Description
Technical field
It is more particularly to a kind of to turn back dystopy and transfusion port for replying PICC veins the invention belongs to field of medical device
The pen type vein of dystopy blocks instrument.
Background technology
Peripherally Inserted Central Catheter (peripherally inserted central catheter,
PICC)：Through peripheral vein (such as：Basilic vein, median basilic vein, cephalic vein etc.) merging central venous catheter, catheter tip position
Under superior vena cava 1/3 with atrium dextrum junction, i.e., at right auricle of heart.Suitable for medium-term and long-term venous transfusion, chemotherapy of tumors, parenteral battalion
It supports, gerontal patient's infusion.Start the U.S. the 1990s just B ultrasound guiding is introduced into PICC with reference to Sai Dingge technologies and is put in pipe,
It clinically mostly carries out putting pipe using the technology at present.But put during pipe due to anatomical variation or patient body position's cooperation it is not in place with
And the reasons such as operation technique, it frequently can lead to PICC head end dystopys.Misplacement is that PICC puts the most common complication of pipe, document
Report that its catheter tip dystopy rate may be up to 34.2%.Misplacement can increase fluid seepage, lead to local limb swelling, vein
The generation of the complication such as inflammation, catheter blockage, phlebothrombosis, pain, can also result in cannot complete to treat and discarded conduit, need sometimes
Again pipe is put.
PICC misplacements are most common in jugular vein with dystopy.Since cephalic vein punctures, position is not set, and it is too shallow to put pipe
(as to change of the epimere through position of cephalic vein or superior vena cava, Trendelenburg position, firmly cough can dystopy cephalic vein) reason
Conduit is caused to enter jugular vein.PICC be it is blind wear, individual blood vessel is ever-changing, and it is inevitable misplacement occur.It is different to there is conduit
How key is treated as behind position.Typically now for jugular vein dystopy, such as enter length not deeply, patient is allowed to do jump dynamic more
Make or walk stair from top to bottom, conduit is made to be back to innominate vein by gravity principle；If it is pulled out into being used during length depth
The method that conduit send conduit to shoulder position with side trimming.
Complete vein implanted transfusion port (totally implantable venous access ports, TIVP) is
It is a kind of be fully implanted in it is subcutaneous, for the venous device in long-time indwelling body, be applicable to prolonged and repeated venipuncture, change
The patient for the treatment of, Nutritional support and blood transfusion.At present, clinically used implantation approach is the wall of the chest infusion through subclavian vein
Port and the arm transfusion port being implanted into through peripheral blood vessel such as arm basilic vein, brachial vein and median vein, also can there are neck and
The situation of oxter dystopy.
Therefore there is an urgent need for can make the equipment of homing after the conduit of embedment vein or transfusion port dystopy.
Invention content
The purpose of the present invention is in view of the drawbacks of the prior art, provide a kind of conduit or transfusion port that can make embedment vein
The pen type vein of homing blocks instrument after dystopy.
To achieve these goals, the present invention uses following technical scheme：A kind of pen type vein blocks instrument, including：Scanning
Probe, outer shell, controller, liquid crystal display, battery pack and control switch；Before wherein described scanning head is arranged on outer shell
End, scanning head surface are provided with pressure sensor, and the pressure sensor is used to detect pressure letter of the scanning head to skin
Number and send controller to, ultrasonic transducer is provided in scanning head, the ultrasonic transducer sends out ultrasonic wave, and acceptor
The echo signal of body reflection simultaneously sends controller to, and the pressure signal received and echo signal are converted into pressure by the controller
Force value and ultrasonoscopy are simultaneously shown on liquid crystal display；The liquid crystal display is arranged on the outer surface on outer shell top, and control switch is set
It puts on the top of outer shell, the control switch is for Switching Power Supply and is configured；Pressure sensor, ultrasonic transducer,
Connection is arranged on the controller inside outer shell respectively for liquid crystal display and control switch, and the battery pack is arranged in outer shell and connects
Connect controller.
The scanning head is the cylinder that cross section is ellipse, and front end is in arc facial protrusion, the long diameter of the ellipse
For 2cm, short a diameter of 1cm.
The outer shell be cross section be ellipse, lower thin and upper thick cylinder, a diameter of 3cm of length of lower section, upper section
The a diameter of 6cm of length.
The outer shell outer surface liquid crystal display lower part is provided with one section of non-slip rubber ring.
Plug-in type liquid crystal display writing pencil is provided at the top of the outer shell.
It is when carrying out PICC or transfusion port puts pipe that the pen type vein of the present invention, which blocks instrument, observes blood vessel situation and prevention is led
To being handled when PICC or transfusion port dystopy when tube neck, oxter or other position angioplanies and using finger pressure method
When use, can not determine the dynamics of pressing and PICC or transfusion port situation due to carrying out pressing with finger.Use pen type vein
Instrument is blocked, the pressure sensor of scanning head outer surface setting to the pressure of vein and passes through controller in liquid for impression probe
Brilliant screen display pressure value, at the same the ultrasonic transducer in popping one's head in by controller in liquid crystal screen display blood vessel blocking or
The situation of dystopy.Using outer shell top set plug-in type liquid crystal display writing pencil can liquid crystal display to ultrasonic transducer into
Row parameter selection.Non-slip rubber ring can contribute to operator and hold blocking instrument.
Structure novel of the present invention, it is easy to use, the low jaw Jugular vessel resistance of finger pressure method cooperation patient's rotary head can used
It is used when disconnected method during neck PICC dystopys to handling, the situation for the observation blood vessel blocking that can assist a physician, and according to need
Suitable pressure to be used to press the vein of blocking, make the conduit position back to normal of dystopy.
