Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to disposable blood sample extraction element.
Background technology:
Patient, when examination in hospital, often carries out blood examination, and doctor can learn the state of an illness of patient according to the blood examination report of patient, the method extracting now blood sample is substantially all adopt puncture needle blood drawing, and the blood injecting tube then will extracted, waits to be detected.When taking a blood sample, infant, old man, when the patients such as skin edema take a blood sample, because syringe needle tube, puncture needle is in the state of being rigidly connected, be difficult to children's cry and scream struggle and adjust orientation flexibly, cause inserting needle difficulty large, not easily puncture successfully, during the puncture of nursing staff's hand syringes, as long as position changes a little, the needle point of puncture needle is easy to or injured blood vessel, greatly reduce the success rate of blood sampling, unnecessary misery is brought to patient, simultaneously, also to move in test tube again after this method blood sampling, formality is loaded down with trivial details, operation inconvenience, when moving into test tube, easy destruction blood sample cell and cause blood sample to pollute, add the chance of cross infection.In order to solve the above problems, need to improve existing technology.
Utility model content:
The purpose of this utility model is to provide disposable blood extraction element, and its structure is simple, reasonable in design, than existing puncture needle more convenient operation, reduces the pain that patient bears, blood sample cell can be protected from destruction, and avoid blood sample to be polluted.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: it comprises blood sample test tube 1, graduation mark layer 2, flexible pipe 3, acupuncture handle 4, syringe needle 5, sealing ring 6, seal cover 7, unidirectional air outlet valve 8, escape pipe 9, the surface of blood sample test tube 1 is provided with graduation mark layer 2, the top of blood sample test tube 1 is provided with sealing ring 6, sealing ring 6 is provided with seal cover 7, flexible pipe 3 is provided with in the middle of the top of blood sample test tube 1, the side of flexible pipe 3 is provided with escape pipe 9, the lower end of flexible pipe 3 is all connected with blood sample test tube 1 through seal cover 7 with the lower end of escape pipe 9, unidirectional air outlet valve 8 is provided with above escape pipe 9, one end of flexible pipe 3 is provided with acupuncture handle 4, one end of acupuncture handle 4 is provided with syringe needle 5.
Described blood sample test tube 1 is transparent plastic flexible pipe.
Operation principle of the present utility model is: medical personnel are when carrying out blood sample and extracting to patient, syringe needle 5 is thrust patient vessel by hand-held acupuncture handle 4, gently pinch blood sample test tube 1, air in blood sample test tube 1 can be discharged by escape pipe 9, under pressure action, the blood of patient can enter blood sample test tube 1 from flexible pipe 3, and medical personnel grasp the T/A extracting blood according to graduation mark layer 2.
This utility model has following beneficial effect: its structure is simple, reasonable in design, than existing puncture needle more convenient operation, reduces the pain that patient bears, blood sample cell can be protected from destruction, and avoid blood sample to be polluted.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
