Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a safety-type guide steel core urinary catheter set. Background Art

[0002] A urinary catheter is a tube inserted through the urethra into the bladder to drain urine. Made of natural rubber, silicone rubber, or polyvinyl chloride (PVC), it is guided through the physiological curvature of the male patient's urethra by a steel guide core. Once inserted, a balloon near the tip of the catheter secures the catheter in place, preventing it from coming out. The catheter is then connected to a urine bag to collect urine.

[0003] The catheter port of an ordinary silicone urinary catheter is located at the front end of the catheter, and the opening direction of the urine outlet is along the forward direction of the guide steel core, which makes it easy for the guide steel core to extend from the urine outlet and cause damage to the urethra. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned problems and shortcomings and to propose a safe guide steel core urinary catheter set: the opening direction of the urine outlet in the silicone head is opposite to the forward direction of the guide steel core, and the position of the urine outlet is at a certain distance from the end of the silicone head cavity, thereby ensuring normal drainage of urine and preventing the guide steel core from passing through the urine outlet and damaging the urethra or bladder, thereby solving the problem of the guide steel core extending from the urine outlet and damaging the urethra or bladder.

[0010] Furthermore, a guiding steel core is slidably connected inside the urinary catheter, and one end of the guiding steel core is in contact with the cavity of the silicone head.

[0011] Furthermore, the guide steel core is provided with a curved arc at one end close to the silicone head.

[0012] Furthermore, one end of the guiding steel core close to the silicone head is treated with a blunt spherical surface to avoid puncturing the catheter.

[0013] Furthermore, a bell-mouth plug is provided at the end of the guide steel core.

[0014] The beneficial effects of the utility model are:

[0015] 1. The distal end of the silicone tube of the utility model reserves a fixed cavity for the end of the guide steel core, and the direction of the opening of the distal catheterization port of the silicone tube is opposite to the forward direction of the guide steel core. The position of the urine outlet is at a certain distance from the end of the silicone head cavity, ensuring the normal drainage of urine and preventing the guide steel core from passing through the urine outlet and damaging the urethra, prostate or bladder.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example:

[0024] Reference Figure 1-4The present utility model discloses a safe guide steel core urinary catheter set, comprising a silicone tube 1 and a guide steel core 7. A silicone head 2 is connected to one end of the silicone tube 1, and a cavity is formed in the silicone head 2 near the center of one end of the silicone tube 1. Urine outlets 3 are formed on the outer wall of the silicone head 2 at equal intervals, and a balloon 4 is provided on the outer wall of one end of the silicone tube 1. An extension tube 5 is connected to the outer wall of one side of the other end of the silicone tube 1, and a urinary catheter 6 is connected to the interior of the silicone tube 1. Preferably, the opening direction of the urine outlet 3 is opposite to the forward direction of the guide steel core 7, and the opening position of the urine outlet 3 is at a certain distance from the end of the cavity of the silicone head 2, thereby ensuring normal urine drainage and preventing the guide steel core 7 from passing through the urine outlet 3 and damaging the urethra or bladder.

[0025] Preferably, the gap between the inner wall of the silicone tube 1 and the outer wall of the urinary catheter 6 is connected to the extension tube 5 and the balloon 4 .

[0026] Preferably, the urine outlet 3 in the silicone head 2 is obliquely opened on the silicone head 2 .

[0027] Furthermore, a water bag injection valve 9 is installed at one end of the extension tube 5, and a plug 10 is screwed on the end of the extension tube 5. After opening the water bag injection valve 9, the gap between the silicone tube 1 and the urinary catheter 6 is inflated through the extension tube 5. The gas pushes the balloon 4 to deform at the balloon 4, thereby fixing the silicone tube 1 inside the bladder.

[0028] The interior of the catheter 6 is slidably connected to the guide steel core 7, and one end of the guide steel core 7 is in contact with the cavity of the silicone head 2. The guide steel core 7 is inserted from the catheter 6 into the cavity of the silicone head 2, and then the silicone tube 1 and the silicone head 2 are inserted into the patient's body. The guide steel core 7 gives the silicone tube 1 a certain strength and makes the soft silicone tube 1 have a certain support, thereby preventing the silicone tube 1 from curling in the urethra, causing catheterization failure or accidentally entering the urethral false passage to damage the urethra.

[0029] Preferably, the guiding steel core 7 is set to a certain curvature near one end of the silicone head 2, and the curvature of the guiding steel core 7 can be manually corrected. By setting the guiding steel core 7, the silicone tube 1 can be correctly guided to smoothly enter the urethra and the physiological curvature of the prostate.

[0030] Preferably, the guide steel core 7 is treated with a blunt spherical surface near one end of the silicone head 2 to prevent the guide steel core 7 from piercing the catheter 6. Preferably, the silicone head 2 is tougher than the catheter 6, and the guide steel core 7 is not easy to puncture the silicone head 2.

[0031] Furthermore, a bell-mouth plug 8 is provided at the end of the guide steel core 7. By providing the bell-mouth plug 8, the guide steel core 7 can be fixed to the end of the silicone tube 1 to prevent the front end of the guide steel core 7 from breaking through the head end of the puncture catheter 6.

[0032] The working principle of the present invention is as follows: when in use, first insert the guiding steel core 7 from the urinary catheter 6 into the cavity of the silicone head 2, and then penetrate the silicone tube 1 and the silicone head 2 into the patient's body. The guiding steel core 7 makes the silicone tube 1 have a certain strength, which is convenient for the silicone tube 1 to move into the patient's body. The opening direction of the urine outlet 3 in the silicone head 2 is opposite to the forward direction of the guiding steel core 7, and the position of the urine outlet 3 is at a certain distance from the end of the cavity of the silicone head 2, ensuring the normal drainage of urine and preventing the guiding steel core 7 from passing through the urine outlet 3, so as to prevent the guiding steel core 7 from damaging the urethra or bladder. After reaching the position, the water bag injection valve 9 is opened, and the space between the silicone tube 1 and the urinary catheter 6 is inflated through the extension tube 5. The gas pushes the balloon 4 to deform at the balloon 4, fixing the silicone tube 1 inside the bladder. The balloon 4 is located at the position of the bladder and urethra, blocking the urethra, so that urine is discharged from the urine outlet 3 and the urinary catheter 6.

However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various combinations of the various technical features and structures proposed in the present invention can be made without exceeding the scope of protection of the present invention, which is determined by the appended claims.
