The specific embodiment
Below in conjunction with accompanying drawing the present invention and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-3, the present invention includes double-layer vacuum fluid reservoir, liquid-feeding tube, tube for transfusion and exhaustor, it is characterized in that:
In the interlayer of A, described double-layer vacuum fluid reservoir 1, be provided with supercharger 2, this supercharger is communicated with the top of double-layer vacuum fluid reservoir 1 by electromagnetic valve 1 or hand-operated valve 1;
B, described tube for transfusion 5 are the tube for transfusions with electromagnetic valve 26 and hand-operated valve 27, and the one end inserts in the liquid nitrogen of double-layer vacuum fluid reservoir, and the other end is connected with refrigerator;
C, described liquid-feeding tube 12, the one end inserts the top of double-layer vacuum fluid reservoir 1, and the other end is connected with the liquid nitrogen input pipe by check valve 9;
D, described exhaustor 13, the one end inserts the top of double-layer vacuum fluid reservoir 1, and the other end is communicated with atmosphere by hand-operated valve 38.
Described supercharger 2 is helical form copper tube superchargers.
Referring to Fig. 1,1 is from the supercharging fluid reservoir, be welded by double-layer stainless steel, outer wall cloth has helical form copper tube supercharger 2 between middle vacuum pumpin layer, its the lower end mouth of pipe and interior tank bottoms communicating, liquid nitrogen can enter wherein, the upper end mouth of pipe communicates with inner canister top by valve 3, the copper tube of being close to outer tank absorbs the liquid nitrogen vaporization that causes from the heat of outer tank conduction in the supercharger, by electromagnetic valve 1 or hand-operated valve one 4 foldings, nitrogen in connection and the isolated supercharger after the vaporization enters liquid nitrogen container top, reaches the purpose of control tank internal pressure.Under pressure, liquid nitrogen is forced out by tube for transfusion, by electromagnetic valve 26 or hand-operated valve 27 its break-makes of control, treats for being connected with refrigerator.8 is air bleeding valve (hand-operated valve three), when injecting liquid nitrogen in the tank and treatment all need open after finishing, all the other times all are in closed condition.The liquid-feeding tube seam has special nonstandard one-way cock 9, automatically opens as long as load onto liquid injection pipe during liquid feeding, and liquid injection pipe is then closed after removing voluntarily.10 is Pressure gauge, and 11 is relief valve.
Referring to Fig. 2,21 is refrigerator (cryoprobe), by red copper or silver manufacturing, in the hope of obtaining high pyroconductivity.Refrigerator links to each other by the outer steel pipe of nut 19 and handle, be lined with teflin ring 17 therebetween, in handle rustless steel outer tube, rustless steel inner tube 16 and shower nozzle are housed, the handle left end links to each other with plastics outer flexible tube 14 and inner flexible tube 15, is connected on the tube for transfusion of machine, during treatment, liquid nitrogen is by inner flexible tube 15, interior steel pipe 16, by the shower nozzle ejection, through after vaporizing with the exchange of pathological tissues body temperature heat by conduction, nitrogen is overflowed through the space between the inner and outer pipes at refrigerator 21 heads.
For adapting to various focus, the machine has when a refrigerator (probe) that overlaps shape and different sizes supplies treatment and selects.
Referring to Fig. 3, Switching Power Supply and control circuit are by one of isolating transformer, and Switching Power Supply two covers and power supply adaptor one cover form, and are respectively the power supply of system, control circuit plate and panel computer.
The control section of the machine is comprised of automatic program control and manual control two cover systems.Automatic control system hardware comprises the touch screen panel computer, and special-purpose program controller detects and feedback element pressure transducer, temperature sensor, liquid level sensor and executive component bi-bit bi-pass low-temperature solenoid valve form.The manual control system of the machine is comprised of two manual modulation valves and Pressure gauge, and general is to make Emergency use under the burst power-off condition, and under the state, hand control valve is in closed condition usually.
The machine is used very easy, is summarized as follows:
Add liquid nitrogen: for the machine transport with the container of the liquid nitrogen of annotating be one identical with jar structure in the machine from the stainless cylinder of steel of supercharging.Only need the machine outer tank be linked to each other with machine inner canister filling opening with the dedicated transfusion flexible pipe when adding liquid nitrogen, open the hand-operated valve 38 on the machine inner canister exhaustor, closure plane outer tank air bleeding valve, open machine outer tank pressure charging valve, during standby outer tank Pressure gauge indicating value to 1.0～2.1Mpa, open fluid-delivery valve, liquid nitrogen just can the automatic press machine inner canister in.In the situation that the machine automatic control system is opened, the addition of liquid nitrogen dynamically shows with the percentage ratio form.Under off-position, the air vent that detects by an unaided eye has larger vaporific gas to overflow or represents that liquid nitrogen fills it up with when having liquid nitrogen to overflow.Close the outer tank fluid-delivery valve this moment, lays down the liquid feeding flexible pipe, closes the fridge manual exhaust valve, and it is for subsequent use that therapy apparatus can push operating room.
Energized at first when using in operating room is opened computer, and the main menu under the Windows environment appears in display screen; Then connect the refrigerator flexible pipe at machine liquid nitrogen delivery outlet, connect thermometric needle at the thermodetector interface; Press the computer interface prompting, after selection " automatically " program, machine just carries out supercharging, voltage stabilizing, liquid nitrogen output automatically according to preset program; This moment with refrigerator contact diseased region, thermometric needle places diseased region apart from refrigeration 5 millimeters places, computer namely begins timing, and the displaying time temperature curve.Machine is clicked " preservation data " after pressing auto-programming treatment end, and then data is stored in the machine hard disk.After clicking " end ", auto-programming stops operation.Machine is in service at auto-programming, can also carry out at any time manual intervention according to the treatment needs, revises the treatment parameter or repeats a certain step.
If select " manually " at computer interface after the start, the machine robot control system(RCS) then can not start, and each electromagnetic valve all is in closed condition voluntarily, can pass through the manual adjustment pressure charging valve, monitor controlled pressure with Pressure gauge, manual adjustments fluid-delivery valve control output liquid nitrogen flow is treated.Manually control just waits in emergency circumstances in the burst power failure and uses.
Described electromagnetic valve 33, hand-operated valve 1 and electromagnetic valve 26, hand-operated valve 27 are that electromagnetic valve and hand-operated valve are in parallel, are respectively applied to the valve sets of automatic and manual two cover control system.
