Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a urinary catheter. Background Art

[0002] A urinary catheter is a medical device that can be inserted into the bladder through the urethra to drain urine. The head of the catheter is provided with a urinary outlet connected to the interior of the catheter so that urine can flow into the interior of the catheter through the urinary outlet.

[0003] To ensure patient comfort, the catheter must be made of flexible materials. Furthermore, the provision of a urination port reduces the structural strength of the catheter head. If the structural strength is too low, the catheter head will easily bend, thereby affecting urination. Therefore, the urination port in the prior art is generally set relatively small to reduce the negative impact of the structural strength of the catheter head and avoid bending of the catheter head as much as possible, but this also results in a slower urination speed. Utility Model Content

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0032] The present invention provides a urinary catheter 1000, such as Figure 1-Figure 5 As shown, the urinary catheter 1000 includes a tube body 100 and a reinforcing rib 200. The tube body 100 includes a head 110 and a tail 120 arranged opposite to each other in the longitudinal direction. A urination opening 112 is provided on the outer peripheral wall 111 of the head 110. The urination opening 112 is connected to the internal space of the tube body 100. The reinforcing rib 200 is arranged on the head 110 along the longitudinal direction of the urinary catheter 1000.

[0033] Specifically, since the catheter 1000 of the present invention is additionally provided with a reinforcing rib 200, the reinforcing rib 200 is arranged at the head 110 of the tube body 100 along the length direction of the catheter 1000, so the reinforcing rib 200 can provide support for the head 110 of the tube body 100 to ensure that the head 110 of the tube body 100 will not bend.

[0034] Firstly, the presence of the reinforcing rib 200 can prevent the bending of the head 110 of the tube body 100 from affecting urination.

[0035] Secondly, because the reinforcing ribs 200 prevent the head 110 of the tube 100 from bending, the urination opening 112 can be designed to be larger than in the prior art, which helps speed up urination. Furthermore, the larger urination opening 112 can also reduce the probability of blood clot blockage. This is because the larger urination opening 112 will increase the number of blood clots smaller than the caliber of the urination opening 112, making the urination opening 112 more capable of discharging blood clots, thereby reducing the probability of blood clot blockage.

[0036] It should be noted that the reason why the reinforcing rib 200 is provided at the head 110 instead of providing a reinforcing rib 200 passing through the tube body 100 is because the reinforcing rib 200 passing through the tube body 100 will cause the catheter 1000 to be relatively hard, which will reduce the patient's comfort. Therefore, the reinforcing rib 200 of the present application is provided at the head 110 of the tube body 100.

[0037] It is worth mentioning that there are many materials suitable for making the reinforcing rib 200, such as titanium, chromium-titanium alloy, spring steel, nickel-titanium alloy, etc., so this embodiment does not limit this.

[0038] In a specific embodiment, there are two reinforcing ribs 200, which are symmetrically arranged on both sides of the head 110. This can provide stronger support for the head 110 of the tube body 100, so that the urination opening 112 can be designed to be larger, which is conducive to accelerating urination.

[0039] refer to Figure 1-Figure 5 In some embodiments, the reinforcing rib 200 is disposed on the inner side of the outer peripheral wall 111 of the head 110 .

[0040] Specifically, if the reinforcing rib 200 protrudes from the outer peripheral wall 111 of the head 110, the shape of the catheter 1000 will be unfavorable for the tube body 100 to be inserted into the patient's body. Therefore, in this embodiment, the reinforcing rib 200 is set on the inner side of the outer peripheral wall 111 to prevent the reinforcing rib 200 from affecting the insertion of the tube body 100 into the patient's body.

[0041] refer to Figure 4 、 Figure 5 In a specific embodiment, the head portion 110 includes an end wall 113 disposed away from the tail portion 120 . The end wall 113 is provided with a mounting hole 114 , and the reinforcing rib 200 is installed into the head portion 110 via the mounting hole 114 .

[0042] Specifically, providing a mounting hole 114 in the tail portion 120 for the reinforcing rib 200 to pass through the tube body 100 and then continuously moving the reinforcing rib 200 from the tail portion 120 to the head portion 110 is also a feasible solution. However, this would make assembly of the reinforcing rib 200 more difficult and time-consuming. To reduce assembly difficulty and time, this embodiment provides a mounting hole 114 on the end wall 113 of the head portion 110, which is away from the tail portion 120. Once the reinforcing rib 200 is inserted into the mounting hole 114, the reinforcing rib 200 is immediately installed, thereby reducing assembly difficulty and time.

[0043] refer to Figure 2 In a specific embodiment, the urinary catheter 1000 further includes a cap 300, which is disposed on the end wall 113 to cover the mounting hole 114. This arrangement can prevent the reinforcing rib 200 from contacting the external environment and protect the reinforcing rib 200 from contamination.

[0044] refer to Figure 2 In a specific embodiment, a surface of the cap body 300 away from the tail portion 120 is an arc-shaped surface 310 .

[0045] Specifically, if the side of the cap body 300 away from the tail portion 120 is flat, the edge position will be relatively sharp. When the tube body 100 penetrates the patient's body, the sharp edge will easily scratch the urethra. To solve this technical problem, the present application sets the side of the cap body 300 away from the tail portion 120 as a curved surface 310. In this way, the cap body 300 does not have a sharp edge that is easy to scratch the urethra, thereby preventing the cap body 300 from scratching the user's urethra when the tube body 100 penetrates the patient's body.

[0046] refer to Figure 2 In some embodiments, a through hole 320 is provided on a side of the cap body 300 away from the tail portion 120 , and the through hole 320 is connected to the internal space of the tube body 100 .

[0047] Specifically, when inserting the urinary catheter 1000, a blood clot may block the urethra, preventing further insertion of the catheter. In this case, the urethra needs to be unblocked. In this embodiment, a through hole 320 is provided on the side of the cap 300 away from the tail 120. The through hole 320 communicates with the interior space of the tube body 100. This arrangement allows medical personnel to insert a guide wire or other unblocking tool into the tube body 100 and pass the guide wire through the through hole 320 to the blocked area, thereby breaking up the blood clot and unblocking the urethra.

[0048] refer to Figure 2 In a specific embodiment, a chamfer 321 is provided at the opening of the through hole 320 facing away from the tail portion 120. With this arrangement, there are no sharp edges at the opening of the through hole 320 facing away from the tail portion 120, which can effectively prevent the tube body 100 from scratching the urethra when it penetrates the patient's body.

[0049] In some embodiments, the urination opening 112 is a waist-shaped hole disposed along the length of the tube 100. Compared to rectangular holes, waist-shaped holes can more effectively reduce water flow resistance, allowing water to pass through more quickly. Therefore, this embodiment employs a waist-shaped hole to increase urination speed.

[0050] With the support of the reinforcing rib 200, the length of the waist-shaped hole in this embodiment can be configured to be greater than or equal to 1.4 cm and less than or equal to 1.6 cm, which is three times longer than the existing technology; the width can be configured to be greater than or equal to 2.5 mm and less than or equal to 3.5 mm, which is one and a half times wider than the existing technology.

[0051] In some embodiments, two urination openings 112 are provided, and the two urination openings 112 are oppositely disposed on two sides of the head 110 .

[0052] Specifically, the urination speed can be increased by increasing the number of urination openings 112. It is worth mentioning that, due to the presence of the reinforcing ribs 200, the head 110 of the tube 100 is still not easy to bend after the urination openings 112 are added.

[0053] refer to Figure 2 、 Figure 6 、 Figure 7 In some embodiments, a recessed portion 1111 is further provided on the outer peripheral wall 111 of the head portion 110 , and a flushing channel 130 is provided on the tail portion 120 , and the flushing channel 130 is connected to the recessed portion 1111 .

[0054] Specifically, when flushing liquid is injected into the flushing channel 130, the flushing liquid can be sprayed out from the recessed portion 1111, and the flushing liquid can flush the blood stains in the urethra, so that the blood stains can be discharged from the patient's body through the tube body 100. The purpose of providing the recessed portion 1111 is to separate the flushing channel 130 from the patient's skin, which is conducive to the discharge of the flushing liquid and the flushing of the blood stains.

[0055] like Figure 5 As shown, when there is only one reinforcing rib 200, the recessed portion 1111 can be provided on opposite sides of the head portion 110 from the reinforcing rib 200. When there are two reinforcing ribs 200, and the two reinforcing ribs 200 are symmetrically provided on both sides of the head portion 110, the recessed portion 1111 can be staggered with the reinforcing rib 200 in the circumferential direction of the head portion 110, or one of the reinforcing ribs 200 can be provided on the side of the recessed portion 1111 close to the interior space of the tube body 100.

[0056] refer to Figure 2 In a specific embodiment, the recessed portion 1111 is an arc-shaped recessed portion 1111, so that the edge of the recessed portion 1111 adjacent to the outer peripheral wall 111 of the head 110 is not very sharp.

[0057] refer to Figure 2 、 Figure 6 、 Figure 7 In some embodiments, the urinary catheter 1000 further includes an airbag 400 , which is disposed on the head 110 and located on a side of the urination opening 112 close to the tail 120 . The tail 120 is provided with an air supply channel 140 communicating with the airbag 400 .

[0058] Specifically, after the tube body 100 is inserted into place, gas is injected into the air supply channel 140 to expand the airbag 400. The airbag 400 can be stuck in the urethra to prevent the tube body 100 from retreating from the urethra.

[0059] refer to Figure 1 In some embodiments, the tail portion 120 of the catheter 1000 is provided with a joint structure 500 , which includes a first joint 510 , which is connected to the internal space of the tube body 100 so that urine can flow out of the tube body 100 through the first joint 510 .

[0060] refer to Figure 1 In a specific embodiment, the joint structure 500 includes a second joint 520, which is connected to the gas supply channel 140. The second joint 520 is used to connect to an external gas source so that the gas source can fill the gas supply channel 140 with gas through the second joint 520.

[0061] refer to Figure 1 In a specific embodiment, the joint structure 500 includes a third joint 530, which is connected to the flushing channel 130. The third joint 530 is used to connect to a flushing device that provides flushing liquid from the outside, so that the flushing liquid can enter the flushing channel 130 through the third joint 530.

[0062] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
