Description

Dialysis blood taking needle

Technical Field

The utility model relates to the technical field of medical equipment, more specifically are blood taking needles for dialysis.

Background

A venous blood lancet is a blood lancet used for collecting blood samples during medical examination. The blood taking needle at the top end is used for puncturing a blood vessel, the tail end transparent hose is connected with the tail needle, the tail needle is wrapped by the rubber hose, and the needle cap is sleeved outside the tail needle and used for puncturing a vacuum blood taking test tube and sucking blood into the tube by using negative pressure in the test tube.

The collection method of biochemical blood samples of the maintenance hemodialysis patients can be summarized into 2 types. The first method is that the arteriovenous internal fistula is punctured, a 5mL syringe is connected with an arteriovenous puncture needle for drawing blood, and then a needle head of the 5mL syringe is connected to inject the blood of the syringe into a blood collection tube. The method is easy to cause needle stick injury, has large blood sampling amount, is easy to overflow blood when blood is repeatedly drawn, is easy to pollute the collected blood sample, has poor sample amount control and directly influences the test result, and has complex blood sampling procedure and large workload of nurses. And the second method comprises the steps of puncturing an arteriovenous internal fistula, connecting a hemodialysis pipeline to draw blood to an arterial ampule, regulating the rotation speed of a blood pump to 50mL/min, taking blood at a rubber plug of an arterial segment by using a 5mL syringe, and injecting the blood of the syringe into a blood collection tube. The method needs disinfection, is not easy to insert the needle into the rubber plug once, is easy to cause needle stick injury, needs repeated blood drawing when the blood collection amount is large, is easy to pollute the collected blood sample, has the direct influence on the test result because the sample amount is not easy to grasp, and has complex blood collection procedure and large workload of nurses. For this reason, a new scheme needs to be designed to give improvements.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dialysis blood taking needle has solved prior art and has easily taken place the needle stick in the blood sampling and hinder, blood easily spills over, the easy pollution of blood sample of gathering when the big repetition of the volume of taking a blood sample is taken a blood sample, and the sample volume is not good to be held direct influence inspection result, and the blood sampling procedure is complicated, the technical problem that nurse's work load is big.

In order to achieve the above object, the utility model provides a following technical scheme: a dialysis lancet comprising: joint, transparent hose, flexible rubber hose and tail needle, the one end of transparent hose is connected at the end of joint, the other end and is connected with flexible rubber hose, the tail needle is connected at flexible rubber hose's end, the left side of joint is provided with the spread groove, the middle part level of spread groove is provided with the pipe, it is provided with the screw thread to surround on the inner wall of spread groove.

As a preferred embodiment of the present invention, a thread groove is formed on the inner wall of the connecting groove through a thread, and a convex strip is provided on the surface level of the thread groove at the end.

As a preferred embodiment of the utility model, evenly be provided with a plurality of antislip strip on the outer wall that connects, screw thread, pipe, sand grip and antislip strip all with connect integrated into one piece.

As a preferred embodiment of the utility model, the guide hole that communicates with the transparent hose inside is seted up at the middle part of pipe.

As a preferred embodiment of the present invention, a needle cap is sleeved outside the tail needle.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses, with the joint that has the spiral bayonet socket in the blood taking needle replacement for, directly with internal arteriovenous fistula pjncture needle or dark ductus venosus joint, realized the closed blood sampling, keep the vacuum negative pressure of blood sampling test tube, automatic negative pressure attracts the blood sampling. Compared with the traditional blood sampling method, the blood sampling method simplifies the complicated blood sampling step flow, directly saves the blood sampling time, reduces the occurrence of needle stick injury, improves the working efficiency of blood sample collection, has simple structure, is easy for batch production, and is worthy of popularization.
