Description
Technical field:
This utility model belongs to medical instruments field, and concrete and a kind of liquid feeding air needle with release pressure is relevant.
Background technology:
In current medical procedure field, often need in airtight bottle, add liquid to carry out mixing or diluting, existing mode of operation adopts transfusion needle to insert liquid feeding in bottle, also to be inserted into air tube in bottle simultaneously, to maintain a bottle internal and external pressure balance, can not negative pressure be produced, work the mischief, this mode of operation, mode is loaded down with trivial details, operating difficulties and easily cause damage to bottle stopper.
Utility model content:
For the defect existed in prior art, this utility model provides a kind of structure simple, easy to operate a kind of liquid feeding air needle with release pressure.
For achieving the above object, technical solutions of the utility model are:
A kind of liquid feeding air needle with release pressure, comprise: holder 1, holder 1 is provided with mutual disconnected telescopic charging line 2 and breather line 3, puncturing head 4 is formed bottom charging line 2 and breather line 3, described charging line 2 is the internal layer of sleeve, top forms filling opening 2-1, bottom offers liquid outlet 2-2, described breather line 3 is the skin of sleeve, breather line 3 outer wall is provided with pore one 3-1 and pore two 3-2, when puncturing head 4 inserts in bottle, pore one 3-1 is positioned at bottle, and pore two 3-1 is positioned at outside bottle, thus release pressure of the inside of a bottle.
Further, described pore one 3-1 and pore two 3-2 lays respectively at the nearly bottom of breather line 3 and nearly apical position, is respectively two circular holes run through.
Further, described liquid outlet 2-2 is opened on charging line 2 lowermost end sidewall.
Adopt technique scheme, this utility model structure is simple, and easy and simple to handle, puncturing head only need insert in bottle and can operate by staff.
Accompanying drawing illustrates:
Fig. 1 is this utility model sectional structure chart;
Fig. 2 is this utility model three-dimensional structure diagram;
Fig. 3 is this utility model using state figure.
Detailed description of the invention:
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As shown in Figure 1-Figure 3, a kind of liquid feeding air needle with release pressure, comprise: holder 1, holder 1 is provided with mutual disconnected telescopic charging line 2 and breather line 3, puncturing head 4 is formed bottom charging line 2 and breather line 3, described charging line 2 is the internal layer of sleeve, top forms filling opening 2-1, bottom offers liquid outlet 2-2, described breather line 3 is the skin of sleeve, breather line 3 outer wall is provided with pore one 3-1 and pore two 3-2, when puncturing head 4 inserts in bottle, pore one 3-1 is positioned at bottle, pore two 3-1 is positioned at outside bottle, thus release pressure of the inside of a bottle.
In concrete implementation process, described pore one 3-1 and pore two 3-2 can be opened in respectively the nearly bottom of breather line 3 and nearly apical position, it is smooth and easy fully to ensure the air circulation inside and outside bottle to be respectively two circular holes run through, maintenance pressure balance.Described liquid outlet 2-2 can be opened on charging line 2 lowermost end sidewall and be added smoothly in bottle by liquid to facilitate.
During utility model works, after puncture needle thrusts bottle cap, liquid, inside bottle, is injected in bottle through charging line by filling opening by liquid outlet.Gas inside airtight bottle is communicated by pore one, breather line, pore two and external environment condition.Like this, when liquid feeding, the gas inside airtight bottle is compressed, and pressure increases, but gas is discharged into outside bottle by pore one, pore two through breather line, and the air pressure inside bottle is lowered.This device is made of one structure, easy to use.While liquid feeding in airtight bottle, the air pressure of release bottle interior, the harm that the increase of prevention bottle air pressure may cause.
This utility model structure is simple, and easy and simple to handle, puncturing head only need insert in bottle and can operate by staff.
Above-mentioned explanation illustrate and describes preferred embodiment of the present utility model, as previously mentioned, be to be understood that this utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of this utility model claims.
