Abstract
The utility model discloses a disposable piezometer pipe that lumbar vertebrae puncture used, including the crooked hard plastic pipe of 90 degrees, take the scale hose, take scale reservoir, infusion wheel valve, the waist needle is connected to the crooked hard plastic pipe one end of 90 degrees, and 90 degrees crooked hard plastic pipe other end connecting band scale hose one end is equipped with infusion wheel valve on the area scale hose, takes scale hose other end connecting band scale reservoir. Compared with the prior art, the utility model the advantage be: the utility model adopts the disposable piezometric tube to avoid iatrogenic infection; after the first connection, the lumbar puncture needle does not need to be moved; the pressure measurement can be completed simultaneously, the flow velocity is controlled, and the operation of reserving and taking a specimen is carried out on the drainage quantity.
Description
Technical Field
The utility model relates to a pressure-measuring pipe especially relates to a disposable pressure-measuring pipe that lumbar vertebrae puncture used.
Background
Lumbar puncture is a clinical routine operation, and the main purpose is to leave a cerebrospinal fluid sample for detection by detecting cerebrospinal fluid pressure. At present, the pressure measurement is performed by pulling out the needle core after the lumbar puncture is successful and connecting two glass tubes with scales, the drainage quantity (sample quantity) of cerebrospinal fluid is generally estimated by naked eyes, and if the cerebrospinal fluid pressure is too high, the flow is controlled by half inserting the needle core. The current method has the following disadvantages: 1. the glass piezometer tube is reused and has iatrogenic infection typing, in particular to prion diseases. 2. The needle core and the connecting needle tail interface need to be inserted and pulled out for many times, so that the position of the puncture needle can be changed, and the damage or the puncture depth can be caused. 3. The cerebrospinal fluid specimen is precious, the cerebrospinal fluid in the glass piezometer tube is easy to waste, and the glass piezometer tube is difficult and inconvenient to connect. 4. The control flow is not visual, 5, the cerebrospinal fluid detection items are increased at present, the required quantity of each sample needs to be accurate, and the visual inspection is unreliable. Therefore, the development of a disposable piezometric tube for lumbar puncture is a problem to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model provides a disposable piezometer tube for lumbar puncture, which solves the defects.
The above object of the present invention is achieved by the following technical solutions: the utility model provides a disposable piezometric pipe that lumbar vertebrae puncture used which characterized in that: including the crooked hard plastic pipe of 90 degrees, take the scale hose, take scale reservoir, infusion wheel valve, the needle is worn to the waist is connected to the crooked hard plastic pipe one end of 90 degrees, and the crooked hard plastic pipe other end of 90 degrees is connected band scale hose one end, is equipped with infusion wheel valve on the band scale hose, and the band scale reservoir is connected to the band scale hose other end.
Further, the length of the hose with the scales is 40 cm.
Compared with the prior art, the utility model the advantage be: the utility model adopts the disposable piezometric tube to avoid iatrogenic infection; after the first connection, the lumbar puncture needle does not need to be moved; the pressure measurement can be completed simultaneously, the flow velocity is controlled, and the operation of reserving and taking a specimen is carried out on the drainage quantity.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, a disposable piezometric tube that lumbar puncture used, including 90 degrees crooked hard plastic tube 1, take scale hose 2, take scale reservoir 3, infusion wheel valve 4, the needle (not shown) is worn to the waist is connected to 90 degrees crooked hard plastic tube 1 one end, and 90 degrees crooked hard plastic tube 1 other end is connected scale hose 2 one end, is equipped with infusion wheel valve 4 on the hose 2 of taking the scale, takes scale hose 2 other end to connect scale reservoir 4.
Further, the length of the hose 2 with the scale is 40 cm.
The utility model adopts the disposable piezometric tube to avoid iatrogenic infection; after the first connection, the lumbar puncture needle does not need to be moved; the pressure measurement can be completed simultaneously, the flow velocity is controlled, and the operation of reserving and taking a specimen is carried out on the drainage quantity.
