Description

Technical Field

[0001] The utility model relates to the technical field of tracheal intubation auxiliary equipment, in particular to a connector for tracheal intubation. Background Art

[0002] Endotracheal intubation refers to the insertion of an endotracheal tube into the patient's trachea through the mouth or nasal cavity to assist the patient's breathing, relieve airway obstruction, and absorb tracheal secretions. It is often used for patients with general anesthesia, airway obstruction, and excessive airway secretions that cannot be cleared by themselves. According to existing intubation methods, oral endotracheal intubation is more common. Due to its thicker tube diameter, it can absorb secretions in the airway and is very suitable for emergency rescue. Before inserting the tube into the trachea, a connector is needed to open and connect the patient's mouth, throat and airway to enable the tube to be inserted into the airway.

[0003] However, when using existing connectors for endotracheal intubation, the diameter of the connector end is usually unchangeable and the material is usually hard. Therefore, the connector end is easy to scratch the glottis in the throat when it is passed into the patient's airway, causing the patient to easily experience hoarseness and choking when eating after surgery. In addition, when the existing connector is inserted into the catheter, the diameter of the catheter is smaller than the diameter of the connector, which makes the catheter more likely to shake when inserted into the connector. The catheter is easily rubbed against the inner wall of the connector due to the large shaking, resulting in a time-consuming process of the catheter sliding in the connector, which is not conducive to medical staff to perform rapid intubation during emergency rescue. Utility Model Content

[0004] The purpose of the present utility model is to provide a connector for endotracheal intubation to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connector for endotracheal intubation, comprising a horizontal plate, a first inner tube is provided in the middle of the horizontal plate, two half rings are provided on the top of the first inner tube, one end of the half ring is fixedly connected to a clamping rod, the bottom end of the clamping rod is sleeved with a ratchet, the outer side of the ratchet is engaged with ratchet teeth, the bottom end of the first inner tube is sleeved with a hose, the bottom end of the hose is penetrated by a second inner tube, the bottom end of the horizontal plate is fixedly connected to a bite ball, the bottom end of the bite ball is penetrated by an outer tube, the bottom end of the outer tube is sleeved with a telescopic bend, the bottom end of the telescopic bend is sleeved with a conical sleeve, and a conical spring is embedded in the inner side of the conical sleeve.

[0006] Preferably, circular holes are provided on both sides of the top end of the transverse plate, and a hoop passes through the inside of the circular hole, and the hoop is movably connected to the transverse plate through the circular hole.

[0007] Preferably, both sides of the top end of the first inner tube are fixedly connected with ear plates, and the top ends of the ear plates are fixedly connected with vertical rods.

[0008] Preferably, the ratchet is movably embedded in the vertical rod, the clamping rod is movably connected to the vertical rod through the ratchet and the ratchet wheel, and the semi-ring is movably connected to the first inner tube through the clamping rod.

[0009] Preferably, two slots are provided on the top of the transverse plate, the ear plates are movably embedded in the slots and connected, and the first inner tube is movably connected to the transverse plate through the slots.

[0010] Preferably, a through hole is opened in the middle of the bite ball, and the first inner tube is movably connected to the bite ball through the through hole.

[0011] Preferably, the hose and the second inner tube are movably connected to the telescopic elbow and the cone sleeve respectively through the first inner tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The connector for endotracheal intubation, through the first inner tube, the hose, the second inner tube, the tapered sleeve and the tapered spring, makes the diameter of the end of the connector smaller than the diameter of the head end of the connector, so that the small-diameter end can be smoothly inserted into the patient's airway and then pass through the glottis. Then, the bottom end of the tapered spring in the tapered sleeve is expanded through the inner tube, so that the diameter of the end of the connector is restored to the same state as the diameter of the head end of the connector. This method can avoid direct contact between the thicker and harder part of the connector and the patient's glottis, thereby reducing the probability of the patient's glottis being scratched by the connector and reducing the probability of the patient suffering from hoarseness and choking when eating after surgery.

[0014] 2. The connector for endotracheal intubation uses a half ring, a clamping rod, a ratchet and ratchet teeth to restrict the catheter inserted into the connector to the middle of the connector pipe before sliding into the connector. This makes it difficult for the catheter to shake significantly on the inner wall of the connector, reduces the probability of large friction between the catheter and the inner wall of the connector, thereby shortening the time it takes for the catheter to pass through the connector, making it easier for medical staff to perform rapid intubation during emergency rescue.

[0023] like Figures 1 to 4As shown, the connector for endotracheal intubation in this embodiment includes a transverse plate 6. Both ends of the transverse plate 6 are passivated and are safer to use. A first inner tube 5 is provided in the middle of the transverse plate 6. The top of the first inner tube 5 protrudes from the top of the transverse plate 6, so that the first inner tube 5 can be pushed into the outer tube 9, thereby realizing the first inner tube 5 pushing the hose 16 and the second inner tube 17. Two half rings 2 are provided on the top of the first inner tube 5. After the two half rings 2 are combined into a circular ring structure, both ends of the half rings 2 are not tightly attached, so that the half rings 2 can be turned away from one side of the catheter when the connector is pulled out of the patient's mouth, thereby reducing interference with the catheter. One end of the half ring 2 is fixedly connected with a clamping rod 12, which can support and fix the half ring 2. The bottom end of the clamping rod 12 is provided with a ratchet 13, and the outer side of the ratchet 13 is engaged with a ratchet 14. The ratchet 14 can limit the rotation of the ratchet 13, so that the clamping rod 12 can maintain a relatively static state with the vertical rod 3 when not subjected to external force, reducing the probability of the clamping rod 12 driving the half ring 2 to rotate at will. The bottom end of the first inner tube 5 is provided with a hose 16. The hose 16 is made of a material with good flexibility, which can make the second inner tube 17 smoother when passing through the outer tube 9 and the telescopic hose 16. The bottom end of the hose 16 penetrates There is a second inner tube 17, the diameter of the second inner tube 17 is equal to the diameter of the first inner tube 5, and the diameter of the second inner tube 17 is larger than the inner diameter of the cone sleeve 11. The bottom end of the cross plate 6 is fixedly connected with a bite ball 8, which is made of hard plastic and has a ball diameter larger than the diameter of the outer tube 9. The function of the bite ball 8 is to expand the patient's mouth to prevent the patient's teeth from biting the wall of the connector and causing the inner diameter of the connector to become smaller, so that the first inner tube 5 can slide smoothly in the outer tube 9. The bottom end of the bite ball 8 is penetrated by the outer tube 9, and the inner diameter of the outer tube 9 is larger than the outer diameter of the first inner tube 5, so that the first inner tube 5 can pass through the outer tube 9 into the telescopic elbow 10 The bottom end of the outer tube 9 is provided with a telescopic elbow 10. The telescopic elbow 10 is a pipe that can be bent and deformed, so that the connector can smoothly turn and penetrate into the airway from the throat. The bottom end of the telescopic elbow 10 is provided with a cone sleeve 11. The cone sleeve 11 is made of medical soft silicone with a soft texture. The outer diameter of the bottom end is smaller than the outer diameter of the top end, making it easier for the cone sleeve 11 to pass through the patient's throat and glottis, reducing the probability of the connector causing abrasions on the patient's glottis. A conical spring 15 is embedded in the inner side of the cone sleeve 11. The conical spring 15 can keep the cone sleeve 11 thick at the top and thin at the bottom, so that the cone sleeve 11 can smoothly pass through the patient's throat.

[0024] Specifically, circular holes 18 are provided on both sides of the top of the horizontal plate 6, and a hoop 1 is passed through the inside of the circular hole 18. The hoop 1 is movably connected to the horizontal plate 6 through the circular hole 18. The function of the circular hole 18 is to fix the two ends of the hoop 1. The hoop 1 is an elastic retractable belt that can be put on the back of the patient's head, so that the horizontal plate 6 is better fixed to the patient's mouth.

[0025] Furthermore, ear plates 4 are fixedly connected to both sides of the top of the first inner tube 5, and the top of the ear plates 4 is fixedly connected to the vertical rod 3. The ear plates 4 can limit the top of the first inner tube 5, so that the top of the first inner tube 5 is not easy to slide into the outer tube 9, thereby increasing the protection of the first inner tube 5.

[0026] Furthermore, the ratchet 14 is movably embedded in the vertical rod 3, the clamping rod 12 is movably connected to the vertical rod 3 through the ratchet 14 and the ratchet wheel 13, and the half ring 2 is movably connected to the first inner tube 5 through the clamping rod 12. The engagement of the ratchet wheel 13 and the ratchet 14 can make the clamping rod 12 more stable when rotating on the vertical rod 3, thereby reducing the probability of the clamping rod 12 rotating at will.

[0027] Furthermore, two slots 7 are provided at the top of the transverse plate 6, and the ear plate 4 is movably embedded in the slots 7. The first inner tube 5 is movably connected to the transverse plate 6 through the slots 7. The slots 7 can limit the ear plate 4 so that the top of the first inner tube 5 and the top of the transverse plate 6 can be flush, thereby avoiding the situation where the first inner tube 5 protrudes from the transverse plate 6 and is accidentally pulled out.

[0028] Furthermore, a through hole is opened in the middle of the biting ball 8, and the first inner tube 5 is movably connected with the biting ball 8 through the through hole. The outer diameter of the first inner tube 5 is adapted to the inner diameter of the through hole. At the same time, the through hole can make the interior of the biting ball 8 communicate with the interior of the outer tube 9, thereby facilitating the first inner tube 5 to penetrate into the biting ball 8 and the outer tube 9.

[0029] Furthermore, the hose 16 and the second inner tube 17 are movably connected to the telescopic elbow 10 and the cone sleeve 11 respectively through the first inner tube 5. The hose 16 can push the second inner tube 17 to slide toward the bottom end inside the cone sleeve 11, so that the conical spring 15 in the cone sleeve 11 can be expanded by the second inner tube 17, thereby facilitating the passage of the catheter.

[0030] The method of use of this embodiment is as follows: when using the connector for endotracheal intubation, it is necessary to first insert the cone sleeve 11 at the bottom end of the connector from the patient's mouth, and then as the cone sleeve 11 goes deeper, the telescopic elbow 10 can be bent to deform the telescopic elbow 10 so that the cone sleeve 11 can enter the patient's throat, and then continue to push the cone sleeve 11 inward to allow the outer tube 9 to enter the patient's mouth. At this time, after the cone sleeve 11 passes through the glottis at the patient's throat, the end of the cone sleeve 11 will enter the airway, and then push the first inner tube 5 so that the first inner tube 5 drives the soft tube 16 and the second inner tube 17 to slide from the outer tube 9 into the telescopic elbow 10, and then enter the cone sleeve 11, so that The second inner tube 17 stretches the end of the conical spring 15 in the cone sleeve 11 so that the inner diameter of the end of the cone sleeve 11 is the same as the inner diameter of the first inner tube 5. Then the cuff 1 is put on the back of the patient's head so that the patient's teeth bite the bite ball 8 at the bottom end of the horizontal plate 6. Then the catheter can be inserted into the first inner tube 5. At this time, the catheter needs to be inserted into the circular ring structure composed of the two half rings 2. After the catheter is inserted into the airway through the connector, one of the half rings 2 can be rotated so that the half ring 2 is rotated away from the outside of the catheter along the vertical rod 3 through the clamping rod 12. When the two half rings 2 are away from the outside of the catheter, the connector can be pulled out of the patient's mouth, and finally the connector is separated from the catheter.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
