Description

Technical Field

[0001] The present invention relates to the technical field of medical nursing devices, and more specifically, to a urine collection device for pediatric critical care nursing. Background Art

[0002] Critically ill children cannot get out of bed to urinate and need to use a urine collection device to collect urine. The existing bedpans used by female patients are all squat bedpans, which require them to sit up to urinate. For critically ill bedridden girls, there are many tubes, unstable vital signs, and children unwilling to cooperate. The comfort and compliance during use are poor, which can also cause changes in vital signs and tube detachment, aggravating the condition. In clinical work, it is generally difficult for girls to collect urine for testing. Urine and feces may be mixed together, and the urine volume is uncertain, which affects the observation of urine properties and urine collection and testing. The existing urine collection device is placed near the genitals for collection, and only urine is collected to prevent the problem of urine and feces mixing, which is convenient for collecting urine for testing. At the same time, whenever urination is needed, nursing staff needs to operate to allow urine to enter the urine bag along the tube for collection, avoiding the problem of tube detachment caused by inserting a catheter.

[0003] However, since children cannot stand up, the opening of the male urine collecting funnel is tilted downward, and part of the urine is likely to flow along the collecting funnel to the surface of the human body when collecting urine. Female patients are likely to leak urine behind their backs and around their thighs, resulting in incomplete urine collection and easy soiling of the body and clothes. The urine needs to be tested after collection, and since the existing male portable urinals and female squatting potties do not have accurate scales, the nurse needs to weigh the urine manually after collecting it and then pour it out, which greatly increases the workload of the nursing staff. At the same time, the urine collection tube is relatively small, and directly using the collection tube to collect urine is likely to cause the collection tube to be overfilled and cause urine overflow. Only part of the urine can be collected on the urine bag using the collection tube. Since the connection between the collection tube and the urine is a threaded connection, the urine in the urine bag is likely to flow out when the collection tube is detached, causing the problem of urine overflowing during collection.

Beneficial Effects

[0010] 1. In the present invention, when collecting urine for testing, the collection tube is manually rotated, so that the collection tube is rotated and moved upward on the outer side of the fixed tube, and then the collection tube is rotated and moved on the outer side of the threaded tube, pushing the limiting mechanism to translate in the square groove on the side of the arc plate.

The elastic deformation of the block avoids the situation where a gap is generated after the collection is completed to cause urine leakage, and at the same time prevents the problem of urine overflowing easily during collection.

[0012] 3. When the receiving bucket of the present invention receives urine, the soft strip is placed near the child's genitals, and the urine is splashed irregularly due to the friction of the buffer plate to destroy the impact elasticity of the urine, so that the urine will not splash and flow out along the plastic tube on the lower side of the buffer plate, and the urine is blocked by the blocking strip to prevent the urine from flowing toward the soft strip and entering the human skin surface, thereby preventing the body from being soiled due to incomplete urine collection during urination.

The upper end of the diversion tube 4 is connected to the lower end of the collection bucket 6, and the lower end of the diversion tube 4 is interference-fitted with the upper end of the urine bag 2. The collector 3 is embedded in the side of the urine bag 2, the urination tube 5 is installed at the lower end of the urine bag 2, the hook 1 is embedded in the upper end of the urine bag 2, and the collector 3 is provided with a fixing tube 31 and a supporting block 32. , a limiting mechanism 33, and a collection tube 34. The support block 32 is embedded in the inner side of the fixed tube 31. The lower end of the limiting mechanism 33 is installed on the upper end of the support block 32. The outer side of the limiting mechanism 33 is embedded in the inner side of the fixed tube 31. The collection tube 34 is movably matched with the outer thread of the fixed tube 31. The upper end of the collection tube 34 is located below the outer end of the limiting mechanism 33. The upper end of the fixed tube 31 is embedded in the side of the urine bag 2. A circular The groove has the effect of circulating urine. The collector 3 is located at the lower half of the urine bag 2. The urine bag 2 is transparent and square, not easy to deform. The outer surface of its side is provided with scale lines, which has the effect of observing the urine content. Therefore, the receiving bucket 6 is placed on the child's genitals, and the urine flows from the receiving bucket 6 to the diversion tube 4 into the urine bag 2, and can be discharged from the urine bag 2 through the urination tube 5. When detecting urine, the urine bag 2 is turned over to make the urine flow to the collector 3 to collect urine. At the same time, the urine bag 2 is hung by the hook 1, and the collection tube 34 is manually rotated during urine detection and collection, so that the collection tube 34 is rotated and moved on the outer thread of the fixed tube 31, and then the limiting mechanism 33 is disengaged from the pressing of the support block 32, so that a gap is generated between the limiting mechanism 33 and the support block 32, and the urine flows from the fixed tube 31 to the gap between the limiting mechanism 33 and the support block 32 to the collection tube 34, so as to realize the collection and detection of urine and avoid leakage of urine during collection.

[0023] Among them, the limiting mechanism 33 is provided with a movable plate w1, a force-bearing plate w2, a rubber sleeve w3, a sealing ring w4, a connecting ring w5, and a spring rod w6.

In order to achieve the effect, six spring rods w6 are arranged, which are evenly distributed in a ring shape with the movable plate w1 as the center, so that the force-bearing plate w2 is pushed upward by the collection tube 34, and at the same time, the spring rod w6 is stretched, and the sealing ring w4, the connecting ring w5 and the rubber sleeve w3 form a pipeline effect, so that urine will not leak out when the force-bearing plate w2 moves upward, and then the lower end of the movable plate w1 is separated from the circular groove in the middle of the support block 32 to form a gap, so that urine flows out from the circular groove. After releasing the pressure of the collection tube 34, the spring rod w6 moves downward elastically, so that the movable plate w1 squeezes the circular groove of the support block 32 again, thereby forming a barrier to the urine. At the same time, the collection tube 34 rotates and moves to control the size of the urine flowing out of the gap, and at the same time prevents the problem of urine overflowing easily during collection.

[0024] Among them, the movable plate w1 is provided with a circular plate w11, a block w12, and a circular hole w13. The block w12 is embedded in the side surface of the lower end of the circular plate w11, and the circular hole w13 is located inside the circular plate w11. The circular plate w11 is installed on the inner side of the connecting ring w5. There are eight circular holes w13, which are evenly distributed in a ring with the circular plate w11 as the center. The block w12 is made of rubber and has the effect of extrusion elastic deformation. Therefore, when the circular plate w11 is separated from the contact with the support block 32, urine flows from the circular hole w13 to the bottom of the movable plate w1 and flows out from the middle of the support block 32. When the circular plate w11 follows the connecting ring w5 and is driven by the force plate w2 to move downward, the block w12 squeezes the middle of the support block 32 to form a barrier to urine, and avoids the situation where a gap is generated after the collection is completed and urine leaks out under the elastic deformation of the block w12.

[0025] The fixed tube 31 is provided with an arc plate t1, a square groove t2, a threaded tube t3, and a fixed block t4. The fixed block t4 is embedded in the side of the arc plate t1. The square groove t2 is located on the side of the arc plate t1. The arc plate t1 is installed on the side of the threaded tube t3. The outer side of the limiting mechanism 33 is embedded in the side of the threaded tube t3. The collection tube 34 is movably matched with the outer thread of the threaded tube t3. The support block 32 is embedded in the inner side of the threaded tube t3. The inner side of the limiting mechanism 33 is fixed to the outer side of the threaded tube t3. The sealing ring w4 is embedded in the inner side of the fixed block t4. There are six square grooves t2, which are evenly distributed in a ring shape, so that the collection tube 34 rotates and moves on the outside of the threaded tube t3, pushing the limiting mechanism 33 to translate in the square groove t2 on the side of the arc plate t1. At the same time, the sealing ring w4 is connected to the inner side of the fixed block t4 and extends to the force-bearing plate w2, so that the square groove t2 is located on the outside of the sealing ring w4, forming a sealed state in the arc plate t1, preventing a gap from being generated in the fixed tube 31 when the limiting mechanism 33 is active. The specific usage and function of this embodiment are as follows: In the present invention, the receiving bucket 6 is placed at the child's genitals, and urine flows from the receiving bucket 6 to the diversion tube 4 into the urine bag 2, and can be discharged from the urine bag 2 through the urination tube 5. When testing urine, the urine bag 2 is turned over to allow the urine to flow to the collector 3 to collect urine. At the same time, the urine bag 2 is hung by the hook 1, and the collecting tube 34 is manually rotated during urine testing and collection, so that the collecting tube 34 is threadedly rotated and moved upward on the outer side of the fixed tube 31, and then the collecting tube 34 is rotated and moved on the outer side of the threaded tube t3, pushing the limiting mechanism 33 to translate in the square groove t2 on the side of the arc plate t1, and at the same time, the sealing ring w4 is connected to the inner side of the fixed block t4 and extends to the force plate w2, so that the square groove t2 is located on the outer side of the sealing ring w4, forming a sealed state in the arc plate t1, preventing the limiting mechanism 33 from generating a gap in the fixed tube 31 when it moves, and providing space for the movement of the limiting mechanism 33.

[0026] In the present invention, the force plate w2 in the limiting mechanism 33 is pushed upward by the collection tube 34, and at the same time, the spring rod w6 is stretched, and the sealing ring w4, the connecting ring w5 and the rubber sleeve w3 form a pipeline effect, so that urine will not leak out when the force plate w2 moves upward, and then the lower end of the movable plate w1 is separated from the circular groove in the middle of the support block 32 to produce a gap, and when the circular plate w11 in the movable plate w1 is separated from the contact with the support block 32, urine flows from the circular hole w13 to the bottom of the movable plate w1 and flows out from the middle of the support block 32, and the urine flows out from The fixed tube 31 flows into the collection tube 34 through the gap between the limiting mechanism 33 and the support block 32 to realize the collection and detection of urine. When the circular plate w11 follows the connecting ring w5 and is driven by the force plate w2 to move downward, the block w12 squeezes the middle of the support block 32 to form a barrier to the urine. The elastic deformation of the block w12 avoids the situation where a gap is generated after the collection is completed to cause urine leakage. The size of the urine flowing out of the gap is controlled by rotating the collection tube 34, and the problem of urine overflowing during collection is prevented. Example

When the urine is tilted backward, the upper end of the soft strip e1 is pressed to reduce the space above the urine outlet, so that the urine tilting backward is blocked and guided forward, avoiding the urine tilting backward when the female patient is lying down, so that the soft strip e1 contacts the vicinity of the child's genitals and is in a downward tilted state, which is suitable for children of different genders, and the urine flows to the buffer plate e5 on the inner side of the arc cover e4. Under the friction of the buffer plate e5, the urine splashes irregularly to destroy the impact elastic force of the urine, so that the urine will not splash and flow out along the buffer plate e5 to the plastic tube e2 on the lower side, and the urine is blocked by the blocking strip e3, so that the urine accumulates at the outlet of the plastic tube e2, and at the same time, it is avoided that the urine flows in the direction of the soft strip e1 and enters the human skin surface.

[0028] The blocking strip e3 is provided with an inclined plate e31, a closed plate e32, and a hole e33. The closed plate e32 is embedded in the side of the inclined plate e31. The hole e33 is located in the middle of the inclined plate e31. The inclined plate e31 is embedded in the inner side of the arc cover e4. An opening structure is provided inside the lower end of the closed plate e32, and the closed plate e32 and the inclined plate e31 form a triangle state, so that urine enters the side of the inclined plate e31 from the lower end opening structure of the closed plate e32 along the buffer plate e5, and then When the arc cover e4 tilts downward, the top angle formed by the inclined plate e31 and the closed plate e32 points downward, which can collect urine. When the urine reaches a certain amount, it moves from the hole e33 in the inclined plate e31 to the next layer of blocking strip e3, achieving a multi-layer urine blocking effect. At the same time, after urination, the soft strip e1 flips upward, so that the urine flows out from the inclined plate e31 along the inner side of the arc cover e4 to the plastic tube e2 again, achieving a limited urine blocking effect, preventing the body from being soiled due to incomplete urine collection during urination. The specific usage and function of this embodiment are as follows: In the present invention, when the receiving bucket 6 receives urine, the soft strip e1 is placed near the child's genitals, in a downward tilted state to contact the human skin, and then it is suitable for children of different genders, and the urine flows onto the buffer plate e5 on the inner side of the arc cover e4, and the urine is irregularly splashed under the friction of the buffer plate e5 to destroy the impact elasticity of the urine, so that the urine will not splash and flow out along the buffer plate e5 to the plastic tube e2 on the lower side, and the urine is blocked by the blocking strip e3, so that the urine accumulates at the outlet position of the plastic tube e2, and the urine enters the inclined plate e31 from the lower end opening structure of the closed plate e32 along the buffer plate e5.
