Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to a classified urine collecting device.

Background

In the medical field, urine can be used as a sensitive indicator for determining the physical condition of a patient. In the absence of kidney disease, urine volume is a sensitive indicator of good tissue perfusion in the extracorporeal circulation and the presence of non-blockage of the inferior vena cava. Urine volume per hour is at least 30ml if the kidneys have good perfusion. The collection and recording of urine volume before, during and after the rotation is the most valuable, simple and easy method of extracorporeal circulation operation, is helpful for judging the conditions of in vivo water, kidney function and heart function, such as the smooth urinary tract and insufficient urine volume, and indicates that conditions of low blood volume, low heart rate or insufficient extracorporeal circulation blood flow perfusion or poor inferior vena cava drainage, which cause the rise of renal vein pressure, and the like, and potassium ions and blood volume supplementation should be paid attention to when the urine volume is excessive. At the same time, the specific gravity of urine is measured, and the urine is tested conventionally in extracorporeal circulation, and the crystal supplementing rate can be adjusted accordingly. Therefore, it is of great importance to collect and measure urine from patients.

According to the different physical conditions of every patient, the urination frequency and the urination volume of the patient are in random and irregular states, if medical staff is arranged to pay attention to the urine collection condition of the patient at any time, the medical staff needs to spend additional energy to complete the work, and the condition that the urine collection bag is full but not found in time is easily increased due to the unpredictability of the urination of the patient, so that the patient feels uncomfortable due to the overflow of urine, the infection risk caused by the urine is increased, and additional cleaning work and unnecessary working energy are wasted for the medical staff.

For example, in neurosurgery, long-term surgery makes the patient urinate to a large extent, and a single bag body cannot meet the needs of large-capacity urine collection, and medical staff often pay attention to whether the urine bag is full and handled when needed, dispersing staff's efforts. In addition, to ensure that the test results obtained based on urine analysis accurately reflect the physiological state of the patient, the urine collection device should be able to provide the latest urine for urine analysis instead of urine mixed in the urine bag.

The patent with the bulletin number of CN214105397U discloses an assembled quantifiable urine bag, which comprises a urine bag and an auxiliary urine bag, wherein the urine bag is formed by splicing a cuboid and an inverted square table, folds are symmetrically arranged on the side of the cuboid, a liquid inlet pipe is arranged at the top of the urine bag, a tag bag is arranged on the front surface of the urine bag, a first scale line is arranged on one side of the urine bag, and a first liquid outlet pipe is arranged at the bottom end of the urine bag; the urine bag and the auxiliary urine bag are connected and separated through the arrangement of the integral structure, and the catheter is inserted into the connecting pipe to form a double-layer structure, so that the connection can be reinforced, the connecting pipe is not easy to break, and urine is prevented from leaking; however, the connection position of the auxiliary urine bag and the urine bag is positioned at the top of the urine bag, which is not convenient for placing and fixing the urine bag, and the device also has the defect that medical staff is required to pay attention to the urine collection condition at any time, because the uncertainty of the urination amount of patients, the medical staff cannot master how long the device is full of urine, and the defect that extra energy is required to pay attention to the urine collection condition is not solved.

The sensing device for indicating the urine circulation state or the collection state is also provided in the prior art, so that accurate state indication information can be provided for medical staff, the medical staff can be prevented from continuously spending energy on keeping attention to the device, the attention of the medical staff can be liberated to put into other works, the treatment is not easy to leak, and the nursing quality can be improved. For example, patent publication No. CN218129076U discloses a urine collecting device for male bedridden patients, in which a flow guiding part for guiding urine discharged from a patient into the collecting device and a collecting part for collecting urine discharged from a patient are connected through a flow guiding pipe having an early warning function, a liquid sensor of an early warning component can transmit a signal to an alarm when being immersed by liquid, the alarm can give an alarm to remind a medical staff to process or replace the collecting part, the medical staff is prevented from spending extra effort to observe the collecting state of the collecting device specially, and the burden of the medical staff is reduced. However, the technical solution of this patent is based on the fact that the collecting portion overflows to the flow guiding tube and generates an alarm when the liquid sensor is immersed, and the time left for the medical staff to operate is not too long, especially for the case that the patient is still in a continuous urination state when the alarm is given, urine may not pass through the delivery tube and pollute the collecting portion and the skin of the patient.

The patent with the bulletin number of CN205659185U discloses a urine collecting bag and a urine collecting bag safety monitoring system, which comprises a bag body, wherein one end of the bag body is provided with a liquid leading-in part, the other end of the bag body is provided with a liquid leading-out part, one end of the bag body provided with the liquid leading-in part is externally provided with a hanging part, a contact type liquid level sensor is arranged in the bag body, and the contact type liquid level sensor is electrically connected with a waterproof signal joint penetrating through the side wall of the bag body. The technical scheme disclosed in this patent is to urine collection effect not good of many urine patient, and this technical scheme's collection urine bag capacity is less, even there is early warning device, also needs frequent handling to reach the urine of predetermineeing the height to, this scheme adopts contact level sensor, because urine is from this level sensor's high scale position flow direction low scale position, when urine flow direction low scale position, this sensor easily takes place high misjudgement, and takes place the condition of wrong early warning.

Based on the analysis, due to the randomness and unpredictability of urination of patients, the existing urine classifying and collecting device still needs more extra efforts of medical staff to pay attention to the urine collecting state so as to adjust and replace the urine collecting state in time, especially, the urine collecting device with an early warning device can not obviously improve the workload of the medical staff for processing the overflow alarm state of the device due to the process of long-time surgical operation or the process of multi-round urination of patients caused by the need of a large amount of body fluid supplement during operation; in addition, the existing urine collection device also provides the storage of new urine for urine analysis based on structural design and avoids directly mixing with the urine discharged in advance, so that the urine collection device can provide a hierarchical storage structure for respectively storing the latest urine to be checked and storing the large-capacity urine in the urination process of a plurality of rounds on the basis of being suitable for the large-capacity urine collection process of long-time operation.
