Description

Dual Lumen Single Bladder Irrigation Catheter

technical field

The utility model belongs to the field of medicine and hygiene, in particular to a double-chamber single-bag bladder irrigation catheter.

Background technique

At present, the bladder irrigation catheter used in the hospital is mainly a catheter with an air bag made of materials such as latex, natural rubber, silicon rubber or polyvinyl chloride. After the catheter is inserted into the bladder, saline or gas is injected into the balloon cavity for internal fixation of the bladder. According to different irrigation methods, there are mainly two types of urinary catheters clinically, one is a three-lumen catheter, and the other is a two-lumen catheter. One lumen of the three-lumen urinary catheter leads to the air bag, and the other two lumens are irrigation lumens and drainage lumens. Two-lumen urinary catheter, one lumen leads to the balloon, and the other lumen is the drainage lumen.

If a three-lumen urinary catheter is used to flush the bladder, the flushing fluid enters the bladder through the mouth of the flushing tube, and then stays for a period of time before being drained into the urine bag through the drainage tube. If flushing is not performed, the flushing tube end of the three-chamber urinary catheter is exposed to the air. Since there is no special stopper to close this end, the syringe needle cap is often blocked clinically. This operation has several disadvantages: one is that the workload of the nursing staff is increased, and the operation is not too convenient; Bacterial retrograde infection.

If a two-lumen catheter is used to flush the bladder, there are two clinical methods: one is to drain the urine from the drainage tube first, clamp the catheter body with a flow-limiting clip, disinfect and pull it out At the junction of the drainage bag and the drainage tube, connect the mouth of the drainage tube with the pipeline for bladder irrigation with a sterile joint, and then open the restrictor clip for irrigation. After rinsing, disinfect the mouth of the drainage tube and replace the connector of the drainage bag. The disadvantage of this method is that it is extremely cumbersome, and the operation is very inconvenient, and it also requires special aseptic joints and matching flushing pipelines. Another commonly used method is to directly puncture the drainage tube with the infusion needle without pulling out the drainage tube connector during flushing, and then fix the needle handle on the side wall of the drainage tube with adhesive tape. This method is much more convenient than the previous method, but there are still disadvantages: 1. Nursing staff often need to fix the needle handle with one hand, and at the same time assist the other hand to tear the adhesive tape and fix the needle handle on the arc-shaped drainage tube . Because the common width of the current needle handle is 1.4 cm, it is straight, and the diameter of the catheter drainage lumen is 1 cm, which is curved, which makes it very inconvenient to stick the adhesive tape. Two, the side of the drainage tube on the urinary catheter is next to the air bag cavity, and the air bag cavity will interfere with the nursing staff to paste the adhesive tape, increasing the difficulty of pasting the adhesive tape. 3. The needle handle is easy to shift. The needle tip has already entered the drainage tube cavity. The displacement of the needle handle may cause the needle tip to puncture the drainage tube again, causing the needle tip to block, or even penetrate too deep, causing the air bag cavity to be punctured and cause water leakage or Gas, causing the fixed balloon in the bladder of the catheter to shrink and make the catheter slip off.

Contents of the invention

The purpose of this utility model is to provide the market with a novel design, no need to prepare additional aseptic joints and special irrigation tubes for bladder irrigation (replaced by ordinary disposable aseptic infusion sets that are very common in clinical practice), and no need to prepare additional adhesive tape , It is not easy to leak urine, not easy to retrograde infection, the air bag cavity is not easy to be punctured by mistake, and the nursing operation is simple.

The technical scheme of the utility model is: it comprises catheter tube body, air bag, air bag cavity, drainage lumen etc., and a needle handle fixing platform is set on the side wall of the drainage lumen, and the length of the fixing platform is 0.8~ 2cm, width 1.2~1.5cm, set on the side wall within the length range of 3~3.5cm at the end of the drainage lumen. A needle handle fixing belt is provided on the side drainage lumen wall of the platform, and the second half of the needle handle fixing belt is coated with an adhesive layer that can be pasted repeatedly on the surface opposite to the platform, and the adhesive layer surface is provided with an adhesive tape protective layer.

The beneficial effects of the utility model are: not only the design is novel, but also the operation is very convenient, and the occurrence rate of leakage of urine, retrograde infection, false puncture of the air bag cavity, slippage of the catheter, etc. is greatly reduced. Since this bladder irrigation catheter does not need to prepare additional sterile joints and special irrigation tubes (it can be replaced by ordinary disposable sterile infusion sets that are very common in clinical practice), this will greatly reduce the preparation and operation of bladder irrigation items. cumbersome. Because the end of the novel urinary catheter has a fixed platform and an adhesive tape, it is very convenient to operate when fixing the needle handle, greatly improves the nursing efficiency, and can be used repeatedly during multiple flushes. The double-chamber single-bag bladder irrigation catheter has obvious advantages and good social and economic benefits.

Below in conjunction with accompanying drawing, the utility model is further described.

Description of drawings:

Figure 1 is a schematic diagram of the overall structure of the utility model.

Among the figure: 1 is the catheter tube body, 2 is the air bag, 3 is the air bag cavity, 4 is the one-way valve of the air bag, 5 is the drainage lumen, 6 is the fixed platform, 7 is the fixing belt, 8 is the adhesive layer, 9 is a needle handle, and 10 is a sterile connector.

Detailed ways:

As shown in Figure 1, the double-chamber single-bladder bladder irrigation catheter is composed of a catheter body 1, an air bag 2, an air bag cavity 3, and a drainage lumen 5. The flap 4 and the drainage lumen 5 are connected with the urine bag through a sterile connector 10 . A needle handle fixing platform 6 is arranged on the side wall of the drainage lumen 5, the length of the fixing platform 6 is 0.8-2 cm, and the width is 1.2-1.5 cm, and it is set at the end of the drainage lumen 5 within the length range of 3-3.5 cm. on the side wall. And a needle handle fixing band 7 is set on the drainage lumen wall on one side of the platform, the width of the needle handle fixing band 7 is the same as the length of the fixing platform 6, and the length is 2.5-3 cm. The second half of the surface of the fixing belt 7 opposite to the platform is coated with an adhesive layer 8 that can be pasted repeatedly, and the surface of the adhesive layer 8 is provided with an adhesive tape protective layer.

When implementing the utility model, take the 16Fr/ch 30ml/cc catheter as an example, the catheter drainage lumen 5 has an outer diameter of 1cm, a wall thickness of 1mm, and the length of the drainage lumen mouth from the Y-shaped bifurcation is 5cm. A fixed platform 6 with a length of 1.5 cm and a width of 1.4 cm is added to the side wall at a distance of 5 mm from the port, and a fixed belt 7 with a length of 2.8 cm and a width of 1.5 cm is arranged on the inside of the platform.

Before bladder irrigation, the insertion method of the urinary catheter is the same as that of the Foley catheter. The medical staff first inserts the catheter into the patient's bladder, and then continues to insert a few centimeters after seeing that the urine flows out, and then passes through the one-way valve 4-way. Physiological saline or gas is injected into the balloon 2 for bladder internal fixation. The urine in the patient's bladder enters the urine bag from the catheter. When performing bladder flushing, the medical personnel clamp the drainage pipe of the urine bag with a flow-limiting clamp or blood vessel clamp, and then insert the needle of an ordinary disposable sterile infusion set from the upper front of the fixed platform 6 on the catheter drainage lumen 5 In the drainage lumen 5, place the needle handle 9 flat on the fixed platform 6, tear off the adhesive paper on the inner side of the fixing belt 7, fix the needle handle 9 on the drainage lumen 5, and open the limit of the disposable sterile infusion set. The flushing fluid enters the bladder from the drainage lumen 5, and the bladder can be flushed. After flushing, remove the fixing band 7, pull out the needle of the infusion set, and then stick the fixing band on the wall of the drainage tube lumen 5, so as to be pasted repeatedly for the next bladder flushing. The double-chamber single-capsule bladder irrigation catheter has the advantages of reasonable structure, simple manufacture, convenient use, repeated sticking, safety and sanitation, etc., and can be widely used in patients who need bladder irrigation.
