Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a conjunctival sac irrigator for ophthalmology. Background Art

[0002] Conjunctival sac irrigation is a commonly used treatment method in ophthalmology clinics, which can achieve the purposes of cleaning foreign bodies and secretions in the conjunctival sac, cleaning and sterilizing, irrigating chemical burns of the eyes, and neutralizing chemical substances.

[0003] At present, most hospitals use two methods for irrigation: one is to use a professional eye washing device, an eye wash pot for eye washing, but the capacity of the eye wash pot is limited. If a large amount of irrigation is required, the bottle cap needs to be repeatedly opened to supplement the irrigation solution. The other is eye washing with an infusion set. When using it, the infusion tube and the normal saline bottle need to be assembled, and operations such as exhausting air and removing the needle head of the infusion tube are required. The process is numerous and time-consuming, and the infusion tube is relatively long, and the pressure during irrigation is small, which affects the irrigation effect.

[0004] Therefore, this patent provides a conjunctival sac irrigator for ophthalmology that can conveniently and quickly irrigate the eyes and ensure the irrigation effect. Summary of the Utility Model

Detailed implementation manners

[0027] Referring to an embodiment herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] Embodiment 1

[0029] Please refer to Figures 1 - 5, An ophthalmic conjunctival sac irrigator, including a liquid storage barrel 1. A silica gel sleeve for buffering and anti-slip is sleeved on the surface of the liquid storage barrel 1, which can protect the liquid storage barrel 1 when the device falls to the ground. A fixing frame 18 is arranged outside the liquid storage barrel 1, and a number of hooks 19 are arranged on the fixing frame 18. Various instruments can be hung by using the hooks 19, which is convenient for medical staff to pick up and use. A protective cover plate 2 is arranged at the top of the liquid storage barrel 1. The protective cover plate 2 is made of flexible plastic material and has better sealing performance. At the top of the protective cover plate 2, liquid supplement tubes 201 symmetrically distributed left and right are arranged. A protective shell 20 is arranged at the top end of the liquid supplement tube 201. The protective shell 20 is used to seal the liquid supplement tube 201 to prevent foreign objects from entering the pipeline. Symmetrically distributed cavities 3 are arranged inside the liquid storage barrel 1. Symmetrically distributed first infusion tubes 4 are arranged outside the liquid storage barrel 1. The two first infusion tubes 4 are respectively communicated with the two cavities 3. A ball valve 401 is arranged at the lower end of the first infusion tube 4. Two water pumps 6 for pressurized extraction of medicine are arranged outside the liquid storage barrel 1 through a mounting frame 5. The liquid inlet end of the water pump 6 is communicated with the upper end of the adjacent first infusion tube 4. The liquid outlet ends of the two water pumps 6 are jointly connected with a connecting pipe 7. A second infusion tube 8 is connected to the connecting pipe 7. The second infusion tube 8 is a flexible tube, which is convenient for movement. A eye wash pot 9 is arranged on the second infusion tube 8. A collar 801 is sleeved on the second infusion tube 8. A connecting hose 802 is connected to the collar 801. A collection box 803 is installed at the other end of the connecting hose 802. One side of the collection box 803 is an arc surface, which can make the collection box 803 fit the patient's face. An elastic band 804 is installed between the two sides of the collection box 803.

[0030] This device has two usage methods for cleaning foreign objects and secretions in the ordinary conjunctival sac and flushing eye chemical injuries. Before conjunctival sac flushing, first stretch the elastic band 804 and put it on the patient's head, so that the arc surface side of the collection box 803 is closely attached to the patient's cheek. When cleaning foreign objects and secretions in the ordinary conjunctival sac, open the protective cover plate 2 and pour sufficient physiological saline into the two cavities 3. Then the protective cover plate 2 is reset. Move the eye wash pot 9 above the eyeball to be irrigated, 3-4 cm away from the eyeball. By opening the ball valve 401, the water pump 6 pressurizes the medicine and pumps it into the eye wash pot 9 for preliminary cleaning and eye flushing operations. For eye chemical injury flushing, pour physiological saline and neutralizing solution into the two cavities 3 respectively. The eye wash pot 9 is also moved to a position 3-4 cm away from the eyeball. First, open the ball valve 401 on the side filled with physiological saline for preliminary cleaning operations. During the conjunctival sac flushing operation, the waste liquid after flushing flows into the collection box 803 along the patient's canthus. The collection box 803 collects the waste liquid. Then close and open the ball valve 401 on the other side to extract the neutralizing solution for flushing operations.

[0031] Embodiment 2

[0032] Based on Embodiment 1, please refer to Figure 6 , a sandwich layer is provided on the liquid storage barrel 1, and a heating pipe 11 for heating the medicament is arranged in the sandwich layer. The heating pipe 11 is arranged in a spiral shape to increase the heating area and ensure uniform heating. Both ends of the heating pipe 11 penetrate through the liquid storage barrel 1. One end of the heating pipe 11 is provided with a temperature control switch 10, and the other end is provided with a temperature display instrument 13. The display instrument is fixed outside the liquid storage barrel 1 through a positioning bracket 12. During use, the temperature control switch 10 is turned on to operate the heating pipe 11 to heat the internal medicament to 32-37 degrees, reducing the irritation of the medicament to the eyes and improving the comfort during flushing.

[0033] Please refer to Figure 7 , a gear 14 is arranged on the ball valve 401. A guide plate 17 is arranged on one side of the liquid storage barrel 1 close to the gear 14. A connecting rod 16 is slidably arranged on the guide plate 17. A rack 15 is fixedly connected to the connecting rod 16. The rack 15 is matched with the gear 14 in model and meshes with each other. By pulling the rack 15 to move, the two gears 14 can drive the ball valve 401 to rotate. In this way, one side ball valve 401 can be closed while the other side ball valve 401 is opened, which is more convenient to use.
