Abstract
The utility model relates to an air inlet needle used for the air entering of a medical intravenous drip bottle, particularly a safe and clean air inlet needle which can avoid air from entering into an intravenous drip bottle through medical liquid in the intravenous drip bottle. The tail end of a hollow needle body is fixed in a hollow handle, and the length of the hollow needle body is greater than 170 mm. When the utility model is used, air is directly sent to the bottom of the intravenous drip bottle through the hollow part of the hollow handle the hollow part of the hollow needle body which is communicated with the hollow handle, but air does not pass the medical liquid in the intravenous drip bottle. The utility model can avoid the harmful substance in air from dissolving in the medical liquid and generating chemical reaction with the medical liquid, ensure personal safety and the cleanness of the medical liquid, and avoid the medical liquid from leaking from the air inlet needle when pressure in the intravenous drip bottle is larger.
Description
This utility model is the air inlet needle that is used for medical some drop bottle air inlet, particularly can avoid air to pass through the safely cleaning air inlet needle of the medicinal liquid inlet point drop bottle in the drop bottle.
When using the some drop bottle to have an intravenous drip, a kind of is to be inserted on the drop bottle cap with an injection syringe needle at present, and another kind is to tell an air inlet on the bottleneck plug of a drop bottle, and the two all is to rely on the negative pressure in the some drop bottle to send air in the some drop bottle.
Which kind of mode no matter is sent into air in the drop bottle and all is in the medicinal liquid from a drop bottle and passes, and in fact medicinal liquid has played the effect of filtered air.When have in the air harmful substances (as easily and the material of medicinal liquid generation chemical reaction etc.) during microgranule, these materials are easy to dissolve in medicinal liquid (or cause the variation of medicinal liquid chemical property with medicinal liquid generation chemical reaction) when sending into a drop bottle by medicinal liquid with air, inject human body then.When the drop pressure of the inside of a bottle was big, medicinal liquid also oozed out easily from air inlet syringe needle or air inlet simultaneously.
The purpose of this utility model is to design the safely cleaning air inlet needle that a kind of some drop bottle uses, and can directly send into a drop bottle to air and medicinal liquid in the drop bottle.
This utility model is fixed on the hollow needle body tail end of length greater than 170 millimeters in the hollow handle.In user mode, directly air is delivered to a drop bottle by the hollow of hollow handle and the hollow needle body that communicates with it hollow at the bottom of, and the medicinal liquid in the drop bottle.
The utlity model has following advantage:
1. can directly send into a drop bottle to air and medicinal liquid in the drop bottle, can avoid harmful substance in the air to dissolve in medicinal liquid or cause the variation of medicinal liquid chemical property, guarantee personal safety and medicinal liquid cleaning with medicinal liquid generation chemical reaction.
2. medicinal liquid oozes out from air inlet needle in the time of can avoiding the drop pressure of the inside of a bottle big.
3. can air filter be installed in hollow handle, make the air in the inlet point drop bottle be purified fully and filter.
Accompanying drawing 1 is the structural representation of this utility model embodiment.Omitted the interlude of hollow needle body among the figure.
The utility model will be further described below in conjunction with accompanying drawing.
(1). hollow needle body (2) front end is shaped on beveled point (1), the rear end is fixed in the hollow handle (5), hollow (3) of hollow needle body (2) communicate with hollow (6) of hollow handle (5), and the length of hollow needle body (2) is longer than 170 millimeters, external diameter greater than 1 millimeter.
(2). hollow handle (5) front end is shaped on conulite (4), and hollow needle body (2) rear portion is fixed in the conulite (4).
(3). in hollow (6) of hollow handle (5) filtering bodies (7) is housed.Filtering bodies (7) can be a filter membrane, also can be filtering agent.
Claims (5)
1. put drop bottle safely cleaning air inlet needle, it is characterized in that: hollow needle body (2) front end is shaped on beveled point (1), the rear end is fixed in the hollow handle (5), hollow (3) of hollow needle body (2) communicate with hollow (6) of hollow handle (5), and the length of hollow needle body (2) is longer than 170 millimeters, external diameter greater than 1 millimeter.
2. as claimed in claim 1 some drop bottle safely cleaning air inlet needle is characterized in that: hollow handle (5) front end is shaped on conulite (4), and hollow needle body (2) rear portion is fixed in the conulite (4).
