[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a limb fixation device for postoperative nursing of coronary intervention via the femoral artery. Background Art

[0002] After coronary artery intervention, some patients will be transferred to the cardiac care unit (CCU) for observation for a period of time before being transferred back to the general ward. Patients who complete interventional treatment via femoral artery puncture need to lie flat for 24 hours after the catheter is removed, and keep the lower limb on that side absolutely straight for 24 hours. The surgical wound will also be bandaged with gauze bandages for pressure to avoid local hematoma and pseudoaneurysm formation.

[0003] After the existing coronary artery intervention, the patient's ankles and the bed are usually fixed with ropes to keep the patient's legs straight. However, this fixing method is not only cumbersome, but also makes it impossible for the patient to turn over. Lying flat for a long time will cause back pain in the patient, which has a certain impact on the patient's physical health.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example, reference Figures 1 to 5 .

[0030] A semi-cylindrical groove 8 is provided on the side wall of the lower mounting block 2 and the upper mounting block 3. One side of the lower mounting block 2 is connected to the upper mounting block 3 by a hinge 5, and the axis of the hinge 5 is parallel to the axis of the groove 8. The deflation valve is installed on the upper mounting block 3 and the lower mounting block 2 by bolts, and the deflation valve is connected to the inflatable cushion 4. A control switch for controlling the deflation valve is installed on the upper mounting block 3 by bolts. Medical staff can determine the time point when the inflatable cushion 4 stops inflating according to the patient's feedback. When it is necessary to release the fixation of the patient's lower limbs, the pressure of the inflatable cushion 4 can be restored to be equal to the atmospheric pressure through the deflation valve. The inflatable cushion 4 can better fit the patient's legs and adjust itself according to the patient's leg shape, thereby improving the patient's comfort and the practicality of the limb fixation device for postoperative care of coronary intervention via the femoral artery.

[0031] The mounting rod 6 is vertically bolted to the side of the lower mounting block 2 away from the groove 8, and the clamping block 7 is welded to the end of the mounting rod 6 away from the lower mounting block 2. The bed 1 is provided with a mounting hole 9, and a limiting groove matching the clamping block 7 is provided at the bottom of the mounting hole 9, and the mounting rod 6 and the mounting hole 9 are clearance-matched. The mounting rod 6 is inserted into the mounting hole 9, and when the bottom of the lower fixing block contacts the bed 1, the lower fixing block is rotated 90°, and the limiting groove will limit the clamping block 7 in the vertical direction, thereby preventing the patient from moving it and causing the patient's lower limbs to be inconsistent with the upper body.

[0032] A slide groove 12 is provided on the surface of the groove 8, and the arc slider 11 is installed on the outer diameter side wall of the semi-cylinder 10. The semi-cylinder 10 is installed on the groove 8 by the cooperation and rotation of the arc slider 11 and the slide groove 12. An inflatable cushion 4 is installed on the inner diameter surface of the semi-cylinder 10. When the upper mounting block 3 and the lower mounting block 2 are fitted, the two slide grooves 12 are merged into a circular slide groove 12. When the patient turns over, the lower limbs will drive the semi-cylinder 10 to rotate on the slide groove 12, thereby ensuring the consistency of the lower limbs and the upper body. Generally, the patient's turning over will cause the semi-cylinder 10 to rotate 90°, because the slider originally located in the slide groove 12 of the upper fixed block will enter the slide groove 12 of the lower fixed block. In order to allow the slider to better enter the slide groove 12, both ends of the slider are chamfered. When the slider is located in the slide grooves 12 of the upper and lower fixing blocks at the same time, the upper and lower fixing blocks cannot be opened. Therefore, when the upper and lower fixing blocks need to be opened, the patient needs to be restored to a lying position so that the slider is located in the respective initial slide grooves 12. The utility model makes the center angle of the slider smaller than the center angle of the slide groove 12, thereby retaining some error margins, and there is no need to completely align the slider with the slide groove 12, thereby improving the convenience of use of the limb fixation device for postoperative care of coronary artery intervention via the femoral artery.

[0033] The edges of the upper mounting block 3 and the lower mounting block 2 are provided with rounded corners to prevent the patient from being scratched. The bed 1 is provided with a mounting groove 13, and the mounting hole 9 is provided at the bottom of the mounting groove 13. The depth of the mounting groove 13 is equal to the minimum distance from the inflatable cushion 4 on the lower mounting block 2 to the mounting rod 6. The lower limbs of the patient are flush with the bed 1 to prevent the lower limbs of the patient from being partially suspended in the air, causing discomfort.

[0034] The bed 1 is symmetrically provided with mounting grooves 13, and a plurality of mounting holes 9 are provided in a linear array along the long side of the bed 1 in the mounting grooves 13. The limb fixation device for postoperative care of coronary intervention via the femoral artery can be installed at multiple positions on the bed 1, and is conveniently adjusted to a position suitable for the patient, thereby improving the practicality of the limb fixation device for postoperative care of coronary intervention via the femoral artery.

[0035] The connecting plate 14 is installed on the side of the lower mounting block 2 away from the hinge 5. The connecting plate 14 is provided with a locking hole 22. The upper mounting block 3 is provided with a connecting hole 18 that matches the connecting plate 14. A through hole 19 is provided on the side wall of the connecting hole 18 close to the groove 8. The semi-cylinder 10 is provided with a notch 20 at a position relative to the through hole. The locking block 17 is slidably installed in the through hole 19. The end of the locking block 17 away from the connecting hole 18 is provided with a pressing plate 15. The two ends of the spring 16 are elastically supported against the pressing plate 15 and the groove 8 respectively. When the inflatable cushion 4 is inflated, the pressing plate 15 will be pushed to squeeze the spring 16, thereby driving the locking block 17 to enter the locking hole 22 to lock the connecting plate 14; when the inflatable cushion 4 is deflated, the spring 16 will push the locking block 17 to leave the locking hole 22 to unlock. The locking unit can prevent the medical staff from opening the upper fixing block without deflation, and the expansion force of the inflatable cushion 4 can cause the upper fixing block to rotate rapidly, thereby causing damage to the upper fixing block or injury to people.

[0036] A pressure sensor is installed in the semi-cylinder 10, and the pressure sensor is electrically connected to the deflation valve. When the pressure sensor reaches the set value, the deflation valve is activated to ensure the stability of the pressure of the inflatable cushion 4, so as to avoid excessive pressure on the inflatable cushion 4 and excessive compression of the patient's lower limbs. The bottom of the mounting hole 9 is connected to the end of the mounting rod 6 away from the lower mounting block 2 by contact power supply, so as to provide power for the pressure sensor and the deflation valve.

[0037] An arc-shaped plate 21 is installed on one side of the upper mounting block 3 away from the groove 8. The arc-shaped plate 21 is covered with soft materials, such as sponge, latex and rubber, etc., to facilitate the patient to place the other lower limb.

[0038] In summary, medical staff will install the limb fixation device for postoperative care of coronary intervention via the femoral artery on the bed 1, then open the upper fixing block and the lower fixing block, place the knee part of the patient's lower limbs on the inflatable cushion 4, and then close the upper fixing block and the lower fixing block, and inflate the inflatable cushion 4 with a portable air pump. At this time, the locking unit will prevent the upper fixing block and the lower fixing block from opening, thereby completing the straightening and fixation of the patient's lower limbs.
