Abstract

The pads consist of a solid base pad (1), washable, made of non-X-ray contrast material, smooth surface, without sharp edges, consisting of a base (2) and a side wall (3) that closes with the base (1) right to obtuse angle α (4 ) and from at least two cylindrical pads (5) with a 8 to 22 cm diameter made of washable, partially pliable material. Advantageously, they consist of a square oblong pad (6) 10 to 15 cm wide and 5 to 10 cm high made of washable, partially pliable material.

Description

Set of pads for catheterization from the left radial artery

Field of technology

The technical solution refers to a set of pads enabling the performance of catheterization procedures on the heart and other arteries from the left radial artery.

Current state of the art

Until now, catheterization procedures on the heart and other arteries have been performed standardly, which means in about 90% of cases, through access through the right femoral artery from the groin. Catheterization procedures through groin access are associated with the necessity of subsequent immobilization of the patient and with a non-negligible risk of subsequent bleeding complications at the point of injection into the artery. Statistically, such subsequent serious bleeding complications occur in 2 to 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 performed from the right wrist 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 used based on the standard design of the angiographic devices on which the procedures are performed. The position of the doctor performing the catheterization procedure is on the right side of the patient against a system of monitors that are always suspended to the left above the lying patient. However, for right-handed patients, who make up 90% of the population, immobilizing their dominant hand immediately after the procedure is disadvantageous. It would therefore be advantageous to perform most of the catheterization procedures from the left radial artery.

Two facts prevent the routine performance of catheterization procedures from the left radial artery. One of them is the large distance between the catheterizing doctor and the patient's left hand, if it is placed on the left side of the patient's body, because the doctor performing the catheterization procedure must always stand on the right side of the patient during the procedure. The second 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 ensure a firm fixation of the left wrist during the procedure and thus the standard execution of catheterization.

The essence of the invention

The set of pads for catheterization from the left radial artery according to the invention, which is made up of one solid, washable base pad, largely eliminates the mentioned shortcomings. of X-ray non-contrast material, smooth surface, without sharp edges, consisting of a base, 0.6 cm thick, with dimensions of width 40 cm and length 40 cm and sides 20 cm high, forming a right to obtuse angle with the base and and of at least two cylindrical pads with a diameter of 8 to 22 cm made of washable, partially flexible material.

The side of the base pad can be provided with an oblique cut, viewed from the side opposite to the angle a, from half its height on the left to half its length on the top.

In addition, the set of pads for catheterization from the left radial artery can be supplemented with a square oblong pad 10 to 15 cm wide, 5 to 10 cm high, made of washable, partially pliable material.

The advantages of being able to operate using catheterization from the left wrist artery are enormous for large numbers of procedures. They bring benefits to patients, when the procedure becomes essentially outpatient. It is not only about reducing the time when the patient is out of the work process and receiving sick benefits, but

Clarification of drawings

The set of pads for catheterization from the left radial artery according to the invention can be seen from the attached pictures, in which the individual pads are simplified in an axonometric view. Figure 1 shows a solid washer, Figure 2 shows a cylindrical washer, and Figure 3 shows a rectangular oblong washer.

An example of the implementation of the invention

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

Fig. 1 shows a fixed pad 1. It consists of a base 2 and a side 3, forming an obtuse angle a 4 with the base 1. This angle a 4 is 120° in our particular case. The rigid pad 1 is made of 0.6 cm thick copolyester Pet-G material intended for bending and shaping. Base 2 measures 40 cm wide and 40 cm long. Side 3 has a height of 20 cm and a length of 40 cm. An oblique cut 7 is marked on the side 3, where the slanting of the upper part of the side 3 allows better access to the patient's left wrist in some cases. The oblique section 7 is, viewed from the opposite side to the angle a 4, taken from half of its height on the left to half of its length at the top.

Fig. 2 shows a cylindrical washer 5, two or three of which can be used, as needed. These mats are 40 cm long, 10, 15 and 20 cm in diameter. They are made of foam material sewn into a smooth textile canvas with a washable outer surface.

Fig. 3 shows a rectangular oblong pad 6, length 40 cm, width 10 cm and height 5 cm. It is again made of foam material sewn with upholstery into a textile canvas with a washable outer surface. This pad is used only in cases where the angiographic table on which the patient lies during the procedure has a softening layer on its surface under the patient that is too high and the bent part of the fixed pad 1 would not create sufficient support for the cylindrical pad 5.

The work with the set of pads for catheterization from the left radial artery according to the invention consists in the fact that the first pad 1 is inserted under the patient, with the bent part facing away from the patient. The depth of insertion is governed by the constitution of the patient. The solid pad 1 thus creates a stable foundation for the use of other pads.

Subsequently, cylindrical pads 5 are placed, which are placed in number and size as needed between the patient's left arm and elbow and the side 3 of the fixed pad L. This creates a stable support for the patient's left upper limb, which allows the left wrist to be placed near the right groin to the area between the umbilicus and the right groin, and thus handle the catheterization material during the procedure in the same way as when performing the procedure from the right groin.

Catheterization performed in this way is much gentler for the patient and allows him to return to full-fledged normal activities much sooner. This fact stands out all the more with the statistical data of 5,000 catheterization procedures performed annually/1 million inhabitants, 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.
