[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference below Figure 1-5 , the implementation of the flushing needle proposed in the embodiment of the utility model is described in detail.

[0029] The flushing needle according to the embodiment of the utility model comprises: a piercing portion 1 and a liquid outlet portion 2 .

[0030] Specifically, the piercing portion 1 defines a first liquid inlet hole 11, and the first liquid inlet hole 11 is arranged near the upper end of the piercing portion 1; the liquid outlet portion 2 has a shell 21, a flushing hose 22, a blocking member 23 and a protective cover 24, the flushing hose 22 is arranged in the shell 21, one end of the flushing hose 22 is connected to the piercing portion 1 and is connected to the first liquid inlet hole 11, and the other end of the flushing hose 22 extends out of the shell 21, the blocking member 23 can be slidably arranged on the shell 21 to approach or move away from the flushing hose 22 so that the liquid in the flushing hose 22 is blocked, circulated or flow-regulated, and the protective cover 24 can be flipped on the shell 21 so that the protective cover 24 can be switched between an open state and a closed state. In the open state, the protective cover exposes the flushing hose 22 and extends it out of the shell 21, and in the closed state, the protective cover 24 bends the flushing hose 22 in the shell 21.

[0031] That is to say, the piercing portion 1 is suitable for piercing from the bottle mouth of the medicine bottle, and the first liquid inlet hole 11 is arranged near the upper end of the piercing portion 1, so that the first liquid inlet hole 11 is located near the bottle mouth of the medicine bottle in the medicine bottle, which is convenient for the medicine liquid to enter the first liquid inlet hole 11 and then be fully discharged from the flushing hose 22, thereby avoiding waste of medicine liquid. When it is necessary to flush the patient's conjunctival sac, the blocking member 23 is slid away from the flushing hose 22, so that the medicine liquid in the flushing hose 22 is in a flowable state, and the medicine liquid is adjusted to a suitable flow rate, and then the protective cover 24 is opened to make the flushing hose 22 extend out of the shell 21, and then the medicine liquid is discharged from the outlet of the flushing hose 22 by squeezing the medicine bottle. When flushing is completed, the blocking member 23 is slid close to the flushing hose 22, so that the flushing hose 22 is squeezed to block the medicine liquid in the flushing hose 22, and then the protective cover 24 is closed. The protective cover 24 bends the flushing hose 22 inside the shell 21, thereby avoiding contact between the flushing hose 22 and the outside and causing contamination.

[0032] Therefore, by arranging the first liquid inlet hole 11 near the upper end of the piercing part 1, when the piercing part 1 is inserted into the medicine bottle, the first liquid inlet hole 11 is located near the bottle mouth of the medicine bottle, which is convenient for fully emptying the liquid medicine in the medicine bottle, thereby avoiding waste of the liquid medicine; in the flushing state, the liquid medicine in the flushing hose 22 is circulated through the blocking piece 23 of the liquid outlet 2, and the flow rate of the liquid medicine is adjusted, and then the protective cover 24 is opened to make the flushing hose 22 extend out of the shell 21, so as to facilitate flushing of the patient's conjunctival sac; when not in use, the liquid medicine in the flushing hose 22 is blocked by the blocking piece 23, and then the protective cover 24 is closed, so that the flushing hose 22 is bent inside the shell 21, thereby avoiding contact with the outside and causing contamination.

[0033] The blocking member 23 defines a roller 231 , and the housing 21 defines an inclined first slide groove 211 and a sliding space 212 . The roller 231 is slidably connected to the first slide groove 211 , and a portion of the roller 231 extends out of the sliding space 212 . It can be understood that, by the cooperation between the roller 231 and the inclined first slide groove 211, it is convenient for the roller 231 to approach and squeeze the flushing hose 22 so that the flushing hose 22 is squeezed to block the liquid medicine or adjust the flow of the liquid medicine, and at the same time, it is convenient for the roller 231 to move away from the flushing hose 22 so that the flushing hose 22 is released from the squeezed state, and the liquid medicine in the flushing hose 22 can flow. At the same time, the roller 231 is set, and the sliding can be switched to rolling in the process of the roller 231 squeezing the flushing hose 22, so that the flushing hose 22 is fully squeezed, and the reliability of the liquid medicine being blocked can be ensured. In addition, by partially extending the roller 231 from the sliding space 212, it is convenient for the finger to push and pull the roller 231, so as to realize the rapid switching of the blocking state and the circulation state of the liquid medicine in the flushing hose 22 and the precise adjustment of the liquid medicine flow. Among them, the roller 231 can be provided with anti-skid patterns to increase the friction between the roller 231 and the flushing hose 22, and the friction between the roller 231 and the finger.

[0034] For the realization of the flipping of the protective cover 24, the protective cover 24 is connected to a lever 25, and when the lever 25 is toggled, the protective cover 24 can be switched between an open state and a closed state. It can be understood that in some embodiments, the protective cover 24 can be switched between an open state and a closed state by manually toggling the lever 25, so as to avoid the operator's hand from directly contacting the protective cover 24 and causing contamination. Among them, the lever 25 can be integrally formed with the protective cover 24, and the lever 25 can be provided with anti-slip textures to facilitate easier opening or closing of the protective cover 24. The protective cover 24 and the housing 21 can be matched by a torsion spring or a damping match, so that the protective cover 24 maintains this state when it is opened, thereby avoiding interference with the flushing hose 22 during flushing. The flipping angle of the protective cover 24 can be greater than 180°.

[0035] Regarding the cooperation between the protective cover 24 and the housing 21 when the protective cover 24 is in the closed state, the housing 21 defines a receiving groove 213, and the protective cover 24 defines a first abutting surface 241 and a second abutting surface 242. When in the closed state, the first abutting surface 241 abuts against the flushing hose 22 to bend the flushing hose 22 in the receiving groove 213, and the second abutting surface 242 fits the bottom surface of the receiving groove 213. It can be understood that during the closing process of the protective cover 24, the first abutting surface 241 abuts against the flushing hose 22 portion extending out of the housing 21, and gradually bends the flushing hose 22 between the first abutting surface 241 and the receiving groove 213 until the second abutting surface 242 fits the bottom surface of the receiving groove 213, thereby making the flushing hose 22 completely enclosed in the housing 21, thereby avoiding contamination of the flushing hose 22. Among them, the first abutting surface 241 and the second abutting surface 242 are integrally formed on the protective cover 24, and the receiving groove 213 is integrally formed on the housing 21.

[0036] For the realization of the flipping of the protective cover 24, the liquid outlet 2 includes a push-pull member 26, the housing 21 defines a second slide groove 214, the push-pull member 26 is slidably disposed in the second slide groove 214, and the push-pull member 26 is hinged to the protective cover 24. It can be understood that in another embodiment, the protective cover 24 can be pushed and pulled to switch between the closed state and the open state through the cooperation of the push-pull member 26 and the second slide groove 214, so that the operator's hand is further away from the protective cover 24, thereby further avoiding the contact of the fingers with the protective cover 24 and causing contamination of the protective cover 24 or the flushing hose 22. Among them, the push-pull member 26 can be hinged to one end of the connecting rod 27, and the other end of the connecting rod 27 is hinged to the protective cover 24, and the flipping angle of the protective cover 24 can be greater than 180°.

[0037] The piercing portion 1 is provided with a second liquid inlet hole 12 which is in communication with the first liquid inlet hole 11, and the second liquid inlet hole 12 is provided at the bottom of the piercing portion 1. It can be understood that by providing the second liquid inlet hole 12, it is convenient to increase the amount of liquid outflow from the medicine bottle, and combined with the adjustment of the blocking member 23, it can meet the flushing mode of different amounts of liquid medicine. Among them, the piercing portion 1 can be made of plastic or metal, the first liquid inlet hole 11 and the second liquid inlet hole 12 are integrally formed on the piercing portion 1, and the number of the first liquid inlet hole 11 can be two which are arranged oppositely.

[0038] For the process of piercing the medicine bottle, a pressing part 3 is also included, and the pressing part 3 is arranged between the shell 21 and the piercing part 1. It can be understood that since the bottle stopper of the medicine bottle is generally made of rubber or silicone, a large force needs to be applied during the piercing process. By setting the pressing part 3, it is convenient for the fingers to apply force to it, so that the piercing part 1 can pierce the bottle stopper or pull it out more easily, and at the same time, it can prevent the operator's hand from contacting the position near the discharge of the liquid medicine, avoiding contamination of the area where the liquid medicine is discharged. Among them, the pressing part 3 can be integrally formed with the shell 21.

[0039] To maintain the closed state of the protective cover 24, the protective cover 24 and the housing 21 are magnetically attached to each other in the closed state. It can be understood that the magnetic attachment of the protective cover 24 and the housing 21 can facilitate the protective cover 24 to maintain the closed state in the closed state, and avoid the flushing hose 22 exerting a force on the protective cover 24 to open the protective cover 24, thereby ensuring the reliability of the protective cover 24 maintaining the closed state. Among them, the magnetic attraction member can be set on the protective cover 24, and the housing 21 can be set with a magnetic attraction member or a metal member, so that the protective cover 24 attracts each other when it is close to the housing 21.
