[0002] A urinary catheter is used to assist or control the flow of urine from the patient's bladder. When a patient needs to use a urinary catheter, the catheter needs to be inserted from the urethra. The balloon of the balloon-type urinary catheter currently on the market is thicker than the catheter body, which causes pain to the patient whether inserting or removing it, especially when removing it, because the balloon is inflated for a long time and will produce horizontal wrinkles when it shrinks, which makes the patient more painful. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of urinary catheter, aiming to overcome the defects of the prior art and solve the problem that the balloon part of the urinary catheter is thicker than the tube body, causing pain to the patient whether inserting or removing it.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] like Figure 1 to Figure 7 As shown, the novel urinary catheter of the present invention comprises a tube body 9, a balloon 6 and an extended plug 1; the extended plug 1 comprises a head and a balloon adhesive portion 2, the rear end of the balloon adhesive portion 2 is connected to the tube body 9, and the balloon 6 is installed outside the balloon adhesive portion 2 and is sealed. The extended plug 1 preferably adopts an extended integrated structure design, or the head and the balloon adhesive portion 2 can be processed independently and then bonded into one.

[0017] The tube body 9 is provided with a countersunk hole 11 with the same diameter as the connecting part of the elongated plug 1, and the elongated plug 1 is plugged into the countersunk hole of the tube body 9 and glued. The diameter of the balloon adhesive portion 2 is smaller than the diameter of the head of the elongated plug 1, so that the outer circumferential diameter of the balloon 6 contracted into a cylindrical shape is smaller than or equal to the diameter of the head of the elongated plug 1, and is equal to or close to the diameter of the tube body, so as to avoid the balloon protruding from the elongated plug and causing large-area friction with the urethra, thereby reducing the pain caused to the patient.

[0018] Specifically, a drainage port 3 is provided on the side of the head of the extended plug 1, and a drainage channel 12 connected to the drainage port 3 is provided at the center of the corresponding balloon adhesive portion 2. Similarly, a drainage channel 12 is also provided on the tube body 9, and the two sections of the drainage channel 12 remain connected.

[0019] A flushing port is provided on the head end face of the extended plug 1, and a flushing channel 13 connected to the flushing port 4 is provided on the corresponding balloon adhesive portion 2. Similarly, a flushing channel 13 is also provided on the tube body 9, and the two sections of the flushing channels 13 are kept connected through a tubular flushing port connector 8. At the same time, adding the flushing port connector 8 can avoid pipeline blockage caused by the falling of the inner wall coating of the flushing channel 13.

[0020] Similarly, a water injection port 5 is provided on the side wall of the balloon adhesive portion 2 at a position opposite to the balloon 6, and a water injection channel 14 connected to the water injection port 5 is provided on the tube wall of the balloon adhesive portion 2. Similarly, a water injection channel 14 is also provided on the tube body 9, and the two sections of the water injection channel 14 are kept connected by a tubular water injection port connector 7. At the same time, adding the water injection port connector 7 can avoid pipeline blockage caused by the falling of the inner wall coating of the water injection channel 14.

[0021] Among them, the water injection port connector 7 and the flushing port connector 8 can be added or not according to needs; if the tube body 9 is relatively thin and it is necessary to increase the strength and toughness of the tube body, the water injection port connector 7 and the flushing port connector 8 are added; if the tube body 9 is relatively thick and has sufficient strength and toughness, there is no need to add the water injection port connector 7 and the flushing port connector 8, and the same circulation effect can be achieved without blockage caused by the falling of the coating on the inner wall of the pipeline.

[0022] In addition, the balloon 6 in the contracted state is cylindrical in shape, and a plurality of elastic silicone reinforcing ribs 10 are arranged on the inner wall of the balloon 6, and the elastic silicone reinforcing ribs 10 extend along the axial direction of the balloon 6. During the balloon contraction process, the elastic silicone reinforcing ribs 10 limit the contraction of the balloon 6 in the axial direction and increase the contraction of the balloon in the circumferential direction, so that the balloon in the contracted state produces axial stripes, but no longitudinal stripes perpendicular to the axial direction, thereby reducing the pain caused to the patient during the insertion and removal of the catheter.

[0023] The novel urinary catheter of the present invention also has the following characteristics.

[0024] 1. Extended plug: The design of the extended plug 1 is adopted. The extended plug adopts a small outer diameter. The balloon 6 is pasted on the extended plug. The difference between the outer diameter of the balloon and the outer diameter of the tube body is very small, or even no difference. Such a design can reduce the pain of the patient when removing and inserting. This technology adopts a smooth balloon design. The balloon is pasted on the extended plug. The part where the extended plug is pasted adopts a small outer diameter design, so that the outer diameter of the balloon and the catheter body are almost the same, making the catheter smoother when inserted and removed, and reducing the pain of the patient when inserting and removing during use.

[0025] 2. Vertical stripe balloon: The balloon uses a vertical reinforcement rib design. After the balloon is inflated for a long time, the general catheter will produce horizontal wrinkles when it shrinks, which increases the pain of the patient when it is pulled out. The present invention adopts a vertical reinforcement rib design to reduce the generation of wrinkles when it shrinks. Even if wrinkles occur, the direction of the wrinkles is consistent with the direction of the stripes, which reduces the pain of the patient when it is pulled out. The balloon adopts a vertical stripe design to increase the strength of the balloon and prevent the balloon from rupture. At the same time, the vertical stripes make the wrinkles generated by the balloon when it shrinks also vertical, reducing the pain of the patient when it is pulled out.

[0026] 3. Connectors: The inner cavity of the extended plug 1 and the tube body 9 is connected by a connector, which includes a water injection port connector 7 and a flushing port connector 8, both of which are made of thin-walled elastic plastic or stainless steel, which can increase the firmness of the connection. In addition, due to the internal support of plastic or stainless steel, the toughness of the head end can be increased, solving the problem that silicone is soft and inconvenient to insert. When connecting the extended plug and the inner hole of the tube body, the present invention adopts a connector to connect them. The use of the connector not only increases the firmness of the connection, but also plays a role in supporting the catheter, making it more convenient to insert the catheter and reducing the burden on medical staff.

[0027] 4. Insertion and docking: The extended plug and the pipe body are connected by the insertion and docking method. Drill a hole on the pipe body with the same diameter as the connecting part of the extended plug, insert the extended plug into the pipe body, and bond it with glue to make the bonding more firm.

[0028] The novel urinary catheter of the present invention adopts a smooth design, and the balloon is of the same thickness as the tube body; and the balloon adopts a vertical grain design, so that the balloon will not produce horizontal wrinkles when it shrinks, alleviating the pain of patients during insertion and removal, and bringing better medical experience to patients.

[0029] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
