Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a urine sampling device for nephrology nursing care. Background Technology

[0002] Urine sampling in nephrology is a common medical examination used to assess a person's health status. It can provide information about kidney function, urinary tract infections, metabolic diseases, and many other health issues.

[0003] When collecting urine samples from patients, a urine sampling device is required. However, for bedridden or immobile patients, existing urine sampling devices have poor fit, failing to fit tightly against the patient's urethra. This leads to urine leakage during sampling, which not only contaminates the bed but also contaminates medical staff, making the urine sampling process difficult and reducing the efficiency of medical staff. Therefore, this invention provides a urine sampling device for nephrology nursing to solve the above problems. Summary of the Invention

A third airbag is installed on one side of the rectangular urine collection head. A second flexible tube is installed at the air inlet end of the third airbag. A guide plate is fixedly connected to the inner wall of the rectangular urine collection head and below the outlet.

[0010] Optionally, the auxiliary component includes two circular seats fixedly connected to the top of the handle. A first airbag is installed on the inner side of each of the two circular seats. A preset air passage is installed in each of the two connecting ports of the first airbag. One end of each of the two preset air passages extends through to the outside of the circular seat and is fixedly connected to a first one-way valve and a second one-way valve, respectively. A first hose is installed at the air outlet of the second one-way valve. A sealing plug is fixedly connected to one end of one of the first hoses, and a threaded connector is rotatably connected to one end of the other first hose. A second threaded connection channel matching the threaded connector is fixedly connected to the inner side of the urine collection cylinder.

[0011] Optionally, a first sealing gasket is fixedly connected to the outer wall of the sealing plug, and the outer diameter of the sealing plug is smaller than the inner diameter of the second hose and the auxiliary hose.

[0012] Optionally, the first check valve connected to the sealing plug is an input valve and the second check valve is an output valve, while the first check valve connected to the threaded connector is an output valve and the second check valve is an input valve.

[0013] Optionally, the sampling unit includes an air supply chamber located inside the handle, with both ends of the air supply chamber extending through to the top and bottom of the handle, a push rod provided on the inner side of the air supply chamber, one end of the push rod extending to the outside of the handle, and the outer wall of the push rod being threaded, and a threaded seat fixedly connected to the inner side of the air supply chamber, with the push rod being threadedly connected to the threaded seat.

[0016] Optionally, the inner side of the urine collection cylinder is provided with a rectangular channel that matches the baffle, and the outer wall of the baffle is equipped with a second sealing gasket for sealing the rectangular channel.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up components such as the first threaded connection channel, when sampling male patients, the airbag inflates and flexibly and tightly wraps and seals the outer wall of the penis, adapting to different penile shapes and sizes. The airbag inflation degree can be adjusted while taking into account the comfort of the body, forming a leak-free, sealed urine collection area. When sampling female patients, the airbag inflates and fits against the groin, positioning the urethra at the center of the rectangular urine collection head to form a sealed urine collection space. With the guide plate's inclined surface guiding, the urine flows smoothly, adapting to the physiological structure characteristics of women, solving the problems of external leakage and incomplete collection, improving the sampling success rate and cleanliness, and effectively improving the device's adaptability to the urethra of male and female patients.

[0019] By using components such as the first airbag, the system can assist in the smooth and complete collection of urine on the basis of the patient's natural urination, without the patient having to deliberately exert force to urinate or adjust their posture, thus improving the patient's urination comfort. Furthermore, the flexible airbag's fit and non-compression design can ensure the sealing effect of the sampling while reducing the discomfort caused by the patient's pain sensitivity, thereby reducing the difficulty of the urine sampling process and improving the work efficiency of medical staff.

[0020] By setting up a sampling unit, after the patient expels the initial urine, medical staff can rotate the push rod to precisely close the baffle inside the urine collection cylinder. The baffle is then sealed by a second sealing gasket, completely isolating the initial urine at the bottom of the collection cylinder and collecting the midstream urine that meets clinical testing standards. This avoids detection deviations caused by contamination from impurities in the initial urine, ensuring the accuracy and effectiveness of urine sample testing, thereby improving the work efficiency of medical staff.

A first threaded connection channel 4 is provided at the inlet of the urine collection cylinder 2, and a sampling connector is located on one side of the first threaded connection channel 4. The sampling connector includes a male sampling connector, a female sampling connector, and auxiliary components, used for collecting patient urine.

[0040] like Figure 4 and Figure 5 As shown, the male sampling connector includes a first fixed threaded channel 11 disposed on one side of the urine collection cylinder 2. The outer wall of the first fixed threaded channel 11 is rotatably connected to two first fixed seats 12 via a first damping shaft. A circular urine collection head 13 is fixedly connected to one end of each of the two first fixed seats 12. A fifth hose 32 is installed between the inlet of the first fixed threaded channel 11 and the outlet of the circular urine collection head 13. A third one-way valve 34 is fixedly connected to the inner side of the circular urine collection head 13. A second airbag 15 is installed on the inner side of the second inlet of the circular urine collection head 13. An auxiliary hose 16 is installed at the air inlet end of the second airbag 15.

[0041] For example Figure 4 and Figure 6As shown, the female sampling connector also includes a third threaded connection channel 17 disposed on one side of the urine collection cylinder 2. Two second fixed seats 18 are rotatably connected to the outer wall of the third threaded connection channel 17 via a second damping mechanism. A rectangular urine collection head 14 is fixedly connected to one end of each of the two second fixed seats 18. A fourth one-way valve 35 is fixedly connected to the inner side of the third threaded connection channel 17. A fourth flexible tube 31 is installed between the inlet of the third threaded connection channel 17 and the outlet of the rectangular urine collection head 14. A third airbag 20 is installed on one side of the rectangular urine collection head 14. The second flexible tube 21 is installed at the air inlet end of the third airbag 20. A guide plate 19 is fixedly connected to the inner wall of the rectangular urine collection head 14, located below the outlet.

[0042] like Figure 7 and Figure 9 As shown, the sampling connector includes an auxiliary component located at the top of the handle 1. The auxiliary component includes two circular seats 6 fixedly connected to the top of the handle 1. A first airbag 7 is installed inside each of the two circular seats 6. Each of the two connecting ports of the first airbag 7 has a preset air passage installed. One end of each preset air passage extends through to the outside of the circular seat 6 and is fixedly connected to a first one-way valve 22 and a second one-way valve 33, respectively. A first hose 8 is installed at the air outlet of the second one-way valve 33. A sealing plug 9 is fixedly connected to one end of one first hose 8, and a threaded connector 10 is rotatably connected to one end of the other first hose 8. A second threaded connection channel 5 matching the threaded connector 10 is fixedly connected to the inner side of the urine collection cylinder 2. A first sealing gasket is fixedly connected to the outer wall of the sealing plug 9, and the outer diameter of the sealing plug 9 is smaller than the inner diameter of the second hose 21 and the auxiliary hose 16. The first one-way valve 22 connected to the sealing plug 9 is an input valve, and the second one-way valve 33 is an output valve. The first one-way valve 22 connected to the threaded connector 10 is an output valve, and the second one-way valve 33 is an input valve. Specifically, a rubber pad is provided at the contact point between the second threaded connection channel 5 and the threaded connector 10. The end of the sealing plug 9 is tapered, and a rubber pad is provided on the outer wall of the sealing plug 9. The first fixed threaded channel 11, the first fixed seat 12, the circular urine collection head 13, the second airbag 15, the auxiliary hose 16, the fifth hose 32, and the third one-way valve 34 form a disposable male urine sampling head, and the rectangular urine collection head 14, the third threaded connection channel 17, the guide plate 19, the third airbag 20, the second hose 21, the fourth hose 31, and the fourth one-way valve 35 form a disposable female urine sampling head. These two samplers are collectively referred to as urine sampling heads. A rubber pad is provided at the contact point between the first threaded connection channel 4 and the first fixed threaded channel 11 and the third threaded connection channel 17.

[0043] The process of using the urine sampling device for nephrology nursing in this embodiment to sample urine from male patients is as follows:

[0044] Medical staff can remove a disposable male urine sampler and thread it to fix the first fixed threaded channel 11 to the first threaded connection channel 4.

[0045] After the fixing is completed, insert the sealing plug 9 into the auxiliary hose 16 so that it is sealed and connected to the auxiliary hose 16 through the first sealing gasket, and then fix the threaded connector 10 to the second threaded connection channel 5 by thread.

[0046] By holding handle 1 and inserting the patient's penis into the circular urine collection head 13, the medical staff can rotate the circular urine collection head 13 according to the direction of the penis to adjust the angle of the circular urine collection head 13. After adjustment, the medical staff can press one of the first airbags 7 to allow air to enter the second airbag 15 from the first tubing 8 through the auxiliary tubing 16, causing it to inflate. When the first airbag 7 is released, the first airbag 7 rebounds and draws in external air through the first one-way valve 22. By repeatedly pressing the first airbag 7, the medical staff can make the second airbag 15 wrap around the patient's penis and fit against its outer wall. The degree of inflation of the second airbag 15 is adjusted according to the patient's comfort until the patient stops, and the medical staff no longer presses the first airbag 7.

[0047] Medical staff can instruct the patient to urinate. At this time, urine enters the circular urine collection head 13. The medical staff can then press another first airbag 7. At this time, the gas inside the second threaded connection channel 5 is discharged from the first one-way valve 22. When the first airbag 7 rebounds, it draws the gas inside the second threaded connection channel 5 into the first flexible tube 8 through the threaded connector 10, and then into the first airbag 7 through the second one-way valve 33. This creates negative pressure inside the second threaded connection channel 5, forcing the urine inside the circular urine collection head 13 to pass through the third one-way valve 34 and the fourth flexible tube 31 into the first fixed threaded channel 11, and finally into the urine collection cylinder 2. Through the coordinated operation of these structures, the angle-adjustable circular urine collection head 13 can be precisely fitted into the patient's penis. The inflation of the airbag forms a tight and flexible seal around the outer wall of the penis, adapting to different penile sizes and shapes. The inflation degree of the airbag can be adjusted as needed to ensure patient comfort, creating a leak-free, sealed urine collection area, thereby improving the device's adaptability to the male patient's urethra.

[0048] The urine sampling device for nephrology nursing in this embodiment is used to sample urine from female patients.

[0049] The working process is as follows:

[0050] Medical staff can remove a disposable female urine sampler and thread it to fix the third threaded connection channel 17 to the first threaded connection channel 4.

[0051] After the fixing is completed, insert the sealing plug 9 into the second hose 21 so that it is sealed and connected to the second hose 21 through the first sealing gasket, and then fix the threaded connector 10 to the second threaded connection channel 5 by thread.

[0052] Medical staff can adjust the direction of the rectangular urine collection head 14 according to the patient's urethral position, and then align the rectangular urine collection head 14 with the patient's urethra. At this time, the medical staff repeats the above operation to press the first airbag 7, so that the gas enters the third airbag 20 through the second tubing 21 and inflates it. When the third airbag 20 is completely fitted between the groin and the urethra is in the center of the rectangular urine collection head 14, the medical staff stops pressing the first airbag 7.

[0053] The patient is instructed to urinate, while medical staff repeat the above procedure by pressing another first airbag 7. This allows urine to be guided through the inclined surface of the guide plate 19 into the fourth tubing 31, and then through the fourth one-way valve 35 into the third threaded connection channel 17, finally entering the urine collection cylinder 2. The adjustable rectangular urine collection head 14 is precisely aligned with the female urethra. After the airbag is inflated, it fits the patient's crotch, firmly positioning the urethra in the center of the rectangular urine collection head 14 to form a sealed urine collection space. This effectively prevents the urine collection head from shifting during sampling. Combined with the inclined guiding effect of the guide plate 19, the urine can be guided quickly and smoothly, perfectly adapting to the special physiological structure of women. This solves the problems of easy leakage and incomplete collection of female urine samples, greatly improving the success rate and cleanliness of female sampling, thereby improving the adaptability of the equipment to the female patient's urethra.

[0054] With the aforementioned structure and the combined effect of negative pressure suction and drainage, urine can be collected smoothly and completely by assisting the patient in urinating naturally. This eliminates the need for the patient to strain or adjust their posture, improving urination comfort. Furthermore, the flexible airbag's fit and non-compression design ensure a secure sampling seal while reducing discomfort caused by pain and sensitivity, thus simplifying the urine sampling process and improving the efficiency of medical staff.

[0055] like Figure 2 and Figure 3As shown, the sampling unit is located inside the urine collection cylinder 2 and is used to sample the patient's urine. The sampling unit includes an air delivery chamber 30 inside the handle 1, with both ends of the air delivery chamber 30 extending to the top and bottom of the handle 1, respectively. A push rod 23 is provided inside the air delivery chamber 30, with one end of the push rod 23 extending to the outside of the handle 1. The outer wall of the push rod 23 is threaded, and a threaded seat 28 is fixedly connected to the inside of the air delivery chamber 30. The push rod 23 is threadedly connected to the threaded seat 28. The sampling unit also includes a piston plate 29 rotatably connected to one end of the push rod 23. Two limiting sliders are fixedly connected to the outside of the piston plate 29. A limiting groove matching the limiting slider is provided inside the air delivery chamber 30, and the limiting slider is slidably connected to the air delivery chamber 30 through the limiting groove. The sampling unit also includes a baffle 25 rotatably connected to the inside of the urine collection cylinder 2. An arc-shaped air chamber 26 is provided on the inside of the urine collection cylinder 2. A third hose 24 is installed between the output end of the air supply chamber 30 and the input end of the arc-shaped air chamber 26. An arc-shaped piston rod 27 is slidably connected to the inside of the arc-shaped air chamber 26. One end of the arc-shaped piston rod 27 passes through the inside of the urine collection cylinder 2 and is fixedly connected to one side of the baffle 25. A rectangular channel matching the baffle 25 is provided on the inside of the urine collection cylinder 2. A second sealing gasket for sealing the rectangular channel is installed on the outer wall of the baffle 25. A rubber gasket is provided at the contact part between the urine collection cylinder 2 and the sealing cover 3.

[0056] After the initial urine of a male or female patient is discharged into the urine collection cylinder 2, the initial urine flows to the bottom of the urine collection cylinder 2. At this time, the medical staff rotates the push rod 23, which moves downward inside the gas delivery chamber 30 through the threaded connection with the threaded seat 28. This causes the piston plate 29 to move downward inside the gas delivery chamber 30. At this time, gas enters the arc-shaped gas chamber 26 through the third hose 24 by the push of the piston plate 29. The gas pushes the arc-shaped piston rod 27, which moves the baffle 25 inside the urine collection cylinder 2 until the piston plate 29 moves to the bottom of the gas delivery chamber 30. At this time, the baffle 25 is completely in contact with the inside of the urine collection cylinder 2, and then passes through the second... The sealing pad isolates the urine at the bottom of the urine collection cylinder 2, collecting the midstream urine. Through the cooperation of the above structure, medical staff can simply rotate the push rod 23 after the patient urinates the initial urine to drive the baffle 25 to rotate and close precisely inside the urine collection cylinder 2. Relying on the sealing effect of the second sealing pad, the initial urine at the bottom of the urine collection cylinder 2 is completely isolated, achieving accurate collection of midstream urine that meets clinical testing standards. This effectively avoids the problem of urine test result deviation caused by impurities and easy contamination in the initial urine, ensuring the accuracy and effectiveness of urine sample testing, thereby improving the work efficiency of medical staff.

[0057] After collection, medical staff remove the urine sampler, unscrew it, and then unscrew the sealing cap 3. They then put the collected midstream urine into the urine analyzer for testing. After that, the inside of the urine collection cylinder 2 is disinfected and cleaned for future use, thereby improving the overall usability of the equipment.

[0058] The working process provided by the technical solution of this invention is as follows;

[0059] A rubber pad is provided at the contact point between the second threaded connection channel 5 and the threaded connector 10.

[0060] The end of the sealing plug 9 is tapered, and a rubber pad is provided on the outer wall of the sealing plug 9;

[0061] The first fixed threaded channel 11, the first fixed seat 12, the circular urine collection head 13, the second airbag 15, the auxiliary hose 16, the fifth hose 32 and the third one-way valve 34 form a disposable male urine sampling head, and the rectangular urine collection head 14, the third threaded connection channel 17, the guide plate 19, the third airbag 20, the second hose 21, the fourth hose 31 and the fourth one-way valve 35 form a disposable female urine sampling head. These two samplers are collectively referred to as urine sampling heads.

[0062] Rubber pads are provided at the contact points between the first threaded connection channel 4 and the first fixed threaded channel 11 and the third threaded connection channel 17;

[0063] When urine sampling is required from a male patient, medical staff can take out a disposable male urine sampler and thread it to the first fixed threaded channel 11 and the first threaded connection channel 4. After fixing, the sealing plug 9 is inserted into the auxiliary tube 16, so that it is sealed to the auxiliary tube 16 through the first sealing gasket. The threaded connector 10 is then threaded to the second threaded connection channel 5. The patient's penis is placed into the circular urine collection head 13 by holding the handle 1, and the circular urine collection head 13 is rotated according to the direction of the penis to adjust the angle of the circular urine collection head 13. After adjustment, the medical staff can press one of the first airbags 7 to allow air to enter the second airbag 15 from the first tube 8 through the auxiliary tube 16, causing it to inflate. When the first airbag 7 is released, the first airbag 7 rebounds and draws in external air through the first one-way valve 22. By repeatedly pressing the first airbag 7, the medical staff can make the second airbag 15 wrap around and fit against the patient's penis. Then, the degree of inflation of the second airbag 15 is adjusted according to the patient's comfort until the patient stops. When the medical staff stops pressing the first airbag 7, they can instruct the patient to urinate. Urine then enters the circular urine collection head 13. The medical staff can then press the other first airbag 7. At this point, the gas inside the second threaded connection channel 5 is released through the first one-way valve 22. When the first airbag 7 rebounds, it draws the gas inside the second threaded connection channel 5 through the threaded connector 10 into the first flexible tube 8, and then through the second one-way valve 33 into the first airbag 7. This creates negative pressure inside the second threaded connection channel 5, which then affects the circular urine collection head. The urine inside the head 13 enters the first fixed threaded channel 11 through the third one-way valve 34 and the fourth hose 31, and finally enters the urine collection cylinder 2. Through the coordinated operation of various structures, the angle-adjustable circular urine collection head 13 can be precisely fitted into the patient's penis. The airbag is inflated to form a tight and flexible wrap-around seal on the outer wall of the penis. It can adapt to different penile shapes and can adjust the inflation degree of the airbag as needed to take into account the patient's comfort. It forms a leak-free, sealed urine collection area, thereby improving the device's adaptability to the male patient's urethra.

[0064] When urine sampling is required from a female patient, medical staff can use a disposable female urine sampler to connect and secure the third threaded connection channel 17 to the first threaded connection channel 4. After securing, the sealing plug 9 is inserted into the second tubing 21, sealing it with the second tubing 21 through the first sealing gasket. The threaded connector 10 is then connected and secured to the second threaded connection channel 5. Medical staff can then adjust the direction of the rectangular urine collection head 14 according to the patient's urethral position and align it with the urethra. At this point, medical staff repeat the above steps, pressing the first airbag 7 to allow gas to enter the third airbag 20 through the second tubing 21 and inflate it. When the third airbag 20 is completely fitted between the groin area and the urethra is centered on the rectangular urine collection head 14, medical staff stop pressing the first airbag. 7. Instruct the patient to urinate. Simultaneously, medical staff repeat the above operation by pressing another first airbag 7, allowing urine to be guided through the inclined surface of the guide plate 19 into the fourth hose 31, and then through the fourth one-way valve 35 into the third threaded connection channel 17, finally entering the urine collection cylinder 2. The adjustable rectangular urine collection head 14 is precisely aligned with the female urethra. After the airbag is inflated, it fits the patient's crotch, firmly positioning the urethra in the center of the rectangular urine collection head 14 to form a sealed urine collection space. This effectively prevents the urine collection head from shifting during sampling. Combined with the inclined guiding effect of the guide plate 19, the urine can be quickly and smoothly guided, perfectly adapting to the special physiological structure of women. This solves the problems of easy leakage and incomplete collection of female urine samples, greatly improving the success rate and cleanliness of female sampling, thereby improving the adaptability of the equipment to the female patient's urethra.

[0065] With the structure set up above, and with the help of the linkage between negative pressure suction and the diversion structure, the urine can be collected smoothly and completely on the basis of the patient's natural urination. The patient does not need to deliberately exert force to urinate or adjust their posture to cooperate, which improves the patient's urination comfort. Moreover, the flexible airbag fit and the design without hard pressure can also ensure the sampling sealing effect while reducing the discomfort caused by the patient's pain sensitivity, thereby reducing the difficulty of the urine sampling process and improving the work efficiency of medical staff.

[0066] A rubber pad is provided at the contact point between the urine collection cylinder 2 and the sealing cap 3;

[0067] After the initial urine of a male or female patient is discharged into the urine collection cylinder 2, the initial urine flows to the bottom of the urine collection cylinder 2. At this time, the medical staff rotates the push rod 23, which moves downward inside the gas delivery chamber 30 through the threaded connection with the threaded seat 28. This causes the piston plate 29 to move downward inside the gas delivery chamber 30. At this time, the gas is pushed by the piston plate 29 from the third hose 24 into the arc-shaped gas chamber 26. The gas pushes the arc-shaped piston rod 27, causing the baffle 25 to rotate inside the urine collection cylinder 2. When the push rod 23 can no longer be rotated, the baffle 25 is completely in contact with the inside of the urine collection cylinder 2 and is sealed by the second sealing gasket. The urine at the bottom of the urine collection cylinder 2 is isolated, while the midstream urine is collected. Through the cooperation of the above structure, after the patient urinates the initial urine, medical staff can simply rotate the push rod 23 to drive the baffle 25 to rotate and close precisely inside the urine collection cylinder 2. Relying on the sealing effect of the second sealing gasket, the initial urine at the bottom of the urine collection cylinder 2 is completely isolated, realizing the accurate collection of midstream urine that meets clinical testing standards. This effectively avoids the problem of urine test result deviation caused by impurities and easy contamination in the initial urine, ensuring the accuracy and effectiveness of urine sample testing, thereby improving the work efficiency of medical staff.

[0068] After collection, medical staff remove the urine sampler, unscrew it, and then unscrew the sealing cap 3. They then put the collected midstream urine into the urine analyzer for testing. After that, the inside of the urine collection cylinder 2 is disinfected and cleaned for future use, thereby improving the overall usability of the equipment.
