Abstract
The utility model discloses a kind of dentistry aerosols and droplet pollutant negative pressure to concentrate excretion machine, it is fan-shaped gas collection column including cross section, side where the central angle of gas collection column lower end is provided with handle adaptation engaging, the fan-shaped circular arc side of gas collection column lower end is provided with negative port, gas collection capital face be provided with top negative pressure collect hole, the gas collection column side of the handle adapter side of closing set gradually there are two side negative pressure collect hole.The utility model size is small, convenient easily to move, and is adapted to most of dental instrument, can attract pollutant at the first time, avoid pollution object and cause cross-infection between staff and patient.
Description
Technical field
The utility model belongs to oral cavity blowdown technical field, and in particular to a kind of dentistry aerosol and droplet pollutant negative pressure
Concentrate excretion machine.
Background technique
In dental care, the universal only personal shielding protection such as mask glasses hand of the precautionary measures of promoting the circulation of qi colloidal sol and droplet
Set, patient's antimicrobial mouthwash.The atm number oral cavity of technology maturation or dentistry attract waste removal equipment only to apply in laboratory at present
Station environment.It is used in dental chair operating environment, attracts waste removal equipment size bigger than normal, terminal is heavy, is easy to influence medical matters
Personnel's operation, and contaminant collector port can not be applied to the happening part of aerosol and droplet at the first time.
Utility model content
The purpose of the utility model is to provide a kind of dentistry aerosols and droplet pollutant negative pressure to concentrate excretion machine, solves
The aerosol that generates when under dental chair environment between oral cavity health care worker and patient and droplet pollutant cross-infection are asked
Topic
The utility model is the technical scheme adopted is that dentistry aerosol and droplet pollutant negative pressure concentrate excretion machine, packet
Including cross section is fan-shaped gas collection column, and side where the central angle of gas collection column lower end is provided with handle adaptation engaging, gas
The fan-shaped circular arc side that body collects column lower end is provided with negative port, and gas collection capital face is provided with top negative pressure and collects hole, hand
The gas collection column side of the handle adapter side of closing set gradually there are two side negative pressure collect hole.
The utility model is also characterized by
Top negative pressure collection hole has been arranged radially multiple rows of along gas collection column sector top surface.
Negative port is connected with hose.
Handle adapter is combined into the ring-type that outer end is equipped with opening.
Air pressure balance, which is provided with, between negative pressure collection hole at the top of adjacent every row dredges lattice gear.
It is convenient easily to move the utility model has the beneficial effects that size is small, it is adapted to most of dental instrument, it can first
Time attracts pollutant, avoids pollution object and causes cross-infection between staff and patient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model dentistry aerosol and droplet pollutant negative pressure concentrate excretion machine；
Fig. 2 is the gas collection capital face knot that the utility model dentistry aerosol and droplet pollutant negative pressure concentrate excretion machine
Structure schematic diagram.
In figure, 1. top negative pressure collect hole, and 2. side negative pressure collect hole, 3. negative ports, the adaptation engaging of 4. handles, 5. gas
Body collects column, and 6. air pressure balances dredge lattice gear.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model dentistry aerosol and droplet pollutant negative pressure concentrate excretion machine, as Figure 1-Figure 2, including it is transversal
Face is fan-shaped gas collection column 5, and side where the central angle of 5 lower end of gas collection column is provided with handle adaptation engaging 4, and gas is received
The fan-shaped circular arc side of 5 lower end of clustered column is provided with negative port 3, and 5 top surface of gas collection column is provided with top negative pressure and collects hole 1, hand
Handle adaptation engaging 4 top 5 side of gas collection column set gradually there are two side negative pressure collect hole 2.
Negative pressure collection hole 1 in top has been arranged radially multiple rows of along the fan-shaped top surface of gas collection column 5.
Negative port 3 is connected with hose.
Handle adaptation engaging 4 is equipped with the ring-type of opening for outer end.
Air pressure balance, which is provided with, between negative pressure collection hole 1 at the top of adjacent every row dredges lattice gear 6.
The utility model dentistry aerosol and droplet pollutant negative pressure concentrate excretion machine, are made using Shooting Technique,
Operator holds general dental instrument handle one end when use, and the general dental instrument handle other end is fastened on handle adaptation engaging
In 4.Outside hub attraction system is connect with the hose of negative port 3, then starts central suction system, can be grasped
Make.Side negative pressure collects the colloidal sol and droplet pollutant on front side of when the attraction of hole 2 operates, the fan-shaped top surface layout of gas collection column 5
Increase collection surface, vacuum suction pollutant.
4 shapes of handle adaptation engaging can be adapted to most of dental instrument.
It is the throughput between equal part multiple rows of top negative pressure collection hole 1 that air pressure balance, which dredges 6 effect of lattice gear, is learned according to pneumatic
Venturi principle, air pressure balance, which dredges the high-speed flow in lattice gear 6, can generate negative pressure compensating in side negative pressure collection hole 2, guarantee
Multiple collection holes negative pressure is of substantially equal.
The utility model is elastomeric material TPE, and this material construction is low, and specific gravity is slim and graceful, and easy plastotype realizes functional structure,
It using considerable with economic value, itself is also easy to and general oral cavity equipment is compatible arranges in pairs or groups, and is easy docking hospital center suction
System.
