[0027] Reference Figs. 1-3 The utility model provides a kind of puncture side lower limb fixing device after intervention, including fixing piece 10 and the fixing belt 20 being set to fixing piece 10.
[0028] The T-shaped air bag of fixing piece 10 is made of medical-grade high-strength rubber or high-quality polyurethane material, with good flexibility, air tightness and pressure resistance. The wide part of the upper part (waist fixing part) is 20-30 cm wide, and the length can be designed as 60-80 cm according to the waist circumference range of common adult, and the shape is flat and long strip-shaped to better wrap around the waist. The long part of the lower part (leg fixing part) is 10-15 cm wide, and the length is 40-60 cm, and its shape fits the leg side curve, extending from the upper part of the thigh to the slightly upper position of the calf, and the edges of fixing piece 10 are all provided with a curvature to prevent scratching.
[0029] In specific implementation, the fixing belt 20 is selected as a nylon webbing with a width of 3-5 cm, which has a certain elasticity and high strength. One end of the webbing is firmly connected to one side edge of the T-shaped air bag by sewing, and 3-5 strips of the webbing are evenly distributed along the length direction of the air bag. The fixing member 10 is fixed to the waist and legs of the patient, and the leg fixing part 12 is provided with the fixing belt 20 between the knee and the ankle. The other end of the fixing belt 20 is sewn with a hook surface and a loop surface of a Velcro, and the length of the hook surface and the loop surface is about one third of the length of the webbing. The Velcro has good adhesion and durability, and can be repeatedly used. The overall length of the fastening belt 21 is designed according to the actual use requirement, so as to ensure that the fastening belt 21 can pass around the root of the thigh of the patient and be effectively fixed. The end of the fastening belt 21 fixed to the leg fixing part 12 is an elastic belt, and the Velcro of the other end has the same material as the fixing belt 20. The length of the elastic belt part is adjusted according to the distance between the leg fixing part 12 and the root of the thigh and the elastic tension required to be applied, and is generally 10-20 cm, so as to provide a moderate elastic extension range and adapt to the requirements of different patients in different leg thicknesses and activity states. The length of the Velcro part is similar to that of the Velcro on the fixing belt 20, and is about one third of the total length of the fastening belt, so as to ensure a sufficient adhesion area to achieve stable fixation.
[0030] In specific implementation, the valve 111 is installed on the waist fixing part 11, and is two air charging valves 112. The air charging valves are medical micro one-way air charging valves. The air charging valves have a structure similar to the air charging valve of a tire or a rubber boat, are usually made of plastic, and have an elastic rubber valve core in the internal structure. When an external air source (such as a manual air pump or an electric air pump) is connected to the air charging valve, the gas pressure overcomes the resistance of the valve core to enter the T-shaped air bag. When there is no external air source pressure, the valve core is automatically closed to prevent the backflow of the gas in the air bag. The air charging valve is installed on the waist fixing part 11 in a threaded connection manner, and is provided with a rubber sealing washer to ensure the tightness and air tightness of the connection. The other is a deflation valve 113, which has a sealing plug in the internal structure. In the normal state, the sealing plug blocks the deflation passage. When deflation is required, the sealing plug is pulled out. The deflation valve 113 is also connected to the T-shaped air bag in a threaded connection manner, and is kept at a distance from the air charging valve for convenient operation. The connection part is also provided with a rubber sealing member to prevent gas leakage.
[0031] Working principle: Before use, the leg fixing part 12 of the uncharged T-shaped air bag is placed on the side of the lower limb of the patient on the puncture side, so that the bottom is located at a suitable position below the knee and above the ankle, and then the waist fixing part 11 is wound around the waist of the patient.
[0032] The inflation valve 112 is connected to an external air source for inflation. According to the patient's comfort and fixation requirements, the T-shaped air bag is inflated with appropriate amount of air. During the inflation process, the inflation of the air bag and the fit with the patient's body are observed. When the air bag is gradually inflated and closely fitted to the patient's body, the inflation is stopped.
[0033] Next, the fixing belt 20 is wrapped around the patient's body or limbs. The position of the Velcro is adjusted according to the patient's body size, and the fixing belt is adjusted to the appropriate tightness, so that the T-shaped air bag is stably fixed on the patient's body. In particular, the fastening belt 21 at the thigh root compression hemostasis position is tightened and fixed, further ensuring the stable fixation of the puncture site. During the 24-hour period of the patient's bed rest, the device can continuously and effectively maintain the straight state of the lower limb on the operative side, limit the large bending of the knee joint and hip joint, and at the same time, do not affect the normal activity of the ankle joint.
[0034] When the 24-hour fixation period is over or in special circumstances, the deflation valve 113 is operated to slowly discharge the air in the air bag. During the deflation process, the contraction of the air bag is observed. When the air bag is completely deflated, the device can be easily removed from the patient's body.
[0035] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
