Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a tracheal intubation fixing device which is convenient for clinical nursing observation. Background Art

[0002] Endotracheal intubation is a medical procedure that inserts a special endotracheal tube into the patient's trachea through the mouth or nose to establish an artificial airway and ensure ventilation. It is a key technology in emergency, anesthesia and intensive care, and is widely used in scenarios such as respiratory failure, general anesthesia or airway protection.

[0003] Most patients who undergo endotracheal intubation are in a coma and have difficulty controlling their bodies. When medical staff need to check the position and status of the endotracheal tube, or clean the secretions and mucus in the patient's mouth and trachea, multiple people are required to work together, one to open the patient's mouth and stabilize the endotracheal tube, and one to clean it. This undoubtedly wastes human resources and increases the difficulty of medical manpower allocation.

[0004] Existing technologies, such as patent publication number CN219462229U, disclose a tracheal tube fixing device, which fixes the device on the patient's head with a strap, making the patient less comfortable when lying down and more restrained, and uses upper and lower braces to open the patient's upper and lower jaws, so that the tracheal tube can be moved left and right for cleaning. In addition, the existing technology is not suitable for older patients with loose teeth, and uncustomized braces may cause damage to their teeth.

[0005] Therefore, it is necessary to propose a tracheal tube fixation device that does not require additional binding and fixation, can adapt to different patient tooth shapes, maximize patient comfort and safety, and can take into account the tracheal tube fixation and upper and lower jaw opening functions to facilitate clinical nursing observation. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a tracheal tube fixing device which is convenient for clinical nursing observation. By rotating the support nut to push the sliding support ring and the support rod to support the bite groove, the patient's upper and lower jaws can be stretched and fixed to reduce the manpower requirements during nursing. The bite groove can also adapt to the shape of the upper and lower teeth of different patients and solidify, reducing the safety risk of loosening caused by excessive pressure on individual teeth.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a tracheal cannula fixing device convenient for clinical nursing observation, comprising a tracheal cannula, a plurality of card slots are fixedly connected to the outer periphery of the tracheal cannula, a fixing tube is slidably sleeved on the tracheal cannula, a fixing assembly is rotatably connected to one axial end of the fixing tube, the fixing assembly is used to axially fix the fixing tube to the tracheal cannula, a supporting nut and a sliding supporting ring are sleeved on the outer periphery of the fixing tube, the outer periphery of the fixing tube is threadedly matched with the supporting nut, the fixing assembly is located on the movement trajectory of the supporting nut, the end of the supporting nut away from the fixing assembly is rotatably connected to the sliding support ring, the end of the sliding support ring away from the supporting nut is symmetrically hinged with a plurality of supporting rods, a plurality of supporting slide grooves are symmetrically opened on the outer periphery of the fixing tube, support columns are hinged in the supporting slide grooves, the fixing tube is symmetrically sleeved with bite grooves up and down, and the bite grooves are hinged to the corresponding support rods and support columns on the side close to the fixing tube.

[0008] The principle of the basic solution is: by rotating the support nut, the sliding support ring is pushed to move along the axial direction of the fixed tube. The movement of the sliding support ring drives the support rod and the support column to slide in the support slide, thereby pushing the bite groove to expand outward or contract inward. The expansion of the bite groove can open and fix the patient's upper and lower jaws, reducing the manpower requirements during nursing.

[0009] The beneficial effects of the basic solution are as follows: 1. In the traditional endotracheal intubation care process, the nursing staff needs to manually open the patient's mouth and fix the upper and lower jaws and the endotracheal tube, and then other people clean the patient's mouth. The present invention realizes the opening and fixing functions through the linkage design of the support nut, the sliding support ring and the support rod. The nursing staff only needs to rotate the support nut to complete the operation, which greatly reduces the manpower input and improves the nursing efficiency. Especially in the scenario of long-term care or frequent adjustment, the advantages are more obvious.

[0010] 2. On the basis of convenient care, the occlusal groove and fixed tube are located at the closed front teeth of the patient, which can prevent the front teeth and lips from pressing on the tracheal tube, avoiding medical risks caused by reduced gas delivery efficiency of the tracheal tube.

[0011] 3. In the process of rotating the support nut to open the patient's upper and lower jaws, the support nut allows medical staff to slowly and accurately control the degree of expansion to avoid excessive or rapid expansion that may cause damage to the patient's body.

[0012] 4. Compared with the prior art, this technical solution avoids the use of additional binding to connect the device to the patient, and instead uses a bite groove to fix it to the patient's mouth, which not only reduces the restraint on the patient's head and improves the patient's comfort, but also can indicate whether the endotracheal tube is detached.

[0013] Furthermore, the occlusal grooves are all facing outwards and are paved with occlusal membranes, the space between the occlusal membranes and the bottom of the occlusal grooves is filled with solidified fillers, and a number of elastic balls wrapped in liquid are placed in the solidified fillers.

[0014] The beneficial effects of the basic solution are: 1. Through the combination of occlusal membrane and solidified filler, the occlusal groove can fit the upper and lower jaw tooth shapes of different patients more closely, thereby improving the adaptability and stability of the device. This design not only improves the patient's comfort, but also effectively reduces the safety risks caused by loose devices.

[0015] 2. The fixation effect of the occlusal groove can be further enhanced by biting the elastic ball to solidify the solidified filler, ensuring that the device will not fall off or shift due to the patient's activities during use.

[0016] 3. The use of bite membrane can effectively reduce the pressure and damage of the bite groove on the patient's oral tissue and improve the patient's comfort. This is especially important for patients who need to use endotracheal intubation for a long time, which can reduce the anxiety and resistance caused by discomfort.

[0017] 4. Through the combined design of solidified filler and elastic ball, medical staff can complete the installation and adjustment of the device more easily. This design not only improves work efficiency, but also reduces the difficulty and complexity of operation.

[0018] Furthermore, a pipe groove matching with the fixing pipe is provided at the center of one side of the bite groove close to the fixing pipe.

[0019] The beneficial effect of the basic solution is that through the design of the tube groove, the bite groove can be wrapped more closely around the fixed tube, reducing the additional pressure on the patient's oral tissue. This design helps to improve the patient's comfort, especially when the endotracheal tube is used for a long time, which can reduce the patient's discomfort.

[0020] Furthermore, the fixing assembly includes a rotating ring, which is rotatably connected to the fixing tube, and a notched clamping ring is fixedly connected to the inner side of the rotating ring, and the notched clamping ring is slidably matched with the clamping groove.

[0021] The beneficial effects of the basic solution are: 1. The sliding fit design of the notched clamp ring and the clamping groove ensures a tight connection between the fixing component and the endotracheal tube. This sliding fit is not only convenient for installation and adjustment, but also can effectively prevent the endotracheal tube from shifting or falling off during use, thereby greatly enhancing the reliability and stability of fixation. This is of great significance for ensuring the ventilation safety of patients and reducing nursing risks.

[0022] 2. The rotating connection design between the rotating ring and the fixed tube allows the fixed component to be easily rotated on the fixed tube, so that medical staff can adjust the position of the fixed tube on the endotracheal tube according to actual needs. This design not only improves the flexibility of operation, but also simplifies the installation and adjustment process, making the use of the entire fixing device more convenient.

[0023] 3. The sliding fit design makes the connection between the fixed component and the endotracheal tube more flexible, making it easier for medical staff to clean and maintain it when necessary. This design helps maintain the hygiene and performance of the device, reduces the risk of infection, and extends the service life of the device.

[0024] Furthermore, the outer walls of the bite grooves are provided with pipes, the pipes are connected with the outside and the solidified filler, and a rubber plug is fixedly connected inside the pipes.

[0025] The benefits of the basic solution are: 1. Through the design of the pipe and the rubber plug, medical staff can easily inject coagulant materials or melted materials into the solidified filler to adjust its hardness and shape to better fit the patient's tooth shape. This design not only simplifies the filling process of the solidified filler, but also improves the flexibility and accuracy of the adjustment.

[0026] 2. The design of the pipe and plug simplifies the adjustment and maintenance process of the bite groove, allowing medical staff to complete related operations more quickly and accurately. This helps improve nursing efficiency, especially in emergency situations.

[0027] Furthermore, the outer wall of the occlusal groove is engraved with a plurality of longitudinally arranged disengagement scales for indicating the position change of the patient's lips on the outer wall of the occlusal groove.

[0028] The beneficial effects of the basic scheme are: 1. The design of the detached scale enables medical staff and patients to intuitively observe the position change of the lips on the outer wall of the bite groove. This change can reflect the change in the fixation state of the endotracheal tube, which helps to timely discover and deal with possible displacement or fall-off.

[0029] 2. By observing the detachment scale, medical staff can quickly determine whether the endotracheal tube needs to be adjusted or re-fixed, thereby improving the efficiency and accuracy of nursing. This design helps to reduce patient discomfort and nursing risks caused by improper fixation.

[0030] Furthermore, the outer walls of the bite grooves are wrapped with a skin-friendly layer.

[0031] The benefits of the basic solution are: 1. The design of the skin-friendly layer makes the contact between the bite groove and the patient's lips and oral tissues softer, reducing the pain and damage caused by direct contact with hard materials. This design helps to improve the overall comfort of the patient, especially when using endotracheal intubation for a long time.

[0032] 2. The skin-friendly layer not only provides a comfortable contact surface, but also increases the friction between the bite groove and the lips to a certain extent, thereby enhancing the stability of fixation. This design helps prevent the endotracheal tube from accidentally falling off due to patient activity or external force, ensuring the patient's ventilation safety.

[0033] 3. The skin-friendly layer usually has good stain resistance and easy cleaning, which makes it easier for medical staff to clean and maintain the bite slot to maintain its hygiene and performance. This design helps reduce the risk of infection and extend the service life of the device.

[0034] Furthermore, the bite groove and the skin-friendly layer are both made of transparent material.

[0035] The benefits of the basic solution are: 1. The transparent material makes the structure and status of the bite groove and the skin-friendly layer clearly visible. For medical staff, this means that they can visually observe the solidification status of the solidified filler and the patient's bite in the bite groove, so as to make timely adjustments.

[0036] 2. The transparent design allows medical staff to see whether the elastic balls in the solidifying filler are bitten to release liquid to help the solidifying filler solidify, which helps medical staff to fix the bite groove on the patient's upper and lower jaws.

[0037] Furthermore, the liquid in the elastic ball is a colored liquid, which is used to indicate the situation in which the liquid penetrates into the solidified filler after the elastic ball is broken.

[0038] The beneficial effects of the basic scheme are: 1. When the elastic ball is broken due to external force, the colored liquid inside it will quickly penetrate into the solidified filler. This color change provides an intuitive indication for medical staff, allowing them to quickly identify whether the elastic ball has been broken and the scope and degree of liquid leakage, thereby helping medical staff to install the bite groove.

[0039] 2. The use of colored liquid enhances the safety of the device. If the elastic ball breaks accidentally, medical staff can immediately detect it through the color change, avoiding the safety risks caused by improper use of the bite slot.

[0040] Furthermore, one side of the card slot is engraved with an indicator scale located on the endotracheal tube, which is used to indicate the distance between the corresponding card slot and the end of the endotracheal tube.

[0041] The beneficial effects of the basic scheme are: 1. The existence of the indicator scale enables medical staff to accurately control the depth of the endotracheal tube inserted into the patient's body. By reading the scale value, medical staff can ensure that the end of the tube is in the correct position, thereby avoiding too deep or too shallow insertion and reducing the risk of damage to the patient's airway.

[0042] 2. In emergency or complex situations, it is crucial to insert the endotracheal tube quickly and accurately. The design of the indicator scale simplifies this process, allowing medical staff to quickly determine the intubation depth without relying on other tools or methods, improving the accuracy and efficiency of the operation.

[0043] 3. The distance between the slot fixed by the notch clamp and the end of the endotracheal tube can be indicated by the indicator scale, so that the fixed tube can be flexibly fixed on the slot at different positions, so that medical staff can directly install the bite groove and endotracheal tube.

DETAILED DESCRIPTION

[0049] The following is further described in detail through specific implementation methods:

[0050] Example 1

[0051] Basically as attached Figure 1 , Figure 2The figure shows: a tracheal cannula fixing device that is convenient for clinical nursing observation, comprising an tracheal cannula 1, a plurality of card slots 2 are integrally formed on the outer periphery of the tracheal cannula 1, a fixing tube 8 is slidably sleeved on the tracheal cannula 1, and a fixing component is rotatably connected with the ring groove at one axial end of the fixing tube 8, and the fixing component is used to axially clamp the fixing tube 8 with the tracheal cannula 1, a supporting nut 5 and a sliding supporting ring 6 are sleeved on the outer periphery of the fixing tube 8, and the outer periphery of the fixing tube 8 is threadedly matched with the supporting nut 5, and the fixing component is located on the movement trajectory of the supporting nut 5, and the end of the supporting nut 5 away from the fixing component is rotatably connected to the sliding supporting ring 6, and the end of the sliding supporting ring 6 away from the supporting nut 5 is symmetrically hinged with a plurality of supporting rods 7, and a plurality of supporting slide grooves 11 are symmetrically opened on the outer periphery of the fixing tube 8, and support columns 12 are hinged in the supporting slide grooves 11, and the fixing tube 8 is symmetrically sleeved with bite grooves 9 at the upper and lower sides, and the bite grooves 9 are hinged with the corresponding support rods 7 and support columns 12 on the side close to the fixing tube 8. A pipe groove 18 matching with the fixing pipe 8 is formed in the center of the engaging groove 9 close to the fixing pipe 8 .

[0052] The fixing assembly includes a rotating ring 4, which is rotatably connected to the fixing tube 8. A notch clamping ring 15 is fixedly connected to the inner side of the rotating ring 4, and the notch clamping ring 15 is slidably matched with the clamping slot 2. An indicator scale 3 located on the endotracheal tube 1 is engraved on one side of the clamping slot 2 to indicate the distance between the corresponding clamping slot 2 and the end of the endotracheal tube 1.

[0053] The specific implementation process is as follows: the medical staff first selects a suitable card slot 2 according to the required depth of the tracheal tube 1, rotates the rotating ring 4 to turn the notch card ring 15 into the card slot 2 to fix it, so that the fixing assembly and the fixing tube 8 are fixedly sleeved on the surface of the tracheal tube 1, and then the tracheal tube 1 and the fixing tube 8 are inserted into the patient's mouth for intubation, and the bite slot 9 is installed in the patient's upper and lower jaws, and the upper and lower jaws of the patient are closed to fix the bite slot 9. After fixation, the upper and lower jaws of the patient are in a closed state, the tracheal tube 1 passes through the fixing tube 8, and the fixing tube 8 passes through the tube slot 18, so when the patient unconsciously closes his mouth, the tube slot 18 still reserves a ventilation gap for the tracheal tube 1, avoiding the upper and lower jaws from closing and pressing on the tracheal tube 1 to cause poor ventilation, threatening the patient's life safety.

[0054] When the medical staff needs to clean and observe the patient's oral cavity, they first rotate the support nut 5, which makes the support nut 5 move axially on the outer periphery of the fixed tube 8 due to the effect of the thread, thereby pushing the sliding support ring 6 and the support rod 7 to move axially. Since the support column 12 is in an oblique outward direction, when receiving the thrust, the support rod 7 and the support column 12 move together, and both move in a direction away from the surface of the fixed tube 8, thereby lifting the occlusal groove 9 fixed on the upper and lower jaws to make the patient open his mouth. After the medical staff stops rotating the support nut 5, the support nut 5 is fixed in the axial direction and supports the support rod 7 without moving, ensuring the stability of the occlusal groove 9. This frees up the hands of the medical staff to observe and clean the patient's oral cavity.

[0055] like Figure 1 As shown, after the cleaning is completed, the medical staff reverses the support nut 5 and slowly lowers the bite groove 9 to close the patient's mouth to avoid discomfort during long-term endotracheal intubation 1.

[0056] Example 2

[0057] The difference from the above embodiment is that, as shown in the attached Figure 1 , Figure 3 and Figure 4 As shown: the occlusal grooves 9 are all facing outwards and the occlusal grooves 9 are all covered with occlusal membranes 10, the space between the occlusal membranes 10 and the bottom of the occlusal grooves 9 is filled with solidified fillers 16, and a number of elastic balls 17 wrapped with liquid are placed in the solidified fillers 16. The outer walls of the occlusal grooves 9 are all provided with pipes, and the two ends of the pipes are respectively connected to the outside and the solidified fillers 16, and the pipes are bonded with rubber plugs 14. The outer walls of the occlusal grooves 9 are all engraved with a number of longitudinally arranged detachment scales 13, which are used to indicate the position changes of the patient's lips on the outer walls of the occlusal grooves 9. The outer walls of the occlusal grooves 9 are all covered with a skin-friendly layer. The occlusal grooves 9 and the skin-friendly layer are both made of transparent materials. The liquid in the elastic ball 17 is a colored liquid, which is used to indicate the situation where the liquid penetrates into the solidified filler 16 after the elastic ball 17 is broken.

[0058] The specific implementation process is as follows: in the process of installing the bite groove 9, the medical staff first aligns the bite groove 9 with the patient's upper and lower incisors, and then embeds the upper and lower incisors and gums into the bite groove 9. When the patient's upper and lower jaws are closed, the upper and lower teeth are squeezed into the solidified filler 16 through the flexible bite membrane 10. The solidified filler 16 can be a material such as medical plaster that solidifies by controlling the hardness through water. The original state of the medical plaster at this time is powder, which is convenient for the teeth to squeeze into the solidified filler 16. Then the deep teeth squeeze the elastic balls 17 in the solidified filler 16, releasing the colored liquid into the solidified filler 16. The medical staff can see through the transparent bite groove 9 and the skin-friendly layer The penetration of colored liquid can be used to determine whether the solidified filler 16 begins to solidify. After solidification, the solidified filler 16 that has absorbed the colored liquid will squeeze the teeth through the occlusal membrane 10 to increase the friction on the outer wall of the teeth, thereby fixing the occlusal groove 9 and the upper and lower jaws. At the same time, since the shape and number of teeth of each patient are different, the process of biting the unsolidified solidified filler 16 and then fixing it can play a role in shape customization, so that the shape of the solidified filler 16 after solidification conforms to the shape of the upper and lower jaws of each patient, avoiding the pressure of the occlusal groove 9 being concentrated on the upper and lower incisors or longer teeth in the process of stretching the upper and lower jaws of the patient, causing damage to the patient's oral cavity and loosening of the teeth.

[0059] like Figure 3As shown, during the process of removing the endotracheal tube 1, the medical staff can use a syringe to pierce the rubber stopper 14 and inject liquid into the solidified filler 16 again to soften it, thereby facilitating the separation of the bite groove 9 from the patient's upper and lower jaws, making it easier for the medical staff to remove the bite groove 9 and the fixing tube 8, thereby improving the efficiency of medical work and reducing the occurrence of accidents.
