Among them, the detailed structure of each gas nozzle 22 has been described in detail above, and will not be repeated here. In addition, each of the first joining portions 321 is located on the outer surface of the belt 30, each of the second joining portions 322 is located on the inner surface of the belt 30, and each of the second joining portions 322 includes two arm portions 325. The parts 325 are arranged in a direction perpendicular to the extending direction of the belt 30 and respectively extend along the extending direction of the belt 30. A gap 326 is formed between the two arm parts 325, and the inner surfaces of the two arm parts 325 are respectively laid In the devil felt, when each of the first joining parts 321 and the corresponding second joining parts 322 are connected and fixed to each other, the air nozzle 324 is located in the gap 326 between the two arm parts 325.

In actual use, as shown in Figures 1 to 11, the belt body 10 without the first part and the second part can be used to wrap the calf, and the belt body 30 with the first part 31 and the second part 32 can be used to wrap The pelvic part and the thigh part, the first part 31 corresponds to the pelvis part, the second part 32 corresponds to the thigh part respectively, and is wrapped and positioned respectively, and then the inflatable tube 40 is connected to the air nozzles 22, and the inflatable device Connect these inflatable tubes 40 to achieve the purpose of counterpulsation therapy by repetitive rapid inflation and inhalation of the inflation device, and promote blood circulation and vascular hyperplasia; in addition, the counterpulsation inflator provided by this creation can also be used for non-counterpulsation therapy The purpose is to fasten the blood circulation in the body by attaching the belt to the limbs of the body during the compression process to achieve body massage and muscle relaxation.

It should be noted that the air nozzle 22 of the belt body 10 is shown in FIG. 10, and is set on the inner side of the human leg for illustrative purposes only. In fact, the best position of the air nozzle 22 of the belt body is As shown in FIG. 11, when the strap is fixed on the thigh or calf, it is located outside the thigh or calf, so that the inflatable tube 40 and the air nozzle 22 will not interfere with the legs when they are connected to each other.

In particular, the air nozzle may not be located in the gap between the two arm portions. For example, as shown in FIG. 11, the air nozzle may be located at an end close to the second joint portion, so that the inflatable tube 40 can be free from the body. Connect air nozzles on both sides.

In particular, because the TPU layers 2111, 2121 of the first sheet 211 and the second sheet 212 of the bag body 21 all face the same direction, the expansion direction of the bag body 21 is mainly outward, avoiding a single The compression of the position can achieve the uniform effect of the belt body 10, 30 shrinking together.

In summary, the counterpulsation inflator provided by this creation has a detachable belt body and an airbag bag. The belt body can be cleaned. If the airbag bag is damaged or damaged, it can be replaced, or it can be replaced with a different size and different inflation volume. The airbag bag to meet different needs, and the expansion effect when inflated is uniform, the service life is long, and it is very effective.
