Bladder disease monitor

Abstract

The invention provides a bladder disease monitor, and belongs to the technical field of medical equipment. The bladder disease monitor comprises a lithium ion battery, a sensor conditioning circuit, acontroller and a touch display screen; the lithium ion battery is connected with a 5V voltage stabilizing circuit, and the 5V voltage stabilizing circuit is connected with a resistor stress sensor, adifferential full-bridge conditioning circuit, a 24-bit AD conversion module and a 32-bit single chip controller; the 32-bit single chip controller is connected with the 24-bit AD conversion module,the touch screen and an external storage; and the lithium ion battery provides a portable rechargeable power source for a whole system, through an SD card storage technology, the system can store larger volume of data, and the stability and reliability of data storage are improved. The bladder disease monitor is novel in module structure and clear in working principle, design is conducted by taking the single chip microcomputer STM32F103RCT6 as a core, operation is easy and convenient, trauma is small, the cost is low, the bladder pressure is monitored on line, the bladder disease monitor hasthe advantages of short measuring time, accurate data, high automatic degree and the like, medical workers grasp the condition of patients in time conveniently, and the great application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a disease monitor, in particular to a bladder disease monitor. Background technique [0002] In foreign countries, Kron first proposed the determination of bladder pressure and intravesical pressure (UBP) to solve clinical medical problems. Later, Pottecher advocated that continuous monitoring of UBP can be used to treat abdominal compartment syndrome. In 1987, Takayama et al. reported using their developed A method of measuring bladder pressure with a pressure sensor. The previous method of measuring bladder pressure was mostly to insert a urinary catheter into the bladder, slowly infuse about 50ml of normal saline into the bladder, and then measure the pressure when the fluid flows out of the bladder. This method is simple and practical, and the measured value can truly reflect the human bladder pressure value. But this method has a very fatal shortcoming: every time ...

Problems solved by technology

But this method has a very fatal shortcoming: every time the bladder pressure is measured, it needs to be perfused once, and it is impossible for medical staff to perfuse normal saline continuously. In general intensive care, the perfusion is measured every 4 to 12 hours. Intermittent measurement may affect the medical staff to understand the change of the patient's bladder pressure in a timely manner, and even delay the best time for rescue
