Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a urine collector for non-invasive collection of urine samples. Background Technology

[0002] Female patients often require bed rest due to certain illnesses, leading to changes in their urination position. Because the female urethra is anatomically located near the anus, it is difficult for bedridden patients to collect urine samples for testing, and this can easily cause contamination, affecting the quality of the urine sample.

[0003] When urine samples need to be collected for testing, different testing requirements necessitate either full-stream or midstream urine samples, which can be difficult for patients' families to perform. Clinically, catheterization is often used to help bedridden female patients collect urine samples; however, catheterization is an invasive procedure, causing most patients to experience a foreign body sensation, and it also increases the workload of medical staff.

[0004] In conclusion, the existing structure obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

When the valve core is rotated to a second position, the connecting channel connects the inlet channel and the second outlet channel. The inlet channel is connected to the urine outlet tube via a first conduit. A first urine collection cylinder is connected to the first outlet channel via a second conduit, meaning that when the valve core is rotated to the first position, urine flows into the first urine collection cylinder through the first outlet channel. A second urine collection cylinder is connected to the second outlet channel via a third conduit, meaning that when the valve core is rotated to the second position, urine enters the second urine collection cylinder through the second outlet channel. This allows for the collection of either full-stream or mid-stream urine, avoiding invasive procedures, and is easy to operate, suitable for both medical staff and patients' families.

[0029] See Figures 1-2 In one embodiment of this utility model, a non-invasive urine collection device 100 for collecting urine samples is provided, suitable for female bedridden patients, comprising:

[0030] The urinary catheter 10 includes a urine bag body 11, and an adhesive component 12 is provided at one end of the urine bag body 11. The adhesive component 12 includes a base plate 121 and medical adhesive 122. The base plate 121 is connected to the urine bag body 11. The medical adhesive 122 is bonded to the outer surface of the base plate 121. A urine inlet 123 is provided on the adhesive component 12, and the urine inlet 123 communicates with the interior of the urine bag body 11. A urine outlet tube 13 is also provided at the other end of the urine bag body 11, and the urine outlet tube 13 communicates with the interior of the urine bag body 11.

[0031] The three-way valve 20 includes a valve body 21 and a valve core. The valve body 21 includes an inlet channel 211, a first outlet channel 212, and a second outlet channel 213. The valve core is rotatably disposed within the valve body 21 and has a connecting channel. When the valve core is rotated to the first position, the connecting channel connects the inlet channel 211 and the first outlet channel 212. When the valve core is rotated to the second position, the connecting channel connects the inlet channel 211 and the second outlet channel 213. The inlet channel 211 is connected to the urine outlet tube 13 through a first conduit 214.

[0032] The first urine container 30 is connected to the first liquid outlet channel 212 via the second conduit 31;

[0033] The second urine container 40 is connected to the second discharge channel 213 via the third conduit 41.

[0034] In this implementation, the urine collection device 100 can non-invasively collect midstream or fullstream urine samples from bedridden patients in clinical practice, and the urine collection device 100 is suitable for female patients. Specifically, the catheter bag 10 is used to collect the patient's urine so that the urine can be channeled through the three-way valve 20 into the first urine collection cylinder 30 and / or the second urine collection cylinder 40. For example, when it is necessary to collect a midstream urine sample, the patient's initial urine sample is first collected into the first urine collection cylinder 30, and then the three-way valve 20 is turned to connect to the second urine collection cylinder 40 to collect the midstream urine sample into the second urine collection cylinder 40. The catheter bag 10 has a urine bag body 11, an adhesive piece 12, and a urine outlet tube 13. The adhesive piece 12 can be attached to the skin around the patient's vulva to prevent urine leakage. The adhesive component 12 has a urine inlet 123, which covers the patient's urethral opening, allowing urine to enter the urine bag body 11 through the inlet 123, thus achieving urine collection. The adhesive component 12 has a base 121 and medical adhesive 122. The base 121 holds the medical adhesive 122, which is non-toxic, sterile, non-irritating to human tissue, and has good adhesive strength. The medical adhesive 122 is used to adhere to the patient's skin to prevent urine leakage. The urine entering the urine bag body 11 through the urine inlet 123 flows out through the urine outlet tube 13 to the three-way valve 20. The three-way valve 20 has one inlet channel 211 and two outlet channels. Whether the inlet channel 211 is connected to the two outlet channels is controlled by the valve core. The valve core is optionally located at the junction of the inlet channel 211, the first outlet channel 212, and the second outlet channel 213. The valve core has a connecting channel. When the valve core is rotated to the first position, the two ends of the connecting channel are connected to the inlet channel 211 and the first outlet channel 212, respectively. Since the first outlet channel 212 is connected to the first urine collection cylinder 30 through the second conduit 31, urine enters the first urine collection cylinder 30 when the valve core is in the first position. When the valve core is rotated to the second position, the two ends of the connecting channel are connected to the inlet channel 211 and the second outlet channel 213, respectively. Since the second outlet channel 213 is connected to the second urine collection cylinder 40 through the third conduit 41, urine enters the second urine collection cylinder 40 when the valve core is in the second position. This realizes the segmented collection of urine samples to facilitate testing needs.

[0035] As an optional embodiment, the urine bag body 11 is provided with a plurality of guide strips inside, the guide strips extending from the urine inlet 123 to the urine outlet 13, and the guide strips are made of medical silicone rubber material.

[0036] In this embodiment, the guide strip is used to guide urine along the guide strip into the urinary catheter 13, and the guide strip supports the internal space of the urine bag body 11, preventing the two inner surfaces of the urine bag body 11 from sticking together and affecting the flow of urine. The guide strip is made of medical-grade silicone rubber material, which is non-toxic and non-polluting. Since there is a distance between the vulva and the bed for bedridden patients, when the urine collector 100 is used on bedridden patients, the urine bag body 11 can form a downward slope to facilitate the flow of urine into the urinary catheter 13. The arrangement of multiple guide strips can keep the downward slope of the urine bag body 11 stable and guide the urine into the urinary catheter 13.

[0037] As an optional embodiment, see Figures 1-2 The chassis 121 is made of medical-grade soft silicone material;

[0038] The base 121 is circular or elliptical. The base 121 includes an inner ring 1211 and an outer ring 1212 extending outward from the inner ring 1211. The urine inlet 123 is opened in the inner ring 1211. The inner ring 1211 is connected to the urine bag body 11.

[0039] The outer surface of the medical adhesive 122 is covered with medical release paper.

[0040] In this embodiment, the urine bag body 11 is connected to the inner ring 1211 of the base 121, meaning the outer ring 1212 is located outside the urine bag body 11. Therefore, when attaching the adhesive piece 12 to the patient, the outer ring 1212 can be independently pinched for easier attachment. Furthermore, since the base 121 is made of medical-grade soft silicone, it is not only non-toxic and odorless but also conforms better to the patient's skin, and the outer ring 1212 can be easily cut to a suitable size. Medical release paper protects the medical adhesive 122; the release paper is removed when needed.

[0041] As an optional embodiment, see Figures 1-2 The three-way valve 20 also includes a handle 22, which is connected to the valve core and located outside the valve body 21; the handle 22 is provided with a first indicator rod 221, a second indicator rod 222, and a third indicator rod 223 extending in different directions respectively. When the valve core is rotated to the first position, the projection of the first indicator rod 221 on the valve body 21 overlaps with the inlet channel 211, the projection of the second indicator rod 222 on the valve body 21 overlaps with the first outlet channel 212, and the projection of the third indicator rod 223 on the valve body 21 deviates from the second outlet channel 213 (see...). Figure 2 When the valve core rotates to the second position, the projection of the first indicator rod 221 on the valve body 21 overlaps with the inlet channel 211, the projection of the third indicator rod 223 on the valve body 21 overlaps with the second outlet channel 213, and the projection of the second indicator rod 222 on the valve body 21 deviates from the first outlet channel 212 (see...). Figure 1 ).

[0042] In this embodiment, the operator of the urine collector 100 can rotate the valve core by operating the handle 22, thereby adjusting the connection status of each channel. Three indicator rods on the handle 22 indicate the current position of the valve core, that is, the connection status between the inlet channel 211 and the outlet channel. Specifically, the first indicator rod 221, the second indicator rod 222, and the third indicator rod 223 form a T-shape; the angle between the first indicator rod 221 and the second indicator rod 222 and the third indicator rod 223 is 90 degrees; the angle between the second indicator rod 222 and the third indicator rod 223 is 180 degrees (see [reference]). Figures 1-2 The three-way valve 20 can be selected as a medical three-way valve 20.

[0043] As an optional embodiment, see Figures 1-2 The first urine collection container 30 includes a first urine collection container body 32, a first top cover 33, and a first bottom cover 34. The top of the first urine collection container body 32 is provided with a first liquid inlet. The first top cover 33 is detachably connected to the top of the first urine collection container body 32 and covers the first liquid inlet. The first top cover 33 is integrally formed with a second conduit 31, and the second conduit 31 communicates with the first liquid inlet. The first bottom cover 34 is detachably connected to the bottom of the first urine collection container body 32, and the first bottom cover 34 is adapted to the top of the first urine collection container body 32.

[0044] The second urine container 40 includes a second urine container body 42, a second top cover 43, and a second bottom cover 44. The top of the second urine container body 42 is provided with a second liquid inlet. The second top cover 43 is detachably connected to the top of the second urine container body 42 and covers the second liquid inlet. The second top cover 43 is integrally formed with a third conduit 41, and the third conduit 41 communicates with the second liquid inlet. The second bottom cover 44 is detachably connected to the bottom of the second urine container body 42 and is adapted to the top of the second urine container body 42.

[0045] In this embodiment, the first top cover 33 and the second conduit 31 are integrally formed. The second conduit 31 is connected to the first outlet channel 212. When the first outlet channel 212 is connected to the inlet channel 211, urine flows into the first urine collection container body 32 through the first inlet. After the urine collection in the first urine collection container body 32 is completed, the first top cover 33 and the first bottom cover 34 are removed. The first bottom cover 34 is connected to the top of the first urine collection container body 32, covering the first inlet, and then the urine is sent for testing. The second urine collection container 40 is handled similarly. Specifically, the first top cover 33 is threaded to the top of the first urine collection container body 32; the first bottom cover 34 is threaded to the bottom of the first urine collection container body 32; the second top cover 43 is threaded to the top of the second urine collection container body 42; and the second bottom cover 44 is threaded to the bottom of the second urine collection container body 42. The threaded connection not only facilitates disassembly but also avoids excessive force that could cause urine spillage.

[0046] As an optional embodiment, the first urine container body 32 and the second urine container body 42 are made of transparent material, and scale lines 50 are provided on the first urine container body 32 and the second urine container body 42 to facilitate observation of urine and urine volume.

[0047] As an optional embodiment, the urine bag body 11 is made of transparent medical-grade silicone rubber or transparent medical-grade polyethylene material. The transparent material of the urine bag body 11 facilitates observation of the urine inside. The urine bag body 11 made of medical-grade silicone rubber or medical-grade polyethylene material is odorless, non-toxic, and has a certain degree of flexibility, avoiding irritation to the patient during use.

[0048] The procedure for using the non-invasive urine collection device 100 to collect midstream urine samples is as follows:

[0049] Clean the vulva and surrounding skin of the bedridden patient, and shave pubic hair if necessary. The urine bag body 11 of the urinary catheter 10 is flexible. Adjust the direction, position, and / or shape of the urine bag body 11 so that after the adhesive piece 12 is attached to the patient, the urinary catheter 13 is in a horizontal or horizontally downward position to facilitate urine flow. After confirming the position and orientation of the urinary catheter 13, peel off the medical release paper on the adhesive piece 12, cover the urinary inlet 123 of the adhesive piece 12 with the patient's urethral opening, and gently press the base 121 of the adhesive piece 12 so that the medical adhesive 122 adheres to the patient's vulvar skin to prevent urine leakage. The three-way valve 20 is connected to the urinary catheter 13 via the first conduit 214, which is a flexible tube. The three-way valve 20, the first urine collection cylinder 30, and the second urine collection cylinder 40 are positioned relatively low to the urinary catheter 13 using the first conduit 214. The positions of the first and second urine collection cylinders 30 and 40 can also be adjusted via the second and third conduits 31, which are also flexible tubes. When the valve core of the three-way valve 20 is rotated to the first position, the inlet channel 211 of the three-way valve 20 is connected to the first outlet channel 212. The first outlet channel 212 is connected to the first urine collection cylinder 30 via the second conduit 31. When the patient expels the first portion of urine, the first portion enters the urine bag body 11. Because the vulva of a bedridden patient is at a distance from the bed, the urine bag body 11 can form a downward slope, facilitating the flow of urine through the guide strip inside the urine bag body 11 to the urinary catheter 13. Of course, because the urine bag body 11 is flexible, medical staff or family members can use [other methods] to [further instructions]. Smooth or adjust the urine bag body 11 to assist in guiding the urine to the outflow tube 13. After the first urine flows into the first urine collection cylinder 30, turn the valve core of the three-way valve 20 to the second position. At this time, the middle urine discharged by the patient flows into the second urine collection cylinder 40, completing the collection of the middle urine. After collection, remove the second top cover 43 and the second bottom cover 44 of the second urine collection cylinder 40. Dispose of the second top cover 43 and the third catheter 41 into the medical waste bin. Place the second bottom cover 44 on the top of the second urine collection cylinder body 42 and send the middle urine sample from the second urine collection cylinder 40 for testing.

[0050] In summary, this utility model discloses a non-invasive urine collection device suitable for female bedridden patients. It includes a urinary catheter bag, a three-way valve, a first urine collection cylinder, and a second urine collection cylinder. The urinary catheter bag is used to guide the patient's urine into the first and second urine collection cylinders via the three-way valve. For example, when collecting midstream urine, the valve core of the three-way valve is rotated to the first position to guide the initial portion of the patient's urine into the first urine collection cylinder. Then, the valve core of the three-way valve is rotated to the second position to guide the midstream urine into the second urine collection cylinder, thereby achieving the collection of midstream urine. Specifically, the urinary catheter includes a catheter body, an adhesive component, and an outlet tube. An adhesive component is located at one end of the catheter body; this component includes a base and medical adhesive, connecting the base to the catheter body. The medical adhesive is bonded to the outer surface of the base. An inlet is provided on the adhesive component, communicating with the interior of the catheter body. The catheter is stably fixed to the vulva of the female patient via the adhesive component to prevent urine leakage. The inlet on the adhesive component covers the urethral opening of the female patient, allowing urine to enter the catheter body through the inlet. An outlet tube is also provided at the other end of the catheter body, communicating with the interior of the catheter body. The catheter body collects urine and guides it into the outlet tube, which is connected to the inlet channel of a three-way valve. The three-way valve includes a valve body and a valve core. The valve body includes an inlet channel, a first outlet channel, and a second outlet channel. The valve core is rotatably disposed within the valve body and has a connecting channel. When the valve core is rotated to a first position, the connecting channel connects the inlet channel and the first outlet channel. When the valve core is rotated to a second position, the connecting channel connects the inlet channel and the second outlet channel. The inlet channel is connected to the urine outlet tube via a first conduit. A first urine collection cylinder is connected to the first outlet channel via a second conduit, meaning that when the valve core is rotated to the first position, urine flows into the first urine collection cylinder through the first outlet channel. A second urine collection cylinder is connected to the second outlet channel via a third conduit, meaning that when the valve core is rotated to the second position, urine enters the second urine collection cylinder through the second outlet channel. This allows for the collection of either full-stream or mid-stream urine, avoiding invasive procedures, and is easy to operate, suitable for both medical staff and patients' families.

[0051] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
