Description

Technical Field

[0001] This utility model relates to the field of enema device technology, specifically to an anti-backflow precision enema device. Background Technology

[0002] Enemas are a treatment method that involves inserting a catheter through the rectum into the colon to infuse liquid, thereby relieving constipation and gas. They can stimulate intestinal peristalsis, soften and remove feces, and also have the effects of cooling, inducing labor, diluting intestinal toxins, reducing absorption, and the low-temperature solution can help lower the temperature of patients with high fever. In addition, they can also be used to provide medication, nutrition, and water for other therapeutic purposes.

[0003] In the prior art, for example, Chinese Patent Publication No. CN220125223U discloses a novel injection-type enema device, including a connecting tube and a syringe. One end of the connecting tube is provided with an injection port, and the side of the connecting tube near the injection port is provided with an air injection port. The outer surface of the other end of the connecting tube has multiple outlet ports. An air bladder ring is installed in the middle of the connecting tube near the outlet ports. A locking component to prevent the connecting tube from moving is installed on the surface of the connecting tube. By designing injection and air channels inside the connecting tube, it is easy to separate the injection port and the air injection port. The cooperation between the air injection port and the air bladder ring makes it easy to prevent backflow of enema fluid during enema by expanding the air bladder ring. At the same time, it can also fix the enema tube and control the retention time of the enema device. The design of the locking component makes it easy to lock the connecting tube by misaligning the locking ring and the tube hole on the locking buckle. This can prevent the connecting tube from slipping out easily due to intestinal peristalsis and further ensure the retention time of the enema device.

[0004] While existing enema devices can effectively cleanse patients, the process of administering and handling the medication involves several aspects. In particular, some enema devices rely on squeezing to deliver the medication. If the squeezing method is incorrect, there is a risk of backflow of the enema solution into the drainage tube, affecting the effectiveness of the enema. Therefore, we propose an anti-backflow precision enema device. Utility Model Content

[0005] The purpose of this invention is to provide a backflow prevention precision enema device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a backflow prevention precision enema device, including an outlet shell, an outlet inner shell fixedly connected to the inner cavity of the outlet shell, a fixing component fixedly connected to the inner cavity of the outlet inner shell, a limit rod movably connected to the inner cavity of the fixing component, a one-way valve piston fixedly connected to the end of the limit rod away from the fixing component, a spring movably connected to the surface of the limit rod, the end of the spring near the fixing component being fixedly connected to the fixing component, and the end of the spring away from the fixing component being fixedly connected to the one-way valve piston.

[0007] As a further improvement to this technical solution, a control valve is fixedly connected to the side of the outlet inner shell away from the spring. The space reserved between the control valve and the one-way valve piston is the inlet groove hole. The space reserved between the one-way valve piston and the fixed assembly is the first outlet. A second outlet is provided on the side of the inner cavity of the outlet outer shell away from the outlet inner shell.

[0008] As a further improvement to this technical solution, a guide tube is fixedly connected to the side of the control valve away from the outlet housing, and an enema body is fixedly connected to the end of the guide tube away from the control valve. A pressing rod is movably connected to the side of the enema body away from the guide tube, and a pressing shell is fixedly connected to the side of the enema body near the pressing rod.

[0009] As a further improvement to this technical solution, a liquid storage bottle is movably connected to the surface of the enema device body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This anti-backflow precision enema device features a combination design of a one-way valve piston and spring that effectively prevents backflow of the enema solution, thereby improving the effectiveness of the enema operation. The control valve allows for better control of the flow rate and volume of the enema solution, making the enema process more precise. The linkage between the pressing shell and the pressing rod simplifies the process of extracting the enema solution, making the entire system easier to operate. The one-way valve design reduces the risk of the solution accidentally entering the guide tube, increasing operational safety. The one-way flow mechanism also reduces the possibility of contamination of the solution during operation. Attached Figure Description

[0020] Please see Figure 2 and Figure 3 As shown, this utility model provides a backflow-prevention precision enema device, including an outlet shell 7, an outlet inner shell 14 fixedly connected to the inner cavity of the outlet shell 7, a fixing component 10 fixedly connected to the inner cavity of the outlet inner shell 14, a limiting rod 11 movably connected to the inner cavity of the fixing component 10, a one-way valve piston 8 fixedly connected to the end of the limiting rod 11 away from the fixing component 10, and a spring 9 movably connected to the surface of the limiting rod 11. The end of the spring 9 near the fixing component 10 is fixedly connected to the fixing component 10, and the end of the spring 9 away from the fixing component 10 is fixedly connected to the one-way valve piston 8. The one-way valve piston 8 is opened by water pressure, allowing the medicine to pass through; when there is no water pressure, the inlet slot 12 is closed under the action of the spring 9 to prevent backflow. The spring 9 provides the closing force for the one-way valve piston 8. When there is no water pressure, the one-way valve piston 8 is reset. Through the design of the one-way valve piston 8 and the spring 9, the problem of backflow of enema liquid caused by improper medicine squeezing method is solved, and the reliability and safety of enema operation are improved.

[0021] Please see Figure 3As shown, in this embodiment, a control valve 6 is fixedly connected to the side of the outlet inner shell 14 away from the spring 9. The space reserved between the control valve 6 and the one-way valve piston 8 is the inlet slot 12. The space reserved between the one-way valve piston 8 and the fixing assembly 10 is the first outlet 13. A second outlet 15 is provided on the side of the inner cavity of the outlet outer shell 7 away from the outlet inner shell 14. The structure of the control valve 6, the inlet slot 12, and the first outlet 13 can better control the flow path of the liquid medicine, making the flow of the liquid medicine more orderly and reducing waste.

[0022] Please see Figure 1 As shown, further, a guide pipe 5 is fixedly connected to the side of the control valve 6 away from the outlet housing 7. The end of the guide pipe 5 away from the control valve 6 is fixedly connected to the enema body 3. The side of the enema body 3 away from the guide pipe 5 is movably connected to the pressing rod 2. The side of the enema body 3 near the pressing rod 2 is fixedly connected to the pressing shell 1. Connecting the guide pipe 5, the enema body 3, the pressing rod 2, and the pressing shell 1 makes the whole system a complete operating unit, simplifying the operation steps and improving the convenience of use.

[0023] Please see Figure 1 As shown, specifically, a liquid storage bottle 4 is movably connected to the surface of the enema body 3. The liquid storage bottle 4 is movably connected to the enema body 3, which facilitates the replacement and replenishment of the medicine, enhances the flexibility of the equipment, and also facilitates the management and use of the medicine.

[0024] Please see Figures 1-3 As shown, the anti-backflow precision enema device is designed to achieve unidirectional flow of the medication through a one-way valve piston 8 and spring 9 mechanism, preventing backflow and ensuring smooth and effective enema operation. The device is easy to operate, compact in structure, and suitable for use in medical environments.

[0025] In summary, the working principle of this solution is as follows:

[0026] First, the medicine is poured into the storage bottle 4. By pressing the housing 1 and pushing the pressing rod 2, the enema body 3 will draw the medicine out of the storage bottle 4 and flow into the guide tube 5. Then, the control valve 6 is opened, and the medicine enters the inlet hole 12 through the control valve 6. The medicine pushes open the one-way valve piston 8 by the water pressure. Since the fixing component 10 is fixedly connected to the inner cavity of the outlet inner shell 14, the limit rod 11 on the one-way valve piston 8 will move back and forth through the fixing component 10, thereby ensuring that the one-way valve piston 8 will not be misaligned. The medicine will be discharged from the first outlet 13 to the second outlet 15. When the medicine is not being injected, the one-way valve piston 8 does not feel the water pressure. Under the action of the spring 9, the one-way valve piston 8 will automatically block the inlet hole 12 to block the backflow of liquid. When it is necessary to continue injecting medicine, the water pressure will first flush out the backflow of liquid.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
