Description

Set of pads for catheterization from left radial artery.

Technical field

The invention relates to a set of mats enabling catheterization procedures to be performed on cardiac and other arteries from the left radial artery.

BACKGROUND OF THE INVENTION

Until now, catheterization procedures on cardiac and other arteries have been performed as standard, which means in about 90% of cases, access through the right femoral artery from the groin. Catheterization by access from the groin is associated with the need for subsequent immobilization of the patient and a significant risk of subsequent severe bleeding complications at the site after injection into the artery. Statistically, such subsequent severe bleeding complications occur in 2-4% of cases.

In the remaining cases, catheterization procedures on the heart and other arteries are performed through the radial artery from the right wrist. Procedures from the right wrist approach minimize the risk of bleeding complications, but are associated with subsequent immobilization of the patient's right hand. Access to the arteries from the right side of the patient is based on the standard design of the angiographic devices on which the procedures are performed. The position of the physician performing the »catheterization procedure is from the right side of the patient against a set of monitors, which are always suspended to the left above the lying patient. However, for right-handed patients, which are 90% of the population, immobilization of their dominant hand immediately after surgery is disadvantageous. Therefore, it would be advantageous to perform most catheterization procedures from the left radial artery.

The routine catheterization procedure from the left radial artery is prevented by two facts. One of them is too much distance between the catheterizing doctor and the left hand if it is placed to the left of the patient's body. The other is the possibility of placing the left hand over the patient's abdomen towards the right groin. However, this position of the left upper limb is very unstable in itself and cannot provide a firm fixation of the left wrist during surgery and hence standard catheterization.

SUMMARY OF THE INVENTION

These drawbacks are largely overcome by the left radial artery catheterization pad assembly of the present invention, which consists of a single, rigid, washable base, a non-contrast X-ray material, a smooth surface, with no sharp edges, consisting of a base and an obtuse angle of at least two cylindrical washers with a diameter of 8 to 22 cm from a washable, partially yielding material.

The side of the base pad may be provided with an oblique cut extending from nearer half height to upper half length.

In addition, the left radial artery catheterization pad assembly may be complemented by an angular elongated pad of 10-15 cm wide, 5-10 cm high, of a washable, partially yielding material.

Overview of the drawings

The set of mats for catheterization from the left radial artery according to the invention is apparent from the enclosed figures, in which the individual mats are shown in simplified axonometric view. Figure 1 shows a solid washer, Figure 2 shows a cylindrical washer, and Figure 3 shows a square elongated washer.

DETAILED DESCRIPTION OF THE INVENTION

A practical embodiment of a set of pads for catheterization from the left radial artery according to the invention is shown in the attached figures 1 to 3.

In FIG. 1, a fixed washer 1 is shown. It consists of a base 2 and a side 3 forming an obtuse angle α (4) with the base 1. Tentalhel α (4) is 120 ° in our particular case. The rigid support 1 is made of 0.6 cm Pet-G copolyester material for bending and forming. The base 2 has a width of 40 cm and a length of 40 cm. The side 3 has a height of 20 cm and a length of 40 cm. On the side 3 there is an oblique cut 7 where the sloping of the upper side 3 allows better access to the patient's left wrist at the start of the procedure. The bevel 7 is guided from half the upper length to half the closer height.

Figure 2 shows a cylindrical washer 5, which is selected for a given patient from an assembly of two or three washers of different diameters. The length of these washers proved to be 40 ·· Φ ··· cm, diameter ΙΟ, 15, and 20 cm. They are made of plastic foam sewn upholstery into a smooth rubber-textile cloth with washable outer surface.

Figure 3 shows a square elongated pad 6 with a length of 40 cm, a width of 10 cm and a height of 5 cm. It is again made of foam upholstery sewn into a smooth rubber-textile cloth with a washable outer surface. This pad is placed on the extended part of the base 2 of the solid pad 1 and is used only when the angiographic table on which the patient lies during surgery has a softening layer underneath the patient on its surface and the bent portion of the solid pad 1 would not provide sufficient support for cylindrical washer 5.

The work with the left radial artery catheterization pad assembly of the present invention consists in placing the rigid pad 1 under the patient with the bent portion away from the patient. The insertion depth depends on the patient's constitution. The rigid washer 1 thus provides a stable foundation for the use of other washers.

Subsequently, a cylindrical washer 5 is placed, the particular size of which is chosen according to the dimensions of the patient. It is placed between the left arm and the patient's elbow and the side 3 of the rigid pad 1. This creates a stable support for the left upper extremity of the patient, allowing placement and fixation of the left wrist near the right groin, or in obese patients . The handling of the catheter material during the procedure is then the same or very similar to that performed from the right groin.

Such catheterization maintains unrestricted mobility of the patient's right hand and thus minimizes, besides the risk of bleeding, the restriction of self-sufficiency immediately after the procedure. It allows the patient to return fully to his normal activities before other approaches. This fact is even more apparent in the statistical data on 5,000 catheterization procedures / 1 million inhabitants performed annually in the Czech Republic alone, of which 90% are right-handed.

Industrial applicability

The set of pads for catheterization from the left radial artery can be used in all medical facilities where catheterization procedures are performed.
