Abstract

The utility model discloses a calabash-shaped balloon urethral catheter. The urethral catheter is composed of a three-cavity tube and a balloon, wherein the balloon is composed of a urethra part and a bladder part, and the balloon presents a calabash shape after inflation. The utility model which is designed according to the shape of the prostate fossa of a human body has the advantages of effects on good hemostasis and drainage, and comfortable use for patients. The utility model is a balloon urethral catheter which can be widely used for hemostasis and drainage after prostate operation.

Description

A kind of Pear-Shaped Foley catheter

This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of Foley catheter that uses behind operation on prostate.

The invention of Foley catheter becomes a reality prostatic operation.Be applied to the hemostasis behind the operation on prostate and the Foley catheter of urethral catheterization at present and generally be divided into Three-channel single-sac catheter and four chambeies, two capsule catheters, its air bag is sphere.Single capsule catheter places the hemostasis by compression of prostate nest with the water-filling air bag after operation, to such an extent as to the bladder neck compressing is not good, hemorrhage more; If the water-filling air bag is placed bladder neck, the tractive hemostasis by compression fails to oppress the prostate nest again, and prostate nest place's bleeding time is long, can't reach timely hemostatic purpose.Simultaneously, the water-filling air bag places bladder neck, and bladder inner segment pipe is long, usually can cause inadequate drainage and more irritation sign of bladder.Chinese patent ZL95233437.2 discloses a kind of novel haemostatic catheter, and this utility model divides two sacculus three chambeies and two sacculus four chamber haemostatic catheters to form, and its air bag is made up of two spherical envelope of size.Because gapped between two air bags, air bag and make that bladder neck position haemostatic effect is poor in the tractive well; Equally also there is the long drawback of bladder inner segment pipe.And, the stressed optimum of spherical envelope be with the vertical sphere of urethra on, stressed inequality makes patient's postoperative that in various degree pain all be arranged; Two air bags have increased difficulty of processing, and the drain tract is dwindled, and cause inadequate drainage.

This utility model has purpose to be to provide a kind of hemostasis drainage effect good, and the patient uses comfortable Pear-Shaped Foley catheter.

The purpose of this utility model is achieved in that the Pear-Shaped Foley catheter is made up of three lumens and air bag, and its air bag per urethram part and bladder with partial is formed, and expanding afterwards is Pear-Shaped; The urethra part wall thickness of air bag is 1.5-2.5 a times of bladder with partial wall thickness; The urethra partial-length of air bag is 1.0～2.0 times of bladder with partial length.

This utility model is according to the form design of human body prostate nest, outwards traction behind the air bag water-filling, can seamlessly clog the prostate nest, can oppress bladder neck again, contact area is big, haemostatic effect is good, and air bag is stressed evenly to alleviate the patient suffering greatly, and the bladder segment length shortens, less stimulation bladder, flushing and drainage effect are good.

Below with reference to the accompanying drawings this utility model is elaborated.

Fig. 1 is this utility model sketch map;

Fig. 2 is the generalized section of this utility model air bag;

Fig. 3 is a functional schematic of the present utility model.

The Pear-Shaped Foley catheter is made up of three lumens 3 and Pear-Shaped air bag 2 as shown in Figure 1.Three chambeies are arranged in the pipe of three lumens 3, and the tail end of three lumens has three to be in charge of, and middle lumen 5 is thicker, communicates with bladder by aperture on the tube head 1, and make drainage tube and use: side pipe 6 communicates with bladder by aperture on the tube head 8, makes syringe pipe usefulness; Side pipe 4 has an aperture to lead to air bag, can be to airbag aeration or water filling.

As shown in Figure 2, Pear-Shaped air bag 2 is part 10 and bladder with partial 9 compositions per urethram, and urethra part 10 wall thickness are 1.5-2.5 times of bladder with partial 9 wall thickness; Urethra part 10 length are 1.0-2.0 times of bladder with partial 9 length.

User mode of the present utility model, is inserted the Pear-Shaped Foley catheter in the bladder 11 from external orifice of urethra behind prostate excision by shown in Figure 3, injects an amount of normal saline by side pipe 4 in air bag 2, makes airbag inflation, is Pear-Shaped.The urethra part 10 of air bag is close to prostate nest 13, and the bladder with partial 9 of air bag is close to bladder neck 12, adapts to the physiological structure of human body fully, the most normal bleeding part of compressing each point, and hemostasis has efficiently and effectively been avoided oozing of blood to overflow into bladder simultaneously and has been formed clot.
