Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a urinary catheter assembly for preventing unplanned extubation. Background Technology

[0002] A urinary catheter, made of natural rubber, silicone rubber, or polyvinyl chloride (PVC), is a tube inserted into the bladder through the urethra to drain urine. After insertion, a balloon near the tip of the catheter secures it within the bladder, and a drainage tube connects to a urine bag to collect urine. Clinically, when the catheter is subjected to external force, the balloon can dislodge, leading to unplanned extubation. To prevent this, a fixation component is used to further secure the catheter. However, a significant gap exists between the fixation component and the catheterization site. When the catheter segment within this gap is subjected to external force, the balloon at the other end, connected to the fixation component, is more likely to dislodge, thus necessitating measures to prevent unplanned extubation.

[0003] In existing technologies, such as the utility model CN213698474U urinary catheter fixation device, the fixing patch is attached to the human thigh with an adhesive layer, and the urinary catheter is connected to the fixing patch with an adhesive tape to distribute the force of the urinary catheter. However, there is a large gap between the fixing patch and the catheterization site. When the urinary catheter segment located in the gap is subjected to external force, the balloon located at the other end of the urinary catheter is more likely to fall out of the body because one end of the urinary catheter is connected to the fixing patch.

[0004] Therefore, how to avoid unplanned extubation is an urgent problem to be solved in this technical field. Utility Model Content

[0005] To address the shortcomings of current catheters where a large gap exists between the fixation component and the catheterization site, causing the balloon at the other end of the catheter to more easily detach from the body when subjected to external forces due to the connection between one end of the catheter and the fixation component, this invention provides a catheter assembly that restricts the movement of the catheter through a locking component. This eliminates the gap between the fixed position of the catheter and the catheterization site, preventing the balloon within the catheterization site from detaching from the body under external forces and thus avoiding unplanned catheter removal.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A urinary catheter assembly for preventing unplanned extubation includes a belt for fastening around a patient's hip, and further includes:

[0008] Two adjustment straps are attached to the waist belt and are designed to fit against the patient's groin area.

[0009] A locking assembly is connected between the two adjustment bands and is used to limit and fix the catheter exposed at the catheterization site.

[0010] As a preferred embodiment, the card engagement component includes:

[0011] The lower arc-shaped block has its two sides fixedly connected to the two adjustment belts respectively;

[0012] An upper arc-shaped block is hinged to one side of a lower arc-shaped block, and the other side of the upper arc-shaped block is snapped together with the other side of the lower arc-shaped block, so that the catheter is limited and fixed after the upper arc-shaped block and the lower arc-shaped block are snapped together.

[0013] As a preferred embodiment, positioning straps are also connected to both sides of the lower arc-shaped block. The beginning and end of the positioning straps are connected by Velcro I. The positioning straps are used to wrap around the patient's groin to restrict the movement of the lower arc-shaped block.

[0014] In a preferred embodiment, the adjustment belt includes a connecting section and an adjustment section. One end of the connecting section is fixedly connected to the front side of the waist belt, and the other end of the connecting section is connected to a hook I. One end of the adjustment section is fixedly connected to the rear side of the waist belt, and the adjustment section is inserted into the hook I. The head and tail of the adjustment section are connected by Velcro II.

[0015] As a preferred embodiment, the belt includes:

[0016] A front belt body, with hooks II connected to both ends of the front belt body, and the front belt body is fixedly connected to the connecting section;

[0017] The rear strap is fixedly connected to the adjustment section. The two ends of the rear strap are respectively inserted into the hook II. The two ends of the rear strap are connected to the middle part by Velcro III.

[0018] As a preferred embodiment, a silicone pad I is provided on the inner side of the waist belt.

[0019] As a preferred embodiment, a silicone pad II is provided on the inner side of the adjustment belt.

[0020] As a preferred embodiment, a silicone pad III is provided on the inner side of the positioning band.

[0021] As a preferred embodiment, an arc-shaped anti-slip pad I is provided on the inner side of the lower arc-shaped block, and an arc-shaped anti-slip pad II is provided on the inner side of the upper arc-shaped block. The arc-shaped anti-slip pad I, together with the arc-shaped anti-slip pad II, is used to prevent the catheter from sliding.

[0022] In a preferred embodiment, the lower arc-shaped block is also connected to a buffer band via a cable. The head and tail of the buffer band are connected by Velcro IV. The buffer band is used to wrap around the thigh. A silicone strip and multiple limiting bands are also provided on the outside of the buffer band. The limiting bands are connected to the buffer band by Velcro V. The limiting bands are used to fix the catheter segment to the silicone strip, so that when the catheter is subjected to external force, the silicone strip and the limiting bands provide cushioning.

[0023] By adopting the above-mentioned technology, the beneficial effects of this utility model compared with the prior art are as follows:

[0024] This invention uses a waist belt and two adjustment straps to fix the locking component to the outside of the catheterization site. The locking component also restricts the movement of the catheter, ensuring that there is no gap between the fixed position of the catheter and the catheterization site. The balloon inside the catheterization site will not fall out of the body when subjected to external force, thus avoiding unplanned catheter removal. Attached Figure Description

[0034] Examples, such as Figures 1-4 As shown,

[0035] A urinary catheter assembly for preventing unplanned extubation includes a waist belt 1 for fastening around the patient's hip, characterized in that it further comprises:

[0036] Two adjustment straps 2 are attached to the waist belt 1 and are used to fit against the patient's groin.

[0037] The locking component 3 is connected between the two adjustment bands 2 and is used to limit and fix the catheter exposed at the catheterization site.

[0038] When performing catheterization, the catheter is inserted into the patient's catheterization site. A waist belt 1 is then fastened around the patient's hips, and two adjusting straps 2 are positioned close to the inner sides of the patient's two inner thighs. A locking assembly 3 is used to secure the catheter exposed at the catheterization site. The waist belt 1 and the two adjusting straps 2 restrict the vertical movement of the locking assembly 3, preventing it from shifting relative to the catheterization site. The locking assembly 3 is also positioned close to the outer side of the catheterization site, restricting the catheter's movement. Therefore, when the catheter segment is subjected to external force, the balloon located within the catheterization site will not dislodge from the body. In this technical solution, the waist belt 1 and the two adjusting straps 2 work together to secure the locking assembly 3 to the outer side of the catheterization site. The locking assembly 3 further restricts the catheter's movement, ensuring a seamless connection between the catheter and the catheterization site. This prevents the balloon within the catheterization site from dislodging from the body under external force, avoiding unplanned catheter removal.

[0039] In a preferred embodiment, the locking component 3 includes:

[0040] The lower arc-shaped block 31 is fixedly connected to the two adjustment belts 2 on both sides;

[0041] The upper arc-shaped block 32 has one side hinged to one side of the lower arc-shaped block 31, and the other side of the upper arc-shaped block 32 is snapped to the other side of the lower arc-shaped block 31, so that the catheter is limited and fixed after the upper arc-shaped block 32 and the lower arc-shaped block 31 are snapped together.

[0042] The waist belt 1 is fastened around the patient's hips, and the two adjustment straps 2 are placed tightly against the inner sides of the patient's two thigh roots. The buckle connection between the upper arc-shaped block 32 and the lower arc-shaped block 31 is then removed. The catheter segment is then inserted into the lower arc-shaped block 31. The upper arc-shaped block 32 and the lower arc-shaped block 31 are then buckled together. The catheter is clamped by the cooperation between the inner walls of the lower arc-shaped block 31 and the upper arc-shaped block 32. The friction between the lower arc-shaped block 31 and the upper arc-shaped block 32 limits and fixes the catheter to prevent movement and displacement.

[0043] As a preferred embodiment, positioning straps 4 are also connected to both sides of the lower arc-shaped block 31. The head and tail of the positioning straps 4 are connected by Velcro I 41. The positioning straps 4 are used to wrap around the patient's groin to restrict the movement of the lower arc-shaped block 31.

[0044] When the locking component 3 is tightly fitted to the outside of the catheterization site through the cooperation of the waist belt 1 and the two adjustment straps 2, the locking component 3 will shift left and right with the patient's movements. The left and right displacement of the locking component 3 will cause the catheter to move, causing discomfort to the patient. Therefore, positioning straps 4 are connected to both sides of the lower arc block 31. After the position of the locking component 3 is restricted by the cooperation of the waist belt 1 and the two adjustment straps 2, the positioning straps 4 are wrapped around the patient's groin. The head and tail of the positioning straps 4 are connected by Velcro I 41. The connection between the positioning straps 4 and the patient's groin restricts the left and right movement of the locking component 3, so that the locking component 3 cannot shift left and right with the patient's movements, thus avoiding discomfort to the patient.

[0045] In a preferred embodiment, the adjustment belt 2 includes a connecting section 21 and an adjustment section 22. One end of the connecting section 21 is fixedly connected to the front side of the waist belt 1, and the other end of the connecting section 21 is connected to a hook I 23. One end of the adjustment section 22 is fixedly connected to the rear side of the waist belt 1, and the adjustment section 22 is inserted into the hook I 23. The head and tail of the adjustment section 22 are connected by Velcro II 24.

[0046] Different patients have different physiological characteristics, thus requiring fine adjustments to the connection position of the locking component 3. Therefore, the adjustment belt 2 is configured to consist of a connecting section 21 and an adjustment section 22. After the waist belt 1 is fastened around the patient's hips, the adjustment section 22 is threaded into the hook I 23 and tightened so that it fits snugly against the inner side of the patient's inner thigh. Then, the head and tail of the adjustment section 22 are connected by Velcro II 24, allowing the locking component 3 to adapt to patients with different physiological characteristics and improving its applicability.

[0047] As a preferred embodiment, the belt 1 includes:

[0048] The front belt body 11 has hooks II 12 connected to both ends of the front belt body 11, and the front belt body 11 is fixedly connected to the connecting section 21.

[0049] The rear strap 13 is fixedly connected to the adjustment section 22. The two ends of the rear strap 13 are respectively inserted into the hook II 12. The two ends of the rear strap 13 are connected to the middle part by Velcro III 14.

[0050] Since different patients have different waist and hip positions, the waist belt 1 needs to be able to fit different patients. Therefore, the waist belt 1 is designed to consist of a front belt body 11 and a back belt body 13. The front belt body 11 and the back belt body 13 are connected by a hook II 12 and a Velcro strap III 14. When in use, the back belt body 13 is placed under the patient's back, the front belt body 11 is placed under the patient's abdomen, and the two ends of the back belt body 13 are respectively inserted into the hook II 12. After tightening the two ends of the back belt body 13, the two ends of the back belt body 13 are connected to the middle through the Velcro strap III 14. This allows it to fit different patients and is also convenient for medical staff to operate.

[0051] Furthermore, a silicone pad I15 is provided on the inner side of the waist belt 1.

[0052] Furthermore, a silicone pad II 25 is provided on the inner side of the adjustment belt 2.

[0053] Furthermore, a silicone pad Ⅲ42 is provided on the inner side of the positioning band 4.

[0054] The anti-slip and skin-friendly properties of the waist belt 1 are improved by silicone pad I15, the anti-slip and skin-friendly properties of the adjustment belt 2 are improved by silicone pad II25, and the anti-slip and skin-friendly properties of the positioning belt 4 are improved by silicone pad III42, thereby ensuring connection stability while ensuring patient comfort.

[0055] As a preferred embodiment, an arc-shaped anti-slip pad I 33 is provided on the inner side of the lower arc-shaped block 31, and an arc-shaped anti-slip pad II 34 is provided on the inner side of the upper arc-shaped block 32. The arc-shaped anti-slip pad I 33 works in conjunction with the arc-shaped anti-slip pad II 34 to prevent the catheter from sliding.

[0056] By setting an arc-shaped anti-slip pad I 33 on the inner side of the lower arc-shaped block 31, the friction force on the inner side of the lower arc-shaped block 31 is increased, while the inner side of the lower arc-shaped block 31 has a certain degree of flexibility, thus avoiding friction damage to the catheter segment caused by the inner side of the lower arc-shaped block 31. By setting an arc-shaped anti-slip pad II 34 on the inner side of the upper arc-shaped block 32, the friction force on the inner side of the upper arc-shaped block 32 is increased, while the inner side of the upper arc-shaped block 32 has a certain degree of flexibility, thus avoiding friction damage to the catheter segment caused by the inner side of the upper arc-shaped block 32. After the arc-shaped anti-slip pad I 33 and the arc-shaped anti-slip pad II 34 clamp the catheter segment, the friction force can effectively limit the movement of the catheter, ensuring the flow performance of the catheter while avoiding friction damage to the catheter.

[0057] In a preferred embodiment, the lower arc-shaped block 31 is also connected to a buffer band 51 via a cable 5. The head and tail of the buffer band 51 are connected by Velcro IV. The buffer band 51 is used to wrap around the thigh. A silicone strip 52 and multiple limiting bands 53 are also provided on the outside of the buffer band 51. The limiting bands 53 are connected to the buffer band 51 by Velcro V 54. The limiting bands 53 are used to fix the catheter segment to the silicone strip 52, so that when the catheter is subjected to external force, it is buffered by the silicone strip 52 and the limiting bands 53.

[0058] When the catheter is subjected to a large external force, it can cause the locking assembly 3 to shift, resulting in displacement of the balloon within the catheterization site. In severe cases, this can lead to the catheter detaching from the catheterization site. Therefore, the lower arc-shaped block 31 is connected to the buffer strip 51 via cable 5. A silicone strip 52 and multiple limiting straps 53 are installed on the outer side of the buffer strip 51. The limiting straps 53 are connected to the buffer strip 51 via Velcro V 54, thus fixing the catheter segment to the silicone strip 52. When the catheter is subjected to a large external force, the silicone strip 52 and the limiting straps 53 provide cushioning. The silicone strip 52 cushions the axial force on the catheter, while the limiting straps 53, connected to the buffer strip 51 via Velcro V 54, cushion the lateral force on the catheter. This prevents unplanned catheter removal when the external force on the catheter is large.

[0059] The above description is merely a preferred embodiment of the utility model and is not intended to limit the technical solution of the utility model. For those skilled in the art, the utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the technical solution of the utility model should be included within the protection scope of the utility model.
