Description

Arteriovenous internal fistula pjncture needle with fixed function

Technical Field

The utility model relates to a medical treatment pjncture needle field especially relates to an arteriovenous internal fistula pjncture needle with fixed function.

Background

Hemodialysis patient will establish the extrinsic cycle, carries out hemodialysis treatment, and the nurse just will use the pjncture needle to draw forth and reinfuse blood in patient's internal arteriovenous fistula blood vessel department, and the dialysis time is 4 hours usually, and the fixed of internal fistula pjncture needle is very important, if fixed not properly, appears patient's blood easily and flows out, causes the medical malpractice. The existing arteriovenous internal fistula puncture needle needs to be fixed by an additional medical adhesive tape, is complex in fixing process, needs to spend a large amount of time for fixing, and is not fixed well and easy to slide out.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at is not enough to prior art, provides an arteriovenous internal fistula pjncture needle with fixed function to the fixed process of the arteriovenous internal fistula pjncture needle that exists is loaded down with trivial details among the solution prior art, and fixed with long and fixed not easy roll-off's problem well.

The purpose of the utility model is realized through the following technical scheme: the utility model provides an arteriovenous internal fistula pjncture needle with fixed function, includes needle body, needle handle, connecting pipe and applies ointment or plaster, the needle handle is oval, one end fixed connection needle body, other end and connecting pipe fixed connection, apply ointment or plaster and be located the junction of connecting pipe and needle handle, be located needle handle top, link to each other with the connecting pipe through the adhesive tape, the adhesive tape middle part glues in the connecting pipe below, walks around the connecting pipe, and the cross fixation is applied ointment or plaster above the needle handle.

Further, the needle body is stainless steel hollow needle tube, the connecting pipe is the PVC material hose.

Furthermore, the long axis of the elliptic needle handle is 5cm, the short axis is 2cm, and the elliptic needle handle is made of PVC material.

Furthermore, the adhesive tapes are fixed above the needle handle in a crossed manner and extend to the position, close to the needle body end, of the application tape and are hidden below the application tape when 2cm is remained.

Furthermore, the application is rectangular, and a square medical gauze with the length of 3cm and the width of 3cm is arranged in the middle.

The utility model has the advantages that: due to the adoption of the design of the needle handle and the application, the fixing flow of the arteriovenous internal fistula puncture needle is simplified, the arteriovenous internal fistula puncture needle is not easy to slip, the fixing time is shortened, and the working efficiency of nursing personnel is improved.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in figures 1-4, the utility model provides an arteriovenous internal fistula pjncture needle with fixed function, including needle body 1, needle handle 2, connecting pipe 4 and application 3, the utility model discloses the improved position lies in needle handle 2 and application 3, and current needle handle length 4cm, wide 1.5cm, PVC (polyvinyl chloride) material, current arteriovenous internal fistula pjncture needle do not have the application. The utility model discloses well needle handle 2 is oval, one end fixed connection needle body 1, the other end and 4 fixed connection of connecting pipe, oval needle handle 2 reduces convenient operation with adjacent applying ointment or plaster 3 mutual interference when the operation. The application 3 is positioned at the joint of the connecting pipe 4 and the needle handle 2, positioned above the needle handle 2 and connected with the connecting pipe 4 through the adhesive tape 5, the middle part of the adhesive tape 5 is adhered below the connecting pipe 4, bypasses the connecting pipe 4, is fixed on the application 3 above the needle handle in a crossed manner and extends to the position, close to the end of the needle body 1, of the application 3, and is hidden below the application 3 when 2cm is remained. After the puncture is finished, the application 3 can be turned over to be pasted and fixed, and the fixing work is finished. And the crossed fixing structure of the adhesive plaster 5 plays a role of longitudinal reinforcement in the fixation of the application 3 so as to prevent the puncture needle from sliding out of the body when the connecting pipe 4 is pulled. The application 3 is a rectangle with the length of 10cm and the width of 6cm, and the middle part is provided with a square medical gauze 6 with the length of 3cm and the width of 3 cm. The rectangular patch plays a main fixing role for the arteriovenous internal fistula puncture needle. The square medical gauze has the functions of protecting the puncture wound and absorbing the exuded blood.

The needle body 1 is a stainless steel hollow needle tube, and the connecting tube 4 is a PVC (polyvinyl chloride) material hose. The long axis of the elliptic needle handle 2 is 5cm, the short axis thereof is 2cm, and the elliptic needle handle is made of PVC (polyvinyl chloride).

Before use, the arteriovenous internal fistula puncture needle with the fixing function provided by the utility model is in the state shown in figures 1 and 2, and the application paste is folded over the connecting pipe by 180 degrees; when the puncture patch is used on a patient, the schematic diagrams are shown in fig. 3 and 4, and after puncture is completed, the patch can be turned over by 180 degrees for pasting and fixing, so that fixing work is completed.

The above-mentioned embodiments are provided for explaining the present invention, not for limiting the present invention, and any modifications and changes made to the present invention are within the spirit of the present invention and the scope of the claims and fall within the scope of the present invention.
