Description

A plastic applicator for ECMO catheters

technical field

The utility model belongs to the field of medical equipment, in particular to a plastic film sticking device specially used for ECMO catheters.

Background technique

Extra-corporeal Membrane Oxygenation (ECMO) is a medical emergency equipment. Its principle is to draw venous blood from the body out of the body and inject it into the patient's arterial or venous system after artificial heart-lung bypass oxygenation with special materials. Part of the cardiopulmonary replacement effect, maintaining the oxygenated blood supply of human organs and tissues. In addition to temporarily replacing the patient's cardiopulmonary function and reducing the burden on the patient's cardiopulmonary, it can also buy more treatment time for medical staff.

The basic structure of ECMO includes intravascular cannula, connecting tube, power pump (artificial heart), oxygenator (artificial lung), oxygen supply tube, and monitoring system. The two intravascular catheters required for ECMO treatment are placed in the patient's arteries or veins. How to ensure the sterility of the puncture points of these two catheters is an important way to prevent hospital-acquired infections in ECMO patients. The current clinical use is to use Sterile film is used for local coverage, but some ECMO catheters have a relatively large diameter. If the film is not properly shaped (as shown in Figure 3, there is an unsealable part 14), the airtightness of the film will not only be damaged , increasing the risk of infection; at the same time, the catheter is in direct contact with the patient's skin. Due to the hard material of the ECMO catheter and the need to indwell it for a long time, many patients have local device-related pressure injuries clinically. To sum up, the plastic catheter placement of ECMO film is important. However, due to the large area of the ECMO film and the glue on one side, and the inconsistent diameter of the ECMO pipeline (the diameter of the puncture point is small, it becomes thicker and tapered), and the ability of the medical staff to stick the film is different. Sometimes it takes several hours to attach the film, which is time-consuming and labor-intensive. It is necessary to invent a special plastic film applicator for ECMO to solve the above problems.

Contents of the invention

In order to solve the above problems, the utility model discloses a plastic film applicator dedicated to ECMO catheters. The clamp structure is used to make the film and the catheter airtightly bonded, and the bonding part is left below to protect the skin. The structure is practical and the operation is convenient. Practical problems are solved and security is increased.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A plastic film applicator for ECMO catheters, including two clips with the same structure, the two clips are X-shaped and cross-connected in the middle, and the clips are tightening part, connecting part and hand-holding part from front to back. The cross-sectional shape of the tightening part is semi-circular, and the diameter of the tightening part increases from front to back. The outer layer of the tightening part is a hard shell, and the inside of the hard shell is made of soft cushion material. As for the tight piece, the connecting part is provided with a resilient piece.

Further, the hard shell of the tightening part is made of hard plastic or metal, and the inside is made of rubber material.

Further, the hard shell of the tightening part is glued to the inside.

Further, the height of the clamping piece is 1 cm.

Further, the connecting parts are hinged through pin shafts.

Further, the handle is provided with a ring.

Further, anti-slip protrusions are provided inside the finger ring.

The beneficial effects of the utility model are:

A plastic film applicator dedicated to ECMO catheters described in the utility model adopts a clamp structure, and the inside is tapered, so that the film and the catheter are hermetically bonded. Increase the airtightness of the film and the catheter, and at the same time, the bonding part is located between the catheter and the skin to protect the skin. The structure is practical, the operation is convenient, the practical problem is solved, the efficiency is improved, and the safety is increased.

Detailed ways

The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model.

As shown in the figure, a plastic film applicator dedicated to ECMO catheters described in the present invention is in the shape of scissors (or clamps) as a whole, and is composed of two clamp bodies 1 that are symmetrically crossed and combined. From front to back, they are The tightening part 2, the connecting part 3 and the handle part 4, the cross-sectional shape of the tightening part 2 is semi-circular (two semicircles clamp the ECMO catheter 12), and the diameter of the tightening part becomes larger from front to back ( Correspondingly, the diameter of the ECMO catheter becomes thicker as it goes backwards), and in addition, a clamping piece 7 is provided under the tightening part 2. When the film 13 is placed on the ECMO catheter 12, hold the plastic film applicator described in the utility model and put The two tightening parts 2 are opened from the top of the membrane to clamp the membrane 13 and the ECMO catheter 12 completely, as shown in Figure 2, so that the membrane and the catheter are airtightly attached, and at the same time, the two clamping pieces 7 are clamped, so that the ECMO A fitting part with a height of 1cm is formed under the catheter 12. This part not only increases the airtightness of the film and the catheter, but also the fitting part is located between the catheter and the skin, so that the ECMO catheter 12 will not directly press on the skin and protect the skin. role.

The outer layer of the tightening part 2 described in the utility model is a hard shell 5, which can be made of hard plastic or metal material, which can ensure the pressure during shaping, so that the film and the catheter are hermetically bonded, and the hard shell 5 and the inner 6 soft pads The material is glued, and the cushion material can be made of rubber material, so as to ensure that the plastic film applicator can be airtightly matched with different types of catheters.

The connecting part 3 of the utility model is provided with a resilient member 8 (similar to the spring mechanism in the middle of the plastic spring clip), after the nurse manually clamps the membrane and the catheter, it will automatically open as soon as the hand is loosened, which is convenient and practical.
