Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental pad technology, specifically to an improved dental pad. Background Technology
[0002] A mouthguard, also known as a dental pad, is mainly used in emergency endotracheal intubation treatment to fix and prevent the patient's teeth from biting the endotracheal tube, thus avoiding affecting the normal operation of the intubation and reducing the workload of medical personnel to some extent.
[0003] Currently, dental pads are placed between the patient's upper and lower incisors during use. To ensure their stable placement in the oral cavity, a wing structure is provided on the outer surface of the pad's inlet end to help limit its position against the teeth. However, with prolonged use, pressure injuries caused by instruments can occur at the pressure points of the wing structures. These injuries are caused by continuous contact between the skin and tissues of medical or non-medical instruments (such as bedding, furniture, and equipment) used for diagnosis or treatment. The shape of these injuries usually matches the style or shape of the contacting instrument, thus creating new problems for subsequent treatment. Furthermore, the dental pads and endotracheal tubes are currently fixed together separately, making it easy for patients to push the dental pad out with their tongue or bite the tube. The structure still needs further improvement. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides an improved dental pad that solves the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: an improved dental pad, including a dental pad body and an insertion tube. The front surface of the dental pad body is attached to the rear surface of the insertion tube. A square hole is opened at the top of the dental pad body, and a tie is fitted inside the square hole. The two ends of the tie cross and wrap around the outside of the insertion tube for binding and both extend towards the rear end of the dental pad body.
[0006] The preferred embodiment has a clearance hole inside the dental pad body, and a first clearance groove is provided on the front and rear surfaces of the dental pad body. The first clearance groove can be fitted with the insertion tube to increase the connection force area, thereby improving the connection strength between the dental pad body and the insertion tube under the binding strap.
[0007] Preferably, the corner structure at the top of the dental pad body and the side of the top of the first relief groove, as well as the corner structure at the bottom of the dental pad body and the side of the bottom of the first relief groove, are all designed with rounded corners to maintain the comfort of the dental pad body in contact with the patient's oral cavity wall.
[0008] The preferred embodiment includes a neck cushion on the outer side of the dental pad body. A second clearance groove is provided at the rear end of the neck cushion. The second clearance groove can be movably engaged with the end of the tether. The neck cushion and the tether work together to bind and limit the patient's neck, ensuring the stability of the dental pad body in the patient's mouth. The structure of the neck cushion can increase the force-bearing area between the patient's neck and the tether, reduce the binding pressure of the tether, and improve comfort.
[0009] The neck cushion has several ventilation holes inside, which are arranged in an array along the circumference of the neck cushion. The multiple ventilation holes maintain the ventilation effect of the neck cushion during use, avoid prolonged use without breathability, and maintain the comfort of the patient's neck in contact with the neck cushion.
[0010] The neck cushion has rounded corners on both the edges and the corners of the ventilation holes. This ensures the comfort of the neck cushion and ventilation holes when in contact with the patient's neck skin during use. The neck cushion is made of rubber or silicone material, providing flexible support and elastic deformation during subsequent use to meet the needs of patients with different body shapes.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This utility model is an improved dental pad composed of a dental pad body and a square hole, a first clearance groove, and a clearance hole on the dental pad body structure. After being used with a tether and an insertion tube, it can ensure the high-strength connection effect of the dental pad body and the insertion tube through multiple interconnected assembly, while ensuring good stability of the improved dental pad and the insertion tube in the patient's mouth through further binding and limiting with the patient's neck.
[0013] 2. The improved dental pad proposed in this utility model has no side wing structure compared with the traditional dental pad. Therefore, during long-term use with the ties and the dental pad body, it can avoid mechanical pressure damage caused by structural pressure.
[0014] 3. This utility model consists of a multi-functional auxiliary installation structure composed of a neck cushion, a second clearance groove inside the neck cushion, and several ventilation holes. When used in combination with the aforementioned improved bite pad, ties, and cannula, the neck cushion can increase the binding force area between the patient's neck and the ties, reduce the binding pressure of the ties, and improve comfort. The several ventilation holes can maintain the ventilation effect of the neck cushion during use, avoid prolonged use without breathability, and maintain the comfort of the contact position between the patient's neck and the neck cushion.
