Problems solved by technology
[0004] The drug dosing instrument with the above structure mainly has the following disadvantages in the drug mixing process: when the drug container is stuck into the drug mixing card body, the sealing film on the top of the drug mixing card body must be torn off first, and the drug mixing card must be opened when it is inserted. experience contact with the outside world, thereby causing pollution
And all the closed dosing instruments that appear in the prior art can only realize the airtightness in the mixing process, but cannot realize the "whole process aseptic airtightness" during the docking of the vial and the dosing instrument, the mixing of medicines and the infusion. "

Embodiment 2
[0040] The difference between the second embodiment and the first embodiment is that the bottom end of the guide sleeve I3 is sealed butt joint with the top end of the mixing card body 1, the guide sleeve II6 is located inside the guide sleeve I3, and the guide sleeve II6 and the rotating sleeve 4 are integrally formed. The rotating sleeve 4 and the guide sleeve I3 form an axially fixed and radially rotatable fit, and the rotating sleeve 4 and the guide sleeve I3 are sealed and matched (in this embodiment, a ring card 18 is arranged on the top of the inner wall of the guide sleeve I3 along the circumferential direction. The top surface of the sleeve I3 is provided with an annular groove 19 along the circumferential direction. After the rotating sleeve 4 is installed on the guide sleeve I3, the ring card 18 is located in the ring groove 20, and a sealing ring 11 is installed in the ring groove 19. The ring 10 is pressed on the top end of the guide sleeve I3 through the sealing r...

The invention discloses a short-course preassembling type dosing instrument which comprises a medicine mixing clamp body, dosing double needles, a guiding sleeve I, a rotating sleeve and a guiding part, wherein the guiding sleeve I is arranged between the medicine mixing clamp body and the rotary sleeve, one end of the rotary sleeve is in sealing connection with the top end of the medicine mixing clamp body, the guiding sleeve I and the rotating shelve form axial fixing matching, and the guiding part is arranged in the guiding sleeve I and driven to move axially along the guiding sleeve I by the rotating sleeve. When the short-course preassembling dosing instrument is used, a medicine container and the dosing double needles are in a sealing state by means of a membrane and the rotating sleeve in an interface, and thorough sterility in transportation and storage can be achieved. The guiding part is driven to move rapidly downwards and push the medicine container by rotating the rotating sleeve, upper needle points of the dosing double needles puncture a sealing plug on the medicine container, and the lower needle points of the dosing double needles puncture the membrane in the interface, so that the medicine container is instantly communicated with a transfusion container, and therefore, sterile sealing in the whole processes of transportation, storage, butt jointing, medicine mixing and transfusion is achieved.
Description
technical field [0001] The invention relates to a medical device, in particular to a dosing instrument for mixing medicines. Background technique [0002] In order to add the medicine in the medicine container to the solution in the infusion container (i.e. infusion soft bag or infusion soft bottle), and then infuse the mixed solution into patients in clinical institutions such as hospitals. In the prior art, a drug dosing instrument is often used to connect the drug container with the infusion soft bag or the infusion soft bottle. [0003] The dosing instrument in the prior art mainly includes a drug mixing card body and a drug dosing double needle. The drug mixing card body forms a cup-shaped structure. For sealing, a diaphragm is provided on the bottom inner wall cross-section of the drug mixing card body, and a sealing film is provided on the top of the drug mixing card body. The upper sealing film corresponds. When in use, connect the drug mixing card body with the i...
