Description

Technical Field

[0001] The invention relates to the technical field of eye wound flushing, and in particular to an eye wound flushing device. Background Art

[0002] In wars and non-war military operations, combatants' bodies are often injured due to the complex and changeable battlefield environment, among which eye injuries account for a large proportion, which are mainly divided into two types: acid and alkali burns and traumatic damage. If the injury can be determined in time before treating the wounded, and important parts can be stopped and disinfected, it will play a key role in the treatment of the wounded. Otherwise, the wounded will become blind and leave them with lifelong pain.

[0003] For example, the patent with announcement number CN215607585U discloses a multifunctional portable eye and trauma irrigator. The working principle of the device is as follows: when people need to use the irrigator to irrigate the wound, turn on the micro air pump, and the micro air pump will inflate the air into the inflation tube. When the pressure in the inflation tube is greater than the pressure in the irrigating bottle and the spring force, the sealing plug will move to the left, and the sealing plug will be separated from the inflation tube. The gas in the inflation tube will be filled into the top of the tray and drive the tray and the scraper to move downward. The downward movement of the tray will squeeze the cleaning liquid in the irrigating bottle, so that the cleaning liquid is discharged from the irrigating bottle through the conduit and nozzle and cleans the wound.

[0004] However, since the nozzle outlet of this device is small, when flushing the eye wound, the nozzle often needs to be moved manually to fully clean the eye wound, which is rather troublesome. Summary of the invention

[0005] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is that when the existing eye wound flushing device flushes the eye wound, it is often necessary to manually move the nozzle to fully clean the eye wound, which is rather troublesome.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: an eye injury flushing device, comprising:

[0009] A nozzle is disposed in the liquid channel, wherein the liquid inlet end of the nozzle is hinged to the flushing body, and the liquid outlet end of the nozzle faces the liquid outlet; and the liquid in the liquid channel flows to the liquid outlet through the nozzle; and

[0010] The driving mechanism is used to drive the spray head to swing back and forth by the liquid flowing through the liquid inlet toward the liquid outlet in the liquid channel.

[0011] Preferably, the driving mechanism comprises: a rotating member, a cylindrical member and a rocker; the rotating member is rotatably installed in the liquid channel, and the flow of liquid in the liquid channel through the liquid inlet toward the liquid outlet can drive the rotating member to rotate; one end of the cylindrical member is eccentrically fixed to the rotating member; one end of the rocker is fixedly connected to the nozzle, and the extension line of the rocker in the length direction intersects with the hinge axis of the nozzle; a slide groove is provided on the side of the other end of the rocker, and the end of the cylindrical member away from the rotating member extends into the slide groove.

[0012] Preferably, the rotating member is located between the liquid inlet and the nozzle, and the rotating member includes: a rotating shaft, fan blades and side plates; one end of the rotating shaft extends into the liquid channel, and the rotating shaft is rotatably connected to the flushing body; multiple fan blades are rotatably installed on the rotating shaft in the liquid channel; and the multiple fan blades are arranged in a circular array with the axis of the rotating shaft as the center; side plates are respectively provided at both ends of the fan blades, and the two side plates are fixedly connected to the multiple fan blades; the cylindrical member is fixedly installed on the side plate away from the rotating shaft.

[0013] Preferably, the liquid inlet faces a tangential direction of the rotating shaft.

[0014] Preferably, it also includes handles, which are fixedly installed on opposite sides of the flushing body, and the handles are arranged along the length direction of the rotating shaft. One end of the rotating shaft away from the cylindrical member extends into one of the handles, and the rotating shaft and the handle are rotatably connected.

[0015] Preferably, the liquid delivery mechanism comprises: a liquid storage tank, a piston and a pushing assembly; the liquid storage tank is installed on the flushing body, and the liquid storage tank is connected to the flushing body; the piston is slidably installed in the liquid storage tank, and the pushing assembly can push the piston to slide.

[0016] Preferably, the pushing assembly includes: a screw rod, a nut seat and a motor; the screw rod is rotatably installed in the liquid storage tank, and the screw rod is arranged along the sliding direction of the piston; the nut seat is fixedly installed on the piston, and the nut seat is threadedly connected to the screw rod; the motor can drive the screw rod to rotate.

[0017] Preferably, it also includes a collecting mechanism, which includes: a waste liquid tank, a silicone cover, a connecting pipe and a pump body; the waste liquid tank is installed on the flushing body, and the liquid storage tank is connected to the silicone cover through a connecting pipe; the silicone cover is fixedly installed at one end of the flushing body close to the liquid outlet, and the liquid outlet is located in the silicone cover; the pump body is installed on the connecting pipe.

[0021] 2. In the present invention, two handles are provided, so that the flushing body can be held more conveniently, and since only one end of the rotating shaft is rotatably installed in the flushing body, the rotating shaft is prone to tilting and deviation; by extending the rotating shaft into the handle, the rotating shaft can be effectively limited to prevent the rotating shaft from tilting and deviation.

The liquid delivery mechanism 2 delivers liquid toward the liquid inlet 11, and the liquid enters the liquid channel 13, and then enters the nozzle 3 through the liquid inlet end of the nozzle 3, and is sprayed out through the liquid outlet end of the nozzle 3. In this way, the liquid can be sprayed out through the liquid outlet 12 to rinse the wound on the eye; at the same time, the liquid passes through the driving mechanism 4, and the driving mechanism 4 drives the nozzle 3 to reciprocate under the drive of the liquid, so that the flushing range of the nozzle 3 can be expanded, thereby replacing the manual movement of the nozzle, and the operation is more convenient.

[0033] See also Figure 1-Figure 3 In other embodiments, the driving mechanism 4 includes: a rotating member, a cylindrical member 44 and a rocker 45; the rotating member is rotatably installed in the liquid channel 13, and the liquid in the liquid channel 13 flows through the liquid inlet 11 toward the liquid outlet 12, which can drive the rotating member to rotate; one end of the cylindrical member 44 is eccentrically fixed on the rotating member; one end of the rocker 45 is fixedly connected to the nozzle 3, and the extension line of the rocker 45 in the length direction intersects with the hinge axis of the nozzle 3; a slide groove 46 is opened on the side of the other end of the rocker 45, and the end of the cylindrical member 44 away from the rotating member extends into the slide groove 46.
