The lower face of card body.One end of hose is sleeved in medicine mixing port, and with the medicine mixing port soldering, the other end of hose is sleeved on syringe
On body, and with the needle cylindrical unit soldering.
But before mixed medicine is implemented, the infusion solvent in transfusion flexible bag easily contacts said structure with medicine feeding needle, makes infusion
Solvent is poured by medicine feeding needle in mixed medicine card body, so as to generate leakage, causes the pollution before use, influences the peace of mixed medicine process
Full health.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, to add for shortcoming in the prior art and problem
To improve, innovate, a kind of screw-type sealing simple in structure, easy to use, making infusion safer is provided and is made up a prescription lid double nip,
It is threaded in outer cover for sealing the lid that makes up a prescription, and is matched with medicine mixer and facilitates infusion；By being set in mixed medicine passage
One is used for the membrane of sealed mixed medicine passage, makes the infusion solvent in transfusion flexible bag that sealing be kept to be avoided without being contacted with medicine feeding needle
Infusion solvent is poured by medicine feeding needle in mixed medicine card body, so as to generate leakage, both it is stringent ensure that infuse in transfusion flexible bag it is molten
The volume of agent in turn avoids the pollution before use.
In order to solve the above technical problems, the utility model uses following technical proposals：
A kind of threaded formula seals the lid double nip that makes up a prescription, and including medicine mixing port, infusion connector, pedestal and medicine mixer, mixes medicine
It is mixed medicine passage between interface and pedestal, is infusion channel between infusion connector and pedestal, the infusion connector connection sealing is matched somebody with somebody
Medicine lid, medicine mixing port connection screw thread formula sealing are made up a prescription lid, and the screw-type sealing makes up a prescription to cover and includes outer cover, rubber cushion and interior
Lid, the outside of cover top portion are equipped with easy draw piece, form a chamber on the inside of outer cover, chamber is embedded with rubber cushion and inner cover, inner cover
Top connects with rubber cushion and rubber cushion is made to be caught in the chamber of outer cover, and the lateral wall of inner cover opening edge connects with the madial wall of outer cover,
The edge of opening of outer cover and inner cover is coplanar, and edge of opening and the medicine mixing port of outer cover and inner cover are tightly connected, the screw-type
It seals outer cover of the lid that makes up a prescription and is provided with external screw thread, internal thread is provided on the medicine mixer and is connected with the external screw thread of outer cover, institute
It states and a membrane for being used for sealed mixed medicine passage is equipped in mixed medicine passage.
Preferably, state projection of the pedestal in its cross section in ship shape structure, and the ship shape structure pedestal both ends to
It is outer to extend to form the gradual thinning thin slice of thickness.
Preferably, the infusion connector makes up a prescription to cover with sealing and is connected for heat seal.
Preferably, the medicine mixing port is made up a prescription to cover and is connected for heat seal with screw-type sealing.
A kind of threaded formula sealing of the utility model is made up a prescription lid double nip, it covers setting spiral shell in sealing the outer of lid that make up a prescription
Line matches with medicine mixer and facilitates infusion；By setting a membrane for being used for sealed mixed medicine passage in mixed medicine passage, make defeated
Infusion solvent in liquid soft bag keeps sealing without being contacted with medicine feeding needle, and infusion solvent is avoided to pour into mixed medicine card body by medicine feeding needle
In, so as to generate leakage, both the stringent volume that ensure that solvent of infusing in transfusion flexible bag in turn avoided the pollution before use.
