Detailed Embodiments

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0022] The applicant believes that when using a traditional enema device for drug delivery, it is difficult to accurately control the dose and flow rate of the drug, which easily leads to uneven drug distribution and affects the treatment effect. Moreover, due to the slow drug delivery process, some drugs will be unevenly mixed and deposited, affecting the drug efficacy.

[0023] Therefore, the applicant designs a drug delivery and retrieval device for the treatment of ulcerative colitis. Through the provided drug retrieval and delivery assembly, the drug delivery speed can be continuously and autonomously controlled during the drug delivery process, and the drug can be mixed again at any time during the drug delivery process to ensure that the drug is evenly pushed into the affected area.

[0024] The drug-taking and drug-administering device for the treatment of ulcerative colitis involved in the present invention mainly includes a drug-carrying cylinder 1, a drug-taking and drug-administering component, and a diversion tube 3. Among them, the drug-carrying cylinder 1 is hollow and has a predetermined working size and a carrying space, and can perform corresponding carrying and connection limiting operations. The drug-taking and drug-administering component is movably connected to the drug-carrying cylinder 1 and can perform movable adjustment operations within a predetermined range along the inner wall surface of the drug-carrying cylinder 1; and is provided with multiple connecting cylinders 2, which can perform corresponding state adjustments during operations. The diversion tube 3 is connected to the drug-carrying cylinder 1, has a predetermined working length, and both ends are open, and can perform corresponding drainage operations. During the later operation process, through the movable adjustment of the drug-taking and drug-administering component, corresponding quantitative drug-taking and drug-administering are realized, and the flow rate and dose of drug administration can be controlled at any time during drug administration. That is, the drug-taking dose is controlled by controlling the working position of the multiple connecting cylinders 2, and the dose and flow rate of drug administration are controlled by the moving speed of the multiple connecting cylinders 2.

[0025] The drug-taking and drug-administering component includes a movable adjustment handle 4, a stirring disk 5, and multiple connecting cylinders 2; the multiple connecting cylinders 2 are hollow and have a predetermined working size, are movably arranged in the hollow chamber of the drug-carrying cylinder 1, and are provided with corresponding limiting through holes, and can perform corresponding limiting and connection operations; the stirring disk 5 is connected to the multiple connecting cylinders 2 through the movable adjustment handle 4, has a predetermined working size, and can perform rotational adjustment operations within a predetermined range; the movable adjustment handle 4 passes through the multiple connecting cylinders 2 and extends to a predetermined distance outside the working position of the multiple connecting cylinders 2. During the later operation process, by adjusting the working position of the movable adjustment handle 4, the whole stirring disk 5 is driven to perform corresponding working position adjustments, and the stirring disk 5 can be driven to rotate by rotating the movable adjustment handle 4, and then the drugs placed in the drug-carrying cylinder 1 can be mixed and stirred to mix the liquid medicine evenly and avoid the phenomenon of liquid medicine taking the opportunity. The whole multiple connecting cylinders 2 can also be driven to perform corresponding working position adjustments by adjusting different working positions of the movable adjustment handle 4, and then corresponding drug administration operations can be realized.

[0026] The inner wall surface of the multi-layer connection cylinder 2 has a predetermined working thickness, and a corresponding storage groove is provided on the working surface; the overall working size of the provided storage groove is adapted to the overall working size of the stirring disc 5, and the stirring disc 5 can be stored in the storage groove provided in the multi-layer connection cylinder 2. During the later operation process, when drug administration operation is required, the stirring disc 5 is stored in the storage groove. At this time, the working surface of the multi-layer connection cylinder 2 is flat, so that the liquid medicine can be completely pushed out during drug administration operation. When stirring operation is required, only need to push the movable adjustment handle 4 forward in the operation direction, drive the stirring disc 5 to be pushed out from the provided storage groove, and then rotate the movable adjustment handle 4 to drive the stirring disc 5 to rotate correspondingly, so as to mix and stir the liquid medicine placed in the medicine-carrying cylinder 1, ensuring that the liquid medicine is always in a uniform state during the drug administration process. At the same time, the liquid medicine can also be secondarily mixed and stirred in the medicine-carrying cylinder 1 after the medicine-taking operation is completed, and then the liquid medicine is pushed, ensuring that the liquid medicine is always in a uniform state.

[0027] The multi-layer connection cylinder 2 is threadedly connected to the medicine-carrying cylinder 1, and a clamping groove is provided on the inner wall surface of the multi-layer connection cylinder 2 in the operation direction, which can perform corresponding limit clamping operation on the adjustment handle. The movable adjustment handle 4 is provided with a corresponding clamping block 6. The clamping block 6 is placed on the working surface of the movable adjustment handle 4 and can follow the movable adjustment handle 4 to adjust the operation position correspondingly. In a further preferred embodiment, the clamping block 6 is placed in the hollow bearing space of the multi-layer connection cylinder 2. During the later operation process, when the movable adjustment handle 4 drives the clamping block 6 to be pushed forward in the operation direction, the clamping block 6 will be pushed into the provided clamping groove, and at this time the stirring disc 5 is pushed out of the storage groove.

[0028] The inner wall surface of the multi-layer connection cylinder 2 away from the provided storage groove is provided with a connection clamping groove. The overall working size of the provided connection clamping groove is adapted to the overall working size of the clamping block 6 provided on the movable adjustment handle 4, and the operation state and position of the movable adjustment handle 4 can be correspondingly limited and adjusted through the provided connection clamping groove.

[0029] In a further preferred embodiment, the clamping block 6 includes two parts, namely a clamping ring and a rotating ring. The overall working size of the clamping ring is adapted to the working size of the provided clamping groove, and a plurality of alignment blocks are provided on the working surface of the clamping ring. The rotating ring is slidably connected to the clamping ring and can perform all-round rotation adjustment operations. The rotating ring is fixedly connected to the movable adjustment handle 4 and can perform corresponding rotation following the rotation adjustment of the movable adjustment handle. Alignment grooves adapted to the alignment blocks are provided in both the clamping groove and the connection clamping groove. During subsequent operations, by pushing the movable adjustment handle 4 forward and backward in its working direction, the entire clamping block 6 is driven to move to a corresponding working position, and the alignment blocks provided on the surface of the clamping block 6 are inserted into the provided alignment grooves. When the clamping block 6 is inserted into the clamping groove, the stirring disc 5 is pushed out of the storage groove. By rotating the movable adjustment handle 4, since the rotating ring is rotatably connected to the clamping ring, the movable adjustment handle 4 can be flexibly rotated and adjusted in all directions, and then the entire stirring disc 5 can be driven to perform corresponding all-round rotation adjustment to perform corresponding liquid medicine stirring operations. When the clamping block 6 is inserted into the connection clamping groove, the stirring disc 5 is received into the provided storage groove. Since the size of the provided storage groove is adapted to the stirring disc 5, when the stirring disc 5 is received into the storage groove, the stirring disc 5 is clamped. Since the stirring disc 5 is fixedly connected to the movable adjustment handle 4, when the movable adjustment handle 4 is rotated again, the stirring disc 5 will drive the multi-layer connection cylinder 2 to perform corresponding rotation. Since the multi-layer connection cylinder 2 is threadedly connected to the medicine-carrying cylinder 1, the rotation of the entire multi-layer connection cylinder 2 can cause the multi-layer connection cylinder 2 to move forward or backward along the wall surface of the medicine-carrying cylinder 1 accordingly, thereby realizing corresponding drug delivery operations. By controlling the rotation speed of the movable adjustment handle 4, the purpose of controlling the drug delivery amount and speed can be achieved.

[0030] The diversion tube 3 has a predetermined working length and flexibility, and a lubricating insertion head 7 is connected to one end; the lubricating insertion head 7 is provided with a plurality of liquid outlet through holes, and the plurality of liquid outlet through holes are arranged in a staggered manner; the lubricating insertion head 7 has a predetermined working length and hardness and is communicated with the diversion tube 3. During subsequent operations, by adjusting the working position of the multi-layer connection cylinder 2, the liquid medicine can be pushed out through the diversion tube 3, and the lubricating insertion head can apply corresponding lubricant to reduce the discomfort of the patient during use.

[0031] The medicine-loading cylinder 1 is connected with a medicine-taking catheter 8. The medicine-taking catheter 8 has a predetermined working length and flexibility, and there is a predetermined working distance between it and the diversion tube 3. One end of the medicine-taking catheter 8 is movably connected with a rubber sealing plug 9. The rubber sealing plug 9 has a predetermined working size and flexibility and is connected to the medicine-taking catheter 8 through a limit ring 10. During the later use process, the provided rubber sealing plug 9 needs to be removed, and then the liquid medicine is pushed into the medicine-loading cylinder 1 through the medicine-taking catheter 8 to complete the corresponding medicine-taking operation. In a further preferred embodiment, the lowest working surface of the rubber sealing plug 9 is flush with the working surface of the medicine-loading cylinder 1, so that the liquid medicine will not enter the medicine-taking catheter 8 during the later use process.

[0032] A corresponding sealing ring is provided at the connection between the multi-layer connecting cylinder 2 and the medicine-loading cylinder 1. The sealing ring can adjust the corresponding working position according to the movement adjustment of the multi-layer connecting cylinder 2. When performing the medicine-taking operation, the working position of the multi-layer connecting cylinder 2 can be adjusted first to determine the dosage of the medicine-taking. Then, as long as the liquid medicine is pushed into the medicine-loading cylinder 1 until it is full, the quantitative medicine-taking operation can be completed quickly and conveniently. During the actual operation process, the liquid medicine can be pushed into the medicine-taking catheter 8 through a syringe. Compared with the traditional medicine-taking method of screwing and pouring, since the medicine-loading cylinder 1 is in a fully enclosed state in this application, the phenomenon of secondary pollution of the medicine during the medicine-taking process can be effectively avoided, and the phenomenon of secondary infection of the medicine during the administration process can also be effectively avoided.

[0033] In a further preferred embodiment, the medicine-loading cylinder 1 is made of a transparent material, and corresponding scales are provided on the surface of the working surface, which is convenient for observation during the administration process and adjustment of the medicine-taking measurement.

[0034] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
