Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a lower limb disinfection suspension frame. Background Art

[0002] The "bridges" used in heart bypass surgery are divided into arterial bridges and venous bridges, which are taken from different parts of the patient's body. Venous bridges are mostly taken from the great saphenous vein in the leg. This area is rich in blood vessels, and removing one does not affect the overall function, so the "bridge" blood vessels are mostly taken from here. When taking a venous bridge, lower limb surgical disinfection is an important part of ensuring the success of the operation.

[0003] When disinfecting the lower limbs in clinical practice, the patient usually lies on his back or side, and the medical staff lifts the heels of the anesthetized patient, and then another person disinfects the patient's legs. This method not only wastes manpower, but also the lifting personnel may cause the patient's limbs to slip due to physical exhaustion, which is very likely to cause harm to the patient. At present, in order to reduce labor costs and prevent limbs from slipping, hospitals often use an infusion stand plus a bandage suspension method instead of manual lifting. However, there are still the following shortcomings when using it: (1) There will be relative movement between the infusion stand and the operating table, and the patient's lower limbs will be unstable when suspended, causing the infusion stand to collapse easily. Therefore, an assistant is also required to hold the infusion stand, which wastes human resources; (2) The height of the suspended legs is not convenient to adjust. When the height is not appropriate, the legs need to be put down and the bandages need to be re-tied, which is very inconvenient to use and extremely wastes surgical time.

[0004] In summary, there is an urgent need to design a lower limb disinfection suspension frame that overcomes the above-mentioned problems. Utility Model Content

[0043] The two opposite sides of the two uprights 1 are also provided with mutually symmetrical fixing components 4, which are detachably connected to the two sides of the operating bed, so as to avoid relative movement between the device and the operating bed and cause collapse, thereby improving the stability of the device when in use.

[0044] A pair of fixing rings 5 ​​are provided on both sides of the lower end of the cross bar 3. When in use, the two ends of the bandage are tied to the paired fixing rings 5, so that the patient's legs are suspended, which is convenient for doctors to perform preoperative disinfection. The upper ends of each fixing ring 5 are fixedly connected to a drawstring 6, and the two vertical poles 1 are provided with a drawstring reeling mechanism 7. The two drawstrings 6 at the upper ends of each pair of fixing rings 5 ​​are respectively inserted from the inside of the cross bar 3 and the vertical pole 1 and connected to the drawstring reeling mechanism 7, so that the drawstring reeling mechanism 7 can control the reeling of the drawstring 6, thereby adjusting the height of the fixing ring 5, and then achieving the purpose of adjusting the height of the patient's legs. When adjusting, there is no need to put down the legs and re-tie the bandage, which is convenient to operate. The drawstring reeling mechanism 7 is also provided with a locking mechanism 8. The locking mechanism 8 can lock the drawstring reeling mechanism 7, which effectively prevents the drawstring from being randomly reeled under gravity or a large pulling force, making the device more stable when in use.
