Description
Technical field
The present invention relates to a kind of infusion pump linker, especially a kind of structure is simple, small in size, can reduce delay volume
Infusion pump in parallel integrated form linker.
Background technique
Critical component in infusion pump liquid chromatograph, main function are that driving mobile phase and sample pass through chromatography column
And detection system.Usually liquid inlet tee joint road connectivity structure is arranged in pump head liquid feeding end in existing parallel connection infusion pump, in pump head outlet end
Liquid triple channel connectivity structure is provided, the installation of relief valve triple channel connectivity structure at infusion pump outlets.Since three connections are tied
Structure is mutually indepedent, needs to be attached by connecting tube, and not only infusion pipeline is intricate, but also such as connecting line is too long, also
Delay volume can be increased, the normal detection of instrument is influenced.Also make that syringe structure is diverse and complicated, volume is big simultaneously.
Summary of the invention
The present invention is to propose that a kind of structure is simple, small in size in order to solve above-mentioned deficiency present in the prior art, can contract
The infusion pump in parallel integrated form linker of small delay volume.
The technical solution of the invention is as follows: a kind of parallel connection infusion pump integrated form linker has matrix, is equipped in matrix
Inlet tube connects hole, two pump head inlet tubes connect hole, two pump head outlets connect hole, pressure transmitter inlet tube connects hole, pressure becomes
Send device outlet to connect hole, pump housing outlet pipe connects hole, pump housing sewer pipe connects hole and blow valve, the inlet tube connect hole by first pipe
Road connects hole two with pump head inlet tube and communicates, and the pressure transmitter inlet tube connects hole and connects hole by the second pipeline and pump head outlet
It communicates two-by-two, the pump housing sewer pipe connects hole and communicates with blow valve, and the pressure transmitter outlet connects hole and passes through third pipeline
Hole is connect with pump housing outlet pipe respectively and blow valve communicates.
The present invention becomes one three connectivity structures, and mutual connecting line is omitted, and is guaranteeing without dead volume
Under the premise of product, the delay volume of infusion pump is reduced, the detection performance of equipment is improved.Meanwhile the configuration of the present invention is simple, body
Product is small, can be used for miniature or portable constant current infusion pump.

Specific embodiment
Infusion pump in parallel of the invention is as shown in Figure 1,2,3, 4 with integrated form linker, there is matrix 1, matrix 1 be equipped with into
Liquid pipe connects 2, two, hole pump head inlet tube and connects that 3, two, hole pump head outlet connects hole 4, pressure transmitter inlet tube connects hole 5, pressure
Transmitter outlet connects hole 6, pump housing outlet pipe connects hole 7, pump housing sewer pipe connects hole 8 and blow valve 9, and inlet tube connects hole 2 by the
One pipeline 10 connects hole 3 with pump head inlet tube and communicates two-by-two, and pressure transmitter inlet tube connects hole 5 and gone out by the second pipeline 11 with pump head
Mouth pipe connects hole 4 and communicates two-by-two, and pump housing sewer pipe connects hole 8 and communicates with blow valve 9, and pressure transmitter outlet connects hole 6 and passes through third
Hole 7 is connect with pump housing outlet pipe respectively for pipeline 12 and blow valve 9 communicates.
Connect as shown in figure 5, inlet tube is connect hole 2 with solvent bottle 13 when use, two pump head inlet tubes connect hole 3 respectively with
The inlet tube of in parallel the first pump head 14, the second pump head 15 connects, two pump head outlets connect hole 4 respectively with the first pump head 14,
The outlet of second pump head 15 connects, and pressure transmitter inlet tube connects hole 5 and connects hole 6 by connecting respectively with pressure transmitter outlet
The entrance and exit of pressure transmitter 16 is connect, pump housing sewer pipe connects hole 8 and connects with waste-solution line.
The course of work: when pump operation, the mobile phase in solvent bottle 13 connects hole 2 through inlet tube by inlet tube, passes through the first pipe
Road 10 connects hole 3 through pump head inlet tube to non-delay volume while entering the first pump head 14 and the second pump head 15, passes through the first pump head
14 and second pump head 15 by pump head outlet connect hole 3 through pump head outlet, the second pipeline 11, pressure transmitter inlet tube connect hole 5
Into pressure transmitter 16, the monitoring pump of pressure transmitter 16 flow path system pressure (damaging component with superpressure preventing) flows later
Hole 6 is mutually connect by pressure transmitter outlet, hole 7 is connect through pump housing outlet pipe to non-delay volume and flows out.When the unscrewing of blow valve 9, pump
Outlet connects the closure of hole 7, and mobile phase and internal system bubble connect hole 8 through pump housing sewer pipe and be discharged into waste-solution line.
