Embodiment Construction
[0034] The present invention will be described in further detail below by means of specific embodiments:
[0035] The reference signs in the drawings of the description include: tee pipe 10, puncture hose 11, pipe sleeve 111, isolation plug 12, vent hole 13, raised strip 14, vertical groove 15, steel needle holder 21, groove 211, steel Needle holder 22, handle 221, embossed pattern 222, steel needle 23, blood collection needle holder 31, blood collection needle 32, blood collection needle cover 321, sheath 322, collection tube 33, silica gel plug 40, protrusion 41, vacuum blood collection tube 50, Blood 60.
[0036] Such as figure 1 As shown, the multiple blood collection indwelling needle includes a three-way tube 10 , a steel needle assembly, a blood collection assembly and a silicone plug 40 . The tee pipe 10 is made of, and the angle between the rear end of the main pipe and the side pipe is an acute angle. The front end of the main pipe of the three-way pipe 10 is conn...

The invention belongs to the technical field of medical instruments and particularly discloses a repeatedly blood-sampling indwelling needle. The repeatedly blood-sampling indwelling needle comprises a three-way tube, a steel needle component, a blood-sampling component and a silicone rubber plug, wherein the silicone rubber plug is positioned inside the three-way tube and capable of sliding inside the three-way tube; the steel needle component comprises a steel needle seat, a steel needle and a steel needle holder, the steel needle is fixed on the steel needle seat, and the steel needle holder penetrates through the steel needle; the front end of a main tube body of the three-way tube is communicated with a piercing hose, and the back end of the main tube body of the three-way tube is detachably connected with the steel needle holder; the blood-sampling component comprises a blood-sampling needle seat, a blood-sampling needle is arranged at one end of the blood-sampling needle seat, a collecting tube is arranged at the other end of the blood-sampling needle seat, and a blood-sampling needle sleeve sleeves the blood-sampling needle; a side tube body of the three-way tube is communicated with the collecting tube, the back end of the main tube body is positioned at the silicone rubber plug position, and a vent hole is formed in the back end of the main tube body. The invention discloses an application method of the repeatedly blood-sampling indwelling needle. Compared with the prior art, the repeatedly blood-sampling indwelling needle has the advantages that pain of patients is alleviated greatly only through vascular puncturing once as for the patients requiring repeated blood sampling, so that blood-sampling efficiency and safety are improved comprehensively.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to an indwelling needle for multiple blood collections. Background technique [0002] Under modern medical conditions, before diagnosing a patient, a doctor must first collect blood from the patient and conduct a laboratory test on the blood, and make a scientific judgment based on the test results combined with the patient's symptoms to ensure the accuracy of the diagnosis. Therefore, blood collection is an indispensable link for patients to see a doctor. Usually the hospital blood collection, all is to use disposable blood collection to carry out venipuncture for patient's blood vessel, just will disposable blood collection needle be pulled out discarded after blood collection. [0003] For patients who only need to do general physical examination or simple disease examination, the examination process only needs to take blood once, and use a disposable blood collection ne...
