Problems solved by technology
[0004] The present invention mainly solves the problem that the connection between the catheter and the urine bag is affected by external force in the market, resulting in inaccurate and large errors in clinical measurement. The connection port with the urine bag is in a suspended state, and there is a gap between the catheter wall and the connection port, so that they have no contact and no force. At the same time, the catheter nozzle is enlarged and larger than the connection port. The gaps do not touch each other and will not generate any force, which not only ensures the accuracy and accuracy of the detection, but also does not make the catheter detached from the urine bag

Embodiment Construction
[0007] A connection device for an unstressed urine bag, characterized in that: a catheter (1) is inserted into the connection port (2) of the urine bag, and the diameter of the catheter (1) is smaller than the diameter of the connection port (2) of the urine bag, The end head of the urinary catheter (1) is provided with an anti-off ring (3), and the diameter of the anti-off ring (3) is greater than that of the urine bag connection port (2).
[0008] The catheter is fixed on the tube clamp of the urine meter, the connection between the catheter and the urine bag is in a suspended state, and there is a gap between the wall of the catheter and the connection, so that they have no contact and no force. The end of the catheter nozzle is equipped with an anti-off ring and its diameter is larger than that of the urine bag connection port (2), so that there is a gap that does not touch each other and does not generate any force, which ensures the accuracy and accuracy of the detection ...

The invention relates to an unstressed urine bag connecting device, wherein a catheter (1) is inserted into a urine bag connection port (2); the diameter of the catheter (1) is smaller than that of the urine bag connection port (2); an anti-drop ring (3) is arranged at the tail end of the catheter (1); and the diameter of the anti-drop ring (3) is greater than that of the urine bag connection port (2). The unstressed urine bag connecting device can be used for eliminating the pressure produced by the connection of the catheter and the urine bag so that a metering instrument is not affected by the interference of external force and thereby being accurate and reliable in measurement; therefore, reliable measurement data is provided for clinical application; and the accuracy of a weighing urine metering instrument is improved.
Description
technical field [0001] The invention relates to a urine bag connecting device, in particular to a non-stressed urine bag connecting device used in a weighing type urine meter. Background technique [0002] In the medical industry, in order to detect whether the patient's various organs are functioning normally, it is necessary to know the patient's intermittent urine volume, urine flow rate and total urine volume, and this product is the urine bag on the weighing urine meter used by medical staff. At present During the use of urine bags on the market, one end of the catheter is connected to the patient's urinary catheter, and the other end is connected to the urine bag of the weighing urine meter, and the urine bag is hung on the lower end of the weighing urine meter. On the weighing hook for measurement, since the catheter is fixed on the connection port of the urine bag, it will be affected by external force, the tube will be stressed unevenly, and the measurement error wi...
