Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of urology nursing devices, in particular to a urinary catheter. Background Art
[0002] A urinary catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted through the urethra into the bladder to drain urine.
[0003] The existing process of using a urinary catheter is as follows: the medical staff inserts the tip of the urinary catheter into the bladder along the urethra and prostate, and then inflates the airbag at the tip of the urinary catheter so that the airbag expands and gets stuck in the bladder to prevent the tip of the urinary catheter from falling out of the bladder. The tail end of the urinary catheter is then connected to the urine collection bag through a connecting tube, and the urinary catheter, the connecting tube and the urine collection bag are fixed on the patient's thigh. The urine is sucked into the urinary catheter through the urinary catheter port at the tip of the urinary catheter, and then the urine is poured into the urine collection bag through the connecting tube. This completes a workflow, and the urinary catheter can be replaced after a few days. It should be noted that during the insertion of the urinary catheter into the bladder, the patient may perform activities such as standing, lying, sitting, and walking. When the patient is active, the airbag and the tip of the urinary catheter may easily shake, and urine is difficult to stably flow out of the urinary catheter port, resulting in insufficient stability during catheterization. In addition, when the patient moves, his thighs and hips will also move, which can easily pull on the connecting tube and make it loose, and then easily cause the connection between the connecting tube and the urinary catheter and urine collection bag to loosen, thus causing urine leakage.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A urinary catheter, comprising:
[0007] An insertion tube, wherein the head end of the insertion tube is provided with a tube head, and the outer wall of the insertion tube is provided with a urinary catheter, a first air bag, and a second air bag in sequence in a direction gradually away from the tube head, a gap is reserved between the first air bag and the second air bag, the first air bag is connected to one end of a first connecting tube, and the other end of the first connecting tube is connected to the outside, the second air bag is connected to one end of a second connecting tube, and the other end of the second connecting tube is connected to the outside;

[0013] Preferably, the transition pipe is threadedly connected to an opening of the urine collecting device.
[0014] Preferably, one end surface of the placement groove is a fixed panel, and the other end surface opposite to the placement groove is a cover body.
[0015] Preferably, a limiting groove is concavely provided on the arc-shaped inner side wall of the placement groove, and a limiting block is provided on the outer side wall of the urine collecting device, and the limiting block and the limiting groove extend to the cover body.
[0016] Preferably, the first airbag and the second airbag are arranged to surround the outer side wall of the insertion tube.
[0017] Preferably, one end of the first connecting tube and the second connecting tube is arranged in the insertion tube, and passes through the side wall of the insertion tube to be connected with the first airbag and the second airbag respectively, and the other end of the first connecting tube and the second connecting tube passes through a position close to the rear end of the insertion tube to be connected with the outside.
[0018] Preferably, the fixing device is a bandage.
[0019] Preferably, a penetrating fixing channel is provided on one side of the roll, and the bandage passes through the fixing channel to fix the roll on the leg.
[0020] Compared with the prior art, the beneficial effect of the utility model is that in the initial state, the first airbag and the second airbag are in a contracted state. The medical staff inserts the insertion tube into the urethra, the prostate area, and the bladder area in sequence, and the tube head, the urinary catheter port and the first airbag are located in the bladder area, and the second airbag is located in the prostate area. The medical staff inflates the first airbag through the first connecting tube, and the first airbag expands to support the lower side of the bladder area. The medical staff inflates the second airbag through the second connecting tube, and the second airbag expands to support the upper side of the prostate area. The first airbag and the second airbag respectively support the bladder area and the prostate area to prevent the insertion tube and the urinary catheter port from shaking.

When the patient presses his legs downward, the distance between the reel and the insertion tube becomes larger, and the extension tube drives the reel to rotate counterclockwise, so that the portion of the extension tube extending out of the reel becomes longer. In other words, through the adjustment of the reel, the portion of the extension tube extending out of the reel is always at a length that is just connected to the insertion tube. The extension tube and the urine collecting device will not be too tightly connected due to the extended portion of the extension tube being too short, thereby causing the connection to be easily loosened. The extension tube will not be easily pulled due to the extended portion of the extension tube being too long, thereby causing the connection between the extension tube and the urine collecting device to be easily loosened. The stability of the connection between the extension tube and the urine collecting device is ensured, and the problem of urine easily leaking from the connection of the urine collecting device is solved.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Example 1
[0030] For easier understanding, see Figure 1-Figure 5 This embodiment provides a urinary catheter, including: an insertion tube 3, an extension tube 17, a reel 7, and a urine collecting device 8.
[0031] like Figure 1-Figure 3 As shown, the insertion tube 3 is used to be inserted into the bladder area 6 along the urethra and prostate area 4. The head end of the insertion tube 3 is the insertion end, and a tube head 5 is provided at the head end of the insertion tube 3, and the tube head 5 is conical. Figure 2 and Figure 3As shown, the outer wall of the insertion tube 3 is provided with a urinary catheter port 9 close to the tube head 5, a first airbag 10 is provided at the lower end of the urinary catheter port 9, a second airbag 11 is provided at the lower end of the first airbag 10, and a gap is reserved between the first airbag 10 and the second airbag 11. The urinary catheter is also provided with a first connecting tube 12 and a second connecting tube 13, one end of the first connecting tube 12 is connected to the first airbag 10, the other end of the first connecting tube 12 is connected to the outside of the insertion tube 3, one end of the second connecting tube 13 is connected to the second airbag 11, and the other end of the second connecting tube 13 is connected to the outside of the insertion tube 3. The first airbag 10 can be inflated or deflated through the first connecting tube 12 to control the expansion and contraction of the first airbag 10, and the second airbag 11 can be inflated or deflated through the second connecting tube 13 to control the expansion and contraction of the second airbag 11.
[0032] The head end of the extension tube 17 is communicated with the tail end of the insertion tube 3 .
[0033] The reel 7 is specifically a spring-type reel. When in use, the medical staff fixes the reel 7 on the leg 1 of the human body through the fixing device 2. The axial direction of the reel 7 is horizontally set, and the reel 7 can rotate along the axial direction. The tail end of the extension tube 17 is wrapped around the reel 7 for several turns.
[0034] The urine collecting device 8 is detachably arranged on the reel 7, and when the reel 7 rotates, the urine collecting device 8 is driven to rotate together. The tail end of the extension tube 17 is detachably connected to the urine collecting device 8.
[0035] The method of using the urinary catheter provided in this embodiment is as follows: In the initial state, the first airbag 10 and the second airbag 11 are in a contracted state. The medical staff inserts the insertion tube 3 into the urethra, the prostate area 4, and the bladder area 6 in sequence. Figure 2 As shown, the tube head 5, the urinary catheter port 9 and the first airbag 10 are located in the bladder area 6, and the second airbag 11 is located in the prostate area 4. The medical staff inflates the first airbag 10 through the first connecting tube 12, and the first airbag 10 expands to press against the lower side of the bladder area 6. The medical staff inflates the second airbag 11 through the second connecting tube 13, and the second airbag 11 expands to press against the upper side of the prostate area 4. The first airbag 10 and the second airbag 11 respectively press against the bladder area 6 and the prostate area 4 to prevent the insertion tube 3 and the urinary catheter port 9 from shaking. Even when the patient moves, it is not easy to cause the urinary catheter port 9 to shake, thereby avoiding the problem of insufficient catheterization stability caused by the shaking of the urinary catheter port 9. At this time, urine can be introduced into the urine collecting device 8 along the insertion tube 3 and the extension tube 17 through the urinary catheter port 9. In addition, as Figure 1As shown, the medical staff wraps the portion of the extension tube 17 near the tail end around the reel 7. When the patient lifts his leg 1 upward, the distance between the reel 7 and the insertion tube 3 becomes smaller, and the reel 7 rotates clockwise under the action of the spring. When the patient presses down on the leg 1, the distance between the reel 7 and the insertion tube 3 becomes larger, and the extension tube 17 drives the reel 7 to rotate counterclockwise, so that the portion of the extension tube 17 extending out of the reel 7 becomes longer. In other words, through the adjustment of the reel 7, the portion of the extension tube 17 extending out of the reel 7 is always at a length that is just connected to the insertion tube 3. The extension tube 17 and the urine collecting device 8 will not be too tightly connected due to the extended portion of the extension tube 17 being too short, thereby causing the connection to be easily loosened. The extension tube 17 will not be easily pulled due to the extended portion of the extension tube 17 being too long, thereby causing the connection between the extension tube 17 and the urine collecting device 8 to be easily loosened. The stability of the connection between the extension tube 17 and the urine collecting device 8 is ensured, and the problem of urine easily leaking from the connection of the urine collecting device 8 is solved.
[0036] In one embodiment, the main body of the reel 7 is cylindrical, and the extension tube 17 is wound around the circumferential side wall of the reel 7. A cylindrical placement groove is provided in the axial center area of the reel 7, and the urine collecting device 8 is cylindrical in shape. The urine collecting device 8 is embedded in the placement groove, and the urine collecting device 8 is in clearance fit with the placement groove. Figure 5 As shown, a through hole connecting the placement groove and the outside is provided on the circumferential side wall of the reel 7, and the opening at the connection point between the urine collecting device 8 and the extension tube 17 is aligned with the through hole. One end of a transition tube 14 is threadedly connected to the opening of the urine collecting device 8, and the other end of the transition tube 14 passes through the through hole and is connected to the tail end of the extension tube 17. One end face of the placement groove is a fixed panel, and the other end face opposite to the placement groove is a cover body. A limiting groove 16 is recessed on the arc-shaped inner side wall of the placement groove, and a limiting block 15 is provided on the outer side wall of the urine collecting device 8, and the limiting block 15 and the limiting groove 16 extend to the cover body.
[0037] The urinary catheter of this embodiment can be used in the following manner: open the cover, align the limit block 15 of the urine collecting device 8 with the limit groove 16, push the urine collecting device 8 inward to the deepest point along the direction of the limit groove 16, then close the cover, pass the transition tube 14 through the through hole to connect with the urine collecting device 8, and connect the other end of the transition tube 14 with the extension tube 17. The urinary catheter of this embodiment can be used after completing the above operations. It should be noted that the setting of the limit block 15 and the limit groove 16 can prevent the urine collecting device 8 from being displaced with the reel 7 when rotating with the reel 7, causing the connection between the transition tube 14 and the urine collecting device 8 to loosen. The setting of the cover can prevent the urine collecting device 8 from falling from the placement slot. The transition tube 14 is provided to detachably connect the extension tube 17 and the urine collecting device 8, so as to facilitate the removal and placement of the urine collecting device 8 from the placement slot.
[0038] In one embodiment, the first airbag 10 and the second airbag 11 are arranged to surround the outer side wall of the insertion tube 3. When the first airbag 10 and the second airbag 11 are inflated, they are in a circular ring shape, which can more stably support the bladder area 6 and the prostate area 4, and can better fix the insertion tube 3 to prevent the insertion tube 3 from shifting. One end of the first connecting tube 12 and the second connecting tube 13 is arranged in the insertion tube 3, and passes through the side wall of the insertion tube 3 to communicate with the first airbag 10 and the second airbag 11 respectively, and the other end of the first connecting tube 12 and the second connecting tube 13 passes through a position close to the tail end of the insertion tube 3 and communicates with the outside. The length of the first connecting tube 12 and the second connecting tube 13 is similar to that of the insertion tube 3, and will not be too long, and will not affect the patient's activities.
[0039] In one embodiment, the fixing device 2 is a bandage. A fixing channel is provided on one side of the reel 7, and the bandage passes through the fixing channel and is wrapped around the leg 1 of the human body, so as to fix the reel 7 on the leg 1, prevent the reel 7 from shaking, and facilitate the removal of the reel 7.
[0040] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
