Abstract
Description
Technical Field
[0001] This invention relates to the field of medical surgical instruments, specifically to an endotracheal intubation guide. Background Technology
[0002] Traditional endotracheal intubation guides use rigid medical tubing, which is inserted into the patient's larynx and then guided in. The main drawback of this method is that it can only extend the insertion and cannot support the wall of the larynx. When encountering larynx lesions or narrowing of the larynx due to the patient's physiological defects, endotracheal intubation becomes difficult. Therefore, we propose an intubation guide that can expand the patient's trachea to facilitate tracheal access. Summary of the Invention
[0003] In view of the deficiencies in the prior art, the present invention provides an endotracheal intubation guide to achieve dilation and facilitate endotracheal insertion.
[0004] The present invention provides an endotracheal intubation guide, comprising: a guide, the guide including a guide main tube, an inlet tube sleeve, and a connecting tube section; the inlet tube sleeve is disposed at one end of the guide main tube; the connecting tube section is disposed outside the tube wall of the guide main tube, and one end is connected to the inlet tube sleeve; the connecting tube section is further provided with an external pressure tube, the external pressure tube being disposed at the side wall of the connecting tube section; and a dilator tube, the dilator tube being disposed on the outer tube wall of the guide main tube, and one end being connected to the connecting tube section.
[0005] Furthermore, the guide also includes a connecting tube, one end of which is connected to the external pressure tube, and the other end of which is connected to an external pressure source. In practical applications, the purpose of this design is to facilitate pressurization. In actual work, a large-sized syringe is used as the external pressure source, thus enabling the delivery of the pressure medium into the external pressure tube, thereby expanding the dilator. In fact, the pressure medium is a liquid, often medical saline solution, which allows for both pressurization and convenient sterilization.
[0006] Furthermore, the expansion tube includes a pressure-deformation sleeve, which is installed on the outer wall of the guide tube and communicates with the connecting pipe section. In practical applications, the purpose of this design is to achieve a deformation and expansion effect after pressurization, thereby facilitating the expansion effect and effectively opening the air hole. This makes it easier to insert the air guide tube and further facilitates guidance.
[0007] Furthermore, the pressurized deformable sleeve is equipped with thin-walled sections and a permeable membrane. Multiple thin-walled sections are spaced apart and located at the pressurized deformable sleeve. The permeable membrane is disposed on the thin-walled sections. In practical applications, the purpose of this design is to achieve multiple points of contact, thereby reducing pressure concentration in a single area and achieving multi-area pressure distribution. This allows for even expansion of the patient's trachea. Simultaneously, the permeable membrane used is a synthetic polymer membrane, which effectively allows physiological saline to seep out, thus achieving active disinfection. Furthermore, the expansion tube also includes an inner expansion member, one end of which is mounted on the guide tube and located inside the pressure-deformation sleeve, and connected to the inner wall of the pressure-deformation sleeve. In practical applications, the purpose of this design is to effectively support the aforementioned pressure-deformation sleeve, facilitating internal wall support and allowing the sleeve to expand outwards; because when it expands inwards, it is limited by the inner expansion member.
[0008] Furthermore, the inner extension component includes a fixed end and a supporting hinge rod. The fixed end has multiple hinge seat holes, and multiple supporting hinge rods are provided, each installed at one of the hinge seat holes. One end of each supporting hinge rod is hinged to a hinge seat hole; the other end of each supporting hinge rod is connected to the pressure deformation sleeve. In practical applications, the purpose of this design is to achieve limit adjustment. Its design is similar to that of an umbrella, enabling unidirectional end expansion, thus facilitating unidirectional enlargement and making air tube insertion more convenient.
[0009] Furthermore, the inner expansion member also includes an inner ring sleeve, which is located at the supporting hinge rod of the inner expansion member, and the outer wall of the inner ring sleeve is connected to the outer walls of the multiple supporting hinge rods. In practical applications, the purpose of this design is to control the supporting hinge rods and facilitate the expansion of one end. It adopts a pressure deformation design concept, which enables unidirectional expansion of the multiple supporting hinge rods. In the actual design, a fixed inner sleeve is also installed on the inner wall of the inner ring sleeve. One end of the fixed inner sleeve is connected to a fixed end, and the other end of the fixed inner sleeve extends outward and abuts against the inner ring sleeve. This limits the inner ring sleeve and prevents it from expanding inward, effectively ensuring its outward expansion.
[0010] Furthermore, the inner expansion component also includes a connecting secondary tube, and the inner ring sleeve is also provided with a communicating port. One end of the connecting secondary tube passes through the feed tube sleeve and extends into the guide tube, communicating with the communicating port; the other end of the connecting secondary tube is connected to an external pressure source. In practical applications, the purpose of this design is to facilitate the control of the inner ring sleeve, communicating with the external pressure source through its connecting secondary tube. In actual work, a conventional syringe can be used as the external pressure source. In actual operation, the syringe has a graduation mark, which can effectively and conveniently determine the amount of liquid to be injected. In this way, the expansion range of the inner ring sleeve can be effectively limited, thereby limiting the range of motion of the multiple supporting hinge rods mentioned above, thus avoiding excessive dilation of the patient's trachea.
[0011] As can be seen from the above technical solution, the beneficial effects of the endotracheal intubation guide provided by the present invention are as follows: In practical applications, the guide device used in this design combines guided insertion with tracheal dilation at the insertion site; this not only facilitates guidance during tracheal insertion but also allows for easy introduction of the trachea through tracheal dilation. In this design, the guide tube, feed tube sleeve, and connecting pipe section are designed to facilitate the insertion of the air tube, which is inserted into the guide tube through the feed tube sleeve. On the other hand, the connecting pipe section is equipped with an external pressure pipe, which enables the external pressure source to communicate with the expansion tube, thereby achieving effective expansion of the expansion tube.

Detailed Implementation
[0014] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0015] The basic implementation examples are as follows: Figures 1 to 5 As shown: like Figure 1 - Figure 5 As shown in the figure, this embodiment provides an endotracheal intubation guide that can be expanded to facilitate endotracheal insertion.
[0016] The present invention provides an endotracheal intubation guide, comprising: a guide 1, the guide 1 including a guide main tube 11, an inlet tube sleeve 12 and a connecting tube section 13; the inlet tube sleeve 12 is disposed at one end of the guide main tube 11; the connecting tube section 13 is disposed outside the tube wall of the guide main tube 11, and one end is connected to the inlet tube sleeve 12; the connecting tube section 13 is further provided with an external pressure tube 131, the external pressure tube 131 being disposed at the side wall of the connecting tube section 13; and an expansion tube 2, the expansion tube 2 being disposed on the outer tube wall of the guide main tube 11, and one end being connected to the connecting tube section 13. In practical applications, the guide device 1 used in this design combines guided insertion with tracheal dilation at the insertion site. This not only facilitates tracheal guidance during insertion but also allows for easy introduction of the trachea through tracheal dilation. The guide device 1 in this design employs a guide tube 11, an inlet tube sleeve 12, and a connecting tube section 13. The guide tube 11 and inlet tube sleeve 12 facilitate tracheal insertion, allowing the trachea to be inserted into the guide tube 11 via the inlet tube sleeve 12. Furthermore, the connecting tube section is equipped with an external pressure tube 131, enabling communication between an external pressure source and the dilator tube 2, thereby achieving effective expansion of the dilator tube 2.
[0017] For ease of connection, in this embodiment, the guide 1 further includes a connecting tube 14, one end of which is connected to the external pressure tube 131, and the other end of which is connected to an external pressure source. In practical applications, the purpose of this design is to facilitate pressurization. In actual work, a large syringe is used as the external pressure source, thus enabling the delivery of the pressure medium into the external pressure tube 131, thereby expanding the dilator 2. In fact, the pressure medium is a liquid, often medical saline solution, which allows for both pressurization and convenient disinfection.
[0018] To achieve deformation, in this embodiment, the expansion tube 2 includes a pressure-deformation sleeve 21, which is installed on the outer wall of the guide tube 11 and communicates with the connecting tube section 13. In practical applications, the purpose of this design is to achieve a deformation and expansion effect after pressurization. This facilitates the expansion of the pores, effectively opening the air holes, thus making it easier to insert the air guide tube and further facilitating guidance.
[0019] Meanwhile, to achieve lubrication and reduce surface damage from friction, in this embodiment, the pressure-adjustable sleeve 21 is provided with a thin-walled section 211 and a permeable membrane 212. The thin-walled section 211 has multiple locations spaced apart and is situated on the pressure-adjustable sleeve 21. The permeable membrane 212 is disposed on the thin-walled section 211. In practical application, the purpose of this design is to achieve multiple points of contact, thereby reducing pressure concentration in a single area and achieving multi-area pressure bearing. This allows for uniform expansion of the patient's trachea. Simultaneously, the permeable membrane 212 is a synthetic polymer membrane, which effectively allows physiological saline to seep outwards, thus achieving active disinfection.
[0020] Furthermore, in practice, to further facilitate the guidance of the trachea in and out, in this embodiment, the expansion tube 2 also includes an inner expansion member 22. One end of the inner expansion member 22 is installed on the main guide tube 11 and located inside the pressure deformation sleeve 21, and is connected to the inner wall of the pressure deformation sleeve 21. In practical applications, the purpose of this design is to effectively support the pressure deformation sleeve 21, effectively and conveniently provide inner wall support for the pressure deformation sleeve 21, and facilitate the outward expansion of the pressure deformation sleeve 21; because when it expands inward, it can be limited by the inner expansion member 22.
[0021] Furthermore, to achieve unidirectional expansion, in this embodiment, the inner extension member 22 includes a fixed end 221 and a supporting hinge rod 222. The fixed end 221 has multiple hinge seat holes 2211, and the supporting hinge rod 222 has multiple locations, each installed at one of the hinge seat holes 2211. One end of the supporting hinge rod 222 is hinged to the hinge seat hole 2211, and the other end of the supporting hinge rod 222 is connected to the pressure deformation sleeve 21. In practical applications, the purpose of this design is to achieve limit adjustment. Its design is similar to that of an umbrella, enabling unidirectional end expansion, thus facilitating unidirectional enlargement and making it easier to insert the air tube.
[0022] In this embodiment, the inner expansion member 22 further includes an inner ring sleeve 223, which is disposed at the support hinge rod 222 of the inner expansion member 22, and the outer wall of the inner ring sleeve 223 is connected to the outer walls of the multiple support hinge rods 222. In practical applications, the purpose of this design is to control the support hinge rod 222 and facilitate the expansion of one end. It adopts a pressure deformation design concept, which enables unidirectional expansion of the multiple support hinge rods 222. In the actual design, a fixed inner sleeve is also installed on the inner wall of the inner ring sleeve 223. One end of the fixed inner sleeve is connected to the fixed end 221, and the other end of the fixed inner sleeve extends outward and abuts against the inner ring sleeve 223. In this way, the inner ring sleeve 223 can be limited to prevent it from expanding inward and effectively ensure its outward expansion.
[0023] To facilitate connection and control, in this embodiment, the inner expansion member 22 further includes a connecting secondary tube 224, and the inner ring sleeve 223 is also provided with a communicating port 2231. One end of the connecting secondary tube 224 passes through the feed tube sleeve 12 and extends into the guide tube 11, communicating with the communicating port 2231; the other end of the connecting secondary tube 224 is connected to an external pressure source. In practical application, the purpose of this design is to facilitate the control of the inner ring sleeve 223, which is connected to the external pressure source through its connecting secondary tube 224. In actual operation, a conventional syringe can be used as the external pressure source. In actual operation, the syringe has a graduation mark, which can effectively and conveniently determine the amount of liquid to be injected. In this way, the expansion range of the inner ring sleeve 223 can be effectively limited, thereby limiting the range of motion of the multiple supporting hinge rods 222, thus avoiding excessive dilation of the patient's trachea.
[0024] In summary, this endotracheal intubation guide is not only reasonably designed but also simple to operate. It can guide external endotracheal insertion while facilitating the patient's entry and exit by dilating the patient's trachea. Therefore, this device is suitable for industry promotion.
