[0041] Figure 1 A structural schematic diagram of an embodiment of the present invention is shown, specifically showing the structure of this embodiment. This embodiment relates to a new type of medical conversion device and a method of use. When a hemodialysis patient is put on the machine or the hemodialysis machine needs to be disinfected, there is no need to plug and unplug the quick connector. The liquid supply and disinfection modes can be switched by rotating the handle. The device is small in size and easy to replace. The overall port is highly integrated. When replacement is required, the hospital equipment department can complete it by itself, which greatly reduces the time cost of replacement.

[0042] In the traditional fluid supply mode, the operation of the hemodialysis machine and the central fluid supply system is as follows: Figure 5 As shown, when the traditional central liquid supply system is in liquid supply mode, the male quick connector of the liquid supply system is connected to the female connector of the liquid suction end of the hemodialysis machine to form a passage, while the liquid return end of the hemodialysis machine and the female quick connector of the central liquid supply system are disconnected, so it is in liquid supply mode at this time;

[0043] In traditional disinfection mode, hemodialysis machines such as Figure 6 As shown, and the central liquid supply system is as Figure 7 As shown, in the disinfection mode, the male and female heads of the quick connectors of the hemodialysis machine are connected to form a closed loop for pipeline disinfection; in the disinfection mode, the male and female heads of the quick connectors of the central liquid supply system are connected to form a closed loop for pipeline disinfection.

[0044] The steps used in this method are as follows:

[0045] A first flow tube, a second flow tube and a third flow tube are arranged in the adapter, wherein one end of the first flow tube is connected to the regulating mechanism and finally connected to the central liquid supply system;

[0046] The other end of the first flow tube is connected to the second flow tube and the third flow tube respectively, and the second flow tube and the third flow tube are connected to the hemodialysis machine;

[0047] The central fluid supply system can provide medical fluid through the first circulation tube, the regulating mechanism can control the opening and closing of the pipeline, and the hemodialysis machine can perform internal circulation through the circulation of the second circulation tube and the third circulation tube to realize fluid supply to the hemodialysis machine; when the control regulating mechanism makes the central fluid supply system unable to supply fluid to the hemodialysis machine through the pipeline, the hemodialysis machine can perform internal disinfection.

[0048] This embodiment provides a novel medical conversion device and a method of use, such as Figure 1-4 and Figure 9-10 As shown, it includes an adjustment mechanism and an adapter, wherein the adjustment mechanism includes a circulation chamber 1, an adjustment shaft 2, a connecting pipe 3, a rotating handle 4, a connecting rod 5 and a closing plate 6, wherein the circulation chamber 1 is a closed cylindrical sealed cabin for circulation conversion of disinfectant or medical supply liquid. In this embodiment, three circulation pipes 3 are arranged on the outside of the circulation chamber 1, and the connecting pipe can be inserted into each circulation pipe 3 for connection between the central liquid supply system arranged outside and the hemodialysis machine, as shown in FIG. Fig. 9 and Fig.10 As shown, one of the flow pipes 3 is connected to one end of the first connecting pipe 9 provided in the adapter, and the other end is connected to the second connecting pipe 10 and the third connecting pipe 11 respectively, a first flow port 12 and a second flow port 13 are provided at the top inclined surface of the first connecting pipe 9, the second flow pipe 10 is connected to the first flow port 12, the third flow pipe 11 is connected to the second flow port 13, and the flow inside the adapter that is connected and fixed forms a U-shaped flow pipe;

[0049] The first flow tube 9 of the adapter is connected to the central liquid supply system, and the second flow tube 10 and the third flow tube 11 are respectively connected to the hemodialysis machine. When the regulating mechanism is turned on, the medical supply liquid flows into the second communication tube 10 and the third communication tube 11 to the hemodialysis machine through the first communication tube 9;

[0050] When the regulating mechanism is closed, the medical supply fluid cannot flow in from the first circulation tube 9, and the hemodialysis machine can form an internal circulation through the second circulation tube 10 and the third circulation tube 11 to complete the disinfection of the hemodialysis machine.

The adjusting shaft 2 is vertically arranged inside the circulation bin 1, and is placed horizontally with the bin body of the circulation bin 1 and one end is perpendicular to the bottom of the circulation bin 1. The adjusting shaft 2 is threadedly connected to the circulation bin 1, and a rotating handle 4 is arranged on the other end of the adjusting shaft 2. The rotating handle 4 is fixedly connected to the adjusting shaft 2. Turning the rotating handle 4 will not rotate and remove the rotating handle 4 from the adjusting shaft 2. The relative height of the adjusting shaft 2 in the circulation bin 1 can be adjusted by rotating the rotating handle 4, so as to realize the lifting and lowering adjustment of the adjusting shaft 2; a connecting rod 5 is fixed on the adjusting shaft 2, and one end of the connecting rod 5 is embedded and fixed on the adjusting shaft 2, and a closing plate 6 is installed and fixed on the other end. The plate body of the closing plate 6 is bent, which is consistent with the curvature of the inner wall of the circulation bin 1. The rotation and lifting of the adjusting shaft 2 can drive the lifting and rotating of the connecting rod 5, so that the closing plate 6 moves and lifts along the inner wall of the circulation bin 1, so that the closing plate 6 can move to the circulation pipe 3 to close the pipe mouth, so as to realize the blocking of the supply liquid or disinfectant, and the rotation and rotation The handle 4 drives the adjusting shaft 2 to rotate, which can drive the closing plate 6 to move away from the pipe mouth of the circulation pipe 3 to complete the supply of the supply liquid or the circulation of the disinfectant; at the same time, a sealing shell 7 is installed on the outside of the adjusting mechanism, so that the device of this embodiment has a beautiful appearance and strong tightness, which can prevent the leakage of the circulating liquid for a second time. In some feasible embodiments, sensors and alarms are arranged inside the sealing shell 7 and on the outside of the circulation bin 1, which can monitor the leakage of the circulation bin 1 in real time and prompt through the sound or light of the alarm to improve the safety of the device of this embodiment; a blocking mark 8 is arranged at the sealing shell 7 corresponding to the rotating handle 4. Since the connecting rod 5 is fixed on the adjusting shaft 2, the rotation of the adjusting shaft 2 drives the moving position of the connecting rod 5 to be fixed, so the moving direction of the closing plate 6 to move away or block the circulation pipe 3 is fixed, so the blocking mark 8 can be set according to the rotation range of the adjusting shaft 2, and the rotating handle 4 can rotate the adjusting shaft 2 according to the blocking mark 8 to realize the control of the circulation or blocking of the circulation pipe 3.

[0052] In some feasible embodiments, the regulating mechanism can be set as a three-way ball valve, the two pairs of quick connectors in the prior art are eliminated, and the pipelines are connected and fixed using a hose, and the disinfection or liquid supply mode is switched by rotating the three-way ball valve of the device of this embodiment; Figure 8 As shown in the figure, A and D are normally open; when the ball valve rotates to the liquid supply mode, port B is disconnected, and ports A, C, and D are all passages; when the ball valve rotates to the disinfection mode, ports A and D and the central liquid supply system form a closed-loop passage, and ports B and C and the hemodialysis machine form a closed-loop passage. In this embodiment, the disinfection and flushing of the workpiece can be effectively ensured during disinfection and cleaning, and in the liquid supply mode, there will be no lack of liquid in the pipeline.

[0053] The advantages and positive effects of the present invention are: due to the adoption of the above technical solution, when the hemodialysis patient is put on the machine or the hemodialysis machine needs to be disinfected, there is no need to plug and unplug the quick connector, and the liquid supply and disinfection modes can be switched by rotating the ball valve; the device is small, simple, generous, easy to replace, and highly integrated as a whole.
