Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anorectal drug delivery device. Background Technology

[0002] Anorectal diseases are common and frequently occurring, causing considerable discomfort and distress to patients. Drug therapy is one of the important methods for treating anorectal diseases, and rectal drug delivery devices, as crucial tools for delivering medication into the rectum, play a key role in clinical treatment and patient self-care. With the development of medical technology and people's increasing demands for treatment effectiveness, higher expectations are being placed on the performance and function of rectal drug delivery devices.

[0003] Currently, most rectal medication administration devices on the market have relatively simple structures. They typically work by inserting a cartridge into the rectum and pushing a plunger to expel the medication. However, this method has significant limitations. Due to the lack of effective positioning methods, medical personnel can only rely on experience to roughly determine the administration location, making it difficult to precisely pinpoint the specific lesion. This results in the medication not being fully applied to the affected area, affecting treatment efficacy and potentially wasting medication. Furthermore, this indiscriminate administration method may cause uneven drug distribution, unnecessarily irritating other healthy tissues in the rectum and increasing patient discomfort. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rectal drug delivery device, which solves the technical problems of traditional rectal drug delivery devices that are difficult to accurately locate the lesion site, resulting in the drug not being able to fully act on the diseased area, easily causing drug waste, and are not easy to control the rotation of the ball head.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A rectal medication applicator, comprising: an outer cylinder; a medication cartridge, rotatably and slidably disposed within the outer cylinder, the medication cartridge being used to store therapeutic drugs; a ball head, rotatably disposed within the outer cylinder, with the ball head located at the end of the outer cylinder furthest from the medication cartridge; a medication outlet, opened within the ball head, communicating with the medication cartridge, the medication outlet being used to discharge the therapeutic drugs from the medication cartridge; and a camera, mounted on the ball head, located at the end of the ball head furthest from the medication cartridge, the camera being used to observe the location of lesions in the rectum. Both the outer cylinder and the medication cartridge can be made of medical-grade transparent plastic material, facilitating direct viewing of the remaining medication. The camera needs to be connected to an external observation device, which can be a portable display screen, tablet computer, etc. The connection method can be a wired connection, and the wiring method can be to create a wire groove on the inner wall of the outer cylinder to hide the wires, ensuring both the aesthetics of the overall structure and preventing damage to the wires during use.

The connecting rod 7 is used by the cartridge 2 to control the rotation of the ball head 3. By adopting the above technical solution, the effect of flexibly controlling the rotation of the ball head 3 is achieved. The connecting rod 7 connects the ball head 3 and the cartridge 2. When the cartridge 2 rotates and slides, the connecting rod 7 transmits power, causing the ball head 3 to rotate flexibly as needed, changing the direction of the ball head 3 to meet the needs of drug administration and observation at different positions.

[0027] See Figure 4 This application also includes two connectors 6, each connected to one end of the connecting rod 7. The connectors 6 are rotatably connected to the connecting rod 7 and are used to connect the connecting rod 7 to the ball head 3 and the cartridge 2. By adopting the above technical solution, a stable connection and flexible rotation are achieved. The two connectors 6, connected to both ends of the connecting rod 7, establish a stable connection between the connecting rod 7 and the ball head 3 and the cartridge 2. Simultaneously, their rotatable connection to the connecting rod 7 allows the ball head 3 to rotate flexibly under the influence of the connecting rod 7, adapting to complex operational requirements.

[0028] See Figure 3 This application also includes two stop blocks 101, each stably connected inside the outer cylinder 1. The stop blocks 101 are annular, and their inner diameter matches the outer diameter of the cartridge 2. The stop blocks 101 are used to limit the position of the cartridge 2 within the outer cylinder 1. By adopting the above technical solution, the position of the cartridge 2 is effectively limited. The two annular stop blocks 101, fixed inside the outer cylinder 1 with their inner diameters matching the outer diameter of the cartridge 2, effectively restrict the position of the cartridge 2 within the outer cylinder 1, preventing the cartridge 2 from shaking or shifting during operation, thus ensuring the stability and reliability of the entire device.

[0029] See Figure 3 This application also includes a limiting block 201, stably connected to the periphery of the cartridge 2.

[0032] See Figure 4 In this application, the position of the connecting piece 6 on the cartridge 2 is offset from the axis of the outer cylinder 1. By adopting the above technical solution, the rotational flexibility of the ball head 3 is enhanced; the position of the connecting piece 6 on the cartridge 2 is offset from the axis of the outer cylinder 1, and when the cartridge 2 rotates or slides, a more effective torque is generated through the connecting rod 7, thereby driving the ball head 3 to rotate more flexibly, which facilitates more comprehensive observation and precise drug delivery to different positions.

[0033] The working principle of this application is as follows: During use, the outer cylinder 1 is first slowly inserted into the patient's anus, and the medicine cylinder 2 is rotated and slidably set inside the outer cylinder 1. At this time, the medicine cylinder 2 stores the therapeutic drug. The operator rotates or pulls the medicine cylinder 2, and the connecting piece 6 on the medicine cylinder 2, which is off the axis of the outer cylinder 1, drives the ball head 3 to rotate through the connecting rod 7. The center point of the ball head 3 is on the axis of the outer cylinder 1, making the rotation more stable. Since the ball head 3 and the medicine cylinder 2 are connected through the connecting piece 6 and the connecting rod 7, the direction can be flexibly changed. The camera 4 installed on the ball head 3 is located at the end away from the medicine cylinder 2. In conjunction with the external observation equipment, the location of the lesion in the anorectal region is clearly presented. After the location of the lesion is determined, the piston rod 8 inside the medicine cylinder 2 is pushed. The piston rod 8 pushes the therapeutic drug in the medicine cylinder 2. The drug is discharged from the outlet 301 opened in the ball head 3 through the connecting hose 5, realizing precise drug delivery. During this process, the two annular blocks 101 inside the outer cylinder 1 cooperate with the limiting block 201 on the periphery of the medicine cylinder 2 to limit the position and sliding distance of the medicine cylinder 2, ensuring that the entire operation is stable and precise.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
