Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a drainage device for pediatric intravenous liquid. Background Art

[0002] In current medical practice, intravenous infusion is a common and important means of pediatric treatment. However, unlike adults, children's medication dosage usually needs to be accurately calculated based on their weight, which makes the configuration of pediatric intravenous fluids relatively complicated. At present, the mainstream intravenous fluid dosages on the market are mostly designed for adults. Therefore, when intravenous fluids need to be configured for children, medical staff usually need to manually re-draw and configure, which is not only time-consuming and labor-intensive, but also slow in preparation.

[0003] The existing patent (application number: CN202122200117.2) proposes a special device for bedside configuration of intravenous antibiotic infusion, including a bottle body, a first separation diaphragm and a second separation diaphragm are arranged inside the bottle body, and a traction bottle cap is arranged at the bottom of the bottle body. The inside of the bottle body is divided into an upper medicine liquid grid, a Chinese medicine liquid grid, and a lower medicine liquid grid by the first separation diaphragm and the second separation diaphragm. Although the device can complete the mixing of different drugs, it cannot help medical staff complete the metering ratio of children's infusion during use. In the subsequent work process, the staff still needs to perform manual operation, which is not only time-consuming and labor-intensive, but also slow in liquid preparation.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a pediatric intravenous liquid configuration and discharge device to achieve the effect of automatically and quickly completing the metering and proportioning of pediatric infusion.

[0006] In order to solve the above technical problems, the present invention provides a pediatric intravenous liquid dispensing and drainage device, comprising:

[0007] A base plate, a control panel fixedly mounted on the top surface of the base plate;

[0008] A liquid taking component for measuring and taking liquid from an infusion bag;

[0009] The liquid taking assembly includes a support column arranged on the top surface of the base plate, a liquid taking bucket fixedly installed on one side of the support column, a movable moving rod installed inside the liquid taking bucket, a connecting plate fixedly connected above the moving rod, a first pointer fixedly connected to one side of the connecting plate, a metering plate fixedly installed on the top surface of the support column, a second motor installed above the base plate, a rotatable driving gear connected below the second motor, a threaded rod fixedly connected to the bottom surface of the connecting plate, a threaded sleeve threadedly connected to the outer wall of the threaded rod, and a driven gear installed on the outer wall of the bottom end of the threaded sleeve.

[0010] Furthermore, it also includes a moving component, which includes a mounting column installed on the top surface of the base plate, a first motor installed on one side of the mounting column, a rotatable bidirectional screw installed on the other side of the mounting column, and a moving block threadedly connected to the outer wall of the bidirectional screw.

[0011] Furthermore, a limiting groove is provided on the top surface of the bottom plate, a loading plate is arranged on the top surface of the bottom plate, a moving wheel is fixedly mounted on the bottom end of the loading plate, and the moving wheel is movably located inside the limiting groove.

[0012] Furthermore, the threaded sleeve is rotatably mounted on the top surface of the loading plate, the support column is fixedly mounted on the top surface of the loading plate, the driving gear is also rotatably mounted on the top surface of the loading plate, and the driving gear is meshed with the driven gear.

[0013] Furthermore, a cavity is provided inside the metering plate, the first pointer is movably located inside the cavity, a meter is provided on the outer wall of the metering plate, and the first pointer points to the lowest end of the scale in an initial state.

[0014] Furthermore, a movable second pointer is installed inside the cavity, and a retaining screw is integrally formed at the rear end of the second pointer. A pressing plate is threadedly connected to the outer wall of the retaining screw, and a rotatable connecting plate is connected to one side of the pressing plate. A resistance spring is fixedly connected to one side of the connecting plate, and a resistance plate is fixedly connected to the other end of the resistance spring.

[0015] Furthermore, a column is fixedly installed in the middle position of the top surface of the bottom plate, a liquid collecting pot is fixedly installed at the front end of the column, a liquid collecting pipe is fixedly installed on the top surface of the liquid collecting pot, and a dust cover is hinged on the top end of the liquid collecting pipe.

[0016] Furthermore, the number of the mounting columns is two, the bidirectional screw rod is rotatably installed between the two mounting columns, a round rod is fixedly installed on one side of the mounting column, the moving block is threadedly connected to the outer wall of the bidirectional screw rod and can also be slidably mounted on the outer wall of the round rod, and one side of the moving block is fixedly connected to the loading plate.

[0017] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0018] 1.

[0019] 2. In the present invention, after the liquid is taken, the first motor can be started through the control panel. After the first motor is started, it will drive the bidirectional screw to rotate. During the rotation of the bidirectional screw, the moving block threadedly connected to the outer wall of the bidirectional screw will be pushed. The moving block is fixedly connected to the loading plate, so the loading plate will move synchronously. Because the liquid taking bucket is above the loading plate, it will move synchronously with the loading plate. Therefore, after the first motor is turned, the liquid taking bucket will move toward the middle position of the device. After the liquid taking bucket moves to the top of the liquid collecting pipe, the second motor can be controlled to reverse through the control panel, so that the liquid in the liquid taking bucket is pushed out again and enters the liquid collecting pot through the liquid collecting pipe. At this time, the infusion bottle can be placed in the pit at the bottom of the liquid collecting pot to collect the measured liquid. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figures 1 to 7As shown, the present invention provides a drainage device for pediatric intravenous fluid configuration.

[0037] Specifically, by Figure 1-7 Given, including:

[0038] A base plate 1, and a control panel 2 fixedly mounted on the top surface of the base plate 1;

[0039] A liquid taking component for measuring and taking liquid from an infusion bag;

[0040] The liquid taking component includes a support column 19 arranged on the top surface of the base plate 1, a liquid taking bucket 13 fixedly installed on one side of the support column 19, a movable moving rod 14 installed inside the liquid taking bucket 13, a connecting plate 15 fixedly connected above the moving rod 14, a first pointer 202 fixedly connected to one side of the connecting plate 15, a metering plate 20 fixedly installed on the top surface of the support column 19, a second motor 21 installed above the base plate 1, a rotatable driving gear 22 connected below the second motor 21, a threaded rod 16 fixedly connected to the bottom surface of the connecting plate 15, a threaded sleeve 17 threadedly connected to the outer wall of the threaded rod 16, and a driven gear 18 installed on the outer wall of the bottom end of the threaded sleeve 17.

[0041] In the present invention, the contact plate 205 is pulled to adjust the second pointer 203 to the position required for measurement. After the adjustment is completed, the infusion bag is inserted into the bottom of the liquid collection bucket 13, and then the second motor 21 is started through the control panel 2 electrically connected to the second motor 21 and the first motor 8. After the second motor 21 is started, it will drive the driving gear 22 to rotate, and the driven gear 18 meshing with the driving gear 22 will start to rotate synchronously, and the driven gear 18 will drive the threaded sleeve 17 to rotate. After the threaded sleeve 17 rotates, the threaded rod 16 threadedly connected to the threaded sleeve 17 will be driven to rise due to the push of the thread, thereby driving the connecting plate 15 and The moving rod 14 moves upward, and the upward movement of the moving rod 14 will drive the rubber sheet 25 to move upward inside the liquid collection barrel 13. During the upward movement of the rubber sheet 25, the liquid inside the infusion bag will be drawn into the liquid collection barrel 13, thereby completing the liquid collection work. During the upward movement of the connecting plate 15, the first pointer 202 will be driven to move upward synchronously. The part of the first pointer 202 outside the metering plate 20 will always be aligned with the scale on the outer wall of the metering plate 20, so that the user can observe the amount of liquid taken in real time, making the liquid collection more accurate. The second pointer 203, which is also inside the metering plate 20, can prevent the device from taking excessive liquid.

[0042] In addition, by setting the guide rod 26, the connecting plate 15 is limited by the guide rod 26 during the movement and cannot move in other directions. The guide rod 26 is fixedly installed on the top surface of the support column 19, and the bottom end of the moving rod 14 is fixedly connected with a rubber sheet 25.

[0043] Furthermore, as a specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids in children.

[0044] Specifically, Figure 1-5 As shown, it also includes a moving component, which includes a mounting column 7 installed on the top surface of the base plate 1, a first motor 8 installed on one side of the mounting column 7, a rotatable bidirectional screw rod 9 installed on the other side of the mounting column 7, and a moving block 11 threadedly connected to the outer wall of the bidirectional screw rod 9.

[0045] In the present invention, the first motor 8 can be started through the control panel 2. After the first motor 8 is started, it will drive the bidirectional screw rod 9 to rotate. During the rotation of the bidirectional screw rod 9, the moving block 11 threadedly connected to the outer wall of the bidirectional screw rod 9 will be pushed. The moving block 11 is fixedly connected to the loading plate 12, so the loading plate 12 will move synchronously. Because the liquid collection barrel 13 is above the loading plate 12, it will move synchronously with the loading plate 12. Therefore, after the first motor 8 is turned, the liquid collection barrel 13 will move toward the middle position of the device. After the liquid collection barrel 13 moves to the top of the liquid collecting pipe 5, the second motor 21 can be controlled to reverse through the control panel 2, so that the liquid inside the liquid collection barrel 13 is pushed out again and enters the liquid collecting pot 4 through the liquid collecting pipe 5. At this time, the infusion bottle can be placed in the pit at the bottom of the liquid collecting pot 4 to collect the measured liquid.

[0046] In addition, since two liquid collection barrels 13 are provided, different liquids can be measured and poured into the liquid collecting pot 4 at the same time, and the measurement and mixing of the liquids can be completed directly, thereby improving the efficiency of the infusion preparation work.

[0047] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0048] Specifically, Figure 1-2 As shown, a limiting groove 23 is provided on the top surface of the bottom plate 1 , a loading plate 12 is arranged on the top surface of the bottom plate 1 , a moving wheel 24 is fixedly mounted on the bottom end of the loading plate 12 , and the moving wheel 24 is movably located inside the limiting groove 23 .

[0049] In the present invention, by providing the moving wheel 24, the movement of the loading plate 12 and the components installed above the loading plate 12 is smoother, and by arranging the moving wheel 24 in the limiting groove 23, the moving wheel 24 will not easily tilt during the movement, so that the loading plate 12 and the components installed above the loading plate 12 can be moved more stably.

[0050] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0051] Specifically, Figure 1-2As shown, the threaded sleeve 17 is rotatably mounted on the top surface of the loading plate 12 , the support column 19 is fixedly mounted on the top surface of the loading plate 12 , and the driving gear 22 is also rotatably mounted on the top surface of the loading plate 12 , and the driving gear 22 is meshed with the driven gear 18 .

[0052] In the present invention, by setting the driving gear 22 to mesh with the driven gear 18, the user can start the second motor 21 and the driving gear 22 can drive the driven gear 18 and the threaded sleeve 17 to start rotating. After the threaded sleeve 17 rotates, the thrust of the thread will push the threaded rod 16 upward, so that the threaded rod 16 drives the connecting plate 15 and the moving rod 14 to rise together, thereby realizing automatic liquid collection.

[0053] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0054] Specifically, Figure 7 As shown, a cavity 201 is provided inside the metering plate 20, and a first pointer 202 is movably located inside the cavity 201. A meter is provided on the outer wall of the metering plate 20, and the first pointer 202 points to the lowest end of the scale in an initial state.

[0055] In the present invention, by providing the first pointer 202 , the moving distance of the connecting plate 15 can be clearly recorded by the first pointer 202 , thereby allowing the user to complete the liquid collection more accurately.

[0056] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0057] Specifically, Figure 6-7 As shown, a movable second pointer 203 is also installed inside the cavity 201, and a retaining screw 206 is integrally formed at the rear end of the second pointer 203. A pressing plate 207 is threadedly connected to the outer wall of the retaining screw 206, and a rotatable connecting plate 208 is connected to one side of the pressing plate 207. A resistance spring 204 is fixedly connected to one side of the connecting plate 208, and a resistance plate 205 is fixedly connected to the other end of the resistance spring 204.

[0058] In the present invention, a pressing plate 207 is threadedly connected to the outer wall of the retaining screw 206, one side of the pressing plate 207 is connected to a rotatable connecting plate 208, one side of the connecting plate 208 is fixedly connected to a resistance spring 204, and the other end of the resistance spring 204 is fixedly connected to a resistance plate 205, so that the user can push the connecting plate 208 by rotating the pressing plate 207, thereby compressing the resistance spring 204, thereby increasing the resistance force of the resistance spring 204 on the resistance plate 205, so that the retaining screw 206 and the second pointer 203 can be fixed at a certain height of the metering plate 20 by the resistance plate 205, so that the user can adjust the second pointer 203 to the corresponding position in advance, so as to more clearly observe the amount of liquid taken, and also prevent the amount taken from exceeding the limit, thereby improving the accuracy of the device in taking liquid.

[0059] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0060] Specifically, Figure 1-4 As shown, a column 3 is fixedly installed in the middle position of the top surface of the base plate 1, a liquid collecting pot 4 is fixedly installed at the front end of the column 3, a liquid collecting pipe 5 is fixedly installed on the top surface of the liquid collecting pot 4, and a dust cover 6 is hinged on the top end of the liquid collecting pipe 5.

[0061] In the present invention, by providing a liquid collecting pipe 5 and a liquid collecting pot 4, the device can collect the liquid into the liquid collecting pot 4 through the liquid collecting pipe 5 after completing the liquid extraction, and process it in the subsequent process. By providing a dustproof cover 6, the liquid collecting pot 4 and the liquid collecting pipe 5 will not be easily contaminated by the outside world when not in use.

[0062] Furthermore, as another specific embodiment of the present invention, the present invention provides a drainage device for configuring intravenous fluids for children.

[0063] Specifically, Figure 1-4 As shown, there are two mounting columns 7, and the bidirectional screw rod 9 is rotatably installed between the two mounting columns 7. A round rod 10 is fixedly installed on one side of the mounting column 7. The moving block 11 is threadedly connected to the outer wall of the bidirectional screw rod 9 and can also be slidably mounted on the outer wall of the round rod 10. One side of the moving block 11 is fixedly connected to the loading plate 12.

[0064] In the present invention, the moving block 11 is threadedly connected to the outer wall of the bidirectional screw rod 9 and can also be slidably sleeved on the outer wall of the round rod 10, so that the moving block 11 is limited by the round rod 10 during movement, making the movement of the moving block 11 more stable.

[0065] Working principle: When in use, first measure the amount of infusion required according to the weight of the child, then pull the contact plate 205 to adjust the second pointer 203 to the position required for measurement, and after the adjustment is completed, insert the infusion bag into the bottom of the liquid collection bucket 13, and then start the second motor 21 through the control panel 2 electrically connected to the second motor 21 and the first motor 8. After the second motor 21 is started, it will drive the driving gear 22 to rotate, and the driven gear 18 meshing with the driving gear 22 will start to rotate synchronously, and the driven gear 18 will drive the threaded sleeve 17 to rotate. After the threaded sleeve 17 rotates, the threaded rod 16 threadedly connected to the threaded sleeve 17 will be driven due to the push of the thread. The upward movement of the moving rod 14 will drive the rubber sheet 25 to move upward inside the liquid collection barrel 13. During the upward movement of the rubber sheet 25, the liquid inside the infusion bag will be drawn into the liquid collection barrel 13, thereby completing the liquid collection work. During the upward movement of the connecting plate 15, the first pointer 202 will be driven to move upward synchronously. The part of the first pointer 202 outside the metering plate 20 will always be aligned with the scale on the outer wall of the metering plate 20, so that the user can observe the amount of liquid taken in real time, making the liquid collection more accurate. The second pointer 203, which is also inside the metering plate 20, can prevent the device from taking excessive liquid.

[0066] After the liquid is taken, the first motor 8 can be started through the control panel 2. After the first motor 8 is started, the bidirectional screw rod 9 will be driven to rotate. During the rotation of the bidirectional screw rod 9, the moving block 11 threadedly connected to the outer wall of the bidirectional screw rod 9 will be pushed. The moving block 11 is fixedly connected to the loading plate 12, so the loading plate 12 will move synchronously. Because the liquid taking barrel 13 is above the loading plate 12, it will move synchronously with the loading plate 12. Therefore, after the first motor 8 is turned, the liquid taking barrel 13 will move toward the middle position of the device. After the liquid taking barrel 13 moves to the top of the liquid collecting pipe 5, the second motor 21 can be controlled to reverse through the control panel 2, so that the liquid inside the liquid taking barrel 13 is pushed out again and enters the liquid collecting pot 4 through the liquid collecting pipe 5. At this time, the infusion bottle can be placed in the pit at the bottom of the liquid collecting pot 4 to collect the measured liquid.

[0067] In addition, since two liquid collection barrels 13 are provided, different liquids can be measured and poured into the liquid collecting pot 4 at the same time, and the measurement and mixing of the liquids can be completed directly, thereby improving the efficiency of the infusion preparation work.

[0068] By setting up a liquid collection component, the device can measure and collect liquid at the same time, and the liquid collection process imitates the conventional liquid collection method and will not easily damage the infusion part of the infusion bag, and will not cause excessive waste of resources. Most of the steps in the process are replaced by machinery, and there is no need for excessive manpower cooperation, which reduces labor costs and improves work efficiency.

[0069] By setting up a moving component, the device can take two different liquids at the same time and mix them in the subsequent process, so that the device can complete quantitative liquid taking and mix the two liquids through the device, and the whole process is completed by the mechanical structure, saving manpower.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
