Description

Emergency department prevents tongue device of clenching with epileptic

Technical Field

The invention relates to the field of emergency department equipment, in particular to a tongue biting prevention device for an epileptic in an emergency department.

Background

The reasons for epilepsy are mainly craniocerebral trauma meningitis or intrauterine asphyxia and oxygen deficiency, and the clinical manifestations of epilepsy patient are sudden consciousness loss, followed by clonic spasm after rigor and, dark purple complexion, tongue bite, white foam or blood foam in mouth and mydriasis, and the spasm attack naturally stops after lasting for tens of seconds or minutes, and enters a narcolepsy state.

The epileptic seizure has a tongue biting condition, so that the medical personnel in the emergency department need to roll handkerchief, gauze and the like into a roll before the mouth of the patient is closed tightly when the epileptic seizure occurs, and the handkerchief, the gauze and the like are padded between the upper teeth and the lower teeth of the patient, so as to prevent the tongue from being bitten when the teeth are closed tightly.

The applicant finds that at least the following technical problems exist in the prior art: when the mouth of the patient is in a closed state due to muscle contraction, medical staff needs to manually open the mouth of the patient or pry the mouth of the patient by using a tool so as to plug the anti-biting tongue protection pad into the mouth of the patient while avoiding the tongue biting danger of the patient. However, in the operation process, if the medical staff opens the oral cavity of the patient by hands, the hands of the medical staff can contact the teeth of the patient closely, so that the risk of being bitten by the medical staff exists, and the safety of the medical staff cannot be guaranteed; when the medical staff prys the mouth of the patient by using the tool, the mouth of the patient can be pried by using the tool with higher hardness only because the teeth of the patient are harder, but the risk of breaking the teeth of the patient is easily caused in the prying process by adopting the mode, and the safety of the patient cannot be ensured; simultaneously, the two operations all need multiple medical workers to operate in a coordinated mode, and time and labor are wasted.
