Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a lower limb restraint device after IABP surgery. Background Art

[0002] IABP should be called Intra-aortic balloon pump, which refers to intra-aortic balloon pump. IABP is a common medical method of mechanical circulatory assistance in clinical practice. Specifically, it refers to implanting a balloon-carrying catheter in the arterial system into the descending aorta at the distal end of the opening of the left subclavian artery and above the opening of the renal artery. The balloon is inflated immediately after the aortic valve closes in the early stage of diastole. Most of the blood flows retrogradely upward to increase the pressure of the aortic root, increase the blood perfusion of the brain and coronary arteries, and a small part of the blood flow is squeezed to the lower limbs and kidneys, slightly increasing peripheral perfusion. The balloon is quickly deflated before the aortic valve opens during systole, producing a "cavitation" effect, reducing the heart afterload, the left ventricular end-diastolic volume and ventricular wall tension, reducing cardiac work and myocardial oxygen consumption, and increasing cardiac output by 10% to 20%. IABP can increase the intra-aortic diastolic pressure, increase coronary blood supply and improve myocardial function. It has been widely used in the rescue and treatment of critically ill patients such as heart failure.

[0003] Many IABP tubes are placed on the thigh. Patients who are treated with IABP must stay in bed, supine or semi-recumbent with an angle less than 45 degrees. The lower limb on the side where the IABP is placed should be straightened to avoid knee and hip flexion. In order to prevent the patient's lower limbs from moving, a restraint belt is often used to restrain the ankle joint, and the other end of the restraint belt is connected to the bed. Although this method has the effect of limiting the movement of the patient's lower limbs to a certain extent, the restraint belt is a flexible belt after all, and this method cannot effectively limit the patient's leg movement, and the patient's lower limbs can still shake and bend slightly.

[0004] Patent application number 201520107652.5 discloses a knee restraint belt, which is used to restrain the lower limbs of patients after IABP surgery. However, since the restraint belt is flexible, the patient's lower limbs can still shake and bend slightly. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2As shown, the IABP postoperative lower limb restraint device includes a fixing frame 1, a slider 2, a positioner 4 and a restraint frame 3; the fixing frame 1 can be fixed on the rear end of the bed 5, and the fixing frame 1 includes a fixing frame guide rail 12 arranged in the left and right directions; the slider 2 cooperates with the fixing frame guide rail 12 so as to be able to move left and right; the positioner 4 can limit the movement of the slider 2; the restraint frame 3 includes a restraint frame base plate 31 and at least two restraint belts 33, the restraint frame base plate 31 is arranged in the front-to-back direction and connected to the slider 2, and each restraint belt 33 is arranged at intervals in the front-to-back direction and connected to the restraint frame base plate 31.

[0028] When the utility model is used, Figure 1 and Figure 2 As shown, the utility model is fixed to the end of the bed 5 by the fixing frame 1, and the restraint frame 3 is placed on the bed 5; the patient's lower limbs are placed on the restraint frame bottom plate 31, and the patient's lower limbs are restrained on the restraint frame bottom plate 31 with the restraint belt 33, thus completing the restraint of the patient's lower limbs.

[0029] Although the present invention still uses the restraint belt 33, it is different from the prior art in that the restraint belt is not connected to the patient's ankle or knee at one end and connected to the bed 5 at the other end; instead, the patient's lower limbs are restrained on the restraint frame bottom plate 31. After the restraint device is installed, the restraint frame bottom plate 31 cannot move, and the patient's lower limbs restrained on the restraint frame bottom plate 31 cannot move or bend. Therefore, the present invention has a better effect of restricting the movement of the patient's lower limbs, which is conducive to ensuring the IABP treatment effect, thereby facilitating the patient's early recovery.

[0030] The slider 2 cooperates with the fixed frame guide rail 12 so that it can move left and right, and the restraint frame 3 is connected to the slider 2, so the restraint frame 3 can also move left and right. The significance of the restraint frame 3 moving left and right is that both lower limbs of the patient may undergo IABP surgery, and the position of the patient relative to the bed is difficult to determine after all. The restraint frame 3 can be moved and adjusted to adapt to the above situation. The positioner 4 is used to lock the slider 2 after the position of the restraint frame 3 is adjusted, thereby locking the restraint frame 3.

[0031] The specific structure of the fixing frame 1 is as follows: Figures 1 to 6 As shown, the fixed frame 1 includes a first fixed end frame 11, a second fixed end frame 13, a guide rail end plate 14 and a fixed frame clamping bolt 15. The first fixed end frame 11 and the guide rail end plate 14 are respectively connected to the two ends of the fixed frame guide rail 12, and the second fixed end frame 13 cooperates with the fixed frame guide rail 12 so as to be able to move left and right. The first fixed end frame 11 is provided with a first bed side groove 112 and a first rear bed stop groove 113, and the second fixed end frame 13 is provided with a second bed side groove 132 and a second rear bed stop groove 133. The fixed frame clamping bolt 15 is connected to the guide rail end plate 14 and can tighten the second fixed end frame 13.

[0032] When installing the restraint device, place it at the tail of the bed 5, loosen the fixing frame clamping bolt 15, move the second fixing end frame 13 to increase the distance between the second fixing end frame 13 and the first fixing end frame 11. Then clamp the first fixing end frame 11 at the tail of the bed 5, insert the edge of the bed board 51 into the first bed side groove 112, and insert the edge of the rear bed guard 52 into the first rear bed guard groove 113. Then tighten the fixing frame clamping bolt 15, push the second fixing end frame 13 toward the bed 5, until the second fixing end frame 13 is clamped at the tail of the bed 5, the edge of the bed board 51 is inserted into the second bed side groove 132, and the edge of the rear bed guard 52 is inserted into the second rear bed guard groove 133. In this way, the fixing frame 1 is fixed on the bed 5, and the restraint device is installed. The groove on the fixing frame 1 embedded in the bed part and the clamping effect of the fixing frame clamping bolt 15 can better limit the movement and swing of the restraint device.

[0033] The fixed frame guide rail 12 is used to guide the movement of the slider 2 and the second fixed end frame 13. The specific structure thereof can be: the fixed frame guide rail 12 includes two guide rods 121 arranged in parallel, and the slider 2 and the second fixed end frame 13 are both sleeved on the two guide rods 121.

[0034] In order to further improve the fixing stability of the restraint device, it is preferred that the widths of the first bed side groove 112, the first rear bed stop groove 113, the second bed side groove 132 and the second rear bed stop groove 133 are all adjustable. A specific method may be to set two first knobs 111 on the first fixed end frame 11. The first bed side groove 112 and the first rear bed stop groove 113 are formed between the surface of the first knob 111 and the surface of the first fixed end frame 11 opposite to it. By turning the first knob 111 to adjust the position, the widths of the first bed side groove 112 and the first rear bed stop groove 113 can be adjusted to match the hospital bed 5. The width adjustment method of the second bed side groove 132 and the second rear bed stop groove 133 is the same as that of the first bed side groove 112 and the first rear bed stop groove 113.

[0035] As mentioned above, the locator 4 is used to lock the slider 2 after the position of the restraint frame 3 is adjusted. Its specific structure can be: the locator 4 is a positioning pin, and a plurality of positioning holes 122 are arranged at intervals on any guide rod 121. The positioning pin is threadedly connected to the slider 2 and can be inserted into any positioning hole 122.

[0036] IABP has many pipelines and devices such as double-lumen balloon catheter, power supply, drive system, monitoring system, adjustment system, trigger system, etc. At present, these pipelines and devices are generally placed on the bed, which is quite messy. In order to be more neat and standardized, it is preferred that the restraint frame 3 includes two storage slots 34, which are respectively located on the left and right sides of the restraint belt 33 and connected to the restraint frame bottom plate 31. In this way, the above pipelines and devices can be placed in the storage slots 34 to avoid clutter.

[0037] In order to make the patient more comfortable, the restraint frame 3 preferably includes a flexible pad 32, and the flexible pad 32 is connected to the restraint frame bottom plate 31. The flexible pad 32 can be a common flexible pad.

[0038] The utility model is roughly T-shaped when in use, and occupies a large space. The following configuration can be made: one side of the restraining frame 3 is hinged to the slider 2, and the other side is connected to the slider 2 through a fastener; when the fastener is loosened, the restraining frame 3 can rotate to be set in the same direction as the fixed frame guide rail 12.

[0039] Thus, when the utility model is not in use, it can be Fig. 9 As shown, loosen the fasteners and rotate the restraining frame 3 to be arranged in the same direction as the fixing frame guide rail 12, which can reduce space occupation and facilitate storage.
