Description
Technical field
The present invention relates to a kind of dropper, relate in particular to a kind of detachable dropper, belong to medical equipment technical field.
Background technology
In medical equipment technical field, conventional small appliance has multiple, and dropper is wherein a kind of just.Dropper is generally used for drawing or adding a small amount of reagent, and draws supernatant liquor, isolates precipitation etc.Traditional dropper comprises press head and straight tube, and press head is fixed in straight tube one end, and the other end is provided with suction inlet, when use, utilize dropper perpendicular to directly over container, clutch press head with finger, make press head distortion that air is wherein discharged from straight tube, then dropper is put into solution, decontrol finger, press head recovers suction inlet draw solution simultaneously, and solution drawn in suction pipe like this, and such dropper is simple in structure, low cost of manufacture is used widely in medical procedure.But, also there is certain problem in such dropper, because press head is to be usually fixedly connected with straight tube, in the time of draw solution, press the dynamics of press head excessive if pinch, can make the solution in straight tube too much enter press head, or solution flows backwards in the time keeping flat or be inverted, and corrosion press head, long-term corrosion easily causes press head to damage, and can not change, cause whole dropper not re-use, shorten service life, reduced the practicality of dropper, therefore made dropper in use have limitation.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, the dropper providing, form demountable structure by press head and straight tube, in the time that press head is corroded, be convenient for changing, whole dropper can be reused, simple to operate, extend its service life, and further improve corrosion resistance by corrosion-resistant coating again, improved on the whole the practicality of dropper, it can be used more easily.
The present invention specifically solves the problems of the technologies described above by the following technical solutions:
A kind of detachable dropper, comprises with the straight tube of suction inlet and is positioned at the press head of straight tube one end, on the gas outlet place of described press head and the outer wall of straight tube one end, be equipped with screw thread, described straight tube one end is fixedly connected with press head by screw thread.
As a preferred technical solution of the present invention: described press head is that air bag and the press head inwall that flexible plastic is made is provided with corrosion-resistant coating.
As a preferred technical solution of the present invention: described press head is that the outer wall of cylinder and press head is provided with scale.
As a preferred technical solution of the present invention: described suction inlet is flat.
As a preferred technical solution of the present invention: the outer wall of described straight tube is provided with graduation mark.
The present invention adopts technique scheme, can produce following technique effect:
Dropper provided by the invention, forms demountable structure by press head and straight tube, in the time that press head is corroded, is convenient for changing, and whole dropper can be reused, simple to operate, has extended its service life.In addition, press head is that air bag and the press head inwall that flexible plastic is made is provided with corrosion-resistant coating, the hardness that improves press head by plastic material can guarantee again certain pliability, conveniently pinching pressure can avoid again traditional quality of rubber materials excessively soft, and by the corrosion-resistant coating of inwall, further improve the corrosion resistance of press head, extend the service life of press head.Press head is that the outer wall of cylinder and press head is provided with scale, utilize after this structure, when can making in time in draw solution or keeping flat, be inverted, solution can flow into press head, and can be stored in cylindrical press head, is provided with scale by cylindrical surface, can directly observe the capacity of solution, can avoid corrosion, can realize again storage, thereby strengthen the service efficiency of dropper.Suction inlet is flat, can replace traditional circular suction inlet, facilitates dropper to utilize flat structure and solution laminating, and solution is more easily drawn.The outer wall of straight tube is provided with graduation mark, can be in the time of inhalation solution, i.e. and observable capacity.Therefore, the present invention, by the whole dropper being made improvements, can change the press head of dropper, and dropper is reused, and further improves corrosion resistance, has improved the practicality of dropper, and it can be used more easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of dropper of the present invention.
Wherein label is explained: 1-straight tube, 2-press head, 3-suction inlet, 4-screw thread, 5-graduation mark.
The specific embodiment
as shown in Figure 1, the present invention has designed a kind of detachable dropper, comprise with the straight tube 1 of suction inlet 3 and be positioned at the press head 2 of straight tube 1 one end, on the outer wall of the gas outlet place of described press head 2 and straight tube 1 one end, be equipped with screw thread 4, described straight tube 1 one end is fixedly connected with press head 2 by screw thread 4.
In addition, the flexible plastic of air bag can make for to(for) press head 2, and press head 2 inwalls are provided with corrosion-resistant coating, the hardness that improves press head by plastic material can guarantee again certain pliability, conveniently pinching pressure can avoid again traditional quality of rubber materials excessively soft, and by the corrosion-resistant coating of inwall, further improve the corrosion resistance of press head, extend the service life of press head.
If the outer wall that press head 2 is cylinder and press head 2 is provided with scale, when can making in time in draw solution or keeping flat, be inverted, solution can flow into press head, and can be stored in cylindrical press head, be provided with scale by cylindrical surface, can directly observe the capacity of solution, can avoid corrosion, can realize again storage.
Can be flat for suction inlet 3, replace traditional circular suction inlet, facilitate dropper to utilize flat structure and solution laminating, solution is more easily drawn.The outer wall of straight tube 1 is provided with graduation mark 5, can be in the time of inhalation solution, i.e. and observable capacity.
One embodiment of the invention are structure as shown in Figure 1, builds dropper by foregoing description, is provided with graduation mark 5 on straight tube 1, and suction inlet 3 is flat, press head 2 is for being with graduated cylinder, and cylinder inwall has corrosion-resistant coating, and fixes by one end of spiral way and straight tube 1.In use, first clutch press head 2, make wherein Bas Discharged, recycling suction inlet 3 is aimed at solution solution is sucked from straight tube 1, need to store time, repeatedly pinch press or disposable pinch to press after making that solution is a large amount of and sucking deposit in the press head 2 with corrosion-resistant coating, in this process, can utilize the graduation mark 5 on straight tube 1 to carry out observation capacity.In the time that needs are discharged solution, then pinch and press press head 2, solution is discharged along straight tube 1.After long-term use, can change press head 2, back out the one end by it from straight tube 1, replaces with new press head 2, after formation sealing, can reuse, and dropper can be changed.
Therefore, the present invention, by the whole dropper being made improvements, can change the press head of dropper, and dropper is reused, and further improves corrosion resistance, has improved the practicality of dropper, and it can be used more easily.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes a variety of changes.
