AI Technical Summary
The existing blood collection needles are one-piece structures, which cannot be used directly with infusion needles or indwelling needles for blood collection, increasing the operation steps and causing needle waste.
A detachable blood collection needle was designed, including a fixed base, a connecting base, and a second needle tip. The fixed base and the connecting head are detachably connected by an internal thread, allowing the needle tip to be adjusted according to the patient's condition.
This avoids repeated needle pricks for patients receiving intravenous infusions, reduces needle usage, improves operational efficiency, and saves resources.

[0005] Preferably, a connector is provided on the fixing seat, a protrusion is provided at the end of the connector, and the connector is threadedly connected to the fixing seat via the protrusion and the internal thread.
[0006] Preferably, the fixing seat and the connecting seat are an integrally formed structure.
[0007] Preferably, a hose is provided on the connector, a needle seat is provided at one end of the hose away from the connector, a first needle is provided on the needle seat, and a first needle protective cover is provided on the first needle.
[0008] Preferably, an outer surface of the connecting seat is provided with an external thread, and a needle holder is provided on the connecting seat, and the connecting seat and the needle holder are fixed by a threaded connection.
[0009] Preferably, a second needle protection cover is provided on the second needle.
[0010] Beneficial effects: Compared with the prior art, the utility model has an internal thread arranged inside the fixing seat, and the fixing seat and the connecting head are detachably connected. During the blood collection process, blood can be drawn according to the conditions of different patients, which can avoid re-insertion of patients who are receiving infusion. On the other hand, it can reduce the use of needles and save environment. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation
[0015] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods. Example
[0016] Please refer to the drawings in the specification. In the embodiment of the utility model, a detachable blood collection needle is provided, which includes a fixing seat 1, a connecting seat 2 and a second needle head 3. The fixing seat 1 is a cylindrical structure with an opening on one side. An inner sleeve 4 is arranged inside the fixing seat 1. The connecting seat 2 is arranged at the closed end of the fixing seat 1. The fixing seat 1 and the connecting seat 2 are an integrally formed structure. Through holes are arranged at the middle positions of the fixing seat 1 and the connecting seat 2, and the fixing seat 1 and the connecting seat 2 are connected through the through holes; the second needle head 3 is arranged on the end of the connecting seat 2 away from the fixing seat 1; an internal thread 5 is arranged on the inner wall of the fixing seat 1, and an inner thread 5 is arranged on the fixing seat 1. There is a connector 6, a protrusion 7 is provided at the end of the connector 6, and the connector 6 and the fixing seat 1 are threadedly connected with the internal thread 5 through the protrusion 7, which is convenient for fixing and disassembly between the fixing seat 1 and the connector 6, and a hose 8 is provided on the connector 6, and a needle seat 9 is provided at the end of the hose 8 away from the connector 6, and a first needle 10 is provided on the needle seat 9, and a first needle protection cover 11 is provided on the first needle 10; the outer surface of the connecting seat 2 is provided with an external thread 12, and a needle holder 13 is provided on the connecting seat 2, and the connecting seat 2 and the needle holder 13 are fixed by threaded connection; the second needle 3 is provided with a second needle protection cover 14.
[0017] The utility model is provided with an internal thread 5 inside the fixing seat 1, and the fixing seat 1 and the connecting head 6 are detachably connected. During the blood collection process, blood can be drawn according to the conditions of different patients, which can avoid the patient who is receiving an infusion being pierced with a needle again. On the other hand, the use of needles can be reduced, which is environmentally friendly.
