The universal support arm which can freely stretch and bend is composed of a plurality of hollow pipe pieces in pivot connection; the ffront end of the support arm is provided with flexible bodies which are connected with the cover bodies; the universal support arm can be pivoted on a support shaft of a lamp or be supported on one side of the headrest. When used, the cover bodies are placed near the mouth of a patient, mist around the mouth of the patient, which is absorbed by the suction machine, is filtered to be clean air, to keep indoor sanitation, and to prevent from infection.

Description

Dentist's workbench dust exhaust apparatus

This utility model relates to a kind of dentist's workbench dust exhaust apparatus, belongs to a kind of medical device.

When odontologist works; for stressing health, often wear masks and filter, but this method often can not stop the infection of antibacterial really from the gas in patient's mouth; especially control in the tooth process and often to need the car tooth of grinding one's teeth in sleep; the centrifugal force that is produced when the rotation of car grinding machine sprays patient's saliva and blood and slime in patient's mouth, and nebulizes when being spread in the air, and patient such as body dye infectious disease; the dentist is just very dangerous; in addition, dentist's workbench regular meeting makes a face fog, and is very unhygienic.Sometimes, because of medical personnel do not have the custom that wears masks, infectivity disease and influence indoor other patient more.

The purpose of this utility model is that a kind of dentist's workbench dust exhaust apparatus will be provided, and this device can be absorbed the fog that sprays in patient's mouth, and the dentist is healthy in protection, prevents communicate illness.

The purpose of this utility model is achieved in that dentist's workbench dust exhaust apparatus, by universal support arm, cover body and the vacuum cleaner being located at the ventilation duct of universal support arm inside and being incorporated into the ventilation duct two ends respectively constitute, the universal support arm that can freely bend and stretch is closed by many hollow pipe fitting pivots and forms, supporting arm front end is provided with flexible body, flexible body is connected with cover body, universal support arm can be hubbed on the fulcrum of light fixture or be set up in workbench one side, during use cover body placed the patient mouth, borrow vacuum cleaner that fog around the patient mouth is sucked, be filtered into pure air, health in the holding chamber, and protect from infection.

This utility model advantage:

1, because of using the appended flexible body of universal support arm and front end thereof, can freely bend and stretch, with the need cover body be placed the patient mouth, produce fog in will working by means of ventilation duct and get rid of, so easy to use.

2, because of being provided with the interlayer that is interconnected in vacuum cleaner inside, comprising devices such as drainage screen, ultraviolet sterilizations,, guarantee air cleaning so disinfection filtering is thorough, it is healthy to help medical personnel, prevents to pollute.

3, because of dust suction in this utility model with cover body and universal support arm can with workbench lampshade employee, design is combined into one, thereby can reduce cost by simplified structure.

This utility model concrete structure is provided by following examples and accompanying drawing thereof.

Fig. 3 is this utility model embodiment two sketch maps;

Fig. 4 is this utility model embodiment three sketch maps;

Fig. 5 is the local enlarged diagram of Fig. 4;

Fig. 6 is inner various filter materials of this utility model vacuum cleaner and device sketch map;

Describe in detail below in conjunction with accompanying drawing:

Referring to Fig. 1-6, dentist's workbench dust exhaust apparatus, constituted by universal support arm 10, cover body 20 and the vacuum cleaner 30 being located at the ventilation duct of universal support arm 10 inside and being incorporated into the ventilation duct two ends respectively, it is characterized in that: universal support arm 10 is closed by many hollow pipe fittings 11 pivots and forms, support arm 10 front ends are provided with flexible body 12, and flexible body 12 is connected with cover body 20.

Described vacuum cleaner 30, be provided with air intake 31, be provided with motor M in air intake 31 1 sides, the outfan of motor M is provided with air exhauster 32, vacuum cleaner 30 inside are provided with the interlayer 33 that is interconnected, and being positioned at air exhauster 32 belows is the accumulation area 34 of catchmenting, in the motor M and accumulation area 34 1 sides of catchmenting, be sequentially with drainage screen 35, ultraviolet sterilization district 36, activated carbon layer 17, drainage screen 35 and air outlet 38.

Figure 1 shows that this utility model embodiment one, described universal support arm 10 is hubbed on the fulcrum 40 of light fixture, and patient 60 lies on the workbench 50, and lampshade 70 separates with cover body 20 mutually with this device.

Fig. 2 is the side view of Fig. 1.

Figure 3 shows that this utility model embodiment two, described universal support arm 10 is set up in a side of workbench 50.

Figure 4 shows that this utility model embodiment three, described cover body 20 is combined into one with lampshade 70 designs, both shared universal support arms, thus simplified structure is saved cost.

Fig. 5 is Fig. 4 part partial enlarged drawing.

When this utility model embodiment one uses, utilize universal support arm 10 and flexible body 12 to turn round cover body 20 and move to patient 60 mouths, when dentist's car grinds patient 60 tooth, saliva that is sprayed and blood and slime can be inhaled in the vacuum cleaner 30 from cover body 20, whirlwind via air exhauster 32 running generations, blood and slime and saliva are sought connections with on wall, concentrate on again in the accumulation area 34 of catchmenting, residue has foreign gas through filter screen 35, ultraviolet sterilization district 36, activated carbon layer 37, discharges clean air at last at drainage screen 35 filtrations, sterilization, deodorization.Other embodiment usage is broadly similar therewith also.
