[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The present application embodiment discloses a protective cover for a puncture needle or a sharp metal tube. Figure 1 The protective cover for the puncture needle or sharp metal tube includes a pair of silicone positioning plates 1, an abutment plate 2 for abutting the medical device is arranged between the two silicone positioning plates 1, and a clamping piece for clamping the medical device is arranged between the two silicone positioning plates 1. That is, the sharp medical device is inserted into the clamping piece, and its end abuts against the abutment plate 2 to complete the positioning and fixation, thereby completing the protection and fixation of the medical device. In order to ensure that the two silicone positioning plates 1 are away from the abutment plate 2, a connecting plate 3 for mutual connection is arranged at one end, so that a frame is formed between the silicone positioning plates 1, the abutment plate 2 and the connecting plate 3, thereby ensuring the structural stability of the entire protective cover.

[0028] The clamping member includes an upper elastic compression strip 4 and a lower elastic compression strip 5 arranged between two silicone positioning plates 1, and a gap is set between the upper elastic compression strip 4 and the lower elastic compression strip 5, so that the medical device is inserted into the upper elastic compression strip and the lower elastic compression strip 5, and the upper elastic compression strip and the lower elastic compression strip 5 are squeezed to deform and clamp the medical device, thereby completing the function of fixing and protecting the medical device. In order to ensure that the medical device can accurately abut on the abutment plate 2, a hemispherical positioning groove 21 is provided on the abutment plate 2, so that when the medical device is inserted into the positioning groove 21, it will be gradually corrected, thereby ensuring that the sharp needle of the medical device can be positioned in the positioning groove 21 without protruding, thereby ensuring the protection of the medical device.

[0029] A plurality of upper elastic compression strips 4 and lower elastic compression strips 5 are arranged at equal intervals, and the plurality of upper elastic compression strips and lower elastic compression strips are arranged in an up-and-down staggered manner along the length direction of the silicone positioning plate 1. That is, the upper elastic compression strips 4 and lower elastic compression strips 5 are arranged in a row to ensure the stability of the fixation of the medical device and the comprehensiveness of the protection. And because of the staggered arrangement, the sterilizing agent is ensured to penetrate normally, thereby ensuring the sterilization effect.

[0030] Because multiple upper elastic compression strips 4 and lower elastic compression strips 5 are provided, which may cause greater resistance when the subsequent medical device is inserted, the thickness of the upper elastic compression strips 4 and the lower elastic compression strips 5 gradually decreases from the middle to the two ends and then increases to ensure that the middle part has a certain thickness to protect the product. At the same time, the thickness on both sides of the edge is reduced to facilitate deformation and clamping of the product.

[0031] In order to further improve the convenience of inserting medical devices, a tapered guide groove 31 is provided on the connecting plate 3, which gradually shrinks toward the abutment plate 2. A tapered groove 6 which gradually shrinks toward the abutment plate 2 is provided on the adjacent surfaces of the upper elastic compression strip 4 and the lower elastic compression strip 5 on the side away from the abutment plate 2, for guiding the insertion of the medical device, thereby facilitating the insertion of the sharp end of the medical device into the protective cover.

[0032] The two silicone positioning plates 1 are provided with a plurality of anti-skid protrusions 7 on the opposite sides thereof to facilitate holding.

[0033] The implementation principle of the protective cover for a puncture needle or a sharp metal tube in the embodiment of the present application is as follows: a sharp medical device is inserted into the clamping member, and its end abuts against the abutment plate 2 to complete positioning and fixation, thereby completing the protection and fixation of the medical device. The sharp end of the medical device abuts against the abutment plate 2, and the upper elastic clamping member and the lower elastic clamping member on the back of the peripheral side of the medical device are clamped and fixed, thereby reducing the occurrence of the protective cover falling off, thereby ensuring the protection effect. The upper elastic clamping strip 4 and the lower elastic clamping strip 5 are both arranged in a row to ensure the stability of the fixation of the medical device and the comprehensiveness of the protection; and because of the staggered arrangement, the normal penetration of the sterilizing agent is ensured, thereby ensuring the sterilization effect.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
