Description
Technical field：
It the utility model is related to technical field of medical instruments, more particularly to a kind of disposable cerebrospinal fluid pressure-measuring pipe.
Background technology：
The human cerebrospinal fluid pressure-measuring pipe clinically commonly used at present, it is typically with a scale made of glass or high polymer material
Transparent short tubule or long tubule form with union elbow, in use, pressure-measuring pipe is perpendicular to the ground, the union elbow mouth of pipe is logical with puncturing
Road connects, and when the measured cerebrospinal pressure is larger, i.e., height of the cerebrospinal fluid in pressure measuring tube exceedes single-unit short tube height
During applicable pressure measurement range, it is usually another single-unit tubule of the Guan Shangzai continued accesses, increases measurable range, to meet to measure
Need.But two section single tube continued accesses are used in use, operator usually needs a hand steered site of puncture to stablize first to be stably connected with
Section is managed, and to take the double section tube extended on the other hand in addition, after 2-section pipe connection, uses in addition stable 2-section pipe junction on the other hand, together
When also to read scale on pipe, measure pressure value.The method is extremely inconvenient.As directly used the longer tubule of single-unit, though avoid
The troublesome operation of continued access pressure-measuring pipe, but if directly use long tube, stability of the pressure-measuring pipe in vertical survey is not only reduced,
And the packaging for puncturing sterile package will be caused to increase, and increase sterilization and packing cost, and accumulating carrying is inconvenient.
In order to measure patient's cerebrospinal pressure, it is necessary in lumbar vertebrae lancet puncture, after puncturing successfully, puncture backshank and be connected to
L-shaped pressure-measuring pipe, lancet puncture depth judge by rule of thumb with doctor entirely, not enough accurately.In addition, it is at the top of existing L-shaped pressure-measuring pipe
Opening, is communicated with air, is easy to measure cerebrospinal pressure.Because the disease condition of each patient is different, some patient's cerebrospinal fluid
Pressure is higher, and often cerebrospinal fluid sprays from L-shaped pressure-measuring pipe open top end, and doctor, which has to vacate a hand, to come with finger always
Open top end is blocked, and operating lumbar puncture needle needs two hands of doctor to be used in combination, therefore, such case often makes doctor to connect
It is too busy, also needs other people to aid in sometimes.
Sum it up, current pressure-measuring pipe more or less has a little defects, the use to medical personnel brings inconvenience.
Utility model content：
The utility model is in order to overcome drawbacks described above present in prior art, there is provided a kind of disposable cerebrospinal fluid pressure measurement
Pipe.
To solve the above problems, the utility model proposes disposable cerebrospinal fluid pressure-measuring pipe, including：Elastic pressure-measuring pipe, three
Pass joint, syringe needle flexible pipe, syringe needle, three interfaces of the three-way connection are respectively hose connection, pressure measurement interface tube and drainage tube
Interface, the syringe needle are detachably connected with syringe needle flexible pipe sealing, and the syringe needle flexible pipe seals removable with the hose connection
Connection is unloaded, the elastic pressure-measuring pipe is detachably connected with the pressure-measuring pipe sealing joint, and the drainage tube interface is drawn for connection
Flow tube, length scale line is provided with the syringe needle, the elastic pressure-measuring pipe axial side wall is provided with graduation mark, and the elasticity is surveyed
It is provided with pressure pipe and pastes band, is pasted after the elastic pressure-measuring pipe firmly to be bent to annular shape in the not used time described in fixed
Type, open during use described in paste band, the elastic pressure-measuring pipe reverts to straight-tube shape under its own resilient, length is set on syringe needle
Degree graduation mark is easy to determine the insertion depth of syringe needle.
In above-mentioned technical proposal, the top lower sidewalls of the elastic pressure-measuring pipe are fixedly installed the work with suspension arm
Plug, the piston are wholely set with elastic pressure-measuring pipe, are easy to block the elastic pressure-measuring pipe at any time.
In above-mentioned technical proposal, a sealing-plug is fixedly installed at the drainage tube interface, the sealing-plug is used for only
Plug for seal drainage tube interface in the case of pressure measurement is needed without drainage.
The utility model is had the advantages that compared with prior art and advantage：
The utility model proposes disposable cerebrospinal fluid pressure-measuring pipe in piston setting can avoid cerebrospinal fluid spray it is excessive,
Being advantageous to save sample, reduce pollution, the length of elastic pressure-measuring pipe is longer to be easy to measure, and can be bent and is easy to pack and transport,
The setting of three-way connection disclosure satisfy that while the requirement of pressure measurement and drainage, overall structure are simple and convenient to operate, are easy to sample, pacify
It is complete reliable.
