Description

Isolating device for isolating droplet propagation in oral treatment

Technical Field

The utility model belongs to the technical field of dental medical instrument, specifically be an isolation device who separates the propagation of droplet when being used for oral treatment.

Background

In the dental treatment process, the high-speed turbine cuts teeth after cooling by water spray in the oral cavity, but simultaneously splashed liquid is mixed with saliva of a patient to generate a large amount of spray and aerosol, however, in the treatment process, the oral cavity and the nasal cavity of the patient are always kept in an open state and are directly exposed in the environment of a consulting room, so that a possible path for spreading infectious diseases is formed, and particularly during epidemic outbreak of respiratory infectious diseases, a device for effectively isolating the patient is needed to avoid exposing the patient to the splashed liquid.

In addition, various disinfection solutions are commonly used in dental treatment, and some high-concentration disinfection solutions, such as the commonly used 5% sodium hypochlorite solution, are very irritating to tissues, and can cause serious injury if the skin or mucous membrane of a patient, particularly conjunctiva of eyes, is carelessly contacted.

In the existing dental treatment process, a rubber dam isolation technique is usually adopted, a rubber film with good elasticity is used for isolating the position of a tooth as required, a small hole is punched on the film to be sleeved in the affected tooth, and the elasticity of the rubber dam is used for tightly hooping the neck of the tooth to isolate the neck from the oral environment. However, the face arch used for the dam isolation is small, only the oral cavity is isolated, and the nasal face of the patient is still exposed to the outside. The breath may still come into contact with the therapeutic spray, resulting in the generation of a contaminating aerosol. In addition, the patient's face is not effectively isolated, which all present a safety hazard.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide an isolating device for isolating pollution droplets during oral treatment, which provides comprehensive protection and helps the nasal cavity and the eye conjunctiva of a patient to avoid being exposed in the dental treatment environment.

In order to achieve the above object, the utility model provides a following technical scheme:

an isolating device for isolating droplet propagation in oral treatment comprises an inner ring face bow attached to the periphery of an oral cavity and an outer ring face bow for shielding a face part, wherein the inner ring face bow and the outer ring face bow are connected in a sealing manner through a rubber cloth to form a horn-shaped structure; the upper part of the outer ring face bow is connected with a bracket component for supporting the nose space.

Further, the inner ring face bow is used for placing a finished product rubber dam face bow, and the caliber of the inner ring face bow is smaller than that of the finished product rubber dam face bow.

Furthermore, the bracket component is two head straps respectively arranged at two ends of the outer ring face bow.

Furthermore, a plurality of anti-skid protrusions are densely distributed on the inner wall of the head hoop strip.

Furthermore, the bracket component is two bendable metal wires respectively arranged at two ends of the outer ring face bow.

Furthermore, the periphery of the bendable metal wire is wrapped with an anti-slip shell.

Has the advantages that: the utility model provides an isolating device that separates droplet and propagate when being used for oral treatment, the device can guarantee that the affected tooth of dentistry treatment keeps apart with patient's oral cavity and face completely, effectively avoids the liquid among the treatment process to contact the risk of patient's face, and the patient breathes with the nose in the treatment process simultaneously, and can directly not inhale the liquid drop of treatment in-process spill, also can avoid inhaling the contaminated aerosol of treatment in the consulting room under the condition of cooperation new trend system. Even in the outbreak period of respiratory infectious diseases, the effective isolation and protection of patients can be ensured, and the treatment of oral diseases is not obstructed. Thus, the device is suitable for general use in dental treatment.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. The present invention will be further explained with reference to the accompanying drawings.

An isolating device for isolating droplet propagation in oral treatment comprises an inner ring face bow 1 attached to the periphery of an oral cavity and an outer ring face bow 2 for shielding a face part, wherein the inner ring face bow 1 and the outer ring face bow 2 are connected in a sealing manner through a rubber cloth 3 to form a horn-shaped structure; the upper part of the outer ring face bow 2 is connected with a bracket component for supporting the nasal space, thereby ensuring that the patient can breathe smoothly.

The inner ring face bow 1 is used for placing a finished product rubber dam face bow, the caliber of the inner ring face bow 1 is smaller than that of the finished product rubber dam face bow, and the finished product rubber dam face bow is adhered to a rubber blanket by using the elasticity of the rubber blanket 3 so as to be tightly fit with the inner ring face bow 1.

As an implementation mode, the bracket component is two head hoop strips 4 respectively arranged at two ends of the outer ring face bow 2, a plurality of anti-skidding protrusions are densely distributed on the inner wall of each head hoop strip 4, the nose space can be supported by adjusting the front and back positions of the head hoop strips 4 at the fixed position of the head, and the head hoop is more firmly fixed on the head due to the arrangement of the anti-skidding protrusions. As another embodiment, the bracket assembly is two bendable wires 5 respectively disposed at two ends of the outer ring face bow 2, and the bendable wires can support the nasal space by using their toughness and facilitate the fixation on the head by using their bendability, so as to adjust the wearing position and fix the device by winding and locking the ends of the two bendable wires 5.
