Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a quantitative pressing type iodophor plastic bottle. Background Art

[0002] In medical disinfection operations, iodophor is a commonly used disinfectant, and the design of its packaging container directly affects the use effect and safety. The following technical defects mainly exist in the current iodophor packaging on the market:

[0003] 1. Inaccurate dose control

[0004] Traditional extrusion plastic bottles discharge liquid by deforming the bottle body, and it is difficult for medical staff to control the single extrusion volume. Clinical data shows that the error of manually extruded liquid volume can reach ±0.3 mL (refer to "Technical Specification for Hospital Disinfection" WS / T 367-2022). Insufficient dose leads to incomplete disinfection, while excessive dose causes waste and increases the risk of skin irritation.

[0005] 2. High pollution risk

[0006] The open bottle mouth design is prone to contacting external pollutants during repeated use, and there is a lack of effective isolation measures for the liquid in the bottle. According to the statistics of "Measures for the Management of Hospital Infections", the pollution rate of traditional bottled disinfectants is as high as 28.7% after 3 days of use, and the lack of one-way valve leads to liquid backflow, further exacerbating the pollution.

[0007] 3. High maintenance cost

[0008] The integrated structure makes it difficult to clean, and the accumulation of residual liquid is prone to breeding bacteria. Medical institutions need to compulsorily replace the unused disinfectant every 7 days, resulting in about 15% of material waste.

[0009] The above technical defects seriously restrict the standardized use of iodophor in clinics, and there is an urgent need for a new type of packaging container that combines accurate quantification, anti-pollution, and easy operation. Summary of the Invention

[0011] For this reason, the first object of this application is to provide a quantitative pressing type iodophor plastic bottle. By setting a quantitative box and an accurate pressing transmission structure, accurate quantification of 10 ML of liquid discharged per press is achieved, avoiding the problems of waste of iodophor and improper use dose.

[0012] The second object of this application is to provide a quantitative pressing type iodophor plastic bottle. The design of the one-way valve at the top of the piston and the liquid outlet pipe effectively prevents liquid backflow, ensures the purity of the liquid in the bottle, and reduces the pollution risk.

[0013] The third object of the present application is to provide a quantitative pressing type povidone iodine plastic bottle. The pressing key is connected to the bottle body through a chute, and the design of the isolation box, sliding block and return spring in the connecting rod structure makes the pressing operation smoother and more stable, and it can automatically reset after pressing, improving the operation experience of the user.

[0014] To achieve the above object, the first aspect embodiment of the present application proposes a quantitative pressing type povidone iodine plastic bottle, including a bottle body, a quantitative box, a pressing key, a connecting rod structure, a liquid outlet pipe, a piston and a bottle cap. Among them, the bottle body is a hollow cavity structure for containing povidone iodine liquid; the quantitative box is connected to the top of the bottle body by a thread for realizing the quantitative outflow of the liquid; the pressing key is arranged on the side wall of the bottle body and can reciprocate relative to the bottle body; the connecting rod structure is arranged in the bottle body, one end is connected to the pressing key, and the other end is connected to the piston; the liquid outlet pipe is arranged in the bottle body, and the top end communicates with the quantitative box; the piston is arranged inside the liquid outlet pipe and can move up and down linearly along the inner wall of the liquid outlet pipe; the bottle cap is arranged on the top of the quantitative box and is detachably connected to the quantitative box; when pressing the pressing key, the pressing key drives the connecting rod structure to move, and then pushes the piston upward, so that the povidone iodine liquid in the bottle body flows into the quantitative box and flows out through the bottle cap, and the povidone iodine liquid flowing out each time is a fixed volume.

[0015] In the quantitative pressing type povidone iodine plastic bottle of the embodiment of the present application, the device is provided with a quantitative box and a precise pressing transmission structure, and 10 ML of liquid is discharged each time of pressing, avoiding waste and improper dosage.

When the pressing key is released, the return spring makes the pressing key reset.

[0018] In an embodiment of the present application, the pressing key is slidably connected to the side wall of the bottle body through a chute. The chute is arranged on the side wall of the bottle body, and the pressing key can make a reciprocating linear motion in the chute.

[0019] In an embodiment of the present application, a first one-way valve is arranged on the piston. The first one-way valve opens when the piston moves upward, allowing the active iodine liquid in the bottle body to enter the liquid outlet pipe, and closes when moving downward to prevent liquid backflow.

Detailed Description of the Embodiments

[0034] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0035] The following describes a quantitative pressing type active iodine plastic bottle according to an embodiment of the present application in conjunction with the drawings.

[0036] As shown Figures 1-5 in the figure, a quantitative pressing type povidone iodine plastic bottle according to an embodiment of the present application may include a bottle body 1, a quantitative box 2, a pressing key 3, a connecting rod structure 4, a liquid outlet pipe 5, a piston 6, and a bottle cap 7.

[0037] It can be understood that the bottle body 1, as a container for holding povidone iodine liquid, provides a storage basis for the entire device. When the user needs to take povidone iodine, the pressing key 3 will be operated. The pressing key 3 is arranged on the side wall of the bottle body 1 and can reciprocate along the side wall of the bottle body 1. When the pressing key 3 is pressed, the pressing key 3 starts to move. Since one end of the connecting rod structure 4 is connected to the pressing key 3 and the other end is connected to the piston 6, the movement of the pressing key 3 will drive the operation of the connecting rod structure 4. Under the driving action of the connecting rod structure 4, the piston 6 starts to move linearly upward along the inner wall of the liquid outlet pipe 5 inside the liquid outlet pipe 5. Because the piston 6 moves upward in the liquid outlet pipe 5, the pressure change in the bottle body 1 causes the povidone iodine liquid to flow into the liquid outlet pipe 5, and as the piston 6 continues to move upward, the liquid enters the quantitative box 2 through one end at the top of the liquid outlet pipe 5. The quantitative box 2 is connected to the top of the bottle body 1 by threads. This connection method is not only stable but also convenient for disassembly and cleaning operations when needed. After the liquid enters the quantitative box 2, it will be stored quantitatively. Finally, the povidone iodine liquid stored in the quantitative box 2 will flow out through the bottle cap 7 that is detachably connected to the top of the quantitative box 2. Each time it is pressed, under the synergistic action of the entire structure, the povidone iodine liquid flowing out is a fixed volume, thus realizing the function of accurate quantitative liquid discharge.

[0038] In an embodiment of the present application, as Figures 1-5 shown in the figure, the connecting rod structure 4 includes an isolation box 41, a vertical plate 42, a first connecting rod 43, a second connecting rod 44, a third connecting rod 45, a sliding block 46, and a return spring 47.

[0039] It can be understood that when the user presses the pressing key 3, the pressing key 3 starts to move linearly in the chute 8 on the side wall of the bottle body 1. Since one end of the first connecting rod 43 is fixedly connected to one end of the pressing key 3, the movement of the pressing key 3 will drive the first connecting rod 43 to move synchronously.

[0040] After the first connecting rod 43 moves, the second connecting rod 44 that is rotatably connected to the other end thereof also moves accordingly. The second connecting rod 44 is slidably arranged on the sliding block 46 fixed to the side wall of the vertical plate 42. This enables the second connecting rod 44, when moving, to rotate around the connection point with the first connecting rod 43 on the one hand and slide on the sliding block 46 on the other hand, thereby changing the movement direction and transmitting force. The vertical plate 42 is fixedly arranged on the isolation box 41. The isolation box 41 is located on the side of the bottle body 1 close to the pressing key 3, playing an isolation and protection role for the internal structure, and at the same time preventing the internal structure from contaminating the liquid.

[0041] As the second connecting rod 44 moves, the third connecting rod 45 rotatably connected to its other end is also driven. The other end of the third connecting rod 45 is connected to the bottom of the piston 6, and the third connecting rod 45 slides on the side wall of the isolation box 41. Driven by the second connecting rod 44, the third connecting rod 45 pushes the piston 6 to move upward in the liquid outlet pipe 5, thereby squeezing the active iodine liquid in the bottle body 1 into the liquid outlet pipe 5 and further entering the metering box 2 through relevant channels.

[0042] When the user releases the pressing key 3, the return spring 47 fixedly connected to the vertical plate 42 will exert an elastic force because its other end is fixedly connected to the pressing key 3, pulling the pressing key 3 back to its original position. The reset of the pressing key 3 drives the first connecting rod 43 to move in the reverse direction, and then through the transmission of the second connecting rod 44 and the third connecting rod 45 in sequence, the piston 6 moves downward in the liquid outlet pipe 5 and returns to its initial position, preparing for the next pressing and liquid discharging. The design of the entire connecting rod structure 4 ensures a stable and efficient transmission relationship between the pressing operation and the piston movement, enabling the device to operate smoothly.

[0043] In an embodiment of the present application, as Figures 1-5 shown, the pressing key 3 is slidably connected to the side wall of the bottle body 1 through a chute 8. The chute 8 is arranged on the side wall of the bottle body 1, and the pressing key 3 can perform reciprocating linear motion in the chute 8.

[0044] It can be understood that when the user needs to take the active iodine, an external force is applied to the pressing key 3. The pressing key 3 is installed on the side wall of the bottle body 1, and the side wall of the bottle body 1 is provided with a chute 8 adapted to it. The outer shape structure design of the pressing key 3 fits with the chute 8, enabling the pressing key 3 to slide stably in the chute 8.

[0045] When an external force acts on the pressing key 3, the pressing key 3 starts to perform linear motion in the chute 8. Due to the tight fit between the pressing key 3 and the chute 8, the direction of this linear motion can be accurately controlled and always remains on the linear track defined by the chute 8, thus realizing reciprocating linear motion. This stable and accurate motion mode ensures the reliability of the pressing operation.

[0046] In an embodiment of the present application, as Figures 1-5 shown, a first one-way valve 61 is provided on the piston 6. The first one-way valve 61 opens when the piston moves upward, allowing the active iodine liquid in the bottle body 1 to enter the liquid outlet pipe 5, and closes when moving downward to prevent liquid backflow. A second one-way valve 62 is provided at the top of the liquid outlet pipe 5 located in the metering box 2. The second one-way valve 62 opens when the piston moves upward to allow the liquid to enter the metering box 2 and closes when the liquid flows out of the metering box 2 to prevent liquid backflow.

[0047] It is understandable that when the user presses the pressing key 3, the pressing key 3 moves along the sliding groove 8, driving the linkage structure 4 to operate, and then pushing the piston 6 to move upward in the liquid outlet pipe 5. At this time, the first one-way valve 61 on the piston 6 is affected by the upward pressure difference. Due to the special design of the first one-way valve 61, when the piston 6 moves upward, this valve opens, and the active iodine liquid in the bottle body 1 smoothly enters the liquid outlet pipe 5 under the drive of the pressure difference. The liquid continuously flows upward in the liquid outlet pipe 5 until it reaches the top of the liquid outlet pipe 5 in the metering box 2.

[0048] When the liquid reaches the top of the liquid outlet pipe 5 in the metering box 2, due to the pressure generated by the continuous upward movement of the piston 6, the second one-way valve 62 is prompted to open, and the active iodine liquid can enter the metering box 2. At this time, the first one-way valve 61 always remains open to ensure that the liquid can continuously flow from the bottle body 1 to the metering box 2.

[0049] When the user releases the pressing key 3, the return spring 47 comes into play, pulling the pressing key 3 back to its original position, and the linkage structure 4 drives the piston 6 to move downward in the liquid outlet pipe 5. At this time, the first one-way valve 61 is affected by the reverse pressure difference and quickly closes. This closing action effectively prevents the active iodine liquid in the liquid outlet pipe 5 from flowing back to the bottle body 1, ensuring the purity of the liquid in the bottle body 1 and avoiding contamination caused by backflow.

[0050] During the downward movement of the piston 6, the liquid in the metering box 2 has a tendency to flow out of the metering box 2 due to gravity and pressure. At this time, the second one-way valve 62 closes under the pressure in the liquid outflow direction, preventing the liquid in the metering box 2 from flowing back into the liquid outlet pipe 5, ensuring that the liquid can only flow in the direction from the metering box 2 through the bottle cap 7, thus ensuring the accuracy of the liquid outflow volume per press and the stability of the liquid flow direction. Through the coordinated work of the first one-way valve 61 and the second one-way valve 62 at different stages, this device realizes the one-way, stable and accurate flow process of the active iodine liquid from the bottle body 1 through the liquid outlet pipe 5 to the metering box 2 and then out of the metering box 2.

[0051] In an embodiment of the present application, as Figures 1-5 shown, scale lines 21 are provided on the metering box 2 for displaying the volume of the active iodine liquid in the metering box 2.

[0052] It is understandable that the scale lines 21 are clearly marked on the outer surface of the metering box 2. The scale lines 21 are marked with scale values in sequence from the bottom to the top of the metering box 2, and the setting of the scale values is related to the liquid outflow volume per press.

[0053] In an embodiment of the present application, as Figures 1-5 shown, each time the pressing key 3 is pressed, the volume of the active iodine liquid flowing out is 10 ML.

[0054] It can be understood that during each pressing process, the distance that the piston 6 moves upward can make the volume of the active iodine liquid entering the metering box 2 exactly 10 ML. When the liquid in the metering box 2 reaches 10 ML, the user releases the pressing key 3. At this time, the return spring 47 comes into play. One end of the return spring 47 is fixedly connected to the vertical plate 42, and the other end is fixedly connected to the pressing key 3. The elastic force generated by it pulls the pressing key 3 to reset. The reset of the pressing key 3 drives the first connecting rod 43 to move in the reverse direction, and then through the transmission of the second connecting rod 44 and the third connecting rod 45 in sequence, the piston 6 moves downward in the liquid outlet pipe 5 and returns to the initial position. During the downward movement of the piston 6, the first one-way valve 61 closes to prevent the liquid from flowing back into the bottle body 1.

[0055] The 10 ML of active iodine liquid in the metering box 2 flows out through the channel communicating with the liquid outlet pipe 5 and through the bottle cap 7. The user can confirm that the amount of the flowing out liquid is 10 ML by observing the scale line 21 on the metering box 2. The scale line 21 marks the scale values upward from the bottom of the metering box 2, and the minimum scale division value is adapted to the 10 ML liquid outflow volume, which is convenient for the user to accurately judge. Through such a series of closely coordinated operation processes, the function of accurately flowing out 10 ML of active iodine liquid every time the pressing key 3 is pressed is realized.

[0056] It should be noted that after testing, 3 gauze blocks are used for skin disinfection each time, and the water content of each gauze block is about 10 ml. Pressing out 10 ML each time can accurately achieve the required amount of 10 ML and avoid waste.

[0057] Specifically, during the actual execution process, the user first holds the bottle body 1. When it is necessary to take active iodine for disinfection operations, an external force is applied to the pressing key 3. The pressing key 3 is installed in the sliding groove 8 on the side wall of the bottle body 1. Under the action of the external force, the pressing key 3 moves linearly along the sliding groove 8. Since one end of the first connecting rod 43 is fixedly connected to the pressing key 3, the movement of the pressing key 3 drives the first connecting rod 43 to move synchronously.

[0058] After the first connecting rod 43 moves, the second connecting rod 44 rotatably connected to it starts to act. The second connecting rod 44 is slidably arranged on the sliding block 46 fixed to the side wall of the vertical plate 42. The vertical plate 42 is fixed on the isolation box 41, and the isolation box 41 is located on one side of the bottle body 1 close to the pressing key 3. When the second connecting rod 44 moves, while rotating around the connection point with the first connecting rod 43, it slides on the sliding block 46, changes the movement direction and transmits the force, and then drives the third connecting rod 45 to move.

[0059] The other end of the third connecting rod 45 is connected to the bottom of the piston 6, and the third connecting rod 45 slides on the side wall of the isolation box 41. Driven by the second connecting rod 44, the third connecting rod 45 pushes the piston 6 to move upward in the liquid outlet pipe 5. When the piston 6 moves upward, the first one-way valve 61 on it opens, and the active iodine liquid in the bottle body 1 enters the liquid outlet pipe 5 under the action of the pressure difference. The liquid continuously flows upward in the liquid outlet pipe 5. When it reaches the top of the liquid outlet pipe 5 in the metering box 2, due to the pressure generated by the continuous upward movement of the piston 6, the second one-way valve 62 is prompted to open, and the active iodine liquid enters the metering box 2.

[0060] As the piston 6 continuously moves upward, when the volume of the active iodine liquid entering the metering box 2 reaches 10 ML, the user releases the pressing key 3. At this time, the return spring 47 fixedly connected to the vertical plate 42 exerts its elastic effect. Since the other end of it is fixedly connected to the pressing key 3, it pulls the pressing key 3 to return to its original position. The return of the pressing key 3 drives the first connecting rod 43 to move in the reverse direction, and then through the transmission of the second connecting rod 44 and the third connecting rod 45 in sequence, the piston 6 moves downward in the liquid outlet pipe 5 and returns to its initial position. During the downward movement of the piston 6, the first one-way valve 61 closes to prevent the liquid from flowing back to the bottle body 1.

[0061] The 10 ML of active iodine liquid in the metering box 2 flows out through the channel communicating with the liquid outlet pipe 5 and through the bottle cap 7 detachably connected to the top of the metering box 2. The user can confirm that the amount of the flowing-out liquid is 10 ML by observing the scale lines 21 marked with scale values from bottom to top on the metering box 2. The minimum scale division value of the scale lines 21 is adapted to the 10 ML liquid outflow volume, which is convenient for accurate judgment. Through such a series of operation processes with the close cooperation of various components, this quantitative pressing type active iodine plastic bottle realizes accurate quantitative liquid outflow and meets the actual use requirements of the medical scenario.

[0062] In summary, for a quantitative pressing type active iodine plastic bottle according to an embodiment of the present application, the device is provided with a metering box and a precise pressing transmission structure, and each pressing discharges 10 ML of liquid, avoiding waste and improper dosage. One-way valves are provided at the top of the piston and the liquid outlet pipe to prevent liquid backflow and ensure the purity of the liquid. The pressing key and the bottle body are connected through a sliding groove, and the connecting rod structure includes an isolation box, etc., with smooth pressing and automatic reset, improving the operation experience.
