Description

Urinary catheter placement aids

technical field

The utility model belongs to the field of medical devices, in particular to an auxiliary small piece for placing a urinary catheter.

Background technique

With the aging of the society, the population of elderly men is increasing, and benign prostatic hyperplasia is a common disease of elderly men. Prostatic hyperplasia will lead to bladder neck elevation, posterior urethra stenosis, and urethra lengthening and narrowing. Curved, clinical manifestations are difficult to urinate spontaneously, and even acute urinary retention occurs, that is, a large amount of urine accumulated in the bladder cannot be excluded.

Urinary catheterization is one of the most common clinical treatment methods. It refers to inserting a catheter into the bladder through the urethra to draw out the urine in the bladder. Most of the catheters commonly used in clinical practice are made of rubber or silicone. . Clinically, an indwelling catheter is usually used to drain the urine in the patient's bladder to treat acute urinary retention. However, because the patient's urethra becomes longer, narrower and curved, the catheter itself is flexible, and the flexible guide is inserted when inserted. It is difficult for the urinary catheter to pass through the deformed and narrowed urethra to enter the bladder smoothly, and the friction between the catheter and the deformed and narrowed urethra during the insertion process will increase the risk of urethral mucosal damage.

In view of the difficulty of inserting the urinary catheter, the ureteral catheter is currently clinically inserted into the urinary catheter to increase the hardness of the urinary catheter to resist the deformation and narrow urethra, so as to facilitate the smooth insertion of the urinary catheter into the bladder. The ureteral catheter used in the above is much longer than the urinary catheter. After the urinary catheter is built into the ureteral catheter, the end of the urinary catheter cannot be directly connected to the drainage bag, which often leads to the moment when the catheter enters the bladder, a large amount of urine accumulates in the patient's bladder. The liquid spewed out and directly soaked the clothes and bed sheets of the patients, which increased the risk of contamination of medical staff, and also increased the serious discomfort of patients.

Utility model content

In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of ureteral catheter placement auxiliary small piece, aims to solve the problem that the end of the ureteral catheter cannot be directly connected to the drainage when the ureteral catheter is used clinically and is inserted into the ureteral catheter to assist the upper urethra When the catheter enters the patient's bladder, the urine in the bladder will wet the patient's clothes and bed sheets, increase the risk of contamination of medical staff, and reduce the patient's satisfaction with medical treatment.

The utility model adopts the following technical solutions:

The urinary catheter insertion auxiliary small piece includes a ureteral catheter, a urinary catheter and a drainage bag, the end of the urinary catheter has a flared mouth, and a plug of matching shape is inserted, and the head end of the urinary catheter is a section. A diversion area, the side wall of the diversion area is provided with at least one diversion hole, the head end of the ureteral catheter passes through the plug until it enters the catheter diversion area, and the end of the ureteral catheter is inserted into the diversion area. A joint is connected, an adjustment knob is provided on the joint, the end of the joint is the same in shape as the end of the catheter, and the drainage bag includes a socket plug, a drainage tube and a urine bag that are connected in sequence, and the socket plug is plugged into the linker end.

Further, the middle section of the joint is a rigid tube with several windows symmetrically opened along the length direction, the adjustment knob is installed on the rigid tube, and the inner wall of the adjustment knob is provided with a circle corresponding to the window one-to-one. An arc wedge, the head end of the arc wedge penetrates the corresponding window and abuts against the side of the window.

Further, the urinary catheter is provided with a balloon near the diversion area, the inner side wall of the urinary catheter is provided with a balloon channel connected to the balloon, and the urinary catheter side wall is also provided with a balloon interface, The balloon interface communicates with the balloon channel.

The beneficial effects of the utility model are as follows: the utility model provides an auxiliary small piece for the insertion of a ureteral catheter. By inserting a ureteral catheter into the ureteral catheter, plugging the end of the ureteral catheter, and connecting the ureteral catheter and the drainage bag through a joint The connection can effectively avoid the situation that the urine is sprayed out to wet the bed sheet when the urinary catheter is inserted, and the device has the characteristics of simple structure and convenient use.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

In order to illustrate the technical solutions of the present utility model, the following specific embodiments are used to illustrate.

FIG. 1 shows the structure of a small auxiliary component for placing a urinary catheter provided by an embodiment of the present invention, and only shows the parts related to the embodiment of the present invention for the convenience of description.

As shown in FIG. 1 , the urinary catheter placement auxiliary component provided in this embodiment includes a ureteral catheter 1, a urinary catheter 2 and a drainage bag. The drainage bag includes a socket plug 8, a drainage tube 9 and a drainage bag connected in sequence. The urine bag 10 has a flared mouth at the end of the catheter and is inserted with a plug 3 that matches the shape. The diversion hole 5, the head end of the ureteral catheter passes through the plug until it enters the catheter drainage area, the end of the ureteral catheter is inserted with a joint 6, and the joint is provided with an adjustment knob 7, The connector end has the same shape as the catheter end, and the socket plug is inserted into the connector end.

When in use, pass the head end of the ureteral catheter through the plug until it is inserted into the drainage area of the catheter, and then plug the plug into the end of the catheter. Thereby, the ureteral catheter is fixed to prevent it from sliding inward or outward, the end of the ureteral catheter is connected to the joint, the adjusting knob is rotated, the joint is clamped to the ureteral catheter, and the end of the joint is connected to the drainage bag. When in use, insert the head end of the catheter into the user's bladder, and the urine in the patient's bladder enters the catheter drainage area through the diversion hole, and then is transported to the drainage bag through the ureteral catheter to complete urination. When the urine in the bladder is completely drained, loosen the plug, remove the drainage bag from the connector, and then take out the ureteral catheter and discard it. At this time, the plug of the drainage bag can be directly connected to the end of the catheter without the aid of the adapter. .

The ureteral catheter insertion auxiliary small piece provided by the utility model can effectively avoid the occurrence of ureteral catheter insertion by inserting the ureteral catheter into the catheter, plugging the end of the catheter with a plug, and connecting the ureteral catheter and the drainage bag through a joint.
