[0032] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] The following further describes the present application in detail with reference to the accompanying drawings of the specification.

[0034] The embodiments of the present application disclose a urinary catheter and a detection method for detecting urinary tract infection conditions.

[0035] As Figure 1 shown, a urinary catheter for detecting urinary tract infection conditions includes a urinary catheter body 1, a catheter 2, a detection tube 3, and a detection member 4. A first urine drainage pipeline is formed in the urinary catheter body 1; the catheter 2 is arranged at one end of the urinary catheter body 1, and a second urine drainage pipeline is formed in the catheter 2, and the second urine drainage pipeline is communicated with the first urine drainage pipeline; one end of the detection tube 3 is arranged on the urinary catheter body 1, and a detection pipeline is formed in the detection tube 3, and the detection pipeline is communicated with the first urine drainage pipeline; the detection member 4 is arranged at the other end of the detection tube 3, and a storage space is formed in the detection member 4, and a detection reagent is stored in the storage space. The detection reagent is used to react with the infected urine to produce a color reaction, and the storage space is communicated with the detection pipeline.

[0036] When the patient urinates, while the urine is discharged from the catheter 2, part of the urine will flow into the detection pipeline and finally into the detection member 4. The urine discharged by the patient will be mixed with the detection reagent. If the patient's urine is infected, the infected urine will react with the detection reagent, and the detection reagent will change color. Therefore, medical staff can predict whether the patient has urinary tract infection by whether the detection reagent changes color, solving the problem that the existing infection detection method has a lag and cannot understand the patient's infection situation during the catheterization process.

[0037] As Figure 1 shown, the catheter 2 and the detection tube 3 are arranged on the same side of the urinary catheter body 1.

[0038] Specifically, one end of the urinary catheter body 1 is used to be inserted into the patient's bladder. The catheter 2 and the detection tube 3 are both arranged at the other end of the urinary catheter body 1. That is, the catheter 2 and the detection tube 3 form two branches respectively at the other end of the urinary catheter body 1. After the urine in the patient's bladder enters the first urinary duct, it flows from one end to the other end along the first urinary duct. Then it will be divided into two paths at the other end. One path enters the second urinary duct and is discharged, and the other path enters the detection duct and finally enters the storage space to be mixed and reacted with the detection reagent. Thus, medical staff can predict and judge whether the patient has a urinary tract infection by whether the detection reagent changes color.

[0039] The catheter 2 and the detection tube 3 are both arranged on the same side of the urinary catheter body 1, which is convenient for the urine in the first urinary duct to be branched and enter the second urinary duct and the detection duct, and the situation that the urine in the first urinary duct only enters one of the second urinary duct and the detection duct will not occur.

[0040] Such as Figure 1 shown, the detection part 4 is detachably arranged on the detection tube 3.

[0041] Specifically, the detection part 4 is detachably arranged on the detection duct, which is convenient for the operator to replace, clean the detection part 4 at any time or remove the detection part 4 at any time to replace the detection reagent in the storage space.

[0042] The detachable method is not limited here. Various means such as screwing and buckling can be adopted between the detection part 4 and the detection tube 3.

[0043] In this embodiment, the detection part 4 is screwed to the end of the detection tube 3 far away from the urinary catheter body 1. A screw interface is arranged on the detection part 4, and an external thread for screwing is arranged on the screw interface. An internal thread for screwing with the external thread is arranged at one end of the detection tube 3, and the screw interface can be screwed to the end of the detection tube 3.

[0044] Furthermore, a sealing ring is sleeved on the outer periphery of the screw interface. After the screw interface is screwed to the detection tube 3, the sealing ring can be clamped between the end face of the detection tube 3 and the end face of the screw interface to prevent the urine in the detection duct or the detection reagent in the storage space from leaking to the outside.

[0045] Such as Figure 1 and Figure 2As shown, the detection tube 3 includes a detection tube body 31 and a one-way check member 32. A detection pipeline is formed inside the detection tube body 31. One end of the detection tube body 31 is disposed on the urine tube body 1, and the one-way check member 32 is disposed at the other end of the detection tube body 31. The detection member 4 is detachably disposed on the one-way check member 32. The one-way check member 32 is used to ensure that urine enters the storage space and prevent the detection reagent from entering the first urine pipeline; a one-way check member 32 is provided between the detection tube 3 and the detection member 4, and the detection member 4 is detachably disposed on the one-way check member 32.

[0046] Specifically, the one-way check member 32 is a one-way valve. A one-way valve refers to a valve with a single flow direction. The flow direction of the one-way valve is the flow direction of urine entering the storage space, that is, the patient's urine can smoothly pass through the one-way check member 32 from the detection pipeline and flow into the storage space, but the detection reagent in the storage space cannot flow into the detection space through the one-way check member 32.

[0047] The setting of the one-way valve can prevent the occurrence of medical accidents caused by operator errors or inattentiveness when using a urine tube for detecting urinary tract infections. For example, when the detection member 4 is placed above the detection tube 3, the detection reagent in the storage space flows into the detection pipeline under the action of gravity, and then mixes into the urine in the first urine pipeline and is discharged and collected by the catheter 2, or even flows backward through the first urine pipeline into the patient's body, resulting in serious medical accidents.

[0048] Such as Figure 1 and Figure 2 As shown, the detection tube 3 includes a pipeline conduction control member 33. The pipeline conduction control member 33 is connected to the one-way check member 32, and the pipeline conduction control member 33 is used to control the conduction or closing of the detection pipeline.

[0049] Specifically, the pipeline conduction control member 33 is a throttle valve. A throttle valve refers to a valve with adjustable flow rate.

[0050] When the throttle valve is closed, the urine in the detection pipeline cannot flow into the storage space. When the throttle valve is opened, the flow area can be adjusted to control the flow rate of the urine in the detection pipeline flowing into the storage space.

[0051] The connection order of the pipeline conduction control member 33 and the one-way check member 32 can be set as needed, that is, the pipeline conduction control member 33 can be disposed between the detection tube 3 body and the one-way check member 32, or the one-way check member 32 can be disposed between the detection tube 3 body and the pipeline conduction control member 33.

[0052] In this embodiment, to prevent residual urine from leaking out from the connection between the detection member 4 and the detection tube 3 after the detection member 4 is removed, the pipeline conduction control member 33 is disposed between the detection tube 3 body and the one-way check member 32.

[0053] The detection tube body 31, the one-way check member 32, and the pipeline conduction control member 33 are detachably connected to each other, such as by screwing. The detachable connection between the detection tube body 31, the one-way check member 32, and the pipeline conduction control member 33 facilitates the replacement of the one-way check member 32 and the pipeline conduction control member 33 and the adjustment of the connection sequence of the pipeline conduction control member 33 and the one-way check member 32 as needed.

[0054] Furthermore, to improve the overall connection tightness, sealing rings are provided at the joints between the detection tube body 31, the one-way check member 32, and the pipeline conduction control member 33.

[0055] The detection reagent is Griess reagent.

[0056] Specifically, the urinary tract detection method of the present application uses the Griess reagent colorimetric method, and the detection reagent is Griess reagent. If a patient is infected with bacteria having nitrate reductase (such as common urinary tract pathogenic bacteria such as Escherichia coli), such bacteria can reduce nitrate in urine to nitrite, and the Griess reagent can react with nitrite to form a magenta dye, so that the operator can judge therefrom that the patient is infected with bacteria having nitrate reductase (such as common urinary tract pathogenic bacteria such as Escherichia coli).

[0057] The detection member 4 is a transparent detection member.

[0058] Specifically, the transparent property of the detection member 4 facilitates the operator to observe the color change of the detection reagent in the detection member 4 at any time, so as to facilitate quick judgment and predict in advance whether the urinary system of the patient is infected. The detection member 4 can be made of transparent glass material.

[0059] Such as Figure 1 As shown, the urinary catheter for detecting urinary tract infection conditions includes an airbag assembly 5, and the airbag assembly 5 is arranged on the catheter body 1, and the airbag assembly 5 is used to expand and fix the catheter body 1 in the bladder.

[0060] Specifically, the airbag assembly 5 is arranged on the catheter body 1, and the airbag assembly 5 will be placed into the patient's bladder together with the end of the catheter body. Then, gas or liquid (usually sterile water) is introduced into the airbag assembly 5, and the airbag assembly 5 will be filled. The filled airbag assembly 5 can be stuck in the bladder, thereby preventing the catheter body 1 from accidentally slipping out of the patient's urethra, thus playing a good fixing role and enabling the urinary catheter for detecting urinary tract infection conditions to maintain a relatively stable position during use, facilitating continuous urine drainage and other related operations.

[0061] Such as Figure 1As shown in the figure, the balloon assembly 5 includes a balloon 51 and a ventilation tube 52. The balloon 51 is disposed on the urinary catheter body 1 and is arranged near one end of the urinary catheter body 1 inserted into the bladder; a ventilation duct is formed inside the ventilation tube 52. One end of the ventilation duct is connected to the balloon 51, the inner cavity of the balloon 51 is communicated with the ventilation duct, and the other end of the ventilation duct is used for injecting gas or liquid into the ventilation duct.

[0062] Specifically, the balloon 51 is in the shape of a circular loop. The balloon 51 is disposed on the outer periphery of the urinary catheter body 1 and is arranged near one end of the urinary catheter body 1 inserted into the patient's bladder. The balloon 51 can be inserted into the bladder together with the urinary catheter body 1.

[0063] One end of the ventilation tube 52 is disposed on the balloon 51, and the other end is provided with a ventilation port. The ventilation port is arranged near the detection tube 3 and the urinary catheter 2. The ventilation port, the urinary catheter 2, and the detection tube 3 are all disposed on the same side of the urinary catheter body 1.

[0064] The ventilation port can be connected to an external filling device to introduce gas or liquid into the balloon 51 to make the balloon 51 inflated. The inflated balloon 51 can be stuck in the bladder, thereby preventing the urinary catheter body 1 from accidentally slipping out of the patient's urethra, thus playing a good fixing role, enabling the urinary catheter for detecting urinary tract infections to maintain a relatively stable position during use, and facilitating continuous urine drainage and other related operations.

[0065] The ventilation tube 52 is independent of the urinary catheter 2, and the ventilation tube 52 is independent of the detection tube 3. It should be noted that the ventilation tube 52 can be independent of the urinary catheter body 1 or part of the ventilation tube 52 can be included in the urinary catheter body 1.

[0066] That is, the ventilation tube 52 can be independent of the urinary catheter body 1. The ventilation tube 52 is located outside the urinary catheter body 1, and one end of the ventilation tube 52 is directly connected to the balloon 51.

[0067] Alternatively, part of the ventilation tube 52 is disposed inside the urinary catheter body 1, that is, there is not only the first urine drainage pipeline but also a ventilation duct inside the urinary catheter body 1.

[0068] One end of the ventilation tube 52 near the balloon 51 extends out of the urinary catheter body 1 to communicate with the balloon 51 or the balloon 51 is directly communicated with the ventilation duct.

[0069] Such as Figure 3As shown, a detection method for a urinary catheter for detecting urinary tract infection conditions is applied to any of the urinary catheters for detecting urinary tract infection conditions described above. The urinary catheter for detecting urinary tract infection conditions includes a detection tube body 31 and a pipeline conduction control member 33. One end of the detection tube body 31 is provided on the urinary catheter body 1, and the pipeline conduction control member 33 is provided at the other end of the detection tube body 31. A detection pipeline is formed inside the detection tube body 31, and the pipeline conduction control member 33 is used to control the conduction or closing of the detection pipeline. The detection member 4 is connected to the pipeline conduction control member 33.

[0070] The detection tube body 31, the one-way check member 32, and the pipeline conduction control member 33 are detachably connected to each other, such as by screwing. The detachable connection between the detection tube body 31, the one-way check member 32, and the pipeline conduction control member 33 facilitates the replacement of the one-way check member 32 and the pipeline conduction control member 33 and the adjustment of the connection sequence of the pipeline conduction control member 33 and the one-way check member 32 as needed.

[0071] The method includes:

[0072] S100. Open the pipeline conduction control member 33 to control the communication between the detection pipeline and the storage space.

[0073] Specifically, the pipeline conduction control member 33 is a throttle valve. Opening the pipeline conduction control member 33 makes the detection pipeline communicate with the storage space, which is convenient for the urine to be detected to flow smoothly from the detection pipeline into the storage space and mix with the detection reagent.

[0074] After controlling the communication between the detection pipeline and the storage space, the pipeline conduction control member 33 can be adjusted to adjust the flow area size to control the flow rate of the urine in the detection pipeline flowing into the storage space.

[0075] After the patient urinates, the urine to be detected will flow into the first ureteral catheter. Then, part of the urine to be detected will be discharged from the second ureteral catheter. At the same time, another part of the urine to be detected will flow into the detection pipeline and finally flow into the storage space to mix with the detection reagent.

[0076] During the process of the urine to be detected flowing into the storage space, the pipeline conduction control member 33 can also be adjusted at any time to adjust the flow area size and control the flow rate of the urine to be detected entering the storage space.

[0077] Before step S100, there is also a step:

[0078] S10. Perform detection pre-preparation.

[0079] Specifically, performing detection pre-preparation includes steps:

[0080] T100. Determine the connection sequence of the pipeline conduction control part 33 and the one-way check part 32 as needed, and make the connection.

[0081] T200. Fill the storage space with the detection reagent and install the filled detection part 4 on the detection tube 3.

[0082] T300. Insert one end of the urine catheter body 1, which is far from the urinary catheter 2 and the detection tube 3, into the patient's bladder.

[0083] T400. Pass gas or liquid into the airbag 51 through the vent until the airbag 51 is filled and stuck in the bladder.

[0084] S200. Detect the color reaction of the detection reagent and close the pipeline conduction control part 33.

[0085] During the process of catheterization of the patient by the operator, the operator can record the color change of the detection reagent at any time by taking pictures or videos of the detection part 4 in real time, using a color discrimination instrument such as a color difference meter, or directly observing with the naked eye, so as to judge whether the patient has urinary tract infection. When the detection reagent has a color reaction or the solution in the storage part reaches the critical liquid level (the critical liquid level refers to the highest liquid level of the solution stored in the preset storage space to prevent the solution from spilling out of the storage space when the detection part 4 is removed from the detection part 4), close the pipeline conduction control part 33 and stop the detection of the urine to be detected.

[0086] In summary, a urine catheter for detecting urinary tract infection includes a urine catheter body 1, a urinary catheter 2, a detection tube 3 and a detection part 4. A first urine transmission pipeline is formed in the urine catheter body 1; the urinary catheter 2 is arranged at one end of the urine catheter body 1, and a second urine transmission pipeline is formed in the urinary catheter 2, and the second urine transmission pipeline is communicated with the first urine transmission pipeline; one end of the detection tube 3 is arranged on the urine catheter body 1, a detection pipeline is formed in the detection tube 3, and the detection pipeline is communicated with the first urine transmission pipeline; the detection part 4 is arranged at the other end of the detection tube 3, a storage space is formed in the detection part 4, a detection reagent is stored in the storage space, the detection reagent is used for reacting with the infected urine to produce a color reaction, and the storage space is communicated with the detection pipeline.

[0087] When the patient urinates, while the urine is discharged from the urinary catheter 2, part of the urine will flow into the detection pipeline and finally into the detection part 4. The urine discharged by the patient will be mixed with the detection reagent. If the patient's urine is infected, the infected urine will react with the detection reagent and the detection reagent will change color. Therefore, medical staff can predict whether the patient has urinary tract infection by whether the detection reagent changes color, solving the problem that the existing infection detection method has hysteresis and cannot understand the patient's infection situation during the catheterization process of the patient.

[0088] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0089] It should be noted that the present invention takes a urinary catheter and a detection method for detecting urinary tract infection as an example to introduce the specific structure and working principle of the present invention. However, the application of the present invention is not limited to a urinary catheter and a detection method for detecting urinary tract infection, and can also be applied to the production and use of other similar workpieces.

[0090] It should be understood that the present invention is not limited to the exact structure already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.

[0091] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
