【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1a and Fig. 1b, a trocar that prevents falling off includes a trocar body, a trocar body is provided with a tip 11, an anti-falling device 12 to prevent the trocar from falling off, and a trocar stopper 13; the trocar body is internally provided with The liquid medicine flow channel 18 and the air channel 19, the tip 11 is provided with a liquid suction hole and an exhaust hole respectively communicating with the liquid medicine flow channel 18 and the air channel 19; the air channel 19 is connected with the exhaust pipe arranged at the tail of the trocar body Body 15 is connected.

As shown in Figure 2, the anti-falling device 12 is arranged in the operating cavity in the trocar body, including a spring sheet, a button 14 and a spring 16, and a first convex body 20 and a second convex body 21 are arranged on the same side of the spring sheet; A convex body 20 is inverted V-shaped, M-shaped, inverted U-shaped or arc-shaped. The spring 16 presses the leaf spring, the first convex body 20 of the spring leaf passes through the trocar outer wall 17 of the tip 11 , and the second convex body 21 passes through the tail of the trocar body and is connected with the button 14 . There are two spring sheets, which are symmetrically arranged on both sides of the trocar body. The spring 16 is arranged at the junction between the first convex body 20 and the second convex body 21 . The position where the first convex body 20 passes through the tip 11 is set between the piercer blocking plate 13 and the liquid suction hole. An anti-leakage silicone sheet is provided at the contact between the first convex body 20 and the tip 11 to prevent the liquid medicine from entering into the operation chamber of the trocar body, causing unnecessary waste.

As shown in Figure 3, an infusion set that prevents falling off includes a piercer 1, and an upper hose 3, a drip funnel 5, a lower hose 6, a liquid medicine filter 8 and an infusion needle that are sequentially connected to the piercer 1 9. The exhaust pipe connector 15 is connected to the exhaust pipe 2, the upper hose 3 is provided with a side pipe, and the latex cap 4 is arranged on the side pipe; the lower hose 6 is provided with a flow regulating valve 7; The bottle stopper of the infusion bag or the infusion bottle, the bottle stopper is between the fall-off prevention device 12 and the piercer block 13 .

The working principle of the utility model is: when the puncturer 1 pierces the cork of the infusion bag or infusion bottle, under the squeeze of the cork, the first convex body 20 of the spring plate presses down on the spring, and the spring stores energy at the same time. The whole leaf spring is retracted into the operating cavity in the trocar body, the trocar 1 can pierce the bottle stopper, and the tip 11 is inserted into the infusion bag or the infusion bottle. Since the spring releases energy after storing energy, the first convex body 20 pops out the tip 11 of the piercer 1, and the first convex body 20 can hold the bottle stopper to prevent the piercer 1 from falling due to natural or common external force. Play the purpose of preventing falling off. When pulling out, press the button 14, the spring leaf and the spring retract, and it is easy to pull out the trocar. The liquid medicine enters from the liquid medicine flow channel 18 and flows into the piercer 1, while the air enters the inside of the infusion bag or the infusion bottle from the air passage 19 to ensure sufficient pressure balance. Other functions are the same as those of common infusion sets.
