Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical equipment for nephrology, in particular to a urinary catheter conversion joint. Background Art
[0002] As a common medical auxiliary tool, urinary catheter plays an important role in clinical applications. The main function of urinary catheter is to drain urine, relieve bladder pressure and protect kidney function. Its characteristics include softness, easy insertion, good biocompatibility and good drainage effect.
[0003] The structure of the urinary catheter includes a catheter head at the tip of the catheter, which is responsible for inserting into the patient's urethra. The catheter head is provided with an air bag. When the air bag is filled with water or air, it will expand to form a sealed barrier to prevent the catheter from accidentally slipping out of the urethra. The catheter body is the main part of the urinary catheter, which is responsible for drawing urine from the bladder. The catheter body is usually made of soft material. One end of the catheter body is connected to the catheter head, and the other end is connected to a parallel water (air) injection valve and a drainage cavity. The water injection valve is responsible for injecting water into the air bag, and the drainage cavity is used to draw urine from the bladder. The end of the drainage cavity is usually connected to a collection bag or drainage bottle to collect and process urine. The inside of the catheter body has a water injection channel connected to the air bag and a drainage channel connected to the catheter head. The two channels extend in parallel.
[0004] During treatment, the patient's bladder and urethra not only need drainage, but also often need to be flushed with drugs through a catheter. A common measure is to directly inject the drug solution with a syringe from the drainage head, insert the syringe needle into the drainage channel in the drainage cavity, flush, and discharge it from the drainage cavity after reflux; however, such operation makes it easy for the needle to penetrate the injection channel and the drainage channel at the same time, causing the air bag to leak and shrink, causing the catheter to fall out, resulting in treatment errors, and the syringe is generally fixed to the drainage cavity by bonding during the injection process, which is easy to fall off, delaying treatment.
[0005] Therefore, in order to effectively solve the problems existing in the existing urinary catheter treatment, the utility model provides a urinary catheter conversion joint. Utility Model Content
[0006] The utility model aims to overcome the defects described in the background technology, thereby providing a urinary catheter conversion joint.
[0007] To achieve the above purpose, the technical solution of the utility model is:
[0008] Provided is a urinary catheter conversion joint, comprising a conical joint connected to a drainage head of the urinary catheter. Because the urinary catheter is made of elastic material as a whole, it is easier to insert other joints externally through the conical structure in order to facilitate connection; the conical end of the conical joint is inserted into the drainage cavity of the urinary catheter, and the other end is plugged with a Y-shaped joint; the Y-shaped joint comprises an upper plug plugged with the conical joint, the lower end of the upper plug is respectively connected to a urinary tube and an injection tube, and the end of the injection tube is fixed with a positive pressure joint for connecting a syringe; the positive pressure joint has a one-way injection sealing function, belongs to the prior art, and is not described in detail here; the urinary tube is connected to a urinary bag through a urine bag plug.
[0009] The urinary catheter comprises a tube body, the upper end of which is connected to a urinary catheter head, and an air bag is arranged on the urinary catheter head.

After the injection is completed, the syringe and the cover are pulled out, and the patient can perform normal urination and drainage; the specific operation is: the urine bag is plugged into the urine bag plug through the urine bag connecting tube, and due to the unidirectionality of the positive pressure joint, the injection tube is sealed at this time, and the patient's urine is discharged into the urine bag through the urinary catheter, thereby avoiding the treatment errors caused by the air bag losing water and the urinary catheter coming out due to the insertion of the syringe needle into the drainage cavity in conventional treatment.
[0010] Furthermore, a conical urine bag plug is integrally formed at the end of the urination tube, the urine bag plug is connected to the urine bag connecting tube, and annular protrusions are evenly distributed on the conical outer peripheral surface of the urine bag plug, which can effectively prevent the urine bag from falling off.
[0011] Preferably, the Y-shaped connector and the conical connector are made of PP plastic. PP plastic has excellent chemical resistance and heat resistance and is commonly used in the production of medical syringes, making it convenient to use the device as a disposable consumable, which is hygienic and convenient.
[0012] Preferably, a sealing cap is sleeved on the end of the urinary tube, and the sealing cap is made of medical silicone, which can block the urinary tube to prevent leakage during drug injection and flushing.

[0014] 1. The Y-shaped connector is used to achieve the separate sealing operation of drainage and injection therapy, avoiding the treatment errors caused by the insertion of the syringe needle into the drainage cavity in conventional treatment, which may cause the air bag to lose water and the catheter to fall out.

DETAILED DESCRIPTION
[0020] The following is a more detailed description of the urinary catheter conversion joint of the present invention in conjunction with the accompanying drawings and through specific implementation methods.
[0021] like Figure 1 - Figure 3 As shown:
[0022] The utility model relates to a urinary catheter conversion joint, comprising a conical joint 7 connected to the drainage head of the urinary catheter. Since the urinary catheter is made of elastic material as a whole, it is easier to insert other joints externally through the conical structure in order to facilitate connection; the conical end of the conical joint 7 is inserted into the drainage cavity 101 of the urinary catheter, and the other end is plugged with a Y-shaped joint 2; the Y-shaped joint 2 comprises an upper plug 203 plugged with the conical joint 7, and the lower end of the upper plug 203 is respectively connected to a urine discharge tube 202 and an injection tube 201, and the end of the injection tube 201 is fixed with a positive pressure joint 3 for connecting a syringe; the positive pressure joint 3 has a one-way injection sealing function, belongs to the prior art, and is not described in detail here; the urine discharge tube 202 is connected to a urine bag through a urine bag plug 4.
[0023] The urinary catheter comprises a tube body 1, the upper end of which is connected to a urinary catheter head 104, on which an air bag 103 is arranged. When the device is used, the patient first inserts the urinary catheter head 104 into the urinary catheter, and fills the air bag 103 with water through the water injection valve 102, so that the urinary catheter head 104 is fixed in the patient's urethra. The drainage cavity tube 101 is responsible for urination and drug injection treatment, which is specifically achieved through a Y-shaped connector 2; wherein, the injection tube 201 is fixedly connected to a positive pressure connector 3. When flushing or drug injection treatment is required, the syringe is connected to the positive pressure connector 3, and the urinary tube 202 is sealed with a cover 6, and drugs or saline are injected into the inside. After the injection and flushing are completed, the syringe and the cap 6 are pulled out, and the patient can perform normal urination and drainage; the specific operation is: the urine bag is plugged into the urine bag plug 4 through the urine bag connecting tube 5. Due to the unidirectionality of the positive pressure joint 3, the injection tube 201 is sealed at this time, and the patient's urine is discharged into the urine bag through the urination tube 202, avoiding the treatment errors caused by the air bag 103 losing water and the catheter coming out due to the insertion of the syringe needle into the drainage cavity in conventional treatment; the positive pressure joint 3 for injection and the urine bag plug 4 are designed as one piece through the Y-shaped joint 2, which reduces the time of replacing different consumables one by one and improves efficiency.
[0024] A conical urine bag plug 4 is integrally formed at the end of the urination tube 202, and the urine bag plug 4 is connected to the urine bag connecting tube 5. Annular protrusions 401 are evenly distributed on the conical outer peripheral surface of the urine bag plug 4, which can effectively prevent the urine bag from falling off.
[0025] The material of the Y-shaped connector 2 and the conical connector 7 is PP plastic. PP plastic has excellent chemical resistance and heat resistance and is commonly used in the production of medical syringes. It is convenient to use the device as a disposable consumable, which is hygienic and convenient.
[0026] like Figure 3 As shown, a sealing cap 6 is sleeved on the end of the urinary tube 202. When injecting medicine and flushing, the urine bag is pulled out and the urinary tube 202 can be blocked by the sealing cap 6 to prevent leakage.
