Description

Technical Field

[0001] This invention relates to a urethral examination fixation device, and more particularly to a urine collection and tubing fixation device specifically designed for pediatric urodynamic examinations. Background Technology

[0002] Urodynamic testing is an important examination in urology, designed to assess the functional status of the bladder and urethra by measuring parameters such as pressure and flow rate during urine storage and voiding. This examination helps doctors understand the physiological mechanisms of the urinary tract and identify the root causes of symptoms such as difficulty urinating and urinary incontinence. Except for uroflowmetry, all urodynamic tests are invasive, requiring the insertion of pressure-measuring catheters through the urethra, anus, bladder, and rectum. The urodynamic analyzer uses bladder and rectal pressure-measuring catheters to measure pressure in the bladder and rectum, respectively, thereby clarifying the physiological processes of urine storage and voiding and the causes of functional disorders.

[0003] Currently, there is no specific fixation device for urodynamic testing in clinical practice. Medical tape is mainly used to fix bladder and rectal manometry tubes to the patient's skin. However, medical tape not only fails to provide secure fixation but also causes discomfort to the patient, posing potential risks to clinical work. Furthermore, children's skin is more sensitive and prone to allergies to tape, and their movements are often uncontrollable, causing many difficulties in conducting urodynamic testing.

[0004] In addition, when children undergo urodynamic testing, it is necessary to observe the urodynamic test results during urination. During this process, because children are active, the position of their penis can easily change. If the child urinates, the urine can easily spill out from the surface of the catheter. Summary of the Invention

[0005] The present invention aims to provide a urine collection and tubing fixing device for pediatric urodynamic examinations, to solve the problems of how to fix the urinary catheter and how to store spilled urine to prevent urine from leaking to the outside.

[0006] To achieve the above objectives, the specific plan is as follows:

[0007] A urine collection and tubing fixation device specifically designed for pediatric urodynamic testing, comprising:

[0008] The urinary catheter fixing part has several first fixing bands on its outer wall surface, and a first fixing sticker is provided at the end of the first fixing band away from the urinary catheter fixing part; a through hole is provided in the middle of the urinary catheter fixing part.

[0009] The urine storage cover is located at the bottom of the urinary catheter fixation part and adopts a multi-layer structure design, including an inner absorbent layer and a fixation layer on the surface of the absorbent layer; the absorbent layer is made of absorbent dressing and the fixation layer is made of waterproof material.

[0010] A fixing ring is located at the bottom of the urine storage cover, and several second fixing straps are provided on it. The ends of the second fixing straps are provided with second fixing stickers. The second fixing straps include a rough-surface fixing strap and a hook-surface fixing strap.

[0011] Furthermore, both the first and second fixing patches adopt a multi-layer structure design, including a peelable surface layer, an adhesive layer, and a first soft layer; the peelable surface layer and the first soft layer are respectively disposed on both sides of the adhesive layer; the adhesive layer is a hypoallergenic medical tape.

[0012] Furthermore, an adhesive layer is provided between the absorbent layer and the fixing layer.

[0013] Furthermore, the hook-and-loop fastener has a second soft layer on the side that fits against the skin.

[0014] Furthermore, the upper and lower ends of the urine storage cover, the lower end of the urine catheter fixing part, and the upper end of the fixing ring are all provided with a first magnetic suction component, and the urine storage cover, urine catheter fixing part, and fixing ring are detachably connected together through the first magnetic suction component.

[0015] The urine storage cover includes a left cover and a right cover, and the contact surfaces of the left cover and the right cover are provided with a second magnetic assemblies, which allow the two to be detachably joined together.

[0016] Furthermore, the upper and lower ends of the urine storage cover, the lower end of the urine catheter fixing part, and the upper end of the fixing ring are all provided with connecting grooves or connectors, and the first magnetic suction assembly is assembled on the connecting grooves and connectors.

[0017] Furthermore, a clamping mechanism is provided inside the catheter fixing part, and a knob is provided on the surface of the catheter fixing part.

[0018] Furthermore, the clamping mechanism includes a pawl, a wire disc, a gear, and a knob connected to the gear; the urinary catheter fixing part is provided with several grooves, several pawls are arranged in the grooves, and one side of the pawl is provided with a pawl tooth, and one side of the wire disc is provided with a spiral tooth. The pawls are engaged with the spiral tooth to realize the assembly of the pawls and the wire disc; the other side of the wire disc is provided with a tooth pattern, and the gear is engaged with the other side of the wire disc.

[0019] Furthermore, the first and second fixing bands are elastic bands; the absorbent dressing is a highly absorbent fiber dressing, alginate dressing, or low-sensitivity hydrocolloid dressing; and the waterproof layer is made of lightweight plastic.

[0020] Furthermore, the urine storage cover is shovel-shaped or bell-shaped.

[0021] In summary, the present invention has the following advantages over the prior art:

[0022] (1) This device adopts a combined fixation structure of tubing clamping and upper and lower double straps, which has a fixation effect far superior to traditional medical tape. The urinary catheter fixation part integrates a clamping mechanism consisting of claws, wire discs, gears and knobs. Rotating the knob can simultaneously retract the claws, and the clamping range can be flexibly adjusted according to the outer diameter of the tubing. It can firmly clamp different specifications of pediatric pressure measuring tubes and urinary catheters, effectively preventing the tubing from loosening, bending, or slipping. At the same time, the urinary catheter fixation part is equipped with a first elastic fixation band and a fixation ring is equipped with a second elastic fixation band. The two sets of fixation structures form upper and lower double limits, which can fully adapt to the characteristics of children's active nature and large range of limb movements, and avoid tubing traction and displacement throughout the process. After the tubing position is stable, the pressure, flow and other parameters collected by the urodynamics detector are not affected by external interference, ensuring the accuracy of the test results from the root.

[0023] (2) The urine storage cover adopts a fully enclosed split structure, which can fit tightly to the genital area of ​​the child. Combined with a multi-layer composite anti-seepage structure, it can achieve efficient urine collection and leakage prevention. The inner absorbent layer is made of highly absorbent fiber dressing, alginate dressing or low-sensitivity hydrocolloid dressing, which has a high water absorption ratio and strong water-locking ability. It can quickly absorb urine overflowing around the tubing and prevent backflow. The middle adhesive layer allows the absorbent layer to be disassembled and assembled. The outer fixed layer made of lightweight waterproof material forms a complete waterproof barrier to prevent urine from seeping outward. At the same time, the urine catheter fixing part, urine storage cover, and fixing ring are all sealed and connected by magnetic components with connecting grooves and connectors. The splicing end faces fit tightly, preventing urine from leaking from the assembly gaps, effectively avoiding urine contamination of bedding and hospital gowns, and maintaining a clean treatment environment.

[0024] (3) Taking into full account the physiological characteristics of children's sensitive skin and weak friction resistance, all parts in contact with the skin are optimized for protection. The first and second fixing tapes adopt a three-layer composite structure of a peelable surface layer, a low-sensitivity adhesive layer, and a soft padding layer. The adhesive layer is made of medical low-sensitivity tape, which has antibacterial and anti-allergic properties. The soft padding layer can buffer the pressure caused by the tape, greatly reducing the risk of skin redness, itching, and allergies. The second fixing tape has a second soft layer on the inside of the hook side, which can be made of medical soft fibers, PU soft foam, medical silicone, etc., to eliminate the scratching, pressure, and friction irritation of the hard fabric of the Velcro on the skin. All parts in contact with the human body are made of medical compliant low-sensitivity materials, and will not cause discomfort even after wearing for a long time, effectively improving the cooperation of children during examinations.

[0025] (4) The device adopts a modular magnetic design, which can be assembled and disassembled by hand without the need for additional tools. The urinary catheter fixation part, urine storage cover and fixation ring are quickly connected and disassembled by the first magnetic component. The urine storage cover is divided into two independent parts, left and right, which are opened and closed by the second magnetic component. Medical staff can first complete the insertion and fixation of the examination tubing, then fasten the urine storage cover from both sides, and finally assemble the fixation ring. There is no need to put the whole device into the tubing in advance. The operation process is simple and convenient, which greatly shortens the preoperative preparation time. It is especially suitable for young children with poor cooperation and reduces the difficulty of clinical operation.

[0026] (5) This invention distinguishes between disposable consumables and reusable main structures, resulting in significant economic advantages. The absorbent layer inside the urine storage cover is an independent and detachable component. After a single use and wetting, only the absorbent dressing needs to be replaced. The core components, such as the catheter fixation part, urine storage cover shell, fixing ring, magnetic suction assembly, and clamping mechanism, can be reused repeatedly after routine medical disinfection. Compared to the traditional method of using disposable consumables throughout the entire process or frequently changing medical tape, this device significantly reduces the consumption of medical consumables, and long-term use can significantly reduce departmental operating costs.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] like Figures 1 to 8As shown, this invention provides a urine collection and tubing fixation device specifically designed for pediatric urodynamic examinations. It mainly consists of a catheter fixation part 1, a urine storage cover 2, and a fixing ring 3 connected sequentially from top to bottom. These components work together to achieve catheter fixation, leak-proof urine collection, and hypoallergenic skin protection, thus meeting the clinical needs of pediatric urodynamic examinations. The functions and connections of each component are as follows:

[0043] The urinary catheter fixation part 1 is the core component for tubing positioning. Several first fixing bands 11 are provided on the outer wall of the urinary catheter fixation part 1. Each first fixing band 11 is made of medical elastic material, and a first fixing sticker 12 is fixed to its end for adhesion to the skin of the thigh (the adhesion position can be adjusted according to specific needs), thus achieving stable fixation of the urinary catheter fixation part 1. A through hole 13 is opened in the center of the urinary catheter fixation part 1. The hole diameter matches the outer diameter of the pediatric urethral pressure measuring tube and urinary catheter, allowing the examination tubing to pass through and be centered and limited, completely preventing tubing deviation, bending, or traction on the penis.

[0044] The urine storage cover 2 is connected to the bottom of the urinary catheter fixation part 1, fully covering the penis (glans area). It employs a multi-layered composite structure to absorb urine produced during urodynamic testing in children. The innermost layer (the layer that fits against the genitals) of the urine storage cover 2 is an absorbent layer 21, made of absorbent dressing, used to absorb urine overflowing from the urinary catheter surface, preventing urine from staining hospital gowns or bed sheets. The outermost layer is a fixation layer 22, which prevents urine from seeping from the absorbent layer 21 to the outside.

[0045] The fixing ring 3 is located at the bottom of the urine storage cover 2, and has several second fixing bands 31 (medical elastic bands) on it. The ends of the second fixing bands 31 are provided with second fixing stickers 32. The second fixing bands 31 are divided into rough-surface fixing bands 311 and hook-surface fixing bands 312 according to the rough and hook surfaces provided on them. In use, the hook-surface fixing bands 312 are used to be placed against the skin (root of the penis), and the rough-surface fixing bands 311 are cross-attached to the hook-surface fixing bands 312. Then, the second fixing 32 of the rough-surface fixing bands 311 and the hook-surface fixing bands 312 are attached to the skin at the root of the genitals and perineum (the attachment position is adjusted according to specific needs), thereby fixing the fixing ring 3.

[0046] The actual steps of using this device are as follows: The patient lies on the hospital bed with his genitals hanging down naturally. The medical staff inserts the urinary catheter into the patient's genitals through the through hole 13. During this process, the urinary catheter is fixed in position by the urinary catheter fixing part 1. The urine storage cover 2 is fixed by the fixing ring 3, the urinary catheter fixing part 1 and the patient's genitals (glans position). The fixing ring 3 can further fix the position of the urinary catheter fixing part 1, making it more stable.

[0047] When it is necessary to observe the patient's urodynamic testing during urination, if the urine overflows from the catheter, it will be absorbed by the absorbent layer 21 to avoid contaminating the bed sheets or hospital gowns.

[0048] As a preferred option, to avoid allergic reactions at the application site on children's skin, both the first adhesive patch 12 and the second adhesive patch 32 include a three-layer design. The middle layer of the adhesive patch is an antibacterial and hypoallergenic adhesive layer 101, with a peelable surface layer 100 and a first soft layer 102 on either side. In use, removing the peelable surface layer 100 exposes the antibacterial and hypoallergenic adhesive layer 101, which can be directly adhered to the skin. Because the antibacterial and hypoallergenic adhesive layer 101 has antibacterial and hypoallergenic properties, it can prevent allergic reactions in children.

[0049] As a preferred option, the adhesive layer 101 is a low-sensitivity medical tape.

[0050] As a preferred embodiment, an adhesive layer 23 is provided between the urine-absorbing layer 21 and the fixing layer 22 inside the urine storage cover 2. The adhesive layer 23 is used to bond the urine-absorbing layer 21, thereby realizing the detachable connection of the urine-absorbing layer 21 and allowing the urine storage cover 2 to be reused. In addition, in actual use, different sizes of urine-absorbing layers 21 can be selected according to the size of the patient's genitals and bonded to the adhesive layer 23, so that it can be customized to meet the needs of different patients.

[0051] As a preferred option, the hook-and-loop fastener 312 has a second soft layer 200 on the side that is in contact with the skin. The second soft layer 200 is made of hypoallergenic material to prevent allergies and other problems caused by children's sensitive skin.

[0052] The second soft layer 200 can be made of medical soft fiber, PU soft foam, or thin medical silicone.

[0053] Structure and Assembly: Full coverage is laminated on the inside of the hook and loop fastener, eliminating friction and irritation from the hard fabric. The texture is soft and will not irritate the skin or cause allergies during exercise.

[0054] Medical-grade soft fleece fiber layer: made of ultra-fine polyester soft fleece material, with a smooth surface and no hard edges, and an extremely low coefficient of friction. It is specially designed for the inside of the hook side of Velcro, completely avoiding scratches and skin irritation from the hook side fabric. It is highly soft and comfortable for children to wear and move around without discomfort.

[0055] Medical-grade polyurethane (PU) soft foam layer: High-elasticity closed-cell / open-cell soft foam with good resilience and a soft texture, providing cushioning and pressure relief to prevent prolonged pressure from a rigid substrate on the skin. The breathable foam also reduces sweating and is suitable for wraparound skin-contact areas such as support rings and straps.

[0056] Medical-grade silicone soft layer: Excellent biocompatibility, a top-tier hypoallergenic material, with a warm and soft touch, waterproof, easy to wipe clean, and reusable. Thin silicone pads can be directly laminated onto the substrate surface, odorless, non-allergenic, and suitable for contact areas worn for extended periods.

[0057] As a preferred embodiment, the upper and lower ends of the urine storage cover 2, the lower end of the urine catheter fixing part 1 (the end near the urine storage cover 2), and the upper end of the fixing ring 3 (the end near the urine storage cover 2) are all provided with a first magnetic attraction component 6, thereby realizing the detachable connection of the urine storage cover 2, the urine catheter fixing part 1, and the fixing ring 3; in addition, the urine storage cover 2 includes two parts, a left cover 24 and a right cover 25, and the contact surfaces of the left cover 24 and the right cover 25 are provided with a second magnetic attraction component 7, and the two are detachably connected together by the second magnetic attraction component 7.

[0058] Dividing the urine storage cover 2 into two independent parts, the left cover 24 and the right cover 25, allows medical staff to more accurately fit the device onto the patient's glans penis. In other words, in actual use, the urine storage cover 2 can be fixed after the urinary catheter fixing part 1 has fixed the urinary catheter, and finally the fixing ring 3 is used to reinforce the entire structure, making the device more stable.

[0059] As a preferred embodiment, in order to make the urine storage cover 2 fit more tightly with the fixing ring 3 and the urine tube fixing part 1 and prevent urine from leaking out from the gaps, the upper and lower ends of the urine storage cover 2, the lower end of the urine tube fixing part 1 (the end closer to the urine storage cover 2) and the upper end of the fixing ring 3 (the end closer to the urine storage cover 2) are provided with connecting grooves 8 or connecting parts 9, and the first magnetic suction assembly 6 is set through the connecting grooves 8 or connecting parts 9.

[0060] As a preferred embodiment, the first fixing band 11 and the second fixing band 31 are elastic bands; the absorbent dressing is a highly absorbent fiber dressing, an alginate dressing, or a low-sensitivity hydrocolloid dressing; and the waterproof layer is made of lightweight plastic.

[0061] Among them, highly absorbent fiber dressings and alginate dressings have the advantages of super absorbency (10-20 times their own weight), water retention, non-reverse seepage, and antibacterial properties; they are suitable for urinary catheter openings, around stomas, and eroded skin, reducing urine irritation. Hydrocolloid dressings (hypoallergenic) are suitable for small amounts of exudate / mild irritation, and have the advantages of protecting the skin and preventing allergies, making them suitable for application to areas easily soaked in urine.

[0062] As a preferred embodiment, in order to enable the urinary catheter fixing part 1 to fix urinary catheters of different diameters, the urinary catheter fixing part 1 is provided with a clamping mechanism 5, and the surface of the urinary catheter fixing part 1 is provided with a knob 4; in use, rotating the knob 4 can cause the clamping mechanism 5 to retract, thereby realizing the clamping operation of the urinary catheter, thereby achieving the purpose of fixing urinary catheters of different diameters.

[0063] As a preferred embodiment, the clamping mechanism 5 is a chuck, which mainly consists of a jaw 51, a wire disc 52, a gear 53, and a knob 4 connected to the gear. The catheter fixing part 1 has several grooves, and the jaw 51 is positioned within these grooves. One side of the jaw 51 within the catheter fixing part 1 has locking teeth, and one side of the wire disc 52 has spiral teeth. The jaw 51 engages with the spiral teeth to assemble with the wire disc 52. The other side of the wire disc 52 has teeth, and the gear 53 engages with the other side of the wire disc 52. In use, rotating the knob 4 causes the gear 53 to rotate the wire disc 52, allowing the jaw 51 to move horizontally on the spiral teeth, thus achieving the clamping operation of the catheter.

[0064] The specific usage method of this device is as follows:

[0065] S1: Assist the child to lie supine, relax naturally, and let the genitals hang down naturally; insert the urodynamic testing pressure measuring tube / catheter through the through hole 13 in the center of the urinary catheter fixation part 1 into the child's urethra and make preliminary adjustments to the position of the tube.

[0066] S2: Rotate the knob 4 on the outside of the urinary catheter fixing part 1 to drive the clamping mechanism 5 to retract the claws 51 and firmly clamp the tubing; then peel off the tearable surface layer 100 of the first fixing patch 12, stretch the first fixing band 11, and stick the first fixing patch 12 to the skin of the child's two thighs to complete the positioning of the urinary catheter fixing part 1.

[0067] S3: Separate the left cover 24 and right cover 25 of the urine storage cover 2, and cover the glans area of ​​the child from both sides with the two sets of covers, and fasten them together by relying on the second magnetic suction component 7; then align the upper end of the urine storage cover 2 with the lower end of the urinary catheter fixing part 1, and complete the docking by the first magnetic suction component 6.

[0068] S4: Magnetically connect the upper end of the fixing ring 3 to the lower end of the urine storage cover 2 (Note: Place the fixing ring 3 at the base of the penis before inserting the catheter); unfold the second fixing band 31, attach the hook-side fixing band 312 to the skin, cross-attach the rough-side fixing band 311, and finally peel off the isolation layer of the second fixing patch 32 and attach it to the base of the penis and the perineum to complete the overall double reinforcement of the device.

[0069] S5: The urodynamic examination is officially carried out. During the examination, the urine that overflows will be completely absorbed by the urine-absorbing layer 21. After the examination, peel off the fixing tape, untie the Velcro straps, disassemble each magnetic component and remove the device. Replace the wetted urine-absorbing layer 21 separately. The main body of the device can be reused after disinfection.

[0070] As a preferred option, such as Figure 9As shown, to accommodate pediatric patients of different genders, the urine storage cover 2 also includes a shovel shape. In other words, this application adapts to different usage scenarios by providing two different shapes:

[0071] Bell-shaped: a conventional shape with strong coverage, mainly suitable for routine urodynamic examinations in male children;

[0072] Shovel-shaped (see Figure 9): The outline is flatter and the coverage is wider, which can be adapted to different usage positions. At the same time, it can be extended to examination scenarios for women and children, making it more versatile.

[0073] Note: When the urine storage cover 2 is shovel-shaped, the dimensions of the fixing ring 3 at the bottom and the urine tube fixing part 1 at the top can be changed according to the actual dimensions of the urine storage cover 2, so they will not be described in detail.

[0074] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0075] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
