Description
Technical field
The present invention relates to the field of structural design of medical supplies, more particularly to a kind of double sacculus remaining needles.
Background technology
Remaining needle is the conventional medical apparatus in nursery work, have it is easy to use, reduce to patient puncture number effect,
Punctured repeatedly during so as to decrease clinical transfusion, reduce the puncture pain of patient and the workload of clinical nursing staff,
Therefore, obtained a wide range of applications in current clinic.
In existing remaining needle, generally comprise：Puncture needle, indwelling needle tubing and transfusion catheter.In use, it will puncture first
Pin UNICOM indwelling needle tubing inserts the injection position of patient together, and indwelling needle tubing then is imported into patient's blood by puncturing needle guide
Pipe, puncture needle is finally extracted out, indwelling needle tubing is stayed in patient vessel, and fixed with application pad pasting.In use, pass through transfusion
Conduit liquid medicine injection into patient vessel.
However, existing indwelling needle tubing is retained in patient vessel, during stopping infusing, it is very easy to occur in needle tubing
The situation of Blood occlusion because of blood penetration, once the situation of Blood occlusion occurs, it is necessary to re-replace indwelling needle tubing, be pre-
Occur Blood occlusion phenomenon in anti-indwelling tube to be often injected into by three-way pipe using the heparin solution or physiological saline of dilution
Carry out tube sealing in indwelling needle tubing, it is relatively complicated in operation, and the effect of pre- preventing thrombosis also having time limitation, generally every 6~8
Hour just needs washing pipe tube sealing again.In addition, when re-starting transfusion, it is also necessary to using syringe pumpback blood, to judge that pipeline is
It is no unobstructed.These not only increase the operation of nurse, also increase the pain of patient.
The content of the invention
For above-mentioned problem, the present invention provides a kind of double sacculus remaining needles, can realize automatic washing pipe, automatic sealing package
Pipe, automatic pumpback blood, cause patient safety hidden to overcome remaining needle of the prior art easily to occur Blood occlusion when in use
The problem of trouble, nurse operation trouble and increase patient's pain, there is blood in the indwelling needle tubing of indwelling so as to both avoid
The situation of embolism occurs, and in turn simplify operation, without tube sealing and pumpback blood, both adds patient safety, mitigate the pain of patient
Hardship, it also simplify nurse operation.
To achieve these goals, the technical scheme taken of the present invention is：
A kind of double sacculus remaining needles, including puncture needle, indwelling needle tubing, transfusion catheter, infusion tee and closing clip, it is described
Remaining needle pipe sleeve is located at the puncture needle, and the transfusion catheter connects with the indwelling needle tubing, the infusion tee with it is described defeated
Fluid catheter is connected, and the closing clip is arranged on the transfusion catheter, wherein, in addition to epicoele sacculus and cavity of resorption sacculus, it is described
Epicoele sacculus connects with the transfusion catheter, and the epicoele sacculus and the cavity of resorption sacculus separate the transfusion catheter, under described
This section of transfusion catheter between chamber sacculus and the indwelling needle tubing is the first transfusion catheter；
There is tamper catheter channel in the catheter wall of first transfusion catheter, have in the needle wall of the indwelling needle tubing
There is tamper needle channel, the cavity of resorption sacculus connects with the tamper catheter channel, the tamper catheter channel and institute
State the connection of tamper needle channel；
Elastomeric bladder, the elastomeric bladder and the tamper needle channel are provided with the inside of the mouth of pipe end of the indwelling needle tubing
Connection, when the elastomeric bladder is in swelling state, the elastomeric bladder can block the mouth of pipe end of the indwelling needle tubing；
Wherein, under original state, in the cavity of resorption sacculus, the tamper catheter channel and the tamper needle channel
It is respectively provided with air or safe liquid.
Above-mentioned double sacculus remaining needles, wherein, this section of transfusion catheter between the epicoele sacculus and the infusion tee
For the second transfusion catheter, the closing clip is arranged on second transfusion catheter.
Above-mentioned double sacculus remaining needles, wherein, the volume of the cavity of resorption sacculus is more than or equal to the elastomeric bladder and is in expansion
Volume during state.
Above-mentioned double sacculus remaining needles, wherein, the elastomeric bladder is ring-type.
Above-mentioned double sacculus remaining needles, wherein, the volume of the epicoele sacculus is more than the volume of indwelling needle tubing tube chamber.
Above-mentioned technical proposal has the following advantages that or beneficial effect：
Double sacculus remaining needles provided by the invention in liquid-transport pipe-line by setting epicoele sacculus and cavity of resorption sacculus, in indwelling
Elastomeric bladder is set on the inside of needle tubing mouth of pipe end.Epicoele sacculus communicates with transfusion catheter.Air or safe liquid are filled in cavity of resorption sacculus
Body, and communicated with elastomeric bladder.When suspending transfusion, closing clip only need to be closed.Closing clip is oppressed first closes the of top
Two transfusion catheters, automatic washing pipe will be realized in the transfusion push-in indwelling needle tubing in the epicoele sacculus by secondly oppressing epicoele sacculus, most
Compressing cavity of resorption sacculus makes elastomeric bladder bulging and closes indwelling needle tubing afterwards.When infusing again, closing clip only need to be opened.Cavity of resorption
Sacculus resilience opens indwelling needle tubing, and epicoele sacculus resilience makes blood flow into remaining needle pipe and the first transfusion catheter, realizes automatic
Pumpback blood.Invention not only simplifies operation, mitigates patient's pain, reduces nurse job amount, and thoroughly solve remaining needle
Easily there is the situation of Blood occlusion, improve the safety of patient.
