Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically to a postoperative drainage fluid metering and pouring device. Background Technology
[0002] Drainage fluid measurement refers to the accurate measurement and recording of fluids drained from a patient's body (such as postoperative drainage). This is an important part of medical care, mainly used to assess patient recovery, monitor complications, and guide treatment. Common clinical methods for measuring drainage fluid include directly reading the value from graduated drainage bags or bottles, or using measuring cups or other instruments.
[0003] Currently, drainage pouring devices such as those published in patent application CN217321484U are still used in clinical practice. However, according to hospital infection control requirements, these devices and measuring cups need to be disinfected and cleaned after each use, which is cumbersome and increases the workload of nursing staff. If disposable medical dressing boxes made of the same material as disposable plastic cups are used for measurement, the thin and soft side walls of the dressing boxes make them prone to leakage of drainage fluid during pouring due to deformation of the box, further increasing the workload of nursing staff. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a postoperative drainage fluid metering and pouring device. By installing multiple disposable inner cups inside a rigid outer cup, it is convenient for medical staff to operate the outer cup to receive drainage fluid, reducing the difficulty of operation. Moreover, the inner cups can be directly discarded after use without cleaning and disinfection, which can also reduce the workload of medical staff, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a postoperative drainage fluid metering and pouring device, including an outer cup, a transparent plate embedded in one side wall of the outer cup, and scale lines processed on the surface of the transparent plate;
[0006] The outer cup is rotatably connected to an inner cup rotation mechanism. Multiple inner cups for holding drainage fluid are inserted inside the inner cup rotation mechanism. The inner cup rotation mechanism drives the inner cups to rotate inside the outer cup, so as to rotate one of the inner cups to the position of the transparent plate, so as to measure the volume of drainage fluid inside the inner cup through the scale lines on the surface of the transparent plate.
[0007] In a preferred embodiment, the inner cup rotating mechanism includes multiple inner cup seats, which are located below multiple inner cups respectively. An upper hollow column is fixed to the bottom of the inner cup seat, and a lower hollow column is sleeved on the bottom of the upper hollow column. A rotating plate is fixed to the bottom of the lower hollow column. A driving assembly for driving the rotating plate to rotate is provided inside the outer cup, and the inner cup is driven to rotate inside the outer cup through the rotating plate.
[0008] In a preferred embodiment, the top of the outer cup is threadedly connected to a cup lid for covering the inner cup, and the cup lid has an outlet on the side facing the transparent plate for the inner cup to pass through.
[0009] A spring is fixed between the upper hollow column and the lower hollow column. When the spring rotates the inner cup to the position of the transparent plate, it pushes the inner cup upward so that the top of the inner cup passes through the cup outlet.
[0010] In a preferred embodiment, the drive assembly includes a rotating shaft movably connected to the bottom of the inner side of the outer cup via a bearing. The rotating shaft passes through a rotating plate and is fixed to the rotating plate. A gear a is fixed to the outer end of the rotating shaft. A gear b meshes with one side of the gear a. The gear b passes through the side wall of the outer cup and extends out of one side of the outer cup.
[0011] In a preferred embodiment, a limiting plate is fixed at the top of the rotating shaft, and the limiting plate has a plurality of circular holes for the bottom end of the inner cup to pass through, the inner diameter of the circular holes being equal to the outer diameter of the inner cup.
[0012] In a preferred embodiment, an arc-shaped outer cup handle is fixed to one side of the outer cup.
[0013] In a preferred embodiment, a water outlet nozzle is fixed to one side of the top of the inner cup, and when it is inside the outer cup, the water outlet nozzle at the top of the inner cup faces the center of the outer cup.
[0014] In a preferred embodiment, the bottom of the outer cup on the side away from the transparent plate has a through hole for the gear b to extend out.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. By installing multiple disposable inner cups inside a rigid outer cup, medical staff can easily operate the outer cup to receive drainage fluid, reducing the difficulty of operation. Moreover, the inner cups can be directly discarded after use, eliminating the traditional cleaning and disinfection steps, and also reducing the workload of medical staff, achieving two benefits at once.
[0017] 2. By installing a lid on the top of the outer cup, the unused inner cup can be covered, preventing the drainage fluid from contaminating the unused inner cup and ensuring hygiene.
[0018] 3. By setting a rotating inner cup mechanism inside the outer cup, the inner cup can be driven to rotate inside the outer cup, and multiple inner cups can be rotated sequentially to the position of the transparent plate, so that medical staff can take turns adjusting the position of multiple inner cups, reducing the operational difficulty of this utility model.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Refer to the instruction manual appendix Figure 1 and 2This utility model provides a postoperative drainage fluid metering and pouring device, including an outer cup 1. An arc-shaped outer cup handle 2 is fixed on one side of the outer cup 1. The arc shape is more in line with the curve of the human hand, so that medical staff can easily hold the outer cup handle 2 for operation. Both the outer cup 1 and the outer cup handle 2 are made of hard plastic, so that the outer cup 1 and the outer cup handle 2 have a certain strength and hardness to prevent deformation, while making it easy for medical staff to operate and preventing easy leakage of drainage fluid.
[0031] The outer cup 1 is rotatably connected to an inner cup rotating mechanism 6, which houses multiple inner cups 5 for holding drainage fluid. Each inner cup 5 has a spout fixed to one side of its top. When inside the outer cup 1, the spout of the inner cup 5 faces the center of the outer cup 1; when in use, the spout faces outwards. During use, medical staff simply hold the outer cup handle 2 and align the spout of the inner cup 5 with the drainage fluid outlet tube to easily fill the inner cup 5 with the drainage fluid. The inner cups 5 can be made of the same material as disposable plastic cups, reducing usage costs. They can be discarded after each use, avoiding cross-infection from reuse and ensuring hygiene. This eliminates the need for traditional cleaning and disinfection steps, reducing the workload of medical staff.
[0032] To accurately measure the volume of the drainage fluid inside the inner cup 5 during use, a transparent plate 4 is embedded in one side wall of the outer cup 1. The surface of the transparent plate 4 is machined with graduations, the values of which increase from bottom to top and start from "0". The inner cup rotation mechanism 6 can drive the inner cup 5 to rotate inside the outer cup 1, specifically as follows... Figures 3-6 As shown, the inner cup rotation mechanism 6 includes multiple inner cup seats 61, each located below a multiple inner cup 5. An upper hollow column 62 is fixed to the bottom of each inner cup seat 61, and a lower hollow column 63 is fitted around the bottom of the upper hollow column 62. A rotating plate 65 is fixed to the bottom of the lower hollow column 63. A drive assembly 66 is provided inside the outer cup 1 to drive the rotating plate 65 to rotate. Before use, medical personnel need to drive the rotating plate 65, lower hollow column 63, upper hollow column 62, and inner cup seats 61 to rotate using the drive assembly 66. This causes the inner cup seats 61 to rotate the inner cups 5 within the outer cup 1 until one of the inner cups 5 is rotated to the position of the transparent plate 4, aligning the bottom of the inner cup 5 with the starting position of the scale line on the surface of the transparent plate 4. Medical personnel can read the volume of the drainage fluid contained inside the inner cup 5 through the scale line on the surface of the transparent plate 4 for recording purposes.
[0033] In this embodiment, the structure of the driving component 66 is as follows: Figure 6As shown: It includes a rotating shaft 661 that is movably connected to the bottom of the inner cup 1 via a bearing. A limiting plate 67 is fixed at the top of the rotating shaft 661. The limiting plate 67 has multiple circular holes for the bottom of the inner cup 5 to pass through. The inner diameter of the circular holes is equal to the outer diameter of the inner cup 5. The rotating shaft 661 passes through the rotating plate 65 and is fixed to the rotating plate 65. A gear a662 is fixed at the outer end of the rotating shaft 661. A gear b663 meshes with one side of the gear a662. The gear b663 passes through the side wall of the outer cup 1 and extends out of one side of the outer cup 1. A through hole for the gear b663 to extend out is opened at the bottom of the outer cup 1 on the side away from the transparent plate 4.
[0034] When it is necessary to rotate the inner cup 5, medical staff only need to rotate gear b663, which drives gear a662 that meshes with it to rotate. Gear a662 drives the rotating shaft 661 and the limiting plate 67 to rotate, and the inner cup 5 inserted inside them to rotate together, until one of the inner cups 5 is rotated to the position of the transparent plate 4.
[0035] Furthermore, in this invention, the diameter of gear a662 is larger than the diameter of gear b663. The transmission ratio of gear a662 and gear b663 is set according to the specific number of inner cups 5. Taking a number of inner cups 5 as an example: the transmission ratio of gear a662 to gear b663 corresponding to 6 inner cups 5 is 6:1. This setting can achieve the effect that for every rotation of gear b663, gear a662 rotates 60°. At this time, it is just possible to rotate gear b663 a full circle to rotate each inner cup 5 to the position facing the transparent plate 4 in turn, so as to facilitate the operation of medical staff.
[0036] Markings can also be made on gear b663 (for example, drawing short colored lines on the exposed surface of gear b663; other markings are also acceptable, and this utility model does not impose further limitations) to help medical staff determine whether gear b663 has been rotated a full circle.
[0037] Since inner cup 5 is a disposable consumable and is discarded after each use, it is important to prevent the drainage fluid from contaminating other inner cups 5 during use. Figures 1-3 As shown, a cup lid 3 for covering the inner cup 5 is threadedly connected to the top of the outer cup 1. The cup lid 3 has an outlet 68 on the side facing the transparent plate 4 for the inner cup 5 to pass through. A spring 64 is fixed between the upper hollow column 62 and the lower hollow column 63. Figure 4As shown, the bottom of the inner cup 5 located below the cup lid 3 will compress the spring 64. When the inner cup 5 rotates to the position of the transparent plate 4, since the top of the inner cup 5 at this position is not restricted, the compressed spring 64 will push the inner cup 5 upward, causing the top of the inner cup 5 to pass through the outlet 68. The water outlet tip of the inner cup 5, which just extends out of the outer cup 1, faces the center of the outer cup 1. Therefore, in order to facilitate the collection of drainage fluid, medical staff also need to manually adjust the position of the water outlet tip and rotate it to a position facing the outside of the outer cup 1 (e.g., Figure 1 and Figure 2 (As shown in the image) to serve as a container for receiving drainage fluid;
[0038] Moreover, the cup lid 3 is also made of hard plastic to ensure that it has a certain strength and hardness, so that it can cover the inner cup 5 located below the cup lid 3 from above, preventing the drainage liquid from contaminating other inner cups 5 and ensuring hygiene. At the same time, it can also squeeze the inner cup 5 and the spring 64 downward without deformation, thus meeting the usage requirements of this utility model.
[0039] In addition, it is worth noting that the limiting plate 67, inner cup seat 61, upper hollow column 62, lower hollow column 63, rotating plate 65, rotating shaft 661, gear a662 and gear b663 in this utility model can all be made of lightweight plastic in order to reduce the overall weight and facilitate operation by medical staff.
[0040] When the inner cup 5 in the outer cup 1 is used up, a new inner cup 5 can be replaced. Other structures can be reused to reduce the cost of using this utility model.
[0041] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
