[0035] like Figure 1-6As shown, a hemostatic compressor comprises a compressor body 1, on which a compression airbag 2 and an inflation mechanism are arranged, and the inflation mechanism is composed of an air cylinder 3, an air supply pipe 4, a piston 5, a push rod 6, a push handle 7, a pull block 8, a pull rod 9, a spring 10 and a limit block 11, and the push rod 6 and the limit block 11 are both provided with mutually matching limit teeth 12, one end of the air supply pipe 4 is connected to the air cylinder 3, and the other end thereof passes through the compressor body 1 and is connected to the compression airbag 2, the compression airbag 2 is bonded to the adhesive 14 arranged on the hemostatic pad 13, and a card slot 15 and a card hole 16 are provided on the compressor body 1, and the card slot 15 is card-engaged with a card seat 18 arranged on the reel 17, and the card hole 16 is card-engaged with the card seat 18. The spring block 19 is provided for a snap-fit connection, and a reel 20, a pressing block 22 and a spring 23 are provided inside the reel 17. The reel 20 is rotatably connected to the reel 17, and a coil spring is provided at the rotatable connection. A bandage 21 is rolled up on the reel 20. The utility model can not only adapt to the patient's circumference and quickly change the binding pressure, but also compress and stop bleeding on the patient's wound. At the same time, the establishment of the hemostatic pad 13 can further increase the effectiveness of hemostasis. The compression airbag 2 is provided at the bottom end of the compressor body 1, and the inflation mechanism is provided at the top end of the compressor body 1, and the piston 5 is located inside the air cylinder 3 and is connected to one end of the push rod 6, and the other end of the push rod 6 passes through the air cylinder 3 and is connected to the push handle 7 located outside. When the patient is at the wound, it is only necessary to push the push handle 7 to drive the piston 5 to move toward the connecting end of the air supply pipe 4 through the push rod 6, that is, the gas can be filled into the compression airbag 2 through the air supply pipe 4 to increase the compression force after it expands. The pull rod 9 is located inside the air cylinder 3, one end of which passes through the air cylinder 3 and is connected to the pull block 8 located outside, and the other end is connected to the limit block 11, and a spring 10 is sleeved on the outer end of the pull rod 9, and the limit tooth 12 on the limit block 11 is set at the other end away from the pull rod 9 and inclined toward the push handle 7, and the limit tooth 12 on the push rod 6 is set at one end near the limit block 11 and inclined toward the piston 5. The limit tooth 12 on the limit block 11 is relative to the limit tooth 12 on the push rod 6. When the push rod 6 moves inward, the limit block 1 The limiting teeth 12 on 1 and the limiting teeth 12 on the push rod 6 can be continuously staggered to make the push rod 6 move smoothly. When the push rod 6 moves outward, the limiting teeth 12 on the limiting block 11 are engaged with the limiting teeth 12 on the push rod 6, which can limit the outward movement of the push rod 6 to prevent it from moving outward by itself and affecting the compression force of the compression airbag 2. When the pull block 8 is pulled through the pull rod 9 to drive the limiting block 11 to move outward to compress the spring 10, so that the upper limit tooth 12 is separated from the upper limit tooth 12 of the push rod 6, the limiting state of the push rod 6 can be released, so as to suck the gas in the compression airbag 2 and adjust its expansion degree.

The cylinder 3 is transparent, and a scale line 27 is set on the cylinder 3. Through the establishment of the scale line 27 on the cylinder 3, it is convenient to determine the amount of gas in the compression airbag 2 according to the moving distance of the piston 5. ,
[0036] The working principle of the utility model is as follows: after removing the film covering layer adhered to the hemostatic pad 13, the adhesive 14 can be placed at the bottom of the compression airbag 2 to fix the position of the hemostatic pad 13, so that when the hemostatic pad 13 covers the wound of the patient, the holder 18 is clamped in the clamping groove 15, and the spring clamping block 19 on the holder 18 is clamped in the clamping hole 16, so that the installation and fixing operation of the reel 17 on the compressor body 1 is completed, so that the reel 20 rewinds the strap 21 under the action of the coil spring, so that the strap 21 adapts to the patient. The limb circumference is measured, and then the pressing block 22 is pressed inwardly, so that the spring clamping block 24 arranged on it pops outward and is clamped in the clamping hole 25 opened on the reel 17, completing the fixing operation of the pressing block 22. The tooth portion set at the bottom end of the pressing block 22 presses the strap 21 inside the belt outlet end of the reel 17, that is, it can limit the movement of the strap 21 in and out. When the push handle 7 is pushed, the piston 5 is driven to move toward the connecting end of the air supply pipe 4 through the push rod 6, that is, gas can be filled into the compression airbag 2 through the air supply pipe 4, so that after it is expanded, the compression force is increased.
