Abstract
The utility model provides a blood collection adapting tube for hematodialysis, and relates to the technical field of medical apparatus and instruments. The blood collection adapting tube for the hematodialysis comprises a thick tube. One end of the thick tube is provided with a connecting tube which can be inserted into the open end of a hematodialysis blood collecting needle, and the other end of the thick tube is provided with a needle head. The blood collection adapting tube for the hematodialysis is characterized in that an adapter ring capable of being connected with the open end of the hematodialysis blood collecting needle is arranged between the thick tube and the connecting tube, an elastic needle membrane is sleeved on the needle head, and a needle membrane cover is sleeved outside the needle membrane. According to the blood collection adapting tube for the hematodialysis, when blood collection is finished, the needle head which discharges blood is pulled out of a test tube provided with rubber, the needle head returns to the inside of the needle membrane, at the moment, the needle membrane cover is installed, so that blood can be prevented from flowing out.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of blood sampling adapted pipe that is used for hemodialysis.
Background technology
Hemodialysis (Hemodialysis) is called for short hemodialysis, and popular saying also is referred to as artificial kidney, washes kidney, is a kind of of blood purification technology.It utilizes the semipermeable membrane principle, through diffusion, various harmful and unnecessary metabolic wastes and too much electrolyte shift out externally in the convection cell, reach the purpose that purifies the blood, and inhales and reaches the purpose of correcting Water-Electrolyte and acid-base balance.In hemodialysis, often get blood through vein, then patient's blood is analyzed.At present, adopt vein blood taking needle to carry out venipuncture clinically, other one of this blood taking needle connects blood letting needle, then blood letting needle is put in vitro, and this test tube has been put into additive before use, and has been pumped into vacuum.But, in the prior art, get in the blood in hemodialysis, exist drawback: because the blood-letting end is negative pressure, when fleams when test tube takes out, blood flows out easily, pollutes medical personnel, causes infection simultaneously easily.
The utility model content
The purpose of this utility model provides a kind of blood sampling adapted pipe that is used for hemodialysis, can avoid in the blood collection procedure, pollutes medical personnel's hands, the approach of blocking-up cross infection.
This utility model provides a kind of blood sampling adapted pipe that is used for hemodialysis; Comprise extra heavy pipe; One end of said extra heavy pipe is provided with the connection tube that can be inserted into hemodialysis blood taking needle opening, and an other end is provided with syringe needle, it is characterized in that being provided with the adapter ring that can be connected with hemodialysis blood taking needle opening between said extra heavy pipe and the connection tube; Be with rubber-like pin film on the said syringe needle, the outside of said pin film is with the pin Membrane cover.
Adopt this utility model to be used for the blood sampling adapted pipe of hemodialysis, when getting the blood agglomeration bundle, after the syringe needle of blood-letting was extracted from the test tube that has rubber, syringe needle had been got back in the pin film, at this moment, the pin Membrane cover was loaded onto, and can avoid blood to flow out.
Description of drawings
Fig. 1 is the structure diagram of this utility model, 1-connection tube wherein, 2-adapter ring, 3-extra heavy pipe, 5-pin Membrane cover, 6-syringe needle, 7-pin film.
The specific embodiment
The concrete structure of embodiment 1 this utility model
The blood sampling adapted pipe that is used for hemodialysis that this utility model provides; Comprise extra heavy pipe 3; One end of said extra heavy pipe 3 is provided with the connection tube 1 that can be inserted into hemodialysis blood taking needle opening, and an other end is provided with syringe needle 6, is provided with the adapter ring 2 that can be connected with hemodialysis blood taking needle opening between said extra heavy pipe 3 and the connection tube 1; Be with rubber-like pin film 7 on the said syringe needle 6, the outside of this pin film 7 is with pin Membrane cover 5.
Adapter ring comprises clamping with the connected mode of hemodialysis blood taking needle opening or is threaded, and for example female thread can be set in adapter ring, at hemodialysis blood taking needle opening external screw thread is set, and internal and external threads matches here.
During use, pin Membrane cover 5 is pulled up from the blood sampling adapted pipe that is used for hemodialysis, connection tube 1 is inserted hemodialysis blood taking needle opening; Then; Adapter ring 2 is linked to each other with hemodialysis blood taking needle opening, with the rubber stopper of the syringe needle that is with rubber-like pin film 76 insertion vacuum test tubes, at this moment; Syringe needle 6 is worn out pin film 7 and is got in vitro, and blood gets in the vacuum test tube.When blood sampling finishes, syringe needle 6 is extracted, at this moment, syringe needle 6 gets in the pin film 7, pin Membrane cover 5 is enclosed within on the blood sampling adapted pipe of hemodialysis, can the occlude blood outflow.
