Description

Technical Field

[0001] The invention relates to the field of medical endotracheal cannulas, and in particular to an anti-slip endotracheal cannulas. Background Art

[0002] In the modern medical field, endotracheal intubation is a vital emergency and treatment method. Existing endotracheal intubation usually inserts a tube into the trachea, and uses an air bag to close to the inner wall of the trachea to achieve the purpose of sealing and preventing movement. This method can indeed play a role in preventing slipping to a certain extent.

[0003] However, there are some obvious problems with the current tracheal intubation technology. On the one hand, because the airbag is always in a tight and close state to the trachea, even if lubricated, the airflow impact caused by the patient's swaying or violent coughing will still cause the airbag to move, and then rub against the trachea, causing tracheal wear. On the other hand, when the size of the airbag does not match the caliber of the trachea, especially when the airbag is too close to the trachea, this wear will be further aggravated. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an anti-slip endotracheal tube, which can not only play a guiding role through the guiding support mechanism, but also play a supporting and limiting role for the ring frame three and the elastic tube. The material of the hose one itself is relatively soft, which is inconvenient for the doctor to insert it into the trachea, and the operational convenience is effectively improved. By providing a round block, when the round block is located inside the hose one corresponding to the elastic tube, the elastic tube can be effectively fixed to prevent the doctor from shaking at the elastic tube during operation, thereby increasing the difficulty of operation.

[0025] Preferably: the mouth limiting mechanism comprises:

[0026] There are four air bags, which are fixed at equal intervals on the inner wall of the mouthpiece;

[0027] The hose three is fixed to the outer wall of one side of the mouthpiece and connected to the air hole of the air bag. The outer wall of one end of the hose three is fixedly connected with a cross valve.

[0028] Preferably: the mouth limiting mechanism comprises:

[0029] An L-shaped frame is fixed to the outer wall of one end of the mouthpiece, and a silicone pad is slidably inserted into the other end of the L-shaped frame;

[0030] The traction ropes are provided with two and are respectively fixed at two ends of the silicone pad.

[0031] Beneficial effects of the present invention:

[0032] 1. The guiding support mechanism can not only guide, but also support and limit the ring frame three and the elastic tube. The material of the hose one itself is relatively soft, which is inconvenient for the doctor to insert it into the trachea, which effectively improves the convenience of operation. By providing a round block, when the round block is located inside the hose one corresponding to the elastic tube, the elastic tube can be effectively fixed to prevent the doctor from shaking during the operation of the elastic tube, which increases the difficulty of operation.

[0033] 2. The expansion limit mechanism can effectively limit the end of the hose 1 inside the trachea and seal it, and can also prevent the impact of airflow caused by severe coughing, so that the film is in hard contact with the inner wall of the trachea. The film filled with water can play a certain buffering role. When the film is under pressure, the water inside is squeezed and flows along the hose 2 to the inside of the water cup, thereby reducing the expansion volume. Even if the film is moved by the impact of the airflow, it will not produce a large friction with the inside of the trachea, which effectively improves the safety of use and reduces the discomfort of patients.

[0034] 3. The mouth limit mechanism can be used to limit and fix one end of the hose, and the mouthpiece can protect the hose to prevent it from being bitten by the patient and causing air leakage, which effectively improves the protectiveness of the hose. When the inside of the oral cavity needs to be cleaned, the gas inside the airbag is released, and the plug-in tube is pressed and moved along the trajectory of the silicone pad, which can leave a larger space for the mouth for easy cleaning. At the same time, there is no need to disassemble the mouth limit mechanism, which effectively improves the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

It can also prevent the impact of airflow caused by severe coughing, so that the film 221 is in hard contact with the inner wall of the trachea. The film 221 filled with water can play a certain buffering role. When the film 221 is under pressure, the water inside is squeezed and flows along the hose 211 to the inside of the water cup 212, thereby reducing the expansion volume. Even if the film 221 is moved by the impact of the airflow, it will not generate much friction with the inside of the trachea.

[0046] The guiding and supporting mechanism 300 includes the following parts: the twist block 310 is detachably connected to the plug-in tube 120, a tube core 311 is fixedly connected to the outer wall of the twist block 310, and a round block 320 is fixedly connected to the outer wall of the tube core 311, a traction rope 330 is fixed to the outer wall of one end of the tube core 311, a clamping block 331 is fixedly connected to one end of the traction rope 330, and the outer wall of the clamping block 331 is plugged into the square groove 223, and the outer wall of the clamping block 331 is slidably plugged into the inside of the slide 230. The guiding and supporting mechanism 300 can not only play a guiding role, but also play a supporting and limiting role for the ring frame 3 220 and the elastic tube 111. The hose 110 itself is made of a relatively soft material, which is inconvenient for doctors to insert it into the trachea, thereby effectively improving the convenience of operation.

[0047] The mouth limiting mechanism 400 includes the following parts: the mouthpiece 410 is clamped between the two limiting rods 121 and slides on the outer wall of the hose 110, four air bags 411 are provided and fixed at the inner wall of the mouthpiece 410 at equal intervals, the hose 3 412 is fixed to the outer wall of one side of the mouthpiece 410 and connected to the air hole of the air bag 411, a cross valve 413 is fixedly connected to the outer wall of one end of the hose 3 412, the L-shaped frame 420 is fixed to the outer wall of one end of the mouthpiece 410, a silicone pad 422 is slidably inserted at the other end of the L-shaped frame 420, and two traction ropes 2 430 are provided and fixed at both ends of the silicone pad 422, one end of the hose 110 can be limited and fixed by the mouth limiting mechanism 400, and the mouthpiece 410 can protect the hose 110 at the same time to prevent it from being bitten by the patient and causing air leakage, thereby effectively improving the protectiveness of the hose 110.

[0048] Specifically, during work, the doctor puts on gloves, puts the anti-slip intubation mechanism 100 into a sealed bag and applies a sterile lubricant thereto. After exposing the glottis through a laryngoscope, the doctor takes out the anti-slip intubation mechanism 100 and inserts it into the trachea along the glottis. The guiding support mechanism 300 can guide the hose 110 to be inserted into the trachea in the correct direction, thereby reducing the risk of mis-entering the esophagus or other parts. After insertion, the doctor twists the twist block 310 to separate it from the intubation tube 120, and pulls the guiding support mechanism 300 out of the hose 110. The round block 320 and the elastic tube 111 are partially separated. The elastic tube 111 is separated, and the limit on the elastic tube 111 is released. At the same time, the traction rope 1 330 is pulled, which will drive the block 331 to separate from the square groove 223, and slide along the slide 230 to the inside of the hose 110, pull it out, and release the limit. The limit frame 213 is clamped on the bed frame near the head. The doctor uses a syringe to inject water into the hose 2 211 along one end of the water cup 212. The water will enter the film 221. Under the pressure of the water, the film 221 will expand outward. At this time, the ring frame 3 220 will slide toward the ring frame 2 210 until the film 221 expands to the outer wall and sticks to the air The doctor continuously injects water, causing the water to rise along the hose 211 to the inside of the water cup 212, giving a certain pressure to the film 221, causing its outer wall to stick to the inner wall of the trachea. When the patient coughs violently, a strong airflow impact is generated inside the trachea, and the film 221 is impacted. The water inside is squeezed and flows along the hose 211 to the inside of the water cup 212, thereby removing part of the impact force and reducing the expansion volume of the film 221. Even if the film 221 is impacted by the airflow and moves, it will not generate much friction with the inside of the trachea. When the impact ends, the film 221 is impacted by the elastic tube 11 1 rebounds, so that the film 221 returns to its original position, and the water in the water cup 212 flows back to the inside of the film 221 along the hose 211, so that the outer wall sticks to the inner wall of the trachea. After the film 221 is filled with water, the mouthpiece 410 clamped between the two limiting rods 121 is separated and moved to the patient's teeth to bite it. The doctor uses a syringe to inject gas into the cross valve 413 to expand the airbag 411 and fit it tightly to the corresponding teeth, and the mouthpiece 410 is limited. Then the silicone pad 422 is placed on the philtrum and the traction rope 2 430 is put on the ear to complete the limitation.

[0049] Embodiment 1

[0050] like Figure 4-6As shown, in this embodiment, the expansion limiting mechanism 200 includes the following parts: its ring frame 210 is fixed to the outer wall of the hose 110, and one end of the hose 211 is fixed to the outer wall of the ring frame 210, a water cup 212 is fixedly connected to the other end of the hose 211, and a limiting frame 213 is fixedly connected to the outer wall of the water cup 212, its ring frame 3 220 and the outer wall of the hose 110 are located on one side of the ring frame 112 to slide, a film 221 is fixedly connected between the ring frame 3 220 and the outer wall of the ring frame 210, its sealing member 222 is fixed inside the ring frame 3 220, a square groove 223 is opened on the outer wall of one side of the ring frame 3 220, and the slideway 230 is fixed to the outer wall of the hose 110 at one side of the ring frame 112.

[0051] In this embodiment, after the limit is released, the limit frame 213 is stuck on the bed frame near the head, and the doctor uses a syringe to inject water into the hose 211 along one end of the water cup 212. The water will enter the film 221 and the film 221 will expand outward due to the pressure of the water. At this time, the ring frame 3 220 will slide toward the ring frame 210 until the film 221 expands to the outer wall against the inner wall of the trachea. The doctor continues to inject water to make the water rise along the hose 211 to the inside of the water cup 212, and a certain pressure is applied to the film 221 to make its outer wall against the inner wall of the trachea. When the patient coughs violently, a strong airflow impact will be generated inside the trachea, and the film 221 will be impacted. The water inside will be squeezed and will flow along the hose 211 to the inside of the water cup 212, thereby removing part of the impact force and reducing the expansion volume of the film 221. Even if the film 221 is impacted by the airflow, The film 221 filled with water can play a certain buffering role. When the film 221 is subjected to pressure, the water inside is squeezed and flows along the hose 211 to the inside of the water cup 212, thereby reducing the expansion volume. Even if the film 221 is moved by the impact of the airflow, it will not generate a large friction with the inside of the trachea, thereby effectively improving the safety of use and reducing the discomfort of patients.

[0052] like Figure 2-3As shown, in this embodiment, the guiding support mechanism 300 includes the following parts: its twist block 310 is detachably connected to the plug-in tube 120, a tube core 311 is fixedly connected to the outer wall of the twist block 310, and a round block 320 is fixedly connected to the outer wall of the tube core 311, its traction rope 330 is fixed to the outer wall of one end of the tube core 311, a clamping block 331 is fixedly connected to one end of the traction rope 330, and the outer wall of the clamping block 331 is plugged into the square groove 223, and the outer wall of the clamping block 331 is slidably plugged into the inside of the slide 230.

[0053] During specific implementation, the anti-slip intubation mechanism 100 coated with the coating is taken out and inserted into the trachea along the glottis, wherein the guiding support mechanism 300 can guide the hose 110 to be inserted into the trachea in the correct direction, thereby reducing the risk of mistakenly entering the esophagus or other parts. The guiding support mechanism 300 can not only play a guiding role, but also play a supporting and limiting role for the ring frame 3 220 and the elastic tube 111. The hose 110 itself is made of a relatively soft material, which is not convenient for the doctor to insert it into the trachea, thereby effectively improving the convenience of operation. After insertion, the personnel twist the twist block 310 to separate it from the intubation tube 120, and pull the guiding support mechanism 300 out of the hose 110, and the round block 320 is partially separated from the elastic tube 111, thereby releasing the limit on the elastic tube 111. By providing the round block 320, when the round block 32 When the elastic tube 111 is located inside the hose 110 corresponding to the elastic tube 111, the elastic tube 111 can be effectively fixed to prevent the doctor from shaking at the elastic tube 111 during operation, thereby increasing the difficulty of operation. At the same time, the traction rope 1330 is pulled, which will drive the block 331 to separate from the square groove 223, and then slide along the slide 230 to the inside of the hose 110 to be pulled out. The block 331 is engaged with the square groove 223 to limit the position, thereby preventing the ring frame 320 from contacting the inside of the oral cavity during operation, causing the film 221 to open and expand due to movement, thereby affecting the doctor's operating line of sight, thereby effectively improving the operating stability. In addition, the slide 230 is provided to be slidably connected with the block 331, thereby preventing the block 331 from being thrown away and hitting the inner wall of the trachea during extraction, thereby causing damage to the trachea, thereby effectively improving the safety of use.

[0054] Embodiment 2

[0056] During specific implementation, after the film 221 is filled with water, the mouthpiece 410 clamped between the two limiting rods 121 is separated and moved to the patient's teeth to bite it. The doctor uses a syringe to inject gas into the cross valve 413 to expand the airbag 411 and fit the corresponding teeth, thereby limiting the mouthpiece 410. After the silicone pad 422 is placed on the philtrum, the traction rope 430 is put on the ear to complete the limiting. The end of the hose 110 can be limited and fixed by the mouth limiting mechanism 400. At the same time, the mouthpiece 410 can protect the hose 110 from being bitten by the patient and causing air leakage, thereby effectively improving the protectiveness of the hose 110. When it is necessary to clean the inside of the oral cavity, by releasing the gas in the airbag 411 and pressing the plug-in tube 120 to move along the trajectory of the silicone pad 422, a larger space can be left for the mouth for easy cleaning. At the same time, there is no need to disassemble the mouth limiting mechanism 400, thereby effectively improving the convenience of operation.
