Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a wearable femoral artery perfusion limb fixation device and a use method thereof. Background Art

[0002] Hepatic artery infusion chemotherapy is not a new liver cancer treatment technology. It has been used since the 1970s and 1980s. At that time, the infusion of chemotherapy drugs was mainly completed through surgical hepatic artery catheterization or intravascular intervention technology. Compared with systemic chemotherapy, infusion of chemotherapy drugs in the hepatic artery can increase the local drug concentration in the tumor tissue and reduce the distribution of chemotherapy drugs in other organs, thereby producing a stronger anti-tumor effect and reducing systemic side effects.

[0003] There are some shortcomings in the existing methods of fixing the catheter:

[0004] 1. In the prior art, the insertion tube is usually fixed directly on the patient's skin by a film, and then three catheters extend outward from the insertion tube fixed on the skin. The catheters are prone to become scattered after a long time of use, resulting in the incorrect use of the catheters in the later stage. In addition, the catheters are prone to slippage and pulling;

[0005] 2. The patient's lower limbs are prone to excessive movement after surgery. When the angle of the patient's hip joint is too large, the femoral artery perfusion catheter may bend and cause displacement, blockage, and breakage of the catheter.

[0006] In view of the above problems, the present invention document proposes a wearable femoral artery perfusion limb fixation device and a method of using the same. Summary of the invention

[0058] Example 2

[0059] refer to Figure 8 and Fig. 9, an improvement on the basis of Example 1: a receiving plate 48 is fixed on one side of the back plate 3, and two bidirectional screw rods 49 are connected to the internal thread of the receiving plate 48, and the two bidirectional screw rods 49 are welded and fixedly connected at one end close to each other, and one end of one bidirectional screw rod 49 extends to the outside of the receiving plate 48, and nut blocks 50 are threadedly sleeved on the positive and negative thread sections of the two bidirectional screw rods 49, and the nut blocks 50 slide in the receiving plate 48, and one side of the two nut blocks 50 is rotatably connected to a plurality of connecting rods 51, and one end of the plurality of connecting rods 51 is rotatably connected It is connected to the same drag plate 52, and the drag plate 52 slides in the storage plate 48; when the user lies on the bed, the user's waist is in a stress-free state, and the user's waist is tired. At this time, the bidirectional screw rod 49 is rotated, and the bidirectional screw rod 49 drives the two nut blocks 50 to move toward the middle, and the nut block 50 pushes the drag plate 52 out of the storage plate 48 through the connecting rod 51. The cooperation of the drag plate 52, the connecting rod 51 and the nut block 50 can lift the user's waist, bring comfort to the user, and avoid the user's waist fatigue caused by lying in bed for a long time.

[0060] A method for using a wearable femoral artery perfusion limb fixation device comprises the following steps:

[0061] S1. Fix the side panels 4 and the back panel 3 by the first bolts 5, fix the U-shaped frame 11 and the back panel 3 by the third bolts 12, and the U-shaped frame 11 further fixes the side panels 4. At this time, the back panel 3, the side panels 4 and the U-shaped frame 11 form a waist circumference 1, which is put on the user's waist, the first binding belt 6 passes through the first buckle 10 and is folded back, and the waist circumference 1 is bound to the user's waist by the cooperation of the second magic belt 9 and the first magic belt 8, and the U-shaped leg binding plate 18 is put on the user's thigh position, and the U-shaped leg binding plate 18 is a certain distance away from the thigh root, the second binding belt 20 passes through the second buckle 23 and is folded back, and the third magic belt 21 and the fourth magic belt 22 cooperate to tightly bind the U-shaped leg binding plate 18 to the user's leg;

[0062] S2. After controlling the distance that the first slide bar 29 slides up and down on the first protrusion 13, the first slide bar 29 is fixed to the first protrusion 13 by the fourth bolt 30. After controlling the distance that the sixth bolt 35 slides on the second protrusion 19, the second slide bar 33 is fixed to the second protrusion 19 by the fifth bolt 34. Then, the second slide bar 33 is sleeved on the second screw rod 38, and the second slide bar 33 is limited by the second fastening nut 47. When the user's lower limbs move, the legs drive the second slide bar 33 to rotate through the leg circumference 2, and the second slide bar 33 drives multiple pins 44 to rotate. The stopper 43 just limits the pins 44, controls the range of the user's activities (the range of activities is 10°-20°), and avoids excessive user activities that cause pipeline displacement and pipe blockage.

[0063] S3. When the range of motion needs to be adjusted, the first fastening nut 41 is rotated, and the first fastening nut 41 drives the inner gear ring 40 to move outward, and the inner gear ring 40 releases the brake on the fixed gear 39, and drives the plurality of stoppers 43 to rotate through the fixed disk 42, and controls the angle of the stoppers 43 to the pin 44. Then, the first fastening nut 41 is tightened, and the inner gear ring 40 limits the fixed gear 39 again, and then the fixed disk 42 can be fixed, so as to control the range of motion of the user;

[0064] S4, clamp the mounting plate 24 at the top of the U-shaped leg restraint plate 18, insert the clamping block 26 into the clamping groove 27, the cushion block 28 conflicts with the second slide bar 33, and fix the cushion block 28 and the second slide bar 33 by the sixth bolt 35, so as to fix the mounting plate 24. At this time, the mounting plate 24 is located at the hip joint, and then the catheter is passed through the multiple guide plates 25 from bottom to top in sequence, so that the catheter can be fixed, which not only prevents the catheter from being scattered, but also prevents the catheter from slipping and pulling;

[0065] S5. When the user lies on the bed, the waist of the user is in a state of no stress, and the user's waist is tired. At this time, the bidirectional screw rod 49 is rotated, and the bidirectional screw rod 49 drives the two nut blocks 50 to move to the middle. The nut block 50 pushes the drag plate 52 out of the storage plate 48 through the connecting rod 51. The cooperation of the drag plate 52, the connecting rod 51 and the nut block 50 can lift the user's waist, bring comfort to the user, and avoid the user's waist fatigue caused by lying in bed for a long time.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
