Abstract
The utility model relates to a kind of rubber head droppers, including ontology and extension pipe, the ontology is made of Capsule and glass pipette, it is equipped with Capsule in the upper end of glass pipette, the lower end of glass pipette is back taper, and the glass pipette is made of neck, liquid storing part and drawing section, liquid storing part is spherical shape, internal diameter is greater than the outer diameter of neck and drawing section, is equipped with external screw thread in the lower part of drawing section, is closely connect by the external screw thread of drawing section with extension pipe.The beneficial effects of the utility model are: reasonable in design, uptake is big, and cleaning is easy, and high-efficient, use scope is wide, can prevent medical fluid from entering Capsule, and long service life can lengthen the length of rubber head dropper, easy to use.
Description
Technical field:
The utility model relates to a kind of rubber head droppers, belong to teaching experiment equipment technical field.
Background technique:
Rubber head dropper is also known as Capsule dropper, it is a kind of instrument for drawing or being added dropwise a small amount of liquid reagent.In school
Laboratory carries out various teaching experiments and commonly uses rubber head dropper absorption medical fluid often, and traditional rubber head dropper is inhaled by Capsule and glass
Pipe composition, when using rubber head dropper liquid feeding, cannot protrude into container, can not contact container.Due to the volume of glass pipette inner cavity
Small, the medical fluid once drawn is few, is also easy to that there is a phenomenon where medical fluids to enter Capsule.After rubber head dropper is finished, water is used immediately
It cleans, due to the aperture very little of rubber head dropper lower end, cleaning is difficult.It could be drawn after being finished, after being eluted with water immediately another
One reagent, service efficiency are low.Due to the length of traditional rubber head dropper be it is fixed, after the decline of medical fluid face, former rubber head is dripped
When pipe is drawn less than medical fluid, it is necessary to longer rubber head dropper is replaced, it is inconvenient to use, therefore, it is necessary to rubber head dropper
Structure improves.
Summary of the invention:
The purpose of this utility model is the deficiency for existing rubber head dropper, provides that a kind of uptake is big, and cleaning is easy, energy
It prevents medical fluid from entering Capsule, the length of rubber head dropper, rubber head dropper easy to use can be lengthened.
To achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of rubber head dropper, including ontology and extension pipe, the ontology is made of Capsule and glass pipette, in glass pipette
Upper end be equipped with Capsule, the lower end of glass pipette is back taper, convenient for drawing medical fluid.The glass pipette is by neck, liquid storing part
It is formed with drawing section, liquid storing part is spherical shape, and internal diameter is greater than the outer diameter of neck and drawing section, can store more medical fluid, prevent medical fluid
Into Capsule.It is equipped with external screw thread in the lower part of drawing section, can closely be connect, can be lengthened with extension pipe by the external screw thread of drawing section
The length of rubber head dropper draws the medical fluid of higher depth.
The lower end of the extension pipe is back taper, and the inner surface on extension pipe top is equipped with internal screw thread, is inhaled convenient for connection glass
The drawing section of pipe.
The quantity of the extension pipe is n, n >=1.
The beneficial effects of the utility model are: reasonable in design, uptake is big, and cleaning is easy, high-efficient, use scope
Extensively, it can prevent medical fluid from entering Capsule, long service life can lengthen the length of rubber head dropper, easy to use.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of ontology in the utility model.
Fig. 3 is the structural schematic diagram of extension pipe in the utility model.
In figure: 1 Capsule, 2 necks, 3 liquid storing parts, 4 drawing sections, 5 extension pipes.
Specific embodiment:
As shown in Figure 1-3, a kind of rubber head dropper, including ontology and extension pipe (5), the quantity of the extension pipe (5) they are n
It is a, n >=1.The ontology is made of Capsule (1) and glass pipette, is equipped with Capsule (1) in the upper end of glass pipette, glass pipette
Lower end be back taper, convenient for draw medical fluid.The glass pipette is made of neck (2), liquid storing part (3) and drawing section (4), storage
Liquid portion (3) is spherical shape, and internal diameter is greater than the outer diameter of neck (2) and drawing section (4), can store more medical fluid, prevent medical fluid from entering glue
Cap (1).It is equipped with external screw thread in the lower part of drawing section (4), can closely be connect by the external screw thread of drawing section (4) with extension pipe (5),
The length that rubber head dropper can be lengthened draws the medical fluid of higher depth.The lower end of the extension pipe (5) is back taper, on extension pipe (5)
The inner surface in portion is equipped with internal screw thread, convenient for connecting the drawing section (4) of glass pipette.
Operation principle and using method: when liquid level is higher, absorption medical fluid, medical fluid edge are carried out using the ontology of rubber head dropper
The drawing section (4) of glass pipette rises, and when medical fluid rises to liquid storing part (3), since the inner cavity of liquid storing part (3) is larger, exceeds
The liquid medicine storage of drawing section (4) prevents medical fluid from entering Capsule (1) in liquid storing part (3).When liquid level is lower, dripped using rubber head
The ontology of pipe can not draw medical fluid, can be connected at this time by the external screw thread of drawing section (4) with extension pipe (5), can lengthen glue
The length of head dropper, draws the medical fluid of higher depth.When needing to draw another medical fluid, first extension pipe (5) is removed, is changed new
Extension pipe (5) can draw another medical fluid, the lower part of the liquid medicine storage of absorption in extension pipe (5).Medical fluid Shi Weifang is added dropwise
Only medical fluid splashes out, and liquid level can be protruded into the lower end of extension pipe (5) hereinafter, removing extension pipe (5) after, will not influence glue
The ontology of head dropper.It needs to be cleaned in time after extension pipe (5) use, due to suitable for reading larger, the cleaning appearance of extension pipe (5)
Easily.
