Description

Technical Field

[0001] This utility model relates to the technical field of tracheal fixation equipment, specifically a fixation device for an openable and closable tracheal tube. Background Technology

[0002] A endotracheal tube fixation device is a medical device designed to stably fix the endotracheal tube inserted into a patient's trachea in a proper position to ensure airway patency and prevent tube displacement or dislodgement.

[0003] Existing Chinese patent document CN221513159U discloses a endotracheal tube fixing device, including an installation tube, a rigid tube fixedly connected to the surface of the installation tube, a flexible tube sleeved on the surface of the rigid tube, a connecting tube sleeved at the other end of the flexible tube, a sealing ring provided inside the connecting tube, a sleeve fixedly installed inside the rigid tube, an insertion tube provided on the surface of the sleeve, and a fixing component sleeved on the surface of the flexible tube. This endotracheal tube fixing device, through the arrangement of the rigid tube, flexible tube, connecting tube, sleeve, and fixing component, allows the insertion tube to be sleeved on the surface of the sleeve during use, with the sleeve inside the rigid tube and flexible tube, and then the user... The adjusting rod rotates via an arc plate, causing the threaded flexible strip to move and reduce the size of the telescopic ring. The telescopic ring then tightens the flexible tube, securing the endotracheal tube and facilitating its use. However, this endotracheal tube securing device still has shortcomings: it secures the endotracheal tube by interlocking the tube, sleeve, rigid tube, and flexible tube with other connecting structures. This layered interlocking method is complex, and the endotracheal tube cannot be manually rotated to adjust its angle. When the patient's head or the instrument's position moves, the connecting tube is prone to bending or twisting. The inability to rotate the tube tip can lead to poor air delivery and affect the treatment effect. Utility Model Content

[0004] The purpose of this invention is to address the problems in the aforementioned endotracheal tube fixing devices, which use interconnected tubes, sleeves, rigid tubes, and flexible tubes, along with other connecting structures, to fix the endotracheal tube. However, this layered approach is structurally complex, and the endotracheal tube cannot be manually rotated to adjust its angle. When the patient's head or the instrument's position moves, the connecting tube is prone to bending or twisting. The inability to rotate the tube tip can also lead to poor air delivery and affect the treatment effect. Therefore, this invention provides an openable and closable endotracheal tube fixing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for an openable and closable endotracheal tube, comprising: a breathing mask, an installation cylinder fixedly connected to the top of the breathing mask, an endotracheal hole extending through the top of the breathing mask, a sealing diaphragm ring fixedly connected to the inner side of the endotracheal hole, a spring washer fixedly connected to the top surface of the breathing mask, an abutment spring fixedly sleeved on the outer side of the spring washer, a smooth support ring fixedly connected to the top of the abutment spring, an endotracheal tube passing through the endotracheal hole, an endotracheal abutment ball and an endotracheal conical block fixedly sleeved sequentially on the outer side of the endotracheal tube, an opening and closing cover one and an opening and closing cover two symmetrically hinged to the top of the installation cylinder, a cover body conical groove opening at one end of the opening and closing cover two, a fixing buckle hinged at one end of the opening and closing cover one, and a fixing groove opening at one end of the top surface of the opening and closing cover two.

[0006] As a further embodiment of this utility model: the mounting cylinder is fixedly connected to the top of the breathing mask, and the tracheal hole is opened through the top of the breathing mask and located inside the mounting cylinder.

[0007] As a further improvement of this utility model: the abutting spring is fixed to the top of the breathing mask and inside the mounting cylinder by a spring washer ring, and the center of the abutting spring and the center of the tracheal hole are kept on the same vertical line.

[0008] As a further embodiment of this utility model: the smooth support ring is fixedly connected to the top of the abutting spring, the smooth support ring supports the abutting air tube and the abutting ball, and the friction at the contact point between the two is small.

[0009] As a further improvement of this utility model: both the first and second opening and closing covers are symmetrically provided with the same specifications of cover conical groove structure on their contact sides, and the cover conical groove is adapted to the specifications of the tracheal conical block.

[0010] As a further improvement of this utility model: two sets of fixing buckle structures are symmetrically hinged at one end of the top surface of the opening and closing cover, and two sets of fixing groove structures are symmetrically opened at one end of the top surface of the second opening and closing cover, and the number, specifications and positions of the fixing buckles and fixing grooves are compatible.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the spring washer ring is fixed to the abutment spring above the trachea hole in the installation cylinder, which drives the smooth support ring to press against the trachea abutment ball. This allows the trachea tube to be sealed to the two sets of opening and closing caps through the spherical design, and it can be flexibly rotated and adjusted within a certain angle. This avoids the trachea tube from bending or twisting and being unable to rotate when the patient's head or the instrument position moves, which would cause poor air delivery and affect the treatment effect.

[0013] 2. The opening and closing of the two opening and closing covers, controlled by the fixing buckle and fixing groove, facilitates quick fixation of the endotracheal tube and its connecting structure by the abutment spring. The conical groove of the cover and the conical block of the endotracheal tube increase the sealing of the connection between the top surface of the opening and closing cover structure and the endotracheal tube. This fixing method facilitates quick replacement and installation of the endotracheal tube and its connecting structure, while the multiple sealing structure ensures the overall sealing of the structure.

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 5 In this embodiment of the present invention, a fixing device for an openable and closable endotracheal tube includes: a breathing mask 1, an installation cylinder 2 fixedly connected to the top of the breathing mask 1, an endotracheal hole 3 extending through the top of the breathing mask 1, a sealing membrane ring 4 fixedly connected to the inner side of the endotracheal hole 3, a spring washer 5 fixedly connected to the top surface of the breathing mask 1, an abutment spring 6 fixedly sleeved on the outer side of the spring washer 5, a smooth support ring 7 fixedly connected to the top of the abutment spring 6, an endotracheal tube 8 passing through the endotracheal hole 3, an endotracheal abutment ball 9 and an endotracheal conical block 13 fixedly sleeved on the outer side of the endotracheal tube 8 in sequence, and an opening and closing cover 10 and an opening and closing cover 2 symmetrically hinged to the top of the installation cylinder 2, an opening and closing cover 2 11 having a cover body conical groove 12 at one end, a fixing buckle 14 hinged at one end of the opening and closing cover 10, and a fixing groove 15 at one end of the top surface of the opening and closing cover 2 11.

[0023] Reference Figures 1 to 4 The mounting cylinder 2 is fixedly connected to the top of the breathing mask 1. The tracheal hole 3 is opened through the top of the breathing mask 1 and is located inside the mounting cylinder 2. The abutment spring 6 is fixed to the top of the breathing mask 1 and inside the mounting cylinder 2 by the spring washer ring 5. The center of the abutment spring 6 and the center of the tracheal hole 3 are on the same vertical line. The smooth support ring 7 is fixedly connected to the top of the abutment spring 6. The smooth support ring 7 supports the abutment ball 9 of the tracheal tube, and the friction at the contact point between the two is small.

[0024] The above scheme is adopted: the spring washer ring 5 is fixed to the abutment spring 6 above the tracheal hole 3 in the mounting cylinder 2, which drives the smooth support ring 7 to press against the tracheal abutment ball 9. The ball design enables the tracheal tube 8 to be sealed to the two sets of opening and closing caps and can be flexibly rotated and adjusted within a certain angle. This avoids the tracheal tube from bending or twisting and being unable to rotate when the patient's head or the instrument position moves, which would cause poor air delivery and affect the treatment effect. The bottom end of the tracheal tube 8 passes through the tracheal hole 3 and is sealed by the sealing membrane ring 4.

[0025] Reference Figure 5 Both the first opening and closing cover 10 and the second opening and closing cover 11 have symmetrically formed conical grooves 12 of the same specification on their contact sides. The conical grooves 12 of the cover are adapted to the specifications of the conical block 13 of the trachea. Two sets of fixing buckles 14 are symmetrically hinged to one end of the top surface of the first opening and closing cover 10. Two sets of fixing grooves 15 are symmetrically formed to one end of the top surface of the second opening and closing cover 11. The number, specifications and positions of the fixing buckles 14 and the fixing grooves 15 are adapted to each other.

[0026] The above scheme is adopted: the opening and closing structure of the first opening and closing cover 10 and the second opening and closing cover 11, which are controlled by the fixing buckle 14 and the fixing groove 15, facilitates the quick fixation of the endotracheal tube 8 and its connecting structure by the abutment spring 6. The conical groove 12 of the cover and the conical block 13 of the endotracheal tube increase the sealing between the top surface of the opening and closing cover structure and the endotracheal tube 8. This fixing method facilitates the quick replacement and installation of the endotracheal tube 8 and its connecting structure. At the same time, the multiple sealing structure ensures the overall sealing of the structure.

[0027] The working principle of this utility model is as follows: In use, the spring washer ring 5 is fixed to the abutment spring 6 above the tracheal hole 3 in the mounting cylinder 2, which drives the smooth support ring 7 to press against the tracheal abutment ball 9. This allows the tracheal tube 8 to be sealed to the two sets of opening and closing covers through the spherical design, and it can be flexibly rotated and adjusted within a certain angle. This avoids the connection tube from bending or twisting when the patient's head or the instrument position moves, which would prevent the equipment from rotating and thus cause poor air delivery, affecting the treatment effect. The bottom end of the tracheal tube 8 passes through the tracheal hole 3 and is sealed by the sealing membrane ring 4. The opening and closing structure of the first opening and closing cover 10 and the second opening and closing cover 11, which are controlled by the fixing buckle 14 and the fixing groove 15, facilitates the quick fixation of the tracheal tube 8 and its connecting structure with the abutment spring 6. The conical groove 12 of the cover and the conical block 13 of the tracheal tube increase the sealing of the connection between the top surface of the opening and closing cover structure and the tracheal tube 8. This fixing method facilitates the quick replacement and installation of the tracheal tube 8 and its connecting structure. At the same time, the multiple sealing structure ensures the overall sealing of the structure.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
