Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a drainage bag with the function of taking and retaining specimens. Background Art

[0002] Peritoneal dialysis utilizes the semi-permeable nature of the peritoneum. Prepared dialysate is instilled regularly and regularly into the patient's peritoneal cavity via a catheter, using gravity. Due to the concentration gradient across the peritoneum, solutes from the high-concentration side migrate to the low-concentration side, while water migrates from the hypotonic side to the hypertonic side. Continuous replacement of the peritoneal dialysate eliminates metabolic products and toxic substances from the body and corrects water and electrolyte imbalances.

[0003] The collection of peritoneal dialysis specimens is an important part of clinical testing. Standardized specimen collection can ensure the accuracy of specimen test results, thereby reducing the occurrence of misdiagnosis of diseases and making clinical diagnosis of patients more accurate. Once the peritoneal dialysis fluid drained during peritoneal dialysis treatment at home shows abnormalities such as turbidity, it is necessary to urgently collect peritoneal dialysis fluid routine and culture specimens. Most patients take a whole bag of drained peritoneal dialysis fluid to the hospital urgently. The whole bag of specimens is inconvenient to transport during the journey and is not sealed and does not meet the standard requirements. Peritoneal dialysis patients undergo peritoneal dialysis for a long time and need regular checkups. Peritoneal dialysis specimens must be collected for testing during each checkup or treatment. However, the peritoneal dialysis drainage bag has no sample collection port. Nurses can only puncture the drainage bag with an empty needle to aspirate and collect specimens, which can easily cause contamination of the specimen and the waste liquid treatment environment.

[0004] How to provide a drainage bag and sample storage device for peritoneal dialysis that can standardize and preserve samples without contamination is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this utility model.

[0026] Meanwhile, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0027] See also Figure 1-2 , this embodiment provides a drainage bag with a specimen collection function, which includes a drainage bag body 1, the top of the drainage bag body 1 is connected to a drainage tube 11, the end of the drainage tube 11 away from the drainage bag body 1 is connected to a quick connector 12, the bottom of the drainage bag body 1 is connected to a sampling tube 13, the drainage tube 11 is provided with a first stop valve 14, and the sampling tube 13 is provided with a regulating valve 15; a liquid collecting component 2, the liquid collecting component 2 includes a liquid collecting box 21, the liquid collecting box 21 is connected to a connecting tube 22, the connecting tube 22 is provided with a second stop valve 23, and the end of the connecting tube 22 away from the liquid collecting box 21 is detachably connected to the end of the sampling tube 13 away from the drainage bag body 1.

[0028] Specifically, the drainage tube 11 of the drainage bag body 1 is connected to the peritoneal dialysis tube in the patient's body through the quick connector 12. The quick connector 12 is more convenient to connect and easy to disassemble and install. When the drainage bag body 1 is draining the patient and the drainage fluid in the drainage bag body 1 needs to be sampled, the connecting tube 22 is connected to the sampling tube 13 to complete the connection between the drainage bag body 1 and the liquid collection box 21. The first stop valve 14 on the drainage tube 11 is closed to prevent more drainage fluid from continuously flowing into the drainage bag body 1, and the second stop valve 23 on the connecting tube 22 is opened. Then, the regulating valve 15 is adjusted to control the flow rate of the drainage fluid flowing into the liquid collection box 21 during sampling. The medical staff then squeezes the drainage bag body 1, and the drainage fluid in the drainage bag body 1 flows from the drainage tube 11 to the connecting tube 2 2 and then flows into the liquid collection box 21. When the required drainage fluid is taken, the regulating valve 15 is closed first, and then the second stop valve 23 is closed to ensure that no drainage fluid remains in the connecting tube 22. Then the connecting tube 22 and the sampling tube 13 are disassembled to complete the sampling. The device ensures that the drainage fluid will not come into contact with the outside world during the sampling process, ensuring that the drainage fluid is not affected by the external environment and destroying the components of the drainage fluid itself, thereby ensuring the accuracy of the test. At the same time, the drainage fluid does not come into contact with the external connection, avoiding the contamination and damage of the drainage fluid to the external environment, and avoiding the occurrence of cross infection. At the same time, the liquid collection box 21 is convenient for transportation. After the sampling is completed, ethylene oxide is needed to sterilize the drainage tube 11 and the like to ensure that the patient is not infected. The use of this device avoids the occurrence of inaccurate specimen collection due to human operation factors mentioned in the CQI team's collective study of the ISPD's guidelines for the diagnosis, treatment and prevention of peritonitis.

[0029] In some possible embodiments, the outer circle of the end of the connecting tube 22 away from the liquid collecting box 21 is provided with a thread, and the inner circle of the end of the sampling tube 13 away from the drainage bag body 1 is provided with a thread that is compatible with the thread on the connecting tube 22. The end of the connecting tube 22 away from the liquid collecting box 21 and the end of the sampling tube 13 away from the drainage bag body 1 are detachably connected through threads.

[0030] Specifically, the connecting tube 22 and the sampling tube 13 are connected by a threaded connection, which is tighter and more secure, thus preventing leakage of the drainage fluid. At the same time, the connecting tube 22 is located at the bottom and the sampling tube 13 is located at the top. The thread of the connecting tube 22 is located on the outer circle and the thread of the sampling tube 13 is located on the inner circle. The sampling tube 13 is sleeved in the connecting tube 22. When the sampling is completed, the drainage fluid remaining on the wall of the sampling tube 13 will also flow into the connecting tube 22, further preventing leakage of the drainage fluid.

[0031] In some possible implementations, the liquid collecting box 21 is cylindrical and includes a box body 211 and a box cover 212 . The box cover 212 is screwed onto the box body 211 .

[0032] Specifically, the cylindrical liquid collection box 21 is easier to place and has a large internal capacity. The box cover 212 is detachably connected to the box body 211. When the drainage fluid in the liquid collection box 21 needs to be taken out for testing, the second stop valve 23 can be opened and the drainage fluid can be poured out through the connecting tube 22. At the same time, the box cover 212 can also be opened to pour it out directly. Different methods can be selected according to the amount of drainage fluid required for testing.

[0033] In some possible implementations, a vent hole 16 is provided on the top of the drainage bag body 1 , and an air plug 17 is connected to the vent hole 16 . The capacity of the liquid collection box 21 is not greater than the capacity of the drainage bag body 1 .

[0034] Specifically, when the drainage fluid flows from the drainage bag 1 to the liquid collection box 21, because the drainage bag 1 is a sealed space, it is affected by atmospheric pressure and the drainage fluid in the drainage bag 1 cannot flow directly into the liquid collection box 21. The drainage bag 1 needs to be squeezed. A vent hole 16 and an air plug 17 are provided at the top of the drainage bag 1. When the drainage fluid needs to flow out, the air plug 17 is opened, and the drainage bag 1 is circulated with the atmosphere. The drainage bag will also flow into the liquid collection box 21 under the influence of gravity. After use, the air plug 17 can be plugged with the vent hole 16, which simplifies the operation and is more convenient to use. The liquid collection box 21 samples the drainage fluid in the drainage bag 1. The amount of drainage fluid contained in the drainage bag 1 is not greater than the drainage fluid in the drainage bag 1, avoiding excessive space waste in the liquid collection box 21.

[0035] In some possible implementations, a hook is provided on the top of the drainage bag body 1. The drainage bag body 1 is made of medical polyethylene material, and the drainage bag body 1 is marked with a capacity.

[0036] Specifically, the hook on the top of the drainage bag body 1 can hang the drainage bag body 1, and then sample the drainage bag body 1, which is more convenient to operate. The medical polyethylene material is transparent, and the caregiver can observe the status of the drainage fluid in time. When the color of the drainage fluid is abnormal, sampling can be carried out in time, and the capacity scale records the amount of drainage fluid.

[0037] In some possible implementations, the bottom of the drainage bag body 1 is in an inverted cone shape, and the sampling tube 13 is connected to the inverted cone tip of the drainage bag body 1. The liquid collection box 21 is made of medical polystyrene material and is marked with a capacity scale.

[0038] Specifically, the inverted cone shape at the bottom of the drainage bag body 1 facilitates the drainage fluid in the drainage bag body 1 to flow to the fluid collection box 21 without any residue. The medical polystyrene material is transparent and has a certain hardness. The fluid collection box 21 made of this material is easy to place and transport. The transparent fluid collection box 21 is marked with a capacity scale, and medical staff can accurately take the amount of drainage fluid that needs to be sampled.
