[0002] Nasogastric feeding, also known as nasogastric gavage, involves manually inserting a feeding tube into the esophagus through the nasal cavity under special circumstances. The food is first ground into a paste using a grinder, and a large syringe is connected to the large feeding port at the bottom of the feeding tube connector. After a secure connection, a manually pressurized plunger is used to inject water and food into the patient's stomach. This helps provide water and food to patients who cannot swallow independently, maintaining their metabolism, weight, and nutrition. In current medical systems, nasogastric feeding primarily involves inserting a feeding tube into the patient's stomach through the nasal cavity, with the inner end of the tube inserted along the nasal cavity and the outer end connected to a funnel or infusion set.
[0003] In existing technology, the nasogastric tube has a certain length reserved at the outer end for feeding, which resembles an elephant trunk and affects the patient's appearance and daily activities. For patients with unstable emotions, it is easy for them to grab the outer end of the nasogastric tube and pull it out. Repeated insertion and removal of the nasogastric tube can cause additional pain and harm to the patient.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0033] In existing technology, the nasogastric tube has a certain length reserved at the outer end for feeding, which resembles an elephant trunk and affects the patient's appearance and daily activities. For patients with unstable emotions, it is easy for them to grab the outer end of the nasogastric tube and pull it out. Repeated insertion and removal of the nasogastric tube can cause additional pain and harm to the patient.
[0034] Based on the aforementioned problems in the existing technology, such as Figure 1 As shown, this utility model provides a combined nasogastric tube, which includes: a first tube body 100, one end of which is provided with a plurality of guide holes 120, and the other end of which is provided with a first connector 110; a second tube body 200, one end of which is provided with a second connector 210, which is detachably connected to the first connector 110. When the first connector 110 and the second connector 210 are combined, the first tube body 100 and the second tube body 200 are in communication; the other end of the second tube body 200 is provided with an infusion end 220, which is funnel-shaped.
[0035] This invention features a nasogastric tube consisting of a detachably connected first tube 100 and a second tube 200. In use, the first tube 100 is inserted into the patient's nasal cavity, while the second tube 200 is connected to the first tube 100 outside the nasal cavity. Liquid food can be infused through the infusion tip 220 and the drainage hole 120. When not in use, the second tube 200 can be separated from the first tube 100. After separation, only a small portion of the first tube 100 is exposed, which reduces the impact on the patient's appearance, avoids affecting the patient's daily activities, and prevents patients with unstable emotions from pulling out the tube.
[0036] In the above embodiments, such as Figure 1As shown, the main body of the combined nasogastric tube of this utility model consists of a first tube 100 and a second tube 200. The first tube 100 and the second tube 200 are separately arranged. The first tube 100 is used to be placed inside the patient's body, and the second tube 200 is used to be connected to the outside of the patient's body. One end of the first tube 100 is provided with a plurality of guide holes 120, which are used to guide the liquid food inside the first tube 100 into the patient's stomach. The other end of the first tube 100 is provided with a first connector 110, which is used to connect with a second connector 210 provided at one end of the second tube 200, thereby forming a complete nasogastric tube structure.
[0037] In this embodiment, in actual use, such as Figure 3 As shown, one end of the first tube 100 with a drainage hole 120 extends into the patient's stomach along the nasal cavity, pharynx, and esophagus, and is fixed in place. It is replaced approximately every 15 days to one month. One end of the first tube 100 with a first connector 110 is located outside the patient's nostril and remains in place during the aforementioned replacement period. When the second tube 200 and the first tube 100 are disassembled, only the first connector 110 is exposed outside the patient's face, which can relatively improve the aesthetics of the patient's face and reduce the patient's negative emotions.
[0038] like Figure 1 As shown, a second connector 210 adapted to the first connector 110 is provided at one end of the second tube 200. The second connector 210 is detachably connected, and when the second connector 210 is combined with the first connector 110, the first tube 100 and the second tube 200 are connected and the connection is sealed. An infusion end 220 is provided at the other end of the second tube 200. The infusion end 220 is integrally formed with the second tube 200 and is funnel-shaped. It can be used to assist in the infusion of nutrient solution, water, liquid food, etc. The appearance after the first tube 100 and the second tube 200 are connected is as follows. Figure 2 As shown, in actual use, medical staff use a syringe to inject nutrient solution, water, liquid food, etc. into the second tube 200 through the infusion end 220, and under the guidance of the second tube 200, it enters the first tube 100. Under the action of gravity and air pressure, it flows out from several guide holes 120 and enters the patient's stomach, thereby achieving the nutritional supply to the patient.
[0039] In the above embodiments, the first tube 100 and the second tube 200 can be made of materials such as silicone or plastic, and should have a certain degree of elasticity to adapt to changes in shape within the patient's body cavity. Simultaneously, the surface should be smooth to facilitate intubation. Furthermore, in one possible embodiment of this invention, the first tube 100 and the second tube 200 can be made of transparent material to allow medical personnel to observe the flow of the liquid food and determine whether the infused nutrients have successfully entered the patient's body.
[0040] In another possible embodiment of this utility model, such as Figure 3 As shown, in a specific configuration, the diameter of the first connector 110 should be larger than the diameter of the first tube 100. The diameter of the first tube 100 is adapted to the diameter of the patient's nasal cavity. The first connector 110, which is larger than the diameter of the first tube 100, can be locked onto the outside of the patient's nostrils, thereby preventing the first connector 110 of the first tube 100 from falling into the patient's body. On the other hand, since the exposed part of the first tube 100 outside the patient's body is very short, it is difficult for the patient to grasp the first tube 100 by hand, which can reduce the probability of the patient performing tube removal when in a bad mood and avoid the patient suffering from repeated tube insertion.
[0041] In this embodiment, as Figure 1 As shown, the outer side of the first connector 110 is provided with a thread 111. Correspondingly, the second connector 210 is sleeved and connected to the first connector 110. The inner wall of the second connector 210 is provided with a structure that is adapted to the thread 111, so that medical staff can quickly connect the first connector 110 and the second connector 210.
[0042] In one possible implementation, the above-mentioned combined nasogastric tube further includes a cap 400. The inner wall of the cap 400 is provided with a structure adapted to the thread 111. When the second connector 210 is disassembled, the cap 400 can replace the second connector 210 and be installed on the first connector 110, thereby protecting the end of the first connector 110 and preventing germs and dust in the air from entering the first connector 110.
[0043] Furthermore, in another possible embodiment of this utility model, the first tube 100 includes multiple types, specifically, the length and / or diameter of the first tube 100 are different. That is, in this embodiment, medical personnel can preset the size of the combined nasogastric tube according to the actual situation of different patients, forming multiple models. For example, a short-sized, small-diameter first tube 100 for pediatric patients for insertion; a long-sized, large-diameter first tube 100 for adult male patients for insertion; a medium-length, medium-diameter first tube 100 for adult female patients for insertion, etc. In actual setup, those skilled in the art can preset the type of the first tube 100 based on actual statistical data, and this application does not limit this.
[0044] In this embodiment, the second tube 200 can be set as a universal tube, that is, the first connector 110 of different types of first tubes 100 are the same and can be combined with the second connector 210 on the second tube 200, thereby achieving the effect of reducing production costs while adapting to patients with different conditions.
[0045] In another possible embodiment of this utility model, such as Figure 1 As shown, in order to reduce the pain caused to patients during the insertion and removal of the combined nasogastric tube, in this embodiment, one end of the first tube body 100 with a drainage hole 120 is closed and the end is set in a hemispherical shape. The outer side of the first tube body 100 is smooth. During the actual insertion and removal of the tube, the hemispherical end can play a guiding role to avoid damage to the patient's internal cavity. In this embodiment, the above-mentioned drainage holes 120 are set on the side wall of the first tube body 100 and close to the end, so as to achieve the drainage function while avoiding the accumulation of liquid inside the first tube body 100.
[0046] Furthermore, to avoid backflow in the first pipe body 100, in this embodiment, the aforementioned plurality of guide holes 120 are preferably configured as unidirectional guide holes 120. Specifically, as shown in the figure below... Figure 4As shown, a first valve 121 and a second valve 122 can be symmetrically arranged inside the drainage hole 120. The first valve 121 and the second valve 122 are elastic valves. The first valve 121 and the second valve 122 are arranged along a predetermined arc and abut against each other. In this embodiment, the cross-section of the first valve 121 and the second valve 122 can be set as a canine tooth shape, with their tips abutting against each other. The concave side of the first valve 121 and the second valve 122 faces the outside of the first tube 100. In actual use, the pressure generated by the presence of liquid food in the first tube 100 can push the elastic first valve 121 and the second valve 122. At this time, the first valve 121 and the second valve 122 deform and separate from each other, so that the drainage hole 120 forms a through hole, thereby achieving the effect of supplying nutrients to the patient's stomach.
[0047] When a certain amount of liquid nutrients are present inside the patient's stomach, the liquid exerts pressure on the first valve 121 and the second valve 122 outside the first tube 100, i.e., on... Figure 4 The concave surfaces of the first valve 121 and the second valve 122 shown in the figure form pressure. However, as the pressure increases, the first valve 121 and the second valve 122 come into closer contact with each other, keeping the guide hole 120 closed, thus achieving the effect of preventing backflow.
[0048] In another possible embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the above-mentioned combined nasogastric tube also includes a guide 300, which consists of a handle 310 and a guide wire 320. The handle 310 and the guide wire 320 are fixedly connected. In specific settings, the guide wire 320 is made of steel wire and has a certain degree of elasticity. The length of the guide wire 320 is adapted to the length of the first tube 100 and the second tube 200 after connection. The function of the guide wire 320 is to guide the liquid in the first tube 100 and the second tube 200 to avoid the formation of air bubbles in the first tube 100 and the second tube 200 when pouring the liquid, which would prevent the liquid from flowing smoothly. In specific use, medical staff can hold the handle 310 and repeatedly pull the guide wire 320 to remove air bubbles in the first tube 100 and the second tube 200.
[0049] In this embodiment, since the length of the guide wire 320 is adapted to the length of the first tube 100 and the second tube 200 after connection, when the first tube 100 and the second tube 200 are separated, the flow guide 300 needs to be removed in advance. That is, the flow guide 300 can be pulled out from the first tube 100 and the second tube 200. For easy storage, the handle 310 and the infusion end 220 can be set to be detachably connected, so that after the flow guide 300 is pulled out and the second tube 200 is disassembled, the flow guide 300 and the second tube 200 can be stored together.
[0050] Based on the above embodiments, the actual use of this utility model's combined nasogastric tube is as follows:
[0051] like Figure 3 As shown, firstly, the first tube 100 and the second tube 200 are combined. The first tube 100 is inserted into the stomach sac along the patient's nasal cavity, pharynx, and esophagus. At this time, the first connector 110 is located outside the patient's nostrils, i.e., it is installed in place.
[0052] When there is no need to administer nutrients to the patient, the second tube 200 can be disassembled, thereby reducing the structural size of the combined nasogastric tube exposed on the patient's face. This can make the patient's appearance more aesthetically pleasing, reduce the probability of emotionally unstable patients manually removing the tube, and facilitate the patient's daily activities.
[0053] When it is necessary to administer nutrients to a patient, the second tube 200 can be combined with the first connector 110 on the first tube 100 via the second connector 210. Then, the guide wire 320 of the guide member 300 is inserted into the first tube 100 and the second tube 200. Nutrients are then administered to the patient's stomach using an infusion device such as a syringe. Due to the structural design of the first valve 121 and the second valve 122 on the guide hole 120, unidirectional nutrient administration can be achieved, preventing reflux.
[0054] Based on the above embodiments, this utility model also provides a catheter device, which includes the combined nasogastric tube described in the above embodiments. The combined nasogastric tube includes: a first tube body, one end of which is provided with a plurality of drainage holes, and the other end of which is provided with a first connector; a second tube body, one end of which is provided with a second connector, which is detachably connected to the first connector. When the first connector and the second connector are combined, the first tube body and the second tube body are in communication; the other end of the second tube body is provided with an irrigation tip, which is funnel-shaped. This utility model sets the nasogastric tube as a detachably connected first tube body and second tube body. In use, the first tube body is inserted into the patient's nasal cavity, and the second tube body is connected to the first tube body outside the nasal cavity. Liquid food can be infused through the irrigation tip and drainage holes. When not in use, the second tube body can be separated from the first tube body. After separation, only a small part of the first tube body is exposed, which can reduce the impact on the patient's appearance, avoid affecting the patient's daily activities, and prevent patients with unstable emotions from pulling out the tube.
[0055] In summary, this utility model provides a combined nasogastric tube and catheter device. The combined nasogastric tube includes: a first tube body, one end of which has several drainage holes, and the other end of which has a first connector; a second tube body, one end of which has a second connector, which is detachably connected to the first connector. When the first and second connectors are combined, the first and second tube bodies are in communication; the other end of the second tube body has an irrigation tip, which is funnel-shaped. This utility model, by configuring the nasogastric tube as a detachably connected first and second tube body, allows the first tube body to be inserted into the patient's nasal cavity during use, while the second tube body connects to the first tube body outside the nasal cavity. Liquid food can be infused through the irrigation tip and drainage holes. When not in use, the second tube body can be separated from the first tube body, with only a small portion of the separated first tube body exposed, reducing the impact on the patient's appearance, avoiding interference with daily activities, and preventing patients with unstable emotions from pulling out the tube.
[0056] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
