Abstract
The utility model discloses a blood sampler, and belongs to the technical field of medical appliances. The blood sampler comprises a needle cylinder and a needle head, one end of a blood drawing tube, one end of a blood sampling tube and one end of a blood inlet tube are fixedly connected and communicated with one another through a three-way switch, the other end of the blood inlet tube is fixedly connected and communicated with the needle cylinder, and a hose of 5-8 mm in length is arranged between the needle head and the blood drawing tube. When the blood sampler is used, the needle head is inserted in the blood drawing tube and penetrates the blood vessel, the three-way switch rotates to the blood drawing tube to be communicated with the blood inlet tube, the pintle is drawn to lead blood to enter into the needle cylinder, after the needle cylinder is filled with blood, the three-way switch rotates, then the blood inlet tube is communicated with the blood sampling tube, blood in the needle cylinder is pushed into the sampling test tube through the blood sampling tube, and the operation of drawing a larger amount of blood can be finished through one-time puncture with the needle head, so that the phenomena of repeated puncture of the needle head and cross infection are avoided. The needle head is connected with the syringe via the hose, the hose can be arbitrarily bent during the blood sampling process, so as to be convenient for blood sampling, the success ratio is greatly improved, and blood is drawn into the syringe before coagulation, further the requirements of testing are met.
Description
Technical field
This utility model relates to the medical device technical field, relates in particular to a kind of blood sampling device.
Background technology
When drawing blood chemical examination to patient, blood draw is generally used syringe, its syringe needle and syringe directly connect as one, complicated for patient's state of an illness, the blood flow volume that often extracts an injection needle on arm when drawing blood can not satisfy the chemical examination requirement, will be interrupted in the case and extract twice or three times, operation is trouble.Special when the blood drawing position as cervical region or when being used for pediatric patient, because the position is special, the space is narrow and small and the influence of syringe volume length, brings very burden to taking a blood sample, success rate is low, has also brought misery to patient.The method that adds one section flexible pipe between syringe and syringe needle is also arranged at present, but since institute to add hose length inappropriate, normally long partially, cause blood sample in elongated flexible pipe, to catch a cold and condense, the influence chemical examination.Also have in syringe, to add anticoagulant, in case the agglomerative method of hemostasis liquid, but use trouble, also increased expense.There is the people that existing technology is improved for this reason, disclosed by utility model patent Li Jun, Chen Guilin design, that the patent No. is 200820226794.3, name is called a kind of blood sampling device as State Intellectual Property Office on October 21st, 2009, bloodletting tube, blood specimen tube and the end that advances blood vessel be mutually permanently connected by three-way cock communicate, the other end and the syringe that advance blood vessel are fixedly connected, and pintle inserts in the syringe.This blood sampling device knot is simple, convenient, time saving and energy saving, just can finish the collection of larger amt blood with the syringe needle one-time puncture, has avoided syringe needle repeatedly to puncture and cross infection.Its shortcoming is: syringe needle and syringe directly connect as one, special when the blood drawing position as cervical region or when being used for pediatric patient, because the position is special, the space is narrow and small and the influence of syringe volume length, brings very burden to taking a blood sample, success rate is low, has also brought misery to patient.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, safe in utilization blood sampling device.
The technical scheme that this utility model is adopted for achieving the above object is:
A kind of blood sampling device, comprise syringe and syringe needle, bloodletting tube, blood specimen tube and an end that advances blood vessel are mutually permanently connected by three-way cock and communicate, and the other end and the syringe that advance blood vessel are fixedly connected, and it is characterized in that: be provided with flexible pipe between described syringe needle and the bloodletting tube.
Described hose length is 5-8 centimetre.
A kind of blood sampling device of the present utility model, bloodletting tube, blood specimen tube and an end that advances blood vessel are mutually permanently connected by three-way cock and communicate, the other end and the syringe that advance blood vessel are fixedly connected, and are provided with flexible pipe between syringe needle and the bloodletting tube, and hose length is less than 8 centimetres.During use, syringe needle is inserted on the bloodletting tube and the intravasation that punctures, three-way cock is rotated to bloodletting tube and advance blood vessel and communicate, pull pintle blood enters in the syringe, when blood in syringe, take out full after the swivel tee switch make into that blood vessel and blood specimen tube communicate, annotate the bolt of pushing pin the blood in the syringe pushed in the sampling test tube through the blood probe tube; Use it simple to operation time saving and energy saving, just can finish extraction larger amt blood with the syringe needle one-time puncture and avoid syringe needle repeatedly to puncture and cross infection.Because syringe needle and syringe are by hose connection, in the flexible pipe bending of can transferring arbitrarily of when blood sampling, not influenced by syringe, being convenient to blood sampling and success rate greatly improves, also alleviated patient's misery, simultaneously since the length of flexible pipe only below 8cm, blood does not condense as yet and promptly has been extracted in the syringe, meets the requirement of chemical examination.
Description of drawings
Accompanying drawing is the sketch map of a kind of blood sampling device of this utility model.
Among the figure: the 1-syringe, the 2-syringe needle, the 3-bloodletting tube, the 4-blood specimen tube, 5-advances blood vessel, 6-three-way cock, 7-flexible pipe.
The specific embodiment
Accompanying drawing is the sketch map of a kind of specific embodiment of this utility model blood sampling device, this blood sampling device comprises syringe 1 and syringe needle 2, bloodletting tube 3, blood specimen tube 4 and an end that advances blood vessel 5 are mutually permanently connected by three-way cock 6 and communicate, the other end and the syringe 1 that advance blood vessel 5 are fixedly connected, be provided with flexible pipe 7 between syringe needle 2 and the bloodletting tube 3, flexible pipe 7 length are 8 centimetres.
