[0002] Before a urine test, a midstream urine sample must be collected. Current urine sampling methods often involve the patient holding a sample cup. This can easily cause urine to splash onto the patient's hands. Furthermore, transporting the sample cup after collection is inconvenient, and urine can easily spill onto the patient's hands. Currently available urine sampling devices that prevent urine from spilling onto hands are typically larger, such as box-shaped devices, to ensure hygienic operation and easy sealing of urine samples.

[0003] In some enterprises, institutions or regions, it is sometimes necessary to provide door-to-door medical examination services. At this time, a mobile medical examination vehicle is needed to provide mobile medical examinations. For mobile medical examinations, the space inside the mobile medical examination vehicle is limited. In order to prevent the examinee from getting their hands dirty when taking or transferring urine samples, it is obviously unrealistic to carry a large number of existing box-shaped sampling devices that are convenient and hygienic for taking urine samples. This results in the examinee still having to use a common sampling cup for sampling during a mobile medical examination. The sampling process is inconvenient and unhygienic. Therefore, there is an urgent need for a mobile medical examination sampling device that does not take up space when carried, can effectively prevent the examinee from getting his hands dirty when in use, and is convenient for the examinee to take and transfer urine samples after taking an appropriate amount of mid-stream urine sample.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-9 As shown, the present invention provides a mobile physical examination sampling device, comprising:

[0032] An L-shaped frame 1, a handle 3 is provided on one side of the L-shaped frame 1, a rotating assembly is provided between the handle 3 and the L-shaped frame 1, and a rotating bracket portion is provided on the other side of the L-shaped frame 1;

[0033] A diversion unit is detachably disposed between the rotating bracket portion and the L-shaped frame 1 and is used to receive and guide the flow of urine;

[0034] The collecting unit is detachably mounted on the L-shaped frame 1 and is connected to the middle portion of the diversion unit for collecting and discharging the midstream urine sample;

[0035] The flow limiting unit is arranged between the bottom of one side wall of the L-shaped frame 1 and the handle 3. The tail end of the guide unit is arranged corresponding to the flow limiting unit to control the middle urine to flow into the collection unit.

[0036] The L-shaped frame 1 mainly serves as a connection, providing a fixed foundation for the various parts of the sampling device; the main function of the handle 3 is to provide a structure for the examiner to hold and operate when taking samples; the main function of the rotating component is to adjust the angle between the handle 3 and the L-shaped frame 1, so that different examiners can find a comfortable use angle; the main function of the rotating bracket part is to provide a placement position for the diversion unit during sampling, and it can be rotated to reduce the occupied space when not in use; the main function of the diversion unit is to guide the urine to flow in a specific direction and prevent urine from splashing when the examiner obtains the urine sample, and it can be conveniently wrapped and stored before use to reduce the occupied space; the main function of the collection unit is to collect the mid-stream urine sample and avoid spillage, and it can be folded and placed before use to reduce the occupied space; the main function of the flow limiting unit is to facilitate the discharge of front-end urine and rear-end urine through the diversion unit through operation, and the mid-stream urine can enter the collection unit, thereby achieving hygienic and convenient acquisition of mid-stream urine samples. On the whole, the present invention can be folded and stored before use, does not occupy a large amount of space, and is convenient for carrying in large quantities during mobile physical examinations; at the same time, when in use, it can effectively prevent urine from splashing onto the hands of the physical examination personnel, achieving clean and hygienic operation, and can conveniently receive mid-stream urine samples, and the intercepted urine samples will not spill when taken and transferred.

[0037] To further optimize the solution, the rotating bracket part includes a supporting ring 2, and the outer side of the supporting ring 2 is fixedly connected to a connecting shaft 6, which is rotatably connected to the top of the side wall of the L-shaped frame 1. Two groups of grooves are provided in the connecting shaft 6, and steel balls 7 are respectively slidably connected in the two groups of grooves. A first spring 8 is abutted between the steel balls 7 and the bottom of the grooves. Two groups of pits 27 are provided on the side wall of the L-shaped frame 1, and the two groups of steel balls 7 are respectively arranged corresponding to the side wall of the L-shaped frame 1 or the two groups of pits 27.

[0038] Before use, support ring 2 is rotated so that it is flush with the long side of the L-shaped frame 1, aligning them roughly in the same plane. This prevents the plane of support ring 2 from being perpendicular to the L-shaped frame 1, thus reducing the space occupied. During use, support ring 2 is rotated, which drives connecting shaft 6. As connecting shaft 6 rotates, the two sets of steel balls 7 within it rotate around the axis of connecting shaft 6. When support ring 2 is rotated to a position perpendicular to the L-shaped frame 1, the two sets of steel balls 7, pushed by the elastic force of the two sets of first springs 8, partially embed themselves in recesses 27, thereby creating a certain resistance to the rotation of connecting shaft 6 and preventing support ring 2 from freely dangling during use.

[0039] To further optimize the solution, the diversion unit includes a collecting cup 9, which is adapted to the support ring 2. The bottom of the collecting cup 9 is connected to one end of a conduit 10, and the other end of the conduit 10 is arranged corresponding to the current limiting unit. A fixed sleeve 14 is provided in the middle of the conduit 10, and a branch pipe 11 is fixedly passed through the top of the fixed sleeve 14. One end of the branch pipe 11 is connected to the conduit 10, and the other end of the branch pipe 11 is arranged corresponding to the collecting unit. Two groups of first fixing rings 15 are fixedly connected to the top of the fixed sleeve 14, and two groups of first fixing rods 16 are fixedly connected to the bottom of the side wall of the L-shaped frame 1. The two groups of first fixing rings 15 are respectively arranged corresponding to the two groups of first fixing rods 16.

[0040] Before use, the catheter 10 and branch tube 11 are wrapped around and stored in the collection cup 9, effectively reducing the occupied area. The wide-mouthed collection cup 9 effectively reduces urine splashing during collection. The branch tube 11 is connected to the top of the catheter 10, ensuring that urine does not enter the branch tube 11 when the catheter 10 is flowing smoothly.

[0041] After the support ring 2 is rotated into place, the conduit 10, the fixing sleeve 14 and the branch pipe 11 are spread out and inserted from the top of the support ring 2, so that the collecting cup 9 is placed on the support ring 2, and then the two groups of first fixing rings 15 on the fixing sleeve 14 are hung on the two groups of first fixing rods 16 to fix the conduit 10 on the L-shaped frame 1, while ensuring that the liquid inlet end of the branch pipe 11 is above the conduit 10.

[0042] To further optimize the solution, the collection unit includes a corrugated cup 12, and the top and bottom of the corrugated cup 12 are respectively provided with a liquid inlet 20 and a liquid outlet 19, the liquid inlet 20 is connected to the end of the branch pipe 11 away from the fixed sleeve 14, and the liquid outlet 19 is connected to the sample discharge valve 13, the top of the corrugated cup 12 is fixedly connected to the second fixing ring 17, the bottom of the side wall of the L-shaped frame 1 is fixedly connected to the second fixing rod 18, and the second fixing ring 17 is respectively arranged corresponding to the second fixing rod 18.

[0043] The sample discharge valve 13 is equipped with a twistable switch. Only when it is turned on can the urine sample flow through the valve 13. The sidewalls of the bellows cup 12 are designed to be foldable and corrugated, allowing them to be collapsed into a thinner shape before use, thus reducing the space occupied. During use, the bellows cup 12 is stretched, the liquid inlet 20 is connected to the branch pipe 11, the sample discharge valve 13 is connected to the liquid outlet 19, and the second fixing ring 17 is hung on the second fixing rod 18 to secure the bellows cup 12.

[0044] A further optimized solution is provided, in which the current limiting unit includes a current limiting shell 28 fixedly connected to one side of the bottom of the L-shaped frame 1, and openings are respectively provided on the two opposite side walls of the current limiting shell 28. The tail end of the conduit 10 passes through the two groups of openings, and two groups of second slide grooves 30 are respectively provided on the two opposite side walls on the inner side of the current limiting shell 28. The two groups of second slide grooves 30 are opened along the extension direction of the conduit 10. The distance between the end of the two groups of second slide grooves 30 away from the fixed sleeve 14 and the conduit 10 is greater than the distance between the end of the second slide groove 30 close to the fixed sleeve 14 and the conduit 10. A sliding roller portion is provided between the two groups of second slide grooves 30, and the conduit 10 is correspondingly provided between the sliding roller portion and the inner wall of the current limiting shell 28, and a control portion is provided between the sliding roller portion and the handle 3.

[0045] A further optimized solution is that the roller part includes a force frame 22 that is slidably connected between the two groups of second slide grooves 30, and a roller 21 is rotatably connected inside the force frame 22. The roller 21 is arranged corresponding to the conduit 10. The roller 21 is used to squeeze the conduit 10 to play a flow limiting role. A second spring 29 is fixedly connected between the force frame 22 and the end of the two groups of second slide grooves 30 away from the fixed sleeve 14, and the control part is arranged between the force frame 22 and the handle 3.

[0046] The roller slides within the second chute 30 under the restraint of the force-bearing frame 22. Pulled by the second spring 29, the force-bearing frame 22, when not in use, is always located at the end of the second chute 30 away from the fixed sleeve 14. Because the distance between the end of the second chute 30 fixing spring and the catheter 10 is greater than the distance between the end without the fixed spring, the roller 21 does not come into contact with the catheter 10 when the catheter 10 passes through the flow-limiting housing 28, allowing the catheter 10 to pass smoothly and urine to flow smoothly within it. When the force-bearing frame 22 is moved toward the other end of the second chute 30 by the operating unit, the roller 22 rolls on the catheter 10 while simultaneously squeezing the catheter 10 against the inner wall of the flow-limiting housing 28, reducing the cross-sectional area of ​​the catheter 10 and increasing the resistance to urine flow. At this point, a portion of urine flows from the branch pipe 11 into the ripple cup 12, thereby achieving the collection of mid-section urine samples.

[0047] A further optimized solution is that the control part includes a first slide groove 26 opened on the side wall of the handle 3, a slider 25 is slidably connected in the first slide groove 26, a sheath 24 is fixedly connected to the outer wall of the L-shaped frame 1 and the handle 3, a pull rope 23 is slidably passed through the sheath 24, one end of the pull rope 23 is fixedly connected to the slider 25, and the other end of the pull rope 23 passes through the side wall of the current limiting shell 28 and is fixedly connected to the end of the force frame 22 away from the second spring 29.

[0048] When it is necessary to collect a midstream urine sample, the thumb is used to move the slider 25 away from the L-shaped frame 1. The slider 25 slides in the chute 26 and pulls the pull rope 23. The pull rope 23 is subjected to tension, pulling the force frame 22 in the second chute 30 to slide toward the fixed sleeve 14, driving the roller 21 to roll on the catheter 10 and squeeze the catheter 10. As the force frame 22 slides, it stretches the two sets of second springs 29. When the urine is collected, the slider 25 is released. The force frame 22 moves in the opposite direction under the pull of the two sets of second springs 29, driving the roller 21 away from the catheter 10. At the same time, the slider 25 is reset by pulling the pull rope 23. As the roller 21 moves away from the catheter 10, the flow resistance of the catheter 10 is reduced, and urine flows out of the catheter 10 again.

[0049] According to a further optimized solution, the rotating assembly includes an outer frame 4 fixedly connected to the side wall of the L-shaped frame 1 , a rotating shaft 5 is vertically rotatably connected inside the outer frame 4 , and one end of the handle 3 is fixedly connected to the outer wall of the rotating shaft 5 .

[0050] The outer frame 4 and the rotating shaft 5 are overfitted, requiring a certain torque for the rotating shaft 5 to rotate within the outer frame 4. This ensures that the handle 3 does not rotate freely after adjusting the angle between it and the L-shaped frame 1. When not in use, the handle 3 can be rotated parallel to the L-shaped frame 1 to reduce space occupation.

[0051] The working process of this embodiment is as follows: when not in use, the handle 3, L-shaped frame 1 and support ring 2 are adjusted to be located in the same plane, the catheter 10 and a part of the branch tube 11 are wrapped and placed in the collection cup 9, and the corrugated cup 12 is contracted into a flat shape. The above can greatly reduce the space occupied by the sampling device, thereby facilitating large-scale carrying on the mobile medical examination vehicle.

[0052] During use, the medical examiner rotates the support ring 2 to the horizontal turntable, spreads out the catheter 10 and the branch pipe 11 and passes them through the top of the support ring 2, places the collection cup 9 in the support ring 2, passes the free end of the catheter 10 through the flow limiting shell 28, fixes the fixed sleeve 14 on the L-shaped frame 1 through the first fixing rod 16, then stretches the corrugated cup 12, connects the branch pipe 11 with the liquid inlet 20 at the top of the corrugated cup 12, connects the sample discharge valve 13 with the liquid outlet 19, and fixes the corrugated cup 12 on the L-shaped frame 1 through the second fixing rod 18 for use.

[0053] During use, the user holds the handle 3, and urine flows through the collection cup 9 into the catheter 10 and out through the tail end of the catheter 10. After a certain period of urination, the user pulls the slider 25 backward with the thumb. The slider 25, through the pull rope 23 and the force-bearing frame 22, drives the roller 21 to roll on the catheter 10 and squeeze the catheter 10, increasing the flow resistance of the catheter 10. At this point, some urine flows through the branch tube 11 into the corrugated cup 12, collecting the urine at the middle end. After a certain amount of urine has been collected, the slider 25 is released, and the roller 21 returns to its original position under the elastic force of the second spring 29. The catheter 10 is no longer squeezed, and the flow is smooth, allowing the remaining urine to continue to flow out of the catheter 10.

[0054] After collecting the urine sample, the corrugated cup 12 is removed from the branch tube 11 and can be transferred by hand, reducing the risk of spilling the urine sample. When the medical staff needs to remove the urine sample, they simply unscrew the sample valve 13 to drain the urine sample into the branch tube. The collection cup 9, catheter 10, branch tube 11, and fixed sleeve 14 are disposable and inexpensive. After use, the examinee can simply discard them and return the remaining components.
