Description

Technical Field

[0001] This utility model belongs to the field of feeding tube technology, specifically a double-lumen feeding tube for enterostomy. Background Technology

[0002] To reduce the risk of anastomotic leakage after emergency bowel resection or sphincter-preserving surgery for low rectal cancer, a prophylactic ileostomy is usually performed concurrently. Before the stoma is closed, the distal intestine often needs to be pre-adapted, for example, by filtering intestinal fluid and injecting it into the distal intestine, or by infusing nutritional fluid through a stoma tube.

[0003] However, there are currently no enteral nutrition tubes specifically designed for enterostomies on the market. In clinical practice, urinary catheters are often used instead of enteral nutrition tubes. However, urinary catheters are not compatible with the enteral nutrition bags used in clinical practice, and they are prone to dislodgement due to the lack of a fixing device.

[0004] Therefore, a double-lumen feeding tube specifically designed for enterostomy is proposed to address the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a double-lumen feeding tube specifically for enterostomies, thereby solving the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a double-lumen feeding tube for enterostomy, comprising a feeding tube body and a fixing component sleeved on the outside of the feeding tube body, wherein an air bladder membrane is fixedly connected to the lower part of the outer surface of the feeding tube body, and both the fixing component and the air bladder membrane are used for fixing the feeding tube body.

[0009] The nutrient tube body includes a nutrient tube body, a first connector for connecting nutrient solution is fixedly connected to the top of the nutrient tube body, an inflation tube is fixedly connected to the upper part of the outer side wall of the nutrient tube body, an air passage is opened inside the tube wall of the nutrient tube body, and an opening communicating with the outside of the nutrient tube body is opened at the upper and lower parts of the air passage. The upper opening communicates with the inside of the inflation tube, and the lower opening is located inside the air bladder membrane.

[0010] Preferably, the inflation tube is provided with a regulating valve for opening and closing the internal passage of the inflation tube, and the regulating valve is fixed at a designated position on the inflation tube. The end of the inflation tube away from the nutrient tube body is fixedly connected to a second connector for connecting a syringe.

[0011] Preferably, a plurality of conical rings are fixedly connected to the middle of the outer surface of the nutrient tube body, and the plurality of conical rings are all located on the upper part of the air bladder membrane.

[0013] Preferably, an airbag ring is fixedly connected to the bottom of the arc-shaped ring plate, and the arc-shaped ring plate can engage with the bottom of any one of the plurality of conical rings.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a double-lumen feeding tube specifically for enterostomy, which has the following beneficial effects:

[0016] 1. This utility model, by setting a feeding tube body and setting a first connector for connecting nutrient solution in the feeding tube, and setting an air bladder membrane at the end of the feeding tube body, allows the device to be inserted into the stoma during use. Inflation of the air bladder membrane through the inflation tube in the feeding tube body causes it to expand, thereby fixing the feeding tube body and preventing the feeding tube from falling out during use. The first connector can be perfectly matched with the nutrient bag to prevent leakage when providing nutrient solution. The setting of this device fills the problem of the lack of dedicated feeding tubes for enterostomies on the market.

[0017] 2. This utility model includes a fixing component in the device and multiple conical rings on the lower part of the outer wall of the feeding tube body. The fixing component is set on the uppermost conical ring at the factory. After the feeding tube body is fixed inside the stoma by the air bag membrane, the fixing component can be slid down to fit the fixing component with the patient's skin and be limited by the corresponding conical rings. This can achieve bilateral fixation of the feeding tube, which not only improves the stability of the device but also facilitates the installation and operation of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a double-lumen feeding tube for enterostomy, including a feeding tube body 1 and a fixing component 2 sleeved on the outside of the feeding tube body 1. An air bladder membrane 3 is fixedly connected to the lower part of the outer surface of the feeding tube body 1. Both the fixing component 2 and the air bladder membrane 3 are used to fix the feeding tube body 1.

[0028] Furthermore, such as Figures 1-4 As shown, the main body 1 of the feeding tube includes a feeding tube body 11. A first connector 12 for connecting to nutrient solution is fixedly connected to the top of the feeding tube body 11. An inflation tube 14 is fixedly connected to the upper part of the outer wall of the feeding tube body 11. An air passage 17 is opened inside the tube wall of the feeding tube body 11. The upper and lower parts of the air passage 17 are opened to communicate with the outside of the feeding tube body 11. The upper opening communicates with the inside of the inflation tube 14, and the lower opening is located inside the air bladder membrane 3. An adjustment valve 15 for opening and closing the internal passage of the inflation tube 14 is provided on the inflation tube 14. The adjustment valve 15 is fixed at a designated position on the inflation tube 14. A second connector 16 for connecting to a syringe is fixedly connected to the end of the inflation tube 14 away from the feeding tube body 11.

[0029] The above solution involves setting up a nutrient tube body 1 with a first connector 12 for connecting nutrient solution. An air bladder membrane 3 is also provided at the end of the nutrient tube body 11. When in use, the device can be inserted into the stoma, and air is pumped into the air bladder membrane 3 via the inflation tube 14 in the nutrient tube body 1, causing it to expand and thus securing the nutrient tube body 1 and preventing it from coming loose during use. The first connector 12 perfectly fits the nutrient bag, preventing leakage when providing nutrient solution.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a plurality of conical rings 13, which are equally spaced vertically distributed, are fixedly connected to the middle of the outer surface of the nutrient tube body 11, and the plurality of conical rings 13 are all located on the upper part of the airbag membrane 3. The fixing component 2 includes an arc-shaped ring plate 21, which is slidably connected to the nutrient tube body 11. An airbag ring 22 is fixedly connected to the bottom of the arc-shaped ring plate 21, and the arc-shaped ring plate 21 can engage with the bottom of any one of the plurality of conical rings 13.

[0031] With the above solution, the fixing component 2, combined with the inflated air bladder membrane 3, and the corresponding conical ring 13, can be used to limit the movement of the feeding tube body 11, making the fixing of the feeding tube very convenient.

[0032] Working principle: First, insert the end of the feeding tube body 1 into the patient's stoma. Then, connect the syringe to the second connector 16 and open the regulating valve 15. Inflate the balloon membrane 3 with the syringe to make the balloon membrane 3 expand. Then, close the regulating valve 15, remove the syringe, and gently pull the feeding tube to make the expanded balloon membrane 3 fit against the patient's abdominal wall. Then, slide the fixing component 2 towards the patient's side to make the balloon ring 22 in the fixing component 2 fit against the patient's skin and limit the fixing component 2 and the conical ring 13 in the feeding tube body 1, thus fixing the feeding tube inside and outside. Then, connect the first connector 12 to the nutrient solution. When the nutrient solution is not needed, use a heparin cap to seal the first connector 12. When the feeding tube needs to be removed, turn the regulating valve 15 to expel the gas from the balloon membrane 3, and then the feeding tube can be removed.

[0033] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
