Abstract

The utility model provides a novel arteriovenous puncture needle for dialysis, which belongs to the field of medical instruments and comprises a needle head, needle wings, a blood collection tube and a connector, wherein the side wall of the blood collection tube is provided with a second blood collection tube communicated with the side wall of the blood collection tube; the blood collecting tube II can enable the extracorporal circulatory blood to continue circulating, greatly reduces the time for stopping the blood pump, prevents the blood coagulation phenomenon of the dialyzer and the dialysis pipeline caused by the stop of the blood pump, gains precious time for preparing new puncture, and is beneficial to protecting the life safety of patients.

Description

Novel arteriovenous puncture needle that dialysis was used

Technical Field

The utility model relates to the field of medical instruments, in particular to a novel arteriovenous puncture needle for dialysis.

Background

At present, when dialysis puncture nursing is carried out on a patient, two disposable arteriovenous puncture needles are needed to be used for blood circulation; when a nursing staff has puncture errors or one of an artery and a vein fails in a dialysis process, the puncture needle needs to be punctured again, blood at the moment circulates outside the body, the blood pump needs to be stopped for a long time, and after the blood pump is stopped for a long time, a dialyzer and a dialysis pipeline can be coagulated, so that the risk of endangering the life safety of a patient is caused.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical defects, the utility model aims to provide a novel arteriovenous puncture needle for dialysis, which solves the problems that a blood pump needs to be stopped for a long time, and a dialyzer and a dialysis pipeline can generate blood coagulation, so that the life safety of a patient can be endangered.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides a novel sound arteries and veins pjncture needle that dialysis was used, includes syringe needle, needle wing, heparin tube, connector, be equipped with a No. two heparin tubes rather than being linked together on the lateral wall of heparin tube, still be equipped with a clip on the heparin tube, just the clip is located No. two heparin tubes with between the connector, be equipped with a No. two clips on No. two heparin tubes, No. two terminal of heparin tube still is equipped with a No. two connectors.

The utility model has the beneficial effects that: this design can let extracorporeal circulation's blood continue to circulate through No. two heparin tubes, the time that the blood pump that has significantly reduced stopped for dialyzer and dialysis tubing can not take place the phenomenon of blood coagulation, also win the valuable time for preparing new puncture simultaneously, are favorable to protecting patient's life safety.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is a schematic structural diagram of a novel arteriovenous puncture needle for dialysis provided by an embodiment of the present invention.

Description of reference numerals:

the blood collection tube comprises a needle head 1, a needle wing 2, a blood collection tube 3, a clamp 4, a connector 5, a blood collection tube 6, a connector 7 and a clamp 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figure 1, a dialysis uses the new arteriovenous puncture needle, including syringe needle 1, the needle wing 2, the blood taking tube 3, connector 5, the connector 5 is used for connecting the dialysis pipeline, there is a number two blood taking tube 6 communicated with it on the sidewall of the blood taking tube 3, is used in when the puncture is lost, connect the pipeline that the puncture needle of mistake corresponds to, thus can let the blood of extracorporeal circulation continue to circulate, make blood pump, dialyzer, dialysis pipeline will not take place the phenomenon of blood coagulation, win the precious time for preparing new puncture at the same time, help to protect patient's life safety, still have a clamp 4 on the blood taking tube 6, and the clamp 4 locates between number two blood taking tube 6 and connector 5, the clamp 4 is used for controlling the flowrate of the liquid in the blood taking tube 6, there is a number two clamp 8 on the number two blood taking tube 6, is used for controlling the flowrate of the liquid in the number two blood taking tube 6, no. two heparin tube 6's end still is equipped with a No. two connector 7 for the use of high-speed joint dialysis pipeline.

During the use, when puncture error appears, take off the dialysis pipeline that the error pjncture needle corresponds to be connected this pipeline through No. two connectors and No. two heparin tubes, blood can continue to circulate between heparin tube, dialysis pipeline, No. two heparin tubes and flow, makes the dialysis pipeline can not take place the phenomenon of blood coagulation, wait to insert behind the new pjncture needle with the pipeline reconnection can.

The blood collecting tube II is designed to enable extracorporeal blood to continuously flow in a circulating manner, so that the time for stopping the blood pump is greatly shortened, the phenomenon of blood coagulation of a dialyzer and a dialysis pipeline is avoided, precious time is saved for preparing new puncture, and the life safety of a patient is protected.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.

Claims

1.
