Description

Technical Field

[0001] This utility model relates to the technical field of gastric tube fixation devices, and in particular to a gastric tube traction device. Background Technology

[0002] In some esophageal cancer surgeries, extensive tissue resection and reconstruction may be involved, requiring time to heal. In such cases, the placement of a gastric tube (including orogastric tubes and nasogastric tubes) can reduce the burden on the digestive tract and aid recovery. Currently, gastric tubes are generally secured with medical tape. For example, medical tape is cut into appropriate shapes (such as an I-shape or a herringbone shape), one end of which is attached to the tip of the nose or both sides of the nostrils, and the other end is wrapped and secured to the gastric tube (i.e., the portion of the gastric tube below the nostril; see [link to relevant documentation]). Figure 1 For example, medical tape 8 can be used to fix the gastric tube 7 to the face prop 10 below the nose. To help better secure the gastric tube, additional medical tape can be used to fix the extension of the gastric tube to the patient's cheek. However, long-term use of tape may cause contact dermatitis, allergies, or epidermal peeling, resulting in low patient comfort. Moreover, when the patient moves, sweats, or has facial oil secretion, the tape may loosen and easily fall off, causing the gastric tube to shift or even dislodge, affecting treatment. This method of fixation is neither comfortable nor secure, and it is inconvenient to operate, increasing the workload of nursing staff.

[0003] Therefore, overcoming the low comfort and insecure fixation of gastric tubes using medical tape has become a technical problem that needs to be solved. Utility Model Content

[0046] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0047] See Figures 1 to 5 Specific Embodiment 1 provides a gastric tube traction device, including a first fixing strap 1, a fixing rope 6 for fixing the gastric tube 7, and a second fixing strap 2. The front section 1-1 of the first fixing strap is detachably connected to one end of the fixing rope 6, facilitating the fixing and removal of one end of the fixing rope 6. The front section 2-1 of the second fixing strap is detachably connected to the other end of the fixing rope 6, facilitating the fixing and removal of the other end of the fixing rope 6. This facilitates the replacement of the fixing rope 6. The fixing rope 6, after being contaminated with the patient's sweat and / or facial oil and / or nasal mucus, can be washed and disinfected and reused. The rear section 1-2 of the first fixing strap is provided with several adjustment holes 1-3, and the rear section 2-2 of the second fixing strap is provided with adjustment buttons 2-3 that match the adjustment holes 1-3. The adjustment buttons 2-3 and the adjustment holes 1-3 are detachably connected and have several adjustment holes 1-3 for adjusting the connection position between the first fixing strap 1 and the second fixing strap 2, indirectly adjusting the tightness of the first fixing strap 1 and the second fixing strap 2 in pulling the fixing rope 6.

[0048] The inner surfaces of the rear section 1-2 of the first fixation strap and / or the inner surfaces of the rear section 2-2 of the second fixation strap are provided with anti-slip parts A (not shown in the attached drawings). Anti-slip parts A are made of silicone. In this embodiment 1, the inner surfaces of the rear section 1-2 of the first fixation strap and the inner surfaces of the rear section 2-2 of the second fixation strap are provided with anti-slip parts A. Anti-slip parts A correspond to the back of the patient's head, increasing the friction between the first fixation strap 1, the second fixation strap 2 and the hair on the back of the patient's head. This helps the first fixation strap 1 and the second fixation strap 2 to be positioned above the corresponding ears, preventing the first fixation strap 1 and the second fixation strap 2 from loosening and slipping down, which would cause the fixation rope 6 to fail to fix the gastric tube 7. It also prevents the first fixation strap 1 and the second fixation strap 2 from slipping down onto the ears and compressing them.

[0049] The rear sections 1-2 of the first fixing belt and 2-2 of the second fixing belt are both made of cloth and can be washed, disinfected and reused.

[0050] Both the front section 1-1 of the first fixation strap and the front section 2-1 of the second fixation strap are made of pressure-resistant material, which is rubber. For example, the rubber layer used as pressure-resistant material has good elasticity and stretchability, which can relieve the pressure of the front section 1-1 of the first fixation strap and the front section 2-1 of the second fixation strap on the patient's cheek skin and prevent pressure sores.

[0051] A flexible fixing ring 5 for securing the gastric tube 7 is fitted onto the first fixing band 1 and / or the second fixing band 2. The flexible fixing ring 5 is made of silicone and is Ω-shaped. It is attached to the first fixing band 1 and / or the second fixing band 2 via a fabric loop 5-1. In this embodiment 1, the flexible fixing ring 5 is fitted onto the first fixing band 1 and can move back and forth along the first fixing band 1, facilitating adjustment of its position. The Ω-shaped flexible fixing ring 5 wraps around the gastric tube 7, and its two legs bind the gastric tube 7 to the first fixing band 1, thus securing the gastric tube 7 and preventing it from pulling downwards below the patient's nose due to its own weight, thus preventing the gastric tube 7 from falling off and ensuring a more secure fixation. In this embodiment 1, the flexible fixing ring 5 made of silicone can better wrap around the gastric tube 7 and the first fixing band 1. After wrapping, the two legs of the flexible fixing ring 5 are made of silicone, and the friction between them can effectively prevent the two legs from separating, thus preventing the gastric tube 7 from falling off the first fixing band 1.

[0052] In this embodiment 1, a method for using a gastric tube traction device is as follows: First, the middle section of the fixing rope 6 is used to tightly fix the gastric tube 7 below the patient's nose. Then, the two ends of the fixing rope 6 are respectively tied to the first fixing strap 1 and the second fixing strap 2 to achieve the connection between the two ends of the fixing rope 6 and the first fixing strap 1 and the second fixing strap 2. Then, the adjusting buttons 2-3 and the corresponding adjusting holes 1-3 are paired and connected so that the first fixing strap 1, the fixing rope 6 and the second fixing strap 2 form a loop that matches the patient's head circumference. Finally, the flexible fixing loop 5 is used to tie the gastric tube 7 body together with the first fixing strap 1 to help fix the gastric tube 7 body.

[0053] See Figures 6 to 7 In specific embodiment 2, a gastric tube traction device is provided. The difference between embodiment 2 and embodiment 1 is that: the front section 1-1 of the first fixing strap is a hollow tube, and the hollow tube-shaped front section 1-1 of the first fixing strap has a first strip-shaped through hole 1-4. One end of the fixing rope 6 is detachably connected to the first strip-shaped through hole 1-4; the front section 2-1 of the second fixing strap is a hollow tube, and the hollow tube-shaped front section 2-1 of the second fixing strap has a second strip-shaped through hole 2-4. The other end of the fixing rope 6 is detachably connected to the second strip-shaped through hole 2-4. This design facilitates the insertion of the corresponding end of the fixing rope 6 into the hollow tube of the first fixing strap 1 and the hollow tube of the second fixing strap 2, and then out through the corresponding strip-shaped through hole. The exiting fixing rope 6 is then knotted and secured in the strip-shaped through hole. By using a knotted method on the same strip-shaped through hole, the length of the fixing rope 6 can be adjusted, and the fixing rope 6 can be easily replaced. For example, without adjusting the adjusting buttons 2-3 and adjusting holes 1-3, the length of the fixing rope 6 can be adjusted and the fixing rope 6 can be replaced.

[0054] See Figures 8 to 10In specific embodiment 3, a gastric tube traction device is provided. This embodiment 3 differs from the previous embodiments in that: a gastric tube traction device includes a first fixing strap 1, a fixing rope 6 for fixing the gastric tube 7, and a second fixing strap 2. The front section 1-1 of the first fixing strap is connected to a first ear protector 3, which is detachably connected to one end of the fixing rope 6. The rear section 1-2 of the first fixing strap is provided with several adjustment holes 1-3. The front section 2-1 of the second fixing strap is connected to a second ear protector 4, which is detachably connected to the other end of the fixing rope 6. The rear section 2-2 of the second fixing strap is provided with adjustment buttons 2-3 that match the adjustment holes 1-3. In this embodiment 3, the functions of the adjustment buttons 2-3 and the adjustment holes 1-3 are the same as those in embodiment 1. The inner surface of the rear section 1-2 of the first fixing strap and / or the inner surface of the rear section 2-2 of the second fixing strap are provided with anti-slip parts A. In this embodiment 3, the function of the anti-slip parts A is the same as that in embodiment 1. The first ear hook 3 and the second ear hook 4 are designed to avoid the patient's ear area, prevent the first fixing strap 1 and the second fixing strap 2 from compressing the ears, and improve the comfort of using the gastric tube traction device.

[0055] Both the first ear protector 3 and the second ear protector 4 are made of wire, which can be reshaped and provide a certain degree of fixed support. The first ear protector 3 is provided with a first mounting ring 3-1 for connecting to one end of the fixing rope 6, which facilitates the disassembly and reassembly of the first ear protector 3 from the first fixing strap 1. The second ear protector 4 is provided with a second mounting ring 4-1 for connecting to the other end of the fixing rope 6, which facilitates the disassembly and reassembly of the second ear protector 4 from the second fixing strap 2, and also allows for easy adjustment of the length of the first fixing strap 1 and the second fixing strap 2 after they are connected.

[0056] The outer surface of the first ear hook 3 is covered with a plastic layer to prevent sweat and reduce the possibility of rust. The outer surface of the second ear hook 4 is also covered with a plastic layer to prevent sweat and reduce the possibility of rust.

[0057] Both the ear-protecting part 3 and the ear-contacting part 4 of the first ear-protecting hook 3 are provided with a sponge layer, such as the first sponge layer 3-3 on the first ear-protecting hook 3 and the second sponge layer 4-3 on the second ear-protecting hook 4. If the first fixing strap 1 and the second fixing strap 2 are slightly loosened, the first ear-protecting hook 3 and the second ear-protecting hook 4 will fall on the corresponding ears, and the corresponding sponge layer will be placed on the corresponding ears, which can relieve the pressure of the first ear-protecting hook 3 and the second ear-protecting hook 4 on the corresponding ears. The sponge layer also has a breathable function.

[0058] The first ear hook 3 has an anti-slip part B3-2 at the end away from the first mounting ring 3-1; the second ear hook 4 has an anti-slip part C4-2 at the end away from the second mounting ring 4-1; the anti-slip parts A, B3-2 and C4-2 are silicone layers; the anti-slip parts B3-2 and C4-2 are attached to the skin of the corresponding ear accessory, increasing the friction between the first ear hook 3 and the second ear hook 4 and the skin, helping to stabilize the position of the corresponding ear hook, ensuring the position of the corresponding ear hook relative to the corresponding ear (for example, the ear hook covers the ear, but does not touch or press on the ear), and ensuring that the corresponding ear hook can protect the corresponding ear.

[0059] The end of the first fixing strap 1-1 is connected to the first ear protector 3 via a first loop 1-5. This connection helps adjust the connection position of the first fixing strap 1 on the first ear protector 3, ensuring that after the first fixing strap 1 and the second fixing strap 2 are tightened, the fixing rope 6, the first fixing strap 1, and the second fixing strap 2 are aligned in a straight line. The end of the second fixing strap 2-1 is connected to the second ear protector 4 via a second loop 2-5. This connection helps adjust the connection position of the second fixing strap 2 on the second ear protector 4, ensuring that after the first fixing strap 1 and the second fixing strap 2 are tightened, the fixing rope 6, the first fixing strap 1, and the second fixing strap 2 are aligned in a straight line. In this embodiment 3, both the first ear protector 3 and the second ear protector 4 are located at the base of the ear behind the auricle. After the gastric tube traction device is tightened (for example, the fixing rope 6, the first fixing strap 1, and the second fixing strap 2 are tightened), the two ear protectors correspond to the corresponding ears, and the ear protectors are pulled open on both sides, increasing the area inside the ear protectors and allowing them to better avoid the ears and protect them.

[0060] The connection between the first fixing strap 1 and the second fixing strap 2, and the two connection points between the first ear protector hook 3, the second ear protector hook 4 and the two ends of the fixing rope 6, can all adjust the tightness of the gastric tube traction device after it is tightened and the length of one loop (for example, the fixing rope 6, the first fixing strap 1 and the second fixing strap 2 are tightened to form one loop).

[0061] See Figures 11 to 12 In specific embodiment 4, a gastric tube traction device is provided. The difference between this embodiment 4 and the previous embodiments is that the first ear protector 3 and the second ear protector 4 are both located at the tragus in front of the auricle, so as to avoid the ear protector from shifting and pressing down on the ear root.

[0062] See Figures 13 to 14In specific embodiment 5, a gastric tube traction device is provided. The difference between embodiment 5 and the previous embodiments is that: the first fixing band 1 is also provided with an upper left auxiliary band 1-6 and a lower left auxiliary band 1-7, and the second fixing band 2 is also provided with an upper right auxiliary band 2-6 and a lower right auxiliary band 2-7. The ends of the upper left auxiliary band 1-6 and the upper right auxiliary band 2-6 are detachably connected by Velcro, and the upper left auxiliary band 1-6 and the upper right auxiliary band 2-6 together form the upper auxiliary band; the ends of the lower left auxiliary band 1-7 and the lower right auxiliary band 2-7 are detachably connected by Velcro, and the lower left auxiliary band 1-7 and the lower right auxiliary band 2-7 together form the lower auxiliary band.

[0063] At the back of the patient's head, upper and lower auxiliary straps are used to add auxiliary fixation above and below the first fixation strap 1 and the second fixation strap 2, tightening from three dimensions. The upper and lower auxiliary straps, as well as the first fixation strap 1 and the second fixation strap 2, fit the back of the patient's head more closely and are suitable for different patients. This ensures that the first fixation strap 1 and the second fixation strap 2 will not slip or come off, and that the first fixation strap 1, the second fixation strap 2, and the fixation rope 6 are always in a taut state, ensuring that the gastric tube 7 below the patient's nose will not fall off, making it more secure.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
