Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a post-operative waterproof device. Background Art

[0002] Waterproof isolation sleeves are suitable for situations where the hands and feet cannot touch water after fractures or injuries. Most of the existing waterproof isolation sleeves for hands and feet on the market are made of PVC, silicone and polyester TPU. The waterproof isolation sleeves for hands and feet made of polyester TPU have poor softness and poor air permeability and moisture permeability. PVC has poor elasticity and poor high and low temperature resistance. Silicone is not air-permeable. In addition, the waterproof isolation sleeves for hands and feet made of the above materials must be equipped with a shrinkable fixing belt at the wearing opening, which can play a shrinking and fixing role after wearing, making the hands and feet uncomfortable.

[0003] The existing patent is a polyether TPU medical waterproof isolation sleeve for hands and feet. The patent authorization number is CN208692354U. By pulling the hand wearing opening and the foot wearing opening to both sides, the hands and feet are easy to wear the waterproof isolation sleeve. After wearing, since the material of the waterproof isolation sleeve, polyether TPU, has better shrinkage than other materials, it can automatically shrink close to the arm, calf or thigh, and there is no need to set a shrinkable fixing belt. The waterproof isolation sleeve is waterproof and can block external water from entering the sleeve to prevent water and bacteria in the water from invading the wound and preventing wound infection. It can be used in situations where the hands and feet cannot touch water after fractures or injuries. The frosted surface of the hand waterproof isolation sleeve can play a non-slip role and does not stick to the skin.

[0004] However, the waterproof isolation sleeve in patent authorization number CN208692354U does not have a protective function before use, resulting in the risk of the waterproof isolation sleeve being scratched before use, thereby affecting its waterproof effect. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a post-operative waterproof device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An internal thread screwed to the external thread is formed on the top inner wall of the second protective shell, and a second boss in an annular structure is fixedly connected to the inner wall of the second protective shell below the internal thread;

[0010] A storage cavity is provided between the first boss and the second boss, and the flexible PVC waterproof isolation cover is located inside the storage cavity;

[0011] The top end of the first protective shell and the bottom end of the second protective shell are both connected with a waterproof elastic sleeve.

[0012] Preferably, two ends of the flexible PVC waterproof isolation cover are respectively connected to the first boss and the second boss through sealant.

[0013] Preferably, the joints between the waterproof elastic sleeve and the first protective shell and the second protective shell are coated with sealant.

[0014] Preferably, an elastic sealing rubber ring is installed on the inner side of the waterproof elastic sleeve.

[0015] Preferably, a non-slip silicone ring is installed on one side of the elastic sealing rubber ring, and the surface of the non-slip silicone ring is provided with non-slip patterns.

[0016] Preferably, the elastic sealing rubber ring and the anti-slip silicone ring are both connected to the waterproof elastic sleeve by hot melting.

[0017] The utility model provides a postoperative waterproof device, which has the following beneficial effects:

[0018] 1. The second protective shell is manually held and rotated relative to the first protective shell until the external thread set at the connecting head is disengaged from the internal thread, and then the flexible PVC waterproof isolation cover is unfolded, and the first protective shell, the flexible PVC waterproof isolation cover and the second protective shell are successively set on the patient's arm or leg, and the device is positioned by tightening with a waterproof elastic sleeve. The flexible PVC waterproof isolation cover is stored in a storage cavity provided between the first boss and the second boss before use, which plays a good protective role for the flexible PVC waterproof isolation cover to avoid scratching before use, thereby improving the waterproof effect during use.

[0019] 2. The elastic sealing rubber ring can fit closely with the skin to fill the gap between the skin and the waterproof elastic sleeve, thereby improving the waterproof effect. The anti-slip silicone ring is used to increase the friction between the skin and the device, which can effectively prevent the device from slipping off after being worn.
