Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing instruments, in particular to a tracheal intubation fixing device for prone ventilation of patients. Background Art

[0002] An artificial airway is a gas passage established by inserting a catheter through the oral cavity into the trachea or performing a tracheotomy. The establishment of this passage facilitates the removal of respiratory secretions from patients and ensures pulmonary ventilation and gas exchange. Through the trachea, oxygen required for people's breathing can be delivered. For some critically ill patients with acute respiratory distress syndrome, prone ventilation is required. Since the prone position requires the patient's body to lie on the nursing bed with the head facing downwards, making the head in a suspended state, tracheal intubation is performed. However, there are still the following problems in clinical practice.

[0003] Clinically, commonly used tracheal intubation usually uses tape to fix the tracheal intubation in the patient's oral cavity. This method is simple and easy to operate. However, the disadvantages include poor fixation and easy detachment, especially for patients with a lot of oral secretions. Once fixed, it cannot be adjusted according to the head position, and the tracheal intubation is prone to bend inside or outside the oral cavity. In a tracheal intubation fixator for prone ventilation of critically ill patients with the patent number CN220558381U, although it can adjust the angle and orientation, due to its independent placement, the stability effect is poor. And it is independent of the nursing bed. If the patient's head deviates, a good fixation and cooperation effect cannot be achieved. Summary of the Utility Model

[0004] The utility model provides a tracheal intubation fixing device for prone ventilation of patients to solve the above technical problems.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A tracheal intubation fixing device for prone ventilation of patients includes a fixing mechanism for a nursing bed. The fixing mechanism includes a fixing frame, a head support pad, a guide plate, an adjustment plate, and a catheter fixing cylinder. The fixing frame is fixedly installed at the head end of the nursing bed through a first bolt. The fixing frame is symmetrically provided with extension plates extending laterally outwards. The head support pad is connected to the fixing frame and is arranged between the two extension plates. The guide plate includes two, and the two guide plates are symmetrically installed at the bottom of the extension plates. The guide plate is provided with a vertical sliding groove. The adjustment plate is fixed between the two guide plates through a second bolt horizontally penetrating the sliding groove. An adjustment hole is opened in the center of the adjustment plate. The catheter fixing cylinder is rotatably arranged on the adjustment hole through a third bolt.

[0007] Furthermore, both the plane and cross-section of the fixing frame are U-shaped structures, and the fixing frame is horizontally inserted into the bed board of the nursing bed. The fixing frame is U-shaped in the plane, which does not affect the patient lying on the nursing bed when installed. The fixing frame is U-shaped in the cross-section, and the fixing frame can be snapped onto the nursing bed along the U-shaped notch to achieve limited placement.

[0008] Furthermore, first threaded holes are symmetrically arranged at the bottom of the fixing frame. The first threaded holes are threadedly connected to first bolts, and a tightening piece is arranged at the free end of the first bolt. After the placement of the fixing frame is completed, the first bolts are tightened from bottom to top. A tightening piece is arranged at the free end of the first bolt, which can increase the stability of fastening.

[0009] Furthermore, second threaded holes are arranged at both ends of the adjusting plate. The second bolts are threadedly connected to the second threaded holes to fix the inclination angle of the adjusting plate. The guiding plate is fixedly arranged below the fixing frame. The adjusting plate can be adjusted up and down. When the required height is reached, the second bolts are tightened at both ends to achieve the height tightening and fixing of the adjusting plate. And according to actual requirements, the inclination of the adjusting plate can be adjusted to realize the adjustment of the height and inclination angle of the adjusting plate.

[0010] Furthermore, one side of the catheter fixing cylinder is rotatably connected to the adjusting plate through a rotating shaft. A third threaded hole that horizontally penetrates the adjusting hole and the outer wall of the adjusting plate is arranged on the adjusting plate. The third threaded hole and the rotating shaft are oppositely arranged with respect to the catheter fixing cylinder. Under the action of the rotating shaft, the catheter fixing cylinder can be tilted. This angle inclination adjustment is a left-right tilt adjustment, while the adjusting plate is a front-back tilt adjustment. After the left-right tilt adjustment of the catheter fixing cylinder is completed, the catheter fixing cylinder is fixed through the cooperation of the third bolt and the third threaded hole.

[0011] Furthermore, the inner cavity of the catheter fixing cylinder is directly larger than the diameter of the tracheal intubation. A locking component for fixing the tracheal intubation is arranged on the catheter fixing cylinder. When the patient lies prone on the nursing bed, the tracheal intubation is passed through the inner cavity of the catheter fixing cylinder and connected to the patient's oral cavity, and the tracheal intubation is fixed through the locking component.

[0012] Furthermore, a bite block for supporting the patient's oral cavity is arranged at the top of the catheter fixing cylinder. The bite block is made of silica gel. When in use, it can not only play an opening support role for the patient's oral cavity, but also play an anti-slip effect, further reducing the risk of the pipeline coming out.

[0013] Furthermore, a groove for accommodating the face is provided on the head support pad, and a head strap is also provided on the top surface of the head support pad. When the patient lies prone on the nursing bed, the adjustment of the adjustment plate and the catheter fixing cylinder can achieve personalized adjustment. After the adjustment is completed, if the patient's head shifts or rotates, it will cause the angle and position of the tracheal intubation to shift, affecting the catheter effect or causing discomfort to the patient. Therefore, through the stretchable and adjustable head strap, the patient's head can be fixed to avoid the situation of tracheal intubation deviation or bending.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The fixing mechanism can be installed on the nursing bed through the fixing frame of the utility model, playing an adaptive fixing role, and making the fixing mechanism and the nursing bed form an integral whole, improving the stability during fixing;

[0016] 2. The adjustment plate and the catheter fixing cylinder of the utility model can be rotated and adjusted according to the patient's condition to adapt to the intubation fixation in various orientations and angles;

[0017] 3. The utility model is convenient for adjustment and operation, and has a stable fixing effect, reducing the workload of medical staff, avoiding the bending of the tracheal intubation at the same time, improving the safety of nursing and reducing the discomfort of the patient.
