DETAILED DESCRIPTION

[0020] To make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Identical parts are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0021] like Figure 1 and Figure 5 As shown, the box body assembly 1 has a sealing sticker 2 bonded to the front end of the box body assembly 1, and a pressing assembly 10 is installed at the rear end of the box body assembly 1. The pressing assembly 10 includes a receiving groove 1001, a third spring 1002, a pressing plate 1003 and a positioning rod 1004. The third spring 1002 is installed inside the receiving groove 1001, the rear end of the third spring 1002 is connected to the pressing plate 1003, and the upper and lower sides of the pressing plate 1003 are connected to the positioning rods 1004.

[0022] When working, the device can be directly attached to the abdomen. At this time, the pressing plate 1003 will rely on the elastic structure formed by the third spring 1002, the positioning rod 1004 and the receiving groove 1001 to press the part of the dialysis tube 7 again, thereby stabilizing the dialysis tube 7. In this way, when connecting the external short tube body 503, it will not pull the connection between the dialysis tube 7 and the human body, so that medical personnel can boldly and confidently perform the connection work, and can also speed up the connection.

[0023] like Figure 2As shown, the box assembly 1 includes a first half box 101, a hinge 102, a second half box 103 and an adhesive strip 104, and the left side of the first half box 101 is connected to the second half box 103 through the hinge 102, and the back of the first half box 101 is adhered with an adhesive strip 104;

[0024] The film on the surface of the adhesive strip 104 is peeled off, and then the first half box 101 and the second half box 103 are pressed to the abdomen, so that the adhesive strip 104 adheres to the body, and the installation of the device is completed.

[0025] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, a collection component 4 is provided inside the first half box 101, a liquid outlet component 3 is provided inside the second half box 103, and a short tube placement handle component 5 is provided between the first half box 101 and the second half box 103, a cleaning component 6 is provided above the short tube placement handle component 5, and a dialysis tube 7 is provided inside the cleaning component 6, and switch components 8 are provided on the left and right sides of the dialysis tube 7.

[0026] like Figure 1 As shown, the liquid outlet assembly 3 includes a liquid storage chamber 301, a liquid outlet 302, a liquid pusher plate 303 and a first spring 304. The liquid outlet 302 is opened on the right side of the liquid storage chamber 301, and the liquid pusher plate 303 is installed inside the liquid storage chamber 301. The lower end of the liquid pusher plate 303 is connected to the first spring 304.

[0027] The blocking block 801 moves downward to expose the liquid outlet 302 . At this time, the first spring 304 pushes the liquid pushing plate 303 upward, thereby squeezing the liquid inside the liquid storage chamber 301 out of the liquid outlet 302 , thereby cleaning the dialysis tube 7 .

[0028] like Figure 1 As shown, the collecting assembly 4 includes a collecting chamber 401 and a collecting port 402, and the collecting port 402 is opened on the left side of the collecting chamber 401;

[0029] The liquid flows back into the collection chamber 401 through the collection port 402 for collection, thus preventing the liquid from leaking out.

[0030] like Figure 1 As shown, the short tube placement assembly 5 includes a placement cavity 501, a fixing block 502 and an external short tube body 503, and the fixing block 502 is installed at the upper end of the placement cavity 501, and the external short tube body 503 is embedded inside the fixing block 502;

[0031] The fixing block 502 fixes the external short tube body 503 and does not affect the rotation of the external short tube body 503 .

[0032] like Figure 1As shown, the cleaning assembly 6 includes a cleaning chamber 601 and a diaphragm 602 , and the diaphragm 602 is installed below the cleaning chamber 601 .

[0033] like Figure 4 As shown, the switch assembly 8 includes a blocking block 801, a rubber block 802, a second spring 803, a locking block 804, and a guide telescopic rod 805. The rubber block 802 is connected to the side of the blocking block 801 close to the dialysis tube 7. The second spring 803 is installed inside the blocking block 801, and the locking block 804 is connected to the side of the second spring 803 away from the dialysis tube 7. The lower end of the blocking block 801 is connected to the guide telescopic rod 805.

[0034] The dialysis tube 7 pushes the rubber block 802 downward, causing the blocking block 801 to descend along the guide telescopic rod 805 until the locking block 804 is aligned with the corresponding locking hole. At this time, the second spring 803 pops out the locking block 804, thereby locking the blocking block 801. The downward movement of the blocking block 801 will expose the liquid outlet 302.

[0035] like Figure 5 As shown, a traction assembly 9 is installed below the internal threaded sleeve of the external short tube body 503, and the traction assembly 9 includes a connecting belt 901, a traction rope 902 and a traction ring 903. The traction rope 902 is wrapped around the outside of the connecting belt 901, and one end of the traction rope 902 is connected to the traction ring 903.

[0036] During use, the dialysis tube 7 is first bent upward, and then the film on the surface of the adhesive strip 104 is peeled off. Then, the first half box 101 and the second half box 103 are pressed against the abdomen, so that the adhesive strip 104 adheres to the body. When adhering, the position of the dialysis tube 7 should be adjusted to the pressing plate 1003. After the adhering is completed, the dialysis tube 7 can be pressed by the elastic structure formed by the pressing plate 1003 through the third spring 1002 and the positioning rod 1004 and the receiving groove 1001, thereby achieving extracorporeal fixation of the dialysis tube 7. In this way, medical staff will not be hesitant when moving the head of the dialysis tube 7.

[0037] Then the medical staff or individual can operate and insert the dialysis tube 7 into the cleaning chamber 601. At this time, the dialysis tube 7 is pressed downward, so that the dialysis tube 7 pushes the rubber block 802 downward, thereby causing the blocking block 801 to descend along the guide telescopic rod 805 until it descends to the point where the locking block 804 is aligned with the corresponding locking hole. At this time, the second spring 803 will pop out the locking block 804, thereby locking the blocking block 801. The downward movement of the blocking block 801 will expose the liquid outlet 302. At this time, the first spring 304 will push the liquid pusher plate 303 upward, thereby squeezing the liquid inside the liquid storage chamber 301 out of the liquid outlet 302, thereby cleaning the dialysis tube 7. The liquid here can be physiological saline or the like.

[0038] The liquid is squeezed out from the liquid outlet 302 to clean the dialysis tube 7. The cleaned liquid will flow back to the collection chamber 401 through the collection port 402 for collection, to prevent the liquid from leaking out and causing water to be everywhere on the equipment, affecting its use.

[0039] When the cleaning is completed, the dialysis tube 7 is pressed downwards, and the dialysis tube 7 pushes the diaphragm 602 open, so that the external thread at the lower end of the dialysis tube 7 is connected with the internal thread on the external short tube body 503. Then the user pulls the traction ring 903 to pull the traction rope 902, so that the traction rope 902 drives the connecting belt 901 to rotate, and the connecting belt 901 drives the external short tube body 503 to rotate, so that the external short tube body 503 and the dialysis tube 7 are connected together through the thread.

[0040] When the dialysis tube 7 and the external short tube body 503 are connected, the user only needs to pull the traction ring 903 downwards, and the traction rope 902 will move on the seam between the first half box 101 and the second half box 103, so that the traction rope 902 can cut the lower sealing patch 2. At this time, the lower end parts of the first half box 101 and the second half box 103 can be opened to remove the pipe part of the external short tube body 503. The lower connection between the first half box 101 and the second half box 103 is located below the adhesive strip 104. There is a small opening, and the external short tube body 503 can be passed through the small opening and then connected to the dialysis equipment for use.

[0041] When dialysis is completed, it is only necessary to pull the rope 902 to cut the upper sealing patch 2. At this time, the box body assembly 1 can be completely opened by relying on the rotating structure formed between the first half box 101 and the second half box 103 through the hinge 102, so that the external short tube body 503 and the dialysis tube 7 can be completely taken out. At this time, the box body assembly 1 can be removed from the human body, and then the external short tube body 503 and the dialysis tube 7 can be disassembled. The user can discard the used external short tube body 503 through the hand-held traction ring 903.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
