Automatic urinary catheterization system

Abstract

The invention discloses an automatic urinary catheterization system. Closing of a urinary catheterization tube can be automatically controlled according to changing of urine pressure of a human body, automatic urination is realized, the control precision is high, individual control can be realized according to different patients and the current postures of the patients, and the normal bladder functions of a patient are guaranteed to the great extent. In order to precisely and automatically control an automatic urination process, an initial value processing unit, a signal processing unit, a urination threshold value setting unit, a urination channel control unit and an early warning unit are arranged in a control unit of the system; and moreover, an end of a catheter with an electronic liquid draining valve is connected with an intelligent urine volume measuring unit. The initial value processing unit is used for setting initial values of a pressure sensor unit; the signal processing unit is used for processing signals of an acquired value of the pressure sensor unit; the acquired value is compared with a urination threshold value set in the urination threshold value setting unit; and when the acquired value reaches the urination threshold value, a urination channel is opened by using the urination channel control unit.

Description

technical field [0001] The invention relates to an automatic urinary catheterization system, which belongs to the technical field of medical devices. Background technique [0002] In current clinical medicine, indwelling catheterization is a method of retaining the catheter in the bladder to continuously drain urine after catheterization. During the period of indwelling catheterization, the most clinical applications are: open drainage and timed urination. Continuous open drainage will cause the patient's bladder function to decline, and it is easy to cause problems such as dysuria, urinary incontinence, and frequent urination after extubation. Clinically, bladder function training is required for patients before extubation. During the training period, it is completely dependent on manual operation, which increases the burden on family members and medical staff, and brings a lot of inconvenience to people. Regular urination requires manual operation, which increases labor ...

AI Technical Summary

Problems solved by technology

Continuous open drainage will lead to the decline of the patient's bladder function, and it is easy to cause problems such as dysuria, urinary incontinence, and frequent urination after extubation

Clinically, bladder function training is required for patients before extubation. During the training period, it is completely dependent on manual operation, which increases the burden on family members and medical staff, and brings a lot of inconvenience to people.

Regular urination requires manual operation, which increases labor costs; and if the catheter switch is not turned on in time when the patient urinates, urine will leak out, which not only increases the pain of the patient, but may also lead to urinary tract infection and even endanger the patient safety of life

[0003] In view of the above problems, the solution of some products is to install various forms of automatic urination devices on the catheter, but due to the different sizes and structures of catheters from different manufacturers, the automatic urination device is not universal in use

There are also some catheter-assisted technologies, which are mainly based on the improvement of the inherent structure of the catheter; however, the problem that the catheter is a consumable and has a short service life (usually 3-4 weeks to replace) is ignored

Moreover, the new product faces many problems such as long clinical trials, high cost, poor stability, and inconvenient maintenance, so it has not been widely adopted by hospitals at home and abroad.
