Description

Technical Field

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

[0002] Tracheal intubation is a medical technology that artificially opens the gas passage and uses a tracheal tube to insert into the respiratory tract to maintain gas exchange. It can quickly relieve the patient's respiratory obstruction and provide timely and effective rescue for patients with respiratory dysfunction. At the same time, in the intensive care unit or ward, patients with breathing difficulties also need tracheal intubation to maintain their breathing. When these patients are in critical condition or have a long course of illness, long-term oral tracheal intubation is required to maintain the patient's breathing.

[0003] In the above-mentioned long-term use situation, since the oral endotracheal tube serves as a gas passage, in order to maintain the smoothness of the gas passage and avoid its deformation or blockage, the commonly used endotracheal tube is made of a material with a certain rigidity, such as hard PVC material. At the same time, due to the form of the oral endotracheal tube, the harder tube will generate pressure and friction on the oral mucosa and the skin around the mouth. Long-term contact and friction will cause pressure damage to these areas, increasing the patient's pain. However, if a soft and elastic material is used to make the endotracheal tube, it is easy to deform, resulting in the problem of lumen stenosis and blockage under the action of the airway and the outside. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems in the prior art and provide a tracheal intubation and a tracheal intubation auxiliary device for preventing pressure injuries of the oral mucosa and perioral skin, thereby solving the technical problem of high incidence of oral pressure injuries in the prior art.

[0005] On the one hand, the utility model provides a tracheal intubation for assisting tracheal intubation surgery, comprising:

[0006] The first section is located in the oral cavity and is made of soft material;

[0007] The second section is located in the trachea, one end of the second section facing away from the trachea is fixedly connected to one end of the first section facing toward the trachea, and the second section is made of a hard material;

[0008] The support member is elastic and is arranged in the tubular cavity of the first section, or the support member is buried in the tubular wall of the first section. The support member is used to support the tubular wall of the first section to maintain the tubular shape of the tubular cavity inside the first section.

[0009] Furthermore, the first section is made of soft PVC or soft resin material, and the second section is made of hard PVC or hard resin material.

[0010] Furthermore, the tube wall of the first section has a cylindrical interlayer chamber, which is coaxially arranged with the first section; the support member includes: a spiral support body, which is arranged in the interlayer chamber and coaxially arranged with the first section, and the spiral support body supports the first section to maintain the tubular shape of the internal tube cavity of the first section.

[0011] Furthermore, the spiral support body is made of elastic steel wire.

[0012] Furthermore, the support member includes at least one support ring, which is fixedly connected to the first section and coaxially arranged with the first section. When there are multiple support rings, each support ring is evenly distributed in the first section along the length direction of the first section, and a connecting member is connected between each adjacent support ring, and the support ring and the connecting member are both made of elastic material.

[0013] Furthermore, the endotracheal tube also includes an outer sleeve, the first section and / or the second section is slidably connected to the inside of the outer sleeve, and the outer sleeve is made of a hard material.

[0014] Furthermore, it also includes a limiting structure, which is arranged on the outer surface of the second section toward one end of the first section. The limiting structure can abut against the end of the outer sleeve toward the second section, and the limiting structure is used to limit the sliding of the outer sleeve toward the second section.

[0015] Furthermore, the inner and outer diameters of the first section are smaller than those of the second section, a connecting section is connected between the second section and the first section, the inner diameter of the outer sleeve is larger than the outer diameter of the first section and smaller than the outer diameter of the second section, the connecting section is used to smoothly transition between the inner and outer diameters of the first section and the second section, and the connecting section is made of hard material.

[0016] On the other hand, the present invention also provides a tracheal intubation auxiliary device, which is suitable for any of the above-mentioned tracheal intubations. The tracheal intubation auxiliary device also includes: a fixing mechanism and a clamping member, the fixing mechanism is fixed inside the oral cavity, the clamping member is connected to the fixing mechanism, and the clamping member is clamped at the position where the support member is provided in the first section.

[0017] Compared with the prior art, the beneficial effect of the utility model is that when in use, the end of the second section that is not connected to the first section is directed toward the patient's airway for tracheal intubation, and the second section enters the patient's trachea. Since the second section is made of a hard material, it will not be significantly deformed by the pressure of the airway, and its unobstructedness as an airflow channel is maintained. As the tracheal intubation proceeds, after the tracheal intubation is completed, the tracheal tube left outside the airway, that is, in the oral cavity, is the first section, and the end of the first section connected to the second section should be located on the side of the soft palate facing the outside of the oral cavity. This arrangement ensures that during the long-term intubation process, the soft material is in contact with the oral mucosa, perioral skin and other oral soft components. The first section is made of a material. Due to its soft property, the contact surface of the first section with the oral cavity, lips and other tissues has obvious deformation ability, thereby reducing the deformation degree of these tissues, that is, reducing the pressure on these parts, thereby reducing the risk of pressure trauma. At the same time, it must be taken into account that the easy deformation feature of the first section may lead to the problem of narrowing and blockage of its inner diameter. Therefore, a support is provided in the lumen / wall of the first section. The support can well maintain the tubular shape of the internal lumen of the first section. While the outer wall of the first section is deformed, the deformation of its internal lumen is small, thereby maintaining the smoothness of airflow, thereby solving technical problems and achieving beneficial effects.

[0023] The specific implementation of the utility model is described in detail below, but it should be understood that the protection scope of the utility model is not limited by the specific implementation. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a tracheal intubation. On the one hand, the utility model provides a tracheal intubation for assisting the intubation surgery of the tracheal intubation 1, comprising: a first section 11, a second section 12 and a support member 2, wherein the first section 11 is located in the oral cavity, and the first section 11 is made of a soft material; the second section 12 is located in the trachea, and the end of the second section facing away from the trachea is fixedly connected to the end of the first section facing the trachea, and the second section 12 is made of a hard material; the support member is elastic, the support member 2 is arranged in the first section, and there is a gap between the support member 2 and the inner wall of the first section 11 for gas flow, the support member 2 is used to support the inner wall of the first section 11 to maintain the tubular shape of the internal lumen of the first section 11, or the support member 2 is buried in the wall of the first section 11, and the support member 2 is used to support the wall of the first section 11 to maintain the tubular shape of the internal lumen of the first section 11.

[0025] Specifically, please refer to Figure 1 and Figure 2 When in use, the end of the second section 12 that is not connected to the first section 11 is directed toward the patient's airway for tracheal intubation. The second section 12 enters the patient's trachea. Since the second section 12 is made of a hard material, it will not be significantly deformed by the pressure of the airway, thereby maintaining its unobstructedness as an airflow channel. As the tracheal intubation proceeds, after the tracheal intubation is completed, the tracheal tube left outside the airway, i.e., in the oral cavity, is the first section 11. The end of the first section 11 connected to the second section 12 should be located on the side of the soft palate facing the outside of the oral cavity. This arrangement ensures that during long-term intubation, the first section 11 made of soft material is in contact with soft components of the oral cavity, such as the oral mucosa and perioral skin. 11. Due to its soft nature, the first section 11 has an obvious deformation ability in its contact surface with the oral cavity, lips and other tissues, thereby reducing the deformation degree of these tissues, that is, reducing the pressure on these parts, thereby reducing the risk of pressure trauma. At the same time, it must be taken into account that the deformable feature of the first section 11 may lead to the problem of narrowing and blockage of its inner diameter. Therefore, a support member 2 is arranged in the lumen / wall of the first section. The support member 2 can well maintain the tubular shape of the internal lumen of the first section 11. When the outer wall of the first section 11 is deformed, the deformation of its internal lumen is small, thereby maintaining the smoothness of airflow, thereby solving the technical problem and achieving beneficial effects.

[0026] Furthermore, the first section 11 is made of soft PVC or soft resin material, and the second section 12 is made of hard PVC or hard resin material.

[0027] Provides a first embodiment, please refer to Figure 1The first section 11 has a cylindrical interlayer chamber in its tube wall, and the interlayer chamber is coaxially arranged with the first section 11; the support member 2 includes a spiral support body, which is arranged in the interlayer chamber and coaxially arranged with the first section 11, and the spiral support body supports the first section 11 to maintain the tubular shape of the internal tube cavity of the first section 11. In other embodiments, the spiral support body is arranged in the tube wall of the first section 11 in an embedded manner.

[0028] Based on this embodiment, further, the spiral support body is made of elastic steel wire.

[0029] In this embodiment, the function of the support member 2 is achieved by setting the spiral support body in the tube wall of the first section 11. The setting of this embodiment can well and stably set the spiral support body, and can accompany the movement, bending and deformation of the first section 11 without falling off and dislocation. The spiral support body is made of elastic steel wire and can adapt well to the bending and deformation of the first section 11, so that it can maintain the tubular shape of the internal lumen of the first section 11. Under the premise of not causing blockage of the lumen, the first section 11 has a certain degree of bending ability and deformation, thereby improving its flexibility and reducing the pressure of the first section 11 on the perioral soft tissue.

[0030] A second embodiment is provided, please refer to Figure 2 The support member 2 includes at least one support ring, which is fixedly connected to the first section 11 and coaxially arranged with the first section 11. The outer side of the support ring contacts the inner side wall of the first section 11. When there are multiple support rings, each support ring is evenly distributed in the first section along the length direction of the first section, and a connecting member is connected between adjacent support rings, and the support ring and the connecting member are both made of elastic material.

[0031] In this embodiment, a plurality of support rings are evenly distributed in the first section along the length direction of the first section, and can support and maintain the tubular shape of the internal lumen of the first section 11 when the first section 11 is in a straight line. However, due to the gaps between the plurality of support rings, when the first section 11 is bent at a large angle or the gaps between adjacent support rings are large, the bent / curved first section 11 will produce obvious deformation and accumulation of deformed tube walls between adjacent support rings, so there is still a risk of blockage and stenosis of the lumen. Therefore, a connector is also provided between the support rings to support the tube wall of the first section 11 between the support rings, thereby avoiding the above risks. Since the support rings and the connectors are both made of elastic material, the first section 11 has a certain degree of bending ability and deformation, which improves its flexibility and reduces the pressure of the first section 11 on the perioral soft tissue. In this embodiment, the support rings and the connectors do not need to be buried inside the tube wall of the first section 11, but are arranged in the tube cavity of the first section 11. Compared with the method of burying them in the tube wall, the production cost is lower and the processing difficulty is lower.

[0032] Furthermore, the first section 11 is configured to maintain the shape of the lumen and reduce the pressure on the tissue. However, in the embodiments of these configurations, the soft first section 11 and the elastic support 2 have deformation capabilities that affect the gripping and exerting force during the operation, which are not conducive to the intubation during the intubation. Considering the operational issues during actual use, the first section 11 cannot be configured as a harder structural component. Therefore, in particular, the tracheal tube 1 also includes an outer tube 3, the first section 11 and / or the second section 12 are slidably connected to the inner part of the outer tube 3, and the outer tube 3 is made of a hard material.

[0033] In this embodiment, the hard outer sleeve 3 can be slidably mounted on the first section 11 and / or the second section 12, thereby providing a holding and operating position. A person holds the outer sleeve 3 with the first section 11 and / or the second section 12 to perform intubation. After the intubation is completed, the outer sleeve 3 is slid so that it can be removed.

[0034] Furthermore, in order to further enhance the auxiliary operation function of the outer sleeve 3, it is necessary to provide the outer sleeve 3 with a component capable of transmitting force, and thus a limiting structure is also included, which is provided on the outer surface of the second section 12 facing the end of the first section 11, and the limiting structure can abut against the end of the outer sleeve 3 facing the second section 12, and the limiting structure is used to limit the sliding of the outer sleeve 3 toward the second section. This facilitates the positioning and force transmission of the outer sleeve 3, and enhances the auxiliary operation function of the outer sleeve 3.

[0035] Furthermore, in order to avoid providing a clearly protruding limiting structure on the first section 11 and the second section 12, so as to avoid the generation of hooking points and the risk of trauma to the oral cavity and the airway, a special embodiment is provided, please refer to Figure 1 , the inner and outer diameters of the first section 11 are smaller than the second section 12, a connecting section 13 is connected between the second section 12 and the first section 11, the inner diameter of the outer sleeve 3 is larger than the outer diameter of the first section 11 and smaller than the outer diameter of the second section 12, the connecting section 13 is used to smoothly transition between the inner and outer diameters of the first section 11 and the second section 12, and the connecting section 13 is made of hard material. In this embodiment, in the direction from the first section 11 to the second section 12, the outer diameter of the connecting end 13 gradually increases to be larger than the inner diameter of the outer sleeve 3. When the outer sleeve 3 moves to this position, its inner diameter cannot accommodate the connecting section 13 or / and the second section 12 with a larger outer diameter, so that a limiting effect will be applied, which limits the sliding of the outer sleeve 3 toward the second section. In this embodiment, the second section 12 and the connecting section 13 are regarded as an implementation of a limiting structure. In this implementation, the smooth transition of the connecting section 13 solves the defect of the conventional limiting structure generating a hooking point.

Any of the above-mentioned endotracheal intubations can be well adapted to this endotracheal intubation auxiliary device, which is applicable to patients who use intubation for a long time, and reduces the risk of pressure trauma.
