Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an optimized sampling device for clinical endocrine care. The patent title of this utility model may also be "An Optimized Urine Sampling Device for Clinical Endocrine Care". Background Technology

[0002] Endocrinology is a department specializing in the diagnosis and treatment of endocrine system diseases and related metabolic disorders, and urinalysis plays a crucial role in this process. Urinalysis not only helps diagnose endocrine disorders but also monitors treatment effectiveness and assesses changes in the condition. Therefore, routine urinalysis is a fundamental examination in endocrinology, used for preliminary screening of urinary and endocrine system-related diseases. To ensure the accuracy of urinalysis results, sample collection must avoid contamination with semen and prostatic fluid, and for women, vaginal secretions. Typically, "midstream urine" should be collected, and the urine collection cup should be kept free from contamination. The sample should be sent for testing within 1-2 hours. Current technology usually uses only a small measuring cup for urine collection, which can easily contaminate the hands during collection, and the cup remains open during transport, making spillage or contamination more likely.

[0003] Chinese Patent Application Document 1 (Application No.: 2020208818758, Application Date: 2020.05.24) discloses a urine sampling device for clinical endocrine care, including a sampling cup 1', a hinge on the side of the sampling cup 1', a cup lid 3' movably connected to the sampling cup 1' via the hinge, a sealing ring on the side of the cup lid 3', a through hole at the top of the cup lid 3', a rubber membrane placed inside the through hole, a funnel 4' above the cup lid 3', and an insertion tube connected to the bottom of the funnel 4'. The tube is inserted into the rubber membrane, and a flexible tube 9' is provided on the top of the cup lid 3'. A sealing plug is provided inside one end of the flexible tube 9'. The opening of the funnel 4' in the above scheme is too small, which can easily contaminate the hands during the sampling process. At the same time, the tube of the funnel 4' is narrow and has no anti-overflow structure, which can easily cause it to overflow and make hands dirty after overflowing. In addition, the funnel 4' lacks shock absorption when fixed, and it can easily splash out during the high-speed jet of midstream urine sampling. Furthermore, the lifting ring located directly below the funnel 4' does not provide any anti-hand dirt function when the funnel 4' overflows, which is a redundant design.

[0004] Chinese Patent Application Document 2 (Application No.: 202321388962X, Application Date: 2023.06.02) discloses a collection and storage device, including an external threaded ring, a bottle cap, a fixing ring, a funnel, a funnel cap, a fixing sleeve, a screw, a handle, a first sealing plug, a liquid delivery channel, a drain pipe, a baffle, and a second sealing plug. When the funnel cap is opened, urine can enter the storage bottle from the liquid delivery channel of the funnel and the fixing ring. After collection, the funnel cap is closed, and the screw on the fixing sleeve is rotated using the handle, causing the first sealing plug to descend into the liquid delivery channel. However, the funnel opening area of ​​the above solution is not wide enough, making it easy to get hands dirty during collection. Furthermore, the complex structure of the threaded ring, bottle cap, fixing ring, funnel, funnel cap, fixing sleeve, screw, handle, first sealing plug, liquid delivery channel, drain pipe, baffle, and second sealing plug makes the device heavy and complex. It has a high cost for single-use applications, and lacks sufficient hygienic dead zones for repeated use, thus lacking practicality.

[0005] Chinese Patent Application Document 3 (Application No.: 2023221583404, Application Date: 2023.08.11) discloses a urine specimen collector, including a collection cup and a base. A cup lid 2 is installed on the collection cup, and a channel tube is provided on the cup lid 2. An interface part is fixed on the channel tube. The interface part is funnel-shaped 3 and communicates with the collection cup through the channel tube. The opening of the interface part is tilted upward. The collection cup and the base are relatively fixed. The interface part of the above solution is bulky. After collecting urine, the interface part is easily touched during the delivery process, causing the collection cup to tip over. Moreover, the interface part makes the collection cup larger overall, which is not conducive to the simultaneous transfer of urine between different departments in the hospital, and has low practicality.

[0017] Therefore, providing a sampling device for endocrine clinical care that not only provides rapid diversion and has an anti-overflow structure, but also has a wide opening that is not easy to splash or soil hands, while being simple in design, economical to manufacture, and easy to use and transport, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0018] In view of this, the present invention provides an optimized sampling device for clinical endocrine care, which solves the problems of slow drainage, lack of anti-overflow structure, narrow opening that is easy to splash or soil hands, uneconomical manufacturing, and inconvenient use and transportation.

[0019] This application provides an optimized sampling device for clinical endocrine care, including a sampling cup, a disc-shaped cup lid, and a funnel movably connected to the cup lid;

[0020] The sampling cup includes a frustum-shaped cup body and a triangular wing-shaped spout. The cup body includes an upper bottom surface, a lower bottom surface, and a side surface. The upper bottom surface is parallel to the lower bottom surface. The upper bottom surface, the side surface, and the lower bottom surface together form a frustum-shaped cup body. The diameter of the upper bottom surface is larger than the diameter of the lower bottom surface. The upper bottom surface has an opening that matches the cup lid. The opening extends through the upper bottom surface in the direction from the lower bottom surface to the upper bottom surface. The edge of the upper bottom surface has a notch that is recessed to the lower bottom surface. The triangular wing-shaped spout is integrally connected to the side surface of the cup body with the corresponding notch. The angle between the side of the spout away from the side surface and the side surface of the corresponding cup body is less than 45 degrees.

[0021] The cup lid includes a circular plate-shaped lid body and a sealing element. The circumferential edge of the lid body at the opening is fixedly connected to the inner edge of the upper bottom surface. The lid body has a circular perforation and a circular sealing through-hole. The circular perforation and the sealing through-hole penetrate the lid body in the direction from the lower bottom surface to the upper bottom surface. The circular perforation is located at the center of the lid body, and the sealing through-hole is close to the circular perforation and points in the direction from the lower bottom surface to the upper bottom surface. The orthographic projection of the sealing through-hole does not overlap with the orthographic projection of the circular perforation. The outer diameter of the lid body is larger than the radius of the upper bottom surface of the cup body, and the radius of the circular perforation is not greater than 1 / 3 of the radius of the upper bottom surface of the cup body. The sealing element is installed in the sealing through-hole.

[0022] The sealing element includes a circular sealing plate and a rotating column. The sealing plate is in parallel contact with the bottom surface of the cover body near the cup body, and the area of ​​the sealing plate is larger than the area of ​​the sealing through hole. One end of the rotating column is attached to the sealing plate at a position along its circumferential edge near the cover body. The other end of the rotating column extends perpendicularly through the sealing through hole to the bottom surface of the cover body away from the cup body. The length direction of the rotating column is from the top surface to the bottom surface. The diameter of the rotating column is not less than the diameter of the sealing through hole. When the rotating column is rotated on the bottom surface of the cover body away from the cup body, the sealing plate rotates in the plane of the cover body with the rotating column as the axis of rotation. The rotation trajectory of the sealing plate is a circle with the rotating column as the center. The circular perforation is within the circular range of the rotation trajectory.

[0023] Along the direction from the upper bottom surface to the lower bottom surface, the funnel includes an elliptical frustum-shaped opening, a cylindrical corrugated tube, and a cylindrical fixed part connected in sequence; the side of the opening near the corrugated tube and the side of the corrugated tube near the opening are integrally connected.

[0024] The opening of the vent faces away from the lid and points perpendicular to the upper bottom surface towards the lower bottom surface. The side view of the vent is an inverted trapezoid. The upper top surface of the vent is larger than its lower top surface. The diameter of the upper top surface of the vent is at least three times its height. The lower top surface of the vent coincides with one end of the bellows. The other end of the bellows is fixedly connected to the end of the fixing part near the bellows. The length extension direction of both the bellows and the fixing part is along the upper bottom surface towards the lower bottom surface. The end of the fixing part away from the bellows is movably and fixedly snapped into a circular perforation. The upper top surface of the vent is also provided with a funnel-shaped spout facing the same direction as the cup spout.

[0025] The upper surface of the opening is elliptical, and its lower surface is circular; the major axis of the upper surface of the opening is at least 1.2 times greater than its minor axis, and the length of the minor axis of the upper surface of the opening is greater than the outer diameter of the cover; one focal point of the upper surface of the opening coincides with the central axis of the lower surface of the opening.

[0026] Compared with the prior art, the optimized sampling device for clinical endocrine care provided by this utility model achieves at least the following beneficial effects:

[0027] First, the optimized endocrine clinical nursing sampling device provided by this utility model not only solves the problems of slow drainage and overflow due to untimely drainage; firstly, the cover of this utility model has a circular perforation no larger than its outer diameter, which allows for rapid drainage of urine during the cover stage; and secondly, the diameter of the corrugated tube and the fixing part is equal to the diameter of the circular perforation, which allows for rapid drainage of urine during the funnel stage; at the same time, a funnel nozzle is provided on the open part, which can balance the internal and external air pressure of the cup and facilitate rapid drainage of urine; in addition, during urine collection, the cup is tilted, and the corrugated tube makes the funnel nozzle face the lower side, so when the open part is too full of urine, it can be tilted out from the funnel nozzle to prevent the funnel from overflowing.

[0028] Secondly, this invention provides an optimized sampling device for clinical endocrine care, which solves the problems of inefficient collection and messy hands during the collection process. Firstly, the diameter of the top surface of the opening is at least a multiple of its height, and the opening has a large elliptical collection surface, allowing for rapid urine collection. Furthermore, the far focal point of the elliptical opening allows for urine collection, while the cup body on the near focal point side of the elliptical opening can be held, avoiding splashing and messy hands due to excessive proximity to urine. Simultaneously, the corrugated tube provides shock absorption for the opening, giving it flexibility to extend and bend during collection, preventing splashing caused by rigid impact between urine and the opening. Furthermore, the inclination of the corrugated tube allows for an even larger collection surface after bending, further enhancing collection efficiency. In addition, this invention features a spout on the cup body, and the inclination of the cup body causes the spout to face the lower side. After collection, excess urine in the cup can be poured out from the spout, preventing overflow and messy hands.

[0029] Third, the optimized endocrine clinical nursing sampling device provided by this invention solves the problems of complex manufacturing and use, and safe transportation. This invention is easy to operate; it only requires a one-step snap-fit ​​of the funnel's fixing part, and the fixing part can be pulled open after use for quick disassembly of the funnel. Lowering the overall center of gravity of the cup enhances its stability during placement and transportation. Furthermore, the fixing part also functions as a quick-locking mechanism and a high-flow-rate container, achieving multiple functions. In addition, after disassembling the funnel, the circular perforation of the cup lid can be quickly sealed using a sealing plate and a rotating column, preventing liquid from spilling from the spout, avoiding waste, and further improving the safety and stability of transportation.

[0030] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

The optimized sampling device for clinical endocrine care can also be an optimized urine sampling device for clinical endocrine care. The optimized sampling device for clinical endocrine care includes a sampling cup 1, a disc-shaped cup lid 2, and a funnel 3 movably connected to the cup lid 2.

[0047] The sampling cup 1 includes a frustum-shaped cup body 11 and a triangular wing-shaped spout 12. The cup body 11 includes an upper bottom surface, a lower bottom surface, and a side surface. The upper bottom surface is parallel to the lower bottom surface. The upper bottom surface, the side surface, and the lower bottom surface together form a frustum-shaped groove. The diameter of the upper bottom surface is larger than the diameter of the lower bottom surface. The upper bottom surface has an opening that matches the cup lid 2. The opening extends through the upper bottom surface in the direction from the lower bottom surface to the upper bottom surface. The edge of the upper bottom surface has a notch that is recessed to the lower bottom surface. The triangular wing-shaped spout 12 is integrally connected to the side surface of the cup body 11 with the corresponding notch. The angle between the side of the spout 12 away from the side surface and the side surface of the corresponding cup body 11 is less than 45 degrees.

[0048] The cup lid 2 includes a circular plate-shaped lid body 21 and a sealing element 22. The circumferential edge of the lid body 21 at the opening is fixedly connected to the inner edge of the upper bottom surface. The lid body 21 has a circular perforation 211 and a circular sealing through hole 223. The circular perforation 211 and the sealing through hole 223 penetrate the lid body 21 in the direction from the lower bottom surface to the upper bottom surface. The circular perforation 211 is located at the center of the lid body 21. The sealing through hole 223 is close to the circular perforation 211 and is located in the direction from the lower bottom surface to the upper bottom surface. The orthographic projection of the sealing through hole 223 does not overlap with the orthographic projection of the circular perforation 211. The outer diameter of the lid body 21 is larger than the radius of the upper bottom surface of the cup body 11, and the radius of the circular perforation 211 is not greater than 1 / 3 of the radius of the upper bottom surface of the cup body 11. The sealing element 22 is installed in the sealing through hole 223.

[0049] The sealing element 22 includes a circular sealing plate 222 and a rotating column 221. The sealing plate 222 is in parallel contact with the cover 21 on the side of the cover 21 near the bottom surface of the cup 11, and the area of ​​the sealing plate 222 is larger than the area of ​​the sealing through hole 223. One end of the rotating column 221 is attached to the sealing plate 222 at a position along its circumferential edge on the side of the cover 222 near the cover 21. The other end of the rotating column 221 extends vertically through the sealing through hole 223 to the side of the cover 21 away from the bottom surface of the cup 11. The length direction of the rotating column 221 is Z, pointing from the top surface to the bottom surface. The diameter of the rotating column 221 is not less than the diameter of the sealing through hole 223. When the rotating column 221 is rotated on the side of the cover 21 away from the bottom surface of the cup 11, the sealing plate 222 rotates in the plane of the cover 21 with the rotating column 221 as the axis of rotation. The rotation trajectory of the sealing plate 222 is a circle with the rotating column 221 as the center. The circular perforation 211 is within the circular range of the rotation trajectory.

[0050] Along the direction Z from the upper bottom surface to the lower bottom surface, the funnel 3 includes an elliptical frustum-shaped opening 31, a cylindrical corrugated pipe 32, and a cylindrical fixed part 33 connected in sequence; the side of the opening 31 near the corrugated pipe 32 and the side of the corrugated pipe 32 near the opening 31 are integrally connected.

[0051] The opening of the opening 31 is opposite to the side of the cover 21, and is perpendicular to the upper bottom surface and points to the lower bottom surface. The side view projection shape of the opening 31 is an inverted trapezoid. The upper top surface of the opening 31 is larger than its lower top surface. The diameter of the upper top surface of the opening 31 is at least three times its height. The lower top surface of the opening 31 coincides with and is connected to one end of the bellows 32. The other end of the bellows 32 is fixedly connected to the end of the fixing part 33 near the bellows 32. The length extension direction of both the bellows 32 and the fixing part 33 is Z, which is along the upper bottom surface and points to the lower bottom surface. The end of the fixing part 33 away from the bellows 32 is movably and fixedly snapped to the circular cutout 211. The upper top surface of the opening 31 is also provided with a funnel spout facing the same direction as the spout 12. The funnel spout is triangular wing shaped.

[0052] The upper top surface of the opening 31 is elliptical, and its lower top surface is circular; the major axis of the upper top surface of the opening 31 is at least 1.2 times greater than its minor axis, and the length of the minor axis of the upper top surface of the opening 31 is greater than the outer diameter of the cover 21; one focal point of the upper top surface of the opening 31 coincides with the central axis of the lower top surface of the opening 31.

[0053] Specifically, continue to refer to Figure 2 and Figure 3As shown, the sampling cup 1 includes a cup body 11, which can be made of polyurethane. Polyurethane cup bodies are inexpensive, readily available, and easy to manufacture and obtain. Furthermore, they are lightweight, making them easy to handle and transport. The cup body 11 is a frustum-shaped groove with an opening on its upper bottom surface. The opening faces the lid 2 and the funnel 3, and this opening can be considered the cup rim. The area of ​​the upper bottom surface of the cup body 11 is larger than the area of ​​its lower bottom surface, and the upper and lower bottom surfaces are parallel to each other. A routine urinalysis typically requires approximately 5-10 ml of urine, and the cup body 11 has a volume of 13-15 ml, used to hold the urine. The cup body 11 has a frosted surface on its circumferential side, specifically on the outer side of the cup body 11 away from the inner wall of its groove. The outer side of the cup body 11 is made to have a rough texture by sandblasting, grinding and other methods, similar to the sandpaper effect. By increasing the roughness of the side of the cup body 11, the stability of the cup body 11 can be increased.

[0054] The cup body 11 has a notch at the edge of its rim. This notch extends along the tip of the spout 12, pointing X through the side of the cup body 11. The notch is an isosceles triangle, with its base coinciding with the rim of the cup body 11. The spout 12 is integrally connected to the side of the notch away from the central axis of the cup body 11. The spout 12 is triangular in shape, with its tip pointing away from the central axis of the cup body 11. The spout 12 is fixedly connected to the outer wall of the opening side of the cup body 11. One side of the spout 12 is parallel to the rim of the cup body 11, pointing Z from the upper bottom surface to the lower bottom surface. The height of the spout 12 is lower than the height of the rim of the cup body 11. The angle between the side of the spout 12 away from the cup body 11 and the side of the cup body 11 is less than 45 degrees. The spout 12 is used to guide the urine in the cup body 11. The smaller angle allows the urine to be guided to a more distant location.

[0055] Continue to refer to Figures 2-5As shown, the lid 2 is parallel to the upper bottom surface of the cup body 11 and is glued to the cup body 11. Along the direction Z from the upper bottom surface to the lower bottom surface, the top view projection of the cup body 11 coincides with the top view projection of the lid 2. The cup body 11 includes a lid 21 with a hollow circular plate and a sealing element 22 that penetrates the lid 21. The lid 21 and the sealing element 22 are made of the same material as the cup body 11. The lid 21 is a circular plate with a circular perforation 211 in the center. The outer diameter of the lid 21 is at least 10 mm larger than the radius of the upper bottom surface of the cup body 11. The slightly larger lid 21 facilitates the formation of an outwardly protruding cup rim at the cup opening, making it easier to pick up the cup body 11 along the circumference of the cup opening. The central axis of the circular perforation 211 coincides with the central axis of the cover 21, and the radius of the circular perforation 211 is greater than 1 / 3 of the outer diameter of the cover 21. A fixing part 33 of the funnel 3 is fixedly installed inside the circular perforation 211. After the cover 21 and the cup 11 are glued and fixed, the circular perforation 211 is used to allow the interior of the cup 11 to communicate with the exterior. Along the direction Z from the upper bottom surface to the lower bottom surface, the cover 21 is provided with a through sealing hole 223. The sealing hole 223 is circular in shape and is specifically located at any edge along the circumference of the circular perforation 211. The vertical distance between the sealing hole 223 and the circular perforation 211 is not greater than 15mm. The sealing hole 223 is used to fix the sealing element 22.

[0056] The sealing element 22 includes a plate-shaped sealing sheet 222 and a rotating post 221. The sealing sheet 222 is a circular plate made of the same material as the cover 21, with a radius larger than the radius of the circular perforation 211, and an area larger than the area of ​​the circular perforation 211. The sealing sheet 222 is disposed on the side of the cover 21 near the cup body 11, parallel to the cover 21, and in contact with the cover 21 on the side near the cover 21. One end of the rotating post 221 is fixedly bonded to the sealing sheet 222 at any position along its circumferential edge on the side near the cover 21. Through the rotating post 221, the sealing sheet 222 can rotate. The rotating shaft rotates in a horizontal plane; the rotation trajectory of the sealing plate 222 is a circle with the rotating column 221 as the center, and the circular hole 211 is within the circular range of the rotation trajectory; that is, when the sealing plate 222 rotates with the rotating column 221 as the center, in a certain state of rotation of the sealing plate 222, along the direction Z from the upper bottom surface to the lower bottom surface, the top view projection of the circular hole 211 coincides with the top view projection of the sealing plate 222. In another state of rotation of the sealing plate 222, the top view projection of the circular hole 211 and the top view projection of the sealing plate 222 do not overlap at all.

[0057] One end of the rotating column 221 is fixedly connected to the sealing sheet 222 by adhesive bonding. The other end of the rotating column 221 extends vertically through the sealing through-hole 223 to the side of the cover 21 away from the cup body 11. The rotating column 221 is a cylinder extending in the Z direction from the upper bottom surface to the lower bottom surface. In actual use, the end of the rotating column 221 away from the sealing sheet 222 can be rotated on the side of the cover 21 away from the cup body 11, so that the rotating column 221 can drive the sealing sheet 222 to rotate, thereby achieving the sealing sheet 222 overlapping and sealing or opening the circular perforation 211.

[0058] Continue to refer to Figures 2-7 As shown, along the direction Z from the upper bottom surface to the lower bottom surface, the funnel 3 includes an open portion 31, a corrugated tube 32, and a fixing portion 33 connected in sequence; the material of the open portion 31 and the corrugated tube 32 can be the same as the material of the cup body 11. The open portion 31 and the corrugated tube 32 made of polyurethane have the advantages of being inexpensive, readily available, easy to manufacture, and lightweight; the open portion 31 and the corrugated tube 32 are made as a single piece.

[0059] The opening 31 is a hollow frustum open at both ends, pointing X along the tip of the spout 12. The side view of the opening 31 is an inverted trapezoid. The upper surface of the opening 31 is larger than its lower surface, and the upper and lower surfaces are interconnected. The diameter of the upper surface of the opening 31 is at least three times its height, and the wall thickness of the opening 31 is no more than 3 mm. The upper surface of the opening 31 is elliptical, and the length of its major axis is greater than the length of its minor axis. The lower top surface of the opening 31 is circular; the major axis of the upper top surface of the opening 31 is at least 1.2 times greater than its minor axis, and the length of the minor axis of the upper top surface of the opening 31 is greater than the outer diameter of the cover 21; one focal point of the upper top surface of the opening 31 coincides with the central axis of the lower top surface of the opening 31; along the direction Z from the upper bottom surface to the lower bottom surface, the top view projection of one focal point of the upper top surface of the opening 31 coincides with the top view projection of the center of the circle of the lower top surface of the opening 31, and the direction from this focal point of the opening 31 to the other focal point is the direction of the tip of the spout 12 towards X. The opening of the lower top surface of the opening 31 is circular, and the diameter of the opening of the lower top surface of the opening 31 is the same as the diameter of the bellows 32, and it coincides with one end of the bellows 32 for a sealed connection. The upper top surface of the opening 31 is also provided with a funnel-shaped spout that faces the same direction as the spout 12. The funnel nozzle points in the same direction as the spout 12. The funnel nozzle is fixedly installed along one outer wall of the upper surface of the opening 31, with an angle of less than 45 degrees between the funnel nozzle and the outer surface of the opening 31. The funnel nozzle guides the urine within the cup 11, preventing overflow. The smaller angle of the funnel nozzle allows the urine to flow to a more distant location. The upper surface of the opening 31 increases its collection area, facilitating the collection of urine and preventing soiled hands. It also increases collection efficiency, allowing for rapid urine collection and reducing the collection time for midstream urine. Rapid collection also prevents insufficient urine volume during excretion, thus reducing the need to collect the final portion of urine and improving detection accuracy. The lower surface of the opening 31 is used to discharge the collected urine.

[0060] The bellows 32 is a cylindrical tube with a corrugated structure, having at least three thin-walled pleats with transverse corrugations. The bellows 32 is made of the same material as the opening 31, and one end of the bellows 32 is integrally formed with the lower top surface of the opening 31. The polyurethane bellows 32 has the advantages of being inexpensive, readily available, lightweight, and easy to integrate with the opening 31. The other end of the bellows 32 along its length is fixedly connected to one end of the fixing part 33 by adhesive bonding. The length extension direction of both the bellows 32 and the fixing part 33 is Z-direction, pointing from the upper bottom surface to the lower bottom surface. The bellows 32 extends through the middle along its length, and is used to guide the urine collected in the opening 31 into the fixing part 33. The bellows 32 has flexibility to stretch and bend in any direction perpendicular to its length. When the opening 31 collects urine, the bellows 32 can provide a certain buffer when the jet of urine hits the opening 31.

[0061] The fixing part 33 is a hollow cylindrical tube. One end of the fixing part 33 is fixedly glued to the corrugated tube 32, and the other end of the fixing part 33 passes through the circular perforation 211 and is movably fixed on the cover body 21. The diameter of the fixing part 33 is larger than the diameter of the circular perforation 211. The fixing part 33 is made of rubber and can be elastically locked in the circular perforation 211 of the cover body 21. Through the fixing part 33, the opening part 31 and the corrugated tube 32 can be fixed on the cover body 21, so that the urine collected in the opening part 31 can flow into the sealed space formed by the cover body 21 and the cup body 11 through the corrugated tube 32 and the fixing part 33 in sequence.

[0062] In specific use, the optimized endocrine clinical nursing sampling device provided in this embodiment can be used for urine collection in routine urine tests, and its specific operation is as follows;

[0063] First, rotate the end of the rotating column 221 away from the sealing plate 222, causing the sealing plate 222 to rotate about the rotating column 221 as the axis, and check whether the sealing plate 222 can seal or open the circular perforation 211. Then rotate the end of the rotating column 221 away from the sealing plate 222, so that the circular perforation 211 is open and open.

[0064] Then, the fixing part 33 is fastened onto the circular perforation 211 of the lid 21 towards the cup body 11, so that the middle part of the fixing part 33 is elastically engaged with the circular perforation 211 of the lid 21, thus completing the connection between the funnel 3 and the cup lid 2. The cup lid 2 and the cup body 11 are integrally made without additional connection; along the direction Z from the upper bottom surface to the lower bottom surface, the optimized endocrine clinical nursing sampling device provided in this embodiment consists of an open part 31, a corrugated tube 32, a fixing part 33, a cup lid 2, and a cup body 11.

[0065] Furthermore, the user can hold the outer wall of the cup 11 to collect urine. This step is a common technique in the prior art, and this embodiment will not pursue it in detail.

[0066] Finally, after collecting urine, hold the cup body 11 with one hand and pinch the outer wall of the opening 31 with the other hand, then pull off the opening 31 together with the corrugated tube 32 and the fixing part 33. After discarding the funnel 3, rotate the end of the rotating column 221 away from the sealing plate 222 again, so that the sealing plate 222 coincides with the circular perforation 211, and close the sealing circular perforation 211.

[0067] The sealed cup 11 and the collected urine are then sent to the collection window for testing.

[0068] Compared with the prior art, the optimized endocrine clinical nursing sampling device provided in this embodiment achieves at least the following beneficial effects:

[0069] First, the optimized endocrine clinical nursing sampling device provided in this embodiment not only solves the problems of slow drainage and overflow due to untimely drainage; firstly, the cover 21 provided in this embodiment has a circular perforation 211 no larger than 1 / 3 of its outer diameter, which can quickly drain urine in the cover 21 stage; and the diameters of the corrugated tube 32 and the fixing part 33 are equal to the diameter of the circular perforation 211, which can quickly drain urine in the funnel 3 stage; at the same time, the opening 31 is provided with a funnel nozzle, which can balance the internal and external air pressure of the cup 11 and facilitate the rapid drainage of urine; in addition, during urine collection, the cup 11 is tilted, and the corrugated tube 32 makes the funnel nozzle face the lower side. When the opening 31 is too full of urine, it can be tilted out from the funnel nozzle to prevent the funnel 3 from overflowing.

[0070] Secondly, this embodiment provides an optimized sampling device for clinical endocrine care, which solves the problems of inefficient collection and messy hands during the collection process. Firstly, the diameter of the upper surface of the opening 31 is at least three times its height, and the opening 31 has a large elliptical collection surface, allowing for rapid urine collection. Furthermore, the far focal point of the elliptical opening 31 allows for urine collection, while the cup 11 on the near focal point side of the elliptical opening 31 can be held by hand, avoiding splashing and messy hands caused by excessive proximity to urine. Simultaneously, the corrugated tube 32... The opening 31 has a shock-absorbing effect, giving it a certain degree of flexibility in stretching and bending during collection, preventing urine from splashing out due to rigid impact with the opening 31. Furthermore, the inclination of the corrugated tube 3 allows the opening 31 to have a larger collection surface after bending, further enhancing collection efficiency. In addition, this embodiment has a spout 12 on the cup body 11. The inclination of the cup body 11 causes the spout 12 to face the lower side. When collection is complete, excess urine in the cup body 11 can be tilted out from the spout 12, preventing the cup body 11 from overflowing and causing dirty hands.

[0071] Third, the optimized endocrine clinical nursing sampling device provided in this embodiment solves the problems of complex manufacturing and use, and safe transportation. This embodiment is easy to operate; it only requires a one-step snap-fit ​​of the fixing part 33 of the funnel 3, and the fixing part 33 can be pulled open in one step after use for quick disassembly of the funnel 3. Lowering the overall center of gravity of the cup body 11 enhances its placement and transportation stability. Furthermore, the fixing part 33 also functions as a quick-locking mechanism and a high-flow-rate container, achieving multiple functions. In addition, after disassembling the funnel 3, the circular perforation 211 of the cup lid 2 can be quickly sealed using the sealing plate 222 and the rotating column 221, preventing liquid from spilling from the spout 12, avoiding waste, and further improving the safety and stability of transportation.

[0072] In one alternative embodiment, continue to refer to Figures 2-4 As shown, the rotating column 221 has a dumbbell-shaped structure, which includes a middle cylinder and an upper cylinder and a lower cylinder connected to both ends of the middle cylinder. The upper cylinder and the lower cylinder have the same length and radius, and both are greater than the length and radius of the middle cylinder. The middle cylinder is a rubber column with a diameter greater than the diameter of the sealing through hole 223.

[0073] Specifically, the rotating column 221 is a dumbbell-shaped composite cylinder composed of three cylindrical sections. The rotating column 221 includes a coaxially arranged middle cylinder, upper cylinder, and lower cylinder. The upper and lower cylinders are the same size, and their radii are not less than the radius of the middle cylinder, and their lengths are not less than the length of the middle cylinder. The middle cylinder penetrates the sealing through-hole 223 of the cover 21. The length of the middle cylinder is equal to the depth of the sealing through-hole 223, and its radius is greater than the radius of the sealing through-hole 223. The middle cylinder is made of elastic rubber and elastically engages inside the sealing through-hole 223, sealing the through-hole 223 and allowing the middle cylinder to rotate within it.

[0074] The upper cylinder and the lower cylinder are respectively connected to the two ends of the middle cylinder along its length. The upper cylinder is located on the side of the cover 21 near the cup 11, the radius of the lower cylinder is larger than the radius of the middle cylinder, the end of the lower cylinder near the middle cylinder is in contact with the side of the cover 21 near the cup 11, and the end of the lower cylinder away from the middle cylinder is perpendicularly glued to the sealing sheet 222.

[0075] The upper cylinder is located on the side of the cover 21 away from the cup 11. The radius of the upper cylinder is larger than the radius of the middle cylinder and the same as the radius of the middle cylinder. The end of the upper cylinder near the middle cylinder is in contact with the side of the cover 21 that is near and far from the middle cylinder. The middle cylinder, the lower cylinder and the sealing plate 222 can be rotated by pinching the end of the upper cylinder away from the middle cylinder, thereby achieving the sealing plate 222 overlapping and sealing or opening the circular perforation 211.

[0076] Through the above solution, firstly, the rubber cylindrical body can elastically seal the sealing through hole 223 to prevent urine from leaking out of the sealing through hole 223; and it is convenient to rotate the sealing plate 222 from the side of the cover 21 away from the cup body 11 to quickly achieve the overlap and sealing or opening of the circular perforation 211 of the sealing plate 222; at the same time, the dumbbell-shaped rotating column 221 is convenient to engage in the sealing through hole 223, and the structure is simple, lightweight and economical to manufacture.

[0077] In one alternative embodiment, continue to refer to Figure 2 , Figure 6 and Figure 7 As shown, Figure 7 yes Figure 6 Enlarged view at point B; An annular fixing groove 331 extending along the circumference of the fixing part 33 is provided in the middle of the fixing part 33 along the length direction of the fixing part 33, and the annular fixing groove 331 is recessed towards the center of the fixing part 33.

[0078] The cross-sectional shape of the annular fixing groove 331 perpendicular to its length extension direction is U-shaped, and the two side walls of the annular fixing groove 331 along its length extension direction are in contact with the two sides of the cover 21 respectively.

[0079] Specifically, the annular fixing groove 331 is located at the middle of the fixing part 33 along its length extension direction. The length extension direction of the annular fixing groove 331 is the circumferential direction of the fixing part 33, pointing Z from the upper bottom surface to the lower bottom surface. The top view projection of the annular fixing groove 331 is a hollow annular shape. The cross-section of the annular fixing groove 331 perpendicular to its length extension direction is U-shaped. The U-shaped groove opening of the annular fixing groove 331 points away from the central axis of the fixing part 33. The groove depth of the annular fixing groove 331 is less than the thickness of the fixing part 33 and less than the closest distance from the lower cylinder to the circular perforation 211. Through the annular fixing groove 331, the fixing part 33 can be engaged with the circular perforation 211 of the cover 21. When the fixing part 33 is elastically engaged with the cover 21, the two side walls of the annular fixing groove 331 along its length extension direction contact the sides of the cover 21 that are away from or close to the cup body 11, respectively.

[0080] Through the above solution, the fixing part 33 can be further engaged with the circular perforation 211 of the cover 21, enhancing the engagement stability between the fixing part 33 and the cover 21; and further achieving a stable connection between the opening part 31 and the corrugated tube 32, preventing the funnel 3 from falling off or sliding during the urine collection process, thus preventing urine from spilling.

[0081] In one alternative embodiment, continue to refer to Figure 2 As shown, the optimized endocrine clinical nursing sampling device provided in this embodiment also includes a sleeve rod 6 that is sleeved on the outer wall of the cup body 11 along the circumferential direction of the cup body 11. The sleeve rod 6 includes a hollow ring body 61 and a handle 62 that is connected to the ring body 61 at an obtuse angle. The side of the cup body 11 is sleeved inside the ring body 61.

[0082] Specifically, the sleeve 6 is made of metal, which has high rigidity. The sleeve 6 includes a ring 61 and a handle 62 fixedly connected to the outside of the ring 61 by welding. The plane of the ring 61 is parallel to the upper or lower bottom surface of the cup 11. The cross-section of the ring 61 along its length is circular. The inner diameter of the ring 61 is smaller than the diameter of the upper bottom surface of the cup 11 and larger than the diameter of the lower bottom surface of the cup 11. The outer diameter of the ring 61 is smaller than the diameter of the upper bottom surface of the cup 11. The cup 11 can be fitted inside the ring 61, and the side of the cup 11 is in contact with the inner diameter of the ring 61.

[0083] A handle 62 is welded to the outer side of the annular body 61 away from the cup body 11. The cross-section of the handle 62 along its length extension direction is circular, and the diameter of the cross-section of the handle 62 is equal to the diameter of the cross-section of the annular body 61. The length of the handle 62 is not less than 10cm. One end of the handle 62 is welded to the outer side of the annular body 61, and the circular surface of the annular body 61 and the handle 62 form an obtuse angle.

[0084] With the above solution, the cup body 11 can be fitted into the ring body 61, and the cup body 11 can be picked up from a distance via the handle 62; the ring body 61 and the handle 62 can solve the need for people with difficulty bending their arms to pick up urine from a distance, making it convenient for them to collect urine and preventing urine from splashing out and soiling their hands during the collection process.

[0085] In one alternative embodiment, continue to refer to Figure 2 As shown, the side of the cup body 11 is provided with a scale line 4 along its circumference, pointing from the bottom surface to the top surface. The zero scale line of the scale line 4 is at the same horizontal height as the bottom surface of the cup body 11.

[0086] Specifically, the outer wall of the cup body 11 is provided with a scale line 4 extending in a Z direction from the upper bottom surface to the lower bottom surface; the color of the scale line 4 can be black. Existing sampling devices do not have scales, or the scales are raised, adhesive-coated protrusions with unclear markings. The scale line 4 provided in this embodiment is black printed paint. The zero mark of the scale line 4 is at the same horizontal level as the lower bottom surface of the cup body 11, and the length of the scale line 4 extends in the same direction as the width of the side surface of the cup body 11. The scale line 4 is used to indicate the internal volume of the cup body 11.

[0087] The above solution overcomes the problem that the sampling device in the prior art does not have a scale, so that the urine can be weighed relatively accurately during the process of the cup 11 receiving urine, thereby reducing the amount of waste liquid to be treated after testing and saving treatment costs.

[0088] Example 2

[0089] This embodiment is an extension of Embodiment 1. Continue to refer to... Figure 2 and Figure 3 As shown, a label 13 extending along the circumference of the cup body 11 is provided on the side of the outer wall of the cup body 11 away from the scale line 4. The label 13 is a rectangular piece of paper.

[0090] Specifically, existing sampling devices typically require medical staff to affix additional labels to prevent confusion in recording information while queuing at the sample submission window. In this embodiment, a label 13 extending circumferentially is provided on the side of the cup body 11. The label 13 is made of paper, is rectangular, and its length is no greater than half the circumference of the side surface of the cup body 11, and its width is no greater than the width of the side surface of the cup body 11.

[0091] The above method allows for the use of a pen to label the outer wall of the cup 11, facilitating the differentiation of information for urine samples and preventing confusion in recording information while queuing at the sample submission window. It also saves medical staff the need to additionally label the cup 11.

[0092] The various technical features of this utility model are mutually complementary and functionally supportive of each other. In other words, the technical solution is not a "simple superposition" of technical features among multiple prior art documents. Therefore, this utility model does not fall under the category of "simple superposition" in Chapter 4 of Part II of the Patent Examination Guidelines.

[0093] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
