Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, the utility model provides a PICC thrombolytic nursing device, comprising:

[0027] Infusion tubes 1, which are provided in two groups and are vertically distributed, are an indispensable tool in modern medicine. They are medical devices used to inject liquid medicines, vaccines, or extract body fluids such as blood and urine. Infusion tubes 1 are usually made of transparent plastic and can be filled with liquid medicine. Scales are marked on the surface for accurate measurement.

[0028] The three-way tube 2 is arranged at the vertical foot of the two sets of infusion tubes 1, and both ends of the three-way tube 2 are sleeved on one end of the infusion tube 1. The three-way tube 2 is an important medical device, widely used in various clinical applications, mainly used for fluid diversion, channel switching and connection, and can be used for intravenous infusion. It can connect multiple intravenous infusion lines to facilitate the simultaneous delivery of medicines or nutrient solutions;

[0029] The fixing component is installed on the outside of the two groups of infusion cylinders 1. The fixing component includes a fixing ring 3, which is sleeved on the outside of the infusion cylinder 1, and there are two groups of fixing rings 3. A connecting rod 4 is fixedly installed between the two groups of fixing rings 3. The inner wall diameter of the fixing ring 3 is the same as the outer wall diameter of the infusion cylinder 1.

[0030] A rubber pad is pressed onto the inner wall of the fixing ring 3, and a rubber sleeve is provided on the outer surface of the connecting rod 4. Both the rubber pad and the rubber sleeve are made of natural rubber, generally synthetic rubber. Synthetic rubber is a rubber material manufactured by chemical synthesis and has properties similar to natural rubber. Synthetic rubber can be formulated according to different needs to obtain specific physical and chemical properties, and has the characteristics of sealing, anti-slip, wear resistance and elasticity. This design utilizes the anti-slip properties of rubber, increases the friction between the fixing ring 3 and the infusion cylinder 1, and is conducive to making the fixing ring 3 more tightly and stably set. The rubber sleeve on the surface of the connecting rod 4 increases the friction between the connecting rod 4 and the hand, which is conducive to more stable grip.

[0031] Example 2

[0032] like Figure 3 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment further proposes: a drive component, the drive component is installed at the rear end of the infusion cylinder 1, the drive component includes a shell 5, the shell 5 is arranged at the rear end of the infusion cylinder 1, and a handpiece 6 is fixedly installed at the bottom of the shell 5, and two groups of control buttons 7 are provided on one side of the handpiece 6, an upper mounting plate 10 is fixedly installed on the top of one side of the shell 5, and a card slot 11 is provided at the bottom of the upper mounting plate 10, a lower mounting plate 8 is fixedly installed on the bottom of one side of the shell 5, and a slide 9 is provided on the top of the lower mounting plate 8, a limiting groove 14 is fixedly installed on the top of one end of the infusion cylinder 1, a slider 13 is fixedly installed on the bottom of one end of the infusion cylinder 1, and the slider 13 is embedded in the slide 9 and is slidably connected to the slide 9, and the limiting groove 14 is inserted in the card slot 11 and is slidably connected to the card slot 11, the top of the upper mounting plate 10 is penetrated by a fixing bolt 12 through a thread, and the bottom of the fixing bolt 12 is inserted into the limit groove 14, one end of the housing 5 is installed with a mounting seat 15, and the side of the mounting seat 15 close to the infusion cylinder 1 is fixedly installed with an electric telescopic rod 16, and the output end of the electric telescopic rod 16 is installed with a piston 17, and the electric telescopic rod 16 is installed inside the housing 5. The electric telescopic rod 16 is a device with adjustable length, which is commonly used in various applications, such as photography, lighting, construction, cleaning and other industries. The electric telescopic rod 16 can achieve fast and convenient extension and retraction through an electric mechanism to adapt to different usage scenarios. The design can control the electric telescopic rod 16 by pressing the control button 7 and cooperating with the circuit connection;

[0033] A fixing groove 18 is provided inside the piston 17. The two sides of the output end of the electric telescopic rod 16 are set as flat surfaces and inserted into the fixing groove 18.

Screws 20 are passed through the top and bottom of the limit ring 19, and the tail of the screw 20 is inserted into the output end of the electric telescopic rod 16 through a thread.

[0034] The piston 17 fits tightly against the inner wall of the infusion tube 1. The piston 17 is a slidable part inside the infusion tube 1 and is usually made of rubber or plastic. Liquid is sucked or injected by manually pushing it. The tight fit between the piston 17 and the inner wall of the infusion tube 1 helps to improve air tightness.

[0035] Working principle: first connect one end of the three-way tube 2 to the PICC, then pass the infusion tube 1 filled with medicine through the fixing ring 3 and insert it into the end opposite to the PICC on the three-way tube 2, and then pass another set of infusion tubes 1 through the other set of fixing rings 3 and insert it into the remaining port of the three-way tube 2. When in use, you can hold the connecting rod 4 with one hand and the handpiece 6 with the other hand. By pressing the control button 7, the output end of the electric telescopic rod 16 can be driven to move forward or backward. The output end of the electric telescopic rod 16 can drive the piston 17 to move inside the infusion tube 1. When use is finished and it needs to be disassembled and replaced, the infusion tube 1 can be pulled out from the three-way tube 2, and then the fixing bolt 12 can be unscrewed, and then the infusion tube 1 can be pulled out, so that the limit groove 14 slides in the card groove 11, and the slider 13 slides in the slide groove 9, and then the screw 20 can be unscrewed to remove the piston 17. The above is the entire working principle of the utility model.
