Example 1

Referring to fig. 1, the present embodiment provides a bladder detector 100, which includes a urinary catheter 10, a water storage device 20, a temperature control device 30, and a water column pressure gauge 40.

The water storage device 20 is provided with a water storage cavity 21, the urinary catheter 10 is provided with a first end 101 communicated with the water storage cavity 21 and a second end 102 extending into the bladder cavity 210 of the human body, a temperature sensor 123 for detecting the temperature in the bladder cavity 210 is arranged at the position, close to the second end 102, of the urinary catheter 10, a connecting part 103 is arranged in the middle of the urinary catheter 10, the urinary catheter 10 is divided into a first pipe 11 and a second pipe 12 which can be switched on and off by the connecting part 103, the first end 101 is positioned on the first pipe 11, a water column pressure gauge 40 is communicated with the connecting part 103 through a switchable connecting pipe 41, and the temperature control device 30 is used for receiving a temperature signal output by the temperature sensor 123 and adjusting the water temperature in the water storage cavity 21.

Specifically, the bladder detector 100 can timely detect the temperature in the bladder cavity 210 of the human body through the temperature sensor 123, timely adjust the water temperature in the water storage cavity 21, ensure that the water temperature can not stimulate the bladder 200 of the human body, have obvious uncomfortable feeling to the bladder 200 of the human body, and can relatively intuitively analyze the relationship between different water quantities in the bladder cavity 210 and the pressure thereof through the flow of the output water and the data displayed through the water column pressure gauge 40 when the water is output into the bladder cavity 210 through the water storage cavity 21. The design is ingenious and reasonable, the structure is simple and compact, the manufacturing cost of the whole instrument is low, and the market application potential is huge.

It should be explained here that the bladder cavity 210 is a cavity of the bladder 200 itself for accommodating urine to be discharged outside the body.

It should be noted that, the water storage device 20 may be made of transparent glass, and scale marks may be disposed on the transparent glass, so as to help a user more intuitively observe the flow of the water. The approximate flow rate can also be deduced. The whole process is simple to operate and has better use effect.

It should be noted here that the urinary catheter 10 may be used as the urinary catheter 10.

The catheter 10 is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride (PVC), and can be inserted into the bladder 200 through the urethra so as to drain urine, after the catheter 10 is inserted into the bladder 200, an air bag is arranged near the head end of the catheter 10 to fix the catheter 10 and remain in the bladder 200, so that the catheter is not easy to break off, and the drainage tube is connected with a urine bag to collect urine. The catheter 10 is of 13 types according to the circumference of the outer diameter of 6F-30F, and the common adult catheters are of four types of 12F, 14F, 16F and 18F, wherein the F number is the millimeter number of the outer circumference.

In a specific implementation, two types of urinary catheter 10, 12F and 14F, may be used, and the length of which may be selected to be 100cm. The urinary catheter 10 is disposable, so that cross infection can be effectively avoided.

Referring to fig. 2, the water column pressure gauge 40 intuitively indicates the water pressure by displaying the height of the water column, and when in use, the zero scale line of the water column pressure gauge 40 and the liquid to be measured are kept at the same height, the water column tube 401 and the connecting tube 41 inside the water column pressure gauge 40 are in a communication state, and under the action of atmospheric pressure, the water in the water column tube 401 rises to a certain height, and the height reflects the pressure of the liquid to be measured.

It should be noted that, the water column tube 401 may be a transparent glass tube, and the graduation marks disposed thereon can help the user to observe the corresponding graduation values better.

The formula: p=ρgh

ρ: represents the density of the liquid;

g: representing gravitational acceleration;

h: representing the height of the display.

In use, roughly the density of water=1000 kg/m3; g=10n/kg.

Thus 1 cm water column = 100 pa = 0.1 kpa

Optionally, the number of the temperature sensors 123 is multiple, and the multiple temperature sensors 123 operate simultaneously, so that the accuracy of final measurement is high, and the overall use effect is good.

Optionally, the bladder detector 100 further comprises a flow rate control device 50, wherein the flow rate control device 50 is used for controlling the flow rate of water delivered into the urinary catheter 10 by the water storage device 20.

In practice, the flow rate is often controlled within the range of 20-30ml/min, the stimulation of the flow rate within the range to the human bladder 200 is minimum, and the final data is accurate.

In the implementation, the flow rate can be controlled in the range of 0-20ml/min or more than 30ml/min, the feeling of a patient can be known through different flow rates, more data favorable for the development of medical technology can be obtained through comparison, and the clinical operability is improved.

Optionally, the bladder detector 100 further comprises a switch control device 80, valves are arranged on the first tube 11, the second tube 12 and the connecting tube 41, and the switch control device 80 is used for controlling the valves to be opened or closed.

In order to better distinguish the three valves, the valve disposed on the first pipe 11 is a first valve 111, the valve disposed on the second pipe 12 is a second valve 121, and the valve disposed on the connecting pipe 41 is a third valve 411.

The three valves operate independently, and when only the second pipe 12 and the water column pressure gauge 40 are required to communicate, the first valve 111 is closed, and the second valve 121 and the third valve 411 are opened. When only the first pipe 11 and the second pipe 12 are required to communicate, the third valve 411 is closed, and the first valve 111 and the second valve 121 are opened. By combining the opening or closing of the three valves, different effects can be achieved.

Optionally, the bladder detector 100 further comprises a flow control device 60, wherein the flow control device 60 is used for controlling the flow rate of the water delivered into the urinary catheter 10 by the water storage device 20.

In a specific operation, if 50ml is used as the unit water flow, 50ml of water can be firstly delivered into the bladder cavity 210, the data displayed by the water column pressure gauge 40 is observed, 50ml of water is then delivered, the data of the water column pressure gauge 40 is observed, and the relationship between the water capacity in the bladder cavity 210 and the pressure born by the water column pressure gauge 40 is obtained through calculation. The whole use effect is better. It is also possible to use 25ml or 75ml or 100ml as the unit water flow.

Optionally, the bladder detector 100 further includes a display 70, where the display 70 is configured to display the temperature value detected by the temperature sensor 123, the water temperature in the water storage chamber 21, the flow rate of the water delivered to the urinary catheter 10 by the water storage device 20, and the flow rate of the water delivered to the urinary catheter 10 by the water storage device 20.

The display screen 70 can help the user to more intuitively understand the temperature value in the bladder cavity 210, the water temperature in the water storage cavity 21, the flow rate of the water delivered to the urinary catheter 10 by the water storage device 20 and the flow rate of the water delivered to the urinary catheter 10 by the water storage device 20. The real-time dynamic display can help a user to monitor the whole use process better, improve the test accuracy and ensure that patients have no obvious uncomfortable feeling in the whole use process.

Optionally, the temperature sensor 123 is located within a range of 1-3cm from the second end 102 of the urinary catheter 10.

In this range, the measured temperature value is more accurate, and the discomfort to the human body is avoided, so that the whole use effect is better.

Optionally, a three-way pipe is provided at the connection portion 103, through which the first pipe 11, the second pipe 12 and the connection pipe 41 communicate.

The pipe joint with three openings is called a three-way pipe. The name is three ports, namely an inlet and two outlets; or two inlets and one outlet. The pipeline has T-shape and Y-shape, has equal diameter pipe orifice and reducing pipe orifice, and is used for the joint of three identical or different pipelines.

Alternatively, the connecting tube 41 is detachably connected to the tee.

When the patient needs to urinate, the second valve 121 is opened, the first valve 111 is closed, the connecting tube 41 is removed, and at this time, the second tube 12 corresponds to the urinary catheter 10, and the urine of the patient is urinated through one opening of the three-way tube by removing the connecting tube 41. The use function is various, and the operability is strong.

Referring to fig. 3, optionally, the first pipe 11 is provided with a check valve 113, and the check valve 113 is used to enable water in the water storage chamber 21 to flow to the second pipe 12 in one direction.

The check valve 113 is shown between the first end 101 and the first valve 111, and may be disposed between the first valve 111 and the connection 103.

The check valve 113 is provided to prevent the liquid in the second pipe 12 from flowing back into the water storage device 20, and since urine of a patient may exist in the second pipe 12, if the backflow phenomenon occurs, the water storage device 20 may be contaminated. By adding the check valve 113, this problem can be effectively solved.

It should be noted that, in a specific implementation, the urinary catheter 10, the connection tube 41 and the water column tube 401 have a space capable of accommodating a certain amount of water, and in the implementation, water can be introduced into the tube in advance through the water storage device 20, and meanwhile, the water column pressure gauge 40 is ensured to be at a predetermined position, and the water level is kept at a zero scale mark, so that the accuracy of the whole test is ensured.

Before implementation, the urinary bladder 200 can be catheterized, so that urine in the bladder cavity 210 can be drained as much as possible, and the accuracy of the test can be improved.

According to the bladder detector 100 provided by the embodiment of the invention, the working principle of the bladder detector 100 is as follows:

normal bladder 200 stores urine to 450-550ml to initiate a micturition reflex, pressure within bladder 200 is maintained at 15-18cmH all the time ₂ O, when the pressure in the bladder 200 is greater than 40cmH ₂ At O, regurgitation of ureter 10 will occur, resulting in hydronephrosis and impairment of renal function, so that for safe urine storage and regular urination, a corresponding monitoring is necessary to understand the safe volume within bladder 200.

By filling bladder cavity 210 with a quantity of water at a temperature approximately equal to the temperature in bladder cavity 210, the water column height displayed by water column pressure gauge 40 is observed, and multiple tests are performed to measure the corresponding pressure values of bladder cavity 210 at different capacities of water input into bladder 200.

Example 2

The present embodiment also provides a method for using the bladder detector 100, and the structure of the bladder detector 100 may refer to embodiment 1, and the technical solution disclosed in embodiment 1 will not be repeated.

Specifically, the method comprises the following steps:

step S100: the control switch 80 closes the valve on the first tube 11, inserting the urinary catheter 10 through the urethra with the second end 102 positioned within the bladder cavity 210 of the human body;

step S200: the temperature control device 30 receives the signal output by the temperature sensor 123 and adjusts the water temperature in the water storage chamber 21;

step S300: the control switch control device 80 is controlled to open the valve on the first pipe 11, so that the water storage cavity 21 and the bladder cavity 210 are in a communicated state;

step S400: controlling the flow rate control device 50 and the flow rate control device 60 so that the water storage chamber 21 outputs a unit flow rate of water to the bladder chamber 210;

step S500: the control switch control device 80 is controlled to close the valve on the first pipe 11, open the valve on the second pipe 12 and the communicating pipe, enable the water column pressure gauge 40 to be communicated with the bladder cavity 210, adjust the relative height of the water column pressure gauge 40, enable the zero scale on the water column pressure gauge 40 to be the same as the height of the bladder cavity 210, and read out the data on the water column pressure gauge 40.

Specifically, the temperature control device 30 is controlled by the method to adjust the water temperature in the water storage cavity 21 to reach the temperature in the bladder cavity 210 of the human body, so that the method has small stimulation to the human body and higher detection precision, can also adjust the water temperature to be in a low-temperature state, is used for stimulating the bladder 200 of the human body, and has remarkable curative effect on treating patients with urination delay.

It should be noted that, before step S100, the water storage device 20 may be controlled to lead the water in the water storage chamber 21 to the urinary catheter 10 so that the entire urinary catheter 10 is filled with water, and the third valve 411 may be in a closed state or an open state.

If in the open state, it is necessary to ensure that the water enters the water column tube 401, and the height is located at the zero scale mark, so as to avoid influencing the test result.

If in the closed state, the space within connecting tube 41 and water column tube 401 is ignored throughout the test.

For more accurate testing, the second valve 121 is positioned near the second end 102 of the second tube 12 to ensure that water can fill the entire urinary catheter 10 during the pre-infusion process.

In step S500, the water column pressure gauge 40 is adjusted to make the zero scale line and the position of the human bladder 200 relatively level, so as to improve the accuracy of the pressure test in the bladder cavity 210.

Example 3

Referring to fig. 4, the present embodiment also provides a method for using the bladder detector 100, and the structure of the bladder detector 100 can refer to embodiment 1, and the disclosed technical solution of embodiment 1 will not be repeated.

Specifically, this embodiment differs from embodiment 2 in that in step S100, the connection tube 41 is removed, the connection tube 41 is separated from the urinary catheter 10, and the control switch control device 80 is controlled to open the valve in the second tube 12, so that the urination operation is performed.

The purpose of closing the first valve 111 is to prevent urine from possibly entering the reservoir 21, and after removing the connection tube 41, the second valve 121 is opened and urine is discharged from the connection 103 through the second tube 12.

If the connection portion 103 is a three-way pipe to connect the connection pipe 41, the first pipe 11 and the second pipe 12, then a new pipe can be directly attached while the connection pipe 41 is detached, thereby facilitating urination.

Example 4

Specifically, this embodiment differs from embodiment 2 in that in step S200, the temperature control device 30 is controlled to adjust the water temperature in the water storage chamber 21 so as to be the same as the temperature in the bladder chamber 210.

When the water temperature in the water storage cavity 21 is the same as or almost the same as the temperature in the bladder cavity 210, the water in the water storage cavity 21 enters the bladder cavity 210, so that the stimulation to the human body is small, and the human body has no obvious uncomfortable feeling. Avoiding the entry of water at an improper temperature into the bladder cavity 210 allows the patient to have a greater response, ultimately affecting the accuracy of the test.

Example 5

Specifically, this embodiment differs from embodiment 2 in that in step S200, the temperature control device 30 is controlled to adjust the water temperature in the water storage chamber 21 to a temperature of-5 ℃ to 0 ℃.

For some patients with extremely low detrusor tension in bladder 200, a portion of urine will often be stored in bladder chamber 210 and not be expelled, at which point the water in reservoir chamber 21 may be reduced to-5℃ to 0℃, and the detrusor in bladder chamber 210 may be stimulated to urinate by the water at that temperature.

The bladder wall consists of three layers of tissue, namely a mucous membrane layer, a muscle layer and an adventitia from inside to outside. The muscular layer is made up of smooth muscle fibers called the detrusor muscle, which contracts, causing the internal pressure of the bladder 200 to rise, forcing urine out of the urethra.

In summary, the present invention provides a bladder detector 100, the bladder detector 100 can timely detect the temperature in the bladder cavity 210 of the human body through the temperature sensor 123, timely adjust the water temperature in the water storage cavity 21, ensure that the water temperature can not stimulate the bladder 200 of the human body, and have no obvious uncomfortable feeling to the bladder 200 of the human body, when water is output into the bladder cavity 210 through the water storage cavity 21, the relationship between different water amounts in the bladder cavity 210 and the pressure thereof can be intuitively analyzed through the output water flow and the data displayed through the water column pressure gauge 40, and the whole process is simple to operate. The design is ingenious and reasonable, the structure is simple and compact, the manufacturing cost of the whole instrument is low, and the market application potential is huge.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
