Traditional extraction for PRP needs to use two times centrifugal method, two times centrifugal method needs two centrifuge tubes, namely containing the centrifuge tube of sodium citrate anticoagulant with not containing the centrifuge tube of antithrombotics, at the surgical application that some PRP usage quantitys are less, the such as treatment etc. of some orthopaedic diseases, such operating method expends time in length, operation steps is many, operating process easily makes mistakes, the extraction containing thrombocyte plasma is also insufficient, or suck the blood plasma containing red corpuscle thus cause pollution to a certain degree.
In view of this, the embodiment of the present application provides a kind of double-jacket tube centrifugation injection device, it is possible to convenient and simple realizes the extraction to PRP, and this double-jacket tube centrifugation injection device comprises: outer tube 100 and inner sleeve 200.
Described outer tube 100 comprises urceolus 101 and outer piston 102, the first port 103 has been offered in one end of described urceolus 101, described urceolus 101 is provided with the first projection 104 near the inside of described first port 103, described first projection 104 inside is provided with and the connecting passage 105 that described first port 103 is connected, the other end of described urceolus 101 is open, can hold described inner sleeve 200.
The outer piston 102 that described urceolus 101 inside is also provided with described first projection 104 phase is mated, described outer piston 102 is provided with the first connection section 106 away from the one side of described first projection 104, described first connection section 106 is arranged on described outer piston 102 apart from described first projection 104 position the farthest away, and described outer piston about 102 is connected by described first connection section 106.
Outer tube 100 and inner sleeve 200 match and can realize the extraction to PRP, the first port 103 that urceolus 101 is offered can be used for extracting blood, connecting needle on the first port 103, can extract vein whole blood by this syringe needle from human body, for follow-up centrifugal extraction is prepared. The outer piston 102 of urceolus 101 inside mates with the first projection 104 phase, if namely the first projection 104 is cone, the shape of so outer piston 102 is exactly taper so that outer piston 102 can be fitted in the first projection 104 completely. First projection 104 is to urceolus 101 inside protrusions, and the first port 103 is connected by the connecting passage 105 that the first projection 104 inside is arranged with urceolus 101 inside, when carrying out the extraction of blood, blood can flow through connecting passage 105 by the first port 103 and be flowed into urceolus 101 inside.
The diameter of described inner sleeve 200 is less than the diameter of described outer tube 100, and described inner sleeve 200 comprises interior cylinder 201, push rod 202 and interior piston 203. Two-port netwerk 204 has been offered in one end of described interior cylinder 201, it is inner that described push rod 202 and interior piston 203 are arranged on described interior cylinder 201, one end of described push rod 202 is connected with described interior piston 203, and described Two-port netwerk 204 can coordinate with described first connection section 106 spiral.
Outer piston 102 is provided with the first connection section 106 away from the one side of described first projection 104, can connect to get up by outer piston 102 and inner sleeve by this first connection section 106, after inner sleeve connects to get up by the first connection section 106 and outer piston 102, by taking out the motion drawing whole outer sleeve just can control outer piston 102. When the extraction of blood, inner sleeve is connected with outer piston 102 by the first connection section 106, draw whole inner sleeve that outer piston 102 is detached urceolus 101 by taking out, make to form negative pressure space between outer piston 102 and the first port 103, blood is drawn in urceolus 101, the blood now extracted is whole blood, and extraction action now is control whole inner sleeve motion, and the push rod 202 of inner sleeve inside is geo-stationary with the mutually internal cylinder 201 of interior piston 203.
Two-port netwerk 204 has been offered in one end of interior cylinder 201, can be connected with the first connection section 106 on outer piston 102 by this Two-port netwerk 204, the connection of spiral form can be adopted between the two, when needs connect, control inner sleeve rotates, inner sleeve is connected with outer piston 102, and after both connections are got up, sealing can be realized, namely the liquid such as blood can not be omitted by the junction of Two-port netwerk 204 and the first connection section 106, interior cylinder 201 can only be entered into by Two-port netwerk 204, ensure the normal of PRP leaching process.
When using above-mentioned double-jacket tube centrifugation injection device, first inner sleeve is connected with the first connection section 106 on outer piston 102 by Two-port netwerk 204, being pushed into by outer piston 102 and the laminating as far as possible of the first projection 104, now the interior piston 203 on inner sleeve is also pushed into position immediate with Two-port netwerk 204 in interior cylinder 201 by push rod 202.
Then connecting needle on the first port 103, blood directly can be extracted from human vas by this syringe needle, other connecting hose can also be used to extract blood from blood vessel, or use syringe needle to extract blood from other blood storage devices, now carry out the extraction of blood, be by controlling interior cylinder 201, pull outer piston 102, making blood enter into urceolus 101, internally cylinder 201 is static mutually with piston for the push rod 202 in interior cylinder 201, and blood does not enter into interior cylinder 201.
The content of the blood extracted can be determined according to practical situation, after using double-jacket tube centrifugation injection device that blood draw is entered urceolus 101, the syringe needle being connected on the first port 103 is taken off, seal cap is installed outside the first port, prevent blood from spilling, again whole double-jacket tube centrifugation injection device is put into centrifugation apparatus carries out centrifugal, the setting of concrete centrifugal parameter can be determined according to practical situation, double-jacket tube centrifugation injection device generally vertical placement time centrifugal, first port 103 is in lower section, and inner sleeve 200 is in top.
Use the double-jacket tube centrifugation injection device in the embodiment of the present application, general is all extract vein whole blood, vein whole blood is after the completed centrifugation, just divide into containing thrombocyte plasma with containing red corpuscle blood plasma, wherein containing thrombocyte plasma near outer piston 102, and containing the blood plasma of red corpuscle away from outer piston 102, be the blood plasma that treatment needs containing thrombocyte plasma. Now, moved near the direction of the first port 103 by cylinder 201 in control inner sleeve 200, promote to the direction of the first port 103 by outer piston 102, simultaneously, pull the push rod 202 in interior cylinder 201, push rod 202 is pulled to the direction away from Two-port netwerk 204, so that it may with by being drawn in interior cylinder 201 by the first connection section 106, Two-port netwerk 204 containing thrombocyte plasma in urceolus 101.
