Description
Technical field
The present invention relates to medical instruments field, especially a kind of chemotherapeutics mixing arrangement.
Background technology
In the medical field, when treating tumour and common disease, it is often necessary to mix treatment medicinal powder and liquid, so
Hybrid medicine is injected into human body by syringe or infusion apparatus.Existing admixing medical solutions, medicinal powder method mainly pass through syringe
After extracting liquid bottle liquid medicine, then liquid is injected into powdered medicine bottle and carries out mixed diluting；The medicine being pumped into every time due to syringe
Liquid measure is limited, therefore when the liquid by larger dose is needed to extract out and be input in powdered medicine bottle, it is often necessary to which troublesome operation is several
It is secondary to can be only achieved needs；In fact, due to the particularity of medical industry, it is very high to sterile requirement, it is mixed using the above method
There is very big shortcoming in medicinal powder, liquid, easy in this way due to that can be exposed in air before being inserted into powdered medicine bottle after injection needle suction liquid
Injection needle is allowed by bacterium infection in surrounding air, injection needle, which is inserted into after medicinal powder box, causes in medicinal powder box admixing medical solutions by bacterium
Infection so as to cause the risk increase of patient's body input admixing medical solutions postoperative infection harmful bacteria, is repeatedly extracted in injection needle
When liquid medicine injection is used as medicine in powder box, the probability bigger of bacterial infection in patient body.
Invention content
It, can be to medicinal powder, liquid medicine box inner liquid medicine side in medicinal powder box without a kind of suitable tool in order to overcome in medical field
Just the drawbacks of mixing, patient can be caused to infect harmful bacteria, the present invention provides medicinal powder, liquid medicine box inner liquid medicines in mixed powder box
When, by lower contact pin be inserted into medicinal powder box in, upper contact pin be inserted into liquid medicine box in after, liquid medicine box inner liquid medicine can be automatically flowed into medicinal powder box,
And can also facilitate by manipulating flow valve, control flows into the dosage of medicinal powder box inner liquid medicine, so as to can not only meet liquid and
Discord outside air is in contact when medicinal powder mixes, and is reduced patient and is infected the risk of harmful levels of pathogens, and control can also be facilitated to flow
A kind of chemotherapeutics mixing arrangement for powder box inner liquid medicine amount of being used as medicine.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of chemotherapeutics mixing arrangement, it is characterised in that including annular connecting seat, upper contact pin, lower contact pin, flow valve,

End, upper contact pin, the through-hole of lower contact pin internal openings and connecting seat middle part from top to bottom connect, and laterally there are one columns in the middle part of connecting seat
Shape slot, the right part of cylindrical groove is Open architecture, has internal thread, the middle part upper and lower ends of cylindrical groove on the inside of the right end of cylindrical groove
Respectively there are one trepanning, cylindrical groove middle part upper and lower ends trepanning is connected with the through-hole in the middle part of connecting seat from top to bottom, flow valve
Including spring, piston, push rod, installation lid, handle, from top to bottom there are one through-hole, installation lid is opened there are one middle parts at piston middle part
Hole, installation lid left-hand end have external screw thread, and spring is placed in cylindrical groove left end, and push rod left part is mounted on piston right end, push rod
Right part passes through the trepanning at installation lid middle part, by installing the internal thread screwed on the inside of cylindrical groove right end of lid left part,
Installation lid is mounted on the right end of cylindrical groove, and taper knob is on push rod right-hand end.
The annular connecting seat, the piston of flow valve, push rod, installation lid, handle are medical grade silica gel materials.
The upper contact pin, lower contact pin and flow valve spring are stainless steels.
The top of the upper contact pin is ramp structure to middle part, and the lower part of lower contact pin to middle part is ramp structure.
When the upper contact pin, lower contact pin are separately mounted to annular connecting seat middle through-hole upper and lower ends, the lower end of upper contact pin
The upper end of annular connecting seat middle through-hole is inserted under heated condition, is inserted under the upper end heated condition of lower contact pin in annular connecting seat
The lower end of portion's through-hole, in interference fit shape between the lower end of upper contact pin, the upper end of lower contact pin and annular connecting seat middle through-hole
State,
The right end of the flow valve piston is there are one circular mounting groove, and push rod left part is circular configuration, push rod left part
Circular configuration position outer diameter is bigger than piston right end circular mounting groove internal diameter, and push rod left part circle position is sleeved on piston right end circle
In installation groove, push rod left part circle position and piston right end circular mounting groove are in interference fit state.
There are one trepannings for the flow valve middle handle, and the right end outer diameter of push rod is bigger than middle handle trepanning outer diameter, hand
Trepanning is sleeved on push rod right-hand end under handle heated condition, and interference fit state is between handle and push rod.
Present invention has the advantages that：The utility model finished product is packed into sterile bag and preserves for use, due to all using medical grade
Sterilizable material makes, and can prevent material from causing health effect to patient in itself.In use, after dismantling sterile bag, upper contact pin is inserted
In the serum cap for entering liquid medicine box lower end, lower contact pin is inserted into the serum cap of medicinal powder box upper end；Then with finger flow valve
Handle turn left pressure, after from top to bottom through-hole and connecting seat middle through-hole penetrate through in the middle part of piston, liquid in liquid medicine box can be through
It is flowed into medicinal powder box in connecting seat middle through-hole, piston middle through-hole, upper and lower contact pin, after the liquid of medicinal powder box lower end is suitable,
Operator's release handle, then, under the elastic acting force of spring, piston moves right, piston middle through-hole no longer and connection
Seat middle through-hole perforation, liquid are also no longer flow into the medicinal powder box of lower end, reach the liquid volume of operator's needs.The utility model is entire
In the process, it is not exposed in air during upper and lower contact pin conveying liquid, effectively prevents outside air bacterium to drug mixture
Pollution, and grasp medicinal liquid flow can be facilitated, based on application prospect above-mentioned, that the utility model has had.
