Abstract
Description
Technical Field
[0001] The invention relates to the technical field of endotracheal intubation, in particular to an anti-infection protection device for medical endotracheal intubation. Background Art
[0002] In the past, a variety of intubation tools or equipment were used for tracheal intubation or respiratory examination in the operating room, emergency department, ward, and ICU. Commonly used ones include direct laryngoscope, intubation stylet, bougie, light stick, visual laryngoscope, visual rigid intubation light stick, and visual intubation soft mirror. In order to avoid cross-infection problems caused by various intubation tools during the intubation process, various disinfection measures or protective covers are often used in clinical practice to protect various tools and medical procedures. In the modern medical field, tracheal intubation is an important operation and is widely used in anesthesia, first aid, and the treatment of patients with respiratory dysfunction. Tracheal intubation can establish an effective artificial airway and ensure the patient's oxygen supply and gas exchange, which is of key significance for saving patients' lives and improving treatment outcomes.
[0003] There are many problems and challenges in the process of tracheal intubation and subsequent use. First, during the intubation operation, it is necessary to ensure that the tracheal tube is accurately inserted into the trachea to an appropriate depth, which requires high operating skills of medical staff, and the tracheal tube needs to be properly fixed after insertion to prevent it from shifting or falling out. For example, the anti-infection protection device for tracheal intubation with announcement number CN112076373A is arranged on the outlet pipe of the tracheal tube, and the body of the bronchoscope passes through the tracheal tube. The device includes a hollow sleeve and a closed airbag, one end of the sleeve is provided with a rubber plug, and the other end is sealed with the outlet pipe. A through hole is formed on the rubber plug, and the diameter of the through hole is smaller than the outer diameter of the body of the bronchoscope. An opening is formed on the side wall of the sleeve, and one end of the airbag is sealed and connected with the opening on the side wall of the sleeve. The airbag is also provided with a drainage port for removing internal dirt. The droplets generated in the patient's trachea will enter the cannula through the gap between the mirror body and the endotracheal tube, then enter the air bag for collection from the opening on the side wall of the cannula, and finally gather into the drainage bottle from the drainage port, thus solving the technical problem of droplets spraying from the tracheal outlet tube and polluting the surrounding environment, which helps to protect patients and medical staff.
[0004] The traditional fixation method uses ventilation gauze to tie on the head, which may not be stable enough during the tying process and is easily affected by factors such as the patient's head movement and oral secretions, resulting in changes in the position of the endotracheal tube, thereby affecting the ventilation effect. Furthermore, the patient cannot control the closure of the mouth independently during the endotracheal intubation and is prone to biting the tube, which may not only damage the endotracheal tube and affect the ventilation function, but also cause oral tissue injury. At the same time, secretions and bacteria in the patient's mouth are easy to accumulate around the endotracheal tube, increasing the risk of respiratory infection, especially in the case of long-term intubation, the risk of infection is higher, which is extremely unfavorable for the patient's recovery. In this regard, an anti-infection protection device for medical endotracheal intubation is proposed. Summary of the invention

The top of the connecting piece 8 is rotatably connected with a rotating handle 9. The outer wall of the rotating handle 9 is provided with an anti-slip thread. The bottom of the rotating handle 9 is fixedly connected to the anti-bite piece 6. The connecting piece 8 is sleeved on the outer wall of the endotracheal tube and is installed with the bottom of the silicone sleeve 5 in the form of a threaded connection. In addition, the outer wall of the anti-bite piece 6 is provided with a protective layer 10, which can increase the friction and further stabilize its position.

[0040] As another aspect of the present invention, the above-mentioned method for protecting the medical endotracheal tube infection protection device comprises the following steps:
[0041] Step 1: Check the integrity of the anti-infection protection device for medical endotracheal intubation, select the device of appropriate size according to the patient's condition, and ensure that it can fit tightly with the patient's airway and oral area without causing excessive pressure;
[0042] Step 2: Put the bottom of the anti-bite piece 6 into the patient's mouth and then turn the rotating handle 9 to make the anti-bite piece 6 enter the appropriate position of the patient's mouth. After the patient's mouth is opened, the endotracheal tube 1 is prevented from biting the patient. The endotracheal tube 1 is inserted into the trachea through the patient's mouth to a predetermined depth. During the operation, the action should be gentle to avoid damaging the airway tissue. During this period, the silicone sleeve 5 moves upward to fit the outer wall of the endotracheal tube 1. At this time, the fixing belt 4 is in an operable state.
[0043] Step 3: Take out the end clamp 15 of the fixing belt 4 from the fixing slot 13, and then pass the splicing piece 19 through the splicing holes 11 on the front and rear sides of the clamp 15 to connect and fix the two fixing belts 4 to ensure that the endotracheal tube 1 is stable on the patient's head and will not shift. During this period, adjust the tightness of the fixing belt 4 to fix the position of the endotracheal tube 1 without affecting the patient's blood circulation;
[0044] Step 4, inflate the airbag 16 through the inflation tube 3, and observe the filling condition of the airbag 16 during the inflation process. When the airbag 16 is moderately inflated, can effectively seal the airway and the patient has no obvious discomfort, stop inflating. After the airbag 16 is inflated, the position of the endotracheal tube 1 can be further fixed and oral secretions can be prevented from entering the airway. According to the patient's treatment needs, drugs can be injected into the endotracheal tube 1 through the drug delivery tube 2. During the whole process, medical staff can observe the internal situation of the oral cavity through the observation groove 7 on the silicone sleeve 5, and continuously monitor the patient's vital signs and the position and patency of the endotracheal tube 1. The pressure of the airbag 16 is checked regularly. If the pressure is insufficient, gas is added in time to ensure that the airway is well sealed.
