Transfusion joint clamping seat
Technical Field
The utility model relates to a medical instrument, in particular to an infusion connector clamping seat.
Background
The existing injection package generally adopts a penicillin bottle or an ampoule bottle, and the powder injection uses the penicillin bottle and the water injection uses the ampoule bottle under normal conditions. When traditional liquid preparation is carried out, a syringe is adopted to transfer the medicine, and the specific mode is as follows:
1. preparing a penicillin bottle medicament: extracting the liquid medicine in the soft infusion bag through the injector, injecting the liquid medicine into the penicillin bottle, repeatedly shaking the penicillin bottle until the powder injection in the penicillin bottle is fully dissolved, extracting the liquid medicine in the penicillin bottle through the injector, and injecting the liquid medicine back into the soft infusion bag;
2. preparing ampoule bottle medicine: firstly, breaking the bottleneck of the ampoule bottle, then using a syringe to draw out the liquid medicine in the ampoule bottle, and then injecting the liquid medicine into the soft infusion bag.
In the traditional liquid preparation method, the needle head of the syringe is completely exposed in the air in the whole liquid preparation process, and the liquid medicine is easily polluted.
In order to overcome the defects, patent CN 209751664U discloses a medicine mixing cup with a clamping structure, which is suitable for a double-valve infusion cap, and comprises a medicine mixing clamp body, a cross needle and a clamping structure. The connecting ends of all the elastic clamping claws form a circle along the axial projection, and the root of a hollow cross needle arranged along the axial direction is positioned at one needle opening of the double-valve transfusion cover. The medicine mixing cup is suitable for the double-valve transfusion cover, so that a medicine adding port and a transfusion port are separated in the operation process, the special port is special, the transfusion port is not exposed in the air during medicine adding, and the secondary pollution of the transfusion port is avoided; the infusion port and the medicine adding port are not in the same tube during medicine adding, and the infusion port is not opened, so that the infusion port is not required to be disinfected when opened for infusion, and the safety of clinical medicine application is greatly improved.
Although the above patents can realize the airtight butt joint of the penicillin bottle and the infusion soft bag interface and prevent the liquid medicine pollution, the following defects exist: firstly, during infusion, the medicine mixing cup is required to be pulled out of an infusion soft bag interface, and then the infusion needle can be inserted into another puncture hole on the infusion cover, so that the operation steps are increased, the requirement on the fineness of medical personnel is higher, and once the medicine mixing cup is carelessly punctured twice by the same puncture hole, the scraps can enter the infusion soft bag; secondly, the airtight butt joint of the ampoule bottle and the soft infusion bag interface cannot be realized, and the existing prescription generally has the phenomenon of coexistence of multiple dosage forms (packaging bottles), so that only the airtight butt joint scheme of the penicillin bottle is provided, and the airtight preparation of the whole prescription cannot be fundamentally solved, namely, if medicine prescriptions of different bottle types need to be prepared, particularly when medicine liquid in the ampoule bottle needs to be mixed, the prior art also needs to adopt an injector to transfer the medicine liquid, and the risk of pollution of the medicine liquid caused by the fact that a needle head of the injector is exposed in the air also exists.
