The structure comprises a micro air pressure valve, a hollow tube and a fixed seat, and is characterized in that the air pressure valve is an air bag body which can be cemented on teeth, and is provided with a pump, a hole and an air port for air to enter and exit, and the hollow tube is arranged in the hole; the hollow tube is a telescopic and zigzag tube body, one end of the hollow tube is arranged in the air pressure valve, and the other end of the hollow tube is arranged on the fixed seat; the fixing seat can be adhered to the teeth and is used for fixing one end of the hollow tube.

Description

Pressure tooth corrector

This utility model relates to the Dentition correcting device, refers to that especially the air pressure size in a kind of mat air pressure valve makes the hollow pipe air pressure valve and the relative application of force of holder, to correct the vapour-pressure type Dentition correcting device of denture.

Existing Dentition correcting has fixing and two kinds of primitive forms of removing property device, and the former utilizes ferrule (or claiming main line), and the various hookup mechanisms of welding on band cement in it on patient's tooth, fixes obtaining.On hookup mechanism,,, make tooth make various mobile purposes, also can directly the adhesion of line seat be fixed on the tooth to reach with camber line, auxiliary snap the line, spring etc. and firm the fixing of connector with ligature, nail, lock etc.The latter is welded into a shelf with metal wire usually, and welds snap ring, secondary spring etc. on the top of the shelf.Aforesaid way pushes away or during the strength of drawing in change, often needs constantly to transfer dress and is difficult for measuring application of force size, even may hinder tooth.

The purpose of this utility model is to have the above-mentioned shortcoming that Dentition correcting device exists now in order to overcome, and providing a kind of can handle rapidly, can be convenient to adjust the vapour-pressure type Dentition correcting device that obtains desirable application of force state again.

The purpose of this utility model is achieved in that vapour-pressure type Dentition correcting device, its formation comprises a micro pressure valve, a hollow pipe and a holder, it is characterized in that air pressure valve is the balloon-like body that can adhere on the tooth, the QI KOU that is provided with pump, hole and provides air to pass in and out is provided with hollow pipe in the hole; Hollow pipe is scalable, a zigzag body, and the one end is located in the air pressure valve, and end is located on the holder in addition; Can adhere to the holder on the tooth, fix for an end of hollow pipe.

Above-mentioned design forms malleation or negative pressure in the mat pump, hollow pipe is formed uphold or the power of contractions, make between air pressure valve and holder and form relative pulling force or thrust, thereby the tooth that forms its cementation causes the power of moving to certain direction.Only need to change the pump internal gas pressure, can adjust its application of force easily.

Below by drawings and Examples this utility model is described further again.

Fig. 1 is a cross-sectional schematic of the present utility model;

Fig. 2 is embodiment one sketch map of the present utility model;

Fig. 3 is embodiment two sketch maps of the present utility model;

Fig. 4 is a kind of structure cross-sectional schematic of the present utility model;

Fig. 5 is embodiment three cross-sectional schematic of the present utility model;

Fig. 6 is embodiment four cross-sectional schematic of the present utility model;

As shown in Figure 1: air pressure valve 1 contains pump 11, QI KOU 12 holes 13; Hollow pipe 2 one ends penetrate hole 13 and enter in the pump 11 and seal, be fixed in the pump, and the direction in hole 13 is the direction of strength.Air pressure valve 1 can be various moulding balloon-like, can adhere on the tooth, is provided with the non-return valve class device that belongs to prior art in the QI KOU 12, can inject thus or gas bleeding.Holder 3 is one can adhere to the plate body of tooth, and a nose bar 31 is set on it, for hollow pipe 2 end sealing in addition, fixing.Hollow pipe 2 is made for rubber, silica gel or plastic cement.Malleation in pump 11 forces hollow pipe 2 to stretch, and produces the thrust of air pressure valve 1 with holder 3, otherwise produces pulling force during negative pressure.Fig. 2 system is used to produce thrust and pushes tooth open situation, and the rig of tooth top serves as theme 4 and button 5.During pump malleation in air pressure valve 1, after tooth was open, hollow pipe 2 was stretched gradually.Fig. 3 is the state that tooth furthers, and be negative pressure in the pump 11, thereby the pulling force of 3 of formation air pressure valve 1 and holders, after tooth is furthered day by day, and hollow pipe 2 folding gradually.Pump 11 internal gas pressure sizes can be injected (or extracting out) gas from QI KOU 12 by the outside, are adjusted, and bear until structures such as suitable teeth, cooperate other correction tools again, form good Dentition correcting device.Shown in Figure 4: hollow pipe 2 is made up of the piston 6 and the body of rod 7, piston 6 impels piston 6 (or left side) direction motion to the right by the malleation in pump 11 left sides or negative pressure, the transmission of the mat body of rod 7, both cause fixed thrust or pulling force to make air pressure valve 1 and holder 3, and strength changes the position of tooth by this.Shown in Fig. 5,6: for by air pressure valve 1, piston 6, the body of rod 7 and holder 3 predetermined tooth is changed the situation of its position.Wherein Figure 5 shows that malleation in the pump 11, make air pressure valve 1 cause relative thrust with holder 3; Fig. 6 is then opposite.Air pressure valve 1 and holder 3 can generally be fixed and take off through bonding method with prior art.The air pressure valve mat syringe cylinder after being bonded on the tooth or the pump of inflating change the air pressure size in the pump 11, and be easy to use.

Claims (2)

1, vapour-pressure type Dentition correcting device, its formation comprise a micro pressure valve, a hollow pipe and a holder, it is characterized in that air pressure valve is the balloon-like body that can adhere on the tooth, and the QI KOU that is provided with pump, hole and provides air to pass in and out is provided with hollow pipe in the hole; Hollow pipe is scalable, a zigzag body, and the one end is located in the air pressure valve, and end is located on the holder in addition.

2, Dentition correcting device according to claim 1 is characterized in that wherein, hollow pipe is made up of the piston and the body of rod.
