Further, rotary valve includes the shifting block of sleeve and relative sleeve rotation, and shifting block and hemispherical baffle pass through swingle
It is fixedly connected.
Further, scale casing ruler is elastic material, can opposite sliding between graduated scale casing and connecting tube.
Further, the nut cap to match with venthole is hinged on venthole.
Further, the protective case to match with syringe needle is arranged on syringe needle.
Further, fixed frame is pyramidal structure wide at the top and narrow at the bottom, is equipped on the end face of fixed frame left and right side anti-skidding
Rib.
The utility model has the beneficial effects that:
1, the utility model is used for the infusion apparatus of measurement of central venous pressure, opens up and syringe needle and connecting tube in the middle part of fixed frame
The through-hole communicated also opens up the venthole communicated with through-hole on fixed frame upper surface, activity installation and venthole phase in venthole
Matched hemispherical baffle, is fixedly connected between hemispherical baffle and shifting block by swingle, by rotating shifting block, so that shifting block
On hemispherical flapper.When shifting block rotates down, hemispherical baffle blocks venthole, so that syringe needle is in connecting tube
Liquid in infusion bottle is imported in connecting tube by syringe needle and is exhausted by unimpeded state；It is calm in patient when needing to measure
When pulse pressure, shifting block can be rotated up, hemispherical baffle blocks the through-hole that side is communicated with syringe needle, so that venthole and company
Adapter tube is in unimpeded state, and the liquid in connecting tube moves down under atmospheric pressure, until the liquid in connecting tube stops
Numerical value corresponding to liquid in connecting tube is measured after only gliding, by the infusion apparatus measuring center vein pressure, does not need to be infused
Syringe needle on device is extracted from infusion bottle, avoids syringe needle for transfusion device exposure in air, there are contaminated risks.
2, the utility model is used for the infusion apparatus of measurement of central venous pressure, and the scale set of elastic material is arranged outside connecting tube
Pipe ruler, the scale casing ruler can be slided with respect to connecting tube, can be moved scale casing ruler along connecting tube in this way, can
With any position of connecting tube carry out zero mark, eliminate and mark scale value in connecting tube, at the same also by can one doctor
Business personnel one man operation, has saved the nurse job time, easy to operate, is conducive to the early recovery of patient.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the transfusion system structure schematic diagram that the utility model is used for measurement of central venous pressure；
Fig. 2 is the infusion apparatus side structure schematic diagram that the utility model is used for measurement of central venous pressure.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
