Problems solved by technology

These diseases require routine indwelling urinary catheters after surgery, and bladder irrigation if necessary. However, because the head of the traditional urinary catheters only has two small side holes, it is difficult to meet the various conditions of different patients, so there are often Blood clots or tissue blocks lead to blockage of the urinary catheter, and severe cases may lead to a second operation, which not only causes great pain to the patient, but also brings a lot of trouble to the medical staff
In addition, the traditional indwelling catheter is clamped at the urine bag outside the body, which is easy to cause retrograde urinary tract infection through urine

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of the present invention, a urinary catheter with an adjustable head opening size, comprising a straight catheter 1, hollow micro-channels arranged at equal intervals in the side wall of the straight catheter 1, and sliding guide wires 2 built in the micro-channels The front end of the straight catheter 1 is provided with a ureteral terminal 3, and a regulating switch 4 that can adjust the telescopic guide wire is provided at the rear section, one end of the sliding guide wire 2 is connected to the terminal 3, and the other end is connected to the regulating switch 4. There can be 3 to 5 sliding guide wires 2, each correspondingly installed in a micro-channel, so that only one sliding guide wire 2 is installed in each micro-channel, avoiding mutual entanglement and interference. The insertion method...

Abstract

The present invention discloses a catheter capable of adjusting hole size of a head end. The catheter comprises a straight catheter, three sliding guide wires are disposed in a side wall of the straight catheter with an equal interval, front ends of the guide wires are connected with the head end of the catheter, and the rear segment of the catheter is provided with an adjusting switch capable of adjusting the guide wires to extend and retract. The head end hole can be slightly lessened when the catheter is inserted, and the hole can be largened or closed according to the need after the catheter is indwelled. A hole size adjusting function is added to a traditional catheter, the hole is largened to facilitate drainage, and the catheter is prevented from being blocked by blood clots or tissue blocks; and the traditional fact the catheter is closed by external clamp is replaced by closing the head end hole, so that retrograde infection of the catheter can be prevented. The catheter is simple in structure, convenient to manufacture and easy to use.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine and medical equipment, and relates to a catheter with an adjustable hole size at the head end. Background technique [0002] In recent years, the incidence of diseases such as benign prostatic hyperplasia and tumors, bladder tumors, and urinary stones has remained high, and has a tendency to increase year by year. These diseases require routine indwelling catheters after surgery, and bladder irrigation if necessary. However, because the head of the traditional catheters only has two small side holes, it is difficult to meet the various conditions of different patients, so there are often Blood clots or tissue blocks, etc. lead to blockage of the urinary catheter, and severe cases will lead to a second operation, which not only causes great pain to the patient, but also brings a lot of trouble to the medical staff. In addition, the traditional indwelling catheter is clamped at the place ...
