First chamber 1041 is connected.The drainage channel 24 is used in the impeller 1031 along the diminution portion 1042 to away from the diminution
When the direction of the first chamber 1041 in portion 1042 is moved, by what is flowed into from the gap in the diminution portion 1042 and the stop valve 102
High pressure low temperature liquid gas is drained to the first flow 23.
As shown in figure 1, can recover to initial bit when the operation forces disappear in order that obtaining the brake assemblies 103
Put, the brake assemblies 103 can also include the second reset element.The second reset element one end and second support component 106
It is connected, the other end is connected with the brake component 1032.Second reset element is configured to when the flow channel is opened, should
The operation forces of brake component 1032 act on second reset element so that second reset element is deformed upon and in pressure
Contracting state, and when the operation forces of the brake component 1032 disappear, second reset element can drive the brake component 1032
Moved towards near the direction of the nozzle 107, to close the flow channel.Additionally, the stroke in order to limit brake component 1032, can
Spacing hole 1061 is opened up with the surface of the second support component 106.
It is the third flow channel 11, second flow channel 12, first chamber 1041, first-class in the embodiment shown in Fig. 1 to Fig. 3
The runner 1071 of road 23 and the 4th constitutes the flow channel together.Additionally, the controllable spray in order to further realize cryogen, should
Casting die 201 can also be set in first chamber 1041.The one end of casting die 201 connect the first reset element 105, the other end near or
Contact ejector pin mechanism 101.The casting die 201 is hollow, and the hollow structure forms the 5th runner 2011, the 5th runner 2011
Size of the size less than first chamber 1041.By setting the casting die 201, equivalent to extending from steel cylinder 108 to stop valve 102
Distance, simultaneously because the setting of the 5th runner 2011 reduces the flow rate of cryogen, therefore, it is possible to more accurately
Control the flow of cryogen.Now, according to third flow channel 11, second flow channel 12, the 5th runner 2011, first chamber 1041,

Circle.
With reference to the injection cold therapy device 100 of the embodiment of above-mentioned Fig. 1 to Fig. 3, it includes three kinds of states, respectively steel bottle
The state of the moment that the diaphragm seal at mouth 1081 is punctured, diaphragm seal are punctured state and system after rear brake component 1032 is operated
The state when operation forces of moving part 1032 disappear.Although it is understood that being a width figure in Fig. 1, it includes two
State before diaphragm seal at kind of state, i.e. steel bottle mouth 1081 is punctured and after being punctured.This is due in both states
Under, simply the slight change of the position of stop valve 102, this slight change, do not reflect in figure.
As shown in figure 1, the principle of the state of the moment that the diaphragm seal at the steel bottle mouth 1081 is punctured is：With the steel
The rotation of bottle cover part 109, syringe needle 1011 is contacted and punctures diaphragm seal, and the cryogen in steel cylinder 108 is suitable with the second injection pressure
Sequence sprays into third flow channel 11, second flow channel 12, the 5th runner 2011 and first chamber 1041 so that be arranged on first chamber 1041
Interior stop valve 102 is promptly pushed up to being close at the first chamber 1041 in diminution portion 1042, in one embodiment, due to cutting
Only the first end face of valve 102 is not belonging to rigid material, so that cryogen can be sealed in third flow channel 11, second
In road 12, the 5th runner 2011 and first chamber 1041.
As shown in figure 3, the principle that the diaphragm seal is punctured the state after rear brake component 1032 is operated is：In the brake component
1032 when being promoted, and it drives impeller 1031 to be moved to the direction away from nozzle 107, and the impeller 1031 drives cut-off therewith
Move in direction of the valve 102 along first chamber 1041 away from nozzle 107 so that be sealed in third flow channel 11, second flow channel
12nd, the cryogen in the 5th runner 2011 and first chamber 1041 is sprayed into from the gap of diminution portion 1042 and stop valve 102
The drainage channel 24 of impeller 1031, and then order sprays into the runner 1071 of first flow 23 and the 4th, and by the spray of the nozzle 107
Sprayed with the first injection pressure at mouthful.Wherein it is possible to regulate and control cryogen by adjusting the operating time of brake component 1032
Dosage.
The principle of the state when operation forces of brake component 1032 disappear is：When acting on the operation at brake component 1032
When active force disappears, the brake component 1032 is moved under the active force of the second reset element towards near the direction of nozzle 107, with
Recover to initial position, now, stop valve 102 is under the active force of the first reset element 105 towards near diminution portion 1042
Direction is moved, and cryogen is continued to be sealed in third flow channel 11, second flow channel 12, the 5th runner 2011 and first chamber
In 1041.
Fig. 4 shows the schematic flow sheet of the application method of injection cold therapy device according to an embodiment of the invention.It is special

S200, rotation steel cylinder external member are to cause that ejector pin mechanism punctures the diaphragm seal at steel bottle mouth and cryogen is close
It is enclosed in third flow channel, second flow channel, the 5th runner and first chamber；
S300, pressing brake component, to promote direction of the stop valve along first chamber away from nozzle to move, to cause
Cryogen is sprayed with the first injection pressure from nozzle；
S400, take-off the brake part, to cause stop valve under the active force of the first reset element towards near diminution portion
Direction is moved, and cryogen is continued to be sealed in third flow channel, second flow channel, the 5th runner and first chamber.
For cryogen accurately is injected in into focal area, without causing to damage surrounding normal tissue, it is necessary to control
Pressed repeatedly and take-off the brake part during treatment.Injection cold therapy device in the present invention steady and can be realized promptly in steel cylinder
The injection and stopping injection of high pressure cryogenic fluid, and press and also taken into full account user's with the implementation method of take-off the brake part
Experience, is easy to operation.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple of the invention and show
Example property embodiment, but, without departing from the spirit and scope of the present invention, still can be direct according to present disclosure
It is determined that or deriving many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognizes
