Description

Technical Field

[0001] The invention relates to the technical field of clinical detection, in particular to a bedside urine volume counting device with accumulation and alarm functions. Background Art

[0002] Urine volume testing is an important clinical tool for assessing kidney function, diagnosing diseases, and monitoring fluid balance. Currently, urine containers are marked with volumetric scales and are made of transparent materials. Medical staff and family members estimate the volume of urine in the container by reading the scale. During 24-hour urine volume measurement, family members typically record the amount of urine in the container at regular intervals and promptly inform the nurse. This process is cumbersome and inconvenient, and prone to errors and omissions. Furthermore, urine containers have a limited total volume. Once a patient's urine volume approaches the container's capacity, it is necessary to empty the container completely to allow for the next urine output. This creates a lot of hassle for family members, making it more likely that errors will occur during urine volume measurement. Urine bags are commonly used as containers for urine. These bags are often made of plastic, and the horizontal cross-section of each part varies when filled. This cross-section also changes with the amount of urine contained. This makes estimating the urine volume in the bag more difficult, hindering urine volume measurement. To address this issue, existing methods typically use load cells or weighing modules to measure urine volume over a 24-hour period, such as the fully automatic urine volume meter patented with authorization publication number CN211022717U. However, these load cells or weighing modules measure the urine bag in real time, requiring medical staff or family members to press a button to begin accumulation. This button can be easily forgotten in a hurry. Furthermore, these fully automatic urine volume meters lack the necessary alarms to alert patients of excessive urine in the bag and the need to drain it promptly, increasing the likelihood of errors by medical staff or family members. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems and provide a bedside urine volume counting device with accumulation and alarm functions.

[0004] The technical solution of the present invention is: a bedside urine volume counting device with accumulation and alarm functions includes a hook structure sliding system, an outer shell, a weighing spring, a metering component, and an alarm component; a hook structure is provided at the lower end of the hook structure sliding system for hanging a urine bag; the upper end of the hook structure sliding system is vertically slidably connected to the outer shell to limit the sliding direction of the hook structure sliding system; the upper end of the weighing spring is connected to the upper end of the outer shell, and the lower end is connected to the lower end of the hook structure sliding system; similar to a common spring scale, the weight of the urine bag can be converted into the expansion and contraction of the weighing spring and the vertical displacement of the hook structure sliding system; a metering rack is provided on the left side of the hook structure sliding system, which runs through the upper and middle parts of the hook structure sliding system; a vertical alarm is provided on the upper right side of the hook structure sliding system Alarm rack; a vertical plane that does not exceed the root of the alarm rack extends outward from the middle and lower right side of the hook structure sliding system, which is used to isolate gear B in the non-alarm area; the metering component and the alarm component are respectively arranged on the left and right sides of the outer shell; the vertically sliding hook structure sliding system acts on the metering component and the alarm component respectively through the metering rack and the alarm rack; the metering component includes gear A, drive shaft A, pointer, metering ring, and one-way mechanism; gear A is meshed with the metering rack and is coaxially installed on the drive shaft A through the one-way mechanism; the gear A can be driven to rotate by the metering rack; the rotating gear A drives the drive shaft A to rotate as appropriate; the end of the drive shaft A is rotatably connected to the outer shell to achieve stable positioning of the drive shaft A and gear A relative to the outer shell, ensuring that the gear A and the meter The measuring rack is stably engaged; one end of the driving shaft A extends beyond the outer shell and drives the connecting pointer; the driving shaft A drives the pointer to rotate; the surface of the metering ring is engraved with a metering scale, which is installed on the outer shell and cooperates with the pointer; the pointer points to the metering scale and accumulates the weight hung by the hook structure; the alarm component includes gear B, driving shaft B, a sound cylinder and a sound bar; gear B is engaged with the alarm rack and is coaxially installed on the driving shaft B; the alarm rack can drive gear B to rotate; the rotating gear B drives the driving shaft B to rotate as needed; the end of the driving shaft B is rotatably connected to the outer shell to achieve stable positioning of the driving shaft B and gear B relative to the outer shell, ensuring that gear B can stably cooperate with the alarm rack; one end of the driving shaft B extends beyond the outer shell and drives the connecting sound cylinder; the driving shaft B drives The sound cylinder rotates; the outer wall of the sound cylinder is regularly provided with protrusions; the sound bar is installed on the outer shell and cooperates with the protrusions; the rotating sound cylinder acts on the sound bar through the protrusions, and regularly emits music to achieve an alarm effect; the sliding system of the hook structure descends, bringing the metering rack down; the metering rack descends, driving the gear A to rotate; the rotating gear A drives the one-way mechanism to rotate; the rotation of the one-way mechanism drives the driving shaft A to rotate; the urine bag is hung on the hook structure, and as the urine in the urine bag increases, the sliding system of the hook structure pulls the weighing spring downward due to the increase in the gravity of the urine in the urine bag, and at the same time the hook structure gradually descends; the descending sliding system of the hook structure causes the metering rack to move vertically downward; the vertically downward moving metering rack acts on the pointer through the gear A to rotate the pointer to a certain angle;The angle of rotation of the pointer corresponds to the increase of urine in the urine bag; the measurement scale on the measurement ring pointed by the pointer represents the cumulative measurement of urine in the urine bag; when the urine in the urine bag accumulates to a certain amount and pulls the hook structure to descend to the preset alarm position, the alarm rack falls to the same height position with gear B along with the hook structure sliding system; after the alarm rack contacts with gear B, with the continuous downward movement of the alarm rack, gear B is driven to rotate by the alarm rack; the rotating gear B drives the sound emitting cylinder to rotate through the driving shaft B; the sound emitting cylinder acts on the sound emitting strip to make the sound emitting strip emit music to play a warning role; when people hear the music, they will know that the urine in the urine bag accumulates to a certain amount and needs to be discharged in time; with the discharge of urine in the urine bag, the weight on the hook structure decreases (it may be to take off the urine bag, pour out the urine, or it may be to keep the urine bag hanging on the hook structure, use the urine discharge pipe with valve on the urine bag to discharge urine), under the elastic force of the weighing spring, the hook structure sliding system is pulled to vertically rise; the vertically rising hook structure sliding system drives gear A to rotate through the measurement rack; but because of the existence of the one-way mechanism, driving shaft A does not rotate with gear A; in this way, the direction indicated by the pointer does not change and will not rotate; therefore, the measurement scale pointed by the pointer can measure the cumulative weight in the urine bag. When pouring the urine bag to discharge urine, an alternative that is not heavier than the weight of the poured urine needs to be hung on the hook structure to avoid the rotation of the pointer caused by the re-hanging of the urine bag after the urine bag is poured to discharge urine.

[0005] Preferably, when the hook structure sliding system rises, the alarm rack also drives the sound emitting cylinder to rotate, causing the sound emitting strip to mistakenly emit music and causing interference; the one-way mechanism includes a one-way bearing; gear A and gear B are connected with driving shaft A and driving shaft B through the one-way bearing, thereby realizing the one-way transmission at gear A and gear B. In this way, when the hook structure sliding system rises, the sound emitting strip will not emit any sound.

[0006] Preferably, the one-way mechanism can realize one-way transmission of force or torque; but in actual operation, any one-way mechanism will transmit an inconsistent force or torque due to inertia when subjected to a reverse force or torque; this inconsistent force or torque will cause slight shaking of the pointer, which is not conducive to the accurate indication of the measurement scale by the pointer; to solve this problem, the pointer is also provided with an adjustment starting torque mechanism cooperating with the one-way mechanism; the adjustment starting torque mechanism can set the starting torque of the pointer rotation to resist the inconsistent force or torque; such a setting is easy to cause errors in the weighing of the urine bag, i.e. when the hook structure sliding system is weighed, the starting torque will bear the urine bag gravity together with the spring force of the weighing spring, so that there is a fixed deviation between the measurement scale indicated by the pointer and the actual volume of the urine bag, which can be solved by adjusting the measurement scale reading; in addition, only when the amount of urine in the urine bag exceeds a certain value, the pointer can rotate; but this has little effect on 24-hour urine volume detection, and no error is generated when the urine bag is hung on the hook structure again after being taken down to pour out the urine.

[0007] Further, the adjustment starting torque mechanism includes a tapered roller bearing with adjusted play; the inner ring of the tapered roller bearing is coaxially fixed with the pointer; the outer ring of the tapered roller bearing is mounted on the outer shell; there are various methods for adjusting the play of the tapered roller bearing, including push-pull method, adjusting gasket thickness method, nut adjustment method, screw cover adjustment method, Acro-Set method, Torque-Set method, Projecta-Set method, Set-Right method; according to the needs and actual conditions, the tapered roller bearing selects the corresponding play adjustment method.

The starting torque of the pointer is changed by replacing the rubber pad with different thickness.

[0009] Further, the adjustment starting torque mechanism comprises an adjusting screw, a rubber round pad, the adjusting screw is provided with an annular clamping groove at the root, the rubber round pad is sleeved in the clamping groove, the adjusting screw is threadedly connected with the rear end of the pointer shaft, and the rubber round pad is matched with the outer ring of the pointer bearing. After the bedside urine volume counting device is used for a period of time, the rubber pad will be worn out, and it is difficult to ensure the starting torque of the pointer. The starting torque of the pointer is adjusted by adjusting the compression force of the rubber round pad on the pointer bearing through the adjusting screw. The adjustment process is as follows: the adjusting screw is intermittently tightened; the number of turns is the same each time, and after each tightening, the hook structure sliding system is pulled down, and the pointer is observed; if the pointer rotates when the hook structure sliding system is pulled down, and the pointer does not rotate when the hook structure sliding system returns, it means that the starting torque of the pointer is adjusted.

[0010] Further, the one-way mechanism comprises an internal meshing ratchet, a pawl, a coaxial bearing and a spring; a part of the gear A is coaxially connected with the driving shaft A through the coaxial bearing, so that the gear A and the driving shaft A are in coaxial state; another part of the gear A is connected with the internal meshing ratchet and moves with the internal meshing ratchet; the pawl is distributed around the driving shaft A in a circle; a part of the pawl is hinged with the driving shaft A and can swing relative to the driving shaft A; another part of the pawl is connected with the driving shaft A through the spring, so that the pawl can be reset.

[0011] Preferably, the outer shell comprises a front plate, a rear plate, a front-rear plate support sleeve, a mounting bolt and a mounting nut; the front plate and the rear plate are coincident front and rear; the mounting bolt is sequentially threaded through the front plate, the front-rear plate support sleeve, the rear plate and threadedly matched with the mounting nut; the outer shell establishes a basic frame to facilitate the installation of the metering assembly and the alarm assembly; the front plate is provided with a front sliding groove in the middle lower part; the rear plate is provided with a rear sliding groove in the middle lower part; the front-rear direction of the hook structure sliding system is respectively provided with a front sliding strip and a rear sliding strip; the front sliding strip is slidably matched with the front sliding groove; the rear sliding strip is slidably matched with the rear sliding groove; the vertical sliding of the hook structure sliding system is guided.

[0022] Example 1: See Figures 1-10The application discloses a bedside urine volume counting device with accumulation and alarm functions, which comprises a hook structure sliding system, an outer shell, a weighing spring 3, a metering assembly and an alarm assembly.The one-way mechanism rotates with the driving shaft A 42; the urine bag is hung on the hook structure 111, as the urine in the urine bag increases, the hook structure sliding system is pulled downward by the increasing gravity of the urine in the urine bag, and the hook structure 111 gradually descends; the descending hook structure sliding system moves the measurement rack 12 vertically downward; the vertically downward movement of the measurement rack 12 drives the pointer 43 to rotate by a certain angle through the gear A 41; the angle of rotation of the pointer 43 corresponds to the increase of the urine in the urine bag; the measurement scale 441 on the measurement ring 44 pointed by the pointer 43 represents the cumulative measurement of the urine in the urine bag; when the urine in the urine bag accumulates to a certain amount and the hook structure 111 descends to the preset alarm position, the alarm rack 13 falls to the same height position as the gear B 51 with the hook structure sliding system; after the alarm rack 13 contacts the gear B 51, the gear B 51 is driven to rotate by the alarm rack 13 as the alarm rack 13 continues to move downward; the rotating gear B 51 drives the sound emitting cylinder 53 to rotate through the driving shaft B 52; the sound emitting cylinder 53 drives the sound emitting strip 54 to emit music to play a warning role; when people hear the music, they will know that the urine in the urine bag has accumulated to a certain amount and needs to be discharged in time; as the urine in the urine bag is discharged, the weight on the hook structure 111 decreases (it may be that the urine bag is removed, the urine bag is poured to discharge the urine, or the state of hanging the urine bag on the hook structure 111 is maintained, and the urine is discharged through the urine discharge pipe with a valve on the urine bag), and under the elastic force of the weighing spring 3, the hook structure sliding system is pulled to move vertically upward; the vertically upward moving hook structure sliding system drives the gear A 41 to rotate through the measurement rack 12; but because of the one-way mechanism, the driving shaft A 42 does not rotate with the gear A 41; in this way, the direction indicated by the pointer 43 does not change and will not rotate; therefore, the measurement scale 441 pointed by the pointer 43 can measure the cumulative weight in the urine bag.

[0034] The working process of the embodiment is as follows: the counting device is hung beside the bed; the urine bag is hung on the hook structure 111; as the urine in the urine bag increases, the hook structure sliding system is pulled downward by the weighing spring 3 due to the increase of the urine gravity, and the hook structure 111 gradually descends; the descending hook structure sliding system vertically moves the measurement rack 12 downward; the vertically downward movement of the measurement rack 12 drives the pointer 43 to rotate by a certain angle through the gear A 41; the rotation angle of the pointer 43 corresponds to the increase of the urine in the urine bag; the measurement scale 441 on the measurement ring 44 pointed by the pointer 43 represents the cumulative measurement of the urine in the urine bag; when the urine in the urine bag accumulates to a certain amount and the hook structure 111 descends to the preset alarm position, the alarm rack 13 falls to the same height position as the gear B 51 with the hook structure sliding system; after the alarm rack 13 contacts the gear B 51, the gear B 51 is driven to rotate by the alarm rack 13 as the alarm rack 13 continuously moves downward; the rotating gear B 51 drives the sound emitting cylinder 53 to rotate through the driving shaft B 52; the sound emitting cylinder 53 drives the sound emitting strip 54 to emit music to play a warning role; when people hear the music, they know that the urine in the urine bag accumulates to a certain amount and needs to be discharged in time; as the urine in the urine bag is discharged, the weight on the hook structure 111 decreases, and the hook structure sliding system is pulled to vertically rise under the elastic force of the weighing spring 3; the hook structure sliding system vertically rises to drive the gear A 41 to rotate through the measurement rack 12; however, the driving shaft A 42 does not rotate with the gear A 41 due to the existence of the one-way mechanism; in this way, the direction indicated by the pointer 43 does not change and the pointer 43 does not rotate; therefore, the measurement scale 441 pointed by the pointer 43 can measure the cumulative weight in the urine bag.

[0035] Zeroing of the pointer 43: the pointer 43 is re-pointed to the measurement scale 441 as zero; currently, there are two methods for zeroing the pointer 43. The first method for zeroing the pointer 43 is to bend the pointer 43 using pliers when the pointer 43 is close to the position of the measurement scale 441 as zero, so that the pointer 43 is pointed to the position of the measurement scale 441 as zero; the second method for zeroing the pointer 43 is to repeatedly pull the hook structure 111; each time the hook structure 111 is pulled downward, the pointer 43 rotates until the pointer 43 is pointed to the position of the measurement scale 441 as zero, and the hook structure 111 is released, thereby completing the zeroing of the pointer 43.

[0036] Embodiment two: Embodiment two is basically the same as Embodiment one, and the same parts will not be repeated. The differences are as follows: the outer shell further comprises a front baffle 27 and a rear baffle 28; the front baffle 27 covers the upper part of the front sliding groove 211; the rear baffle 28 covers the upper part of the rear sliding groove 221; the front baffle 27 and the rear baffle 28 limit the front and rear directions of the hook structure sliding system, improving the stability of the vertical sliding of the hook structure sliding system; the front baffle 27 and the rear baffle 28 are installed on the front plate 21 and the rear plate 22 respectively through bolts and nuts.

[0037] The front plate 21, the front baffle 27, the transmission gear B 46, and the transmission gear A 45 are all transparent materials; the meter ring 44 is pasted on the back of the front plate 21 in a way that the meter scale 441 is in advance.

[0038] Embodiment three: Referring to Figures 11-18 , Embodiment three is basically the same as Embodiment one, and the same parts will not be repeated. The differences are as follows: the adjustment starting torque mechanism comprises a pointer shaft 72, a pointer bearing 73, and a rubber pad 74; the pointer 43 is fixed at the front end of the pointer shaft 72; the pointer bearing 73 and the rubber pad 74 are sleeved on the pointer shaft 72; the pointer shaft 72 has a step 721 in the middle; the step 721 is in contact with the rubber pad 74; the rubber pad 74 is in contact with the inner and outer rings of the pointer bearing 73; the pointer bearing 73 is installed on the outer shell; the thickness of the rubber pad 74 determines the starting torque of the pointer bearing 73 and the pointer shaft 72. By replacing the rubber pad 74 of different thickness, the starting torque of the pointer 43 can be changed.

[0039] The adjustment starting torque mechanism comprises an adjusting screw 75 and a rubber round pad 76; the adjusting screw 75 has an annular clamping groove 751 at the root; the rubber round pad 76 is sleeved in the clamping groove 751; the adjusting screw 75 is threadedly connected with the rear end of the pointer shaft 72; the rubber round pad 76 matches the outer ring of the pointer bearing 73. After the bedside urine volume counting device is used for a period of time, the rubber pad 74 will be worn out, making it difficult to ensure the starting torque of the pointer 43; by adjusting the tightening force of the rubber round pad 76 on the pointer bearing 73 through the adjusting screw, the starting torque of the pointer 43 can be adjusted. The adjustment process is as follows: intermittently tighten the adjusting screw; the number of turns is the same each time, and after each tightening, the hook structure sliding system is pulled down, and the pointer 43 is observed; if the pointer 43 rotates when the hook structure sliding system is pulled down, and the pointer 43 does not rotate when the hook structure sliding system returns, it means that the starting torque of the pointer 43 has been adjusted.

[0040] The one-way mechanism comprises mutually cooperating internal meshing ratchet 82, pawl 83, coaxial bearing 84, spring 85; gear wheel A 41 is coaxially connected with driving shaft A 42 through coaxial bearing 84, which ensures that gear wheel A 41 and driving shaft A 42 are coaxial; the other part of gear wheel A 41 is connected with internal meshing ratchet 82 and moves with internal meshing ratchet 82; pawl 83 is circumferentially distributed around driving shaft A 42; one part of pawl 83 is hingedly connected with driving shaft A 42 and can swing relative to driving shaft A 42; the other part of pawl 83 is connected with driving shaft A 42 through spring 85, so that pawl 83 can be reset.

[0041] The bed-side urine volume counting device with the cumulative and alarm functions further comprises a vertically arranged columnar damper 9; the upper end of the columnar damper 9 is connected with the outer end of the upper spring connecting part 62; the lower end of the columnar damper 9 is connected with the outer end of the connecting block 141. The columnar damper 9 can reduce the vibration caused by the rebound of the hook structure sliding system and improve the indication stability of the pointer 43.
