Description

Urinary Catheters for Urology

technical field

The utility model relates to the technical field of medical auxiliary equipment.

Background technique

At present, when the urology department performs catheterization on patients, it is necessary to lubricate the catheter first. This process is likely to cause cross infection and increase the pain of the patient. Then the lubricated catheter is inserted into the bladder through the urethra and inserted into the designated position, to achieve the purpose of catheterization, but this method is not only complicated to operate, the operation time is long, but also affects the treatment effect on patients. In addition, bleeding or secretions sometimes occur in the catheter, which needs to be cleaned in time to prevent infection. Generally, the catheter needs to be pulled out for cleaning. This repeated intubation method brings great pain to the patient and is very inconvenient. In addition, urine reflux may occur during catheterization, which may easily cause infection and affect the treatment of patients.

The search found that the Chinese patent application with the application number 201521099881.3 discloses a urinary catheter for urology, which can prevent the backflow of urine from causing harm to the patient, but it uses a one-way valve to prevent the backflow of urine. It is easy to cause secretions to block the urinary catheter; the Chinese patent application No. 201520642842.7 is a urinary catheter for urology, which has defects in the way of cleaning the urinary catheter, and the cleaning fluid may enter the patient's body without being cleaned. Recycle as much as possible, causing damage to patients.

For this reason, we disclose a urinary catheter for urology, which can effectively solve the above problems.

To further optimize the technical proposal, scales are provided on both the outer sleeve and the outer wall of the inner catheter of the urological catheter.

To further optimize the technical solution, the side wall of the urine storage bag of the urinary catheter for urology is connected with a detection tube; the detection tube mouth is provided with a rubber cap.

To further optimize the technical proposal, the distance between the front end of the helical shaft of the urinary catheter for urology and the annular fluid storage bag is 1-2mm.

Compared with traditional measuring tools, the utility model has the beneficial effects of:

1. The form of the outer tube socketed with the inner catheter avoids cross-infection to the patient during lubrication, and at the same time reduces the pain caused to the patient when inserting and pulling out the catheter; the semi-elliptical catheter head increases the area of catheterization and passes through the through hole The urine is introduced into the inner casing; the driving motor drives the screw shaft to rotate, and the urine is brought into the urine storage bag through the branch pipe, and effectively prevents the urine from flowing back; the sliding motor seat makes the screw shaft squeeze the annular liquid storage bag, and the liquid outlet hole The cleaning fluid in the annular fluid storage bag can be sprayed out to clean the inner catheter, effectively preventing the occurrence of infection problems.

2. Both the outer wall of the outer cannula and the inner catheter are provided with scales, which can clearly show the length of the outer cannula and inner catheter inserted into the human body.

3. The detection tube is convenient for the doctor to extract the patient's urine for detection, and the rubber cap acts as a seal.

4. There is a distance of 1-2mm between the spiral shaft and the annular liquid storage bag, so as to avoid touching the annular liquid storage bag when the spiral shaft rotates.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 1-3, the urinary catheter for urology includes a cylindrical outer sleeve 1; the outer sleeve 1 is sleeved with an inner catheter 2; the front end of the inner catheter 2 is provided with a semi-elliptical catheter head 3; Several through holes 4 are evenly distributed on the catheter head 3; the inner front end of the inner catheter 2 is provided with an annular liquid storage bag 5; the surface of the annular liquid storage bag 5 is evenly distributed with liquid outlet holes 6; the rear part of the inner catheter 2 is connected There is a vertically downward branch pipe 7; the outlet of the branch pipe 7 is connected with a urine storage bag 8; the middle part of the branch pipe 7 is provided with a one-way valve 9; the rear end of the inner conduit 2 is slidingly sleeved with a motor seat 10; There is a drive motor 11; the output end of the drive motor 11 is connected with a helical shaft 12; the helical shaft 12 extends into the interior of the inner conduit 2 and cooperates with the inner conduit 2 in rotation and sealing; the outer wall of the outer sleeve 1 and the inner conduit 2 is provided with Scale 13; detection tube 14 connected to the side wall of urine storage bag 8; rubber cap 15 is provided at the mouth of detection tube 14; the distance between the front end of the spiral shaft 12 and the annular liquid storage bag 5 is 1-2 mm.

When catheterizing the patient, at first the catheter head 3 and the outer wall of the inner catheter 2 are smeared with lubricating fluid, the inner wall and the outer wall of the outer sleeve 1 are smeared with lubricating fluid, the outer sleeve 1 is set on the outer surface of the inner catheter 2, and the utility model The new type is inserted into the patient's body as a whole. When the length of the outer cannula 1 reaches the requirement, the inner catheter 2 is slowly pushed to make the catheter head 3 slowly reach the patient's bladder. Due to the segmented insertion, it is prevented that the lubricating fluid is consumed in the early stage of insertion, preventing As the insertion continues, the problem of damage to the patient's body due to poor lubrication occurs; the through holes 4 are evenly distributed on the oval catheter head 3 to increase the catheterization efficiency. During catheterization, the driving motor 11 drives the helical shaft 12 to rotate, Pass the urine, bleeding and secretions in the patient's body to the position of the branch pipe 7, and flow into the urine storage bag 8 through the one-way valve 9 to complete the catheterization process; due to the rotation of the screw shaft 12, the urine, bleeding and secretions, etc. It will not flow back into the patient's body, and the helical shaft 12 can effectively prevent the accumulation problem, and will not block the inner catheter 2 with bleeding and secretions; When touching the annular liquid storage bag 5 and cleaning the inner catheter 2, you only need to push the motor base 10 to make the top of the screw shaft 12 squeeze the annular liquid storage bag 5, and the cleaning agent in the annular liquid storage bag 5 will be released from the The liquid outlet hole 6 flows out and rotates through the helical shaft 12 to realize uniform cleaning of the inner catheter 2 without flowing into the patient's body, thereby avoiding the problem of infection to the patient.

Both the outer wall of the outer tube 1 and the inner catheter 2 are provided with a scale 13, which is convenient for medical staff to observe the length of the outer tube 1 and the inner catheter 2 extending into the human body, which increases safety and practicability; the setting of the detection tube 14 enables the doctor to pass through the syringe. The detection tube 14 extends into the urine storage bag 8 to extract the patient's urine for detection, and the rubber cap 15 plays a sealing role, preventing the urine from flowing out from the detection tube 14 in the urine storage bag 8 .
