Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an eye flushing device. Background Art

[0002] When foreign matter enters the eye, especially a large amount of irritating chemicals, the eye must be quickly rinsed with a large amount of normal saline. During the rinse, the conjunctival sac needs to be fully exposed, and the upper and lower eyelids need to be turned over to directly flush out the foreign matter, reduce the possibility of foreign matter remaining on the conjunctiva and cornea, and prevent further damage to the eye. The eye can generally be rinsed with water, normal saline, tobramycin eye drops and other drugs. The purpose is to eliminate inflammation of the eye and at the same time play a cleaning role. The eye also needs to be cleaned before eye surgery. The purpose is to reduce the residual secretions that lead to secondary infection and obtain a cleaner surgical area. When flushing the eye of the affected limb, the flushing pressure is very important. If the flushing pressure is too low, it may be difficult to flush out the foreign matter in the eye. When the flushing pressure is too high, it is difficult to judge whether it has caused damage to the patient's eyes.

[0003] The eye irrigation devices of the prior art often have the following problems:

[0004] 1. The diameter of the eye washing device currently in use is small, and the flow rate of the eyewash liquid flowing out of the tube is small. The pressure is usually difficult to meet the needs of washing the eyes, and the washing efficiency is low.

[0005] 2. Most of the flushing devices currently in use are disposable products, causing great waste.

[0006] 3. The flushing pressure is difficult to control. Utility Model Content

[0007] In view of the above situation, in order to make up for the shortcomings of the prior art, the purpose of the utility model is to provide an eye flushing device, which adopts a liquid flow tube with a larger diameter, so that more flushing liquid can fill the liquid flow tube at the same time, bringing a greater flushing pressure; the outer surface of the liquid flow tube is arranged with a scale, and when using the device, the scale on the outer surface of the liquid flow tube is observed, and the medical staff accurately grasps the distance between the eye position and the flushing liquid bottle, and by adjusting the height of the flushing liquid bottle, the flushing liquid has greater kinetic energy when flowing from the bottle to the flushing part, thereby obtaining a greater flushing pressure; the flushing hose and the liquid flow tube are connected by a thread, and the flushing liquid hose can be removed from the liquid flow tube. The flushing hose can be replaced when flushing different patients to avoid cross infection, and the liquid flow tube can be recycled to save medical costs.

[0008] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0009] An eye flushing device comprises a medicine needle sheath, a medicine needle, a dropper, a liquid flow tube, a flow regulator, a flushing hose, and a hose protective cover, wherein the medicine needle sheath is sleeved on the medicine needle, the medicine needle is located at the head end of the liquid flow tube, the dropper is located at the lower end of the medicine needle, the flow regulator is located at the middle and lower part of the liquid flow tube, the flushing hose is connected to the end of the liquid flow tube, and the hose protective cover is installed at the head end of the flushing hose; the inner diameter of the medicine needle is increased to facilitate more flushing liquid to flow into the liquid flow tube at the same time; the inner diameter of the liquid flow tube is enlarged, and scales are covered on the outer surface of the liquid flow tube, and the end of the liquid flow tube is designed with threads; the flow regulator is installed in the middle and lower part of the liquid flow tube to adjust the inner diameter of the liquid flow tube and control the flow; the flushing hose comprises a flushing tube head cover, an internal thread, and a flushing hose, and a hook is designed at one end of the hose protective cover.

[0010] Furthermore, the inner diameter of the medicine needle increases, and the tip penetrates into the flushing liquid bottle. At the same time, the amount of flushing liquid entering the liquid flow tube through the medicine needle increases, and the kinetic energy increases, so the flushing pressure of the flushing liquid finally ejected through the liquid flow tube is large.

[0011] Furthermore, the inner diameter of the liquid flow tube is also enlarged, the lumen of the liquid flow tube is thicker, and more flushing liquid can be accommodated, so the pressure in the lumen increases.

[0012] Furthermore, the outer surface of the liquid flow tube is fully scaled. When the device is used, the height of the flushing liquid bottle from the patient's eyes can be determined by observing the scale with the naked eye. The height of the flushing liquid bottle is different, and the potential energy of the flushing liquid in the bottle is also different. The higher the flushing liquid bottle is, the greater the potential energy is, and the greater the kinetic energy of the flushing liquid when it flows out along the liquid flow tube. Finally, the pressure of the flushing liquid ejected through the flushing hose is also greater. Medical personnel adjust the height of the flushing liquid bottle and the flushing pressure by observing the scale on the outer surface of the liquid flow tube, but at the same time, the height of the flushing bottle should not be too high to avoid damage to the patient's eyes caused by excessive flushing pressure.

[0013] Furthermore, the end of the liquid flow tube is designed with a thread, and a detachable connection between the flushing hose and the liquid flow tube is achieved through a threaded connection.

[0014] Furthermore, the flow regulator is installed on the liquid flow tube. After the eye is basically cleaned, if it is necessary to reduce the flushing pressure, the flow regulator is adjusted to control the flushing liquid flow rate. When the flow rate is reduced, the flushing pressure is also reduced.

[0015] Furthermore, the flushing hose includes a flushing tube head cover, an internal thread, and a flushing hose; the internal thread is designed inside the flushing tube head cover, and the flushing tube head cover is connected to the liquid flow tube by means of the internal thread, and the flushing hose and the liquid flow tube are detachably connected.

[0016] Furthermore, the flushing hose is designed to be shorter in length, so when cleaning the eyes of different patients, the flushing hose can be replaced to avoid cross infection, and the liquid flow tube can be recycled again, effectively saving medical resources, reducing waste, and alleviating the economic burden on patients.

[0017] Furthermore, the hose protective cover is installed at the head end of the flushing hose to prevent external bacteria from entering the flushing hose; the hose protective cover is removed before use, and the flushing liquid flushes out from the flushing hose to flush the patient's eyes. At the end of flushing, the hose protective cover is connected to the flushing hose, and a hook is designed at the head end of the hose protective cover. The flushing hose is hung on the liquid flow tube above the dropper using the hook, which is convenient for placing the flushing hose after use.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The eye flushing device designed by the utility model increases the diameter of the liquid flow pipe, can accommodate more flushing liquid, and the flushing pressure increases when the flushing liquid is ejected along the flushing hose, ensuring that the flushing liquid can flush away foreign matter in the eye.

[0020] The height difference between the flushing liquid bottle and the patient's eyes determines the flushing pressure of the flushing liquid in the liquid flow tube. The outer surface of the liquid flow tube is designed with a scale. By observing the scale, medical staff can intuitively grasp the height difference between the flushing liquid bottle and the eye. By adjusting the height of the flushing liquid bottle, the flushing liquid obtains greater potential energy. When the flushing liquid flows out of the bottle to the flushing area, the potential energy is converted into more kinetic energy. The flushing liquid finally has a greater flushing pressure when it is ejected through the flushing hose.

[0021] A flow regulator is installed on the liquid flow tube. After the eyes are basically cleaned, if the flushing pressure needs to be reduced, the flow regulator is adjusted to limit the flushing liquid flow. When the flow is reduced, the flushing pressure is also reduced, avoiding damage to the patient's eyes caused by excessive flushing pressure for a long time.

[0022] The flushing hose and the liquid flow tube are connected by a detachable threaded connection. The flushing liquid hose can be removed from the liquid flow tube. The flushing hose can be replaced when flushing the eyes of different patients to avoid cross infection caused by multiple patients using the same flushing hose. The liquid flow tube can be recycled, saving medical resources and reducing the economic burden on patients.

[0023] A hose protective cover is designed at the head end of the flushing hose to isolate the flushing hose from the external environment, preventing bacteria from the external environment from entering the flushing hose before flushing. A hook is designed at the head end of the hose protective cover. After flushing, the flushing hose can be hung on the liquid flow pipe above the dropper using the hook.

[0031] In order to more clearly illustrate the technical solution of the embodiment of the utility model, the utility model will be clearly and detailedly described in conjunction with the accompanying drawings.

[0032] Example 1

[0033] Figure 1 FIG. 1 is an overall schematic diagram of the eye washing device according to an embodiment of the utility model, as shown in FIG. Figure 1 As shown, the eye flushing device includes a medicine needle sheath 1, a medicine needle 2, a dropper 3, a liquid flow tube 4, a flow regulator 6, a flushing hose 8, and a hose protective cover 9. The medicine needle sheath 1 is sleeved on the medicine needle 2, the medicine needle 2 is located at the head end of the liquid flow tube 4, the dropper 3 is located at the lower end of the medicine needle 2, the flow regulator 6 is installed on the liquid flow tube 4, the flushing hose 8 is connected to the end of the liquid flow tube 4, and the hose protective cover 9 is installed at the head end of the flushing hose 8.

[0034] In this embodiment, the medicine needle sheath 1 is sleeved on the medicine needle 2 to protect the medicine needle 2.

[0035] In this embodiment, the medicine needle sheath 1 is removed from the medicine needle 2 before use, the inner diameter of the medicine needle 2 is increased, and the tip is inserted into the flushing liquid bottle, so that more flushing liquid can pass through the medicine needle 2 and enter the liquid flow tube 4 at the same time. The flow rate increases, and the flushing pressure of the flushing liquid finally ejected through the flushing hose increases.

[0036] In this embodiment, the dropper 3 is arranged at the lower end of the medicine needle 2, and the flushing liquid enters the dropper 3 through the medicine needle. The dropper 3 is observed to grasp the flow rate and flow velocity of the flushing liquid.

[0037] In this embodiment, the diameter of the liquid flow tube 4 is increased, and the lumen of the liquid flow tube 4 becomes thicker, so that more flushing liquid can be accommodated, and the flushing liquid pressure in the lumen is increased. When flushing the patient's eyes, the pressure is sufficient to avoid low pressure and failure to clean foreign matter in the patient's eyes.

[0038] In this embodiment, the flow regulator 6 is installed on the liquid flow tube 4. After the cleaning of the eyes is basically completed, if it is necessary to reduce the flushing pressure, the flow regulator 6 is adjusted to control the flushing liquid flow rate. When the flow rate is reduced, the flushing pressure is also reduced. At the same time, if the patient feels uncomfortable during the flushing process, the flushing liquid flow rate can also be reduced by adjusting the flow regulator 6 to achieve the purpose of reducing the flushing pressure.

[0039] Example 2

[0040] like Figure 2 As shown, the outer surface of the liquid flow tube 4 is arranged with full scale 5, and the medical staff observes the scale 5 to accurately grasp the height difference between the flushing liquid bottle and the patient's eyes.

[0041] In this embodiment, the potential energy of the flushing liquid in the bottle is different when the flushing liquid bottle is placed at different heights. The higher the flushing liquid bottle is, the greater the potential energy is, and the greater the kinetic energy of the flushing liquid when it flows out along the liquid flow tube 4. Finally, the kinetic energy of the flushing liquid ejected through the flushing hose is converted into pressure energy, and the flushing pressure increases.

[0042] In this embodiment, medical personnel adjust the height of the flushing liquid bottle by observing the scale on the outer surface of the liquid flow tube to adjust the appropriate flushing pressure, but at the same time the height of the flushing bottle should not be too high to avoid damage to the patient's eyes due to excessive flushing pressure.

[0043] Example 3

[0044] like Figure 3-5 As shown, the liquid flow pipe 4 and the flushing hose 8 are detachably connected by means of threads.

[0045] In this embodiment, Figure 4 As shown, the end of the liquid flow tube 4 is designed with an external thread 401, such as Figure 5 As shown, the flushing hose includes a flushing tube head cover 7, an internal thread 701, and a flushing hose 8; the internal thread 701 is designed inside the flushing tube head cover 7, and the flushing tube head cover 7 is connected to the liquid flow tube 4 by means of the internal thread 701, thereby achieving the purpose of detachable connection between the flushing hose 8 and the liquid flow tube 2.

[0046] In this embodiment, the flushing hose 8 is relatively short, which saves medical resources. When cleaning the eyes of different patients, the flushing hose 8 needs to be replaced to avoid cross infection. The liquid flow tube 4 can be recycled multiple times, which effectively saves medical resources, reduces waste, and reduces the economic burden on patients.

[0047] In this embodiment, Figure 5 As shown, a hose protective cover 9 is designed at the head end of the flushing hose 8, and the hose protective cover 9 prevents external bacteria and the like from entering the flushing hose 8. The hose protective cover 9 is removed from the flushing hose 8 before use.

[0048] In this embodiment, a hook 901 is designed on the hose protective cover 9. After flushing is completed, the hose protective cover 9 is used to connect the flushing hose 8. The flushing hose 8 can be hung on the liquid flow tube 4 above the dropper 3 by means of the hook 901, so that the flushing hose 8 can be placed on the liquid flow tube more conveniently, avoiding the inconvenience caused by the flushing hose 8 being placed randomly.

[0049] In summary, the utility model increases the diameter of the liquid flow tube and the medicine needle tube, can accommodate more flushing liquid, and the flushing pressure increases when the flushing liquid is ejected along the flushing hose, ensuring that there is sufficient pressure to flush out foreign objects in the eyes; observe the scale on the outer surface of the liquid flow tube to adjust the height difference of the flushing liquid bottle relative to the eye, obtain the most suitable flushing pressure, avoid too little pressure to clean out foreign objects in the patient's eyes, and avoid too much pressure to cause damage to the patient's eyes, and the flushing pressure is simple to adjust; a flow regulator is installed on the liquid flow tube, after the eye is basically cleaned, if it is necessary to reduce the flushing pressure, the flow regulator is adjusted to limit the flushing liquid flow, and the flushing pressure is reduced when the flow is reduced, avoiding long-term flushing excessive pressure to cause damage to the patient's eyes; a detachable threaded connection is adopted between the flushing hose and the liquid flow tube, the flushing liquid hose can be removed from the liquid flow tube, and the liquid flow tube can be recycled, and it is only necessary to replace the flushing hose with a smaller length to clean the eyes of different patients, saving medical resources and reducing the economic burden on patients. A hose protective cover is designed to protect the flushing hose to prevent bacteria from entering the flushing hose. At the same time, a hook is designed on the upper end of the hose protective cover to facilitate hanging the flushing hose on the liquid flow tube to prevent the hose from being placed randomly and making treatment inconvenient.
