Liquid output magazine is arranged along governor body length direction and position is corresponding with blood output hole site；Link slot connects blood input
The big end and blood output magazine of slot；Adjusting rod is arranged in the same direction with adjuster core, and adjusting rod outside governor body by extending to
Portion is simultaneously threadedly coupled with adjuster core, and location structure is provided on adjusting rod, and location structure limits adjusting rod relative to adjuster
The axial movement of shell；Locating rod quantity is two, and locating rod is arranged and is connect with governor body, two with adjuster core in the same direction
A locating rod is inserted into two location holes respectively.
It is further：Two location holes are symmetrical arranged centered on the axis of adjuster core.
It is further：Governor body is made of clear material, and is provided with scale on governor body, on adjuster core
It is provided with Warning Mark, the scale value that Warning Mark is directed toward indicates transfusion speed.
The utility model has the beneficial effects that：Degree of regulation is high, can accurately adjust transfusion speed, and can show that
Transfusion speed.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
In order to provide a kind of accurate transfusion speed adjuster of adjusting, as shown in Figures 1 to 4：Transfusion speed adjuster packet
Include governor body 1, adjuster core 7, adjusting rod 5 and locating rod 9；Blood input hole 2 and blood are provided on governor body 1
Delivery outlet 8；Adjuster core 7 is located in governor body 1 and moves, and is sealed between adjuster core 7 and governor body 1, adjusts
It is provided with blood input slot 3, blood output magazine 6 and link slot 10 on the surface of device core 7, it is axially disposed in adjuster core 7 to have
Two location holes 11；Blood input slot 3 is arranged along 1 length direction of governor body and position is corresponding with 2 position of blood input hole,
The shape in the section of the length direction of blood input slot 3 is triangle；Blood output magazine 6 is set along 1 length direction of governor body
It sets and position is corresponding with blood output hole site；Link slot connects the big end and blood output magazine 6 of blood input slot 3；Adjusting rod 5
With adjuster core 7 in the same direction be arranged, adjusting rod 5 by extending to inside outside governor body 1 and being threadedly coupled with adjuster core 7,
Location structure 4 is provided on adjusting rod 5, location structure 4 limits axial movement of the adjusting rod 5 relative to governor body 1；It is fixed
Position 9 quantity of bar is two, and locating rod 9 is arranged with adjuster core 7 and is connect with governor body 1 in the same direction, and two locating rods 9 are divided
It Cha Ru not two location holes 11.Two location holes 11 are symmetrical arranged preferably centered on the axis of adjuster core 7.
The utility model is connected on blood transfusion tube, 2 blood delivery outlet 8 of blood input hole is connected to blood transfusion tube, you can into
Row transfusion speed is adjusted.
The principle that the utility model adjusts transfusion speed is as follows：Rotation adjusting lever 5 is adjusted due to the limitation of location structure 4
Bar 5 cannot be axially moved；Due to the limitation of locating rod 9, adjuster core 7 cannot rotate；Under the action of screw thread, adjuster core 7
It is axially moved so that the different location alignment blood input hole 2 of adjuster core 7.When the end alignment blood of adjuster core 7 inputs
Hole 2,7 closed blood input hole 2 of adjuster core, without blood transfusion.When the different location of blood input slot 3 is directed at blood input hole
2, the slot bottom of blood input slot 3 changes with the gap of governor body 1 so that transfusion speed changes.7 moving process of adjuster core
In, blood output magazine 6 is connected to blood delivery outlet 8 always.
In order to show that transfusion speed, governor body 1 are made of clear material, quarter is provided on governor body 1
It spends, Warning Mark is provided on adjuster core 7, the scale value that Warning Mark is directed toward indicates transfusion speed.
