Description

Technical Field

[0001] The present invention relates to the technical field of gastric tube replacement, and more specifically, to a gastric tube guide for facilitating gastric tube replacement. Background Art

[0002] A gastric tube is a common medical device, usually made of soft and elastic materials such as silicone and rubber. Its main function is to establish a passage from outside the body to the stomach during clinical medical procedures. Gastric tubes are used in various situations. For example, for patients who cannot eat independently, such as those in a coma or suffering from swallowing difficulties due to oral or pharyngeal diseases, medical staff can insert the gastric tube through the nasal cavity or oral cavity, along the esophagus and finally reach the stomach, and then use a syringe or a special nutritional infusion device to inject nutrients, water, drugs, etc. into the stomach through the gastric tube to ensure that the patient can obtain sufficient nutrition and moisture and maintain normal physiological functions of the body;

[0003] Currently, in the field of medical care, gastric tubes are important tools for ensuring the nutritional supply and gastrointestinal function regulation of special patients. For patients who rely on gastric tubes for a long time, regularly replacing the gastric tube is a necessary measure to maintain the treatment effect and medical safety. Due to different gastric tube materials, the replacement cycle varies. Ordinary gastric tubes are replaced once a week, and those made of silicone material should be replaced no more than once a month;

[0004] However, current gastric tube replacement operations face many challenges. When inserting a new gastric tube, a series of steps such as strictly controlling the patient's body position and cleaning and lubricating the nasal cavity need to be done well. In actual operation, the situation of unsuccessful catheterization after repeated attempts often occurs, which causes strong irritation to the nasopharynx, esophagus and gastric mucosa of the patient, brings great pain to the patient, and also has many adverse effects on their psychology and physiology, triggering anxiety, stress reactions, etc. At the same time, when family members witness the patient's pain, their anxiety also increases;

[0005] Furthermore, although replacing the gastric tube is a non-invasive operation, the patient needs to travel back and forth between the hospital and home every time, which not only delays the patient's subsequent treatment process, but also greatly increases the burden on the family members in terms of time, energy and economy. In view of the various drawbacks of the traditional gastric tube replacement method, there is an urgent need for an innovative gastric tube auxiliary guiding device to improve the catheterization success rate, relieve the patient's pain, alleviate the pressure on the family members, and optimize the medical care process. Summary of the Invention

[0006] Aiming at the problem of inconvenient and rapid replacement of gastric tubes in the prior art, the purpose of the present invention is to provide a gastric tube guide for facilitating gastric tube replacement.

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0011] Optionally, the transmission device includes a guide rail. An adjusting component is arranged inside the guide rail. Power components are fixedly connected to the outer sides of the adjusting component. The power components are arranged on both sides of the outer surface of the guide wire and their inner sides are in fitting connection with the outer surface of the guide wire.

[0012] Optionally, the outer end of the communicating thin tube extends outside the gastric tube body and is fixedly connected with a gas supply joint. External threads are arranged on the outer side of the gas supply joint. A convenient tearing strip is fixedly connected to one side of the outer end of the gastric tube body.

[0013] Optionally, the adjusting component includes a lead screw. The lead screw is rotatably connected inside the guide rail. The thread directions at both ends of the lead screw are opposite. The end of the lead screw penetrates through the guide rail. One end of the lead screw penetrates through the guide rail and is fixedly connected with an adjusting handrail. Sliders are threadedly connected to both ends of the lead screw. The outer sides of the sliders are fixedly connected with the power components.

[0014] Optionally, the limiting component includes a connecting belt and a fixing seat. The fixing seats are fixedly connected to the outer surface of the guiding housing at equal intervals. The connecting belts are arranged in an annular array at equal intervals and fixedly connected to the inner bottom of the gastric tube body. Grooves are arranged on both sides of the outer surface of the fixing seat. Reserved grooves are arranged on both sides inside the grooves. A torsion spring is fixedly connected to the inner side of the reserved groove. The inner end of the torsion spring is fixedly connected with a connecting disc. A clamping plate is fixedly installed on the inner side of the connecting disc. Electromagnets are fixedly connected to the four corners on the inner side of the clamping plate. The electromagnets are electrically connected with the electric connection plug through a conducting wire.

[0015] Optionally, an anti-slip substrate is fixedly connected to the inner side of the clamping plate. Anti-slip bumps are fixedly connected to the inner side of the anti-slip substrate at equal intervals. The connecting belt is arranged between the inner sides of each anti-slip substrate.

[0016] Optionally, the side shape of the slider is convex-shaped, the cross-sectional shape of the inner cavity of the guide rail is also convex-shaped, and a wear-resistant gasket is fixedly connected to the outer surface of the slider.

[0017] Optionally, the power assembly includes a mounting frame fixedly connected to the outside of the slider. The mounting frame is slidably connected to the outer surface of the guide rail. A guide wheel is rotatably connected to the inside of the mounting frame, and an annular groove is formed on the outer surface of the guide wheel.

[0018] Optionally, the cross-sectional shape of the annular groove is V-shaped. The inner inclined surface of the annular groove is in fitting connection with the outer surface of the guide wire. A crank is rotatably connected to the top of one mounting frame, and the bottom of the crank is fixedly connected to the top of the guide wheel inside the mounting frame.

[0019] Optionally, circular plates are fixedly connected to both sides of the bottom of the guide rail. A bridge-type handrail is fixedly installed at the bottom of the circular plate, and an anti-slip handrail cover is fixedly connected to the outer surface of the bridge-type handrail.

[0020] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0021] In the above solution, when the gastric tube body needs to be replaced, first insert the guide wire into the new gastric tube body. Then place the guiding shell inside the connecting belt, turn on the power supply to make the electromagnet generate magnetic attraction, drive the clamping plates to move inward. During this process, the torsion spring is compressed, and the clamping plates displace relative to each other to clamp and fix the connecting belt. After the fixation is completed, the new gastric tube body can be installed outside the limiting component and the guide wire. Relying on the toughness of the guide wire and the softness of the gastric tube body, the new gastric tube body is implanted into the patient's body along the old gastric tube body. After the new gastric tube body passes through the old gastric tube body, the annular elastic sac can be inflated by connecting an air pump or blowing manually to fix the gastric tube body in the patient's stomach. Then cut off the power supply of the electromagnet, and the torsion spring resets to push open the clamping plates, and the guide wire is withdrawn. Finally, the old gastric tube body is pulled out by pulling it, and the new gastric tube body is limited by the annular elastic sac, and then the air in the annular elastic sac is discharged. This operation can realize the convenient replacement of the gastric tube body;

[0022] During the implantation of the gastric tube body, the adjusting armrest can be twisted to rotate the lead screw in the guide rail. Since the thread directions at both ends of the lead screw are opposite, it will drive the slider to make a stable reciprocating sliding displacement in the guide rail. The slider drives the mounting bracket to move inward, and then drives the guide wheel to move to both ends of the guide wire. The annular groove on the outer side of the guide wheel has a V-shaped cross-section, and its inner wall can stably fit the outer surface of the guide wire. When the crank is pulled, the guide wheel will rotate due to the fit with the guide wire, thereby driving the guide wire to move forward in the new gastric tube body. Such a design utilizes the cooperation of the crank and the guide wheel, significantly improving the stability of the guide wire implantation, avoiding the problem of scratching the human body due to poor force control during manual installation of the gastric tube body. Using the guide wheel to assist in transmitting the guide wire ensures the stability of the guide wire transmission process and enhances the convenience of the device during the implantation of the gastric tube body;

[0023] During the application of the whole device, the guiding device is adopted to make the replacement operation of the gastric tube body simple and fast. It can effectively utilize the characteristics of the new and old gastric tube bodies and the interaction between components to complete the replacement process. The transmission device uses its unique structure and the transmission relationship between components to provide stable power and support for the movement of the guide wire in the gastric tube body. Moreover, after the implantation of the gastric tube body is completed, only by twisting the adjusting handle, the two guide wheels can be separated, so as to quickly remove the transmission device, providing convenience for the subsequent replacement operation of the gastric tube body. During the replacement process of the whole device, the operation is convenient, which can not only improve the safety and stability of the operation, but also facilitate the user to operate.

[0049] As Figures 1 to 10 shown, an embodiment of the present invention provides a gastric tube introducer facilitating the replacement of a gastric tube, including a conveying device 1, a guiding device 2 and a gastric tube assembly 3. The conveying device 1 is installed at the outer end of the guiding device 2, and the gastric tube assembly 3 is sleeved on the outer surface of the guiding device 2.

[0050] The guiding device 2 includes a guide wire 21 which is hollow inside and has a wire disposed therein. The outer end of the guide wire 21 is fixedly connected to a guiding housing 22. The outer side of the guiding housing 22 is fixedly connected with limiting components 23 at equal intervals. One end of the guide wire 21 away from the guiding housing 22 is fixedly connected to an electrical connection plug 24. The gastric tube assembly 3 is sleeved on the outer surface of the guide wire 21.

[0051] The gastric tube assembly 3 includes a gastric tube body 31 which is sleeved on the outer surface of the guide wire 21. The lower outer surface of the gastric tube body 31 is fixedly connected with an annular elastic sac 32. One side inside the gastric tube body 31 is fixedly connected with a communicating thin tube 33. The outer end of the communicating thin tube 33 extends outside the gastric tube body 31. The conveying device 1 and the guiding device 2 work together, improving the efficiency and stability of gastric tube replacement. The guide wire 21 inside the guiding device 2 is hollow and has a wire inside. This structure gives the guide wire 21 a certain strength and can assist the smooth implantation of the gastric tube body 31. At the same time, the wire can be used to transmit electricity to supply power to components such as the electromagnet 238 inside the guiding housing 22. The limiting components 23 on the outer side of the guiding housing 22 can effectively position the gastric tube assembly 3 to ensure that the gastric tube body 31 maintains an accurate position during implantation and replacement. One end of the guide wire 21 is connected to the electrical connection plug 24, which is convenient for connecting an external power source to provide power for the operation of the guiding device 2. On the gastric tube assembly 3, the gastric tube body 31 is sleeved outside the guide wire 21 and can be smoothly implanted into the patient's body relying on the guidance of the guide wire 21. After the annular elastic sac 32 at the lower end of the gastric tube body 31 is inflated, it can fix the gastric tube body 31 to prevent its displacement. The communicating thin tube 33 provides a channel for the inflation and deflation of the annular elastic sac 32, improving the convenience and reliability of gastric tube replacement.

[0052] Such as Figures 1 to 5 And Figure 8As shown, the conveying device 1 includes a guide rail 11. An adjusting assembly 12 is provided inside the guide rail 11. Power assemblies 13 are fixedly connected to the outer sides of the adjusting assembly 12. The power assemblies 13 are arranged on both sides of the outer surface of the guide wire 21 and their inner sides are in fitting connection with the outer surface of the guide wire 21. The adjusting assembly 12 includes a lead screw 121. The lead screw 121 is rotatably connected inside the guide rail 11. The thread directions at both ends of the lead screw 121 are opposite. The ends of the lead screw 121 penetrate through the guide rail 11. One end of the lead screw 121 penetrates through the guide rail 11 and is fixedly connected to an adjusting handle 123. Slide blocks 122 are threadedly connected to both ends of the lead screw 121. The outer sides of the slide blocks 122 are fixedly connected to the power assemblies 13. When it is necessary to adjust the position of the guide wire 21 to assist in the replacement of the gastric tube, rotate the adjusting handle 123. The adjusting handle 123 drives the lead screw 121 to rotate inside the guide rail 11. Since the thread directions at both ends of the lead screw 121 are opposite and both ends are threadedly connected to the slide blocks 122, the rotation of the lead screw 121 will drive the two slide blocks 122 to move in opposite relative directions inside the guide rail 11. The outer sides of the slide blocks 122 are fixedly connected to the power assemblies 13. Therefore, the movement of the slide blocks 122 will drive the power assemblies 13 to move synchronously. The inner sides of the power assemblies 13 are in contact with the outer surface of the guide wire 21. Through the movement of the power assemblies 13, a force can be exerted on the guide wire 21, thereby pushing the guide wire 21 to move along a predetermined direction. This process not only realizes the precise control of the position of the guide wire 21, but also makes use of the thread fit between the lead screw 121 and the slide blocks 122, making the adjustment process stable and precisely controllable, providing reliable power support and position adjustment functions for the smooth implantation and replacement of the gastric tube.

[0053] As Figure 1 , Figure 2 and Figure 8As shown, the outer end of the connecting thin tube 33 extends outside the gastric tube body 31 and is fixedly connected with a gas supply joint 35. An external thread is provided on the outer side of the gas supply joint 35. A convenient tearing strip 34 is fixedly connected to one side of the outer end of the gastric tube body 31. The side shape of the slider 122 is convex, and the cross-sectional shape of the inner cavity of the guide rail 11 is also convex. A wear-resistant gasket is fixedly connected to the outer surface of the slider 122. The outer end of the connecting thin tube 33 extends outside the gastric tube body 31 and is fixedly connected with the gas supply joint 35. With the external thread provided on its outer side, it can be conveniently and tightly connected with an air pump or other gas supply devices, ensuring that gas can be stably transmitted from the external device to the connecting thin tube 33, and then filled into the annular elastic bladder 32, realizing the stable fixation of the gastric tube body 31 in the patient's stomach. When the gastric tube needs to be removed, the gas in the annular elastic bladder 32 can be discharged through this joint, facilitating the removal of the gastric tube. The convenient tearing strip 34 on one side of the outer end of the gastric tube body 31 provides convenience for the removal of the gastric tube. When the gastric tube body 31 needs to be removed, just pinch the tearing strip to pull out the old gastric tube body 31. At this time, it can assist the operator to quickly take out the gastric tube from the patient's body, reducing the operation difficulty and time. The side of the slider 122 and the inner cavity of the guide rail 11 are both convex. This unique structure enables the slider 122 to not only be accurately positioned when sliding in the guide rail 11, preventing the slider 122 from shifting during movement, but also ensuring a stable sliding effect. The wear-resistant gasket fixedly connected to the outer surface of the slider 122 can effectively reduce the friction between the slider 122 and the guide rail 11, extending the service life of the guide rail 11 and the slider 122.

[0054] As Figure 8As shown, the power assembly 13 includes a mounting frame 131, the mounting frame 131 is fixedly connected to the outer side of the slider 122, the mounting frame 131 is slidably connected to the outer surface of the guide rail 11, the inner part of the mounting frame 131 is rotatably connected to a guide wheel 132, the outer surface of the guide wheel 132 is provided with an annular groove 133, the cross-sectional shape of the annular groove 133 is V-shaped, the inner inclined surface of the annular groove 133 is in contact with the outer surface of the guide wire 21, and a mounting frame The top of the guide rail 131 is rotatably connected to a crank 134, the bottom of the crank 134 is fixedly connected to the top of the guide wheel 132 inside the mounting frame 131, the bottom of the guide rail 11 is fixedly connected to a circular plate 14 on both sides, the bottom of the circular plate 14 is fixedly installed with a bridge handrail 15, the outer surface of the bridge handrail 15 is fixedly connected to an anti-skid handrail cover, the mounting frame 131 is fixed to the outside of the slider 122, and can slide on the outer surface of the guide rail 11, when the slider 122 is driven by the screw rod 121 to move in the guide rail When the guide wheel 132 moves in the rail 11, the mounting frame 131 also moves synchronously therewith. The guide wheel 132 connected to the mounting frame 131 rotates inside, and the V-shaped annular groove 133 provided on the outer side thereof can closely fit the outer surface of the guide wire 21, playing a good guiding role. When the crank 134 is turned, since the bottom of the crank 134 is fixedly connected to the top of the guide wheel 132, the rotation of the crank 134 will drive the guide wheel 132 to rotate synchronously. During the rotation of the guide wheel 132, the V-shaped annular groove 133 and the guide wire 21 are connected. The guide rail 11 is fitted with a force applied to the guide wire 21, which steadily pushes the guide wire 21 to move in the gastric tube body 31, ensuring the accuracy and stability of the guide wire 21 implantation. The circular plates 14 fixed on both sides of the bottom of the guide rail 11 and the bridge armrests 15 below provide the operator with a fulcrum for hand-held operation. The non-slip armrest cover further increases the stability and comfort of holding, making it convenient for the operator to better control the crank 134 when adjusting the position of the guide wire 21, thereby achieving refined operation of the movement of the guide wire 21.

[0055] like Figure 10As shown in the figure, the limiting component 23 includes a connecting belt 231 and a fixed seat 232. The fixed seats 232 are fixedly connected to the outer surface of the guiding housing 22 at equal intervals. The connecting belts 231 are arranged in a ring shape at equal intervals and fixedly connected to the inner bottom of the gastric tube body 31. Grooves 233 are formed on both sides of the outer surface of the fixed seat 232. Reserved grooves 234 are formed on both sides of the inside of the groove 233. A torsion spring 235 is fixedly connected to the inner side of the reserved groove 234. The inner end of the torsion spring 235 is fixedly connected to a connecting disc 236. A clamping plate 237 is fixedly installed on the inner side of the connecting disc 236. Electromagnets 238 are fixedly connected to the four corners of the inner side of the clamping plate 237. The electromagnets 238 are electrically connected to a power connection plug 24 through wires. A non-slip substrate 239 is fixedly connected to the inner side of the clamping plate 237. Non-slip bumps are fixedly connected to the inner side of the non-slip substrate 239 at equal intervals. The connecting belt 231 is arranged between the inner sides of the non-slip substrates 239. When the power connection plug 24 is connected to the power supply, the current is conducted to the electromagnets 238 through the wires, causing them to generate magnetism. At this time, the clamping plate 237 connected by the torsion spring 235 in the groove 233 of the fixed seat 232 moves inward under the magnetic attraction of the electromagnets 238, overcoming the elastic force of the torsion spring 235. The non-slip substrate 239 and the non-slip bumps on the inner side of the clamping plate 237 can increase the friction with the connecting belt 231. Since the connecting belt 231 is located between the inner sides of the non-slip substrates 239, when the clamping plate 237 closes, it can tightly clamp the connecting belt 231, firmly fixing the gastric tube body 31 on the guiding device 2. When it is necessary to release the fixation, the power supply of the power connection plug 24 is cut off, the electromagnets 238 lose magnetism, and the torsion spring 235 returns to its original state, driving the clamping plate 237 to open outward, separating the gastric tube body 31 from the guiding device 2, facilitating subsequent replacement or adjustment operations, and ensuring the stability and reliability of the gastric tube during implantation and replacement.

[0056] The working process of the technical solution provided by the present invention is as follows:

[0057] During the use of this device, the guiding device 2 plays an important role. When it is necessary to replace the gastric tube body 31, first insert the guide wire 21 into the new gastric tube body 31. Then, place the guiding housing 22 between the inner sides of the connecting belts 231, connect the power supply using the power connection plug 24, and control the power supply of the electromagnets 238. After being powered on, the electromagnets 238 will generate magnetism, thereby attracting the inner components and driving the two clamping plates 237 to move inward. During this process, the torsion spring 235 will be compressed and in a tense state. The mutual approach of the clamping plates 237 can assist in completing the clamping and fixing operation of the connecting belt 231. After the connecting belt 231 is fixed, the new gastric tube body 31 can be stably installed outside the limiting component 23 and the guide wire 21.

[0058] With the characteristics of the toughness of the guide wire 21 and the softness of the gastric tube body 31, we can implant the new gastric tube body 31 along the path of the old gastric tube body 31 into the patient's body. When the new gastric tube body 31 successfully passes through the old gastric tube body 31, by connecting the air supply joint 35 at the outer end of the connecting straw to an air pump or directly blowing air with the mouth, the annular elastic sac 32 is urged to inflate and expand. This expansion makes the gastric tube body 31 firmly fixed in the patient's stomach. Subsequently, the power supply of the electromagnet 238 is cut off, and the electromagnet 238 loses its magnetism. Under the reset action of the torsion spring 235, the splint 237 is opened, and the guide wire 21 can be smoothly withdrawn from the gastric tube body 31 again. At this time, by pulling the old gastric tube body 31 located outside the new gastric tube body 31, it can be quickly withdrawn from the patient's body. Because the new gastric tube body 31 has achieved the limit position in the stomach through the inflation of the annular elastic sac 32, the extraction operation of the old gastric tube can be efficiently completed. Finally, the air in the annular elastic sac 32 is discharged using the air supply plug. Thus, in the overall application of this device, the self-replacement of the gastric tube body 31 can be conveniently and quickly realized, and the operation process is relatively convenient.

[0059] In addition, the conveying device 1 also shows unique advantages during the implantation of the gastric tube. When performing the gastric tube implantation operation, by turning the adjustment handrail 123, the lead screw 121 inside the guide rail 11 can be driven to rotate. The rotation of the lead screw 121 will drive the sliders 122 at both ends inside the guide rail 11 to slide. Since the thread directions at both ends of the lead screw 121 are opposite, the sliders 122 can be reciprocally slid in the guide rail 11 synchronously and stably. The sliding of the sliders 122 will drive the mounting frame 131 to move inward, so that the guide wheels 132 on the mounting frame 131 move to both ends of the guide wire 21. The annular groove 133 provided on the outer side of the guide wheel 132 has a unique design, and its cross-sectional shape is V-shaped. The inner wall of the annular groove 133 can closely fit the outer surface of the guide wire 21. By pulling the crank 134, the guide wheel 132 can be driven to rotate. Because the guide wheel 132 is in contact with the surface of the guide wire 21, under the drive of the crank 134, the guide wheel 132 will stably push the guide wire 21 to move forward in the new gastric tube body 31. This way of driving the guide wire 21 to move by driving the guide wheel 132 with the crank 134 can significantly enhance the stability of implanting the guide wire 21 into the patient's body, avoiding the situation of scratching the human body due to the difficult control of the force during the manual implantation of the gastric tube body 31. Using the guide wheel 132 to assist in conveying the guide wire 21 makes the conveying process of the guide wire 21 more stable, greatly improving the convenience and stability of this device during the implantation of the gastric tube. Moreover, after the gastric tube body 31 is implanted, only by turning the adjustment handle, the two guide wheels 132 can be driven to separate, so as to quickly remove the conveying device 1, facilitating the subsequent replacement operation of the gastric tube body 31.
