Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an anesthesia dental pad. Background Art
[0002] In recent years, the number of endotracheal intubation general anesthesia in hospitals at all levels has increased, and the trend of aging patients has become more and more obvious. Because patients are in anesthesia, they will involuntarily clench their teeth, which will cause the endotracheal tube in the patient's mouth to be compressed and then closed, increasing the risk of emergency airway in patients. For this reason, during endotracheal intubation general anesthesia, it is necessary to add a tooth pad to the patient's mouth. The tooth pad has a channel for installing the endotracheal tube, so that the patient bites on the tooth pad made of harder material, which will not compress the endotracheal tube in the tooth pad, thereby ensuring that the patient's airway is unobstructed.
[0003] When the bite block is in use, the depth of the endotracheal tube needs to be controlled, so the bite block can slide on the endotracheal tube. The bite block located in the patient's mouth has no fixing effect on the endotracheal tube. If the endotracheal tube is subjected to external force after installation, it is easy to slide inside the bite block, affecting the patency of the patient's airway.
[0004] Therefore, a technical solution is currently needed to solve the technical problem that during endotracheal intubation general anesthesia, the dental pad has no fixing effect on the endotracheal tube, and the endotracheal tube is easily displaced after being subjected to external force, thus affecting the patient's airway patency. Utility Model Content
[0005] The invention purpose of the utility model is to provide an anesthesia bite pad to solve the technical problem that during endotracheal intubation general anesthesia, the bite pad has no fixing effect on the endotracheal tube, and the endotracheal tube is easily displaced after being subjected to external force, which affects the patency of the patient's airway.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] An anesthesia bite pad comprises a bite pad body, wherein the bite pad body is provided with a channel for placing an endotracheal tube, one end of the channel is nested and connected with a limit plug, the limit plug is an elastic material structural part, and the limit plug is provided with a mounting hole adapted to the diameter of the endotracheal tube.
[0008] The utility model discloses an anesthesia bite pad. When in use, the bite pad is put on the endotracheal tube. After the endotracheal tube is installed, the position of the bite pad is adjusted so that the bite pad is located in the oral cavity of the patient. Then a limit plug is inserted into one end of the bite pad body. The limit plug is elastically embedded in the one end of the bite pad body, and the endotracheal tube is pressed into the installation hole inside the limit plug. Thus, the endotracheal tube and the bite pad body are relatively fixed, which plays a certain stabilizing role on the endotracheal tube and improves the guarantee of unobstructed airway of the patient.
[0009] As a preferred solution of the utility model, the end of the stopper is provided with a butt ring, and the butt ring is used to butt against the end of the tooth pad body. When the stopper is embedded in the channel, the butt ring at the end of the stopper butts against the end of the tooth pad body to limit the stopper, so that the stopper can be pulled out of the tooth pad body after use.
[0010] As a preferred solution of the utility model, the stopper includes at least two stopper petals, each of which is provided with an arc-shaped groove, and all of the arc-shaped grooves enclose the installation hole. The two-petal stopper can be installed or removed on the bite block body after the endotracheal tube is installed, making the installation and removal of the stopper easier.
[0011] As a preferred solution of the utility model, the number of the plug petals is two, and the two plug petals are symmetrically arranged. The number of the plug petals is set to two to minimize the number of plug petals, which not only makes the disassembly and assembly of the limit stopper most convenient, but also facilitates the manufacture of the plug petals.
[0012] As a preferred solution of the utility model, the side wall of the tooth pad body is connected with a baffle, and the baffle is arranged around the tooth pad body. When in use, the baffle abuts against the patient's lips to limit the tooth pad and prevent the tooth pad from falling completely into the patient's mouth.
[0013] As a preferred solution of the utility model, the two sides of the baffle are respectively provided with hanging holes, and the hanging holes are tied with cable ties. The entire dental pad can be fixed to the patient's head by the cable ties to prevent the dental pad from slipping off.
[0014] As a preferred solution of the utility model, a evacuation hole is provided on one side of the baffle. The evacuation hole is provided close to the tooth pad body, which can facilitate medical staff to insert a suction tube into the patient's mouth through the evacuation hole, so as to facilitate the suction operation of the patient's oral secretions while intubating the trachea.
[0015] As a preferred solution of the utility model, the tooth pad body is sleeved with an elastic pad, and the elastic pad is arranged on one side of the baffle. The patient's teeth are in contact with the tooth pad body sleeved with the elastic pad, which plays a role in protecting the patient's teeth and oral tissues.
[0016] As a preferred solution of the utility model, the surface of the elastic pad is evenly provided with anti-slip strips, and the anti-slip strips are arranged around the surface of the elastic pad. The anti-slip strips can increase the friction with the patient's teeth and reduce the sliding of the tooth pad in the patient's mouth, thereby ensuring that the patient's airway is unobstructed.
[0017] As a preferred solution of the utility model, a limiting ring is provided at one end of the tooth pad body, and the elastic pad is sleeved between the limiting ring and the blocking piece. The limiting ring has a limiting effect on the elastic pad sleeved on the tooth pad body, which can prevent the elastic pad from loosening under the patient's bite during use.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0019] The present application adds a detachable limit plug to the bite block body. After the bite block body and the endotracheal tube are installed, the endotracheal tube and the bite block body are relatively fixed by the limit plug made of elastic material. In this way, the endotracheal tube is not easy to slide under the patient's occlusion, thereby improving the safety of the patient's airway. BRIEF DESCRIPTION OF THE DRAWINGS
