The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A medical dressing 100 according to an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in fig. 1 and 2, a medical dressing 100 according to an embodiment of the present invention for fixing an intravenous catheter on the skin, the medical dressing 100 includes: an applicator body 10 and a protective sheath 20.

Specifically, the applicator body 10 is detachably connected with the skin, the first end of the intravenous catheter is positioned between the applicator body 10 and the skin, the protective sleeve 20 is arranged on the side, away from the skin, of the applicator body 10, the protective sleeve 20 is provided with a channel, the first end of the channel is provided with a first opening 21, the second end of the channel is provided with a second opening 22, the second end of the intravenous catheter is placed in the channel through the first opening 21, the second opening 22 can be opened or closed, and when the second opening 22 is opened, the second end of the intravenous catheter can pass through the second opening 22.

In other words, the applicator body 10 according to the embodiment of the present invention is mainly composed of the applicator body 10 capable of fixing the first end of the intravenous catheter to the skin, and the protector 20 capable of accommodating the second end of the intravenous catheter. Wherein the applicator body 10 is detachably connected to the skin, for example, the applicator body 10 may be adhesively connected to the skin. It should be noted that the protector 20 is provided on the applicator body 10, and the protector 20 is located on the side away from the skin.

Further, the protective sheath 20 has a channel, a first end of the channel has a first opening 21, a second end of the channel has a second opening 22, and the second opening 22 can be opened or closed. For example, the protective sheath 20 may be made of medical plastic or medical silicone, and is not particularly limited thereto. In addition, a zipper or a snap may be used to open or close the second opening 22, which is not particularly limited herein.

Wherein the second end of the intravenous catheter is capable of extending into the passageway through the first opening 21. When the second opening 22 is closed, the second end of the intravenous catheter can be stored within the passageway, preventing contamination of the second end of the intravenous catheter from external bacteria. When the second opening 22 is opened, the second end of the intravenous catheter may extend out of the second opening 22 and other tubing may be connected to the second end of the intravenous catheter for use.

In the use, medical personnel get into the blood vessel with the first end puncture of venous catheter, and after the puncture, medical personnel can use and apply ointment or plaster body 10 to fix venous catheter's first end and skin. The second end of the intravenous catheter is then advanced into the passageway along the first opening 21 with the second opening 22 in the closed position. When it is desired to connect another fluid line to the second end of the intravenous line, the second opening 22 may be opened to allow connection of another fluid line to the second end of the intravenous line.

Therefore, according to the medical application 100 provided by the embodiment of the utility model, by combining the application body 10 and the protective sleeve 20, not only can the first end of the intravenous catheter be conveniently and fixedly connected with the skin, but also the second end of the intravenous catheter can be placed in the protective sleeve 20, and the second end of the intravenous catheter can be effectively prevented from being polluted by the external environment on the premise of not influencing the use.

According to one embodiment of the utility model, the medical dressing 100 further comprises: and the sealing part 30, wherein the sealing part 30 is arranged at the second opening 22, and the sealing part 30 can open or close the second opening 22. Fig. 2 shows a state in which the sealing portion 30 is opened. Alternatively, the enclosure 30 and the protective sleeve 20 may be made of the same material. The shape of the sealing portion 30 may be the same as the shape of the second opening 22, and is not limited herein. By arranging the packaging part 30, the protective sleeve 20 can have a tighter protection effect, and air in the external environment is prevented from polluting the intravenous catheter.

In some embodiments of the utility model, the enclosure 30 is removably coupled to the protective sleeve 20. For example, the enclosing portion 30 may be adhesively connected to the protecting cover 20, or the enclosing portion 30 may be threadedly connected to the protecting cover 20, which is not described in detail herein. By detachably connecting the enclosure 30 to the protective sheath 20, the enclosure 30 can be replaced with a new enclosure 30 when the enclosure 30 is unable to work properly, thereby preventing the medical applicator 100 from being used.

That is, when it is desired to open the second opening 22, the second opening 22 may be opened by tearing the tear line. The easy-tear line is easy to process and prepare, so that the production cost of the protective sleeve 20 can be reduced. And the operation and the use of medical personnel are convenient, and a large amount of time is saved.

In some embodiments of the present invention, as shown in fig. 1 and 2, the applicator body 10 is provided with an escape groove 11, the escape groove 11 is elongated, a first end of the escape groove 11 extends to the edge of the applicator body 10, and a second end of the escape groove 11 extends toward the direction in which the first opening 21 is located. In other words, the applicator body 10 is provided with an elongated avoidance groove 11, and the avoidance groove 11 is arranged opposite to the first end of the intravenous catheter. And the escape groove 11 can extend from the edge of the applicator body 10 toward the direction of the first opening 21. The specific length of the escape groove 11 is not limited herein. Through set up on applying ointment or plaster body 10 with the first end position of ductus venosus dodge groove 11 relatively, be favorable to fixed inseparabler with ductus venosus and skin, avoid ductus venosus's position to remove at will.

According to one embodiment of the utility model, the width of the escape slot 11 is smaller than the width of the intravenous line. That is, the clearance of the escape groove 11 is smaller than the tube diameter of the intravenous catheter. By designing the width of the avoidance groove 11 to be smaller than the width of the intravenous catheter, the avoidance groove 11 is enabled to better define the position of the intravenous catheter, so that the intravenous catheter is not easy to move in the direction of the tube diameter.

In some embodiments of the utility model, the length of the protective sheath 20 is no less than the length of the catheter hub. Wherein the second end of the venous catheter is a catheter connector. That is, the catheter hub can be placed completely within the protective sheath 20. The length of the protective sheath 20 may be greater than the length of the catheter adapter, and the length of the protective sheath 20 may also be equal to the length of the catheter adapter, which may be selected according to actual needs.
