Description

Technical Field

[0001] The invention belongs to the technical field of chemotherapy drug delivery equipment, and in particular relates to an anti-extravasation chemotherapy drug delivery device for oncology. Background Art

[0002] In oncology, extravasation of chemotherapy drugs (i.e., leakage of drugs into the tissues surrounding blood vessels) may cause serious complications (such as tissue necrosis, ulcers, nerve damage, etc.). Therefore, prevention of extravasation is a core part of chemotherapy care. When preventing extravasation, chemotherapy is often administered to patients through an infusion pump.

[0003] For example, the utility model with application number: CN201921458861.9 discloses an anti-extravasation chemotherapy drug delivery device for oncology, comprising a main liquid bottle and a secondary liquid bottle, wherein the lower parts of the main liquid bottle and the secondary liquid bottle are both interspersed with fixed rods, and the lower ends of the main liquid bottle and the secondary liquid bottle are jointly movably installed with a dual-control liquid delivery device, the lower end of the dual-control liquid delivery device is fixedly installed with a drug delivery hose, the left part of the drug delivery hose is movably installed with an arm fixing device, the right end of the drug delivery hose is movably connected to a drug delivery needle, and a regulator is interspersed with the middle part of the drug delivery hose. The anti-extravasation chemotherapy drug delivery device for oncology described in the utility model can pre-dose chemotherapy patients and observe whether indirect extravasation will occur by arranging a dual-control liquid delivery device on the entire drug delivery device, and arrange an arm fixing device and a drug delivery needle to prevent extravasation from occurring at the connection between the needle and the venous blood vessel. The entire drug delivery device has a simple structure and is easy to use, and can effectively prevent and stop extravasation during chemotherapy administration.

[0027] A chemotherapy drug delivery device for preventing extravasation in oncology, such as Figure 1-7 As shown, it includes an infusion tube 3, one end of the infusion tube 3 is connected to a connecting needle 1, and the other end of the infusion tube 3 is connected to an injection needle 8; the infusion tube 3 is also provided with a Murphy's dropper 4, and the infusion tube 3 is also provided with a regulator 5 arranged between the Murphy's dropper 4 and the injection needle 8; the connecting needle 1 is provided with an exhaust hole 2, and the infusion tube 3 is provided with a filter 6; the infusion tube 3 is also detachably connected to a syringe, and the detachable connection method of the syringe and the infusion tube 3 is the existing technology and will not be repeated here. The syringe is connected to the injection needle 8, and the injection needle 8 is provided with a needle handle 7.

[0028] When the present invention is in use, the infusion bottle is connected through the connecting needle 1, and the injection needle 8 is connected to the patient's vein; the infusion operation is performed for the patient through the cooperation of the infusion tube 3, the Murphy dropper 4, the regulator 5, the exhaust hole 2, etc., and the infusion rate is regulated by the regulator 5 so that the infusion rate corresponds to the patient's condition, thereby improving the patient's recovery effect.

[0029] Furthermore, the regulator 5 includes an adjusting frame 9, which is provided with a guide structure corresponding to the infusion tube 3, and the adjusting frame 9 is provided with an adjusting structure for squeezing and adjusting the infusion tube 3; the adjusting structure includes an eccentric wheel 31 rotatably connected to the adjusting frame 9, and the eccentric wheel 31 is rotatably connected to an adjusting wheel 13 for squeezing and adjusting the infusion tube 3, and the adjusting wheel 13 is provided with a connecting assembly that cooperates with the eccentric wheel 31, and a baffle 17 that cooperates with the adjusting wheel 13 is fixedly connected to the adjusting frame 9; an adjusting motor 12 is fixedly connected to the adjusting frame 9, and the output end of the adjusting motor 12 is fixedly connected to the eccentric wheel 31.

[0030] When the regulator 5 is in use, the regulating wheel 13 rotates along the eccentric wheel 31, so that the axis of the regulating wheel 13 is aligned with the rotation center of the eccentric wheel 31 or is eccentrically arranged; when the axis of the regulating wheel 13 is aligned with the rotation center of the eccentric wheel 31, as shown in FIG. Figure 2 As shown, at this time, under the action of the connecting assembly, when the eccentric wheel 31 rotates, it drives the adjusting wheel 13 to make a circular motion along the rotation center of the eccentric wheel 31 and cooperates with the baffle 17 to squeeze the infusion tube 3; the adjusting wheel 13 can continuously and evenly squeeze the infusion tube 3, so that the air in the infusion tube 3 can be squeezed into the Murphy-type dropper 4 through the infusion tube 3, so as to prevent the air in the infusion tube 3 from flowing into the patient's body with the liquid, causing discomfort to the patient, thereby improving the functionality of the present application.

[0031] When the axis of the adjusting wheel 13 is eccentric to the rotation center of the eccentric wheel 31, under the action of the connecting component, the eccentric wheel 31 drives the adjusting wheel 13 to rotate eccentrically along the rotation center of the eccentric wheel 31 and cooperate with the baffle 17 to squeeze the infusion tube 3. As the eccentric wheel 31 rotates, the adjusting wheel 13 changes the squeezing amplitude of the infusion tube 3, thereby adjusting the infusion rate of the infusion tube 3; in addition, the rotation of the eccentric wheel 31 is controlled by the adjusting motor 12. The present application can be used in conjunction with the corresponding drip detection equipment, so that the adjusting motor 12 can adjust the eccentric wheel 31 in real time to improve the adjustment effect of the present application on the infusion rate.

[0032] Furthermore, the guide structure includes a vertical guide assembly connected to the adjustment frame 9, and a horizontal guide assembly is slidably connected to the adjustment frame 9 and cooperates with the vertical guide assembly; the infusion tube 3 is constrained and guided by the cooperation of the vertical guide assembly and the horizontal guide assembly to improve the stability of the connection between the infusion tube 3 and the adjustment wheel 13.

[0033] Furthermore, the vertical guide assembly includes a pair of guide wheels 18 rotatably connected to the adjustment frame 9 and respectively arranged on both sides of the infusion tube 3. A lifting rod 26 slidably connected to the adjustment frame 9 is provided on the side of the baffle 17 away from the guide wheel 18. As the lifting rod 26 slides along the adjustment frame 9, the horizontal adjustment assembly slides synchronously along the adjustment frame 9; the lifting frame 14 is fixedly connected to the lifting rod 26, and the lifting frame 14 is rotatably connected to a pair of lifting wheels 15 arranged on both sides of the infusion tube 3.

[0034] When the vertical guide assembly is in use, the pair of guide wheels 18 cooperates with the pair of lifting wheels 15 to clamp and guide the infusion tube 3, so as to improve the stability of the contact between the infusion tube 3 and the adjusting wheel 13; in addition, the lifting wheel 15 is adjusted by the lifting rod 26 and the lifting frame 14 to change the distance between the lifting wheel 15 and the guide wheel 18, thereby changing the length of the infusion tube 3 between the lifting wheel 15 and the guide wheel 18, thereby improving the stability of the contact between the infusion tube 3 and the adjusting wheel 13.

[0035] Furthermore, the adjusting frame 9 is rotatably connected to a pair of opening and closing rods 19, and the pair of opening and closing rods 19 are rotatably connected to opening and closing wheels 20. The pair of opening and closing wheels 20 are arranged on the side of the guide wheel 18 away from the lifting wheel 15, and slide along the adjusting frame 9 synchronously with the lifting rod 26 as the opening and closing rod 19 rotates along the adjusting frame 9; a sliding rod 28 is fixed to the adjusting frame 9, and a slider 22 is slidably connected to the sliding rod 28, and a first top spring 23 that cooperates with the slider 22 is sleeved on the sliding rod 28; a pair of connecting rods 21 are rotatably connected to the slider 22, and the other ends of the pair of connecting rods 21 are respectively rotatably connected to the middle parts of the pair of opening and closing rods 19; one of the opening and closing rods 19 is connected to a synchronization rod 24, and the synchronization rod 24 is rotatably connected to an output rod 25, and the other end of the output rod 25 is rotatably connected to the lifting frame 14.

[0036] The opening and closing wheel 20 provided on the opening and closing rod 19 cooperates with the lifting wheel 15 and the guide wheel 18 to guide the infusion tube 3 to improve the stability of the infusion tube 3. In addition, when the regulating wheel 13 squeezes the infusion tube 3, the bubbles in the infusion tube 3 flow into the Murphy-type dropper 4. When the regulating wheel 13 rotates and squeezes the infusion tube 3, the regulating wheel 13 drives the entire application to move along the infusion tube 3. When the regulating wheel 13 moves close to the Murphy-type dropper 4, the Murphy-type dropper 4 cooperates with the opening and closing wheel 20. Down, the opening and closing rod 19 is rotated along the adjusting frame 9, so that the opening and closing wheel 20 is opened and clamped on the Murphy-type dropper 4; when the opening and closing rod 19 is rotated, the opening and closing rod 19 drives the slider 22 to slide along the slide rod 28 through the connecting rod 21 and squeezes the first top spring 23; at the same time, the opening and closing rod 19 drives the synchronization rod 24 to rotate, and the synchronization rod 24 drives the lifting frame 14 to slide through the lifting rod 26 adjustment frame 9 through the output rod 25, thereby increasing the distance between the guide wheel 18 and the lifting wheel 15 to improve the stability of the present application.

[0037] Furthermore, the lateral guide assembly includes a guide block 11 fixed to the adjustment frame 9, and a limit frame 10 is slidably connected to the guide block 11, and both ends of the limit frame 10 are rotatably connected to limit wheels 16 for limiting the infusion tube 3; an L-shaped rod 29 is rotatably connected to the adjustment frame 9, one end of the L-shaped rod 29 is rotatably connected to the active rod 27, and the other end of the active rod 27 is rotatably connected to the lifting rod 26; the other end of the L-shaped rod 29 is rotatably connected to the driven rod 30, and the other end of the driven rod 30 is rotatably connected to the limit frame 10.

[0038] When the transverse guide assembly is in use, the infusion tube 3 is limited by a pair of limiting wheels 16 cooperating with the lifting wheel 15 and the guide wheel 18 to prevent the infusion tube 3 from separating from the adjusting wheel 13, thereby improving the stability of the infusion tube 3; in addition, when the lifting rod 26 slides along the adjusting frame 9, the lifting rod 26 drives the L-shaped rod 29 to rotate through the active rod 27, and the L-shaped rod 29 drives the limiting frame 10 to slide along the guide block 11 through the driven rod 30, so that the limiting frame 10 and the lifting rod 26 move synchronously. In addition, the lifting rod 26 moves synchronously with the opening and closing rod 19, that is, if it is necessary to separate or install the present application from the infusion tube 3, the opening and closing rod 19 can be rotated, thereby causing the limiting frame 10 to drive the limiting wheel 16 away from the adjusting frame 9, so that the present application is easy to install on the infusion tube 3; in addition, under the action of the first top spring 23, the limiting wheel 16 and the opening and closing wheel 20 are both in a state of clamping the infusion tube 3, thereby improving the stability of the infusion tube 3.

[0039] Furthermore, if Figure 6 and Figure 7 As shown, the connecting assembly includes plug-in grooves uniformly distributed along the circumference of the eccentric wheel 31, a plug-in block 34 that cooperates with the plug-in grooves is slidably connected to the adjusting wheel 13, and a push block 32 is fixedly connected to the plug-in block 34; the plug-in block 34 is also fixedly connected to a guide rod 35 that is slidably connected to the adjusting wheel 13, and a second top spring 33 that cooperates with the plug-in block 34 is sleeved on the guide rod 35.

[0040] When the adjusting wheel 13 rotates along the eccentric wheel 31, the plug-in block 34 is driven to slide along the adjusting wheel 13 by the pushing block 32, so that the plug-in block 34 is separated from the plug-in slot; the adjusting wheel 13 is rotated along the eccentric wheel 31 for adjustment. After the adjustment is completed, the pushing block 32 is released, so that the plug-in block 34 is installed and matched with the plug-in slot under the action of the second top spring 33, thereby realizing the connection between the adjusting wheel 13 and the eccentric wheel 31. When the eccentric wheel 31 rotates, the adjusting wheel 13 can be driven to rotate through the cooperation between the plug-in block 34 and the plug-in slot, thereby improving the convenience of this application.

[0041] The working process of the present invention is:

[0042] When the present invention is in use, the infusion bottle is connected through the connecting needle 1, and the injection needle 8 is connected to the patient's vein; the infusion operation is performed for the patient through the cooperation of the infusion tube 3, the Murphy dropper 4, the regulator 5, the exhaust hole 2, etc., and the infusion rate is regulated by the regulator 5 so that the infusion rate corresponds to the patient's condition, thereby improving the patient's recovery effect.

[0043] When the regulator 5 is in use, the guide wheel 18, the lifting wheel 15, the opening and closing wheel 20 cooperate with the limiting wheel 16 to limit and guide the infusion tube 3, so as to improve the contact stability of the infusion tube 3 and the regulating wheel 13; when the axis of the regulating wheel 13 is eccentric to the rotation center of the eccentric wheel 31, under the action of the connecting component, the eccentric wheel 31 rotates, and the regulating wheel 13 can be driven to rotate by the cooperation of the plug block 34 and the plug slot; the regulating wheel 13 rotates eccentrically along the rotation center of the eccentric wheel 31 and cooperates with the baffle 17 to squeeze the infusion tube 3. As the eccentric wheel 31 rotates, the regulating wheel 13 changes the squeezing amplitude of the infusion tube 3, thereby adjusting the infusion rate of the infusion tube 3; in addition, the rotation of the eccentric wheel 31 is controlled by the regulating motor 12. The present application can be used in conjunction with the corresponding drip detection equipment, so that the regulating motor 12 can adjust the eccentric wheel 31 in real time to improve the regulating effect of the present application on the infusion rate.

[0044] When the infusion tube 3 needs to be vented, the axis of the regulating wheel 13 is aligned with the rotation center of the eccentric wheel 31, as shown in FIG. Figure 2 As shown, at this time, under the action of the connecting component, when the eccentric wheel 31 rotates, it drives the adjusting wheel 13 to make a circular motion along the rotation center of the eccentric wheel 31 and cooperates with the baffle 17 to squeeze the infusion tube 3; the adjusting wheel 13 can continuously and evenly squeeze the infusion tube 3, and drive the entire application to move along the infusion tube 3, so that the air in the infusion tube 3 can be squeezed into the Murphy-type dropper 4 through the infusion tube 3, so as to avoid the air in the infusion tube 3 from flowing into the patient's body with the liquid, causing discomfort to the patient, thereby improving the functionality of the application.

[0045] When the adjusting wheel 13 moves along the infusion tube 3 to a position close to the Murphy's dropper 4, the opening and closing rod 19 rotates along the adjusting frame 9 under the cooperation of the Murphy's dropper 4 and the opening and closing wheel 20, so that the opening and closing wheel 20 opens and clamps on the Murphy's dropper 4; at the same time, the opening and closing rod 19 drives the synchronization rod 24 to rotate, and the synchronization rod 24 drives the lifting frame 14 to slide through the lifting rod 26 adjusting frame 9 through the output rod 25, thereby increasing the distance between the guide wheel 18 and the lifting wheel 15, so as to improve the stability of the present application.
