Description

Fixing device for brachial artery puncture point

Technical Field

The utility model relates to a fixing device for a puncture point of a brachial artery, and belongs to the technical field of medical appliances.

Background

Endoluminal surgery has become the first modality of treatment for vascular lesions. The femoral artery is currently the most commonly used puncture site for peripheral vascular intervention, but many patients still need to complete surgery through brachial artery access, especially fenestration and chimney surgery of main iliac artery occlusion lesions and aortic lesions. The report in the literature indicates that the occurrence probability of the brachial artery puncture site complications is about 3%, and compared with the femoral artery puncture site complications, the brachial artery has hematoma or the result caused by the pseudo-aneurysm is more serious, so that the nerve entrapment and anterior wall bone fascial chamber syndrome can be caused, and the prognosis is poor. The brachial artery has a smaller diameter, and the vascular closer can not be used like the femoral artery, and the current common mode is still to use a mode of manually pressing for about 10 minutes and bandaging for 24 hours. But most importantly, the patient is required to keep the whole forearm and upper arm in a straightened state, and the posture is difficult to keep for anesthetized patients and patients after sleeping, thus the risk of complications of puncture operation is relatively increased. The main solution to the problem of how to keep the patient in a straightened state throughout the forearm and upper arm is to fix the patient's elbow joint with a restraining strap, but the patient's limb movements are still not completely eliminated. Therefore, there is a need in the art for a simple and effective brachial artery puncture site fixation device that addresses the technical problem of how to keep the entire forearm and upper arm in a straightened state during brachial artery access procedures.

Disclosure of Invention

In order to solve the above-mentioned problem, the technical scheme adopted by the utility model is to provide a fixing device of the puncture point of the brachial artery, comprising an upper clamping plate, a lower clamping plate and a nylon fixing belt; the upper clamping plate and the lower clamping plate are cuboid and are provided with the same length, width and thickness; two sides of the lower clamping plate, which are close to one third of one end, are respectively provided with a nylon fixing belt, and two sides of the lower clamping plate, which are close to one third of the other end, are respectively provided with a nylon fixing belt.

Preferably, the upper and lower clamping plates have a length of 15cm.

Preferably, the widths of the upper and lower clamping plates are 5cm.

Preferably, the thickness of the upper and lower clamping plates is 0.5cm.

Preferably, the upper and lower clamping plates are made of rigid foam material.

Compared with the prior art, the utility model has the following beneficial effects:

(1) the utility model adopts the design of the rigid foam splint to make the device more elastic, so that the device can not cause ischemia of the limb at the far end and has good buffering effect;

(2) the nylon fixing belt adopted by the utility model can be compatible with elbows of patients with different thicknesses.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments accompanied with the accompanying drawings are described in detail as follows:

as shown in fig. 1 to 3, the present utility model provides a fixing device for a puncture site of a brachial artery, comprising an upper splint 1, a lower splint 2 and a nylon fixing band; the upper clamping plate 1 and the lower clamping plate 2 are cuboid and are provided with the same length, width and thickness; two sides of the lower clamping plate 2 close to one third of one end are respectively provided with a nylon fixing belt, and two sides of the lower clamping plate close to the other third of the other end are respectively provided with a nylon fixing belt. The length of the upper and

lower clamping plates

1 and 2 is 15cm. The widths of the upper and

lower clamping plates

1 and 2 are 5cm. The thickness of the upper clamping plate 1 and the lower clamping plate 2 is 0.5cm; the upper clamping plate 1 and the lower clamping plate 2 are made of rigid foam materials.

Examples

The utility model provides a fixing device for a puncture point of a brachial artery, which consists of two cuboid rigid foam splints with the same volume. The upper splint 1 and the lower splint 2 are 15cm in length, 5cm in width and 0.5cm in height (as shown in figure 1), and are respectively arranged above and below the elbow of the patient with the elbow as the center. The upper splint 1 is placed above, the lower splint 2 is placed below, the elbow of the patient is clamped in the middle, and 4 nylon fixing belts (10 cm in length) with the same length are arranged on the lower splint 2. The nylon fixing belt I3, the nylon fixing belt II 4, the nylon fixing belt III 5 and the nylon fixing belt IV 6 are respectively fixed on two sides of the lower clamping plate 2. When in use, the nylon fixing belt I3 and the nylon fixing belt II 4 are connected; the nylon fixing band III 5 and the nylon fixing band IV 6 are respectively wound above the upper splint 1 to be tied, so that the upper splint 1 and the lower splint 2 fix the whole forearm and the upper arm of the patient together; the tightness of the binding is based on the weakening, but not the disappearance, of the radial artery pulsations in the distal region. The device is shown in figure 2 with a side view, the nylon fastening tape being 5cm from the edge of the splint. Fig. 3 is a view of the splint as seen from above, with nylon fixing bands respectively fixed to both sides of the splint.

The device firstly utilizes the foam material to fix the elbow well with certain hardness, has good buffer function and certain elasticity, and can greatly reduce the risk of remote limb ischemia. And the design of nylon fixed band can make this device compatible different patient's limbs's diameter.

The application process of the utility model comprises the following steps:

(1) after the interventional operation of the brachial artery access is finished, the sheath tube is pulled out, the puncture point is pressed for 10 minutes, and the puncture point is wrapped by a bandage;

(2) one assists in lifting the patient's affected limb horizontally, ensuring that the palm of the hand is up and the elbow cannot bend, placing the lower splint 2 of the above device under the patient's elbow, while placing the upper splint 1 above the elbow. Respectively tying nylon fixing belts above the upper clamping plate 1 by bypassing two sides of the elbow of the patient;

(3) the patient suffering from limb is put on the horizontal bed, the tightness of the nylon fixing belt is adjusted, the elbow is ensured not to be easily bent, and the distal radial artery pulsation is weakened but not disappeared before being wrapped;

(4) after 24 hours of compression, the nylon fixing band is untied, the bandage is removed, and whether the puncture point of the elbow of the patient has blood seepage or not is observed, and whether the radial artery pulse at the far end is recovered to be normal or not is observed.
