Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of portable liquid chilled nitrogen device.
Background technology
Liquid nitrogen cryotherapy is a new technique in therapeutics in modern age field.Liquid nitrogen cryotherapy is a kind of comprehensive effect of cryobiology.Under extremely freezing state, can there is irreversible infringement in normal cell.It is exactly by under extremely freezing state, and lesion cell is killed rapidly, and lesion is recovered normally.Generally be used for treating verruca vulgaris, clavus, wart, neurodermatitis and dermatosis etc.The position that can help the shallow-layer of hemostasis and removal skin surface to cut off by quick-frozen method in surgical operation, as burn, blood stasis.In gynecological, be also widely used, as: cervicitis, external genital tumor etc.
The boiling point of nitrogen is-196 DEG C, will form liquid nitrogen if depress temperature at normal atmosphere below this; If pressurization can obtain liquid nitrogen at higher temperature.In Hospitals at Present, conventional liquid nitrogen freezing device is liquid nitrogen cryotherapy instrument, it is made up of cold head, drain pipe, liquid nitrogen cup, handle four parts, the pressure that relies on liquid nitrogen vaporization to form, makes liquid nitrogen flow into cold head from liquid nitrogen cup by drain pipe, thereby reaches the effect of cold therapy.But this liquid nitrogen cryotherapy instrument weight is large, cost is higher, on the one hand, when use, transferring to another ward from a ward wastes time and energy, and has virtually improved on the other hand patient's medical expense.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of portable liquid chilled nitrogen instrument, have advantages of easy to use, cost is low, meets patient's needs.
For addressing the above problem, the technical scheme that this utility model adopts is as follows:
A kind of portable liquid chilled nitrogen device, it comprises freezing cup, liquid nitrogen shower nozzle, described shower nozzle comprises the drain pipe of cup plug, air inlet pipe and output liquid nitrogen for sealing freezing cup; Described cup plug, for resilient plug, is provided with along its circumferencial direction the groove circle that supreme twice are parallel to each other on the cock body of resilient plug; One end of described air inlet pipe enters freezing cup inside through cup, is provided with controls the control piece that air enters in one end of air inlet pipe; Described drain pipe is broken pipe, and one end of broken pipe is enclosed within air inlet pipe and is deep into the not bottom of contact refrigeration cup of freezing bottom of cup, its other end be positioned at cup beyond the Great Wall the body of the air inlet pipe of side pass outside air inlet pipe.
This utility model can be realized by following scheme:
As a kind of preferred scheme of this utility model, described air inlet pipe and drain pipe are metal tube.
As a kind of preferred scheme of this utility model, described control piece is a flexible pipe, and one end of flexible pipe is connected on metal tube, and its other end is free end.
As a kind of preferred scheme of this utility model, described control piece comprises an air bag, and described air bag is compressible plastic utricule, is provided with air inlet on air bag, between air bag and air inlet pipe, is provided with intake valve.
As a kind of preferred scheme of this utility model, the diameter of described drain pipe is no more than 2mm.
As a kind of preferred scheme of this utility model, the length that described air inlet pipe extend in freezing cup is no more than 3cm.
As a kind of preferred scheme of this utility model, the diameter of described air inlet pipe is 2-3 times of drain pipe diameter.
Compared to existing technology, the beneficial effects of the utility model are:
The simple volume of portable liquid chilled nitrogen apparatus structure described in the utility model little, be convenient for carrying; Especially in the time using to sufferer, medical personnel's one man operation separately, very convenient;
2. portable liquid chilled nitrogen device described in the utility model is made simply, can make full use of existing resource, cuts the waste, and reduces costs, and saves patient's medical expense;
Portable liquid chilled nitrogen device described in the utility model further by the diameter control of drain pipe below 2mm, can effectively control the spray volume of liquid nitrogen, prevent the injury of liquid nitrogen to human body, improve security performance.
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Wherein, 1 is freezing cup, and 2 is cup plug, and 3 is air inlet pipe, and 4 is control piece, and 5 is drain pipe, and 6 is intake valve.
Detailed description of the invention
As shown in Figure 1 and Figure 2, portable liquid chilled nitrogen device described in the utility model, it comprises freezing cup 1, liquid nitrogen shower nozzle, described liquid nitrogen shower nozzle comprises the drain pipe 5 of cup plug 2, air inlet pipe 3 and output liquid nitrogen for sealing freezing cup 1; Described cup plug 2 is resilient plug, on the cock body of resilient plug, is provided with along its circumferencial direction the groove circle 21 that supreme twice are parallel to each other; One end of described air inlet pipe 3 enters into freezing cup 1 inside through cup plug 2, is provided with controls the control piece 4 that air enters in one end of air inlet pipe 3; Described drain pipe 5 is broken pipe, and one end of broken pipe is enclosed within air inlet pipe 3 and is deep into the not bottom of contact refrigeration cup 1, freezing cup 1 bottom, and the body of the air inlet pipe 3 of its other end above being positioned at cup plug 2 pierces into outside trachea 3.
This utility model can be realized by following scheme:
In this utility model, the material of air inlet pipe and drain pipe can not limit, but in order to sterilize, meet hygienic requirements, preferred, described air inlet pipe and drain pipe are metal tube.Specifically can adopt ferrum, copper, aluminum, rustless steel etc. not to limit, but preferably select rustless steel, not react with nitrogen.
As shown in Figure 1, in one embodiment of the invention, described control piece is a flexible pipe, and one end of flexible pipe is connected on metal tube, and its other end is free end.Medical personnel can be directly by squeezing tube with unclamp flexible pipe and realize and emit a small amount of liquid nitrogen cold therapy is carried out in affected part.
Consider in the time that the liquid nitrogen in freezing cup remains small amount, liquid nitrogen to be extruded from drain pipe, need larger pressure, also just mean that needs pour into a large amount of air in freezing cup, therefore, as shown in Figure 2, as preferably, in another embodiment of the present invention, described control piece comprises an air bag, described air bag is compressible plastic utricule, is provided with air inlet on air bag, is provided with intake valve 6 between air bag and air inlet pipe.By to airbag aeration, then extruding gasbag, even a remaining little liquid nitrogen also can fully be extruded in bottle.
On the basis of above-described embodiment, as preferably, the diameter of described drain pipe is no more than 2mm.The diameter of drain pipe is less, can effectively control the spray volume of liquid nitrogen, prevents the injury of liquid nitrogen to human body, improves security performance.
As a kind of preferred scheme of this utility model, the length that described air inlet pipe extend in freezing cup is no more than 3cm.
Because liquid nitrogen will be extruded from drain pipe, need enough pressure, therefore poor for equalizing pressure, liquid nitrogen can be easily extruded, in this utility model, the diameter of described air inlet pipe is 2-3 times of drain pipe diameter.
Above-mentioned embodiment is only preferred implementation of the present utility model; the scope that can not limit with this this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to this utility model scope required for protection.
