Description

Technical Field

[0001] The present invention relates to the field of auxiliary medical devices, and particularly to a visual gastric tube facilitating the traction adjustment of a guide wire. Background Art

[0002] The statements herein only provide the background art related to the present invention and do not necessarily constitute the prior art.

[0003] A gastric tube is a flexible tube inserted into the stomach through the nasal cavity or oral cavity, mainly used for nutritional support, drug administration, gastrointestinal decompression or diagnostic examination. It is applicable to patients who are unable to eat independently, have digestive tract obstruction or need to empty gastric contents after surgery, helping to maintain the body's basic needs and promote recovery. When the existing gastric tubes are inserted, most of them rely on the doctor's experience to insert from the nostril into the stomach. During this period, due to certain differences in the organs of each patient, it may cause pain to the patient during the insertion process. Some doctors with less experience may insert the gastric tube into the trachea, causing coughing or other discomfort reactions in the patient, increasing the patient's pain. Although a contrast document, a visual gastric tube implantation system (CN109125090B), also discloses a visual gastric tube, it only relies on the guide wire itself for forced traction and penetration, still prone to esophageal injury, and also requires more experience from doctors for the insertion of the gastric tube.

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the utility model without creative efforts belong to the scope of protection of the utility model.

[0029] Embodiment 1: Refer to Figures 1 to 5 ;

[0030] The present invention discloses a visual gastric tube convenient for guiding wire traction adjustment, including a gastric catheter 01 for feeding. The gastric catheter 01 is made of transparent polyurethane or rubber material to better adapt to different patients and reduce the rejection feeling. A visual sleeve 02 for visualization is sleeved at the bottom end of the gastric catheter 01. A traction wire 05 connected to the visual sleeve 02 is arranged through the gastric catheter 01. The traction wire 05 can drive the visual sleeve 02 to move, and synchronously drive one end of the gastric catheter 01 to move for the insertion of the gastric tube. A shunt tube 04 is connected to one side of the gastric catheter 01, and the other end of the shunt tube 04 is connected to a filter sleeve 03. A conductive wire 06 is embedded in the gastric catheter 01. One end of the conductive wire 06 can be connected to an external power supply to introduce current and supply a small current. The shunt tube 04 is used for feeding through the gastric catheter 01 or performing other required operations as needed. A valve is arranged on the shunt tube 04 to control the on-off of the shunt tube 04.

[0031] In one embodiment, the traction wire 05 is hollow, and a wire group 16 for signal transmission and power supply is arranged through the middle of the traction wire 05. A filling cavity 15 is arranged at the bottom end of the gastric catheter 01. The traction wire 05 is composed of multiple thin steel wires wound around each other, making it have rigidity in a certain direction and flexibility in other directions. The wire group 16 is composed of multiple mutually insulated circuits to realize power supply and signal transmission, and further enable the signal of the visual sleeve 02 to be transmitted.

[0032] In one embodiment, the visible sleeve 02 includes a clamping sleeve 14 connected to the gastric catheter 01. The clamping sleeve 14 is provided with two concentric inner and outer annular rings. The two annular rings are sleeved with the gastric catheter 01 therebetween. One side of the clamping sleeve 14 is fixedly connected to a hollow support plate 13. One side of the support plate 13 is detachably connected to a flexible fluoroscopy head 11. A protective ring 27 is connected to the top end of the fluoroscopy head 11. A camera 23 is arranged inside the protective ring 27. An annular flexible LED light 21 is also connected inside the protective ring 27. A traction wire 05 is sleeved with the support plate 13. Multiple connecting grooves are arranged between the clamping sleeve 14 and the gastric catheter 01. The contact area between the clamping sleeve 14 and the filling cavity 15 is increased through the connecting grooves, thereby ensuring the connection between the two. The flexible LED light 21 emits light when powered on, providing a light source for the shooting of the camera 23, performing a visualized intubation operation, facilitating the medical staff to quickly intubate, and reducing the pain of the patient.

[0033] In one embodiment, the filling cavity 15, the clamping sleeve 14, and the support plate 13 are all filled with an ionic electroactive polymer that undergoes a state change when powered on. The ionic electroactive polymer hardens when powered on, thereby making the support plate 13, the clamping sleeve 14, and the bottom end of the gastric catheter 01 hard, ensuring the advancement of the gastric catheter 01 tube, and at the same time ensuring the stability of the clamping between the clamping sleeve 14 and the filling cavity 15. The ionic electroactive polymer adopts a Nafion membrane plated with platinum / gold electrodes, and its stiffness can change with ion migration at a low voltage (1 - 5V).

[0034] In one embodiment, a flexible stabilizing plate 25 is further connected to the bottom of the protective ring 27. A connector is connected to the stabilizing plate 25 through a wire. One end of the connector is electrically connected to the wire group 16, and the other end is electrically connected to a processing panel 22 located on the stabilizing plate 25. A sleeve pipe 20 that is hermetically sleeved with the traction wire 05 is connected to the side of the stabilizing plate 25 away from the camera 23. An elastic piece 19 fixedly connected to the stabilizing plate 25 is further arranged on the outer side of the sleeve pipe 20. One side of the elastic piece 19 abuts against one side of the connecting sleeve 18. The stabilizing plate 25 seals the protective ring 27, thereby hermetically protecting the internal camera 23, processing panel 22, and flexible LED light 21 to ensure its subsequent reuse. The sleeve pipe 20 is sleeved with the traction wire 05, thereby ensuring the overall removal of the fluoroscopy head 11 driven by the traction wire 05 subsequently.

[0035] In one embodiment, a connecting sleeve 18 is connected to the side of the support plate 13 away from the gastric catheter 01. The outer side of the connecting sleeve 18 is sleeved with the fluoroscopy head 11. The support plate 13 and the fluoroscopy head 11 have the same diameter. Corresponding and interconnected mounting holes 12 are provided on the connecting sleeve 18 and the fluoroscopy head 11. A rubber plug for connection is press-fitted in the mounting hole 12. The connecting sleeve 18 can be flexibly sleeved on the fluoroscopy head 11, and at the same time, using its material properties, it is extruded and mounted on the fluoroscopy head 11 to realize the connection between the fluoroscopy head 11 and the support plate 13.

[0036] In one embodiment, a flexible raised ring 17 is sleeved on the outer side of the traction wire 05. The raised ring 17 is sleeved with the support plate 13. The raised ring 17 further connects the traction wire 05 and the support plate 13 to ensure subsequent extraction.

[0037] In one embodiment, the traction wire 05 is sleeved into the gastric catheter 01, then the protective ring 27 with the stabilizing plate 25 is sleeved and placed into the fluoroscopy head 11. Then, the wire on the stabilizing plate 25 is drawn out and connected to the wire group 16 through the connector. At this time, the support plate 13 is sleeved on the fluoroscopy head 11, and a connection is formed between the connecting sleeve 18 and the fluoroscopy head 11. Then, a collection bucket 26 is placed in the middle of the support plate 13, and the protective ring 27 is inserted into the mounting hole 12 to realize the connection between the support plate 13 and the fluoroscopy head 11. At this time, one end of the traction wire 05 is inserted into the sleeve pipe 20 so that the raised ring 17 is sleeved with the support plate 13. Finally, the gastric catheter 01 is pressed to connect the gastric catheter 01 and the clamping sleeve 14 to complete the installation. After the installation is completed, the mounting hole 12, the clamping sleeve 14, and the filling cavity 15 are energized to cure the internal material, strengthen the stiffness of the support plate 13, the clamping sleeve 14, and the top end of the gastric catheter 01, and ensure the insertion of the front end. After the power-on is completed, the fluoroscopy head 11 is inserted into the patient's nostril. At the same time, according to the signal transmitted from the wire group 16 connected to the outside, the position of the entire gastric catheter 01 is monitored in real time. The traction wire 05 is rotated to adjust the position of the fluoroscopy head 11. When the top end of the gastric catheter 01 reaches the stomach, the support plate 13 and the clamping sleeve 14 are powered off at this time, so that the support plate 13 and the clamping sleeve 14 return to the flexible state. At this time, the traction wire 05 is inserted and pulled out, causing the clamping sleeve 14 and the support plate 13 to deform, so that the connection between the clamping sleeve 14 and the gastric catheter 01 is separated. At the same time, under the action of a relatively large insertion and extraction force, the fluoroscopy head 11 also deforms and enters the gastric catheter 01, and then moves out of the body along the gastric catheter 01. During the movement of the fluoroscopy head 11, a vacuum is generated in the gastric catheter 01, which drives the internal gastric juice to move upward to further detect the damage of the pipeline. When reaching the shunt pipe 04, the outside air passes through the filtration of the filter sleeve 03 and enters the gastric catheter 01, and the pressure causes the gastric juice to return to complete the intubation work.

[0038] Embodiment 2: AsFigures 1 - 8 As shown, the difference between this embodiment and the first embodiment lies in the different ways of inserting the gastric catheter 01;

[0039] In this embodiment, it further includes a control sleeve 30 arranged outside the gastric catheter 01. One side of the control sleeve 30 is rotatably sleeved with a rotating ring 37, and the rotating ring 37 is sealingly sleeved with the gastric catheter 01. A battery 34 for power supply and a processor 33 for data control and processing are arranged in the control sleeve 30. A regulation unit connected to the traction wire 05 is also arranged in the control sleeve 30. The regulation unit is used to control the length of the extension of the traction wire 05, so that the gastric catheter 01 extends into the stomach. The control sleeve 30 is encapsulated. When the rotating ring 37 rotates, the gastric catheter 01 does not rotate. The regulation unit makes the traction wire 05 extend or contract to regulate the distance. At the same time, when the control sleeve 30 is rotated by hand, it drives the traction wire 05 to rotate a certain angle, and then drives the gastric catheter 01 to rotate to adapt to the movement of the gastric catheter 01 along a certain track in the esophagus.

[0040] In the second embodiment, the regulation unit includes a first motor 39 fixedly connected to the control sleeve 30. The output end of the first motor 39 is connected to a rotating tube 35 rotatably connected to the control sleeve 30 through a worm and gear transmission. One end of the rotating tube 35 is connected to the traction wire 05. One side of the rotating tube 35 is communicated with an air pump located in the control sleeve 30. Driven by the first motor 39, the rotating tube 35 can rotate in different directions, so as to wind or deliver the traction wire 05, push the traction wire 05 or retract the traction wire 05 to realize feeding and material collection.

[0041] In the second embodiment, a control button 31 electrically connected to the processor 33 is further arranged on the control sleeve 30, and a display screen 32 electrically connected to the processor 33 is also arranged on one side of the control sleeve 30. The control button 31 facilitates the operation of medical staff, and the display screen 32 displays internal images and other data.

[0042] In the second embodiment, a second motor is further arranged in the control sleeve 30. The output end of the second motor is drivingly connected to a mounting shaft 38. One end of the mounting shaft 38 away from the second motor is fixedly connected to a driving roller 36 in contact with the outer wall of the traction wire 05. Friction grooves for increasing friction are arranged on the driving roller 36. Driven by the second motor, the mounting shaft 38 can rotate, and further drive the driving roller 36 to rotate, so as to push the traction wire 05 forward through relative friction.

[0043] In the second embodiment, the traction wire 05 is a hollow tubular structure formed by winding multiple stainless steel wires that are helically sleeved with each other. Flexible sealing layers are connected to both the inner and outer walls of the hollow traction wire 05 through injection molding. A guiding groove that matches the friction groove is provided on the sealing layer located on the outer side. By plastic-sealing the traction wire 05, while ensuring that the traction wire 05 remains a flexible structure, overall sealing is achieved, and thus when air is passed through later, the stiffness maintained under the action of air pressure can be stably maintained.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0045] It should be noted that if there are directional indications such as up and down in the embodiments of the utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly.

[0046] In addition, the meaning of "and / or" that appears throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, if there are descriptions such as "first" and "second" in the embodiments of the utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
