Description

Technical Field

[0001] This utility model relates to the field of eyewash stations, and more specifically, to a disposable eyewash station structure. Background Technology

[0002] Most existing medical eyewash stations adopt an integrated fixed structure, and the flow rate adjustment function is generally lacking or relies on external valves, which has the following drawbacks: First, the integrated pipeline cannot achieve the adjustment of the flushing flow rate. During operation, one hand must hold the flushing head and the other hand must adjust the valve, which increases the burden on medical staff. Second, the fixed flow rate design is difficult to adapt to the different eye sensitivities of patients. Too large a flow rate can easily cause irritation or damage, while too small a flow rate will affect the flushing effect. Third, external adjustment components require additional sealing structures, which increases the risk of leakage and takes up space. Especially in disposable eyewash stations, the complex structure will significantly increase the production cost.

[0003] How to invent a disposable eyewash station structure to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a disposable eyewash station structure, which aims to improve the problems of existing medical eyewash stations, which are mostly one-piece fixed structures, lack flow regulation function or rely on external valves, resulting in inconvenient operation, inability to adapt to different patients' eye sensitivity, leakage risk and high production cost.

[0005] This utility model is implemented as follows: A disposable eyewash station structure includes a receiving plate, with a mounting hole through the center of the upper surface of the receiving plate. A liquid-passing ring is provided in the mounting hole, and a liquid-passing hole is coaxially provided in the center of the upper surface of the liquid-passing ring. A flushing tube is rotatably engaged on the liquid-passing ring. The flushing tube includes a liquid outlet tube and a liquid inlet tube coaxially arranged. A gap is provided at opposite ends of the liquid outlet tube and the liquid inlet tube, and the gap width is consistent with the thickness of the liquid-passing ring. An arc-shaped slider is integrally provided between the opposite surfaces of the liquid outlet tube and the liquid inlet tube. A coaxially distributed arc-shaped sliding groove is provided through the outer side of the upper surface of the liquid-passing ring. The arc-shaped slider is slidably connected in the arc-shaped sliding groove. A flow adjustment mechanism that can cooperate with each other is provided inside the liquid-passing ring and the liquid outlet tube.

[0006] In a preferred embodiment of this utility model, the flow regulating mechanism includes a fan-shaped liquid blocking plate integrally disposed on the inner wall of one side of the liquid passage hole and a flow regulating plate integrally disposed between the inner walls of the liquid outlet pipe. The surface of the flow regulating plate is provided with a fan-shaped liquid passage hole.

[0007] In a preferred embodiment of this utility model, sealing protrusions are coaxially arranged on the upper and lower surfaces of the liquid passage ring at the edges of the liquid passage holes. The outer diameter of each sealing protrusion is consistent with the inner diameter of the liquid outlet pipe and the liquid inlet pipe and extends into the liquid outlet pipe and the liquid inlet pipe respectively. A sealing rubber ring is provided on the end face of each sealing protrusion.

[0008] In a preferred embodiment of this utility model, the liquid outlet pipe and the liquid inlet pipe are detachably connected to protective caps, and the two ends of the abutment plate are provided with storage structures for the protective caps.

[0009] In a preferred embodiment of this utility model, the storage structure includes a three-pronged storage structure disposed at both ends of the abutment plate, wherein the width between the two prongs in each three-pronged storage structure corresponds to the inner and outer diameters of the protective cover opening.

[0010] In a preferred embodiment of this utility model, a limiting round head is integrally provided at the end of the middle rod of each of the three-pronged storage structures, and the diameter of the limiting round head is consistent with the inner diameter of the protective cover.

[0011] In a preferred embodiment of this utility model, each of the protective covers has an integrally formed snap ring on its inner wall, the liquid outlet pipe and the liquid inlet pipe have a first snap groove corresponding to the snap ring on their outer walls, and the three-pronged storage structure has a second snap groove corresponding to the snap ring on both sides of its outer walls.

[0012] In a preferred embodiment of this utility model, one end of a bottle mouth clamping rod is fixedly connected to both sides of the mounting hole on the bottom surface of the abutment plate. The two bottle mouth clamping rods are arranged opposite each other, and the other end of each rod is integrally provided with an arc-shaped clamping part corresponding to the structure of the saline bottle mouth.

[0013] The beneficial effects of this utility model are as follows: The disposable eyewash station structure obtained by the above design integrates the flow regulation function into the rotation of the rinsing tube through the rotating snap-fit ​​structure between the rinsing tube and the abutment plate. No additional valves or complex components are required; stepless flow regulation can be achieved simply by relative rotation. During operation, angle adjustment and flow control can be completed with one hand, improving the efficiency of medical staff. At the same time, precise flow area control allows for flexible adjustment of the water flow according to the patient's needs, avoiding the irritation or inefficiency problems of traditional fixed flow rates. Furthermore, the sealing design of the rotating connection reduces the risk of leakage. The structure is simple and compact, suitable for the low-cost mass production needs of disposable products, and improves the safety and convenience of eyewash operation. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution: a disposable eyewash station structure, including a connecting plate 1, with a mounting hole through the middle of the upper surface of the connecting plate 1, a liquid-passing ring 104 provided in the mounting hole, a liquid-passing hole 106 coaxially provided in the middle of the upper surface of the liquid-passing ring 104, a flushing tube 2 rotatably connected to the liquid-passing ring 104, the flushing tube 2 including a liquid outlet tube 201 and a liquid inlet tube 202 coaxially arranged, a gap is provided at one end of the liquid outlet tube 201 and the liquid inlet tube 202, and the gap width is the same as the thickness of the liquid-passing ring 104, an arc-shaped slider 203 is integrally provided between the surfaces of the opposite ends of the liquid outlet tube 201 and the liquid inlet tube 202, an arc-shaped sliding groove 105 coaxially distributed through the outer side of the upper surface of the liquid-passing ring 104, the arc-shaped slider 203 is slidably connected in the arc-shaped sliding groove 105, and a flow adjustment mechanism that can cooperate with each other is provided inside the liquid-passing ring 104 and the liquid outlet tube 201.

[0025] Please see Figures 4 to 7 The flow regulation mechanism includes a fan-shaped liquid blocking plate 107 integrally disposed on the inner wall of one side of the liquid passage 106 and a flow regulation plate 205 integrally disposed between the inner walls of the liquid outlet pipe 201. The surface of the flow regulation plate 205 is provided with a fan-shaped liquid passage 206.

[0026] A fan-shaped liquid-blocking plate 107 is provided on one inner wall of the liquid passage 106, and a flow regulating plate 205 is provided on the inner wall of the liquid outlet pipe 201, with a fan-shaped liquid passage 206 on the plate. When the flushing pipe 2 rotates, the relative position of the fan-shaped liquid passage 206 and the fan-shaped liquid-blocking plate 107 changes. The overlapping area of ​​the two determines the flow area of ​​the liquid passage 106. When they completely overlap, the liquid passage 106 is closed. Reverse rotation reduces the overlapping area, thereby increasing the flow area, thus achieving stepless flow regulation. This mechanism uses a simple fan-shaped structure combined with rotational action to accurately control the flow rate without complex components, meeting the cost and ease-of-use requirements of disposable products.

[0027] Furthermore, sealing protrusions 108 are coaxially arranged on the upper and lower surfaces of the liquid passage ring 104 at the edges of both ends of the liquid passage hole 106. The outer diameter of each sealing protrusion 108 is consistent with the inner diameter of the liquid outlet pipe 201 and the liquid inlet pipe 202, and extends into the liquid outlet pipe 201 and the liquid inlet pipe 202, respectively. A sealing rubber ring is provided on the end face of each sealing protrusion 108.

[0028] Sealing protrusions 108 are provided at both ends of the liquid passage holes 106 on the upper and lower surfaces of the liquid passage ring 104. The outer diameter of the protrusions 108 is the same as the inner diameter of the liquid outlet pipe 201 and the liquid inlet pipe 202 and extends into the pipe. A sealing rubber ring is provided on the end face of the protrusion. The sealing protrusion 108 fills the gap from the inside and forms a double seal with the sealing rubber ring to prevent the liquid from overflowing. The elastic damping of the sealing rubber ring can prevent the flushing pipe 2 from rotating randomly due to accidental contact, thereby improving the stability and controllability during operation.

[0029] Please see Figures 1 to 4 The outlet pipe 201 and the inlet pipe 202 are detachably connected to a protective cover 3, and the two ends of the abutment plate 1 are provided with a storage structure for the protective cover 3.

[0030] The outlet tube 201 and inlet tube 202 are detachably connected to protective caps 3, and storage structures are provided at both ends of the abutment plate 1. Before use, the protective caps 3 seal the tube openings through the snap-fit ​​structure to prevent dust or microbial contamination; when in use, the protective caps 3 can be removed and stored at both ends of the abutment plate 1 to avoid being carelessly discarded and causing contamination or loss, and to facilitate postoperative cleanup, in accordance with hygiene standards for medical settings.

[0031] Furthermore, the storage structure includes a three-pronged storage structure 101 disposed at both ends of the abutment plate 1, wherein the width between the two prongs in each three-pronged storage structure 101 corresponds to the inner and outer diameters of the opening of the protective cover 3.

[0032] The abutment plate 1 has a three-pronged storage structure 101 at both ends. The width of the two prongs corresponds to the inner and outer diameters of the opening of the protective cover 3, which can hold the edge of the protective cover 3. The removed protective cover 3 can be vertically inserted into the gap between the prongs of the three-pronged structure and fixed by mechanical locking, avoiding contact between the protective cover 3 and non-sterile surfaces. At the same time, centralized storage facilitates counting and cleaning, improving the standardization and efficiency of operating room operations.

[0033] Furthermore, each of the three-pronged storage structures 101 has an integrally provided limiting round head 102 at the end of the middle rod, and the diameter of the limiting round head 102 is consistent with the inner diameter of the protective cover 3.

[0034] The three-pronged storage structure 101 has a limiting round head 102 at the end of the middle rod, the diameter of which is the same as the inner diameter of the protective cover 3. When the protective cover 3 is inserted into the three-pronged structure, the limiting round head 102 is embedded inside the protective cover 3, forming a radial limit. Together with the locking action of the fork, the protective cover 3 is fixed from both the top and bottom and radial directions, ensuring a stable storage state. It is especially suitable for preventing the protective cover 3 from slipping off in moving or transportation scenarios.

[0035] Furthermore, each protective cover 3 has an integrally formed snap ring on its inner wall, and the outer walls of the liquid outlet pipe 201 and the liquid inlet pipe 202 are provided with a first snap groove 204 corresponding to the snap ring. The outer walls of both sides of the middle rod of the three-pronged storage structure 101 are provided with a second snap groove 103 corresponding to the snap ring.

[0036] The inner wall of the protective cover 3 is provided with a snap-fit ​​ring, and the outer walls of the liquid outlet pipe 201 and the liquid inlet pipe 202 are provided with a first snap-fit ​​groove 204. The two sides of the three-pronged storage structure 101 are provided with a second snap-fit ​​groove 103. During installation, the snap-fit ​​ring is snapped into the first snap-fit ​​groove 204 to fix the protective cover 3 at the pipe opening. After removal, the snap-fit ​​ring can be embedded into the second snap-fit ​​groove 103 to fix it to the storage structure. The same snap-fit ​​structure realizes dual functions, simplifies component design, and ensures the reliability of connection and the convenience of disassembly.

[0037] Furthermore, one end of the bottle mouth clamp 4 is fixedly connected to both sides of the mounting hole on the bottom surface of the abutment plate 1. The two bottle mouth clamps 4 are arranged opposite each other, and the other end of each is integrally provided with an arc-shaped clamping part corresponding to the structure of the saline bottle mouth.

[0038] Bottle neck clamping rods 4 are provided on both sides of the mounting hole at the bottom of the abutment plate 1, and an arc-shaped clamping part corresponding to the mouth of the saline bottle is provided at the other end of the rod. In use, the two bottle neck clamping rods 4 clamp the mouth of the saline bottle from the outside, and the arc-shaped clamping part conforms to the contour of the bottle mouth. The clamping force is generated through elastic deformation. Combined with the fixing effect of the liquid inlet tube 202 inserted into the bottle mouth, a double fixing structure is formed to ensure the stability of the device during rinsing and to avoid leakage of medicine or fluctuation of flow rate due to shaking of the bottle.

[0039] Working principle: Remove the two protective caps 3, pierce the sharp end of the inlet pipe 202 and insert it into the mouth of the saline bottle. The bottle mouth clamp 4 clamps the bottle mouth from the outside and fixes it. After the protective caps 3 are removed, they are stored in the three-pronged storage structure 101 at both ends of the abutment plate 1. Rotate the flushing pipe 2, and the arc-shaped slider 203 slides in the arc-shaped groove 105 of the liquid ring 104, so that the fan-shaped liquid outlet 206 of the flow regulating plate 205 and the fan-shaped liquid blocking plate 107 rotate relative to each other, changing the flow area of ​​the liquid outlet 106 to regulate the flow rate. The medicine flows in through the inlet pipe 202, enters the outlet pipe 201 through the overlapping area of ​​the liquid outlet 106 and the fan-shaped liquid outlet 206, and is sprayed out from the outlet pipe 201 to flush the eye. The sealing ring 108 and the sealing rubber ring ensure the connection is sealed. The whole thing is discarded after use.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
