Description

Technical Field

[0001] The present invention belongs to the technical field of urine collection bags, and particularly relates to a clinical urine collection bag for preventing bacterial growth after cardiothoracic surgery. Background Art

[0002] A clinical urine collection bag for preventing bacterial growth after cardiothoracic surgery is a medical care device designed specifically for patients after cardiovascular disease surgery, mainly used for collecting and storing urine, especially suitable for patients who need to stay in bed or have an indwelling urinary catheter after heart surgery.

[0003] Existing urine collection bags usually have relatively single functions and can only function as urine collection. However, after cardiothoracic surgery, a series of postoperative examinations are usually required, such as routine urine tests, urine bacterial culture, and drug sensitivity tests, to evaluate the postoperative recovery. Midstream urine is the urine collected after discarding the first segment of urine during urination, which can minimize the interference of urethral orifice flora on the specimen. To ensure the accuracy of the test, some hospitals use relatively pure midstream urine as the test sample. However, existing urine collection bags usually do not have the function of collecting midstream urine. When it is necessary to collect midstream urine for examination, it is still troublesome for patients to collect urine again. At the same time, existing urine collection bags usually do not have a disinfection function. After the urine collection bag collects urine, the bacteria growing in the urine are likely to retrograde along the urinary catheter to the bladder and kidneys, causing urinary tract infections and affecting the safety of patient use.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Example 1. Refer to Figures 1-7 , a clinical urine collection bag for preventing bacterial growth after cardiothoracic surgery, including a bag body 1. A connecting pipe 2 is provided at the top of the bag body 1. A main pipe 5 is communicated and arranged on one side of the connecting pipe 2 inside the bag body 1. A branch pipe 6 is communicated and arranged on the main pipe 5. A three-way solenoid valve is arranged at the connection between the main pipe 5 and the branch pipe 6. One end of the branch pipe 6 away from the main pipe 5 is communicated and arranged with a collection box 7. A urine collection mechanism is arranged inside the collection box 7. The urine collection mechanism includes a through hole 13 opened inside the collection box 7, and the through hole 13 penetrates into the inside of the branch pipe 6. Front openings 14, middle openings 15 and rear openings 16 are respectively opened inside the collection box 7. Telescopic square pipes 18 are communicated and arranged inside the front openings 14, middle openings 15 and rear openings 16. A bottom box 19 is communicated and arranged at the bottom of the telescopic square pipe 18. Installation plates 20 are fixedly connected to both sides of the bottom box 19. A tension spring 21 is fixedly connected to the installation plate 20. One end of the tension spring 21 away from the installation plate 20 is fixedly connected to the outer side wall of the collection box 7.

[0028] A pull rod 36 is fixedly connected to the outer side wall of the bottom box 19. The pull rod 36 slidably penetrates into the inside of the collection box 7. A cover plate 17 is fixedly connected to one side of the pull rod 36 inside the collection box 7.

[0029] A urine storage box 8 is fixedly connected inside the bag body 1. One end of the main pipe 5 away from the connecting pipe 2 is communicated into the inside of the urine storage box 8. A disinfection and sterilization mechanism is arranged inside the urine storage box 8.

[0030] In this embodiment, during use, first, the operator can connect the connecting tube 2 to the patient's catheter. After the connecting tube 2 is connected to the catheter, when the patient urinates through the catheter, the urine will enter the main tube 5 through the connecting tube 2 under the transportation of the catheter, and then enter the urine storage box 8 through the transportation of the main tube 5. As more and more urine enters the urine storage box 8, under the weight of the urine, the pressing plate 9 will move downward against the elastic force of the pressing spring 11. When the pressing plate 9 moves downward, it will pull the pushing member 33 to move downward synchronously through the connecting plate 12. When the pushing member 33 moves downward, it will contact the end of the sliding plate 28 close to the opening 30 through its contact inclined surface, and along the contact inclined surface of the pushing member 33, push the entire sliding plate 28 in the direction close to the tension spring 29, so that the opening 30 originally located outside the flow tube 27 enters the flow tube 27. When the opening 30 enters the flow tube 27, the antibacterial agent stored in the disinfection box 25 will first pass through the flow tube 27 and then enter the delivery tube 31 through the opening 30, and then enter the urine storage box 8 through the transportation of the delivery tube 31 to sterilize the urine in the urine storage box 8. Driven by the pressing plate 9, the connecting plate 12 continues to move downward. As the connecting plate 12 continues to move downward, after the inclined surface of the pushing member 33 no longer contacts the sliding plate 28, at this time, under the pulling force of the tension spring 29, the sliding plate 28 will return to its original position, and the opening 30 will move back outside the flow tube 27. At this time, the sliding plate 28 will block the flow tube 27 again, so that the antibacterial agent in the disinfection box 25 will no longer enter the urine storage box 8 through the delivery tube 31. Therefore, during the process of the connecting plate 12 driving the pushing member 33 to move downward, the sliding plate 28 will move back and forth, and the opening 30 will intermittently enter the flow tube 27, so that the flow tube 27 quantitatively inputs the antibacterial agent into the urine storage box 8 through the delivery tube 31 for sterilization, preventing bacteria from growing in the urine in the urine storage box 8, avoiding bacteria from retrograding along the urinary catheter to the bladder, causing urinary tract infections, and affecting the safety of the patient's use.

[0031] Embodiment 2, referring to Figures 1-7 , the disinfection and sterilization mechanism includes limiting rails 10 arranged on both sides inside the urine storage box 8. A pressing plate 9 is slidably connected to the inside of the two limiting rails 10 together. Pressing springs 11 are fixedly connected to the inside of the two limiting rails 10, and the other ends of the pressing springs 11 are fixedly connected to the outer side walls of the pressing plate 9.

[0032] Inside the bag body 1, a disinfection box 25 and a sealing box 26 are fixedly connected. An addition port 24 is communicated inside the disinfection box 25, and the addition port 24 penetrates to the outside of the bag body 1. A circulation pipe 27 is communicated inside the disinfection box 25, and the circulation pipe 27 penetrates to the inside of the sealing box 26. A sliding plate 28 is slidably connected inside the circulation pipe 27. A tension spring 29 is fixedly connected to the outer side wall of the sliding plate 28, and the end of the tension spring 29 away from the sliding plate 28 is fixedly connected to the outer side wall of the circulation pipe 27. An opening 30 is formed on the side of the sliding plate 28 away from the tension spring 29. A delivery pipe 31 is communicated at the bottom of the circulation pipe 27, and the end of the delivery pipe 31 away from the circulation pipe 27 is communicated to the inside of the urine storage box 8.

[0033] A connecting plate 12 is fixedly connected to the outer side wall of the pressing plate 9. The connecting plate 12 slidably penetrates to the inside of the sealing box 26. A torsion spring rotating shaft 34 is arranged at the end of the connecting plate 12 away from the pressing plate 9, and a pushing member 33 is arranged on the torsion spring rotating shaft 34.

[0034] A limiting plate 32 is fixedly connected to the outer side wall of the connecting plate 12. The limiting plate 32 is located directly above the pushing member 33. A storage opening 35 is formed inside the connecting plate 12.

[0035] A plurality of conduits 23 are arranged on the bag body 1. The ends of the plurality of conduits 23 are all slidably connected with inserting tubes 22. Electromagnetic valves are arranged inside the plurality of inserting tubes 22. The ends of the plurality of inserting tubes 22 away from the conduits 23 are all communicated to the inside of the corresponding bottom box 19.

[0036] Support legs 3 are fixedly connected to both sides of the bottom of the bag body 1. A discharge pipe 4 is communicated inside the urine storage box 8, and the end of the discharge pipe 4 away from the urine storage box 8 penetrates to the outside of the bag body 1.

[0037] In this embodiment, during use, when it is necessary to collect midstream urine, after the connecting tube 2 is connected to the urinary catheter and the patient urinates through the urinary catheter, the operator can open the three-way solenoid valve at the connection between the main pipe 5 and the branch pipe 6, so that the urine passing through the front end of the main pipe 5 is diverted into the branch pipe 6 through the three-way solenoid valve and no longer enters the urine storage box 8 through the bottom end of the main pipe 5. The initial urine transported to the collection box 7 through the branch pipe 6 will first pass through the front opening 14 and then enter the corresponding bottom box 19 through the telescopic square pipe 18 connected thereto. As the amount of initial urine stored in the bottom box 19 increases, under the action of the gravity of the urine, the bottom box 19 corresponding to the front opening 14 will move downward against the pulling force of the corresponding tension spring 21. When the corresponding bottom box 19 moves downward, it will pull the cover plate 17 connected thereto to move downward synchronously through the corresponding pull rod 36 to block the front opening 14 and prevent the front opening 14 from transporting urine downward. After the front opening 14 stops transporting urine downward, the midstream urine that subsequently enters the interior of the collection box 7 will pass through the middle opening 15 and then enter the corresponding middle-section bottom box 19 through the middle-section telescopic square pipe 18 connected thereto. As the amount of urine stored in the bottom box 19 increases and fills up, under the action of gravity, the middle-section bottom box 19 will overcome the pulling force of the tension spring 21 connected thereto and pull the middle-section cover plate 17 to move downward through the corresponding pull rod 36 to block the middle opening 15 and prevent the middle opening 15 from flowing urine. After the collection of the midstream urine is completed, the terminal urine that finally enters the collection box 7 will, by the same principle, also pass through the rear opening 16 and fill the corresponding bottom box 19 through the telescopic square pipe 18 connected thereto until the bottom box 19 moves downward and pulls the corresponding cover plate 17 to block the rear opening 16. When all three bottom boxes 19 are full, the operator can first stably place a clean urine cup below the port where the catheter 23 extends outside the bag body 1, and then open the solenoid valves in the three intubation tubes 22. At this time, the initial urine, midstream urine, and terminal urine stored in the three bottom boxes 19 will all be transported into the urine cup through the corresponding catheter 23. After the collection of the initial urine, midstream urine, and terminal urine is completed, the urine cup containing the midstream urine can be taken as a test sample for routine urine tests and other examinations to detect the recovery status after cardiothoracic surgery. After the detection of the midstream urine is completed, the urine cups containing the initial urine and terminal urine can also be subjected to corresponding tests, such as the detection of urinary tract infections in patients, to facilitate the postoperative recovery of the patients.

[0038] It should be noted that usually, after cardiothoracic surgery, the urine volume of a patient is usually 400 milliliters. In this solution, the capacities of the front-section bottom box 19 and the middle-section bottom box 19 are 100 milliliters, and the capacity of the rear-section bottom box 19 is 200 milliliters, ensuring that all the urine excreted by the patient at one time can be collected by the three bottom boxes 19.

[0039] It should be noted that when the urine storage box 8 is full of urine, the urine can be discharged through the discharge pipe 4. After the urine in the urine storage box 8 is discharged, under the elastic force of the pressing spring 11, the pressing plate 9 will return to its original position. At this time, the connecting plate 12 will drive the pushing member 33 to move upward synchronously. The top of the upward moving pushing member 33 will contact the end of the sliding plate 28. At this time, under the push of the sliding plate 28, the pushing member 33 will flip towards the receiving port 35 until it is no longer blocked by the sliding plate 28. When the entire pushing member 33 moves to the upper end of the sliding plate 28, under the elastic force of the torsion spring shaft 34, the pushing member 33 will flip back to its original position. Blocked by the limiting plate 32, the pushing member 33 can only flip downward and cannot flip upward.

[0040] It should be noted that the bag body 1 is a square rigid urine bag, mostly made of lightweight and strong plastics or composite materials, such as polypropylene, polycarbonate, etc. These materials not only have a certain hardness to protect the internal structure of the urine bag.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
