Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an inflatable bandaging device. Background Art

[0002] Medical devices refer to equipment, instruments, supplies, materials and other types of products used for the prevention, diagnosis, treatment, and relief of human diseases, injuries or disabilities, as well as medical cosmetology. In the treatment process of trauma orthopedics, it is necessary to bandage the injured areas of some trauma patients. At this stage, the use of airbag inflation can quickly squeeze and bandage the injured areas of patients.

[0003] After searching, the authorization announcement number CN214712971U and the authorization announcement date 2021.11.16 disclose an inflatable trauma orthopedic bandaging device, which belongs to the field of medical device technology. The inflatable trauma orthopedic bandaging device includes a shell, a slanted rod is fixedly connected to the surface of the shell, and an inflator is detachably connected to one end of the slanted rod. A through hole is opened on the surface of the shell, and a first textile layer is inlaid and connected to the inner side of the through hole. A groove is opened on the surface of the first textile layer, and an airbag is cooperatively connected inside the groove. A catheter is inlaid and connected to one end of the inflator, and one end of the catheter is detachably connected to the surface of the airbag. When the inflator is working, gas is generated inside to exhaust the catheter inlaid at one end thereof, and the catheter transmits the gas to the airbag detachably connected at one end. The airbag is inlaid and connected in the groove opened on the inner side of the first textile layer, so that the airbag is inflated to quickly squeeze and bandage the patient, so that it has a higher bandaging effect on human body parts and improves the fixation measures for the human body as a whole.

[0004] However, the existing technology has the following shortcomings:

[0005] 1. When the above-mentioned trauma orthopedic inflatable bandage device is used, the patient's joint is placed inside the through hole opened inside the shell, and the inflator is started to allow gas to enter the inside of the airbag, so that the airbag is expanded to achieve rapid compression bandage of the patient. However, in actual use, since the diameter of the ring is fixed, and the thickness of the limbs of the human body varies, the ring cannot be adapted to the limbs of varying thicknesses during use;

[0006] 2. When the above-mentioned trauma orthopedic inflatable bandaging device is in use, the distance between the ring and the shell can be adjusted by the electric telescopic rod. However, in actual use, there is still a certain distance between the ring and the shell when the electric telescopic rod is retracted to the upper limit, resulting in a large space being occupied when stored.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figures 1 to 3As shown, the utility model is an inflatable bandaging device, comprising a ring 2, wherein the inside of the ring 2 is symmetrically provided with a splint 4, and the adaptability to limb parts of different thicknesses is achieved by adjusting the distance between the two splints 4, and a screw rod 1 is arranged on the outside of the splint 4, and the screw rod 1 penetrates the ring 2 and is threadedly connected with the ring 2, and the corresponding splint 4 can be moved by rotating the screw rod 1, so as to adjust the distance between the two splints 4, and the screw rod 1 is rotatably connected with the splint 4 through a bearing;

[0031] With the above arrangement, when bandaging a patient, the housing 3 is operated so that the patient's joint is located inside the airbag 3011, and the screw 1 is rotated to drive the corresponding splint 4 to move until the splint 4 forms a clamping state for the patient's limb. At this time, the air pump 303 is operated to generate airflow, and the airflow passes through the connecting tube 3031 and enters the interior of the airbag 3011 to expand the airbag 3011 to quickly squeeze and bandage the patient. After the bandaging is completed, the airbag 3011 is deflated, and the housing 3 is removed from the patient's limb.

[0032] The splint 4 is arranged in an arc shape. Since the limbs of the human body are round, the splint 4 is arranged in an arc shape to adapt to the limbs of the human body. The inner side wall of the splint 4 is fixed with a second sponge sheet 401. When the limbs of the human body are clamped, the second sponge sheet 401 is in contact with the limbs of the human body, which can increase the comfort during use.

[0033] A screw block 101 is fixed to one end of the screw rod 1 away from the clamping plate 4, and the screw block 101 is circular. The screw rod 1 can be rotated by operating the screw block 101. The outer peripheral wall of the screw block 101 is provided with anti-slip grooves 1011, which can increase the friction between the hand and the screw block 101 when the screw block 101 is rotated.

[0034] The outer peripheral walls on both sides of the circular ring 2 are fixed with rotating rods 201, and the circular ring 2 can be rotated at this position through the rotating rods 201, so that the circular ring 2 can be conveniently adjusted in angle and placed for different joints. The outer side walls of the splint 4 corresponding to the left and right sides of the screw rod 1 are fixed with limiting rods 402, and the limiting rods 402 pass through the circular ring 2 and cooperate with the clearance of the circular ring 2. The setting of the limiting rods 402 can prevent the splint 4 from rotating when the screw rod 1 rotates.

[0036] With the above arrangement, after use, the screw rod 2 6 and the corresponding mobile tube 5 are out of contact state, and the mobile tube 5 and the fixed tube 302 can move relative to each other. At this time, the mobile tube 5 is controlled to retract into the interior of the fixed tube 302, and the ring 2 is brought into contact with the shell 3, and then the screw rod 2 6 and the corresponding mobile tube 5 are operated to be in contact state, so that the inflatable bandaging device can be stored;

[0037] A sponge sheet 301 is fixed to the outer peripheral wall of the airbag 3011, and the sponge sheet 301 is fixedly connected to the shell 3, so that the sponge sheet 301 increases the degree of protection for the user and improves the user experience; a connecting pipe 3031 is fixed to the air inlet of the airbag 3011, and the other end of the connecting pipe 3031 is fixedly connected to the air outlet end of the air pump 303. With the above arrangement, the connecting pipe 3031 can be a hose. When the air pump 303 is working, the gas generated by the air pump 303 passes through the connecting pipe 3031 and enters the interior of the airbag 3011;

[0038] The movable tube 5 and the fixed tube 302 are clearance-matched to prevent the movable tube 5 from shaking, and the screw rod 2 6 is in contact with the movable tube 5.
