[0001] The present application relates to the field of indwelling needles, and in particular to a transparent waterproof protective cover for an indwelling needle. Background Art

[0002] Closed catheter infusion is a commonly used nursing technique in clinical care. Some outpatients need to be discharged with an indwelling catheter, which presents numerous inconveniences during home care, including the risk of catheter slippage. Currently, transparent elastic tape is used to help secure the catheter and facilitate observation of the skin condition at the puncture site.

[0003] During the use of the indwelling needle, the indwelling needle structure mainly includes a three-way pipe. One end of the three-way pipe is opened to connect to the steel needle, and the other end is opened for adding medicine. At the same time, the other end is sealed by an isolation plug. In addition, the outer wall of the three-way pipe is connected to an extension tube, which is used for infusion. However, the indwelling needle is fixed to the human arm by the existing transparent tape. Specifically, the transparent tape covers the needle tube and the three-way pipe. At the same time, the medicine addition port at one end of the three-way pipe needs to be exposed on the outside of the transparent tape. Therefore, there is a sealing problem between the transparent tape, the three-way pipe and the human skin. For this reason, we propose a transparent waterproof protective cover for the indwelling needle. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a transparent waterproof protective cover for an indwelling needle, aiming to improve the problem of poor sealing between the transparent tape, the three-way tube and the human skin.

[0019] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0020] See also Figure 1-4The present application provides a transparent waterproof protective cover for an indwelling needle, comprising a transparent cover 10 and a three-way tube 50. A transparent tape 20 is connected to the outer wall of the transparent cover 10, and a through hole 30 is opened on one end side thereof, a sealing ring 40 is installed in the through hole 30, and one end of the three-way tube 50 is connected to a needle tube 60. After the needle tube 60 is inserted into the skin, the transparent cover 10 is placed on the three-way tube 50, and the other end of the three-way tube 50 is passed through the sealing ring 40. Specifically, by setting the transparent cover 10 and opening the through hole 30 on the transparent cover 10, a sealing ring 40 is installed in the through hole 30, and the sealing ring 40 is elastically arranged, so that the drug adding end of the three-way tube 50 can pass through the sealing ring 40, thereby improving the sealing effect between the three-way tube 50 and the transparent cover 10, and the transparent tape 20 is integrally arranged with the transparent cover 10. The transparent tape 20 is adhered to the human skin to achieve the sealing purpose, thereby improving the overall sealing.

[0021] See Figure 1 The transparent cover 10 is elastically set and tilted. When set, the transparent cover 10 is made of plastic. It is also convenient to observe the inside of the transparent cover 10. The tilt degree of the transparent cover 10 is the same as the tilt degree of the three-way pipe 50.

[0022] See Figure 4 A sealing ring 410 is fixedly connected to the side walls at both ends of the sealing ring 40. The two sealing rings 410 are respectively attached to the outer wall and inner wall of the transparent cover 10. In the specific setting, the two sealing rings 410 are respectively attached to the outer wall and inner wall of the transparent cover 10, which can improve the sealing between the sealing ring 40 and the through hole 30. At the same time, the two sealing rings 410 cooperate to fix the sealing ring 40 in the through hole 30.

[0023] See Figure 3 An extension tube 70 is connected to the outer wall of the tee tube 50, and the extension tube 70 extends from the bottom of the transparent tape 20. The inlet end of the extension tube 70 is connected to the existing joint, and is connected to the infusion tube through the existing joint to achieve the purpose of infusion. At the same time, the extension tube 70 extends from the bottom of the transparent tape 20, so that when the transparent tape 20 is attached to the human skin, the extension tube 70 is also sealed on the human skin.

[0024] See Figure 1 The side walls at both ends of the transparent tape 20 are fixedly connected with extended tapes 210 . By connecting the extended tapes 210 at both ends of the transparent tape 20 , the stability of the transparent tape 20 is improved.

[0025] See Figure 3 and 4The three-way pipe 50 includes a main pipe 510, one end of which is connected to a connecting pipe 520, which passes through the sealing ring 40, and the needle tube 60 is connected to the other end of the main pipe 510. The extension pipe 70 is connected to the outer wall of the main pipe 510, and the diameter of the connecting pipe 520 is smaller than the diameter of the main pipe 510. It should be noted that the diameter of the connecting pipe 520 is smaller than the diameter of the main pipe 510, so that one end of the main pipe 510 is against the sealing ring 410 on the inner side of the transparent cover 10, thereby limiting the three-way pipe 50 and avoiding the needle tube 60 from slipping.

[0026] When using this transparent waterproof protective cover for an indwelling needle: after the puncture of the needle tube 60 is completed, the transparent cover 10 is covered on the three-way pipe 50, and then the sealing ring 40 is put on the connecting pipe 520, and at the same time, one end of the main pipe 510 is in contact with the sealing ring 410 inside the transparent cover 10 to limit the three-way pipe 50, and then the transparent tape 20 can be pasted on the human skin, and at the same time, the transparent tape 20 fixes the extension pipe 70 on the human skin, and finally, the extension tape 210 is fixed on the human skin, and the connecting pipe 520 is sealed by the existing isolation plug, and at the same time, the inlet end of the extension pipe 70 is connected to the existing connector, and the connector is connected to the infusion tube to achieve infusion.

[0027] It should be noted that the specific models and specifications of the three-way tube 50 and the needle tube 60 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
