Detailed Description

In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.

Under the condition of the existing apparatus, the conjunctival sac irrigation process has the following defects: 1. the puncture outfit of the disposable infusion apparatus is not used, most of medical staff use the puncture outfit of the disposable infusion apparatus for puncture infusion, which is relatively wasteful, and has sharp cut, no question of matching and lower safety performance; 2. the required flushing amount of each patient is different, but no good sealing device is provided to prevent the mouth of the flushing liquid from being polluted, so that the flushing liquid cannot be stored, and much waste is caused; 3. the existing apparatus is not easy to pull out.

Specifically, referring to fig. 1-5, the disposable conjunctival sac washing head is adapted to a washing liquid bottle and used for washing conjunctival sac, and comprises a puncture tube 1, wherein the puncture tube 1 is used for being inserted into a bottle stopper 31 of the washing liquid bottle, an end cover 11 is arranged at the other end of the puncture tube 1, a water outlet hose 12 communicated with the puncture tube 1 is arranged on the other surface of the end cover 11, an air filter 13 is connected to the side wall of the water outlet hose 12, and the water outlet hose 12 is communicated with the air filter 13; the other end of the water outlet hose 12 is provided with a water outlet 121; the water purifier also comprises a sealing cover 2 detachably connected with the end cover 11, and a water outlet hose 12 and an air filter 13 are accommodated in an accommodating cavity formed by the sealing cover 2 and the end cover 1; the puncture tube such as a bottle stopper puncture outfit is generally provided with a sharp-pointed hard component which can be directly inserted through a bottle stopper, then flushing fluid flows into the water outlet hose from the puncture tube and then flows out from the water outlet, and the sealing cover can be in clamping connection, threaded connection, flip connection and the like, so that the water outlet hose and the air filter can be directly covered by the sealing cover when the flushing fluid is not used up, and then infection prevention storage for a certain time can be achieved; wherein air cleaner is in order to guarantee with outside atmosphere intercommunication in the bottle, and it is more convenient to wash.

In the embodiment, the end cap 11 extends to one side of the bottle stopper to form a snap strip 111, and the snap strip 111 is in frictional contact with the outer mouth of the washing liquid bottle to form a clamping structure; the buckle strip can be elastic plastic or an elastic plastic strip and is buckled by using the elastic restoring force of the buckle strip.

In this embodiment, the snap strips 111 are evenly distributed along the side wall of the end cap.

In this embodiment, one side of the buckling strip 111 close to the bottle stopper is provided with a plastic spring piece, the plastic spring piece forms a bending structure, the plastic spring piece is buckled by restoring force of the plastic spring piece, and the plastic spring piece can also be deformed to facilitate the pulling out when being pulled out.
