Description

Technical Field

[0001] This utility model relates to the field of urinary catheters, specifically a positioning component for urinary catheters. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is made of natural rubber, silicone rubber, or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, a balloon near the tip of the catheter secures the catheter in the bladder and prevents it from easily falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] For example, patent application CN 206275901 U discloses a novel urinary catheter belonging to the field of medical device structural design. This novel urinary catheter includes a catheter body and a silk fixing tape. The silk fixing tape is fixed to the tube connecting the balloon inflation port of the catheter body to the catheter body. A catheter clamp for clamping the drainage bag interface tube is fixed to the outside of the silk fixing tape. This novel urinary catheter overcomes the problems of cumbersome and time-consuming operation in fixing urinary catheters in the prior art. It also overcomes the problem of skin damage caused by the long-term fixation of the existing catheter clamp on the drainage bag interface tube. This novel urinary catheter is simple to operate and convenient to use, thus greatly saving fixation time, improving the work efficiency of medical staff, and has a simple structure with strong practicality.

[0004] Because the lower end of the urinary catheter needs to extend out of the bed and connect to the suspended urinary catheter bag via an insertion method, both the catheter and the urinary catheter are exposed on one side of the bed, and the catheter lacks a positioning mechanism. This makes it easy for people to bump into the catheter, causing it to detach from the urinary catheter bag and affecting its use. Therefore, there is an urgent need in the market to develop a positioning component for urinary catheters to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning component for a urinary catheter to solve the problem mentioned in the background art where the urinary catheter and urinary bag are exposed on one side of the bed and the urinary catheter is not equipped with a positioning mechanism, making it easy for personnel to collide with the urinary catheter, causing the urinary catheter to detach from the urinary bag and affecting its use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning component for a urinary catheter, comprising a fixing cylinder, a fixing tube fixedly disposed in the middle of the upper end face of the fixing cylinder, a urinary catheter bag disposed inside the fixing cylinder, a delivery tube fixedly disposed at the upper end of the urinary catheter bag, the upper end of the delivery tube extending through the middle of the fixing tube and extending out of the upper end of the fixing cylinder and fixedly connected to an umbrella-shaped connector, support rods fixedly connected on both sides of the middle of the upper end face of the fixing cylinder, a circular fixing seat fixedly connected at the upper end between the two support rods, a circular slot disposed in the middle of the circular fixing seat, a urinary catheter connected inside the circular slot, and a bolt connected to the middle of the front end of the circular fixing seat.

[0007] Preferably, the front end of the fixed cylinder is provided with an opening, and a connecting plate is fixedly connected to the rear end of the upper end face of the fixed cylinder.

[0008] Preferably, an internal thread is fixedly provided on the inner end face of the fixed tube, a connecting tube is fixedly connected to the conveying tube, and an external thread is fixedly connected to the outer side of the connecting tube.

[0009] Preferably, the conveying pipe and the fixed pipe are connected by a connecting pipe inserted into the fixed pipe and the internal thread and the external thread are threadedly connected and fixed.

[0010] Preferably, a limiting tube is fixedly connected to the urinary catheter, and the limiting tube is inserted into the circular slot of the circular fixing seat.

[0011] Preferably, the front end of the limiting tube is provided with a circular insertion hole, and the lower end of the catheter extends out to the lower end of the circular fixing seat and fits onto the umbrella-shaped insertion connector.

[0012] Preferably, the rear end of the bolt passes through the circular fixing seat and extends into the circular slot and is inserted into the circular insertion hole, and the bolt and the circular fixing seat are threaded together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a circular fixing base, the catheter is passed through the circular slot of the circular fixing base, and the circular insertion hole at the front end of the upper limit tube of the catheter is aligned with the position of the bolt. Then, the bolt is rotated so that its rear end passes through the circular slot and is inserted into the circular insertion hole, thereby fixing the limiting tube in the circular slot and achieving the limitation of the catheter. At this time, the lower end of the catheter is fitted onto the umbrella-shaped connector and connected to the delivery tube of the catheter bag. The setting of the circular fixing base effectively prevents the catheter from accidentally detaching from the catheter bag due to personnel touching it, improving the stability and safety of use.

[0015] 2. In this utility model, by setting a fixed tube, the delivery tube and the fixed tube are connected by a connecting tube inserted into the fixed tube and the internal thread and external thread are threadedly connected and fixed. After the fixed tube and the connecting tube are connected, the urine bag is hung. After the fixed tube and the connecting tube are separated, the urine bag can be removed from the front opening of the fixed tube, making the replacement of the urine bag more convenient.

[0016] 3. In this utility model, by setting the connecting plate, the upper end face of the fixed tube is fixedly connected to the connecting plate at the rear end. The connecting plate is fixed to the side of the bed to support the fixed tube, so that the fixed tube provides stable support for the catheter bag. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4An embodiment of this utility model provides a positioning component for a urinary catheter, comprising a fixing cylinder 1, a fixing tube 2 fixedly disposed in the middle of the upper end face of the fixing cylinder 1, a urinary catheter bag 3 disposed inside the fixing cylinder 1, a delivery tube 301 fixedly disposed at the upper end of the urinary catheter bag 3, the upper end of the delivery tube 301 passing through the middle of the fixing tube 2 and extending out of the upper end of the fixing cylinder 1 and fixedly connected to an umbrella-shaped connector 304, support rods 103 fixedly connected on both sides of the middle of the upper end face of the fixing cylinder 1, a circular fixing seat 4 fixedly connected at the upper end between the two support rods 103, a circular slot 401 disposed in the middle of the circular fixing seat 4, a urinary catheter 5 connected inside the circular slot 401, and a bolt 402 connected to the middle of the front end of the circular fixing seat 4.

[0024] Furthermore, the front end of the fixed cylinder 1 is provided with an opening 102, and the rear end of the upper end face of the fixed cylinder 1 is fixedly connected to a connecting plate 101. The connecting plate 101 is fixed to the side of the bed to support the fixed cylinder 1.

[0025] Furthermore, an internal threaded portion 201 is fixedly provided on the inner end face of the fixed tube 2, a connecting tube 302 is fixedly connected to the conveying tube 301, and an external threaded portion 303 is fixedly connected to the outside of the connecting tube 302.

[0026] Furthermore, the delivery tube 301 and the fixed tube 2 are connected by a connecting tube 302 inserted into the fixed tube 2, and the internal thread 201 and the external thread 303 are threadedly connected and fixed. After the fixed tube 2 and the connecting tube 302 are connected, the urinary catheter bag 3 is suspended. After the fixed tube 2 and the connecting tube 302 are separated, the urinary catheter bag 3 can be removed from the front opening 102 of the fixed tube 1, making the replacement of the urinary catheter bag 3 more convenient.

[0027] Furthermore, a limiting tube 501 is fixedly connected to the urinary catheter 5. The limiting tube 501 is inserted into the circular slot 401 of the circular fixing seat 4, and the circular fixing seat 4 limits the limiting tube 501 of the urinary catheter 5.

[0028] Furthermore, the front end of the limiting tube 501 is provided with a circular insertion hole 502, and the lower end of the catheter 5 extends out to the lower end of the circular fixing seat 4 and is fitted onto the umbrella-shaped insertion connector 304.

[0029] Furthermore, the rear end of the bolt 402 passes through the circular fixing seat 4 and extends into the circular slot 401 and is inserted into the circular insertion hole 502. The bolt 402 and the circular fixing seat 4 are threaded together. When the limiting tube 501 is inserted into the circular slot 401, the bolt 402 is rotated so that the rear end of the bolt 402 is inserted into the circular insertion hole 502 to limit the limiting tube 501 and prevent the limiting tube 501 from coming out of the circular slot 401. When an external force hits the catheter 5, the limiting state between the limiting tube 501 and the circular fixing seat 4 prevents the lower end of the catheter 5 from separating from the umbrella-shaped connector 304, thus affecting its use.

[0030] Working principle: In use, firstly, the fixing cylinder 1 is fixed to the side of the bed via the connecting plate 101. Then, the catheter bag 3 is connected to the fixing tube 2 inside the fixing cylinder 1 via the delivery tube 301 at its upper end. Specifically, the connecting tube 302 is inserted into the fixing tube 2, and the delivery tube 301 is rotated so that the external thread 303 on the outside of the connecting tube 302 is screwed into the internal thread 201 inside the fixing tube 2, thereby securely hanging the catheter bag 3 inside the fixing cylinder 1. Next, the catheter tube 5 is passed through the circular slot 401 of the circular fixing seat 4, and the circular insertion hole 502 at the front end of the upper limit tube 501 of the catheter tube 5 is aligned with the position of the bolt 402. Then, the bolt 402 is rotated so that its rear end passes through the circular slot 401 and is inserted into the circular insertion hole 502, thereby fixing the limit tube 501 in the circular slot 401 and limiting the catheter tube 5. At this point, the lower end of the catheter 5 is fitted onto the umbrella-shaped connector 304, connecting with the delivery tube 301 of the catheter bag 3. When the catheter bag 3 needs to be replaced, simply rotate the delivery tube 301 to separate the external thread 303 from the internal thread 201, and the catheter bag 3 can be removed from the opening 102 at the front end of the fixing cylinder 1. The operation is simple and quick. The positioning component effectively prevents the catheter 5 from accidentally dislodging from the catheter bag 3, improving the stability and safety of its use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
