Stick the distance label on the head of the tube body, and there will be a distance mark for ultrasound imaging at a specific distance from the head of the tube body, and the distance from the head of the tube body into the heart can be clearly and accurately displayed by ultrasound, so that Judgment distance.

Description

A delivery sheath tube distance label

technical field

The utility model relates to a medical device, in particular to a distance label for a delivery sheath tube.

Background technique

In cardiac surgery, when intracardiac surgery is performed, a delivery sheath is often required to deliver specific surgical instruments. For example, when performing ultrasound-guided atrial septal defect occlusion, it is necessary to use a delivery sheath to deliver the fan into the heart. When conventional delivery sheaths are used, the distance of the front end of the sheath extending into the heart must be judged by the doctor's estimation, especially for young children's hearts, the small operation distance brings great trouble to the operation. Therefore, how to accurately judge the distance that the delivery sheath extends into the heart has become a technical problem.

Contents of the invention

The utility model provides a delivery sheath tube distance label, which can accurately determine the distance of the delivery sheath extending into the heart by pasting it on the delivery sheath tube. In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical means:

A delivery sheath tube distance label, comprising an adhesive tape; a strip-shaped metal film is fixedly arranged at a specific distance on the adhesive tape.

The adhesive tape is rectangular, and its width is equal to the perimeter of the delivery sheath body; the metal film is longitudinally arranged on the adhesive tape;

1, 2 or 3 metal thin films are respectively arranged on the adhesive tape at a distance of 1 cm, 2 cm or 3 cm from the front end.

The beneficial effect of the utility model is that: when the distance label is pasted on the head of the tube body, there will be a distance mark for ultrasonic development at a specific distance from the head of the tube body, and the distance of the head of the tube body extending into the heart can be determined by ultrasound. Clear and accurate display, so that the distance can be accurately judged.

detailed description

Below in conjunction with the accompanying drawings, a preferred embodiment of the distance label for the delivery sheath of the present invention will be described in detail:

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the main body of the delivery sheath distance label is a rectangular adhesive tape 22 , and the width of the adhesive tape 22 is equal to the circumference of the tube body 1 of the delivery sheath. On the adhesive tape 22, 1 cm, 2 cm or 3 cm from the front end, 1, 2 or 3 metal films 32 are vertically arranged respectively, and the metal films 32 are fixed on the adhesive tape 22 side by side, and the length of each metal film 32 is It is equal to the width of the adhesive tape 22 and aligned with the broad side of the adhesive tape 22 .

The width of the metal film 32 is 1 mm, so that at a distance of 1 cm, 2 cm or 3 cm from the front end of the adhesive tape 22, the width of the metal film 32 is 1 mm, 2 mm or 3 mm, respectively.

When in use, align the front end of the adhesive tape 22 with the front end of the delivery sheath head 2 before the operation and stick it on the head 2, so that there is one strip at 1 cm, 2 cm or 3 cm from the front end of the head 2. , distance marks 3 of different widths composed of 2 or 3 metal thin films 32 . After the delivery sheath is inserted into the heart, the distance of the sheath extending into the heart can be judged only according to the width of the distance mark 3 on ultrasound imaging. Since the distance label of the delivery sheath is prepared in advance, it is only necessary to stick the adhesive tape 22 on the head 2 of the delivery sheath before the operation, so that there is no need to design and modify the existing delivery sheath, which reduces the production cost .
