Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically an adjustable quantitative drainage control device. Background Technology

[0002] In clinical medicine, drainage of pleural or peritoneal effusions is a common treatment used to relieve compression symptoms, improve respiratory function, or obtain diagnostic samples. However, achieving precise control of the drainage volume and rate during the drainage process is a key challenge in clinical practice.

[0003] Traditional drainage devices often rely on the experience of medical staff to manually adjust the negative pressure or intermittently clamp the drainage tube, which has the following drawbacks and potential risks:

[0004] 1) When the drainage rate or the volume of a single drainage exceeds the safe threshold, such as in the drainage of pleural effusion, it may cause serious complications such as re-expansion pulmonary edema, hypotension, and mediastinal shift; in the drainage of ascites, it may lead to hypotension, electrolyte disturbance (such as hypokalemia), kidney damage, and even induce hepatic encephalopathy (especially in patients with cirrhosis). The potential risks caused by negligence are great.

[0005] 2) Manual operation is subject to subjective errors and is difficult to manage in a standardized manner;

[0006] 3) Frequent manual monitoring and intervention are required, increasing the workload of medical staff.

[0007] While some existing technologies offer automated drainage devices, their functions are mostly limited to pressure monitoring or alarm prompts, lacking proactive closed-loop control capabilities. For example, conventional drainage bottles require manual estimation of drainage volume and manual shut-off of the tubing, making dynamic adjustment based on real-time drainage volume impossible. Some electric negative pressure devices, while allowing preset pressure parameters, lack integrated flow metering and automatic termination functions, and are structurally complex and costly. Furthermore, existing technologies struggle to achieve rapid and flexible threshold setting and execution to meet the personalized drainage needs of different patients' pathological conditions (such as children and those with cardiopulmonary insufficiency).

[0008] Therefore, there is an urgent need to develop an adjustable quantitative drainage control device. Utility Model Content

[0009] To overcome the problems existing in the prior art, the purpose of this utility model is to provide an adjustable quantitative drainage control device that monitors the drainage volume in real time through gravity and terminates the drainage by folding the flip-over stacking assembly based on gravity, thereby avoiding the risk of excessive drainage and improving operational safety and clinical efficiency; it adopts a purely mechanical structure, has low manufacturing and maintenance costs, and can be repeatedly sterilized and reused.

[0010] To achieve the above objectives, this utility model provides the following technical solution: an adjustable quantitative drainage control device, comprising a fixed plate, a flip-over stack assembly, an elastic element, a pull rod, and a hook;

[0011] The fixed plate is provided with a first sliding groove, the pull rod is disposed in the first sliding groove, and the pull rod moves along the first sliding groove; one end of the elastic element is connected to the fixed plate, the other end of the elastic element is connected to the top end of the pull rod, and the bottom end of the pull rod is connected to the hook;

[0012] The flip-over stack assembly includes a positioning block, a folding block, a connecting shaft, and a transmission component. The positioning block is connected to the fixed plate, and the top surfaces of the positioning block and the folding block are arranged opposite each other at an obtuse angle, and the top surfaces of the positioning block and the folding block are connected by the connecting shaft. A pull rod channel is provided at the bottom of the positioning block and the folding block, and the position of the pull rod channel corresponds to the position of the first slide groove. The transmission component is provided at the position corresponding to the pull rod channel on the connecting shaft. A drainage pipe channel is provided on the side wall of the positioning block and the folding block.

[0013] The transmission component is triggered by the pull rod to rotate the folding block, so that the folding block fits into the positioning block.

[0014] In actual use, the drainage bag is suspended on the hook, and the drainage tube on the drainage bag is installed in the drainage tube channel on the side wall of the positioning block and the folding block. In the initial state, the drainage tube is set at an obtuse angle, and the liquid can pass through freely; as the liquid in the drainage bag gradually increases, the drainage bag moves along the first slide groove due to gravity until the pull rod triggers the transmission component to rotate the folding block to fit against the positioning block. At this time, the drainage tube fixed to the side wall of the positioning block and the folding block is bent, realizing the closure of drainage.

[0015] The present invention is further configured such that: the fixing plate is provided with a positioning block mounting hole, and the positioning block is connected to the positioning block mounting hole by bolts;

[0016] The positioning block is rotatably connected to the connecting shaft, and the folding block and the transmission component are rigidly connected to the connecting shaft.

[0017] The present invention is further configured such that: a second sliding groove is provided on one side of the positioning block, and the bolt passes through the second sliding groove and the mounting hole of the positioning block to connect the positioning block and the fixing plate.

[0018] The present invention is further configured such that: the fixing plate is also provided with scale lines, and the end of the connecting shaft near the scale lines is provided with an indicator arrow.

[0019] When the bolt is loose, the flip-over stack assembly moves relative to the bolt through the second slide groove on the fixed block. After aligning the indicator arrow with the corresponding target scale line, the bolt is tightened to fix the positioning block to the fixed plate. At this time, the positioning block cannot move.

[0020] The present invention is further configured such that: a rack is provided on the pull rod, and the transmission component is a gear structure.

[0021] The gear and rack are matched in terms of parameters such as tooth pitch, tooth height, tooth profile, and module. When the pull rod moves to the gear, the rack on the pull rod meshes with the gear.

[0022] The transmission component can be configured as any transmission structure that cooperates with the pull rod. For example, the transmission component can be configured as a lever, and a wave block can be configured on the pull rod.

[0023] The present invention is further configured such that: the positioning block and the folding block are respectively equipped with magnets, and the magnetic poles of the magnets built into the positioning block are opposite to those of the magnets built into the folding block.

[0024] The purpose of setting up the magnet is to reduce the displacement required to trigger the flip-over stack assembly to fold and close, thereby reducing the change in the flow rate required for triggering and improving the trigger sensitivity of the device. That is, at the target flow rate, a small displacement or weight change can trigger the flip-over stack assembly to fold completely and accurately, achieving a reliable closing effect.

[0025] The present invention is further configured such that: the side wall of the positioning block is provided with a first drainage pipe channel parallel to the top surface of the positioning block, and the side wall of the folding block is provided with a second drainage pipe channel parallel to the top surface of the folding block.

[0026] The present invention is further configured such that: anti-reverse plates are provided inside the first drainage tube channel and the second drainage tube channel.

[0027] The purpose of the above structure is to prevent the drainage tubes installed in the first and second drainage tube channels from falling off.

[0028] The present invention is further provided with a hanging hole at the top of the fixing plate. The hanging hole facilitates the fixing and hanging of the adjustable quantitative drainage control device.

[0029] In summary, the beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0030] 1. This invention utilizes the gradually increasing gravity of the drainage bag to monitor the drainage volume in real time. Gravity drives a pull rod to move, triggering a transmission mechanism that rotates the folding block until it aligns with the positioning block. This causes the drainage tube, fixed to the side walls of the positioning and folding blocks, to bend, automatically closing the drainage and mitigating the risk of excessive drainage. It eliminates the need for frequent manual monitoring and intervention, reducing the workload of medical staff while avoiding errors from manual control, thus improving operational safety and clinical efficiency.

[0031] 2. The device of this utility model is a purely mechanical structure with a simple overall structure, low manufacturing and maintenance costs, and can be reused for disinfection; it is simple to use and less susceptible to interference; it is intuitive and easy to operate, and can achieve instant response and precise control of the drainage flow.

[0038] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this utility model, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the protection scope of this utility model. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the scope of this utility model.

[0039] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0040] like Figures 1-3 As shown, this is a preferred embodiment of the present invention, an adjustable quantitative drainage control device, including a fixed plate 1, a flip-over stacking block assembly, an elastic element 12, a pull rod 15 and a hook 13;

[0041] The fixing plate 1 is provided with a first sliding groove 3, and the pull rod 15 is disposed in the first sliding groove 13. The pull rod 15 moves along the first sliding groove 3. The elastic element 12 is a tension spring. One end of the tension spring is connected to the fixing plate 1 through a fixing screw 11, and the other end of the tension spring is connected to the top end of the pull rod 15. The bottom end of the pull rod 15 is connected to the hook 13. The top end of the fixing plate 1 is also provided with a hanging hole 2.

[0042] It should be noted that the maximum drainage capacity of clinically common drainage bags is 1000ml, and in most cases the density of the drainage fluid is estimated to be approximately equal to the density of water. The elastic element 12 is selected as a tension spring with a stiffness coefficient within this range that obeys Hooke's law.

[0043] Combination Figures 1-2 As shown, the flip-over stack assembly includes a positioning block 5, a folding block 6, a connecting shaft 7, and a transmission component. The positioning block 5 is connected to the fixing plate 1. The top surfaces of the positioning block 5 and the folding block 6 are arranged at an obtuse angle to each other, and the top surfaces of the positioning block 5 and the folding block 6 are connected by the connecting shaft 7. A pull rod channel is provided at the bottom of the positioning block 5 and the folding block 6. The position of the pull rod channel corresponds to the position of the first slide groove 3. The transmission component is provided at the corresponding position of the connecting shaft 7 and the pull rod channel. A drainage pipe channel is provided on the side wall of the positioning block 5 and the folding block 6.

[0044] Combination Figure 3 As shown, the pull rod 15 is provided with a rack 16, and the transmission component is a gear 9. When the pull rod 15 moves to the gear 9, the rack 16 on the pull rod 15 meshes with the gear 9, driving the folding block 6 to rotate so that the folding block 6 fits against the positioning block 5.

[0045] The fixing plate 1 is provided with a positioning block mounting hole 4, and the positioning block 5 is connected to the positioning block mounting hole 4 by bolts.

[0046] The positioning block 5 is rotatably connected to the connecting shaft, and the folding block and the transmission component are rigidly connected to the connecting shaft 7.

[0047] A second groove 8 is provided on one side of the positioning block 5, and the bolt passes through the second groove 8 and the positioning block mounting hole 4 to connect the positioning block 5 and the fixing plate 1.

[0048] The fixed plate 1 is also provided with a scale line 14, and the end of the connecting shaft 7 near the scale line 14 is provided with an indicator arrow 10.

[0049] When the bolt is loose, the flip-over stack assembly moves relative to the bolt through the second slide groove 8 on the fixing block 5. After aligning the indicator arrow 10 with the corresponding target scale line, the bolt is tightened to fix the positioning block 5 to the fixing plate 1. At this time, the positioning block 5 cannot move.

[0050] The side wall of the positioning block 5 is provided with a first drainage channel 17 parallel to the top surface of the positioning block 5, and the side wall of the folding block 6 is provided with a second drainage channel 18 parallel to the top surface of the folding block 6.

[0051] The first drainage tube channel 17 and the second drainage tube channel 18 are provided with anti-reverse plate 19.

[0052] The anti-reverse plate 19 is a thin plate structure that tilts inward to form a leaf. Its one-way anti-reverse mechanism makes it easy to insert the drainage tube and prevents the drainage tube from falling out after insertion.

[0053] The positioning block 5 and the folding block 6 each have a built-in magnet 20, and the magnetic poles of the magnet 20 built into the positioning block 5 are opposite to those of the magnet 20 built into the folding block 6.

[0054] In actual use, first suspend the fixing plate 1 next to the hospital bed, keeping it vertical. Then set the target drainage volume, and move the movable flipping block assembly up and down along the second slide 8 so that the indicator arrow 10 on the connecting shaft 7 is aligned with the target scale line. Tighten the bolts to fix the positioning block 5 to the fixing plate 1. At this time, the positioning block 5 cannot move; while the flipping block 6 is rigidly connected to the connecting shaft 7 and the gear 9.

[0055] After setting the target drainage volume, insert the drainage tube into the first drainage tube channel 17 and the second drainage tube channel 18 provided on the side wall of the positioning block 5 and the folding block 6. After inserting the drainage tube, leave a certain length of redundant drainage tube, place the drainage bag at the hook 13, and complete the installation of the equipment.

[0056] After the drainage bag is suspended on the hook 13, as the drainage volume increases, the tension spring is pulled down by the weight of the drainage bag, and the rack 16 is pulled down along the first slide groove 3. When the drainage volume approaches the target volume, the rack 3 contacts and meshes with the gear 9 on the connecting shaft 7 of the flipping block assembly. At this time, a further increase in drainage volume will drive the gear 9 to continue rotating, thereby driving the flipping block 6 to flip upward. Since both the positioning block 5 and the flipping block 6 have built-in magnets 20, only partial folding is needed to trigger the mutual attraction and adhesion of the magnets 20 on the positioning block 5 and the flipping block 6. At this time, the drainage tube fixed to the side of the rotating folding block is bent, realizing the closure of drainage.

[0057] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
