SUMMERY OF THE UTILITY MODEL
In view of the above problem, the utility model provides a reduce extravagantly, improve burette cotton swab of cotton swab utilization ratio to guarantee to absorb more liquid medicines when dipping in same kind of liquid medicine, thereby can clean bigger wound area or increase and clean the number of times.
The technical scheme of the utility model is that: a dropper cotton swab comprises a circular empty groove at the top, a liquid storage pipe with a hollow middle part and a cotton head at the tail part, wherein the circular empty groove is connected with one end of the liquid storage pipe in a sealing mode, and the other end of the liquid storage pipe is wrapped by the cotton head.
The circular empty groove and the liquid storage pipe are made of PC materials.
And scale marks are arranged on the outer walls of the liquid storage pipe and the circular empty groove.
And the inner walls of the circular empty groove and the liquid storage pipe are coated with an anticorrosive plastic coating.
Both ends of the plastic hollow liquid storage pipe are provided with open holes.
The utility model has the advantages that: because the utility model discloses the middle part is equipped with the liquid storage pipe, can once absorb the liquid medicine of capacity, avoids liquid medicine not enough to need dip in many times and get to avoid not using liquid medicine in the medicine bottle to be polluted. And the waste caused by using a plurality of cotton swabs at one time is also avoided.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the following will further describe the present invention; obviously, the following description is only a part of the embodiments, and it is obvious for a person skilled in the art to apply the technical solution of the present invention to other similar situations without creative efforts; in order to more clearly illustrate the technical solution of the present invention, the following detailed description is made with reference to the accompanying drawings:
as shown in the figure; a dropper cotton swab comprises a circular empty groove 3 at the top, a liquid storage pipe 2 with a hollow middle part and a cotton head 1 at the tail part, wherein the circular empty groove 3 is hermetically connected with one end of the liquid storage pipe 2, and the other end of the liquid storage pipe 2 is wrapped by the cotton head 1; the three parts are normally fixedly and hermetically connected, so that the leakage of the liquid medicine can be prevented.
The circular empty groove 3 and the liquid storage pipe 2 are made of PC materials, and the circular empty groove 3 and the liquid storage pipe 2 are made of plastic materials under normal conditions.
And scale marks are arranged on the outer walls of the liquid storage pipe 2 and the circular empty groove 3 and are used for displaying the amount of the liquid medicine in the liquid storage pipe 2 and the circular empty groove 3.
The inner walls of the circular empty groove 3 and the liquid storage pipe 2 are coated with anti-corrosion plastic coating layers, and some liquid medicines have a corrosion function, so that the circular empty groove 3 and the liquid storage pipe 2 can be prevented from being damaged.
Both ends of the plastic hollow liquid storage pipe 2 are provided with open holes; this facilitates the entry and exit of the liquid medicine.
The utility model discloses a theory of operation:
(1) firstly, a circular empty groove 3 at the upper part of a dropper cotton swab is squeezed by hands, and a part of air in the dropper cotton swab is discharged;
(2) continuously pinching a round empty groove 3 at the upper part of the dropper cotton swab, and fully soaking the cotton head 1 of the cotton swab in the liquid medicine;
(3) the hand is loosened, the air pressure in the dropper cotton swab is smaller than the external atmospheric pressure, and the liquid medicine is pushed to enter the liquid storage pipe 2 in the dropper cotton swab;
(4) after the liquid medicine is sucked, the liquid medicine page of the liquid storage pipe 2 in the dropper cotton swab is stable, and the dropper cotton swab is taken out and placed at a place needing to be smeared;
(5) when the amount of liquid medicine in the cotton head 1 of the dropper cotton swab is reduced and the dropper cotton swab is not enough to be used, the circular empty groove 3 in the upper portion of the dropper cotton swab is squeezed, and the liquid medicine enters the cotton head 1 from the liquid storage pipe 2;
(6) and the cotton swab is continuously used until the cotton swab is not needed to be used or the liquid medicine in the liquid storage pipe 2 is used up, and the dropper cotton swab is discarded.
Finally, it should be understood that the embodiments described herein are merely illustrative of the principles of embodiments of the present invention; other variations are also possible within the scope of the invention; thus, by way of example, and not limitation, alternative configurations of embodiments of the present invention may be considered consistent with the teachings of the present invention; accordingly, embodiments of the present invention are not limited to the embodiments specifically described and illustrated herein.
