Abstract
The invention discloses a catheter and belongs to the field of a medical instrument. The catheter comprises airbags and an inflating port, wherein the airbags are arranged on the head part of the catheter; the inflating port is formed in the tail part; the airbags are a plurality of small airbags which are distributed along one section of a pipe body and are arranged around the pipe body; after being filled with gas/liquid, the outer diameter of each small airbag is greater than the outer diameter of the catheter. Due to the fact that the airbags filled with the gas/liquid play the role of fixing the catheter, and after being deflated, the airbags do not protrude, the catheter drawing resistance and the damage to a urethra mucosa can be effectively reduced, and the pain of the patient is relieved.
Description
Technical field
The invention belongs to medical mechanical domain, specifically be a kind of catheter.
Background technology
After catheter per urethra inserts bladder, inflate in the air bag near catheter head end, the air bag of expansion can make catheter be fixed on intravesical, not easily deviates from, thus reaches the object connecting urinal collection urine.The head end of the catheter of current use is an air vesicle structure, and when extracting catheter, even if extract out to greatest extent the gas in air bag, expanded air bag still can larger projection, cannot return to initial shape completely.Protruding air bag causes in tube drawing process and occurs pain, later stage dysuria, brings certain misery to patient.
Summary of the invention
Technical problem to be solved by this invention is when catheter needs to extract, the air bag of fixing catheter bleeds/drawing liquid after exist large protruding, cause tube drawing smooth, cause pain and later stage dysuric problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of catheter, comprise the air bag being arranged on catheter head and the inflation port being arranged on afterbody, described air bag is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
Further, the original state of ballonet is to pipe sunken inside.
The present invention changes traditional catheter head end air vesicle structure into some ballonet structure, and some ballonets can reach the object of fixing catheter under less inflation/topping up distortion, and after bleeding when tube drawing, it is without protruding, and can effectively reduce tube drawing resistance.As optimizing structure the original state of ballonet is designed to pipe sunken inside structure, although during tube drawing air bag place cannot return to insufflation gas before duplicate state, at least can return to compared with other position external diameters of body without any projection.Greatly reduce the resistance of tube drawing and the damage to mucous membrane of urethra like this, thus alleviate the misery of patient.

Below in conjunction with drawings and Examples, the present invention is further described.

Detailed description of the invention
Catheter of the present invention, comprise the air bag 1 being arranged on catheter head and the inflation port 2 being arranged on afterbody, air bag 1 is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
When catheter is inserted urethra, air bag 1 is in original state (as depicted in figs. 1 and 2), by inflation port 2 to insufflation gas or liquid in air bag 1, what air bag 1 became expands (as shown in Figure 3 and Figure 4), then by catheter, slowly tractive is to meeting resistance outward, and now explanation air bag 1 plays fixation.During tube drawing, by inflation port 2 place, the gas/liquid in air bag is extracted out, air bag retraction (as shown in Figure 5 and Figure 6).In the present embodiment, air bag 1 original state is to pipe sunken inside, although air bag 1 is difficult to the original state returning to Fig. 1 during tube drawing, now tube drawing also has no resistance.
Claims (2)
1. a catheter, comprise the air bag being arranged on catheter head and the inflation port being arranged on afterbody, it is characterized in that: described air bag is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
2. catheter according to claim 1, is characterized in that: the original state of ballonet is to pipe sunken inside.
