Abstract
Description
Technical Field
[0001] This application belongs to the field of medical supplies technology, specifically relating to an enema bottle. Background Technology
[0002] Enema bottles are commonly used in proctology procedures as a medical device. Existing enema bottles typically have a fixed capacity, limiting the amount of enema solution they can hold. During continuous enema treatment, once a bottle is empty, medical staff must interrupt the procedure to replace it with a new one. This frequent replacement not only disrupts the treatment process and reduces efficiency, but also risks leakage due to temporary opening of the connection points, contaminating the treatment environment and increasing cleaning burden. Furthermore, repeated disassembly and reassembly exposes the enema tubing and bottle interface to the external environment, significantly increasing the risk of cross-contamination and potentially causing secondary infections in patients. Utility Model Content
[0003] The purpose of this application is to provide an enema solution bottle that solves the technical problems of limited capacity and cumbersome refilling operation in the prior art.
[0004] The technical solution adopted in this application is:
[0005] A bottle for administering enema solution is provided, comprising:
[0006] The bottle body has a compressible liquid storage chamber. The first end of the bottle body is provided with a first connection port, and the second connection port is provided with a second connection port. The second connection port is used to connect with a sealing cap or to be detachably connected with the first connection port on an adjacent bottle body.
[0007] A tail sleeve is provided at the tail end of the bottle body and extends outward along the axial direction of the bottle body. At least part of the bottle body is provided in the tail sleeve. When the second connection port is connected to the first connection port on the adjacent bottle body, at least part of the adjacent bottle body is provided in the tail sleeve.
[0008] As a further improvement to the above technical solution:
[0009] Optionally, the tail sleeve is provided with a plurality of through holes, and the through holes are arranged at intervals from each other along the circumference of the tail sleeve.
[0010] Optionally, the diameter of the tail sleeve is greater than or equal to the diameter of the bottle body, so that adjacent bottle bodies can be inserted into the tail sleeve.
[0011] Optionally, the tail sleeve has a support end face perpendicular to the axis of the bottle body.
[0012] Optionally, the tail sleeve and the bottle body are an integral structure.
[0013] Optionally, the inner wall of the second connection port has an internal thread to engage with the external thread on the outer wall of the first connection port on the adjacent bottle; the outer wall of the second connection port also has an external thread to engage with the internal thread on the sealing cap.
[0014] Optionally, the first connection port and / or the second connection port protrude outwards from the bottle body.
[0015] Optionally, the number of bottle bodies is at least two, and the second connection port of each bottle body is detachably connected to the first connection port of the adjacent bottle body.
[0016] Optionally, it also includes an injection head, which is connected to a first connection port on the foremost part of the bottle.
[0017] Optionally, a sealing cap is also included, which is connected to a second connection port on the last end of the bottle.
[0018] Compared with the prior art, the beneficial effects of the enema bottle provided in this application are as follows:
[0019] The enema solution bottle provided in this application specifically includes a bottle body and a tail sleeve. The interior of the bottle body forms a compressible liquid storage chamber, preferably made of medical-grade plastics such as polyethylene (PE), polypropylene (PP), or thermoplastic elastomer (TPE) that are flexible, safe, and non-toxic, to ensure safety and deformability. A first connection port is provided at the front end of the bottle body, and a second connection port is provided at the rear end. When the enema solution bottle is used independently as a single bottle body, the second connection port can be sealed with a sealing cap to prevent leakage or external contamination of the enema solution. When it is necessary to increase the enema solution capacity, multiple bottles can be connected in series. In this case, the second connection port can be detachably connected to the first connection port of the adjacent bottle body to form a continuous enema passage.
[0020] The tail sleeve is located at the tail end of the bottle body and extends outward along the axial direction of the bottle body. At least part of the bottle body is housed within the tail sleeve. When the second connecting port connects to the first connecting port on an adjacent bottle body, the adjacent bottle body is also at least partially housed within the tail sleeve; that is, adjacent bottle bodies can be nested within the tail sleeve. This provides additional support to the connection points of adjacent bottle bodies, effectively reducing the risk of loosening due to bottle compression or external forces, thereby improving the overall structural stability and resistance to deformation. The actual extension length of the tail sleeve can be adjusted according to actual needs to ensure good support even when multiple bottle bodies are connected in series, avoiding uneven stress at the connection points that could affect the continuity and safety of the enema operation.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0040] like Figures 1 to 3 As shown, this application provides an enema fluid bottle, specifically including a bottle body 1 and a tail sleeve 2. The interior of the bottle body 1 forms a compressible storage chamber, preferably made of medical-grade plastics such as polyethylene (PE), polypropylene (PP), or thermoplastic elastomer (TPE) that are flexible, safe, and non-toxic, to ensure safety and deformability. A first connection port 11 is provided at the front end of the bottle body 1, and a second connection port 12 is provided at the rear end. When a single bottle body 1 is used independently, the second connection port 12 can be sealed with a sealing cap 4 to prevent enema fluid leakage or external contamination. When it is necessary to increase the enema fluid capacity, multiple bottle bodies 1 can be connected in series. In this case, the second connection port 12 is detachably connected to the first connection port 11 of the adjacent bottle body 1, forming a continuous enema passage.
[0041] The tail sleeve 2 is located at the tail end of the bottle body 1 and extends outward along the axial direction of the bottle body 1. The bottle body 1 is at least partially housed within the tail sleeve 2. When the second connecting port 12 connects to the first connecting port 11 on an adjacent bottle body 1, the adjacent bottle body 1 is at least partially housed within the tail sleeve 2, meaning that adjacent bottle bodies 1 can be nested within the tail sleeve 2. This provides additional support to the connection points of adjacent bottle bodies 1, effectively reducing the risk of loosening due to compression of the bottle body 1 or external forces, thereby improving the overall structural stability and resistance to deformation. The actual extension length of the tail sleeve 2 can be adjusted according to actual needs to ensure good support when multiple bottle bodies 1 are connected in series, avoiding uneven stress at the connection points that could affect the continuity and safety of the enema operation.
[0042] like Figures 1 to 3 As shown, in a specific embodiment of this application, the side wall of the tail sleeve 2 is provided with multiple through holes 21, which are arranged at intervals along the circumference of the tail sleeve 2. On the one hand, the observation window formed by the through holes 21 allows for direct inspection of the sealing status at the connection between adjacent bottle bodies 1, ensuring a tight and reliable interface connection; on the other hand, the through holes 21 effectively reduce the overall weight of the tail sleeve 2 and reduce material consumption, achieving a lightweight design without affecting structural strength. The specific number of through holes 21 can be adjusted according to the size and strength requirements of the tail sleeve 2, and is usually set to 4-8, which ensures both sufficient observation field and maintains the structural integrity of the tail sleeve 2.
[0043] In one specific embodiment of this application, the inner diameter of the tail sleeve 2 is greater than or equal to the outer diameter of the bottle body 1, typically controlled within a range of 0.5-2 mm larger than the outer diameter of the bottle body 1, so that adjacent bottle bodies 1 can be inserted into the tail sleeve 2, thereby forming effective nested support. However, it should be noted that when the inner diameter of the tail sleeve 2 is too large, it will cause excessive gaps between adjacent bottle bodies 1 within the tail sleeve 2, failing to provide sufficient lateral support; while when the inner diameter of the tail sleeve 2 is too small, it will cause difficulty in inserting adjacent bottle bodies 1 or excessive frictional resistance after insertion, affecting the convenience of operation. Through repeated experiments and verification, this application has determined that the optimal difference range between the inner diameter of the tail sleeve 2 and the outer diameter of the bottle body 1 is 1-1.5 mm. This range ensures both support effectiveness and smooth assembly.
[0044] like Figures 1 to 3 As shown in a specific embodiment of this application, the end of the tail sleeve 2 is provided with a support end face 22, the plane of which is perpendicular to the axis of the bottle body 1. When the enema bottle is placed on a horizontal platform, the support end face 22 can provide a stable contact surface, ensuring that the bottle body 1 remains upright, thereby effectively preventing the bottle body 1 from rolling or shifting on the operating table. Especially when temporary placement is required during the enema operation, it can ensure that the device maintains a stable posture.
[0045] In one specific embodiment of this application, the tail sleeve 2 and the bottle body 1 are manufactured using an integrated injection molding process, eliminating the seams and connection points present in traditional split structures, thereby achieving better sealing performance. This integrated molding process uses medical-grade polypropylene or polyethylene materials, and the molded product forms a smooth curved surface connection in the transition area between the tail sleeve 2 and the bottle body 1 to avoid stress concentration.
[0046] like Figures 1 to 3 As shown, in one specific embodiment of this application, the inner wall of the second connection port 12 has an internal thread to engage with the external thread on the outer wall of the first connection port 11 on the adjacent bottle body 1, thereby achieving a reliable connection between multiple bottle bodies 1. Simultaneously, the outer wall of the second connection port 12 also has an external thread to engage with the internal thread on the sealing cap 4, thereby achieving a sealing protection of the second connection port 12 by the sealing cap 4.
[0047] like Figures 1 to 3 As shown, in a specific embodiment of this application, the first connection port 11 and the second connection port 12 adopt an outward convex structure, with the connecting part extending outward toward the outside of the bottle body 1 to effectively increase the actual usable volume of the liquid storage cavity.
[0048] like Figure 4 and Figure 5As shown, in one specific embodiment of this application, the bottle body 1 includes at least two interconnectable bottle bodies 1. Each bottle body 1 is detachably connected to the first connection port 11 of the adjacent bottle body 1 through its second connection port 12. The connection method includes, but is not limited to, threaded connection, compression fitting connection or quick-release connection structure, so as to allow flexible adjustment of the total amount of enema fluid according to actual treatment needs, while maintaining the sealing reliability of each connection part.
[0049] like Figure 4 and Figure 5 As shown, in one specific embodiment of this application, the enema solution bottle further includes an injection head 3, which is connected to the first connection port 11 of the frontmost part of the bottle body 1 via a threaded connection. The injection head 3 is made of medical-grade polycarbonate material. Multiple injection holes are evenly distributed at the front end of the injection head 3 to ensure smooth flow of the enema solution.
[0050] When an external force is applied to squeeze the bottle body 1, the volume of the compressible reservoir decreases, and the internal pressure increases, forcing the enema fluid to flow out evenly through the injection holes. The injection holes are arranged radially to create a suitable diffusion effect. An annular sealing groove with a built-in medical-grade silicone sealing ring is provided at the connection between the injection head 3 and the bottle body 1 to ensure no leakage occurs under certain working pressures.
[0051] like Figure 4 and Figure 5 As shown, in one specific embodiment of this application, the enema bottle is further provided with a sealing cap 4, which is connected to the second connection port 12 at the far end of the bottle body 1 by a threaded connection. The inner side of the sealing cap 4 is provided with an internal thread structure that matches the external thread of the second connection port 12.
[0052] It should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
