inner wall of the rotating ring 35, and the straight line formed by the two active rods 38 is perpendicular to the fixed block 22 and the connecting plate 33; the two active rods 38 extend to the position below the lower insert pipe 2; In this embodiment, the two active rods 38 slide in the rotating ring 35; The tops of the two active rods 38 are fixedly connected to the second paddles 39, and the two second paddles 39 are staggered with the first paddles 37; The filling block 11 is provided with an annular groove 15, and in an initial state, the first paddle 37 and the second paddle 39 are both located in the annular groove 15; Specifically, after the liquid medicine is injected between the upper cannula 1 and the lower cannula 2, while the lesion absorbs the liquid medicine, the medical staff can hold the two active rods 38 and rotate them. Since the straight line formed by the active rods 38 in the initial state is perpendicular to the connecting plate 33 and the fixed block 22, when the medical staff hold the two connecting rods and rotate them clockwise, the two active rods 38 will gradually approach the fixed block 22. When the active rods 38 contact the fixed block 22, the two active rods 38 are rotated in the opposite direction again. When the active rods 38 rotating in the opposite direction contact the fixed block 22 again, the active rods 38 are rotated clockwise again, and the cycle continues. More specifically, during the process of the active rod 38 cyclically rotating forward and reversely, the rotating ring 35 will be driven to cyclically rotate forward and reversely along the fixed plate 32, and the annular slideway 36 will rotate back and forth along the annular block 34. Since the evenly arranged first paddles 37 are fixedly connected to the top of the rotating ring 35, the first paddles 37 will be driven to rotate back and forth during the rotation of the rotating ring 35. The rotating first paddles 37 will stir the liquid medicine to roll, thereby preventing the liquid medicine from precipitating, causing part of the precipitated liquid medicine to be unable to be absorbed by the lesion. At the same time, during the tumbling of the liquid medicine, the liquid medicine originally located at the far side of the lesion will flow to the lesion, so that the liquid medicine can be fully absorbed. Furthermore, if the distance between the upper cannula 1 and the lower cannula 2 is too far, the medical staff can push the two active rods 38 to move in the rotating ring 35, and the moving active rod 38 will gradually move to the position of the upper cannula 1 and drive the second paddle 39 to move, and then control the two active rods 38 to drive the rotating ring 35 to rotate back and forth. In this process, it can be avoided that the first paddle 37 can only stir the medicine liquid below due to the long distance between the upper cannula 1 and the lower cannula 2. The moved active rod 38 and the second paddle 39 can stir the medicine liquid in the middle or even above, thereby increasing the rolling degree of the medicine liquid and making it better absorbed by the lesion.

[0020] Embodiment 3: The left side of the driving tube 13 is provided with a liquid outlet pipe 4 in the fixed plate 32, and the liquid outlet pipe 4 passes through the fixed block 22 at the bottom and is slidably connected with the fixed block 22; The tops of the liquid inlet pipe 31 and the liquid outlet pipe 4 are fixedly connected to the sealing block 41, and the sealing block 41 is initially in contact with the top of the fixed plate 32; Liquid ports 42 are provided in the inner walls of the liquid inlet pipe 31 and the liquid outlet pipe 4 below the two sealing blocks 41; the liquid inlet pipe 31 and the liquid outlet pipe 4 are slidable in the fixed plate 32; Specifically, since the sealing block 41 is fixedly connected to the liquid inlet pipe 31 and the outlet pipe 4, and the liquid inlet pipe 31 and the liquid outlet pipe 4 are initially located in the fixed disk 32, when injecting liquid medicine, the medical staff pushes the liquid inlet pipe 31 upward and makes the liquid inlet 42 on the liquid inlet pipe 31 located above the fixed disk 32, and the liquid medicine will flow into between the upper cannula 1 and the lower cannula 2 through the liquid inlet 42. When the injection is completed, the liquid inlet pipe 31 is controlled to return to the initial state, and the liquid inlet 42 on the liquid inlet pipe 31 will be sealed in the fixed disk 32; More specifically, when the liquid medicine is completely absorbed, the staff member pushes the liquid outlet tube 4 upward, and the liquid port 42 on the liquid outlet tube 4 moves to above the fixed plate 32. At this time, the liquid medicine between the upper cannula 1 and the lower cannula 2 flows out from the liquid outlet tube 4, and the medical staff collects the flowing liquid medicine. In this process, the liquid medicine can be discharged through the liquid outlet tube 4, thereby avoiding contamination of the liquid inlet tube 31 when the liquid medicine is discharged through the liquid inlet tube 31. At the same time, after the liquid medicine is discharged, when the cannula is pulled out, it can be avoided that the liquid medicine flows out from the anus, causing the liquid medicine to drip onto the bed or the medical staff. Furthermore, when pulling out the cannula, the team members connect the exhaust pipe to the driving pipe 13 and the second airway 23 respectively, and exhaust the first expansion bag 12 and the second expansion bag 21. When the gas in the first expansion bag 12 and the second expansion bag 21 is extracted, the first expansion bag 12 and the second expansion bag 21 will be attached to the surface of the upper cannula 1 and the lower cannula 2. When the cannula is pulled out, the degree of scraping of the lesion by the first expansion bag 12 can be reduced.

[0021] Embodiment 4: The annular layer 351 is fixedly connected to the inner ring surface of the rotating ring 35, and the annular layer 351 is located above the fixed disk 32 and fits with the upper surface of the fixed disk 32; the upper surface formed by the rotating ring 35 and the annular layer 351 is a downwardly concave arc surface; In this embodiment, a squeezing bag 43 is installed on the liquid outlet pipe 4; In this embodiment, after the second expansion bag 21 is inflated, the top end surface is a curved surface; In this embodiment, a sealing ring is provided inside the fixed disk 32 on the side where the driving tube 13, the liquid inlet tube 31 and the liquid outlet tube 4 pass through the fixed disk 32; Specifically, since the upper surface formed by the rotating ring 35 and the annular layer 351 is a downwardly concave arc surface, when the liquid medicine is discharged, the liquid medicine will flow along the downwardly concave arc surface. As the liquid medicine gradually decreases, the liquid medicine will eventually flow completely to the inner circle of the annular layer 351, and then be discharged from the liquid outlet pipe 4. In this process, it can be avoided that part of the liquid medicine remains on the upper surface of the rotating ring 35, causing the residual liquid medicine to drip when the cannula is pulled out; since the top end surface of the second expansion bladder 21 is a curved surface after being inflated, as the liquid medicine level gradually decreases, the liquid medicine will flow downward along the curved surface of the second expansion bladder 21, thereby avoiding part of the liquid medicine remaining on the second expansion bladder 21; More specifically, since the liquid outlet tube 4 is provided with a squeezing bag 43, when the liquid medicine is discharged, if some substances in the anus and intestines block the liquid outlet tube 4, the squeezing bag 43 is pressed, and the liquid medicine in the squeezing bag 43 impacts the liquid outlet tube 4, thereby clearing the liquid outlet tube 4 and preventing the liquid medicine from being blocked and unable to be discharged; Furthermore, due to the sealing ring provided in the fixed disk 32, the driving tube 13, the liquid inlet tube 31 and the liquid outlet tube 4 can be sealed, thereby preventing the liquid from flowing out.
