Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically a clinical drainage device. Background Technology

[0002] The scope of urological treatment mainly covers: various types of urinary stones and complex kidney stones; tumors of the kidneys and bladder; benign prostatic hyperplasia and prostatitis; inflammation and tumors of the testes and epididymis; hydrocele; various urinary system injuries; and congenital malformations of the urinary system, such as hypospadias, cryptorchidism, and hydronephrosis caused by ureteropelvic junction obstruction. After urological surgery, catheterization is often necessary.

[0003] However, when using existing urinary catheters, securing the balloon requires manually inserting a syringe into the injection valve, then injecting liquid into the balloon to inflate and secure it. After use, the liquid also needs to be withdrawn. This process involves many steps and requires the assistance of other instruments, making it time-consuming and labor-intensive. Furthermore, the urine drainage bags of existing urinary catheters have a simple structure and lack any warning signs. If the urine is not cleaned in time when it accumulates, it will affect the drainage effect.

[0004] Therefore, a clinical drainage device is needed to improve the above problems. Utility Model Content

[0005] To address the problems of existing urinary catheters used for drainage, which require manual insertion of a syringe into the injection valve to inflate and secure the balloon, followed by removal of the fluid after use, this invention provides a clinical drainage device to solve these issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clinical drainage device includes a drainage catheter with an expansion ring at one end. A discharge housing is installed on one side of the expansion ring at the port of the drainage catheter, and a connecting groove is formed annularly on the outer wall of the discharge housing. A connecting block is installed at one end of the drainage catheter, and a connecting tube is provided on the outer wall of the connecting block. One end of the connecting tube passes through the drainage catheter and extends to the inner wall of the drainage catheter, where the expansion ring is connected. A fixing component is installed at the other end of the connecting tube. A discharge tube is installed on one side of the connecting tube at the outer wall of the connecting block, wherein a fluid storage component is installed at one end of the discharge tube, and a limit block is provided on the outer wall of the discharge tube.

[0008] As a preferred embodiment of this utility model, the fixing component includes a limiting shell and a liquid storage bladder. The liquid storage bladder is installed at the port of the connecting pipe. The limiting shell is installed on one side of the liquid storage bladder and on the outer wall of the connecting pipe. A limiting sleeve is provided on the outer wall of the limiting shell. A double-headed reverse threaded rod is rotatably connected to the inner wall of the limiting sleeve.

[0009] As a preferred embodiment of this utility model, the outer walls of the double-ended reverse threaded rod are threaded with limiting blocks, wherein the limiting blocks are located in the inner cavity of the limiting housing, and the connecting pipe is located between the limiting blocks. One end of the double-ended reverse threaded rod passes through the limiting sleeve and extends to the outer wall of the limiting sleeve, where a lever is connected.

[0010] As a preferred embodiment of this utility model, a limiting slide rod is slidably connected to the outer wall of the limiting clamping block, wherein two sets of limiting slide rods are provided and are respectively located on the outer wall of the limiting housing, and the limiting slide rod is located on one side of the connecting pipe, and the connecting pipe is located on one side of the double-headed reverse threaded rod.

[0011] As a preferred embodiment of this utility model, the liquid storage assembly includes a one-way valve, which is installed at the port of the outlet pipe, wherein the flow direction of the one-way valve is from the inside to the outside of the outlet pipe, and an installation housing is installed at one end of the one-way valve.

[0012] As a preferred embodiment of this utility model, a controller is embedded in the outer wall of the mounting housing, a buzzer is installed on the outer wall of the controller, a light bulb is installed on one side of the controller and on the outer wall of the mounting housing, a drainage bag is installed at one end of the mounting housing, and positive and negative electrode patches are installed on the inner wall of the drainage bag opposite to it.

[0013] As a preferred embodiment of this utility model, the controller is connected to a buzzer, a light bulb, and positive and negative electrode patches via wires, and the connection method is electrical connection. Multiple sets of connecting grooves are opened and are located on the outer wall of the outlet shell. The outlet shell and the expansion ring are made of medical rubber material, and the connection between the connecting tube and the expansion ring is a connecting structure.

[0014] As a preferred embodiment of this utility model, the inner cavity of the liquid storage bladder is filled with pure water, the cross-section of the limiting shell is a rectangular structure, two sets of limiting sleeves are provided and are respectively located on the opposite outer walls of the limiting shell, and the connecting pipe is located between the limiting slide rod and the double-ended reverse thread rod.

[0015] Compared with existing technologies, this invention enables the injection of water into the expansion ring and its fixation by setting a fixing component in the clinical drainage device. When purified water in the reservoir cavity is injected into the inner cavity of the expansion ring through the connecting tube, the expansion ring expands and is fixed. At the same time, when the user rotates the lever to rotate the double-ended reverse threaded rod, the limiting clamps on both sides of the connecting tube move respectively, causing the limiting clamps to move towards the center on the outer wall of the double-ended reverse threaded rod, thereby clamping and limiting the connecting tube. When the connecting tube is flattened by the limiting clamps on both sides, the liquid in the inner cavity of the expansion ring cannot flow back, thus keeping the expansion ring in an expanded state and limiting it. This solves the problem that existing urinary catheters require many steps and other instruments, which is time-consuming and labor-intensive.

[0016] This invention enables monitoring of urine within the drainage bag by incorporating a fluid storage component in the clinical drainage device. When there is a significant amount of urine in the drainage bag, and the urine simultaneously contacts the positive and negative electrode patches, the patches are activated, generating an electrical signal. This signal is then transmitted via wires to the controller, which in turn activates a buzzer to produce an audible sound. Simultaneously, the controller illuminates a light bulb, prompting the operator to clean the drainage bag promptly. This addresses the problem of existing urinary catheter drainage bags where failure to clean them promptly when there is a large amount of urine can negatively impact drainage effectiveness.

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5 A clinical drainage device is shown, including a drainage conduit 1, an expansion ring 2 at one end of the drainage conduit 1, an outlet housing 3 installed on one side of the expansion ring 2 and at the port of the drainage conduit 1, and a connecting groove 4 annularly formed on the outer wall of the outlet housing 3, a connecting block 5 installed at one end of the drainage conduit 1, a connecting tube 6 installed on the outer wall of the connecting block 5, one end of the connecting tube 6 penetrating the drainage conduit 1 and extending to the inner wall of the drainage conduit 1 and connected to the expansion ring 2, a fixing component 7 installed at the other end of the connecting tube 6, an outlet tube 8 installed on one side of the connecting tube 6 and at the outer wall of the connecting block 5, wherein a liquid storage component 9 is installed at one end of the outlet tube 8, and a limit block 10 is provided on the outer wall of the outlet tube 8.

[0025] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4The fixing component 7 includes a limiting housing 701 and a liquid storage bladder 702. The liquid storage bladder 702 is installed at the port of the connecting pipe 6. The limiting housing 701 is installed on one side of the liquid storage bladder 702 and on the outer wall of the connecting pipe 6. A limiting sleeve 703 is provided on the outer wall of the limiting housing 701. A double-ended reverse threaded rod 704 is rotatably connected to the inner wall of the limiting sleeve 703. A limiting clamp 705 is threadedly connected to the opposite outer wall of the double-ended reverse threaded rod 704. The limiting clamp 705 is located within the limiting housing. The inner cavity of body 701, and the connecting pipe 6 is located between the limiting clamps 705. One end of the double-headed reverse threaded rod 704 passes through the limiting sleeve 703 and extends to the outer wall of the limiting sleeve 703, where a lever 706 is connected. The outer wall of the limiting clamp 705 is slidably connected to the limiting slide rod 707, wherein two sets of limiting slide rods 707 are provided and are respectively located on the outer wall of the limiting housing 701, and the limiting slide rod 707 is located on one side of the connecting pipe 6, and the connecting pipe 6 is located on one side of the double-headed reverse threaded rod 704.

[0026] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 5 The liquid storage assembly 9 includes a one-way valve 901, which is installed at the port of the outlet pipe 8. The flow direction of the one-way valve 901 is from the inside to the outside of the outlet pipe 8. A mounting housing 902 is installed at one end of the one-way valve 901. A controller 903 is embedded in the outer wall of the mounting housing 902. A buzzer 904 is installed on the outer wall of the controller 903. A light bulb 905 is installed on one side of the controller 903 and on the outer wall of the mounting housing 902. A drainage bag 906 is installed at one end of the mounting housing 902. Positive and negative electrode patches 907 are installed on the inner wall of the drainage bag 906.

[0027] Based on the above structural features and connection relationship, the positive and negative electrode patches 907 are located at the connection between the mounting housing 902 and the drainage bag 906, and the positive and negative electrode patches 907 are located in the inner cavity of the mounting housing 902. When there is a lot of urine, the urine will come into contact with the positive and negative electrode patches 907 at the same time, so that it will be energized to generate an electrical signal.

[0028] The controller 903 is electrically connected to the buzzer 904, the bulb 905, and the positive and negative electrode patches 907 via wires, thereby energizing the device. This allows the controller 903 to control the operation of the buzzer 904, the bulb 905, and the positive and negative electrode patches 907. Multiple sets of connecting grooves 4 are located on the outer wall of the outlet housing 3. The outlet housing 3 and the expansion ring 2 are made of medical rubber. The connection between the connecting pipe 6 and the expansion ring 2 is a connecting structure. The inner cavity of the reservoir 702 is filled with pure water. The cross-section of the limiting housing 701 is rectangular. Two sets of limiting sleeves 703 are located on the opposite outer walls of the limiting housing 701. The connecting pipe 6 is located between the limiting slide rod 707 and the double-ended reverse threaded rod 704.

[0029] When this clinical drainage device is in operation, the drainage catheter 1 is inserted into the patient's bladder. Once the drainage catheter 1 reaches the appropriate position, the reservoir 702 is pinched, allowing purified water inside the reservoir 702 to be injected into the inner cavity of the expansion ring 2 through the connecting tube 6. This causes the expansion ring 2 to inflate into a ring-shaped airbag for fixation. Simultaneously, the user rotates the lever 706, causing the double-ended reverse-threaded rod 704 to rotate. When the double-ended reverse-threaded rod 704 rotates, due to the threaded connection of limit clamps 705 on the opposing outer walls of the double-ended reverse-threaded rod 704, with the limit clamps 705 located inside the limit housing 701 and the connecting tube 6 positioned between the limit clamps 705, the limit clamps on both sides of the connecting tube 6 will... The blocks 705 move separately, causing the limiting clamps 705 to move towards the center on the outer wall of the double-ended reverse threaded rod 704. At the same time, the limiting clamps 705 slide on the outer wall of the limiting slide rod 707, thereby clamping and limiting the connecting tube 6. When the connecting tube 6 is flattened by the limiting clamps 705 on both sides, the liquid in the inner cavity of the expansion ring 2 cannot flow back, thus keeping the expansion ring 2 in an expanded state for limitation. When it is necessary to remove the drainage catheter 1, simply release the limiting clamps 705 to allow the purified water in the inner cavity of the expansion ring 2 to flow back to the reservoir 702. The device is relatively simple to use, thus solving the problem that the existing urinary catheters require many steps and other instruments, which is time-consuming and labor-intensive.

[0030] When the drainage catheter 1 is inserted into the patient's bladder, the urine in the bladder cavity flows through the drainage catheter 1 and the outlet tube 8. The urine then flows sequentially through the outlet tube 8, the one-way valve 901, and the mounting housing 902 into the inner cavity of the drainage bag 906. When there is a large amount of urine in the inner cavity of the drainage bag 906, when the urine simultaneously contacts the positive and negative electrode patches 907, the patches are conductive, generating an electrical signal. Simultaneously, the positive and negative electrode patches 907 transmit this signal through wires to the controller 903, which in turn controls the buzzer 904 to produce a buzzing sound. At the same time, the controller 903 controls the bulb 905 to illuminate, prompting the operator to clean the drainage bag 906 promptly. This solves the problem of existing urinary catheter drainage bags where failure to clean them promptly when there is a large amount of urine affects the drainage effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
