[0044] The following will clearly and completely describe the technical solutions in the embodiments in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only some of the embodiments, rather than all of the embodiments.

[0045] Embodiment 1

[0046] AsFigures 1 to 3 As shown in Figures 1 to 3 , this embodiment discloses a wound irrigator, which includes an injection container 10, a piston 20, an infusion tube 30, and a driving mechanism 40.

[0047] Specifically, the injection container 10 has an irrigation tube 11.

[0048] Specifically, the piston 20 is disposed within the injection container 10, and the piston 20 is configured to form a liquid chamber 12 with the injection container 10. The driving mechanism 40 is used to drive the piston 20 to axially move, thereby compressing or expanding the volume of the liquid chamber 12 to achieve the pumping and discharging of physiological saline.

[0049] Specifically, one end of the infusion tube 30 is configured to be connected to a physiological saline bottle. One end of the irrigation tube 11 is configured to communicate with the liquid chamber 12, and the other end of the infusion tube 30 is configured to be connected to the irrigation tube 11.

[0050] Exemplarily, the infusion tube 30 has a puncture tube that communicates with the infusion tube 30. The puncture tube can pierce the rubber stopper of the physiological saline bottle and enter the physiological saline bottle, so that the physiological saline can enter the infusion tube 30.

[0051] Specifically, a first one-way valve 50 is disposed on the irrigation tube 11, and a second one-way valve 60 is disposed on the infusion tube 30. The second one-way valve 60 is located between the first one-way valve 50 and the piston 20.

[0052] During use, the first one-way valve 50 and the second one-way valve 60 cooperate with each other to allow the liquid chamber 12 to draw only physiological saline from the infusion tube 30 when the driving mechanism 40 drives the piston 20 to expand the volume of the liquid chamber 12.

[0053] During use, the first one-way valve 50 and the second one-way valve 60 cooperate with each other to allow the physiological saline in the liquid chamber 12 to be discharged only from the irrigation tube 11 when the driving mechanism 40 drives the piston 20 to compress the volume of the liquid chamber 12.

[0054] During use, continuous wound irrigation can be achieved without replacing the irrigator, and the entire irrigator does not have a needle, so the safety is relatively high. When replenishing physiological saline, only the piston 20 needs to be controlled to draw physiological saline from the physiological saline bottle connected to the infusion tube 30. The convenience is good, and physiological saline bottles with different capacities can be selected according to the area of the wound, so the flexibility is good.

[0055] In this embodiment, a water distributor 70 is provided at the other end of the irrigation tube 11. The water distributor 70 is configured to be detachably connected to the irrigation tube 11. By configuring the water distributor 70, the irrigation area can be increased and the irrigation efficiency can be improved.

[0056] Specifically, the water distributor 70 includes a container that communicates with the irrigation tube 11, and a plurality of water outlet holes are provided on the container.

[0057] In this embodiment, the injection container 10 is made transparent, which can facilitate the user to observe the volume of the physiological saline in the liquid chamber 12 and improve convenience.

[0058] In this embodiment, a handle 13 is fixedly arranged on the outer wall of the injection container 10. By arranging the handle 13, it is convenient for the staff to hold the injection container, and the convenience is good.

[0059] In this embodiment, a clamping mechanism 17 is arranged on the outer wall of the injection container 10. The clamping mechanism 17 is used to clamp the infusion tube 30, which has the effect of positioning and guiding the infusion tube 30, and can prevent the infusion tube 30 from shaking during the flushing operation and affecting the flushing.

[0060] Exemplarily, the clamping mechanism includes a seat body, and a clamping groove is arranged on the seat body. The clamping groove is in interference fit with the infusion tube 30, and the infusion tube 30 can be clamped in the clamping groove to achieve fixation.

[0061] In this embodiment, the driving mechanism 40 includes an air pump assembly 41 and an air pipeline 42.

[0062] Specifically, a gas chamber 14 is further formed between the piston 20 and the injection container 10. The gas chamber 14 and the liquid chamber 12 are separated by the piston 20. One end of the air pipeline 42 is configured to communicate with the gas chamber 14, and the other end of the air pipeline 42 is configured to communicate with the air pump assembly 41.

[0063] Specifically, the air pump assembly 41 can adjust the air pressure in the gas chamber 14 by pumping air into or exhausting air from the gas chamber, so as to drive the piston 20 to axially move.

[0064] Exemplarily, the air pump assembly 41 includes an air extraction pump and an air exhaust pump, and the air pipeline 42 is a three-way air pipe. Two of the ports of the three-way air pipe are respectively connected to the air extraction pump and the air exhaust pump, and the remaining one port of the three-way air pipe is connected to the injection container 10. In order to ensure the air extraction and exhaust of the air extraction pump and the air exhaust pump, third one-way valves 43 are arranged on both of the two passages of the three-way air pipe connected to the air extraction pump and the air exhaust pump.

[0065] Specifically, the injection container 10 includes a cylinder body 15 and an end cover 16. The cylinder body 15 and the end cover 16 are threadedly connected, and a sealing rubber ring 18 is arranged between the cylinder body 15 and the end cover 16. The flushing pipe 11 is integrally provided with the cylinder body 15.

[0066] Embodiment 2

[0067] As Figure 4 shown, this embodiment discloses a wound irrigator, which is different from Embodiment 1 in that the driving mechanism 40 is a push rod.

[0068] Specifically, one end of the infusion tube 30 is configured to be connected to a normal saline bottle. One end of the flushing tube 11 is configured to communicate with the liquid chamber 12, and the other end of the infusion tube 30 is configured to be connected to the injection container 10.

[0069] Exemplarily, one end of the injection container 10 has a through hole (not shown), one end of the push rod is configured to be fixedly connected to the piston 20, and the other end of the push rod is configured to pass through the through hole and extend outside the injection container 10. The overall structure is similar to that of a common syringe barrel and piston rod, and it has good usability.

[0070] Although the embodiments of the present application have been shown and described above, the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work shall be covered within the protection scope of the present utility model; unless otherwise clearly stated, any element, action or instruction used in this article shall not be construed as critical or necessary.
