Description

Technical Field

[0001] This invention belongs to the field of urine collection bag technology, specifically a mother-and-child type urine collection bag. Background Technology

[0002] Urine collection bags are common instruments used in clinical nursing for collecting and measuring urine. They are usually connected to the patient via a catheter and secured to the bedside with a hanging strip. Most existing urine collection bags are single-bag structures, but there are also mother-daughter type bags that use a mother bag and a daughter bag. A mother-daughter type bag generally consists of a mother bag and a daughter bag. The upper end of the daughter bag is connected to the catheter, and the lower end of the daughter bag has an upper coupling seat. The upper end of the mother bag has a lower coupling seat, and the lower end of the mother bag has a discharge valve. The lower end of the daughter bag has a sealing valve. The upper and lower coupling seats are connected by insertion or snap-fit ​​methods to achieve communication and fixation between the daughter bag and the mother bag.

[0003] While mother-daughter urine collection bags can increase collection capacity and reduce the frequency of changes, they have more structural components. The mother and daughter bags together form the collection system, resulting in a relatively large overall weight. During use, the urine collection bag is hung by the bedside via a hanging strip. As urine is collected, the weight of the bag gradually increases, and the tension on the hanging area and the connection between the mother and daughter bags also increases. Compared to a simple single-bag urine collection bag, the mother-daughter bag is much heavier after urine accumulation. If the hanging is not secure, the hook slips, or the patient moves, the tension can easily be transmitted through the daughter bag, upper coupling seat, and lower coupling seat to the catheter, causing traction on the catheter. This can lead to patient discomfort or, in severe cases, catheter displacement or even damage to the urethra.

[0004] Existing mother-and-daughter type urine collection bags typically use upper and lower coupling seats that only serve a connecting and fixing function, with relatively simple connection structures. They usually rely on insertion, threads, or snaps to maintain the connection. This type of structure makes it difficult to control the tensile force at the connection point. When the tensile force is low, the connection can maintain a seal; however, when the tensile force exceeds a certain limit, if the connection cannot be disengaged in time, it will directly pull on the catheter. If the connection does disengage, it is often impossible to seal both the upper and lower coupling seats simultaneously, leading to residual urine leakage, contaminating bed sheets and the environment, and potentially increasing the risk of retrograde infection. Therefore, a mother-and-daughter type urine collection bag needs to be designed. Summary of the Invention

[0005] The purpose of this invention is to provide a mother-and-child type urine collection bag to solve the problems mentioned in the background art.

[0006] To address the above problems, this invention provides a mother-daughter type urine collection bag technical solution:

[0007] A mother-daughter type urine collection bag includes a mother bag and a daughter bag. A lower coupling seat is fixedly installed at the upper end of the mother bag, and an upper coupling seat is provided at the lower end of the daughter bag. A tension triggering component is provided between the upper coupling seat and the lower coupling seat. The tension triggering component includes a connector.

[0009] The lower coupling seat is provided with a lower sealing mechanism, which includes a flip sealing disc. The flip sealing disc is rotatably arranged inside the lower coupling seat, and the diameter of the flip sealing disc is the same as the diameter of the hole in the lower coupling seat.

[0010] Preferably, a plug ring is fixedly installed at the lower end of the upper coupling seat, the plug ring is inserted into the interior of the lower coupling seat, and a sealing ring is fixedly installed at the lower end of the plug ring. The sealing ring is slidably connected to the lower coupling seat, and the plug ring can position the connection between the upper coupling seat and the lower coupling seat.

[0011] Preferably, the tension triggering assembly further includes a reset pin, which is slidably connected inside the insertion tube.

The two ends of the trigger spring are fixedly connected to the damping disk and the pin head of the tension pin, respectively. The damping disk can increase the resistance of the tension pin. When the magnetic force between the first magnetic disk and the second magnetic disk is less than the elastic force of the trigger spring, the first magnetic disk and the second magnetic disk can be separated.

[0013] Preferably, a toggle bracket is fixedly installed on the outer side of the reset pin, and the toggle bracket is slidably connected to the elongated hole on the side of the insertion tube. A long-arm locking bracket is hinged to the inner bottom of the upper coupling seat, and the long-arm locking bracket is locked to the compression block.

One end of the compression spring is fixedly connected to the double guide rod frame, and the other end of the compression spring is fixedly connected to the compression block. During normal use of the sub-bag and the mother bag, the compression spring is compressed and stored by the compression block. After the magnetic disk one and magnetic disk two are separated, the compression spring pushes the compression block to compress and seal the flexible tube through its elastic force.

[0015] Preferably, an arc-shaped support block is fixedly installed on the inner wall of the upper coupling seat. The arc-shaped support block contacts the outer side of the flexible tube.

The second hanging strip can hang the mother bag on a hook below the bedside, and the first hanging strip can hang the daughter bag on a hook above the bedside.

[0019] The beneficial effects of this invention are:

[0020] This invention employs a tension triggering component between the upper and lower coupling seats, along with a connecting tube, damping disc, and trigger spring, to ensure a reliable connection between them under normal suspension. When the patient moves, turns over, or is subjected to nursing procedures, or when the urine bag is touched, causing instability in the suspension, a momentary or abnormal tension is generated at the connection point. Magnetic discs one and two can then promptly separate, detaching the upper and lower coupling seats and preventing the abnormal tension from being transmitted to the patient via the catheter, thereby reducing the risk of catheter displacement and urethral injury. The trigger spring's set elasticity is greater than the static load borne by the connection point under normal suspension, and the damping disc increases the resistance to movement of the tension pin, which helps reduce accidental triggering caused by slight shaking or normal nursing procedures.

[0021] This invention utilizes an upper sealing mechanism within the upper coupling seat. A flexible tube, an arc-shaped support block, a compression block, a double guide rod frame, a compression spring, a long-arm locking frame, a toggle frame, a fixing ring, and a support spring work together. When the tension triggering component actuates due to suspension instability, the long-arm locking frame disengages from the compression block. The compression spring then pushes the compression block to engage with the arc-shaped support block, compressing the flexible tube and quickly forming a seal on the sub-bag side. This prevents leakage of residual urine from the sub-bag and avoids the entry of external contaminants, improving hygiene and safety during use.

[0022] This invention features a lower sealing mechanism within the lower coupling seat. The mechanism utilizes a rotating sealing disc, a hinge frame, hinge ears, a torsion spring, and a storage groove in coordination. During normal connection, the rotating sealing disc is stored in the storage groove, without affecting urine drainage. If the upper and lower coupling seats separate due to abnormal tension, the torsion spring causes the rotating sealing disc to flip and seal the lower coupling seat opening, preventing urine leakage from the mother bag. The upper and lower sealing mechanisms respectively seal the daughter bag side and the mother bag side, achieving bidirectional leak prevention after separation, reducing the risk of contamination and infection, and facilitating reconnection and resetting.

[0036] like Figure 1-11 As shown, the specific implementation adopts the following technical solution:

[0037] Example:

[0038] A mother-daughter type urine collection bag includes a mother bag 1 and a daughter bag 2.

A tension triggering component 5 is provided between the upper coupling seat 3 and the lower coupling seat 4. The tension triggering component 5 includes a insertion tube 51. The insertion tube 51 is fixedly installed inside the upper coupling seat 3 and is inserted into the lower coupling seat 4. A second magnetic disk 55 is slidably connected inside the lower end of the insertion tube 51, and a first magnetic disk 53 is attracted to the upper end of the second magnetic disk 55. An upper sealing mechanism 7 is provided inside the upper coupling seat 3. The upper sealing mechanism 7 includes a flexible tube 71 and a compression block 73. The flexible tube 71 is fixedly installed inside the upper coupling seat 3, and the compression block 73 is provided on the outer side of the flexible tube 71.

The flip sealing disk 61 is rotatably arranged inside the lower coupling seat 4, and the diameter of the flip sealing disk 61 is the same as the diameter of the hole in the lower coupling seat 4.

[0039] The lower end of the upper coupling seat 3 is fixedly installed with a plug ring 31, which is inserted into the lower coupling seat 4. The lower end of the plug ring 31 is fixedly installed with a sealing ring 32, which is slidably connected to the lower coupling seat 4. The plug ring 31 can position the connection between the upper coupling seat 3 and the lower coupling seat 4.

[0040] The tension triggering component 5 also includes a reset pin 52. The reset pin 52 is slidably connected inside the insertion tube 51. A magnetic disk 53 is fixedly installed at the lower end of the reset pin 52. The magnetic disk 53 is slidably connected inside the insertion tube 51. A fixing disk 58 is fixedly installed in the lower middle part of the inner wall of the insertion tube 51. The fixing disk 58 is slidably connected to the pin rod of the reset pin 52. A storage spring 59 is provided on the outside of the pin rod of the reset pin 52. The two ends of the storage spring 59 are fixedly connected to the fixing disk 58 and the pin head of the reset pin 52, respectively. A pressing rod 510 is fixedly installed at the upper end of the reset pin 52. The pressing rod 510 passes through both the insertion tube 51 and the upper coupling seat 3 and is slidably connected to both. During the reset process, the pressing rod 510 can drive the reset pin 52 and the magnetic disk 53 to move downward.

[0041] The lower coupling seat 4 has a tension pin 54 slidably connected inside the groove. Magnetic disk 2 55 is fixedly installed on the upper end of the tension pin 54. A damping disk 56 is fixedly installed on the top of the inner wall of the groove of the lower coupling seat 4. The damping disk 56 is in contact with the magnetic disk 2 55. The pin rod of the tension pin 54 is slidably connected to the damping disk 56. A trigger spring 57 is provided on the outside of the pin rod of the tension pin 54. The two ends of the trigger spring 57 are fixedly connected to the damping disk 56 and the pin head of the tension pin 54, respectively. The damping disk 56 can increase the resistance of the tension pin 54. When the magnetic force between magnetic disk 1 53 and magnetic disk 2 55 is less than the elastic force of the trigger spring 57, magnetic disk 1 53 and magnetic disk 2 55 can be separated.

[0042] Among them, a toggle bracket 512 is fixedly installed on the outside of the reset pin 52. The toggle bracket 512 is slidably connected to the elongated hole on the side of the insertion tube 51. A long arm locking bracket 511 is hinged to the bottom inner side of the upper coupling seat 3. The long arm locking bracket 511 is locked to the pressing block 73. The side of the long arm locking bracket 511 away from the pressing block 73 is in contact with the toggle bracket 512. A fixing ring 513 is fixedly installed on the bottom inner side of the upper coupling seat 3 and below the long arm locking bracket 511. A support spring 514 is provided inside the fixing ring 513. One end of the support spring 514 is fixedly connected to the fixing ring 513. The other end of the support spring 514 is fixedly installed in the groove below the long arm locking bracket 511. The support spring 514 can support the long arm locking bracket 511 with its elastic force. The long arm locking bracket 511 can lock the pressing block 73.

[0043] The upper sealing mechanism 7 also includes a double guide rod frame 74. The double guide rod frame 74 is fixedly installed on the inner bottom of the upper coupling seat 3. The compression block 73 is slidably connected to the outer side of the double guide rod frame 74. Compression springs 75 are provided on the outer sides of the two rods of the double guide rod frame 74. One end of the compression spring 75 is fixedly connected to the double guide rod frame 74, and the other end of the compression spring 75 is fixedly connected to the compression block 73. During normal use of the sub-bag 2 and the mother bag 1, the compression spring 75 is compressed and stored by the compression block 73. After the magnetic disk 1 53 and the magnetic disk 2 55 are separated, the compression spring 75 pushes the compression block 73 to compress and seal the flexible tube 71 through its elastic force.

[0044] Among them, an arc-shaped support block 72 is fixedly installed on the inner wall of the upper coupling seat 3. The arc-shaped support block 72 contacts the outer side of the flexible tube 71. A reset push rod 76 is fixedly installed on the upper end of the extrusion block 73. The reset push rod 76 is slidably connected to the waist hole above the upper coupling seat 3. The flexible tube 71 can be deformed by the cooperation of the arc-shaped support block 72 and the extrusion block 73. After deformation, the flexible tube 71 can be sealed.

[0045] The lower sealing mechanism 6 also includes a hinge frame 62. The hinge frame 62 is fixedly installed on the upper end of the lower coupling seat 4. Two symmetrically distributed hinge ears 63 are hinged to the outer side of the central rod of the hinge frame 62. Both hinge ears 63 are fixedly installed on the outer side of the flip sealing disc 61. A torsion spring 64 is provided on the outer side of the central rod of the hinge frame 62. One end of the torsion spring 64 is fixedly connected to the flip sealing disc 61, and the other end of the torsion spring 64 is fixedly connected to the hinge frame 62. A storage groove 65 is opened at the upper end of the lower coupling seat 4. The upper surface of the flip sealing disc 61 is in contact with the lower surface of the upper coupling seat 3. When the upper coupling seat 3 and the lower coupling seat 4 are in contact, the flip sealing disc 61 can slide into the storage groove 65 for storage.

[0046] The upper coupling seat 3 and the lower coupling seat 4 are in contact. A discharge valve 9 is fixedly installed at the lower end of the mother bag 1, and a sealing valve 8 is fixedly installed at the lower end of the daughter bag 2. The upper coupling seat 3 is fixedly installed at the lower end of the sealing valve 8. The discharge valve 9 can discharge and sample the urine inside the mother bag 1. A second hanging strip 12 is fixedly installed on the back of the mother bag 1, and a first hanging strip 11 is fixedly installed on the back of the daughter bag 2. A catheter 10 is fixedly installed at the upper end of the daughter bag 2. The second hanging strip 12 can hang the mother bag 1 on the hook below the bed, and the first hanging strip 11 can hang the daughter bag 2 on the hook above the bed.

[0047] The invention is used as follows: During normal use, the catheter 10 at the upper end of the sub-bag 2 introduces urine. The urine enters the upper coupling seat 3 and the insertion tube 51 through the sealing valve 8, and then enters the lower coupling seat 4 and the mother bag 1. The insertion ring 31 at the lower end of the upper coupling seat 3 is inserted into the lower coupling seat 4. The sealing ring 32 slides with the lower coupling seat 4 to achieve positioning and sealing. At this time, the magnetic disk 1 53 and the magnetic disk 2 55 are attracted to each other. The tension pin 54 is constrained by the trigger spring 57 and the damping disk 56, and the upper coupling seat 3 and the lower coupling seat 4 remain connected. The flip sealing disk 61 is pressed into the storage groove 65 by the lower surface of the upper coupling seat 3. The long arm clamping bracket 511 clamps the squeezing block 73 under the action of the support spring 514. The squeezing spring 75 is in a stored state, the flexible tube 71 remains unobstructed, and the suspension strip 1 11 and the suspension strip 2 12 respectively suspend and fix the sub-bag 2 and the mother bag 1.

[0048] When the patient moves, turns over, is subjected to nursing procedures, or the urine bag is touched, the direction or position of the force on the suspension strip 11 and suspension strip 12 changes, generating a momentary or abnormal tension between the daughter bag 2 and the mother bag 1. This tension is transmitted through the upper coupling seat 3, the insertion tube 51, the magnetic disk 1 53, the magnetic disk 2 55, and the tension pin 54. When this tension exceeds the attraction force between the magnetic disk 1 53 and the magnetic disk 2 55 and the set elastic force of the trigger spring 57, the magnetic disk 2 55 overcomes the resistance of the damping disk 56 and separates from the magnetic disk 1 53. The upper coupling seat 3 and the lower coupling seat 4 then disengage, preventing the abnormal tension from being transmitted to the catheter 10 and avoiding traction on the urethra.

[0049] After the magnetic disk 1 53 and magnetic disk 2 55 separate, the storage spring 59 is released, pushing the reset pin 52 and the actuating frame 512 fixed on the reset pin 52 to move. The actuating frame 512 drives the long arm locking frame 511 to rotate around the hinge, so that the long arm locking frame 511 is released from the clamping block 73. Then the clamping spring 75 pushes the clamping block 73 to move along the double guide rod frame 74. The clamping block 73 and the arc-shaped support block 72 cooperate to squeeze the flexible tube 71. The flexible tube 71 deforms and forms a seal, thereby blocking the leakage of urine from the second side of the sub-bag. The reset push rod 76 can be used for subsequent reset operations.

[0050] After the upper coupling seat 3 leaves the lower coupling seat 4, the flip sealing disc 61 loses the limit of the lower surface of the upper coupling seat 3. The torsion spring 64 drives the flip sealing disc 61 to rotate around the central rod of the hinge frame 62 through the hinge ear 63, so that the flip sealing disc 61 rotates out of the storage groove 65 and seals the hole of the lower coupling seat 4 to prevent urine from leaking out of the mother bag 1.

[0051] During reconnection, pressing the lever 510 causes the reset pin 52 and magnetic disk 53 to move downwards, and the reset push rod 76 causes the squeezing block 73 to retract. The long arm clamping bracket 511, under the action of the support spring 514, re-clamps the squeezing block 73. Then, the upper coupling seat 3 is inserted into the lower coupling seat 4, and the flipped sealing plate 61 is pushed back into the storage groove 65 by the upper coupling seat 3. Magnetic disk 53 and magnetic disk 55 are re-adsorbed, and normal drainage can be restored.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
