Description

Technical Field

[0001] This invention relates to the field of constipation medication technology, specifically to a constipation medication device. Background Technology

[0002] The constipation drug delivery device is an anorectal drug delivery device used in the clinical treatment of constipation. It precisely delivers lubricants, laxatives, and other medications into the rectum. Through the contact between the medication and the rectal mucosa, it softens hardened stool and stimulates intestinal peristalsis, thereby helping patients to defecate smoothly. Compared with oral administration, it has the advantages of rapid onset of action, direct drug effect, and less irritation to the gastrointestinal tract. It can reduce the risk of complications such as perianal injury and increased abdominal pressure caused by difficulty in defecation in constipation patients. It is a medical device in the field of anorectal clinical nursing.

[0003] Most current constipation medication devices use a single straight nozzle. When administering medication, the nozzle needs to be inserted into the rectum and sprayed directly into the rectal cavity. However, constipated patients usually have a large amount of feces accumulated in their rectum. The sprayed medication is easily blocked and absorbed by this feces, resulting in most of the medication not being able to effectively contact the rectal mucosa. This makes it difficult for the medication to exert its full effect, requiring patients to administer the medication multiple times to achieve the desired defecation effect. This results in ineffective waste of medication and reduces treatment efficiency.

[0004] To address the above issues, a constipation medication delivery device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a constipation medication delivery device. By using this invention, the problem in the above-mentioned constipation medication delivery device is that the medication is easily blocked and absorbed by feces during administration, resulting in ineffective loss of the medication and reduced treatment efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A constipation medication delivery device includes a reservoir cylinder with a reservoir cavity inside. A medication injection component is connected to one side of the reservoir cylinder. A handle component is located at one end of the reservoir cylinder, and a rotating cylinder is located at the other end. A limit insertion component is slidably disposed on the outer wall of the rotating cylinder. A spiral rotation component is fixedly connected to one end of the rotating cylinder. A pushing component is slidably disposed inside the reservoir cylinder, and the pushing component is respectively disposed within the handle component and the rotating cylinder. A first medication delivery component is connected to one side of the reservoir cavity and is disposed within the spiral rotation component and the pushing component. An ejection component is located on the outer wall of the pushing component and is slidably connected to the rotating cylinder. A plurality of second medication delivery components are connected to one end of the first medication delivery component.

[0007] Furthermore, the drug injection assembly includes a drug injection tube connected to one side of the liquid storage cylinder, the liquid storage chamber is connected to the drug injection tube, and a sealing cap is threaded to one end of the drug injection tube.

[0008] Furthermore, the handrail assembly includes a threaded seat that is threaded to one end of the liquid storage cylinder, and a fixing plate is fixedly connected to one side of the threaded seat, with the fixing plate fitting against one side of the liquid storage cylinder.

[0009] Furthermore, the limiting insertion component includes a sliding sleeve that is slidably connected to the outer wall of the rotating cylinder, a threaded sleeve that is threaded to one end of the sliding sleeve, a positioning sleeve that is fixedly connected inside the sliding sleeve, and a plurality of through slots that are evenly opened on the sliding sleeve.

[0010] Furthermore, the spiral rotation assembly includes a conical rod fixedly connected to one end of the rotating cylinder, with conical spiral blades fixedly connected to the outer wall of the conical rod, and the conical rod slidably connected to the positioning sleeve.

[0011] Furthermore, the pushing assembly includes a slide rod slidably connected to the threaded seat, the slide rod being slidably connected to the inner wall of the liquid storage cylinder, a push rod being fixedly connected to one end of the slide rod, a limit rod being slidably connected to the outer wall of the push rod, a threaded rod being fixedly connected to one end of the limit rod, and the other end of the threaded rod being rotatably connected to the inner wall of the rotating cylinder, a pressure plate being fixedly connected to one end of the slide rod, and a piston being rotatably connected to the outer wall of the slide rod.

[0012] Furthermore, the first drug delivery assembly includes several first outlet pipes connected to one side of the liquid storage cylinder. The first outlet pipes are connected to the liquid storage chamber. One end of the first outlet pipe is connected to a first corrugated pipe, and one end of the first corrugated pipe is connected to a first branch pipe. One side of the first branch pipe is connected to a flexible tube. A second outlet pipe is fixedly connected inside the push rod. One end of several flexible tubes is connected to the second outlet pipe. A first solenoid valve is installed on the second outlet pipe. One end of the second outlet pipe is connected to the second corrugated pipe, and the other end of the second corrugated pipe is connected to a third outlet pipe. The third outlet pipe is fixedly connected to a limiting rod, a threaded rod, and a rotating cylinder, respectively. Several first spray pipes are evenly arranged inside the conical spiral blade. The first spray pipes are connected to the third outlet pipes.

[0013] Furthermore, the ejection assembly includes a threaded post threaded to the outer wall of the threaded rod. The outer wall of the threaded post is evenly provided with several inclined grooves. A slider is slidably connected in the inclined grooves. A push block is fixedly connected to one side of the slider. The push block is slidably connected to the rotating cylinder.

[0014] Furthermore, the second drug delivery assembly includes a second solenoid valve connected to one end of the first branch pipe, and the other end of the second solenoid valve connected to a first drain pipe. One end of the first drain pipe is connected to a third corrugated pipe, and the other end of the third corrugated pipe is connected to a second drain pipe. One end of the second drain pipe is connected to a fourth corrugated pipe, and the other end of the fourth corrugated pipe is connected to a second branch pipe. The second branch pipe is fixedly connected to a push block. One side of the second branch pipe is connected to several second spray pipes. One end of the second spray pipe is connected to a liquid outlet plate. One side of the liquid outlet plate has several liquid outlet holes. Several limiting sleeves and fixing seats are fixedly connected to the inner wall of the rotating cylinder. The first drain pipe is slidably connected to the limiting sleeves, and the second drain pipe is fixedly connected to the fixing seats.

[0015] Furthermore, an arc-shaped surface is provided on one side of the liquid outlet plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The cooperation between the limiting insertion component and the spiral rotation component makes it easy to store the spiral blades in the sliding sleeve, so that the device can be smoothly inserted into the anus. When the insertion is blocked, the limiting component is unlocked, and the spiral blades are rotated to break up the dry feces, avoiding hard pushing and damage to the intestinal mucosa. By cooperating with the first drug delivery component, the helical rotating component can simultaneously spray out the drug to soften the feces while the helical blades break up the dried feces, thereby reducing the resistance of the helical rotation, improving the obstacle clearing efficiency, avoiding the large amount of drug being absorbed by the dried feces, and improving the drug utilization rate. By cooperating with the push component and the ejection component, the threaded rod can be rotated to drive the threaded column to move. The inclined groove pushes the slider to make the push block slide out of the rotating cylinder, allowing the liquid discharge plate to pass smoothly through the through groove and fit against the inner wall of the rectum, facilitating precise drug delivery. The cooperation between the ejector component and the second drug delivery component allows the solenoid valve to be switched after the liquid dispensing plate is attached to the rectal mucosa, so that the drug can be sprayed evenly through the liquid dispensing hole, increasing the contact area between the drug and the intestinal mucosa, reducing the obstruction of feces, improving the drug absorption efficiency, and thus reducing the ineffective loss of the drug.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical challenge of inserting medication delivery devices for constipation into patients, such as... Figures 1-10 As shown, the following preferred technical solutions are provided: like Figures 1-2As shown, a constipation medication device includes a reservoir 1, which can support and fix various components. A controller is provided on the outer wall of the reservoir 1 to control various electrical components. The controller is existing technology and is not shown in the figure. A reservoir cavity 11 is opened inside the reservoir 1 for temporarily storing the medication used to treat constipation. A medication injection component 2 is connected to one side of the reservoir 1. The medication injection component 2 can easily add medication to the reservoir 1, providing sufficient and clean medication reserves for subsequent medication, ensuring the continuity and stability of medication operation. A handrail component 3 is provided at one end of the reservoir 1, which can facilitate hand-held medication administration by the user and improve the medication effect. A rotating cylinder 4 is provided at the other end of the reservoir 1, and a limit insertion component 5 is slidably provided on the outer wall of the rotating cylinder 4.

[0021] One end of the rotating cylinder 4 is fixedly connected to a spiral rotating component 6. The limiting insertion component 5 facilitates insertion of the device into the patient's body while simultaneously housing the spiral rotating component 6. This prevents the spiral structure within the component from scraping the rectal mucosa and causing intestinal damage during insertion, reducing the patient's distending pain and discomfort. When insertion is obstructed, the user can release the limiting insertion component 5 from the rotating cylinder 4 and rotate the spiral rotating component 6 to break up hardened stool in the rectum, creating a smooth drug delivery channel. This allows the device to continue penetrating to the target drug delivery location. (The text also mentions a reservoir, but this seems unrelated to the main topic.) A pushing component 7 is slidably installed inside the 11, and the pushing component 7 is respectively installed in the armrest component 3 and the rotating cylinder 4. The first drug delivery component 8 is connected to one side of the liquid storage chamber 11, and the first drug delivery component 8 is installed in the spiral rotating component 6 and the pushing component 7. During the process of breaking down the dry and hardened feces, the drug in the liquid storage chamber 11 is sprayed out through the first drug delivery component 8 by squeezing the pushing component 7, which facilitates the softening of the dry and hardened feces that is being broken down, reduces the rotational resistance of the spiral rotating component 6, alleviates the patient's bloating and discomfort, and allows the drug to penetrate into the gaps of the feces and the surrounding rectal mucosa in advance, thereby improving the drug delivery effect.

[0022] In use, the medication is injected into the reservoir 11 through the injection component 2 and then sealed to facilitate medication addition to the reservoir 1. Afterwards, the air in the reservoir 11 is expelled by pressing the push component 7. Then, the limiting insertion component 5 is slowly inserted into the patient's anus. If insertion is obstructed, the user rotates the limiting insertion component 5 to release it from the obstruction of the reservoir 1. Rotating the reservoir 1 then causes the spiral rotating component 6 to rotate synchronously and extend the limiting insertion component 5, facilitating the breaking up of hardened stool obstructing the rectum and creating a clear drug delivery channel. Compared to existing technologies… This technique avoids damage to the intestinal mucosa caused by rigid insertion, reduces resistance during device advancement, and alleviates the patient's bloating and discomfort. Simultaneously, while rotating the reservoir 1, the user presses the pushing component 7, causing the pushing component 7 to spray the medication in the reservoir 11 through the first drug delivery component 8. This facilitates the simultaneous penetration and softening of the breaking-down feces by the medication. Compared to existing technologies, this technique avoids the medication being heavily absorbed and blocked by unbroken, hardened feces, improving the effective utilization rate of the medication. It also enhances the clearing effect of the spiral breaking mechanism and accelerates the device's advancement to the target drug delivery location.

[0023] When the reservoir 1 moves back to fit against one side of the limiting insertion component 5, the limiting insertion component 5 is slowly pushed so that the drug delivery device moves a short distance inside the patient's anus. Then the reservoir 1 is rotated again, causing the spiral rotating component 6 to rotate synchronously and extend out of the limiting insertion component 5. The drug is then sprayed out synchronously through the first drug delivery component 8. This cycle continues until the drug delivery position in the rectum is reached.

[0024] If the patient's stool is severely dry, after the first drug delivery component 8 sprays out the drug, wait for the drug to fully penetrate for a short period of time. When the dry stool softens and the overall hardness of the stool decreases, then push the limiting insertion component 5 to move. This will reduce the resistance when the device is pushed forward, avoid the hard push causing scratch damage to the rectal mucosa, and ensure that the device is smoothly inserted into the target drug delivery position.

[0025] The outer wall of the pushing component 7 is provided with an ejection component 9, which is slidably connected to the rotating cylinder 4. One end of the first drug delivery component 8 is connected to several second drug delivery components 10.

[0026] When the user pushes the limiting insertion component 5 and the rotating cylinder 4 to the drug delivery position in the rectum, the user rotates the pushing component 7 to make several ejection components 9 slide out from the rotating cylinder 4, so that the second drug delivery component 10 fits against the rectal wall. Then, by pressing the pushing component 7, the remaining drug in the reservoir 11 is sprayed out through the second drug delivery component 10. This facilitates the direct and even application of the drug to the rectal mucosa for precise drug delivery, avoiding the obstruction and interference of feces on the drug. Compared with the existing technology, it can improve the contact area and absorption efficiency between the drug and the intestinal mucosa, give full play to the drug efficacy, reduce drug waste, and reduce patient discomfort during the drug delivery process.

[0027] like Figures 2-3 As shown, the drug injection assembly 2 includes a drug injection tube 21 connected to one side of the liquid storage cylinder 1, the liquid storage chamber 11 is connected to the drug injection tube 21, and a sealing cap 22 is threaded to one end of the drug injection tube 21.

[0028] like Figure 2 and Figure 8 As shown, the handrail assembly 3 includes a threaded seat 32 that is threaded to one end of the liquid storage cylinder 1. A fixing plate 31 is fixedly connected to one side of the threaded seat 32, and the fixing plate 31 is in contact with one side of the liquid storage cylinder 1.

[0029] like Figures 1-9 As shown, the limiting insertion component 5 includes a sliding sleeve 51 slidably connected to the outer wall of the rotating cylinder 4. One end of the sliding sleeve 51 is set as a semi-circle, which facilitates the smooth and stable insertion of the device into the patient's anus, avoids sharp edges scratching the perianal and rectal mucosa, and reduces the resistance and discomfort of the patient during insertion. One end of the sliding sleeve 51 is threadedly connected to a threaded sleeve 52. Before the drug delivery device is inserted, one side of the threaded sleeve 52 is attached to the liquid storage cylinder 1, which facilitates the pre-fixation of the liquid storage cylinder 1 and the limiting insertion component 5, ensuring that the spiral rotating component 6 is stably housed in the limiting insertion component 5, and preventing the spiral rotating component 6 from accidentally protruding due to relative shaking of the components during insertion, thus ensuring the safety and smoothness of device insertion. A positioning sleeve 53 is fixedly connected inside the sliding sleeve 51, and the sliding sleeve 51 is evenly provided with several through grooves 54.

[0030] like Figures 3-4 and Figures 9-10 As shown, the spiral rotating assembly 6 includes a conical rod 61 fixedly connected to one end of the rotating cylinder 4. A conical spiral blade 62 is fixedly connected to the outer wall of the conical rod 61. By setting the conical spiral blade 62, it is convenient to efficiently break up the dry and blocked feces in the rectum. At the same time, the propulsive force of the spiral rotation assists the device to smoothly penetrate into the intestine, reduce the propulsion resistance, and avoid damage to the rectal mucosa caused by hard propulsion. The conical rod 61 is slidably connected to the positioning sleeve 53. One end of the sliding sleeve 51 is provided with a storage groove. With the setting of the positioning sleeve 53, the conical spiral blade 62 can be conveniently stored.

[0031] like Figures 2-3 , Figures 5-8 and Figure 10As shown, the pushing component 7 includes a slide rod 71 slidably connected to the threaded seat 32. The slide rod 71 is slidably connected to the inner wall of the liquid storage cylinder 1. A push rod 72 is fixedly connected to one end of the slide rod 71. A limit rod 73 is slidably connected to the outer wall of the push rod 72. A threaded rod 74 is fixedly connected to one end of the limit rod 73, and the other end of the threaded rod 74 is rotatably connected to the inner wall of the rotating cylinder 4. A pressure plate 75 is fixedly connected to one end of the slide rod 71. The pressure plate 75 works in conjunction with the fixing plate 31 to facilitate precise force application when the user holds the device. The sliding rod 71 is used to stably drive the piston 76 to advance the medicine in the reservoir 11, improving the controllability and convenience of the drug administration operation. The piston 76 is rotatably connected to the outer wall of the sliding rod 71. The piston 76 is rotatably connected to the sliding rod 71 through a sealed bearing. This allows the piston 76 to remain stationary and tightly fit against the inner wall of the reservoir 11 when the sliding rod 71 rotates to drive the ejector assembly 9. This avoids drug leakage and does not affect the unfolding of the ejector assembly 9 and subsequent accurate drug administration. The sealed bearing is existing technology and will not be described in detail here.

[0032] like Figures 3-4 and Figures 6-10 As shown, the first drug delivery assembly 8 includes several first outlet pipes 81 connected to one side of the liquid storage cylinder 1. The first outlet pipes 81 are connected to the liquid storage chamber 11. One end of the first outlet pipe 81 is connected to a first corrugated pipe 82, and one end of the first corrugated pipe 82 is connected to a first branch pipe 83. A flexible hose 84 is connected to one side of the first branch pipe 83. The flexible hose 84 is designed to accommodate the relative movements of the internal components, such as rotation and sliding, and to prevent the pipeline from being pulled, broken, twisted, or blocked due to rigid connections. This ensures that the drug can be stably and smoothly delivered to the subsequent spray. The structure includes a second liquid outlet pipe 85 fixedly connected inside the push rod 72, and several hoses 84 connected at one end to the second liquid outlet pipe 85. A first solenoid valve 86 is installed on the second liquid outlet pipe 85. One end of the second liquid outlet pipe 85 is connected to a second corrugated pipe 87, and the other end of the second corrugated pipe 87 is connected to a third liquid outlet pipe 88. The third liquid outlet pipe 88 is fixedly connected to the limit rod 73, the threaded rod 74, and the rotating cylinder 4. Several first spray pipes 89 are evenly arranged inside the conical spiral blade 62, and the first spray pipes 89 are connected to the third liquid outlet pipe 88.

[0033] In use, the medication is injected into the reservoir 11 through the injection tube 21. Then, the sealing cap 22 is rotated to seal the injection tube 21, facilitating the addition of medication to the reservoir 1. Afterward, by pressing and pushing the component 7, the air in the reservoir 11 is expelled through the first administration component 8 and the second administration component 10, while the medication enters the first administration component 8 and the second administration component 10. This facilitates the pre-filling of the administration tubing, preventing residual air in the tubing from causing discontinuous medication spraying during subsequent administration. It also reduces the risk of feces entering the first administration component 8 and the second administration component 10 during the insertion of the medication device, which could cause tubing blockage and affect the normal delivery and accurate administration of the medication. Subsequently, the user pushes the reservoir 1 to drive the sliding sleeve 51 and slowly insert it into the patient's anus.

[0034] When the device is obstructed during insertion, the user rotates the threaded sleeve 52 to release it from contact with the reservoir 1, thus removing its restriction on the reservoir 1. The user then holds the outer wall of the sliding sleeve 51 to prevent it from rotating, while simultaneously rotating the reservoir 1. This causes the rotating cylinder 4, the conical rod 61, and the conical spiral blade 62 to rotate synchronously and extend out of the positioning sleeve 53. This facilitates the breaking up of dry, hardened stool in the rectum and opens a clear channel for drug delivery. Compared to existing technologies, this avoids damage to the intestinal mucosa caused by forced insertion, reduces resistance during device delivery, and alleviates the patient's bloating and discomfort.

[0035] Simultaneously, during the rotation of the storage cylinder 1, the controller opens the first solenoid valve 86 while the second solenoid valve 101 remains closed. The user pushes the pressure plate 75, causing the slide rod 71, piston 76, and push rod 72 to move. This causes the push rod 72 to slide within the limit rod 73. Simultaneously, the piston 76 compresses the medication within the storage chamber 11, allowing it to pass through the first outlet pipe 81, the first corrugated pipe 82, the first branch pipe 83, the hose 84, the second outlet pipe 85, the first solenoid valve 86, and the second corrugated pipe 87 into the third outlet pipe 88. The medication is then sprayed out through several first spray pipes 89, facilitating simultaneous penetration and softening of the breaking-up feces. Compared to existing technologies, this avoids the medication being heavily absorbed and blocked by unbroken, dried feces, improving the effective utilization rate of the medication. It also enhances the clearing effect of the spiral crushing mechanism, accelerating the device's progress to the target drug delivery location.

[0036] When the reservoir 1 rotates and moves back to fit against one side of the threaded sleeve 52, the sliding sleeve 51 is slowly pushed until the conical spiral blade 62 fits against the inner wall of the positioning sleeve 53, so that the drug delivery device moves a short distance inside the patient's anus. Then the reservoir 1 is rotated again, causing the conical spiral blade 62 to rotate synchronously and extend out of the positioning sleeve 53, and the drug is sprayed out synchronously through the first drug delivery component 8. This cycle continues until the drug delivery position in the rectum is reached.

[0037] If the patient's stool is severely dry, after the first drug delivery component 8 sprays out the drug, wait for the drug to fully penetrate for a short period of time. When the dry stool softens and the overall hardness of the stool decreases, then push the sliding sleeve 51 to move. This will help reduce the resistance when the device is pushed forward, avoid scratching and damaging the rectal mucosa due to hard pushing, and ensure that the device is smoothly pushed into the target drug delivery position.

[0038] To address the technical problem of medication being easily blocked or absorbed by feces during administration in constipation medication delivery devices, resulting in ineffective medication loss and reduced treatment efficiency, such as... Figures 2-3 , Figures 5-7 and Figure 10 As shown, the following preferred technical solutions are provided: like Figure 3 , Figure 5 and Figure 10 As shown, the ejector assembly 9 includes a threaded post 91 threaded to the outer wall of the threaded rod 74. Several inclined grooves 92 are evenly provided on the outer wall of the threaded post 91. A slider 93 is slidably connected in the inclined grooves 92. A push block 94 is fixedly connected to one side of the slider 93. The push block 94 is slidably connected to the rotating cylinder 4.

[0039] like Figure 3 , Figures 5-7 and Figure 10 As shown, the second drug delivery assembly 10 includes a second solenoid valve 101 connected to one end of the first branch pipe 83, and the other end of the second solenoid valve 101 connected to a first drain pipe 102. One end of the first drain pipe 102 is connected to a third corrugated pipe 103, and the other end of the third corrugated pipe 103 is connected to a second drain pipe 104. One end of the second drain pipe 104 is connected to a fourth corrugated pipe 105, and the other end of the fourth corrugated pipe 105 is connected to a second branch pipe 106. The drug delivery assembly 10 passes through the first corrugated pipe 82, the second corrugated pipe 87, and the third corrugated pipe 104. The arrangement of the third and fourth corrugated pipes 105 facilitates the movement of various components inside the device, preventing the pipelines of the first drug delivery component 8 and the second drug delivery component 10 from being pulled, twisted or squeezed and damaged due to rigid connection, ensuring that the drug can still be stably and smoothly delivered to each spray structure during complex movement. The second branch pipe 106 is fixedly connected to the push block 94. Several second spray pipes 107 are connected to one side of the second branch pipe 106. One end of the second spray pipe 107 is connected to the liquid outlet plate 108. Several grooves are evenly opened on the outer wall of the rotating cylinder 4.

[0040] During the insertion of the device into the patient's body, the dispensing tray 108 is located in the groove, which facilitates the storage of the dispensing tray 108 and prevents it from scraping against the perianal and rectal mucosa during insertion, reducing the insertion resistance of the device and alleviating the patient's discomfort. At the same time, the width of the through groove 54 is greater than the diameter of the dispensing tray 108, which facilitates the smooth passage of the dispensing tray 108 through the through groove 54 and its unfolding and conforming to the inner wall of the rectum when the ejector component 9 drives the dispensing tray 108 out of the rotating cylinder 4, ensuring the smooth implementation of subsequent precise drug delivery actions. Several dispensing holes 109 are opened through one side of the dispensing tray 108. Several limiting sleeves 110 and fixing seats 111 are fixedly connected to the inner wall of the rotating cylinder 4. The first dispensing pipe 102 is slidably connected to the limiting sleeves 110. The setting of the limiting sleeves 110 facilitates the guidance and limiting of the first dispensing pipe 102, preventing it from deviating, twisting or getting stuck when moving inside the device, and ensuring the smoothness of the drug delivery pipeline. The second dispensing pipe 104 is fixedly connected to the fixing seat 111.

[0041] The dispensing tray 108 has an arc-shaped surface 20 on one side. The arc-shaped surface 20 facilitates close contact with the inner wall of the rectum, increases the contact area between the drug and the intestinal mucosa to improve the uniformity of drug administration, and avoids the right-angle edge from scratching the rectal mucosa, further reducing the patient's discomfort when administering the drug.

[0042] When the user pushes the limiting insertion component 5 and the rotating cylinder 4 to the drug administration position in the rectum, the user holds the outer wall of the sliding sleeve 51 and rotates the liquid storage cylinder 1, causing the rotating cylinder 4 to rotate synchronously, so that the position of the liquid dispensing plate 108 corresponds to the position of the through groove 54. Then, the user holds the liquid storage cylinder 1 and rotates the pressure plate 75, causing the slide rod 71 to drive the push rod 72, the limiting rod 73 and the threaded rod 74 to rotate synchronously. Through the threaded engagement between the threaded column 91 and the threaded rod 74, the threaded column 91 moves, pushing the slider 93 through the inclined groove 92, causing several push blocks 94 to slide out from the rotating cylinder 4, causing the liquid dispensing plate 108 to fit against the inner wall of the rectum. Then, the controller opens the second solenoid valve 101, while the first solenoid valve 86 is in the closed state. By pushing the pressure plate 75, the piston 76 squeezes the medicine in the storage chamber 11 again, so that the remaining medicine enters the liquid outlet plate 108 through the first outlet pipe 81, the first corrugated pipe 82, the first branch pipe 83, the second solenoid valve 101, the first drain pipe 102, the third corrugated pipe 103, the second drain pipe 104, the fourth corrugated pipe 105, the second branch pipe 106, and the second spray pipe 107, and is sprayed out through several outlet holes 109. This allows the medicine to be directly and evenly applied to the rectal mucosa for precise administration, avoiding the obstruction and interference of feces on the medicine. Compared with the existing technology, it can improve the contact area and absorption efficiency between the medicine and the intestinal mucosa, give full play to the efficacy of the medicine, reduce the ineffective loss of the medicine, and reduce the patient's discomfort during the administration process.
