Abstract
The utility model relates to a vein blood collector, belonging to the field of inspection apparatus and comprising a vein puncture needle 1, a connecting tube 2, and a negative pressure tube puncture needle 3. The vein blood collector is characterized in that: an adhesive band 5 is arranged on the middle position of a needle handle 4 of the vein puncture needle 1 and used for fixing the vein puncture needle 1, and a flow controller 6 is arranged on the connecting tube 2 so as to effectively prevent the blood from flowing too fast and lead blood cells to collide mutually and be damaged; and when the negative pressure is connected, the blood flow can be stopped so as to prevent the blood from flowing out. The vein blood collector has simple structure and convenient use, can effectively prevent the needle from displacement, penetration or quit a blood vessel during blood collection, can control the blood flow rate in time and prevent the blood cells from being damaged, and ensures the smooth operation of the blood collection process.
Description
Technical field: this utility model belongs to the check instrument field, be particularly related to a kind of syringe needle that can effectively prevent and when blood sampling, be shifted, wear out or withdraw from blood vessel, and can in time control velocity of blood flow, prevent hematoclasis, the assurance blood collection procedure is carried out smoothly, vein hemostix simple in structure, easy to use.
Background technology: the venous blood collection chemical examination is a requisite project in the daily curative activity.At present, the staff of clinical laboratory earlier with syringe suction blood in the blood vessel, again with the blood injecting tube, delivers to the laboratory then and chemically examines when collecting blood sample.This blood sampling mode, program is more loaded down with trivial details, and the chance that the blood sample of collection is polluted also will increase greatly.After serve medical institutions and improved hemostix, this hemostix is made up of venipuncture needle, connection tube and negative pressure pipe puncture needle, the staff is when blood sampling, need pull adhesive plaster in addition syringe needle is fixed, otherwise syringe needle will be shifted, wears out or withdraw from blood vessel, and in blood collection procedure or during changing-over negative pressure pipe, velocity of blood flow is wayward, the destruction that causes hemocyte, the accuracy of influence chemical examination brings unnecessary loss and misery to patient.
Summary of the invention: the purpose of this utility model is to provide a kind of can effectively prevent syringe needle displacement when blood sampling, wear out or withdraw from blood vessel, and can in time control velocity of blood flow, and preventing hematoclasis, the assurance blood collection procedure is carried out smoothly, vein hemostix simple in structure, easy to use.
For achieving the above object, this utility model has been taked following technical scheme: this vein hemostix, constitute by venipuncture needle, connection tube, negative pressure pipe puncture needle, the centre position of the needle handle of venipuncture needle is provided with adhesive band, and in order to fixing venipuncture needle, connection tube is provided with flow controller, can prevent effectively that flow velocity is too fast and make the hemocyte destruction that is impacted, when changing-over negative pressure pipe, can in time press from both sides and close blood flow, in order to avoid blood flows out.
This utility model, simple in structure, easy to use, can effectively prevent syringe needle displacement when blood sampling, wear out or withdraw from blood vessel, and can in time control velocity of blood flow, prevented hematoclasis, guaranteed carrying out smoothly of blood collection procedure.
Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
With reference to accompanying drawing 1,1, venipuncture needle, 2, connection tube, 3, negative pressure pipe puncture needle, 4, the venipuncture needle needle handle, 5, adhesive band, 6, flow controller.
The specific embodiment: this utility model, except that piercing needle, all be made with the non-toxic sanitary elastomeric material, constitute by venipuncture needle 1, connection tube 2, negative pressure pipe puncture needle 3, the centre position of the needle handle 4 of venipuncture needle 1 is provided with adhesive band 5, and connection tube 2 is provided with flow controller 6.
When using this utility model, earlier venipuncture is needled into vein blood vessel, see blood back is arranged after, be attached to the adhesive band on the needle handle on the patient skin fixing, then negative-pressure puncture needle is inserted in the ready negative pressure pipe, blood just flows out along connection tube under the suction function in endovascular blood pressure and negative pressure pipe, to required blood volume, folder closes flow controller, do another blood test as need, then negative-pressure puncture needle is inserted and continue blood sampling in another negative pressure pipe,, then extract the venipuncture syringe needle and get final product as not continuing blood sampling.
