Description

Three-cavity catheter for removing bladder blood clots

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a clear away three chamber catheters for bladder clot.

Background

The urinary catheter is a common instrument for urinary surgery, and has the main functions of catheterization and bladder irrigation. However, in the practical clinical work, the defects that the current common catheter is easy to block (blood clots, stones or bladder mucosa), difficult to wash, serious in bladder irritation symptom and the like are found, so that the patient can feel uncomfortable, and meanwhile, the trouble is brought to a clinician.

At present, the catheter is designed to have one to two right-angled side holes at the tail end, the diameter of the hole diameter is small, and the design can cause blood clot blockage and difficult flushing; the tail end of the catheter is made of solid rubber, is relatively sharp and hard, and has large irritation to the bladder; when the catheter is pulled out, the water sac is easy to form folds which protrude out of the catheter body part, so that the friction force is increased, and even the water sac is embedded in the external orifice of the urethra when the catheter is pulled out, so that the pain and the discomfort are caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: in order to overcome the defects in the prior art, the utility model provides a three-cavity catheter for removing the bladder blood clots.

The utility model provides a technical scheme that its technical problem will adopt is: a three-cavity catheter for removing bladder clots comprises a catheter body, a head, a balloon and a screen, wherein the head, the balloon and the screen are arranged on the catheter body, a flushing hole, a drainage hole and a water injection hole are formed in the tail of the catheter body, the head is arranged at the front end of the catheter body and comprises a spherical structure and an inserting part protruding out of the spherical structure, the inserting part extends towards the direction away from the catheter body, a round corner is formed in the front end of the inserting part, the inserting part and the spherical structure are in smooth transition, the balloon is arranged on one side, close to the head, of the catheter body, the matching part of the catheter body and the balloon is sunken towards the inside of the catheter body along the circumferential direction, the balloon and the catheter body are hermetically connected, a water injection channel for communicating the balloon and the water injection hole is formed in the catheter body, a circle of the screen is arranged on the catheter body between the head and the balloon, and a flushing channel for communicating the through hole with the flushing hole is arranged in the pipe body.

The insertion part is matched with the spherical structure to form a streamline structure like a dolphin head part, so that the stimulation to bladder mucosa in the insertion process of the catheter is effectively reduced, the resistance in the insertion process of the catheter is reduced, the urethral injury and false tract formation are avoided, and the discomfort of a patient is reduced; the negative pressure device can cut the blood clot into small blocks in the process of sucking the blood clot through the drainage channel, so that the blood clot is prevented from blocking a tube cavity, drainage is facilitated, and the negative pressure device has more advantages particularly when the blood clot in the bladder is flushed; the tube body matched with the saccule is partially recessed, the saccule is a thin layer, when the saccule is not filled with water or air, the saccule is recessed along with the tube body matched with the saccule, so that the saccule can be retracted during recovery, the friction between folds of the water sac and urethra is reduced, and the discomfort caused by the process of removing the urethral catheterization is reduced; after the catheter is inserted into the bladder, water or gas is injected into the balloon through the water injection channel by the water injection device or the gas injection device, so that the balloon is expanded and swollen, the catheter can be prevented from sliding off, and the medium in the balloon is discharged to be taken out or replaced according to the requirement; the flushing channel is matched with the through hole to flush the bladder.

Furthermore, the screen is made of metal alloy. The stress surface of the metal material is small, and the blood clot can be cut more effectively to be in a small block shape in the negative pressure suction blood clot process.

Further, the balloon and the pipe body part matched with the balloon are both made of rubber materials. The inner wall is sunken, which is beneficial to the retraction of the saccule during the recovery, reduces the friction between the saccule plica and the urethra and reduces the discomfort caused by the removal of the urethral catheterization process.

Furthermore, the head is made of smooth silica gel. The smooth design can effectively reduce the stimulation of the end of the catheter to the bladder mucosa, reduce the resistance in the process of inserting the catheter, avoid the urethral injury and the formation of false tracts, and reduce the discomfort of patients.

Further, the angle between the part of the pipe body, which is arranged between the head and the screen, and the screen is 130-140 degrees.

The utility model has the advantages that: the utility model provides a pair of clear away three chamber catheters for bladder clot adopts to set up the head on the catheter and reduces the resistance of inserting the catheter in-process, and metal mesh effectively solves the problem that the clot blockked up the catheter, and the sacculus that can adduct reduces the friction of sacculus plica and urethra, reduces to pull out the discomfort that the catheterization process leads to.
