Description

A dental pad with ears for fixing endotracheal tube

technical field

The utility model belongs to the technical field of medical devices, in particular to an ear-shaped tooth pad for fixing a tracheal intubation.

Background technique

Endotracheal intubation through oral vision is an important means to establish an artificial airway for clinical anesthesia, first aid resuscitation, and rescue of critically ill patients, and a good fixation of the endotracheal intubation is the guarantee for maintaining the patency of the airway.

The clinically more commonly used method of fixing the endotracheal tube is to bind and fix the endotracheal tube with adhesive tape through a traditional disposable tooth pad, and then fix it on both cheeks of the patient. However, due to the defects in the design of traditional tooth pads, single-person operation is troublesome, and often requires two people to cooperate to fix them, and the stability is poor. In clinical anesthesia and rescue of critically ill patients, due to the external force of the patient's tongue or mouth, it is fixed on the cheek. The adhesive tape will loosen under the action of sweat, saliva and other secretions, and the change of the tightness of the fixing belt will easily cause the displacement of the endotracheal tube, the loosening of the tooth pad, the damage of the oral mucosa, and the prolapse of the endotracheal tube in severe cases. In addition, if the endotracheal intubation is inserted too deep or too shallow, serious accidents will occur, which will directly affect the continuation of anesthesia surgery or rescue, and mechanical ventilation in critically ill patients, and even directly endanger the lives of patients.

Contents of the invention

In order to solve the above-mentioned problems, the utility model discloses a tooth pad with ears for fixing the tracheal intubation. Through ingenious design, the fixing method of the tooth pad is changed, and the tooth pad and the trachea can be connected without additional tools and materials. The cannula is firmly fixed and easy to operate.

In order to achieve the above object, the utility model provides the following technical solutions:

An ear-shaped dental pad for fixing a tracheal intubation, comprising a dental pad body and a fixing bolt, the dental pad body is provided with an intubation hole running through the length direction of the dental pad body, and the intubation hole is used to accommodate Endotracheal intubation, the left and right sides of the dental pad body are respectively provided with fixed ears, the upper and lower sides are respectively provided with retaining plates, and the dental pad body is also provided with a fixing hole, and an internal thread is provided in the fixed hole , one end of the fixing bolt extends into the fixing hole, and the other end exposes the outer surface of the tooth pad body, and the outer periphery of the fixing bolt is provided with an external thread that matches the internal thread of the fixing hole.

Further, the mouthpiece body is divided into an inlet end and an adjustment end by a gear stopper, and the outer surface of the inlet end is covered with a flexible protective layer.

Further, the flexible protective layer is a silicone flexible protective layer or a rubber flexible protective layer.

Further, an operating head is provided at one end of the fixing bolt exposed from the outer surface of the dental pad body.

Further, the fixing ear is provided with a fixing belt perforation.

Further, the mouthpiece body is in the shape of a cuboid.

Further, the mouthpiece body is cylindrical.

Further, the dental pad body is a silicone dental pad body or a rubber dental pad body.

Beneficial effect:

1. Since the intubation hole is placed in the middle of the tooth pad, and the endotracheal tube passes through the hole, the tongue cannot exert external force on the catheter and the bottom of the tooth pad, so the tooth pad will not be pushed out of the front teeth, and the trachea will not occur The separation of the intubation tube and the tooth pad avoids the phenomenon that the endotracheal tube is bent or broken by the occlusion of the teeth, and at the same time avoids the damage of the patient's oral mucosa and teeth; when the tooth pad is fixed on the mouth, the tooth block is set on the Make sure that the patient does not swallow the entire mouthpiece outside the patient's incisors.

2. No additional tools and materials are required, the dental pad and the endotracheal tube can be firmly fixed as one only by the fixing bolt, and the relative position of the endotracheal tube and the dental pad is easy to adjust, and the operation is simple and easy.

3. It is not necessary to bind the tape on the dental pad cumbersomely or use a fixing belt to tie a knot on the dental pad and then fix it. Just use the two ends of the fixing belt to pass through the perforations of the two fixing ears and tie it behind the head to fix it firmly, simplifying the operate.

Detailed ways

The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

Embodiment one

As shown in Figures 1 and 2, the utility model relates to an eared dental pad for fixing tracheal intubation, including a cuboid dental pad body 1 and a fixing bolt 5, and the dental pad body 1 is provided with a penetrating dental pad body An intubation hole 2 in the length direction, the intubation hole 2 is used for accommodating a tracheal intubation. The intubation hole 2 is placed in the middle of the dental pad body 1, and the endotracheal tube passes through the hole. The tongue cannot exert external force on the catheter and the bottom of the dental pad, and the dental pad will not be pushed out of the front teeth, nor will it Separation of the endotracheal tube and dental pads occurs to avoid bending or rupture of the endotracheal tube by the bite of the teeth.

Two fixing ears 4 are arranged on the left and right sides of the dental pad body 1 respectively, and the fixing ears 4 are used to fix the position of the dental pad. Fixing belt perforation 41 is preferably set on the fixing ear 4, so that it is not necessary to bind adhesive plaster on the tooth pad or fix it after knotting on the tooth pad with the fixing belt, and only need to pass through the perforations of the two fixing ears with the two ends of the fixing belt. Ties to the back of the head for a secure fit. Of course, other fixing components such as protrusions and grooves can also be arranged on the fixing ear 4 for positioning the fixing belt.

Tooth stop plates 3 are respectively arranged on the upper and lower sides of the tooth pad body 1 . When the tooth pad is fixed on the mouth, the tooth retaining plate 3 is arranged outside the patient's front teeth to ensure that the patient will not swallow the whole tooth pad in the mouth. With the tooth stopper 3 as the boundary, we call the end of the dental pad body 1 on the left side of the tooth stopper 3 for entering the oral cavity the inlet end 11, and the end on the right side of the tooth stopper 3 is called the adjustment end 12 , The fixed bolt 5 is set on the adjustment end. The outer surface of the inlet port 11 is preferably covered with a flexible protective layer 7, which can be made of rubber or silicone, which can effectively protect the patient's teeth from damage.
