Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a multifunctional drainage bag. Background Technology
[0002] After a puncture or surgery, a drainage tube is often placed at the puncture site or stoma to drain the accumulated fluid. A drainage bag is then connected to the external end of the drainage tube to collect the fluid. The drainage bag has an inlet at the top and an outlet at the bottom, and the drainage tube is directly inserted into the inlet at the top of the drainage bag.
[0003] During use, the following significant defects were found in the existing drainage bags used in clinical practice:
[0004] 1. Poor interface compatibility: Traditional drainage bags are only equipped with standard Luer connectors, which cannot be adapted to the special spiral interface of central venous catheters (CVCs), resulting in the need for additional adapters, increasing the risk of infection and operational complexity.
[0005] 2. Large measurement error of residual fluid: When the drainage fluid volume is small, the fluid is easy to remain in the drainage tube and cannot flow into the bag, forcing medical staff to separate the tube for manual measurement. This process leads to: large measurement error, increased risk of secondary contamination and damage to the integrity of the closed drainage system.
[0006] 3. The loops on the drainage bag are inconvenient to hang on the hospital bed.
[0007] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content
[0008] The main objective of this invention is to provide a multifunctional drainage bag that improves the interface compatibility of the drainage bag and facilitates measurement and sampling when the drainage fluid is relatively small.
[0009] To achieve the above objectives, the solution of this utility model is:
[0010] A multifunctional drainage bag includes a bag body and an input tube connected to the top of the bag body; the input tube is made of transparent TPU material; a threaded connector is provided at the top of the input tube, and a standard Luer connector is detachably connected to the threaded connector; a first scale along the length direction is provided on the outer wall of the input tube; a flow regulating valve is provided at the lower part of the input tube; a self-sealing sampling port is provided on the side wall of the input tube above the flow regulating valve.
[0011] Furthermore, the threaded connector is of M6×0.75 specification; a cap is provided on the outside of the standard Luer connector.
[0012] Furthermore, a one-way anti-backflow valve is provided inside the input pipe below the threaded connector.
[0013] Furthermore, the input pipe is also equipped with a one-way air intake valve, and a detachable sealing cap is connected to the outside of the one-way air intake valve.
[0014] Furthermore, the self-sealing sampling port has a silicone diaphragm for repeated punctures, and a threaded protective cap is connected to the outside of the silicone diaphragm.
[0015] Furthermore, the threaded protective cover is connected to the side wall of the input pipe via a connecting rope.
[0016] Furthermore, the top of the bag is provided with a hanging ear, and a hook clip is connected to the hanging ear. The hook clip has a clamp body and a hook body connected to the clamp body, and the hook body is connected to the hanging ear.
[0017] Furthermore, the bag body is provided with a second scale, and the bottom of the bag body is provided with a discharge port that can be closed or opened.
[0018] Furthermore, the flow regulating valve has a housing and a roller, the input pipe passes through the housing, the housing is provided with an inclined groove, and the rotating shafts at both ends of the roller are located in the inclined groove, so as to change the flow rate of liquid in the input pipe by adjusting the position of the roller in the inclined groove.
[0019] With the above structure, the multifunctional drainage bag of this utility model has at least the following beneficial effects:
[0020] 1. By setting a threaded connector at the upper end of the inlet tube and connecting a standard Luer connector outside the threaded connector, a dual-connection device can be achieved: it can be compatible with abdominal drainage tubes and CVC catheters without the need for an adapter.
[0021] Second, when the drainage fluid volume is small, the drainage fluid can be measured through the first scale of the inlet tube, without having to drain the drainage fluid first and then use a measuring instrument to measure it. This makes the operation more convenient and helps to reduce measurement errors.
[0022] Third, the drainage fluid is extracted by needle puncture through the self-sealing sampling port. After use, the self-sealing sampling port automatically closes, and the sampling process is completely closed, saving medical consumables; a single sampling can avoid the waste of the drainage bag and shorten the operation time.
[0023] Fourth, the bag can be easily hung on the hospital bed using ear loops and hook clips.
[0024] Compared with the prior art, this utility model improves the connector at the upper end of the input tube to achieve compatibility with abdominal drainage tubes and CVC catheters, and can measure through the first scale on the outer wall of the input tube when the drainage fluid is small, thus achieving in-situ measurement: without the need to separate the pipeline, maintaining the system's closedness.

Detailed Implementation
[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0032] like Figures 1 to 4 As shown, this is a multifunctional drainage bag according to the present invention, including a bag body 1 and an input tube 2 connected to the top of the bag body 1; the input tube 2 is made of transparent TPU material; a threaded connector 21 is provided at the top of the input tube 2, and a standard Luer connector 22 is detachably connected to the threaded connector 21; a first scale 24 along the length direction is provided on the outer wall of the input tube 2; a flow regulating valve 25 is provided at the lower part of the input tube 2; a self-sealing sampling port 26 is provided on the side wall of the input tube 2 above the flow regulating valve 25. Preferably, the threaded connector 21 is of M6×0.75 specification; a cap 23 is provided on the outer side of the standard Luer connector 22.
[0033] Thus, the multifunctional drainage bag involved in this utility model achieves dual-use functionality by setting a threaded connector 21 at the upper end of the input tube 2 and connecting a standard Luer connector 22 to the outside of the threaded connector 21: it can be compatible with both abdominal drainage tubes and CVC catheters without the need for an adapter.
[0034] Preferably, a one-way anti-backflow valve 27 is provided in the input pipe 2 below the threaded connector 21. This ensures that the liquid entering the input pipe 2 through the Luer connector or threaded connector 21 can only flow downwards in one direction, preventing backflow and infection. When the drainage volume is small, the drainage volume can be measured through the first scale 24 of the input pipe 2, eliminating the need to drain the drainage volume before measuring with a measuring instrument, making operation more convenient and reducing measurement errors.
[0035] Preferably, the input pipe 2 is further provided with a one-way air inlet valve 28, and a detachable sealing cap 281 is connected to the outside of the one-way air inlet valve 28. When liquid accumulates on the input pipe 2 and cannot flow down into the bag body 1, the one-way air inlet valve 28 can be opened to change the negative pressure balance and allow the liquid to flow into the bag body 1.
[0036] Preferably, the self-sealing sampling port 26 has a silicone diaphragm 261 for repeated punctures, and a threaded protective cap 262 is connected to the outside of the silicone diaphragm 261. After puncture and extraction of drainage fluid through the self-sealing sampling port 26, the port automatically closes, ensuring a completely enclosed sampling process and saving medical consumables; single sampling avoids the waste of the drainage bag and shortens the operation time. Furthermore, the threaded protective cap 262 is connected to the side wall of the input tube 2 via a connecting rope.
[0037] Preferably, the top of the bag body 1 is provided with a hanging ear 12, and a hook clip 13 is connected to the hanging ear 12. The hook clip 13 has a clamping body 131 and a hook body 132 connected to the clamping body 131, and the hook body 132 is connected to the hanging ear 12. The hanging ear 12 and the hook clip 13 facilitate the hanging of the bag body 1 on the hospital bed.
[0038] The bag body 1 is provided with a second scale 11, and the bottom of the bag body 1 is provided with a drain outlet 14 that can be closed or opened. The second scale 11 measures the volume of drainage fluid entering the bag body 1. After the drainage fluid reaches a certain amount, family members or caregivers can open the drain outlet 14 to drain the drainage fluid.
[0039] Preferably, the flow regulating valve 25 has a housing 251 and a roller 253. The input pipe 2 passes through the housing 251, and the housing 251 is provided with a sloping groove 252. The rotating shafts at both ends of the roller 253 are located in the sloping groove 252, so as to change the flow rate of liquid in the input pipe 2 by adjusting the position of the roller 253 in the sloping groove 252. By pushing the roller 253 downward, the roller 253 compresses the input pipe 2, closing it, which facilitates the collection and measurement of drainage fluid through the input pipe 2. Alternatively, when it is necessary to pass through the self-sealing sampling port 26, the flow rate can be reduced, so that part of the drainage fluid accumulates at the sampling height of the self-sealing sampling port 26, which facilitates the extraction of drainage fluid.
[0040] Compared with the prior art, this utility model improves the connector part at the upper end of the input tube 2 to achieve compatibility with abdominal drainage tubes and CVC catheters (central venous catheters, which can be used for closed drainage treatment of pleural effusion), and can measure through the first scale 24 on the outer wall of the input tube 2 when the drainage fluid is small, realizing in-situ measurement: without the need to separate the tubing, maintaining the system's closure.
[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
