Description

Technical Field

[0001] The present invention relates to the technical field of urinary catheter devices, and more particularly to a urinary catheter device for urology. Background Art

[0002] Urinary catheterization refers to inserting a urinary catheter through the urethra into the bladder to drain urine. Urinary catheterization is divided into two types: indwelling catheterization and intermittent catheterization. In the former, the catheter remains indwelling in the patient's body and is removed or replaced regularly when the condition permits. In the latter, catheterization is performed every - hour, and the catheter is removed after the bladder is emptied. The urinary catheter should not be reused, otherwise the user may be infected with bacteria.

[0003] Deficiencies of the prior art: During the use of the urinary catheter device, it is necessary to drain the urine in the urine bag body according to the urine output of the patient. Usually, it needs to be drained multiple times a day. Generally, the drainage tube of the urine bag is opened, and then the urine in the urine bag body flows out naturally. The urination efficiency is slow and the urination is incomplete. For this reason, we have proposed a urinary catheter device for urology. Summary of the Invention

[0012] Preferably, a fitting soft pad and an elastic band are installed at the rear end of the housing. Mutually cooperating magic tapes are respectively installed on the surface of the elastic band.

[0013] The technical effects and advantages of the present invention:

[0014] 1. By controlling the downward movement of the slider, the slider will drive the rotating rod and the extrusion roller to move downward. At the same time, under the action of the first guiding groove, the rotating rod and the extrusion roller will gradually move closer to the center position during the downward movement. Under the action of the extrusion roller, the urine bag body is extruded from above, thereby promoting the urine in the urine bag body to enter the output connector through the output pipe. When the urine bag body is extruded, finally, it is discharged through the discharge pipe inserted at the lower end of the output connector. Repeating the up and down sliding of the slider twice can not only fully discharge the urine in the urine bag body, but also improve the urine discharge speed, without waiting for the urine to be automatically discharged under the action of gravity. In the case of using the urine bag body to discharge urine multiple times a day, the use experience of the patient is improved.

[0015] 2. Under the action of the sliding rod and the second guide groove in the present invention, when the slider moves downward, the sliding rod installed in the slider will slide in the second guide groove at this time, and the second sliding rod will drive the connecting block to slide on the circumferential surface of the guide shaft, thereby driving the driving frame to move to both sides. At this time, the position restriction on the push rod is released, and the tension spring can pull the first plug block to move to both sides, so as to achieve the effect of opening the output discharge head to quickly discharge urine when squeezing the urine bag body. At the same time, when the slider and the extrusion roller rise and reset, the connecting block and the driving frame can be driven to move inward at the same time. The push rod is pushed by the driving frame to drive the first plug block to merge and block the output connection head. After the urine discharge is completed, the output connection head is automatically blocked.

[0016] 3. When the input tube is slowly pulled out from the input connection head to replace the urine bag body in the present invention, at this time, under the action of the third spring, the third spring will push the second plug block to move inward and merge together. When the input tube is not completely pulled out from the input connection head, the second plug block will block the input connection head to prevent urine from leaking from the input connection head when replacing the urine bag body.

Detailed implementation manners

[0034] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. A urinary catheterization device for urology involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] As Figure 1-13As shown, in one embodiment, a urinary catheterization device for urology is proposed, which includes a housing 1. A positioning rod 101 is arranged inside the housing 1. A urine bag body 102 is installed on the circumferential surface of the positioning rod 101 through a loop. An input connector 103 and an output connector 104 are installed inside the housing 1. The urine bag body 102 is connected to the input connector 103 through an input tube 105, and the urine bag body 102 is connected to the output connector 104 through an output tube 106. The input connector 103 is connected to a urinary catheter 107 through a connecting tube. A squeezing assembly 2 is arranged inside the housing 1. The squeezing assembly 2 includes a mounting plate 201, a first guiding groove 202, a rotating rod 203 and a squeezing roller 204. A pair of mounting plates 201 are both installed inside the housing 1. A pair of first guiding grooves 202 are both opened on the surface of the mounting plate 201. A pair of rotating rods 203 are both slidably connected in the first guiding grooves 202. The squeezing rollers 204 are both rotatably connected to the circumferential surface of the rotating rod 203. A slider 205 is slidably connected inside the housing 1. An activity groove 206 is opened inside the slider 205. Both ends of the rotating rod 203 are located inside the activity groove 206.

[0036] In the actual application of the embodiment of the present invention, the disinfected urinary catheter 107 is inserted into the patient's bladder, and then the urinary catheter 107 is connected to the input connector 103 through a connecting tube. When urine is produced in the patient's bladder, the urine will enter the input connector 103 under the action of the urinary catheter 107 and the connecting tube, and then enter the urine bag body 102 through the input tube 105 for collection and storage. When there is more urine stored in the urine bag body 102, at this time, by controlling the slider 205 to move downward, the slider 205 will drive the rotating rod 203 and the squeezing roller 204 to move downward. At the same time, under the action of the first guiding groove 202, the rotating rod 203 and the squeezing roller 204 will gradually move closer to the center position during the downward movement. At the same time, the rotating rod 203 will slide inward in the activity groove 206. Under the action of the squeezing roller 204, the urine bag body 102 is squeezed from above, thereby promoting the urine in the urine bag body 102 to enter the output connector 104 through the output tube 106. When squeezing the urine bag body 102, under the action of the positioning rod 101 and the loop, the urine bag body 102 is suspended inside the housing 1, and at the same time the position of the urine bag body 102 is fixed to prevent the urine bag body 102 from moving downward when being squeezed. Finally, the urine is discharged through the discharge tube inserted at the lower end of the output connector 104. Repeating the up and down sliding of the slider 205 twice can not only fully discharge the urine in the urine bag body 102, but also improve the urine discharge speed without waiting for the urine to be automatically discharged under the action of gravity. In the case of using the urine bag body 102 to discharge urine multiple times a day, the use experience of the patient is improved.

[0037] In a case of an embodiment of the present invention, since the surface of the extrusion roller 204 is made of rubber material, due to its own material, it has a high friction force with the urine bag body 102. At the same time, the extrusion roller 204 is rotatably connected to the rotating rod 203. When pressing down the urine bag body 102, when the extrusion roller 204 is in the descending position, it rotates on the surface of the urine bag body 102 and can smoothly move from top to bottom, squeezing the urine bag body 102 to promote the discharge of urine.

[0038] As Figure 11 and 15 shown, as a preferred embodiment of the present invention, a closing mechanism 3 is provided in the output connector 104. The closing mechanism 3 includes a first plug 301, a tension spring 302 and a push rod 303. A pair of first plugs 301 are slidably connected in the output connector 104. The tension spring 302 is installed between the first plug 301 and the output connector 104. The push rod 303 is slidably connected in the output connector 104 and is fixedly connected to the first plug 301.

[0039] In the actual application of the embodiment of the present invention, when the position of the push rod 303 is restricted, the two first plugs 301 can be in a fitting state, thereby achieving the effect of blocking the output connector 104 and avoiding the leakage of urine. When the restriction on the position of the push rod 303 is released, at this time, under the action of the tension spring 302, the tension spring 302 will pull the first plugs 301 to move to both sides, thereby opening the output connector 104 and achieving the effect of discharging urine subsequently.

[0040] As Figure 9-12 shown, as another preferred embodiment of the present invention, two groups of guide shafts 304 are installed in the housing 1. The circumferential surfaces of each group of guide shafts 304 are slidably connected with connection blocks 305. Second guide grooves 306 are formed in the connection blocks 305. A slide rod 307 is installed between the sliders 205. The slide rod 307 is slidably connected with the second guide grooves 306. The driving frame 308 installed at the lower end of the connection block 305 is slidably connected with the mounting plate 201. The driving frame 308 is in contact with the push rod 303.

[0041] In the actual application of the embodiment of the present invention, when the slider 205 moves downward, driving the extrusion roller 204 to move downward to extrude the urine bag body 102 to discharge urine, at this time, the slide bar 307 installed in the slider 205 will slide in the second guide groove 306. Subsequently, under the action of the second guide groove 306, the second slide bar 307 will drive the connecting block 305 to slide on the circumferential surface of the guide shaft 304, causing the connecting block 305 to move to both sides, and further driving the driving frame 308 to move to both sides. Since the driving frame 308 and the push rod 303 were originally in a fitting state, when the driving frame 308 moves to both sides, the position restriction on the push rod 303 is released at this time. Subsequently, under the action of the tension spring 302, the first blocking block 301 can be pulled to move to both sides, so as to achieve the effect of synchronously opening the output discharge head when extruding the urine bag body 102 to realize rapid urine discharge. At the same time, when the slider 205 and the extrusion roller 204 rise and reset, under the action of the slide bar 307 and the second guide groove 306, the connecting block 305 and the driving frame 308 can be driven to move inward at the same time. The driving frame 308 pushes the push rod 303 to move, so that the first blocking block 301 is combined to block the output connection head 104. After the urine discharge is completed, when the extrusion roller 204 rises and resets, the output connection head 104 automatically closes.

[0042] As Figure 10 shown, as another preferred embodiment of the present invention, a pressing plate 4 is rotatably connected inside the slider 205. A first spring 401 is installed between the pressing plate 4 and the slider 205. A buckle 402 is provided on the surface of the pressing plate 4, and a clamping groove 403 is formed on the surface of the housing 1. The buckle 402 is located in the clamping groove 403.

[0043] In the actual application of the embodiment of the present invention, when pressing down to push the slider 205, the pressing plate 4 will be contacted first. Since the force generated when pushing the slider 205 downward is downward, the pressing plate 4 will rotate at this time, causing the buckle 402 to disengage from the clamping groove 403. Subsequently, the slider 205 can move downward to achieve the effect of promoting urine discharge. When the urine discharge is completed, at this time, push the slider 205 to reset upward. When the slider 205 is reset, at this time, under the action of the first spring 401, the first spring 401 will push the pressing plate 4 to rotate, so that the buckle 402 installed on the surface of the pressing plate 4 re-enters the clamping groove 403, achieving the effect of fixing the position of the slider 205 when it is reset.

[0044] As Figure 6 and 7 shown, as another preferred embodiment of the present invention, a shell door 108 is rotatably connected inside the housing 1. A clamping block 109 is slidably connected inside the shell door 108. A second spring 1010 is installed between the clamping block 109 and the shell door 108. A groove 1011 is formed inside the housing 1. The clamping block 109 is located in the groove 1011.

[0045] In practical applications of the embodiments of the present invention, by arranging the urine bag body 102 inside the housing 1, the urine bag body 102 can be protected from being squeezed by the outside world, preventing the urine bag body 102 from being damaged or the urine in the urine bag body 102 from flowing back into the bladder. When it is necessary to replace the urine bag body 102, by pushing the latch 109 upward, the latch 109 will be pulled out from the groove 1011, and then the housing door 108 is rotated, and subsequently, the urine bag body 102 in the housing 1 can be replaced.

[0046] As Figure 12 and 15 shown, as another preferred embodiment of the present invention, a leak-proof mechanism 5 is arranged inside the input connector 103. The leak-proof mechanism 5 includes a second plug 501, a third spring 502, and a tapered surface 503. A pair of second plugs 501 are both slidably connected inside the input connector 103. The third spring 502 is installed between the second plug 501 and the input connector 103. The tapered surface 503 is formed at the lower end of the second plug 501.

[0047] In practical applications of the embodiments of the present invention, since the urine bag body 102 is a consumable item, it needs to be replaced when it reaches the service life. When replacing the urine bag body 102, the input tube 105 on the urine bag body 102 is pulled out from the input connector 103, and the output tube 106 is pulled out from the output connector 104. When the input tube 105 is slowly pulled out from the input connector 103, under the action of the third spring 502, the third spring 502 will push the second plugs 501 to move inward and merge together. Before the input tube 105 is completely pulled out from the input connector 103, the second plugs 501 will block the input connector 103 to prevent urine from leaking from the input connector 103. Subsequently, a new urine bag body 102 can be replaced. The input tube 105 and the output tube 106 on the urine bag body 102 are respectively inserted into the input connector 103 and the output connector 104. When the input tube 105 is inserted into the input connector 103, under the action of the tapered surface 503, the second plugs 501 can be pushed to both sides to open them, and then the input tube 105 can completely enter the input connector 103 to complete the installation and replacement of the urine bag body 102.

[0048] As Figure 11 and 12 shown, as another preferred embodiment of the present invention, both the input connector 103 and the output connector 104 are made of magnetic materials, and a pair of magnetic blocks 1012 are installed inside the housing 1. The input connector 103 and the output connector 104 are both adsorbed and fixed inside the housing 1 by the magnetic blocks 1012.

[0049] In practical applications of the embodiments of the present invention, both the input connector 103 and the output connector 104 are made of magnetic adsorption material and are adsorbed and fixed in the housing 1 by the magnetic block 1012. When replacing the urine bag body 102 or the catheter 107, it is convenient to disassemble the input connector 103 and the output connector 104, facilitating cleaning and disinfection thereof, and avoiding the growth of bacteria therein.

[0050] As Figure 1 and 5 shown, as another preferred embodiment of the present invention, a fitting soft pad 1013 and an elastic band 1014 are installed at the rear end of the housing 1, and mutually cooperating magic tapes 1015 are respectively installed on the surface of the elastic band 1014.

[0051] In practical applications of the embodiments of the present invention, under the action of the fitting soft pad 1013, the elastic band 1014 and the magic tape 1015, when the patient walks and moves, the housing 1 is fixed to the patient's body, and through the action of the housing 1, it can effectively prevent the urine bag body 102 from contacting external objects, achieving the effect of protecting the urine bag body 102.

[0052] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent relative position relationships.

[0053] Second: In the drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0054] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
