Abstract
The invention discloses a balloon catheter and relates to the technical field of medical devices. The balloon catheter comprises a catheter with a drainage cavity and a flushing cavity, wherein a balloon is arranged at the front part of the catheter, an inlet of the flushing cavity is arranged at the tail end of the catheter, a guide hole communicated with the flushing cavity is formed between the balloon and the inlet of the flushing cavity on the wall of the catheter, and the guide hole is positioned in the range which is 80mm away from the tail end of the balloon. The invention provides the balloon catheter which can prevent a patient from feeling pain when the catheter is drawn, improve the comfort level of the patient and reduce the complications of the patient after the catheter is drawn out.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of device that is used to patient's urethral catheterization clinically.
Background technology
Foley catheter is widely used clinically, but existing three-cavity air bag catheter, be that airbag chamber, drainage lumens and flushing chamber all are arranged in the conduit, these three chambeies respectively are provided with a bifurcated at the end of conduit, airbag chamber ends and the formation air bag in the front portion of conduit, offer and wash the flushing chamber outlet that the chamber is connected at the front end of catheter air bag, front end at catheter air bag offers the drainage lumens entrance that is connected with drainage lumens equally, and this drainage lumens entrance can make urine flow go into drainage lumens and excrete.When extracting catheter, since the catheter outer surface drying, the interior wall friction of normal and urethra, cause patient's pain, or even the urethral mucosa damage, make the patient produce phenomenons such as frequent micturition, dysurea, hematuria, urine retention behind the tube drawing easily, about 20% needs of patients carries out urethral catheterization again.
Summary of the invention
Problem to be solved by this invention provides a kind of Foley catheter, to solve existing Foley catheter, causes the problem of patient's pain even generation complication when extracting.
In order to address the above problem, technical scheme of the present invention is: it comprises the conduit with drainage lumens and flushing chamber this Foley catheter, the front portion of described conduit is provided with air bag, the entrance in described flushing chamber is located at the end of described conduit, offering the guide hole that is communicated with described flushing chamber on the tube wall of described conduit between the entrance in described air bag and described flushing chamber, described guide hole is in the scope of terminal 80 millimeters of the described air bag of distance.
In the technique scheme, more specifically scheme can be: have two described guide holes, the distance of the center of one of them guide hole and described air bag end is 35 millimeters, and the distance of the center of another guide hole and described air bag end is 80 millimeters.The aperture of the described guide hole of close described air bag is 3 millimeters, and the aperture of the described guide hole that the described air bag of distance is far away is 2 millimeters.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
This Foley catheter offers the guide hole that is connected with described flushing chamber in addition at the front end certain position of the described conduit of distance, when extracting this Foley catheter, wash the porch injection medical pharmacy in chamber earlier from the end of conduit, make medicament flow out the lubrication conduit outer surface by the newly-increased guide hole of offering, and anesthetic action arranged, reduce the friction that catheter outer surface and patient's urethra inwall produce, both alleviated the patient extract Foley catheter the time misery, alleviate the inflammatory reaction of patient's urethra local mucous membrane again, greatly reduced patient infection's probability.The patient who adopts this Foley catheter to use by above method generally believes no any discomfort and pain, the functional rehabilitation that is conducive to patient's voluntary micturition, reduce slotting rate and the urinary tract infection again of catheter, the effectively generation of dysuria and urine retention behind the prevention tube drawing has positive effect to the prevention urinary system infection.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing enforcement:
Foley catheter shown in Figure 1 comprise have airbag chamber 1, the conduit 4 in drainage lumens 2 and flushing chamber 3, these three chambeies respectively are provided with a bifurcated at the end of conduit 4, the front portion of conduit 4 is provided with air bag 7, this air bag 7 by airbag chamber 1 in the front portion of conduit 4 by and form.The front portion of conduit 4 is provided with drainage lumens entrance 9, and drainage lumens entrance 9 has two, opens respectively in the both sides of drainage lumens 2, and drainage lumens entrance 9 can make urine flow go into drainage lumens 2 and excrete.Flushing chamber entrance is located at the end of conduit 4, between air bag 7 and flushing chamber entrance, offering the guide hole that is communicated with flushing chamber 3 on the tube wall of conduit 4, guide hole is in the scope apart from terminal 80 millimeters of air bag 7, this scope must be less than the length of human body urethra, with the medical pharmacy that guarantees to inject from flushing chamber 3 can be in the sufficient lubrication of human body urethra, in this scope, have two described guide holes, the distance L of the center of one of them guide hole 6 and air bag 7 ends
2Be 35 millimeters, the distance L of the center of another guide hole 5 and air bag 7 ends
1It is 80 millimeters.Aperture near the guide hole 6 of air bag 7 is 3 millimeters, and the aperture of the guide hole 5 far away apart from air bag 7 is 2 millimeters.Medical pharmacy (this medicament is the intermixture of sterilization paraffin oil 5ml+ dexamethasone injection 5mg+2% lignocaine injection 5ml+ normal saline 5ml) injects from the entrance in the flushing chamber 3 of catheter tip in elder generation when extracting this Foley catheter, part medicament is by newly-increased guide hole 5,6 lubrication conduits, 4 outer surfaces of offering, and anesthetic action arranged, reducing the friction of conduit 4 outer surfaces and patient's urethra inwall generation pulls, both alleviated the patient extract Foley catheter the time misery, the inflammatory reaction that has alleviated patient's urethra local mucous membrane again.Another part medicament enters bladder from the flushing chamber outlet 8 of catheter proximal end.
Claims (2)
1. Foley catheter, comprise the conduit with drainage lumens and flushing chamber, the front portion of described conduit is provided with air bag, the entrance in described flushing chamber is located at the end of described conduit, it is characterized in that: offering the guide hole that is communicated with described flushing chamber on the tube wall of described conduit between the entrance in described air bag and described flushing chamber, described guide hole is in the scope of terminal 80 millimeters of the described air bag of distance; Have two described guide holes, the distance of the center of one of them guide hole and described air bag end is 35 millimeters, and the distance of the center of another guide hole and described air bag end is 80 millimeters.
