Abstract

The utility model belongs to the field of medical equipment, specifically a three-cavity urinary catheter with an airtight joint, including a urination chamber, a water injection chamber and a flushing chamber, and is characterized in that an airtight joint is arranged at the flushing end, and the airtight joint is composed of a shell, Composition of puncture catheter and silicon sleeve: the shell is a hollow columnar structure, installed outside the flushing end; the bottom of the puncture catheter is fixed in the flushing end and communicated with the flushing end, and the top is conical and has 3 lateral side holes; A compressible silicone sleeve is placed between the catheters. The device does not need to use needles during operation, which can meet the requirements of bladder flushing flow rate, and at the same time prevent medical staff from being injured by needles; using the principle of positive pressure, the urine cannot flow back, so that the bladder flushing device is completely sealed, not easy to pollute, and will not slip off , reduce the incidence of urinary tract infection, and can meet the requirements of strict aseptic technology; the price of the bladder irrigator is relatively expensive, and the airtight joint can be directly connected with the infusion set or blood transfusion set to reduce the cost of rinsing.

Description

A three-lumen urinary catheter with an airtight connector

technical field

The utility model belongs to the field of medical equipment, in particular to a three-cavity urinary catheter with a sealed joint.

Background technique

A triple lumen catheter is a tube that is inserted through the urethra into the bladder to drain urine. In the existing medical system, the three-lumen urinary catheter can also be used for bladder irrigation and intravesical drug administration while indwelling the catheter.

The working principle of the three-chamber urinary catheter is to use the pressure of the bladder to excrete urine through the urination cavity; the balloon can inflate and block the bladder after being filled with water through the water injection cavity, and is used to fix the catheter during indwelling catheterization; flushing The cavity is used for flushing or intravesical administration, and the flushing end is open, and is directly connected with the flushing device during bladder flushing, and is blocked when not in use. It is mentioned in the literature that the heparin cap is connected to the flushing end of the urinary catheter, and the needle of the infusion set can be used to pierce the heparin cap during flushing; however, when the three-lumen urinary catheter is used for patients with urinary system tumors, especially when the patient is accompanied by hematuria, it is easy to occur Blood clots block the urinary catheter, which requires the flow rate of the flushing. If the flow rate of the needle is too slow, it cannot prevent the catheter from being blocked; in addition, the connection between the flushing end of the catheter and the heparin cap is not completely sealed, and there is a possibility of prolapse , the patient is at risk of potential infection.

Contents of the invention

Aiming at the problems existing in the design of the flushing end of the existing three-chamber urinary catheter, the utility model provides a three-chamber urinary catheter with an airtight joint.

A three-chamber urinary catheter with a closed joint of the utility model includes a urination chamber, a water injection chamber and a flushing chamber, and is characterized in that a closed joint is arranged at the flushing end, and the closed joint is composed of a shell, a puncture catheter and a silicon sleeve : The shell is a hollow columnar structure, installed outside the flushing end; the bottom of the puncture catheter is fixed in the flushing end and communicated with the flushing end; the top is conical and has 3 lateral side holes; a compressible tube is placed between the shell and the puncture catheter Silicon sleeve.

When in use, insert the airtight joint and the front end of the mastoid of the syringe or infusion set into the shell, the silicon sleeve is squeezed and compressed, and the fluid is injected from the syringe into the side hole of the puncture catheter, and then enters the bladder through the flushing chamber of the three-cavity catheter , to complete flushing or administration. The inside of the sleeve is always sterile and the surface can be wiped for disinfection.

Preferably, the silicon sleeve is formed by connecting several O-shaped silicon rings to ensure the elasticity of the silicon sleeve and maintain the memory of the closed system after injection. The top of the shell is equipped with a fluorescent ring to facilitate the operation of medical personnel at night.

The utility model is a three-chamber urinary catheter with an airtight joint, which does not need to use a needle during operation, can meet the requirements of the bladder flushing flow rate, and at the same time prevent medical staff from being stabbed by the needle; the principle of positive pressure is used to prevent urine from flowing back , so that the bladder irrigation device is completely sealed, not easy to be polluted, will not slip, reduces the incidence of urinary tract infection, and can meet the requirements of strict aseptic technology; the price of the bladder irrigation device is relatively expensive, and the airtight joint can be directly connected to the infusion set or blood transfusion set connection to reduce flushing costs.

Detailed ways

Embodiment 1: A three-chamber urinary catheter with a closed joint of the utility model includes a urination chamber, a water injection chamber and a flushing chamber, and is characterized in that a closed joint is provided at the flushing end 1-1, and the closed joint is formed by the casing 2-1. Composition of puncture catheter 2-2 and silicon sleeve: shell 2-1 has a hollow columnar structure and is installed on the outside of flushing end 1-1; the bottom of puncture catheter 2-2 is fixed in flushing end 1-1 and connected with flushing end 1-1 is connected, the top is conical and has three lateral side holes 2-3; a compressible silicon sleeve is placed between the shell 2-1 and the puncture catheter 2-2. The silicon sleeve is formed by connecting several O-shaped silicon rings to ensure the elasticity of the silicon sleeve and maintain the memory of the closed system after injection. The top of the shell 2-1 is equipped with a fluorescent ring to facilitate the operation of medical personnel at night.
