Description

Technical Field

[0001] This invention relates to the field of intermittent catheter technology, and more specifically, to an integrated anti-reflux intermittent catheter drainage device and its application method. Background Technology

[0002] Intermittent urinary catheters used clinically are single catheters, with or without lubricant. During the procedure, the intermittent urinary catheter needs to be removed entirely from its sterile packaging bag. This type of catheter has the following drawbacks:

[0003] 1. The removal process can easily lead to catheter contamination;

[0004] 2. When catheterization is completed, there is no device to prevent the backflow of urine in the catheter caused by the body's siphon effect, which can easily lead to urinary tract infections during use;

[0005] 3. The catheter lacks an insertion depth marker, making it impossible for the operator to determine the insertion depth at all times;

[0006] 4. The lack of urine collection and drainage devices means that additional urine collection items and devices need to be prepared during the catheterization process, which can easily lead to urine spillage and environmental pollution.

[0007] 5. Intermittent catheterization requires many supplies and is complicated to perform, leading to poor patient compliance.

[0008] There is a need for an integrated anti-reflux intermittent urinary catheterization and drainage device and its application method that can overcome the above-mentioned defects. Summary of the Invention

[0026] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort:

[0027] Figure 1 This is a schematic diagram of the integrated anti-reflux intermittent urinary catheterization and drainage device according to a preferred embodiment of the present invention;

[0028] Figure 2 This is a flowchart illustrating the application method of the integrated anti-reflux intermittent catheterization and drainage device according to a preferred embodiment of the present invention. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0030] The preferred embodiment of the present invention is an integrated anti-reflux intermittent urinary catheterization and drainage device, such as... Figure 1As shown, the device includes a bag body 1 and a graduated catheter 2. The bag body 1 contains a catheter storage chamber 10 and a urine collection chamber 11 arranged side-by-side. A transfer chamber 12 connects the upper ends of the catheter storage chamber 10 and the urine collection chamber 11. Both the catheter storage chamber 10 and the transfer chamber 12 are filled with a hydrophilic lubricant. The urine collection chamber 11 is graduated. An opening connecting the transfer chamber is located at the upper end of the bag body 1, and a guide sheath 3 is installed at the opening. The end of the catheter 2 is equipped with a push handle 20 and a closing valve 21.

[0031] In the initial state, most of the catheter body of the catheter 2 is located in the catheter storage chamber 10, a small part of the catheter body of the catheter 2 is located in the transfer chamber 12, and the head of the catheter 2 is located at the guide sheath 3, and the sealing valve 21 is open.

[0032] In use, guided by the guide sheath 3, the push handle 20 is operated through the bag body 1 to push the catheter 2, which is coated with hydrophilic lubricant, out of the bag body 1 until the tail end of the catheter 2 is located in the transfer chamber 12; after successful catheterization, the tail end of the catheter 2 is pushed into the urine collection chamber 11 to facilitate urine collection and calculation of urine volume.

[0033] After catheterization is completed, close the sealing valve 21 to prevent urine backflow;

[0034] By applying the method of this invention, the urinary catheter, hydrophilic lubricant, urine collection cavity, and guide sheath are designed as a single unit, which can effectively solve a series of problems existing in the prior art. It is easy to operate, has good integrity, and is low in cost. The whole device is easy to use and operate in clinical practice, ensures patient safety, reduces the occurrence of urinary tract infections, improves patient compliance, and brings great convenience to urinary catheterization.

[0035] Preferably, the urine collection chamber 11 is provided with a scale for a capacity of 50-1200 ml. Of course, this range is only an example and is not intended to be limited. Other ranges can be designed as needed.

[0036] Preferably, the guide sheath 3 includes a guide sheath seat 30 inserted through the opening and a guide head 31 fixed to the front end of the catheter 2. The guide sheath 3 also includes a removable protective sleeve 32 covering the guide head 31. The structure is simple. When performing intermittent catheterization, the intermittent catheter is introduced into the urethra from the guide sheath, reducing irritation to the urethral opening. The guide sheath head is provided with a protective sleeve. The protective sleeve is removed before catheterization to avoid contamination.

[0037] A preferred guide head structure may be: the front end of the guide head 31 is arc-shaped and has a through hole that connects to the inner hole of the urinary catheter 2; of course, other existing guide sheath 3 styles may also be used, and there is no limitation on this; the guide head may be made of silicone or the like.

[0038] Preferably, the outer surface of the bag 1 is marked to distinguish between male and female use; wherein, the catheter in the bag for male use has a length scale of 0-40CM, and the catheter in the bag for female use has a length scale of 0-25CM; of course, the above numerical range is only an example and is not intended to limit, and other numerical ranges can be designed as needed.

[0039] Preferably, the closing valve is a push-button valve (the valve structure can be any existing structure and is not limited thereto). The operation of closing and removing the urinary catheter can be completed by pressing outside the bag, which is relatively convenient. Of course, other types of valves, such as rotary valves, can also be used to implement this solution, but they will be relatively less convenient.

[0040] Preferably, the push handle 20 and the push valve 21 are integrally formed, which can reduce the manufacturing cost; of course, the solution can also be implemented in a separate design, and it also falls within the protection scope of this application.

[0041] Preferably, the upper part of the bag body 1 is provided with a hanging hole 13. The diameter of the hanging hole can be designed to be 1 cm (this value is only an example and is not intended to limit). Before catheterization, it can be hung on a wall hook for easy access. After catheterization, the urine collection bag can be vertically erected to facilitate the measurement of urine volume or urine weight.

[0042] A method for applying an integrated anti-reflux intermittent urinary catheterization and drainage device, wherein the integrated anti-reflux intermittent urinary catheterization and drainage device as described above is used. Figure 2 As shown, the implementation method is as follows:

[0043] S01: In the initial state, most of the catheter body is located in the catheter storage chamber, a small part of the catheter body is located in the transfer chamber, and the head of the catheter is located at the guide sheath, with the sealing valve open.

[0044] S02: When in use, under the guidance of the guide sheath, operate the push handle through the bag to push the catheter coated with hydrophilic lubricant out of the bag until the end of the catheter is in the transfer chamber;

[0045] S03: After successful catheterization, push the end of the catheter into the urine collection chamber to facilitate urine collection and calculation of urine volume.

[0046] S04: After catheterization is completed, close the sealing valve to prevent urine backflow;

[0047] By applying the method of this invention, the urinary catheter, hydrophilic lubricant, urine collection cavity, and guide sheath are designed as a single unit, which can effectively solve a series of problems existing in the prior art. It is easy to operate, has good integrity, and is low in cost. The whole device is easy to use and operate in clinical practice, ensures patient safety, reduces the occurrence of urinary tract infections, improves patient compliance, and brings great convenience to urinary catheterization.

[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
