Abstract
A double-cap liquid nitrogen tank belongs to the field of medical appliances and solves the problem that liquid nitrogen is wasted due to the fact that liquid nitrogen tanks are not easy to be closed in time by medical staff during cryotherapy. The double-cap liquid nitrogen tank comprises a tank body (1), an outer cap (2), a liquid nitrogen spoon (5) and an inner cap (3). A spigot is arranged on the inner wall of a mouth of the tank body (1), the peripheral edge of the inner cap (3) is fastened onto the spigot on the inner wall of the mouth of the tank body (1), and a handle (4) of the liquid nitrogen spoon (5) is fixed with the inner cap (3) after penetrating through the same. The double-cap liquid nitrogen tank has the advantages of convenience in use, excellent tightness and capability of avoiding volatilization and waste of liquid nitrogen.
Description
Technical field
This utility model belongs to field of medical products, is specifically related to a kind of device that is used for cold therapy.
Background technology
Cold therapy be a kind of utilization to local tissue freezing, controllably destroy or excise living tissue Therapeutic Method, be department of dermatologry therapy comparatively commonly used.The most frequently used cryogen of cold therapy is a liquid nitrogen, and liquid nitrogen answers sealed storage to prevent its volatilization.But; Medical personnel at first will open the lid of liquid nitrogen container when the patient is carried out cold therapy, get some liquid nitrogen through getting nitrogen spoon Sheng then; After picking liquid nitrogen with cotton swab etc.; Need promptly patient's affected part to be handled, then will get the nitrogen spoon again and put back in the liquid nitrogen container, build the lid of liquid nitrogen container at last.Owing to can not in time the lid of liquid nitrogen container be built, this will cause the volatilization and the waste of liquid nitrogen.
Summary of the invention
The purpose of this utility model is in the process of carrying out cold therapy, to be difficult in time building liquid nitrogen container and wasting problem in order to solve medical personnel, and a kind of double-canopy formula liquid nitrogen container is provided.
This double-canopy formula liquid nitrogen container comprises tank body, enclosing cover, gets the nitrogen spoon, also comprises inner cap, and the jar mouthful inwall of said tank body is provided with seam, and the card of inner cap is on the seam of jar mouth inwall; The said kettleholder of getting the nitrogen spoon passes inner cap and fixes with inner cap.
The sidewall of said inner cap contacts with jar inwall of mouth.
The utlity model has following beneficial effect:
The inner cap of this double-canopy formula liquid nitrogen container with get the nitrogen spoon and fix, when medical personnel need get nitrogen, open enclosing cover earlier, will get the nitrogen spoon through kettleholder then and upwards mention, this moment, inner cap also can be along with kettleholder be upwards mentioned, liquid nitrogen container is opened simultaneously; When medical personnel dip in when having got liquid nitrogen and will get the nitrogen spoon and be put back in the liquid nitrogen container, inner cap just can be presented to simultaneously in the jar mouthful of liquid nitrogen container and the liquid nitrogen cover is tight.Owing to take out and get the nitrogen spoon and open inner cap and put back to get the nitrogen spoon and build inner cap and all carry out synchronously; Medical personnel need not to operate respectively; Therefore effectively avoided medical personnel in giving the patient treatment process; To give patient treatment rapidly after having got liquid nitrogen dipping in, thereby often can not build cover immediately and cause the problem of liquid nitrogen volatilization waste.Simultaneously, the double-deck cover design of enclosing cover and inner cap can guarantee effectively that liquid nitrogen container has excellent sealing performance in daily storage process.
The utlity model has easy to use, good seal performance and can effectively avoid the advantage of liquid nitrogen volatilization waste.
Description of drawings
Fig. 1 is the combination sketch map of this utility model.
1-tank body; 2-enclosing cover; 3-inner cap; 4-kettleholder; 5-get the nitrogen spoon.
The specific embodiment
Below in conjunction with Fig. 1 this utility model is further specified:
This double-canopy formula liquid nitrogen container comprises tank body 1, enclosing cover 2 and gets nitrogen spoon 5, has on the jar of tank body 1 mouthful to make the kettleholder 4 of getting nitrogen spoon 5 reach a jar outer groove, and groove can be carried out encapsulation process.Also comprise inner cap 3, the jar mouthful inwall of said tank body 1 is provided with seam, and the card of inner cap 3 is on the seam of jar mouth inwall; Adopt said structure; Inner cap 3 can increase the sealing property of liquid nitrogen container, and the seam of inwall can be circumferential, and seam can prevent effectively that inner cap 3 from dropping in the liquid nitrogen container; Inner cap 3 lower surfaces become circumferential contact with seam simultaneously, can effectively play sealing function.Inner cap 3 can adopt to have certain elastic Quercus acutissima Carr. and processes; The sidewall of inner cap 3 can contact with the inwall of jar mouth; Adopt said structure, the sidewall of inner cap 3 closely contacts with can making between the two after jar inwall of mouth contacts, thereby further strengthens the sealing property of inner cap 3.The said kettleholder 4 of getting nitrogen spoon 5 passes inner cap 3 and fixes with inner cap 3, adopts said structure, when medical personnel need get nitrogen; Open enclosing cover 1 earlier; To get nitrogen spoon 5 through kettleholder 4 then and upwards mention, this moment, inner cap 3 also can be along with kettleholder 4 be upwards mentioned, and liquid nitrogen container is opened simultaneously; When medical personnel dip in when having got liquid nitrogen and will get nitrogen spoon 5 and be put back in the liquid nitrogen container, inner cap 3 just can be presented to simultaneously in the jar mouthful of liquid nitrogen container and the liquid nitrogen cover is tight.Owing to take out and get nitrogen spoon 5 and get nitrogen spoon 5 and build inner cap 3 and all carry out synchronously with opening inner cap 3 and put back to; Medical personnel need not to operate respectively; Not free poor; Therefore effectively avoided medical personnel in giving the patient treatment process, will give patient treatment rapidly after having got liquid nitrogen dipping in, thereby often can not build cover immediately and cause the problem that liquid nitrogen volatilizees to be wasted.This double-canopy formula liquid nitrogen container adopts the enclosing cover 1 and the double-deck cover of inner cap 3 to design, and builds enclosing cover 1 once medical personnel forget, only can effectively guarantee the sealing property of liquid nitrogen container through inner cap 3; Simultaneously, double-canopy formula design can guarantee effectively that also liquid nitrogen container has excellent sealing performance in daily storage process.
The utlity model has easy to use, good seal performance and can effectively avoid the advantage of liquid nitrogen volatilization waste.
