Description

Auxiliary small part for placing catheter

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a supplementary smallclothes is put into to catheter.

Background

With the increasing severity of social aging, the population of old men is more and more, and prostatic hyperplasia is a common disease of old men, which can cause the bladder neck of a patient to be raised, the posterior urethra to be narrow, the urethra to be lengthened and narrowed and to be bent, and the clinical manifestations of the prostatic hyperplasia are that the urinary bladder is difficult to urinate autonomously, even acute urine retention occurs, that is, a large amount of urine accumulated in the bladder cannot be discharged, and the acute urine retention can cause the serious discomfort of the patient and the damage of the function of the upper urinary tract.

Catheterization is one of the most common clinical treatment methods, and means that a catheter is inserted into the bladder through the urethra to drain the urine in the bladder, and most of the catheters generally used in clinical practice are made of rubber or silica gel. Indwelling catheters are generally used clinically to drain urine in the bladder of a patient to treat acute urinary retention, but because the patient's urethra becomes long, narrow and bends, and the catheters themselves are flexible, it is difficult for the flexible catheter to pass through the deformed, narrowed urethra to smoothly enter the bladder during insertion, and at the same time, the risk of urethral mucosal injury is increased by the catheter rubbing against the deformed, narrowed urethra during insertion.

Aiming at the problem that the catheter is difficult to insert, the ureteral catheter is clinically placed into the catheter at present, the hardness of the ureteral catheter is increased to resist deformation and narrow urethra, so that the catheter can be smoothly placed into a bladder, however, the ureteral catheter used clinically is far longer than the catheter, after the ureteral catheter is placed into the ureteral catheter, the tail end of the catheter cannot be directly connected with a drainage bag, a large amount of urine collected in the bladder of a patient often gushes out at the moment when the catheter enters the bladder, clothes, bedsheets and the like of the patient are directly soaked, the risk of pollution of medical staff is increased, and meanwhile, serious discomfort of the patient is increased.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, an object of the utility model is to provide an auxiliary gadget is put into to the catheter, aim at solving and use ureter pipe to put into the catheter at present clinically and help in the catheter and go up the unable lug connection drainage bag of end of catheter when the catheter, lead to the catheter to get into the patient's bladder in the twinkling of an eye, urine gushes out in the bladder and drenches patient's clothing and sheet, increases the contaminated risk of medical personnel, reduces the problem of patient's satisfaction of seeking medical advice.

The utility model adopts the following technical scheme:

supplementary smallclothes are put into to the catheter includes ureteral catheter, catheter and drainage bag, there is the horn mouth at the catheter end, and packs in the stopper that has the form matching, the head end of catheter is one section diversion district, the lateral wall of diversion district is opened has at least one water conservancy diversion hole, the head end of ureteral catheter passes the stopper until entering catheter diversion district, the end grafting of ureteral catheter has the joint, be provided with adjust knob on the joint, the joint end with the terminal shape of catheter is the same, the drainage bag is including the socket stopper, the drainage tube and the urine bag of connecting in order, the socket stopper is packed in the joint is terminal.

Further, the joint middle section is hard pipe and has opened a plurality of windows along length direction symmetry, adjust knob installs on the hard pipe, the adjust knob inner wall be provided with the circular arc wedge of window one-to-one, the head end of circular arc wedge penetrates the window that corresponds and leans on the window side.

Further, the catheter is provided with an air bag near the diversion area, the inner side wall of the catheter is provided with an air bag channel communicated to the air bag, and the side wall of the catheter is further provided with a capsule body interface communicated with the air bag channel.

The utility model has the advantages that: the utility model provides an auxiliary small part is put into to the catheter, through putting into ureter pipe in the catheter, stopper on the terminal plug of catheter to through connecting ureter pipe and drainage bag intercommunication, can effectively avoid appearing inserting the condition that the sheet was drenched in the urine blowout in the twinkling of an eye of catheter, this device has simple structure, convenient to use's characteristics.
