Problems solved by technology

[0005] 1. Inconvenient
The structures of injections, powder injections and injections / bags are different, and the opening methods are also different. Before configuration, they need to be opened separately and the medicines are prepared. During the operation, the medicine bottles are prone to dumping or confusion; 2. Inaccurate
During the dispensing process, the liquid needs to be quantitatively taken out from the injection bottle. However, the pressure in the medicine bottle is strong, and it is easy to leave a surplus when pulling the piston rod of the syringe, and when the dispensing volume is large, it is difficult to accurately control the amount drawn each time; 3. No Safety
During the preparation of the liquid medicine, it is necessary to pick up the injection bottle, powder bottle, and injection bottle one by one. There are many parts in contact with the hands, and there is a potential contamination of the liquid medicine; The incision is also easy to scratch the medical staff

Embodiment Construction

[0037] The dispensing station provided by the present invention is a brand-new device different from the traditional dispensing method. During the dispensing process, the device does not need to use a syringe to transfer the medicinal solution or draw the injection. During the use of traditional dispensing syringes, the cooperation of both hands is required, and a large extraction force is required, and the extraction direction is not fixed. In this scheme, the direction of extracting the medicinal liquid is limited to a straight line, so that the extraction of the medicinal liquid is more convenient and the controllability is good. The use of negative pressure devices to replace traditional manpower makes the dispensing process more labor-saving and accurate.

[0038] Comply with the above technical solutions, such as Figure 1 to Figure 10 As shown, the present invention provides a quantitative negative pressure liquid dispensing device, comprising a base 18, above the base...

Abstract

The invention discloses a quantitative negative-pressure liquid medicine dispensing device which comprises a bottom table. A slide rail which is perpendicular to the horizontal plane is arranged above the bottom table, a needle is movably assembled on the slide rail and is mounted on a medicine storage tube, and the medicine storage tube is connected with a negative-pressure device; a rotatable medicine dispensing disc is mounted on the bottom table, a plurality of insertion holes are circumferentially formed in the medicine dispensing disc, the centers of the insertion holes are positioned on the same circle, and projection of the needle on the medicine dispensing disc falls on the circle. The quantitative negative-pressure liquid medicine dispensing device has the advantages that the quantitative negative-pressure liquid medicine dispensing device which is a medicine dispensing appliance is a novel medicine dispensing tool and is safe, speedy and convenient in medicine dispensing procedures, and an effective auxiliary utensil can be provided for medical staffs.

Description

technical field [0001] The invention relates to a medical transfusion liquid configuration and transfer tool, in particular to a quantitative negative pressure liquid dispensing device, which can realize the configuration of the transfusion liquid accurately, conveniently and without pollution. Background technique [0002] The preparation of medicinal liquid is a basic work in ward nursing. With the rapid development of medical technology and the continuous increase of intravenous medication, standardization, safety and efficiency in the preparation of medicinal liquid are particularly important. [0003] For the configuration of general injections, commonly used drugs include sodium chloride injection, glucose injection, injection, powder injection, etc. When dispensing, it is necessary to take a part of the liquid medicine from the injection bag according to the actual injection dosage, and dissolve the injection and powder injection and add it to the injection. [0004]...
