Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a hemorrhoid medication device. Background Art

[0002] Hemorrhoids are a common condition in the anorectal area, manifesting as lumps formed by varicose veins around the anus. Depending on the location of the hemorrhoids, they can be categorized as internal, external, and mixed. Internal hemorrhoids, located inside the anus, are often accompanied by bleeding and, in severe cases, may produce pus and other secretions. More severe hemorrhoids are typically treated with topical medications, with existing routes of administration primarily involving suppositories or ointments administered via push-button delivery devices.

[0003] However, in actual treatment, especially for internal hemorrhoids, the presence of secretions such as tissue fluid, pus, and blood around the affected area can severely impact the effectiveness of medications. This can prevent topical ointments or suppositories from reaching the affected area, further impacting drug absorption and therapeutic efficacy, significantly reducing the effectiveness of treatment. Traditional drug delivery devices focus solely on drug delivery and fail to effectively remove these interfering secretions, preventing the drug from achieving its maximum effectiveness in a clean, suitable environment. Summary of the Invention

[0034] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of this application generally described and shown in the drawings herein can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application.

[0035] When administering medication, conventional hemorrhoid medication devices may produce tissue fluid, even secretions such as pus and blood, around hemorrhoids, especially internal hemorrhoids. Excessive secretion may dilute the concentration of the drug in the local lesion, preventing the topical ointment or suppository from fully contacting the affected area, reducing the intensity of the active ingredient and affecting absorption. Furthermore, multiple insertions are often required to avoid cleaning the affected area of ​​internal hemorrhoids, which undoubtedly increases the patient's discomfort. Failure to address these issues will not only affect the therapeutic effect of the drug, but may also prolong the treatment cycle, reduce patient compliance, and even increase the risk of secondary infection due to incomplete cleaning.

[0036] In response to this, the present application proposes a hemorrhoid medication device designed to address the issues of waste liquid and ointment mixing and inconvenient operation in the prior art. Through its structural design, the device integrates the functions of extracting waste liquid and extruding ointment. Specifically, the device primarily consists of an outer housing 2, which provides support and protection for the various functional components within the device. A partition is disposed within the housing 2, clearly dividing the interior space of the housing 2 into at least one medication chamber 9 for storing and extruding ointment, and a waste liquid chamber 10 for collecting and isolating waste liquid. This separation ensures that the ointment and waste liquid do not interfere with each other. The medication chamber 9 is used to hold the ointment to be applied, while the waste liquid chamber 10 is used to collect waste liquid secreted from the affected area. A piston 7 is a key movable component disposed within the housing 2. Its design enables it to move axially along the housing 2, thereby generating the desired pressure changes in the different chambers. A rotary switch 8 is disposed on the exterior of the housing 2, typically in a convenient location. Rotating the rotary switch 8 precisely controls the opening or closing of the entrance to the waste liquid chamber 10.

[0037] See also Figure 1 and Figure 2 The hemorrhoid medication device of this embodiment includes a housing 2, which serves as the outer frame and main load-bearing structure of the device. The housing 2 can be made of a variety of medical-grade materials, such as polypropylene, polyethylene, or ABS plastic, to ensure its biocompatibility and durability.

[0038] Inside the housing 2, a partition is provided to separate the interior space of the housing 2 into at least one medication chamber 9 and a waste liquid chamber 10. This partition can be a one-piece structure or assembled from multiple independent components. The partition physically separates the medication chamber 9 and the waste liquid chamber 10, effectively preventing the ointment and waste liquid from mixing within the device.

[0039] See also Figure 3 and Figure 4 The piston 7 is movably arranged in the shell 2, and its design enables it to reciprocate in the internal space of the shell 2. The piston 7 is usually made of elastic material, so that it can effectively generate a pressure difference during movement. When the piston 7 moves in one direction, such as pulling backward, it forms a negative pressure in the waste liquid chamber 10, thereby sucking external waste liquid into the waste liquid chamber 10; when the piston 7 moves in another direction, such as pushing forward, it forms a positive pressure in the medication chamber 9, thereby squeezing out the ointment in the medication chamber 9. The movement stroke and speed of the piston 7 can be adjusted according to actual needs to control the amount of liquid absorbed and the amount of ointment squeezed out. A certain gap is usually maintained between the piston 7 and the partition or a flexible connection is made to allow it to effectively transfer pressure between different chambers.

[0040] See also Figure 1 、 Figure 2 and Figure 3 The rotary switch 8 is provided on the housing 2, usually located outside the housing 2, for easy operation by the user. The rotary switch 8 can be a rotatable annular component, the interior or bottom of which is connected to a mechanical structure for controlling the entrance of the waste liquid chamber 10.

[0041] In some of the above embodiments of the present application, a hemorrhoid medication device is proposed, which aims to optimize the application method of the ointment and the collection efficiency of the waste liquid by providing an application head 110.

[0042] Among them, the applicator head 110 is arranged at one end of the shell 2, serving as an outlet for the ointment and an inlet for the waste liquid. Specifically, the applicator head 110 is designed as a hollow structure, and its internal space is connected to the drug delivery chamber 9, so that the ointment can be smoothly squeezed from the drug delivery chamber 9 to the inside of the applicator head 110. In addition, the surface of the applicator head 110 is provided with a plurality of drug outlet holes, which are used for the uniform discharge and application of the ointment. These drug outlet holes can be designed into different shapes, sizes and distributions according to actual needs to adapt to different drug delivery needs and the shape of the affected area. For example, the drug outlet holes can be arranged in a ring shape, a dot shape or a line shape to ensure that the ointment can be evenly applied to the affected area. The material of the applicator head 110 can be medical grade silicone or plastic to ensure its biocompatibility and easy cleaning.

[0043] In some preferred embodiments, the application head 110 can be designed to be conical or cylindrical to facilitate insertion and contact with the affected area. For example, the surface of the application head 110 can be designed to be smooth or have tiny bumps to reduce friction and improve the comfort of application.

[0044] In some of the aforementioned embodiments of the hemorrhoid medication delivery device, piston 7 is used to create positive pressure within medication chamber 9 to squeeze out the ointment. However, in actual operation, the direct action of piston 7 on the ointment may result in uneven ointment extrusion, affecting smooth ointment discharge and even causing wear on piston 7 or ointment residue. To address these issues, the present application further optimizes the ointment extrusion mechanism within medication chamber 9, proposing an improved medication chamber structure.

[0045] In this regard, the present application further proposes a hemorrhoid medication device, wherein a push plate 91 and a push plate slide 92 are provided in the medication cavity 9 , the piston 7 is used to push the push plate 91 , and the push plate 91 slides along the push plate slide 92 .

[0046] Among them, the push plate 91 refers to a movable structural member arranged inside the drug delivery chamber 9. Specifically, the push plate 91 is configured to fit tightly with the inner wall of the drug delivery chamber 9 to prevent the ointment from leaking from the side of the push plate 91. The push plate slide 92 refers to a guide structure arranged on the inner wall of the drug delivery chamber 9 or integrally formed with the drug delivery chamber 9, which is used to limit the movement trajectory of the push plate 91 and ensure that the push plate 91 can slide smoothly along a preset path under the push of the piston 7, thereby achieving stable extrusion of the ointment. The push plate slide 92 can be one or more grooves, protrusions or guide columns, and its purpose is to provide precise guidance for the push plate 91 to prevent it from tilting or getting stuck during movement.

[0047] In some preferred embodiments, the push plate 91 can be designed to be a circular or elliptical disc-shaped structure that matches the inner cross-sectional shape of the dosing chamber 9, and its outer edge can be provided with a sealing ring to further enhance the sealing with the inner wall of the dosing chamber 9 and prevent the ointment from flowing back. The push plate slide rail 92 can be specifically expressed as two or more raised guide rails extending axially on the inner wall of the dosing chamber 9, and the edge of the push plate 91 is correspondingly provided with grooves that cooperate with these guide rails. When the piston 7 moves forward, its front end contacts and applies thrust to the rear end of the push plate 91. Under the guidance of the guide rail, the push plate 91 slides forward smoothly to push out the ointment in the dosing chamber 9. In some embodiments of the present application, although the piston 7 can form a negative pressure in the waste liquid chamber 10 to absorb waste liquid, and form a positive pressure in the dosing chamber 9 to squeeze out the ointment, the movement stroke of the piston 7 is not easy to control, which may lead to unstable dosing amount or insufficient waste liquid absorption. In this regard, the present application provides an improved solution, namely, adding a push rod 1 connected to the piston 7, an air cushion mechanism 5 arranged in the shell 2, and a limit plate 4 arranged on the push rod 1. The limit plate 4 contacts the air cushion mechanism 5 when the push rod 1 moves, thereby more accurately controlling the movement of the piston 7 and improving the efficiency and accuracy of drug administration and waste liquid absorption.

[0048] The push rod 1 is a rod-shaped structure connected to the piston 7, used to transmit externally applied force and control the movement of the piston 7. The push rod 1 can be made of metal, plastic, or other sufficiently strong materials. The air cushion mechanism 5 is disposed within the housing 2 to provide cushioning and reaction force, thereby limiting the range of motion of the push rod 1.

[0049] In the present invention, the air cushion mechanism 5 effectively cushions the movement of the push rod 1, preventing the piston 7 from moving too quickly or too violently, thereby avoiding problems such as excessive or insufficient dosing and insufficient waste liquid extraction. The coordination of the stopper 4 and the air cushion mechanism 5 precisely controls the travel of the piston 7, ensuring consistent dosing and waste liquid extraction, thereby improving the stability and reliability of the drug delivery device.

[0050] In the above embodiment of the present application, the push rod 1 reciprocates, so that the piston 7 forms a negative pressure in the waste liquid chamber 10 to absorb the waste liquid, and forms a positive pressure in the drug delivery chamber 9 to squeeze out the ointment. However, in actual use, the rotary switch 8 may be accidentally touched, causing it to rotate unexpectedly, thereby affecting the effect of drug delivery or waste liquid absorption, and may even cause accidental leakage of the ointment. In this regard, the present application provides a protrusion on the push rod 1 and a groove on the rotary switch 8. The rotation of the rotary switch 8 is limited by the cooperation of the protrusion and the groove, thereby avoiding the occurrence of the above situation.

[0051] Among them, the locking device 3 includes a protrusion set on the push rod 1 and a groove set on the rotary switch 8. The position and number of the protrusion and the groove can be adjusted according to actual needs. There are also multiple options for the shape of the protrusion, such as hemispherical, cylindrical or prismatic, etc. The shape of the groove should match the shape of the protrusion to ensure that the protrusion can smoothly enter the groove and achieve locking.

[0052] In the solution of the present application, when the push rod 1 moves to a specific position, the protrusion on the push rod 1 will be aligned with the groove on the rotary switch 8 and cooperate with each other, thereby limiting the rotation of the rotary switch 8 to prevent it from being accidentally touched or rotated. Only when the push rod 1 moves to a specific position and the protrusion is separated from the groove, can the rotary switch 8 rotate freely, thereby realizing the selection of opening or closing the entrance of the waste liquid chamber 10.

[0053] As a preferred embodiment, the protrusion can be made of elastic material, such as rubber or elastic plastic. In this way, when the rotary switch 8 is subjected to external force, the protrusion can undergo elastic deformation, thereby playing a buffering role to prevent the rotary switch 8 or the push rod 1 from being damaged. At the same time, the elastic protrusion can also better cooperate with the groove to improve the reliability of the locking position.

[0054] In the above embodiment of the present application, the cooperation between the housing 2 and the piston 7 is the key to achieving drug administration and waste liquid extraction. However, if the piston 7 is in direct contact with the inner wall of the housing 2, long-term use may cause wear due to friction, affecting the sealing and service life of the device.

[0055] In this regard, the present application proposes an improved solution, namely, providing a slide groove on the side wall of the piston 7 and providing a slide rail 6 that cooperates with the slide groove on the inner wall of the housing 2. In this way, the direct friction between the piston 7 and the housing 2 can be reduced, and the durability and stability of the device can be improved.

[0056] The chute refers to a groove formed on the sidewall of the piston 7, and its shape and size can be adjusted according to actual needs. The slide rail 6 refers to a raised structure provided on the inner wall of the housing 2, whose shape and size match the chute, guiding the piston 7 to slide smoothly within the housing 2. As a preferred embodiment, the chute can be configured as an annular chute, and the slide rail 6 can be configured as an annular protrusion corresponding to the annular chute, thereby ensuring that the piston 7 maintains contact with the slide rail 6 during movement.

[0057] The solution of the present application solves the problem of insufficient control accuracy by connecting fan blades to the rotary switch 8 and using the rotation of the fan blades to accurately control the opening and closing of the entrance of the waste liquid chamber 10. Specifically, when it is necessary to open the entrance of a waste liquid chamber 10, it is only necessary to rotate the rotary switch 8 to rotate the corresponding fan blade to the open position; when it is necessary to close the entrance of a waste liquid chamber 10, it is only necessary to rotate the rotary switch 8 in the opposite direction to rotate the corresponding fan blade to the closed position.

[0058] In the solution of the present application, considering that directly exposing the entrance of the waste liquid chamber 10 to the outside may cause waste liquid backflow or contamination, a waste liquid absorption layer 101 is set at the entrance of the waste liquid chamber 10 to enhance the waste liquid absorption effect and prevent backflow.

[0059] The waste liquid absorbing layer 101 is a structure capable of absorbing and discharging waste liquid, and can be made of a variety of materials, such as absorbent cotton, sponge, non-woven fabric, etc. The shape and size of the waste liquid absorbing layer 101 can be adjusted according to the shape and size of the entrance of the waste liquid chamber 10 to ensure that it can completely cover the entrance and effectively absorb the waste liquid.

[0060] As a preferred embodiment, the waste liquid absorption layer 101 can adopt a multi-layer structure, for example, including a water-absorbing cotton layer and a water-isolating cotton layer disposed between the water-absorbing cotton layer and the waste liquid chamber 10. The water-absorbing cotton layer has good water absorption properties and can quickly absorb waste liquid; the water-isolating cotton layer has good water-isolating properties and can prevent the waste liquid absorbed by the water-absorbing cotton layer from leaking into the waste liquid chamber 10, thereby ensuring the waste liquid absorption effect and the hygiene of the device.

[0061] Furthermore, the waste liquid absorbing layer 101 can effectively absorb and fix the waste liquid, preventing the waste liquid from flowing or leaking inside the device, thereby keeping the drug delivery device clean and hygienic. In addition, the waste liquid absorbing layer 101 can also prevent bacteria in the waste liquid from growing, reducing the risk of infection.

[0062] As a preferred embodiment, the waste liquid absorbing layer 101 can be designed to be replaceable, so that users can replace it regularly to maintain its good liquid absorption effect and hygienic performance.

[0063] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
