Description

Technical Field

[0001] The present invention relates to the technical field of neonatal care equipment, and in particular to a urine collecting device for neonatal care. Background Art

[0002] Urine testing of newborns is an important step in neonatal care. It determines the physical condition of the newborn based on the number of red blood cells, white blood cells, urobilinogen, urine ketone bodies, urine specific gravity, and the presence of urine crystals or urine protein. Medical staff usually use urine collection devices to collect newborn urine and then perform urine tests on the collected urine.

[0003] However, it is more difficult to collect urine from newborns. Due to their physiological and age factors, they cannot control urination on their own, which makes collecting urine samples time-consuming and laborious.

[0004] In a urine collection device for neonatal care with application number: CN202110599392.8, a connecting bag with foam adhesive is connected to the urination site of the neonate to collect urine;

[0005] The above-mentioned urine collection device for neonatal care achieves rapid and convenient urine collection, but there are still many deficiencies in the actual use process;

[0006] Because newborns have poor autonomous consciousness, urine collection takes a long time, generally between 1-3 hours. During this period, the newborn's turning over, movement, etc. will cause collision with the connection bag, causing the drainage bag to be separated from the newborn's urination site;

[0007] In addition, during the urine collection process, there are not always family members or medical staff accompanying the newborn. When the newborn urinates, the urine first enters the connecting bag, and the urine is easy to splash and flow back onto the skin around the newborn's urination site, which can easily cause skin allergies and inflammation in infants and young children. In addition, the residual urine penetrates the stability of the foam glue fixation, resulting in the failure of the connection bag fixation.

[0008] Therefore, the present invention proposes a urine collection device for neonatal care to solve the above technical problems. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] A urine collection device for neonatal care, comprising: protective pants, a cover, a catheter, a suction pump, and a urine collection bag;

[0011] The protective pants are provided with a cover body to cover the urination area of ​​the human body; a catheter is provided at the lower end of the cover body to connect to the urine collection bag to realize the transportation and collection of urine; a branch pipe is provided at the lower part of the catheter to connect to the suction pump;

[0012] The cover body is cylindrical, with a hollow cavity formed inside the cover body, and the lower end of the cover body is movably connected to the catheter head end; the upper end of the cover body is provided with an annular groove for installing the absorption layer, and an adhesive layer is provided on the cover body wall around the annular groove;

[0013] The upper portion of the hollow cavity is a cone-shaped cavity that is narrow at the top and wide at the bottom, and the lower portion is a funnel-shaped cavity that is wide at the top and narrow at the bottom; a plurality of anti-slip grooves are arranged in an array on the walls of the cone-shaped cavity and the funnel-shaped cavity; one-way air valves are symmetrically arranged on the walls of both sides of the cone-shaped cavity;

[0014] The upper end of the anti-slip pattern is a semi-cone, and the lower end is a 1 / 4 ring; the apex of the semi-cone faces the upper end of the cover; and the 1 / 4 ring faces the lower end of the cover;

[0015] Furthermore, the protective pants are in the shape of shorts and are made of a soft, skin-friendly and elastic material. The protective pants protect the skin around the neonate's buttocks and urination area, and the elastic protective pants compress the mask body to enhance the stability of the mask body.

[0016] Furthermore, the cover body is made of hard plastic, and the lower end of the cover body is sealed and rotatably connected to the upper end of the conduit;

[0017] Furthermore, the bifurcated pipe is arranged perpendicularly to the conduit, and a wave pipe is provided on the bifurcated pipe to connect to the suction pump;

[0018] A protective bag is provided in the middle of the wave tube to prevent urine from entering the interior of the suction pump;

[0019] Furthermore, the middle of the upper end of the urine collection bag is integrally connected to the lower end of the catheter; the urine collection bag adopts a hard transparent material layer, a capacity scale is set on the front wall of the urine collection bag, and a hook is symmetrically set on the upper rear end of the urine collection bag to be movably connected to the bed;

[0020] Furthermore, the interior of the urine collecting bag is a square cavity of fixed volume, and a floating plate is movably arranged inside the urine collecting bag;

[0021] A square plate with a width equal to the width of the square cavity and a length greater than 3 times the inner diameter of the catheter is set in the middle of the float plate; urine is collected by the urine collection bag to drive the float plate to rise and fall. When the urine is full, the float plate fits against the upper end of the square cavity and the square plate in the middle of the float plate fits against the lower end of the catheter to seal the urine collection bucket and prevent urine from overflowing.

[0022] The beneficial effects of the present invention are:

[0023] The present invention discloses a urine collection device for neonatal care, comprising: protective pants, a mask, a catheter, a suction pump, and a urine collection bag; the mask is arranged at a position on the protective pants corresponding to the urination site of the human body to cover the urination site; an adhesive layer is arranged on the outer periphery of the upper end of the mask to adhere to the skin around the urination site, and the protective pants have a certain elasticity to ensure that the mask is stably covered around the urination site. The protective pants can also cushion the impact of the mask on the neonatal limb movement, thereby preventing the mask from falling off due to the movement of the neonatal limb and preventing the urine collection from failing.

[0024] In addition, an absorption layer is provided at the upper end of the mask body, and a hollow cavity is provided inside the mask body. Through the setting of the frustum-shaped cavity that is narrow at the top and wide at the bottom, when urine flows back, it needs to overcome the gradient resistance from wide to narrow inside the frustum-shaped cavity, thereby limiting the backflow of urine; and a plurality of anti-backslip grooves are provided inside the hollow cavity, which disperse the backflow urine, extend the urine flow path, and reduce the potential energy of urine backflow, and the intervertebral space of the anti-backslip grooves faces the upper end of the mask body, and the 1 / 4 ring faces the lower end of the mask body. When urine flows back, it will fall into the concave space between the 1 / 4 ring and the wall of the frustum-shaped cavity. The concave space can greatly slowly release the potential energy of urine backflow, thereby avoiding the backflow of urine inside the mask body, thereby solving the problems in the prior art of urine splashing and urine backflowing to the periphery of the newborn's skin, which easily cause skin allergies and inflammation.

[0025] An absorption layer is provided on the upper end of the mask body to absorb urine that splashes and flows back onto the skin at the urination site, further preventing urine from causing allergic inflammation of the skin around the urination site, and preventing urine from soaking the adhesive layer and affecting the stability of the connection between the adhesive layer and the skin;

[0026] A urine collection bag is set up, and a negative pressure is achieved inside the urine collection bag through a suction pump to collect the urine in the cover into the urine collection belt. The urine collection bag is self-sealed through the interaction between the float plate and the urine to prevent urine overflow. The overflowing urine is collected by setting a protective bag to prevent urine from overflowing or entering the suction pump. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to solve the problems existing in the existing urine collection device for neonatal care, the present invention discloses a urine collection device for neonatal care, comprising: protective pants 1, a cover body 2, a catheter 4, a suction pump 5, and a urine collection bag 6;

[0038] The protective pants 1 are provided with a cover body 2 to cover the urination area of ​​the human body; a conduit 4 is provided at the lower end of the cover body 2 to connect to the urine collection bag 6 to realize the transportation and collection of urine; a branch pipe 401 is provided at the lower part of the conduit 4 to connect to the suction pump 5;

[0039] The cover body 2 is cylindrical, with a hollow cavity formed inside the cover body 2. The lower end of the cover body 2 is movably connected to the head end of the catheter 4. The upper end of the cover body 2 is provided with an annular groove for installing the absorption layer, and an adhesive layer 203 is provided on the wall of the cover body 2 outside the annular groove.

[0040] The upper portion of the hollow cavity is a cone-shaped cavity 2001 that is narrow at the top and wide at the bottom, and the lower portion is a funnel-shaped cavity that is wide at the top and narrow at the bottom. A plurality of anti-slip grooves 201 are arranged in an array on the walls of the cone-shaped cavity 2001 and the funnel-shaped cavity. One-way air valves 3 are symmetrically arranged on the walls of both sides of the cone-shaped cavity 2001.

[0041] The anti-slip pattern 201 has a semi-cone 2011 at its upper end and a quarter-circle ring 2012 at its lower end. The semi-cone 2011 has its apex facing the upper end of the cover 2, while the quarter-circle ring 2012 faces the lower end of the cover 2.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] A urine collection device for neonatal care with patent number CN202110599392.8 discloses that "a catheter 4 is embedded in the top of the urine bag, a connecting bag is nested in the top of the catheter 4, a foam adhesive sticker with a middle opening is embedded in the back of the connecting bag, a sealing mechanism is fixedly connected to the top of the urine bag, a first air bag is embedded in the sealing mechanism, a push plate is slidingly provided inside the sealing mechanism, a sealing block is fixedly connected to the push plate near one end of the catheter 4, a locking mechanism is nested on the outer surface of the bottom of the catheter 4, and an expansion surface is embedded in the inner wall of the connection between the catheter 4 and the locking mechanism. This type of urine collection device for neonatal care is provided with a sealing mechanism. By setting up the sealing mechanism, the urine inside the urine bag gradually discharges the air while also using the air pressure difference to drive the sealing blocks closer to each other, thereby realizing automatic detection and sealing of the urine collection amount inside the urine bag and preventing urine overflow."

[0044] However, in actual production and use, the following problems exist:

[0045] 1) Lack of powered suction device and no anti-reflux system, resulting in poor urine flow, causing:

[0046] ① Urine is severely retained inside the catheter 4, and the urine collection bag 6 collects little urine;

[0047] ② It is very easy to cause urine splashing and backflow, causing allergic inflammation of the skin around the urination site of the newborn;

[0048] ③Cause urine to soak into the foam glue, resulting in poor adhesion of the foam glue, and the connecting bag is easy to fall off, resulting in failure of urine collection;

[0049] 2) The impact of neonatal movement was not taken into consideration. A separate connecting bag was used to cover the urination area without any other protection. The neonatal's limb movement, such as kicking or turning over to the prone position, would bring strong external pressure to the connecting bag, tearing the foam adhesive, not only damaging the neonatal skin, but also causing the urine collection to fail.

[0050] Example 1

[0051] In response to the above problem 1), the present invention has taken multiple considerations and comprehensively combined the three improvement directions of dynamic suction, anti-backflow and skin wiping adsorption.

[0052] like Figure 2 As shown, in the present invention, a cover body 2, a catheter 4, a suction pump 5 and a urine collection bag 6 are provided;

[0053] The cover 2 covers the periphery of the newborn's urination site to collect urine; the lower end of the cover 2 is rotatably connected to the upper end of the catheter 4; a urine collection bag 6 is provided at the lower end of the catheter 4; the cover 2, the catheter 4 and the urine collection bag 6 complete the urine transport channel;

[0054] In this embodiment, a branch pipe 401 is vertically provided at the lower end of the conduit 4, and a wave pipe 402 is provided on the branch pipe 401 to connect to the suction pump 5. The suction pump 5 sucks and discharges air, maintaining a negative pressure state inside the urine collection bag 6 and the conduit 4, ensuring that after urine is collected inside the cover 2, the urine automatically moves toward the low-pressure direction, thereby realizing dynamic suction of urine;

[0055] In addition, during the power suction process, in order to avoid a complete seal, a negative pressure is formed inside the mask body 2, causing the mask body 2 to act like a suction cup and exert a large suction pressure on the skin around the newborn, resulting in skin damage to the newborn. A one-way air valve 3 is symmetrically provided on the wall of the mask body 2 extending out of the protective pants 1 to ensure that the pressure inside the mask body 2 is normal.

[0056] In this embodiment, a hollow cavity is provided inside the housing 2; the upper portion of the hollow cavity is a frustum-shaped cavity 2001 that is narrow at the top and wide at the bottom, and the lower portion is a funnel-shaped cavity that is wide at the top and narrow at the bottom; a plurality of anti-slip grooves 201 are arranged in an array on the walls of the frustum-shaped cavity 2001 and the funnel-shaped cavity; one-way air valves 3 are symmetrically provided on the walls of the frustum-shaped cavity 2001 on both sides; due to the arrangement of the frustum-shaped cavity 2001 that is narrow at the top and wide at the bottom, urine needs to overcome the gradient resistance from wide to narrow inside the frustum-shaped cavity 2001 when it flows back, thereby limiting the backflow of urine;

[0057] An anti-backslip pattern 201 is provided, wherein the upper end of the anti-backslip pattern 201 is a semi-cone 2011, and the lower end is a 1 / 4 ring 2012; the vertebral tip of the semi-cone 2011 faces the upper end of the cover body 2; the 1 / 4 ring 2012 faces the lower end of the cover body 2; the anti-backslip pattern 201 disperses the refluxed urine, extends the urine flow path, and reduces the urine reflux potential energy; and the intervertebral space of the anti-backslip pattern 201 faces the upper end of the cover body 2, and the 1 / 4 ring 2012 faces the lower end of the cover body 2. When urine refluxes, it will fall into the concave space between the 1 / 4 ring 2012 and the wall of the frustum-shaped cavity 2001. The concave space can greatly slowly release the urine reflux potential energy, thereby preventing urine reflux inside the cover body 2;

[0058] The cone-shaped cavity 2001 with a narrow top and wide bottom inside the cover body 2 and the anti-backflow pattern 201 work together to achieve urine backflow control and avoid urine backflow;

[0059] In this embodiment, an annular groove is provided at the upper end of the mask body 2 to install an absorption layer; the absorption layer includes but is not limited to a fine sponge layer, an absorbent cotton layer, etc.; the absorption layer absorbs a portion of urine that flows back or splashes onto the skin around the urination site;

[0060] To sum up, in this embodiment, the suction pump 5 is used to realize the dynamic suction collection of urine collected inside the cover body 2, and the anti-backflow control of urine is realized by the cone-shaped cavity 2001 which is narrow at the top and wide at the bottom inside the cover body 2 in combination with the anti-backflow slip pattern 201, and finally the absorption layer is combined to absorb the urine on the skin surface; the three improvement directions of dynamic suction, anti-backflow and skin wiping adsorption are comprehensively combined to specifically and effectively solve the problems of serious urine retention in the catheter 4, small urine collection volume of the urine collecting bag 6, easy urine splashing and backflow, resulting in allergic inflammation of the peripheral skin of the newborn urination site due to the influence of urine, and soaking of the foam glue by the backflow urine, resulting in poor adhesion of the foam glue, and easy falling off of the connecting bag, resulting in failure of urine collection.

[0061] Example 2

[0062] like Figure 1 As shown, in order to solve the problem 2), in the present invention, protective pants 1 and a cover body 2 are provided; Figure 2 As shown, the protective pants 1 are provided with a cover body 2 at the position corresponding to the urination position of the newborn; an adhesive layer 203 is provided on the outer peripheral wall of the upper end of the cover body 2;

[0063] In this embodiment, the protective pants 1 are in the shape of shorts and are made of a soft, skin-friendly and elastic material. The protective pants 1 protect the skin around the neonate's buttocks and urination area, and the elastic protective pants 1 compress the mask body 2 to enhance the stability of the mask body 2.

[0064] In this embodiment, the adhesive layer 203 includes but is not limited to: a silicone gel adhesive layer 203 or foam adhesive.

[0065] Example 3

[0066] In the present invention, the middle portion of the upper end of the urine collection bag 6 is integrally connected to the lower end of the catheter 4; the urine collection bag 6 is made of a hard transparent material layer, a capacity scale is set on the front wall of the urine collection bag 6, and a hook 601 is symmetrically set on the upper portion of the rear end of the urine collection bag 6 to be movably connected to the bed;

[0067] In this embodiment, the interior of the urine collecting bag 6 is a square cavity 602 of a fixed volume, and a floating plate 603 is movably provided inside the urine collecting bag 6;

[0068] The middle part of the floating plate 603 is provided with a square plate with a width equal to the width of the square cavity 602 and a length greater than 3 times the inner diameter of the catheter 4; the urine is collected by the urine collecting bag 6 to drive the floating plate 603 to rise and fall. When the urine is full, the floating plate 603 fits against the upper end of the square cavity 602; the square plate in the middle of the floating plate 603 fits against the lower end of the catheter 4 to seal the urine collecting bucket and prevent urine from overflowing.

[0069] In summary, the present invention discloses a urine collection device for neonatal care, comprising: protective pants 1, a cover 2, a catheter 4, a suction pump 5, and a urine collection bag 6; the protective pants 1 are provided with the cover 2 at a position corresponding to the urination site of the human body to cover the urination site of the human body; an adhesive layer 203 is provided on the outer periphery of the upper end of the cover 2 to adhere to the skin around the urination site, and the protective pants 1 have a certain elasticity to ensure that the cover 2 is stably covered around the urination site. In addition, the protective pants 1 can cushion the impact of the cover 2 on the urination site when the newborn's limbs move, thereby preventing the cover 2 from falling off due to the newborn's movement and thus preventing the urine collection from failing.

[0070] In addition, an absorption layer is provided at the upper end of the cover body 2, and a hollow cavity is provided inside the cover body 2. By setting the frustum-shaped cavity 2001 which is narrow at the top and wide at the bottom, when urine flows back, it needs to overcome the gradient resistance from wide to narrow inside the frustum-shaped cavity 2001, thereby limiting the backflow of urine; and a plurality of anti-back slip grooves 201 are provided inside the hollow cavity, which disperse the backflow urine by the anti-back slip grooves 201, extend the urine flow path, and reduce the potential energy of urine backflow, and the intervertebral space of the anti-back slip grooves 201 faces the upper end of the cover body 2, and the 1 / 4 circular ring 2012 faces the lower end of the cover body 2. When urine flows back, it will fall into the concave space between the 1 / 4 circular ring 2012 and the wall of the frustum-shaped cavity 2001. The concave space can greatly slowly release the potential energy of urine backflow, thereby preventing urine backflow inside the cover body 2, thereby solving the problems in the prior art of urine splashing and urine backflowing to the periphery of the skin of the newborn, which easily cause skin allergies and inflammation.

[0071] In addition, an absorption layer is provided on the upper end of the mask body 2 to absorb urine splashing and flowing back onto the skin at the urination site, thereby further preventing urine from causing allergic inflammation of the skin around the urination site and preventing urine from soaking the adhesive layer 203 and affecting the stability of the connection between the adhesive layer 203 and the skin.

[0072] A urine collecting bag 6 is provided, and negative pressure is achieved inside the urine collecting bag 6 by means of a suction pump 5, so that urine in the cover body 2 is collected into the urine collecting belt. The interaction between the float plate 603 and the urine enables the urine collecting bag 6 to be self-sealed, thereby preventing urine from overflowing. In addition, the overflowing urine is collected by means of a protective bag 7, thereby preventing urine from overflowing or entering the suction pump 5.
