Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a leak-proof urine bag and a fixing device thereof. Background Art

[0002] A urine bag is an important medical device specially used to collect and store the patient's urine. It is usually made of soft and leak-proof materials, and is designed with a detachable bag and a pipe connecting the bag to the body. This design allows the urine bag to be fixed on the patient, facilitating the drainage and collection of urine. Urine bags are widely used in hospitals, nursing institutions and home care, especially for patients who need long-term indwelling catheters or cannot urinate independently. Through the catheter, the patient's urine can be smoothly drained from the bladder into the urine bag, effectively avoiding the health risks that may be caused by urine retention in the body. In the use of existing urine bags, it is easy for patients to ignore the penetration observation of the urine bag, resulting in the failure to replace the urine bag in time after it is full, thus affecting the patient's physical health. The main reasons for patients ignoring the observation of the urine bag are:

[0003] 1. Certain neurological diseases or injuries can weaken the patient's sense of touch, vision and other sensory abilities, making it difficult for them to accurately perceive changes in the volume of the urine bag. This weakening or loss of perception makes it impossible for the patient to detect the filling status of the urine bag in time, thus missing the best time to change the urine bag;

[0004] 2. Patients may temporarily ignore the existence of the urine bag in their daily lives because they are busy with other matters, or completely lose attention to the status of the urine bag during sleep. These moments of distraction, as well as the natural decrease in alertness during sleep, increase the possibility of the urine bag overflowing without being discovered in time, which in turn has an adverse effect on the patient's comfort and health;

[0005] For this reason, we propose a leak-proof urine bag and a fixing device thereof. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 12 The present invention provides a technical solution: a leak-proof urine bag and a fixing device thereof, comprising a bag body 1 and a joint 2, and also comprising a snap-in plate 3, wherein the snap-in plate 3 is located on the joint 2.

[0037] The self-sealing member 4 is arranged on the joint 2, and the self-sealing member 4 is used to automatically seal the joint 2 when the joint 2 is detached.

[0038] The self-sealing part 4 includes a rotating rod 41 rotatably arranged on the joint 2, a blocking block 42 is arranged at one end of the rotating rod 41 located inside the joint 2, and the blocking block 42 is hemispherical. A pushing rod 43 is arranged at one end of the rotating rod 41 away from the blocking block 42, and a torsion spring 44 is sleeved on the rotating rod 41, and the torsion spring 44 is connected to the joint 2.

[0039] The benefit of the self-sealing member 4 is that it can automatically seal the joint 2 after the bag body 1 reaches the upper capacity limit and leaves the switching chamber 92, thereby effectively preventing urine in the bag body 1 from overflowing.

[0040] A fixing device for a leak-proof urine bag comprises a fixing belt 5 and a storage bin 6 arranged on the fixing belt 5, and also comprises a transfer tube 7. The transfer tube 7 is arranged on the storage bin 6 and is used to change the flow direction of urine after the bag body 1 is filled with urine.

[0041] The detaching assembly 8 is arranged on the storage bin 6, and is used to control the transfer tube 7 to rotate after the bag body 1 is filled with urine, thereby changing the flow direction of urine.

[0042] The disengagement assembly 8 includes a switching member 9 arranged on the placement bin 6, and the switching member 9 is used to drive the transfer tube 7 to rotate, thereby changing the flow direction of urine. The placement bin 6 is provided with a driving member 10, and the driving member 10 is used to provide power for the switching member 9. The switching member 9 is provided with a docking member 11, and the docking member 11 is used to fix the connector 2 on the bag body 1 to the switching member 9. The placement bin 6 is provided with a disengagement member 12, and the disengagement member 12 is used to control the bag body 1 and the connector 2 to disengage from the switching member 9 after the bag body 1 is filled with urine.

[0043] The advantage of the detachment component 8 is that it can automatically detect the filling state of the urine bag and automatically switch to a new urine bag when the upper capacity limit is reached, without the patient relying on touch or vision to determine whether the urine bag needs to be replaced, which greatly reduces the burden on patients and allows them to keep the urine bag clean and comfortable even when their perception is limited. At the same time, since patients may not be able to accurately perceive the capacity changes of the urine bag, the automatic switching design avoids the overflow of the urine bag due to patient misjudgment, which helps reduce the risk of urine leakage and maintain the dignity and comfort of the patient. Finally, once it is detected that the urine bag is about to overflow, the design will immediately start the detachment component 8 to drain the urine into the new urine bag and seal the filled urine bag. This immediate response helps to avoid urine leakage and patient discomfort.

[0044] The switching member 9 includes a fixed plate 91 arranged in the placement bin 6, a switching bin 92 is arranged on the fixed plate 91, a vertical rod 93 used in conjunction with the push rod 43 is arranged on the outer side of the switching bin 92, the switching bin 92 is rotatably connected to the transfer tube 7, a circular groove 94 is provided in the switching bin 92, the circular groove 94 is slidably connected to the transfer tube 7, a plurality of transfer grooves 95 used in conjunction with the transfer tube 7 are provided in the circular groove 94, a rotating plate 96 is rotatably arranged in the circular groove 94, the rotating plate 96 is connected to the transfer tube 7, a sealing plate 97 used in conjunction with the transfer groove 95 is provided on the side of the rotating plate 96 away from the transfer tube 7, and a sponge pad 98 is provided on the side of the sealing plate 97 in contact with the circular groove 94.

[0045] The advantage of the switching member 9 is that it can automatically control the transfer tube 7 to switch when a single bag body 1 reaches the maximum capacity. The automatic switching function reduces the need for the patient or caregiver to manually replace the leaking urine bag, thereby reducing the difficulty and inconvenience of operation. At the same time, the automatic blocking function can prevent urine leakage and reduce the contact of urine with the patient's skin, clothing or the surrounding environment, thereby reducing the risk of cross infection.

[0046] The driving member 10 includes a bearing plate 101 rotatably arranged on the placement bin 6, a magnet 102 is arranged on the bearing plate 101, a magnet 2 103 which attracts the magnet 102 is arranged on the placement bin 6, a traction rope 104 is arranged on the bearing plate 101, a guide tube 105 is arranged on the fixed plate 91, a driving rack 106 is slidably arranged in the guide tube 105, a return spring 107 is arranged in the guide tube 105, one end of the return spring 107 is connected to the driving rack 106, the traction rope 104 passes through the guide tube 105 and the return spring 107 and is connected to the driving rack 106, and the traction rope 104 is movably connected to the guide tube 105, a steering gear 108 used in conjunction with the driving rack 106 is arranged on the transfer tube 7, the steering gear 108 is connected to the transfer tube 7 through a one-way bearing, and the driving rack 106 and the steering gear 108 are both made of plastic.

[0047] When in use, first put the bag body 1 in the folded state into the placement chamber 6, which can be opened from the side, which is the prior art, then engage the joint 2 with the adapter groove 95, and then push the limit rods 112 on both sides of the joint 2 to rotate and squeeze the clamping plate 3, so as to complete the fixation of the bag body 1 and the joint 2. During the continuous use of the bag body 1, urine is continuously poured into the bag body 1, so that the urine in the bag body 1 gradually increases, and the bag body 1 gradually stretches under the infusion of urine. When the urine in the bag body 1 reaches When the capacity reaches the limit, the magnet 102 on the supporting plate 101 separates from the magnet 2 103 under the pressure of gravity, causing the supporting plate 101 to flip over. When the supporting plate 101 flips over, the traction rope 104 is driven to move, and the movement of the traction rope 104 drives the driving rack 106 to move. The movement of the driving rack 106 drives the steering gear 108 to rotate, and the rotation of the steering gear 108 drives the transfer tube 7 to rotate, thereby achieving the function of switching the bag body 1, and the vacant transfer slot 95 will be re-blocked by the blocking plate 97.

[0048] The docking member 11 includes a docking seat 111 rotatably set on the switching bin 92, and the docking seat 111 is located on both sides of the adapter groove 95, a limiting rod 112 is rotatably set on the docking seat 111 for use with the clamping plate 3, and a rubber pad 113 is set on the side of the clamping plate 3 that contacts the limiting rod 112, the limiting rod 112 is L-shaped, and a torsion spring 114 is sleeved on the docking seat 111, and the torsion spring 114 is respectively connected to the limiting rod 112 and the docking seat 111.

[0049] The disengagement member 12 includes a supporting plate 121 rotatably arranged on the placement bin 6, a magnet 122 is arranged on the supporting plate 121, a magnet 123 that attracts the magnet 122 is arranged on the placement bin 6, pull ropes 124 are arranged on both sides of the supporting plate 121, a plurality of guide rods 125 are arranged on the placement bin 6 and the switching bin 92, the pull rope 124 passes through the guide rod 125 and is connected to the limit rod 112, and the pull rope 124 is movably connected to the guide rod 125.

[0050] The advantage of setting up the separation piece 12 is that it can allow the filled bag body 1 to automatically fall off from the switching bin 92. Timely falling off also reduces the chance of bacterial growth and infection caused by long-term retention, and is easy to collect and dispose of, reducing the cumbersome steps in the nursing process.

[0051] When the carrier plate 101 flips over, the bag body 1 falls on the carrier plate 2 121. At this time, the magnet 3 122 on the carrier plate 2 121 is separated from the magnet 4 123 under the action of gravity, so that the carrier plate 2 121 is also flipped under the pressure of the bag body 1. When the carrier plate 2 121 flips over, it drives the pull rope 124 to move. The movement of the pull rope 124 drives the limit rod 112 connected to it to rotate, so that the clamping plate 3 is separated from the limit rod 112. At this time, the bag body 1 is separated from the switching bin 92 under the action of gravity, and the push rod 43 is separated from the vertical rod 93. After the push rod 43 is separated from the vertical rod 93, it drives the blocking block 42 to rotate under the action of the torsion spring 2 114 to block the joint 2, thereby preventing urine in the bag body 1 from leaking.

[0052] The pull rope 124 and the traction rope 104 are made of polyester fiber. The polyester fiber material has better strength and wear resistance, and can effectively extend the service life of the pull rope 124 and the traction rope 104.

[0053] When in use, first put the bag body 1 in the folded state into the placement chamber 6, which can be opened from the side, which is the prior art, then engage the joint 2 with the adapter groove 95, and then push the limit rods 112 on both sides of the joint 2 to rotate and squeeze the clamping plate 3, so as to complete the fixation of the bag body 1 and the joint 2. During the continuous use of the bag body 1, urine is continuously poured into the bag body 1, so that the urine in the bag body 1 gradually increases, and the bag body 1 gradually stretches under the infusion of urine. When the urine in the bag body 1 reaches When the capacity reaches the limit, the magnet 102 on the supporting plate 101 separates from the magnet 2 103 under the pressure of gravity, causing the supporting plate 101 to flip over. When the supporting plate 101 flips over, the traction rope 104 is driven to move, and the movement of the traction rope 104 drives the driving rack 106 to move. The movement of the driving rack 106 drives the steering gear 108 to rotate, and the rotation of the steering gear 108 drives the transfer tube 7 to rotate, thereby achieving the function of switching the bag body 1, and the vacant transfer slot 95 will be re-blocked by the blocking plate 97.

[0054] When the carrier plate 101 flips over, the bag body 1 falls on the carrier plate 2 121. At this time, the magnet 3 122 on the carrier plate 2 121 is separated from the magnet 4 123 under the action of gravity, so that the carrier plate 2 121 is also flipped under the pressure of the bag body 1. When the carrier plate 2 121 flips over, it drives the pull rope 124 to move. The movement of the pull rope 124 drives the limit rod 112 connected to it to rotate, so that the clamping plate 3 is separated from the limit rod 112. At this time, the bag body 1 is separated from the switching bin 92 under the action of gravity, and the push rod 43 is separated from the vertical rod 93. After the push rod 43 is separated from the vertical rod 93, it drives the blocking block 42 to rotate under the action of the torsion spring 2 114 to block the joint 2, thereby preventing urine in the bag body 1 from leaking.

[0055] Example 2: Please refer to Fig.13 The present invention provides a technical solution: an observation window 13 is provided on the storage bin 6, and the setting of the observation window 13 is convenient for medical staff to observe the urine status of the patient.
