Description

A kind of venous catheter protective cover

technical field

The utility model relates to the technical field of medical instruments, in particular to a protective cover for an intravenous catheter.

Background technique

Inserting a central venous catheter through a peripheral vein is a deep venous catheter technology that is introduced from a peripheral vein and ends in a central vein. It is suitable for long-term intravenous infusion, tumor chemotherapy, parenteral nutrition, and infusion for elderly patients. The application of the central venous catheter avoids the direct contact between the chemotherapy drugs and the arm veins, and the blood flow in the central vein is fast, which can quickly dilute the chemotherapy drugs and prevent the drugs from stimulating the blood vessels. Because of its advantages of simple puncture, safe operation and high puncture success rate, it is more and more widely used in clinical practice. At present, the main vein of the upper arm is generally selected for catheter placement, and it is properly and safely fixed with a transparent film. In order to ensure that the catheter will not be rubbed off by the sleeve and cause unplanned extubation, a mesh sleeve is used clinically to protect the catheter and the positive pressure joint to isolate it from the sleeve. On the one hand, this structure is extremely inconvenient for nurses to observe clinically and evaluate and use the catheter. The mesh sleeve needs to be removed each time to evaluate the use of the catheter. Problems such as prolapse will affect the treatment effect.

Utility model content

The purpose of this utility model is to provide a venous catheter protective cover, which is provided with a cover made of transparent material in the center of the elastic band, which can be covered directly above the puncture site of the venous catheter on the upper arm, thereby facilitating protection and observation of the venous catheter and puncture site.

In order to achieve the above object, the utility model adopts the following technical solutions, including:

an elastic band for wrapping around the patient's upper arm;

A cover body, which is arranged at the center of the elastic band, is used to cover the upper arm venous catheter puncture site directly above, thereby protecting the venous catheter and the puncture site; and

A silicone pad, which is arranged on the outer periphery of the lower end surface of the cover body, is used to reduce the pressure of the cover body on the skin;

Wherein, the cover body is made of a transparent material, and the two ends of the elastic band are respectively provided with a matching Velcro round surface and a Velcro bristle surface.

Preferably, it also includes:

Connector fixing strips, the two ends of which are fixed on the inner end wall of the cover body, and are used to fix the intravenous catheter connector in the unused state on the cover body;

Wherein, the joint fixing strip is made of elastic material.

Preferably, a gap for passing through the intravenous catheter connector is provided at the lower edge of the cover body and the elastic band.

Preferably, the thickness of the silicone pad gradually decreases from the inner edge to the outer edge so as to fit the skin.

Preferably, a plurality of ventilation holes are evenly distributed on the elastic band.

Preferably, a water-absorbing cotton layer is provided on the inner end surface of the elastic band.

The beneficial effect of the utility model is that: a cover body is arranged in the center of the elastic belt, which can be covered directly above the puncture site of the upper arm venous catheter, thereby facilitating protection and observation of the venous catheter and the puncture site.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or other elements or combinations thereof.

As shown in Figure 1-3, a kind of realization form of the present utility model, in order to realize above-mentioned purpose, the present utility model adopts following technical scheme, comprises:

The elastic belt 110 is in the shape of a strip and is used to be wrapped around the patient's upper arm. As a preference, the two ends of the elastic band 110 are respectively provided with a matching Velcro round surface 141 and a Velcro bristle surface 142 .

The cover body 120 is a rectangular parallelepiped shell structure made of transparent material. The cover body 120 is arranged at the center of the elastic band 110, and is used to cover the puncture site of the upper arm venous catheter, thereby protecting the venous catheter and the puncture site. As a preference, the cover body 120 is made of PVC material.

The silicone pad 130 is arranged on the outer periphery of the lower end surface of the cover body 120 for reducing the pressure of the cover body 120 on the skin. As a further preference, the thickness of the silicone pad 130 gradually decreases from the inner edge to the outer edge, so as to fit the skin.

During use, the cover body 120 is facing the puncture site of the upper arm venous catheter, and then the venous catheter connector is stored in the cover body 120, and then the elastic band 110 is wrapped around the arm.

In another embodiment, it also includes: a connector fixing strip 150, the two ends of which are fixed on the inner end wall of the cover body 120, and are used to fix the IV catheter connector in the unused state on the cover body 120; Wherein, the joint fixing strip 150 is made of elastic material.
