Abstract
The utility model discloses a portable liquid nitrogen cryoprobe comprising a liquid nitrogen reservoir, wherein the front end of the liquid nitrogen reservoir is provided with a cryopencil holder; the cryopencil holder is connected with a timer and a pressure indicator; the front part of the cryopencil holder is sleeved with a cryopencil; a cryopencil core is arranged at the front end inside the cryopencil; the rear end of the cryopencil is connected with a contact head of the timer and the contact head of the pressure indicator; a cryopencil cover is sleeved outside the cryopencil holder; and the rear end of the liquid nitrogen reservoir is provided with a liquid nitrogen push rod. By using the portable liquid nitrogen cryoprobe, the cryogenic time, the pressure and the cryogenic area of liquid nitrogen can be scientifically controlled, so that the treatment is more reasonable, and reliable treating parameters can be provided for doctors. Instruments for reserving liquid nitrogen for liquid nitrogen cryogenic therapeutics at present and instruments used during treatment are greatly improved, so that treatment operation and reservation are more convenient and reliable and safer. The liquid nitrogen cryoprobe is designed to be portable so that the possibility for a patient to take with the liquid nitrogen cryoprobe for subsequent self-treatment is achieved.
Description
Technical field
This utility model relates to need carry out the dermopathic medical apparatus and instruments of liquid nitrogen cryotherapy, is a kind of portable liquid chilled nitrogen device specifically.
Background technology
For suffering from dermopathic patient, need to adopt the liquid nitrogen freezing technology to treat in many cases.Present treatment present situation is: the doctor is according to the size of ill area on the patient skin, use pocket knife sharpening cotton swab head, and then volume is gone up absorbent cotton, make the cotton swab head size corresponding with skin site of disease size, dipping in liquid nitrogen liquid then carries out freezing, its refrigerated time and pressure are controlled by doctor's treatment experience entirely, thereby the effect of each treatment depends on whether the experience of implementing the treatment doctor is abundant more.
The utility model content
Technical problem to be solved in the utility model is to overcome at present in the liquid nitrogen cryotherapy process that liquid nitrogen is volatile, rule of thumb, operating data such as can not quantize at problem when carrying inconvenience, operation, the dermopathic portable liquid chilled nitrogen of a kind of treatment device is provided, is mainly used in the dermatosis that is suitable for liquid nitrogen cryotherapy.
This utility model adopts following technical proposals to solve its technical problem:
A kind of portable liquid chilled nitrogen device, comprise liquid nitrogen container, the liquid nitrogen container front end is established a freezing headstock, be connected with timer and pressure indicator on the freezing headstock, the anterior suit one freezing head of freezing headstock, freezing Inner Front End established one freezing core, and freezing rear end joins with timer contact, pressure indicator contact, the outside suit one freezing skull of described freezing headstock, described liquid nitrogen container rear end is provided with the liquid nitrogen push rod.
Described freezing head is provided with 1mm
2, 2mm
2, 3mm
2, 5mm
2, 7mm
2And 9mm
2Different size.
Described freezing core is disposable freezing core.
Adorn a spring between described freezing headstock and the freezing head.
The liquid nitrogen cryotherapy dermatosis method that this utility model makes present use is pushed forward by by rule of thumb manual therapeutic method only, time, pressure and the freezing area of control liquid nitrogen freezing that can science, make treatment more reasonable, can provide reliable treatment parameter for the doctor.The treatment experience of doctor's success can be quantized with scientific methods, and concrete parameter is shown, make therapeutic scheme science and reasonable more.The equipment that it will make the equipment of the employed storage liquid nitrogen of present liquid nitrogen cryotherapy art and when treatment use is greatly improved, and makes treatment operation, keeping more convenient, safe, reliably.Liquid nitrogen cryotherapy often need repeatedly be treated, and for solving the problem that nonlocal patient treatment interrupts, this utility model is designed to portable, and the patient can being carried and carry out follow-up Heal Thyself becomes possibility.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
This utility model provides a kind of portable liquid chilled nitrogen device, comprise liquid nitrogen container 10, liquid nitrogen container 10 front ends connect a freezing headstock 1, be connected with timer 8 and pressure indicator 9 on the freezing headstock 1, one freezing 4 of freezing headstock 1 anterior suit is adorned a spring 2 between freezing headstock 1 and freezing 4.Freezing 4 Inner Front End adorned one freezing core 5, and freezing 4 rear end joins with timer contact 6, pressure indicator contact 7.Be provided with 1mm for freezing 4
2, 2mm
2, 3mm
2, 5mm
2, 7mm
2And 9mm
2Different size.Freezing headstock 1 outside suit one freezing skull 3.Liquid nitrogen container 10 rear ends are provided with liquid nitrogen push rod 11.For avoiding disease to infect mutually, freezing core 5 can adopt disposable freezing core.Not reproducible use.
Design has timer to require the control cooling time according to treatment on the cryoprobe of the present utility model.The freezing pressure that when the pressure indicator may command is freezing the affected part is applied, thus refrigerating process institute operation parameter can effectively be controlled, guarantee that therapeutic effect is safe and reliable.Reservoir is made by the heat-barrier material evacuation, guarantees the liquid nitrogen volatilization less and slowly, do not reveal, and the liquid nitrogen perfusion is easy to use.
Concrete operations are as follows:
1. at first by the doctor patient diagnosed state of an illness, select the liquid nitrogen freezing head of corresponding specification for use according to the state of an illness.
2. set cooling time and pressure parameter required when treating.
3. check that whether the liquid nitrogen freezing device is intact, installs selected liquid nitrogen freezing head assembly.
4. aim at patient's disease sites, carry out cold therapy by the freezing parameter that the doctor determines.
5. treatment finishes, and the liquid nitrogen freezing device is restored to the original state, and take out used freezing core, and it is abandoned, and after freezing disinfection, loads onto freezing new core again, places standby.
