Description

A real-time monitoring pressure urinary catheter

technical field

The utility model is used in the technical field of medical supplies, in particular to a pressure catheter capable of real-time monitoring.

Background technique

Neurogenic bladder refers to bladder and urethral dysfunction caused by damage to the central nervous system or peripheral nerves that control the voiding function. Poor urination or urinary retention is one of the most common symptoms, and the resulting urinary complications, such as upper urinary tract damage and renal failure, are the main causes of death in patients. Indwelling catheterization is the most commonly used method, and intermittent catheterization is an internationally recognized treatment method, but repeated catheterization also increases the pain of patients, and the most important thing is to master the time of catheterization. The existing technology generally uses drinking water voiding table To carry out, this method is very inconvenient to operate and use.

Utility model content

In order to solve the above problems, the utility model provides a real-time monitoring pressure urinary catheter, which can see the change of bladder pressure in real time on the body surface and reduce the suffering of patients.

The technical solution adopted by the utility model to solve the technical problem is: a real-time monitoring pressure urinary catheter, including a tube body, the far end of the tube body is provided with a urine inlet, and the outside of the tube body is provided with a urine inlet on the back side of the urine inlet. There is a limit ring, the proximal end of the tube is provided with an urination port, and a catheterization channel leading to the urination port and the urination port is formed in the tube body, and the tube body includes an inner tube body and an outer membrane, and an inner tube body and an outer membrane A cavity is formed between them, and the proximal end of the tube body is provided with an inflatable tube that communicates with the cavity. A pressure measuring tube connected with the catheterization channel, a pressure sensor and a pressure gauge connected with the pressure sensor are arranged in the pressure measuring tube.

As a further improvement of the technical solution of the utility model, the pressure measuring tube is also provided with an alarm connected to the pressure sensor.

As a further improvement of the technical solution of the present utility model, the limiting ring is an annular bag formed by the outward swelling of the outer membrane.

As a further improvement of the technical solution of the utility model, a connecting film extending along the tube body is provided between the inner tube body and the outer membrane.

As a further improvement of the technical solution of the utility model, the distal end of the pipe body has a dome, and the urine inlet is opened on the wall of the pipe body behind the dome.

The beneficial effect of the utility model: when the urinary catheter is inserted into the bladder and fixed, the urination port is closed, the pressure sensor detects the pressure in the bladder, and the pressure data is displayed in real time through the pressure gauge, that is, the change of the bladder pressure can be seen in real time on the body surface, Thereby opening and closing the urinary catheter clip according to the pressure, simulating the physiological conditions such as bladder contraction and expansion, maintaining bladder function, performing bladder function exercise, reducing urinary tract infection, and protecting kidney function. In addition, the tube body in the utility model is a double-layer structure including an inner tube body and an outer membrane. Before the catheter is inserted, the air in the inflatable cavity is evacuated, and the diameter of the tube body becomes smaller. The inflatable tube pumps air into the cavity, and the outer membrane expands to increase the outer diameter of the tube. The outer membrane of the tube body is closely attached to the urethra, which prevents the tube body from loosening and falling off, and also reduces the irritation to the trigone and urethral mucosa. Discomfort.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model.

detailed description

With reference to Fig. 1, it has shown the concrete structure of the preferred embodiment of the present utility model. The structural features of each element of the present utility model will be described in detail below, and if there is a description of the direction (up, down, left, right, front and back), the structure shown in Figure 1 is used as a reference description, but the utility model The actual use direction is not limited to this.

The utility model provides a pressure catheter capable of real-time monitoring, which comprises a tube body 1, the distal end of the tube body 1 is provided with a urine inlet 2, and the outer side of the tube body 1 is provided with a limit ring behind the urine inlet 2, The proximal end of the tube body 1 is provided with an urination port 3, and a catheterization channel leading to the urine inlet port 2 and the urination port 3 is formed in the tube body 1, and the tube body 1 includes an inner tube body 4 and an outer membrane 5, so A connecting film extending along the tube body 1 is provided between the inner tube body 4 and the outer membrane 5 . A cavity is formed between the inner tube body 4 and the outer membrane 5, and the proximal end of the tube body 1 is provided with an inflatable tube 6 that communicates with the cavity. After the cavity is inflated, a stretched tube body can be formed on the outside of the inner tube body 4 1, the proximal end of the tube body 1 is provided with a pressure measuring tube 7 connected with the catheterization channel, and the pressure measuring tube 7 is provided with a pressure sensor 8 and a pressure gauge 9 connected with the pressure sensor 8.

When the urinary catheter is inserted into the bladder and fixed, the urination port 3 is closed, the pressure sensor 8 detects the pressure in the bladder, and the pressure data is displayed in real time through the pressure gauge 9, that is, the change of the bladder pressure can be seen in real time on the body surface, so that according to the pressure situation Open and close the urinary catheter clip to simulate physiological conditions such as bladder contraction and expansion, maintain bladder function, exercise bladder function, reduce urinary tract infection, and protect kidney function. In addition, the tube body 1 in the utility model is a double-layer structure including an inner tube body 4 and an outer membrane 5. Before the catheter is inserted, the air in the inflatable cavity is evacuated, and the diameter of the tube body 1 becomes smaller. After insertion, pump air into the cavity through the inflatable tube 6, and the outer membrane 5 expands to increase the outer diameter of the tube body 1. The outer membrane 5 of the tube body 1 is closely attached to the urethra, preventing the tube body from loosening and falling off, and reducing the pressure on the tube body. Stimulation of bladder trigone and urethral mucosa reduces discomfort.

In addition, the pressure measuring tube 7 is also provided with an alarm connected to the pressure sensor 8 . When the pressure in the bladder exceeds the set value, the alarm can send out sound and light alarm information.

The limiting ring is an annular sac 10 formed by the outward swelling of the outer membrane. The annular bag 10 is inflated after the inflatable cavity is inflated, so that the tube body 1 is limited in the bladder and prolapse is avoided. When the urinary catheter needs to be taken out, open the inflatable tube to release the gas in the annular bag 10 and the inflatable cavity, and the diameter of the tube body becomes smaller, which facilitates the extraction of the tube body.

The distal end of the tube body 1 has a dome, and the urine inlet 2 is provided on the tube wall of the dome rear side. The dome is convenient for the insertion of the tube body, and avoids scratching the urethra due to the tip of the tube body.

Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art can also make equivalent modifications or replacements without violating the spirit of the present utility model. These equivalent modifications or replacements are all included in the claims of this application. within the limited range.
