Description

Technical Field

[0001] This utility model relates to the field of medical tool technology, specifically to a retractable waterproof protective cover. Background Technology

[0002] Protective sleeves are clinical equipment used to protect indwelling needle tubes. For example, the patent with publication number "CN118750735A" is entitled "A PICC Catheter Fixator". The fixation of this patent is an oblique connection, which fixes the PICC catheter connector while retaining a certain degree of biceps brachii muscle mobility, making it easy for the patient to move their arm slightly.

[0003] However, the device still has some drawbacks. For example, if the catheter connector is worn and then protected by the protective sleeve, the indwelling catheter can be protected to a certain extent, but the patient cannot take a shower because some water will flow into the protective sleeve and easily flow back into the catheter, which can breed bacteria.

[0018] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0019] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Example 1:

[0023] Please combine Figure 1 and Figure 3 Referring to the above, a retractable waterproof protective sleeve includes an inner sleeve 10, which includes a fixed end 101 and a retractable end 102. An elastic band 20 is provided at the end of the fixed end 101. Adjusting the elastic band 20 can adjust the tightness of the fixed end 101 on the arm. A storage bag 30 is provided outside the fixed end 101. An outer sleeve 40 is provided inside the storage bag 30. One end of the outer sleeve 40 is fixed inside the storage bag 30, and the other end can extend outward to wrap the inner sleeve 10 and form a sealed area with the patient's arm.

[0024] Furthermore, the outer cover 40 is rolled up in the storage bag 30, and the length of the outer cover 40 is longer than that of the inner cover 10. An elastic band 20 is also provided at the other end of the outer cover 40.

[0025] Understandably, when the inner sleeve 10 is worn on the patient's arm, the fit between the patient and the inner sleeve 10 can be adjusted by adjusting the elastic band 20. This maximizes the patient's comfort when not showering, improving overall comfort and fit. When showering is required, the outer sleeve 40 can be unrolled by opening the storage bag 30. Before this, to ensure overall waterproofness, the elastic band 20 can be tightened until the fixed end 101 is in close contact with the skin. Then, the outer sleeve 40 can be unrolled so that it completely covers the inside, and the elastic band 20 at the other end of the outer sleeve 40 can be tied tightly.

[0026] Furthermore, the outer jacket 40 is made of polyethylene.

[0027] Understandably, the polyethylene outer sheath 40 allows for clear observation of the inner sheath 10 during showering. If water ingress is detected, the internal condition can be observed immediately and addressed promptly, which helps protect the patient's catheter from moisture.

[0028] Furthermore, the scaling end 102 is divided into two lobes, with the distance between the two lobes of the scaling end 102 increasing sequentially. The surface of the scaling end 102 is provided with a plurality of fixing posts 103, and also includes an elastic rope 50, which can be wound around the two lobes of the scaling end 102.

[0029] It is understandable that one end of the scaling end 102 is connected to the fixed end 101, and the other end extends outside the box. During the extension process, the distance between the two scaling ends 102 gradually increases. Therefore, when wearing this design, the fixed end 101 is fitted on the patient's arm, and the scaling end 102 is an adjustable part. The patient can adjust the elastic cord 50 by wrapping it around the fixed post 103 according to their own situation. The more times it is wrapped, the closer the two scaling ends 102 are to each other, and the more closely it fits the patient's arm.

[0030] Furthermore, the fixing post 103 is T-shaped.

[0031] Furthermore, the surface of the scaling end 102 is provided with a through hole 104.

[0032] Furthermore, the inner sleeve 10 is provided with a color-changing coating 60, which changes color when exposed to water. It can be understood that the color-changing coating 60 is provided at the top and bottom of the inner sleeve 10 to facilitate observation of whether moisture has entered.

[0033] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
