Description

Universal dental pad for oral intubation

technical field

The utility model relates to a dental pad, in particular to a universal dental pad for oral intubation.

Background technique

Endotracheal intubation is a common technique for clinical anesthesia and rescue of critically ill patients, and the fixation of the endotracheal tube is the guarantee for the success of the operation. At present, tooth pads are often used to fix the endotracheal tube, which can effectively prevent the tube from being deformed and displaced by the occlusal teeth. The commonly used dental pad structure includes three parts: the dental pad main body, the dental pad wing, and the dental pad card. The dental pad wings are arranged on both sides of the dental pad main body. Teeth bite the endotracheal tube, and the wing of the dental pad is placed on the outer edge of the upper and lower dentition to prevent the displacement of the dental pad. The dental pad is used to fix the endotracheal tube and prevent the displacement of the endotracheal tube. Although this kind of tooth pad with a common structure has the advantages of cheap price, easy operation, and improved surgical efficiency, it also has disadvantages: it is mostly made of high hardness and inelastic material, which has poor compliance with oral soft tissues and is easy to directly damage the tongue. , oral mucosa, gums and other tooth soft tissues, etc.; and the comfort is not high during use, and it is easy to shift. Patients with long-term mechanical ventilation and recovery period may also cause teeth loosening or falling off due to mechanical contact, which will bring unnecessary inconvenience to the patient. The iatrogenic injury may even lead to conflicts between doctors and patients.

Utility model content

The purpose of this utility model is to overcome the shortcomings in the prior art and provide a universal dental pad for oral intubation, which has the advantages of being comfortable for patients to use, avoiding damage to the tongue, oral mucosa and soft tissue of the teeth, and can also protect teeth to the greatest extent. Teeth, especially those with misaligned dentition and partial loss of incisors.

In order to achieve the above object, the utility model adopts the following technical solutions: it includes a dental pad main body, and one side of the dental pad main body is provided with an alveolar; A fixed arm extending outward is provided at the place;

The main body of the dental pad is in an arc shape that can be adapted to the teeth on either side of the upper jaw or the lower jaw.

The inner side wall of the fixed arm is provided with anti-slip threads, and the length of the fixed arm is 1.5-2.0 cm.

The thickness of the bottom of the main body of the dental pad is greater than that of the upper end, and the thickness of the bottom of the main body of the dental pad is 0.5-1.0 cm.

A suction hole with a diameter of 0.5-0.8 cm is opened on the side of the groove.

The depth of the outer surface of the alveolar is 0.5-0.8 cm, and the depth of the inner surface is 0.7-1.0 cm.

The length of the main body of the dental pad is 3-6 cm, and the distance between the bottom of the main body of the dental pad and the bottom of the alveolar is 1.0-1.5 cm.

Both the main body of the dental pad and the fixed arm are made of medical silica gel.

The utility model has the following beneficial effects: compared with the prior art, the utility model includes a dental pad main body, the top and the bottom of the dental pad main body are provided with alveolar; and one end of the dental pad main body is provided with a The groove; the groove is provided with an extended fixed arm; the main body of the dental pad is in an arc shape that can be adapted to the teeth on either side of the upper or lower jaw. When using, one or more can be selected according to the needs. First, let the patient's teeth bite the main body of the dental pad. Since the upper side of the main body of the dental pad is provided with an alveolar, the teeth of the upper or lower jaw of the patient can be accurately fixed in the alveolar. , which improves the stability of the device and can effectively avoid the displacement of the dental pad; since a groove and a fixed arm that match the endotracheal tube are provided at one end of the dental pad body, the endotracheal tube can pass through the fixed arm and the dental pad body The phase is fixed to prevent the catheter from falling off; and different placement positions can be selected according to the patient's position to meet the requirements of various operations, especially the prone position and other special positions; it can also protect the teeth to the greatest extent, especially the uneven dentition and incisors Patients who fall out can avoid iatrogenic injuries such as tooth loosening or even falling off. This device is suitable for large-scale promotion and use.

Furthermore, since the anti-slip thread is provided on the inner side wall of the fixed arm, the sliding of the cannula can be further prevented and the stability of the device can be ensured.

Further, since a phlegm suction hole is provided on the side of the groove, the phlegm and secretions in the patient's mouth can be sucked through the sputum suction hole, so as to ensure the patient's oral cavity clean and avoid other complications.

Furthermore, the material of the dental pad is medical silica gel with a certain degree of elasticity, so as to avoid damage to the patient's tongue, oral mucosa, teeth and their soft tissues by the device to the greatest extent, and at the same time reduce the cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1-2, the utility model includes a dental pad main body 1, and one side of the dental pad main body 1 is provided with an alveolar 3; The groove 2 is provided with a fixed arm 5 extending outward; the dental pad main body 1 is in an arc shape that can be adapted to the teeth on either side of the upper jaw or the lower jaw. An anti-skid thread is provided on the inner side wall of the fixed arm 5, and the length of the fixed arm 5 is 1.5-2.0 cm. The thickness of the bottom of the dental pad main body 1 is greater than that of the upper end, and the thickness of the bottom of the dental pad main body 1 is 0.5-1.0 cm. A suction hole 4 with a diameter of 0.5-0.8 cm is provided on the side of the groove 2 . The depth of the outer surface of the alveolar 3 is 0.5-0.8 cm, and the depth of the inner surface is 0.7-1.0 cm. The length of the dental pad main body 1 is 3-6 cm, and the distance between the bottom of the dental pad main body 1 and the bottom of the alveolar 3 is 1.0-1.5 cm. Both the dental pad main body 1 and the fixed arm 5 are made of medical silica gel.

When in use, first let the teeth on one side of the patient bite the dental pad main body 1, since the upper side of the dental pad main body 1 is provided with an alveolar 3, the teeth of the patient's upper or lower jaw can be accurately fixed in the dental alveolar 3, and the device is improved. Stability can effectively prevent patients from swallowing; because a groove 2 matching with the endotracheal tube is provided at one end of the dental pad main body 1, and a fixed arm 5 is provided at the groove 2, so that the endotracheal tube and the dental pad main body can be connected Phase 1 is fixed to prevent the cannula from slipping during the operation, thereby avoiding the device from wearing the patient's tongue, oral mucosa and tooth soft tissue to the greatest extent. Choose the installation location to meet the requirements of special postures in the operation. An anti-slip thread is provided on the inner side wall of the groove 2, so as to further prevent the intubation tube from sliding and ensure the stability of the device. A sputum suction hole 4 is provided on the side of the groove 2, so that the sputum and secretions in the patient's mouth can be sucked through the sputum suction hole 4, so as to ensure the patient's oral cavity clean and avoid other complications.
