Description

Anti-drop indwelling catheter

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an anti-falling indwelling catheter.

Background

Currently, the indications for indwelling catheters include: urinary retention, a serious condition requiring strict calculation of urination volume, especially in patients with prolonged operation time or post urinary surgery. Indwelling catheters are the ultimate treatment for urinary incontinence, particularly when incorporated with skin lesions, and pressure sores in the sacral or perineal region. The urinary catheter can be used for short or long periods (> 30 days) depending on the indication. If a long-term drainage tube placement in the bladder is desired, the intermittent self-catheterization method (CISC) is better than the indwelling catheter method, but the CISC method may not be used in all cases.

Indwelling catheterization is one of the most basic nursing operations in clinic, and aims to drain urine, accurately record urine volume, perform urinary system related examination, prevent accidental injury during operation, reduce incision tension after operation, and keep perineum dry after urinary system operation. Catheter related urinary tract infection (cauti) refers to infection occurring during catheter retention or within 48 hours after catheter removal, and has occurrence rate which is inferior to pulmonary infection, is one of the most common infection types in hospital infection, and is mainly retrograde infection caused by the catheter. In the "severe intensive care unit hospital infection control Specification" which is started to be implemented in 2017, month 06 and 01, it is proposed that: 1. the tightness of the urine drainage system should be maintained; 2. when the urine specimen is collected for microorganism detection, the urine is needled and extracted on the side surface of the catheter by a sterile method. Thus, there is an urgent need for a fully functional indwelling catheter for clinical use.

Detailed Description

The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown.

As shown in fig. 1, an anti-falling indwelling catheter comprises a catheter body 1, a front section head 2 for guiding the catheter body 1 to penetrate into the urethra is arranged at the front part of the catheter body, a flat balloon 3 is arranged at the outer side of the front section head 2, the flat balloon 3 is connected with an inflation head 4 through an inflation tube, the flat balloon 3 can be inflated and supported by inflation or saline injection, a liquid discharge hole 5 and a flushing hole 6 are arranged at one end, different from the front section head 2, of the catheter body 1, and two sealing plugs are arranged at the rear end of the catheter body 1 and used for sealing the flushing hole 6 and the liquid discharge hole 5. One or two stainless steel wires are arranged at the ring pipe body position inside the front section head 2, two rows of side grooves 7 with the width of 1mm and the length of 5mm are arranged at the position, which is 10mm away from the pipe tip, of the front section head 1, and the edges of the side grooves 7 are of a rounding structure. The catheter body formed by the front section head 2 and the catheter body 1 is of a cone structure, the front end is narrow, the front end is enlarged backwards, and the gradual change angle is 2 degrees. The catheter body 1 is internally provided with a unidirectional diaphragm 8. The edge of the flat balloon 3 is provided with an inflatable ear 9, and the ear 9 is communicated with the flat balloon 3. The catheter body 1 is provided with a fixing clip 10 with a buckle at the liquid discharge hole 5. The catheter body 1 is internally provided with a steel wire rope. The catheter body 1 is made of polyurethane.

The following are specific examples of the utility model

As shown in figure 1, the inner ring tube body of the front end head 2 of the catheter body 1 is internally provided with one or two stainless steel wires, so that the head is harder and is easier to penetrate into the urethra, and because the stainless steel wires are internally provided, the infection and inflammation caused by metal can not be caused. Thus, the head end is harder, which is convenient for doctors or nurses to operate better, and can save operation time. The steel wire rope arranged in the catheter body 1 is soft, so that discomfort of a patient caused by an excessively hard head end in the later catheterization is prevented;

as shown in fig. 2, the front section head 1 is provided with 2 rows of side grooves 7 with the width of 1mm and the length of 5mm around the position 10mm away from the tip of the tube, the edges of the side grooves 7 are rounded, so that urine can be discharged more smoothly and effectively, and when a front end hole is prevented from being blocked, the side grooves 7 can also drain urine;

as shown in fig. 2, the whole tube body is of a conical structure, the front end is narrow, then the front end is gradually enlarged, the gradual change angle is 2 degrees, and the angle is slightly changed, so that discomfort and pain of a patient can be relieved when the tube is placed;

the whole pipe body is made of polyurethane, so that the flexibility is improved, the polyurethane is soft, bending and blocking are prevented, and the position of the liquid discharge hole 5 is coated with silver, so that an antibacterial effect can be achieved;

the inside of the tube body is provided with a diaphragm 8 which can effectively prevent bacteria from invading through the liquid discharge hole 5;

the diaphragm 8 is a one-way valve, and the valve can be opened in one direction by the pressure of the urine in the bladder, so that bacteria at the pipeline port can be effectively prevented from being brought in when the patient pipeline is injected with the mixture of sodium bicarbonate and physiological saline for cleaning;

the edge of the flat balloon 3 is provided with an inflatable ear 9 (which is suitable for the situation that a part of old women easily fall off due to vaginal relaxation), when 10ml of normal saline is injected, the middle part just props up, and a common patient can fix the balloon. 15ml of physiological saline can be injected into a part of special old people, so that ears on the edges are just supported, the contact area is increased to fix the catheter, and the catheter can be prevented from falling off the patient;

at the joint of the existing clinical catheter and the drainage bag, the urine is easy to fall off due to the turning over of a patient and the like, and the urine is sprayed on the bed. Such joints are currently on the market typically around 15N. As shown in fig. 3, the catheter of this embodiment is provided with a fixing clip 10 with a buckle at the rear end drain hole 5, and the fixing clip is forcibly pressed to lock the joint position after the drainage bag is inserted into the catheter. Thus, the strength of 30N can be formed, the drainage bag can be more effectively prevented from falling off, the pain of a patient is relieved, and the time of doctors is saved;

this embodiment has 2 sealing plugs for sealing the flushing and draining holes. When the drainage bag is replaced or the drainage bag is not washed, the pipeline opening can be sealed, and bacteria are effectively prevented from being immersed.

According to the anti-falling indwelling catheter disclosed by the utility model, as the flat balloon capable of being inflated or injecting saline is arranged on the catheter body, the falling of the catheter from the urethra can be avoided, when the front end hole is blocked by the side groove arranged on the front section head, the urine can be dredged by the side hole, the catheter has good tightness, the catheterization can be carried out under the aseptic condition, and the probability of urinary tract infection is greatly reduced.
