Abstract
The utility model is used for the ceramic vacuum chamber of proton therapeutic appts, the ceramic vacuum chamber includes the first ceramic tube (2), the second ceramic tube (5), pass through middle seal ring (3) between first ceramic tube (2), the second ceramic tube (5) to connect, the end of first ceramic tube (2) is provided with flange (1), the end of the second ceramic tube (5) is provided with sealing ring (4).Described the first ceramic tube (2) inner wall surface is provided with conductive layer (6).Described the second ceramic tube (5) inner wall surface is provided with conductive layer (6).For the utility model the utility model has the advantages that reasonable in design, novel, high vacuum, volume are big, cheap, proton beam efficiency of transmission is high, therapeutic effect is good.
Description
Technical field
The utility model relates to electrovacuum fields, and in particular to the ceramic vacuum chamber for proton therapeutic appts.
Background technique
Vacuum tank uses under high-frequency ac electric field or alternating magnetic field, cannot be with greatly due to that can generate current vortex effect
The metal of section manufactures, therefore can use ceramic vacuum chamber, and the primary structure of ceramic vacuum chamber is electrovacuum ceramics pipe, electrovacuum
Ceramic tube is to be formed using isostatic pressing method, hot drape process or cold casting, using aluminium oxide as raw material through high temperature sintering, high-temperature glaze
The multiple tracks techniques such as burning are made, therefore can not do the volume of ceramic vacuum chamber greatly；Furthermore the existing proton therapeutic appts of being used in
Ceramic vacuum chamber is the core key part of the medical equipment of the first treating cancer in China, since the structure of ceramic vacuum chamber is more
For H-type, therefore therapeutic effect is not achieved most preferably；In addition it is fitted without conductive layer in existing ceramic vacuum chamber, so in matter
Energy loss is larger during sub- beam transfer, easily causes ceramic vacuum chamber fever, generates security risk.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, propose it is a kind of it is reasonable in design, novel,
High vacuum, volume are big, cheap, proton beam efficiency of transmission is high, the good ceramics for proton therapeutic appts of therapeutic effect
Vacuum chamber.
The utility model is used for the ceramic vacuum chamber of proton therapeutic appts, and the ceramic vacuum chamber includes the first ceramic tube
2, the second ceramic tube 5 is connected between first ceramic tube 2, the second ceramic tube 5 by middle seal ring 3, in the first ceramic tube 2
End be provided with flange 1, the end of the second ceramic tube 5 is provided with sealing ring 4.
First ceramic tube, 2 inner wall surface is provided with conductive layer 6.
Second ceramic tube, 5 inner wall surface is provided with conductive layer 6.
Closing is collectively formed in the sealing ring 4 of first ceramic tube 2, the second ceramic tube 5, top flange 1, bottom setting
Formula space.
The enclosed space vertical sectional shape is trapezium structure.
The utility model for proton therapeutic appts ceramic vacuum chamber the utility model has the advantages that
1) ceramic vacuum chamber described in includes the first ceramic tube 2, the second ceramic tube 5, first ceramic tube 2, second
It is connected between ceramic tube 5 by middle seal ring 3, by the splicing of the first ceramic tube 2, the second ceramic tube 5, increases entire ceramics
Vacuum chamber volume increases the volume of ceramic vacuum chamber interior, the high energy proton line for enabling proton therapeutic appts to generate
More, it uninterruptedly, nondestructively transmits；
2) sealing ring 4 of the first ceramic tube 2, the second ceramic tube 5 described in, top flange 1, bottom setting is collectively formed
Enclosed space, the enclosed space vertical sectional shape are trapezium structure, and not only stability is good, but also in the process for the treatment of
In enable proton therapeutic appts generate high energy proton line more accurately attack lesion directly, reach good effect of curing the disease
Fruit；
3) the first ceramic tube 2,5 inner wall surface of the second ceramic tube described in are provided with conductive layer 6, improve the biography of proton beam
Defeated efficiency, resistance is small, energy loss is low, and ceramic vacuum chamber fever phenomenon is reduced, while reducing security risk；
4) reasonable in design, novel, high vacuum, volume are big, cheap, therapeutic effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: flange 1, the first ceramic tube 2, middle seal ring 3, sealing ring 4, the second ceramic tube 5, conductive layer 6.
Specific embodiment
Below with reference to attached drawing 1, the utility model is described in further detail.
The utility model is by flange 1, the first ceramic tube 2, middle seal ring 3, sealing ring 4, the second ceramic tube 5,6 groups of conductive layer
At specific structure are as follows: the ceramic vacuum chamber includes the first ceramic tube 2, the second ceramic tube 5, first ceramic tube
2, it is connected between the second ceramic tube 5 by middle seal ring 3, the end of the first ceramic tube 2 is provided with flange 1, in the second ceramic tube 5
End be provided with sealing ring 4.First ceramic tube 2,5 inner wall surface of the second ceramic tube are provided with conductive layer 6.Described
Enclosed space is collectively formed in the sealing ring 4 of first ceramic tube 2, the second ceramic tube 5, top flange 1, bottom setting.Described
Enclosed space vertical sectional shape is trapezium structure.
It is installed on proton therapeutic appts and is used cooperatively when use, meet proton therapeutic appts to ceramic in ceramic vacuum chamber
Particular/special requirement, i.e. for resistance less than 10 ohm, conductive layer thickness optimizes ceramic and metal jointing structure and technique less than 0.1 μm,
Vacuum leak rate reaches 1 × 10-11Pa.m3/ s the order of magnitude guarantees the requirement of proton therapeutic appts condition of high vacuum degree.
