A medicate cup having an eccentric needle structure

Abstract

The invention relates to a medicine mixing cup having an eccentric needle structure. The medicine mixing cup comprises a medicine mixing card body, a hollow cross needle and a clamping structure. Theclamping structure comprises a mounting part and an elastic jaw, and the mixing card body comprises a plurality of annular cup walls arranged at intervals. The projection of the connecting ends of allthe elastic jaws on the cross needle holder in the axial direction forms a first circular shape, and the projection of the inner walls of all the annular cup walls on the cross needle holder in the axial direction forms a second circular shape, and the first circular shape and the second circular shape partially overlap. The unique structural design of the medicine mixing cup improves the stability of the connection between the medicine mixing cup and the infusion container and enhances the safety of clinical medication.

Description

technical field [0001] The invention relates to a medicine mixing cup, in particular to a medicine mixing cup with an eccentric structure. Background technique [0002] At present, when using powder injections, freeze-dried, and powder injections contained in vials, it is necessary to extract the liquid medicine or water for injection from the infusion soft bag into the vials through a syringe, and repeat the above work until there is enough liquid medicine in the vials Then the vial is shaken repeatedly until the medicament in the bottle is evenly mixed, and then the medicinal liquid in the vial is extracted and injected into the soft infusion bag with a syringe, and so on, until the medicinal liquid in the bottle is exhausted. Such an operation has many disadvantages: [0003] First of all, the syringe repeatedly punctures the rubber stopper of the vial and the large infusion solution package, which not only easily produces rubber crumbs, but also the needle contacts the ...

Problems solved by technology

[0009] But, still following defect in the actual use of above-mentioned product: 1) the liquid path of the part big infusion package on the market is not positioned at the center of circle of infusion cover, for example the double-valve infusion cover on the market (such as Figure 5 As shown) there are two liquid passages, and none of them are located at the center of the infusion cap; 2) After the mixing cup is connected to the infusion bag / bottle, it is easy to cause unstable connection, displacement, shaking, or drug mixing during use The slipping of the cup leads to the problem of contamination of the liquid medicine, so there is a relatively serious safety hazard; 3) In the process of clinical use of the existing mixing cup, the vial cannot be pulled out after being inserted, and the replacement of the vial cannot be realized

In actual clinical use, the amount of liquid given is often limited. One bag of liquid needs to be mixed with several different drugs to meet the dosage requirements. Using the existing mixing cup that cannot replace the vial can not achieve a bag of liquid. Multiple dosage units of vials or a bag of infusion correspond to several different vials of medicines. At the same time, the mixing cup cannot replace the vials, causing the vials and mixing cups to be discarded together to realize the addition of the next vial of medicine, resulting in Great waste of medical mixing cup consumables
