Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a disposable temperature and pressure measuring urinary catheter. Background Art

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. Some catheters are used in conjunction with a monitor. Medical staff use the monitor to understand the temperature and pressure of the patient's urine. It has the function of measuring temperature and pressure. In order to prevent cross infection, this type of catheter that can measure temperature and pressure is generally made of disposable silicone material, and the patient can directly discard and replace it after use. The following problems exist in the existing technology:

[0003] Because when the existing disposable temperature and pressure measuring catheter is connected to the monitor for temperature and pressure measurement, the catheter can only be attached to the patient's skin by means of a separately prepared tape due to its long length, and the silicone catheter is relatively soft and can be easily squeezed on the patient's body, resulting in the inability of urine to pass smoothly, affecting the normal use of the catheter. At the same time, the existing disposable temperature and pressure measuring catheter needs to be connected to a urine bag tube and a temperature and pressure sensor data cable for connection to the monitor, and the connection can only rely on the elasticity of the silicone material, resulting in the possibility of separation of the connection once the catheter is pulled, thereby affecting normal catheterization.

The two positioning base plates are fixedly connected to the bottom of the catheter and the temperature and pressure measuring tube by the positioning nails, and flexible metal arc plates are fixedly installed on the left and right sides of the top of the two positioning base plates. The catheter and the temperature and pressure measuring tube are respectively located between the opposite surfaces of the flexible metal arc plates on the left and right sides of the top of the two positioning base plates.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a disposable temperature and pressure measuring urinary catheter, comprising a urinary catheter 1, a pressure relief port 2 is fixedly connected to the right side of the front end of the urinary catheter 1, a temperature and pressure measuring tube 3 is fixedly connected to the left side of the front end of the urinary catheter 1, a urine bag connecting tube 4 is clamped on the inner ring of the front end of the urinary catheter 1, a temperature and pressure measuring sensor line 5 is clamped on the inner ring of the front end of the urinary catheter 1, the urine bag connecting tube 4 is externally connected to the urine bag, and the temperature and pressure measuring sensor line 5 is externally connected to the temperature and pressure measuring monitor, and three urinary catheter positioning mechanisms 6 are evenly fixedly installed on the outer wall of the urinary catheter 1, and the three urinary catheter positioning mechanisms 6 all include fixing rings 61, and the three fixing rings 61 are fixedly installed on the outer wall of the urinary catheter 1 respectively. The upper and lower sides of the three fixing rings 61 are fixedly installed with rubber pads 62, so that the fixing rings 61 contacting the patient's skin feel more comfortable. The left and right sides of the three fixing rings 61 are movably installed with rotating blocks 63. The side of the rotating block 63 away from the fixing ring 61 is fixedly installed with a positioning belt 64. Through the rotatable positioning belt, the catheter 1 can be quickly positioned regardless of whether it is facing the patient's skin from the top or the bottom. The bottom of the positioning belt 64 is fixedly bonded with an adhesive layer 641, and the bottom of the adhesive layer 641 is fixedly bonded with a protective paper 642. The side of the protective paper 642 away from the rotating block 63 is fixedly connected with a pulling extension paper 643;

[0021] When using the catheter 1, the rotating blocks 63 on the left and right sides of the three fixing rings 61 on its outer wall are rotated until the adhesive layer 641 below the positioning belt 64 faces the patient's skin, and then the protective paper 642 at the bottom of the adhesive layer 641 is torn off by pulling the stretching paper 643, so that the adhesive layer 641 is used to fix the entire positioning belt 64 on the patient's skin, so that the catheter positioning mechanism 6 completes the fixation of the catheter 1, so that the catheter 1 is stably adhered to the patient's skin to prevent bending, and then one end of the input end of the urine bag connecting tube 4 is inserted into the front end inner cavity of the catheter 1, and the temperature and pressure data sensor line of the monitor is inserted into the front end of the temperature and pressure measuring tube 3 to complete the connection.

[0022] like Figure 4 , Figure 5 As shown, the bottom of the front end outer wall of the urinary catheter 1 and the temperature and pressure measuring tube 3 are both provided with a positioning base plate 11, and a positioning nail 12 is penetrated through the bottom of the positioning base plate 11. The two positioning base plates 11 are fixedly connected with the bottom of the urinary catheter 1 and the temperature and pressure measuring tube 3 by using the positioning nail 12. Flexible metal arc plates 13 are fixedly installed on the left and right sides of the top of the two positioning base plates 11. The urinary catheter 1 and the temperature and pressure measuring tube 3 are respectively located between the opposite surfaces of the flexible metal arc plates 13 on the left and right sides of the top of the two positioning base plates 11.

[0024] The working principle of the disposable temperature and pressure measuring catheter will be described in detail below.

[0025] like Figure 1-5As shown, when the urinary catheter 1 is used, the rotating blocks 63 on the left and right sides of the three fixing rings 61 on the outer wall thereof are rotated until the adhesive layer 641 below the positioning belt 64 faces the patient's skin, and then the protective paper 642 at the bottom of the adhesive layer 641 is torn off by pulling the extension paper 643, so that the entire positioning belt 64 is fixed to the patient's skin by the adhesive layer 641, so that the urinary catheter positioning mechanism 6 completes the fixation of the urinary catheter 1, so that the urinary catheter 1 is stably adhered to the patient's skin to prevent bending, and then one end of the input end of the urine bag connecting tube 4 is inserted into the front end inner cavity of the urinary catheter 1, and the temperature and pressure measurement data sensor of the monitor is connected. The wire is inserted into the front end of the temperature and pressure measuring tube 3, and then the fastening rotating plate 133 on the right side of the metal vertical plate 131 extending on the right side of the outer wall of the front end of the catheter 1 and the temperature and pressure measuring tube 3 is rotated at the same time, so as to utilize the threaded connection with the threaded rod 132 and the right side extending metal vertical plate 131, so that the right side extending metal vertical plate 131 drives the bendable flexible metal arc plate 13 to clamp the catheter 1 and the temperature and pressure measuring tube 3 between the two flexible metal arc plates 13, so that the catheter 1 and the temperature and pressure measuring tube 3 are firmly attached to the urine bag connecting tube 4 and the temperature and pressure measuring sensor wire 5 inserted into the inner circle of the catheter 1 and the temperature and pressure measuring tube 3 to complete the reinforcement.
