Detailed description of the invention
Below, the peripherally inserted central catheter in conjunction with-8 pairs of utility models of Fig. 1 is described in detail.
Peripherally inserted central catheter of the present utility model, it includes tube for transfusion 22 and flush pipe 23.
Tube for transfusion 22 is used for transmitting medicine, and tube for transfusion 22 front end is formed with otch 30, to be exported by medicine.Rinse
Pipe 23 is used for transmitting flushing liquor；Flush pipe 23 is provided at predetermined intervals at tube for transfusion 22 around tube for transfusion 22
Outside.At least one joint-cutting 21 it is formed with on the wall of flush pipe 23；Joint-cutting 21 is in the effect of internal pressure
Under open so that flushing liquor is outside and rinse peripheral vein and insert by the internal flush pipe 23 that is flushed to of flush pipe 23
The periphery of central venous catheter.The front end of flush pipe 23 is connected to the outside of tube for transfusion 22 so that flush pipe
23 the most whole covering tube for transfusions 22；Flush pipe 23 at least covers the 2/3 of tube for transfusion 22 total length.Preferably,
Joint-cutting 21 is 3 or more than 3, lays respectively at the upper, middle and lower of flush pipe 23.
The otch 30 of tube for transfusion 22 uses three-dimensional valve structure.The joint-cutting 21 of flush pipe 23 uses valve to tie
Structure.
The otch 30 of tube for transfusion 22 not drawing blood, not infusion medicine time be in natural enclosing state, effectively
Control blood backflow；When medical personnel draw blood, the inner chamber of tube for transfusion 22 forms negative pressure, otch 30
Open owing to negative pressure can concave, so that blood enters tube for transfusion 22.At medical personnel's infusion medicine
Time, the inner chamber of tube for transfusion 22 forms malleation, and otch 30 is due to malleation meeting convex, and medicinal liquid is smoothly via cutting
Mouth 30 flows out.When irrigating catheter, flushing liquor (preferably normal saline or distilled water for injection) is at pressure
Open the joint-cutting 21 of flush pipe 23 under effect and wash away embedding peripheral veins into central veins via joint-cutting 21 outflow
The outer wall (the namely outer wall of flush pipe 23) of conduit and blood vessel wall, stop platelet adhesion, anti-tampon
Formed.After pressure removes, joint-cutting 21 closes automatically, prevents blood back flow.
Breeches joint 10 includes that flush-through connection and infusion connector, flush-through connection connect with flush pipe 23, transfusion
Joint connects with tube for transfusion 22.Breeches joint 10 specifically include rinse seat 11, transfusion seat 15, pad 12,
Glue valve 13, glue valve liner 14, flushing needle tubing 16, Transfusion needle pipe 17.By rinsing needle tubing 16 and transfusion needle
Flush pipe 23 and tube for transfusion 22 are connected on Y type infusion connector by pipe 17.Pad 12, glue valve 13, glue
Valve liner 14 is the usual structure of forward joint, and pad 12 and glue valve liner 14 form direct draught and just can open
The joint-cutting opened；Merely just use for reference in this utility model, in case Hemostatic Oral Liquid is by flush pipe 22 adverse current.
Breeches joint 10 can also be to be integrally formed with tube for transfusion 22 and flush pipe 23.Now, Transfusion needle pipe
16 parts being formed as tube for transfusion 22, rinse needle tubing 17 and are formed as a part for flush pipe 23.
The otch 30 of tube for transfusion 22, it is preferably normal to the outer surface of tube for transfusion 22 and cuts cutting of formation
Seam.Tube for transfusion 22 intrinsic pressure more than external pressure time, i.e. output medicine time, otch 30 is outwardly and opens.Defeated
The external pressure of liquid pipe 22 is more than time intrinsic pressure, and when i.e. drawing blood, otch 30 caves inward and opens.In naturalness
Under, otch 30 is closed.
The joint-cutting 21 of flush pipe 23, it can be similar to otch 30 and be perpendicular to the outer surface of flush pipe and formed,
As shown in Fig. 6 a, Fig. 6 b.Can also be as shown in Fig. 7 a, Fig. 7 b, the oblique formation of joint-cutting 21, i.e. joint-cutting
21 is at an acute angle with the longitudinal vertical plane of flush pipe 23, or with the outer tangent plane of flush pipe 23 in less than 90 °
Angle.Joint-cutting 21 can be linear, it is also possible to is arc line type or wave line style.Cutting of oblique formation
Seam 21 is conducive to the flushing liquor gone out to form the eddy current of the outer wall around peripherally inserted central catheter,
Be conducive to removing the thrombosis deposit of pipe outer wall.
Joint-cutting 21 can be to be formed along the longitudinal axis being parallel to flush pipe 23 of flush pipe 23,
As shown in Figure 5 a, it is also possible to be to be predetermined angular relative to the longitudinal axis of flush pipe 23, such as 5 °,
10°、15°、20°、25°、30°、35°、40°、45°。
Forming the situation of multiple joint-cuttings 21, the longitudinal axis of each joint-cutting 21 and flush pipe 23 in
Angle can be identical, it is also possible to is to differ.
General syringe or flusher can be connected as flushing liquor injection device on flush-through connection, it is possible to
To connect special syringe.This special syringe includes piston head 43, piston rod 44, handle 46.Live
Chock plug 43 is provided with ultrasonic transducer 42 in its bottom, to produce ultrasound wave.Ultrasonic transducer 42
Electric connection line 45 extends to outside via the inside of piston rod 44.Handle 46 shape has the hollow bulb of depression,
In the hollow bulb of the depression that switch 48 is arranged on handle.The opening 47 of the hollow bulb of depression is used for so that using
Person can have access to switch 48.Switch 48 is preferably button type switches.It is arranged in depressed part and is conducive to preventing
Only maloperation.The joint 41 of syringe is for being connected with flush-through connection.Ultrasonic transducer 42 is common
Electronic installation, its principle and function are not repeating.
When using above-mentioned special syringe, flushing liquor pours under pressure in blood vessel, rinses simultaneously
Liquid is also loaded with ultrasound wave, utilizes the effect of ultrasound wave to be carried out, be obviously enhanced elimination effect.
During use, it is possible to use flusher is lasting, discontinuously or be periodically rinsed, it is to avoid blood is tangible
Composition adheres to, it is to avoid the formation of thrombosis.
