Description

Technical Field

[0001] This utility model relates to the field of feeding tubes, specifically to an intermittent oral feeding tube with temperature sensing and pH monitoring functions. Background Technology

[0002] Intermittent oral feeding is used in the recovery phase of swallowing function in stroke patients with dysphagia to stimulate the cricopharyngeal muscle, promote swallowing function recovery, and ensure the patient's nutrition. This technique is widely used in long-term rehabilitation patients due to its flexibility and minimal damage to swallowing function; most family members can independently perform tube feeding at home after training. However, there are two main problems. First, family members may find it difficult to ensure accurate positioning, potentially leading to the tube being misplaced into the trachea or insufficiently inserted, causing complications such as choking. Visualization equipment can address these issues, but it is cumbersome and expensive. Second, to ensure patient comfort, the nutrient solution needs to be kept within a suitable temperature range. Pre-measuring the temperature with a thermometer is not intuitive and is inconvenient. Utility Model Content

[0015] Figure 1 This is a schematic diagram of an intermittent oral feeding tube with temperature and pH monitoring functions. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1 This is a schematic diagram of the intermittent oral feeding tube with temperature sensing and pH monitoring functions provided by this utility model. The diagram shows the tube in its split state.

[0018] The intermittent feeding tube with temperature and pH monitoring functions includes a flexible tube 1, a first connector 11, a cap 12, a positioning seat 13, a temperature sensing tube 14, a second connector 15, a filter connector 16, an end cap 17, a guide wire 2, a handle 21, and a monitoring tube 22.

[0019] A first connector 11 is fixedly installed at the head end of the hose 1. A ring-shaped positioning seat 13 is provided on the outer wall of the first connector 11 for installing the fixing device.

[0020] A connecting ring is fitted onto the upper part of the outer wall of the first connector 11. The connecting ring is connected to the cap 12 via a connecting strip to prevent the cap 12 from falling off. When the hose 1 is not in use, the cap is inserted into the head end of the first connector 11 to seal it. When in use, it is pulled out.

[0021] In use, a temperature-sensing tube 14 is inserted into the first end of the first connector 11. The temperature-sensing tube 14 is a 10-cm-long flexible tube made of thermochromic material. A second connector 15 is fixedly installed at the first end of the temperature-sensing tube 14. The second connector 15 is used to insert a syringe or a filter connector 16. The filter connector 16 is also used to insert a syringe to inject nutrient solution. Whether or not the filter connector 16 is needed to filter the nutrient solution depends on the actual situation during use.

[0022] When injecting nutrient solution into the tubing 1 through the second connector 15 or the filter connector 16, the temperature sensing tube 14 can display the temperature of the nutrient solution in a timely and intuitive manner, serving as a last resort to ensure that the temperature of the nutrient solution is within a reasonable range suitable for the patient.

[0023] The end of the tubing 1 is integrally connected to an end cap 17, which seals the end of the tubing 1. Multiple injection holes 18 are provided on the side wall of the end of the tubing 1 near the end cap 17. When injecting nutrient solution, the nutrient solution is released from the injection holes 18 to reduce impact and discomfort.

[0024] The total length of hose 1 is 50 cm. Starting from 35 cm from the end of hose 1, there are graduations every 5 cm, up to the first connector 11.

[0025] The guidewire 2 has a handle 21 at its tip for easy gripping. A 3cm long tubular structure made of metal mesh, namely the monitoring tube 22, is fixedly installed at the tail end of the guidewire 2. The tube is filled with pH-sensitive hydrogel as the monitoring medium.

[0026] If the end of the flexible tube 1 reaches the stomach, the gastric fluid passes through the monitoring tube 22, causing a change in the volume of the monitoring medium, thus allowing the insertion position to be determined after the guide wire 2 is pulled out.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
