Problems solved by technology

However, the replacement needle of this device is equipped with dual channels, and the production process is still slightly complicated. Compared with the dispensing of some conventional cheap drugs, its production cost is still relatively high. The damage area is also relatively large when corking, which will have a certain impact on the integrity of the cork seal

Embodiment Construction

[0014] figure 1 Schematic diagram of the traditional dispensing method. The liquid preparation process needs to use syringe Z to draw a small amount of liquid from liquid bottle B and inject it into medicine bottle b to dissolve the medicine powder. After the medicine powder is dissolved, use syringe Z to draw back the solution from medicine bottle b and inject it into liquid bottle B. dispensing medicine. The whole process is not only complicated, but also the high-concentration powder injection solution will remain in the medicine bottle b and syringe Z, causing waste, and the needle of syringe Z is easily polluted by repeated exposure to the air.

[0015] figure 2 It is a structural schematic diagram of the dispensing device of the present invention. The dispensing device of the present invention is composed of a single-channel replacement needle 2, the replacement needle 2 is an integral structure, both ends are sharp, one end is inserted into the B end of the soft pla...

Abstract

The invention provides a simple single-passage dosage process and a dosage apparatus utilizing the same. A closed single passage is reserved between a medicine bottle and a soft plastic liquid bottle. The soft plastic liquid bottle is disposed above the medicine bottle reversely, drive force is generated by squeezing the soft plastic liquid bottle, and liquid in the soft plastic liquid bottle is squeezed into the medicine bottle to dissolve medicinal powder. The medicine bottle is then disposed above the soft plastic liquid bottle reversely, and air in the soft plastic liquid bottle is injected into the medicine bottle by squeezing the soft plastic liquid bottle again, so that liquid medicine in the medicine bottle is sucked into the soft plastic liquid bottle. Accordingly, the dosage process of transferring medical powder in the medicine bottle into the soft plastic liquid bottle is completed. The dosage apparatus consists of a single-passage displacement needle. Holes at two sharp ends of the displacement needle are communicated with each other to form a passage. By the aid of the simple single-passage dosage process and the dosage apparatus utilizing the same, operation can be simplified, pollution probability is lowered, medicine waste is reduced, cost is lowered, and high market popularization is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a simple single-channel dispensing method and a dispensing device. Background technique [0002] The dispensing method to the input liquid in existing medical treatment both at home and abroad, all is to adopt disposable syringe to suck a small amount of liquid to inject in the medicine bottle of dress powder injection, after the medicine powder fully dissolves, draw back with syringe again, inject in the liquid bottle. The above-mentioned traditional dispensing method has disadvantages such as drug waste, cumbersome process, and easy pollution. In view of the above deficiencies, the applicant once disclosed a dispensing method for powder injection and its dispensing device (application number: 201110231119.6, application date: August 12, 2011). The dispensing method using syringes is not suitable for glass or other types of liquid bottles, but the realizatio...
