Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a highly efficient and rapid rectal drug delivery device. Background Technology

[0002] Rectal administration refers to the delivery of medication into the intestines through the anus. The medication is rapidly absorbed through the rectal mucosa and enters the systemic circulation to exert its therapeutic effect on systemic or local diseases. It is also an effective treatment for anorectal diseases. Rectal administration generally requires the assistance of anal delivery devices. However, currently available anorectal delivery devices often slip out after insertion into the patient's anus, causing secondary pain and further suffering. Moreover, the manual administration process is slow and time-consuming, causing prolonged patient discomfort and significant medication waste, thus affecting the effectiveness and efficiency of treatment. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a rationally designed, convenient, efficient, and rapid anorectal drug delivery device that eliminates the need for manual drug delivery and prevents slippage during the drug delivery process, thereby reducing user pain and improving treatment effectiveness and efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a fixing base and a medicine storage box, wherein the medicine storage box is fixed to one side of the upper sidewall of the fixing base; it further includes:

[0005] The clamping plates are two in number and are symmetrically arranged on both sides of the fixing base. The fixing base is equipped with a linkage mechanism that is connected to the two clamping plates.

[0006] The insert rods are of several kinds and are fixed equally and at equal intervals on the left and right sides of the clamping plate adjacent to the side wall of the fixed seat. The insert rods are movably inserted into the fixed seat.

[0007] The skateboard, wherein there are two skateboards, which are symmetrically slidably arranged in the grooves on the side wall of the fixed base;

[0008] Leg fixing plates, there are two leg fixing plates, and they are respectively set on the upper side of the skateboard. One side of the leg fixing plate is screwed to one side of the upper surface of the skateboard through a hinge seat.

[0009] Angle adjustment mechanism, there are two angle adjustment mechanisms, and they are respectively set on the other side of the lower side wall of the leg fixing plate, and the angle adjustment mechanism is set on the other side of the upper surface of the skateboard;

[0010] The drug delivery mechanism is located on one side wall of the drug storage box and is connected to the drug storage box.

[0011] The above technical solution involves placing the fixing seat on the desired bed board, then using a linkage mechanism to move the clamping plate until it contacts both sides of the bed board, thus positioning the fixing seat. The user lies on the bed board, and the sliding plate slides on the fixing seat according to the user's leg position until it reaches a suitable position. The user places both legs on the leg fixing plate, and the angle of the leg fixing plate is adjusted by an angle adjustment mechanism according to the user's leg length and comfort, thus positioning the user. Finally, the drug delivery mechanism performs the drug delivery operation.

[0012] As a further improvement of the present invention, the clamping plate is provided with a slot on one side wall adjacent to the fixing seat, and the inner top wall of the slot is arranged in the same plane as the lower side wall of the fixing seat.

[0013] With the above technical solution, when clamping, the slots on the clamping plate engage with both sides of the bed board, increasing the stability of the clamping plate during clamping.

[0014] As a further improvement of the present invention, elastic fixing straps are fixed on the upper surface of the leg fixing plate.

[0015] The above technical solution involves placing the user's legs on a leg fixation plate and then securing the legs with elastic bands.

[0016] As a further improvement of the present invention, a pad is fixed on the side wall of the fixed base away from the medicine storage box, and the upper side wall of the pad is inclined downward away from the fixed base.

[0017] With the above technical solution, the user's buttocks are placed on the pad during use, which improves the user's comfort.

[0018] As a further improvement of the present invention, the linkage mechanism includes:

[0019] The linkage gear is embedded in the center of the fixed base, and a linkage rod is inserted and fixed in the center of the linkage gear. The lower end of the linkage rod is screwed to the lower inner wall of the fixed base through a bearing.

[0020] The linkage rack consists of two racks, which are fixed one-to-one on the side wall of the clamping plate adjacent to the fixed base. The two linkage racks are staggered left and right, and are inserted into the fixed base and mesh with the linkage gear.

[0021] The plum blossom hand-tightener is embedded in a circular groove on the upper side wall of the fixed base. The plum blossom hand-tightener is fixedly connected to the top of the linkage rod. The upper surface of the plum blossom hand-tightener is set in the same plane as the upper side wall of the fixed base.

[0022] With the above technical solution, rotating the pendulum hand screw causes the linkage rod to rotate, which in turn drives the linkage gear to rotate. The linkage gear then moves the linkage racks on both sides away from the fixed seat. The fixed seat is then placed on the bed board, so that the clamping plate is located on both sides of the bed board. Then, rotating the pendulum hand screw in the opposite direction causes the linkage gear to rotate in the opposite direction through the linkage rod, thereby moving the linkage racks to one side of the fixed seat until the clamping plate is clamped on the bed board.

[0023] As a further improvement of the present invention, the linkage rack is fixed on the lower side wall of the side away from the clamping plate, and the limiting slider is slidably disposed in the groove on the bottom wall of the fixed seat.

[0024] Through the above technical solution, during the movement of the linkage rack, the limiting slider limits the linkage rack to a certain extent, preventing the linkage rack from moving out of the fixed seat.

[0025] As a further improvement of the present invention, the angle adjustment mechanism includes:

[0026] An adjusting seat is fixed on the upper surface of the slide plate. An internally threaded tube is screwed into the interior of the adjusting seat through a bearing. The upper end of the internally threaded tube is on the same plane as the top wall of the adjusting seat.

[0027] The adjusting motor is embedded and fixed on the inner bottom wall of the adjusting seat. The adjusting motor is connected to an external power source, and the output shaft of the adjusting motor is fixedly connected to the bottom end of the internal threaded tube.

[0028] The screw is threaded into an internally threaded tube. After the top end of the screw passes through the top end of the internally threaded tube, a sliding block is threaded onto it via a shaft. The sliding block is slidably disposed in a groove on the lower side wall of the leg fixing plate.

[0029] Using the above technical solution, the adjustment motor is started, which drives the internal threaded tube to rotate. Under the limit of the sliding block, the screw moves up and down. While the screw moves up and down, it drives the sliding block to slide in the groove on the lower side of the leg fixing plate. At this time, the leg fixing plate rotates with the hinge seat on its other end as the axis until it reaches the appropriate position.

[0030] As a further improvement of the present invention, the drug delivery mechanism includes:

[0031] The pump is fixed on the outer wall of one side of the medicine storage tank. The inlet of the pump is connected to the inside of the medicine storage tank through a pipe, and the outlet of the pump is connected to a flexible hose.

[0032] Mounting plate, which is located on the upper side of the fixed base, through which the flexible hose is inserted and fixed;

[0033] The administration tube is located on the side of the mounting plate away from the medicine storage tank. A threaded seat is screwed into the end of the administration tube adjacent to the mounting plate. The threaded seat is fixed to the mounting plate and fixedly connected to one end of the tubing.

[0034] The lead screw is embedded in one side of the fixed seat. The two ends of the lead screw are screwed to the two inner walls of the fixed seat through bearings. The lead screw nut is fixedly connected to one side of the lower side wall of the mounting plate through a support plate. The other side of the lower side wall of the mounting plate slides in the groove on the fixed seat through a guide rod.

[0035] The drive motor is embedded in one side of the fixed base, the drive motor is connected to an external power source, and the output shaft of the drive motor is fixedly connected to one end of the lead screw.

[0036] Using the above technical solution, the drive motor is started, which drives the lead screw to rotate. The lead screw moves the mounting plate through the lead screw nut and the support plate at its upper end. The mounting plate moves the medication tube to the side of the user. At the same time, the medication tube is inserted into the user's anus until it reaches the appropriate position. The drive motor is then turned off, and the pump is started. The pump sequentially pumps the liquid medicine into the tubing, the threaded seat, and the medication tube, and finally flows into the user's anus through the through hole on the medication tube.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] 1. When in use, this device can be positioned on the bed board, and after use, it can be removed for easy transfer to the location where it is needed, thus improving portability.
