Description

Technical Field

[0001] This utility model relates to the field of straw technology, and in particular to straws that prevent accidental aspiration. Background Technology

[0002] Paralyzed patients often experience a significant decline or even complete loss of muscle control in their limbs due to damage to the nervous system or degeneration of motor function, severely limiting their daily activities. These patients frequently face complications such as muscle atrophy and joint stiffness, and prolonged bed rest increases the risk of secondary health problems such as pressure sores and lung infections, placing extremely high demands on the quality of nursing care and rehabilitation techniques.

[0003] If a paralyzed patient also loses the ability to swallow, the feeding process requires the use of assistive tools, with straws being a common solution for delivering liquid foods. This method uses negative pressure to deliver pureed or liquid foods to the mouth, but the straw diameter and food viscosity must be strictly controlled to avoid the risk of choking. To improve safety, some smart straws have integrated flow regulation functions, working with cameras and pressure sensors to monitor swallowing status in real time, helping caregivers dynamically adjust the feeding speed, ensuring nutritional intake while reducing the probability of aspiration complications.

[0004] In existing technologies, patients consume liquids through straws, but this process presents several problems. For instance, the straws used in current technologies are all flexible and need to be held in the mouth to suck, but they are prone to falling off if held in the mouth for a long time. This requires caregivers to hold the straw with the patient. Secondly, if the suction is strong and the flow rate is fast during the sucking process, it can cause the patient to choke. Utility Model Content

[0005] The purpose of this invention is to provide a straw that prevents accidental aspiration, thereby addressing the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-aspiration suction tube, comprising a flexible tube and a connecting tube, wherein the inner diameter of the connecting tube is larger than the inner diameter of the flexible tube, the connecting tube includes a horizontal end and two vertical ends, and a fixing component is provided at the bottom of each of the two vertical ends of the connecting tube, and a one-way component is also provided inside the flexible tube.

[0007] As a further description of the above technical solution: the fixing component includes two limiting rings, and the top ends of the two limiting rings are provided with threaded grooves, which are threadedly connected to both ends of the hanging pipe.

[0008] As a further description of the above technical solution: the limiting ring is provided with an insertion hole, the cross-section of the insertion hole is funnel-shaped, the upper end of the insertion hole is narrow and the lower end is wide.

[0009] As a further description of the above technical solution: a section of the hose is provided with a spiral guide track.

[0010] As a further description of the above technical solution: the one-way component includes a one-way tube, which is disposed on a flexible tube. The inner diameter of the one-way tube is larger than the inner diameter of the flexible tube. A filter element is fixedly installed inside the one-way tube. A spring is fixedly installed at one end of the filter element, and a blocking ball is fixedly installed at one end of the spring. The blocking ball blocks the connection between the flexible tube and the one-way tube.

[0023] 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.

[0024] Reference Figure 1-6 The anti-aspiration straw includes a flexible tube 1 and a hanging tube 3. The inner diameter of the hanging tube 3 is larger than that of the flexible tube 1. The hanging tube 3 includes one horizontal end and two vertical ends. The bottom of each of the two vertical ends of the hanging tube 3 is provided with a fixing component. The flexible tube 1 also has a one-way component inside. The position of the hanging tube 3 can be adjusted according to the depth of the patient's oral cavity so that the length of the flexible tube 1 passing through one end of the hanging tube 3 can adapt to the patient's oral cavity, making it convenient for the patient to use the flexible tube 1 to suck up liquid food or water. The patient can put one end of the hanging tube 3 into their mouth, and the hanging tube 3 can be hung on one side of the corner of the mouth, eliminating the need for the caregiver to hold the flexible tube 1 throughout the process, reducing the risk of the flexible tube 1 falling during use. Secondly, the one-way component can prevent liquid from leaking from one end of the flexible tube 1 when not sucking. The hanging tube 3 is made of food-grade stainless steel, increasing safety.

[0025] As a preferred technical solution of this embodiment, the fixing component includes two limiting rings 6, and the top ends of the two limiting rings 6 are provided with threaded grooves 7, which are threadedly connected to both ends of the hanging pipe 3; after the position of the hanging pipe 3 on the hose 1 is adjusted, the fixing between the hose 1 and the hanging pipe 3 can be achieved by installing the limiting rings 6 on both sides.

[0026] As a preferred technical solution in this embodiment, the limiting ring 6 is provided with an insertion hole 8. The cross-section of the insertion hole 8 is funnel-shaped, with the upper end of the insertion hole 8 being narrow and the lower end being wide. The upper end of the insertion hole 8 can be squeezed with the hose 1 to achieve an interference fit, thereby fixing the hose 1.

[0027] As a preferred technical solution in this embodiment, a section of the hose 1 is provided with a spiral guide track 10; the spiral guide track 10 can disperse the liquid through centrifugal force, thereby reducing the flow rate of the liquid and playing a role in preventing choking.

[0028] As a preferred embodiment, the one-way component includes a one-way tube 9, which is disposed on the hose 1. The inner diameter of the one-way tube 9 is larger than the inner diameter of the hose 1. A filter element 11 is fixedly installed inside the one-way tube 9. A spring 12 is fixedly installed at one end of the filter element 11, and a sealing ball 13 is fixedly installed at one end of the spring 12. The sealing ball 13 blocks the connection between the hose 1 and the one-way tube 9. The filter element 11 can filter the liquid on the one hand, and the spring 12 can elastically connect the sealing ball 13. When the patient uses the hose 1, a negative pressure is generated inside, which can push the liquid and separate the sealing ball 13 from the connection between the hose 1 and the one-way tube 9, thereby realizing the flow of liquid. When the patient does not use the hose 1, the sealing ball 13 will block the connection between the hose 1 and the one-way tube 9 due to the action of the spring 12, thereby realizing the leak-proof function of the hose 1.

[0029] As a preferred technical solution in this embodiment, the top end of the connecting pipe 3 is provided with multiple through holes 4; the through holes 4 are provided to prevent negative pressure from being generated inside the connecting pipe 3, which would prevent the hose 1 from sliding inside the connecting pipe 3.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
