Description
Technical field
The utility model belongs to medical aid device technical field, and in particular to a kind of for filtering the device of thrombus.
Background technique
Usually in hospital, for urgent patient especially ICU patient, it is often necessary to from arterial line or venous line
Upper extraction blood preparation.However, either still extracting from venous line from arterial line, 4~5ml liquid will be first extracted
Then body leaves and takes blood preparation again, this 4~5ml liquid is clinically to abandon because suspecting there is blood clot.Specifically,
Extracting blood preparation by the road in clinic at present has following three kinds of methods:
(1) arteriopuncture pipe connects energy converter, and the triple valve for being then directly over energy converter front end is first out of arterial line
It extracts 4-5ml blood and abandons, then leave and take blood preparation again.For this method, due to needing gas of repeatedly drawing blood daily, if suffering from
If person moves in ICU time length, it is bound to cause patient's obviously excessive blood loss, still, if this 4-5ml blood does not abandon, to trouble
Person pushes back, and embolus that may be present will be promoted in blood vessel, to cause serious injury to patient.
(2) arteriopuncture pipe connects energy converter, is then again coupled to after the side of its triple valve connects pressure extension tube
Another triple valve, then with syringe at the triple valve being again coupled to pumpback 4-5ml liquid, do not have in general syringe at this time
Blood；Blood preparation is left and taken at the triple valve of energy converter later, finally with the salt water flushing pipeline of connection.For this side
Method, but does not guarantee that whether there is or not thrombus feedbacks in blood, can bring certain positions to occur although not wasting blood to ICU patient
The hidden danger of embolism.
(3) 4-5ml blood is first extracted out of central vein pipeline to abandon, then leave and take blood preparation.This method can also be made
At the obvious blood loss of patient, if not abandoning 4-5ml blood, can also there be above-mentioned risk.
Moreover, current medical three-way valve also be three simple accesses, there is no filter thrombus function, clinic in
Also without there is the attachment device comprising thrombus filtering function.

Interface 11 is connect with physiology salt water end (W.E.) 5, and control switch 7 is arranged on the pipeline between physiology salt water end (W.E.) and first interface 11,
And control switch 7 is placed in off, wherein control switch 7 can preferably realize the construction of switch of opening and closing by pulling；
(2) connection patient end and third interface 13 are inserted into 5ml syringe after the calparine cap disinfection on filter 3, and
Extract blood of the 4-5ml by filtering；
(3) pintle for separating 5ml syringe, connects 10ml syringe (or 1ml syringe), extracts suitable blood mark
This；
(4) regulating three-way valve core is to close second interface 12, and the 4th interface 14, second interface 12 and patient end are connected
It is logical；After the calparine cap disinfection to the 4th interface 14, the blood in 5ml syringe is refilled in patient body；
(5) regulating three-way valve core is to close third interface 13, and is connected to first interface 11, second interface 12, then pulls open
Control switch 7 utilizes normal saline flushing pipeline (pipeline for being equipped with filter 3 wouldn't rinse)；
(6) regulating three-way valve core is filtered the flushing of device 3 to close second interface 12, i.e., is connected to 5ml syringe
On the calparine cap of filter 3, if having thrombus in filtering inner bag 32, salt water is pumped full using 5ml syringe, then unscrews filter
3 and third interface 13 junction, utilize salt water in 5ml syringe to rinse thrombus；The process can operate repeatedly, until by blood
After bolt is rinsed well, then filter 3 is connected to third interface 13, for subsequent use.
The working principle of the device for filtering thrombus in embodiment 2 can be found in the working principle of embodiment 1, different
It is that without the syringe of pintle used in the present embodiment, therefore pintle lock out operation need not be carried out when replacing syringe.
Other contents of the device for filtering thrombus of the utility model are referring to the prior art, and details are not described herein.
More than, it is only the preferred embodiment of the utility model, limit in any form not is made to the utility model
System, thus it is all without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above embodiments institute
Any modification, equivalent variations and the modification made, are still within the scope of the technical solutions of the present invention.
