The arm fixing part 1 can be fixed on a metal base or a fixing platform through the arm magnet 1.8, so that the arm fixing part 1 is prevented from being driven by a patient, and the safety of blood sampling is further ensured.

As shown in fig. 3, in the present invention, the finger fixing portion 2 includes a finger bottom plate 2.1 and a finger top plate 2.2 that are matched with each other. Wherein, a plurality of arc-shaped clamping grooves which are symmetrical to each other are arranged on the opposite surfaces of the finger bottom plate 2.1 and the finger top plate 2.2 so as to form a finger clamping groove 2.3. When blood is collected, the finger of a blood-collecting patient is placed in the finger clip groove 2.3. The utility model discloses in, finger clip groove 2.3 is oval to make its appearance more similar with blood sampling patient's finger.

Preferably, four arc-shaped clamping grooves which are symmetrical to each other are arranged on the opposite surfaces of the finger bottom plate 2.1 and the finger top plate 2.2 so as to form four finger clamping grooves 2.3. Therefore, the four fingers except the thumb of the blood sampling patient can be fixed at the same time, and the interference and influence of other fingers on the blood sampling finger during blood sampling are prevented. More preferably, each finger grip groove 2.3 is provided with finger pads 2.4 on its inner wall. Therefore, on one hand, the fingers of the blood sampling patient can be prevented from being pinched, and on the other hand, the blood sampling patient can feel more comfortable.

Two bilateral symmetry pillars 2.5 are arranged on the finger bottom plate 2.1. One end of each strut 2.5 is fixedly connected with the top surface of the finger pad 2.1. Through holes are arranged in the finger top plate 2.2. The other end of the strut 2.5 penetrates through the through hole in the finger top plate 2.2, and the other end is provided with a limiting lug 2.7. The finger compression spring 2.6 is sleeved on the supporting column 2.5 between the limiting bump 2.7 and the top surface of the finger top plate 2.2. Thus, the bottom surface of the finger top plate 2.2 is pressed against the top surface of the finger bottom plate 2.1 by the finger compression spring 2.6.

Preferably, a finger magnet 2.8 is fixed on the bottom surface of the finger bottom plate 2.1. The finger fixing part 2 can be fixed on the metal base or the fixing platform through the finger magnet 2.8, so that the finger fixing part 2 is prevented from being driven by a patient, and the safety of blood sampling is further ensured.

Use the utility model discloses a when fixing device for blood sampling is sampled blood to the patient, at first pass through arm magnet 1.8 will arm bottom plate 1.1 is fixed, then manual upwards lifts up arm roof 1.2 is in order to overcome arm compression spring 1.6's elasticity, thereby makes arm clamp groove 1.3's space grow makes blood sampling patient's forearm pass arm clamp groove 1.3 later puts down arm roof 1.2 under arm compression spring 1.6's the effect, is in blood sampling patient's arm centre gripping in the arm clamp groove 2.3. Then, the screw rod 3 is rotated to adjust the distance between the finger fixing part 2 and the arm fixing part 1, after the distance is adjusted, the finger bottom plate 2.1 is fixed through the finger magnet 2.8, then the finger top plate 2.2 is manually lifted upwards to overcome the elastic force of the finger compression spring 2.6, so that the space of the finger clamping groove 2.3 is enlarged, the finger of the blood sampling patient passes through the finger clamping groove 2.3, then the finger top plate 2.2 is put down, and the finger of the blood sampling patient is clamped in the finger clamping groove 2.3 under the action of the finger compression spring 2.6.

The utility model discloses a fixing device for blood sampling easy operation only needs to upwards lift up arm roof and finger roof and overcomes corresponding compression spring's elasticity and can realize the fixed of arm and finger, and efficiency is than higher, the medical personnel's of being convenient for use.
