Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a drainage fluid collection and metering device. Background Technology

[0002] Most deep tissue surgeries require the placement of a drainage device to drain postoperative fluid. This device consists of a drainage tube, a drainage bulb, or a drainage bag. For some major surgeries, the suction end of the drainage tube is placed inside the surgical cavity, while the outlet end is placed outside the body and connected to the drainage bulb or bag. By sealing the drainage bag or squeezing the drainage bulb, the principle of siphon or negative pressure suction is used to guide pus, exudate, blood, tissue fluid, or other fluids accumulated in the body tissue or body cavity to the outside, preventing fluid accumulation that could lead to postoperative infection.

[0003] Drainage bags, drainage buckets, and other drainage fluid containers usually have graduations marked with 100-1000ml on their outer walls to facilitate medical staff in observing the drainage volume. Due to structural limitations of the drainage fluid container, the intervals between the graduations on its outer wall are fixed, resulting in limited accuracy. When medical staff need to perform precise measurements, they must remove the drainage fluid and use a more accurate measuring device such as a measuring cup to measure the drainage volume. However, it should be noted that existing measuring cups come in various sizes, including 10, 20, 50, and 100 ml. Smaller measuring cups generally have higher accuracy. However, when medical staff transfer the drainage fluid from the container to the measuring cup, errors can easily occur. For example, if the estimated drainage volume in the container is about 20 ml, and a 20 ml measuring cup is used for measurement, but the drainage fluid in the cup is slightly more than 20 ml, then the medical staff will need to pour the 20 ml of drainage fluid into another measuring cup. This can lead to leakage or spillage, making the process cumbersome and reducing the safety of medical staff, while also lowering the accuracy of the drainage fluid measurement.

[0004] Therefore, how to set up a drainage fluid collection and metering device that can solve the above problems is a technical problem that needs to be solved. Utility Model Content

[0005] To address the aforementioned problems, the present invention aims to provide a drainage fluid collection and metering device that solves the issues of existing metering cups, such as low flexibility, lower accuracy with larger capacity, and the need for multiple replacements of smaller capacity metering cups based on drainage fluid volume, resulting in cumbersome operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: including a base, a drainage fluid recovery box movably disposed within the base, a connecting ramp fixed to one side of the base, a plurality of metering components passing through the base, and a test tube assembly detachably disposed on the connecting ramp and mating with the metering components;

[0007] The metering assembly consists of several metering boxes arranged in a gradually decreasing capacity; each metering box includes a box body, a sealing cover hinged to the top of the box body, a connecting pipe connected to the sealing cover, a drainage fluid overflow hole penetrating the side wall of the box body, a guide plate fixed to the outside of the drainage fluid overflow hole, a liquid inlet hole penetrating the other side wall of the box body corresponding to the adjacent drainage fluid overflow hole, a first liquid outlet pipe connected to the bottom of the box body, a first valve passing through the liquid outlet pipe, a second liquid outlet pipe connected to the bottom of the outer side wall of the box body, and a second valve passing through the liquid outlet pipe;

[0008] The test tube assembly includes several sample collection test tubes arranged in a row, a detachable connecting cap disposed at the inlet of several sample collection test tubes, a first drainage conduit with one end connected to a second outlet tube and the other end passing through a connecting cap and disposed inside a sample collection test tube, and a second drainage conduit connecting adjacent sample collection test tubes.

[0009] The base has an installation cavity, and the drainage fluid recovery box is slidably disposed in the installation cavity; the base has connecting grooves arranged to cooperate with the metering box, and the connecting grooves of the base also have through holes that communicate with the installation cavity on the first outlet pipe corresponding to the first outlet pipe.

[0010] Furthermore, the metering boxes include 500ml metering boxes, 200ml metering boxes, 100ml metering boxes, 50ml metering boxes, 20ml metering boxes, and 10ml metering boxes.

[0011] Furthermore, the drainage fluid recovery box includes a box body and a detachable box cover located at the opening of the box body; the box cover has an inlet hole corresponding to the position of the first outlet pipe.

[0012] Furthermore, both the measuring box and the sample collection tube can be equipped with capacity graduation lines.

[0013] Furthermore, the outer side of the connecting ramp is provided with several test tube limiting grooves that cooperate with the sample collection test tubes along its length.

[0014] This utility model has the following beneficial effects:

[0015] 1- This utility model features metering boxes arranged sequentially and connected in a manner with gradually decreasing capacity. This allows medical staff to set the number of metering boxes of each capacity based on the approximate volume of the drainage fluid in the container. On the one hand, the number of metering boxes of each capacity can be flexibly adjusted according to the approximate volume of the drainage fluid. On the other hand, it effectively avoids the problems of existing metering containers having limited capacity and requiring repeated replacement of measuring cups, which are cumbersome to operate, and the limited measurement accuracy of large-capacity measuring cups.

[0016] 2- This utility model features a sample collection tube connected to the measuring box. On the one hand, it facilitates medical staff to sample the drainage fluid into separate tubes, making it convenient for them to collect the drainage fluid for subsequent testing. On the other hand, the capacity of the sample collection tube is smaller than that of the measuring box, which facilitates further measurement of the drainage fluid volume.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] See Figure 1-2 As shown, the scheme includes a base 1, a drainage fluid recovery box 2 movably disposed in the base 1, a connecting ramp 3 fixed to one side of the base 1, a plurality of metering components 4 passing through the base 1, and a test tube assembly 5 detachably disposed on the connecting ramp 3 and matched with the metering components 4.

[0027] The metering assembly 4 consists of several metering boxes 41 arranged in a gradually decreasing capacity. Each metering box 41 includes a box body 411, a sealing cover 412 hinged to the top of the box body 411, a connecting pipe 413 connected to the sealing cover 412, a drainage fluid overflow hole 414 penetrating the side wall of the box body 411, a guide plate 415 fixed to the outside of the drainage fluid overflow hole 414, an inlet hole 41622 penetrating the other side wall of the box body 411 at a position corresponding to the adjacent drainage fluid overflow hole 414, a first outlet pipe 417 connected to the bottom of the box body 411, a first valve 418 passing through the outlet pipe, a second outlet pipe 419 connected to the bottom of the outer side wall of the box body 411, and a second valve 410 passing through the outlet pipe. Furthermore, the position of the inlet hole 41622 on each metering box 41 is higher than the position of the drainage fluid overflow hole 414.

[0028] The test tube assembly 5 includes several sample collection tubes 51 arranged in an array, a detachable connecting cap 52 located at the opening of each sample collection tube 51, a first drainage conduit 53 with one end connected to a second outlet tube 419 and the other end passing through a connecting cap 52 and located inside a sample collection tube 51, and a second drainage conduit 54 connecting adjacent sample collection tubes 51. In use, the last sample collection tube 51 is not completely sealed to facilitate gas flow. Furthermore, the capacity of the sample collection tube 51 can be 5 ml or 1 ml.

[0029] The base 1 has an installation cavity 11, and the drainage fluid recovery box 2 is slidably disposed in the installation cavity 11; the base 1 has connecting grooves 12 arranged to cooperate with the metering box 41, and the connecting grooves 12 of the base 1 also have through holes 13 that communicate with the installation cavity 11 on the first outlet pipe 417 corresponding to them.

[0030] Furthermore, the metering tank 41 includes a 500ml metering tank 41, a 200ml metering tank 41, a 100ml metering tank 41, a 50ml metering tank 41, a 20ml metering tank 41, and a 10ml metering tank 41. The actual capacity of the 500ml metering tank 41 exceeds 500ml, and the maximum drainage fluid capacity of the 500ml metering tank 41 is set to 500ml. The actual capacity and maximum drainage fluid capacity of the 200ml, 100ml, 50ml, 20ml, and 10ml metering tanks 41 are set to the same as those of the 500ml metering tank 41.

[0031] Furthermore, the drainage fluid recovery box 2 includes a box body and a detachable box cover 21 located at the opening of the box body; a connecting hole is provided on the box cover 21 at a position corresponding to the first discharge pipe 417.

[0032] Furthermore, both the measuring box 41 and the sample collection tube 51 can be provided with volume graduation lines. Optimally, the accuracy of the volume graduation lines on the measuring box 41 and the sample collection tube 51 is set according to their capacities. For example, the 500ml measuring box 41 has graduations of 50ml, 100ml...500ml; the 100ml measuring box 41 has graduations of 10ml, 20ml...100ml; and the 20ml measuring box 41 has graduations of 1ml, 2ml...20ml. The smaller the capacity of the measuring box 41 and the sample collection tube 51, the smaller the spacing between their volume graduation lines.

[0033] Furthermore, the outer side of the connecting ramp 3 is provided with a plurality of test tube limiting grooves 31 along its length direction, which cooperate with the sample collection test tubes 51.

[0034] The working principle is roughly as follows:

[0035] Based on the approximate drainage volume indicated on the container used by the patient to hold the drainage fluid, the measuring boxes 41 are spliced ​​together so that the first outlet tube 417 at the bottom of the measuring box 41 passes through the through hole 13 on the connecting groove 12 and extends into the drainage fluid collection box 2. If the drainage bag contains more than 700 ml but less than 800 ml, and the drainage fluid is estimated to be around 750 ml, the drainage fluid overflow hole 414 of the 500 ml measuring box 41 and the guide plate 415 are connected to the inlet hole 41622 of the 200 ml measuring box 41. Interconnect the drainage fluid overflow hole 414 of the 200ml metering tank 41 with the guide plate 415 and the inlet hole 41622 of the 50ml metering tank 41. Then connect the drainage fluid overflow hole 414 of the 50ml metering tank 41 with the guide plate 415 and the inlet hole 41622 of the 20ml metering tank 41 or 10ml metering tank 41. Connect the second outlet pipe 419 of the 20ml metering tank 41 or 10ml metering tank 41 with the first drainage conduit 53. Finally, connect the drainage fluid carrier container through the drainage tube. Connect the tube 413 on the 500ml metering tank 41. The drainage fluid enters the 500ml metering tank 41. Simultaneously, drainage fluid exceeding 500ml flows through the overflow guide plate 415 into the 200ml drainage tank. Drainage fluid exceeding 200ml then flows through the overflow hole on the 200ml metering tank 41 into the 50ml metering tank 41. Finally, drainage fluid overflowing from the 50ml metering tank 41 flows into either the 20ml or 10ml metering tank 41. Open the second valve 410 to allow the 20ml... The drainage fluid in the measuring box 41 or the 10ml measuring box 41 is fed into the sample collection tube 51. This facilitates the medical staff in taking samples of the drainage fluid into separate tubes for subsequent testing. Furthermore, the sample collection tube 51 has a smaller capacity than the measuring box 41, making it easier to measure the drainage fluid volume. If the drainage bag contains more than 200ml but less than 500ml, the measuring boxes 41 (e.g., 200ml, two, or one 100ml) can be connected sequentially for measurement.

[0036] Finally, by opening the first valve 418 of each metering box 41, the drainage fluid in the metering box 41 is uniformly transferred into the drainage fluid recovery box 2, which is convenient for medical staff to handle centrally.
