Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage bag flow rate regulating device. Background Art

[0002] Drainage bags are mostly used to drain out bleeding, fluid accumulation, etc. deep inside the body or in local surgery after surgery. Usually, a transparent plastic bag is connected to the end of the drainage tube to collect the drained fluid. At the same time, drainage bags can also be used for drainage of patients who are bedridden for a long time and have difficulty taking care of themselves, and even for special caregivers at home. The drainage speed can be controlled by the adjustment device on the outer wall of the drainage bag pipe.

[0003] For example, a drainage bag with controllable flow rate, with application number CN202122601532.9, includes a drainage bag and a speed regulating mechanism, the drainage bag has an inlet pipe and an outlet pipe, the speed regulating mechanism is assembled on the inlet pipe, the speed regulating mechanism includes a shell and an adjusting pressure wheel, the shell has a placement groove, both ends of the shell are provided with outlet holes matching the inlet pipe, the inlet pipe passes through the placement groove through the outlet hole, and guide grooves are provided on both sides of the shell; threaded rods are provided on both sides of the adjusting pressure wheel, the ends of the threaded rods pass through the guide grooves and are provided with locking nuts; wherein, the guide grooves are inclined; the drainage bag with controllable flow rate has a stable speed regulating function, and the flow rate is not prone to large changes after the speed regulation is completed. It is suitable for urine drainage, pericardial, thoracic and abdominal drainage, etc., and the drainage speed can be strictly controlled according to the patient's condition.

[0004] The above patent proposes that during the use of a drainage bag with controllable flow rate, when adjusting the flow rate of the drainage bag, the adjusting pressure wheel is rotated to determine the setting position of the adjusting pressure wheel, and then the threaded rod needs to be rotated to fix the setting position of the adjusting pressure wheel. Since the adjusting pressure wheel is slidingly set inside the mounting groove, and the threaded rod is threadedly connected to the two ends of the adjusting pressure wheel, such a setting requires the operator to manually fix the position of the adjusting pressure wheel when the threaded rod is threadedly connected to the adjusting pressure wheel, and then the threaded column can be rotated to fix the position, which is inconvenient to use.

[0005] Therefore, we propose a drainage bag flow rate regulating device to solve the above problems. Summary of the Invention

[0006] The purpose of the present utility model is to provide a drainage bag flow rate regulating device to solve the problem that the above-mentioned background technology proposes that when adjusting the flow rate of the drainage bag, after determining the setting position of the adjusting wheel by rotating the adjusting wheel, it is necessary to rotate the threaded rod to fix the setting position of the adjusting wheel. Since the adjusting wheel is slidingly set inside the mounting groove, and the threaded rod is threadedly connected to the two ends of the adjusting wheel, such a setting results in the operator needing to manually fix the position of the adjusting wheel when the threaded rod is threadedly connected to the adjusting wheel before rotating the threaded column to fix the position, which is inconvenient to use.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a drainage bag flow rate regulating device, comprising a drainage bag and a drainage pipe arranged in the middle of the lower end of the drainage bag, an adjusting component movably mounted on the outer surface of the drainage pipe, and positioning components movably embedded on both sides of the upper end of the adjusting component, the adjusting component is used to regulate and control the flow rate of the liquid in the drainage pipe, and the positioning component is used to fix the adjustment position of the adjusting component;

[0008] The positioning assembly includes a hollow frame and a connecting mechanism fixedly installed at the lower end of the hollow frame. The connecting mechanism is set to be embedded and fixed with the inner wall of the adjustment assembly, and the hollow frame is set to drive the connecting mechanism to move and adjust the setting position.

[0009] Preferably, the adjustment assembly includes a shell and a guide groove provided in the middle of the upper end of the shell, and an adjustment pressure wheel is movably installed in the inner cavity of the guide groove.

[0010] Preferably, a sliding groove is opened in the middle of the inner wall of both sides of the guide groove near the upper end, a limiting groove is opened in the middle of the lower end of the inner wall of the sliding groove, a through groove is opened in the middle of the upper end of the inner wall of the sliding groove, and circular clamping grooves are opened at the upper and lower ends of the inner wall of both sides of the through groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the operator needs to adjust the flow rate of the drainage bag, the operator pulls up the hollow frame so that the semicircular cards on both sides of the outer wall of the vertical plate are driven by the elastic force of the elastic element to pop out from the circular card groove at the lower end of the inner wall of the through groove, so that the fixed plate drives the soft rubber pad to rise, so that the soft rubber pad is released from the pressure fixation on the disc. At this time, the operator adjusts the flow rate of the liquid in the drainage pipe by rolling the setting position of the roller. After determining the setting position of the roller, the operator presses the hollow frame again to drive the vertical plate to descend, so that the dynamic vertical plate drives the semicircular cards to be re-embedded in the circular card groove at the lower end of the inner wall of the through groove under the elastic force of the elastic element, thereby completing the fixation of the roller setting position, which is convenient to use.

[0016] 2. The operator controls the flow rate of the liquid in the drainage pipe by adjusting the setting position of the rolling roller. When the roller slides, it is guided by the position of the disc rolling in the limit groove and the through groove cavity, thereby improving the stability of the roller sliding position.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-5 A drainage bag flow rate adjustment device includes a drainage bag 1 and a drainage pipe 2 arranged in the middle of the lower end of the drainage bag 1. An adjustment component 3 is movably installed on the outer surface of the drainage pipe 2. Positioning components 4 are movably embedded on both sides of the upper end of the adjustment component 3. The adjustment component 3 is used to adjust and control the flow rate of the liquid in the drainage pipe 2, and the positioning component 4 is used to fix the adjustment position of the adjustment component 3.

[0025] The positioning component 4 includes a hollow frame 41 and a connecting mechanism 42 fixedly installed at the lower end of the hollow frame 41. The connecting mechanism 42 is configured to be embedded and fixed with the inner wall of the adjustment component 3, and the hollow frame 41 is configured to drive the connecting mechanism 42 to move and adjust the setting position.

[0026] The connecting mechanism 42 includes a fixing plate 421 and a soft rubber pad 422 fixedly mounted on the lower end of the fixing plate 421 . The soft rubber pad 422 is used to increase the friction between the fixing plate 421 and the disc 333 .

[0027] A plurality of vertical plates 423 are fixedly installed at the upper end of the fixed plate 421 at linear and equal intervals. Elastic elements 424 are fixedly installed in the middle of both sides of the outer wall of the vertical plate 423. A semicircular locking ball 425 is fixedly installed at one end of the elastic element 424. The positioning component 4 is movably installed at the upper end of the inner cavity of the through groove 323, and the elastic element 424 drives the semicircular locking ball 425 to be movably embedded in the inner cavity of the circular locking groove 324.

[0028] In this embodiment, when the operator needs to adjust the flow rate of the drainage bag 1, the hollow frame 41 is pulled upward, so that the semicircular balls 425 on both sides of the outer wall of the vertical plate 423 are driven by the elastic force of the elastic element 424 to pop out from the circular groove 324 at the lower end of the inner wall of the through groove 323. As the vertical plate 423 rises, the semicircular balls 425 are stuck in the circular groove 324 at the upper end of the inner wall of the through groove 323 under the elastic force of the elastic element 424 and are fixed, thereby causing the fixing plate 421 to drive the soft rubber pad 422 to rise, so that the soft rubber pad 422 is separated from the pressure-fixed disk 333. The operator then adjusts the flow rate of the liquid in the drainage pipe 2 by rolling the roller 331 to determine the setting position of the roller 331. After determining the setting position of the roller 331, the operator presses the hollow frame 41 again to drive the vertical plate 423 to descend, so that the movable vertical plate 423 drives the semicircular clamping ball 425 to be re-embedded into the circular clamping groove 324 at the lower end of the inner wall of the through groove 323 under the elastic force of the elastic element 424, and then the fixing plate 421 drives the soft rubber pad 422 to press and fix the upper end of the disc 333 in the inner cavity of the limiting groove 322, thereby completing the fixation of the setting position of the roller 331, which is convenient to use.

[0029] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 3 The adjustment component 3 includes a shell 31 and a guide groove 32 opened in the middle of the upper end of the shell 31, and an adjustment pressure wheel 33 is movably installed in the inner cavity of the guide groove 32.

[0030] A sliding groove 321 is provided in the middle of both sides of the inner wall of the guide groove 32 near the upper end, a limiting groove 322 is provided in the middle of the lower end of the inner wall of the sliding groove 321, a through groove 323 is provided in the middle of the upper end of the inner wall of the sliding groove 321, and circular clamping grooves 324 are respectively provided at the upper and lower ends of both sides of the inner wall of the through groove 323. The adjusting pressure wheel 33 includes a roller 331 and a long shaft 332 fixedly installed in the middle of both ends of the roller 331, a disc 333 is fixedly installed in the middle of the outer surface of the long shaft 332, the disc 333 is movably installed in the inner cavity of the limiting groove 322 and the through groove 323, and the long shaft 332 is movably installed in the inner cavity of the sliding groove 321.

[0031] In this embodiment: the operator controls the flow rate of the liquid in the drainage pipe 2 by rolling the setting position of the roller 331. When the roller 331 slides, it is guided by the position of the disc 333 rolling in the limiting groove 322 and the inner cavity of the through groove 323, thereby improving the stability of the sliding position of the roller 331.

[0032] Working principle: When the operator needs to adjust the flow rate of the drainage bag 1, he first pulls the hollow frame 41 upwards, so that the hollow frame 41 drives the vertical plate 423 to rise together, and then the semicircular cards 425 on both sides of the outer wall of the vertical plate 423 are driven by the elastic force of the elastic element 424 to pop out from the circular card groove 324 at the lower end of the inner wall of the through groove 323. As the vertical plate 423 rises, the semicircular cards 425 are snapped into the circular card groove 324 at the upper end of the inner wall of the through groove 323 under the elastic force of the elastic element 424 and fixed, thereby causing the fixing plate 421 to drive the soft rubber pad 422 to rise, so that the soft rubber pad 4 22 is released from the pressing fixation of the disc 333. At this time, the operator controls the flow rate of the liquid in the drainage pipe 2 by rolling the setting position of the roller 331. After determining the setting position of the roller 331, the operator presses the movable vertical plate 423 of the hollow frame 41 to descend again, so that the movable vertical plate 423 drives the semicircular card ball 425 to be re-engaged in the circular card groove 324 at the lower end of the inner wall of the through groove 323 under the elastic force of the elastic element 424, so that the fixing plate 421 drives the soft rubber pad 422 to press and fix the upper end of the disc 333 in the inner cavity of the limiting groove 322, thereby completing the fixation of the setting position of the roller 331.
