Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, and in particular to a nursing catheter. Background Technology

[0002] A urinary catheter is an important medical device primarily used to drain urine from a patient's bladder. It is suitable for various clinical situations, including urinary retention, during surgery, and postoperative care. Traditional urinary catheters are typically made of soft and flexible materials such as polyvinyl chloride (PVC), silicone, or latex to minimize damage to the urethra and bladder. These catheters usually have a tip at one end for insertion into the urethra, and the other end is connected to a collection bag or other collection device.

[0003] To prevent catheters from becoming dislodged during use due to movement or turning over, existing catheters typically have a small inflatable balloon at the end that enters the bladder. However, this method has certain limitations in practice. First, balloon inflation requires injecting air or saline solution into the balloon with a syringe after catheter insertion, meaning an extra syringe is needed for each insertion. Second, this process increases the workload for medical staff, and improper operation may result in the balloon not inflating sufficiently, thus affecting the catheter's fixation. Utility Model Content

[0004] The purpose of this invention is to provide a nursing catheter that has a built-in structure for inflating a balloon, making operation simpler and more convenient, and reducing the consumption of additional instruments.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A nursing catheter includes a catheter body, in which a catheter channel and an inflation channel are provided along its length. One end of the catheter body has a urine inlet communicating with the catheter channel. A fixed air bladder communicating with the inflation channel is provided on the outer wall of the catheter body near the urine inlet. A compression corrugated tube is provided at the end of the catheter body away from the urine inlet, and the compression corrugated tube is communicating with the inflation channel. An inner guiding tube communicating with the catheter channel is provided inside the compression corrugated tube of the catheter body. A connecting tube is provided outward from the end of the compression corrugated tube away from the catheter body. An outer tube, which is fitted inside the compression corrugated tube and is slidably and sealingly connected to the inner guiding tube, is provided through the connecting tube.

[0007] By adopting the above technical solution, when inserting the urinary catheter, after inserting the catheter body along the urethra, press the compression wave tube to compress it and deflate it. Air is then injected into the fixation balloon through the inflation channel, causing the fixation balloon to expand and provide support and fixation. During this process, the connection between the inner guide tube and the outer tube becomes tighter, and the compression wave tube will not automatically return to its original position. When it is necessary to remove the urinary catheter, the compression wave tube is gradually pulled back to its original position, and the air in the fixation balloon is drawn back into the compression wave tube. At this time, the fixation balloon deflates, and the urinary catheter body can be removed.

[0008] A further feature of this invention is that: a fixed contact plate connected to the compression wave tube is provided at one end of the catheter body away from the urinary inlet, and a movable contact plate that cooperates with the fixed contact plate is provided at one end of the compression wave tube away from the catheter body.

[0009] A further feature of this invention is that the edge of the fixed contact plate is provided with multiple connection slots, and the edge of the movable contact plate facing the fixed contact plate is provided with multiple connection strips that cooperate with the connection slots.

[0010] A further feature of this invention is that the catheter body is made of polyurethane, and the compression corrugated tube is made of polyvinyl chloride.

[0011] In summary, this utility model has the following beneficial effects: This utility model inflates the balloon by pressing and compressing the wave tube. The new catheter simplifies the balloon inflation process, reduces the need for syringes, thereby reducing medical costs and improving the work efficiency of medical staff. At the same time, it ensures that the balloon can be stably inflated, effectively preventing the catheter from shifting or falling off during use, thus improving patient safety and comfort.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Example, refer to Figure 1-2 A nursing catheter includes a catheter body 1 made of polyurethane material. The catheter body 1 has a catheter channel 2 and an inflation channel 3 arranged along its length. One end of the catheter body 1 has a urine inlet 4 that communicates with the catheter channel 2. The outer wall of the catheter body 1 is provided with a fixed air bag 5 that communicates with the inflation channel 3 near the urine inlet 4.

[0018] The catheter body 1 has a section of compression corrugated tube 6 made of polyvinyl chloride at the end away from the inlet 4. The compression corrugated tube 6 is connected to the inflation channel 3. The catheter body 1 has an inner guide tube 7 inside the compression corrugated tube 6 that is connected to the catheter channel 2. The end of the compression corrugated tube 6 away from the catheter body 1 has a connecting tube 8 that is used to connect to the drainage tube. The connecting tube 8 has an outer tube 9 that is slidably connected to the inner guide tube 7 inside the compression corrugated tube 6, so that the inner guide tube 7 and the outer tube 9 can always maintain a sealed connection when the compression corrugated tube 6 is pressed.

[0019] The end of the catheter body 1 away from the inlet 4 is provided with a fixed contact plate 10 that connects to the compression wave tube 6. The end of the compression wave tube 6 away from the catheter body 1 is provided with a movable contact plate 11 that cooperates with the fixed contact plate 10. The edge of the fixed contact plate 10 has two connecting slots 12. The edge of the movable contact plate 11 facing the fixed contact plate 10 has two connecting strips 13 that cooperate with the connecting slots 12. After the connecting strips 13 are connected to the connecting slots 12, the compression wave tube 6 is more difficult to reset.

[0020] Instructions for use: When inserting the catheter, insert the catheter body 1 along the urethra, press the compression wave tube 6 to compress it and deflate it. Inflate the fixing balloon 5 through the inflation channel 3, causing the fixing balloon 5 to expand and provide support and fixation. During the process, the inner guide tube 7 and the outer tube 9 are more securely connected, and the compression wave tube 6 will not automatically return to its original position due to the connection between the connecting clip 13 and the connecting slot 12. When it is necessary to remove the catheter, pull the movable contact plate 11 to gradually pull the compression wave tube 6 back to its original position, drawing the air out of the fixing balloon 5 back into the compression wave tube 6. At this time, the fixing balloon 5 will deflate, and the catheter body 1 can be pulled out.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
