The existence of — 602 always gives the blocking plate 5 a thrust away from the convex ring 15, so that the blocking plate 5 does not adhere to the convex ring 15 when there is no other external force.

In this embodiment, as shown in Figure 5, a cap body 7 is integrally formed on the inner side of the liquid outlet 4 below, and several liquid guide ports 8 are arranged on the inner end side of the cap body 7, and the liquid can flow from the liquid guide port 8 to the The inside of the cap body 7 flows; the outer wall of the cap body 7 is slidably sleeved with a blocking member 9 for blocking the liquid guide port 8, and the specific blocking member 9 includes a ring 901 set on the cap body 7, and the ring 901 The sides can cover all the liquid guide ports 8 so that the liquid cannot flow from the liquid guide ports 8 into the cap body 7, and at the same time, a radially protruding pressure bearing ring 902 is integrally formed on the outer wall of the ring 901;

In addition, a spring mechanism 2 10 is provided between the pressure bearing ring 902 of the blocking member 9 and the box body 1, and the specific spring mechanism 2 10 includes a telescopic rod 1001 fixedly installed between the box body 1 and the blocking member 9, The spring two 1002 is connected outside the telescopic rod 1001, and the two ends of the spring two 1002 are fixed on the box body 1 and the blocking member 9 respectively. The pressure makes the ring 901 outside the liquid guide port 8, so that the liquid cannot enter the liquid outlet 4 when there is no other external force;

In this embodiment, as shown in FIG. 2 , conduits 11 are fixedly connected to the outer sides of the two liquid outlets 4 , and the two conduits 11 are connected to each other. Specifically: the conduits 11 include chambers 3 and 3 from above, respectively. Tube 1 1101 and tube 2 1102 lead out from the chamber 3 below, and the end of tube 2 1102 connects to tube 1 1101 , and also includes tube 3 1103 .

In this embodiment, as shown in Figures 1 and 2, a drainage mechanism 12 is connected between the second pipe 1102 and the third pipe 1103. The specific drainage mechanism 12 includes a motor 1201 fixedly installed on the outer wall of the box body 1, the motor The output shaft of 1201 is keyed to the gear pump 1202, and the gear pump 1202 is connected to the second pipe 1102 and the third pipe 1103. In order to realize the protection of the motor 1201 and the gear pump 1202, an outer cover is provided on the outside of the motor 1201 and the gear pump 1202 1203, and the outer cover 1203 is installed on the outer wall of the box body 1.

As shown in Figure 2 again, the end of the pipe three 1103 is fixedly connected with a flushing part 13, and the specific flushing part 13 includes a hose 1301 detachably connected to the pipe three 1103, and the end of the hose 1301 is fixedly connected with a flushing Rod 1302, the detachable method can be interference socket or hoop connection.

The utility model provides a drainage flusher for postoperative wounds with a disinfection function. The specific working principle is as follows: the chamber 3 of the disinfectant is pulled by a spring mechanism-6 to block the blocking plate 5, so that the blocking plate 5 is far away from the convex ring 15, Then the disinfectant can flow into the catheter 11 from the liquid outlet 4, and the chamber 3 of the flushing liquid is pulled by the spring mechanism 2 10 to pull the blocking member 9, so that the blocking member 9 is wrapped on the liquid guide port 8, so that the flushing liquid cannot enter Conduit 11; Under the action of the gear pump 1202 of the drainage mechanism 12, negative pressure is generated inside the first tube 1101 and the second tube 1102. Due to the effect of the negative pressure, the disinfectant in the conduit 11 flows to the flushing part 13 to disinfect the wound. Simultaneously, due to the negative pressure, the equilibrium state of the blocking plate 5 is broken, and now the blocking plate 5 is gradually approaching the protruding ring 15 under the effect of the negative pressure until it fits together, and then the liquid outlet 4 is blocked; at this time , the internal negative pressure breaks the balance of the blocking member 9, and the negative pressure plate of the traction blocking member 9 (it is a circular plate with a cross-sectional area smaller than the inner diameter of the cap body 7, is provided with a chute at the cap body 7, and passes through The connecting block of the chute connects the negative pressure plate and the ring 901, and ensures that the negative pressure plate and the ring 901 can move synchronously) to move outwards, and the ring 901 can be dragged to be removed from the liquid guide port 8. At this time A large amount of irrigating liquid enters the catheter 11. After the disinfectant is drawn out, the irrigating liquid is sprayed out immediately, and the disinfection and rinsing are designed as a continuous process, which reduces the time interval and reduces the risk of secondary infection of the wound.
