Description

Technical Field

[0001] This utility model relates to the field of negative pressure urine collection bag technology, and in particular to a non-invasive negative pressure urine collection bag for women. Background Technology

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] CN217162428U describes a non-invasive negative pressure urine collection bag for women. It includes a perineal adhesive cover, a urination port, and an absorbent cotton layer. The perineal adhesive cover facilitates urine collection during urination. An infusion silicone tube, connector, and negative pressure bulb allow for flexible addition of the negative pressure bulb as needed. Manual pressing of the negative pressure bulb adjusts the internal and external pressure difference, enabling negative pressure drainage during bulb reset. A gas conversion valve separates the gas and liquid, ultimately collecting residual urine and keeping the perineal area dry. The negative pressure bulb is detachable.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] The pressing mechanism is located between the perineal adhesive mechanism and the drainage mechanism, which means that urine needs to flow through the negative pressure balloon before entering the drainage collection bag. However, the comparative document does not state that the device is disposable and emphasizes that the negative pressure balloon is detachable. It is reasonable to assume that the negative pressure balloon can be reused. However, the premise of repeated use is that urine residue inside the negative pressure balloon needs to be cleaned regularly. The openings at both ends of the negative pressure balloon are small and the internal space is large, making cleaning difficult and increasing labor intensity.

[0006] Meanwhile, the comparative document states that the negative pressure bulb is manually pressed, allowing for negative pressure drainage of the fluid during its repositioning process. This suggests that the solution utilizes the negative pressure generated during the repositioning of the bulb to drain urine collected by the perineal adhesive mechanism. The gas released during bulb pressing enters the drainage bag or the perineal adhesive mechanism. If the perineal adhesive mechanism is closed and sealed, and the drainage bag's output is shut, the gas cannot escape. Increased pressure may cause the perineal adhesive mechanism to become loose. Even if the perineal adhesive mechanism is not closed or the drainage bag's output is open, while the gas can be expelled from the bulb, the perineal adhesive mechanism must be closed or the drainage bag's output shut before the bulb is released and repositioned. This requires maintaining the bulb's pressure while using the other hand for other operations, making the process cumbersome and unsuitable for individual patient use. Utility Model Content

[0007] The purpose of this invention is to provide a non-invasive negative pressure urine collection bag for women, which has the advantages of creating negative pressure inside the collection bag to draw in urine, preventing urine from flowing into the negative pressure ball mechanism, and setting a one-way valve to prevent airflow from the negative pressure ball mechanism from flowing back into the collection bag. It solves the technical problem that the negative pressure ball mechanism requires cleaning residual urine during repeated use, and that it requires keeping the negative pressure ball pressed while using another hand to fasten the vaginal adhesive mechanism or close the output end of the collection bag, which is cumbersome to operate.

[0008] This utility model provides a non-invasive negative pressure urine collection bag for women, comprising:

[0009] The drainage bag has a first silicone tube fixedly connected to one end of its input end, and a perineal fastening cover fixedly connected to the other end of the first silicone tube.

[0015] A cone-shaped silicone cover, with its opening edge glued and fixed to the outside of the user's perineum;

[0016] The smaller end of the conical silicone cover is fixedly connected to the first silicone tube;

[0017] The conical silicone cover has an absorbent cotton layer fixedly fitted inside its cavity.

[0018] As a further optimization, in order to block and absorb urine and reduce urine splashing, the urine is allowed to enter the first silicone tube along the absorbent cotton layer structure, the absorbent cotton layer structure including:

[0019] The absorbent cotton has a mesh cover wrapped around its outer wall.

[0020] The outer wall of the absorbent cotton layer is fixedly connected to the inner wall of the conical silicone cover via a connecting rope.

[0021] As a further optimization, in order to collect urine by being adhered to the outside of the user's perineum via an adhesive layer, the cone-shaped silicone cover includes:

[0022] The main body of the cone-shaped silicone cover has an outer adhesive layer on the outer side of its upper edge;

[0023] The inner side of the upper edge of the conical silicone cover body is provided with an inner adhesive layer.

[0024] As a further optimization, in order to bind the perineal fastening cover to the user's torso and improve the connection strength of the perineal fastening cover, the left and right edges of the bottom surface of the conical silicone cover are fixedly equipped with first straps.

[0025] As a further optimization, in order to create negative pressure inside the drainage bag by pressing the negative pressure ball, one-way valves are installed on both sides of the negative pressure ball, so that the gas can flow in the expected direction and prevent backflow. The negative pressure ball pressing mechanism includes:

[0026] The negative pressure ball has a second silicone tube fixedly connected to its input end, and the other end of the second silicone tube is fixedly connected to the output end of the drainage collection bag.

[0027] The negative pressure ball has a fixed unidirectional output tube connected to the opposite side of its input end.

[0028] As a further optimization, in order to improve the wear resistance of the gripping area on the outer wall of the negative pressure ball and extend its service life, a wear-resistant rubber sleeve is fixedly fitted onto the middle of the outer wall of the negative pressure ball.

[0029] As a further optimization, to cooperate with the negative pressure ball mechanism to create negative pressure inside the urine bag, the negative pressure acts on the perineal fastening cover through the first silicone tube, collecting urine and introducing it into the drainage collection bag, which includes:

[0030] The urine bag has a flexible bag at the bottom and a rigid cylindrical shape at the top, and the two ends of the urine bag are fixedly connected.

[0031] The upper end of the urine bag is screwed with a top cover;

[0032] An output pipe and an input pipe are fixedly connected to the upper surface of the cover;

[0036] As a further optimization, in order to hang the urine bag on an external hook for use, a hanging ring is fixedly fitted to the upper outer wall of the urine bag.

[0037] As a further optimization, in order to secure the urine bag to the user's body for easy use, a second strap is fixedly fitted on both the left and right sides of the lower outer wall of the urine bag.

[0038] This utility model provides an improved non-invasive negative pressure urine collection bag for women, which has the following improvements and advantages compared with the prior art:

[0039] The drainage bag is directly connected to the perineal fastening cover via a first silicone tube. The perineal fastening cover is used to collect urine on the outside of the user's perineum. A negative pressure bulb mechanism is used to expel air from the drainage bag, creating negative pressure within the bag to draw in urine. Urine does not flow into the negative pressure bulb mechanism, eliminating the need for cleaning residual urine during repeated use. A one-way valve prevents airflow from the negative pressure bulb mechanism from flowing back into the drainage bag; the expelled air is directly discharged to the outside. This allows the patient to independently collect urine using only one hand. This avoids the need to expel air from the negative pressure bulb, which would otherwise require using the other hand to fasten the perineal fastening mechanism or close the drainage bag's output end while the negative pressure bulb is pressed, due to improper design.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] Please see Figure 1-5 This utility model provides a technical solution: a non-invasive negative pressure urine collection bag for women, comprising:

[0052] The drainage bag 2 has a first silicone tube 3 fixedly connected to one end of its input end, and the other end of the first silicone tube 3 is fixedly connected to the perineal fastening cover 1.

[0053] The perineal fastening cover 1 is fastened to the outside of the user's perineum;

[0054] The output end of the drainage bag 2 is fixedly connected to the negative pressure ball mechanism 4, and its output end is connected to the outside.

[0055] A one-way valve 7 is provided on the pipeline connecting the negative pressure ball mechanism 4 and the output end of the drainage bag 2;

[0056] The one-way valve 7 allows unidirectional flow from the output end of the drain bag 2 to the negative pressure ball mechanism 4.

[0057] Specifically in this embodiment, the drainage collection bag 2 is a bag-shaped container used to collect urine; the first silicone tube 3 is made of medical silicone; the perineal fastening cover 1 is made of medical silicone, with its upper edge pasted on the outside of the user's perineum to collect and temporarily store the excreted urine, allowing sufficient time for subsequent negative pressure drainage.

[0058] Furthermore, the drainage collection bag 2 is directly connected to the perineal fastening cover 1 through the first silicone tube 3. The perineal fastening cover 1 is fastened to the outside of the user's perineum to receive urine. The air inside the drainage collection bag 2 is discharged by pressing the negative pressure ball mechanism 4, and a negative pressure is formed in the drainage collection bag 2 to draw in urine. The urine will not flow into the negative pressure ball mechanism 4, so that the negative pressure ball mechanism 4 does not need to be cleaned of residual urine during repeated use.

[0059] More specifically, the one-way valve 7 prevents the airflow from the negative pressure ball mechanism 4 from entering the drainage collection bag 2 in the reverse direction, and the discharged gas is directly discharged into the outside, so that the patient can independently complete the negative pressure collection of urine with one hand. This avoids the need to discharge the gas generated by pressing the negative pressure ball due to improper design, which would require the patient to use the other hand to fasten the vaginal adhesive mechanism 1 or close the output end of the drainage collection bag 2 while keeping the negative pressure ball pressed. This allows the patient to complete the operation independently with one hand.

[0060] It is understandable that the perineal fastening cover 1, drainage collection bag 2, and first silicone tube 3 are all disposable items. After the drainage collection bag 2 is full, they are stored together. The disassembled negative pressure ball mechanism 4 can be reused.

[0061] Medical silicone devices are commonly used as disposable items in the medical device field, such as disposable silicone drainage tubes, disposable gastric tubes, and disposable silicone urinary catheters.

[0062] In some embodiments, the perineal fastening cover 1 includes:

[0063] A cone-shaped silicone cover 11, the opening edge of which is glued and fixed to the outside of the user's perineum;

[0064] The smaller end of the conical silicone cover 11 is fixedly connected to the first silicone tube 3;

[0065] The inner cavity of the conical silicone cover 11 is fixedly equipped with an absorbent cotton layer structure.

[0066] Specifically, in this embodiment, the conical silicone cover 11 is made of conical silicone material, and the material is medical silicone.

[0067] Furthermore, the conical silicone cover 11 is fixed to the outside of the user's perineum, and the collected urine is introduced into the drainage collection bag 2 through the first silicone tube 3.

[0068] In some embodiments, the absorbent cotton layer structure includes;

[0069] The absorbent cotton 13 has a mesh cover 12 wrapped around its outer wall;

[0070] The outer wall of the absorbent cotton layer structure is fixedly connected to the inner wall of the conical silicone cover 11 by a connecting rope.

[0071] Specifically, in this embodiment, the absorbent cotton 13 is a prior art material, made of microfiber, which can quickly absorb liquid several times its own weight.

[0072] Furthermore, the mesh cover is made of plastic and is used to support and place the absorbent cotton 13. The absorbent cotton 13 can be set in multiple layers to ensure the absorbent capacity.

[0073] More specifically, the absorbent cotton 13 blocks and absorbs urine, reducing urine splashing, and allows urine to enter the first silicone tube 3 along the absorbent cotton layer structure.

[0074] In some embodiments, the conical silicone cover 11 includes:

[0075] A conical silicone cover body 113 has an outer adhesive layer 111 on the outer side of its upper edge;

[0076] An inner adhesive layer 112 is provided on the inner side of the upper edge of the cone-shaped silicone cover body 113.

[0077] Specifically, in this embodiment, the conical silicone cover body 113 is a conical cover made of medical silicone material, and the lower end of it is connected to the first silicone tube 3;

[0078] Furthermore, an outer adhesive layer 111 is provided on the outer ring of the upper edge of the conical silicone cover body 113, and an inner adhesive layer 112 is provided on the inner ring of the upper edge of the conical silicone cover body 113. The double adhesive layer ensures the bonding strength.

[0079] In some embodiments, the left and right edges of the bottom surface of the conical silicone cover 11 are fixedly fitted with first straps 6.

[0080] Specifically in this embodiment, the first strap 6 is a cloth strap. The first straps 6 on both sides bind the perineal fastening cover to the user's torso, improve the connection strength of the perineal fastening cover 1, reduce the force on the upper edge of the perineal fastening cover 1, and reduce the risk of separation at the adhesive point.

[0081] In some embodiments, the negative pressure ball pressing mechanism 4 includes:

[0082] The negative pressure ball 41 has one end of the second silicone tube 43 fixedly connected to its input end, and the other end of the second silicone tube 43 is fixedly connected to the output end of the drainage receiving bag 2.

[0083] A unidirectional output tube 42 is fixedly connected to the opposite side of the input end of the negative pressure ball 41.

[0084] Specifically, in this embodiment, the negative pressure ball 41 is existing technology, usually a ball with connection ports at both ends, and is made of medical silicone; the one-way output tube 42 has a built-in one-way valve, allowing one-way flow from the negative pressure ball 41 to the outside.

[0085] Furthermore, after pressing the negative pressure ball 41, the one-way output pipe 42 discharges the gas inside the negative pressure ball 41 to the outside. Due to the setting of the one-way valve 7, this part of the gas is prevented from entering the drainage collection bag 2.

[0086] After the negative pressure ball 41 is released, it automatically resets. Negative pressure is generated inside the negative pressure ball 41, which draws in gas from the drainage bag 2 through the second silicone tube 43. The gas is then discharged to the outside through the one-way output tube 42, generating negative pressure inside the drainage bag 2.

[0087] More specifically, when using the negative pressure ball 41, control the pressing frequency. After pressing once, when the flow rate of urine aspirated by negative pressure slows down, press the negative pressure ball 41 again to maintain the continuity of urine aspirated by negative pressure.

[0088] In some embodiments, a wear-resistant rubber sleeve 5 is fixedly sleeved on the middle of the outer wall of the negative pressure ball 41. The wear-resistant rubber sleeve 5 is made of wear-resistant rubber material, which improves the wear resistance of the gripping part of the outer wall of the negative pressure ball 41 and extends the service life of the negative pressure ball 41.

[0089] In some embodiments, the drainage collection bag 2 includes:

[0090] The urine bag 21 has a flexible bag body at the lower end and a rigid cylindrical shape at the upper end, and the upper and lower ends of the urine bag 21 are fixedly connected.

[0091] The upper end of the urine bag 21 is screwed with a cover 22;

[0092] The upper surface of the cover 22 is fixedly connected to the output tube 24 and the input tube 23;

[0093] The input pipe of the press-down negative pressure ball mechanism 4 is connected to the outside of the output pipe 24;

[0094] The output end of the first silicone tube 3 is connected to the outside of the input tube 23;

[0095] The upper surface of the cover 22 is fixedly connected to the drain pipe 25, and a plug cap is fastened to its upper end.

[0096] Specifically, in this embodiment, the urine bag 21 is made of plastic, with the upper end being rigid plastic and the lower end being flexible plastic, and the upper cover 22 being rigid plastic.

[0097] Furthermore, the outer walls of both the output tube 24 and the input tube 23 are provided with multiple annular protrusions for better connection of the first silicone tube 3 and the second silicone tube 43.

[0098] More specifically, after the cap at the top of the drain tube 25 is opened, urine can be poured out of the urine bag 21 through the drain tube 25. When there is no spare urine bag 21 to replace and there is an urgent need to urinate, it can be reused in this way. After obtaining a urine bag 21, it should be replaced in time.

[0099] In some embodiments, a hanging ring 8 is fixedly fitted to the upper outer wall of the urine bag 21, which facilitates hanging the urine bag on an external hook for use when the patient is in bed.

[0100] In some embodiments, the lower outer wall of the urine bag 21 is fixedly equipped with second straps 9 on both the left and right sides. When walking is required, the urine bag is fixed to the user's body by the second straps 9 on both sides for easy carrying and use. The second straps 9 are specifically cloth straps.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
