Description

Technical Field

[0001] The utility model relates to the technical field of medical airway auxiliary equipment, in particular to a guiding tracheal catheter. Background Technique

[0002] A tracheal catheter is a commonly used consumable for controlling the airway during general anesthesia, and is widely used in clinical anesthesia, non-invasive ventilators, and cardiopulmonary resuscitation. It is also one of the medical consumables often used by medical staff in clinical work. Especially, it is widely used in clinical general anesthesia and is the preferred medical consumable for maintaining the patient's respiration during general anesthesia.

[0003] In clinical medical work, the traditional tracheal catheter has the following deficiencies during intubation:

[0004] 1. When the tracheal catheter enters the oropharynx and larynx, it often cannot be inserted into the glottis due to shaping reasons and needs to be reshaped with the help of a stylet.

[0005] 2. The tracheal catheter cannot be finely adjusted left and right or up and down in the oropharynx to be inserted into the glottis.

[0006] Therefore, due to the deficiencies in the design concept of the traditional tracheal catheter, the shaping and fine adjustment of the front end of the tracheal catheter are insufficient, increasing the difficulty of tracheal intubation and the anesthetic risk of the patient.

[0007] Chinese Patent CN215024529U discloses a new type of air-conducting catheter. A catheter joint for connecting a respirator is embedded at the tail end of the air-conducting tube. A set of fixing airbags are arranged at both the head and tail ends of the air-conducting tube. The fixing airbags are communicated with an inflation thin tube connected to one side of the air-conducting tube. The tail end of the inflation thin tube is connected with a one-way inflation valve. The fixing airbags include an oral airbag and an airway airbag, which are respectively fixed on the air-conducting tube at positions corresponding to the patient's oral cavity and airway. The overall stability of the air-conducting tube in the patient's oral cavity, larynx and airway is achieved through the inflation of the fixing airbags, reducing the friction between the air-conducting tube and the patient's tissues during the operation, reducing postoperative complications, accelerating the patient's postoperative recovery, and also fixing the patient's tongue and jaw to prevent the patient from biting himself in an unconscious state during the operation. During facial plastic surgery, it can also play a good fixing and supporting role for the patient's face, facilitating the operation, and has good development prospects.

[0008] The above-mentioned patent has two airbags, namely an oral airbag and an airway airbag, on the air-conducting tube, which improves the overall stability of the air-conducting tube in the patient's oral cavity, larynx and airway and reduces the friction between the air-conducting tube and the patient's tissues during the operation. However, during preoperative intubation, when the tracheal catheter enters the oropharynx and larynx, it often cannot be inserted into the glottis due to shaping reasons and needs to be repeatedly inserted into the throat, increasing the difficulty of tracheal intubation, the intubation risk and the damage to the patient's throat. Summary of the Utility Model

[0009] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to propose a guiding tracheal catheter. By setting a pull bar, a slideway and a slide bar, when intubating, the front end part of the tracheal catheter body can be appropriately adjusted left and right and up and down, avoiding repeated intubation and solving the problem of damage to patients caused by repeated intubation.

[0010] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0011] A guiding tracheal catheter, including a tracheal catheter body. The tracheal catheter body is arranged in an arc shape. Four slide bar channels are evenly arranged on the outer wall of the tracheal catheter body. The four slide bar channels are arranged left and right and front and back along the radian direction of the tracheal catheter body. One end of the tracheal catheter body is fixed with a limiting member. Four slide bars are slidably connected in the four slide bar channels. One end of the four slide bars is fixed on the limiting member, and the other ends of the four slide bars extend out of the slide bar channels and are fixedly connected with a pulling member at the end. One side of the limiting member close to the slide bar channel abuts against an inflatable balloon. The inflatable balloon is sleeved and fixed on the tracheal catheter body. One end of the slide bar channel close to the limiting member is located inside the inflatable balloon. The inflatable balloon is connected with a one-way inflation valve through an inflation pipeline. One end of the inflation pipeline close to the inflatable balloon is arranged along the outer wall of the tracheal catheter body.

[0012] Preferably, an oblique incision is provided at the end of the tracheal catheter body close to the limiting member, and a standard joint is fixedly connected to the end of the tracheal catheter body far from the limiting member.

[0013] Preferably, a scale module is further provided on the outer wall of the tracheal catheter body.

[0014] Preferably, a tracheal pharyngeal end side hole is opened on the tracheal catheter body between the oblique incision and the limiting member. The tracheal pharyngeal end side hole is oval.

[0015] Preferably, the included angle between the oblique incision and the cross section of the tracheal catheter body is 45°.

[0016] Preferably, the pulling member is circular, and a crossed cross member is arranged in the middle of the circular shape of the pulling member. The ends of the cross member of the pulling member are fixedly connected with the ends of the four slide bars far from the inflatable balloon in a uniformly distributed manner.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0027] Embodiment

[0028] As Figures 1 to 4 shown, a guiding tracheal catheter includes a tracheal catheter body 1, the tracheal catheter body 1 is arranged in an arc shape, and four slide channels 3 are evenly arranged on the outer wall of the tracheal catheter body 1. The four slide channels 3 are arranged left and right and front and rear along the arc direction of the tracheal catheter body 1; one end of the tracheal catheter body 1 is fixed with a limiting member 9; four slide bars 8 are slidably connected in the four slide channels 3, one end of the four slide bars 8 is fixed on the limiting member 9, and the other ends of the four slide bars 8 extend out of the slide channels 3 and are fixedly connected with a pulling member 12 at the ends; a balloon 4 is abutted against one side of the limiting member 9 close to the slide channels 3, the balloon 4 is sleeved and fixed on the tracheal catheter body 1, and one end of the slide channel 3 close to the limiting member 9 is located inside the balloon 4; the balloon 4 is connected with a one-way inflation valve 7 through an inflation pipeline 6, and one end of the inflation pipeline 6 close to the balloon 4 is arranged in a manner of fitting the outer wall of the tracheal catheter body 1.

[0029] During use, insert one end of the tracheal tube body 1 close to the inflation balloon 4 into the patient's throat. When the intubation through the glottis is not smooth, simply hold the cross member of the pulling member 12 and slightly pull the sliding bar 8 through the pulling member 12 for adjustment. The other end of the sliding bar 8 moves slightly left and right and up and down, realizing the micro-adjustment of the front section of the tracheal tube body 1 left and right or up and down, enabling the smooth intubation of the front end of the tracheal tube body 1, avoiding repeated intubation caused by taking out the tracheal catheter and reshaping it during the intubation process, improving the success rate of intubation, and reducing the risk of intubation and the injury to the patient's throat.

[0030] The tracheal catheter is made of silicone rubber or PVC material. The limiting member 9 is used to limit the inflation balloon 4. At the same time, one end of the sliding bar 8 is fixed on the limiting member 9, or one end of the sliding bar 8 can be clamped and fixed between the tracheal tube body 1 and the limiting member 9 through the limiting member 9. The one-way inflation valve 7 can inflate and deflate the inflation balloon 4 through the inflation pipeline 6 to achieve the appropriate plugging purpose and the function of adjusting the pressure inside the inflation balloon 4.

[0031] In this embodiment, an oblique incision 11 is provided at the end of the tracheal tube body 1 close to the limiting member 9, and a standard joint 2 is fixedly connected to the end of the tracheal tube body 1 far from the limiting member 9.

[0032] The standard joint 2 is used to connect to an external breathing apparatus. It should be noted that the pulling member 12 is made of a hard material, and the sliding bar 8 is made of a soft material. The setting of the pulling member 12 will not interfere with the connection between the standard joint 2 and the external breathing apparatus.

[0033] In this embodiment, a scale module 10 is further provided on the outer wall of the tracheal tube body 1.

[0034] The scale module 10 can accurately control the insertion depth during intubation, which helps to monitor the position of the tracheal catheter.

[0035] In this embodiment, a tracheal pharyngeal end side hole 5 is opened on the tracheal tube body 1 between the oblique incision 11 and the limiting member 9, and the tracheal pharyngeal end side hole 5 is oval.

[0036] The oval tracheal pharyngeal end side hole 5 can increase the ventilation flow rate; and when the oblique incision 11 adheres to the tracheal wall, the breathing gas can enter and exit through this side hole.

[0037] The oblique incision 11 has a slanted opening, which can provide a better view when the front end advances near the vocal cords and also facilitates passing through the glottis smoothly. It should be noted that the slanted tip of the oblique incision 11 is a soft slanted tip, which can reduce the risk of soft tissue damage during intubation with the smallest increase in flow resistance.

[0038] In this embodiment, the included angle between the oblique incision 11 and the cross-section of the air duct body 1 is 45°.

[0039] In this embodiment, the pulling member 12 is circular ring-shaped, and a cross-shaped member is arranged in the middle of the circular ring of the pulling member 12. One ends of the four sliding strips 8 far away from the inflation balloon 4 are fixedly connected to the ends of the cross-shaped member of the pulling member 12 in a uniformly distributed manner.

[0040] The working principle of a guiding tracheal catheter of the present utility model is as follows:

[0041] During use, insert one end of the air duct body 1 close to the inflation balloon 4 into the patient's throat. When the insertion into the glottis is not smooth, just hold the cross-shaped member of the pulling member 12 and slightly pull the sliding strip 8 through the pulling member 12 for adjustment. The other end of the sliding strip 8 moves slightly left and right and up and down, realizing the left-right or up-down fine adjustment of the front section of the air duct body 1, enabling the front end of the air duct body 1 to be successfully intubated, avoiding repeated intubation caused by taking out the tracheal catheter and reshaping it during the intubation process, improving the success rate of intubation, and reducing the risk of intubation and the injury to the patient's throat.

[0042] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered by the protection scope of the present utility model.
