Aluminum-plastic gland opening device for vials

Abstract

The invention discloses an aluminum-plastic gland opening device for vials, which is characterized by comprising a base, a support, a retaining plate, a tooth holder, supporting teeth, vial fixing seats, auxiliary slideways, an impact air cylinder, vial positioning frames, a driving motor, a bidirectional lead screw and a control device. Guide rails are respectively arranged on two sides of the upper end of the base, the bidirectional lead screw is arranged in the middle of the base, the auxiliary slideways are arranged on two sides of the base, two ends of the bidirectional lead screw are fixedly connected with the base, a support is arranged in the middle of the upper ends of the guide rails, the vial fixing seats are arranged on two sides of the support, a retaining plate is arranged at the upper end of the support, the impact air cylinder is arranged in the support, the lower ends of the vial fixing seats are fixedly connected with the guide rails, vial seat slots are arranged at the upper ends of the vial fixing seats, the centers of the lower ends of the front positioning frame and the rear positioning frame are in threaded connection with the bidirectional lead screw through nuts, two sides of the front positioning frame and the rear positioning frame are in rolling connection with the guide rails, the upper portions thereof are in sliding connection with the auxiliary slideways, the tooth holder is arranged at the upper end of the telescopic rod of the impact air cylinder, and the supporting teeth are arranged on the periphery of the tooth holder. The aluminum-plastic gland opening device has the advantages of novel structure, convenience in operation, fastness in use, time-saving and labor-saving effect, high working efficiency, low labor intensity and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an opening device for an aluminum-plastic pressure cap of a vial. Background technique [0002] Existing vials for antibiotics are composed of a bottle body and a combined cap. The combined cap includes a rubber stopper and an aluminum-plastic gland. The rubber stopper in the combined cap is easy to contact with the medicine in the bottle during storage and transportation. It contains rubber, vulcanizing agent, vulcanization accelerator, filler, plasticizer, protein molecules and other components. After contacting with some drugs with relatively strong molecular activity, it is easy to be absorbed, adsorbed, leached, and infiltrated by drugs, resulting in rubber plugs and drugs. Compatibility problems, especially some cephalosporins, some large infusions, and more traditional Chinese medicine injection preparations, etc., which affect the quality of medicines. In order...

Problems solved by technology

[0002] Existing vials for antibiotics are composed of a bottle body and a combined cap. The combined cap includes a rubber stopper and an aluminum-plastic gland. The rubber stopper in the combined cap is easy to contact with the medicine in the bottle during storage and transportation. It contains rubber, vulcanizing agent, vulcanization accelerator, filler, plasticizer, protein molecules and other components. After contacting with some drugs with relatively strong molecular activity, it is easy to be absorbed, adsorbed, leached, and infiltrated by drugs, resulting in rubber plugs and drugs. Compatibility problems, especially some cephalosporins, some large infusions, and more traditional Chinese medicine injection preparations, etc., which affect the quality of medicines. In order to solve this problem, it is generally used to cover the top surface of the rubber stopper with a layer A film with stable performance and good compatibility with drugs can prevent the drug from directly contacting the rubber stopper, but the production process of this kind of rubber stopper is very complicated and the cost is high

Another method is to use the aluminum-plastic gland to compress the rubber stopper and the bottle mouth, and then roll the aluminum-plastic gland to the bottle mouth. The disadvantage is that the nurse needs to put a lot of vials when infusion for the patient. When the aluminum-plastic glands are opened, nurses can only use a screwdriver to manually break the aluminum-plastic glands of these vials one by one, which is labor-intensive, time-consuming and labor-intensive, and the work efficiency is extremely low
