A fixation device for brachial artery puncture point

technical field

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

Background technique

At present, endovascular surgery has become the first choice for the treatment of vascular lesions. The femoral artery is currently the most commonly used puncture site for peripheral vascular interventional therapy, but there are still many patients who need to complete the operation through the brachial artery approach, especially the fenestration and chimney surgery for aortoiliac artery occlusive lesions and aortic lesions. According to literature reports, the incidence of complications at the brachial artery puncture site is about 3%, and compared with femoral artery site complications, the consequences of hematoma or pseudoaneurysm in the brachial artery are more serious, which can lead to nerve entrapment and anterior aneurysm. Mural compartment syndrome, poor prognosis. The diameter of the brachial artery is relatively small, and a vascular closure device cannot be used like the femoral artery. At present, the commonly used method is still to use manual compression for about 10 minutes and bandage for 24 hours. But the most important thing in the whole process is that the patient needs to keep the entire forearm and upper arm in a straight state. For anesthetized patients and patients who have fallen asleep, it is difficult to maintain this position, which relatively increases the risk of complications of puncture surgery. At present, for how to keep the patient's entire forearm and upper arm in a straight state, the main solution is to fix the patient's elbow joint with a restraint belt, but it still cannot completely eliminate the patient's limb movement. Therefore, the technical field urgently needs a simple and effective brachial artery puncture point fixing device to solve the technical problem of how to keep the entire forearm and upper arm in a straight state during the brachial artery access operation.

Contents of the invention

The purpose of this utility model is to solve the technical problem of how to obtain a simple and effective fixing device for brachial artery puncture point so that the patient can keep the whole forearm and upper arm in a straight state during brachial artery surgery.

In order to achieve the purpose of solving the above problems, the technical solution adopted by the utility model is to provide a fixing device for the brachial artery puncture point, including an upper splint, a lower splint and a nylon fixing belt; the upper splint and the lower splint are in the shape of a cuboid, with The same length, width and thickness; the two sides of the lower splint close to one third of one end are respectively provided with a nylon fixing belt, and the two sides of the lower splint close to the third of the other end are also respectively provided with a nylon fixing belt.

Preferably, the length of the upper splint and the lower splint is 15cm.

Preferably, the width of the upper splint and the lower splint is 5cm.

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

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

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

①The utility model adopts the design of the rigid foam splint to make the device more flexible, which will not cause ischemia in the distal limbs, and has a good buffering effect;

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

Detailed ways

In order to make the utility model more obvious and understandable, the preferred embodiment is hereby described in detail in conjunction with the accompanying drawings as follows:

As shown in Figure 1-3, the utility model provides a kind of fixation device of brachial artery puncture point, comprises upper splint 1, lower splint 2 and nylon fixing belt; Length, width and thickness; the two sides of the lower splint 2 near one third of one end are respectively provided with a nylon fixing belt, and the two sides of the lower splint near the third of the other end are also respectively provided with a nylon fixing belt. The length of upper splint 1 and lower splint 2 is 15cm. The width of upper splint 1 and lower splint 2 is 5cm. The thickness of the upper splint 1 and the lower splint 2 is 0.5cm; the upper splint 1 and the lower splint 2 are made of rigid foam material.

Example

The utility model provides a fixing device for a brachial artery puncture point, which is composed of two cuboid hard foam splints with the same volume and size. The upper splint 1 and the lower splint 2 are both 15cm in length, 5cm in width, and 0.5cm in height (as shown in Figure 1), and are placed above and below the elbow with the patient's elbow as the center. The upper splint 1 is placed on the top, and the lower splint 2 is placed below to clamp the patient's elbow in the middle. The lower splint 2 is provided with 4 nylon fixing straps (10 cm long) of the same length. Nylon fixing belt one 3, nylon fixing belt two 4, nylon fixing belt three 5 and nylon fixing belt four 6 are respectively fixed on the both sides of lower splint 2. During use, the nylon fixing belt 1 3 and the nylon fixing belt 2 4; the nylon fixing belt 3 5 and the nylon fixing belt 4 6 are respectively wound around the top of the upper splint 1 and tied up, so that the upper splint 1 and the lower splint 2 cover the patient's entire forearm Fix it together with the upper arm; the tightness of the binding depends on the weakening but not disappearance of the distant radial artery pulse. As shown in Figure 2, it is a side view of the device, and the distance between the nylon fixing belt and the edge of the splint is 5 cm. Fig. 3 is the splint figure of top view, and nylon fixing band is respectively fixed on the both sides of splint.

The device first utilizes the foam material with a certain hardness to fix the elbow well, has a good cushioning effect, has a certain elasticity, and can greatly reduce the risk of ischemia in the distal limb. And the design of the nylon fixing belt can make the device compatible with the diameters of limbs of different patients.

The use process of the utility model:

① After the patient has completed the interventional operation of the brachial artery approach, remove the sheath, press the puncture point for 10 minutes, and wrap it with a bandage;

② One person assists in lifting the patient's affected limb horizontally, ensuring that the palms of the hands are facing upwards and the elbow cannot be bent. Place the lower splint 2 of the above device below the patient's elbow, and place the upper splint 1 above the elbow. Respectively tie the nylon fixation belt around both sides of the patient's elbow above the upper splint 1;

③Place the patient's affected limb on a horizontal bed, and adjust the tightness of the nylon fixing belt to ensure that the elbow cannot be easily bent, and the pulse of the distal radial artery is weaker than before bandaging but does not disappear;

④ After 24 hours of compression, untie the nylon fixing band and remove the bandage, observe whether there is bleeding at the puncture point of the patient's elbow, and whether the pulse of the distal radial artery returns to normal.

The above description is only a preferred embodiment of the present utility model, and is not any formal and substantial limitation of the present utility model. Several improvements and supplements can also be made, and these improvements and supplements should also be regarded as the protection scope of the present utility model.
