[0027] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] The following is combined Figures 1-5 This utility model will be described in detail.

[0029] Example:

[0030] A clog-resistant filter infusion set includes a puncture needle 1 for puncturing a medicine bottle, a drip chamber 11 connected to the puncture needle 1 via a pipe, a filter 9 connected to the drip chamber 11 via a pipe, and an infusion needle 10 connected to the filter 9 via a pipe. The filter 9 includes a circular outer shell 901 with pipes connecting both sides. A hollow rotating element 902 is rotatably sealed in the circular outer shell 901. A drain port 908 and two inlets 905 are provided on the side wall of the hollow rotating element 902. A filter element 907 is provided in each of the inlets 905.

[0031] like Figure 1 and Figure 3 As shown, one of the inlets 905 is aligned with the input pipe of the medicine. The medicine enters the circular outer shell 901 from the input pipe. The medicine passes through the filter element 907 in the inlet 905 to filter impurities. The filtered medicine enters the hollow rotating part 902 and enters the output pipe from the outlet 908. The arc length of the outlet 908 is greater than the arc length of the two inlets 905, so that after the positions of the two inlets 905 are adjusted, the outlet 908 is always connected to the output pipe. When the inlet 905 is blocked, the hollow rotating part 902 is rotated to align the other inlet 905 with the input pipe, thus realizing the anti-clogging function of the filter 9. The operation is simple and convenient.

[0032] A limiting ring 904 is connected to the circular outer shell 901 to restrict the hollow rotating member 902 within the circular outer shell 901. For example... Figure 2 and 4 As shown, the limiting ring 904 cooperates with the circular outer shell 901 to restrict the hollow rotating part 902 inside the circular outer shell 901, so that the hollow rotating part 902 can only rotate inside the circular outer shell 901 and cannot move out of the circular outer shell 901.

[0033] A toggle block 903 is provided on the upper end face of the hollow rotating component 902. The toggle block 903 facilitates the operator to rotate the hollow rotating component 902, thereby switching the position of the liquid inlet 905.

[0034] like Figure 2 As shown, a notch is provided on the limiting ring 904, and the actuating block 903 extends into the notch and abuts against the limiting ring 904. When the actuating block 903 abuts against one side of the limiting ring 904, one of the liquid inlets 905 is aligned with the liquid input pipe. When the actuating block 903 abuts against the other side of the limiting ring 904, the other liquid inlet 905 is aligned with the liquid input pipe. This allows the operator to directly adjust the position in one step, avoiding the situation where the liquid inlet 905 is not aligned with the liquid input pipe, which would cause the liquid to flow poorly.

[0035] Three first sealing rings 906 are provided on the side wall of the hollow rotating component 902. The three first sealing rings 906 are respectively disposed around the two liquid inlets 905 and the liquid outlet 908. The first sealing rings 906 are respectively fitted around the two liquid inlets 905 and the liquid outlet 908, so that the liquid inlets 905 and the liquid outlet 908 are sealed with the inner wall of the circular outer shell 901. This ensures that the liquid medicine can only enter the hollow rotating component 902 from one of the liquid inlets 905 and also prevents unfiltered liquid medicine from directly entering the liquid medicine output pipe through the gap between the hollow rotating component 902 and the circular outer shell 901.

[0036] like Figure 4 As shown, a second sealing ring 909 is fitted onto the hollow rotating component 902, and the second sealing ring 909 is located above the first sealing ring 906. The second sealing ring 909 seals the upper gap of the hollow rotating component 902, preventing impurities from the outside of the filter 9 from entering the interior of the filter 9 and affecting the safety of the medicine.

[0037] A fluid guide bottle 5 is connected between the puncture needle 1 and the drip chamber 11. A first flow rate regulator 3 is installed on the pipe connecting the fluid guide bottle 5 and the puncture needle 1. A water stop clamp 6 is installed on the pipe connecting the fluid guide bottle 5 and the drip chamber 11. A scale line 4 is installed on the fluid guide bottle 5.

[0038] Currently, the only available solvent bottles are 50 ml, 100 ml, 250 ml, and 500 ml. However, with the increasing use of precision medicine and individualized medication regimens, clinical practice often requires solvents ranging from 300 ml to 490 ml. The existing sizes cannot meet clinical needs, necessitating the use of syringes to draw the required solvents. However, the largest syringe size is only 60 ml. To draw solvents larger than 60 ml, the rubber stopper must be repeatedly punctured, which can easily leave rubber microparticles in the solution, causing contamination. During repeated large-dose aspiration, improper operation can easily cause the hand to touch the syringe plunger, contaminating the solution and harming the patient. Furthermore, the time required for repeated large-dose aspiration can easily lead to hand fatigue and cause tenosynovitis. Therefore, a liquid guide bottle 5 is provided, which is equipped with an exhaust pipe (not shown in the figure) to assist in discharging the liquid. The liquid guide bottle 5 is connected to the solvent bottle through the puncture needle 1, and the scale line 4 on the liquid guide bottle 5 indicates the amount of liquid. In use, the stop clamp 6 is closed and the first flow rate regulator 3 is opened. When the required amount of liquid is about to be reached, the flow rate of the liquid is reduced by the first flow rate regulator 3 and then closed to accurately control the amount of liquid. After that, the stop clamp 6 is opened to release the liquid, avoiding the operation of using a syringe to draw up the liquid.

[0039] A heater 8 is installed on the pipe between the drip chamber 11 and the filter 9. The heater 8 can heat the pipe containing the medicine, reducing the irritation when the medicine enters the body and increasing the patient's comfort.

[0040] like Figure 5 As shown, the heater 8 includes two hinged clamps 801. Heating elements (not shown) are installed inside the clamps 801, and a power cord 804 is connected to the heating elements. One side of each clamp 801 has a serpentine groove 802 for engaging the infusion tubing. Magnets 803 attract each other on both clamps 801. After the tubing is engaged in the serpentine groove 802, the two clamps 801 are flipped closed and secured by the magnets 803, allowing the heater 8 to be mounted and fixed on the tubing to heat the medication. This facilitates disassembly and reuse of the heater 8 after use. The clamps 801 also contain a temperature sensor and a control module (not shown) for controlling the power supply to the heating elements. The temperature sensor detects the temperature of the heating elements. When the temperature rises to a set value, the control module disconnects the power to the heating elements; when the temperature drops to the set value, the control module reconnects the power, achieving a constant temperature heating effect.

[0041] A second flow rate regulator 7 is installed on the pipe between the dripper 11 and the filter 9. The second flow rate regulator 7 can control the delivery speed of the medicine solution so that the delivery speed meets different usage requirements.

[0042] Infusion set usage process:

[0043] like Figure 1 As shown, the puncture needle 1 is used to puncture the medicine bottle (solvent bottle) to guide the medicine out. The puncture needle 1 is equipped with an exhaust pipe 2 to facilitate the smooth flow of the medicine in the medicine bottle. The medicine enters the infusion bottle 5 through the pipe for quantitative dispensing. After the medicine is dispensed in a quantitative manner, the first flow rate regulator 3 is closed and the stop clamp 6 is opened. The medicine enters the drip chamber 11 for venting and displaying the drip rate. After being heated by the heater 8, it enters the filter 9 for impurity filtration and finally enters the blood vessel through the infusion needle 10.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
