Description

Technical Field

[0001] This utility model relates to the field of hospital supplies, and in particular to an eye irrigation device. Background Technology

[0002] Disposable infusion sets are commonly used as tools for ophthalmic irrigation. The method of use involves removing or cutting off the needle from the infusion set, leaving the infusion tubing as the irrigation tube; hanging the saline bag for irrigation, for example, on an existing IV stand; connecting the infusion set to the saline bag; and turning on the infusion set's flow regulator, allowing the saline solution to flow from the tubing under gravity to irrigate the patient's eye. This irrigation method utilizes the very common medical consumable, the disposable infusion set, which is readily available; it is easy to operate as long as the infusion tubing is held against the eye; and the flow regulator on the infusion set can also adjust the irrigation water flow rate. Currently, this irrigation method is widely used in situations where a high irrigation water flow rate is not required. It is also documented in literature such as "Application of Disposable Infusion Sets in Preoperative Irrigation of the Conjunctival Sac in Ophthalmology," published in Nursing Practice and Research, Vol. 14, No. 2, 2017.

[0003] Using disposable infusion sets for ophthalmic irrigation also has some drawbacks. Firstly, using disposable infusion sets for ophthalmic irrigation is wasteful if done only once. The amount of water used for each irrigation is small; one bag of saline solution can be used for multiple patients, and changing the disposable set after each irrigation is cumbersome. Therefore, currently, one disposable infusion set is often used for multiple patients' eye irrigation. However, during irrigation, the tip of the infusion tubing must be 3-4 cm away from the eyeball. This close proximity, coupled with the person holding the tubing to control the distance, inevitably reduces the distance further, thus raising the possibility of irrigation water splashing onto the tubing tip. If the tubing is contaminated with pathogens from previous patients, using it for the next patient's irrigation could lead to the spread of pathogens. Secondly, because one disposable infusion set is often used for multiple patients' eye irrigation, the infusion tubing needs to be properly stored during the intervals between irrigations to prevent contamination of the tip. However, there is currently a lack of suitable items for properly storing infusion tubing during these intervals. Utility Model Content

[0024] The needle-free infusion set 3 is an existing disposable infusion set with the needle removed. It includes a plug for connecting the fluid bag 2, a fluid tubing, and a speed controller mounted on the fluid tubing. Preferably, it is an infusion set where the needle part is threadedly connected to the fluid tubing. After the needle part is removed, the fluid tubing has an internal thread, and the handle 4-1 has a corresponding external thread for connection to the needle-free infusion set 3. The support 1 can be an existing infusion stand.

[0025] This invention mainly adds a rinsing handle 4 and a rinsing head 5-1 to the existing technology. The rinsing head 5-1 is for single use and can be made of a small plastic part, which is very low in cost and hardly increases the rinsing cost. Since the rinsing head 5-1 is for single use, there is no need to worry about rinsing water adhering to the rinsing head 5-14, which will not lead to the spread of germs and improve the safety of eye rinsing.

[0026] When replacing the flushing head 5-1, push the sliding sleeve 4-2 forward with the thumb of the hand holding the handle 4-1. The sliding sleeve 4-2 moves forward and pushes down the flushing head 5-1. Then, holding the handle 4-1, forcefully insert the connecting post 4-1-1 into the new flushing head 5-1 inside the flushing head box 5-2, thus completing the replacement of the flushing head 5-1. This operation is convenient and avoids contamination of the flushing head and contact with any germs that may be carried on it.
