[0031] like Figure 3 As shown, a connecting ring 101 is fixedly connected to the finger opening of the fingerless glove 1, and an installation ring groove 102 is provided on the connecting ring 101.

[0032] like Figure 4As shown, the inner wall of the fixing seat 2 is fixedly connected with a motor 201, the output end of the motor 201 is fixedly connected with a driving wheel 202, the two sides of the driving wheel 202 are engaged and drivingly connected with two driven wheels 203, one end of the driven wheel 203 is fixedly connected with a rotating shaft 204, the rotating shaft 204 is rotatably connected with the inner wall of the fixing seat 2, and the rotating shaft 204 is fixedly connected with a tension gear 205. The motor 201 drives the driving wheel 202 to rotate, at this time, the driving wheel 202 drives the two engaged driven wheels 203 to rotate in different directions, then the driven wheels 203 drive the connected rotating shaft 204 to rotate, so that the rotating shaft 204 drives the connected tension gear 205 to rotate, so that the tension gear 205 can engage with the rack 301, thereby the two ends of the automatic tension band 3 can be tightened.

[0033] As shown in the figure, Figure 4 The inner wall of the automatic tension band 3 is fixedly connected with a rack 301, and the rack 301 is engaged and drivingly connected with the tension gear 205.

The ring-shaped air bag 704 is fixedly connected on one side with the inner wall of the hemostasis sleeve 701. A piston plate 705 is in sliding fit with the inner wall of the cavity 702. A tension spring 706 is fixedly connected on one end of the piston plate 705. The other end of the tension spring 706 is fixedly connected with the inner wall of the cavity 702. A hemostasis pressing plate 707 is fixedly connected on the other end of the piston plate 705. Hemostasis gauze is placed on the hemostasis pressing plate 707. The tension spring 706 realizes the automatic reset of the piston plate 705. The severed finger will contact the hemostasis gauze and press the hemostasis pressing plate 707, so that the hemostasis pressing plate 707 drives the connected piston plate 705 to move, so that the piston plate 705 can press the air in the cavity 702 through the gas guide tube 703 into the ring-shaped air bag 704, so that the ring-shaped air bag 704 inflates and presses around the severed finger to stop bleeding.

[0038] By setting the finger hemostasis mechanism 7, the hemostasis sleeve 701 can be moved to the broken finger under the drive of the threaded rod 6, and the broken finger will contact and press the hemostasis pressure plate 707.

Rotating the rotary knob 801 connected rotary disc 8, so that the rotary disc 8 drives the connected limiting ring 802 to rotate, and then the limiting ring 802 drives the adjusting wheel 601 to rotate through the annular gear rack 803, so that the adjusting wheel 601 can drive the connected threaded rod 6 to rotate, so that the threaded rod 6 can drive the moving frame 602 to move. The observation port 401 can be observed, so that the moving frame 602 can drive the hemostasis sleeve 701 to move and cover the broken finger.

[0040] Working principle: when the palm broken finger needs to be hemostatic nursing, first put the palm through the automatic elastic band 3 and put the finger glove 1 on the palm, then drive the driving wheel 202 with the motor 201, at this time the driving wheel 202 drives the two meshing driven wheels 203 to rotate in different directions, then the driven wheel 203 drives the connected shaft 204 to rotate, so that the shaft 204 can drive the connected elastic gear 205 to rotate, so that the elastic gear 205 can mesh with the rack 301, so as to tighten the two ends of the automatic elastic band 3. Through the accurate adjustment of the motor 201, the elbow can be accurately tightened, so as to increase the blood flow blockage effect of the broken finger. By adjusting the tightness of the automatic elastic band 3, the venous return of the arm can be effectively controlled, so as to form stronger blood flow blockage at the broken finger, further promote the hemostasis process, the motor 201 can automatically adjust the tightness of the automatic elastic band 3 according to the predetermined time interval, which can avoid the tissue hypoxia or complete interruption of blood circulation caused by excessive compression, and ensure the normal blood supply of other parts of the hand. Through the adjustment of the timing automatic elastic band 3, the specific situation of the patient can be dynamically adjusted according to the change of blood pressure, the condition of the hand and other conditions, so as to maintain appropriate pressure and prevent long-term over tightening from causing tissue damage.

[0041] Then according to the number and position of the severed fingers, the hemostatic sleeve 701 in the finger sleeve 4 is pushed out, the hemostatic gauze is placed in the hemostatic sleeve 701, and then the hemostatic sleeve 701 is retracted, and the finger sleeve 4 is aligned with the severed fingers and inserted on the connecting ring 101, at this time under the action of the spring 506, the mounting block 505 is inserted into the mounting ring groove 102 on the connecting ring 101 for fixation, when the finger sleeve 4 needs to be removed, the pull ring 501 is pushed, so that the pull ring 501 can drive the connecting link 503 to move the hinge B 504, so that the hinge B 504 can drive the mounting block 505 to move out of the mounting ring groove 102, so that the finger sleeve 4 can be removed;

[0042] Then rotate the knob 801 connected to the rotating disc 8, so that the rotating disc 8 drives the connected limiting ring 802 to rotate, and then the limiting ring 802 drives the adjusting wheel 601 to rotate through the ring gear 803, so that the adjusting wheel 601 can drive the connected threaded rod 6 to rotate, so that the threaded rod 6 can drive the moving frame 602 to move, and the observation port 401 can be observed, so that the moving frame 602 can drive the hemostatic sleeve 701 to move around the severed fingers;

[0043] Then the severed fingers will contact the hemostatic gauze and press the hemostatic pressure plate 707, so that the hemostatic pressure plate 707 drives the connected piston plate 705 to move, so that the piston plate 705 can extrude the air in the cavity 702 through the air guide pipe 703 into the annular air bag 704, so that the annular air bag 704 inflates and rises to press around the severed fingers to stop bleeding.
