Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and more particularly, to a urinary catheter for urine culture collection. Background Art
[0002] In clinical medical work, bedridden patients need to collect midstream urine. However, due to their own reasons, such as being unable to speak or having fecal and urinary incontinence, they are unable to collect midstream urine. Medical staff will use a urinary catheter to catheterize and then use a sterile container to collect the urine specimen and then remove the catheter.
[0003] Currently, during the collection process, the catheterization port of the urinary catheter in use will directly flow out of the catheter, which is likely to contaminate the bed unit, cause discomfort to the patient, and is not convenient for changing the bedsheet. At the same time, it is also likely to contaminate the specimen and the surrounding environment.
[0004] In view of the above problems, there is an urgent need for improvement. Summary of the Utility Model
[0005] The purpose of the present application is to provide a urinary catheter for urine culture collection, which has the advantages of convenient specimen collection and reduced specimen contamination rate.
[0006] The present application provides a urinary catheter for urine culture collection, and the technical solution is as follows:
[0007] It includes a catheter body, and a first channel and a second channel are axially communicated in the catheter body. The catheter body is inserted into the patient's urethra. The first channel at the head of the catheter body is connected to the patient's bladder, and the first channel at the tail of the catheter body is connected to a collector; an airbag is provided on the outer wall of the head of the catheter body. One end of the second channel is communicated with the airbag, and the other end of the second channel is connected to an inflation assembly. After the airbag is inflated, it abuts against the inner wall of the patient's bladder.
[0008] The urine culture catheter provided by the present application includes a catheter body. The catheter body is axially provided with a first channel and a second channel in communication. The catheter body is inserted into the patient's urethra. The first channel at the head of the catheter body is connected to the patient's bladder, and the first channel at the tail of the catheter body is connected to a collector. Among them, the first channel is used to drain sterile urine and cooperate with the collector to collect urine, so as to obtain midstream urine for urine culture to check whether there is pathogen infection and help with drug sensitivity tests. An airbag is provided on the outer wall of the head of the catheter body. One end of the second channel is connected to the airbag in communication, and the other end of the second channel is connected to an inflation assembly. After the airbag is inflated, it abuts against the inner wall of the patient's bladder. Through the setting of the above structure, when the head of the catheter body enters the bladder from the patient's urethra, the uninflated airbag provided on the outer wall of the head of the catheter body also enters and is located in the bladder. The inflation assembly inflates the airbag through the second channel. When the airbag expands, while being located inside the bladder, the airbag can also abut against the urethra to play a limiting role and prevent the catheter body from slipping out, thus creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced. When the collection of midstream urine is completed, the air in the airbag is pumped out through the second channel. After the airbag fits the catheter body, the catheter body is taken out along the urethra, thereby completing the operation.
[0009] Further, in the present application, a water injection soft valve is provided at the end of the second channel away from the airbag, and the water injection soft valve is connected to the inflation assembly.
[0010] For the urine culture catheter provided by the present application, a water injection soft valve is provided at the end of the second channel away from the airbag, and the water injection soft valve is connected to the inflation assembly. Among them, the water injection soft valve is used to control the gas flow rate. When inflating the airbag, it helps the gas to smoothly enter the airbag through the second channel, prevents the gas from discharging from the airbag, and avoids gas backflow, so that the airbag obtains a sufficient inflation effect. Furthermore, while being located inside the bladder, the airbag can also abut against the urethra to play a limiting role and prevent the catheter body from slipping out, creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced.
[0011] Further, in the present application, the outer wall of the airbag is a smooth surface.
[0012] For the urine culture catheter provided by the present application, the outer wall of the airbag is a smooth surface, which is used to achieve a smooth contact effect, ensure that the airbag passes through the patient's urethra and enters the bladder synchronously and smoothly with the catheter body before inflation, and avoid excessive resistance when the airbag passes through the urethra. When the airbag is inflated, the airbag still maintains a smooth contact effect, plays a limiting role on the catheter body inside the bladder to prevent the catheter body from slipping out, and at the same time reduces the frictional force generated by the airbag on the urethra or bladder, ensuring that the patient's urethra and bladder are not damaged.
[0013] Furthermore, in the present application, the shape of the balloon after inflation is spherical.
[0014] For the urine culture catheter provided by the present application, the shape of the balloon after inflation is spherical. With the above structure, after the balloon is inflated, the spherical balloon can play a more comprehensive and stable limiting role inside the patient's bladder, prevent the catheter body from slipping out, create a stable and reliable working environment, and reduce the specimen contamination rate while safely and conveniently collecting urine specimens.
[0015] Furthermore, in the present application, there is a distance between the balloon and the free end of the head of the catheter body.
[0016] Furthermore, in the present application, the size of the balloon after inflation is larger than the size of the patient's urethra.
[0017] Furthermore, in the present application, the length of the catheter body is 15 - 20 cm.
[0018] Furthermore, in the present application, the catheter body is made of transparent silicone material.
[0019] Furthermore, in the present application, scale values are marked on the axial outer wall of the catheter body.
[0020] Furthermore, in the present application, an open lid is provided at one - end switch of the first channel located at the tail of the catheter body.
[0021] As can be seen from the above, a urine culture catheter provided by the present application includes a catheter body. The catheter body is axially provided with a first channel and a second channel in communication. The catheter body is inserted into the urethra of a patient. The first channel at the head of the catheter body is connected to the bladder of the patient, and the first channel at the tail of the catheter body is connected to a collector. Among them, the first channel is used to drain sterile urine and cooperate with the collector to collect urine, so as to obtain midstream urine for urine culture to check whether there is pathogen infection and help with drug sensitivity tests. An airbag is provided on the outer wall of the head of the catheter body. One end of the second channel is connected to the airbag in communication, and the other end of the second channel is connected to an inflation component. After the airbag is inflated, it abuts against the inner wall of the bladder of the patient. Through the setting of the above structure, when the head of the catheter body enters the bladder from the urethra of the patient, the uninflated airbag provided on the outer wall of the head of the catheter body also enters and is located in the bladder accordingly. The inflation component inflates the airbag through the second channel. When the airbag expands, while being located inside the bladder, the airbag can also abut against the urethra to play a limiting role and prevent the catheter body from slipping out, thereby creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced. After the midstream urine collection is completed, the air in the airbag is pumped out through the second channel. After the airbag fits the catheter body, the catheter body is taken out along the urethra, thus completing the operation. A water injection soft valve is provided at one end of the second channel away from the airbag. The water injection soft valve is connected to the inflation component. Among them, the water injection soft valve is used to control the gas flow rate. When inflating the airbag, it helps the gas to smoothly enter the inside of the airbag through the second channel, prevents the gas from discharging from the inside of the airbag, and avoids gas backflow, so that the airbag can obtain a sufficient inflation effect. Furthermore, while being located inside the bladder, the airbag can also abut against the urethra to play a limiting role and prevent the catheter body from slipping out, creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced. The outer wall of the airbag is a smooth surface, which is used to achieve a smooth contact effect, ensure that the airbag passes through the urethra of the patient synchronously and smoothly with the catheter body and enters the bladder before inflation, and avoid excessive resistance when the airbag passes through the urethra. After the airbag is inflated, the airbag still maintains a smooth contact effect. While playing a limiting role inside the bladder to prevent the catheter body from slipping out, it reduces the frictional force exerted by the airbag on the urethra or the bladder, ensuring that the urethra and bladder of the patient are not damaged. The shape of the airbag after inflation is spherical. Through the above structure, after the airbag is inflated, the spherical airbag can play a more comprehensive and stable limiting role inside the bladder of the patient, prevent the catheter body from slipping out, create a stable and reliable working environment, and reduce the specimen contamination rate while safely and conveniently collecting urine specimens.

[0027] The technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.
[0028] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0029] Please refer to Figures 1 to 3 As shown, the present application provides a urine culture catheter, including a catheter body 1. The catheter body 1 is axially provided with a first channel 2 and a second channel 3 in communication. The catheter body 1 is inserted into the urethra of a patient. The first channel 2 at the head of the catheter body 1 is connected to the patient's bladder, and the first channel 2 at the tail of the catheter body 1 is connected to a collector; an airbag 4 is provided on the outer wall of the head of the catheter body 1. One end of the second channel 3 is in communication connection with the airbag 4, and the other end of the second channel 3 is connected to an inflation assembly. After the airbag 4 is inflated, it abuts against the inner wall of the patient's bladder.
[0030] Specifically, in the clinical work of medicine, bedridden patients need to collect midstream urine. However, due to their own reasons, such as being unable to speak or having fecal and urinary incontinence, they are unable to collect midstream urine. Medical staff will use a urinary catheter to drain urine and then use a sterile container to collect the urine specimen and then remove the catheter. At present, the urinary catheterization port of the urinary catheter used will directly flow out of the catheter during the collection process, which is easy to contaminate the bed unit, cause discomfort to the patient, and is not convenient for changing the bedsheet. At the same time, it is easy to contaminate the specimen and the surrounding environment. Therefore, to solve the above problems, the urine culture urinary catheter provided in this application includes a catheter body 1. The catheter body 1 is axially provided with a first channel 2 and a second channel 3 in communication. The catheter body 1 is inserted into the patient's urethra. The first channel 2 at the head of the catheter body 1 is connected to the patient's bladder, and the first channel 2 at the tail of the catheter body 1 is connected to a collector; wherein, the first channel 2 is used to drain sterile urine and cooperate with the collector to collect urine, so as to obtain midstream urine for urine culture to check whether there is a pathogen infection and help with drug sensitivity tests. An airbag 4 is provided on the outer wall of the head of the catheter body 1. One end of the second channel 3 is connected to the airbag 4 in communication, and the other end of the second channel 3 is connected to an inflation assembly. After the airbag 4 is inflated, it abuts against the inner wall of the patient's bladder. Through the setting of the above structure, when the head of the catheter body 1 enters the bladder from the patient's urethra, the uninflated airbag 4 provided on the outer wall of the head of the catheter body 1 also enters and is located in the bladder. The inflation assembly inflates the airbag 4 through the second channel 3. When the airbag 4 expands, the airbag 4 can abut against the urethra while being located inside the bladder, playing a limiting role to prevent the catheter body 1 from slipping out, thereby creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced. When the collection of midstream urine is completed, the air in the airbag 4 is pumped out through the second channel 3. After the airbag 4 fits the catheter body 1, the catheter body 1 is removed along the urethra, thus completing the operation.
[0031] In some preferred embodiments, a water injection soft valve 5 is provided at the end of the second channel 3 away from the airbag 4, and the water injection soft valve 5 is connected to the inflation assembly.
[0032] Specifically, a water injection soft valve 5 is provided at the end of the second channel 3 away from the airbag 4, and the water injection soft valve 5 is connected to the inflation assembly. Among them, the water injection soft valve 5 is used to control the gas flow rate. When inflating the airbag 4, it helps the gas to smoothly enter the inside of the airbag 4 through the second channel 3, preventing the gas from discharging from the inside of the airbag 4 and avoiding gas backflow, so that the airbag 4 obtains a sufficient expansion effect. Furthermore, the airbag 4 can abut against the urethra while being located inside the bladder, playing a limiting role to prevent the catheter body 1 from slipping out, creating a stable and reliable working environment. While safely and conveniently collecting urine specimens, the specimen contamination rate is reduced.
[0033] In some preferred embodiments, the outer wall of the airbag 4 is a smooth surface.
[0034] Specifically, the outer wall of the airbag 4 is a smooth surface, which is used to achieve a smooth contact effect, ensuring that the airbag 4 passes through the patient's urethra and enters the bladder synchronously and smoothly with the catheter body 1 before inflation, avoiding excessive resistance when the airbag 4 passes through the urethra. When the airbag 4 is inflated, the airbag 4 still maintains a smooth contact effect, and limits the catheter body 1 inside the bladder, preventing the catheter body 1 from falling out, while reducing the friction force generated by the airbag 4 on the urethra or bladder, ensuring that the patient's urethra and bladder are not damaged.
[0035] In some preferred embodiments, the shape of the airbag 4 after being inflated is spherical.
[0036] Specifically, the shape of the airbag 4 after being inflated is spherical. Through the above structure, after the airbag 4 is inflated, the spherical airbag 4 can play a more comprehensive and stable limiting role inside the patient's bladder, preventing the catheter body 1 from falling out, creating a stable and reliable working environment, and reducing the specimen contamination rate while safely and conveniently collecting urine specimens.
[0037] In some preferred embodiments, a distance is left between the balloon 4 and the free end of the head of the catheter body 1 .
[0038] Specifically, in order to enable the first channel 2 located at the head of the catheter body 1 to smoothly drain and collect urine inside the bladder, in this embodiment, a distance is left between the airbag 4 and the free end of the head of the catheter body 1. Through the arrangement of the above structure, when the first channel 2 located at the head of the catheter body 1 reaches the patient's bladder, the airbag 4, after being inflated, still leaves a distance from the free end of the first channel 2 located at the head of the catheter body 1. The free end of the first channel 2 located at the head of the catheter body 1 can drain and collect urine in the bladder, and then obtain a urine specimen, thereby preventing interference between the airbag 4 and the free end of the first channel 2 located at the head of the catheter body 1. In addition, the inflated airbag 4 plays a more comprehensive and stable limiting role inside the patient's bladder, preventing the catheter body 1 from falling out, creating a stable and reliable working environment, and reducing the specimen contamination rate while safely and conveniently retaining urine specimens.
[0039] In some preferred embodiments, the size of the balloon 4 after inflation is larger than the size of the patient's urethra.
[0040] Specifically, to ensure that the airbag 4 has a good limiting effect after inflation, in this embodiment, the size of the airbag 4 after inflation is larger than the size of the patient's urethra. When the airbag 4 reaches the patient's bladder along with the catheter body 1, the inflation assembly inflates the airbag 4 through the first channel 2. When the airbag 4 inflates and expands, it plays a limiting role on the catheter body 1 in the patient's bladder, preventing the catheter body 1 from slipping out of the urethra, creating a stable and reliable working environment, thereby reducing the specimen contamination rate while safely and conveniently collecting urine specimens.
[0041] In some preferred embodiments, the length of the catheter body 1 is 15 - 20 cm.
[0042] Specifically, the length of the male urethra is usually 15 - 20 cm, and the length of the female urethra is usually 4 - 6 cm. To make the catheter body 1 have a reasonable length and ensure its adaptation to the patient's urine collection needs, in this embodiment, the length of the catheter body 1 is 15 - 20 cm. Through the above structure setting, the catheter body 1 not only adapts to the needs of obtaining urine specimens from males but also to the needs of obtaining urine specimens from females. As one implementation option, the length of the catheter body 1 can also be set to 4 - 6 cm, that is, the catheter body 1 with a length of 15 - 20 cm is used for the operation of obtaining urine specimens from males, and the catheter body 1 with a length of 4 - 6 cm is used for the operation of obtaining urine specimens from females, thereby realizing differential use and enhancing the convenience and accuracy of the catheter body 1 when obtaining urine specimens from patients.
[0043] In some preferred embodiments, the catheter body 1 is made of transparent silicone material.
[0044] Specifically, to facilitate the observation of the urine drainage situation after the first channel 2 of the catheter body 1 drains urine, in this embodiment, the catheter body 1 is made of transparent silicone material. Through the above structure setting, when urine is drained and collected through the first channel 2 of the catheter body 1, the flow condition of urine in the first channel 2 can be clearly observed through the catheter body 1, ensuring the accuracy of collecting the patient's urine specimen, cooperating with the airbag 4 to play a limiting role and a urine collection role, thereby reducing the specimen contamination rate while safely and conveniently collecting urine specimens.
[0045] In some preferred embodiments, scale values are marked on the axial outer wall of the catheter body 1.
[0046] Specifically, to facilitate the accurate observation and control of the urine specimen collection volume and ensure the acquisition of a reasonable and accurate urine specimen, in this embodiment, scale values are marked on the axial outer wall of the catheter body 1. By observing the scale values, the urine is controlled within the target collection volume, thereby accurately obtaining the midstream urine specimen of the patient, thereby reducing the specimen contamination rate while safely and conveniently collecting urine specimens.
[0047] In some preferred embodiments, an opening cover 6 is provided at one end switch of the first channel 2 located at the tail of the catheter body 1.
[0048] Specifically, in order to facilitate the controlled collection of the drained urine, in this embodiment, an opening cover 6 is provided at one end switch of the first channel 2 located at the tail of the catheter body 1. Through the above structure, when it is confirmed that there is urine in the first channel 2 of the catheter body 1, the opening cover 6 is opened to collect the urine, that is, the urine discharged from the free end of the first channel 2 located at the tail of the catheter body 1 is collected by the collector, thereby obtaining the midstream urine specimen of the patient. Thus, while safely and conveniently collecting the urine specimen, the specimen contamination rate is reduced.
[0049] In some preferred embodiments, the outer wall of the free end of the head of the catheter body 1 is a smooth arc structure.
[0050] Specifically, in order to enable the catheter body 1 to smoothly pass through the patient's urethra and enter the bladder, in this embodiment, the outer wall of the free end of the head of the catheter body 1 is a smooth arc structure. Through the above structure, the free end of the head of the catheter body 1 can smoothly enter along the patient's urethra, playing a good guiding role, and then reaching the patient's bladder, realizing the collection and acquisition of midstream urine. Thus, while safely and conveniently collecting the urine specimen, the specimen contamination rate is reduced.
[0051] Through the above technical solutions, the urine culture catheter provided by the present application includes a catheter body 1. The catheter body 1 is axially provided with a first channel 2 and a second channel 3 in communication. The catheter body 1 is inserted into the urethra of a patient. The first channel 2 at the head of the catheter body 1 is connected to the patient's bladder, and the first channel 2 at the tail of the catheter body 1 is connected to a collector. Among them, the first channel 2 is used to drain sterile urine and cooperate with the collector to collect urine, so as to obtain midstream urine for urine culture to check whether there is pathogen infection and help with drug sensitivity tests. An airbag 4 is provided on the outer wall of the head of the catheter body 1. One end of the second channel 3 is connected to the airbag 4 in communication, and the other end of the second channel 3 is connected to an inflation assembly. After the airbag 4 is inflated, it abuts against the inner wall of the patient's bladder. Through the setting of the above structure, when the head of the catheter body 1 enters the bladder from the urethra of the patient, the uninflated airbag 4 provided on the outer wall of the head of the catheter body 1 also enters and is located in the bladder. The inflation assembly inflates the airbag 4 through the second channel 3. When the airbag 4 expands, the airbag 4 can abut against the urethra while being located inside the bladder, playing a limiting role to prevent the catheter body 1 from slipping out, thereby creating a stable and reliable working environment, reducing the specimen contamination rate while safely and conveniently collecting urine specimens. When the collection of midstream urine is completed, the air in the airbag 4 is pumped out through the second channel 3. After the airbag 4 fits the catheter body 1, the catheter body 1 is taken out along the urethra, thus completing the operation. A water injection soft valve 5 is provided at the end of the second channel 3 away from the airbag 4. The water injection soft valve 5 is connected to the inflation assembly. Among them, the water injection soft valve 5 is used to control the gas flow rate. When inflating the airbag 4, it helps the gas to smoothly enter the inside of the airbag 4 through the second channel 3, preventing the gas from discharging from the inside of the airbag 4 and avoiding gas backflow, so that the airbag 4 can obtain a sufficient inflation effect. Furthermore, the airbag 4 can abut against the urethra while being located inside the bladder, playing a limiting role to prevent the catheter body 1 from slipping out, creating a stable and reliable working environment, reducing the specimen contamination rate while safely and conveniently collecting urine specimens. The outer wall of the airbag 4 is a smooth surface, which is used to achieve a smooth contact effect, ensuring that the airbag 4 synchronously and smoothly passes through the patient's urethra and enters the bladder together with the catheter body 1 before inflation, and avoiding excessive resistance when the airbag 4 passes through the urethra. When the airbag 4 is inflated, the airbag 4 still maintains a smooth contact effect. While playing a limiting role to prevent the catheter body 1 from slipping out inside the bladder, it reduces the frictional force exerted by the airbag 4 on the urethra or bladder, ensuring that the patient's urethra and bladder are not damaged. The shape of the airbag 4 after inflation is spherical. Through the above structure, after the airbag 4 is inflated, the spherical airbag 4 can play a more comprehensive and stable limiting role inside the patient's bladder, preventing the catheter body 1 from slipping out, creating a stable and reliable working environment, reducing the specimen contamination rate while safely and conveniently collecting urine specimens.
[0052] The above are only embodiments of the present application and are not intended to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
