[0021] In order to make the purpose and the advantages of the utility model more clearly and clearly, the utility model is specifically explained below in combination with examples.It should be understood that the following text is only used to describe one or several specific implementation modes of the utility model, and does not strictly limit the protection range of the specific request of the utility model.

[0022] As Figure 1As shown, a PICC protective sleeve includes two shells 2, a PVC waterproof film 1 fixedly connected between the two shells 2, and a plurality of circular plates 3, the interiors of the plurality of circular plates 3 are each provided with a circular through hole, the circular through holes of the plurality of circular plates 3 are different in diameter, the interiors of the plurality of circular through holes are each fixedly connected with an air bag 4, the upper side of the air bag 4 is fixedly connected with an inflation port 5, the air bag 4 inputs and outputs a first filling medium through the inflation port 5, and any one of the circular plates 3 is detachably mounted in the interior of the shell 2. When used by a user, the user can replace the circular plates 3 according to the girth of the user's upper limbs, assemble the circular plates 3 that are suitable for the girth of the user's upper limbs on the shell 2, then insert the upper limb of the user with the PICC into the interiors of the circular through holes of the two circular plates 3, so that the two circular plates 3 are respectively located at the upper end and the lower end of the PICC, and the PVC waterproof film 1 is located outside the indwelling area of the user's upper limb with the PICC. At this time, the PVC waterproof film 1 can reduce the contact between the external water flow and the indwelling area, and reduce the infection phenomenon caused by the contact between the user and the water flow when the user washes. At the same time, when used, the first filling medium is filled into the interior of the air bag 4 through the inflation port 5, so that the air bag 4 expands to abut against the user's upper limb, and fills the gap between the user's upper limb and the circular plate 3, thereby improving the waterproof sealing performance of the PICC.

[0023] Referring to Figures 1-2 , the peripheral side of the circular plate 3 is provided with external threads, the inner side of the shell 2 is provided with internal threads, and the circular plate 3 is threadedly connected in the interior of the shell 2. The mutual engagement of the threads makes the connection close and stable, has good waterproof sealing performance, can withstand large tensile force and shear force, is not easy to loosen, and is convenient for the user to replace the circular plate 3 when used, is simple and convenient, and is easy to operate.

[0024] Referring to Figures 2-3 , a groove is formed at the middle position of the peripheral side of the circular plate 3, the interior of the groove is fixedly connected with an air bag 7, the air bag 7 is provided with an inflation port 6 extending to the upper side of the circular plate 3, and the air bag 7 inputs and outputs a second filling medium through the inflation port 6. When the circular plate 3 is threadedly connected to the interior of the shell 2, the second filling medium can be input into the interior of the air bag 7 through the inflation port 6. At this time, the air bag 7 will expand due to the input of the second filling medium, so that the air bag 7 closely adheres to the inner wall of the shell 2, thereby further increasing the sealing performance between the shell 2 and the circular plate 3.

[0025] The first filling medium is a gas or a liquid, and is preferably water with a temperature range of 0-10°C. After the user has just finished PICC catheterization, the temperature of the water contacts the user's skin through the air bag 2 at this time, and the water with a temperature range of 0-10°C can relieve the slight swelling and discomfort during puncture.

[0026] As Figure 2 and Figures 4-5As shown, a plurality of annular array supports 8 are fixedly connected between the two housings 2 and inside the PVC waterproof film 1, and in use, the supports 8 are inside the PVC waterproof film 1, which can support the PVC waterproof film 1 and reduce the pushing displacement of the PICC tube when the PVC waterproof film 1 contacts the PICC tube.

[0027] The housing 2 is made of silica gel, which can reduce the scratch on the user's limbs in use.

[0028] The working principle of the utility model is as follows:

[0029] In use, the circular plate 3 can be replaced according to the circumference of the user's upper limb, and the circular plate 3 suitable for the user is assembled on the housing 2, and then the second filling medium is input into the air bag 7 through the inflation port 6 to make the air bag 7 expand to fit the inner wall of the housing 2, further increasing the sealing between the housing 2 and the circular plate 3.

[0030] The upper limb of the user with the PICC is inserted into the circular through hole of the two circular plates 3, so that the two circular plates 3 are located at the upper end and the lower end of the PICC respectively, and the PVC waterproof film 1 is located outside the PICC placement area of the user's upper limb, at this time, the PVC waterproof film 1 can reduce the contact between the external water flow and the placement area, reduce the infection caused by the contact between the user and the water flow during washing, and at the same time, the first filling medium is filled into the air bag 1 through the inflation port 1 in use, so that the air bag 1 expands to abut against the user's upper limb, filling the gap between the user's upper limb and the circular plate 3, thereby improving the waterproof sealing of the PICC.

[0031] In summary, the PVC waterproof film 1, the air bag 1 and the air bag 7 can form a protective sleeve with good waterproof performance outside the PICC placement area of the user's upper limb, reduce the infection caused by the contact between the user and the water flow during washing, and through the replacement of the circular plate 3, it can be applied to different upper limb dimensions.

[0032] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principle of the utility model, some improvements and refinements can be made, which should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the art, unless otherwise specified and limited.
