Description
Technical field
The present invention relates to the field of medical instrument technology, specially a kind of disposable simple center for cardiac operation
Vein manograph.
Background technique
When urgent patient needs to carry out infusion treatment during surgery to sufferer in carrying out cardiac operation, and use
Central venous catherization is a kind of directly effective mode being directly administered in openheart surgery to sufferer body, and central vein is surveyed
Pressure is then to have one to understand in detail for the heart correlation function preferably to sufferer, is detected when surveying and press by central vein
Whether normal value can reflect out heart to the ability that pumps out of blood back amount, and prompt venous return sufficient；When measuring center
When vein pressure is excessively high, can there is that fluid infusion is excessive or too fast, has heart failure, vessel retraction, pericardial tamponade, acute or chronic pulmonary artery
Hypertension, mechanical ventilation and high non-positive pressure equally likely possibility of exhaling；When measure center pulse pressure it is too low when, can exist hypovolemia,
Blood vessel dilatation, the not normal equally likely possibility of vascular function, therefore there is more important meaning in clinic.
In the prior art, it generally being measured using pressure-measuring pipe when central vein surveys pressure, this measurement method is relatively simple,
But it has the following deficiencies place in actual use:
1. because of the reason of installation and execute-in-place, pressure-measuring pipe meeting run-off the straight or beat phenomenon, therefore will lead to the reading of measurement
Number is inaccurate, reduces the accuracy of measurement；
2. measurement pipe, during installation, zero-bit is required with the right atrium of patient in same level height, because of sufferer
The placement reason in the orientation or bed body that lie down, will appear certain height tolerance after installation, and this height tolerance passes through repetition
Installation, which is adjusted, is unable to reach satisfied effect；
3. the upper end of measurement pipe is directly contacted with outside air, lack effective preventive means, improves what sufferer was infected
Probability.

Altitude scale label 402 side and in the outer circle of graded tube 401 be equipped in upper, middle and lower arrangement high-low pressure label
403, red greenish-yellow tricolor marker is had on the label of high-low pressure label 403 herein, is respectively represented from high to low by its mark position
High pressure, positive normal pressure and low pressure, wherein the effect of altitude scale label 402 is read in the outer circle in order to direct graded tube 401
The reading of liquid level is measured, and the effect of high-low pressure label 403 is directly to differentiate measurement result from reading is upper in order to more eye-catching
Within the scope of which, and then it can quickly make anticipation and feedback.
In Fig. 5: the top of graded tube 401 is equipped with the end tank 404 of trough body structure, the intermediate fixed peace of end tank 404
Equipped with filter cotton 405, filter cotton 405 is chosen as nano silver filtering cotton herein, and the upper end button of end tank 404 is equipped with pressing sleeve 406, when
Outside air can form filtrated air when entering in 401 cavity of graded tube by the filter sterilization of filter cotton 405, therefore reduce
Entire manograph with extraneous infection probability.
Working principle: when installation, first by fixing sleeve 102 with 101 sets of guide sleeve be stuck on the transfusion pole of the head of a bed, pay attention in order to
Opposite sliding between fixing sleeve 102 and transfusion pole is prevented, one layer of glue can be first wrapped up on the transfusion pole of 102 corresponding position of fixing sleeve
Cloth, then rotation roulette 105 makes adjusting screw rod 104 and fixing sleeve 102 is spirally connected rotation, and then makes guide sleeve 101 along guide rod 103
Guiding finely tune upward or downward, pay attention to position height adjusted, make " 0 " of 401 outside height scale mark 402 of graded tube
Sufferer atrium dextrum position keeps sustained height on scale mark and bed, then adjusts 307 valve body 3 of adjusting knob, respectively will
Feed liquor pipe connector 302 is connected with perfusion tube, and outlet tube connector 303 is connected with ductus venosus, and first rotation adjusts rotation
Perfusion tube is connected by button 307 with the pressure-measuring pipe 4 of measurement 304 upper end of pipe connector, and liquid level rises in graded tube 401, then
Graded tube 401 is connected by rotation of adjustment knob 307 with ductus venosus, the decline of liquid level in graded tube 401, when liquid level no longer under
It is read on the altitude scale label 402 in 401 outside of graded tube when drop, and reading value can directly be determined by liquid level
In which interval range of high-low pressure label 403, after measurement, rotation of adjustment knob 307 is by perfusion tube and ductus venosus phase
Connection, infusion pipeline carry out infusion work.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
