Problems solved by technology

Although this structure solves the problem of the cotton swab storing the liquid medicine, when the end plug is opened for use, since the oil seal is located at the lower end of the liquid medicine, the oil seal will first contact the cotton head, and after the oil seal is completely wetted to the cotton head, the liquid medicine will On the one hand, the mixing of the oil seal and the liquid medicine will affect the use effect of the liquid medicine; on the other hand, it is necessary to solve the technical problem that the oil seal and the liquid medicine do not dissolve and interfere with each other when preparing the product

Embodiment 1

[0035] see figure 1As shown, the pneumatic liquid dropper of this embodiment includes a dropper body with a hollow cavity, and the upper end of the dropper body is connected to the upper end plug 1 through the upper connection point 2, and the upper end plug 1 seals the hollow cavity. The air inlet 8 formed at the top, the upper end plug can be formed by a broken line at the air inlet, the upper end of the broken line is the upper end cover, and the upper end cover can be broken along the broken line when in use, or the upper end The end cap is a sealing head that is sleeved outside the air inlet. When storing, the sealing head is placed at the air inlet to achieve sealing, and the sealing head can be pulled out during use, or the upper end cap is a sealing pin embedded in the air inlet. , insert the sealing pin into the air inlet to achieve sealing during storage, and pull out the sealing pin during use; the upper part of the hollow cavity in the dropper body is the liquid st...

Embodiment 2

[0043] see figure 2 As shown in the figure, the pneumatic liquid dropper of the present invention can be used as a portable medical sterilizing apparatus, and a plurality of pneumatic liquid droppers can also be equipped with different medicinal liquids (lubricant, disinfectant, sterilizing alcohol, iodine, bactericidal medicine). liquid, liquid medicine for the treatment of some specific skin diseases, etc.), and placed in the medical box by category for easy use.

[0044] When in use, first break the lower part of the dropper body with the sealed liquid column (that is, the lower broken end) through the lower broken part, and then open the upper end plug to connect the air inlet to the outside air. At this time, the broken part can be directly broken The liquid outlet formed later is placed above the part that needs to be coated with the liquid medicine, and the liquid medicine will be applied to the corresponding part.

Embodiment 3

[0046] see image 3 As shown, on the basis of Example 2, a dispersion for uniform coating and distribution of the medicinal liquid is provided in the isolation portion 4, and the part of the dispersion is located above the lower broken part 5, and after the lower broken end is broken, the dispersion is dispersed. A part of the body is exposed below the liquid outlet 9, and a part is located above the liquid outlet 9, which is convenient for the uniform coating of the liquid medicine. or see Figure 4 As shown, the dispersion is all located above the liquid outlet, and the lower end face of the dispersion is just flush with the liquid outlet or slightly higher than the liquid outlet.

Abstract

The invention discloses an air pressure liquid dropper and a manufacturing method thereof. The air pressure liquid dropper comprises a dropper body with a hollow cavity, the upper end of the dropper body is connected with an upper end plug (1) via an upper joint (2), an air inlet (8) formed at the top end of the hollow cavity is sealed by the upper end plug (1), a liquid storage portion (3) consisting of a liquid medicine column is arranged in the upper portion of the hollow cavity in the dropper body, the lower end of the liquid storage portion (3) is an isolating portion (4) consisting of an air column, and a liquid seal portion (6) consisting of a sealing liquid column is arranged at the lower end of the isolating portion (4). The air pressure liquid dropper can simultaneously resolve the problem that liquid medicine is mixed with sealing liquid and is polluted in storage and use processes. In addition, the manufacturing method is more convenient and brings convenience for industrial application and popularization.

Description

technical field [0001] The invention relates to a pneumatic liquid dropper and a preparation method thereof. Background technique [0002] In the prior art, it is necessary to apply liquid medicine (such as disinfectant water, disinfectant alcohol, medicinal liquid, etc.) and reagents to the local area. Usually, a cotton swab is needed for use, and the cotton swab is soaked in the liquid medicinal water. Then carry out the coating treatment. Since the cotton swab itself does not have a potion, it needs to be used in conjunction with the potion to function, which brings great inconvenience to the user. [0003] On this basis, the Chinese patent with the utility model patent number of 00249772.7 proposes an instant application cotton swab, which includes a cotton swab stick and a cotton tip fixed at one end of the cotton swab stick. One end of the hollow rod for fixing the cotton head is provided with an oil seal for sealing the medicinal solution, and the other end is provi...
