Description
Technical Field
The utility model belongs to the technical field of medical instrument and specifically relates to a liquid medicine translator.
Background
At present, when freeze-dried powder and powder injection contained in a penicillin bottle are used, liquid medicine or water for injection in a soft infusion bag needs to be pumped out through an injector and injected into the penicillin bottle until enough liquid medicine exists in the penicillin bottle; firstly, the syringe repeatedly pierces the rubber plugs of the penicillin bottle and the soft infusion bag, so that rubber scraps are easy to generate, and the needle contacts with the liquid medicine after contacting with air, and the factors cause the liquid medicine to be polluted, thereby causing the problem of medication safety; secondly, the traditional liquid preparation method is to firstly prepare the medicine and then inject the medicine, suck the medicine in the penicillin bottle into the soft infusion bag in advance, and then bring the soft infusion bag with the prepared medicine into a ward for infusion. After the medicine is dispensed, the empty penicillin bottle is put aside, and the patient and the medical staff are completely unaware of what medicine is dispensed in the infusion soft bag and have no traceability. Once medical care personnel pay little attention to the overflow of the liquid medicine during liquid preparation, or the liquid medicine is wrongly prepared and used, the health of the medical care personnel and the treatment of patients are seriously influenced; in addition, for some special medicines, such as medicines which need to be prepared and used immediately, the traditional preparation method is very inconvenient.
Also disclosed in the prior art is a mixing tip that can achieve mixing of drug and solvent by piercing only once:
CN202459338U discloses a double-needle medicine mixing nozzle with a protective sleeve, wherein the double-needle consists of a needle seat, an upper needle and a lower needle, the upper needle and the lower needle are arranged at two sides of the needle seat, the upper needle and the lower needle are both of hollow structures and are communicated with each other, the upper needle and the lower needle extend along the edge of the needle seat to the upper needle direction to form a medicine mixing body with a cup structure, and the lower needle is sleeved with a telescopic protective sleeve; at least two anti-slip buckles which are in the shape of a barb and used for preventing the penicillin bottle from loosening are symmetrically arranged on the inner wall of the medicine mixing body. Above prior art in mix the design of medicine mouth only need puncture once alright realize mixing the medicine, prevented the liquid medicine pollution, make things convenient for medical personnel to operate, realized that the process of dispensing is simple, convenient, safety.
However, the following drawbacks remain in the practical use of the above products: the liquid passage of a part of large transfusion packages on the market is not positioned at the circle center of the transfusion cover, and the double-valve transfusion cover is provided with two liquid passages which are not positioned at the circle center of the transfusion cover; in the using process after the medicine mixing cup and the infusion bag/bottle are connected, the problems of unstable connection, displacement, shaking or liquid medicine pollution caused by the sliding-out of the medicine mixing cup easily occur, so that serious potential safety hazards exist; in the process of clinical use of the existing medicine mixing cup, a penicillin bottle cannot be pulled out after being inserted, and the replacement of the penicillin bottle cannot be realized. In the in-service clinical use, it often has certain restriction to give the liquid volume, a bag of liquid need mix in several different medicines just can satisfy the dosage demand, the current medicine bottle that mixes that changes xiLin bottle can not realize that a bag of liquid corresponds xiLin bottle of a plurality of dosage units or a bag infusion corresponds several kinds of different xiLin bottle medicines, and simultaneously, mix the unable xiLin bottle that changes of medicine cup, cause xiLin bottle to abandon the joining that just can realize next xiLin bottle medicine together with mixing the medicine cup, the medical very big waste of mixing the medicine cup consumptive material that has led to the fact.
Patent application 201811260397.2 discloses a liquid medicine translator, this medicine mixing cup includes the card body that mixes the medicine, hollow cross needle and clamping structure. The clamping structure comprises an installation part and an elastic clamping jaw, and the medicine mixing clamping body comprises a plurality of annular cup walls arranged at intervals. The projections of the connecting ends of all the elastic clamping claws on the cross needle base along the axial direction form a first circle, the projections of the inner walls of all the annular cup walls on the cross needle base along the axial direction form a second circle, and the first circle and the second circle are partially overlapped. By designing the eccentric structure, the dosing port and the infusion port are separated in the operation process, the special port is special, and the infusion port is not exposed in the air during dosing, so that the secondary pollution of the infusion 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 repeated disinfection is not needed when the infusion port is opened for infusion, the disinfection cost is saved, the operation trouble of nurses is reduced, and the safety of clinical medicine application is greatly improved.
However, the needle point of the hollow cross needle structure is in a frustum structure, the inlet and the outlet of the hollow cross needle structure are circular, and the needle opening is small, so when liquid enters and exits, the inlet and the outlet are blocked due to liquid level tension, the liquid cannot smoothly circulate, and in addition, impurities such as particles, air and the like possibly mixed in the liquid cannot be removed in the medicine mixing process. In addition, because the inlet and the outlet are arranged at the top of the needle, when the liquid medicine is sucked back, a small amount of liquid medicine remains in the penicillin bottle under a normal state, and impurity particles in the penicillin bottle and in the operation process also enter the transfusion liquid along with the liquid medicine.
