Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a urine collection device for urological laparoscopic surgery. Background Art

[0002] Urological laparoscopic surgery is a minimally invasive procedure with advantages such as minimal trauma and rapid recovery. However, during surgery, patients produce urine. If not collected and processed promptly and effectively, it may contaminate the surgical environment, increase the risk of infection, and potentially affect the smooth progress of the surgery and the patient's postoperative recovery.

[0003] During the urine collection process, traditional methods rely mainly on gravity flow, resulting in low collection efficiency. At the same time, the diverter balls used to divert urine from different patients need to be reused and must be cleaned multiple times, which not only increases the risk of cross-infection, but also affects the hygiene and safety during the operation. In addition, due to individual differences between patients and different surgical conditions, the amount of urine produced during surgery is uncertain, which may cause urine overflow and contaminate the surgical environment. Especially when collecting large amounts of urine, traditional methods may cause poor liquid inflow due to insufficient pressure, seriously affecting the surgical effect and failing to meet actual surgical needs.

[0035] See also Figure 1 , which is a schematic diagram of the overall three-dimensional structure of a urine collection device during urological laparoscopic surgery according to the present invention; the urine collection device of the present application can avoid cross infection by adopting a disposable and detachable diverter ball 120, and actively sucks urine by adopting the negative pressure principle, thereby accelerating the urine collection speed; through three collection components connected in series, it can be graded and collected according to the different volumes of urine produced during surgery, effectively coping with the uncertainty of urine production, and avoiding the risk of urine overflow; by controlling the suction volume inside the pressure bag, the internal pressure of the corresponding collection bag can be gradually adjusted to achieve gradual suction of urine; it achieves the technical effects of improving collection efficiency, reducing the risk of cross infection, avoiding urine overflow, improving liquid inlet smoothness, and being able to meet the needs of different surgeries.

[0036] Example 1: Figures 1 to 4 As shown, the present application discloses a urine collection device for urological laparoscopic surgery, comprising a collection bucket 100, a partition plate 101, a movable frame 110, a diverter ball 120, an output tube 130, a sample cartridge 140, a collection portion 200, and a liquid inlet tube 201;

[0037] There are three collecting parts 200, which are evenly arranged along the circumference of the collecting barrel 100 and fixed inside the collecting barrel 100, corresponding to the liquid inlet pipes 201 one by one;

[0038] The collecting portion 200 is provided with a plurality of collecting bags arranged vertically, which are connected in series and are all located below the corresponding liquid inlet pipe 201. The outside of each of the collecting bags is covered with a pressure bag, and a magnet 272 is fixed to the inner wall of each pressure bag. The pressure of the collecting bag inside the bag is adjusted by magnetic attraction to achieve graded extraction and collection of urine.

[0039] The collection bucket 100 is a cylindrical structure made of a transparent material for storing collected urine. The partition plate 101 is a triangular structure fixed inside the collection bucket 100 and is used to separate the collection portion 200. The movable frame 110 is fixed to the bottom of the collection bucket 100 and is used to move the entire collection device. Three liquid inlet pipes 201 are provided, each fixed to the upper end of the collection bucket 100, for transporting different types of human urine.

[0040] The diverter ball 120 is a disposable structure and has three diverter branches 121 at its bottom. Each diverter branch 121 is connected to the corresponding liquid inlet pipe 201 through a cable tie 122, and is used to transport urine to the collection part 200; three output pipes 130 are provided, which are respectively fixed to the bottom of the collection bucket 100 and are used to discharge the urine in the collection bucket 100; three sample cylinders 140 are provided, which are all fixed to the bottom of the collection bucket 100 and are used to store the collected urine samples.

[0041] The collecting portion 200 includes three sets of receiving components, namely a first collecting component 210, a second collecting component 220 and a third collecting component 230;

[0042] The first collecting assembly 210 includes a first filter ball 211, a first collecting bag 212 and a first negative pressure ball 213. The first filter ball 211 is fixed below the liquid inlet pipe 201 and is in communication therewith. The first collecting bag 212 and the first negative pressure ball 213 are fixed below the first filter ball 211 in sequence.

[0043] The second collecting assembly 220 includes a second filter ball 221, a second collecting bag 222 and a second negative pressure ball 223. The second collecting bag 222 and the second negative pressure ball 223 are fixed in sequence below the second filter ball 221.

[0044] The third collecting assembly 230 includes a third filter ball 231, a third collecting bag 232 and a third negative pressure ball 233. The third collecting bag 232 and the third negative pressure ball 233 are fixed in sequence below the third filter ball 231.

[0045] The first collection bag 212, the second collection bag 222 and the third collection bag 232 are all negative pressure bag structures, which are used to actively suck out urine through the negative pressure principle;

[0046] The first filter ball 211 , the second filter ball 221 and the third filter ball 231 are all spherical in structure and are provided with a filter block 260 therein for filtering impurities in urine.

[0047] The diverter ball 120 is used to transport urine from different patients to different collection bags. The first negative pressure ball 213, the second negative pressure ball 223 and the third negative pressure ball 233 are all in a negative pressure state, which is used for urine buffering and maintaining normal flow and pressure balance during the infusion process.

[0048] Further, such as Figure 5 and Figure 6 As shown, the first collecting assembly 210 is fixed inside the collecting barrel 100 via a fixing frame 240 and is connected to the corresponding liquid inlet pipe 201 ; the second collecting assembly 220 and the third collecting assembly 230 are both fixed inside the collecting barrel 100 via a fixing frame 240 .

[0049] The first collection component 210 and the second collection component 220, as well as the second collection component 220 and the third collection component 230 are connected in series via a connecting tube 250 and placed in parallel to achieve graded collection. Through three collection components connected in series, graded collection can be performed according to the different volumes of urine produced during surgery, effectively addressing the uncertainty of urine production and avoiding the risk of urine overflow. At the same time, graded collection allows medical staff to more easily monitor the capacity of each collection component and take timely measures (such as replacing a collection component that is about to overflow), avoiding possible contamination of the surgical environment and interruption of surgery due to urine overflow. The number of collection components can also be increased or decreased according to actual needs to adapt to the needs of different surgeries or patients. Moreover, when the collection components need to be replaced, since they are connected in series and relatively independent, they can be replaced individually without affecting the use of other components, thereby reducing the risk of cross-infection that may be caused by frequent replacement of the entire collection device.

[0050] Further, such as Figures 5 to 7 As shown, the outer sides of the first collection bag 212, the second collection bag 222 and the third collection bag 232 are covered with pressure bag 1 270, pressure bag 2 280 and pressure bag 3 290 in sequence; the pressure bag 1 270, pressure bag 2 280 and pressure bag 3 290 are square plastic-sealed bag structures, the outer layer of which is made of hard material and the inner layer is made of flexible material, and the inner walls of the pressure bag 1 270, pressure bag 2 280 and pressure bag 3 290 are all provided with multiple magnets 272.

[0051] The outer walls of the first collection bag 212, the second collection bag 222 and the third collection bag 232 are fixed with multiple iron sheets 271 that cooperate with the magnets 272, which are used to adjust the internal pressure of the corresponding collection bag through magnetic attraction to achieve gradual suction of urine.

[0052] The interiors of the pressure bag 1 270 , the pressure bag 2 280 , and the pressure bag 3 290 are respectively connected to the air pump through different external pipes, and are used to gradually adjust the internal pressures of the corresponding first collection bag 212 , the second collection bag 222 , and the third collection bag 232 by controlling the suction volume of the pressure bag 1 270 , the pressure bag 2 280 , and the pressure bag 3 290 .

[0053] By controlling the amount of air pumped into the pressure bladder 1 270 , the pressure bladder 2 280 , and the pressure bladder 3 290 , the flexible inner layer thereof is deformed, and then the internal pressure of the collection bag therein is controlled by controlling the deformation of the inner layer and cooperating with the magnetic attraction. At the same time, it can cooperate with the negative pressure ball corresponding to the one located in front of the pipeline, and adjust the pressure in the bag and the pressure in the entire pipeline to control the flow rate of urine entering the negative pressure ball corresponding to the one located in front of the pipeline. It can not only realize the gradual expansion of the first collection bag 212 , the second collection bag 222 and the third collection bag 232 , thereby gradually aspirating urine, but also realize precise control of the expansion speed of the collection bag and control of the urine flow collection speed, further enhancing the stability of the aspiration process. Compared with the traditional method of relying on gravity or one-time aspiration, it can more effectively cope with the collection of large amounts of urine and improve the aspiration efficiency. At the same time, the gradual aspiration design makes the urine collection process smoother, avoiding the problem of rapid expansion of the collection bag or poor collection due to the sudden influx of a large amount of urine.

[0054] During actual operation of the embodiment of the present application, the steps are as follows: first, the diverter ball 120 is connected to different liquid inlet tubes 201 through the cable tie 122 to ensure sealing; then, during the operation, the catheter used in the operation is connected to the input end of the diverter ball 120, and the input channel of the diverter ball 120 is adjusted so that urine passes through the channel and is transported to the collection bag of the corresponding collection component via the corresponding diverter branch 121. The medical staff monitors the capacity of the collection component by observing the collection bucket 100. When a collection component is close to overflowing, the component can be replaced separately without affecting the use of other components; finally, when it is necessary to collect a urine sample, the circulation pipeline of the sample cylinder 140 is started to allow the urine in the negative pressure ball to flow into the sample cylinder 140 through the output tube 130 to complete the sample collection.

[0055] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0056] The use of a disposable detachable diverter ball 120 can avoid the risk of cross-infection caused by reuse and improve the hygiene and safety during the operation; the use of a negative pressure collection bag can actively suck urine, which greatly improves the collection efficiency compared to the traditional gravity flow collection method, especially when the collection container needs to be emptied quickly; at the same time, the collection bag is more flexible than the fixed collection cavity, and different capacities can be selected according to actual needs to adapt to the urine collection needs of different surgical situations; the design of the negative pressure ball makes urine sample collection faster and more accurate; the design of the negative pressure bag structure and the negative pressure ball reduces the contact between urine and the external environment, reduces the risk of urine sample contamination, and ensures the purity of the sample and the accuracy of the test results; it achieves the technical effects of improved collection efficiency, reduced cross-infection risk, avoidance of urine overflow, improved liquid inlet smoothness and the ability to meet the needs of different surgeries.

[0057] Embodiment 2: In order to make the urine suction process smoother, avoid pressure fluctuations or accidental inhalation of external air that interfere with the operation, and improve the flexibility and stability of the device, this application proposes the following technical solutions to address the above technical problems, specifically:

[0058] like Figure 7 and Figure 8 As shown, the iron sheets 271 on both sides of the outside of the first collecting bag 212 , the second collecting bag 222 and the third collecting bag 232 are all arranged in an up-and-down staggered manner.

[0059] The magnets 272 on both sides of the inner walls of the pressure bladder 1 270 , the pressure bladder 2 280 , and the pressure bladder 3 290 are arranged asymmetrically, and the magnets 272 and the corresponding iron sheets 271 are on the same horizontal line.

[0060] During actual use of the embodiment of the present application, the pressure bladder three 290 is first evacuated so that the third collection bag 232 expands to perform the first-level suction of urine, and then the pressure bladder two 280 is suctioned. At this time, the second collection bag 222 expands to perform the second-level suction of urine, and finally the pressure bladder one 270 is suctioned. At this time, the first collection bag 212 expands to perform the third-level suction of urine; the gradual suction strategy can more effectively utilize the capacity of each collection bag, avoid the risk of urine overflow due to the excessive capacity of a single collection bag, and also improve the suction efficiency of the entire collection system.

[0061] The present application ensures a one-to-one correspondence between the magnet 272 and the iron sheet 271 through an asymmetric and staggered arrangement, thereby avoiding accidental contraction or deformation of the corresponding collection bag due to the magnet 272 being sucked into the wrong position during the suction process, so that urine can flow into the corresponding collection bag more smoothly during the suction process, avoiding poor urine flow or splashing due to changes in the shape of the collection bag; by precisely setting the corresponding positions of the magnet 272 and the iron sheet 271, external air can be prevented from being accidentally drawn into the corresponding collection bag during the suction process, and air entry can be prevented from contaminating the urine sample, thereby affecting subsequent test results; at the same time, the staggered expansion design of the corresponding collection bag can increase the expansion amount, thereby further improving the suction effect.

[0062] During the operation, if there is a sudden increase in urine production or the collection bag is about to overflow, medical staff can quickly adjust the capacity of the collection bag by adjusting the suction volume of the pressure bag, making emergency operations simpler and easier, and helping to ensure the smooth progress of the operation.

[0063] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
