[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] refer to Figure 1A bladder pressure measuring device comprises a pressure sensor 1, a three-way valve 2, a fluid inlet pipe 3, a fluid outlet pipe 4 and a pressure measuring pipe 5 with one end closed, wherein one end of the fluid inlet pipe 3 is connected to the inlet of the three-way valve 2, one end of the fluid outlet pipe 4 is connected to one of the outlets of the three-way valve 2, and the open end of the pressure measuring pipe 5 is connected to the other outlet of the three-way valve 2. It should be understood that the three-way valve 2 is a commonly used valve and can switch between two states. In the embodiment, one state is that the fluid inlet pipe 3 is connected to the fluid outlet pipe 4, and the other state is that the fluid inlet pipe 3 is connected to the pressure measuring pipe 5.

[0018] The pressure sensor 1 is arranged on the pressure measuring tube 5, and is used to detect the internal pressure of the pressure measuring tube 5. In some embodiments, the pressure sensor 1 can be installed at the end of the pressure measuring tube 5 away from one end of the three-way valve 2, that is, the pressure measuring tube is closed by the pressure sensor 1. When the device is used, the fluid inlet tube 3 is placed in the bladder. When the pressure is not measured, the three-way valve 2 is in a state where the fluid inlet tube 3 is connected to the fluid outlet tube 4, and urine is directly discharged from the fluid outlet tube 4; when the pressure is tested, the three-way valve 2 is in a state where the fluid inlet tube 3 is connected to the pressure measuring tube 5, and urine enters the pressure measuring tube 5. The bladder pressure can be detected by the pressure sensor 1. Compared with the prior art, the operation steps are simplified, and there is no need to inject physiological saline, which avoids the influence of physiological saline on the test results, and the measurement results are more accurate.

[0019] The measuring device also includes a controller 6, and the three-way valve 2 is a solenoid valve. The three-way valve 2 is electrically connected to the controller 6, so that the three-way valve 2 can be automatically switched by the controller 6 to achieve automatic pressure relief after the detection is completed. Further, the measuring device of this embodiment also includes a monitoring terminal 7, and the controller 6 includes a processor 601, a wireless transmitter 602, and a display screen 603. The three-way valve 2, the pressure sensor 1, and the display screen 603 are all electrically connected to the processor 601, and the processor 601 and the detection terminal are both connected to the wireless transmitter 602 for communication.

[0020] On the basis of the above, the value measured by the pressure sensor 1 is transmitted to the processor 601, and through the display screen 603, the bladder pressure can be obtained more intuitively, and the measured value is transmitted to the detection terminal in real time through the wireless transmitter 602. Compared with the existing technology, when continuous and uninterrupted measurement is required, medical staff can obtain the patient's bladder pressure remotely, without the need for medical staff to go back and forth to the ward regularly or irregularly to check, thereby reducing the workload of medical staff.

[0021] In this example, the wireless transmitter 602 may be a WI FI device, a Bluetooth device, an Internet of Things device, a wireless sensor, etc. The detection terminal may be a mobile phone, a computer, etc.

[0022] Furthermore, the controller 6 of this embodiment also includes an alarm 604, which is electrically connected to the processor 601, so as to issue an alarm when the measured pressure value is abnormal (for example, exceeds a certain set value), so as to remind medical staff to handle it in time.

[0023] In actual applications, the processor 601 , the wireless transmitter 602 , the display screen 603 and the alarm 604 are arranged in a housing to form a controller 6 , and the controller 6 can be installed on the three-way valve 2 or the pressure measuring tube 5 .

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
