Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-4The utility model provides a technical solution: a wound irrigator with adjustable length, including a graduated cylinder 1, a cylinder 2, a irrigating head 3, a liquid inlet pipe 4, a drainage port 5, a liquid outlet pipe 6, a push plate 7, a connecting rod 1 8, a connecting rod 2 9, a piston 10, a piston 2 11, a one-way valve 1 12, a one-way valve 2 13, a hose 14, a rack 15, a gear 16, a buckle 1 17, a buckle 2 18, and a magnet 19.

[0031] This device has the effect of fixing the storage bag and adjusting the length, specifically:

[0032] An adjusting structure is arranged on the surface of the cylinder 2, and the adjusting structure uses a rack 15 to adjust the length of the device. The adjusting structure includes the rack 15, one end of which is connected to one side of the graduated cylinder 1, and the rack 15 is slidably connected to the surface of the cylinder 2, and a gear 16 is arranged on the surface of the cylinder 2, and the gear 16 is meshed with the rack 15. A fixing structure is arranged on the surface of the liquid outlet tube 6, and the fixing structure uses a buckle 17 to fix the storage bag, and the fixing structure includes a buckle 17, and the buckle 17 is rotatably mounted on the surface of the cylinder 2, and a buckle 2 18 is rotatably mounted on the surface of the cylinder 2, and the buckle 17 and the buckle 2 18 are both semicircular, and magnets 19 are arranged at both ends of the buckle 17 and the buckle 2 18;

[0033] like Figure 1 , connect the liquid medicine tube to the liquid inlet tube 4, and at the same time, sleeve the storage bag on the outer surface of the liquid outlet tube 6, such as Figure 4 , rotate the buckle 17 and the buckle 2 18, align the left and right ends of the buckle 17 with the buckle 2 18 respectively, and the magnets 19 on both sides further fix the buckle 17 and the buckle 2 18. At this time, the storage bag is fixed to the liquid outlet tube 6, as shown in FIG. Figure 2 , rotate the gear 16 counterclockwise, the gear 16 drives the rack 15 to move rightward, the rack 15 drives the graduated cylinder 1 to slide rightward on the outer surface of the cylinder 2, and the length of the device is reduced. Conversely, rotate the gear 16 clockwise, the gear 16 drives the rack 15 to move leftward, and drives the graduated cylinder 1 to slide leftward to extend the device. Due to the presence of the hose 14, the sliding of the graduated cylinder 1 will not affect the transportation of the liquid medicine and the flushing material.

[0034] The device has the effect of collecting the flushed material while flushing, specifically:

[0035] The inner wall of the graduated cylinder 1 is slidably connected with a cylinder 2, and the interior of the cylinder 2 is divided into two chambers. A flushing head 3 is provided on one side of the graduated cylinder 1, and a liquid inlet pipe 4 is provided on the surface of the cylinder 2. A drainage port 5 penetrates the surface of the graduated cylinder 1, and a liquid outlet pipe 6 is provided on the surface of the cylinder 2. A connecting rod 1 8 and a connecting rod 2 9 are provided on one side of the push plate 7. The connecting rod 1 8 penetrates the surface of the cylinder 2, and a piston 10 is provided at one end of the connecting rod 1 8. The connecting rod 2 9 penetrates the surface of the cylinder 2 and is connected to a piston 2 11. The plug 10 and the piston 2 11 are respectively located in the two chambers of the cylinder 2. A one-way valve 12 is provided in one of the chambers of the cylinder 2. A hose 14 is provided at one end of the one-way valve 12, and the other end of the hose 14 is connected to the flushing head 3. The flow direction of the one-way valve 12 is from the cylinder 2 to the graduated cylinder 1. A one-way valve 2 13 is provided in the other chamber of the cylinder 2. A hose 14 is provided at one end of the one-way valve 13 and is connected to the drainage port 5. The flow direction of the one-way valve 2 13 is from the graduated cylinder 1 to the cylinder 2.

[0036] like Figure 1 and Figure 3 , extend the graduated cylinder 1 into the wound, pull the push plate 7 to the right, the push plate 7 drives the connecting rod 1 8 and the connecting rod 2 9 to move to the right, the connecting rod 1 8 drives the piston 10 to move to the right, so that the medicine is drawn into the cylinder 2 from the liquid inlet pipe 4. When the push plate 7 is pushed to the left, the push plate 7 drives the piston 10 to move to the left, and the medicine is pushed out from the one-way valve 12, and flows out from the flushing head 3 through the hose 14 to flush the wound. At the same time, when the connecting rod 2 9 drives the piston 2 11 to move to the left, since the direction of the one-way valve 2 13 is from the graduated cylinder 1 to the cylinder 2, no liquid will pass through the drainage port 5 at this time. When the push plate 7 moves to the right again, the push plate 7 drives the piston 2 11 to move to the right, and the flushing material of the wound is drawn into the cylinder 2 from the drainage port 5. When the push plate 7 moves to the left again, the flushing material is pushed out of the cylinder 2 into the liquid outlet pipe 6 and collected in the storage bag.

[0037] Working principle: When using the wound irrigator with adjustable length, connect the medicine liquid to the liquid inlet tube 4, and fix the storage bag to the outer surface of the liquid outlet tube 6 by means of buckle 17 and buckle 2 18. The gear 16 drives the rack 15 to move, which can drive the graduated cylinder 1 to slide on the surface of the cylinder 2, thereby adjusting the length of the device. The graduated cylinder 1 is inserted into the wound, and the push plate 7 is repeatedly pushed and pulled. The push plate 7 drives the connecting rod 1 8 and the connecting rod 2 9 to move, thereby driving the piston 1 10 and the piston 2 11 to move, so as to achieve the effect that the medicine liquid is used to flush the wound by the flushing head 3 and the flushed material is collected by the drainage port 5, thereby increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
