Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a urinary catheter structure with an airbag. Background Art

[0002] A urinary catheter is a tube inserted into the bladder through the urethra for urine drainage. It is made of natural rubber, silicone rubber or polyvinyl chloride. When removing the urinary catheter, the normal saline in the airbag is pumped out, resulting in the wrinkling of the airbag. To prevent the wrinkled airbag from irritating the urethral mucosa, 0.5 mL of normal saline needs to be injected into the airbag after pumping out the normal saline in the urinary catheter. The normal saline flushes up the airbag to make its surface smooth, preventing the wrinkled airbag from rubbing against the urethral wall and increasing the patient's pain. This increases the nurse's operation steps, thus increasing the workload and reducing the speed of removing the urinary catheter. Therefore, a new type of urinary catheter structure with an airbag is designed to solve the above technical defects. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a urinary catheter structure with an airbag, which aims to solve the technical problems that after pumping out the normal saline when removing the urinary catheter, 0.5 mL of normal saline needs to be injected into the airbag to lift the airbag to make its surface smooth, preventing the wrinkled airbag from rubbing against the urethral wall and increasing the patient's pain, increasing the nurse's operation steps, thus increasing the workload and reducing the speed of removing the urinary catheter.

[0005] (2) Technical Solutions

[0006] To solve the above technical problems, the utility model provides such a urinary catheter structure with an airbag. The urinary catheter structure includes a urinary catheter body. A hose connector is installed at the left end of the urinary catheter body. An air groove is formed on the outer surface of the urinary catheter body. A positioning airbag is fixedly connected to the inner wall of the air groove. An air duct is formed inside the urinary catheter body, and the air duct is communicated with the air groove. An airbag connector is fixedly connected to the outer surface of the urinary catheter body, and the airbag connector is communicated with the air duct. A drainage hole is formed on the outer surface of the urinary catheter body. A retention mechanism is installed inside the air duct. The retention mechanism includes a telescopic tube. The telescopic tube is slidably installed inside the air duct, and the left end of the telescopic tube is fixedly connected to the inner wall of the air duct through a rubber band. The right end of the telescopic tube is fixedly connected to the inner wall of the positioning airbag through a traction rope. Through holes are formed on the outer surface of the telescopic tube. The urinary catheter body is made of silicone rubber or natural rubber.

[0007] When using the urinary catheter of this technical solution, the right end of the catheter body is inserted into the patient's bladder through the patient's urethra. Medical staff use a syringe to connect with the airbag connector and inject normal saline into the airway. The normal saline pushes the telescopic tube into the air groove. When the through holes on the surface of the telescopic tube enter the air groove, the normal saline enters the air groove through the through holes, causing the positioning airbag to expand. The positioning airbag contacts the inner wall of the bladder for fixation. While the positioning airbag expands, it pulls the traction rope to drive the telescopic tube to move. The movement of the telescopic tube makes the rubber band in a stretched state. When the urinary catheter needs to be removed, the airbag connector is opened, and a syringe is installed to suck out the normal saline through the airway. The normal saline in the positioning airbag enters the telescopic tube through the through holes and is discharged from the airway. The reduction of the normal saline in the positioning airbag causes it to contract, reducing its pulling force on the traction rope. Under the action of the elastic force of the rubber band, the telescopic tube is pulled into the airway. When the remaining normal saline in the positioning airbag is 0.5 mL, the telescopic tube completely enters the airway. At this time, the through holes contact the inner wall of the airway to prevent the normal saline in the positioning airbag from being discharged, realizing the quantitative retention of normal saline in the positioning airbag to support the positioning airbag and prevent the positioning airbag from wrinkling. There is no need to inject normal saline into the positioning airbag for the second time, reducing the workload of medical staff, and solving the technical problems that after the normal saline is drawn out during the traditional removal of the urinary catheter, 0.5 mL of normal saline needs to be injected into the airbag again to lift the airbag to make its surface smooth, prevent the airbag from wrinkling and scratching the urethral wall, increasing the pain of the patient, increasing the operation steps of nurses, thus increasing the workload, and reducing the speed of removing the urinary catheter.

[0008] Preferably, a sealing pad is fixedly connected to the outer surface of the telescopic tube near the traction rope end. Through the setting of the sealing pad, the sealing effect on the airway is enhanced, preventing normal saline from leaking out from the gap between the telescopic tube and the airway when the telescopic tube is located in the airway.

[0009] Furthermore, a conical head is installed at the right end of the catheter body. Through the setting of the conical head, the forward resistance of the catheter body in the urethra is reduced, facilitating the installation of the catheter.

[0010] Even further, scale grooves are provided on the outer surface of the catheter body. Through the setting of the scale grooves, the insertion depth of the catheter body can be known by observing the scales. Medical staff can know the insertion depth based on the currently displayed scales, so as to clearly know whether one end of the catheter body has been inserted into the bladder.

[0011] (3) Beneficial effects

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the right end of the urinary catheter body is inserted into the patient's bladder through the urethra. Medical staff use a syringe to connect with the airbag connector and inject physiological saline into the airway. The physiological saline pushes the telescopic tube into the air groove. When the through holes on the surface of the telescopic tube enter the air groove, the physiological saline passes through the through holes into the air groove to inflate the positioning airbag. The positioning airbag contacts the inner wall of the bladder for fixation. While the positioning airbag inflates, it pulls the traction rope to drive the telescopic tube to move. The movement of the telescopic tube stretches the rubber band. When it is necessary to remove the urinary catheter, the airbag connector is opened, a syringe is installed, and the physiological saline is pumped out through the airway. The physiological saline in the positioning airbag enters the telescopic tube through the through holes and is discharged from the airway. The reduction of the physiological saline in the positioning airbag causes it to contract, reducing its pulling force. Under the action of the elastic force of the rubber band, the telescopic tube is pulled into the airway. When the remaining physiological saline in the positioning airbag is 0.5 mL, the telescopic tube completely enters the airway. At this time, the through holes contact the inner wall of the airway to prevent the discharge of the physiological saline in the positioning airbag, realizing the quantitative retention of the physiological saline in the positioning airbag to support the positioning airbag and prevent the positioning airbag from wrinkling. There is no need to inject physiological saline into the positioning airbag again, reducing the workload of medical staff, and solving the technical problems that after the physiological saline is pumped out during the traditional removal of the urinary catheter, 0.5 mL of physiological saline needs to be injected into the airbag again to lift the airbag to make its surface smooth, prevent the airbag from wrinkling and rubbing against the urethral wall to increase the patient's pain, increase the operation steps of nurses, thus increasing the workload, and reducing the speed of removing the urinary catheter.

Specific Embodiment

[0021] This specific embodiment is a urinary catheter structure with an airbag, and its structural schematic diagram is as follows Figures 1-6 shown. A urinary catheter structure with an airbag, the urinary catheter includes a catheter body 3, a hose connector 1 is installed at the left end of the catheter body 3, an air groove 9 is formed on the outer surface of the catheter body 3, a positioning airbag 5 is fixedly connected to the inner wall of the air groove 9, an air passage 10 is formed inside the catheter body 3, and the air passage 10 communicates with the air groove 9. An airbag connector 2 is fixedly connected to the outer surface of the catheter body 3, and the airbag connector 2 communicates with the air passage 10. Drainage holes 6 are formed on the outer surface of the catheter body 3. A retention mechanism is installed inside the air passage 10. The retention mechanism includes a telescopic tube 12. The telescopic tube 12 is slidably installed inside the air passage 10, and the left end of the telescopic tube 12 is fixedly connected to the inner wall of the air passage 10 through an elastic band 11. The right end of the telescopic tube 12 is fixedly connected to the inner wall of the positioning airbag 5 through a traction rope 14. Through holes 13 are formed on the outer surface of the telescopic tube 12. The catheter body 3 is made of silicone rubber or natural rubber.

[0022] Among them, a sealing pad 8 is fixedly connected to the outer surface of the telescopic tube 12 near the traction rope 14. Through the arrangement of the sealing pad 8, the sealing effect on the air passage 10 is increased, preventing physiological saline from leaking out from the gap between the telescopic tube 12 and the air passage 10 when the telescopic tube 12 is located in the air passage 10. A tapered head 7 is installed at the right end of the catheter body 3. Through the arrangement of the tapered head 7, the forward resistance of the catheter body 3 in the urethra is reduced, facilitating the installation of the urinary catheter.

[0023] In addition, a scale groove 4 is formed on the outer surface of the catheter body 3. Through the arrangement of the scale groove 4, the insertion depth of the catheter body 3 can be known by observing the scale. Medical staff can know the insertion depth based on the currently displayed scale, so as to clearly know whether one end of the catheter body 3 is inserted into the bladder.

[0024] Working principle: When using the urinary catheter of this technical solution, the right end of the catheter body 3 is inserted into the patient's bladder through the patient's urethra. Medical staff connect a syringe to the airbag connector 2 and inject physiological saline into the air passage 10. The physiological saline pushes the telescopic tube 12 into the air groove 9. When the through hole 13 on the surface of the telescopic tube 12 enters the air groove 9, the physiological saline passes through the through hole 13 into the air groove 9 to inflate the positioning airbag 5. The positioning airbag 5 contacts the inner wall of the bladder for fixation. While the positioning airbag 5 inflates, it pulls the traction rope 14 to drive the telescopic tube 12 to move. The movement of the telescopic tube 12 makes the rubber band 11 in a stretched state. When the urinary catheter needs to be removed, the airbag connector 2 is opened and a syringe is installed to draw out the physiological saline through the air passage 10. The physiological saline in the positioning airbag 5 enters the telescopic tube 12 through the through hole 13 and is discharged from the air passage 10. The physiological saline in the positioning airbag 5 decreases and contracts, reducing its pulling force. Under the elastic force of the rubber band 11, the telescopic tube 12 is pulled into the air passage 10. When the remaining physiological saline in the positioning airbag 5 is 0.5 mL, the telescopic tube 12 completely enters the air passage 10. At this time, the through hole 13 contacts the inner wall of the air passage 10 to prevent the physiological saline in the positioning airbag 5 from being discharged, realizing the quantitative retention of physiological saline in the positioning airbag 5 to support the positioning airbag 5 and prevent the positioning airbag 5 from wrinkling. There is no need to inject physiological saline into the positioning airbag 5 again, reducing the workload of medical staff, and solving the technical problems that after the physiological saline is drawn out during the traditional removal of the urinary catheter, 0.5 mL of physiological saline needs to be injected into the airbag again to lift the airbag to make its surface smooth, prevent the airbag from wrinkling and rubbing against the urethral wall to increase the patient's pain, increase the operation steps of nurses, thereby increasing the workload, and reducing the speed of removing the urinary catheter.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiment is a preferred implementation solution of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
