Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable three-way pipe connector. Background Technology

[0002] An adjustable three-way connector for connecting a nasogastric tube and a gastric tube is a medical device used to connect the two tubes and allow healthcare professionals to precisely control the flow and direction of fluids. This connector typically has a simple, compact design, including a central inlet and two outlets, one for connecting the nasogastric tube and the other for connecting the gastric tube.

[0003] However, existing adjustable tee fittings have the following disadvantages:

[0004] (1) Medical personnel cannot accurately control the rotation angle of the ball valve core, resulting in poor control effect of the three-way shut-off valve;

[0005] (2) The connection between the tee and the pipeline is not stable and may fall off if accidentally touched, and the sealing is not good.

[0006] Therefore, this utility model provides an adjustable tee connector. Utility Model Content

This solves the problems mentioned in the background art, such as the difficulty for medical personnel to accurately control the rotation angle of the ball valve core, resulting in poor control effect of the three-way shut-off valve, poor connection stability between the three-way pipe and the pipeline, the possibility of detachment due to accidental contact, and poor sealing.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tee pipe connector, comprising a tee pipe body, an mounting rod fixedly mounted on one side of the tee pipe body, a rotating plate rotatably connected to the inner wall of the mounting rod, a rotating rod fixedly mounted on the inner wall of the rotating plate, a snap-fit ​​spring fixedly mounted on the inner wall of the rotating rod, a connecting pipe sequentially threaded to one side of the tee pipe body, and a tightening tube fixedly threaded to the surface of the connecting pipe.

[0011] Optionally, a locking ring is provided on the inner wall of the tightening tube, and an expansion sleeve is fixedly installed at one end of the connecting tube. The cooperation between the expansion sleeve and the locking ring increases the stability of the pipeline and the connecting tube.

[0012] Optionally, one end of the snap-fit ​​spring is movably connected to a snap-fit ​​block, and the inner wall of the mounting rod is sequentially provided with snap-fit ​​grooves that are adapted to the snap-fit ​​block.

[0013] Optionally, a ball valve is fixedly installed at one end of the rotating rod, and a through hole is opened at one end of the ball valve. A handle is fixedly installed at the other end of the rotating rod. Rotating the handle can drive the ball valve to rotate, thereby adjusting the flow direction.

[0014] Optionally, a connecting pipe is fixedly installed at the other end of the connecting pipe. There are three connecting pipes, which can be connected to the pipeline.

[0015] Optionally, a first sealing gasket is fixedly installed at the other end of the connecting pipe, and a second sealing gasket is fixedly installed on the inner wall of the mounting rod. The first and second sealing gaskets can increase the sealing performance of the tee pipe.

[0016] (III) Beneficial Effects

[0017] This utility model provides an adjustable tee connector, which has the following advantages:

[0018] 1. This adjustable three-way pipe connector, through the setting of a rotating plate, rotating rod, snap-fit ​​spring and snap-fit ​​block, serves to rotate the rotating rod by turning the handle when the flow direction needs to be adjusted during use. During the rotation, the snap-fit ​​block compresses the snap-fit ​​spring, and after the rotation is completed, the snap-fit ​​spring and snap-fit ​​block cooperate to limit and fix the rotating rod, which makes it convenient for medical personnel to accurately control the rotation angle of the ball valve core.

[0019] 2. This adjustable tee connector, with its connecting pipe, tightening pipe, locking ring, and expansion sleeve, serves to allow the pipe to be connected to be inserted into the connecting pipe during use. Then, rotating the tightening pipe moves it on the connecting pipe, causing the expansion sleeve to press the pipe together. The locking ring also reinforces the stability of the pipe and the connecting pipe, preventing the pipe from falling off. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable tee pipe connector, including a tee pipe body 1, an mounting rod 2 fixedly installed on one side of the tee pipe body 1, a rotating plate 3 rotatably connected to the inner wall of the mounting rod 2, a rotating rod 4 fixedly installed on the inner wall of the rotating plate 3, and a snap-fit ​​spring 5 fixedly installed on the inner wall of the rotating rod 4. Through the arrangement of the rotating plate 3, rotating rod 4, snap-fit ​​spring 5, and snap-fit ​​block 10, when the flow direction needs to be adjusted during use, the handle 12 is rotated to drive the rotating rod 4 to rotate. During the rotation, the snap-fit ​​block 10 compresses the snap-fit ​​spring 5, and after rotating 90 degrees, the snap-fit ​​spring 5 and the snap-fit ​​block... 10 cooperates to limit and fix the rotating rod 4, which facilitates medical staff to accurately control the rotation angle of the ball valve core. A connecting pipe 6 is sequentially threaded to one side of the three-way pipe body 1. A tightening pipe 7 is fixedly threaded to the surface of the connecting pipe 6. Through the setting of the connecting pipe 6, tightening pipe 7, locking ring 8 and expansion sleeve 9, the pipeline to be connected is inserted into the connecting pipe 13 during use. Then, the tightening pipe 7 is rotated to move on the connecting pipe 6, and the expansion sleeve 9 is driven to press the pipeline. The locking ring 8 can strengthen the stability of the pipeline and the connecting pipe 13 and prevent the pipeline from falling off.

[0027] The inner wall of the tightening tube 7 is provided with a locking ring 8, and one end of the connecting tube 6 is fixedly installed with an expansion sleeve 9. The expansion sleeve 9 works in conjunction with the locking ring 8 to clamp the pipeline.

[0028] One end of the snap-fit ​​spring 5 is movably connected to the snap-fit ​​block 10. The snap-fit ​​block 10 is designed to work with the snap-fit ​​spring 5 to limit and fix the rotating rod 4. The inner wall of the mounting rod 2 is provided with slots that are adapted to the snap-fit ​​block 10.

[0029] A ball valve 11 is fixedly installed at one end of the rotating rod 4. A through hole is opened at one end of the ball valve 11. A handle 12 is fixedly installed at the other end of the rotating rod 4. The handle 12 is used to drive the ball valve 11 to rotate, thereby adjusting the flow direction.

[0030] The other end of the connecting pipe 6 is fixedly installed with a connecting pipe 13. The connecting pipe 13 serves to connect the pipeline. There are three connecting pipes 13.

[0031] The other end of the connecting pipe 6 is fixedly installed with a first sealing gasket 14, and the inner wall of the mounting rod 2 is fixedly installed with a second sealing gasket 15. The setting of the first sealing gasket 14 and the second sealing gasket 15 increases the sealing performance of the tee pipe.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: First, if it is necessary to adjust the flow direction during use, turn the handle 12 to drive the rotating rod 4 to rotate. During the rotation, the locking block 10 compresses the locking spring 5. After rotating 90 degrees, the locking spring 5 cooperates with the locking block 10 to limit and fix the rotating rod 4, so that medical staff can accurately control the rotation angle of the ball valve 11.

[0034] The second step: During use, insert the pipe to be connected into the connecting pipe 13, then rotate the tightening pipe 7 to move it on the connecting pipe 6, and drive the expansion sleeve 9 to press the pipe. The locking ring 8 can strengthen the stability of the pipe and the connecting pipe 13 and prevent the pipe from falling off.
