Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an emergency airbag for removing esophageal foreign bodies and a using method thereof. Background Art

[0002] As is well known, the esophagus is a part of the digestive tract. It is connected to the pharynx at the upper end, descends along the vertebral bodies of the spine, passes through the esophageal hiatus of the diaphragm and leads into the stomach. Its total length is about 25 cm. Moreover, the esophagus is adjacent to the heart and the large blood vessels connected thereto. As the passage for eating, in daily life, it is often encountered that fish bones or hard bones are stuck in the esophagus. The stuck foreign bodies can pose a hazard to a person's esophagus. If not treated in time, it will cause serious damage to the esophagus. Sometimes, it will pierce into the adjacent heart and the large blood vessels connected thereto. Also, blood vessels and the heart may be accidentally injured during the process of removing esophageal foreign bodies, posing a danger to the patient's life. Currently, the hard directoscope used in otolaryngology to remove esophageal foreign bodies is a hard and straight scope by its own design, and it is easy to damage the throat when entering the throat. There is no soft scope for the non-dilatable esophagus globally.

[0003] Currently, for the situation where a foreign body is stuck in the esophagus, usually a foreign body forceps for the esophageal part is used to clamp out the foreign body or an endoscope is combined to clamp the foreign body. However, these types of foreign body clamps only directly pull out the foreign body outward after grasping it. For larger foreign bodies or foreign bodies inserted deeper, on the one hand, it requires the staff to have higher treatment skills, and on the other hand, it is very easy to accidentally injure the patient's esophagus, and even pierce the esophageal wall, posing a threat to the blood vessels around the esophagus. In severe cases, it will endanger life.

[0004] Therefore, it is necessary to further upgrade the existing esophageal first-aid devices. Summary of the Invention

[0005] Aiming at the deficiencies existing in the above-mentioned prior art, the purpose of the present invention is to provide an emergency airbag for removing esophageal foreign bodies that can safely remove foreign bodies and a using method thereof.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An emergency airbag for removing esophageal foreign bodies includes a catheter. At least one balloon surrounding the catheter is provided on the lower side edge of the catheter. A tongue-like sac is provided at the edge of the lower port of the catheter. A first inflatable tube and a second inflatable tube are attached to the inner tube wall of the catheter. One end of the first inflatable tube extends to the outside of the catheter, and the other end of the first inflatable tube is communicated with the balloon. One end of the second inflatable tube extends to the outside of the catheter, and the other end of the second inflatable tube is communicated with the tongue-like sac.

[0008] Preferably, an annular plane is provided on the outer side surface of the balloon.

[0009] Preferably, a color mark is provided on the inner wall of the lower port of the catheter corresponding to the position where the tongue-like sac is located.

[0010] Preferably, the tongue-like sac is provided with a barb at the tail.

[0011] Preferably, the total length of the catheter is 70 cm and the inner tube diameter is 1.5 cm.

[0012] Preferably, the height of the balloon is 3.0 cm, and the diameter of the balloon after inflation is 2.5 cm - 3.0 cm.

[0013] Preferably, the maximum length of the tongue-like sac after inflation is 0.8 cm - 1.0 cm, the maximum width is 0.5 cm, and the maximum height is 1.0 cm - 2.0 cm.

[0014] A method for using an emergency balloon for removing esophageal foreign bodies includes the following steps:

[0015] Step 1: Insert the endoscope into the catheter in alignment to form a nested structure between the endoscope and the catheter, and then insert the endoscope from the mouth into the esophagus.

[0016] Step 2: Combining the perspective of the endoscope, place the lower port of the catheter above the foreign body, and place the tongue-like sac on the side of the foreign body, so that the foreign body is placed in the middle of the tongue-like sac.

[0017] Step 3: After the placement is completed, first inflate the gas from the first inflatable tube end to gradually expand the balloon, push open the esophageal wall at the foreign body location, and make the part of the foreign body originally inserted into the esophageal wall loose or detached.

[0018] Step 4: When it becomes loose or is about to detach, air can be synchronously inflated from the second inflatable tube to gradually expand the tongue-like sac, forming a supporting effect on the side of the foreign body to prevent the foreign body from falling. However, it should be noted that the tongue-like sac cannot be inflated too much to avoid the foreign body being inserted into the esophageal wall again.

[0019] Step 5: When the foreign body meets the grasping condition, insert the grasping forceps from the endoscope, then grasp the foreign body, and finally discharge the gas in the balloon and the tongue-like sac, and take out the whole from the esophagus to complete the operation.

[0020] Due to the adoption of the above scheme, by setting up the balloon in the present invention, after the balloon is inflated, the soft tissue of the esophageal wall above the foreign body is pushed, so that the foreign body gradually detaches from the soft tissue. In this way, when clamping the foreign body, the damage to the esophageal wall can be reduced, and the clamping work will be safer; at the same time, relying on the setting of the tongue-like sac, it can support the foreign body when necessary to prevent the foreign body from falling.

[0031] like Figures 1 to 7 As shown, the embodiment provides an emergency airbag for removing foreign bodies from the esophagus, comprising a catheter 1, wherein at least one balloon 2 surrounding the catheter 1 is arranged on the side of the lower end of the catheter 1, a tongue-shaped nang 3 is arranged at the edge of the lower port of the catheter 1, a first inflation tube 4 and a second inflation tube 5 are attached to the inner tube wall of the catheter 1, one end of the first inflation tube 4 extends to the outside of the catheter 1, and the other end of the first inflation tube 4 is connected to the balloon 2, one end of the second inflation tube 5 extends to the outside of the catheter 1, and the other end of the second inflation tube 5 is connected to the tongue-shaped nang 3, wherein a valve core 6 can be set for the outer ports of the first inflation tube 4 and the second inflation tube 5, and inflation can be pushed in by a needleless syringe.

[0032] This embodiment mainly adopts the setting of the balloon 2. After the balloon 2 is inflated, it pushes the soft tissue of the esophageal wall above the foreign body, so that the foreign body 101 is gradually separated from the soft tissue. In this way, when clamping the foreign body, the damage to the esophageal wall can be reduced, and the clamping work will be safer. At the same time, relying on the setting of the tongue-like naan 3, it can play a supporting role for the foreign body 101 when necessary to prevent the foreign body from falling.

[0033] When using it, follow the steps below:

[0034] Step 1, inserting the endoscope into the catheter 1 in an aligned manner so that the endoscope and the catheter 1 form a sheath structure, and then inserting the endoscope into the esophagus 100 from the oral cavity;

[0035] Step 2, combining the viewing angle of the endoscope, placing the lower end of the catheter 1 above the foreign body 101, and placing the tongue-like naan 3 on the side of the foreign body 101, so that the foreign body 101 is placed in the middle of the tongue-like naan 3;

[0036] Step 3, after placement is completed, gas is blown in from the first inflation tube 4 to gradually expand the balloon 2, thereby expanding the esophageal wall at the location of the foreign body 101, so that the portion of the foreign body 101 originally inserted into the esophageal wall becomes loose or detached;

[0037] Step 4, when loosening occurs or detachment is about to happen, air can be synchronously injected from the second inflatable tube 5 to gradually inflate the tongue-like sac 3, forming a supporting effect on the side of the foreign body 101 to prevent the foreign body from falling. However, it should be noted that the tongue-like sac 3 cannot be inflated too much to avoid the foreign body 101 being inserted into the esophageal wall again;

[0038] Step 5, when the foreign body 101 meets the grasping condition, a grasping forceps is sent in through the endoscope, and then the foreign body 101 is grasped. Finally, the gas in the balloon 2 and the tongue-like sac 3 is discharged, and the whole is taken out from the esophagus 100 to complete the operation.

[0039] Furthermore, since the outer side of the balloon 2 needs to contact the soft tissue on the esophageal wall after inflation, in order to better and more stably push the soft tissue, an annular plane 7 is provided on the outer side of the balloon 2 in this embodiment. Relying on this annular plane 7, the contact area between the surface of the balloon 2 and the soft tissue can be increased, and the effect of pushing the soft tissue can be improved.

[0040] Of course, it should be noted that the principle of the tongue-like sac 3 supporting the foreign body 101 lies in pushing, so that the other side of the foreign body fits with the esophageal wall, but the force is not too large to insert the foreign body into the esophageal wall again. Of course, in actual situations, the doctor can also, according to the actual situation, choose not to use the tongue-like sac 3, that is, not inflate it. For example, if the foreign body has detached but there is no possibility of falling, the tongue-like sac 3 can not be used at this time.

[0041] Furthermore, when inserting by relying on the endoscope, since the tongue-like sac 3 is flat when not inflated and may not be visible under the endoscope, in order to conveniently know the position of the tongue-like sac 3, a color mark 9 is provided on the inner wall of the lower port of the catheter 1 corresponding to the position of the tongue-like sac 3. Relying on this color mark 9, the orientation of the tongue-like sac 3 can be directly known, and then it can be rotated and adjusted to place the tongue-like sac 3 on the side of the foreign body 101.

[0042] Furthermore, in order to enhance the supporting effect, a barb portion 10 can be provided at the tail of the tongue-like sac 3. However, the establishment of this barb portion 10 is not used when not necessary. Therefore, in the conventional design, there are two models: one without the barb portion 10 and the other with the barb portion 10.

[0043] In addition, for the size setting of each component in this embodiment, the following design requirements can be adopted:

[0044] The total length of the catheter 1 is 70 cm, and the inner tube diameter is 1.5 cm; the height of the balloon 2 is 3.0 cm, and the diameter of the balloon 2 after inflation is 2.5 cm - 3.0 cm; the maximum length of the tongue-like sac 3 after inflation is 0.8 cm - 1.0 cm, the maximum width is 0.5 cm, and the maximum height is 1.0 cm - 2.0 cm. The material can be made of medical silicone material.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
