Soft infusion bag manual filling equipment and method for filling soft infusion bags by using same

Abstract

The invention discloses soft infusion bag manual filling equipment and a method for filling soft infusion bags by using the same. The equipment comprises a liquid supply device, wherein liquid discharging nozzles are arranged on the liquid supply device; a valve is arranged on each liquid discharging nozzle; the liquid supply device comprises a liquid feeding pipeline and at least two liquid discharging branches which are communicated with the liquid feeding pipeline; a flow meter is arranged between each liquid discharging branch and the liquid feeding pipeline and connected with a programmable logic controller (PLC); the PLC is connected with the valves; and each liquid discharging branch is communicated with at least one liquid discharging nozzle. Compared with full-automatic filling equipment, the invention has the advantages that: the liquid discharging nozzles in the fields of manual filling and semiautomatic filling are used as filling interfaces of the soft infusion bags, the soft infusion bags with unstable shapes can be firmly clamped on the liquid discharging nozzles and be filled, and the soft infusion bag manual filling equipment can be used for filling the soft infusion bags with various conventional capacities such as 100ml, 250ml, 500ml and the like, and is particularly suitable for filling the soft infusion bags which are difficultly clamped by a full-automatic filling system and have the large capacity of more than 1,000ml.

Description

technical field [0001] The invention relates to a filling device, in particular to a semi-automatic filling device for infusion soft bags of more than 1000ml which are difficult to be clamped by existing automatic filling devices. Background technique [0002] Among the many medical products, infusion products are one of the categories with the largest consumption, among which glucose injection, sodium chloride injection, etc. are the main carriers for infusion drugs. Such carriers usually include glass bottles and plastic bottles. And soft bags three categories. In my country, most infusion products are loaded in glass bottles, but they have disadvantages such as large space occupation, heavy weight, fragility, low temperature resistance, difficult transportation, and high cost, and are gradually being replaced by infusion soft bags. However, due to the instability of the shape of the infusion soft bag, the traditional production line is difficult to meet the production ne...

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the need to manually load the bag, it is usually necessary to suspend filling when loading the bag, and the filling equipment is usually in a state of intermittent work, so the filling efficiency is low;

[0008] 2. The filling accuracy is low

[0012] 1. Due to the unstable shape of the infusion soft bag, the method of clamping the glass bottle cannot be used to clamp the infusion soft bag with an unstable shape, and the infusion soft bag still needs to be clamped manually;

[0013] Especially when the capacity of the infusion soft bag exceeds 1000ml, its shape is extremely unstable, and it is difficult to use the grasping method similar to glass or plastic bottles to realize the clamping and placing operation of the soft bag. The technology is difficult to realize, and the operation process is cumbersome. time consuming

If the above-mentioned quantitative filling device for the filling machine is used, the structure is complicated, the floor space is large, and the cost is high;

[0014] 2. There is only one liquid outlet, and the filling efficiency is low;

[0015] 3. Intermittent output of the liquid outlet. When the operator puts the infusion soft bag into the liquid outlet, the liquid needs to be suspended, and the filling efficiency is low;

[0016] 4. The dripping liquid left on the liquid nozzle is easy to drip and collect, causing environmental pollution
