Description

Urinary catheter

Technical Field

The utility model relates to the field of medical supplies, especially, relate to a ureter.

Background

A urinary catheter, also known as a urinary catheter, is a conduit that is inserted into the bladder from the urethra to drain urine.

In the urinary catheter drainage process, a continuous drainage mode is adopted most of the time, namely, the urinary catheter is kept smooth for a long time. But the urinary catheter pinch exercise is usually performed two to three days before withdrawal to exercise bladder function. The practice of clamping and closing the ureter refers to clamping and closing the ureter, opening the ureter for one time for two to three hours to urinate, and then clamping and closing the ureter, wherein the clamping and opening period of the ureter is the same as the urination period of a normal person. The practice of clamping and closing urinary catheters is documented in various documents, such as ' influence of different methods for clamping and closing urinary catheters on the recovery of bladder functions ' in ' journal of practical neurological diseases of China (010) stage 009 ' in ' 2019(005) stage 001 ' discussion on the necessity of clamping and closing urinary catheters before indwelling catheter extubation '.

As mentioned above, the practice of clamping and closing the urinary catheter requires opening the urinary catheter at regular time and the nurse to remember the opening time of the urinary catheter. However, in clinical practice, the condition that a nurse forgets to open the urinary catheter due to a large number of patients in a hospital and busy work is inevitable, so that the patient is uncomfortable due to too much urine, the bladder exercise effect is affected, and the bladder and other human organs can be damaged. And different patients have different water drinking conditions, the urine accumulated in the same time is different, and if the urine is accumulated in a sufficient amount and the time is short, the ureter is not opened, the problems are also caused.

Numerous urinary catheter patents, such as ZL201420587961.2, ZL200920315399.7, ZL201220546864.x, all disclose urinary catheters. The applicant has not found a urinary catheter which solves the above problems.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a can close at the ureter, hold back when too much urine and open automatically, discharge the ureter of some urine.

The technical scheme adopted for solving the problems is as follows: the ureter includes the body, and the body includes body anterior segment, body back end, first branch pipe and second branch pipe, and first branch pipe and second branch pipe all are located between body anterior segment and the body back end, and first branch pipe and second branch pipe all communicate with body anterior segment and body back end, are provided with the switch on the first branch pipe, are provided with first valve in the second branch pipe, and first valve can open towards the body back end when urine pressure reaches the setting value.

Further, the method comprises the following steps: the second valve is arranged in the rear section of the tube body and can prevent urine in the tube body from flowing backwards.

Further, the method comprises the following steps: the switch is a flow stopping clip.

The utility model has the advantages that: 1. the opening pressure of the first valve is set according to the upper safe bladder pressure limit. When the ureter is clamped and closed for exercise, the switch is closed, namely the first branch pipe is closed. If the bladder pressure reaches the upper limit of the safe bladder pressure when the switch is not opened, the first valve is opened to discharge part of urine, so that the bladder pressure is prevented from exceeding the upper limit of the safe pressure, and the discomfort of a patient and the damage to the bladder and other human organs are avoided. When the bladder pressure does not reach the safe upper limit, the first valve is not opened, and the effect of the urinary catheter clamping exercise cannot be influenced.

2. The utility model discloses simple structure to the ureter cost is obviously not increased, the practicality is strong.

FIG. 2 is an enlarged partial view of the urinary catheter;

FIG. 3 is a view of a first valve configuration;

labeled as: the valve body comprises a body 1, a body front section 11, a body rear section 12, a first branch pipe 13, a second branch pipe 14, a switch 15, a first valve 16 and a second valve 17.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the ureter includes a catheter body 1, the catheter body 1 includes a catheter body front section 11, a catheter body rear section 12, a first branch pipe 13 and a second branch pipe 14, the first branch pipe 13 and the second branch pipe 14 are both located between the catheter body front section 11 and the catheter body rear section 12, the first branch pipe 13 and the second branch pipe 14 are both communicated with the catheter body front section 11 and the catheter body rear section 12, a switch 15 is arranged on the first branch pipe 13, a first valve 16 is arranged in the second branch pipe 14, and the first valve 16 can be opened towards the catheter body rear section 12 when urine pressure reaches a set value.

The valve is prior art and the first valve 16 is identical in construction to the prior art valve. The valve structure is shown in fig. 2 and 3, and is in the shape of a conical sheet with radial slits, the material of which is elastic. When liquid flows from back to front, namely from the bottom of the valve to the tip, the valve is easy to be opened, namely the opening pressure of the valve in the direction is low; when the liquid flows from front to back, the valve is not easy to be opened, namely the opening pressure of the valve in the direction is larger. The opening pressure of the first valve 16 is set according to the upper bladder safety pressure limit, i.e. preferably 40cm water column pressure. The tip of the first valve 16 should face the front segment 11 of the tube body, and can be opened to meet the requirement by controlling the parameters such as the material size and the like.

During the practice of clamping the catheter closed, the switch 15 is closed, i.e. the first branch line 13 is closed. If the bladder pressure reaches the upper safe bladder pressure limit when the switch 15 is not opened, the first valve 16 is opened to discharge part of urine from the second branch pipe 14, so as to prevent the bladder pressure from exceeding the upper safe pressure limit, and further prevent the patient from discomfort and damage to the bladder and other human organs. When the bladder pressure does not reach the safe upper limit, the first valve 16 is not opened, and the effect of the urinary catheter clamping exercise cannot be influenced. When the urinary catheter continues to drain, the switch 15 is opened and urine passes through the first branch line 13.

The switch 15 may be a flow stop clip. The flow stopping clamp has simple structure and is applied to a plurality of medical pipelines.

When the urinary catheter is used, the rear end of the urinary catheter is connected with a drainage bag to collect the drained urine. When the conventional use of ureter lasts the drainage, the drainage bag position of being connected with the ureter is lower, and the urine does not have the refluence risk usually. However, in some special cases, such as patient transportation, there may be a risk of urine backflow after the drainage bag is elevated. In order to avoid the urine backflow, the second valve 17 is arranged in the rear section 12 of the tube body, and the second valve 17 can prevent the urine backflow in the tube body 1.

The second valve 17 is also the same as the conventional valve, and the tip end of the second valve faces the rear end of the ureter and does not obviously increase the urine outflow resistance; the second valve 17 can prevent the reverse flow of urine since the pressure of the reverse flow of urine is not large.

The utility model discloses simple structure to the ureter cost is obviously not increased, the practicality is strong.
