Description

Technical Field

[0001] This utility model belongs to the field of gastric tube technology, specifically relating to a pressure-resistant adjustable gastric tube fixing device. Background Technology

[0002] In the medical field, the use of gastric tubes is very common. Gastric tubes are usually made of polyurethane or silicone. When the patient's head presses on the gastric tube, it is easy to crush the gastric tube.

[0003] To reduce the phenomenon of gastric tubes being crushed, Chinese patent CN212547674U discloses a gastric tube anti-compression fixing device, which includes a gastric tube and an anti-compression tube sleeved on the outside of the gastric tube. The anti-compression tube is harder than the gastric tube, thus avoiding accidental compression and damage to the gastric tube.

[0004] However, in order to effectively reduce the pressure on the gastric tube, the anti-pressure tube is usually made of a relatively rigid material, such as plastic or metal. This makes the shape of the anti-pressure tube difficult to deform, unable to be adjusted according to the patient's needs, and unable to fit the patient well. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable gastric tube fixation device that can reduce the phenomenon of gastric tube being compressed and blocked by the patient's head, while adapting the assembly to the patient's posture.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable pressure-resistant gastric tube fixing device includes a mounting plate and a strap mounted on the mounting plate. A mounting ring is fixedly connected to the upper side of the mounting plate, and a gastric tube body is inserted into the inside of the mounting ring.

[0008] The gastric tube fixing device also includes an anti-pressure tube, one end of which is fixedly connected to the mounting ring, and the gastric tube body is inserted into the inside of the anti-pressure tube;

[0009] The anti-pressure tube includes multiple rigid tubes, and two adjacent rigid tubes are connected by a flexible tube. The gastric tube is inserted inside the rigid tube and the flexible tube, and the length of the rigid tube is greater than the length of the flexible tube.

[0010] The rigid tube is also fitted with a fixing structure that is compatible with the gastric tube.

[0011] Furthermore, the fixing structure includes multiple inflatable air bladders, which are respectively fixedly connected to the inside of multiple rigid tubes. A tube passage is reserved at the axial position of each air bladder, and the gastric tube is inserted into the tube passage.

[0012] Furthermore, two adjacent airbag rings are connected by an air guide hose, and an air nozzle connected to the airbag ring is fixedly connected to the outside of one of the rigid tubes.

[0013] Furthermore, it also includes an elastic strip, which is inserted into the perforation channel of the multiple airbag rings, and the elastic strip is located between the airbag rings and the gastric tube body.

[0014] Furthermore, elastic plates are rotatably connected to both sides of the mounting plate, and an elastic sheet is rotatably attached to the end of the elastic plate away from the mounting plate.

[0015] Furthermore, the end of the elastic plate away from the mounting plate may be threaded with a screw, and the elastic piece is rotatably connected to the lower end of the screw.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This utility model discloses an adjustable pressure-resistant gastric tube fixation device. By improving the structure of the pressure-resistant tube, the pressure-resistant tube is changed into a combination of a rigid tube body and a flexible tube body. The shape of the pressure-resistant tube can be adjusted according to the patient's needs. This can reduce the phenomenon of the gastric tube body being compressed by the patient's head and blocking air, while making the combination body adapt to the patient's posture.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-4 As shown, an adjustable pressure-resistant gastric tube fixation device includes a mounting plate 1 and a strap 2 mounted on the mounting plate 1. The strap 2 can be an elastic band or a flexible band, as long as it can be used to wear the mounting plate 1 on the patient's head. A mounting ring 6 is fixedly connected to the upper side of the mounting plate 1. When the mounting plate 1 is installed at the patient's upper lip, the mounting ring 6 is opposite to the patient's nostrils. A gastric tube body 7 is inserted into the inside of the mounting ring 6, so that the gastric tube body 7 can be directly inserted into the patient's body through the patient's nostrils.

[0026] like Figure 1-3 As shown, the gastric tube fixation device also includes an anti-pressure tube. One end of the anti-pressure tube is fixedly connected to the mounting ring 6. The fixing method can be threaded connection or snap-fit. The gastric tube body 7 is inserted into the anti-pressure tube. At this time, the anti-pressure tube can protect the gastric tube body 7, reduce the pressure of the patient's head on the gastric tube body 7, and reduce the phenomenon of the gastric tube body 7 being crushed by the patient's head and blocked by air.

[0027] The core of this technical solution lies in the fact that the anti-pressure tube includes multiple rigid tubes 8, with adjacent rigid tubes 8 connected by flexible tubes 9. The gastric tube 7 is inserted inside the rigid tubes 8 and the flexible tubes 9. The length of the rigid tubes 8 is greater than the length of the flexible tubes 9, i.e., the length ratio of the rigid tubes 8 to the flexible tubes 9 is preferably 4:1. At this time, the rigid tubes 8 can reduce the pressure on the gastric tube 7 caused by the patient's head. By bending the flexible tubes 9, the two adjacent rigid tubes 8 can be adjusted to different angles. By bending the multiple flexible tubes 9, the positions of the multiple rigid tubes 8 can be adjusted, thereby allowing the anti-pressure tube to be adjusted into different shapes to adapt to the patient's posture.

[0028] Here, the rigid tube 8 can be made of plastic, and the flexible tube 9 can be made of rubber.

[0029] Meanwhile, the rigid tube body 8 is also equipped with a fixing structure that matches the gastric tube body 7. The fixing structure is used to fix the gastric tube body 7. Please refer to [link / reference]. Figure 2-3 As shown, the fixing structure in this technical solution includes multiple inflatable airbag rings 10, which are fixedly connected to the inside of multiple rigid tubes 8. A tube passage is reserved at the axial position of the airbag ring 10, and the gastric tube 7 is inserted into the tube passage. Then, the airbag ring 10 is inflated, which causes the airbag ring 10 to expand. The expanded airbag ring 10 squeezes the outer wall of the gastric tube 7, thus fixing the gastric tube 7. The structural design of the airbag ring 10 can increase the contact area between the airbag ring 10 and the outer wall of the gastric tube 7, disperse the squeezing force caused by the fixing structure on the gastric tube 7, and reduce the phenomenon of the gastric tube 7 being crushed by the airbag ring 10.

[0030] Here, when inflating the gastric tube body 7, an inflation device with pressure monitoring can be used to monitor the squeezing force of the air bladder ring 10 on the gastric tube body 7 during the inflation process, thereby effectively reducing the phenomenon of the gastric tube body 7 being crushed by the air bladder ring 10.

[0031] like Figure 1-3 As shown, two adjacent airbag rings 10 are connected by an air guide hose 11. An air nozzle 12 connected to the airbag ring 10 is fixedly connected to the outside of one of the rigid tubes 8. When the inflation device is connected to the air nozzle 12, air can be directly introduced into all the airbag rings 10, and the air pressure inside the multiple airbag rings 10 can be adjusted synchronously so that the multiple airbag rings 10 maintain the same squeezing force on the gastric tube body 7.

[0032] like Figure 1-3 As shown, in order to reinforce the shape of the anti-compression tube, the gastric tube fixing device may also include an elastic strip 13. The elastic strip 13 can be made of plastic. The elastic strip 13 is inserted into the tube passage of multiple airbag rings 10, and the elastic strip 13 is located between the airbag rings 10 and the gastric tube body 7. When the angle between the two rigid tube bodies 8 changes, the elastic strip 13 will be squeezed, causing the elastic strip 13 to deform. Then, the airbag rings 10 are inflated, and the airbag rings 10 can be positioned by the inflated airbag rings 10. At this time, the elastic strip 13 in contact with the airbag rings 10 is a straight section, and the elastic strip 13 inside the tubular body 9 is a curved section. When the elastic strip 13 is positioned by the airbag rings 10, it can form a positioning force at both ends of the curved section. When both ends of the curved section are positioned, the shape of the curved section can be maintained, thereby reinforcing the shape of the anti-compression tube by the elastic strip 13 with a fixed shape.

[0033] The elastic strip 13 can also be located between the airbag ring 10 and the rigid tube body 8 to reduce direct contact between the elastic strip 13 and the gastric tube body 7.

[0034] Please see Figure 1 and Figure 4 As shown, in order to reduce the phenomenon of the mounting plate 1 being overturned when the anti-pressure pipe is subjected to force, elastic plates 3 are rotatably connected to both sides of the mounting plate 1. An elastic piece 5 is rotatably connected to the end of the elastic plate 3 away from the mounting plate 1. At this time, the mounting plate 1 and the two elastic pieces 5 can form a three-point positioning, which improves the stability of the mounting plate 1 and reduces the phenomenon of the mounting plate 1 being overturned when the anti-pressure pipe is subjected to force.

[0035] Furthermore, the end of the elastic plate 3 away from the mounting plate 1 can be threaded with a screw 4, and the elastic piece 5 is rotatably connected to the lower end of the screw 4 to adjust the distance between the elastic plate 3 and the elastic piece 5, thereby adjusting the pressure applied to the patient's head by the elastic piece 5.

[0036] The working principle of this utility model is as follows:

[0037] The mounting plate 1 is placed on the patient's head using the strap 2, and the mounting plate 1 is positioned on the patient's upper lip, with the mounting ring 6 facing the patient's nostrils. Then, the anti-pressure tube is installed on the mounting ring 6, and the gastric tube body 7 is passed through the anti-pressure tube and the mounting ring 6 and inserted directly into the patient's body through the nostrils.

[0038] Then, by bending the flexible tube 9, the two adjacent rigid tubes 8 can be adjusted to different angles. By bending multiple flexible tubes 9, the positions of multiple rigid tubes 8 can be adjusted, thereby adjusting the anti-pressure tube into different shapes to match the patient's posture. When in use, the rigid tubes 8 can reduce the pressure on the gastric tube 7 caused by the patient's head and reduce the phenomenon of the gastric tube 7 being crushed by the airbag ring 10.

[0039] In summary, this technical solution improves the structure of the anti-pressure tube by changing it into a combination of a rigid tube body 8 and a flexible tube body 9. This allows the shape of the anti-pressure tube to be adjusted according to the patient's needs, reducing the phenomenon of the gastric tube body 7 being compressed by the patient's head and causing air blockage, while also making the combination body adaptable to the patient's posture.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
