Description

Technical Field

[0001] This application relates to the technical field of medical appliances, and specifically, to a urinary catheter fixator. Background Art

[0002] A urinary catheter is a tube inserted into the bladder through the urethra for urine drainage. It is made of natural rubber, silicone rubber, or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an airbag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily. The drainage tube is connected to a urine bag to collect urine. When using a urinary catheter, in order to reduce the discomfort caused by the shaking to the patient, a fixator is often used to fix the long rubber tube of the urinary catheter outside the human body on the human body.

[0003] The Chinese utility model patent with the publication number CN215024822U discloses an elastic urinary catheter fixator. It drives an elastic metal sheet through an adjustable slider to press and fix urinary catheters with different diameters by changing the shape, so as to fix it on the human body and achieve the effect of reducing the discomfort of patients. However, due to the different lengths of urinary catheters and the different body postures of patients, the contact part of the above device with the urinary catheter is only the cross-sectional part of the elastic metal sheet. This may lead to the situation that the urinary catheter is too long to be accommodated. After the urinary catheter is fixed on the human body, the overly long urinary catheter exposed outside will cause inconvenience to the patient when lying or walking. If there are situations such as tube entanglement or extrusion, it may also cause damage to the patient's body.

[0004] Therefore, this application provides a urinary catheter fixator to solve the above problems. Utility Model Content

[0005] This application provides a urinary catheter fixator, aiming to solve the problems in the background art that due to the different lengths of urinary catheters and the different body postures of patients, the contact part of the above device with the urinary catheter is only the cross-sectional part of the elastic metal sheet. This may lead to the situation that the urinary catheter is too long to be accommodated. After the urinary catheter is fixed on the human body, the overly long urinary catheter exposed outside will cause inconvenience to the patient when lying or walking. If there are situations such as tube entanglement or extrusion, it may also cause damage to the patient's body.

[0006] To achieve the above object, this application provides the following technical solution: A urinary catheter fixator includes a fitting plate for fixing the urinary catheter body on the leg and a strap for binding the fitting plate to the leg. The fitting plate is provided with a storage and fixing mechanism for protecting the rubber tube part of the urinary catheter body;

[0007] The storage and fixing mechanism includes a storage cavity that penetrates through both ends on the outer wall of the fitting plate. In the storage cavity, a groove plate is installed through an adjusting member. The groove plate is used to adjust the storage length of the rubber tube part of the urinary catheter body, and both ends of the groove plate are arc-shaped, and the height of the top is not higher than the height of the storage cavity. There are two pipe-passing cavities with equal widths and adapted to the diameter of the rubber tube part of the urinary catheter body left between the straight sides of the groove plate and the two opposite inner side walls of the fitting plate in the storage cavity. The top of the storage cavity is hinged with a cover plate. In this way, when wearing the urinary catheter body, the fitting plate is tied to a suitable position on the patient's leg through a strap. Then, the cover plate is opened, and the rubber tube part of the urinary catheter body remaining outside the human body is bent into a U shape adapted to the groove plate and pressed into the pipe-passing cavity from above, so that the bent part of the rubber tube part of the urinary catheter body fits the groove plate, and the storage length is adjusted through the adjusting member. Then, the cover plate is covered to cover and protect the rubber tube part of the urinary catheter body. Compared with the existing urinary catheter fixator, it solves the problem that the too long external tube body exposed outside will bring inconvenience to the patient's lying and walking, making the patient more comfortable and safe when wearing.

[0008] Preferably, in order to adjust the position of the groove plate, the adjusting member includes a chute opened at the bottom of the storage cavity on the fitting plate. A lead screw is movably installed in the chute. One end of the lead screw penetrates through the fitting plate and extends outward, and a knob is fixedly installed at the end. A slider that is adapted to the chute and fixedly connected to the bottom of the groove plate is screwed on the outer side wall of the lead screw in the chute. By rotating the knob to drive the lead screw to rotate, the slider and the groove plate fixed to the slider are driven to move toward one side in the storage cavity, driving the rubber tube part of the urinary catheter body stuck in the pipe-passing cavity to contract into the storage cavity on the fitting plate, so as to take in the too long rubber tube part of the urinary catheter body into the storage cavity. Rotating the knob in the other rotation direction drives the lead screw to rotate, thereby driving the slider and the groove plate fixed to the slider to move toward the other side in the storage cavity, driving the rubber tube part of the urinary catheter body stuck in the pipe-passing cavity to move out of the storage cavity on the fitting plate, adapting to the installation length, and the adjustment is convenient and fast. The length of the rubber tube part of the urinary catheter body remaining outside can be set according to requirements.

[0009] Preferably, in order to prevent the rubber tube part of the urinary catheter body from moving upward and deviating after being installed in the storage cavity, a semicircular arc-shaped storage groove adapted to the rubber tube part of the urinary catheter body is circumferentially opened on the side wall of the groove plate. The arc-shaped storage groove restrains the rubber tube part of the urinary catheter body penetrating into the pipe-passing cavity to prevent it from coming out, and the arc-shaped storage groove is adapted to the cylindrical outer wall of the rubber tube body of the urinary catheter body, and will not affect the flow of the internal liquid.

[0010] Preferably, in order to reduce the wear of the end of the fitting plate on the outer wall of the catheter body, anti-slip rubber plugs are fixedly installed at the positions of the two catheter-passing cavity ends at the end opposite to the knob in the storage cavity. A pressing inlet is provided at the top of the anti-slip rubber plug. By setting the anti-slip rubber plug at the end of the fitting plate and pressing the rubber tube part of the catheter body into it from the upper pressing inlet, it can not only play a role in protecting against wear, but also play a certain fixing role to prevent the catheter body from sliding on the groove plate, making it more stable and reliable.

[0011] Preferably, in order to prevent the strap from sliding down from the thicker position of the thigh to the thinner position of the thigh after being fixed on the leg, a number of anti-slip particles made of rubber and evenly distributed are fixedly installed on the inner side wall of the strap in contact with the human body. By contacting the leg through the anti-slip particles, the strap is prevented from sliding, improving stability.

[0012] Preferably, in order to make the hard iron alloy plate more comfortable when contacting the human body, the fixator further includes a comfortable contact mechanism. The comfortable contact mechanism includes a rubber sleeve sleeved on the bottom of the fitting plate. A honeycomb-shaped gasket is fixedly installed at the bottom of the rubber sleeve. A number of ventilation holes are provided on the gasket. By sleeving the rubber sleeve made of rubber on the bottom of the fitting plate, then attaching one side of the gasket to the leg, and fixing the fitting plate on the leg through the strap, the gasket has a certain elasticity due to the honeycomb structure, making it more comfortable to wear. The ventilation holes provide ventilation when in long-term contact with the skin, reducing the stuffy feeling of the skin.

[0013] When wearing the catheter body, the fitting plate is tied to a suitable position on the patient's leg through the strap. Then, the cover plate is opened, and the rubber tube part of the catheter body remaining outside the human body is bent into a U shape adapted to the groove plate and pressed into the catheter-passing cavity from above, so that the bent part of the rubber tube part of the catheter body fits the groove plate. Then, the length of the stored part is adjusted through the adjusting part, and then the cover plate is covered to cover and protect the rubber tube part of the catheter body. Compared with the existing catheter fixator, it solves the problem that the too long external tube body exposed outside will bring inconvenience to the patient's lying and walking, making the patient wear more comfortably and safely.

[0014] The fixator fixes the fitting plate on the leg through the strap. The gasket has a certain elasticity due to the honeycomb structure, making it more comfortable to wear. The ventilation holes provide ventilation when in long-term contact with the skin, reducing the stuffy feeling of the skin. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Embodiment 1

[0023] This embodiment provides a urinary catheter fixator, as Figures 1-4 shown. The fixator includes a fitting plate 2 for fixing the urinary catheter body 1 on the leg and a binding strap 3 for binding the fitting plate 2 to the leg. A storage and fixing mechanism 4 for protecting the rubber tube part of the urinary catheter body 1 is provided on the fitting plate 2;

[0024] The storage and fixing mechanism 4 includes a storage cavity 41 opened at both ends and penetrating through the outer wall of the fitting plate 2. A groove plate 43 for adjusting the storage length of the rubber tube part of the urinary catheter body 1 and having arc-shaped ends with the top height not higher than the height of the storage cavity 41 is installed in the storage cavity 41 through an adjusting member 42. Two pipe passing cavities 44 with equal widths and adapted to the diameter of the rubber tube part of the urinary catheter body 1 are left between the straight edges of the groove plate 43 and two opposite inner side walls of the fitting plate 2 in the storage cavity 41. The top of the storage cavity 41 is hinged with a cover plate 45.

[0025] When in use, when wearing the urinary catheter body 1, the fitting plate 2 is tied to a suitable position on the patient's leg through the strap 3. Then, the cover plate 45 is opened, and the rubber tube part of the urinary catheter body 1 remaining outside the human body is bent into a U shape matching the groove plate 43 and pressed into the tube-passing cavity 44 from above, so that the bent part of the rubber tube part of the urinary catheter body 1 fits the groove plate 43. Then, the receiving length is adjusted by the adjusting member 42, and then the cover plate 45 is covered to cover and protect the rubber tube part of the urinary catheter body 1. Compared with the existing urinary catheter fixator, it solves the problem that the too-long external tube body exposed outside will bring inconvenience to the patient's lying and walking, making the patient wear more comfortably and safely.

[0026] Specifically, the adjusting member 42 includes a chute 421 opened at the inner bottom of the receiving cavity 41 on the fitting plate 2. A lead screw 422 is movably installed in the chute 421. One end of the lead screw 422 penetrates through the fitting plate 2 and extends outward, and a knob 423 is fixedly installed at the end. A slider 424 that is screwed on the outer side wall of the lead screw 422 in the chute 421 and is adapted to the chute 421 and is fixedly connected to the bottom of the groove plate 43 is provided.

[0027] When in use, by rotating the knob 423, the lead screw 422 is driven to rotate, thereby driving the slider 424 and the groove plate 43 fixed to the slider 424 to move toward one side in the receiving cavity 41, driving the rubber tube part of the urinary catheter body 1 stuck in the tube-passing cavity 44 to contract toward the receiving cavity 41 on the fitting plate 2, so as to receive the too-long rubber tube part of the indwelling urinary catheter body 1 into the receiving cavity 41. Rotating the knob 423 in the other rotation direction drives the lead screw 422 to rotate, thereby driving the slider 424 and the groove plate 43 fixed to the slider 424 to move toward the other side in the receiving cavity 41, driving the rubber tube part of the urinary catheter body 1 stuck in the tube-passing cavity 44 to move toward the outside of the receiving cavity 41 on the fitting plate 2 to adapt to the installation length, and the adjustment is convenient and fast. The length of the rubber tube part of the urinary catheter body 1 remaining outside is set according to requirements.

[0028] Furthermore, an arc-shaped receiving groove 46 in the shape of a semicircle adapted to the rubber tube part of the urinary catheter body 1 is circumferentially opened on the side wall of the groove plate 43. When in use, the rubber tube part of the urinary catheter body 1 inserted into the tube-passing cavity 44 is constrained by the arc-shaped receiving groove 46 to prevent it from coming out, and the arc-shaped receiving groove 46 is adapted to the cylindrical outer wall of the rubber tube body of the urinary catheter body 1 and will not affect the flow of the internal liquid.

[0029] Furthermore, anti-slip rubber plugs 47 are fixedly installed at the positions of the two ends of the through-tube cavities 44 at the end of the storage cavity 41 opposite to the knob 423. A pressing inlet 48 is provided at the top of the anti-slip rubber plug 47. During use, by arranging the anti-slip rubber plugs 47 at the end of the fitting plate 2 and pressing the rubber tube part of the urinary catheter body 1 into it from the pressing inlet 48 above, it can not only play a role in protecting against wear, but also play a certain fixing role to prevent the urinary catheter body 1 from slipping on the groove plate 43, making it more stable and reliable.

[0030] Wherein, a plurality of anti-slip particles 31 made of rubber and evenly distributed are fixedly installed on the inner side wall of the strap 3 in contact with the human body. During use, the strap 3 binds and fixes the fitting plate 2 to the human leg. By contacting the leg through the anti-slip particles 31, the slipping of the strap 3 is prevented, improving stability.

[0031] Embodiment 2

[0032] Different from Embodiment 1, when the rigid fitting plate 2 contacts the human leg, there will be a certain degree of discomfort. Therefore, as Figure 1 、 Figure 2 and Figure 3 shown, the fixator further includes a comfortable contact mechanism 5. The comfortable contact mechanism 5 includes a rubber sleeve 51 sleeved on the bottom of the fitting plate 2. A honeycomb gasket 52 is fixedly installed at the bottom of the rubber sleeve 51. A plurality of ventilation holes 53 are provided on the gasket 52.

[0033] During use, the rubber sleeve 51 made of rubber is sleeved on the bottom of the fitting plate 2, and then one side of the gasket 52 is attached to the leg. The fitting plate 2 is fixed to the leg by the strap 3. Due to the honeycomb structure of the gasket 52, the gasket 52 has a certain elasticity, making it more comfortable to wear. The ventilation holes 53 provide ventilation when in long-term contact with the skin, reducing the stuffy feeling of the skin.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
