Description

Technical Field

[0001] The utility model relates to the technical field of intubation fixation, in particular to a tracheal tube fixer. Background Art

[0002] Tracheal intubation is one of the important measures in the anesthesia of surgical patients, respiratory therapy for critically ill patients, and rescue and resuscitation of dying patients. It is the most basic operation skill that not only anesthesiologists but also clinicians of other critical emergency disciplines must master. The method of inserting a special tracheal tube (usually made of rubber or polyethylene plastic) into the trachea through the glottis to establish an artificial airway is called tracheal intubation. In clinical practice, oxygen inhalation, medication and artificial respiration are often performed through the inserted tracheal tube.

[0003] Patients who are under general anesthesia or in coma usually have lost their swallowing and coughing reflexes in the throat and have obstructed airways, so endotracheal intubation should be performed. Its advantages are: it can keep the airway open and reduce dead space; it can maintain adequate oxygen supply; it is conducive to clearing secretions in the trachea and bronchi; it can prevent oral secretions, blood and vomitus from being accidentally inhaled into the trachea; it is easy to assist and control breathing; it provides a way to administer drugs; it is conducive to respiratory management in special body positions and parts of surgery. Disadvantages: it can increase airway resistance; it can interfere with the normal physiological defense function of the airway; it can stimulate the eyes and cause pathological vagal reflexes; it can easily damage the lips, teeth, mouth, nose, throat and tracheal mucosa.

[0004] With the development of medical technology and the improvement of people's living standards, as well as the promotion of predictive intubation in medical care, more and more patients are intubated. For patients with long-term intubation, there is a lack of proper intubation tube fixers. Existing intubation tube fixers can only meet the requirements of short-term intubation patients, such as short-term use of surgical anesthesia patients. For long-term intubation patients in ICU, existing intubation tube fixers cannot meet the requirements of patients. The fixation is unstable and it is easy to fall off when the patient lowers or raises his head. In addition, the existing fixator does not protect the oral cavity properly, which puts pressure on the patient's oral cavity and teeth, resulting in compression of the patient's oral skin, and long-term intubation may even cause skin ulceration. In addition, the existing products in use are fixed to the back of the neck with a lace, which causes local force, thereby causing problems such as facial skin compression. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0037] Embodiment 1: A tracheal tube fixator, such as Figure 1 As shown, the fixator comprises a fixator body 1 for fixing the tracheal tube 9 and a head cover 7 for fixing the fixator body 1 on the cheek around the oral cavity, and the head cover 7 is connected to the fixator body 1 by a connecting belt 8;

[0038] like Figure 2-Figure 6 As shown, the fixator body 1 is an arc-shaped body, the inner surface of the arc-shaped body is provided with a buffer layer 11, and the curvature of the arc-shaped body fits the human face, and the arc-shaped body is also provided with an insertion area window allowing the catheter to pass through, and an inlet 5 is also provided on either side of the arc-shaped body to facilitate the entry and exit of the tracheal catheter 9, and a fixing part for fixing the catheter is provided along the insertion area window on the outer surface; the fixing part includes a shark clamp 2 for clamping the trachea 9 and a movable block 3 connected to the shark clamp 2;

[0039] The inner surface of the arc body is also provided with a detachably connected tooth pad 6, including an upper tooth pad 61 and a lower tooth pad 62, and the tooth pad 6 is clamped with the arc body (a socket is provided on the arc body, and an insert is provided on the outer periphery of the tooth pad 6, and the insert is inserted into the socket to realize the detachable connection of the tooth pad 6), and the tooth pad 6 is a silicone pad.

[0040] The shark clamp 2 includes an opening end 21 and a connecting end 22. The opening end 21 is on the same side as the pipe inlet 5 on the arc body, and the other side is the connecting end 22. The connecting end 22 is connected to the claw of the shark clamp 2 through a compression spring, and the connecting end 22 is connected to the movable block 3 through a connecting rod 23; one end of the connecting rod 23 is fixedly connected to the connecting end 22 of the shark clamp 2, and the other end passes through the movable block 3 and is slidably connected to the movable block 3. By pressing the connecting rod 23 on the movable block 3 and then pressing the connecting end 22 of the shark clamp 2, the opening end 21 is expanded to put the trachea 9 tube into the claw, and then the connecting rod 23 is released to clamp the tube.

[0041] like Figure 3 As shown, the movable block 3 is arranged in the sliding groove of the fixed part and slides with the sliding groove. By moving the movable block 3 left and right in the sliding groove, the position of the trachea 9 in the oral cavity is adjusted to facilitate the doctor to observe the situation in the patient's oral cavity through the intubation area window.

[0042] The arc-shaped body is also provided with ears 4 for connecting the hood 7 on both sides. The ears 4 are flat panels, and the panels are provided with long waist-shaped holes for connecting with the connecting belt 8. The connecting belt 8 passes through the waist-shaped holes and is connected to the hood 7; the outer surface of the connecting belt 8 is a Velcro fixing belt, including a sub-belt and a main belt, and the length of the connecting belt 8 is adjusted by bonding the sub-belt and the main belt; the inner surface is provided with a sponge protective layer for avoiding pressure on the facial skin.

[0043] In a specific application mode of a tracheal tube fixer of the utility model, the first step is to insert the tracheal 9 tube into the patient's airway to the correct position according to the standard intubation procedure. Then, by using the tube inlet 5 of the device, the tracheal 9 tube is introduced into the fixed part of the device, which is achieved by squeezing the connecting rod 23 connected to the shark clamp 2, that is, squeezing the connecting rod 23 to open the shark clamp 2, and then pushing the movable block 3 to clamp the tracheal 9 tube into the shark clamp 2. Once the tracheal 9 tube is fixed in the shark clamp 2, the operator can loosen the connecting rod 23, and the shark clamp 2 will automatically close, so that the tracheal 9 tube is stably fixed inside.

[0044] Next, the patient needs to bite the tooth pad 6 on the device and fit the fixator body 1 to the face. At this time, the arc-shaped body can fit the patient's facial contour and provide another layer of stable support. Then, the head cover 7 is put on the patient's head and the fixator body 1 is fixed by adjusting the length of the connecting belt 8. This configuration can ensure that the tracheal tube 9 is stably and reliably fixed during airway management, and can effectively prevent the risk of the tube slipping out or moving.

[0045] In this fixed state, if the doctor needs to observe the situation in the patient's oral cavity, the position of the tracheal tube 9 can be adjusted by sliding the movable block 3 left and right on the slide. This design allows the doctor to adjust the angle and depth of the tracheal tube 9 as needed, making it more convenient to observe and inspect the oral cavity.

[0046] In general, the tracheal 9 tube fixer provided by the utility model is reasonably designed, easy to operate, safe and reliable, and has significant advantages in terms of stable fixation of the tracheal 9 tube and convenience for doctors to observe the oral cavity.
