Technical Field
The invention relates to the technical field of dislocation tooth emergency treatment, in particular to a portable device for dislocation tooth emergency treatment and preservation.
Background
Dislocation refers to the situation that the teeth are partially or completely separated from the alveoli after being subjected to external force. Depending on the degree of dislocation of the teeth, it can be classified into incomplete dislocation, complete dislocation and embedded dislocation. The incomplete dislocation means that the teeth deviate from the original positions but are not completely separated from the alveolus, the complete dislocation means that the teeth completely leave the alveolus, and when the teeth are completely dislocated, a storage device is needed to carry out emergency treatment on the dislocated teeth.
Through searching, chinese patent with publication number CN219070735U discloses a dislocation tooth storage processing box, which comprises a box body and a box cover, wherein one side of the box cover is hinged with the box body, and the other side of the box cover is detachably connected with the box body. The box body is internally provided with a cleaning tank, a liquid storage tank, a tooth storage tank and a storage tank. The cleaning groove and the tooth storage groove penetrate through the bottom of the box body, and a sealing plug is detachably connected to the bottom of the corresponding box body.

Tweezers are detachably connected in the storage groove.
Based on the above search in combination with the prior art, it has been found that most of the current dislocated teeth are placed in a cavity. The temporary storage is carried out, however, the cavity of most storage devices is far larger than the dislocation teeth, the dislocation teeth cannot be properly fixed, the dislocation teeth roll in the cavity easily in the transportation process and are easy to generate accidental damage, on the other hand, the shelf life of the unsealed milk is shorter, and in actual operation, the milk is temporarily added to carry out emergency treatment on the dislocation teeth, so that in operation, the steps of preparing the milk and pouring the milk are additionally required, the emergency treatment is not facilitated, and the limitation exists.
