DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment, the embodiment provides a kind of multi-joint postoperative wound flushing infusion device, as shown in Figure 1 Including infusion main pipe 1, one end of infusion main pipe 1 is connected with double-end connector, and double-end connector end is closely inserted with access pipe 2, and the end of access pipe 2 is connected with plug 21, flushing liquid (flushing liquid can be saline, can also be just the liquid of adding anti-inflammatory drug, can play the role of anti-inflammatory, also can play the role of just flushing wound) is filled into filling bag, and is empty and hung on hanger, plug 21 can then be pierced into filling bag to enter filling bag, flushing liquid can flow into infusion main pipe 1 by plug 21.Usually, double-end connector connects two access pipes 2, that is, plug 21 also has two, two plugs 21 can be inserted into two filling bags to meet the demand of flushing liquid required by wound flushing.

[0024] As shown in Figure 1 The other end of infusion main pipe 1 is connected with flushing pipe 11, and the end of flushing pipe 11 is dressing hollow connector one 12, first paste dressing at the wound of patient, and open the insertion hole that can be convenient for dressing hollow connector one 12 to pass on dressing, in this way, closed flushing space of flushing channel can be formed on wound surface.For the case that wound is small, it is not necessary to flush a large amount of flushing liquid to wound in unit time, only need to make flushing liquid in infusion main pipe 1 flow into flushing pipe 11, and then flow out from dressing hollow connector one 12 to reach wound to flush, and then the waste liquid after flushing is extracted through the negative pressure suction pipe passing through dressing, and continuous flushing achieves the purpose of cleaning wound.

[0025] For the case that wound is large, as shown in Figure 1, Figure 2 and Figure 4 As shown, multiple diversion tubes 3 can be detachably installed on the radial sidewall of the end of the infusion main tube 1 near the flushing tube 11. Specifically, such as... Figure 5 As shown, the radial sidewall of the infusion main tube 1 near the irrigation tube 11 has multiple insertion grooves 13. The sidewall of the insertion groove 13 away from the groove opening has a thin wall 15 for penetration. A hollow connector is fixedly connected to the outer wall of one end of the shunt tube 3. The end of the hollow connector has a reducing plug 32. The end of the reducing plug 32 can pierce the thin wall 15 and enter the infusion main tube 1, realizing the fluid circuit connection between the shunt tube 3 and the infusion main tube 1. The other end of the shunt tube 3 is connected to a dressing hollow connector 31. An insertion port is opened on the dressing to facilitate the passage of the dressing hollow connector 12. Multiple shunt tubes 3 and irrigation tubes 11 form a multi-irrigation pipeline to meet the irrigation needs of larger wounds.

[0026] Multiple diversion tubes 3 are selected to form a multi-irrigation pipeline with the irrigation tube 11. This can thoroughly remove wound exudate and pus produced by necrotic tissue, ensuring wound cleanliness. It can also act as artificial skin, effectively sealing the wound and creating a low-oxygen environment within the wound to protect it and prevent external bacterial infection.

[0027] It should be noted that the thickness of the thin wall 15 is 1-1.5 mm. It is preferred to use a 1 mm thick thin wall 15, so as to facilitate the easy penetration of the plug 32 into the infusion tube 1.

[0028] In addition, to prevent the shunt tube 3 from falling off during flushing, multiple guide sleeves 14 are fixed to the radial sidewall inside the main infusion tube 1. One end of the guide sleeve 14 is an enlarged end 142, and the other end is a constricted end 141. The enlarged end 142 is continuously connected to the constricted end. The enlarged end 142 of the guide sleeve 14 is fixedly connected to the thin-walled insert 15. The inner diameter of the constricted end 141 is equal to the outer diameter of the shrink plug 32. At the same time, the end of the shrink plug 32 is a hollow hemispherical structure 33, and the radius of the hollow hemispherical structure 33 is larger than the outer diameter of the shrink plug 32. Holding the hollow connector of the shunt tube 3, insert the hollow hemispherical structure 33 at the end of the shrink plug 32 into the insertion groove 13, and continue to apply force along the groove. Figure 5Continue to push the hollow hemispherical structure 33 in the direction indicated by the arrow Q, and use the hollow hemispherical structure 33 to pierce the thin wall 15, then the hollow hemispherical structure 33 will advance along the enlarged end 142 of the guide sleeve 14, when the hollow hemispherical structure 33 enters the contraction end 141, resistance will be generated, here the guide sleeve 14 is made of medical silica gel, in this way, slightly push the hollow hemispherical structure 33, the hollow hemispherical structure 33 can be expanded to the contraction end 141, and then extend from the opening at the end of the contraction end 141, then the side wall at the end of the contraction end 141 can be abutted against the side wall of the hollow hemispherical structure 33 facing the hollow joint, in this way, the phenomenon of liquid leakage can be prevented.

[0029] Further, as shown in Figure 4 In order to prevent the phenomenon of falling off between the dressing and the dressing hollow joint one 12 and the dressing hollow joint two 31, the end of the dressing hollow joint one 12 and the dressing hollow joint two 31 is provided with an anti-falling expansion part 34 in the radial direction, after the dressing hollow joint one 12 and the dressing hollow joint two 31 pass through the preset hole of the dressing, the upper side plate of the anti-falling expansion part 34 is abutted against the top wall in the preset hole, in this way, the phenomenon of falling off between the dressing and the dressing hollow joint one 12 and the dressing hollow joint two 31 can be prevented.

[0030] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
